Hydroxyapatite catalyzed hydrothermal liquefaction transforms food waste from an environmental liability to renewable fuel.

    Description: Food waste is an abundant and inexpensive resource for the production of renewable fuels. Biocrude yields obtained from hydrothermal liquefaction (HTL) of food waste can be boosted using hydroxyapatite (HAP) as an inexpensive and abundant catalyst. Combining HAP with an inexpensive homogeneous base increased biocrude yield from 14 ± 1 to 37 ± 3%, resulting in the recovery of 49 ± 2% of the energy contained in the food waste feed. Detailed product analysis revealed the importance of fatty-acid oligomerization during biocrude formation, highlighting the role of acid-base catalysts in promoting condensation reactions. Economic and environmental analysis found that the new technology has the potential to reduce US greenhouse gas emissions by 2.6% while producing renewable diesel with a minimum fuel selling price of $1.06/GGE. HAP can play a role in transforming food waste from a liability to a renewable fuel.

    Quantification of bone surface textures: exploring a new method of ontogenetic ageing (2023)
    In:  Journal of Analytical Science and Technology vol. 14 no. 1
    Details
    Publication Date: 2024-02-26
    Description: Identifcation of ontogenetic age classes plays an important role in the felds of zoology, palaeontology and archaeology, where accurate age classifcations of (sub)fossil remains are a crucial component for the reconstruction \nof past life. Textural ageing\xe2\x80\x94the identifcation of age-related bone surface textures\xe2\x80\x94provides a size-independent \nmethod for age assessment of vertebrate material. However, most of the work so far is limited to qualitative results. \nWhile qualitative approaches provide helpful insights on textural ageing patterns, they are heavily subject to observer \nbias and fall short of quantitative data relevant for detailed statistical analyses and cross-comparisons. Here, we present a pilot study on the application of 3D surface digital microscopy to quantify bone surface textures on the long \nbones of the grey heron (Ardea cinerea) and the Canada goose (Branta canadensis) using internationally verifed \nroughness parameters. Using a standardised measuring protocol, computed roughness values show a strong correlation with qualitative descriptions of textural patterns. Overall, higher roughness values correspond to increased numbers of grooves and pits and vice versa. Most of the roughness parameters allowed distinguishing between diferent \nontogenetic classes and closely followed the typical sigmoidal animal growth curve. Our results show that bone \ntexture quantifcation is a feasible approach to identifying ontogenetic age classes.

    Global consortium for the classification of fungi and fungus-like taxa (2023)
    Mushroom Research Foundation
    In:  Mycosphere vol. 14 no. 1, pp. 1960-2012
    Details
    Publication Date: 2024-04-22
    Description: The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the Outline of Fungi and funguslike taxa, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the Outline of Fungi website (https://www.outlineoffungi.org/), and these will be finally published in the biannual edition of the Outline of Fungi and fungus-like taxa. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, ‘to promote a more stable taxonomy in Fusarium given the divergences over its generic delimitation’, or ‘are there too many genera in the Boletales?’ and even more importantly, ‘what should be done with the tremendously diverse ‘dark fungal taxa?’ There are undeniable differences in mycologists’ perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others’ work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa. Interested parties should contact the lead author if they would like to be involved in future outlines.

    The genus Gautieria (Gomphales) in Europe and the Mediterranean Basin: a morphological and phylogenetic taxonomic revision (2023)
    Naturalis Biodiversity Center
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 50 no. 1, pp. 48-122
    Details
    Publication Date: 2024-04-02
    Description: Type material and additional collections of 11 taxa of Gautieria described in Europe and North Africa have been studied, namely G. dubia, G. graveolens, G. morchelliformis var. globispora, G. morchelliformis var. magnicellaris, G. morchelliformis var. morchelliformis, G. morchelliformis var. stenospora, G. otthii, G. pseudovestita, G. retirugosa, G. trabutii and G. villosa. At the same time, morphological and genetic studies on recent and herbarium collections from several European countries have been carried out. This enabled clarification of sections within Gautieria and differentiation of 28 taxa, of which 21 are new to science. However, the deeper relationships and nomenclature changes related to the phylogenetic position of the genus Gautieria within Gomphaceae will not be addressed in this study because they would require a more complete molecular analysis together with that of related genera, e.g., Gomphus, Turbinellus, and the four subgenera of Ramaria. In addition, a lectotype for G. villosa var. villosa and reference specimens for G. graveolens and G. morchelliformis var. morchelliformis are selected, and the new combination G. morchelliformis var. dubia is proposed. Detailed descriptions, macro- and microphotographs and distribution maps of all taxa are provided, as well as extensive information on their ecology, chorology and phylogeny. A key is included to facilitate identification of taxa.

    A fifty-locus phylogenetic analysis provides deep insights into the phylogeny of Tricholoma (Tricholomataceae, Agaricales) (2023)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 50 no. 1, pp. 1-26
    Details
    Publication Date: 2024-03-27
    Description: As an ectomycorrhizal fungal genus that contains matsutake and other edible mushrooms, Tricholoma has great economic and ecological significance. However, the phylogenetic relationships within the genus remain unsettled. To clarify the infrageneric relationships of Tricholoma, including the identification of monophyletic subgenera and sections, three phylogenetic analyses were conducted employing single-locus (ITS), five-locus (ITS/ RPB2/EF-1α/MCM7/mtSSU) and 50-locus (45 single-copy orthologous genes plus the aforementioned ones) DNA nucleotide sequences. Our data indicated that ITS sequences could serve the species delimitation of Tricholoma in most cases and monophyletic groups recognition in some cases, and the five-locus dataset could resolve a section-level phylogeny of this genus, while the 50-locus dataset could clarify the delimitation of subgenera and settle the relationships among sections within this genus. A fifty-locus dataset was firstly employed to construct a robust phylogeny of Tricholoma. Based on this, a new infrageneric arrangement for the genus Tricholoma, with four subgenera, of which two are in accordance with the previous subgenera Pardinicutis and Sericeicutis, and eleven sections, is suggested. Subgenus Pardinicutis, occupying the basal position, only harbors sect. Pardinicutis, while the subg. Sericeicutis comprises sects. Lasciva and Sericella located at the sub-basal position with good support. Subgenus Terrea is newly erected here and consists of sect. Terrea, sect. Atrosquamosa and two as yet unnamed phylogenetic lineages. Besides an unnamed section-level lineage, subg. Tricholoma consists of sects. Genuina, Muscaria, Rigida, Tricholoma, Fucata and Matsutake, of which the two latter are newly proposed. The previously defined subg. Contextocutis is clustered within subg. Tricholoma and is a synonym of the latter. Tricholoma colossus, T. acerbum and their allies, which used to be allocated in sect. Megatricholoma (or genus Megatricholoma), are relocated to sect. Genuina since they form a strongly supported monophyletic group and share rusty or black spots on lamellae with other species in this section. Taxonomic descriptions of the new infrageneric taxa and a key to subgenera and sections of the genus Tricholoma are presented.

    Overview of the European species of the genus Clitocella (Entolomataceae, Agaricales) with notes on extralimital taxa (2023)
    Naturalis Biodiversity Center
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 50 no. 1, pp. 123-157
    Details
    Publication Date: 2024-04-08
    Description: A revision, based on morphological and multigene analysis, of the Clitocella species currently present in Europe is provided. Portions of nrITS rDNA, nr28S rDNA (LSU), RNA polymerase II second largest subunit (RPB2), translation elongation factor 1-alpha (EF-1α), and ATPase subunit 6 (ATP6), were used to sort out the relationships of the species within the genus. Three subgenera were recognized: Clitocella subg. Clitocella encompassing C.popinalis, C.colorata, C.mundula, C.nigrescens, C.obscura and the new species C.solaris from Switzerland; the new Clitocella subg. Paraclitopilus including C.fallax and C.blancii; and the new Clitocella subg. Rhodopleurella for accommodating C. termitophila, a peculiar entity characterized by a pleurotoid habit and growing on decaying, abandoned termite nests in the Dominican Republic. Clitocella colorata originally described from China is here reported and described for the first time in Europe (Italy and Estonia). Rhodocybe cupressicola and Clitopilus ammophilus are reduced to later synonyms of Rhodopaxillus nigrescens; similarly, Clitopilus amarus is treated as a later synonym of Omphalia fallax while Rhodocybe amarella and R. ochraceopallida of Rhodopaxillus blancii. Finally, Austrian and Swedish herbarium collections identified as Rhodocybe, a doubtful taxon considered by several modern authors occasionally as either a similar but distinct species from R.popinalis or as a dwarfish, puny and odourless form of R. popinalis, have been proved to be R. tugrulii, a species recently described from Turkey and Estonia, and also later reported from Italy and USA.

    Wild rodents harbour high diversity of Arthroderma (2023)
    Naturalis Biodiversity Center
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 50 no. 1, pp. 27-47
    Details
    Publication Date: 2024-04-08
    Description: Arthroderma is the most diverse genus of dermatophytes, and its natural reservoir is considered to be soil enriched by keratin sources. During a study on the diversity of dermatophytes in wild small rodents in the Czech Republic, we isolated several strains of Arthroderma. To explore the diversity and ecological significance of these isolates from rodents (n = 29), we characterised the strains genetically (i.e., sequenced ITS, tubb and tef1α), morphologically, physiologically, and by conducting mating experiments. We then compared the rodent-derived strains to existing ITS sequence data from GenBank and the GlobalFungi Database to further investigate biogeography and the association of Arthroderma species with different types of environments. In total, eight Arthroderma species were isolated from rodents, including four previously described species (A. crocatum, A. cuniculi, A. curreyi, A. quadrifidum) and four new species proposed herein, i.e., A. rodenticum, A. simile, A. zoogenum and A. psychrophilum. The geographical distribution of these newly described species was not restricted to the Czech Republic nor rodents. Additional isolates were obtained from bats and other mammals, reptiles, and soil from Europe, North America, and Asia. Data mining showed that the genus has a diverse ecology, with some lineages occurring relatively frequently in soil, whereas others appeared to be more closely associated with live animals, as we observed in A. rodenticum. Low numbers of sequence reads ascribed to Arthroderma in soil show that the genus is rare in this environment, which supports the hypothesis that Arthroderma spp. are not soil generalists but rather strongly associated with animals and keratin debris. This is the first study to utilise existing metabarcoding data to assess biogeographical, ecological, and diversity patterns in dermatophytes.

    Living coccolithophore communities in the central Mediterranean Sea (Summer 2016): Relations between ecology and oceanography (2022)
    Elsevier
    Details
    Publication Date: 2022-03-17
    Description: Coccolithophores were collected at 21 stations during summer 2016, from coastal and offshore areas of the Central Mediterranean Sea, to describe the ecology of the coccolithophore community integrating information on their abundance, environmental parameters (salinity, temperature, dissolved oxygen, and fluorescence) and oceanographic data. Emiliania huxleyi dominated the assemblage from surface to intermediate layers, while Florisphaera profunda was more abundant in the deep photic zone. Principal Component Analysis revealed that the distribution of coccolithophore taxa was influenced by environmental parameters: K-strategist taxa were related to warm surface waters, whereas lower photic zone taxa were influenced by the development of a Deep Chlorophyll Maximum and high salinity values, well below the thermocline. These results confirmed that a vertical species zonation, as a typical feature of low-middle latitude, characterizes the Central Mediterranean during summer. The distribution of F. profunda once again confirmed its use as a proxy of Deep Chlorophyll Maximum development and paleoproductivity estimates. Gephyrocapsa spp. (=total Gephyrocapsa), and in particular G. oceanica, were more abundant along the Atlantic Water pathway. Finally, the high concentration value of Helicosphaera carteri, recorded in the Ligurian Sea at an offshore station, suggested an expansion of the opportunist nature of this taxon from coastal environments to the offshore areas characterized by high turbidity and high productivity.

New opportunities and untapped scientific potential in the abyssal ocean. Frontiers in Marine Science, 8, (2022): 798943, https://doi.org/10.3389./fmars.2021.798943
    Description: The abyssal ocean covers more than half of the Earth’s surface, yet remains understudied and underappreciated. In this Perspectives article, we mark the occasion of the Deep Submergence Vehicle Alvin’s increased depth range (from 4500 to 6500 m) to highlight the scientific potential of the abyssal seafloor. From a geologic perspective, ultra-slow spreading mid-ocean ridges, Petit Spot volcanism, transform faults, and subduction zones put the full life cycle of oceanic crust on display in the abyss, revealing constructive and destructive forces over wide ranges in time and space. Geochemically, the abyssal pressure regime influences the solubility of constituents such as silica and carbonate, and extremely high-temperature fluid-rock reactions in the shallow subsurface lead to distinctive and potentially unique geochemical profiles. Microbial residents range from low-abundance, low-energy communities on the abyssal plains to fast growing thermophiles at hydrothermal vents. Given its spatial extent and position as an intermediate zone between coastal and deep hadal settings, the abyss represents a lynchpin in global-scale processes such as nutrient and energy flux, population structure, and biogeographic diversity. Taken together, the abyssal ocean contributes critical ecosystem services while facing acute and diffuse anthropogenic threats from deep-sea mining, pollution, and climate change.

T., Ponz-Segrelles, G., Glasby, C. J., Ribeiro, R. P., Nakamura, M., Oguchi, K., Omori, A., Kohtsuka, H., Fisher, C., Ise, Y., Jimi, N., & Miura, T. Ramisyllis kingghidorahi n. Sp., a new branching annelid from Japan. Organisms Diversity & Evolution. (2022), https://doi.org/10.1007/s13127-021-00538-4.
    Description: Among over 20,000 species of Annelida, only two branching species with a highly modified body-pattern are known until now: the Syllidae Syllis ramosa McIntosh, 1879, and Ramisyllis multicaudata Glasby et al. (Zoological Journal of the Linnean Society, 164, 481–497, 2012). Both have unusual ramified bodies with one head and multiple branches and live inside the canals of host sponges. Using an integrative approach (combining morphology, internal anatomy, ecology, phylogeny, genetic divergence, and the complete mitochondrial genome), we describe a new branching species from Japan, Ramisyllis kingghidorahi n. sp., inhabiting an undescribed species of Petrosia (Porifera: Demospongiae) from shallow waters. We compare the new species with its closest relative, R. multicaudata; emend the diagnosis of Ramisyllis; and discuss previous reports of S. ramosa. This study suggests a much higher diversity of branching syllids than currently known. Finally, we discuss possible explanations for the feeding behaviour in the new species in relation to its highly ciliated wall of the digestive tubes (especially at the distal branches and anus), and provide a hypothesis for the evolution of branching body patterns as the result of an adaptation to the host sponge labyrinthic canal system.

    Description: Ridsdalea philippinensis (Rubiaceae), a new species from the karst forest in El Nido (Palawan, Philippines), is described and illustrated. It is unique among Malesian Ridsdalea species in having a corolla tube that is distinctly inflated at the apex, a character state also displayed by R. sootepensis and R. thailandica from Laos and Thailand. Amongst others, R. philippinensis, however, differs from both of these species in having smaller flowers and anthers that do not emerge from the corolla tube. An updated key for Philippine Ridsdalea is also presented.

    Curcuma stahlianthoides Zingiberaceae , a new species from northeastern Thailand dispersed by ants (2022)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 67 no. 1, pp. 71-75
    Details
    Publication Date: 2024-05-06
    Description: Curcuma stahlianthoides, a new species of Curcuma subg. Hitcheniopsis (Zingiberaceae: Zingiberoideae) from northeastern Thailand is described and illustrated here. The flower morphology of C. stahlianthoides resembles several other species formerly classified in the genus Stahlianthus, but the inflorescences are composed of up to 11 plain green fertile bracts, conforming to the typical inflorescence structure in the genus Curcuma. This combination of characters is similar to C. leonidii from Vietnam, to which it is compared for the diagnostic purposes. Previous molecular results indicate that Stahlianthus should be merged with Curcuma subg. Hitcheniopsis and C. stahlianthoides is the second species providing morphological justification to do so. A detailed description based on living flowering material, colour plates including the flower dissection, and notes on distribution, habitat and phenology are also provided. The status of Vulnerable is proposed for this species based on the IUCN guidelines and criteria. Observations on ant-aided seed dispersal of this species are reported and discussed within present knowledge of myrmecochory in gingers.

    Genetic population structure of the agaric Blastosporella zonata (Lyophyllaceae) reveals cryptic species and different roles for sexual and asexual spores in dispersal (2022)
    Naturalis Biodiversity Center
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 49, pp. 195-200
    Details
    Publication Date: 2024-04-23
    Description: Blastosporella zonata is one of the few basidiomycete fungi that produce asexual spores (conidia) on the mushroom. The role of these conidia in the fungal lifecycle is not known. We tested whether conidia are being utilized in local dispersal by looking for signatures of clonality in 21 samples from three localities separated by about three kilometres in Murillo, Colombia. To identify clonally related individuals, we sequenced three polymorphic markers at two unlinked loci (nuclear rRNA: ITS and LSU, and TEF1α) for all collections plus three herbarium samples. We identified two sets of clonally related individuals growing closely together in one of the three localities, and only one pair shared between localities. In all three localities we observed multiple non-clonally related dikaryons showing that sexual reproduction is also important. Our results indicate that the conidia on the mushroom are primarily important for local dispersal. Unexpectedly, our results also indicate two reproductively isolated populations, possibly representing cryptic biological species.

    Eight new Halophytophthora species from marine and brackish-water ecosystems in Portugal and an updated phylogeny for the genus (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 48, pp. 54-90
    Details
    Publication Date: 2024-03-24
    Description: During an oomycete survey in December 2015, 10 previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds and channels in saltmarshes, lagoon ecosystems and river estuaries at seven sites along the Algarve coast in the South of Portugal. Phylogenetic analyses of LSU and ITS datasets, comprising all described Halophytophthora species, the 10 new Halophytophthora taxa and all relevant and distinctive sequences available from GenBank, provided an updated phylogeny of the genus Halophytophthora s.str. showing for the first time a structure of 10 clades designated as Clades 1–10. Nine of the 10 new Halophytophthora taxa resided in Clade 6 together with H. polymorphica and H. vesicula. Based on differences in morphology and temperature-growth relations and a multigene (LSU, ITS, Btub, hsp90, rpl10, tigA, cox1, nadh1, rps10) phylogeny, eight new Halophytophthora taxa from Portugal are described here as H. brevisporangia, H. celeris, H. frigida, H. lateralis, H. lusitanica, H. macrosporangia, H. sinuata and H. thermoambigua. Three species, H. frigida, H. macrosporangia and H. sinuata, have a homothallic breeding system while the remaining five species are sterile. Pathogenicity and litter decomposition tests are underway to clarify their pathological and ecological role in the marine and brackish-water ecosystems. More oomycete surveys in yet undersurveyed regions of the world and population genetic or phylogenomic analyses of global populations are needed to clarify the origin of the new Halophytophthora species.

    Description: Circinotrichum, Gyrothrix and Vermiculariopsiella represent a complex of dematiaceous, setose, saprobic hyphomycetes that are commonly collected on plant litters in tropical, subtropical to temperate climates. Multi-locus analysis (ITS, LSU, rpb2) and morphological studies revealed that Gyrothrix and Circinotrichum are polyphyletic and species belong to 10 genera grouping in three different clades within Xylariales, named Coniocessiaceae (Circinotrichum and Pirozynskiomyces gen. nov.), Microdochiaceae (Selenodriella and the resurrected genus Peglionia) and the new family Gyrothricaceae (Gyrothrix, Xenoanthostomella, Neogyrothrix gen. nov., Pseudocircinotrichum gen. nov., and Pseudoceratocladium gen. nov.). Vermiculariopsiella (Vermiculariopsiellales, Vermiculariopsiellaceae) is emended for species with setose sporodochia with simple setae (V. dichapetali, V. eucalypticola, V. immersa, V. pini, V. spiralis, V. australiensis sp. nov.) while Vermiculariopsis is resurrected and includes setose fungi with branched setae (Vs. dunni, Vs. eucalypti, Vs. eucalyptigena, Vs. lauracearum, Vs. microsperma, Vs. pediculata and Vs. castanedae sp. nov.).

    Description: Based on phylogenetic analyses of a multi-gene matrix of nuITS-LSU rDNA, RPB2 and TUB2 sequences and morphology, xylariaceous species with uni- to pauciperitheciate stromata and ascospores having a spirally coiling (helicoid) germ slit are revised and reclassified, including detailed descriptions and illustrations. The genus Helicogermslita is redefined and restricted to seven species with massive, erumpent, clypeus-like carbonaceous stromata, and Rosellinia somala is combined in Helicogermslita. Within the core Xylariaceae, the poorly known Leptomassaria simplex is shown to be closely related to Anthostoma insidiosum, for which the new genus Oligostoma is established, and Anthostoma rhenanum is demonstrated to be synonymous with O. insidiosum. The new genus Albicollum, characterised by immersed ascomata and a collar of white pseudostromatic tissues surrounding the ostioles, is established for Amphisphaeria canicollis, Anthostoma chionostomum, Sordaria (= Helicogermslita) fleischhakii and Anthostoma vincensii. Anthostoma ostropoides is synomymised with Albicollum canicolle, and Al. berberidicola, Al. longisporum and Al. novomexicanum are described as new species. Rosellinia (= Helicogermslita) gaudefroyi is transferred to the new genus Spiririma. Anthostoma amoenum and Euepixylon udum, both with a poroid germ locus, are shown to be only distantly related, and An. amoenum is reclassified within the asexual genus Digitodochium. Based on phylogeny, the genus Euepixylon is treated as a synonym of Nemania. A new species, Nemania ethancrensonii, which is closely related to the two formerly accepted Euepixylon species (E. sphaeriostomum, E. udum) but strongly deviates from the morphological concept of Euepixylon and Nemania, is described from the eastern USA. The genera Anthostomelloides, Clypeosphaeria, Digitodochium, Emarcaea, Induratia, Linosporopsis, Magnostiolata, Occultitheca and Spiririma are revealed to form a morphologically heterogeneous lineage in a basal position of Xylariaceae. Anthostoma vincensii, Quaternaria simplex and Rosellinia gaudefroyi are lectotypified, and Amphisphaeria canicollis, Anthostoma amoenum, An. rhenanum, An. vincensii, Quaternaria simplex, Rosellinia gaudefroyi and Valsa insidiosa are epitypified. Keys to uni- to pauciperitheciate xylariaceous genera with sigmoid to helicoid germ slits and to species of Albicollum are provided.

    Host-driven subspeciation in the hedgehog fungus, Trichophyton erinacei, an emerging cause of human dermatophytosis (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 48 no. 1, pp. 203-218
    Details
    Publication Date: 2024-04-03
    Description: Trichophyton erinacei is a main cause of dermatophytosis in hedgehogs and is increasingly reported from human infections worldwide. This pathogen was originally described in the European hedgehog (Erinaceus europaeus) but is also frequently found in the African four-toed hedgehog (Atelerix albiventris), a popular pet animal worldwide. Little is known about the taxonomy and population genetics of this pathogen despite its increasing importance in clinical practice. Notably, whether there are different populations or even cryptic species associated with different hosts or geographic regions is not known. To answer these questions, we collected 161 isolates, performed phylogenetic and population-genetic analyses, determined mating-type, and characterised morphology and physiology. Multigene phylogeny and microsatellite analysis supported T. erinacei as a monophyletic species, in contrast to highly incongruent single-gene phylogenies. Two main subpopulations, one specific mainly to Atelerix and second to Erinaceus hosts, were identified inside T. erinacei, and slight differences in the size of microconidia and antifungal susceptibilities were observed among them. Although the process of speciation into two lineages is ongoing in T. erinacei, there is still gene flow between these populations. Thus, we present T. erinacei as a single species, with notable intraspecies variability in genotype and phenotype. The data from wild hedgehogs indicated that sexual reproduction in T. erinacei and de novo infection of hedgehogs from soil are probably rare events and that clonal horizontal spread strongly dominates. The molecular typing approach used in this study represents a suitable tool for further epidemiological surveillance of this emerging pathogen in both animals and humans. The results of this study also highlighted the need to use a multigene phylogeny ideally in combination with other independent molecular markers to understand the species boundaries of dermatophytes.

    Description: Sympoventuriaceae (Venturiales, Dothideomycetes) comprises genera including saprophytes, endophytes, plant pathogens, as well as important animal or human opportunistic pathogens with diverse ecologies and wide geographical distributions. Although the taxonomy of Sympoventuriaceae has been well studied, generic boundaries within the family remain poorly resolved due to the lack of type materials and molecular data. To address this issue and establish a more stable and reliable classification system in Sympoventuriaceae, we performed multilocus phylogenetic analyses using sequence data of seven genes (SSU, ITS, LSU, act1, tub2, tef1 and rpb2) with increased taxon sampling and morphological analysis. The molecular data combined with detailed morphological studies of 143 taxa resolved 22 genera within the family, including one new genus, eight new species, five new combinations and one new name. Finally, we further investigated the evolutionary history of Sympoventuriaceae by reconstructing patterns of lifestyle diversification, indicating the ancestral state to be saprophytic, with transitions to endophytic, animal or human opportunistic and plant pathogens

    Species diversity, phylogeny, endemism and geography of the truffle genus Tuber in China based on morphological and molecular data (2022)

    Description: The genus Tuber (Tuberaceae, Pezizales) is an important fungal group of Ascomycota both economically and ecologically. However, the species diversity, phylogenetic relationships, and geographic distribution of Tuber species in China remains poorly understood, primarily because descriptions of many new species relied heavily on morphological features with molecular data either not sought or ignored. The misapplication of European and North American names further added to confusion regarding the taxonomy of Chinese Tuber species. In this study, we examined more than 1000 specimens from China, and performed a comprehensive phylogenetic analysis for Chinese Tuber species using ITS sequences and multilocus sequence data. To infer the phylogeny of Chinese Tuber spp., 11 molecular datasets were assembled, including a concatenated internal transcribed spacers of the nuc rDNA (ITS), nuc rDNA 28S subunit (LSU), translation elongation factor 1-alpha (tef1-α), and RNA polymerase II subunit (rpb2) dataset as well as 10 ITS datasets (totally including 1435 sequences from 828 collections with 597 newly generated sequences, and 168 sequences from the types of 63 species). Our phylogenetic tree based on a concatenated multilocus dataset revealed that all Chinese Tuber species nested in nine phylogenetic clades (phylogroups), including Aestivum, Excavatum, Latisporum, Macrosporum, Maculatum, Melanosporum, Puberulum, Rufum and Turmericum. Of these, five phylogroups (Macrosporum, Maculatum, Melanosporum, Puberulum and Rufum) are shared across the continents of Asia, Europe and North America; two phylogroups (Aestivum and Excavatum) are shared by Europe and Asia; and the phylogroups Turmericum and Latisporum are endemic only to Asia. Phylogenetic trees based on 10 ITS datasets confirmed the presence of at least 82 phylogenetic species in China. Of these, 53 are identified as known species, including three new records for China, and 25 species are identified as new to science. Of the new species, nine are described and illustrated in this paper, and the others remain unnamed due to the paucity or absence of ascomatal materials. Accordingly, the confirmed, excluded and doubtful Tuber species in China are discussed. Tuber species showed high endemism. Of the 82 phylogenetic species found in China, 68 species occur only in China, six species are also found in other regions in Asia, and only eight species (T. anniae, T. excelsum-reticulatum, T. formosanum, T. maculatum, T. wenchuanense, Tuber sp. CHN-3, Tuber sp. CHN-10 and Tuber sp. CHN-11) are shared with other continents. Most Tuber species have a small and limited distribution in China, but a few, such as T. formosanum and T. parvomurphium, are widely distributed across China. Some phylogenetically closely related species, such as T. liaotongense and T. subglobosum, as well as T. xuanhuaense and T. lijiangense, show a pattern of allopatric distribution.

    Description: During extensive surveys of global Phytophthora diversity 14 new species detected in natural ecosystems in Chile, Indonesia, USA(Louisiana), Sweden, Ukraine and Vietnam were assigned to Phytophthora major Clade 10 based on a multigene phylogeny of nine nuclear and three mitochondrial gene regions. Clade 10 now comprises three subclades. Subclades 10a and 10b contain species with nonpapillate sporangia, a range of breeding systems and a mainly soil- and waterborne lifestyle. These include the previously described P. afrocarpa, P. gallica and P. intercalaris and eight of the new species: P. ludoviciana, P. procera, P. pseudogallica, P. scandinavica, P. subarctica, P. tenuimura, P. tonkinensis and P. ukrainensis. In contrast, all species in Subclade 10c have papillate sporangia and are self-fertile (or homothallic) with an aerial lifestyle including the known P. boehmeriae, P. gondwanensis, P. kernoviae and P. morindae and the new species P. celebensis, P. chilensis, P. javanensis, P. multiglobulosa, P. pseudochilensis and P. pseudokernoviae. All new Phytophthora species differed from each other and from related species by their unique combinations of morphological characters, breeding systems, cardinal temperatures and growth rates. The biogeography and evolutionary history of Clade 10 are discussed. We propose that the three subclades originated via the early divergence of pre-Gondwanan ancestors 〉 175 Mya into water- and soilborne and aerially dispersed lineages and subsequently underwent multiple allopatric and sympatric radiations during their global spread.

    Description: Nolanea is a well-known and long-established subgenus of the genus Entoloma traditionally defined mainly by the mycenoid basidiocarps of the included species. Until now, revisions of this subgenus including molecular data exist only on a regional scale. In this study, the phylogeny of species of Nolanea is analysed based on multi-gene DNA sequences including data of specimens from all continents. New primers are designed for the mitochondrial small subunit and RPB2. The performance of the DNA loci in reconstructing the phylogeny in subg. Nolanea is evaluated. An ancestral state reconstruction is used to infer the character state evolution as well as the importance and reliability of morphological characters used to define subclades below subgeneric rank. Based on the results, seven sections are recognised in Nolanea: the sections Holoconiota, Infularia, Mammosa, Nolanea, Papillata, Staurospora, and the newly described sect. Elegantissima. A large phylogeny based on the fungal barcode rDNA ITS with numerous type sequences is used to evaluate current species concepts. Several names are revealed to be synonyms of older names. Four species new to science are described, namely E. altaicum, E. argillaceum, E.\xe2\x80\xafcornicolor, and E. incognitum. Lectotypes, epitypes or neotypes are designated for E. cetratum, E. clandestinum, E. conferendum, E. cuspidiferum, E. hebes, E. minutum, E. nitens, and E. rhodocylix. The re-evaluation of the limits of subg. Nolanea leads to an altered concept excluding species with distinct, lageniform cheilocystidia. The section Ameides is placed in subg. Leptonia. For several species formerly accommodated in Nolanea, but excluded now, viz., E. lepiotoides, E. rhombisporum, E. subelegans, and E. velenovskyi the taxonomic position remains unclear, because of the yet unresolved phylogeny of the whole genus Entoloma.

    Diversity of Sporocadaceae (pestalotioid fungi) from Rosa in China (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 49 no. 1, pp. 201-260

    Publication Date: 2024-03-20
    Description: Rosa (Rosaceae) is an important ornamental and medicinal plant genus worldwide, with several species being cultivated in China. Members of Sporocadaceae (pestalotioid fungi) are globally distributed and include endophytes, saprobes but also plant pathogens, infecting a broad range of host plants on which they can cause important plant diseases. Although several Sporocadaceae species were recorded to inhabit Rosa spp., the taxa occurring on Rosa remain largely unresolved. In this study, a total of 295 diseased samples were collected from branches, fruits, leaves and spines of eight Rosa species (R. chinensis, R. helenae, R. laevigata, R. multiflora, R. omeiensis, R. rugosa, R. spinosissima and R. xanthina) in Gansu, Henan, Hunan, Qinghai, Shaanxi Provinces and the Ningxia Autonomous Region of China. Subsequently 126 strains were obtained and identified based on comparisons of DNA sequence data. Based on these results 15 species residing in six genera of Sporocadaceae were delineated, including four known species (Pestalotiopsis chamaeropis, Pes. rhodomyrtus, Sporocadus sorbi and Spo. trimorphus) and 11 new species described here as Monochaetia rosarum, Neopestalotiopsis concentrica, N. subepidermalis, Pestalotiopsis tumida, Seimatosporium centrale, Seim. gracile, Seim. nonappendiculatum, Seim. parvum, Seiridium rosae, Sporocadus brevis, and Spo. spiniger. This study also represents the first report of Pes. chamaeropis, Pes. rhodomyrtus and Spo. sorbi on Rosa. The overall data revealed that Pestalotiopsis was the most prevalent genus, followed by Seimatosporium, while Pes. chamaeropis and Pes. rhodomyrtus were the two most prevalent species. Analysis of Sporocadaceae abundance on Rosa species and plant organs revealed that spines of R. chinensis had the highest species diversity.

    Description: During surveys in central Florida of the zombie-ant fungus Ophiocordyceps camponoti-floridani, which manipulates the behavior of the carpenter ant Camponotus floridanus, two distinct fungal morphotypes were discovered associated with and purportedly parasitic on O. camponoti-floridani. Based on a combination of unique morphology, ecology and phylogenetic placement, we discovered that these morphotypes comprise two novel lineages of fungi. Here, we propose two new genera, Niveomyces and Torrubiellomyces, each including a single species within the families Cordycipitaceae and Ophiocordycipitaceae, respectively. We generated de novo draft genomes for both new species and performed morphological and multi-loci phylogenetic analyses. The macromorphology and incidence of both new species, Niveomyces coronatus and Torrubiellomyces zombiae, suggest that these fungi are mycoparasites since their growth is observed exclusively on O. camponoti-floridani mycelium, stalks and ascomata, causing evident degradation of their fungal hosts. This work provides a starting point for more studies into fungal interactions between mycopathogens and entomopathogens, which have the potential to contribute towards efforts to battle the global rise of plant and animal mycoses.

    Publication Date: 2024-04-04
    Description: The genus Fusarium includes numerous important plant and human pathogens, as well as many industrially and commercially important species. During our investigation of fungal diversity in China, a total of 356 fusarioid isolates were obtained and identified from diverse diseased and healthy plants, or different environmental habitats, i.e., air, carbonatite, compost, faeces, soil and water, representing hitherto one of the most intensive sampling and identification efforts of fusarioid taxa in China. Combining morphology, multi-locus phylogeny and ecological preference, these isolates were identified as 72 species of Fusarium and allied genera, i.e., Bisifusarium (1), Fusarium (60), and Neocosmospora (11). A seven-locus dataset, comprising the 5.8S nuclear ribosomal RNA gene with the two flanking internal transcribed spacer (ITS) regions, the intergenic spacer region of the rDNA(IGS), partial translation elongation factor 1-alpha (tef1), partial calmodulin (cam), partial RNApolymerase largest subunit (rpb1), partial RNA polymerase second largest subunit (rpb2) gene regions, and partial β-tubulin (tub2), were sequenced and employed in phylogenetic analyses. A genus-level phylogenetic tree was constructed using combined tef1, rpb1, and rpb2 sequences, which confirmed the presence of four fusarioid genera among the isolates studied. Further phylogenetic analyses of two allied genera (Bisifusarium and Neocosmospora) and nine species complexes of Fusarium were separately conducted employing different multi-locus datasets, to determine relationships among closely related species. Twelve novel species were identified and described in this paper. The F. babinda species complex is herein renamed as the F. falsibabinda species complex, including descriptions of new species. Sixteen species were reported as new records from China.

    Description: Western Ecuador harbours high plant diversity and endemism. The region of Manabí has known intense deforestation over the last decades, but lowland rain forests persist in a network of small forest fragment patches. Here, we describe two new magnoliid tree species from a small privately owned forest fragment known as La Esperanza reserve, in the El Carmen canton (Manabí): Aniba ecuadorica (Lauraceae) and Guatteria esperanzae (Annonaceae). For both species a detailed morphological description, a preliminary conservation status following IUCN criteria, distribution maps and high quality photographs are provided. This represents the second species of Aniba known to occur in western Ecuador, while there are 14 species of Guatteria documented for Ecuador west of the Andes. Aniba ecuadorica is only known from two localities and has a preliminary IUCN conservation status of Critically Endangered, while Guatteria esperanzae is known from six localities and is suggested to be Endangered. Finally, we provide a quick overview of Guatteria species in western Ecuador with a key to the species in the region. The description of these two new tree species underlines the important need of prospection and conservation of the remnant forests in the Manabí region of western Ecuador. We also stress the importance of privately owned forest fragments for biodiversity conservation.

    Description: Historic herbaria can provide a wealth of information on a diversity of topics, including the past occurrence of plants, their abundance, names and uses. However, 16th and 17th century herbaria are rare and very fragile, and can best be studied after digitization. The collection of Naturalis Biodiversity Center in Leiden, the Netherlands, contains two book herbaria by Jacob Breyne (1637–1697) of Danzig (presently Gdańsk, Poland). These herbaria, dated 1659 and 1673, contain a total of 105 specimens in various states of intactness, and with or without original labels. The identity of the specimens in the Leiden Breyne herbaria was not completely assessed previously. Here we discuss the taxa represented within these two historic herbaria as well as the information contained in the handwritten texts within them. The two Breyne herbaria combined were found to contain 62 species, representing 24 plant families. Both herbaria contain several species now rare around Gdańsk, including two species currently considered regionally extinct (Swertia perennis (Gentianaceae) and Dactylorhiza viridis (Orchidaceae)). Labels with the specimens give a range of information on the collecting locations, ecology, abundance and/or use of the species. The Leiden Breyne herbaria reveal changes in the flora of northern Poland over the course of three centuries, as well as pre-Linnaean nomenclature, historic uses of plants and international correspondence between scientists.

    More smooth-spored species of Inocybe (Agaricales, Basidiomycota): type studies and 12 new species from Europe (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 48, pp. 91-149
    Details
    Publication Date: 2024-04-08
    Description: Twelve new species of Inocybe (I. adorabilis, I. comis, I. demetris, I. filiana, I. galactica, I. morganae, I. othini, I. ovilla, I. proteica, I. somae, I. suryana and I. venerabilis) are described from Europe on the basis of detailed morphological and molecular investigation. A portrait of the recently described I. ianthinopes is given. All species are smooth-spored and some pruinose only in the apical part of the stipe, and some on entire length. The new species are compared to 24 type specimens (17 characterized by at least partial ITS sequence data), all of which are described and revised here. Epitypes were selected for two species, I. hirtella and I. sindonia. Based on our studies, we confirm that I. kuehneri and I. sindonia on one hand, and I. subalbidodisca and I. ochroalba on the other, are synonyms and furthermore suggest that I. abietis is synonymous with I. catalaunica, I. exilis with I. rufobrunnea, I. hirtellarum with I. mycenoides, I. lapidicola with I. deianae, I. ochraceolutea with I. sindonia, I. stangliana with I. pelargonium, I. subrubens with I. subhirtella and I. sulfovirescens with I. langei. All of the new species are supported by phylogenetic analyses. Among the 16 previously described species accepted here, 10 are represented by types in the phylogenetic analyses and five by own collections corresponding to the type. Two species, I. eutheloides (remaining doubtful) and I. pallidolutea are only treated morphologically. In summary, we describe as new or verify the taxonomic status and provide or corroborate morphological concepts for 37 smooth-spored species of Inocybe.

    From cradle to grave? A global hotspot and new species of the genus Lobaria discovered in the Himalayas and the Hengduan Mountains (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 48, pp. 150-174
    Details
    Publication Date: 2024-05-02
    Description: In this study, the East Asian diversity of green-algal Lobaria was evaluated by applying both morphological and phylogenetic approaches. A multi-locus phylogenetic analysis of 72 green-algal Lobaria specimens was performed using a three-locus and time-calibrated species-tree approach. The analyses demonstrate that pairs of sexually and vegetatively reproducing lineages split into highly supported monophyletic clades. Taxonomically, 11 green-algal Lobaria species were identified as new to science, while 10 were previously described species. The species differentiated during the Pliocene and Pleistocene. The coincidence of paleoclimatic events with estimated dates of divergence support a bioclimatic hypothesis for species evolution in the green-algal Lobaria. Molecular phylogenies, a summary of diversity, detailed new species descriptions and geographical analyses are provided. Special recognition of species with a long evolutionary history, which merit high conservation priority, will be critical for preserving geographically restricted endemics in the Himalayas and the Hengduan Mountains, where habitat loss is driving rapid declines.

    The Malesian species of Dalechampia (Euphorbiaceae) (2022)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 67 no. 1, pp. 26-32
    Details
    Publication Date: 2024-05-03
    Description: Dalechampia is a mainly South American genus of generally climbing shrubs with usually sharp stiff trichomes in some of the inflorescence parts. The bisexual inflorescences are very condensed and subtended by two, often showy, large bracts. The three pistillate flowers are separate from the staminate subinflorescence (both groups with their own bracts). The staminate subinflorescence contains groups of staminodial-like bractlets that provide resin for female bees or fragrance for male bees. In west Malesia (Sumatra and Java) one indigenous species is found, the climbing D. bidentata, and occasionally cultivars of the subshrub D. spathulata.

    Details
    Publication Date: 2024-05-03
    Description: While someAfrican Floras were continuously revised and several are now almost completed, the Flora of Angola’s ‘Conspectus Florae Angolensis’ still remains incomplete. This applies also for Droseraceae and the genus Drosera. Our study aims to provide an identification key for Drosera ofAngola and the Democratic Republic of the Congo, including all morphological characters of the different Angolan and Congolese taxa. Loans from different herbaria were studied. A list of important morphological characters was combined with data obtained by observations and measurements. Beside the identification key, nine species descriptions with drawings of the main characteristics, distribution maps and SEM-pictures of pollen and seed morphology are provided. The possibility of hybridisation is discussed. Despite difficulties such as varying morphology or hybridisation in some species, the identification key enables researchers to identify specimens by morphological characters.

This report analysed the River Habitat Survey (RHS) and geomorphology data to evaluate the level of habitat quality and the geomorphological characteristics of the River Eden and sub-catchments. RHS data and geomorphological assessment data was collected within the study areas by CEH and Fluvial Environmental Services Ltd. The River Eden and its sub-catchments are being considered as a Special Area for Conservation (SAC) due to the presence of habitat types and species, which are rare or threatened within Europe. The purpose of the project is to provide an overview of the state of the catchment in terms of river habitats and geomorphological processes in order to aid the derivation of sound management for this proposed SAC.The aim of this report was to determine the state of the environment within the Eden and sub-catchments and identify the main pressures on the system in order to derive sound management options.

In 1996 the National Rivers Authority (NRA) report on the 1992 strategic stock assessment for the Upper Derwent catchment Jane Atkins recommended that should subsequent electrofishing show continued low densities, a survey of the invertebrate fauna should be undertaken to assess the food availability for salmonids, in order that lack of food could be ruled out as a contributory factor in their poor breeding success. Additionally the survey looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

Whilst the main River Derwent is quite a high profile salmon fishery, Trout Beck is not a significant fishery in its own right, but serves to maintain the genetic integrity of the wild populations of trout and salmon in the catchment by providing a unique habitat. This survey addressed the invertebrate food availability, and additionally looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

    Description: KurzfassungZahlreiche Fischereierzeugnisse aus dem Deutschen Handel wurden auf ihren Gehalt an Cholesterol hin analysiert. ZurAnalyse gelangten 38 verschiedene Dauerkonserven von acht Fischarten, 4 Produkte kalt geräucherter AtlantischerZuchtlachs in Scheiben, 10 Garnelenarten und 25 Fischstäbchenerzeugnisse von 5 Tierarten in Verbraucherpackungen. Bei den Dauerkonserven lagen die Gehalte zwischen 24 und 40 mg/100 g. Zwei Ausnahmen bildeten Sprottenkonserven mit durchschnittlich 107 mg/100 g und Oktopuskonserven mit 196 mg/100 g. Die Garnelenarten variierten zwischen 84 und 161 mg/100g. Die kalt geräucherten Lachsscheiben wiesen nur eine kleine Bandbreite im Cholesterolgehalt zwischen 38 und 43mg/100 g auf. Alle Fischstäbchen aus Magerfischen enthielten niedrige Gehalte an Cholesterol (Pangasius hypophthalmus 25, Seehecht 19, Seelachs 31 und Alaska Seehecht 28 mg/100 g), während die zwei Proben aus Tintenfischen über 100 mg/100 g lagen.AbstractNumerous fishery products from the German market have been analysed for their content of cholesterol. In total 38 different canned fishery products produced from 8 species, 4 products of sliced cold smoked Atlantic salmon, 10 species of crustacean shellfish and 25 different brands of consumer packages of fish fingers (produced from 5 species) were investigated. Canned fishery products contained amounts of cholesterol ranging from 24 to 40 mg/100 g. However, canned sprats exhibit cholesterol content as high as 107 mg/100g and canned octopus 196 mg/100 g. Crustacean shellfish was found to contain cholesterol content between 84 and 161 mg/100 g depending of species. Sliced cold smoked salmon in 200 g consumer packages showed only a little variation in cholesterol content (38-43 mg/100 g). In all fish fingers produced from lean fish species lowcholesterol content (pangasius or sutchi catfish 25, hake 19, saithe 31, and Alaska Pollack 28 mg/100 g, respectively) was found, whereas two products produced from squid exceeded 100 mg/100 g.

    Description: This is the Biological survey of River Teign and tributaries with references to the discharge of ball clay wastes, document produced by South West Water Authority in 1973. This report focuses on on-site assessment of the benthic macro-invertebrates of the lower River Teign, River Bovey, Ugbrooke Stream and Blatchford Brook was undertaken on 19th and 22nd August 1977 to assess the effects of discharges from ball clay mining premises. Inspection of aquatic fauna in the field is of necessity, less extensive than laboratory identification of sorted samples, so that the resulting data underestimates the water quality. This is more pronounced in the Chandler Score than in the Trent Biotic Index which does not take account of species abundance. Chandler should thus be interpreted by the trends described rather than by absolute values calculated.

    Description: The British Glossomatidae contains seven species, split between the genera Glossosoma, Agapetus and Synagapetus. One species, Glossosoma intermediumhas not been recorded in England since 2003. This was found in a side stream of Hayeswater gill in the Lake District. The main purpose of this survey was to try and locate and record Glossosoma intermedium and was a follow up to a similar survey we carried out in the Glennshee area of Scotland during April 2011. Additionally, as in the 2011 survey it also made sense that while looking for the larvae, pupae and adults of Glossosoma intermediumwe could also record other species of caddisfly (Trichoptera), mayfly (Ephemeroptera) and stonefly (Plecoptera).

    Description: This is the Coleopteran Fauna of ERS on the river Dane, Cheshire: a survey report produced by the Environment Agency in 2003. A comprehensive survey of the Exposed Riverine Sediment (ERS) on the River Dane, Cheshire was undertaken between mid-April and mid-June 2003. 6 locations were selected and subsequently examined to determine the importance of the constituent invertebrate fauna. Appropriate sampling techniques (i.e. pitfall trapping, hand searching and excavations) were directed towards the target group (Coleoptera). All adults from the chosen taxa were identified to species level. The relative value of the fauna was assessed using species richness, conservation status, fidelity score and a site quality index.

    Description: This is the Visual survey ERS Dane, Weaver & Bollin Catchments produced by the Environment Agency in 2005. Visual surveys of the River Dane downstream of the confluence with the Swettenham Brook, the River Weaver, and the River Bollin catchment in the EA Northwest South area of England were undertaken between 3rd and 9th February 2005 with the aim of identifying the spatial distribution and relative quality of exposed Riverine sediments (ERS). The potential value of these ERS in terms of likely habitat quality for ERS invertebrate communities was determined by recording a suite of appropriate environmental variables. Following an initial cartographical analysis of reaches likely to contain ERS, tens of kilometres of riverbank were inspected and 67 areas of ERS were selected for detailed visual survey. Site characteristics ranged widely both between and within catchments, with habitat quality ranging from poor to very high.

    Description: This is the River Leith fluvial audit: Final project report produced by Lancaster University in 1998. Freeze cores extracted from the upper and lower ends of River Leith illustrate that the bed is highly compacted in the downstream reach. Fine material is locally derived from bedrock at depths of only 32 cms into the bed and in one core fine material is 66% of the extracted core. Levels of fines that are believed to be detrimental to fish are put at 20 to 30%. Reduced flow and stream power from water abstraction may lead to a greater infiltration of fine material if gravels are not regularly flushed through with flood flows. Infiltration of fine material can lead to river bed compaction and concretion. A small abstraction may have no effect on the morphology of a river if the reduced discharge is within the normal range of flows experienced. However if the impact on flows is small it is still possible that fine sediment problems will develop progressively and the effects may not be noticed for several years.

This survey was carried out on the Kent Estuary on the 8th July, 1980 during the period 3h hours before to 1.5 hours after low water. The chemical water quality in the vicinity of Arnside was found, in general, to be good. The E. coli counts were found to be at or below the E E C mandatory value for bathing waters. Downstream of the Arnside outfall the E coli counts were generally above the E E C mandatory value, the counts getting higher at and after low water. B O D values also increased at low water though ammonia and phosphate (except for 1 sample) concentrations were low. The total coliform counts both at Arnside and below the outfall were always above the E E C mandatory level (except for 2 samples).

Surveys were carried, out on the Rivers Wolf, Thrushel, Lew and Lumburn, which are likely to be affected directly and indirectly by the construction and use of Roadford Reservoir. Of the upper reaches of three rivers to be affected directly by water releases, two were found to support abundant stocks of salmon and trout, and the third was found to contain abundant stocks of trout and eels. The River Thrushel will be affected indirectly and in this river salmon and trout stocks were present in slightly lower abundance than in others. Population estimates, densities, mean lengths and approximate biomass values were calculated. Other species were present in all rivers, usually in great abundance.

The upper reaches of the River Taw were severely polluted in October 1975 and there was widespread fish mortality. A survey was carried out to assess the recovery of salmonid stocks in the affected areas. Salmon showed a rapid recovery and trout have also recovered well. Both species have been assisted by widespread stocking. Several other species were present. Salmonid and total fish biomass was high. Further stocking of salmon is not recommended and it is also suggested that stocking with trout should be discontinued.

    Description: To ensure the authentication of fishery products lacking biological characters, rapid species identification methods are required. Two DNA- and protein-based methods, PCR-SSCP (polymerase chain reaction - single strand conformation polymorphism) of a 464 bp segment of the cytochrome b – gene and isoelectric focusing (IEF) of water-soluble proteins from fish fillets, were applied to identify fillets of (sub-) tropical fish species available on the European market. Among the samples analysed weretwo taxonomically identified species from the family Sciaenidae and one from Sphyraenidae. By comparison of DNA- and protein patterns of different samples, information about intra-species variability of patterns,and homogeneity of batches (e.g. fillet blocks or bags) can be obtained. PCR-SSCP and IEF may be useful for pre-checking of a large number of samples by food control laboratories.ZusammenfassungZur Sicherstellung der Authentizität von Fischerei-Erzeugnissen ohne biologische Merkmale sind schnelle Verfahren zur Speziesidentifizierung hilfreich. Zwei Methoden der DNA- bzw. Protein-Analyse wurden eingesetzt, um Filets (sub-) tropischer Fischarten, die auf dem europäischen Markt angeboten werden, zu identifizieren. Bei diesen Methoden handelt es sich um die PCR-SSCP (Polymerase-Kettenreaktion – Einzelstrang-Konformationspolymorphismus) – Analyse der PCR-Produkte und die IEF (isoelektrische Fokussierung) der wasserlöslichen Fischmuskelproteine. Unter den untersuchten Proben waren zwei taxonomisch bestimmte Arten aus der Familie Sciaenidae und eine Spezies aus der Familie Sphyraenidae. Durch Vergleich der DNA- bzw. Proteinmuster lassen sich Informationen über die intra-spezifische Variabilität solcher Muster und die Einheitlichkeit von Partien (beispielsweise Filetblöcke oder Filetbeutel) gewinnen. PCR-SSCP und IEF könnenin Laboratorien der Lebensmittelüberwachung als Vortest gerade bei hohen Probenzahlen sinnvoll eingesetzt werden.

    The role of substrate, flow and larval supply to recruitment of the red abalone (Haliotis rufescens) (2021)

    Description: Precipitous declines in wild populations of the red abalone Haliotis rufescens and the eventual closure of the commercial and southern recreational fishery have led to renewed interest in supplementing wild stocks with hatchery-raised individuals. Most work to date has focused on releasing small juveniles and has had limited success. Although much is known about larval settlement, juvenile survivorship and growth of abalone, there is scanty information on natural processes in the field. The failure of many regulated fisheries worldwide suggests that both the larval and juvenile stages may be important in determining the future population, and that early juvenile mortality is more important than previously believed. This paper presents a series of experiments designed to examine factors and mechanisms that could affect settlement, survivorship, and growth of larvae and early post-settlers in the field.Laboratory trials under different flow regimes showed that red abalone larvae settled preferentially on substrates encrusted with coralline algae, and that settlement was rapid when exposed to crusts compared to other surfaces. Urchin grazing of films appeared to facilitate abalone settlement but only when urchins were removed. Initial field experiments showed that released larvae settled on natural cobble rock, and that settlement was at least one order of magnitude greater when settlement habitats were tented. I then examined post-settlement survivorship at one and two days after settlement, and found that although there was a large amount of variation, on average 10% of released larvae were found as newly-settled recruits after 1 day. Survivorship and growth of recruits were followed over at least one month in both Spring and Fall. Abalone settled at higher densities, survived better and grew faster in the warmer Fall months than in the Spring. The density of month-old abalone recruits was correlated with density of naturally-occurring gastropods in the Spring, but not in the Fall. These results suggest that settlement and survivorship can be extremely variable across space and time, and that oceanographic and local biotic conditions play a role and should be considered when planning larval seeding.

    Description: This workshop was convened to begin building a foundation of understanding for developing and evaluating proposed measures for the rational management of the blue crab fishery in Chesapeake Bay. Our goal was to generate a summary of knowledge of blue crab stock dynamics. Specifically, we intended to address, and hoped to estimate, the basic parameters of an exploited stock - growth, mortality, natality, migration rates, sex ratios and abundance. In one sense these objectives were simply a means for organizing our discussions. A second objective was to compile at the workshop pertinent data held by the major research institutions on Chesapeake Bay so all participants could see the kinds and extent of existing data. As with many stock assessment problems, tailoring an estimating procedure around known existing data can be more productive than deciding on a procedure and then trying to find the required data in someone else's files.Authors of papers contributed to the report: B.S. Hester and P.R. Mundy (p. 50); Qisheng Tang (p. 86); L. Eugene Cronin (p. 111); J.R. McConaugha (p. 128); Cluney Stagg and Phil Jones (p. 153).

    Description: Organisms were collected on test panels, six inch lengths of dressed two by four inch pine, suspended in the water in a vertical position as described by Turner (1947). The panels were usually located at some convenient structure such as a dock-piling or sea-wall. Except where otherwise indicated by the data, the samples were collected from each station once a month between May 1950 and May 1953. During the three year period, seven hundred and nineteen panels were submerged in Chesapeake Bay. Approximately 14,000 organisms were encountered on these panels of which 20% or approximately 3,000 organisms could be identified from the dried pallets. Preliminary notes on the extent of fouling were made in the field after which the samples were removed to the laboratory for further study.

    Description: This paper is based on an attempt to assemble the existing knowledge of the silverside, Menidia menidia, and to contribute to what is known about the life history of this species. A vast amount of work is needed on the ecological relationships between the food fish and the forage fish. One of the most important forage fishes on the Atlantic Coast is the silverside. To understand the inter-relationships between the food fish and the forage fish it is necessary first to understand the life histories of both. For this reason it is important that the life history of this species be studied.

    Description: The determination of the distribution and seasonal fluctuations of ostracodes living in the littoral zone directly in front of the Chesapeake Biological Laboratory has been attempted in the present study. Samples taken in other parts of the Chesapeake Bay and around Solomons harbor, show that other species of ostracodes exist but these forms have not been considered in the two-year study here reported. The seasonal distribution of the species was compared with hydrographical records furnished for the same period by the Chesapeake Biological Laboratory in order to determine the correlation between ecological factors and seasonal fluctuations in numbers and species of Ostracoda.

    Economic analysis of climate change adaptation strategies in selected coastal areas in Indonesia, Philippines and Vietnam (2021)

    Description: Climate change with its attendant geophysical hazards is well studied. A great deal of attention has gone into analyzing climate change impacts as well as searching out possible mitigating adaptive strategies. These matters are very real concerns, especially for coastal communities. Such communities are often the most vulnerable to climate change, since their citizens frequently live in abject poverty and have limited capacity to adapt to geophysical hazards. Their situation is further complicated by the prospect of dealing with a confluence of hazards in comparison with those in other ecosystems. Against this backdrop Worldfish and the Economy and Environment Program for Southeast Asia (EEPSEA) collaborated to implement the cross-country study “Climate Change Impacts, Vulnerability Assessments, Economic and Policy Analysis of Adaptation Strategies in Selected Coastal Areas in Indonesia, Philippines, and Vietnam”. As its title suggests the study covered selected sites in Vietnam, Indonesia and the Philippines. Employing a gamut of interdisciplinary methodologies -- ranging from community-based approaches such as community hazard mapping and focus group discussions (FGDs) to regression techniques -- the study documented the impacts from three climate hazards affecting coastal communities. These were typhoon/flooding, coastal erosion, and saltwater intrusion. The team also analyzed planned adaptation options suited to implementation by communities and local governments, augmenting autonomous responses of households to protect and insure themselves from these hazards.

    Description: This guide was developed to document the process and activities that WorldFish staff have used and adapted as facilitators working with communities interested in marine resource management in Solomon Islands. It draws on the experiences from work conducted with FSPI and MFMR through ACIAR funded projects, with communities that had a primary interest in the management of coral reef fisheries. Since 2011 the process has been trialed and adapted further with communities interested in mangrove ecosystem management (through the MESCAL project). This guide is based on lessons about the process of a community developing, writing and implementing a management plan. This guide does not cover lessons about the outcomes of that management.

    Description: The Barotse floodplain is an ecosystem characterized by a paradox of widespread poverty amidst high ecological and agricultural potential. The CGIAR Research Program on Aquatic Agricultural Systems (AAS) seeks to address this paradox on the assumption that the rural poor have the potential to transform their lives using the aquatic resources in their environment. Understanding the conditions for natural resources use and management is critical for a program that seeks to transform the livelihoods of households dependent on natural resources. The purpose of this report is to identify and analyze key governance variables influencing the livelihood outcomes of AAS program interventions in the Barotse floodplain system.

    Description: Reports of high mortality resulting from the impoundment of crabs (Callinectes sapidus) during the preshedding period, to produce soft crabs, have been current in Maryland and Virginia for many years. The death rate of crabs on floats has been estimated by certain of the operators to run as high as 86% at Cape Charles, and to figures nearly as high at Crisfield and elsewhere during one season of the year. A study of this mortality and the factors influencing it have been in progress at the Chesapeake Biological Laboratory for two seasons.

    Description: The fouling community, its planktonic larvae and its predators were studied at Buccanneer Field, Texas from May, 1976 to April, 1977. Sixteen algae and 101 invertebrate species were identified from the structures. The existing fouling community was dominated by the large barnacle Balanus tintinnabulum, which provided a matrix of crevices in which other invertebrates were found. Unoccupied space was rare in the natural community but persisted for several months in disturbed quadrats, especially in winter. The erect bryozoan Savignyella lafonti and the urchin Arbacia punctulata were seasonally common on the well jacket but absent or rare on the production platform. On the other hand, the erect bryozoans Bugula neritina and Bugula rylandi and the hydroid Tubularia crocea were seasonally common on the platform but rate on the well jacket. Predator exclusion cages on experimental quadrats seemed to encourage the development of Savignyella lafonti and tubes of the corophiid amphipod Erichthonius brasiliensis. Scraped quadrats were recolonized primarily by hydroids, green algae and sponges. Several fouling species were found on shells on the bottom directly beneath the structures which did not occur on the structures themselves. Growth rates of several mollusks (Pteria colymbus, Musculus lateralis, Anadara transversa, Aequipecten gibbus, and Ostrea equestris) were sufficiently rapid to permit adult size to be attained in less than one year.

    Description: A new species of polychaete annelid, Nereis (Neanthes) micromma, is described and illustrated. The species, which is most abundant on muddy sand bottoms, has been collected offshore from the Texas coast. The inappropriateness of biarticulate in describing the palps of some nereidids is discussed.

    Description: Oyster (Crassostrea virginica) studies showed death rates to be low in Aransas and Galveston Bays but relatively high in Matagorda Bay. Initial mortality in Matagorda Bay was associated with freshwater and siltation but subsequent summer deaths were associated with Labyrinthomyxa infection.

    Description: Tissue samples analyzed indicate that residues of some pesticides are present in all Texas bay areas sampled, including Galveston Bay. The residues detected are DDT, Dieldrin and Endrin. The incident of DDT residues decreased slightly in both oyster, Crassostrea virginica, and fish samples during the study period. The incidence of Dieldrin increased dramatically in oyster samples while decreasing in fish samples. The incidence of Endrin remained essentially unchanged. Ovaries of speckled trout, Cynoscion nebulosus, contained enough DDT residue to cause concern over the possible impairment of reproductive ability.
