    Decomposition of diatoms and nutrient dynamics in permeable North Sea sediments (2004)
    In:  EPIC3Continental Shelf Research, 24(6), pp. 721-737, ISSN: 02784343
    Details
    Publikationsdatum: 2017-03-06
    Beschreibung: This study addresses the decomposition of diatoms in different permeable North Sea sand beds. During three cruises in 2001 to the southern German Bight, the regeneration of nutrients was assessed after the experimental deposition of organic matter corresponding to a typical spring diatom bloom in in situ and on-board chamber experiments. The diatom pulse was followed by a high regeneration of nutrients during the first day: 5–10% d−1 of the added nitrogen was converted to NH4+ and up to 0.67% d−1 of the added biogenic silica was dissolved to Si(OH)4. These results are used to interpret the response of pore water nutrient concentrations in permeable North Sea sands to seasonal nutrient and phytoplankton dynamics in the water column. The rapid advective solute exchange in these permeable sediments reduces the accumulation of regenerated nutrients, and, thus pore water concentrations of Si(OH)4, PO43− and NH4+ decreased with increasing permeability. All sands were characterized by relatively high NO3− concentrations down to 10 cm sediment depth, indicating that the upper sediment layers are oxidized by advective flushing of the bed. Our results demonstrate that biogenic silica and organic matter are rapidly degraded in permeable coastal sands, revealing that these sediments are very active sites of nutrient recycling.

    A scanning electron microscopic study of the seed coat structure of Curtia Chamisso & Schlechtendahl and Hockinia Gardner (Gentianaceae) (1983)
    In:  Miscellaneous publications of the University of Utrecht Herbarium (1572-6592) vol.1 (1983) nr.1 p.33
    Details
    Publikationsdatum: 2015-05-08
    Beschreibung: The six species of Curtia, including a hitherto undescribed species published here, as well as the monotypic genus Hockinia can be distinguished from each other by the seed coat structure. The anticlinal walls and the cuticle provide the most useful information. Curtia tenuifolia appears to be a complex species, but subsp. tenella can be readily separated from this complex by the seed coat structure. Heterostyly has been found in C. tenuifolia subsp. tenuifolia, C. obtusifolia, and Hockinia montana, but differences in seed coat structure can not be correlated with long-, short-, and equal-styled flowers. The differences in seed coat structure, the length of the seeds, and the number of cells per seed plead for maintaining Hockinia (closely related to Curtia) as a distinct genus. One new species of Curtia is described and a new combination is made.

    Beschreibung: SETTEN, A. K. van & KOEK-NOORMAN, J.: Studies in Annonaceae. VI. A leafanatomical survey of genera of Annonaceae in the Neotropics. — Bot. Jahrb. Syst. 108: 17—50. 1986. — ISSN 0006-8152. Within the scope of the multidisciplinary research project on systematics of Annonaceae, a survey of the leafanatomical features and their distribution in the neotropical Annonaceae is presented. The studied specimens form a rather homogeneous group, as may appear from the family description given here. A detailed study of the leafanatomical features reveals, that differences are mainly found in the indument, the position and contents of the idioblasts, the structure of the primary vein, the type of crystals in the epidermal cells, and the type of sclereids. Based on character states, phenetic similarities and differences are discussed and compared with the classifications of FRIES (1959) and WALKER (1971).

    Project Systematics of Annonaceae (1983)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.516 (1983) nr.1 p.1
    Details
    Publikationsdatum: 2015-05-08
    Beschreibung: Recently a multidisciplinary investigation program on the systematics of Annonaceae was started at Utrecht with special emphasis on the Neotropics. This project will be carried out largely within the framework of the UNESCO-project Flora Neotronica. The first goal is to provide a modern classification of the family as a whole, the second is the publication of a series of monographs for Flora Neotropica. The project has been planned and started in close consultation with leading botanists on the Neotropical flora. The Annonaceae are a family of pantropical distribution with between 2000 and 2500 species in ca. 130 genera as presently understood. In the Neotropics the family is represented by ca. 750 species and 35 genera. It is a family of trees, shrubs, and lianas. Its place is within the order of the Magnoliales and its supposedly closest relative is the family of the Myristicaceae. The Annonaceae, although generally considered primitive in many features, nevertheless offer a number of specialized features as well This makes it a promising object using various kinds of comparative morphological, karyological, and anatomical data. Besides, many species are of medicinal or commercial value, such as various species of Annona and Rollinia, the fruits of which are commonly eaten in most countries of Central America and South America; the Soursop (Annona muricata) is widely cultivated throughout the tropics.

    Beschreibung: In his introductory statements to 'The Symposium on the Phylogeny and Classification of the Filicopsida' which was held in London, 1972, HOLTTUM, when dealing with 'dubious groups of relationships which would particularly repay investigation', mentioned the Polypodiaceae first (HOLTTUM, 1973: 6). Talking about Polypodiaceae the present authors deal with the Polypodiaceae sensu stricto only, thus excluding the Cheiropleuriaceae, Dipteridaceae, Grammitidaceae, and also the Loxogrammaceae, taxa which were formerly (or are still) included in the Polypodiaceae sensu lato. As delineated in this way, this almost exclusively pantropical family consists of about 600 species and an indefinite number of genera.

    Beschreibung: The Tenasserim lutung Trachypithecus barbei was previously known from museum specimens and field observations only. We discovered a zoo specimen and present the first confirmed evidence for the continued existence of the species since 1967. We describe the cranial pelage and coloration characteristics of this species which were previously unknown. We present first molecular evidence for recognizing T. barbei as a distinct species and for assessing its phylogenetic affinities relative to other members of the genus Trachypithecus. We document the taxonomic history of T. barbei and present a distribution map based on a compilation of all known locality records.

    Quantitative morphological variation in Sagitta setosa Müller, 1847 (Chaetognatha) and two closely related taxa (2004)
    In:  Contributions to Zoology (1383-4517) vol.73 (2004) nr.4 p.305
    Details
    Publikationsdatum: 2015-05-08
    Beschreibung: This paper reviews the quantitative morphological variation published for Sagitta setosa Müller, 1847 and two other species described within the S. serosa-complex, viz., S. euxina Moltschanoff, 1909 from the Black Sea, and S. batava Biersteker & Van der Spoel, 1966 from the Scheldt Estuary (Netherlands). Data on total (body) length, caudal length, numbers of teeth and hooks, ovary length, and dimensions of fins are compared between these three taxa. Additionally, samples from the North Sea, Mediterranean, and Black Sea are compared to look for geographic differences. Specimens from the Mediterranean were smallest with relatively long caudal segments, and few teeth and hooks, whereas specimens from the Black Sea were largest with relatively short caudal segments and many teeth and hooks. Specimens from the North Sea were intermediate with regards to these characters, but ranges overlapped and there were no obvious differences in allometry. These differences may be ecophenotypic, as the warm and salty Mediterranean Sea and cool and brackish Black Sea are at opposite ends of the environmental spectrum. The dimensions related to the fins showed clearer distinction between samples from different geographical areas, and slight differences in allometry. However, few data were available and little is known about the variance within each geographical area. We found more variation in quantitative characters within S. setosa from different parts of its range than between S. setosa and either S. hatava, or S. euxina. Sagitta batava conformed to S. setosa in terms of all the morphological characters considered. The data for S. setosa derived from Biersteker & Van der Spoel (1966) were atypical and were found to be based on misidentifications of S. elegans. Therefore, we concluded that S. batava cannot be considered a separate taxon. For S. euxina, the data were inconclusive. Quantitative data completely overlapped between S. setosa from the Black Sea and S. euxina, but few data of S. setosa from the Black Sea were available. Because samples were either composed entirely of S. setosa or S. euxina (depending on sampling season and depth) and there was a large variation in body lengths and relative ovary lengths, we consider it possible that these samples represent seasonal variants of one and the same species.

One would have thought that in this age of the internet one would be turning to convenient web-sites to find the latest catalogues of data and information about biodiversity of animal groups. Indeed, such do exist, and many of them are remarkably detailed and informative. Nevertheless, there has been a steady stream lately of traditional hardcopy volumes presenting systematic and taxonomic overviews of various groups of animals. This handsome two-volume set is amongst the latest example of these kinds of books to appear.

    Community composition and species richness of parasitoids infesting Yponomeuta species in the Netherlands (2004)
    In:  Contributions to Zoology (1383-4517) vol.73 (2004) nr.4 p.255
    Details
    Publikationsdatum: 2015-05-08
    Beschreibung: Parasitoid assemblages infesting Yponomeuta species in the Netherlands were investigated. Parasitoid species richness and community composition were related to host species, habitat, temporal and spatial variation. Both community structure and species richness did not differ among habitats. There was no significant difference in species richness between years (1994 and 1995) but there was a significant difference in community composition. Community composition and species richness both differed among host species, although this latter result was solely due to the host species Y. evonymellus. There was no significant relationship between community similarity and distance. These results indicate that the parasitoids of the moth genus Yponomeuta in the Netherlands appear to form a spatially stable, but temporally variable community. Most of the variation in community structure was, however, related to the host species. The marked difference in parasitoid species richness and community composition of Y. evonymellus when compared to the other species warrants further study.

    Carcinization in the Anomura – fact or fiction? II. Evidence from larval, megalopal and early juvenile morphology (2004)
    In:  Contributions to Zoology (1383-4517) vol.73 (2004) nr.3 p.165
    Details
    Publikationsdatum: 2015-05-08
    Beschreibung: In this second of a two-part series, carcinization in the Anomura has been reviewed from early juvenile, megalopal, and larval perspectives. Data from megalopal and early juvenile development in ten genera of the Lithodidae have provided unequivocal evidence that earlier hypotheses regarding evolution of the king crab pleon were erroneous. A pattern of sundering, and decalcification has been traced from the megalopal stage through several early crabs stages in species of Lithodes and Paralomis, with supplemental evidence from species in eight other genera. Of major significance has been the attention directed to the marginal plates of the second pleomere, which when separated in lithodids are not homologous with the adult so-called “marginal plates” of the following three tergites. Auxiliary megalopal and early juvenile lithodid data, as well as equivalent data from other paguroids, support the evolutionary direction indicated by lithodid pleonal plate development. Therefore, while carcinization, or development of a crab-like body form, has occurred in the Lithodidae, it has not proceeded from a hermit crab ancestor. Rather the data suggest the reverse, thus effectively refuting the “hermit to king” myth. Brief reviews of data available from the Lomisidae and Porcellanidae support the Proposition of independent anomuran carcinization events in these taxa as well. Results of cladistic analysis of megalopal and juvenile data, although somewhat unconventional, do not support the claim of a sister-group relation of the lithodid genera Lithodes and Paralithodes with the pagurid genus Pagurus. Attempts to subject larval phase data to similar analysis were thwarted by the tendency in paguroids, including lithodids, for lecithotrophic development. Additionally, presumed initial and terminal stage deletions disallow the ontogenetic stage homologies required for meaningful phylogenetic results.

    Short notes and reviews Bidder’s organ in the female of Bufo ictericus: morphological characterization (2004)
    In:  Contributions to Zoology (1383-4517) vol.73 (2004) nr.4 p.317

    Publikationsdatum: 2015-05-08
    Beschreibung: Bidder’s organ has been cited as a structure present only in males of the toad family Bufonidae, and is used as a systematic characteristic. In this study, we examined females of Bufo ictericus in order to ascertain whether this structure also occurs in females. Macroscopic observations and light microscopy technique for paraffin embedding were performed. This study reveals that females of Bufo ictericus can have a Bidder’s organ with typical morphology, and in close spatial relationship with the ovary. This suggests that the Bidder’s organ is not an exclusive structure for male toads, but that it may also occur in active females.

    Beschreibung: IUCN, says the paper Categories, Objectives and Criteria for Protected Areas, ”is dedicated to the wise use of the Earth’s natural resources and to the maintenance of the Planet’s natural diversity.” What to think of the sequence? Use first, maintain second? And this comes from the International Union for the Conservation of Nature and Natural Resources? ”The World National Parks Congress, taking place in Bali, Indonesia, October 11-22, 1982, will provide case studies from around the world to illustrate how the various categories of protected areas are meeting the needs of countries of all economic, social, cultural, and political backgrounds,” writes J.A. McNeely, the secretary of the Commission on National Parks and Protected Areas, in a special issue of the Swedish journal Ambio (11: 237. 1982). ”No longer just playgrounds for vacationers and means for conserving natural heritage, protected areas have become an inseparable part of the modern human ecosystem.”

    Beschreibung: Tropical Botany in Aberdeen University. This was started by Professor J.W.H. Trail, who held the chair from 1877 to 1919, and travelled in the Amazon Valley (1873-75) mainly collecting cryptogams and studying palms. He was succeeded by Prof. W.G. Craib (1920-33) who was never in the tropics but devoted his work to the Flora of Siam, based on the collections of A.F.G. Kerr, and assisted by Miss E.C. Barnett. After a considerable lag, tropical botany was revived by the energetic efforts of Dr. P. Ashton as lecturer in systematics and ecology of the eastern tropics, establishing ties with Malayan colleges in teaching and research. This is at present perpetuated by two lecturers, Dr. K. Jong and Dr. M.D. Swaine, the latter’s experience lying largely in the tropics of West Africa. In addition Dr. N.M. Pritchard, Dr. J.B. Kenworthy and Dr. G. Hadley have been on secondment to the University of Malaya, while Dr. I. Alexander made research visits to India, Ghana and Peru. Over the years the Department has provided undergraduate and research training to innumerable students from many different tropical countries, some of which attained responsible posts, e.g. Prof. E. Soepadmo. Important courses in tropical biology are given, not available elsewhere in the U.K. (started 1973). The benefits for Aberdeen students is important: amongst others they led to expeditions to various parts of the tropics, recently to Sabah and to the Ivory Coast. Royal Society Tropical Rain Forest Collaborative Research Programme. Arising out of a feasibility study by Dr. T.C. Whitmore and P.F. Cockburn, the theme ’Recovery of tropical rain forest after disturbance’ was adopted as the initial basis of the programme. Possible territories for the research include Sabah and the Philippines. Detailed plans for a 5-year project are being prepared in consultation with colleagues in Southeast Asia.

    Beschreibung: It is with the utmost regret that we announce the sudden and quite unexpected death of Dr. Marius Jacobs, editor of this Bulletin. See the obituary on page 3869. He was co-editor of the Flora Malesiana Bulletin for nr. 17 (1962) to nr. 22 (1968) and took full responsibility onwards of nr. 27 (1974). He showed great ability in enlarging its scope and we have many letters in our archives expressing appreciation and admiration for the lively and informative style in which he edited the Bulletin. I had to take over the editorial work for this number at short notice, but I was greatly helped by a number of Rijksherbarium colleagues, which help is gratefully acknowledged. In this way the delay has been kept to a minimum. It is, however, possible that some news items etc. have not been printed and that information submitted to Dr. Jacobs has not been entered due to this sudden change of editorship. I offer my apologies if this has happened and hope that (if still relevant) the news will again be forwarded to the new editor, Dr. J.F. Veldkamp, Rijksherbarium, who will take over starting next number.

    Beschreibung: Three new species of the Southeast Asian orchid genus Dendrochilum Blume are described. All three seem to belong to the phenetically defined subgenus Platyclinis (Benth.) Pfitzer. As indicated by the name, D. celebesense H.A. Pedersen & Gravend. originates from Sulawesi. The geographic origins of D. coccineum H.A. Pedersen & Gravend. and D. warrenii H.A. Pedersen & Gravend., on the other hand, are unknown, but parsimony analyses of sequences of the plastid accD-psaI intergenic spacer and nuclear ribosomal ITS1-5.8S-ITS2 region and morphological affinities suggest they should both be counted as members of the Philippine flora.

    The ascidiform early development of free carpels, a S.E.M.-investigation (1983)

    Beschreibung: Carpels develop centripetally as oblique slightly ascidiform structures provided with a seat-like support. The terminal mouth of the ascidiform primordium becomes the lateral cleft of the carpel. Solitary terminal carpels develop as lateral structures. The sections Tasmannia and Drimys of the genus Drimys differ by the varying degree of ascidiform development. Austrobaileya is like Drimys. The structure of the carpel margins with submarginal placentation may have evolved from a slit like that in Winteraceae. Allometric development of an oblique ascidiform structure may have formed a large basal ovary, and may thus have moved the stigmatic part apically. A possible cupular origin of carpels is discussed.

    Beschreibung: The buthid scorpions of the genus Centruroides are widely distributed in the Antillean area. They are also the most common scorpions in the majority of these islands. Nevertheless they remained almost forgotten until recently (STAHNKE 1970; ARMAS 1976, 1977, 1980, 1981, 1982; FRANCKE & SISSOM 1980). For the purpose of this paper the Lesser Antilles are defined as the islands situated between the Virgin Islands and Trinidad & Tobago, according to BOND’S 1978 zoogeographical point of view.

    The Upper Devonian deposits in the northern part of Leon (Cantabrian Mountains, Northwestern Spain) (1983)
    In:  Leidse Geologische Mededelingen (0075-8639) vol.52 (1983) nr.2 p.179

    Publikationsdatum: 2014-10-27
    Beschreibung: During the Late Devonian, deposition in the Cantabrian Mountains was largely controlled by movements along faults. By way of intermitting subsidence of the area south of the Sabero-Gordón line and the connected progradation of the coast during the Frasnian and early Famennian, three regressive sequences were deposited. On account of these sequences the Nocedo Formation is divided into three units. Before the late Famennian transgression, after which the upper part of the Ermita Formation was deposited, the area was peneplained. Six facies maps show the changes in palaeogeography during the Late Devonian.

    The geology of the region to the southeast of Lugo (N.W. Spain) (1983)
    In:  Leidse Geologische Mededelingen (0075-8639) vol.52 (1983) nr.3 p.513
    Details
    Publikationsdatum: 2014-10-27
    Beschreibung: The area described comprises the SE plunging extension of the anticlinorium of Mondoñedo-Lugo-Sarria and several structural units to the NE of it. The stratigraphy compares with that of neighbouring areas. Certain new observations have been made regarding the west flank of the East Galician-West Asturian miogeosyncline at the end of the Precambrium and during the Early Palaeozoic. Stromatolites or algae played an important part in the formation of carbonate deposits during late Precambrian (Cándana limestone) and Lower Cambrian time (Vegadeo limestone). An imprint, possibly attributable to a specimen belonging to the Precambrian Ediacara fauna, was found in the Cándana Schist Formation. A shallow or relatively high zone existed during that time in the region around Incio. The same general area formed a high again at the end of the Ordovician, causing erosion and a marked disconformity of the Silurian. The Hercynian structures can be explained by assuming roughly WSW-ENE compression and shortening. In the NW of the area this is expressed in the first place by the recumbent folds of the Lugo-Sarria anticlinorium, and in the SE by the narrowness of the steep folds and their slightly changed direction in the general area of Seoane and El Cebrero. Normal crossfaults are related to the folding and the compression. They show locally a deviation in accordance with the direction of shear stress. Horizontal displacement along such faults in an EW direction was probably of little importance. Finally a few observations are given on the occurrence of Pb-Zn ores at the mine of Rubiales.

    Distribution and variation of Carinariidae and Pterotracheidae (Heteropoda, Gastropoda) of the Amsterdam Mid North Atlantic Plankton Expedition 1980 (1983)
    In:  Beaufortia (0067-4745) vol.33 (1983) nr.6 p.73
    Details
    Publikationsdatum: 2014-10-27
    Beschreibung: Species of the heteropod families Carinariidae and Pterotracheidae collected in the Mid North Atlantic Ocean in 1980 have been studied. The distribution of the species is given, as well as the morphological variation. It is concluded that two subspecies of Carinaria lamarcki actually have to be considered distinctly recognisable and sympatric species, to be called C. lamarcki and C. challengeri. The vertical distribution of the heteropods studied proves not to be restricted to the photic zone and diurnal vertical migration occurs among the larger species. The horizontal distribution of the two Carinaria species and of at least two populations of the Pterotrachea species coincides with the southern branch of the North Atlantic Current, while others are restricted to the subtropical waters. Consequently, the present heteropods have to be considered good indicators of water masses and currents.

    An unusual new gorgonian coral (Anthozoa: Octocorallia) from the Aleutian Islands, Alaska (2004)
    In:  Zoologische Mededelingen (00240672) vol.78, 1-16 (2004) p.265
    Details
    Publikationsdatum: 2007-01-18
    Beschreibung: Despite the abundance and ecological importance of octocorals in Alaskan waters, most of the species in this assemblage remain unidentified and/or undescribed. One of the largest and most abundant species from the Aleutian Islands found at depths ranging between 125 and 512 m is a new and very unusual gorgonian coral. It has stout upright colonies that are laterally branched, with thick, more or less clavate terminal branches. Its major distinguishing characteristic is its possession of tiny sclerites with stubby double heads, which occur in the outermost coenenchyme. Another significant character is its oval capstans with elaborate ornamentation. The gorgonian is described as Alaskagorgia aleutiana new genus and species (Cnidaria: Octocorallia: Holaxonia: Plexauridae). It is described and assigned to Plexauridae because of the affinity of DNA sequences (1337 bp mtDNA: ND2 and MSH1) of A. aleutiana with other plexaurid corals, even though the predominant coenenchymal sclerites are somewhat smaller and different than is usual in plexaurid genera.

    Soft-sediment ichnotaxa from the Cenozoic White Limestone Group, Jamaica, West Indies (2004)
    In:  Scripta Geologica (03757587) vol.127 (2004) p.341
    Details
    Publikationsdatum: 2007-01-19
    Beschreibung: Jamaica, the third largest of the Greater Antillean islands, exposes various lithological units that are dominated by Cenozoic carbonate rocks including those of the mid-Cenozoic White Limestone Group. This Group is comprised of six formations, the Troy, Swanswick, Somerset, Moneague, Montpelier and Pelleu Island formations. An uncommon but moderately diverse, poorly to moderately preserved softsediment ichnofauna is described herein from several of these, namely the Moneague, Montpelier and Pelleu Island formations, which have yielded 15 ichnogenera represented by 27 ichnospecies. These are: Bergaueria hemispherica? Crimes, Legg, Marcos & Arboleya; Chondrites furcatus Sternberg; Chondrites isp.; Circulichnus montanus Vialov; Dactyloidites ottoi (Geinitz); Dactyloidites peniculus D’Alessandro & Bromley; Diplocraterion isp. cf. D. parallelum Torell; Glockerichnus parvula (Ksia˛z · kiewicz); Helminthopsis hieroglyphica Wetzel & Bromley; Ophiomorpha nodosa Lundgren; Palaeophycus herberti (Saporta); Palaeophycus tubularis Hall; Palaeophycus isp.; Planolites beverleyensis (Billings); Planolites montanus Richter; Planolites isp.; Schaubcylindrichnus coronus Frey & Howard; Scolicia prisca Quatrefages; Scolicia strozzii Savi & Meneghini; Taenidium cameronensis (Brady); Taenidium serpentinum Heer; cf. Taenidium barretti (Bradshaw); Thalassinoides horizontalis Myrow; Thalassinoides paradoxicus (Woodward); Thalassinoides isp.; Trichichnus linearis Frey; and Trichichnus simplex Fillion & Pickerill. Various processes such as dolomitization, lack of bedding plane surfaces, lack of contrasting lithologies precluding toponomic preservation, case hardening and chertification may, individually or in combination, be responsible for the variable ichnofaunal diversity within and between the various formations of the White Limestone Group.

    Considerations on most Rugosa and the Dividocorallia from de Groot’s (1963) collection (2004)
    In:  Scripta Geologica (03757587) vol.127 (2004) p.71
    Details
    Publikationsdatum: 2007-01-19
    Beschreibung: Rugose corals reinvestigated herein constitute the main part of the collection described by de Groot (1963). The taxonomy proposed herein differs in several instances from that accepted originally by de Groot. Some changes, such as Petalaxis for Lithostrotionella and Calophyllum instead of Polycoelia, were already introduced in de Groot’s unpublished catalogue. Others were introduced in order to match the recent advances in rugose coral systematics. Most systematic changes were based on new microstructural, diagenetic and hystero-ontogenetic studies. These are described in detail for individual species and briefly discussed in the concluding considerations. Trabecular microstructure of septa and its diagenetic alteration was documented for most species. Presence of two kinds of intercorallite walls (partition and dividing walls) was documented on the basis of their difference in microstructure. This was especially important for the genus Petalaxis, allowing proof of a distinction between species representing its nominative subgenus and that distinguished by de Groot as Hillia. A new name Degrootia was proposed for Hillia, which is preoccupied by a lepidopteran. Two genera, one new (Arctocorallium gen. nov.), represented by two species, were transferred to the Calyxcorallia (Dividocorallia), the order and subclass not distinguished by de Groot. Both those species were investigated and documented in particular detail, especially their hystero-ontogeny. The restudied material allowed proof of a distinction between the Calyxcorallia and the Rugosa in the insertion of major septa. Also, an uncertain status of minor-like septa that may replace the major septa was demonstrated. Both those determinations are based on the hystero-ontogeny.

    Fish microfossils from Ramsåsa, site E, Scania, southern Sweden (mid Palaeozoic) (2004)
    In:  Scripta Geologica (03757587) vol.127 (2004) p.1
    Details
    Publikationsdatum: 2007-01-19
    Beschreibung: Material from three pieces of rock from Ramsåsa, site E, was divided into size fractions 0.106, 0.212, 0.355, 0.425 and 0.5 mm. Larger sizes were absent. The three assemblages were examined and compared with each other, also per fraction, and with residue samples from site E. The latter are proportionately not representative of the faunas of which they must have been part, specimens measuring 0.5 mm or more. The residue labels refer to Ørvig and his student Peyel. The results of the comparison between the assemblages from the rocks and from the residues are hardly complementary. Thelodont scales were obtained almost exclusively from the pieces of rock; acanthodian ‘modified trunk’ scales, spines and jawbones and rare birkeniid remains were restricted to the stored residues, which also yielded a variety of osteostracan (‘hemicyclaspid’ and ‘zenaspid’) armour fragments. A late Ludlow age (within the T. sculptilis biozone) is suggested for the rock samples on the basis of the fish assemblages alone. Since the Ørvig and Peyel residue materials contained T. sculptilis scales, they are not older than the T. sculptilis zone (Upper Ludlow- Lower Pridoli).

    On the Barremian-Early Albian biogeography (by ammonites) of Colombia (2004)

    Beschreibung: On the basis of new and published palaeontological and stratigraphical data, the qualitative and quantitative variations in the Barremian-early Albian ammonite fauna of Colombia have been documented and analyzed. The position adopted here is that in the early Barremian the Andean Province became replaced by the Caribbean Subprovince in Colombia. The Caribbean Subprovince became separated as an independent unit from the Andean Province on the generic level (Buergliceras, Pedioceras), but especially on the species level. In the middle/upper Aptian many new endemic genera and subgenera appeared; Juandurhamiceras, Neodeshayesites, Laqueoceras, Zambranoites, Riedelites and Pseudoptychoceras. Besides, many endemic middle Aptian species of other, non-endemic genera appeared. Beginning from the middle Aptian the Caribbean area was a separate biogeographic enitity with the rank of Province; the Colombian region is considered to be the core area of the Caribbean Province.

    Beschreibung: The genus Mama Belokobylskij, 2000 (Braconidae; Euphorinae) is re-assessed and the type species is compared with three similar species: Microctonus cephalicus Provancher, 1886, Microctonus reclinator Ruthe, 1856, and Euphorus spiniscapus Muesebeck, 1936. The results are discussed in relation to the use of taxa based on one specimen (“monotype taxa”). Problems concerning our knowledge of important groups of Euphorinae are outlined. The context of the peculiarly tangled taxonomical situation, which this paper deals with, is considered to be widespread in parasitoid taxonomy, and should be borne in mind in current studies of parasitoid biodiversity assessment.

    Comparative reproductive anatomy in the South African giant land snails (Gastropoda: Pulmonata: Achatinidae) (2004)

    Beschreibung: The history and current taxonomic status of 62 nominal taxa are revised that have been associated in the literature with the subgenus Tholachatina Bequaert, 1950, of genus Archachatina Albers, 1850, and the genus Cochlitoma Férussac, 1821, in the land snail family Achatinidae Swainson, 1840. Tangible, reliable characters have been found in the detailed features of the reproductive anatomy in this family. The results of comparative anatomical study convincingly reflect phylogeny in contrast to the comparative study of only the shell characters. This latter more strongly reflects the effects of the intrinsically variable environment over time. In the present study, both sets of characters are needed to refine identification. Change, and therefore speciation, is shown in the reproductive system through anatomical differences that may develop in the functional interrelationships of the two integral reproductive systems of hermaphroditism. Limited adjustment to anatomical change over time has established for each genus a typical, characteristic reproductive anatomical pattern or configuration. Because this pattern has a basically high degree of physical stability within a population, it becomes an identifying character for the genus, and more restrictedly so for the species. Two new genera (Bruggenina and Brownisca) and two new species (Cochlitoma kilburni and C. wigleyi) are described on the basis of distinctive anatomical characters. The genus Cochlitoma sensu Pilsbry (1904) is resurrected and redescribed. It contains most of the southern African achatinid species. Bequaert’s subgenus Tholachatina (1950) of West African genus Archachatina is invalid. The genus Archachatina Albers, 1850, has no endemic species in southern Africa.

    Re-description of Phymactis papillosa (Lesson, 1830) and Phymanthea pluvia (Drayton in Dana, 1846) (Cnidaria: Anthozoa), two common actiniid sea anemones from the south east Pacific with a discussion of related genera (2004)

    Beschreibung: Actiniid sea anemones possess few characteristics of taxonomic value, which makes columnar outgrowths one of the most important features for systematic work. There are two species of actiniid sea anemones known from Chile and southern Peru that exhibit a column densely covered with non-adhesive vesicles: Phymactis papillosa (Lesson, 1830) (= Phymactis clematis) and Phymanthea pluvia (Drayton in Dana, 1846). Hereby both are re-described in detail. The re-descriptions are based on observations of about 100 living animals in their habitat and in aquaria and on the examination of 21 specimens of P. papillosa and seven specimens of P. pluvia collected in Chile between 1995 and 2003. In Chile, specimens of both species occur in tide-pools, on vertical and overhanging rock-walls in the intertidal zone and in shallow water down to depths of 16 m. Large size, numerous short tentacles, and acrorhagi characterize both species. Phymactis papillosa is a widely distributed species: its occurrence is confirmed from Playa Tantalean, Peninsula Bayovar, Peru (05°48’15’’S, 81°04’99’’W), to the Archipelago de los Chonos (44°24’S; 73°34’W), south Chile, for the Gulf of California (24°08’N; 110°15’W) and for the Pacific coast of Mexico (23°26’N; 110°15’W) as well as for some Pacific Islands. Phymactis papillosa occurs solitarily and in clonal aggregations and exhibits four distinct colour varieties: var. rubra, var. viridis, var. cyanea and var. fusca as well as some mixed morphs. Phymanthea pluvia can be found between Caleta Yasila, Paita, Peru (05°07’38’’S, 81°10’07’’W), and the region of Valparaíso, central Chile (33°02’S, 71°38’W). Specimens of P. pluvia always have a hardly varying orange colour; the apexes of its vesicles are whitish. Morphologically both species are quite similar; besides the colour they can be distinguished by the histological structure of the vesicles and by the numerous rod-like basitrichs in the acrorhagi of P. papillosa. Structure and histology of the vesicles of both species are described in detail and possible functions and the taxonomic value of vesicles are discussed. The distinctive characters of the genera Phymactis Milne Edwards 1857, Bunodosoma Verrill, 1899, and Phymanthea Carlgren, 1959 are given. Valid as well as doubtful species of all three genera are listed.

    Moult cycle and morphogenesis in Hyas araneus larvae (Decapoda, Majidae), reared in the laboratory (1983)

    Details
    Publikationsdatum: 2019-07-17
    Beschreibung: Moult cycle and morphogenesis in larval instars (zoea I, zoea II, megalopa) of the spider crab Hyas araneus were studied in the laboratory. Changes in the epidermis and cuticle were documented photographically at daily intervals to characterize the stages of the moult cycle. Stage A (early postmoult) is a very short period during which the larva takes up water. During late postmoult (B) and intermoult (C) the endocuticle is secreted, and there is conspicuous epidermal tissue condensation and growth. The onset of early premoult (D sub(0)) is characterized by epidermal apolysis, occurring first at the bases of the setae in the telson of zoeal instars or in the rostrum of the megalopa.

    Changes in biomass and chemical composition of spider crab (Hyas araneus) larvae reared in the laboratory (1983)
    In:  EPIC3Marine Ecology Progress Series, 12, pp. 91-101
    Details
    Publikationsdatum: 2019-07-17
    Beschreibung: Larval and early post-larval growth has been investigated in H. araneus L. (Majidae) reared in the laboratory. Growth was measured as dry weight (DW), ash-free dry weight (AFDW), carbon (C), nitrogen (N), hydrogen (H), gross biochemical constituents (protein, lipid, carbohydrate, chitin, ash) and energy (calculated separately from carbon and biochemical composition). During larval development, i.e. from freshly hatched zoea-I to late megalopa, all these criteria of biomass increase by factors ranging between 5 and 14; carbohydrate shows the lowest, chitin the highest increment. There are indications of loss in organic body weight during the latest period preceding metamorphosis to the crab stage. When no food is offered during this time, megalopae lose significantly more biomass than control larvae. This suggests that food is still required, but feeding activity is reduced to a level below maintenance ingestion rate. Following metamorphosis, the juvenile crab accumulates biomass at a far higher absolute rate (expressed as µg/d) than all larval stages.

    Radionuclides as tracers for particle flux and transport of water masses in the Atlantic sector of the Southern Ocean (2004)

    Beschreibung: The natural uranium decay series provide a suite of tracers to study transport processes in the ocean. We have used nuclides of the particle-reactive elements Th, Pa, Pb and Po for studies of particle flux in the Southern Ocean, whereas isotopes of the elements Ra and Ac served as tracers for the transport of water masses. Here we summarize the specific aspects of the behaviour of these nuclides in the Southern Ocean and give some examples of their application. We review the important influence of exchange between ocean basins by advection and upwelling on the long-lived nuclides. We show how the distribution of 234Th in surface waters across the ACC represents the export production, whereas in the benthic nepheloid layer this tracer is used to illustrate how the resuspension regime in the ACC is linked to the position of the oceanographic fronts.

    Beschreibung: The development of hard bottom communities has been studied on test panels in Helgoland Harbour (German Bight) since 1977. Settlement and growth of epibenthic species was examined monthly. Natural variation in different seasons, years, and at three stations (the latter, only in 1981 and 1982) was investigated. At Station A (Binnenhafen), barnacles (Balanus crenatus ) and polychaetes (Polydora ciliata ) were always among the first settlers in spring. They were followed by other barnacles (Elminius modestus, Balanus improvisus ) and by colonical ascidians (Botryllus schlosseri ). The latter species often dominated from August to October, and tended to overgrow the barnacle populations.

    The adsorption of Thorium and Protactinium onto different particle types: Experimental Findings (2004)
    In:  EPIC3Geochimica et cosmochimica acta, 68(7), pp. 1489-1501, ISSN: 0016-7037
    Details
    Publikationsdatum: 2019-07-17
    Beschreibung: Here we present the results of experiments concerning the adsorption of Thorium (Th) and Protactinium (Pa) on different particle types. Particle types used were smectite (as a representative of clay), biogenic opal, CaCO3 and MnO2. Additionally one sample was run without particles added. Experiments were performed with recently sampled seawater from three regionally different locations, which had been 0.2 µm filtrated previous to our experiments. Herewith we made sure that the seawater kept its natural composition in dissolved organic matter (DOM), which has been shown to play an important role in the transfer of Th to the particulate phase.In the control run with no particles added, in all three cases a significant amount of Th was observed in the particulate phase. Obviously, spontaneously formed particles as described by Chin et al. (1998) were responsible for Th found in the particulate phase. The adsorption of Th on clay strongly resembled that of the spontaneously formed particles, but with increased adsorption efficiency. In agreement with observations from terrestrial systems, we conclude that clay minerals may serve as a carrier for organic carbon also in the ocean. The relationship between so-called mineral ballast and carbon export (Armstrong and Jahnke 2001) may be closely linked to this observation.The obtained Th/Pa fractionation factors are only for smectite and MnO2 quite constant. For smectite, in all three water types a fractionation factor of about 6 is obtained. For MnO2, the fractionation factor scatters around unity. On biogenic opal, mostly fractionation factors of about two to three were observed.Our results have large implications for the interpretation of Th and Pa data from natural samples. They show up differences in the scavenging behaviour of particles depending on the composition of seawater in the phase 〈0.2 µm, which varies with its provenance.

    Beschreibung: We tested the applicability of the carbon isotopic composition of C37:2 alkenones (delta13C37:2) as a proxy for dissolved carbon dioxide CO2(aq) in oceanic surface waters. For this purpose we determined delta13C37:2 in suspended particulate organic matter (POM) and surface sediments from the South Atlantic. In opposite of what would be expected from a diffusive CO2 uptake model for marine algae we observed a positive correlation between 1/[CO2(aq)] and the isotopic fractionation (epsilon p) calculated from delta13C37:2. This clearly demonstrates that CO2(aq) is not the primary factor controlling epsilon p at the sites studied. On the other hand we found a negative correlation between epsilon p and the phosphate concentration in the surface waters (0-10 m) supporting the assumption of Bidigare et al. (1997) that epsilon p is primarily related to nutrient-limited algal growth rather than to [CO2(aq)]. Reconstructing past CO2(aq) levels from delta13C37:2 thus requires additional proxy information in order to correct for the influence of haptophyte growth on the isotopic fractionation. In the eastern Angola Basin, we previously used delta15N of bulk organic matter as proxy for nutrient-limited growth rates. As an alternative the Sr/Ca ratio of coccoliths has been recently suggested as growth-rate proxy which should be tested in future studies.

    Derivation of dissolved organic carbon concentrations from SeaWiFS data (2004)

    Beschreibung: Coloured, dissolved organic matter (CDOM), which represents a fraction of dissolved organic carbon (DOC),contributes strongly to the absorption of blue light in Baltic waters. This makes the Baltic an idealtest site for deriving DOC concentrations from ocean colour imagery. Two hundred and five high resolution(1.3km) SeaWiFS images were processed using SeaDAS v.4.0 and combined into monthly composites of reflectance.A simple, in situ-generated reflectance ratio algorithm was used to derive CDOM absorption at 440nm (ag440),and an algorithm from the literature was applied to derive DOC concentrations, with a constant CDOM spectralslope coefficient of 0.019nm{^-1} to extrapolate to the required DOC-algorithm wavelength. Temporalresolution was restricted by cloud cover and by solar illumination conditions: only monthly composites fromMarch to October were practical. Surface DOC concentrations ranged between 4 and 5mgl^{-1}, with elevatedvalues in the cloudiest months (March and October). An increase in surface DOC lagged behind the annualcyanobacterial bloom, which peaked in July, by one month. Assuming a constant DOC profile, basin-integratedDOC estimates for the Baltic of 0.3{/pm}0.04Tg were obtained. The major contributions to error in thistechnique were evaluated.

    Beschreibung: Radiocarbon-dated pollen, rhizopod, chironomid and total organic carbon records from NikolayLake (73°20'N, 124°12'E), Arga Island, Russia reflect mid- to late Holocene vegetation andclimate changes in the Lena Delta area. Shrubby Alnus fruticosa and Betula nana tundra existedon Arga Island during 6000-4200 14C yr BP, and gradually disappeared after that time. Pollen-based climate reconstructions suggest that climate was relatively warm during 6000-5300 14C yrBP, and rather unstable between ca 5100-3500 14C yr BP. Both qualitative interpretation of pollendata and results of quantitative reconstruction imply that climate and vegetation became similarto modern-day conditions after ca 3400 14C yr BP.
