    The urosome of the Pan- and Peracarida (2006)

    Description: We have examined the caudal regions of diverse peracarid and pancarid malacostracans using light and scanning electronic microscopy. The traditional view of malacostracan posterior anatomy is not sustainable, viz., that the free telson, when present, bears the anus near the base. The anus either can occupy a terminal, sub-terminal, or mid-ventral position on the telson; or can be located on the sixth pleomere – even when a free telson is present. Furthermore, there is information that might be interpreted to suggest that in some cases a telson can be absent. Embryologic data indicates that the condition of the body terminus in amphipods cannot be easily characterized, though there does appear to be at least a transient seventh segment that seems to fuse with the sixth segment. Our understanding of the genesis of the so-called telson of amphipods could be subject to alternative interpretations than those traditionally put forth.

    Sex ratio and sexual selection in wormshrimps (Crustacea, Amphipoda, Ingolfiellidea) (2006)

    Description: Small populations of several species of the groundwater dwelling amphipod genus Ingolfiella are found in caves, wells, seabottoms, beaches and riverbed interstitial habitats. To gain insight in the socio-ecology of these elusive species, we used data from collected specimens to explore the relationships between sexratios, display of secondary sexual characters and other morphological features, and habitat use. We extracted data on the sex ratios and the presence-absence of secondary sexual characters of 13 species from the literature and through examination of museum material. We found a clearly skewed sex ratio with a preponderance of females, both in the individual species as in the genus as a whole. However, sex ratio and the display of secondary sexual characters were not correlated, nor did these characters correlate with the amount of sexual dimorphism. It remains unknown why so many ingolfiellids have evolved these costly features.

    Cladistic analysis of the family Stenothoidae (Amphipoda, Crustacea) (2006)
    In:  Contributions to Zoology (13834517) vol.75, 3/4 (2006) p.169

    Description: The amphipod family Stenothoidae contains more than 200 species in about 40 genera; these genera are at present often defined not by the presence, but by the absence of synapomorphies, thus defining grades rather than clades. Our phylogenetic analyses yielded 4 groups of stenothoids: a basic proboloidid clade; an advanced and always clearly separated Austral-Antarctic thaumatelsonid clade, with a possibly related Arctic mesometopid clade; and finally a poorly resolved group, the stenothoids sensu stricto, including the large and probably polyphyletic genera Stenothoe and Metopa, each with more than 50 species. It is proposed to study and analyse these groups separately in future, based on better redescriptions of the individual species. Our analyses support the family status of the Thaumatelsonidae, erected as a family by Gurjanova in 1938, but reduced to subfamily rank by Barnard in 1972.

    Description: Two new brachyuran species are described for the Upper Cretaceous Mexcala Formation, Guerrero State, Mexico. Longusorbis quadratus new species (Coniacian, Temalac region) is the oldest and southernmost record for the genus. Xanthosia zoquiapensis new species (Campanian, Zoquiapa region) is the first record for the genus in Mexico. In addition, the age for Costacopluma bishopi Vega and Feldmann is discussed (Coniacian, Temalac region) and represents the oldest and southernmost record for Cretaceous representatives of this genus in North America. All specimens are considerably smaller compared to other species of the same genera and are interpreted as the first example of brachyuran dwarfism in the geological record. These species add new insight into possible migratory routes during the Late Cretaceous. Within Longusorbis, a northwestern migratory route is documented from the Coniacian in Mexico to the Campanian - Maastrichtian of the west coast of North America (Canada), whereas within the genus Xanthosia, a western migratory route from the Albian of Europe to the Campanian of Mexico is indicated. Costacopluma migrated east and north to the west coast of Africa, southeast North America and Greenland.

    Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia (2006)
    In:  Scripta Geologica (03757587) vol.133 (2006) p.19
    Details
    Publication Date: 2007-01-09
    Description: The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachyrotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two families, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be characterised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few species in the Pebas fauna include important ecological groups, such as indicators of marine influence (e.g., Nassariidae, one species), terrestrial settings (e.g., Acavidae, one species) and stagnant to marginally agitated freshwaters (e.g., Planorbidae, four species). Only seven species (4%) representing undisputedly elevated salinities were found, whereas 31 species (20%) are undisputed restricted to freshwater biotopes. Only three (2%) terrestrial gastropod species are known. The Pebas system experienced profuse radiations of molluscs that led to an overwhelmingly endemic fauna, typical of a long-lived lake environment. Several extant genera, which nowadays live outside Amazonia, may have originated within the Pebas system. The stratigraphic continuity of species and line ages, at least for the late Early-early Late Miocene interval (c. 18-9 Ma), indicates that lakes continuously occupied the system and never were entirely replaced by rivers or the sea. The rare occurrence of marine taxa indicates that the system was at sealevel and occasionally experienced marine incursions.

    Gulella johannae spec. nov. (Gastropoda, Pulmonata, Streptaxidae), a new land snail from the Drakensberg range in Limpopo Province, South Africa, with notes on G. johannesburgensis (M. & P.) (2006)

    Publication Date: 2010-12-12
    Description: Gulella (s.l.) johannae n. sp. is described from a few forest localities in the Tzaneen District, Limpopo Province, South Africa. It is characterized by a cylindrical, costulate shell with an almost entire peristome and a four-fold apertural dentition consisting of a prominent angular lamella (delimiting an only here discontinuous peristome), a mid-labral denticle, a left basal denticle, and a mid-columellar process. The shell is somewhat similar to that of G. johannesburgensis, but is consistently larger and more slender and has more whorls, while at the same time the apertural dentition is better developed; the almost uninterrupted peristome also appears to be a signifi cant character. This new taxon most likely is a restrictedrange endemic on the eastern flanks of the northern Drakensberg escarpment. Numerical data of a lot of material identified and mostly also published as G. johannesburgensis show that probably not all specimens belong to this taxon so that more than one species may be involved here.

    Publication Date: 2014-11-07
    Description: A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae sensu lato, Xanthoidea sensu lato, or Goneplacidae sensu lato were evaluated as to their family level placement and as a result, the family-level placement of many of these genera has been changed herein. Balcacarcinus new substitute name, is provided herein for Bittneria Schweitzer and Karasawa, 2004.

    Materials for a more stable subdivision of the genus Uca Leach (2006)
    In:  Zoologische Mededelingen (00240672) vol.80 (2006) nr.4 p.9
    Details
    Publication Date: 2010-12-12
    Description: The debate on a proper subdivision of the large genus Uca was initiated by the conflicting proposals of Bott (1973) and Crane (1975). In spite of recent computer-aided mending attempts, the overall situation (instability of Uca systematics and nomenclature) has not convincingly improved. Here we try to settle the debate by presenting a simple cladistic analysis sensu Hennig (1950) based on selected morphological characters supplemented by functional remarks and a few behavioural data resulting from fieldwork. All 94 species (except six) were examined, mostly by using the authors’ collection of Uca (partly in Marburg and partly deposited in the Leiden Museum) and all species (see list in chapter 5) are assigned to one of the eight subgenera recognized: Australuca, Cranuca subgen. nov., Gelasimus, Leptuca, Minuca, Paraleptuca, Tubuca, Uca s. str. Some emphasis is laid on a differentiation within the synapomorphies selected: five “major unique inventions” (table 1) are delimited from normal apomorphic character states. The discussion is confined to zoogeographical conclusions, which refer to an early dispersal within “Wegener’s Indo-Atlantic Ocean” and which favour Australia as the centre of origin of the genus Uca.

    Miocene freshwater Mollusca from western Brazilian Amazonia (2006)
    In:  Scripta Geologica (03757587) vol.133 (2006) p.419
    Details
    Publication Date: 2007-01-09
    Description: Thirteen species of fossil molluscs are reported from the Solimões Formation of western Brazilian Amazonia. Based on mammalian chronology of the Solimões Formation and radiometric ages reported from coeval deposits in adjacent Peru, the age of the fauna is established as Late Miocene. The fauna includes five prosobranch gastropod species, seven pearly freshwater mussel species and one sphaeriid bivalve species. The supposed presence of Pachydon (Corbulidae: Bivalvia) in these deposits is rejected; Pachydon acreanum, whose status has long been uncertain, is transferred to the unionoid genus Callonaia. The Solimões mollusc fauna is entirely composed of obligate freshwater taxa, resembling species-poor modern Amazonian fluvial faunas. The presence of the fauna in outcrops covering large parts of western Amazonia indicates that by that time the preceding Pebas fauna (dominated by corbulid bivalves and cochliopid snails) must have been extinguished.

    Evolutionary ecology of the Pachydontinae (Bivalvia, Corbulidae) in the Pebas lake/wetland system (Miocene, western Amazonia) (2006)

    Details
    Publication Date: 2007-01-09
    Description: Miocene deposits in western Amazonia and adjacent areas of South America harbour a diverse suite of endemic corbulid bivalves, commonly referred to as Pachydontinae, that show a wide variety of morphologies. Especially in the Miocene Pebas Formation (Peru, Colombia and Brazil), this group diversified spectacularly. Since these corbulids (a cosmopolitan marine and perimarine bivalve family) occur with freshwater taxa and yield isotope signals strongly indicative of freshwater settings, the success of this group in inland basins of Miocene northwestern South America is surprising. In this paper it is argued that a combination of adaptations to fluid bottom substrates, common dysoxia and high predation intensities explains their abundance, their morphological diversity and the paucity of freshwater bivalve groups, such as Sphaeriidae, Corbiculidae and Unionoidea.

    Details
    Publication Date: 2007-01-15
    Description: Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region.

    The nature of aquatic landscapes in the Miocene of western Amazonia: an integrated palaeontological and geochemical approach (2006)
    In:  Scripta Geologica (03757587) vol.133 (2006) p.363
    Details
    Publication Date: 2007-01-09
    Description: The Miocene Pebas Formation from the section Santa Rosa de Pichana (Loreto, Peru) was investigated using a combination of analyses of sedimentary facies, molluscan communities and taphonomy, and stable isotopes of both entire shells and growth bands in bivalves. Three sequences, comprising a succession of transgressive, maximum flooding and regressive/prograding intervals, are documented. Molluscs are most common in the transgressive/highstand intervals and are almost absent in regressive/prograding intervals. The fauna is dominated by endemic Pebasian species, such as Pachydon and Dyris spp. The nature of the deposits as well as the availability of oxygen varied in a predictable way within each of the sequences and determined the nature of the assemblages. Highest diversity was reached in the late transgressive phase before the development of dysoxia that was widespread during the late highstand and early regressive/prograding phase. The mollusc and isotope data show no indications of elevated salinities, in contrast to ichnofossils found in the section. This discrepancy is interpreted to result either from temporal separation of the ichnofossils and the mollusc fossils or from evolution beyond usual ecological tolerances of taxa that produced these ichnofossils into freshwater settings.

    The stratigraphy and regional structure of Miocene deposits in western Amazonia (Peru, Colombia and Brazil), with implications for late Neogene landscape evolution (2006)

    Publication Date: 2007-01-15
    Description: A biozonation based on molluscs is proposed for Miocene deposits of western Amazonia (Peru, Colombia and Brazil), commonly referred to as the Pebas Formation. The new zonation refines existing pollen zonations and provides a key for the quick assessment of the stratigraphic position of Neogene deposits in the field. The regional distribution of twelve mollusc zones reveals a structuring of geological units around the broad Iquitos-Araracuara anteclise. The structure of the subsurface appears to have been a major factor in the determination of present-day second and lower order river courses in the study area. Based on this work a biostratigraphic framework for Miocene deposits of western Amazonia, including fossiliferous deposits from adjacent basins (Putumayo, Llanos and Magdalena basins in Colombia), is proposed.

    Description: Doto uva Marcus, 1955 is a nudibranch species recorded from the Brazilian and Chilean coast. In spite of its wide distribution, D. uva has been described only superficially, mainly as to the pattern of its coloration, external morphology, radular teeth and reproductive system. Here we substantially extend this description, paying special attention to the morphology, anatomy and histology of the digestive and reproductive system. Furthermore, new data on the morphology of the central nervous system and its cell types are given, and finally, the egg mass is described. On the basis of these data, we consider the Doto specimens described from Chile conspecific with those from Brazil.

    Miocene long-lived lake Pebas as a stage of mollusc radiations, with implications for landscape evolution in western Amazonia (2006)
    In:  Scripta Geologica (03757587) vol.133 (2006) p.1
    Details
    Publication Date: 2007-01-09
    Description: The Miocene Pebas system was a huge (〉 1 million km2) system of long-lived lakes and wetlands that occupied most of western Amazonia between c. 23 and 8 Ma. Remarkable endemic radiations of molluscs and ostracods occurred in the Pebas system. The continuity of many of the endemic lineages between c. 17 and 9 Ma shows that the system was never fully replaced by fluvial or marine settings. Many of the endemic invertebrate groups developed an unusual range of morphologies that reflect adaptation to specific ecological stresses provided by the Pebas system, such as chemical stress, common dysoxia and high predation pressure. Mollusc diversity increased especially during the Middle Miocene. The Pebas system provided pathways for mobile marine organisms to transfer into freshwater biotopes, and at the same time obstructed exchange of terrestrial biota between the tropical Andes and the Guyana region. Short-lived, lowland aquatic corridors over northern shield regions and through the Ecuadorian Andean region almost certainly existed. The Pebas system was terminated just before the establishment of the modern Amazon system (slightly before 8 Ma), possibly coinciding with a single, wide ranging marine incursion into lowland Amazonia. With the termination of the Pebas system, the endemic mollusc fauna became largely extinct. The termination of the Pebas system provided large tracts of land for the establishment and development of terrestrial biota in western Amazonia. Subsequent diversification in lowland Amazonia has been enhanced by the edaphic heterogeneity of the Pebas Formation deposits.

    Description: During the DIVA-2 cruise (May 31 - July 4, 1994, see Desbruyères et al., 1994) and the PICO cruise (June 25 – July 11, 1998, N/O Nadir, PI: D. Desbruyères) to the Azores Triple Junction Area, two rare species of caridean shrimp were collected. Seven specimens of the pandalid Plesionika alexandri (A. Milne Edwards, 1883) were collected at the Lucky Strike hydrothermal vent field (37°20’N), and one specimen of the pontoniine Periclimenes kornii (Lo Bianco, 1903), at the Menez Gwen hydrothermal vent field (37°50’N). These hydrothermal vent fields are located on the Mid-Atlantic Ridge SW of the Azores. Both species of shrimp are only known from a few specimens. The original description of Plesionika alexandri was based on an incomplete specimen. It is now re-described on the bases of the present material

    Description: Two new species of sesarmid crabs are described from the mangroves of Timika in Papua (= Irian Jaya), Indonesia. Haberma kamora spec. nov. is the second species in the genus described from Singapore, differing from the type species in the form of its male first pleopods and possessing relatively more slender ambulatory legs. Parasesarma charis spec. nov. resembles P. erythrodactyla, P. tripectinis and to some extent, P. lepidum, but has different ambulatory leg proportions and a distinctive male first pleopod structure. Parasesarma acis Davie, 1993, is regarded as a junior synonym of P. tripectinis Shen, 1940.

    Neogene fossil tonnoidean gastropods of Indonesia (2005)

    Details
    Publication Date: 2007-01-12
    Description: Tonnoidean gastropods in K. Martin’s and other collections in the Nationaal Natuurhistorisch Museum, Leiden (and a few other minor collections) are reidentified and classified. The resulting fauna of 99 species is very similar to that of the Indo-West Pacific today, 70% of species still inhabiting the Indonesian region. Species endemic to the Miocene and Pliocene rocks of Indonesia are Bursa sangirana sp. nov., and two new (unnamed) species similar to Bursina ignobilis (Beu); Cassis depressior Martin and C. preangerensis Martin; Cypraecassis denseplicata (Martin) and an unnamed species of Cypraecassis; Sconsia martini van Regteren Altena and S. pulchra Pannekoek; Echinophoria vandervlerki Martin (possibly a synonym of E. wyvillei (Watson)); Phalium menkrawitense Beets and P. rembangense (Martin); Distorsio denseplicata van Regteren Altena and D. djunggranganensis (Martin); Biplex magnifica (Martin), B. pamotanensis (Martin) and B. perliberalis (Beets); Cymatium (Monoplex) gembacanum (Martin) (?=C. exaratum (Reeve)), C. rembangense (Wanner & Hahn), and C. tjaringinense (Martin); Cymatium (Ranularia) pseudopyrum (Martin) and an unnamed species of C. (Ranularia); Cymatium (Septa) dharmai sp. nov.; Sassia (Cymatiella) fennemai (Martin), S. (C.) menkrawitensis (Beets) and an unnamed species of S. (Cymatiella); Eudolium erbi (Haanstra & Spiker), E. errabundum (Beets) and E. pamotanense (Martin); Malea(?) papuana (Beets); and Sconsodolium (gen. nov.) rembangense (Pannekoek). These 30 species (30% of the recorded fauna), and the generic groups Sconsia, Sconsodolium and Sassia (Cymatiella), are all “additional” tropical western Pacific taxa that became extinct before the present day (Sconsia and Sassia (Cymatiella) only locally), as a result of Pleistocene climate change. Species previously included in Bufonaria Schumacher prove to belong in two distinct genera; species closely related to “Bursa” nobilis have a subcentral (rather than mid-left edge) opercular nucleus and are reclassified in Bursina Oyama. “Sconsia” rembangensis Pannekoek is an elongate, axially ridged cassid with a coarsely plicate inner lip; the new genus Sconsodolium is proposed for it. Galeodea bituminata (Martin) and G. carolimartini Beets are both earlier names for the western Pacific species (originally described in the Recent fauna) previously known as G. echinophorella Habe. Eudolium javanum (Martin) is an earlier name for the Indo-West Pacific species (originally described in the Recent fauna) previously known as E. pyriforme (G.B. Sowerby 3rd), whereas E. bituminata Martin is a synonym of the near-cosmopolitan species E. bairdii (Verrill & Smith). Ranella spinosa var. granosa Martin is either an earlier name for the western Pacific species (originally described in the Recent fauna) previously known as Bufonaria perelegans Beu, or a closely similar, but distinct, species. Purpura bantamensis Martin, Cassis tegalensis Martin, Dolium losariense Martin, and Tritonium verbeeki Boettger are all synonyms of Cymatium (Linatella) cingulatum (Lamarck).

    Two new genera and three new species of subterranean cyclopoids (Crustacea, Copepoda) from New Zealand, with redescription of Goniocyclops silvestris Harding, 1958 (2005)

    Description: A small collection of copepod samples from several wells in the Canterbury region, South Island, was examined. It contained a few cosmopolitan cyclopoid species, three interesting harpacticoids, as well as two new cyclopoid genera. The latter are presented in this paper, together with a redescription and first description of the male of Goniocyclops silvestris Harding, 1958, a cyclopoid species previously known only from North Island. Both new genera are from the Diacyclops-Acanthocyclops complex. Abdiacyclops gen. nov. is easily distinguishable from the complex by its unique swimming legs segmentation formula (2/2, 3/3, 3/3, 3/3), and is so far monospecific and known only after females. The most important characters of the second new genus, Zealandcyclops gen. nov. are: the swimming legs segmentation formula of 2/2, 3/2, 3/2, 3/2; a very small and two-segmented fifth leg; 11-segmented antennula; and sexual dimorphism in the swimming legs, with a transformed apical spine on the third leg endopod in the male. Four species were included in this genus: Zealandcyclops fenwicki sp. nov., from a well in the South Canterbury region; Z. haywardi sp. nov., from a well in the North Canterbury region; Z. eulitoralis (Alekseev and Arov, 1986) comb. nov., from the interstitial of several beaches on the southern shore of Lake Baikal; and Z. biceri (Boxshall et al., 1993) comb. nov., from a sandy beach on the western shore of Lake Baikal. Zealandcyclops gen. nov. seems to be an archaic cyclopoid genus, having survived only in New Zealand and in the ancient Lake Baikal. With the present report, the New Zealand cyclopoid fauna numbers 16 species, a systematic list of which is presented in this paper. The majority of them are cosmopolitan elements, probably introduced here by early European settlers. Only one genus (8%) and six species (38%) are endemic, which is probably a reflection of the absence of any comprehensive research on the New Zealand cyclopoids.

    Description: Strandesia kimberleyi n. sp. is described from subterranean waters of the Kimberley Region (Western Australia). It belongs to the group of relatively elongated Strandesia Stuhlmann, 1888 species, with no projection on the carapace and with a finely serrated posterior margin of the CR and its claws. The new species is characterized by the asymmetrical valves, elongated terminal segment of the maxillular palp, and the presence of a sensory organ antero-proximally on the first segment of the antennula. This is the first time that this organ is reported in the genus Strandesia. Strandesia purpurascens (Brady, 1886) is redescribed, while for S. variegata (Sars, 1901) and S. obliqua (Brady, 1868) some additional notes on the morphology are provided. A key to identification of 67 species of Strandesia is here given. This number includes a new species and two new combinations (S. iheringi (Sars, 1901) comb. nov., and S. mollis (Furtos, 1936) comb. nov.). Strandesia ewaldi is proposed as a nomen novum for S. labiata Roessler, 1990, while 31 species are proposed to be synonyms.

    Changes in the intertidal community structure after a mass mortality event in sandy beaches of Argentina (2005)

    Publication Date: 2014-11-07
    Description: After a massive mortality of the dominant species (the clam Mesodesma mactroides) occurred in 1995, changes in the intertidal community in sandy beaches of Argentina were monitored. Eight sampling stations were established in a 40 km open stretch and samples were taken every October each year up to 2001. Biomass, density, size frequency distribution and mean growth rates for the most abundant species were analyzed. During the mortality event, only the benthic stages of M. mactroides were affected, their total mean biomass diminishing from 1,399 g to 2 g per running meter beach. Post-mortality recruitment was normal and the growth rates for the youngest cohorts were similar to those previously reported. After a two years’ lag, the wedge clam Donax hanleyanus replaced M. mactroides as the dominant species, increasing from 6.0 g/m up to 24.3 g/m. However, dominance replacement did not restore the productivity of the intertidal macrobenthic assemblage and, despite the increment of D. hanleyanus stocks, the community total biomass remained 〈 1% of the pre-mortality levels. Since 1998 on, M. mactroides and D. hanleyanus showed several peaks in abundance. Disturbance, mainly due to non-regulated fisheries, has been delaying the community recovery. Taking into account the interactions among species and human activities, the present individual resourcebased management should be replaced by an integrated systembased management program including both conservation and tourism requirements.

    Publication Date: 2007-01-15
    Description: For fossil verrucid barnacles, the name Verruca withersi appears to have been used twice; Schram & Newman described material from the Albian-Cenomanian (Cretaceous) of Colombia, while Kruizinga had previously recorded a new species from the Pleistocene(?) or perhaps younger strata of Sumba (Indonesia). We do not consider V. withersi Schram & Newman to be a cirripede, therefore no replacement name is needed for this junior synonym. Verruca withersi Kruizinga is a valid species related to the extant V. cookei.

    Revision of the genus Spermophora Hentz in Southeast Asia and on the Pacific Islands, with descriptions of three new genera (Araneae: Pholcidae) (2005)
    In:  Zoologische Mededelingen (00240672) vol.79-2 (2005) p.61
    Details
    Publication Date: 2007-01-16
    Description: The main aim of the present paper is to delimit ‘true’ Spermophora, i.e. the group of species most closely related to the type species S. senoculata (Dugès). Apart from the type species, only three previously described species are included in this core group (S. estebani Simon, S. paluma Huber, S. yao Huber), together with nine newly described species: S. kerinci, S. tumbang, S. dumoga, S. maros, S. deelemanae, S. palau, S. kaindi, S. luzonica, and S. sumbawa. Except for the Holarctic and anthropophilic type species, all species have limited distributions in Southeast Asia, northeastern Australia, and the Pacific Islands, where they inhabit the leaf litter layer of tropical forests as well as caves. A tight correlation is documented in Spermophora between the male cheliceral apophyses (distance between the tips) and the pockets on the female external genitalia. In addition, three new Southeast Asian genera are described that appear similar to Spermophora but do not share the synapomorphies of the genus: Aetana n. gen. with three new species from the Philippines (A. omayan), Borneo (A. kinabalu), and Fiji (A. fiji); Savarna n. gen., with one new species from southern Thailand (S. thaleban) and two species from Sumatra and Malaysia transferred from Spermophora [Savarna tessellata (Simon) n. comb., and S. baso (Roewer) n. comb.]; and Khorata n. gen., with four new species from Thailand (K. bangkok, K. schwendingeri) and Laos (K. khammouan, K. jaegeri).

    A hitherto unnoticed adaptive radiation: epitoniid species (Gastropoda: Epitoniidae) associated with corals (Scleractinia) (2005)

    Description: Twenty-two epitoniid species that live associated with various hard coral species are described. Three genera, viz. Epidendrium gen. nov., Epifungium gen. nov., and Surrepifungium gen. nov., and ten species are introduced as new to science, viz. Epidendrium aureum spec. nov., E. sordidum spec. nov., Epifungium adgranulosa spec. nov., E. adgravis spec. nov., E. adscabra spec. nov., E. marki spec. nov., E. nielsi spec. nov., E. pseudolochi spec. nov., E. pseudotwilae spec. nov., Surrepifungium patamakanthini spec. nov., and ‘Epitonium’ crassicostatum spec. nov. and ‘E.’ graviarmatum spec. nov. Although their identities as separate gene pools are convincingly demonstrated by molecular data, some of these species cannot be identified unequivocally on the basis of conchological characters alone. The shell shape and sculpture are only partially diagnostic because of interspecifically overlapping character states. In most of these cases, the operculum, jaw structure, radula, spawn and/or the habitat do reveal the identity. Most of these species are associated with only one or a restricted number of coral host species and have large ranges, similar to those of their hosts.

    Increased genetic diversity in Greek populations of the genus Ligidium (Crustacea: Isopoda: Oniscidea) revealed by RFLP analysis of mtDNA segments (2005)

    Description: We investigated mtDNA genetic differentiation and the phylogenetic relationships of 11 populations of the oniscidean genus Ligidium. We studied nine populations from Greece, assigned to three nominal species (L. euboicum, L. germanicum and L. beieri), and two from central Europe (L. germanicum and L. hypnorum), applying RFLP analysis of two mtDNA segments (12S rDNA and 16S rDNA) amplified by PCR. The analysis revealed seven monomorphic and four polymorphic populations, and 17 different haplotypes, each one present in one population only. Several restriction enzymes produced population specific patterns, enabling discrimination among the different populations. The estimated net nucleotide divergence between populations ranges from 1.06 to 16.52%, while the high NST value (0.96) indicates the existence of increased interpopulation genetic differentiation that can be attributed to the extreme isolation among Ligidium populations. The relationships between haplotypes and populations are not congruent with their geographical distribution and the established taxonomy within the genus.

    Notes: Von der Vorstellung ausgehend, daß das Wasser der hauptsächlichste Mineralisator bei Eruptivgesteinsbildungen sei und das Magma eine wenn auch stark konzentrierte wässerige Lösung, wurden die für die gewöhnlichen wässerigen Lösungen geltenden Prinzipien auf die magmatische Lösung übertragen. Da wir in einer Lösung jeden beliebigen Lösungsgenossen als Lösungsmittel auffassen können, wurden die Mineralisatoren derart betrachtet, daß wir jeden derselben der Reihe nach als Lösungsmittel aufzufassen suchten.

    Notes: Die Versuche über den Basenaustausch im Permitit wurden fortgesetzt; beim Austausch des Kupfers gegen die Erdalkalien wurde die Unabhängigkeit von der Verdünnung für gleichwertige Ionen neuerdings bestätigt gefunden und gleichzeitig eine analoge Gesetzmäßigkeit im Verhalten der Homologen beim Austausch wie bei den Alkalien festgestellt. An der Reihe Silber-Barium wurde eine Formel für den Austausch zwischen ein- und zweiwertigen ionen erprobt und auch für die Reihe Natrium-Calcium gültig befunden; in dieser Reihe wurde außerdem eine Mischungslücke konstatiert und gezeigt, daß die Umwandlung der beiden festen Phasen  -  mindestens von einer Seite  -  beträchtliche Zeit braucht. Schließlich wurde noch am Austausch Silber-Lanthan gezeigt, daß auch dreiwertige Ionen zum Austausch befähigt sind und daß der Einfluß der Verdünnung hier besonders grß ist.

Dieselben wurden bisher aus den bei verschiedenen Verdünnungen (32, 64, 128, 256, 512, 1024) gemessenen Werten des molaren Leitvermögens μ nach der sogen. OSTWALD-BREDIGschen Regel dadurch extrapoliert, daß man nach einer von diesen Forschern gegebenen, auf empirischem Wege gefundenen Tabelle zu jedem Werte von μ ein Zahl addiert and nach der Gleichung \documentclass{article}\pagestyle{empty}\begin{document}$$ \mu _\infty ^ - = \mu + \Delta $$\end{document} den Wert von μ∞ findet.

    Notes: A. Es wurden folgende Methoden zur Darstellung des Gadoliniums geprüft: 1Die Alkalidoppelsulfatmethode.Die Methode erweist sich zur Darstellung des Gadoliniums nur bedingt als brauchbar. Ihre unbequeme Handhabung verbietet eine erschöpfende Anwendung zur Darstellung einer Einzelerde. Dagegen vermag sie gut Dienste zu leisten, wenn es sich darum handelt, ein umfangreiches schwachgadoliniumhaltiges Material in zwei Teile zu teilen, in deren einem man das Gadolinium konzentrieren kann.2Die Hydrazindoppelsulfatmethode.Diese Methode wurde neu ausgearbeitet; sie wirkt der Alkalidoppelsulfatemethode analog und in dem gleichen Sinne. Sie hat gegenüber jener den Vorzug, daß man die Menge der abzuscheidenden Erden in der Hand hat.Es werden die Hydrazindoppelsulfate einiger typischer Erden dargestellt und ihre Zusammensetzung durch Analyse ermittelt.3Die fraktionierte Kristallisation der Bromate.Diese von C. James zuerst angegebene Methode eignet sich in hervorragender Weise zur Trennung der Terbinerden von den Yttererden. Die Scheidung verläuft schnell und gestattet das Arbeiten in größtem Maßstabe, infolge der großen Löslichkeit und guten Kristallisationsfähigkeit der Bromate. Man kann jedoch mit ihr keine Trennung der Ceriterden von den Terbinerden erzielen, da die Löslichkeit des Gadoliniumbromats zwischen den Löslichkeiten von Samarium und Neodymbromat liegt. Die Methode muß also mit einer anderen, zur Abscheidung der Ceriterden dienenden verbunden werden.

    Notes: 1. Die Messungen der Reaktionstensionen, welche bei der Umsetzung von Schwefelblei mit seinen Oxydationsprodukten auftreten, wurden mit Erhitzungsröhrchen aus Calciumphosphat wiederholt. Dadurch werden die Fehler, welche bei der Verwendung von Silikatgefäßen auftreten, vermieden.

    Das Vorkommen des Polyhalits im älteren Zechsteinkalisalzlager, im Zusammenhange mit den Angaben van't Hoffs (1919)

    Notes: Die über das Vorkommen des primären und sekundären Polyhalits ausgeführten Untersuchungen stimmen mit den Angaben VAN'T HOFFS in vielem überein. Mit Ausnahme der carnallithaltigen Lagerteile kann der Polyhalit, in größeren oder geringeren Mengen, fast in allen kalihaltigen Teilen des älteren Zechsteinsalzlagers angetroffen werden. Als primär abgelagertes Salz tritt er hauptsächlich im stellenweise entwickelten polyhalitischen Steinsalz (Polyhalit-Halit) auf. In der kieseritischen Übergangszone (Hangend-Polyhalit) des Staßfurter Carnallitlagers treffen wir in der Gestalt des Anhydrits, Kieserits, Sylvins und Carnallits bereits nur sekundäre Umwandlungsprodukte dieses primären Polyhalits vor. Es haben eingesickerte Laugen des fortschreitenden Eintrocknungsvorganges, als auch die in der Tiefe erfolgte Einwirkung chlormagnesiagesättigter Laugen des Carnallitgebietes zu diesen Umwandlungsvorgängen beigetragen.
