The Coume Ouarnède System, a Hotspot of Subterranean Biodiversity in Pyrenees (France)
diversity Article The Coume Ouarnède System, a Hotspot of Subterranean Biodiversity in Pyrenees (France) Arnaud Faille 1,* and Louis Deharveng 2 1 Department of Entomology, State Museum of Natural History, 70191 Stuttgart, Germany 2 Institut de Systématique, Évolution, Biodiversité (ISYEB), UMR7205, CNRS, Muséum National d’Histoire Naturelle, Sorbonne Université, EPHE, 75005 Paris, France; [email protected] * Correspondence: [email protected] Abstract: Located in Northern Pyrenees, in the Arbas massif, France, the system of the Coume Ouarnède, also known as Réseau Félix Trombe—Henne Morte, is the longest and the most complex cave system of France. The system, developed in massive Mesozoic limestone, has two distinct resur- gences. Despite relatively limited sampling, its subterranean fauna is rich, composed of a number of local endemics, terrestrial as well as aquatic, including two remarkable relictual species, Arbasus cae- cus (Simon, 1911) and Tritomurus falcifer Cassagnau, 1958. With 38 stygobiotic and troglobiotic species recorded so far, the Coume Ouarnède system is the second richest subterranean hotspot in France and the first one in Pyrenees. This species richness is, however, expected to increase because several taxonomic groups, like Ostracoda, as well as important subterranean habitats, like MSS (“Milieu Souterrain Superficiel”), have not been considered so far in inventories. Similar levels of subterranean biodiversity are expected to occur in less-sampled karsts of central and western Pyrenees.

Accepted 9 August 2000. Abstract South America is diverse in climatic and thus vegetational zonation, and even the uniformly looking tropical rain forests are a mosaic of different habitats depending on the soils, the regional climate and also the geological history. An important part of the nutrient webs of the rain forests is formed by the terrestrial Isopoda, or Oniscidea, the only truly terrestrial taxon within the Crustacea. They are important, because they participate in soil formation by breaking up leaf litter when foraging on the fungi and bacteria growing on them. After a century of research on this interesting taxon, a revision of the terrestrial isopod taxa from South America and some of the Antillean Islands, which are traditionally placed in the family Philosciidae, was performed in the last years to establish monophyletic genera. Within this study, the phylogenetic relationships of these genera are elucidated in the light of phylogenetic systematics. Several new taxa are recognized, which are partially neotropical, partially also found on other continents, particularly the old Gondwanian fragments. The monophyla are checked for their distributional patterns which are compared with those patterns from other taxa from South America and some correspondence was found. The distributional patterns are analysed with respect to the evolution of the Oniscidea and also with respect to the geological history of their habitats. -

A Survey of Gill and Digestive System Parasites of Brownbanded Bambooshark Chiloscyllium Punctatum from the Gulf of Thailand
A Survey of Gill and Digestive System Parasites of BrownBanded Bambooshark Chiloscyllium punctatum from the Gulf of Thailand Wiriya Chaiyaroj Faculty of Fisheries, Kasetsart University Abstract The species of benthic shark, BrownBanded Bambooshark (Chiloscyllium punctatum) were collected from Exclusive Economic Zone of the Gulf of Thailand. Fish samples were examined both of external and internal parasite. 15 samples of sharks found only 12 sharks that infected with parasites. Two family of endoparasites, family Onchobothrithriidae and family Phyllobothriidae of phylum platyhelminthes were found highest prevalence and mean intensity at gastrointestinal especially at the intestine that unidentified. Three genus of ectoparasites, Eudactylina Gnathia and Caligus were found at the gill area. They had prevalence and mean intensity follow by intestine and that also unidentified species. Introduction Brownbanded Bambooshark (Chiloscyllium punctatum) is the small benthic shark in family Hemiscyllidae and distributed mainly in Southeast Asian water. This species taken in inshore fisheries in Thailand and utilized for human food. Nowadays, their status recognized as “Near Threaten” (Tassapon et al., 2560) The Gulf of Thailand looks like a basin that is an area of sediment from several rivers makes seabed like mud and sand are spread everywhere. (Department of Marine and Coastal Resources, 2013) and benthic sharks are located in the sand or sand along the coast. (Tassapon et al., 2560). In the Gulf of Thailand, the genus of benthic sharks Chiloscyllium, there are 5 species. Chiloscyllium punctatum is the most abundant species in this genus and found in this cruise of M.V.SEAFDEC 2. (Tassanee et al., 2560) that caught by the trawl. -

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young. -
Host DNA Integrity Within Blood Meals of Hematophagous Larval Gnathiid Isopods (Crustacea, Isopoda, Gnathiidae) Gina C

Hendrick1,2, Maureen C. Dolan1,2, Tanja McKay1 and Paul C. Sikkel1* Abstract Background: Juvenile gnathiid isopods are common ectoparasites of marine fshes. Each of the three juvenile stages briefy attach to a host to obtain a blood meal but spend most of their time living in the substrate, thus making it difcult to determine patterns of host exploitation. Sequencing of host blood meals from wild-caught specimens is a promising tool to determine host identity. Although established protocols for this approach exist, certain challenges must be overcome when samples are subjected to typical feld conditions that may contribute to DNA degradation. The goal of this study was to address a key methodological issue associated with molecular-based host identifcation from free-living, blood-engorged gnathiid isopods—the degradation of host DNA within blood meals. Here we have assessed the length of time host DNA within gnathiid blood meals can remain viable for positive host identifcation. Methods: Juvenile gnathiids were allowed to feed on fsh of known species and subsets were preserved at 4-h intervals over 24 h and then every 24 h up to 5 days post-feeding. Host DNA extracted from gnathiid blood meals was sequenced to validate the integrity of host DNA at each time interval. DNA was also extracted from blood meals of wild-fed gnathiids for comparison. -

INTRODUCTION The Anthuridea have found increased interest during the last' few years and the number of known species is growing fast. These crustaceans are obviously present all over the world in the marine benthos and in some brackish and freshwater habitats. In the course of ex~editionsand benthic surveys of the last decades many new species were discovered, often with the help of diving techniques and by careful sorting of the samples. At present 57 genera and 321 species are known. In table 1, one can see how many spe- cies were described only in the past 10 years. For someone who is not constantly following the taxonomic publicat- ions it is difficult to find out which names are valid today, what synonyms exist, how many species are known and from which part of the world. The present paper will help those who are not familiar with this group of Isopoda to get the necessarv information. (7 It is not possible for us to revise those genera which are still in an unsatisfactorv condition. as the material for the necessarv redescri~tions , I was not available.
