Ostracode Research Activities inBELGIUM
Correspondent: Karel Wouters <kwouters@kbinirsnb.be>
Casier, Jean Georges. Jean is continuing research on Upper Paleozoic ostracodes from the world, particularly in relation with the Late Devonian mass extinction (Frasnian/Famennian boundary) and with the Hangenberg event (Devonian/Carboniferous boundary). He is currently working, in collaboration with Francis Lethiers (University Paris VI), on ostracodes from France, Germany, Poland, Nevada and New-York.
Coen, Michel. Michel continues working on Tournaisian ostracodes of Guangxi, southern China. Together with Peter Jones, he also became interested in paraparchitids and knoxiellids from the Devonian-Carboniferous transition beds in the Ardennes, the Russian platform and the Bonaparte basin of NW Australia. The revision of various taxa related to one or another of the preceeding topics further led him to go and examine the Grundel collection in Freiberg and the Kummerow collection in Berlin (Spandau).
Martens, Koen. Koen is continuing studies on taxonomy, morphology and ecology of non-marine ostracodes from Africa and the Levant. In addition he is working on the comparative and evolutionary ecology of zoobenthos in large and ancient lakes (Baikal, Tanganyika, Nyasa/Malawi and Titicaca), partim ostracods. Taxonomy of Tanganyikan Cytherideidae is conducted together with Karel Wouters, Tanganyikan Gomphocythere is studied with Lisa Park, Lake Baikal ostracodes are studied in collaboration with Galina Mazepova, those of Lake Titicaca together with Philippe Mourguiart. Koen is also working on comparisons between morphological and molecular evolution in the Cytherissa species flock in Lake Baikal and the Cyprideis species flock in Lake Tanganyika (with Isa Schön). He continues his interest in DNA-repair and general purpose genotype in darwinulid ostracodes (with Isa Schön, Roger Butlin and Karine Van Doninck). Koen is working on the revision of Darwinuloidea with G. Rossetti (Recent), Mesozoic (with Dave Horne) and Palaeozoic (with F. Lethiers). Another project is focused on the origin and evolution of non-marine Cyprididoidea (with Dave Horne). For the Treatise, he is working on post-Cretaceous non-marine Cypridacea, Limnocytheridae and Darwinulacea. Last year, he edited the book "Sex and Parthenogenesis, Evolutionary ecology of reproductive modes in non-marine ostracods" (Backhuys Publ., Leiden, 1998), the proceedings of the "Jan Stock Memorial Symposium" (with Dan L. Danielopol, special issue Crustaceana 1999) and the proceedings of the ISO 97 symposium (with Dave Horne, "Evolutionary biology and ecology of Ostracoda", special issue Hydrobiologia 1999).
Schön, Isa. Isa is working on comparisons between morphological and molecular evolution in the Cytherissa-flock from Lake Baikal and the Cyprideis-flock from Lake Tanganyika (with Koen Martens). In addition, research is focused on DNA repair and general purpose genotype in darwinulid ostracods (with Koen Martens, Roger Butlin and Karine van Doninck) and the molecular phylogeny of the Darwinulidae (with Koen Martens and Giampaolo Rossetti).
Wansard, Guy. Guy is working on the incorporation of trace-elements in lacustrine ostracode valves. He is preparing papers that discuss geochemical results obtained from laboratory cultures of Candona neglecta and Heterocypris salina, and from field collection of Herpetocypris intermedia (in collaboration with Dr J. R. Roca and F. Mezquita, Valencia University). He is also working on paleoclimate and paleoenvironmental reconstructions from Quaternary sequences, including lacustrine ostracode assemblages and valve geochemistry studies in Spain (in collaboration with the team of Prof. R. Julia, Barcelona), in Bolivia (in collaboration with Prof. Pirard, University of Liège, Belgium, and Prof. Pool, University of Oruro, Bolivia), and in Belgium (Holocene tufa sequences).
Wouters, Karel. Karel is continuing research on marine and brackish Cypridacea, mostly from the Indian and Pacific Oceans. This resulted in the description of a new genus. He is also reviewing the complex taxonomical imbroglio of the genera Phlyctenophora, Aglaiocypris, Aglaiella, Ghardaglaia and Gerdocypris. Further projects are: (1) description of new species of the Cyprideis species flock of Lake Tanganyika (in collaboration with K. Martens). (2) The temporal distribution of the genus Liasina, a low diversity lineage. (3) The taxonomic position and the (palaeo)-zoogeography of the family Saididae. He is supervising the Licentiate thesis of Ronald Gravendeel (University of Leuven) on Eocene (Lutetian) Ostracoda from Cassel (N. France).
