Ostracode Research Activities in

YUGOSLAVIA

Krstic, Nadezda. Nadezda’s main topic of research is the evolution of the lacustrine sedimentary cycles of the between Mediterranean and Paratethys. Lacustrine cycles differs from marine for "half a step (Krstic, 1999a). The position of the region on the transition from temperate to subtropical climatic belts produce fast alternation of the water chemistry in different lakes. By the means of ostracodes, as highly sensitive organisms, all the changes could be traced nearly to the heavy mineralised water, poisoned for any of organisms, when from solution the mineral ores precipitate. Saline is always the middle part of a sedimentary cycle. There is some abberations of salinity, like in the Upper Pliocene of Kosovo (Krstic,;1998a). Many curious ostracodes, mostly Candoninae, were dwellers of the more or less saline lakes the continuity of a long evolution of ostracodes lasting, at least for whole Tertiary. Scarcity of in continental areas and diversity of ostracode assemblages make difficult obtaining now a more clear picture. Some distant communities, for ex. Early Eocene of eastern China (Guan, 1997, in: Acta Micropal. Sin., 14/3) and the Pliocene of the Middle Danube (Pannonian) basin (Sokac, 1978, in: Paleont. Jug., 20) strucks by its simillarity.

Rundic, Ljupko. I am continuing my research on Miocene caspibrackish ostracodes of Yugoslavia, Bosnia and the other part of Paratethys. In relation with that, I attended on Paratethys Neogene Stratigraphy Workshop last July on Comenius University, Bratislava-Slovakia. There colleageous from Poland, Czeck, Slovakia, Hungary, Romania, Ukraina and Yugoslavia worked on three main topics: 1) to define the most problematic boundaries in Neogene of studied region; 2) to define the most used stratigraphic biozones and their correlation to mA ages; 3) to compare the observed reflection of the eustatic changes in studied area with global curve (Haque, 1987). As conclusions, I hope that we will prepare joint report for this year. 13th Yugoslav Geological Congress held in Herceg Novi, Monte Negro last October with about 300 articles (summary in English). I presented a paper (with S. Mitrovic) on modern terminology in stratigraphy and biostratigraphy. Dr Natalia Trofimovich from Lvov University, Ukraina (she works on forams) visited some Neogene localities of Serbia and Bosnia. She collected samples from marine Badenian sediments and we will prepare some common articles. Current research includes: 1) Neogene marine and caspibrackish ostracodes of Bosnia and Yugoslavia; 2) Biostratigraphy and paleoecology of freshwater ostracodes from some Miocene lakes of Serbia.

Zlatko, Jecmenica. Jecmenica, a former member of the Tuzla University (East Bosnia) staff, pushed by the war to Ugljevik coal mine, just started its research of the Lower Miocene lacustrine ostracodes, from NE Bosnia.
