Project B2

Project B2 – Palaeoenvironmental drivers of ostracod biodiversity change in Pontocaspian Basins - >University of Bucharest – ESR >Lea Rausch – Supervisor >Prof. Marius Stoica:

Ostracods are very sensitive to environmental (e.g. salinity) change. Major salinity changes occurred in successive lake phases during the Quaternary and faunal exchange occurred in episodic connections between basins. This project will focus on environmental drivers of ostracod turnover at the onset of the modern Pontocaspian system, the last glacial cycle and the Holocene (project C4) of the Caspian‐Black Sea basins. For each period the composition and diversity of faunas will be assessed from a number of sections and boreholes and compared to the sedimentary record and to mollusk fauna changes in the same sections in order to identify drivers of turnover, including anthropogenic (with project C4). Also, ostracod successions in satellite basins in Anatolia and the Balkans (project B3) will be studied to elucidate the role of these regions as source/sinks of Pontocaspian biota.
