Project overview

 

Due to their longevity and limited biotic exchange with adjacent ecosystems ancient lakes are stages for radiation in various organisms resulting in extraordinary diverse, largely endemic and highly morphologically plastic biota. Thus, ancient lakes are a perfect setting to study evolutionary processes. This has been clearly demonstrated in several Recent ancient lakes (e.g., Lake Tanganyika, Lake Baikal) what has enormously influenced basic concepts in evolutionary biology. Among many other biota, within ostracods amazing species flocks developed in such lakes. These minute aquatic crustaceans with bivalved low-Mg calcite shells have an excellent fossilisation potential and reach high abundances in lake sediments. This makes them also attractive for studies in "deep time", however, limited to their hard parts and therefore to their phenotypes. In the Miocene period the Palaeo-ancient lakes Lake Pannon (Central Europe) and Lake Pebas (Western Amazonia) were centres of ostracod diversification with hundreds of endemic species. Most of these taxa are mainly based on qualitative descriptors following a strict morphotype concept, paying little attention to morphological plasticity. As a result robust phylogenies, conclusive biostratigraphic zonal schemes and sound palaeo(bio)geographic considerations are still missing. To overcome these problems we will analyse the dynamics of ostracod assemblages with high-resolution samples down to 5 mm vertical sampling distance, representing time intervals of hundreds to tens of years. These results will be combined with multi-proxy palaeoenvironmental analyses based on, e.g., grain size distribution, carbonate, carbon, and sulphur contents, stable isotope ratios (oxygen, carbon) as well as magnetic susceptibility and gamma ray emission. Concerning ostracods we will focus on morphological traits of the cytherideid genus Cyprideis by using an extensive combination of traditional and geometric morphometrics, not neglecting qualitative characters at all and including investigations on juveniles to explore their developmental trajectories. Cyprideis is chosen because it is the best-studied Recent ostracod clade, dominating in aberrant environments and exhibiting a considerable amount of intraspecific variability. Both in Lake Pannon and Lake Pebas dozens of species were described and used for biostratigraphic dating and palaeo(bio)geographic reconstructions. We aim to evaluate (even subtle) changes in valve morphology on high-resolution key sections spanning in total several millions of years, try to explore possible extrinsic/intrinsic triggers and reconstruct evolutionary pathways. Extremely challenging and promising is the examination of the capacity of these phylogenetic lineages to respond to environmental changes. To test such interrelationships ideal candidates are Central Europe's Lake Pannon and western Amazonia's Lake Pebas, located in two completely different geographic areas reflecting also different histories but somewhat comparable palaeoenvironmental settings. Our investigations might result in an improvement of species delineation, a better understanding of speciation and a well-constraint reconstruction of their phylogeny. Of particular interest is the resolution of evolutionary patterns in terms of parallel and iterative evolution versus convergence. Thus, we aim to contribute desperately needed basic data to general questions of evolutionary processes.
