What do lake organisms reveal about climate change during greenhouse and icehouse world scenarios? – This fundamental question represents the key aspect of my general research interest that addresses the effect of climate change on lacustrine communities during the past 165 million years. Lakes and wetlands are biodiversity hotspots that are severely affected by modern global warming and associated shifts in lake surface temperatures. The limited ability of lake communities to respond to climate change by migrating along the water column1 renders lacustrine species especially sensitive to extinction. Consequently, “freshwater species are going extinct more rapidly than terrestrial or marine species”2. Palaeolake environments witnessed major re-organizations during the past 165 million years, including the mid-Cretaceous Hothouse, the Oligocene early Icehouse world, and the Pliocene–Pleistocene climate cooling leading to arctic glaciation. I study these crucial phases in Earth’s history as (reverse) analogues of possible future global change. I believe that a thorough understanding of animal growth strategies, biomineralization and habitat requirements is vital for the palaeoclimate interpretation of fossil data. Thus, my research follows a multidisciplinary approach that will, over the coming years, explore innovative ways to achieve the required precision for sub-seasonal climate reconstructions and to provide insights that have the potential to unravel the evolutionary history of lake ecosystems.
