046 Recent ecological change in ancient lakes

Across all continents of the world ancient lakes are widely recognized as not only hotspots of biodiversity, exhibiting spectacular species radiations which have contributed to high rates of endemism, but also exceptional record keepers, providing unusually long-term perspective on ecosystem relationships with climate and human activities. The latest report of the Intergovernmental Panel on Climate Change, together with other indices of land-use and pollution, show unequivocal evidence for environmental change at rates that have accelerated over the past century. Although ancient lakes (containing water since at least the last interglacial period) are unusual in many ways, they share common risks of human impacts experienced by lakes worldwide. In this session we seek to compare and contrast the dynamics observed in ancient lakes, from North to South across regions of widely varying geological and socioeconomic contexts, in order to understand the complex and often non- linear responses of aquatic ecosystems to anthropogenic perturbations. A broader examination of the spatial, temporal, biotic and abiotic factors underpinning ecosystem functioning is needed in order to assess the vulnerability and sustainability of these globally important ecosystems to current and future threshold changes.
