A1.16 | AQUATIC EVOLUTIONARY ECOLOGY UNDER CLIMATE CHANGE CONDITIONS
Pliocene, Pleistocene and Holocene climate cooling and warming caused major range shifts and greatly affected the diversification of organisms. From the knowledge of how the evolutionary trajectories of lineages and species were affected by historic climate change, we can gain insight into how future changes may influence these species. One major question that we are addressing in several groups of aquatic insects is: How did past climate change effect diversification patterns in aquatic insects? To address this question my collaborators and I are examining the comparative phylogeography of aquatic highland insects in Europe, North America and South America (mayflies, stoneflies and caddisflies). Additionally we are examining the relationship between molecular and morphological diversification, trait evolution and niche evolution of several highly diversified groups of caddisflies. For example we are studying the effects of mountain uplift on speciation and trait evolution in the genus Smicridea in the Andes and selected clades of Rhyacophilidae in the Himalaya. Furthermore we are elucidating the role of palaeoclimatic and geological processes in the diversification of the micro-endemic rich Drusinae.
