Convergent and Adaptive Processes during Ecotype Formation

Collaborative project with Božo Frajman, Peter Schönswetter, Gilbert Neuner, Brigitta Erschbamer (University of Innsbruck, Austria), Christina Richards (University of South Florida, US) and Alex Widmer (ETH Zürich, Switzerland).

Project members from the University of Vienna: Ovidiu Paun, Aglaia Szukala, Emiliano Trucchi and Ruth Flatscher.

The project is part of the Vienna Graduate School of Population Genetics, funded thorugh the Doctoral Programs at Centers of Excellence (Doktoratskollegs - DK) of the Austrian Science Fund (FWF). In the past our research was funded by the Austrian Climate Research Programme (ACRP).

Heliosperma pusillum has developed in Southeast Alps two distinct ecotypes. The mountain ecotype (left down) differs morphologically with its dense indumentum from the glabrous, alpine ecotype (right down). Photos © Ovidiu Paun
