Titleimage: Behavioural Ecology

In the Division of Behavioural Ecology, we study the evolutionary mechanisms that shape animal behaviour in an ecologically relevant context. Specific research topics include parental decision making, parental effects and the development of social behaviour, evolution of complex sociality and cooperation, communication networks, cognition, animal personality, and life history strategies. As model systems we currently use Neotropical poison frogs, Cichlid fishes of Lake Tanganyika, and Tokay geckos. We study these animals in the lab as well as in their natural habitat, by combining a diverse set of methodological approaches, including behavioural experiments, ecological manipulations, theoretical modelling, video monitoring, molecular parentage and kinship analyses, gene expression studies, endocrinological manipulations, GIS analyses, and automation of cognitive test designs.

New SNSF project

New research project on the reproductive ecology of glassfrogs was just funded by the SNSF! We will study three species of glassfrogs with different mating and parental care systems regarding their space use, communication strategies, and cognition.


New Head of Division

Eva Ringler takes over the Behavioural Ecology Division from Michael Taborsky. Thanks to the warm welcome of the entire Hasli team! Very looking forward to exciting times to come!
