研究领域

My research interests are covering a broad range of animal ecology focussing on animal behaviour, behavioural ecology, population biology, evolutionary ecology and conservation. My main interest is in understanding individual differences in behaviour and ecology. In my current research on Columbian ground squirrels (Spermophilus columbianus) and Alpine ibex (Capra ibex) I study the evolution of different mating systems and mating tactics as well as life-history trade-offs leading to individually optimised reproductive success in both sexes. To do so I connect my behavioural ecology based research with other research fields such as genetics, parasitology and behavioural endochrinology. Some specific topics: animal personalities, mate choice, reproductive success, mating tactics, parasite – host interactions, hormones stress and reproduction, population dynamics and global warming
