Multiple births in Homo sapiens - Disentangling stable and dynamic heterogeneity
Historical demographic data from Homo sapiens (across several European countries) are used to generate life-history simulations that enable the disentanglement of between- and within-individual variation in demographic life-history traits.
Gradual environmental change versus Single catastrophe-Identifying drivers of mammalian evolution
By combining climate reconstructions, molecular genetic data and species distribution data from the Late Pleistocene (126-13.7 thousand years ago) to the present we evaluate the impact of two key drivers shaping mammalian diversity in a Southeast Asian biodiversity hotspot, the Sunda Shelf.

Paternal epigenetic effects: Do fathers transmit their experiences to their sons?
Epigenetic changes function as flexible mechanisms to increase adaptability within a generation and transmit the environmental information to subsequent generations in vertebrates. In times of global warming and changing vegetation, we aimed to study the epigenetic response of a wild mammal species, the wild guinea pig, to an increase in temperature (of 10°C more than ambient) as well as to a diet alteration (of 40% less protein). We measured the direct epigenetic response in male wild guinea pigs and also studied whether, and if so to what degree that response was also transmitted to their sons. We detected transmission of epigenetic information from fathers to their sons.
