Autecology

As a part of complementary studies in autecology, we study historical adaptation in terms of structure and lifestyle, the patterns and causes of species' distributions, and the influence of biotic and abiotic factors – especially in the context of seasonality – on the survival of individuals.
Phylogenetically controlled analyses and reconstructions reveal the evolutionary factors that have influenced interspecific variability in various morphological and behavioral traits. Satellite-aided analysis of vegetation allows us to study the distribution of different primate species from the local to the global scale.
Long-term climatic data, collected continuously, as well as data on the availability of plant-based foods and their ingredients, allow us to study the adaptation of primates with regard to their variability within a single year, and across years and decades.
