Rasmus Østergaard Pedersen

During his studies, MSc Rasmus Ø. Pedersen researched the ecology of mammals on global scale. This is a broad study in so-called macroecology, which is investigating the general trends in the impact of land-living mammals in nature during the last approx. 130 thousand years. Rasmus has worked with the ecological traits – as for example population density and diet – and has described some the changes that has happened after the extinction of several of the especially large mammals during the human global colonization.

The new research findings contribute to the understanding of the role of mammals currently compared to the past and increase our general knowledge of nature on a global scale. Furthermore the study brings basic knowledge, which can be used in nature restoration projects with a focus on restoration though natural dynamics of mammal species.
