Dr. Dirk Karger

Research Interest

I am a senior researcher at the interface of macroecology, biodiversity research, and climatology. My research focuses on how climate and biodiversity are linked in time and space. A focus of my recent work has been the development of algorithms to downscale climate data to the biologically relevant scales needed for ecological studies. I am currently studying how extreme weather and extreme events, such as megadroughts, affect vegetation and biodiversity. I have also done extensive work on the geography and biodiversity of cloud forest ecosystems in the tropics and the biogeography of tropical islands.
