Krishnapriya Tamma

I am an ecologist, with an interest in tropical forest diversity, dynamics and biogeography. My PhD dissertation was on the biogeography and macroecology of small mammals in the Indian subcontinent (esp in the Himalayas). My postdoctoral work was on African tropical forest-savanna dynamics. As part of my long-term research, I am interested in understanding forest recovery in northeast India and how human activities influence recovery. I continue to be interested in the biogeography of birds, especially tropical frugivores.
