Paolo Biella

Research Interests

Plant pollinator interactions and pollination ecology; network analysis; taxonomy of Hymenoptera (Apoidea) and Diptera (Anthomyiidae). I’m studying the structure of plant-pollinator networks in grassland with a focus on better understanding of mechanisms structuring the networks. I’m also working on habitat requirements and biogegraphy of bumblebees.
