Collaboration with Oregon State University (Matthew Betts, Adam S. Hadley)
PhD student: Urs Kormann
Within the framework of the DFG research training group "Scaling Problems in Statistics" we are studying hummingbird pollination in tropical forests in Costa Rica (Las Cruces station). Using artificial feeders positioned along fencerows, we study connectivity and pollinator movement among rainforest fragments.
I have been involved in a DFG-funded project on tank bromeliads in the Neotropics:

Gallery forest and Inselbergs in the Ivory Coast (West Africa)
(with S. Porembski, N. Biedinger and others, University of Rostock; Image credits: S.Porembski)
This was a short-term research stay in 2000, where we collected plant material and did vegetation relevés on inselbergs in the Ivory Coast. Among other plant species, we found the carnivorous plant species Genlisea stapfii, Utricularia subulata, Utricularia juncea and Utricularia pubescens (Lentibulariaceae) and Drosera indica (Droseraceae).
