Research Interests

My main interests are to understand the functional linkages between species and trophic levels and how these processes determine large scale ecological patterns. Species interactions with their environment and with each other, including plant-animal systems and above- and belowground linkages, has been a theme of my research for the last years. Currently, I focus on the effects of temperate tree diversity and composition for ecosystem functioning and multitrophic interactions. The main objectives are to quantify the functional significance of tree diversity for productivity and resistance against pests (e.g. herbivores, pathogens) based on data obtained from experimental tree plantations in Germany (the BIOTREE experiment) and from National Forest Inventories (NFI).

BACCARA - Biodiversity and Climate Change, a Risk Analysis

BACCARA’s main goal is to build scientific foundations for developing tools allowing forest managers and policy makers to evaluate risk of European forest biodiversity and productivity loss under climate change. The scope of BACCARA encompasses forest composition at multiple trophic levels, i.e. assemblages of forest symbionts (mycorrhiza), producers (keystone tree species), consumers (herbivores and pathogens) and their predators. The concept of the project is to construct a 3-dimensional risk assessment model linking climate change, functional diversity, and forest productivity.

BACCARA is a project receiving funding from the European Community's Seventh Framework Programme (FP7/ 2007-2013) under the grant agreement n° 226299
