Research interests
My research focusses on the interplay between plants and animals and their interactions with the abiotic and biotic environment. In particular, I study the dynamics of temperate and tropical forest ecosystems across elevational and land use gradients. In one of my research themes, I study the dispersal of seeds by animals, which is one of the key ecosystem services for natural forest restoration. I combine a diverse set of methods, ranging from field observations and experiments to molecular and meta-analytic approaches and advanced statistical modelling to project the response capacity of plants to land use and climate change.
In one of my projects, we examine seed dispersal pattern by nutcrackers (Nucifraga caryocatactes) along environmental gradients in alpine pine forests. We investigate, how seed deposition by nutcrackers and other biotic and abiotic drivers relate to the potential of Swiss stone pine seedlings (Pinus cembra) to establish.

In other projects in the tropical Andes, we study how abiotic and biotic filters affect the regeneration of plants of various life history traits across an elevational and disturbance gradient in Southern Ecuador. In Northern Ecuador, we study how seed dispersal networks (birds and rodents) reassemble across a forest disturbance gradient in the Chocó region.

RESEARCH INTERESTS
My primary research interest is to understand the interactions between vegetation, atmosphere and humans. Therefore, I develop and apply different modelling approaches, particularly process-based dynamic vegetation models (DGVMs), to simulate ecosystem dynamics, biogeochemical cycles, and diversity. Vegetation models are coupled with land use models to help us understand how climate change and land-use influence ecosystems, diversity and ecosystem services, and to help develop strategies for the sustainable use of natural resources.
