From processes to systems - predicting global change impacts on ecological networks

Life on earth is interconnected. Plants and animals interact with each other and with their environment and are therefore linked in tight networks consisting of direct and indirect flows of energy and information. External stressors to ecosystems, such as those caused by global change, affect not only the individual, but the entire system in which they are integrated. Therefore, we need to understand (1) how these systems are interconnected, (2) what mechanisms constitute their stability, and (3) how changes in individual physiology and performance cascade through these systems, ultimately influencing their stability and, more importantly, their ecosystem services to the planet and to us humans.

Movement is a fundamental process of most organisms that enables interactions with their environment and other species. It allows accessing resources, searching for mating partners, connecting spatially separated habitats, and seeking shelter from predators or climatic stress. While global change drivers such as climate warming or habitat fragmentation directly affect the physiology of animals and thus their fundamental needs, movement realizes these changes in interactions and ultimately in entire networks and ecosystems. My main research questions are therefore how we can use information about animal behavioral and physiological responses to global change to predict the consequences for ecological communities and their provision of ecosystem services to humans. I use both empirical and theoretical approaches to answer this question. This type of empirically grounded theory helps make large-scale predictions from small-scale experiments on fundamental processes.
