Fränzi Korner-Nievergelt | Research interests
Understanding the population dynamics of wildlife in a changing world is the motivation of my research. I combine ecological, statistical, and mathematical models to study ecological processes that are usually difficult to observe in the wild. Focusing on rare and sensitive species, I aim to summarize current knowledge based on data and expert opinions, to assist making of sustainable decisions in management and nature conservation.
In my research, I help identifying key demographic parameters and understanding how these parameters are shaped by the environment. For example, I made models on movements and survival of migratory animals based on recoveries of marked animals found dead, or based on GPS or geolocation data as well as on stable isotope and parasite data. Recently, I also modelled the composition of winter populations of hunted species, with the aim to inform hunting regulation.
Currently, I concentrate on methods for integrating economic, societal, and ecological costs and benefits of decisions in nature conservation. Underlying all of my work as a statistician and researcher is the aim to assess uncertainty and to help communicating uncertainty to scientists, conservation managers, and decision makers.
