Population dynamics and conservation of large carnivores in anthropogenic landscapes
Large carnivores face significant challenges in human-dominated landscapes. We use individual-based models to analyse their population genetics, their population dynamics and their viability.

Several wildlife species face big challenges persisting in human-dominated landscapes. We use an individual-based model on a spatially-explicit basis to analyse their population dynamics, viability and connectivity as well as aspects of population genetics. Our aim is to support the decision-making process of conservation planning when it comes to wildlife management that foster long term viable populations in a landscape dominated by humans.
For example, one of our focus species is the biggest European cat species, the Eurasian lynx (Lynx lynx). The genetic viability of the reintroduced populations of this large carnivore has been called into question due to the weak genetic exchange. In this project we develop an existing population model to include individual genetics for testing conservation management scenarios in order to reveal the potential for enhancing the genetic viability of a Central European meta-population.
Further case studies are conducted on the wolf in Europe and the jaguar in Central America.
