Research interests:


  • Conservation Biology of reptiles and amphibians
  • Distribution patterns of individuals and populations in fragmented landscapes, and related ecological processes
  • Effects of habitat fragmentation at different spatial scales
  • Individuals and populations reaction to habitat loss.

Research project:

Differential sensitivity to fragmentation of the eastern green lizard (Lacerta viridis) at the core and periphery of its range

Zeitraum: 2014 - 2017

The sensitivity to habitat fragmentation of a given population depends on the degree of habitat specialization of the species. The Kühnelt principle (Kühnelt, 1965) states that the range of colonizable habitats is wider at the core of the distribution range of a species where living conditions are optimal, whereas at the periphery conditions are impairing. Then, populations of the same species living at the core are euryoecious or habitat generalist, and stenoecious or habitat specialist at the edge. In this project I investigate the sensitivity to habitat fragmentation of populations of the eastern green lizard (Lacerta viridis) in relation to their occurrence as habitat generalist in the core of their distribution range (Bulgaria) or as habitat specialist in the northern periphery (Germany, Czech Republic). I look for differences between core and periphery related to the spatial scale and/or level of biological organization (individuals, populations ) at which habitat fragmentation has an effect. I hypothesize that populations of Lacerta viridis are more sensitive to habitat fragmentation at the periphery of the distribution range, at both landscape scale (populations) and patch level (populations, individuals), and that the effects of habitat fragmentation are present already at smaller spatial scales in the periphery compared to the core. The objective of this project is to better understand the effects of habitat fragmentation in order to apply effective conservation measures for the protection of Lacerta viridis in Europe.
