Lay Summary (Englisch)

Lay summary
Human impacts on landscapes, and the concomitant fragmentation of natural populations, are among the most important issues in conservation biology. It is the responsibility of ecologists to help delineating the conditions for population survival in fragmented habitats, and the sensitivity of such conditions to relevant features of species and landscapes. The problem of fragmentation must be considered in terms of both demography and genetics, since both interact to drive fragmented populations into extinction vortices. It is also crucial that theoretical and empirical aspects of such issues be considered simultaneously, if one wants to develop and validate useful monitoring tools, and base management strategies on scientific grounds. The present project consists of two interconnected parts, one dealing with theoretical modeling, and the other with empirical applications. Through simulations we evaluate the effects of landscape structure on the demographic and genetic properties of metapopulations that are important for their viability, and investigate how the individual properties of different patches (size, quality, connectivity) affect their contribution to the viability and effective size of the metapopulation they belong to (i.e., measure patch values in different currencies). Demographic and genetic aspects are compared and contrasted, in order to delineate zones of potential conflicts between different requirements. The empirical part aims at developing monitoring tools and evaluating parameter values required to calibrate the models. This part is based on two contrasted model species (a mammal and an amphibian) living in highly structured environments, and is aimed at delineating better management guidelines for fragmented populations
