Conservation and management of populations in a fragmented forest landscape. Behavioural ecology meets population genetics
The effects of habitat loss and fragmentation on the genetic structure and vulnerability of populations strongly depend on the behaviour of a particular species. In this thesis, I examined the effects of forest fragmentation on genetic population structure with the aim of identifying and evaluating the different genetic and behavioural factors important for species conservation and management o...
متن کاملConservation of Fragmented Populations
In this paper we argue that landscape spatial structure is o f central importance in understanding the effects o f f ragmentat ion on populat ion survival Landscape spatial structure is the spatial relationships among habitat patches and the matr ix in which they are e m ~ l d e ~ Many general models o f subditrlded populat ions make the assump. tions that (1) all habitat patches are equivalent...
متن کاملConservation Ecology: Detecting Critical Scales in Fragmented Landscapes
We develop methods for quantifying habitat connectivity at multiple scales and assigning conservation priority to habitat patches based on their contribution to connectivity. By representing the habitat mosaic as a mathematical "graph," we show that percolation theory can be used to quantify connectivity at multiple scales from empirical landscape data. Our results indicate that connectivity of...
متن کاملEffective seed dispersal across a fragmented landscape.
The role of seed dispersal in maintaining genetic connectivity among forest fragments has largely been ignored because gene flow by pollen is expected to predominate. By using genealogical reconstruction, we investigated gene flow after establishment of seeds in a wind-pollinated, wind-dispersed tree. Our data show that seed dispersal is the main vector of gene flow among remnants and that long...
متن کاملAchieving climate connectivity in a fragmented landscape.
The contiguous United States contains a disconnected patchwork of natural lands. This fragmentation by human activities limits species' ability to track suitable climates as they rapidly shift. However, most models that project species movement needs have not examined where fragmentation will limit those movements. Here, we quantify climate connectivity, the capacity of landscape configuration ...
