Abstract

Populations of the carabid beetle, Pterostichus melanarius, will be sampled at national, county, farm and field spatial scales from differently fragmented landscapes. Their genetic structure will be analysed using 6-12 microsatellite loci in order to estimate the extent of current gene flow between the populations. Sequence variation at the COI region of mtDNA will be used to examine historical divergence at the larger sampling scales. Field boundary permeability, determined from mark-recapture studies, will be used to parameterise dispersal models to generate probabilities of exchange of individuals between populations as a function of time and distance. The model based estimates of dispersal will be compared with those inferred from population genetic structure, and the use of genetic information alone to estimate the dispersal powers of other species will be explored. (Joint with grant D09448).
