Genetic consequences of forest fragmentation for a highly specialized arboreal mammal--the edible dormouse.

Habitat loss and fragmentation represent the most serious extinction threats for many species and have been demonstrated to be especially detrimental for mammals. Particularly, highly specialized species with low dispersal abilities will encounter a high risk of extinction in fragmented landscapes. Here we studied the edible dormouse (Glis glis), a small arboreal mammal that is distributed throughout Central Europe, where forests are mostly fragmented at different spatial scales.

Isolation of ten tetranucleotide microsatellite loci in the Northern Wheatear (Oenanthe oenanthe).

We isolated 10 polymorphic microsatellite DNA loci from the Northern Wheatear (Oenanthe oenanthe) and optimized these for future studies in population genetics and behavioural ecology. The loci were screened for polymorphism using 107 individuals from one population in Germany. The primers amplified loci with high numbers of alleles ranging from two to 20 alleles per locus.

Isolation of 10 tetranucleotide microsatellite loci in the blackcap (Sylvia atricapilla).

We isolated 10 polymorphic microsatellite DNA loci from the blackcap (Sylvia atricapilla) and optimized them for future studies of population differentiation in populations with different migration strategies in southwestern Germany. The loci were screened for polymorphism using 178 individuals from two populations in Germany and Spain. The primers amplified highly variable loci characterized by two to 19 alleles per locus and their observed and expected heterozygosities range from 0.
