For completion previously published data from 160 roe deer from 7 provenances in Austria were also included in the present analysis. With a total p proportion of polymorphic loci of 30 a mean p of SD 2 and a mean H expected average heterozygosity of SD Capreolus capreolus is one of the genetically most variable deer species yet studied. Relative genetic differentiation among populations was examined. About 10 of the total genetic diversity is due to genetic diversity between demes. Absolute genetic distances are typical for local populations throughout the area except in Hungary where the D-values with all other provenances suggest an emerging subspecies. This differentiation may have been caused by the completely fenced borders between Austria and its neighbouring countries to the east. Except in Hungary the pattern of allele frequencies reflects the patchy distribution of roe deer populations and periodical bottlenecking caused by the breeding behaviour and or overhunting and recolonization rather than a large scale geographic diversification. The various aspects of genetic variability and differentiation in roe deer are discussed in comparison to a related species with a rather different strategy of adaptation the red deer. .
