AbstractGenetic variation in chromosomally polymorphic Sicista subtilis complex and related Sicista betulina species group was analysed using two mitochondrial markers (COI and Cytb). The S. subtilis group is shown to include six lineages, five of which correspond to species currently recognized based on cytogenetic and genetic data: Sicista nordmanni, Sicista trizona, S. subtilissensu stricto, Sicista severtzovi and Sicista cimlanica. A previously unknown genetic lineage of S. subtilis was found in the North Caucasus. The existence of two divergent lineages within Sicista strandi is supported. It is suggested that the speciation rate in Sicista was strongly affected by rapid chromosomal evolution.

Several evolutionary hypotheses help explain why only some species adapt readily to new conditions and expand distributions beyond borders, but there is limited evidence testing these hypotheses. In this study, we consider patterns of neutral (microsatellite) and quantitative genetic variation in traits in three species of Drosophila from the montium species group in eastern Australia. We found little support for restricted or asymmetrical gene flow in any species. In rainforest-restricted Drosophila birchii , there was evidence of selection for increased desiccation and starvation resistance towards the southern border, and a reduction in genetic diversity in desiccation resistance at this border. No such patterns existed for Drosophila bunnanda , which has an even more restricted distribution. In the habitat generalist Drosophila serrata , there was evidence for geographic selection for wing size and development time, although clinal patterns for increased cold and starvation resistance towards the southern border could not be differentiated from neutral expectations. These findings suggest that borders in these species are not limited by low overall genetic variation but instead in two of the species reflect patterns of selection and genetic variability in key traits limiting borders.
