Tegenaria saeva and T. gigantea. vary geographically in Britain. To understand fully their underlying causes requires knowledge of species ranges in the past. Here. information from five sources: (a) historical distribution maps based on county and vice county lists; (b) a re-examination of museum and other collections; (c) catalogues of museum specimens recently re-examined by experts; (d) scrutiny of the literature; (e) a request published in a Wildlife Trust magazine, is used to determine historical distribution patterns. It is shown that the northern limits of both species have generally increased through time and that this phenomenon is not a result of variable recorder effort. In the south of England. the species boundary in Dorset has apparently been stable for at least a century. The ecological and evolutionary implications of these results are discussed.}, keywords = {/ ] [United Kingdom / Britain / ]., Ecology, Eurasia, Europe, Evolution, interactions / ] [Ecology / / ] [Zoogeography / Historical distribution, Land zones, Palaearctic region, Tegenaria gigantea, Tegenaria gigantea (Araneae)., Tegenaria saeva (Araneae)., Tegenaria saeva [Evolution / Evolutionary, Zoogeography}, isbn = {0524-4994}, url = {://ZOOREC:ZOOR14508050419}, author = {Oxford, G.

Members of this group of large house spiders have overlapping distributions in western Europe and hybridize with each other to a variable degree. The close relatedness of all three species was supported by all analyses. T. saeva and T. gigantea are more closely affiliated than either is to T. atrica. Haplotypes clearly assignable to T. gigantea were also present in many specimens of T. saeva, suggesting asymmetrical introgression of mtDNA from T. gigantea into T. saeva. Molecular clock calibrations (CO1) suggest that deeper divisions within the genus Tegenaria may be in excess of 10 million years old, and that the evolutionary history of the T. atrica group has been moulded by Quaternary glacial-interglacial cycles.}, keywords = {[Molecular genetics / / ] [Hybridization / / Introgression evidence], [Phylogeny / Molecular phylogeny / ] [Biochemical variation / / ]., Biochemistry, Evolution, Genetics, mtDNA sequences / Introgression evidence \& phylogenetic implications], Systematics, Tegenaria atrica, Tegenaria atrica (Araneae)., Tegenaria gigantea, Tegenaria gigantea (Araneae)., Tegenaria saeva (Araneae)., Tegenaria saeva [Nucleic acids /, Variation}, isbn = {0024-4066}, url = {://ZOOREC:ZOOR14004021926}, author = {Croucher, P.
