KW - Tegenaria saeva [Evolution / Evolutionary KW - Zoogeography AB - Current relative distributions and evolutionary inter-actions of two species of large house spiders. 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.

KW - Tegenaria saeva [Nucleic acids / KW - Variation AB - The relationships between the three members of the Tegenaria atrica group (T. atrica, T. saeva and T. gigantea) were examined with DNA sequence data from mitochondrial CO1, 16S rRNA, tRNAleu(CUN) and ND1 genes. 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.

Predicting when and where species are likely to experience inter-specific interactions as a result of climate change may be as relevant to understanding their evolutionary futures as predicting responses to physical environmental variables. 2. In this paper, models built using data for the distributions of two species of large house spider, Tegenaria saeva and T. gigantea (Agelenidae), from relatively long-established parts of their ranges are used to predict species overlap in a region of more recent range expansion. 3. Generalised linear models (GLMs) are used to identify the key environmental variables associated with the distributions of the spider species in an east[long dash]west band across central Britain. Using this model, the distributions of the two species both north and south of the central band are predicted and tested for how closely they matched observed distributions, and thus whether environmental factors are a sufficient explanation for current distribution patterns in England and Wales. 4. Results demonstrate that predictions of both species distributions and overlap in the south region are almost as good as in the model-building zone, but that predicted distributions in the north are no better than random. Here either climate is of no importance in determining species distributions or, perhaps more likely, the system is still in a state of flux and currently reflects the stochasticity of recent colonisation. 5. Further long-term monitoring of the populations may allow discrimination between alternative hypotheses that could explain the current mismatch between climate and species' distributions VL - 2 SN - 1752-458X UR - ://ZOOREC:ZOOR14511070670 N1 - ZOOR14511070670 ER -
