The spiders were collected from two meadow ecosystems differently polluted with metals (Olkusz and Pilica, southern Poland). Under stress conditions, P. lugubris had fewer apoptotic cells in the midgut glands than A. labyrinthica. In P. lugubris from both sites, the observed increase in the percentage of metallothionein and Hsp70-positive cells, simultaneous with intensification of superoxide dismutase and catalase activity, suggests an anti-apoptotic function of those proteins in representatives of wandering spiders. In the midgut glands of A. labyrinthica, heat shock and dimethoate increased the number of Annexin V-positive cells as well as the amounts of mitochondria with low transmembrane potential ([DELTA][PSI]m) versus the control. The changes in the percentage of MT and Hsp70-positive cells in funnel web spiders were less than in wolf spiders. The absence of change in SOD and CAT activity in A. labyrinthica shows that the participation of those enzymes in antioxidant reactions is minimal in this species. [copyright] 2005 Elsevier Inc.

The entire sample from the 26 trapping periods consisted of 6753 adult spiders of 100 species. The overall abundance and species richness was highest in the early season, May and June. Seasonal spider catch was not correlated with fluctuations in temperature. but was negatively correlated with rainfall. Nine of the ten abundant species ( gtoreq 2\% of the sample each) belonged to the family Linyphiidae (sensu lato) and one to the family Agelenidae. Macrargus rufus (Wider) was the most abundant species comprising approximately 1/3 of the sample followed by Lepthyphantes alacris (Blackwall) (17\% of the sample). The activity peaks of the ten abundant species were usually short, only a few weeks, and occurred in the early and mid-season, May-July. Only L. alacris was collected every trapping period.

Our investigation of the influence of pasturage and grassland burning upon the abundance of insects and spiders on the host plant, Sophora flavescens indicated the following facts: (1) Collected from the host plant of this butterfly were 10 families, 19 species of spider. Thomisid spiders were most aboundant, followed by araneid spiders. (2) A number of spiders preyed on this butterfly: Linyphia radiata (Linyphiidae), Agelena limbata (Agelenidae), Neoscona adianta (Araneidae), Tibellus tenellus (Philodromidae), Xysticus ephippiatus (Thomisidae), Misumenops tricuspidatus (Thomisidae), Carrthotus xanthogramma (Salticidae).

Dominant species were larvae of this butterfly, Formica japonica (Formicidae) and Camponotus japonicus (Formicidae). (4) Under the non-pasturage or non-grassland burning, the population of larvae of this butterfly, F japonica and C. japonicus decreased markedly. On the other hand, the spider density of the field under the non pasturage or non fire burning was higher than that of the field under the pasturage and grassland burning, especially Thomisidae.

Levels of sequence divergence obtained from the mitochondrial gene, cytochrome oxidase I, dated to the Pleistocene, eliminating Rocky Mountain orogeny as a cause of diversification, as orogeny ended 4 million years ago. The results of phylogenetic and network analyses showed the presence of three geographically defined clades, which were consistent with the presence of at least three glacial refugia: (i) east of the Rocky Mountains; (ii) between the Rocky Mountains and Sierra Nevadas; and (iii) west of the Sierra Nevadas. In addition, populations within the Rocky Mountains exhibited significantly lower genetic diversity than populations east of the Rocky Mountains and the haplotypes found within the Rockies were a subset of eastern haplotypes. These patterns suggest that a post-Pleistocene range expansion occurred out of an eastern glacial refugium into the Rocky Mountains. Examination of phylogeographical studies of other North American desert taxa indicated that mountain building explained diversification patterns more effectively for some taxa but Pleistocene climate change was more important for others, including A. aperta.}, keywords = {Abiotic factors, Agelenopsis aperta (Araneae): [Fossil]., Agelenopsis aperta [Enzymes / Cytochrome oxidase I mtDNA gene sequence /, Biochemistry, Caenozoic, Diversification patterns, diversification patterns] [North America / / ] [Pleistocene / / ]., Evolution, Genetics, Geological time periods, influence of climatic vs geological, influences] [Molecular genetics / / ] [Population genetics / /, Land zones, molecular evidence] [Biochemical variation / / Cytochrome oxidase I, mtDNA sequences] [Climate and weather / / Influence on diversification, Nearctic region, patterns] [Geophysical events / / Geological influences on, Physical factors, Proteins, Quaternary, Variation}, isbn = {0962-1083}, url = {://ZOOREC:ZOOR14101006872}, author = {Ayoub, Nadia A. and Riechert, Susan E.} } @article {14, title = {Predicting range overlap in two closely related species of spiders}, journal = {Insect Conservation and Diversity}, volume = {2}, year = {2009}, note = {ZOOR14511070670}, month = {2009}, pages = {135-141}, abstract = {1. 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{\textquoteright} distributions}, keywords = {[Climate and weather / Climate change / ] [England / / distribution], [Wales / / ]., Abiotic factors, Eurasia, Europe, Generalised linear models / range overlap of species prediction], Land zones, Palaearctic, Physical factors, region, Techniques, Tegenaria gigantea, Tegenaria gigantea (Araneae)., Tegenaria saeva (Araneae)., Tegenaria saeva [Mathematical techniques /, United Kingdom}, isbn = {1752-458X}, url = {://ZOOREC:ZOOR14511070670}, author = {Anderson, Barbara J. and Bai, Yixuan and Thomas, Chris D. and Oxford, Geoff S.} } @article {7, title = {Feeding and growth of Coelotes atropos (Araneae, Agelenidae) at low temperatures}, journal = {Journal of Arachnology}, volume = {9}, year = {1981}, note = {ZOOR11800036248}, month = {1981}, pages = {327-330}, abstract = {Feeding by C. atropos decreases sharply at and below 6.degree.
