Objective

Spiders (Araneae) are one of the largest orders of animals with over 40,000 described species. They are widely distributed in all geographical areas, including the High Arctic, and present in all terrestrial habitats. There are fragmentized data split in several dozens of publications of different languages about spiders in the High Arctic, where they represent the major predator group in mesofauna. There are many uncertainties in taxonomy, distribution, and biology of Arctic spiders. The main goals of this project are as follows: 1) To summarize all taxonomic, biological and distributional data on spiders (about 140 species) inhabiting the High Arctic Islands. 2) To compare distribution of High Arctic species with microclimatic conditions on Arctic Islands. 3) To estimate the effect of the Global Change on arctic spiders. 4) To trace the origin of High Arctic fauna on the basis of morphological and molecular studies of species with arcto-alpine disjunctive ranges. Spiders were chosen because they are unspecialized predators (not depending on specific plants, host animals or litter properties like phytophages, parasites or saprophages) and therefore optimal for zoogeographical studies related to the climate. Spiders are also good models because they can be easily identified and species relationships can be traced by similarity of very complicated species-specific copulatory organs. On the basis of this study we will prepare a monographic synopsis on Arctic Island spiders which will include: 1) identification key, 2) taxonomic survey, 3) review of biological data known for certain species, 4) zoogeographical analysis of Arctic spiders and detail comparison with zoogeographical pattern observed in other well-studied terrestrial arthropods like ground and leaf beetles, some gamasid and oribatid mites. Many taxonomic and zoogeographical separate publications will be compiled during the study. In this work we will use new approaches (innovations) in the study of the faunogenesis, which can also be used by students in other fields. 1) Involving original estimation (developed by us) microclimatic data (possible highest sum of mean-positive temperatures of soil surface depending on continentality). 2) Molecular data has not been used earlier for tracing origin of arcto-alpine disjunctions (source can be Alps or Siberia-Alaska) and 'calibrating' molecular clocks by studying species with same geographical disjunctions.
