摘要: Spiders of the timberline on Alp Flix (Switzerland, Canton Grisons, 1960 m) were collected between June 2002 and May 2004 around stand-alone Norway spruce trees (Picea abies) by means pitfall traps, funnel frame litter sampling, branch eclectors, restricted canopy fogging, beating, sweep netting hand sampling. 93 species recorded, four them endemic to Alps another six European mountain system. Five are new Grisons: Evansia merens, Meioneta innotabilis, Moebelia penicillata, Obscuriphantes obscurus Agroeca proxima. Most can be classified as forest or open-land dwellers that contribute equally diversity, only few generalists. 13 % (27 individuals) winteractive. It is shown at alpine offer a broad range habitats for high number spider species. This should considered in future conservation research efforts. Phenologies certain included.
