Title: The characteristics of community structure of ground-dwelling spider in the different habitats from Urumqi
Abstract: The relationships between community structure and different habitat types of ground-dwelling spider were investigated using small plot direct searching method to assess the impact of land-use type and habitat management on spider community structure in six different habitat types(namely,natural forest,shelter forest,orchard,vegetable field,grassland and residential area) in April,July and September in 2008 in Urumqi,Xinjiang,southwestern China.A total of 2195 individual spiders were collected from various habitats,and representing 28 families,47 genus,71 species.In generally,the dominant families collected from the whole area of ground-dwelling spider are Lycosidae,Salticidae,Araneidae,and Thomisidae,which accounted for 54.94% of total species collections.The common families are Philodromidae,Theridiidae,Dolomedidae,Uloboridae,Agelenidae,Pholcidae,and Linyphiidae collected from that area,they account for 34.52% of total species collections,the other 7 families are belonged to the rare groups,and they only accounted for 4.54%% of total species collections.There are significant differences between the individual numbers and group numbers in the six different habitats and different seasons(P0.05),the sequences of individual number are natural forestgrasslandshelter forestresidential areaorchardvegetable field,it occurs the highest number in Summer,and the lowest in Autumn.The abundance of ground-dwelling spider in the natural forest are significantly higher than the remaining five types of habitats. The above results indicat that the ground-dwelling spider of Urumqi area are rich in natural resources and community,different habitat types have a strong impact on ground-dwelling spider composition and distribution pattern,the plant community abundance and anthropogenic disturbance are the main impact factors of the community structure of ground-dwelling spiders.
