ASSEMBLAGES OF SPIDERS ON MODELS OF SEMI-ARID SHRUBS

摘要: Abstract Many environmental factors influence the composition of animal assemblages. For spider assemblages, plant architecture is an important variable. Here we examine effects various architectural attributes by using models shrubs in which control branch orientation (horizontal or vertical) and height above ground (0, 10, 40 cm). Guild membership, based on hunting strategy (jumpers, pursuers, ambushers, trappers), was used to characterize Five replicates six treatments (two orientations three heights) were randomly placed a 60 m 50 grid among big sagebrush shrub-steppe habitat sampled at 3 week intervals from July–October 1997 1998. ANOVA demonstrate that not only do single variables distribution spiders but also interaction distribution. Differences assemblages result differ...
