Elevational gradients are ideal for studying geographic variation in the distribution and abundance of organisms corresponding to predictable variation in climatic factors. This study provides a broad-scale assessment of variation in distribution patterns of foliage-dwelling arthropod orders along elevational gradients located across an extensive precipitation gradient in the Himalayas. Relative abundances of foliage-dwelling arthropods were estimated from 16 sites during the summer months. Abundances declined significantly from east to west and peaked at intermediate elevations along elevational gradients, corresponding with trends in climatic variables.
