英文摘要	Climate change will likely increase habitat loss of endemic tree species and drives forest conversion in mountainous forests. Elevation gradients provide the opportunity to predict possible consequences of such changes. While species compositions of various taxa have been investigated along elevation gradients, data on trophic changes in soil-dwelling organisms are scarce. Here, we investigated trophic changes of the Collembola communities along the northern slope of Changbai Mountain, China. We sampled Collembola in primary forests at seven elevations (800-1700 m asl). We measured individual body lengths and bulk stable isotopes on species level. We further categorized Collembola species into life forms. The community-weighted means of Delta 15N and Delta 13C values as well as minimum Delta 15N values and isotopic uniqueness of Collembola communities increased with increasing elevation, while the range of Delta 15N values decreased. Maximum and minimum of Delta 13C values differed between elevations but showed no linear trend. Further, Delta 15N values of Collembola species occurring across all elevations increased with elevation. Changes in Delta 15N values with elevation were most pronounced in hemiedaphic species, while Delta 13C values increased strongest with elevation in euedaphic species. Delta 15N values increased with decreasing body size in hemiedaphic and euedaphic species. Overall, the results suggest that Collembola species functioning as primary decomposers at lower elevations shift towards functioning as secondary decomposers or even predators or scavengers at higher elevation forests. The results further indicate that access to alternative food resources depends on Collembola life form as well as body size and varies between ecosystems.
