Data: Elevational and seasonal differences in macroinvertebrate community structure in alpine streams

We tested the hypothesis that benthic macroinvertebrate community structure in alpine streams responded to spatial-temporal changes in thermal regimes and environmental factors across an elevation gradient. Differences in macroinvertebrate community structure between elevations were seen with fewer families of EPT above the tree line, than it, suggesting that the larger annual temperature range above the tree line is stressful to macroinvertebrates and pose risks from climate change.
