FUNCTIONAL DIVERSITY OF AQUATIC MACROINVERTEBRATES ALONG A STREAM-SIZE GRADIENT IN THE COLORADO ROCKIES

While the pattern of aquatic macroinvertebrate communities along a size gradient has been examined in past studies, it is usually in the context of the river continuum, moving along a stream network from the headwaters to large rivers. This is problematic because many additional aspects of streams are changing along this gradient. The pattern of how macroinvertebrate communities change along a subtle size gradient is not well known, especially in terms of functional traits like functional feeding group and habitat preference. Macroinvertebrate communities from 15 first and second order streams in the Cache la Poudre watershed in the Colorado Rockies that differed in size were sampled and analyzed to see how taxon and functional diversity differs predictably along these gradients.
