AQUATIC INSECT FUNCTIONAL DIVERSITY ALONG CANOPY COVERAGE, ELEVATION AND WATER TEMPERATURE GRADIENTS IN ROCKY MOUNTAIN STREAMS
Organismal traits determine how species perform and contribute to ecosystem functioning. Functional diversity indexes quantifies the value and range of these traits, which provides a mechanistic framework to understand community productivity and resilience to perturbations or invasion. We applied a multifaceted framework to quantify three primary components of functional diversity of stream insects along environmental gradients of canopy coverage, water temperature and elevation across the Rocky Mountain Streams of Colorado. We used Functional Richness (FRic), Functional Evenness (FEve) and Functional Divergence (FDiv) indices to test for significant differences in aquatic insect functional diversity in 24 small streams in three adjacent catchments, spanning an elevational range of ca. 2000–3500 m. Our results showed that only FRic differs significantly with elevation, and that the pattern of change remains constant across catchments. Traits related to development, habit, voltinism and adult dispersal ability showed the highest sensibility to changes in the environment, particularly to water temperature changes. Our findings provide independent information concerning position and relative abundances of species in a multidimensional functional space, and allow for inferences on patterns of aquatic insect functional beta diversity in mountain streams.
