WHERE TO GO FROM HERE? AQUATIC INSECT FUNCTIONAL AND TAXONOMIC DIVERSITY RESPOND TO CHANGES IN CANOPY, ELEVATION AND WATER TEMPERATURE IN ROCKY MOUNTAIN STREAMS
Growing levels of human-induced changes on mountainous streams around the globe, demand for an understanding of how species diversity and ecosystem function are affected by increasing water temperature and loss of riparian coverage along environmental gradients. Organismal traits determine how species perform and contribute to ecosystem functioning. Functional diversity 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 functional diversity of stream insects along gradients of canopy coverage, water temperature and elevation across the Rocky Mountain Streams of Colorado. Our results showed that organismal traits related to development, habit, voltinism, and adult dispersal ability are highly correlated to environmental fluctuations, particularly to water temperature changes over 1°C in areas with an open canopy (less than 60% coverage). These findings support the understanding that small tributary streams collectively exhibit high beta diversity; and that taxonomic and functional richness declines with elevation in headwater mountain streams. Habitat heterogeneity, changes in water temperature, and increased pressure on dispersal traits between isolated communities; contribute to sustaining large biotic heterogeneity among small montane streams.
