摘要: Aquatic ecosystems and their fauna are vulnerable to a variety of climate-related changes. Benthic macroinvertebrates used frequently by water-quality agencies monitor the status aquatic resources. We several regionally distributed state bioassessment data sets analyze how climate change might influence metrics define ecological condition streams. Many widely used, taxonomically based were composed both cold- warm-water-preference taxa, differing responses these temperature-preference groups climate-induced changes in stream temperatures could undermine assessment condition. Climate responsiveness trait varied among states ecoregions, but generally sensitive changing temperature conditions. Temperature sensitivity taxa organic pollution moderately significantly correlated. Therefore, selected for assessments because disturbance or conventional pollutants also temperature. explored feasibility modifying partitioning components on reduce likelihood that would confound impairment from other causes facilitate tracking climate-change-related taxon losses replacements.
