TRANSBOUNDARY ASSESSMENT OF BENTHIC MACROINVERTEBRATE DIVERSITY PATTERNS IN TRIBUTARIES OF THE RED RIVER BASIN
The Red River Basin is a key transboundary watershed shared by Canada and the USA. Tributary monitoring efforts have been ongoing for over a decade in the three main jurisdictions that comprise the Basin (Manitoba, Minnesota, North Dakota), but there has not been a transboundary assessment of the available data. We initiate this process by conducting a basin-wide, biogeographical assessment of stream benthic macroinvertebrate assemblages using data from over 1000 stream samples. Initial assessments include analyses to determine geographical patterns of alpha and beta-diversity across the region and among six major ecoregions. Preliminary results indicate a significant amount of homogeneity in assemblage composition, possibly a result of the widespread agricultural activity in much of the Red River Basin. Further assessments will be conducted to test hypotheses about the role of land use on diversity patterns and to link benthic invertebrate communities with stream water chemistry and habitat measures. Furthermore, we will explore the spatial relationship among communities and its influence on taxonomic turnover among sample sites. Findings will provide critical insight towards improved collaborative management of tributaries throughout the Red River Basin.
