Spatial scale affects community concordance among fishes, benthic macroinvertebrates, and bryophytes in streams.
Owing to the lack of information about the distribution patterns of many taxonomic groups, biodiversity conservation strategies commonly rely on a surrogate taxa approach for identifying areas of maximum conservation potential. Macroinvertebrates or fish are the most likely candidates for such a role in many freshwater systems. The usefulness of the surrogate taxa depends largely on community c...
متن کاملEvaluating of VIC-3L Land Surface Model for Simulation of Stream Flow of Gharesou watershed
Land-surface models are widely used to simulate and predict the movement of momentum, energy, and matter between the biosphere and the atmosphere at local, regional and global scales. In this study, in order to evaluate the performance of this model in daily simulation of discharge in Gharesou watershed, using a spatial resolution of 0.125 degrees, satellite imagery and global databases to prov...
متن کاملAPPLIED ISSUES Amphibians as metrics of critical biological thresholds in forested headwater streams of the Pacific Northwest, U.S.A
1. Amphibians are recognized both for their sensitivity to environmental perturbations and for their usefulness as cost-effective biometrics of ecosystem integrity (=system health). 2. Twenty-three years of research in headwater streams in the Klamath-Siskiyou and North Coast Bioregions of the Pacific Northwest, U.S.A., showed distinct patterns in the distribution of amphibians to variations in...
متن کاملInfluence of spatial resolution on assessing channelization impacts on fish and macroinvertebrate communities in a warmwater stream in the southeastern United States.
The choice of spatial and temporal scale used in environmental assessments may influence the observed results. One method of assessing the impact of stream habitat alterations involves the comparison of response variables among treatment categories (i.e., impacted and unimpacted sites). The influence of spatial resolution on patterns of response variables among treatment categories in assessmen...
