Relationships of fish assemblages, instream physical habitat, and landscape characteristics of wadeable Iowa streams
Fish assemblages play a key role in stream ecosystems, and play a crucial role in the assessment of stream health. Physical habitat is a key component of stream ecosystems and plays a major role in determining biotic assemblages and stream integrity. There is increasing recognition of the role landscape factors play in determining biotic assemblages and stream integrity. Landscapes in Iowa and ...
متن کاملFish species of greatest conservation need in wadeable Iowa streams: status, habitat associations, and effectiveness of species distribution models
Effective conservation of fish species of greatest conservation need (SGCN) requires an understanding of species-habitat relationships and distributional trends. Thus, modeling the distribution of fish species across large spatial scales may serve as a potentially valuable tool for conservation planning. Our goals were to evaluate the status of 10 Iowa fish SGCN in wadeable Iowa streams and tes...
متن کاملChapter 8: Coldwater Fish in Wadeable Streams
Fish fauna of small coldwater streams of North America typically include trout and salmon, sculpins, minnow, sticklebacks, suckers, or lampreys (Hocutt and Wiley 1986). Standard sampling protocols provided herein apply primarily for trout and salmon because of their sport and commercial values (Johnson et al. 2007). As interest in nonsalmonid species grows, further development of sampling metho...
متن کاملA Rapid Physical Habitat Assessment of Wadeable Streams for Mixed-Land-Use Watersheds
Mitigating stream and river impairment is complex, particularly in mixed-land-use watersheds given the likelihood of integrated responses of stream restoration to coupled and ongoing terrestrial ecosystem disturbance and the need for periodic reassessment and maintenance. Traditional biological sampling (e.g., macroinvertebrate sampling or other biological indices) alone seldom identifies the c...
متن کاملComparison between Model-Predicted and Field-Measured Stream Habitat Features for Evaluating Fish Assemblage–Habitat Relationships
—The use of model-predicted, local-scale habitat data as inputs in analyses intended to evaluate multiscale fish assemblage–habitat relationships in streams has become increasingly common as the scale at which such studies are conducted has increased. We used fish assemblage and habitat data from 208 wadeable streams in Wisconsin and Michigan to determine whether model-predicted habitat data wo...
