Remaining populations of an upland stream fish persist in refugia defined by habitat features at multiple scales Remaining populations of an upland stream fish persist in refugia defined by habitat features at multiple scales
Aim Conserving stream biota could require strategies that preserve habitats conveying resistance to ecological impacts of changing land use and climate. Retrospective analyses of species’ responses to anthropogenic disturbances can inform such strategies. We developed a hierarchical framework to contrast environmental conditions underlying persistence versus extirpation of an imperilled...

Size-structured habitat selection by arapaima in floodplain lakes of the lower Amazon Size-structured habitat selection by arapaima in floodplain lakes of the lower Amazon
Human modification of floodplain ecosystems is widespread and a major threat to fish populations, particularly in the tropics where fish diversity and rates of floodplain degradation are high. Identifying measures to minimize the susceptibility of floodplain fishes to habitat modification requires understanding dry-season lake habitat selection for species of conservation concern.This...

A new modeling approach to prioritize riparian restoration to reduce sediment loading in two Virginia river basins A new modeling approach to prioritize riparian restoration to reduce sediment loading in two Virginia river basins
Human impact, particularly land cover changes (e.g., agriculture, construction) increase erosion and sediment loading into streams. Benthic species are negatively affected by silt deposition that coats and embeds stream substrate. Given that riparian buffers are effective sediment filters, riparian restoration is increasingly implemented by conservation groups to protect stream habitats...

Macroinvertebrate sensitivity thresholds for sediment in Virginia streams Macroinvertebrate sensitivity thresholds for sediment in Virginia streams
Sediment is the most commonly identified pollutant associated with macroinvertebrate community impairments in freshwater streams nationwide. Management of this physical stressor is complicated by the multiple measures of sediment available (e.g., suspended, dissolved, bedded) and the variability in natural “healthy” sediment loadings across ecoregions. Here we examine the relative...

Spatial extent of analysis influences observed patterns of population genetic structure in a widespread darter species (Percidae) Spatial extent of analysis influences observed patterns of population genetic structure in a widespread darter species (Percidae)
Connectivity among stream fish populations allows for exchange of genetic material and helps maintain genetic diversity, adaptive potential and population stability over time. Changes in species demographics and population connectivity have the potential to permanently alter the genetic patterns of stream fish, although these changes through space and time are variable and understudied...

Rivers are social–ecological systems: Time to integrate human dimensions into riverscape ecology and management Rivers are social–ecological systems: Time to integrate human dimensions into riverscape ecology and management
Incorporation of concepts from landscape ecology into understanding and managing riverine ecosystems has become widely known as riverscape ecology. Riverscape ecology emphasizes interactions among processes at different scales and their consequences for valued ecosystem components, such as riverine fishes. Past studies have focused strongly on understanding the ecological processes in...
