In the Pacific Northwest, widespread stream channel simplification has led to a loss of
habitat area and diversity for rearing salmon. Subsequent efforts throughout the Columbia …

Climate change is reducing summertime water availability and elevating water temperature,
placing human consumptive needs in competition with needs of coldwater fishes. We …

Stream temperature dynamics during winter are less well studied than summer thermal
regimes, but the winter season thermal regime can be critical for fish growth and …

Mountain watersheds often contain a mosaic of glacier‐, snow‐, and rain‐fed streams that
have distinct hydrologic, temperature, and biogeochemical regimes. However, as glaciers …

Riprap, consisting of large boulders or concrete blocks, is extensively used to stabilize
streambanks and to inhibit lateral erosion of rivers, yet its effect on river morphology and its …

Barrier effects observed in the presence of weirs are exacerbated by low water levels. We
conducted a 10-year study to assess the ecological effects of stream restoration while …

Habitat fragmentation is a pervasive threat to biodiversity. Linearly arranged habitats such
as stream networks are particularly vulnerable to fragmentation. As the landscape becomes …

Recent improvements in tagging technology allow for the examination of the migration of
individual fish, the detection of previously unidentified life histories, and the detailed …

Abstract Changes in biophysical conditions through time generate spatial and temporal
variability in habitat quality across landscapes. For river ecosystems, researchers are …

Wildfire has become increasingly common and severe across forested landscapes. Shortly
after wildfire, loss of riparian cover along streams and subsequent increases in light can …
