Macroscale hydrologic modeling of ecologically relevant flow metrics in small streams, credited to Hamlet, A F, published in 2010. Published in USFS Region 6 annual meeting, Vancouver, WA., in 2010.
Mountain streams provide important habitats for many species, but their faunas are especially vulnerable to climate change because of ectothermic physiologies and movements that are constrained to linear networks that are easily fragmented. Effectively conserving biodiversity in these systems requires accurate downscaling of climatic trends to local habitat conditions, but downscaling is difficult in complex terrains given diverse microclimates and mediation of stream heat budgets by local conditions. We compiled a stream temperature database (n = 780) for a 2500-km river network in central Idaho to assess possible trends in summer temperatures and thermal habitat for two native salmonid species from 1993 to 2006....

Abstract Unpaved forest roads remain a pervasive disturbance on public lands and mitigating sediment from road networks remains a priority for management agencies. Restoring roaded landscapes is becoming increasingly important for many native coldwater fishes that disproportionately rely on public lands for persistence. However, effectively targeting restoration opportunities requires a comprehensive understanding of the effects of roads across different ecosystems. Here, we combine a review and a field study to evaluate the status of knowledge supporting the conceptual framework linking unpaved forest roads with streambed sediment. Through our review, we specifically focused on those studies linking measures of...
Stream thermal regimes and aquatic ecosystems in a changing climate, credited to Luce, Charles H., published in 2009. Published in Western Watersheds and Climate Change Workshop. Boulder, CO. November 17 – 19., in 2009.
Temperature, flow regime and biotic interactions determine differential responses of four trout species to projected climate change (In preparation), credited to Dauwalter, M.M., published in 2011.
Past and Future Effects of Climate Change on Stream Thermal Regimes, credited to Luce, Charles H., published in 2010. Published in USFS Region 1 and 6 annual meetings. Vancouver, Washington and Missoula, MT., in 2010.
Most climate change research has focused on threats to native species, but non-native, invasive species may be impacted as well. We show that warmer temperatures and shifts from snowmelt runoff regimes to mixed runoff regimes in parts of the Northern Rocky Mountains, US, may reduce the occurrence of nonnative brook trout (Salvelinus fontinalis) and indirectly benefit the native cutthroat trout (Oncorhynchus clarkii). Differences in reproductive strategy may account for the differential responses of the two species. We base these findings on models of species occurrence that use landscape and climatic variables as predictors and are built from a database of >4000 fish collection points. We estimate changes in stream...
Our objective in this study was to conduct additional validations of the VIC model outputs for the region around the Shoshone National Forest by comparing modeled predictions to observed USGS gage data at selected locations. In addition, we compared model performance to that of hydrologic outputs from MC1 (Daly et al. 2000, Bachelet et al. 2001), a dynamic model that simulates vegetation, carbon, hydrology and fire processes.

Adapting the VIC hydrologic model to headwater streams in the West, credited to Hamlet, A F, published in 2009. Published in US Forest Service Western Watersheds and Climate Change Workshop, Boulder, CO. November 18, 2009, in 2009.
Effects of Climate Change on Stream Temperatures and Hydrologies: Ongoing Patterns and Emerging Tools for Predicting Change, credited to Luce, Charles H., published in 2010. Published in USFS Region 4 annual meeting. Ogden, UT., in 2010.
Flow regime influences distributions of brook trout, bull trout and cutthroat trout in the Upper Columbia Basin, credited to Hamlet, A F, published in 2010. Published in Idaho Chapter of the American Fisheries Society Annual Meeting, Pocatello, ID. March 5, 2010, in 2010.
Effects of climate change on native and introduced trout in the Columbia River Basin, credited to Nagel, David E., published in 2010. Published in Interior Columbia Basin Interagency Deputy Team Meeting. Spokane, WA. December 7, 2010, in 2010.
