Cold water as a climate shield to preserve native trout through the 21st Century

Publications Posted on: March 18, 2015
Native trout are culturally and ecologically important, but also likely to undergo widespread declines as the coldwater environments they require continue to shrink in association with global warming.

Role of climate and invasive species in structuring trout distributions in the interior Columbia River Basin, USA

Publications Posted on: August 31, 2011
Recent and projected climate warming trends have prompted interest in impacts on coldwater fishes. We examined the role of climate (temperature and flow regime) relative to geomorphology and land use in determining the observed distributions of three trout species in the interior Columbia River Basin, USA.

Influence of fire on native and nonnative salmonid populations and habitat in a western Montana basin

Publications Posted on: March 30, 2011
Anticipated increases in the frequency and severity of wildfire may threaten the persistence of native salmonid populations in headwater streams in western North America.

Competition and predation as mechanisms for displacement of greenback cutthroat trout by brook trout

Publications Posted on: December 17, 2008
Cutthroat trout Oncorhynchus clarkii frequently are displaced by nonnative brook trout Salvelinus fontinalis, but the ecological mechanisms of displacement are not understood. Competition for food and predation between greenback cutthroat trout O. c. stomias and brook trout were investigated in montane streams of Colorado.

Predicting cutthroat trout (Oncorhynchus clarkii) abundance in high-elevation streams: revisiting a model of translocation success

Publications Posted on: April 10, 2006
Assessing viability of stream populations of cutthroat trout (Oncorhynchus clarkii) and identifying streams suitable for establishing populations are priorities in the western United States, and a model was recently developed to predict translocation success (as defined by an index of population size) of two subspecies based on mean July water temperature, pool bankfull width, and deep pools counts.
