TL;DR: Despite some uncertainty, large declines in trout habitat are likely, but the findings point to opportunities for strategic targeting of mitigation efforts to appropriate stressors and locations.

TL;DR: This paper used downscaled outputs from general circulation models coupled with a hydrologic model to forecast the effects of altered flows and increased temperatures on four interacting species of trout across the interior western United States (1.01 million km2), based on empirical statistical models built from fish surveys at 9,890 sites.
Journal ArticleDOI
Metapopulation structure of bull trout: influences of physical, biotic, and geometrical landscape characteristics
Jason B. Dunham,Bruce E. Rieman +1 more
TL;DR: Bull trout populations in smaller, isolated, and more disturbed habitats may be at risk of extinction, and metapopulation structure implies the existence of suitable, but presently unoccupied habitat, which should be managed carefully to facilitate potential natural recolonization or reintroductions of bull trout.
Journal ArticleDOI
Metapopulations and salmonids: a synthesis of life history patterns and empirical observations
Bruce E. Rieman,Jason B. Dunham +1 more
TL;DR: It is suggested that simple generalizations of salmonid metapopulation are inappropriate and the relevance of extinction and colonization pro- cesses are likely to vary with life history, species, scale, and landscape.
Journal ArticleDOI
Invasion versus isolation: trade-offs in managing native salmonids with barriers to upstream movement.
TL;DR: A conceptual model of the joint trade-off of invasion and isolation threats that considers the opportunities for managers to make strategic decisions is developed and illustrated use of this framework in an analysis of the invasion-isolation trade-offs for native cutthroat trout in 2 contrasting basins in western North America.
