Vertical heterogeneity in the physical characteristics of lakes and oceans is ecologically
salient and exploited by a wide range of taxa through diel vertical migration to enhance their …

Abstract Dams in the Columbia River basin present significant obstacles to declining
populations of anadromous Pacific lampreys Lampetra tridentata. Mitigation efforts have …

We monitored 94 mottled sculpins (Cottus bairdii) marked with passive integrated
transponder (PIT) tags to examine seasonal movement patterns. High detection efficiency …

Habitat heterogeneity can generate intraspecific diversity through local adaptation of
populations. While it is becoming increasingly clear that population diversity can increase …

Generalist predators can contribute to extinction risk of imperiled prey populations even
through incidental predation. Quantifying predation on small populations is important to …

Expression of phenotypic plasticity depends on reaction norms adapted to historic selective
regimes; anthropogenic changes in these selection regimes necessitate contemporary …

We examined the role of individual size and origin (wild versus hatchery) to predation risk
and marine survival for threatened juvenile steelhead (Oncorhynchus mykiss) in a coastal …

We investigated emigration behavior, habitat use, and Na+, K+-ATPase activity levels of
juvenile steelhead trout (sea-run rainbow trout; Oncorhynchus mykiss) in Scott Creek, a …

We investigated the interaction among genetically identified origin, behavioral tendency to
emigrate, and Na+, K+-ATPase enzyme activity in recently diverged subpopulations of …

We compared detection efficiency for three lengths (12, 23 and 32 mm) of half-duplex (HDX)
passive integrated transponder (PIT) tags for both manual tracking and fixed array …
