Spawning habitat suitability for coastal cutthroat trout: Microhabitat and mesohabitat

Autor: Steven N. Boessow, Kiza K. Gates, Hal A. Beecher

Publikováno v: Aquatic Conservation: Marine and Freshwater Ecosystems. 31:480-493

The conservation of aquatic species with complex life histories requires the protection of habitat for each life stage. Coastal cutthroat trout (Oncorhynchus clarkii clarkii) exhibit both mobile and sessile stages and are of conservation concern in n

Why advocate—and how?

Autor: J. Hal Michael, Jim Burroughs, Dominick A. DellaSala, Arthur C. Knutson, Robert M. Hughes, Beverly E. Law, Hal A. Beecher, Robert L. Vadas

Humans are responsible for accelerated global overheating because of positive feedback loops between the climate and land use. It is past time for the scientific community to provide clear information on ways to address such challenges using sound sc

Developing Bioenergetic-Based Habitat Suitability Curves for Instream Flow Models

Autor: Ron Ptolemy, Hal A. Beecher, Jordan S. Rosenfeld

Publikováno v: North American Journal of Fisheries Management. 36:1205-1219

Instream flow models link a physical habitat model that predicts flow-related changes in hydraulics to a biological model that predicts the response of fish to altered velocity and depth. Habitat suitability curves (HSCs) based on frequency of habita

Coastal Cutthroat Trout Redd Counts Impacted by Natural Water Supply Variations

Autor: Steven N. Boessow, Jonathan H. Kohr, Hal A. Beecher, Robert L. Vadas

Publikováno v: North American Journal of Fisheries Management. 36:900-912

During 2001–2003, we counted redds of Coastal Cutthroat Trout Oncorhynchus clarkii clarkii and measured microhabitat variables at fresh redds in Irely Creek upstream of Irely Lake in a largely undisturbed watershed within Olympic National Park, Was

An Empirical Assessment of PHABSIM Using Long-Term Monitoring of Coho Salmon Smolt Production in Bingham Creek, Washington

Autor: Dave Seiler, S. Brett DeMond, Steven N. Boessow, Brad A. Caldwell, Hal A. Beecher

Publikováno v: North American Journal of Fisheries Management. 30:1529-1543

We conducted a PHABSIM study on Bingham Creek, Washington, by using validated habitat suitability criteria for the rearing of coho salmon Oncorhynchus kisutch. We compared the relationship between weighted usable area (WUA) and flow with a previously

Evaluation of Depth and Velocity Preferences of Juvenile Coho Salmon in Washington Streams

Autor: S. Brett DeMond, Hal A. Beecher, Brad A. Caldwell

Publikováno v: North American Journal of Fisheries Management. 22:785-795

We determined depth and velocity preference curves for juvenile coho salmon Oncorhynchus kisutch for input into the physical habitat simulation system of the instream flow incremental methodology. Preferences were determined by scaling the maximum va

Notes: Utility of Depth and Velocity Preferences for Predicting Steelhead Parr Distribution at Different Flows

Autor: John P. Carleton, Thom H. Johnson, Hal A. Beecher

Publikováno v: Transactions of the American Fisheries Society. 124:935-938

We tested an assumption of the instream flow incremental methodology that depth and velocity preferences are independent of streamflows. We had previously developed depth and velocity preferences (P[d] and P[v]) for juvenile (parr) steelhead Oncorhyn
