How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

Temporal Variation in the Prey Resource Portfolio of Juvenile Salmonids During Freshwater Rearing

Creator:: Brady, Megan E.
Abstract:: Freshwater rearing is a critical period in the life cycle of anadromous salmonids, known to produce carry-over effects mediating long-term growth and survival. Freshwater growth is primarily determined by food availability and temperature. While many species of salmon rear in freshwater for a full year or longer, most trophic ecology...

Evaluating Fish Rescue as a Drought Adaptation Strategy for Imperiled Coho Salmon: A Life-Cycle Modeling Approach

Creator:: Beebe, Brittany A.
Abstract:: Projected intensification of drought as a result of climate change may reduce the capacity of streams to rear fish, exacerbating the challenge of recovering ESA-listed salmon populations. Without management intervention, some stocks will likely go extinct as stream drying and fragmentation reduce juvenile survival to unsustainable levels. To offset drought-related...

Spatial and Temporal Dynamics of Eulachon (Thaleichthys pacificus) in Northern Southeast Alaska

Creator:: Pochardt, Meredith R.
Abstract:: In Southeast Alaska, Eulachon (Thaleichthys pacificus) are a culturally and biologically important anadromous fish. Eulachon populations have significantly declined in the southern part of their range, and in 2010 eulachon in northern California, Oregon, and Washington were listed as a threatened species under the Endangered Species Act. In the same...

The physiological response of larval Pacific lamprey to chronic heat stress

Creator:: Carilli, Patrick B.
Abstract:: Pacific lamprey is an important cultural and ecological species to freshwater ecosystems of the Pacific Northwest. Lamprey often rear in low gradient portions of watersheds that have high exposure to climate warming, yet very little is known about their thermal physiology in comparison with other anadromous fishes such as Pacific...

Evidence for Cross-Seasonal Effects: Insights from Long-term Data on Northern Pintail

Creator:: Zarzycki, Megan C.
Abstract:: Cross-seasonal effects, where conditions in one season can have consequences in a following season, can have population-level implications for migratory species. To assess the presence of cross-seasonal effects on a migratory dabbling duck population, we examined the relative importance of habitat conditions in multiple seasons on the subsequent productivity of...

Mercury accumulation in fish from Cottage Grove Reservoir and its tributaries

Creator:: Worcester, Thomas C
Abstract:: A fish sampling program was initiated at Cottage Grove Reservoir in June of 1974 to investigate mercury accumulation in the fish. Samples were collected periodicallv from June to November, 1974, and from June, 1975 through January, 1976 from both the reservoir and its tributaries. Species collected included spring chinook salmon...

Migratory behavior and passage of redband trout (Oncorhynchus mykiss) in the Donner und Blitzen River, Oregon

Creator:: Anderson, Matthew C.
Abstract:: Salmonids in arid high-elevation streams find themselves at the fringe of their tolerance range. Under the conditions they endure in such environments, long-distance migratory movements among widely dispersed habitats may be an important mechanism for some fish to persist, and even thrive. The Donner und Blitzen (Blitzen) River redband trout...

Population demography, resource use, and movement in cooperatively breeding Micronesian Kingfishers

Creator:: Kesler, Dylan C.
Abstract:: Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...
