Identification and systematics of larvae of Artedius, Clinocottus, and Oligocottus (Scorpaeniformes:Cottidae)

Creator:: Washington, Betsy B.
Abstract:: Complete, identified, developmental series of larval cottids Artedius fenestralis, A. creaseri, A. meanyi, Oligocottus snyderi, Clinocottus embryum, and C. globiceps are described for the first time. In addition, redescriptions of four species, Artedius harringtoni, A. lateralis, Oligocottus maculosus, and Clinocottus acuticeps are included that provide new and comparative information on...

Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics

Creator:: Johansson, Mattias L., Litz, Marisa N. C., Brodeur, Richard D., Britt, Tristan A., Vanegas, Camilo A., Hyde, John R., and Banks, Michael A.
Abstract:: Cytochrome B sequence data (FASTA format) from the paper “Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics”. The data was generated from a sample of 2534 unknown, field collected late-larval and juvenile rockfishes from the Pacific...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

Elevational differences in UV-B response by the long-toed salamander (Ambystoma macrodactylum)

Creator:: Thurman, Lindsey L.
Abstract:: Global amphibian declines have been attributed to numerous and often synergistic causes, such as invasive species, pathogens, and ultraviolet-B (UV-B) radiation. The effects of these stressors are context dependent and can vary with location, species, and populations. As sensitivity to UV-B has shown inconsistencies across amphibian taxa, it can be...

Phenotypic comparison of hatchery and wild coho salmon (Oncorhynchus kisutch) in Oregon, Washington, and California

Creator:: Hjort, Randy Carl
Abstract:: Phenotypic similarities of coho salmon (Oncorhynchus kisutch) stocks from Oregon, Washington, and California were compared using agglomerative and divisive cluster analyses. The phenotypic characters evaluated included the following: 1) the isozyme gene frequencies of transferrin and phosphoglucose isomerase; 2) the life history characters time of peak spawning and proportion of...

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...

Life history patterns of two allopatric clupeids : Atlantic menhaden (Brevoortia tyrannus) and gulf menhaden (B. patronus)

Creator:: Powell, Allyn B.
Abstract:: Atlantic menhaden, compared to gulf menhaden, exhibit a life history pattern that appears to be adapted to a more unpredictable reproductive environment. From experiments on laboratory-reared eggs and larvae, Atlantic menhaden have larger eggs with larger yolk volume. They are larger at hatching, utilize their yolk faster, begin feeding at...

Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:: Loschl, Peter J.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

Interactions between stocked trout and larval salamanders (Ambystoma macrodactylum) in high-elevation lakes

Creator:: Tyler, Torrey J.
Abstract:: The long-toed salamander (Ambystoma macrodactylum) is the top vertebrate predator in fishless high-elevation lakes in North Cascades National Park Service Complex (NOCA), Washington. The purpose of this research was to determine the effects of physico-chemical factors and introduced trout on abundance and behavior of A. macrodactylum larvae. Although high-elevation lakes...
