Some aspects of the comparative ecology of fishes associated with juvenile sockeye salmon, Oncorhynchus nerka (Walbaum), in the lakes of the Naknek river system, Alaska

Creator:: Wallace, Richard L.
Abstract:: A study of the distribution, relative abundance and diet of fishes sympatric with juvenile sockeye salmon, Oncorhynchus nerka (Walbaum), within the freshwater nursery areas of the Naknek River system was undertaken from 1961 to 1963. The study was part of an extensive investigation to determine what factors in the freshwater...

A genetic study of the red-band trout (Salmo sp.)

Creator:: Wilmot, Richard L.
Abstract:: A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

Diversity and distribution of anostomoid fishes (Teleostei: Characiformes) throughout the Guianas

Creator:: Sidlauskas, Brian L. and Vari, Richard P.
Abstract:: Diversité et distribution des poissons anostomoides (Teleostei, Characiformes) dans les Guyanes. Cinquante-six espèces, soit approximativement 20% des Characiformes de la superfamille des Anostomidea (familles des Anostomidae, Chilodontidae, Curimatidae et Prochilodontidae), fréquentent les eaux douces de la Guyane française, du Guyana et du Suriname bien que ces régions ne recouvrent qu’environ...

New species of Cyphocharax (Ostariophysi: Characiformes: Curimatidae) from Suriname and French Guiana and a discussion of curimatid diversity on the Guiana Shield

Creator:: Vari, Richard P., Sidlauskas, Brian L., and Le Bail, Pierre-Yves
Abstract:: Cyphocharax biocellatus, a species of curimatid characiform apparently endemic to the Marowijne River/Fleuve Maroni system in Suriname and French Guiana, and the Maim River basin in French Guiana is described as new. The new species is diagnosed from congeners based on meristic and morphometric features and details of pigmentation of...

Relationship Between Temperature and Ceratomyxa shasta–Induced Mortality In Klamath River Salmonids

Creator:: Ray, R. Adam, Holt, Richard A., and Bartholomew, Jerri L.
Abstract:: Water temperature influences almost every biological and physiological process of salmon, including disease resistance. In the Klamath River (California), current thermal conditions are considered sub-optimal for juvenile salmon. In addition to borderline temperatures, these fish must contend with the myxozoan parasite Ceratomyxa shasta, a significant cause of juvenile salmonid mortality...

Supplemental data to "Casting a broader net: Using microfluidic metagenomics to capture aquatic biodiversity data from diverse taxonomic targets"

Creator:: Hauck, Laura L., Weitemier, Kevin A., Penaluna, Brooke E., Garcia, Tiffany, and Cronn, Richard
Abstract:: This dataset contains the taxonomic classifications of environmental DNA (eDNA) sequences obtained from Fall Creek, Oregon, via microfluidic multiplex PCR (Fluidigm Access Array) and high-throughput sequencing. It is accompanied by electrofishing counts taken at the same time as the eDNA samples. Metadata and R scripts are provided to analyze the...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
