Effects of population increase on cui-ui growth and maturation Effects of population increase on cui-ui growth and maturation
Cui-ui Chasmistes cujus is endemic to Pyramid Lake, Nevada. The cui-ui population declined during much of the 20th century as a result of water diversion and the formation of a shallow and virtually impassable delta at the mouth of the Truckee River, its spawning habitat. The population increased more than 10-fold to more than 1 million adults after access to the river was restored...

Effects of antenna length and material on output power and detection of miniature radio transmitters Effects of antenna length and material on output power and detection of miniature radio transmitters
The optimal antenna of transmitters used in small aquatic animals is often a compromise between efficient radio wave propagation and effects on animal behavior. Radio transmission efficiency generally increases with diameter and length of the conductor, but increased antenna length or weight can adversely affect animal behavior. We evaluated the effects of changing antenna length and...

Chemical contaminants in fish feeds used in federal salmonid hatcheries in the USA Chemical contaminants in fish feeds used in federal salmonid hatcheries in the USA
Recent studies have demonstrated that fish feeds contain significant concentrations of contaminants, many of which can bioaccumulate and bioconcentrate in fish. Organochlorine (OC) contaminants are present in the fish oils and fish meals used in feed manufacture, and some researchers speculate that all fish feeds contain measurable levels of some contaminants. To determine the...

Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene
Glycoprotein (G) gene nucleotide sequences of four Korean isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed to evaluate their genetic relatedness to worldwide isolates. All Korean isolates were closely related to Japanese isolates of genogroup JRt rather than to those of North American and European genogroups. It is believed that Korean IHNV has been most likely...

Evolutionary history of the ABCB2 genomic region in teleosts Evolutionary history of the ABCB2 genomic region in teleosts
Gene duplication, silencing and translocation have all been implicated in shaping the unique genomic architecture of the teleost MH regions. Previously, we demonstrated that trout possess five unlinked regions encoding MH genes. One of these regions harbors ABCB2 which in all other vertebrate classes is found in the MHC class II region. In this study, we sequenced a BAC contig for the...

Developing methods to assess and predict the population level effects of environmental contaminants. Developing methods to assess and predict the population level effects of environmental contaminants.
The field of ecological toxicity seems largely to have drifted away from what its title implies--assessing and predicting the ecological consequences of environmental contaminants--moving instead toward an emphasis on individual effects and physiologic case studies. This paper elucidates how a relatively new ecological methodology, interaction assessment (INTASS), could be useful in...

Coastal habitats in Puget Sound: A research plan in support of the Puget Sound Nearshore Partnership Coastal habitats in Puget Sound: A research plan in support of the Puget Sound Nearshore Partnership
The purpose of this research plan is to identify high-priority research goals and objectives and delineate the critical questions and information gaps that need to be addressed to provide natural-resource managers and policy- and decisionmakers with tools to effectively undertake restoration planning and adaptive management of the nearshore ecosystems of Puget Sound.
