Salinity effects on plasma ion levels, cortisol, and osmolality in Chinook salmon following lethal sampling

Creator:: Stewart, Heather A., Noakes, David L. G., Cogliati, Karen M., Peterson, James T., Iversen, Martin H., and Schreck, Carl B.
Abstract:: Studies on hydromineral balance in fishes frequently employ measurements of electrolytes following euthanasia. We tested the effects of fresh- or salt-water euthanasia baths of tricaine mesylate (MS-222) on plasma magnesium (Mg²⁺) and sodium (Na⁺) ions, cortisol and osmolality in fish exposed to saltwater challenges, and the ion and steroid hormone...

Analysis of salmonid leukocytes purified by hypotonic lysis of erythrocytes

Creator:: Crippen, Tawni L., Bootland, Linda M., Leong, Jo-Ann C., Fitzpatrick, Martin S., Schreck, Carl B., and Vella, Anthony T.
Abstract:: A technique that uses hypotonic lysis of erythrocytes was optimized for the purification of leukocytes from the peripheral blood and anterior kidney (pronephros) of rainbow trout Oncorhynchus mykiss. Comparisons of initial blood dilution (1:2, 1:4, and 1:6) and the time of exposure to hypotonic conditions (10, 20, and 40 s)...

On Nonparametric Estimation: With a Focus on Agriculture

Creator:: Färe, Rolf, Grosskopf, Shawna, Pasurka, Carl, and Martins-Filho, Carlos
Abstract:: We review nonparametric estimation of efficiency and productivity, by which we mainly mean activity analysis, or data envelopment analysis (DEA). The review covers topics that we hope will be of special interest to those doing research in the realm of agriculture. We also include a brief appendix addressing nonparametric estimation...

First Report of Cocksfoot mottle virus Infecting Dactylis glomerata in Oregon and the United States

Creator:: Alderman, S. C., Martin, R. C., Gilmore, B. S., Martin, R. R., Hoffman, G. D., Sullivan, C. S., and Anderson, N. P.
Abstract:: Cocksfoot mottle virus (CfMV) is a mechanically and beetle-transmitted, non-seedtransmitted sobemovirus associated with orchardgrass (Dactylis glomerata L.) stand decline in Europe, Japan, New Zealand (Mahy and Van Regenmortel 2010), and Canada (Bittman et al. 2006). Additional hosts, reported from New Zealand (Delmiglio et al. 2010), include Festuca novae-zelandiae, Lolium spp.,...

Factors influencing density, distribution, and mesohabitat selection of juvenile wild salmonids and residual hatchery winter steelhead

Creator:: Brignon, William R., Olson, Douglas E., Schaller, Howard A., and Schreck, Carl B.
Abstract:: To best manage Eagle Creek National Fish Hatchery, negative interactions between hatchery salmonids and Endangered Species Act listed wild salmonids in the Eagle Creek Basin need to be minimized. Our objectives were: 1) to compare summer rearing densities in two similar streams, where one stream received a release of hatchery...

Potential classification of sex and stage of gonadal maturity of wild white sturgeon using blood plasma indicators

Creator:: Webb, Molly A. H., Feist, Grant W., Foster, Eugene P., Schreck, Carl B., and Fitzpatrick, Martin S.
Abstract:: Twenty-two steelhead trout (Salmo gairdneri) containing coded wire tags (CWT's) were captured in gillnets fished by the Oshoro-Maru in the Gulf of Alaska and along 180 during 1982-85. These fish originated from North American streams and hatcheries in British Columbia, Idaho, and Washington. One fish was age 0.1, 16 were...

Net Returns from Segregating Dark Northern Spring Wheat by Protein Concentration during Harvest

Creator:: Long, Dan S., McCallum, John D., Martin, Charles T., and Capalbo, Susan M.
Abstract:: In-line, optical sensing has been developed for on-combine measurement and mapping of grain protein concentration (GPC). The objective of this study was to estimate changes in costs and net returns from using this technology for segregation of the dark northern spring (DNS) subclass of hard red wheat (Triticum aestivum L.)...

Tectonically controlled origin of three unusual rock suites in the Woodlark basin

Creator:: Abbott, Dallas and Fisk, Martin R.
Abstract:: We propose alternative mechanisms for the origin of three unusual rock suites, high-Mg andesites, NaTi basalts, and arclike rocks, that have been dredged from the Woodlark basin, southwest Pacific Ocean. We show that the high-Mg andesites and NaTi basalts are associated with an unusually cool ridge environment. The cooling is...

A comparison of the behavior and survival of juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (O. mykiss) in a small estuary system

Creator:: Clements, Shaun, Stahl, Thomas, and Schreck, Carl B.
Abstract:: We used radio and acoustic telemetry to study the behavior and survival of wild steelhead trout (Oncorhynchus mykiss) and hatchery coho salmon (Oncorhynchus kisutch) and steelhead outmigrants in a small coastal estuary during two years. Survival was generally low for hatchery fish but more variable, both within and between years,...

Modeling the effects of forest management on in situ and ex situ longleaf pine forest carbon stocks

Creator:: Gonzalez-Benecke, C. A., Samuelson, L. J., Martin, T. A., Cropper, W. P., Jr., Johnsen, K. H., Stokes, T. A., Butnor, J. R., and Anderson, P. H.
Abstract:: Assessment of forest carbon storage dynamics requires a variety of techniques including simulation models. We developed a hybrid model to assess the effects of silvicultural management systems on carbon (C) budgets in longleaf pine (Pinus palustris Mill.) plantations in the southeastern U.S. To simulate in situ C pools, the model...
