Greater Sage-Grouse National Research Strategy

Creator:: Hanser, Steven E. and Manier, Daniel J.
Abstract:: The condition of the sagebrush ecosystem has been declining in the Western United States, and greater sage-grouse (Centrocercus urophasianus), a sagebrush-obligate species, has experienced concurrent decreases in distribution and population numbers. This has prompted substantial research and management over the past two decades to improve the understanding of sage-grouse and...

Integration of submersible transect data and high-resolution multibeam sonar imagery for a habitat-based groundfish assessment of Heceta Bank, Oregon

Creator:: Nasby-Lucas, Nicole M., Embley, Bob W., Hixon, Mark A., Merle, Susan G., Tissot, Brian N., and Wright, Dawn J.
Abstract:: In the face of dramatic declines in groundfish populations and a lack of sufficient stock assessment information, a need has arisen for new methods of assessing groundfish populations. We describe the integration of seafloor transect data gathered by a manned submersible with high-resolution sonar imagery to produce a habitat- based...

Ambient PM₂.₅, O₃, and NO₂ Exposures and Associations with Mortality over 16 Years of Follow-Up in the Canadian Census Health and Environment Cohort (CanCHEC)

Creator:: Crouse, Dan L., Peters, Paul A., Hystad, Perry, Brook, Jeffrey R., van Donkelaar, Aaron, Martin, Randall V., Villeneuve, Paul J., Jerrett, Michael, Goldberg, Mark S., Pope, C. Arden, Brauer, Michael, Brook, Robert D., Menard, Richard, and Burnett, Richard T.
Abstract:: Background: Few studies examining the associations between long-term exposure to ambient air pollution and mortality have considered multiple pollutants when assessing changes in exposure due to residential mobility during follow-up. Objective: We investigated associations between cause-specific mortality and ambient concentrations of fine particulate matter (≤ 2.5 μm; PM₂.₅), ozone (O₃),...

Ontogenetic patterns and temperature-dependent growth rates in early life stages of Pacific cod (Gadus macrocephalus)

Creator:: Hurst, Thomas P., Laurel, Benjamin J., and Ciannelli, Lorenzo
Abstract:: Pacific cod (Gadus macrocephalus)is an important component of fisheries and food webs in the North Pacific Ocean and Bering Sea. However, vital rates of early life stages of this species have yet to be described in detail. We determined the thermal sensitivity of growth rates of embryos, pref lexion and...

A new species of Sebastes (Scorpaeniformes: Sebastidae) from the northeastern Pacific, with a redescription of the blue rockfish, S. mystinus (Jordan and Gilbert, 1881)

Creator:: Frable, Benjamin W., Wagman, D. Wolfe, Frierson, Taylor N., Aguilar, Andres, and Sidlauskas, Brian L.
Abstract:: The diverse predatory rockfishes (Sebastes spp.) support extensive commercial fisheries in the northeastern Pacific. Although 106 species of Sebastes are considered valid, many of the ecological, geographical, and morphological boundaries separating them lack clarity. We clarify one such boundary by separating the blue rockfish Sebastes mystinus (Jordan and Gilbert, 1881)...

Seasonal and interannual variation in juvenile salmonids and associated fish assemblage in open waters of the lower Columbia River estuary

Creator:: Weitkamp, Laurie A., Bentley, Paul J., and Litz, Marisa N. C.
Abstract:: The transition between freshwater and marine environments is associated with high mortality for juvenile anadromous salmonids, yet little is known about this critical period in many large rivers. To address this deficiency, we investigated the estuarine ecology of juvenile salmonids and their associated fish assemblage in open-water habitats of the...

PCSFN Science Board Report on Youth Sports

Creator:: Cardinal, Bradley J.
Abstract:: A healthy nation starts with healthy citizens, and participation in sports is one of the most powerful ways to promote healthy habits for a lifetime—not only for physical fitness but also for emotional wellbeing and social cohesion. The natural enthusiasm that children and adolescents (collectively referred to as “youth”) have...

Low Concentrations of Bisphenol A Induce Mouse Spermatogonial Cell Proliferation by G Protein–Coupled Receptor 30 and Estrogen Receptor-α

Creator:: Sheng, Zhi-Guo and Zhu, Ben-Zhan
Abstract:: BACKGROUND: Bisphenol A (BPA) is one of the most prevalent chemicals in daily-use materials; therefore, human exposure to BPA is ubiquitous. The estrogenicity of BPA is generally mediated by nuclear estrogen receptors (ERs). However, low concentrations of BPA stimulate seminoma cell proliferation by an uncertain mechanism that does not involve...

Albacore oceanography off Oregon : 1970

Creator:: Pearcy, William G.
Abstract:: During July 1970, albacore boats trolling surface jigs (jig boats) had record catches in an area off the mouth of the Columbia River. The jig fishery declined suddenly in late July and was poor throughout the remainder of the summer. No obvious oceanographic changes were correlated with these drastic changes...

In cold blood: evidence of Pacific sleeper shark (Somniosus pacificus) predation on Steller sea lions (Eumetopias jubatus) in the Gulf of Alaska

Creator:: Horning, Markus and Mellish, Jo-Ann E.
Abstract:: Temperature data received post mortem in 2008–13 from 15 of 36 juvenile Steller sea lions (Eumetopias jubatus) that had been surgically implanted in 2005–11 with dual life history transmitters (LHX tags) indicated that all 15 animals died by predation. In 3 of those 15 cases, at least 1 of the...
