The effects of electroshock on immune function and disease progression in juvenile spring chinook salmon

Creator:: VanderKooi, Scott P., Maule, Alec G., and Schreck, Carl B.
Abstract:: Although much is known about the effects of electroshock on fish physiology, consequences to the immune system and disease progression have not received attention. Our objectives were to determine the effects of electroshock on selected immune function in juvenile spring chinook salmon Oncorhynchus tshawytscha, the mechanism of any observed alteration,...

Effects of Ground Failure on Bridges, Roads, and Railroads

Creator:: Ledezma, Christian, Hutchinson, Tara, Ashford, Scott A., Moss, Robb, Arduino, Pedro, Bray, Jonathan D., Olson, Scott, Hashash, Youssef M. A., Verdugo, Ramon, Frost, David, Kayen, Robert, and Rollins, Kyle
Abstract:: The long duration and strong velocity content of the motions produced by the 27 February 2010 Maule earthquake resulted in widespread liquefaction and lateral spreading in several urban and other regions of Chile. In particular, critical lifeline structures such as bridges, roadway embankments, and railroads were damaged by ground shaking...

An evaluation of orange and clear traps with pear ester to monitor codling moth (Lepidoptera: Tortricidae) in apple orchards, Evaluación de trampas naranjas y transparentes con éster de pera para monitorear la polilla de la manzana (Lepidoptera: Tortricidae) en huertos de manzano

Creator:: Barros-Parada, Wilson, Knight, Alan L., Basoalto, Esteban, and Fuentes-Contreras, Eduardo
Abstract:: Studies were conducted to evaluate the use of several trap-lure combinations to improve the monitoring of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), in apple, Malus domestica Bordk. The treatments involved the use of clear, orange, and white traps baited with one or more of the following attractants: the major...

Is long primary growth associated with stem sinuosity in Douglas-fir?

Creator:: Gartner, Barbara L. and Johnson, G. R.
Abstract:: Stem sinuosity is a highly visible stem-form trait in the leaders of fast-growing Douglas-fir (Pseudotsuga menziesii var. (Mirb.) Franco) trees, yet its cause is unknown. We tested the hypotheses that sinuous stems have longer expanses of primary growth than nonsinuous stems (putting the leader at higher risk curvature, induction of...

Changes in Avoidance Response Time of Juvenile Chinook Salmon Exposed to Multiple Acute Handling Stresses

Creator:: Sigismondi, Linda A. and Weber, Lavern J.
Abstract:: A simple behavioral test was devised to determine the effects of multiple acute stresses on the avoidance response time of fish. Groups of freshwater-adapted juvenile chinook salmon Oncorhynchus tshawytscha were exposed to a sudden overhead light and the time it took each fish to reach cover was noted. Tests were...

An Evaluation of the Influence of Stock Origin and Outmigration History on the Disease Susceptibility and Survival of Juvenile Chinook Salmon

Creator:: Dietrich, Joseph P., Boylen, Deborah A., Thompson, Donald E., Loboschefsky, Erik J., Bravo, Claudia F., Spangenberg, Dina K., Ylitalo, Gina M., Collier, Tracy K., Fryer, Derek S., Arkoosh, Mary R., and Loge, Frank J.
Abstract:: Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may...

Beyond dichotomous life histories in partially migrating populations: cessation of anadromy in a long-lived fish

Creator:: Bond, Morgan H. and Miller, Jessica A.
Abstract:: Across animal taxa, migration allows individuals to exploit habitats and resources that predictably vary seasonally in suitability. Theory predicts that the ‘‘decision’’ to migrate or not is shaped by the relative fitness costs and benefits of exhibiting a given life history. Adoption of a migratory strategy is widely thought to...

Susceptibility of Juvenile Steelhead to Avian Predation: the Influence of Individual Fish Characteristics and River Conditions

Creator:: Hostetter, Nathan J., Evans, Allen F., Roby, Daniel D., and Collis, Ken
Abstract:: Identification of the factors that influence susceptibility to predation can aid in developing management strategies to recover fish populations of conservation concern. Predator-prey relationships can be influenced by numerous factors, including prey condition, prey size, and environmental conditions. We investigated these factors by using juvenile steelhead Oncorhynchus mykiss from the...

Influence of climate and land use in carbon biogeochemistry in lower reaches of rivers in central southern Chile: Implications for the carbonate system in river-influenced rocky shore environments

Creator:: Pérez, Claudia A., DeGrandpre, Michael D., Lagos, Nelson A., Saldías, Gonzalo S., Cascales, Emma-Karin, and Vargas, Cristian A.
Abstract:: Freshwater discharge affects the biogeochemistry of river-influenced nearshore environments by contributing with carbon and nutrients. An increase in human activities in river basins may alter the natural riverine nutrients and carbon export to coastal ecosystems. Along a wide latitudinal range (32° 55'S-40° 10'S), this study explores the role of climate...

The Politics of Correctional Privatization in the United States

Creator:: Burkhardt, Brett C.
Abstract:: Research Summary: Private correctional firms are political actors. They work to create favorable conditions to market their services. At the same time, they are constrained by external political forces, including political parties, social movements, and public opinion. This article reviews what we know about the reciprocal relationship between the private...
