The influences of sex and posture on joint energetics during drop landings

Creator:: Norcross, Marc F., Shultz, Sandra J., Weinhold, Paul S., Lewek, Michael D., Padua, Darin A., and Blackburn, J. Troy
Abstract:: Previous observations suggest that females utilize a more erect initial landing posture than males with sex differences in landing posture possibly related to sex-specific energy absorption (EA) strategies. However, sex-specific EA strategies have only been observed when accompanied by sex differences in initial landing posture. This study: 1) investigated the...

Ammonia control best management practices

Creator:: Downing, Troy (Troy Woerner) and Gamroth, Michael J.
Abstract:: "There is growing interest in odor and gaseous emissions from livestock operations because of concern about global warming and enforcement of the Clean Air Act. This bulletin provides and evaluates best management practices for the control of ammonia lost to the air on dairy farms. Benefits are based on an...

Marine bird aggregations associated with the tidally-driven plume and plume fronts of the Columbia River

Creator:: Zamon, Jeannette E., Phillips, Elizabeth M., and Guy, Troy J.
Abstract:: Freshwater discharge from large rivers into the coastal ocean creates tidally-driven frontal systems known to enhance mixing, primary production, and secondary production. Many authors suggest that tidal plume fronts increase energy flow to fish-eating predators by attracting planktivorous fishes to feed on plankton aggregated by the fronts. However, few studies...

Effects of the 1997-1998 El Niño on early-juvenile Pacific hake Merluccius productus: age, growth, abundance, and diet in coastal nursery habitats

Creator:: Grover, Jill J., Buckley, Troy W., and Woodbury, David
Abstract:: The effects of anomalous oceanographic conditions on growth, abundance, spawn-date distributions, and diet of early-juvenile Pacific hake Merluccius productus were examined in nursery grounds off the coast of central California, USA. Spring collections from 2 consecutive years of El Nino conditions, 1997 and 1998, 1 year of La Nina conditions,...

Evaluation of a Selective Flatfish Trawl and Diel Variation in Rockfish Catchability as Bycatch Reduction Tools in the Deepwater Complex Fishery off the U.S. West Coast

Creator:: Hannah, Robert W., Parker, Steven J., and Buell, Troy V.
Abstract:: We tested the potential of a selective flatfish trawl to reduce bycatch of slope rockfish in the upper continental slope bottom-trawl fishery (250–500 m) on the U.S. West Coast. The trawl we tested differed from typical slope trawls in that it was a low-rise, two-seam trawl with a severely cut...

Valuing forages based on moisture and nutrient content

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, United States. Department of Agriculture, Pacific Northwest Cooperative Extension, Downing, Troy (Troy Woerner), Gamroth, Michael J., and Schneider, Gary L.
Abstract:: High-quality forages, such as alfalfa and grasses, are important for efficient milk production from dairy cows. Forages provide the effective fiber that is critical for good health and longevity. Inadequate effective fiber in the cow’s diet is one reason for acidosis and milk fat depression. Historically, when forage quality changed,...

Abstract:: Winter climate is expected to change under future climate scenarios, yet the majority of winter ecology research is focused in cold-climate ecosystems. In many temperate systems, it is unclear how winter climate relates to biotic responses during the growing season. The objective of this study was to examine how winter...

Assessing and addressing the re-eutrophication of Lake Erie: Central basin hypoxia

Creator:: Scavia, Donald, Allan, J. David, Arend, Kristin K., Brandt, Stephen B., Bartell, Steven, Bosch, Nate S., Briland, Ruth D., Daloğlu, Irem, DePinto, Joseph V., Dolan, David M., Evans, Mary Anne, Farmer, Troy M., Goto, Daisuke, Han, Haejin, Höök, Tomas O., Knight, Roger, Ludsin, Stuart A., Mason, Doran, Michalak, Anna M., Richards, R. Peter, Roberts, James J., Rucinski, Daniel K., Rutherford, Edward, Schwab, David J., Sesterhenn, Timothy M., Zhang, Hongyan, and Zhou, Yuntao
Abstract:: Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased phosphorus inputs degraded water quality and reduced central basin hypolimnetic oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms and contributed to the extirpation of important benthic macroinvertebrate...
