Carnivore Competition: Spatial and Dietary Implications of Gray Wolf Recolonization for Cougars in Northeast Oregon

Creator:: Orning, Elizabeth Kari
Abstract:: After a 40-year absence from Oregon’s landscape, expanding gray wolf (Canis lupus) populations are reestablishing elements of interspecific competition with sympatric large carnivores, like cougars (Puma concolor). This presents new challenges for management of large carnivores and their ungulate prey populations (e.g., elk, Cervus canadensis nelsoni; mule deer, Odocoileus hemionus)...

Definitive hosts of the trematode vector, Nanophyetus salmincola

Creator:: Schlegel, Michael Wesley
Abstract:: Of 149 wild animals from two western Oregon river drainage areas and other localities in which "salmon poisoning" disease (SPD) is enzootic, including ten mammalian and two avian species, 79 harbored Nanophyetus salmincola, the SPD vector. The shorttail weasel, Mustela erminea; river otter, Lutra canadensis; spotted skunk, Spilogale putorius; Norway...

Over-wintering diet, growth, and prey available to juvenile coho salmon (Oncorhynchus kisutch) in the West Fork Smith River, Oregon

Creator:: Olegario, Anthony
Abstract:: Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...

Mercury and molt: no strong Hg trend across songbird primaries

Creator:: Ramsden, Danielle K., Low, Katherine E., Jackson, Allyson K., Emery, Colleen, and Eagles-Smith, Collin A.
Abstract:: Mercury (Hg) is a bioaccumulative metal that can threaten the health of wild birds. Feathers are commonly used biomonitoring tools for non-lethally estimating Hg exposure in birds because they contain stable Hg concentrations upon completion of feather growth, when blood flow to the feather has stopped. Despite the common use...

You are What, When, Where, and How you Eat : Mercury in Avian Food Webs across Multiple Spatial Scales

Creator:: Jackson, Allyson K.
Abstract:: Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

Vertebral elemental markers in elasmobranchs : potential for reconstructing environmental history and population structure

Creator:: Smith, Wade D.
Abstract:: Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...

Bycatch in the ocean shrimp Pandalus jordani fishery

Creator:: Hoover Krutzikowsky, Vicki
Abstract:: The purpose of this research was to explore the impact of finfish bycatch on the ocean shrimp Pandalus jordani fishery using two methods. One method looked at the breakage of the shrimp by finfish bycatch in the nets. The other looked at the impact of bycatch on fishing decisions. At-sea...

Native Bee and Spider Community Responses to Grassland Restoration and Wildfire

Creator:: Smith DiCarlo, Lauren A.
Abstract:: Up to 99.9% of native North American grasslands have been degraded since European settlement, primarily due to agricultural conversion. Today, grasslands are a top priority for restoration as they provide essential habitat for many rare and endangered species; however, the majority of studies in grasslands have focused on vegetation or...
