Life History of the Northern Rubber Boa (Charina bottae) in Oregon

Creator:: Leppin, Mark V.
Abstract:: The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...

The Effects of Nitrate and a Pathogenic Fungus, Batrachochytrium dendrobatidis, on Amphibians

Creator:: Negru, Delia
Abstract:: The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...

Agricultural impacts on amphibian survival, growth, and distributions

Creator:: Baker, Nick J.
Abstract:: The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss,...

Multi-scale relationships between aspen and birds in the northern Yellowstone ecosystem

Creator:: Hollenbeck, Jeff P., 1967-
Abstract:: I conducted a multi-scale evaluation of aspen – bird relationships in the northern ungulate winter range of the northern Yellowstone ecosystem during June 2001-03. Questions addressed were: (1) Does bird diversity increase with conifer presence in aspen stands? (2) Given known habitat selection cues, are migrating birds passively intercepted by...

Pheromone mechanisms and behavioral strategies for maximizing courtship success in a terrestrial salamander, Plethodon shermani

Creator:: Vaccaro, Elyse A.
Abstract:: Darwin devised the evolutionary theory of sexual selection to account for the manifold extravagances of courtship behaviors and displays. Mating interactions represent a major evolutionary process driving the elaboration, vibrancy, and peculiarity of these courtship traits. For my dissertation research, I strived to elucidate the dynamics that constitute the complex...

Chemical cues and the molecular basis of olfactory chemoreception in caudate amphibians

Creator:: Kiemnec, Karen M.
Abstract:: Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...

Evolution of a pheromone signaling system in the salamander genus Plethodon (Amphibia: Plethodontidae)

Creator:: Picard, Amy L.
Abstract:: Animal signaling systems frequently utilize multiple traits to produce and transmit a signal. These system elements may span multiple levels of organization. Functional integration of these traits may be expected to generate concordance in evolutionary pattern among system elements, such that evolutionary change in one system component is correlated with...

The Role of Social Networks in Federal Agency Hiring: A Comparison of Employees from Diverse Backgrounds

Creator:: Moreno Luna, Arlyn Yire
Abstract:: Due to past hiring practices U.S. federal agencies have workforces that do not match the diversity of the populations they serve. In 2011, the Partnership for Public Service found that the United States Forest Service (USFS) ranked number 149 out of 206 agencies in the category of ‘Support for Diversity,’...

Genetic and meristic relationships of coastal cutthroat trout (Oncorhynchus clarki clarki) residing above and below barriers in two coastal basins

Creator:: Griswold, Kitty E.
Abstract:: An investigation of the genetic and meristic patterns of coastal cutthroat trout (Oncorhynchus clarki clarki) in two coastal basins, one in Oregon and one in Alaska, revealed varying degrees of differences among populations within each site. Coastal cutthroat trout collected from seven sites above and below barriers from Elk River,...

The Behavioral Responses of Western Toad (Anaxyrus boreas) Larvae to Simultaneous Stressors

Creator:: Reynolds, Emily R.
Abstract:: Animals can be naturally exposed simultaneously to multiple stressors. These include habitat changes, contaminants, diseases, invasive species, parasitism, and predation. Exposure to various combinations of biotic and abiotic stressors may induce behavioral changes that affect the way an individual interacts within its environment.Like other groups of organisms, amphibians are exposed...
