Habitat use and movement behavior of Pacific marten (Martes caurina) in response to forest management practices in Lassen National Forest, California

Creator:: Moriarty, Katie M.
Abstract:: Some of the most pressing conservation concerns involve declining populations of species with low fecundity and highly specialized foraging and reproductive requirements. Yet, we often lack a functional understanding of how individuals of those species interact with their environment, specifically how their movement is affected by human-induced changes. In order...

The Influence of Alternate Life History Strategies and Natal Conditions on the Reproductive Performance of Adélie Penguins Breeding on Ross Island, Antarctica

Creator:: Kappes, Peter J.
Abstract:: A fundamental objective of ecology and population biology is to identify factors that drive population dynamics and determine the population-level consequences of their interaction with the environment. Studies of reproductive performance can illuminate population dynamic processes, including the links between organismal biology, the environment, and life history theory. A central...

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)...

Greater Sage-Grouse Demography, Habitat Selection, and Habitat Connectivity in Relation to Western Juniper and its Management

Creator:: Olsen, Andrew C.
Abstract:: The expansion of native, woody plants is a global phenomenon with characteristics and effects that are often indistinguishable from exotic invasions. These expansions have largely been driven by altered fire regimes and favorable climatic conditions. In the Great Basin of western North America, expansion of conifers such as western juniper...

Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Creator:: Johnson, Tracey N.
Abstract:: In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

Piscivorous colonial waterbirds in the Columbia River estuary : demography, dietary contaminants, and management

Creator:: Suzuki, Yasuko
Abstract:: Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus) nest in large colonies on East Sand Island in the Columbia River estuary, the largest known colonies for the two species in the world. Both species of piscivorous colonial waterbirds have been identified as predators with a significant impact on the...

Changing Climate, Changing Contexts : Variation in Rocky Intertidal Predator-prey Interactions Seen Through an Environmental Stress Framework

Creator:: Cerny-Chipman, Elizabeth B.
Abstract:: The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....

Environmental influences on host-pathogen dynamics of the amphibian chytrid fungus

Creator:: Buck, Julia C.
Abstract:: The causes of the global biodiversity crisis are varied and complex. Anthropogenic threats may act in isolation, or interact additively or synergistically with each other or with natural stressors to affect sensitive taxa. The recent emergence of many infectious diseases in wildlife has brought attention to the role of disease...

Missing Out: A Phenomenological Exploration of Chronically Truant, Special Education Students’ Experience of Truancy and School Staff in the Middle Grades

Creator:: Altiero, Holly J.
Abstract:: Chronic truancy and absenteeism are two considerable issues currently facing our youth at increasing rates nationwide. Quantitative research supporting chronic truancy and absenteeism as national problems is abundant (Hendricks, Sale, Evans, McKinley, and Delozier Carter, 2010). Research indicates that students who identify as truant during the middle school grades and...
