Fifty years of change in a Pacific Northwest winter forest bird community

Creator:: Clements, Nolan
Abstract:: North American bird populations have declined throughout the past half century. The majority of studies quantifying these declines have focused on spring and summer breeding birds; not the season of scarcity, winter. We re-surveyed 7 large study plots in Douglas fir forests initially surveyed in winter during the late 1960s...

Assessing how morphology of female desert bighorn sheep varies with climate in the Mojave Desert of California

Creator:: Torres, Jose A.
Abstract:: Understanding how spatial variation in climate correlates with phenotypic variation among individuals may offer insights about local adaptation, population performance, and species’ response to climate change. Desert bighorn sheep (Ovis canadensis nelsoni) in the Mojave Desert of southern California experience a broad range of temperature and aridity, inhabiting mountain ranges...

Population dynamics and conservation biology of Lupinus sulphureus ssp. kincaidii (Fabaceae)

Creator:: Erhart, Teman
Abstract:: Kincaid's lupine (Lupinus sulphureus ssp. kincaidii [Smith] Phillips) is a federally listed Threatened plant of Willamette Valley prairies. Both low reproduction, due to seed coat dormancy, and competition from invasive plants may threaten the longterm viability of this species. In separate studies, I investigated seed germination and an invasive species...

The Mathematics of Critical Shifts in Ecological Networks with Alternative Stable State Theory, A Potential Framework for Early Warning Indicators

Creator:: Kupperman, Michael D.
Abstract:: A long running problem in mathematical biology is the prediction of extinction events, a specialized case of the larger global stability problem found in differential equations and dynamical systems theory. A central technical question is how to introduce the randomness observed in real ecological systems not accounted for in deterministic...

Tracking the Changes: An Exploration of Ecological Succession in Rocky Intertidal Communities

Creator:: Anderson, Roy K., Bachhuber, Silke M., Poirson, Brittany N., and Menge, Bruce A.
Abstract:: The rocky shores of the US West Coast are home to diverse ecological communities made up of species that are uniquely adapted for survival at the harsh boundary between land and sea. Even so, physical or environmental stressors regularly kill swaths of animals on the rocks. This is called disturbance....

Social Aspects of Federal Fisheries Management in the Pacific Islands Region : Stakeholder Perspectives and an Informal Gap Analysis of Current Data

Creator:: Pickering, Emily A.
Abstract:: Information about social and economic attributes of fisheries, fishing communities, and fishery participants is important for marine resource management because the focuses of agency efforts are on managing society's impacts to the marine environment. This thesis addresses two questions. First, what are the perspectives of managers, scientists, and commercial and...

An analysis of the impacts extractive industries have on African ape conservation and community development - trends towards community involvement in conservation

Creator:: Vise, Ruby S.
Abstract:: Primate populations are declining in number, with an estimated “60% of primate species threatened with extinction from hunting and trapping” (Estrada et al., 2017). The largest threat to mammals in West and Central Africa is commercial hunting (Jost Robinson, Daspit, & Remis, 2011). Hunting these large mammals was once practiced...

How sweet is the land? Modeling caloric landscapes for tropical hummingbirds

Creator:: Birkett, Christina Nozomi and Birkett, Nozomi Fukui
Abstract:: Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...
