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...

Spatial and vertical distribution of the invasive European green crab in a temperate estuarine system

Creator:: Lundeberg, Christopher A. and Weldon, Taylor
Abstract:: The European green crab, Carcinus maenas, is a generalist predator that has established invasive populations throughout the world, including the west coast of North America. In Oregon, strong cohorts of green crabs recruit only during major El Niño events. The goals of this study are to: 1) compare the abundance...

Spatial and vertical distribution of the invasive European green crab, Carcinus maenas, in a temperate estuarine system

Creator:: Lundeberg, Christopher A. and Weldon, Taylor
Abstract:: Carcinus maenas is an invasive marine predator. Its generalist feeding strategies make it one of the most effective invaders. Carcinus maenas has invasive populations throughout the world, and was recently introduced to the west coast of North America. This study looks at the abundance and growth of C. maenas in...

Comparing Metacarcinus magister settlement preferences among the seagrasses Z. marina and Z. japonica

Creator:: Jaco, Erin M. and Heidmann, Sarah
Abstract:: Metacarcinus magister, the Dungeness crab, is a commercially important species on the Pacific Northwest coast as the most profitable fishery in Oregon and an important ecological player as both predator and prey. Understanding the spatial distribution of Dungeness throughout different life history stages is beneficial both ecologically and economically. Zostera...

Changes in coral reef symbiont density during acclimation and stress

Creator:: Ton, Hayden, Dziedzic, Katherine, and Meyer, Eli
Abstract:: Coral reefs have become extremely vulnerable to rising ocean temperatures, with mass bleaching events increasing in frequency and severity. If bleaching events persist annually, models predict that more than 90% of reef species will face long-term degradation. However, recent evidence has shown that corals may be able to thermally acclimate...

Ocean Acidification Leads to Broadening of Crab Predators and Faster Predation Rate on Mussels

Creator:: Corliss, Katherine M., Toner, Miranda M., and Britsch, Melissa
Abstract:: Ocean acidification is caused by the dissolved carbon dioxide in the oceans lowering the amount of free carbonate ions. This is turn, affects the ability of calcifying organisms like mussels to build thick shells to protect against predation. Mussels are often preyed upon by both specialist crabs, like Red Rock...

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...

Intertidal Ecology along the Western Coastlines of the Pacific : Upwelling and Bottom-up Effects in Chile and Oregon

Creator:: Murphy, Christina A.
Abstract:: The coastal regions of Chile and Oregon are some of the most productive ecosystems in the world. The intertidal communities of both areas have been well studied, but much remains to be learned about how those communities are structured over large scales. Here, I explore the upwelling regimes and the...
