Using Community Gardens To Help Solve the Hunger Crisis in San Diego County, CA

Creator:: Dusek, Daniel
Abstract:: The World Health Organization defines food security as “all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life.” The reality is that one in six Americans are not food secure, even though the US produces enough food to feed its national...

Evaluation and improvement of the Community Land Model (CLM4) in Oregon forests

Creator:: Hudiburg, T. W., Law, B. E., and Thornton, P. E.
Abstract:: Ecosystem process models are important tools for determining the interactive effects of global change and disturbance on forest carbon dynamics. Here we evaluated and improved terrestrial carbon cycling simulated by the Community Land Model (CLM4), the land model portion of the Community Earth System Model (CESM1.0.4). Our analysis was conducted...

Quantifying dissipative beach and vegetated dune morphology with multiple aerial photography systems

Creator:: Conlin, Matthew P.
Abstract:: Sand dunes provide coastal communities critical protection from flooding and erosion, as well as a habitat for a range of species- some threatened or endangered. As such, it is of importance to develop a quantitative understanding of the processes through which these systems evolve at a variety of temporal and...

Quantification of Habitat and Community Relationships among Nearshore Temperate Fishes Through Analysis of Drop Camera Video

Creator:: Easton, Ryan R., Heppell, Selina S., and Hannah, Robert W.
Abstract:: Temperate nearshore reefs along the Pacific coast of North America are highly valuable to commercial and recreational fisheries yet comprise a small fraction of the seabed. Monitoring fisheries resources in this region is difficult; high-relief structural complexity and adverse sea conditions have led to a paucity of information on temperate...

A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...

Adaptive genetic markers discriminate migratory runs of Chinook salmon (Oncorhynchus tshawytscha) amid continued gene flow

Creator:: O'Malley, Kathleen G., Jacobson, Dave P., Kurth, Ryon, Dill, Allen J., and Banks, Michael A.
Abstract:: Neutral genetic markers are routinely used to define distinct units within species that warrant discrete management. Human-induced changes to gene flow however may reduce the power of such an approach. We tested the efficiency of adaptive versus neutral genetic markers in differentiating temporally divergent migratory runs of Chinook salmon (Oncorhynchus...

Nested scales of spatial heterogeneity in juvenile walleye pollock Theragra chalcogramma in the southeastern Bering Sea

Creator:: Benoit-Bird, Kelly J., McIntosh, Neal E., and Heppell, Scott A.
Abstract:: We sought to characterize the distribution of juvenile walleye pollock Theragra chalcogramma in an area of intense predator-prey interactions and to describe habitat features that lead to their observed distributions. The distribution of juvenile walleye pollock around the Pribilof Islands in the southeastern Bering Sea in 2008 and 2009 was...

Selenium Supplementation Restores Innate and Humoral Immune Responses in Footrot-Affected Sheep

Creator:: Hall, Jean A., Vorachek, William R., Stewart, Whitney C., Gorman, M. Elena, Mosher, Wayne D., Pirelli, Gene J., and Bobe, Gerd
Abstract:: Dietary selenium (Se) alters whole-blood Se concentrations in sheep, dependent upon Se source and dosage administered, but little is known about effects on immune function. We used footrot (FR) as a disease model to test the effects of supranutritional Se supplementation on immune function. To determine the effect of Se-source...

Factors affecting female space use in ten populations of prairie chickens

Creator:: Winder, Virginia L., Carrlson, Kaylan M., Gregory, Andrew J., Hagen, Christian A., Haukos, David A., Kesler, Dylan C., Larsson, Lena C., Matthews, Ty W., McNew, Lance B., Patten, Michael A., Pitman, Jim C., Powell, Larkin A., Smith, Jennifer A., Thompson, Tom, Wolfe, Donald H., and Sandercock, Brett K.
Abstract:: Conservation of wildlife depends on an understanding of the interactions between animal movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely...

Multi-scale spatial controls of understory vegetation in Douglas-fir–western hemlock forests of western Oregon, USA

Creator:: Burton, Julia I., Ganio, Lisa M., and Puettmann, Klaus J.
Abstract:: Forest understory vegetation is influenced by broad-scale variation in climate, intermediate-scale variation in topography, disturbance and neighborhood interactions. However, little is known about how these multi-scale controls interact to influence observed spatial patterns. We examined relationships between the aggregated cover of understory plant species (%C[subscript U]) and multi-scale controls using...
