Mapping Migratory Bird Prevalence Using Remote Sensing Data Fusion

Creator:: Swatantran, Anu, Dubayah, Ralph, Goetz, Scott, Hofton, Michelle, Betts, Matthew G., Sun, Mindy, Simard, Marc, and Holmes, Richard
Abstract:: Background: Improved maps of species distributions are important for effective management of wildlife under increasing anthropogenic pressures. Recent advances in lidar and radar remote sensing have shown considerable potential for mapping forest structure and habitat characteristics across landscapes. However, their relative efficacies and integrated use in habitat mapping remain largely...

Genetic Diversity and Population Parameters of Sea Otters, Enhydra lutris, before Fur Trade Extirpation from 1741–1911

Creator:: Larson, Shawn, Jameson, Ron, Etnier, Michael, Jones, Terry, and Hall, Roberta
Abstract:: All existing sea otter, Enhydra lutris, populations have suffered at least one historic population bottleneck stemming from the fur trade extirpations of the eighteenth and nineteenth centuries. We examined genetic variation, gene flow, and population structure at five microsatellite loci in samples from five pre-fur trade populations throughout the sea...

Spatial and Temporal Variability of Macroinvertebrates in Spawning and Non-Spawning Habitats during a Salmon Run in Southeast Alaska

Creator:: Campbell, Emily Y., Merritt, Richard W., Cummins, Kenneth W., and Benbow, M. Eric
Abstract:: Spawning salmon create patches of disturbance through redd digging which can reduce macroinvertebrate abundance and biomass in spawning habitat. We asked whether displaced invertebrates use non-spawning habitats as refugia in streams. Our study explored how the spatial and temporal distribution of macroinvertebrates changed during a pink salmon (Oncorhynchus gorbuscha) spawning...

Avian Species Richness in Relation to Intensive Forest Management Practices in Early Seral Tree Plantations

Creator:: Jones, Jay E., Kroll, Andrew J., Giovanini, Jack, Duke, Steven D., Ellis, Tana M., and Betts, Matthew G.
Abstract:: •Background: Managers of landscapes dedicated to forest commodity production require information about how practices influence biological diversity. Individual species and communities may be threatened if management practices truncate or simplify forest age classes that are essential for reproduction and survival. For instance, the degradation and loss of complex diverse forest...

Macroalgae Decrease Growth and Alter Microbial Community Structure of the Reef-Building Coral, Porites astreoides

Creator:: Thurber, Rebecca Vega, Burkepile, Deron E., Correa, Adrienne M. S., Thurber, Andrew R., Shantz, Andrew A., Welsh, Rory, Pritchard, Catharine, and Rosales, Stephanie
Abstract:: With the continued and unprecedented decline of coral reefs worldwide, evaluating the factors that contribute to coral demise is of critical importance. As coral cover declines, macroalgae are becoming more common on tropical reefs. Interactions between these macroalgae and corals may alter the coral microbiome, which is thought to play...

Short-term responses of native bees to livestock and implications for managing ecosystem services in grasslands

Creator:: Kimoto, Chiho, DeBano, Sandra J., Thorp, Robbin W., Taylor, Robert V., Schmalz, Heidi, DelCurto, Timothy, Johnson, Tracey, Kennedy, Patricia L., and Rao, Sujaya
Abstract:: Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...

Amino Acid Uptake in Arbuscular Mycorrhizal Plants

Creator:: Whiteside, Matthew D., Garcia, Maria O., and Treseder, Kathleen K.
Abstract:: We examined the extent to which arbuscular mycorrhizal (AM) fungi root improved the acquisition of simple organic nitrogen (ON) compounds by their host plants. In a greenhouse-based study, we used quantum dots (fluorescent nanoparticles) to assess uptake of each of the 20 proteinaceous amino acids by AM-colonized versus uncolonized plants....

Historical Biogeography and Diversification of Truffles in the Tuberaceae and Their Newly Identified Southern Hemisphere Sister Lineage

Creator:: Bonito, Gregory, Smith, Matthew E., Nowak, Michael, Healy, Rosanne A., Guevara, Gonzalo, Cazares, Efren, Kinoshita, Akihiko, Nouhra, Eduardo R., Domınguez, Laura S., Tedersoo, Leho, Murat, Claude, Wang, Yun, Arroyo Moreno, Baldomero, Pfister, Donald H., Nara, Kazuhide, Zambonelli, Alessandra, Trappe, James M., and Vilgalys, Rytas
Abstract:: Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes...

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...
