Factors Controlling Soil Microbial Biomass and Bacterial Diversity and Community Composition in a Cold Desert Ecosystem: Role of Geographic Scale

Creator:: Van Horn, David J., Van Horn, M. Lee, Barrett, John E., Gooseff, Michael N., Altrichter, Adam E., Geyer, Kevin M., Zeglin, Lydia H., and Takacs-Vesbach, Cristina D.
Abstract:: Understanding controls over the distribution of soil bacteria is a fundamental Understanding controls over the distribution of soil bacteria is a fundamental step toward describing soil ecosystems, understanding their functional capabilities, and predicting their responses to environmental change. This study investigated the controls on the biomass, species richness, and community...

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

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...

Density Can Be Misleading for Low-Density Species: Benefits of Passive Acoustic Monitoring

Creator:: Rogers, Tracey L., Ciaglia, Michaela B., Klinck, Holger, and Southwell, Colin
Abstract:: Climate-induced changes may be more substantial within the marine environment, where following ecological change is logistically difficult, and typically expensive. As marine animals tend to produce stereotyped, long-range signals, they are ideal for repeatable surveying. In this study we illustrate the potential for calling rates to be used as a...

Comparative Composition, Diversity and Trophic Ecology of Sediment Macrofauna at Vents, Seeps and Organic Falls

Creator:: Bernardino, Angelo F., Levin, Lisa A., Thurber, Andrew R., and Smith, Craig R.
Abstract:: Sediments associated with hydrothermal venting, methane seepage and large organic falls such as whale, wood and plant detritus create deep-sea networks of soft-sediment habitats fueled, at least in part, by the oxidation of reduced chemicals. Biological studies at deep-sea vents, seeps and organic falls have looked at macrofaunal taxa, but...

Catching the Right Wave: Evaluating Wave Energy Resources and Potential Compatibility with Existing Marine and Coastal Uses

Creator:: Kim, Choong-Ki, Toft, Jodie E., Papenfus, Michael, Verutes, Gregory, Guerry, Anne D., Ruckelshaus, Marry H., Arkema, Katie K., Guannel, Gregory, Wood, Spencer A., Bernhardt, Joanna R., Tallis, Heather, Plummer, Mark L., Halpern, Benjamin S., Pinsky, Malin L., Beck, Michael W., Chan, Francis, Chan, Kai M. A., Levin, Phil S., and Polasky, Stephen
Abstract:: Many hope that ocean waves will be a source for clean, safe, reliable and affordable energy, yet wave energy conversion facilities may affect marine ecosystems through a variety of mechanisms, including competition with other human uses. We developed a decision-support tool to assist siting wave energy facilities, which allows the...

Climate and Demography Dictate the Strength of Predator-Prey Overlap in a Subarctic Marine Ecosystem

Creator:: Hunsicker, Mary E., Ciannelli, Lorenzo, Bailey, Kevin M., Zador, Stephani, and Stige, Leif Christian
Abstract:: There is growing evidence that climate and anthropogenic influences on marine ecosystems are largely manifested by changes in species spatial dynamics. However, less is known about how shifts in species distributions might alter predator-prey overlap and the dynamics of prey populations. We developed a general approach to quantify species spatial...

Evaluating the Return in Ecosystem Services from Investment in Public Land Acquisitions

Creator:: Kovacs, Kent, Polasky, Stephen, Nelson, Erik, Keeler, Bonnie L., Pennington, Derric, Plantinga, Andrew J., and Taff, Steven J.
Abstract:: We evaluate the return on investment (ROI) from public land conservation in the state of Minnesota, USA. We use a spatially-explicit modeling tool, the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), to estimate how changes in land use and land cover (LULC), including public land acquisitions for conservation, influence...

Predation on an Upper Trophic Marine Predator, the Steller Sea Lion: Evaluating High Juvenile Mortality in a Density Dependent Conceptual Framework

Creator:: Horning, Markus and Mellish, Jo-Ann E.
Abstract:: The endangered western stock of the Steller sea lion (Eumetopias jubatus) - the largest of the eared seals - has declined by 80% from population levels encountered four decades ago. Current overall trends from the Gulf of Alaska to the Aleutian Islands appear neutral with strong regional heterogeneities. A published...

Effect of Feeding Selenium-Fertilized Alfalfa Hay on Performance of Weaned Beef Calves

Creator:: Hall, Jean A., Bobe, Gerd, Hunter, Janice K., Vorachek, William R., Stewart, Whitney C., Vanegas, Jorge A., Estill, Charles T., Mosher, Wayne D., and Pirelli, Gene J.
Abstract:: Selenium (Se) is an essential micronutrient in cattle, and Se-deficiency can affect morbidity and mortality. Calves may have greater Se requirements during periods of stress, such as during the transitional period between weaning and movement to a feedlot. Previously, we showed that feeding Se-fertilized forage increases whole-blood (WB) Se concentrations...
