Regional Contingencies in the Relationship between Aboveground Biomass and Litter in the World’s Grasslands

Creator:: O’Halloran, Lydia R., Chu, Chengjin, Bakker, Jonathan D., Davies, Kendi F., Du, Guozhen, Firn, Jennifer, Hagenah, Nicole, Hofmockel, Kirsten S., Knops, Johannes M. H., Li, Wei, Melbourne, Brett A., Borer, Elizabeth T., Morgan, John W., Orrock, John L., Prober, Suzanne M., Stevens, Carly J., Seabloom, Eric W., MacDougall, Andrew S., Cleland, Elsa E., McCulley, Rebecca L., Hobbie, Sarah, Harpole, W. Stan, and DeCrappeo, Nicole M.
Abstract:: Based on regional-scale studies, aboveground production and litter decomposition are thought to positively covary, because they are driven by shared biotic and climatic factors. Until now we have been unable to test whether production and decomposition are generally coupled across climatically dissimilar regions, because we lacked replicated data collected within...

Assessing the Health of the U.S. West Coast with a Regional-Scale Application of the Ocean Health Index

Creator:: Halpern, Benjamin S., Longo, Catherine, Scarborough, Courtney, Hardy, Darren, Best, Benjamin D., Doney, Scott C., Katona, Steven K., McLeod, Karen L., Rosenberg, Andrew A., and Samhouri, Jameal F.
Abstract:: Management of marine ecosystems increasingly demands comprehensive and quantitative assessments of ocean health, but lacks a tool to do so. We applied the recently developed Ocean Health Index to assess ocean health in the relatively data-rich US west coast region. The overall region scored 71 out of 100, with sub-regions...

Current and Future Land Use around a Nationwide Protected Area Network

Creator:: Hamilton, Christopher M., Martinuzzi, Sebastian, Plantinga, Andrew J., Radeloff, Volker C., Lewis, David J., Thogmartin, Wayne E., Heglund, Patricia J., and Pidgeon, Anna M.
Abstract:: Land-use change around protected areas can reduce their effective size and limit their ability to conserve biodiversity because land-use change alters ecological processes and the ability of organisms to move freely among protected areas. The goal of our analysis was to inform conservation planning efforts for a nationwide network of...

Offspring of first-generation hatchery steelhead trout (Oncorhynchus mykiss) grow faster in the hatchery than offspring of wild fish, but survive worse in the wild: Possible mechanisms for inadvertent domestication and fitness loss in hatchery salmon

Creator:: Blouin, Michael S., Wrey, Madeleine C., Bollmann, Stephanie R., Skaar, James C., Twibell, Ronald G., and Fuentes, Claudio
Abstract:: Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values...

Phytophthora Have Distinct Endogenous Small RNA Populations That Include Short Interfering and microRNAs

Creator:: Fahlgren, Noah, Bollmann, Stephanie R., Kasschau, Kristin D., Cuperus, Josh T., Press, Caroline M., Sullivan, Christopher M., Chapman, Elisabeth J., Hoyer, J. Steen, Gilbert, Kerrigan B., Grunwald, Niklaus J., and Carrington, James C.
Abstract:: In eukaryotes, RNA silencing pathways utilize 20-30-nucleotide small RNAs to regulate gene expression, specify and maintain chromatin structure, and repress viruses and mobile genetic elements. RNA silencing was likely present in the common ancestor of modern eukaryotes, but most research has focused on plant and animal RNA silencing systems. Phytophthora...

Quantitative Trait Loci Associated with the Tocochromanol (Vitamin E) Pathway in Barley

Creator:: Graebner, Ryan C., Wise, Mitchell, Cuesta-Marcos, Alfonso, Geniza, Matthew, Blake, Tom, Blake, Victoria C., Butler, Joshua, Chao, Shiaoman, Hole, David J., Horsley, Rich, Jaiswal, Pankaj, Obert, Don, Smith, Kevin P., Ullrich, Steven, and Hayes, Patrick M.
Abstract:: The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of...

Geo-Referenced, Abundance Calibrated Ocean Distribution of Chinook Salmon (Oncorhynchus tshawytscha) Stocks across the West Coast of North America

Creator:: Bellinger, M. Renee, Banks, Michael A., Bates, Sarah J., Crandall, Eric D., Garza, John Carlos, Sylvia, Gil, and Lawson, Peter W.
Abstract:: Understanding seasonal migration and localized persistence of populations is critical for effective species harvest and conservation management. Pacific salmon (genus Oncorhynchus) forecasting models predict stock composition, abundance, and distribution during annual assessments of proposed fisheries impacts. Most models, however, fail to account for the influence of biophysical factors on year-to-year...

Integrated Landscape Assessment Project final report

Creator:: Gaines, Lisa, Hemstrom, Miles, Kagan, Jimmy, and Salwasser, Janine
Abstract:: The Integrated Landscape Assessment Project (ILAP) was a multi-year effort to produce information, maps, and models to help land managers, policy-makers, and others conduct mid- to broad-scale (e.g., watersheds to states and larger areas) prioritization of land management actions, perform landscape assessments, and estimate cumulative effects of management actions for...

Local Variability Mediates Vulnerability of Trout Populations to Land Use and Climate Change

Creator:: Penaluna, Brooke E., Dunham, Jason B., Railsback, Steve F., Arismendi, Ivan, Johnson, Sherri L., Bilby, Robert E., Safeeq, Mohammad, and Skaugset, Arne E.
Abstract:: Land use and climate change occur simultaneously around the globe. Fully understanding their separate and combined effects requires a mechanistic understanding at the local scale where their effects are ultimately realized. Here we applied an individual-based model of fish population dynamics to evaluate the role of local stream variability in...

Ecoregional Analysis of Nearshore Sea-Surface Temperature in the North Pacific

Creator:: Payne, Meredith C., Brown, Cheryl A., Reusser, Deborah A., and Lee, Henry, II
Abstract:: The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. To better understand present temperature regimes, we assembled a 29-year nearshore time series of mean monthly...
