Seed viability studies for recovery of Plagiobothrys hirtus (Boraginaceae), the rough popcornflower

Creator:: Wilson, Courtney, Amsberry, Kelly, and Meinke, Robert J.
Abstract:: Plagiobothrys hirtus is Oregon’s top priority for endangered plant species recovery, and the wetlands of Douglas County provide the only habitat for this plant in the world. The goal is to downlist this species from endangered to threatened, and in order to do that, existing populations must be protected, and...

Development of a 10,000 Locus Genetic Map of the Sunflower Genome Based on Multiple Crosses

Creator:: Bowers, John E., Bachlava, Eleni, Brunick, Robert L., Rieseberg, Loren H., Knapp, Steven J., and Burke, John M.
Abstract:: Genetic linkage maps have the potential to facilitate the genetic dissection of complex traits and comparative analyses of genome structure, as well as molecular breeding efforts in species of agronomic importance. Until recently, the majority of such maps was based on relatively low-throughput marker technologies, which limited marker density across...

Traits, neighbors, and species performance in prairie restoration

Creator:: Wilson, Mark V., Clark, Deborah Louise, 1950-, and Roberts, R. E.
Abstract:: Questions: Are traits related to the performance of plant species in restoration? Are the relationships between traits and performance consistent across the functional groups of annual forbs, perennial forbs, and grasses? Do the relationships between traits and performance depend on neighboring functional groups? Location: A former agricultural field, being restored...

Quantifying the length-scale dependence of surf zone advection

Creator:: Wilson, Greg W., Özkan-Haller, H. Tuba, and Holman, Robert A.
Abstract:: We investigate the momentum balance in the surf zone, in a setting which is weakly varying in the alongshore direction. Our focus is on the role of nonlinear advective terms. Using numerical experiments, we find that advection tends to counteract alongshore variations in momentum flux, resulting in more uniform kinematics....

Models of presence-absence estimate abundance as well as (or even better than) models of abundance: the case of the butterfly Parnassius apollo

Creator:: Gutiérrez, David, Harcourt, Jennifer, Díez, Sonia B., Gutiérrez Illán, Javier, and Wilson, Robert J.
Abstract:: Models relating species distribution records to environmental variables are increasingly applied to biodiversity conservation. Such techniques could be valuable to predict the distribution, abundance or habitat requirements of species that are rare or otherwise difficult to survey. However, despite widely-documented positive intraspecific relationships between occupancy and abundance, few studies have...

Plant traits – a tool for restoration?

Creator:: Clark, Deborah Louise, 1950-, Wilson, Mark V., Roberts, Rachel, Dunwiddie, Peter W., Stanley, Amanda, and Kaye, Thomas N.
Abstract:: Question: Most results of restoration efforts are species-specific and/or site-specific and therefore are not general enough to be easily applied to other species and other sites. Our research addresses the issue of species-specific results by investigating the feasibility of using plant traits instead of taxonomic species to characterize species responses...

Clovis Age Western Stemmed Projectile Points and Human Coprolites at the Paisley Caves

Creator:: Jenkins, Dennis L., Davis, Loren G., Stafford, Thomas W., Jr., Campos, Paula F., Hockett, Bryan, Jones, George T., Cummings, Linda Scott, Yost, Chad, Connolly, Thomas J., Yohe, Robert M., II, Gibbons, Summer C., Raghavan, Maanasa, Rasmussen, Morten, Paijmans, Johanna L. A., Hofreiter, Michael, Kemp, Brian M., Barta, Jodi Lynn, Monroe, Cara, Gilbert, M. Thomas P., and Willerslev, Eske
Abstract:: The Paisley Caves in Oregon record the oldest directly dated human remains (DNA) in the Western Hemisphere. More than 100 high-precision radiocarbon dates show that deposits containing artifacts and coprolites ranging in age from 12,450 to 2295 ¹⁴C years ago are well stratified. Western Stemmed projectile points were recovered in...

A national survey of managed honey bee 2011-12 winter colony losses in the United States: results from the Bee Informed Partnership

Creator:: Spleen, Angela M., Lengerich, Eugene J., Rennich, Karen, Caron, Dewey, Rose, Robyn, Pettis, Jeff S., Henson, Mark, Wilkes, James T., Wilson, Michael, Stitzinger, Jennie, Lee, Kathleen, Andree, Michael, Snyder, Robert, vanEngelsdorp, Dennis, and Bee Informed Partnership
Abstract:: Estimates of winter loss for managed honey bee (Apis mellifera) colonies are an important measure of honey bee health and productivity. We used data from 5,500 US beekeepers (5,244 backyard, 189 sideline and 67 commercial beekeepers) who responded to the April 2012 Bee Informed Partnership Winter Colony Loss Survey and...

Abstract:: This study records the fifth consecutive year that winter losses of managed honey bee (Apis mellifera) colonies in the USA have been around 30%. In April 2011, a total of 5,441 US beekeepers (an estimated 11% of total US beekeepers) responded to a survey conducted by the Bee Informed Partnership....
