Within-population genetic structure differs between two sympatric sister-species of ectomycorrhizal fungi, Rhizopogon vinicolor and R. vesiculosus

Creator:: Dunham, Susie M., Mujic, Alija Bajro, Spatafora, Joseph W., and Kretzer, Annette M.
Abstract:: Using spatial autocorrelation analysis, we examined the within-population genetic structure of Rhizopogon vinicolor and R. vesiculosus, two hypogeous ectomycorrhizal (EM) species that are sympatric sister taxa known to differ in their clonal structure. We collected 121 sporocarps and 482 tuberculate EM of both species from a 20 ha forest stand...

Which design elements of individual quota fisheries help to achieve management objectives?

Creator:: Melnychuk, Michael C., Essington, Timothy E., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., and Smith, Anthony D. M.
Abstract:: Individual quota (IQ) management systems in commercial marine fisheries are highly diverse, differing in the security, durability and exclusivity of the harvesting privilege and the transferability of quota units. This diversity in the degree of harvest rights may influence the effectiveness of IQ fisheries to meet management objectives. We conducted...

Voluntary Agreements and Private Enforcement of Environmental Regulation

Creator:: Langpap, Christian
Abstract:: This paper focuses on a type of voluntary pollution abatement agreement (VA) in which the regulator offers regulatory relief for the participating firm in exchange for environmental improvements. If the regulator does not have statutory authority to provide regulatory relief, the VA can leave the firm more vulnerable to legal...

Vocal repertoire of the social giant otter

Creator:: Leuchtenberger, Caroline, Sousa-Lima, Renata, Duplaix, Nicole, Magnusson, William E., and Mourão, Guilherme
Abstract:: According to the “social intelligence hypothesis,” species with complex social interactions have more sophisticated communication systems. Giant otters (Pteronura brasiliensis) live in groups with complex social interactions. It is likely that the vocal communication of giant otters is more sophisticated than previous studies suggest. The objectives of the current study...

Variability in expression of anadromy by female Oncorhynchus mykiss within a river network

Creator:: Mills, Justin S., Dunham, Jason B., Reeves, Gordon H., McMillan, John R., Zimmerman, Christian E., and Jordan, Chris E.
Abstract:: We described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss in the John Day River watershed, Oregon. We collected 149 juvenile O. mykiss across 72 sites and identified locations used by anadromous females by assigning maternal origin (anadromous versus non-anadromous) to each juvenile. These assignments used...

Utilizing Fishermen Knowledge and Expertise: Keys to Success for Collaborative Fisheries Research

Creator:: Yochum, Noelle, Starr, Richard M., and Wendt, Dean E.
Abstract:: Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen and scientists. It is a joint intellectual endeavor that begins with the inception of a project and continues until its final stages, with each group having mutual investment in-and ownership of-the project. Collaborative fisheries...

Using Equilibrium Policy Gradients for Spatiotemporal Planning in Forest Ecosystem Management

Creator:: Crowley, Mark
Abstract:: Spatiotemporal planning involves making choices at multiple locations in space over some planning horizon to maximize utility and satisfy various constraints. In Forest Ecosystem Management, the problem is to choose actions for thousands of locations each year including harvesting, treating trees for fire or pests, or doing nothing. The utility...

Urban and rural-residential area land uses in Oregon: a synthesis of an IMST technical workshop on watershed functions and salmonid recovery

Creator:: Independent Multidisciplinary Science Team
Abstract:: On June 21-22, 2011, the Independent Multidisciplinary Science Team (IMST) hosted a technical workshop for local and regional natural resource managers and practitioners in urban and rural-residential land uses. The purpose of the workshop was to discuss management and rehabilitation actions in developed areas that could improve watershed functions, aquatic...

Trace Levels of Fukushima Disaster Radionuclides in East Pacific Albacore

Creator:: Neville, Delvan R., Phillips, A. Jason, Brodeur, Richard D., and Higley, Kathryn A.
Abstract:: The Fukushima Daiichi power station released several radionuclides into the Pacific following the March 2011 earthquake and tsunami. A total of 26 Pacific albacore (Thunnus alalunga) caught off the Pacific Northwest U.S. coast between 2008 and 2012 were analyzed for ¹³⁷Cs and Fukushima-attributed ¹³⁴Cs. Both 2011 (2 of 2) and...
