Simulating dynein’s powerstroke using Brownian dynamics

Creator:: Capek, Elliott
Abstract:: Dynein is a motor protein which transports cargo along tracks inside the cell. Like related motor proteins kinesin and myosin, dynein uses cellular energy to take steps with its two foot domains. Unlike kinesin or myosin, dynein’s stepping pattern is highly varied: it can take steps between zero and 60nm...

Convergent diversity and trait composition in temporary streams and ponds

Creator:: Schriever, Tiffany A. and Lytle, David A.
Abstract:: Hydrology is the main environmental filter in aquatic ecosystems and may result in shared tolerances and functional traits among species in disparate ecosystems. We analyzed the associations between taxonomic and functional facets of diversity within aquatic ecosystems (ponds vs. streams) across a hydroperiod gradient (1–365 d) to untangle the hydrologic...

A new species of Bembidion (Ecuadion) from Ecuador (Coleoptera, Carabidae, Bembidiini), with a key to members of the georgeballi species group

Creator:: Maddison, David R. and Toledano, Luca
Abstract:: A new species of ground beetle, Bembidion ricei, is described from the Andes mountains of Ecuador east of Quito. It belongs to the georgeballi species group of subgenus Ecuadion, and is most similar to Bembidion georgeballi. A key to the species of the group is provided.

Phylogeny of minute carabid beetles and their relatives based upon DNA sequence data (Coleoptera, Carabidae, Trechitae)

Creator:: Maddison, David R. and Ober, Karen A.
Abstract:: The phylogeny of ground beetles of supertribe Trechitae is inferred using DNA sequences of genes that code for 28S ribosomal RNA, 18S ribosomal RNA, and wingless. Within the outgroups, austral psydrines are inferred to be monophyletic, and separate from the three genera of true Psydrina (Psydrus, Nomius, Laccocenus); the austral...

Evaluating Paratransgenesis as a Potential Control Strategy for African Trypanosomiasis

Creator:: Medlock, Jan, Atkins, Katherine E., Thomas, David N., Aksoy, Serap, and Galvani, Alison P.
Abstract:: Genetic-modification strategies are currently being developed to reduce the transmission of vector-borne diseases, including African trypanosomiasis. For tsetse, the vector of African trypanosomiasis, a paratransgenic strategy is being considered: this approach involves modification of the commensal symbiotic bacteria Sodalis to express trypanosome-resistance-conferring products. Modified Sodalis can then be driven into...

Genetic Identification of Chinook Salmon: Stock-Specific Distributions of Juveniles along the Washington and Oregon Coasts

Creator:: Teel, David J., Burke, Brian J., Kuligowski, David R., Morgan, Cheryl A., and Van Doornik, Donald M.
Abstract:: We used microsatellite DNA data and genetic stock identification methods to delineate the temporal and spatial distributions of juvenile Chinook Salmon Oncorhynchus tshawytscha occupying coastal habitats extending from central Oregon to northern Washington. Juveniles were collected in trawl surveys conducted during spring, summer, and autumn over 15 years. Distributions (mean...

Ultraviolet Radiation Influences Perch Selection by a Neotropical Poison-Dart Frog

Creator:: Kats, Lee B., Bucciarelli, Gary M., Schlais, David E., Blaustein, Andrew R., and Han, Barbara A.
Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...

Oregon State University Libraries and Press Strategic Agenda for Research Data Services

Creator:: Sutton, Shan, Barber, David, and Whitmire, Amanda L.
Abstract:: The Strategic Agenda for Research Data Services will guide the development of data services at OSU Libraries from January 2013 to June 2014. The Strategic Agenda is informed by best practices in data management at peer universities. Major elements of the Strategic Agenda include an instructional program on data management,...

Mechanistic Insights into Validoxylamine A 7’-Phosphate Synthesis by VldE Using the Structure of the Entire Product Complex

Creator:: Cavalier, Michael C., Yim, Young-Sun, Asamizu, Shumpei, Neau, David, Almabruk, Khaled H., Mahmud, Taifo, and Lee, Yong-Hwan
Abstract:: The pseudo-glycosyltransferase VldE catalyzes non-glycosidic C-N coupling between an unsaturated cyclitol and a saturated aminocyclitol with the conservation of the stereochemical configuration of the substrates to form validoxylamine A 7'-phosphate, the biosynthetic precursor of the antibiotic validamycin A. To study the molecular basis of its mechanism, the three-dimensional structures of...

A Phylogenetic Perspective on the Individual Species- Area Relationship in Temperate and Tropical Tree Communities

Creator:: Yang, Jie, Swenson, Nathan G., Cao, Min, Chuyong, George B., Ewango, Corneille E. N., Howe, Robert, Kenfack, David, Thomas, Duncan, Wolf, Amy, and Lin, Luxiang
Abstract:: Ecologists have historically used species-area relationships (SARs) as a tool to understand the spatial distribution of species. Recent work has extended SARs to focus on individual-level distributions to generate individual species area relationships (ISARs). The ISAR approach quantifies whether individuals of a species tend have more or less species richness...
