Genetic characterization of a reptilian calicivirus (Cro1)

Creator:: Sandoval-Jaime, Carlos, Parra, Gabriel I., Smith, Alvin W., Green, Kim Y., and Sosnovtsev, Stanislav V.
Abstract:: Background: Vesiviruses in the family Caliciviridae infect a broad range of animal hosts including mammals, birds, fish, amphibians and reptiles. The vesivirus Cro1 strains were isolated from diseased snakes in the San Diego zoo in 1978 and reported as the first caliciviruses found in reptiles. The goal of this study...

Diffusion of a single-phase fluid through a general deterministic partially-fissured medium

Creator:: Nguetseng, Gabriel, Showalter, Ralph E., and Woukeng, Jean Louis
Abstract:: The sigma convergence method was introduced by G. Nguetseng for studying deterministic homogenization problems beyond the periodic setting and extended by him to the case of deterministic homogenization in general deterministic perforated domains. Here we show that this concept can also model such problems in more general domains. We illustrate...

30-Arcsecond monthly climate surfaces with global land coverage

Creator:: Mosier, Thomas M., Hill, David F., and Sharp, Kendra V.
Abstract:: Monthly total precipitation and mean temperature climate surfaces, gridded to 30-arcseconds (≈1 km at the equator) and available for all global land areas, are presented. These datasets are generated with a Delta downscaling method, using the 30-arcsecond WorldClim climatologies to scale monthly anomaly grids. For monthly mean temperature, the anomalies...

Peroxiredoxins in Parasites

Creator:: Gretes, Michael C., Poole, Leslie B., and Karplus, P. Andrew
Abstract:: Significance: Parasite survival and virulence relies on effective defenses against reactive oxygen and nitrogen species produced by the host immune system. Peroxiredoxins (Prxs) are ubiquitous enzymes now thought to be central to such defenses and, as such, have potential value as drug targets and vaccine antigens. Recent Advances: Plasmodial and...

Dynamics of a recovering Arctic bird population: the importance of climate, density dependence, and site quality

Creator:: Bruggeman, Jason E., Swem, Ted, Andersen, David E., Kennedy, Patricia L., and Nigro, Debora
Abstract:: Intrinsic and extrinsic factors affect vital rates and population-level processes, and understanding these factors is paramount to devising successful management plans for wildlife species. For example, birds time migration in response, in part, to local and broadscale climate fluctuations to initiate breeding upon arrival to nesting territories, and prolonged inclement...

Effects of Ground Failure on Bridges, Roads, and Railroads

Creator:: Ledezma, Christian, Hutchinson, Tara, Ashford, Scott A., Moss, Robb, Arduino, Pedro, Bray, Jonathan D., Olson, Scott, Hashash, Youssef M. A., Verdugo, Ramon, Frost, David, Kayen, Robert, and Rollins, Kyle
Abstract:: The long duration and strong velocity content of the motions produced by the 27 February 2010 Maule earthquake resulted in widespread liquefaction and lateral spreading in several urban and other regions of Chile. In particular, critical lifeline structures such as bridges, roadway embankments, and railroads were damaged by ground shaking...

Summer surface waters in the Gulf of California: Prime habitat for biological N₂ fixation

Creator:: White, Angelicque E., Prahl, Fredrick G., Letelier, Ricardo M., and Popp, Brian N.
Abstract:: We report significant rates of dinitrogen (N₂) fixation in the central basins of the Gulf of California (GC) during July–August 2005. Mixing model estimates based upon δ¹⁵N values of particulate matter in the surface mixed layer indicate that N₂ fixation provides as much as 35% to 48% of the phytoplankton-based...

Defenses of Susceptible and Resistant Chinook Salmon (Onchorhynchus tshawytscha) Against the Myxozoan Parasite Ceratomyxa shasta

Creator:: Bjork, Sarah J., Zhang, Yong-An, Hurst, Charlene N., Alonso-Naveiro, Maria E., Alexander, Julie D., Sunyer, J. Oriol, and Bartholomew, Jerri L.
Abstract:: We investigated intra-specific variation in the response of salmon to infection with the myxozoan Ceratomyxa shasta by comparing the progress of parasite infection and measures of host immune response in susceptible and resistant Chinook salmon Oncorhynchus tshawytscha at days 12, 25 and 90 post exposure. There were no differences in...

Tapeworm Eggs in a 270 Million-Year-Old Shark Coprolite

Creator:: Dentzien-Dias, Paula C., Poinar, George, Jr., de Figueiredo, Ana Emilia Q., Pacheco, Ana Carolina L., Horn, Bruno L. D., and Schultz, Cesar L.
Abstract:: Remains of parasites in vertebrates are rare from the Mesozoic and Paleozoic. Once most parasites that live in - or pass through - the gastrointestinal tract of vertebrates, fossil feces (coprolites) or even intestinal contents (enterolites) can eventually preserve their remains. Here we announce the discovery of a spiral shark...
