Spatial and Temporal Variability of Macroinvertebrates in Spawning and Non-Spawning Habitats during a Salmon Run in Southeast Alaska

Creator:: Campbell, Emily Y., Merritt, Richard W., Cummins, Kenneth W., and Benbow, M. Eric
Abstract:: Spawning salmon create patches of disturbance through redd digging which can reduce macroinvertebrate abundance and biomass in spawning habitat. We asked whether displaced invertebrates use non-spawning habitats as refugia in streams. Our study explored how the spatial and temporal distribution of macroinvertebrates changed during a pink salmon (Oncorhynchus gorbuscha) spawning...

Regulation of Motility of Myogenic Cells in Filling Limb Muscle Anlagen by Pitx2

Creator:: Campbell, Adam L., Shih, Hung-Ping, Xu, Jun, Gross, Michael K., and Kioussi, Chrissa
Abstract:: Cells of the ventrolateral dermomyotome delaminate and migrate into the limb buds where they give rise to all muscles of the limbs. The migratory cells proliferate and form myoblasts, which withdraw from the cell cycle to become terminally differentiated myocytes. The myogenic lineage colonizes pre-patterned regions to form muscle anlagen...

How Effective Are DNA Barcodes in the Identification of African Rainforest Trees?

Creator:: Parmentier, Ingrid, Duminil, Jérôme, Kuzmina, Maria, Philippe, Morgane, Thomas, Duncan W., Kenfack, David, Chuyong, George B., Cruaud, Corinne, and Hardy, Olivier J.
Abstract:: Background: DNA barcoding of rain forest trees could potentially help biologists identify species and discover new ones. However, DNA barcodes cannot always distinguish between closely related species, and the size and completeness of barcode databases are key parameters for their successful application. We test the ability of rbcL, matK and...

Flux Balance Analysis with Objective Function Defined by Proteomics Data-Metabolism of Mycobacterium tuberculosis Exposed to Mefloquine

Creator:: Montezano, Daniel, Meek, Laura, Gupta, Rashmi, Bermudez, Luiz E., and Bermudez, José C. M.
Abstract:: We present a study of the metabolism of the Mycobacterium tuberculosis after exposure to antibiotics using proteomics data and flux balance analysis (FBA). The use of FBA to study prokaryotic organisms is well-established and allows insights into the metabolic pathways chosen by the organisms under different environmental conditions. To apply...

Selenium Supplementation Restores Innate and Humoral Immune Responses in Footrot-Affected Sheep

Creator:: Hall, Jean A., Vorachek, William R., Stewart, Whitney C., Gorman, M. Elena, Mosher, Wayne D., Pirelli, Gene J., and Bobe, Gerd
Abstract:: Dietary selenium (Se) alters whole-blood Se concentrations in sheep, dependent upon Se source and dosage administered, but little is known about effects on immune function. We used footrot (FR) as a disease model to test the effects of supranutritional Se supplementation on immune function. To determine the effect of Se-source...

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...

Mapping the Global Emergence of Batrachochytrium dendrobatidis, the Amphibian Chytrid Fungus

Creator:: Olson, Deanna H., Aanensen, David M., Ronnenberg, Kathryn L., Powell, Christopher I., Walker, Susan F., Bielby, Jon, Garner, Trenton W. J., Weaver, George, The Bd Mapping Group, and Fisher, Matthew C.
Abstract:: The rapid worldwide emergence of the amphibian pathogen Batrachochytrium dendrobatidis (Bd) is having a profound negative impact on biodiversity. However, global research efforts are fragmented and an overarching synthesis of global infection data is lacking. Here, we provide results from a community tool for the compilation of worldwide Bd presence...

The Effects of a Novel Hormonal Breast Cancer Therapy, Endoxifen, on the Mouse Skeleton

Creator:: Gingery, Anne, Subramaniam, Malayannan, Pitel, Kevin S., Reese, Jordan M., Cicek, Muzaffer, Lindenmaier, Laurence B., Ingle, James N., Goetz, Matthew P., Turner, Russell T., Iwaniec, Urszula T., Spelsberg, Thomas C., and Hawse, John R.
Abstract:: Endoxifen has recently been identified as the predominant active metabolite of tamoxifen and is currently being developed as a novel hormonal therapy for the treatment of endocrine sensitive breast cancer. Based on past studies in breast cancer cells and model systems, endoxifen classically functions as an anti-estrogenic compound. Since estrogen...

Prey Patch Patterns Predict Habitat Use by Top Marine Predators with Diverse Foraging Strategies

Creator:: Benoit-Bird, Kelly J., Battaile, Brian C., Heppell, Scott A., Hoover, Brian, Irons, David, Jones, Nathan, Kuletz, Kathy J., Nordstrom, Chad A., Paredes, Rosana, Suryan, Robert M., Waluk, Chad M., and Trites, Andrew W.
Abstract:: Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...

Memory effects of climate and vegetation affecting net ecosystem CO2 fluxes in global forests

Abstract:: Forests play a crucial role in the global carbon (C) cycle by storing and sequestering a substantial amount of C in the terrestrial biosphere. Due to temporal dynamics in climate and vegetation activity, there are significant regional variations in carbon dioxide (CO2) fluxes between the biosphere and atmosphere in forests...
