Altering phytoplankton growth rates changes their value as food for microzooplankton grazers

Creator:: McBeain, Kelsey A. and Halsey, Kimberly H.
Abstract:: When microzooplankton graze phytoplankton prey, the consumed carbon is partitioned into particulates, dissolved organic carbon (DOC), and CO2. Allocation of prey carbon to these various fates has important consequences for marine ecosystem function. A 2-stage continuous culture system was used to investigate carbon allocation by microzooplankton consuming phytoplankton grown in...

Influence of Nitrogen Fertilizer Rate on Hop Looper

Creator:: Iskra, A. E., Woods, J. L., and Gent, D. H.
Abstract:: Hop looper, Hypena humuli Harris, can cause substantial defoliation and crop damage by feeding on hop leaves and cones. A 4-yr field study conducted in western Oregon evaluated the abundance of hop looper larvae and associated defoliation of leaves on plants fertilized with nitrogen rates ranging from 44.8 to 269...

Pelagibacter metabolism of diatom-derived volatile organic compounds imposes an energetic tax on photosynthetic carbon fixation

Creator:: Thompson, Douglas A., Moore, Eric R., Davie-Martin, Cleo L., Giovannani, Stephen J., and Halsey, Kimberly, H.
Abstract:: Photosynthetic diatoms and marine bacteria contribute about one third of the net primary production in marine environments. Understanding the interactions between these two organisms is potentially important to the over all flow of carbon in the marine ecosystem.

Heavier rumen-reticulum organs in white-tailed deer (Odocoileus virginianus) is consistent with dietary bulk not quality

Creator:: Weckerly, F. W., Bhaskar, G., Duarte, A., Luna, R. S., and Starns, H. D.
Abstract:: The organs that make up the gastrointestinal tract have high energy demands. Therefore, when these organs vary in mass, they should impact metabolic requirements. Mass of the rumen-reticulum organs, the organs that comprise the largest part of the gastrointestinal tract of ruminants, might vary from bulk or nutrient availability of...

Creator:: Burkhardt, Alyssa, Buchanan, Alex, Cumbie, Jason S., Savory, Elizabeth, A., Chang, Jeff H., and Day, Brad
Abstract:: We re-sequenced the Pseudoperonospora cubensis transcriptome to provide the first extensive transcriptome-wide survey of alternative splicing in an obligate biotrophic pathogen during host infection. The libraries from biological replicates of cucumber leaves infected with Ps. cubensis for 2, 3, 4, and 8 days post inoculation (dpi) were re-sequenced using 100-mer...

The Neisseria gonorrhoeae Obg protein is an essential ribosome-associated GTPase and a potential drug target

Creator:: Zielke, Ryszard A., Wierzbicki, Igor H., Baarda, Benjamin I., and Sikora, Aleksandra E.
Abstract:: Background: Neisseria gonorrhoeae (GC) is a Gram-negative pathogen that most commonly infects mucosal surfaces, causing sexually transmitted urethritis in men and endocervicitis in women. Serious complications associated with these infections are frequent and include pelvic inflammatory disease, ectopic pregnancy, and infertility. The incidence of gonorrhea cases remains high globally while...

Perchlorate Exposure Reduces Primordial Germ Cell Number in Female Threespine Stickleback

Creator:: Petersen, Ann M., Earp, Nathanial C., Redmond, Mandy E., Postlethwait, John H., von Hippel, Frank A., Buck, C. Loren, and Cresko, William A.
Abstract:: Perchlorate is a common aquatic contaminant that has long been known to affect thyroid function in vertebrates, including humans. More recently perchlorate has been shown to affect primordial sexual differentiation in the aquatic model fishes zebrafish and threespine stickleback, but the mechanism has been unclear. Stickleback exposed to perchlorate from...

Community Responses to Climate-Related Variability and Disease: The Critical Importance of Long-Term Research

Creator:: Menge, Bruce A., Caselle, Jennifer E., Barth, John A., Blanchette, Carol A., Carr, Mark H., Chan, Francis, Gravem, Sarah, Gouhier, Tarik C., Lubchenco, Jane, McManus, Margaret A., Milligan, Kristen, Novak, Mark, Raimondi, Peter T., Washburn, Libe, and White, J. Wilson
Abstract:: A major goal of the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) has been to understand the impacts of climate change and variability on the coastal ecosystems of the inner shelf of the California Current Large Marine System in particular, and other marine and even nonmarine systems more generally....

Persistent spatial structuring of coastal ocean acidification in the California Current System

Creator:: Washburn, L., Russell, A., Menge, B. A., Hill, T., Cheriton, O., Nielsen, K. J., McManus, M. A., Feely, R. A., Gouhier, T., Byrne, R. H., Friederich, G., Sanford, E., Hacker, S., Chan, F., Blanchette, C. A., Gaylord, B., Barth, J. A., Sevadjian, J., Hofmann, G., and Chavez, F.
Abstract:: The near-term progression of ocean acidification (OA) is projected to bring about sharp changes in the chemistry of coastal upwelling ecosystems. The distribution of OA exposure across these early-impact systems, however, is highly uncertain and limits our understanding of whether and how spatial management actions can be deployed to ameliorate...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...
