Modeling carbohydrate ballasting by Trichodesmium spp.

Creator:: White, Angelicque E., Spitz, Yvette H., and Letelier, Ricardo M.
Abstract:: We report the development of a numerical model simulating vertical movement of the cyanobacterium Trichodesmium spp. Given a range of physiological parameters derived from the literature, resultant model solutions allow us to explore the ecological significance of vertical migration by Trichodesmium colonies in a stratified oligotrophic oceanic system such as...

Abstract:: Non-structural carbohydrates (NSC) in plant tissue are frequently quantified to make inferences about plant responses to environmental conditions. Laboratories publishing estimates of NSC of woody plants use many different methods to evaluate NSC. We asked whether NSC estimates in the recent literature could be quantitatively compared among studies. We also...

Linking nonstructural carbohydrate dynamics to gas exchange and leaf hydraulic behavior in Pinus edulis and Juniperus monosperma

Creator:: Woodruff, David R., Meinzer, Frederick C., Marias, Danielle E., Sevanto, Sanna, Jenkins, Michael W., and McDowell, Nate G.
Abstract:: Leaf hydraulics, gas exchange and carbon storage in Pinus edulis and Juniperus monosperma, two tree species on opposite ends of the isohydry–anisohydry spectrum, were analyzed to examine relationships between hydraulic function and carbohydrate dynamics. Leaf hydraulic vulnerability, leaf water potential (Wl), leaf hydraulic conductance (Kleaf), photosynthesis (A), stomatal conductance (gs)...

Seasonal carbohydrate dynamics and growth in Douglas-fir trees experiencing chronic, fungal-mediated reduction in functional leaf area

Creator:: Saffell, Brandy J., Meinzer, Frederick C., Woodruff, David R., Shaw, David C., Voelker, Steven L., Lachenbruch, Barbara, and Falk, Kristen
Abstract:: Stored non-structural carbohydrates (NSCs) could play an important role in tree survival in the face of a changing climate and associated stress-related mortality. We explored the effects of the stomata-blocking and defoliating fungal disease called Swiss needle cast on Douglas-fir carbohydrate reserves and growth to evaluate the extent to which...

Assimilate Partitioning in Vitis vinifera During the Reproductive Period

Creator:: Finger, Sarah A. and Candolfi-Vasconcelos, M. Carmo
Abstract:: Objectives of proposed research: 1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning. 2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...

Food deprivation affects vertical distribution and activity of a marine fish in a thermal gradient: potential energy-conserving mechanisms

Creator:: Sogard, Susan M. and Olla, Bori L.
Abstract:: The effects of reduced food availability on the behavior of juvenile walleye pollock Theragra chalcogramma were examined in laboratory experiments designed to test for potential energy-conserving responses. Groups of juvenile fish were held on 1 of 6 ration treatments ranging from ad libitum to near starvation, and then vertical distribution...

Development of Viticultural Practices to Improve Winegrape Performance Experiment II: Effect of Crop Level on Fruit Composition of Pinot noir Grapes [1998-1999]

Creator:: Taylor, Patrick and Candolfi-Vasconcelos, M. Carmo
Abstract:: A broad range of factors influence wine grape quality and manipulation of these factors has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends...

Genetic resources for methane production from biomass described with the Gene Ontology

Creator:: Purwantini, Endang, Torto-Alalibo, Trudy, Lomax, Jane, Setubal, João C., Tyler, Brett M., and Mukhopadhyay, Biswarup
Abstract:: Methane (CH₄) is a valuable fuel, constituting 70–95% of natural gas, and a potent greenhouse gas. Release of CH₄ into the atmosphere contributes to climate change. Biological CH₄ production or methanogenesis is mostly performed by methanogens, a group of strictly anaerobic archaea. The direct substrates for methanogenesis are H₂ plus...
