Trophic cascades in the western Ross Sea, Antarctica: revisited

Creator:: Ainley, David G., Ballard, Grant, Jones, Randolph M., Jongsomjit, Dennis, Pierce, Stephen D., Smith, Walker O., Jr., and Veloz, Sam
Abstract:: We investigated mesopredator effects on prey availability in the Ross Sea, Antarctica, assessing the reasons why Adélie penguin Pygoscelis adeliae foraging trip duration (FTD) increases and diet changes from krill to fish as numbers of foraging penguins and competing cetaceans increase in the penguins’ foraging area. To investigate penguins’ seasonally...

High-resolution biogeochemical investigation of the Ross Sea, Antarctica, during the AESOPS (U. S. JGOFS) Program

Creator:: Hales, Burke and Takahashi, Taro
Abstract:: The results of high-resolution biogeochemical measurements in the upper 200 m of the Ross Sea, Antarctica, obtained during the AESOPS (U. S. JGOFS) program using the Lamont Pumping SeaSoar (LPS) are presented. They consist of three west-east transects from 170°E to 180° longitude along the AESOPS study line at 76.5°S...

Assimilation of Ship-Mounted ADCP Data for Barotropic Tides: Application to the Ross Sea

Creator:: Erofeeva, S. Y., Padman, Laurie, and Egbert, Gary
Abstract:: The application of a generalized inverse approach for assimilating vessel-mounted acoustic Doppler current profiler (VM-ADCP) data into numerical solutions of barotropic tides is described. The derived estimates of tidal currents can be used to detide the VM-ADCP data and expose underlying mean circulation. The methodology is illustrated with data assimilation...

Little Ice Age climate and oceanic conditions of the Ross Sea, Antarctica from a coastal ice core record

Creator:: Rhodes, R. H., Bertler, N. A. N., Baker, J. A., Steen-Larsen, H. C., Sneed, S. B., Morgenstern, U., and Johnsen, S. J.
Abstract:: Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is made difficult by the scarcity of Southern Hemisphere paleoclimate records. We use a new glaciochemical record of a coastal ice core from...

Factors driving Adélie penguin chick size, mass and condition at colonies of different sizes in the Southern Ross Sea

Creator:: Whitehead, Amy L., Lyver, Phil O'B., Ballard, Grant, Barton, Kerry, Karl, Brian J., Dugger, Katie M., Jennings, Scott, Lescroël, Amelie, Wilson, Peter R., and Ainley, David G.
Abstract:: Body size, mass and condition can affect an organism’s ability to cope with variation in resource availability or metabolic demand, particularly as juveniles reach independence. It follows that changes to parental provisioning efficiency (size and frequency of meals) through intraspecific competition or environmental conditions that affect prey availability may affect...

Flour Quality and Artisan Bread

Creator:: Ross, Andrew S.
Abstract:: A technical definition of artisan breads is proposed, based on the concepts of lean formulations, long fermentations, and the use of process as the primary way to adapt to changing flour qualities. The current status of what constitutes refined flour for artisan bread production is presented and a conclusion drawn...

Evaluating testcross performance and genetic divergence of lines derived from reciprocal tropical maize composites

Creator:: Menkir, Abebe, Kling, Jennifer G., Anjorin, Bamyo, Ladejobi, Funmilayo, and Gedil, Melaku
Abstract:: The development of hybrids with enhanced expression of heterosis depends on the genetic background of the source population and the effectiveness of a breeding scheme used to identify and use divergent inbred lines with good combining ability. The present study was conducted to examine the potential of improved tropical reciprocal...

Characterizing whole-wheat flours produced using a commercial stone mill, laboratory mills, and household single-stream flour mills

Creator:: Ross, Andrew S. and Kongraksawech, Teepakorn
Abstract:: Background and objectives: One hard wheat and one semi-hard wheat were milled on commercial, laboratory, and household-scale flour mills with rotating elements ranging from 0.1 to 1.0 m in diameter and speeds ranging from 65 to 40,000 rpm. The aim of the study was to assess and compare the quality...

Pathogenicity to Douglas-fir of Ophiostoma pseudotsugae and Leptographium abietinum, fungi associated with the Douglas-fir beetle

Creator:: Ross, Darrell W. and Solheim, Halvor
Abstract:: Pole-size Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were inoculated with two fungi (Ophiostoma pseudotsugae (Rumb.) von Arx and Leptographium abietinum (Peck) Wingf.) associated with the Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) to evaluate their pathogenicity. Pruning the lowermost 30% of the live crown had no effect on host tree defenses. Inoculation with...
