Phenology and Productivity of C₃ and C₄ Grasslands in Hawaii

Creator:: Pau, Stephanie and Still, Christopher J.
Abstract:: Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by controlling for...

Effect of Testosterone on Neuronal Morphology and Neuritic Growth of Fetal Lamb Hypothalamus-Preoptic Area and Cerebral Cortex in Primary Culture

Creator:: Reddy, Radhika C., Amodei, Rebecka, Estill, Charles T., Stormshak, Fred, Meaker, Mary, and Roselli, Charles E.
Abstract:: Testosterone plays an essential role in sexual differentiation of the male sheep brain. The ovine sexually dimorphic nucleus (oSDN), is 2 to 3 times larger in males than in females, and this sex difference is under the control of testosterone. The effect of testosterone on oSDN volume may result from...

An Evaluation of Putative Sympatric Speciation within Limnanthes (Limnanthaceae)

Creator:: Meyers, Stephen C., Liston, Aaron, and Meinke, Robert
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies within Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Microbial Gene Abundance and Expression Patterns across a River to Ocean Salinity Gradient

Creator:: Fortunato, Caroline S. and Crump, Byron C.
Abstract:: Microbial communities mediate the biogeochemical cycles that drive ecosystems, and it is important to understand how these communities are affected by changing environmental conditions, especially in complex coastal zones. As fresh and marine waters mix in estuaries and river plumes, the salinity, temperature, and nutrient gradients that are generated strongly...

Effects of Dwarf Mistletoe on Stand Structure of Lodgepole Pine Forests 21-28 Years Post-Mountain Pine Beetle Epidemic in Central Oregon

Creator:: Agne, Michelle C., Shaw, David C., Woolley, Travis J., and Queijeiro-Bolaños, Mónica E.
Abstract:: Lodgepole pine (Pinus contorta) forests are widely distributed throughout North America and are subject to mountain pine beetle (Dendroctonus ponderosae) epidemics, which have caused mortality over millions of hectares of mature trees in recent decades. Mountain pine beetle is known to influence stand structure, and has the ability to impact...

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...

Downstream Warming and Headwater Acidity May Diminish Coldwater Habitat in Southern Appalachian Mountain Streams

Creator:: McDonnell, T. C., Sloat, M. R., Sullivan, T. J., Dolloff, C. A., Hessburg, P. F., Povak, N. A., Jackson, W. A., and Sams C.
Abstract:: Stream-dwelling species in the U.S. southern Appalachian Mountains region are particularly vulnerable to climate change and acidification. The objectives of this study were to quantify the spatial extent of contemporary suitable habitat for acid- and thermally sensitive aquatic species and to forecast future habitat loss resulting from expected temperature increases...

Temporal Gene Expression Variation Associated with Eyespot Size Plasticity in Bicyclus anynana

Creator:: Oliver, Jeffrey C., Ramos, Diane, Prudic, Kathleen L., and Monteiro, Antónia
Abstract:: Seasonal polyphenism demonstrates an organism's ability to respond to predictable environmental variation with alternative phenotypes, each presumably better suited to its respective environment. However, the molecular mechanisms linking environmental variation to alternative phenotypes via shifts in development remain relatively unknown. Here we investigate temporal gene expression variation in the seasonally...

Ecoregional Analysis of Nearshore Sea-Surface Temperature in the North Pacific

Creator:: Payne, Meredith C., Brown, Cheryl A., Reusser, Deborah A., and Lee, Henry, II
Abstract:: The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. To better understand present temperature regimes, we assembled a 29-year nearshore time series of mean monthly...

Release of functional peptides from mother's milk and fortifier proteins in the premature infant stomach

Creator:: Nielsen, Soren D., Beverly, Robert L., Underwood, Mark A., and Dallas, David C.
Abstract:: Digestion of milk proteins in the premature infant stomach releases functional peptides; however, which peptides are present has not been reported. Premature infants are often fed a combination of human milk and bovine milk fortifiers, but the variety of functional peptides released from both human and bovine milk proteins remains...
