The quality of relationships in early childhood have lasting effects on children’s academic and behavioral success. Teacher report is the most widely used measure to assess the quality of the teacher-child relationship, however teachers are often biased by the child’s behavior. Observed quality of the relationship may illustrate differences in...
Over 70% of the Antarctic krill population exists along the Antarctic Peninsula, a region undergoing rapid climate change. Recent studies have shown a clear correlation between krill recruitment each spring and the timing and coverage of sea ice the winter before, with less sea ice and a shorter duration being...
Self-directed mobility is a fundamental human right. Typically developing children engage in mobility for a majority of their day, but children with disabilities do not have the same opportunities. Children with disabilities are at a disadvantage and have a greater risk for developmental delays in physical and cognitive skills, along...

When people think of fossils, they generally imagine the bones of large, charismatic animals. However, small mammals are an ecologically important group of organisms that show up frequently in the fossil record, and can frequently function as indicators for local environmental and ecological conditions (Terry, 2007, 2010). Rodent and rabbit...
Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...
The Cinnabar moth, Tyria jacobaeae, has been introduced to North America in an effort to control the invasive plant Jacobaea vulgaris. The Cinnabar moth is the main host of Nosema tyriae. When infection levels are high, N. tyriae can shorten the lifespan and affect reproduction of the Cinnabar moths. The...
Background: Breast cancer is the most common cancer among women. In 2012, over 220,000 women were diagnosed with breast cancer in the United States.

The acquired ability of Salmonella to express varying morphotypes when placed in nutrient-limited conditions is hypothesized to predict increased resistance to food processing interventions. Two of the morphotypes expressed by Salmonella are Red, Dry and Rough (RDAR) and Smooth and White (SAW). Increased resistance is predicted for the RDAR morphotype...
Dibenzo[def,p]chrysene (DBC) is a highly potent, but less prevalent, environmental carcinogen belonging to a class of compounds known as Polycyclic Aromatic Hydrocarbons (PAHs). They are highly ubiquitous and arise as a byproduct of natural and anthropogenic combustion processes. Previous studies have documented carcinogenic effects upon in utero exposure of PAHs....
Mercury (Hg) is a bioaccumulative metal that can threaten the health of wild birds. Feathers are commonly used biomonitoring tools for non-lethally estimating Hg exposure in birds because they contain stable Hg concentrations upon completion of feather growth, when blood flow to the feather has stopped. Despite the common use...
Global human population are growing at a very high rate. By the year 2050, food demand is expected to increase by 70%. World wide 805 million people are malnourished. Entomophagy has the potential to provide a solution to impending hunger problems while taking pressure off of our current cropping systems....
Pseudomonas aeruginosa is an environmental bacterium which
opportunistically infects humans. Commonly residing in irondepleted
environments, P. aeruginosa uses iron-chelating
molecules called siderophores to scavenge iron from its
environment. The most prevalent siderophore used by P.
aeruginosa is known as pyoverdine. After the cell synthesizes and
secretes pyoverdine, the molecule binds...
In 2005, riots spread throughout urban peripheries of large French cities known as banlieues. Once the flames of burning cars and the smoke of teargas dissipated, experts began to question the causes that brought France into a state of emergency. The term banlieue describes suburb tower housing post-World War II...
The discovery of novel compounds with antibacterial properties continues to be critically important.3 One potential source of such compounds is the cryptic genome of fungi known to produce biologically active molecules.

Pome size in relation to seed number and ploidy level was evaluated using Tukeys HSD in R. With 95% confidence, pome diameter was not impacted by seed number in these selections (Tukey’s HSD...
Rural communities face many factors that may contribute to an obesogenic
environment which include poorer food options (highly processed, low cost, and energy dense), reduced physical activity opportunities and resources, increased reliance on automobiles, and social aspects such isolation and neighborhood safety. Sub-optimal school contexts hinder students' healthy eating and...
As bovine parturition nears, the placentome undergoes changes that allow placental delivery within 12 hours after calving. These changes include the expression of enzymatic proteins (e.g. MMPs) within the placentome that are capable of breaking down collagen, allowing for the separation of the cotyledon from the caruncle. Dysregulation of either...
