Foliar applications of urea-ammonium nitrate (UAN) around anthesis increased seed protein content by about 40% in 1983 and 1984 in 'Scio' barley (Hordeum vulgare L.). In exploring the mode and the mechanism of this increase, agronomic and physiological studies were conducted. The late N applications did not affect yield or...
Direct anthropogenic stressors have caused drastic declines in wildlife populations over the past two centuries. In the face of these threats, spillover of infectious disease from domestic animals and livestock into wildlife, and novel interactions between parasites and pathogens within wildlife communities, have further suppressed already vulnerable populations. As management...
With continual and worldwide human population growth, our impact on the natural environment expands and intensifies every day. We consume natural resources, burn fossil fuels, and release toxic compounds into the air, water, and earth. We build roads that fragment the landscape, construct new settlements, and develop agricultural lands in...
The intricate relationship between wildlife health and the quality of their environment is well established, with technological advances increasing our understanding and aiding the unraveling of underlying mechanisms. Large herbivores require forage of sufficient quality to maintain their condition to reproduce and survive, all while warding off parasites and predators...
American Indians and Alaska Natives have disproportionately high rates of diabetes, and it is not known if perceived medical discrimination is associated with diabetes health measures and poorer health for this population. This study examined the
effect of perceived medical discrimination (PMD) in American Indian women on health care decisions,...
Fecal glucocorticoid metabolites (FGMs) are commonly used as indicators of an animal’s stress response in behavioral and eco-physiological studies. Stress in wild animals represents an immediate measure of the physiological response to changes in the environment, and, potentially, a prospective assessment of the animal’s health and well-being. In wild mammals,...
Polycyclic aromatic hydrocarbons (PAHs) are among the most widely known and studied environmental contaminants, originating from a range of natural and anthropogenic sources. PAHs are known to occur in the environment as complex mixtures, containing both unsubstituted PAHs, as well as a range of PAH derivatives. Among the less-studied of...
The Safe Drinking Water Act ensures that public systems provide water that meets health standards. However, no such protection exists for millions of Americans who obtain water from private wells. Concern for safety is warranted as most wells draw from underground aquifers, and studies demonstrate that groundwater is affected by...
Resilience-based management in rangelands implies maintaining desirable ecological states and avoiding thresholds to less desirable ones; however, the efficacy of resilience-based management depends upon several driving forces. These forces include management by those who depend upon rangelands for their livelihoods, the current state of ecological health of rangelands, and changing...
Prostate cancer risk is significantly lower in Asian countries compared to the US, which has prompted interest in the chemo-preventative action of dietary components such as soy and green tea commonly found in Asian diets, such as soy and green tea. Studies have suggested that soy isoflavones and green tea...
