Mono-Oxygenase Activity and Nutritional Ecology of Larvae of the Gypsy Moth, Lymantria Dispar
… differs on oak vs. pine foliage, quantitative nutritional indices were measured for 3rd instar larvae. Significant trends were evident: Efficiency of conversion of digested food is higher in oak vs. pine fed larvae, but pine feeders have higher relative consumption rates than do oak feeders. …

Effects of nitrogen and water on growth, photosynthesis, and leaf properties of deciduous tree species with consequences for gypsy moth herbivory
… the different nitrogen and water regimes, larval nutritional indices changed in a nonlinear and unpredictable manner. In summary, this study indicates that the interactive effects of water and elevated N availability on growth and photosynthetic response may impact competitive interactions between …

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
… responded to the trends observed in the nutritional indices, while levels of total phenols and catechols appeared unimportant. Analyses of total nitrogen in field-collected plants showed a serial reduction with advancing growth stage. The influence of glucosinolate profile on infestation …

Effect of Oil and Natural Gas Development on Survival and Health of White-tailed Deer in the Western Dakotas
<p>Oil and gas development in North Dakota has resulted in the need for information regarding how increased activity has affected white-tailed deer (Odocoileus virginianus) populations. We evaluated white-tailed deer ecology in response to energy development and hypothesized that oil and gas …
