Resource selection, predation risk, and population dynamics of woodland caribou
… local extirpations across North America. Human disturbance has caused caribou declines indirectly through changes to apparent competition dynamics within the predator-prey community. Apparent competition occurs as a negative indirect interaction between prey species, mediated by their direct …

Providing a Restoration Framework for Regulated Rivers
… unregulated streams 2. Develop a tool that uses landscape characteristics to predict flow class membership 3. Use the predictive tool or pre-disturbance hydrologic information to classify regulated rivers to natural flow classes 4. Based on class membership, generalize patterns in hydrologic …

Development of graphical user interface tools for optimal fluid management in shale oil and gas operations
… noise, air pollution, water pollution and landscape disturbance. Interactive management tools allow operators to increase water reuse and minimize the environmental risks of hydraulic fracturing. This research entails developing graphical user tools to optimize water management in shale oil …

Wetland Condition Matters: Amphibian Richness and Abundance Change Across Wetland Condition Gradient
… AIC modeling using nutrients, dissolved oxygen, landscape disturbance, presence of predatory fish, the pesticide atrazine, and KY-WRAM scores as model parameters. Results indicated KY-WRAM score explained the majority in species richness, and was an important predictor of abundance for seven …

Development and Application of Vegetation-Based Biomonitoring Criteria for Floodplain Wetlands
… were tested against an independent landscape disturbance assessment to facilitate the development of a plant-based index of biotic integrity (P-IBI). Box plots and stepwise discriminant function analysis were used to identify the metric associations that had the strongest …

Archives of climate variability on Kiritimati: lacustrine, aeolian and remote sensing perspectives
… changes in tropical hydroclimate and test island landscape sensitivity to changes in the hydrologic cycle. For small tropical islands in particular, insight into past and present hydroclimate variability is important, given the strong influence of the tropical Pacific climate on freshwater …

Vegetation-Based Metrics Of Biotic Integrity For Assessing The Ecological Condition Of Wetlands Of Kentucky
… world has significantly declined due to human disturbances. It has been estimated that Kentucky has lost over 80% of its wetland area. In response to these losses occurring across the United States, the Clean Water Act was passed to halt this dramatic decline and to restore the ecological …

Effects of Landscape Disturbances on Autotrophic Processes Within Arkansas Ozark Streams
… and impacted sites before and after the disturbance occurred for the autotrophic processes measured. These results suggest that BMPs were effective at mitigating effects of low levels of NG activity. However, NG activity in the study watersheds was less than in surrounding areas, …
