Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer
Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
One-way escape gates and earthen escape ramps are structures used to enable deer to exit the highway right-of-way along fenced roads. I compared the use of one-way escape gates and earthen escape ramps by mule deer on two highways in Utah to determine if deer exhibited a preference for either structure. Results showed that earthen escape ramps were used by mule deer 8-11 times more frequently than one-way gates. Highway mortality data suggest that the installation of the escape ramps likely reduced mortality of mule deer in both study locations, because we could not attribute reductions in mortality to decreased …
Natural Succession Of Benthic Populations In Constructed Sediment Ponds And Ditches In Southwestern West Virginia, Robin E. Dolin
Natural Succession Of Benthic Populations In Constructed Sediment Ponds And Ditches In Southwestern West Virginia, Robin E. Dolin
Theses, Dissertations and Capstones
Strip mining causes major disturbances of the natural environment. One such disturbance is the creation of valley fills, which often fill in the headwaters of small streams. Runoff from these valley fills can cause heavy siltation as well as acid and heavy metal deposition downstream. One way to combat this problem is through the construction of sedimentation ponds, which slow down the flow of water so that sediment can settle out and water chemistry can be altered before the water is discharged into the stream. Since these ponds are, in effect, temporarily replacing small headwaters once present, the question is …
Factors Influencing Spatial Variability In Soil Nitrogen (N) Dynamics In N-Treated And Untreated Watersheds Of The Fernow Experimental Forest, West Virginia, Nikki Lenore Lyttle
Factors Influencing Spatial Variability In Soil Nitrogen (N) Dynamics In N-Treated And Untreated Watersheds Of The Fernow Experimental Forest, West Virginia, Nikki Lenore Lyttle
Theses, Dissertations and Capstones
The central Appalachian region of the United States receives some of the highest inputs of nitrogen (N) due to acidic deposition in the nation. It is believed that these high could levels contribute to a decline in forest soils within the next 50 to 70 yrs. This study examines factors that influence spatial variability in N-treated and untreated watersheds of the Fernow Experimental Forest, Parsons, West Virginia. Within each of the two watersheds [WS4 untreated control, > 100 yr.; WS3 N-treated, acidified, clear cut, ~ 31 yr.], two 0.04 ha plots, one high N and one low N, were selected for …
Isolation Effects Of Aquatic Habitat Fragmentation On Greenside (Etheostoma Blennioides) And Fantail (Etheostoma Flabellare) Darters, Rita M. Klein
Isolation Effects Of Aquatic Habitat Fragmentation On Greenside (Etheostoma Blennioides) And Fantail (Etheostoma Flabellare) Darters, Rita M. Klein
Masters Theses
Aquatic habitat fragmentation is defined as the lack of connectivity between upstream and downstream populations and can occur along two gradients, the longitudinal gradient and the lateral gradient. The longitudinal gradient focuses on objects within the stream and is concerned with the disruption of stream flow, which is normally brought about by the presence of dams and bridges. Fragmentation along the lateral gradient, on the other hand, examines factors outside of the stream and is related to any loss or modification of the surrounding riparian zone.
In Illinois within the last 100 years, stream habitats have become increasingly fragmented by …
