Effects Of Climate Change And Landscape-Scale Forest Management On Avian Communities, Abundance, And Nest Success In The Appalachian Mountains, Hannah L. Clipp

Graduate Theses, Dissertations, and Problem Reports

Birds are integral components of ecosystems and account for billions of dollars in tangible benefits to humans. As such, recent continental declines of bird species have ecological and economic consequences, providing the impetus for my dissertation research. I identified knowledge gaps and proposed novel questions about how birds in the Appalachian Mountains are influenced by changing environmental conditions due to climate change and forest management. The Appalachian Mountains encompass an important biogeographical region with high conservation value due to its myriad habitats and corresponding bird species diversity. Thus, there is a critical need to evaluate the effects of shifting climate …

Small Mammal Communities Of Restored And Natural Wetlands In West Virginia, Krista Noe

Graduate Theses, Dissertations, and Problem Reports

Wetland restoration is commonly practiced as part of conservation programs or wetland mitigation, which attempts to offset human-created losses of natural wetlands. However, because of the intrinsic and human-derived value of wetlands, it is critical to determine whether these wetlands truly act similarly to natural wetlands. One role of wetlands is to provide habitat for a diverse array of wildlife species. Small mammals are often overlooked taxa in wetland restoration efforts. However, they are essential to the wetland system because they influence vegetation and are prey for higher trophic level wildlife. I discuss considerations of restored wetlands, wildlife responses to …

Cerulean Warbler (Setophaga Cerulea) And Associated Species Response To Operational Silviculture In The Central Appalachian Region, Gretchen Emily Nareff

Graduate Theses, Dissertations, and Problem Reports

In this study, I assessed the response of Cerulean Warblers (Setophaga cerulea) and 5 additional songbird species to timber harvests prescribed through operational silviculture. The research took place in relatively contiguous mature deciduous forests in 4 states in the central Appalachian region—Kentucky, Pennsylvania, Virginia, and West Virginia, USA.

For the first part of the study, I collected Cerulean Warbler abundance and territory data through point counts and territory mapping, respectively. I used the point count data to model Cerulean Warbler abundance pre- and post-harvest at 5 study areas (Kentucky [n=1], Virginia [n=2], West Virginia [n=2]) and post-harvest at …

Analysis Of Unconventional Oil And Gas Impacts On Downstream Fish Assemblages And Physiological Stress, Joshua Noah Ankeny

Graduate Theses, Dissertations, and Problem Reports

Unconventional Oil and Gas (UOG) production has been steadily expanding throughout the mid-Atlantic since 2008. Increased sedimentation, degraded water chemistry and an overall decrease in habitat quality due to UOG is anticipated to negatively impact aquatic inhabitants, a common observation in other stressed landscapes (i.e., mining, agriculture, development). We assessed stream health through both community analysis and physiological parameters (i.e., growth and hematocrit). A before-after-control-impact study uncovered three fish metrics that were significantly different following UOG disturbances. The invertivore-piscivore metric decreased following UOG disturbance (p = 0.045) whereas two benthic metrics saw a surprising increase (p = 0.003 and p …

Avian Occupancy Dynamics And Canada Warbler (Cardellina Canadensis) Environmental Correlates On A Central Appalachian Elevation Gradient In West Virginia, Gordon W. Dimmig

Graduate Theses, Dissertations, and Problem Reports

Mountains are important areas for avian diversity and conservation since they have steep elevational and environmental gradients. In the central Appalachian Mountains, several songbird species have trailing edge populations that are restricted to high elevations. Climate change and other factors can cause species distributions to change, which is of particular concern for birds in restricted trailing edge populations. Additionally, the Canada Warbler (Cardellina canadensis) breeds throughout the Appalachian Mountains and is species of conservation concern due to range-wide population declines. For this project, I used avian point count data from the central Appalachian Mountains to: (1) evaluate the …

Distribution And Habitat Use Of Benthic Fishes In The Lower Kanawha River, West Virginia, Nathaniel V. Owens

Graduate Theses, Dissertations, and Problem Reports

The Kanawha River in West Virginia is a historically diverse system in terms of ichthyofauna although, like many other large rivers, it has been subjected to a suite of anthropomorphic perturbations. These include this system being modified to allow the passage of commercial vessels for industry thus altering flow regimes, increased sedimentation, water depth, and channelization, and decreased interactions with its floodplain. Additionally, the fishes of this system have suffered from deleterious historical water quality issues caused by intensive timber operations, mining, and industrial waste. Post Clean Air Act, Clean Water Act, and Surface Mining Control and Reclamation Act water …
