Effects Of Climate Change And Landscape-Scale Forest Management On Avian Communities, Abundance, And Nest Success In The Appalachian Mountains, Hannah L. Clipp
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 …
Population And Migratory Ecology Of Canada Warblers (Cardellina Canadensis) In The Central Appalachian Mountains, West Virginia, Usa, Stephanie H. Augustine
Population And Migratory Ecology Of Canada Warblers (Cardellina Canadensis) In The Central Appalachian Mountains, West Virginia, Usa, Stephanie H. Augustine
Graduate Theses, Dissertations, and Problem Reports
Nearctic-Neotropical migrant birds experience a wide range of environmental conditions throughout their annual cycle; thus, it is particularly challenging to evaluate the spatial factors that may influence population growth. The Canada Warbler (Cardellina canadensis) faces substantial range-wide population declines, but little study has been conducted regarding elements occurring across the entire year that drive demographic rates. The aims of this research are (1) determine the relationship between Canada Warbler population demographic rates and environmental conditions along an elevation gradient in the central Appalachian Mountains and (2) ascertain the nonbreeding season location and migratory routes used by the central …
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Graduate Theses, Dissertations, and Problem Reports
Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …
Avian Occupancy Dynamics And Canada Warbler (Cardellina Canadensis) Environmental Correlates On A Central Appalachian Elevation Gradient In West Virginia, Gordon W. Dimmig
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 …
