An Evaluation Of Northern Bobwhite Conservation Research: A Call For Large-Scale Studies, Lex J. Gomez, Kelly S. Reyna
An Evaluation Of Northern Bobwhite Conservation Research: A Call For Large-Scale Studies, Lex J. Gomez, Kelly S. Reyna
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) populations have declined throughout the species’ range since the 1960s. Habitat loss and degradation are thought to have largely contributed to this decline by reducing the amount of space and resources required to sustain viable quail populations. Previous studies have attempted to address this issue by focusing on ranch-level management of bobwhites instead of on the effectiveness of large-scale techniques. Here, we review current and historical studies that have facilitated the implementation of management techniques on multiple scales. In doing so, we will also reveal the shortcomings of such studies by highlighting their narrowed …
Long-Term Population Stability In The Greater Red Hills Region Amidst Range-Wide Declines: A Case For Integrated Management, Theron M. Terhune Ii, D. Clay Sisson, William E. Palmer, Shane D. Wellendorf
Long-Term Population Stability In The Greater Red Hills Region Amidst Range-Wide Declines: A Case For Integrated Management, Theron M. Terhune Ii, D. Clay Sisson, William E. Palmer, Shane D. Wellendorf
National Quail Symposium Proceedings
All natural habitats possess inherent conservation value, including the presence of rare or endemic species, provision of ecosystem services, historic landmarks, or resources harvested. Large-scale loss of natural habitats and deterioration of fire-mediated habitats has caused precipitous declines of native fauna and flora in the southeastern US. The role of private landholdings in wildlife and conservation is often underestimated, and consumptive use of wildlife is commonly viewed as counterproductive to sustainability. However, in the Greater Red Hills region (GRH) of north Florida and south Georgia, intentional management for northern bobwhite (Colinus virginianus) on private lands has not only …
The Role Of Joint Ventures In Northern Bobwhite Conservation, Stephen Demaso
The Role Of Joint Ventures In Northern Bobwhite Conservation, Stephen Demaso
National Quail Symposium Proceedings
Partnerships are crucial part of northern bobwhite (Colinus virginianus) conservation. A key principle is that no single entity can effectively address the complex landscape-level conservation issues to sustain populations and their supporting habitats in perpetuity. Joint Ventures (JVs) use a partnership based approach to deliver specific bird population and habitat objectives within their geography. Currently, 7 of the 12 JVs that occur in the North American bobwhite range have bobwhites listed as a priority species. This presentation will cover various topics including: 1) the history of JVs in North America; 2) an overview of the variety of models …
Temperature Assessment On A Reclaimed Surface Mine During Northern Bobwhite Breeding Season: Considerations For Habitat Management, Donald M. Yow, Jeremy P. Orange, John J. Morgan, Gary Sprandel, Danna L. Baxley, Eric Williams
Temperature Assessment On A Reclaimed Surface Mine During Northern Bobwhite Breeding Season: Considerations For Habitat Management, Donald M. Yow, Jeremy P. Orange, John J. Morgan, Gary Sprandel, Danna L. Baxley, Eric Williams
National Quail Symposium Proceedings
Ground-level air temperatures were assessed within 4 distinct habitat areas on a managed reclaimed surface mine at Peabody Wildlife Management Area, Kentucky, 26 June–17 July 2015, during the northern bobwhite (Colinus virginianus) brood season. Habitat consisted of disked and nondisked areas of native grass and an invasive species, sericea lespedeza (Lespedeza cuneata). Disked areas offered more open space for bobwhite mobility and experienced higher average temperatures than nondisked sites. Although statistically significant, differences in air temperature between disked and nondisked areas were likely too small to have practical implications for bobwhite habitat management in Kentucky under …
Progress Of The National Bobwhite Conservation Initiative, Donald F. Mckenzie, John J. Morgan, Thomas V. Dailey
Progress Of The National Bobwhite Conservation Initiative, Donald F. Mckenzie, John J. Morgan, Thomas V. Dailey
National Quail Symposium Proceedings
Northern bobwhites (Colinus virginianus) have declined precipitously over 5 decades because of a decline in habitat, largely a result of agricultural intensification and inadequate management of natural plant succession. In response, quail biologists developed strategic and operational plans, and formed a national partnership of state and federal agencies, bobwhite institutions, non-government organizations, universities and private citizens. The early history of these efforts was reviewed in 2006 at the Sixth National Quail Symposium. Over the past 10 years, exponential growth occurred, including establishment of a home for national bobwhite conservation at the University of Tennessee, and funding from the …
American Black Duck Wintering Dynamics And Dabbling Duck Response To Herbicide Application In Western Tennessee Wetlands, Joshua Matthew Osborn
American Black Duck Wintering Dynamics And Dabbling Duck Response To Herbicide Application In Western Tennessee Wetlands, Joshua Matthew Osborn
Masters Theses
American black duck (Anas rubripes) populations declined throughout North America in the late 20th century. Although the breeding population has since stabilized, research investigating habitat use by black ducks in the Mississippi Flyway is scarce. Impacts of wetland management practices in response to invasive species must also be tested to measure responses to habitat quality by black ducks and other waterfowl. During winters 2011-2013 (December-February), I estimated food biomass, diurnal habitat use, and activities of black ducks in 6 cover types at the Duck River Unit of Tennessee National Wildlife Refuge and Cross Creeks National Wildlife Refuge …
Mussel Survivorship, Growth Rate And Shell Decay Rate In The New River Basin Of Tennessee: An Experimental Approach Using Corbicula Fluminea, Grant Andrew Mincy
Mussel Survivorship, Growth Rate And Shell Decay Rate In The New River Basin Of Tennessee: An Experimental Approach Using Corbicula Fluminea, Grant Andrew Mincy
Masters Theses
The New River Basin (NRB) of Tennessee is home to a number of rare endemic aquatic communities. One such community of particular importance to the area, experiencing a precipitous population decline due to the fouling and pollution of their freshwater systems, is that of freshwater mussels (Bogan 2006). This study in the NRB involves measuring the mortality rates of live Asian clams (Corbicula fluminea) assemblages and the shell decay rates of their death assemblages. This study also examines the decay rates of the native Villosa iris to gather information on molluscan health and the ability of their shells …
Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi
Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi
Doctoral Dissertations
Butternut (Juglans cinerea L.), a lesser-known relative of black walnut (Juglans nigra L.), is a native tree species beneficial for wildlife, valuable for timber, and part of the great diversity of species in the eastern forests of North America. Populations of butternut are being devastated by butternut canker disease, caused by the fungus Sirococcus clavigignenti-juglandacearum (V.M.G. Nair, Kostichka, & Kuntz), which is thought to be introduced to North America. The disease causes multiple branch and stem cankers that eventually girdle trees. Small population sizes, lack of sprouting, and shade intolerance exacerbates the disease and results in permanent losses of butternut …
