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 …

Lichen Conservation In Eastern North America: Population Genomics, Climate Change, And Translocations, Jessica Allen

Dissertations, Theses, and Capstone Projects

Conservation biology is a scientific discipline that draws on methods from diverse fields to address specific conservation concerns and inform conservation actions. This field is overwhelmingly focused on charismatic animals and vascular plants, often ignoring other diverse and ecologically important groups. This trend is slowly changing in some ways; for example, increasing number of fungal species are being added to the IUCN Red-List. However, a strong taxonomic bias still exists. Here I contribute four research chapters to further the conservation of lichens, one group of frequently overlooked organisms. I address specific conservation concerns in eastern North America using modern methods. …

Predictors Of Exotic Plant Species In United States National Parks, Rachel S. Fried

Honors Theses

Invasive species are recognized as a major threat to biodiversity. Understanding what factors facilitate invasion is of great conservation value, as this will allow for more specific and targeted conservation efforts related to non-native species. Knowledge of factors that contribute to invasion play an important role in conservation of particularly unique habitats, such as the iconic United States National Parks. Though National Parks have some legal protections against some forms of habitat degradation, they are still vulnerable to the introduction of non-natives. The purpose of this study is to characterize species invasion in National Parks and identify what environmental conditions …

Plant Diversity Influences The Structure And Function Of A Restored Prairie And Its Responses To Added Disturbances, Rebecca Bevans

School of Natural Resources: Dissertations, Theses, and Student Research

As global warming, human conversion of natural landscapes to agricultural uses, and widespread biodiversity losses continue to alter the ecosystems we depend on, an understanding of the relationship between ecosystem structure, composition, and function is needed to maintain valuable ecosystem states and their associated functions. Research testing the limits of an ecosystem’s ability to maintain essential structure and functioning under disturbance conditions can aid in this goal.

In this study, I measured the relationship between plant diversity, community structure and functional traits, and their responses to added disturbances. I added disturbances representing those either caused or intensified by human activity …
