Female Dispersal and Inbreeding in the Red-cockaded Woodpecker
… I studied three aspects of the biology of the red-cockaded woodpecker: dispersal of breeding females; the costs, benefits, and frequency of inbreeding; and the effect of inbreeding on natal dispersal. Dispersal of breeding female red-cockaded woodpeckers is strongly associated with inbreeding …

Effects of Military Training Activity on Red-cockaded Woodpecker Demography and Behavior---AND---New Territory Formation in the Cooperatively Breeding Red-cockaded Woodpecker
The red-cockaded woodpecker (Picoides borealis) is a federally endangered species. As such, populations need to be increased in order to achieve recovery goals outlined by the U.S. Fish and Wildlife Service. My thesis is composed of two chapters that represent opposite sides of this issue. The …

Ultimate and Proximate Explanations of Helping Behavior in the Red-cockaded Woodpecker (Picoides borealis)
… own reproduction assist others in raising young. Red-cockaded woodpecker helpers may again future indirect fitness benefits by increasing survival of breeders, who produce offspring related to the helper in the future. Breeder survival may be enhanced because of general benefits of group living, …

The Dynamics of Cavity Excavation and Use by the Red-Cockaded Woodpecker (Picoides Borealis)
… delayed dispersal in the cooperatively breeding red-cockaded woodpecker. The long times required for cavity excavation select for competition over breeding vacancies in established territories and against excavation of cavities in unoccupied habitat. Duration of excavation varies between …

Arthropod assemblages on longleaf pines: a possible link between the red-cockaded woodpecker and groundcover vegetation
… serve as the food base for the federally endangered red-cockaded woodpecker (RCW). In a recent study, this arthropod community has been suggested to be the mechanism by which RCW reproductive success is linked to the groundcover composition of the forest (which is a reflection of the forest's …

Foraging Habitat and Reproductive Success of Red-Cockaded Woodpecker (<em>Picoides borealis</em>) Groups in Southeastern Georgia
… recovery of populations of the federally endangered Red-cockaded Woodpecker (.Picoides borealis). The Technical/Agency Draft Revised Recovery Plan for the Redcockaded Woodpecker (Picoides borealis) (USFWS 2000) sets the most comprehensive guidelines yet available for the management of …

Stress in the Red-cockaded Woodpecker: Hormonal Mechanisms of Reproductive Suppression in Helper Males and Impacts of Military Training Activities
… activities on wildlife. In these studies I measured plasma levels of the stress hormone corticosterone in the endangered red-cockaded woodpecker (Picoides borealis) to determine their role in the reproductive behavior of individuals in this species, and whether they are affected by human …

Experimental study of an avian cavity-nesting community: nest webs, nesting ecology, and interspecific interactions
Cavity-nesting communities are structured by the creation of and competition for cavities as nest-sites. Viewing these communities as interconnected webs can help identify species interactions that influence community structure. This study examines cavity-nesting bird community interactions within …

Pest Management Strategies for Longhorn Army Ammunition Plant and an Assessment of Aerial Radiography for Hazard Rating Pine Stands for Southern Pine Beetle Infestation
… to high infestations of pine tip moth occurred with little associated damage; and annosus root rot was not apparent in the stands. Fusiform rust was evident in the stands but little mortality occurred. Aerial videography at 1,000 feet AGL proved to be adequate for southern pine beetle hazard …

Assessing Habitat Quality for the Endangered Red-cockaded Woodpcker
… Guidelines depict good quality habitat for the red-cockaded woodpecker (Picoides borealis) at Camp Lejeune, NC. To accomplish this, I used multiple linear and logistic regression to examine the relationships between fitness, habitat use, home range size, and habitat characteristics described in …

First- and Second-Order Properties of Spatiotemporal Point Patterns in the Space-Time and Frequency Domains
… of the homerange of groups of the endangered red-cockaded woodpecker in the Fort Bragg area of North Carolina. Monthly or bimonthly point patterns of the bird distribution are analyzed and integrated over a 23 month period.

The Effects of Prescribed Burning by the National Park Service on Pine -Oak Forests Within Great Smoky Mountains National Park
… burning is to create suitable habitat for the red-cockaded woodpecker, a federally endangered species that requires a habitat with open stands possessing mature pines. The effects of prescribed burns on two pine-oak forests were measured and evaluated to determine their effectiveness in …

Intrabrood Dominance Hierarchies in Juvenile Red-Cockaded Woodpeckers: The Role of Early Social Environment On Post-Fledging Survival and Natal Dispersal
Competition among individuals over shared resources reveals asymmetries in quality resulting in the formation of dominance hierarchies. These hierarchies act as a mechanism for social selection by partitioning resources among group-living animals. The following chapters describe my dissertation …

Using Remote Sensing Data to Predict Habitat Occupancy of Pine Savanna Bird Species
… the use of remote sensing technology to predict habitat occupancy for pine savanna species, and 2) use satellite imagery-based models to inform multispecies management in a pine savanna habitat. To meet my objectives, I conducted point count surveys and built predictive models for three …

Characterization of Sites for Native Herbaceous Understory Restoration in West Gulf Coast Longleaf Pine (Pinus palustris) Savannas
… understory species have since been removed or reduced by exotic plants that were introduced and from the reduction in the frequency of both wild and prescribed fires. A diverse layer of understory species can still be seen today, but not often in the historical savanna setting that is desirable …
