Ultimate and Proximate Explanations of Helping Behavior in the Red-cockaded Woodpecker (Picoides borealis)
One unresolved issue in the study of cooperative breeding is why individuals that delay their 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 …

The Dynamics of Cavity Excavation and Use by the Red-Cockaded Woodpecker (Picoides Borealis)
Quantification of cavity excavation produced strong empirical support for the ecological constraints model for the evolution of delayed dispersal in the cooperatively breeding red-cockaded woodpecker. The long times required for cavity excavation select for competition over breeding vacancies in …

Foraging Habitat and Reproductive Success of Red-Cockaded Woodpecker (<em>Picoides borealis</em>) Groups in Southeastern Georgia
… 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 Red-cockaded Woodpecker foraging habitat. …

Pest Management Strategies for Longhorn Army Ammunition Plant and an Assessment of Aerial Radiography for Hazard Rating Pine Stands for Southern Pine Beetle Infestation
… as for the endangered red-cockaded woodpecker, Picoides borealis, stands, military installations, or tree farms. The project is stored as a GIS in the Arthur Temple College of Forestry GIS Lab.</p>

Stress in the Red-cockaded Woodpecker: Hormonal Mechanisms of Reproductive Suppression in Helper Males and Impacts of Military Training Activities
… 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 disturbance. In chapter one, I provide an introduction to the vertebrate stress response and I describe …

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 …

Assessing Habitat Quality for the Endangered Red-cockaded Woodpcker
… 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 the guidelines. I assumed …

The fungal communities associated with Red-cockaded Woodpeckers and their excavations: descriptive and experimental evidence of symbiosis
… sites. Endangered red-cockaded woodpeckers (Picoides borealis; RCWs) are the only birds known to solely excavate through the sapwood and into the heartwood of living pine trees and generally take many years to complete their excavations. These birds may have developed a partnership with …

Experimental study of an avian cavity-nesting community: nest webs, nesting ecology, and interspecific interactions
… with hardwoods. Red-cockaded woodpeckers (Picoides borealis) and northern flickers (Colaptes auratus) created most cavities used by other species within this community. In chapter 3, I describe snag densities and nest-site selection of the cavity-nesting bird community at Eglin. Large, …

Intrabrood Dominance Hierarchies in Juvenile Red-Cockaded Woodpeckers: The Role of Early Social Environment On Post-Fledging Survival and Natal Dispersal
… cooperatively breeding red-cockaded woodpecker (Picoides borealis). My research revealed that fledgling red-cockaded woodpeckers form male-biased, linear dominance hierarchies. Among fledgling males,, high relative nestling condition strongly predicted fledgling dominance, and this condition–rank …

Lifetime fitness and changing life history traits in Red-cockaded Woodpeckers
… and managing species. Red-cockaded Woodpeckers (Picoides borealis) are well-studied and provide an ideal system in which to examine ecological and evolutionary questions related to life histories because monitoring them accurately is relatively easy, their behavior is well-described and …

MONITORING SOFT-MAST PRODUCTION IN PINE WOODLAND RESTORATION AREAS ON THE OUACHITA NATIONAL FOREST
… and endangered red-cockaded woodpecker (<em>Picoides borealis</em>). Fire has many potential benefits for wildlife; however, the effects of fire on several important woody soft-mast producing species are not fully understood. Soft-mast quantity and quality is a key component in determining …

Female Dispersal and Inbreeding in the Red-cockaded Woodpecker
Dispersal is a critical life-history component; it determines gene flow and has profound effects on population structure, demography, social systems, and population viability. To add to our knowledge of dispersal and, in particular, our understanding of the relationship between dispersal and …
