traits
The Northern Bobwhite Quail (Colinus virginianus) is an economically
important game bird species that is currently undergoing drastic population
declines throughout its range in the southeast United States of America.
Therefore, there is a critical need to estimate demographic parameters
of survival and reproduction and to identify which parameter and which
factor (habitat fragmentation, extreme weather events, mammalian and avian
predation and hunting pressure) cause these declines. My aims are to estimate
cause-specific mortalities in a northern bobwhite population located in

Research: Population Viability
Analysis for the Florida Panther
The Florida panther (Puma concolor coryi) is a critical endangered
subspecies of cougar that is current restricted to southern Florida. A
scientific review team has recommended a rigorous analysis of data to
estimate demographic parameters and a detailed demographic analysis to
estimate growth and extinction parameters for the panther population.
The goals of my project are: to estimate the survival and reproductive
rates of the Florida panther, to evaluate how these rates are affected
by various factors, to assess the viability of the population of Florida
panthers, and to make recommendations for management and future research
to increase the viability of the panther population.

Research: Effects
of Supplemental Feeding, Predator Exclusion, and Prescribed Fire on Small
Mammal Populations in a Longleaf Pine Ecosystem
Mesomammalian predator removal, supplemental feeding, and prescribed
fire are common management techniques for bobwhite quail. This project
seeks to experimentally examine the effects of these practices on small
mammal populations in a longleaf pine ecosystem.

Research: The increasing interface between humans and endangered mammalian species is one of the primary drivers of population decline in the latter. My research interests are to investigate the dynamics of such ‘human-animal systems’ so as to inform and aid large mammal conservation efforts in the densely populated tropics.
Research Interests: Modeling the dynamics, distribution
and persistence of animal populations, particularly in the light of conservation
of large mammalian fauna.

Research: Population ecology of Drymarchon couperi (Eastern Indigo Snake) in Georgia
The Eastern Indigo Snake, federally listed as threatened since 1978, has been the focus of recent research and conservation efforts across its range in the southeastern United States. In the coastal plain of Georgia and northern Florida, the species is associated primarily with longleaf pine and wiregrass upland communities that support Gopher Tortoises, especially in the fall-winter breeding season. These forests have experienced precipitous declines, with less than 3% of this once-dominant upland habitat remaining. Despite the conservation importance, little is known regarding Indigo Snake population ecology. Therefore, we are using 11 years of mark-recapture records from southeastern Georgia to estimate demographic parameters, factors influencing these parameters, and sensitivities of population growth rates to demographic rates. In addition to informing conservation and management decisions, the relatively intact area used for this study may represent a fairly ideal situation for the species and our results may be particularly valuable for comparison with other populations and restoration efforts.
Research Interests: Resource use of wildlife populations, population ecology, population dynamics, wildlife conservation and management, southeastern United States herpetofauna

Research: Dynamics and Persistence of the Endangered Vancouver Island Marmot Population
The Vancouver Island marmot (Marmota vancouverensis) population has
undergone a drastic decline over the past three decades leaving the species
on the brink of extinction with less than 50 individuals in the wild in
2003. The population has been the focus of population counts starting
in 1972, mark-resighting since 1980 (extensively since 1987), and most
recently, radio-telemetry since 1992. Results from radio-telemetry indicate
that predation is the main source of mortality and the proximate cause
of the population decline. The first goal of my research is to model survival
using both data types simultaneously in order to provide more precise
estimates and also to test hypotheses made possible by the increased sample
size. My research will also include development of matrix models to estimate
population growth and to perform perturbation analyses. With increased
understanding of the population dynamics of the Vancouver Island marmot,
hopefully we can make suggestions for management of the species, including
optimizing strategies for release of captive-bred marmots.

Research: Cooperative breeding in acorn woodpeckers and its population dynamic consequences
I am interested in the effect of behavior on population
dynamics. An interesting behavior seen in roughly 3% of avian species
is cooperative breeding, in which some individuals give up the opportunity
to breed on their own and instead aid in raising the offspring of other
individuals. Acorn woodpeckers in the central coastal region of

Research: Comparison of abundance estimation methods for gopher tortoises
The estimation of the abundance of threatened and endangered species is crucial to our ability to monitor their population status and recovery progress. However, for many species, there is a wide variety of abundance estimation methods available and our knowledge of the accuracy of these methods is incomplete. My work involves analyzing the accuracy and cost effectiveness of different population estimation methods such as line transect distance sampling, double observer sample count and total counts for populations of gopher tortoises (Gopherus polyphemus). A crucial step in gopher tortoise population estimation is the conversion of burrow count estimates to tortoise count estimates. In surveys to determine burrow occupancy, the most common method used is the burrow camera. I am interested in determining occupancy levels of gopher tortoise burrows to obtain an estimate of gopher tortoise populations using burrow cameras and the mark-recapture method.

Research: Metapopulation dynamics of yellow-bellied marmots
Spatial heterogeneity is one of the most common features of
natural populations, and it can also be an important factor influencing
population dynamics. Although there has been a considerable amount of
theoretical investigation in spatial population dynamics, very few were
empirically tested. My research addresses a variety of
questions on the yellow-bellied marmot metapopulation
dynamics and spatially-expilicit population
models in general. The yellow-bellied marmot population in Gothic,
