THE ROLE OF BIOGEOCHEMISTRY AND CLIMATE IN A NEOTROPICAL ANT COMMUNITY
(2017)
Human activities are rapidly changing nutrient availability and climate across the globe, and this trend is predicted to continue. The effect of biogeochemistry on consumer communities is underexplored in the world’s most ...
Landscape structure in a managed forest mosaic of the Southern Appalachian Mountains and its influence on songbirds and small mammals.
(1998)
Forests in the Appalachian Mountains have been severely affected by logging in the past and little old-growth is left. The remaining forests form a heterogeneous mosaic of different forest successions. A concern for ...
Sibling rivalry for milk in northern grasshopper mice (Onychomys leucogaster).
(1999)
This research explores non-aggressive sibling rivalry over milk in a small mammal, the northern grasshopper mouse (Onychomys leucogaster). Food shortages result in sibling rivalry. Pups from the largest litters grew at ...
CONSERVATION, ECOLOGY, AND EVOLUTION OF MIGRATORY BEHAVIOR IN THE PAINTED BUNTING (Passerina ciris)
(2015)
In animal migration studies, determining the migratory connectivity of different species is a crucial step to understand the ecology and evolution of complex behavioral traits as well as to implement effective conservation ...
Theoretical and Empirical Studies on Hierarchical Effects of Size Distributions: Linking the Individual to its Community
(2017-12)
Population and community ecologists often view the world differently based on one assumption: community ecologists often assume that individuals within a population are functionally equivalent; population ecologists focus ...
Cottonmouth (Agkistrodon piscivorus) spatial ecology.
(2005)
Radio-telemetry was used to study spatial ecology of a Cottonmouth (Agkistrodon piscivorus) population in eastern Texas. I examined effects of sex, reproductive state, and body size on spatial use within a riparian habitat. ...
Multi-scale effects of habitat alteration on stream fishes: from genotypes to communities
(2011)
Understanding how evolutionary and ecological processes interact with altered habitats at these various scales will be a major challenge to conservation biologists in the coming decades, and will be crucial for predicting ...
Ecostystem effects of omnivorous fishes in Lake Texoma (Oklahoma-Texas).
(1999)
I examined the potential effects of benthic omnivorous fishes in reservoir ecosystems. In the first chapter, I examined long-term changes in the total fish assemblage of Lake Texoma based on gill net sampling in 1954, ...
