The gray bat, Myotis grisescens, in the southwest portion of the Ozark Plateau :
(1980)
To determine the seasonal movements, maternity sites, hibernacula and philopatry of the gray bat, Myotis grisescens, in the southwest portion of the Ozark Plateau, 6858 gray bats were banded at seven locations in Missouri ...
Ecology of Helicopsyche borealis (Hagen) (Trichoptera : helicopsychidae) :
(1984)
The life history and microdistribution of Helicopsyche borealis was compared for a 13-month period in two Oklahoma streams that have different thermal regimes. Densities of H. borealis were usually higher in the thermally ...
The ontogeny of diet in the Mexican spiny-tailed iguana, Ctenosaura pectinata: Physiological mechanisms and ecological consequences.
(1999)
The foraging ecology and digestive physiology of a natural size-structured population of iguanid lizards (Ctenosaura pectinata) was studied through two wet and two dry seasons in a tropical deciduous thorn forest in central ...
Interactions between fishes and zooplankton, with emphasis on an exotic cladoceran, Daphnia lumholtzi, in Lake Texoma, Oklahoma-Texas.
(1997)
Menidia beryllina do utilize the invading cladoceran, Daphnia lumholtzi, as an additional food source. The increase in D. lumholtzi abundance during the middle of the summer, a period when native zooplankton are scarce, ...
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 ...
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. ...
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, ...
Effects of fish density, identity, and species richness on stream ecosystems.
(2005)
Stream ecosystem properties and functions are important because they provide services such as water purification, oxygen production, and carbon fixation that help sustain life. Aquatic organisms can affect these properties ...
