Adaptations of the snowy plover, Charadrius alexandrinus, to an inland salt plain /
(The University of Oklahoma., 1974) -
Allelopathic effects of Sporobolus pyramidatus on vegetational patterning /
(The University of Oklahoma., 1970) -
An analysis of selected Oklahoma upland forest stands including both overstory and understory components /
(The University of Oklahoma., 1973) -
An assessment of the effects of zinc, lead, cadmium, and arsenic in soil, vegetation, and water resources surrounding a zinc smelter /
(The University of Oklahoma., 1974) -
A bioecological study of the black-capped vireo (vireo atricapillus) /
(The University of Oklahoma., 1958) -
Breeding and migration ecology of bar-headed goose Anser indicus and swan goose Anser cygnoides in Asia
(2013-12)Most waterfowl that breed in Mongolia, part of the semiarid northern region of East Asia, are long distant migrants. They depend on availability of lake, river, and wetland habitats on their breeding and wintering grounds ... -
CARBON-WATER COUPLING OF TERRESTRIAL ECOSYSTEMS IN RESPONSE TO CLIMATE CHANGE AND CLIMATE VARIABILITY
(2019-05-10)Carbon and water cycles are two fundamental biophysical processes in terrestrial ecosystems. Rain use efficiency (RUE), defined as the ratio of ecosystem productivity to precipitation (PPT), and water use efficiency (WUE), ... -
Community ecology of water-filled tree holes in Panama.
(1999)Water-filled tree holes are phytotelmata formed when rain collects in branch crotches and other wood-lined cavities. Repeated surveys of natural and artificial water-filled tree holes on Barro Colorado Island (BCI), Panama, ... -
Comparative physiology and macroecology of thermal tolerance in ectothermic vertebrates with correlates of phylogeny and biogeography.
(1997)An organism's distribution and geographic range result from physiological tolerances and its ability to adjust physiological processes to maximize survival, growth, and reproduction under a diversity of environmental factors ... -
Correlates of extra-pair paternity and the effects of ectoparasites on nestling growth, parental provisioning and reproductive success in the house sparrow.
(2000)In addition, I looked at another aspect of the reproductive biology of the House Sparrow, the effects of ectoparasites on nestling growth, parental provisioning and reproductive success. To determine whether Pellonyssus ... -
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. ... -
Culture-independent characterization of methane-oxidizing microbial communities in unexplored extreme environments
(2021-08-05)Methane is the second most abundant greenhouse gas in atmosphere. With increasing emissions and more effective in trapping heat than CO2, it contributes up to ~20% of total global warming. Methanotrophs playing a critical ... -
Description and dynamics of some western oak forests in Oklahoma.
(1983)Ordination and classification techniques were used to analyze patterns of forest vegetation, species diversity and soil type in the Wichita Mountains Wildlife Refuge. Cluster analysis based on species composition of the ... -
Differences in nitrate reductase activity between species of different stages in old field succession.
(1982)The ratio of nitrate/ammonium in the soil decreases from a high level in the early stages of old field succession to a low level in the climax in the tall grass prairie region of central Oklahoma. Characteristic species ... -
Distribution and occurrence of carnivores in the Oklahoma panhandle.
(2000)Five carnivore species representing three families were detected sufficiently to permit analysis. Carnivores were, in general, not distributed evenly over regional, landscape and local scales in the panhandle environment. ... -
Drivers of Stream Drying and Network Connectivity Across Spatial Scales
(2024-05-10)Nonperennial streams are widespread and abundant around the globe. Although these streams are societally and ecologically important, they are understudied relative to those that flow continuously. Because of this, we lack ... -
Ecological context and the evolution of mating biases in a freshwater amphipod species complex.
(2007)Mating traits are among the most extravagant traits found in nature. As with any trait, understanding the diversification of mating traits requires information on both direct and indirect selection acting on the traits and ... -
Ecological opportunity and the adaptive diversification of lineages
(2014-12-17)The tenet that ecological opportunity drives adaptive diversification has been central to theories of speciation since Darwin, yet no widely accepted definition or mechanistic framework for the concept currently exists. ... -
The ecology and biogeochemistry of sulfate reduction in the terrestrial subsurface.
(1999)I believe that the ubiquity and importance of sulfate reduction in subsurface environments is a reflection of the diversity of the hydrological and biogeochemical processes which contribute to the availability of sulfate. ...
