A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)
Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological studies have shown...
Beyond the edge : riparian habitat use and forest management effects on stream salamanders in the southern Appalachian mountains
(University of Missouri--Columbia, 2007)
While there are many types of habitat loss and degradation (e.g., agriculture, land development), many studies have focused on the impacts of logging on wildlife populations and on ecosystem processes. Little information, however, exists...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
I used both demographic modeling and experimental field research to evaluate the role of terrestrial habitat in the population dynamics and conservation of pond-breeding amphibians. I began by using literature data to ...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg ...
Gray treefrog breeding site selection and offspring performance in response to forest management
(University of Missouri--Columbia, 2007)
Amphibian diversity and abundance are generally reduced following clearcut logging. These impacts often last for decades, but little is known about why diversity and abundance are depressed. I examined gray treefrog breeding ...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
Land use is a pervasive form of disturbance affecting natural systems on Earth. My dissertation research is set within the context of a large scale project referred to as Land-use Effects on Amphibian Populations (LEAP), ...
