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 ...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
, Missouri, and South Carolina are determining the effects of timber harvest on the persistence of amphibian populations. The purpose of my dissertation research was to define adult wood frog nonbreeding habitat in continuous oak-hickory forest...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
populations in Missouri.The results of my dissertation research indicate that the quantity and quality of terrestrial habitat available to pond-breeding amphibians can have substantial population level consequences including increased extinction probabilities...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
surveys for three years and used a statistical modeling approach that accounted for the tendency of terrestrial salamanders to be belowground and unavailable for surveys. I found that terrestrial salamander density at our Missouri Ozark study site ranged...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
the physiological processes and body condition of amphibians and other taxa. In the first experiment, southern leopard frog and American toad tadpoles were reared separately in cattle tank mesocosms (1325-L volume) that had been dosed once at 0, 5, 18, 60, or 200...
