Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
degradation and amphibian declines. Manipulative experiments were conducted to investigate the performance (i.e., growth, survival) of amphibians that metamorphose from chemically-contaminated aquatic breeding sites. The heavy metal cadmium (Cd) was selected...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
-structured demographic models for two pond-breeding amphibian species and used these models to determine the potential effects of a range of core terrestrial habitat areas on population size and persistence. I next carried out field experiments designed to improve model...
Multi-scale investigations of gray treefrong movements: patterns of migration, dispersal, and gene flow
(University of Missouri--Columbia, 2005)
determining microhabitat use. Further, I have demonstrated the effects of matrix composition on the frequency of inter-pond movements and elucidated historical patterns of gene flow across central Missouri. My data indicate that migration through terrestrial...
