to determine microclimate and thereby influence amphibian survival. Returning to the model building process, I used the results of my field experiments to develop a demographic model designed to evaluate the potential effects of forestry practices on wood frog...

salamanders were significantly less abundant. It is unlikely that salamanders will persist or thrive for more than a season or two in logged forests due to a significant deterioration in body condition of Ocoee salamanders in logged riparian areas. My results...

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), where researchers in Maine...

of floodplain forest restoration on a large, regulated river in an agricultural valley. I used infrared, time-lapse video to identify agriculture-associated nest predators as a primary source of nest mortality in the Sacramento River Valley, California. Then...

on the effects of logging on amphibians that require streams for reproduction. In order to mitigate the impacts of habitat alteration on stream amphibians, it is necessary to have a clear understanding of the role abiotic and biotic factors play in determining...

The movement of individuals within and among populations has been recognized as an important determinant of the persistence of species. Fragmentation of terrestrial landscapes has exacerbated the need to understand the ...

character displacement. Empirical studies of reproductive character displacement often report that the interactions between species are asymmetrical, such that one species shows the expected pattern of displacement while the other does not. This may be a...

Particularly in organisms with a limited breeding period, females must rely on both external and physiological cues to regulate the phenology of reproduction and behavior. I investigated the relationship between male acoustic signals...
