| Abstract: | Background Loss of pond habitat is catastrophic to aquatic larval amphibians, but even reduction in the amount of time a breeding site
holds water (hydroperiod) can influence amphibian development and limit reproductive success. Using the landscape variation
of a glacial valley in the Greater Yellowstone Ecosystem as the context for a natural experiment, we examined variation in
growth pattern and life history of the salamander Ambystoma tigrinum melanostictum and determined how these developmental characteristics varied with hydroperiod over several summers. |
