Semlitsch and Wilbur (1988) report accelerated development in the salamander Ambystoma talpoideum in response to an experimental drawdown of water level, which simulates pool drying; however, Wilbur (1987) found that such drawdowns in field conditions are associated with increased variance in temperature, which might also influence development rate.
Recent research (Irscbick and Shaffer 1997, Shaffer and McKnight 1996) has questioned the taxonomic status of Ambystoma tigrinum, suggesting that the eastern tiger salamander is a distinct species separate from the other recognized forms.
