Survivorship of larval Ambystoma maculatum from a single pond varied each year although the variability was not dependent on the number of eggs deposited each year. The survival depends greatly on developmental rates of the larvae, pond duration, and suitable climatic conditions at the time of dispersal. The variations in length of the larval period appear adaptive and cannot be explained by variation in dates of egg deposition. Developmental rates may be altered slightly by environmental factors.
Migrating Ambystoma maculatum tend to utilize the same track on entering and leaving breeding ponds. The movements are usually accom plished at night in rain, fog, or cloudy, weather when visible celestial cues may not be available. The sensory basis for the orienting ability is unknown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
