Producing and carrying eggs is energetically costly and therefore can affect behavior. Female Southern Red-backed Salamanders (Plethodon serratus) in the Ozarks reproduce biennially, and so during the reproductive season some females are gravid and some are non-gravid. In this study, we compared the exploratory and aggressive behaviors of gravid females, non-gravid females, and males, as well as the escape velocities of each sex class. In exploratory trials, sex did not affect distance travelled, but gravid females and males showed shorter latencies to move than non-gravid females during the winter. During the aggression trials, individuals were subjected to a …
