The physiological state of an animal may have a significant impact on its reproductive success because individuals in good body condition are generally considered to be competitively superior to individuals in poor body condition. In this study, we tested if body condition at weaning affected survival and reproduction of prairie voles ( Microtus ochrogaster (Wagner, 1842)) living under ecologically relevant conditions at two different initial population densities. We detected no evidence that better body condition at weaning was associated with either enhanced survival or reproduction. Moreover, genetic analysis of parentage found that mating between males and females was random with respect to body condition. Results of this study indicate body condition at weaning was not a reliable predictor of future survival or reproduction in prairie voles. This may be because body condition at weaning does not accurately forecast the energetic state of prairie voles at later ages, or because other factors have a greater effect on an individual’s survival and reproductive success at the densities observed in this study.

Risk Of Predation

AbstractBehavioral changes that reduce the risk of predation in response to predator-derived odor cues are widespread among mammalian taxa and have received a great deal of attention. Although voles of the genus Microtus are staples in the diet of many mammalian predators, including domestic cats (Felis catus), there are no previous studies on vole space utilization and activity levels in response to odor cues from domestic cats. Therefore, the objective of our study was to investigate responses of adult prairie voles (Microtus ochrogaster) living in semi-natural habitats to odor cues from domestic cat excreta. Contrary to expectations, neither adult males or females showed significant changes in space use or willingness to enter traps in response to cat odors. One hypothesis to explain our results are that prairie voles have not co-evolved with domestic cats long enough to respond to their odors. Other possible explanations include whether levels of odors in the environment were sufficient to trigger a response or that the perceived risk of predation from odor cues alone did not outweigh relative costs of changing space use and activity levels. Future studies should consider multiple factors when determining what cues are sufficient to elicit antipredatory behavior.
