Group Nesting

We evaluated costs and benefits of group nesting in prairie voles (Microtus ochrogaster) by examining dispersal from communal nests. Nests at which dispersal occurred did not differ in size from those at which no dispersal was recorded, and most animals did not exhibit declines in body mass prior to dispersal. Of those animals which left communal groups that contained at least one potential mate, half left groups at which level of competition for mates was judged to be low as opposed to medium or high. Our data do not support competition for food or mates as important costs of group nesting. One probable cost to individuals living in family groups is lack of mating opportunity; about one-third of all dispersers were from groups composed solely of family members. Several of our findings suggest that energy conservation is not the primary reason for communal nesting in prairie voles. Reductions in winter group size typically did not precipitate dispersal, and most dispersers that settled into a nest in winter joined groups which were smaller than the groups they had left. Dispersal did not increase during snow cover. Benefits of group nesting in natural populations of prairie voles remain to be identified.

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.
