Subadult male prairie voles were implanted with testosterone in Silastic tubing in an attempt to manipulate aggressive behavior. The implanted voles exhibited a higher level of aggression than either controls or shams in pairwise encounters in a neutral arena. Release rates of testosterone from Silastic tubing were measured in castrated males by radioimmunoassay. Serum testosterone titer of each group of castrated males implanted with three different sized capsules rose to a maximum on the 4th day after implantation and declined to a minimum thereafter. Group mean titers declined in the order of their capsule sizes. It was concluded that implants of testosterone in Silastic tubing are an effective method of increasing aggressiveness in male prairie voles. The possible mode of action of testosterone mediated aggression is discussed.

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.
