| 中文摘要 | we examined breeding behavior responses of male root votes (microtus oeconomus) to temporal risk of predation by using acute and chronic exposure to predator odor. the 2 series of exposure experiments provided 2 types of temporal patterns of risk: continuous safety with a brief period of risk and sustained risk with a brief period of safety. male root votes that were acutely exposed to predator odor for i h suppressed their breeding behavior, but bred immediately after exposure to control odor for i h. those chronically exposed to predator odor for 20 days maintained behavioral suppression during the 1-h period of exposure to control odor. acutely exposed males did not change their physiological patterns of breeding, but those chronically exposed to predator odor had reduced testosterone concentration and epididymis index. our results indicate that breeding behavior in a given situation depends on the overall patterns of risk experienced by male root votes, and the acute and chronic stress responses that affect reproduction are responsible for different behavioral responses to the 2 types of temporal patterns of risk. we also discuss the reasons for conflicting results about breeding suppression of votes between previous studies in the laboratory and the field. |
