Fig 3. Prior trapping experience influences the behavioral response to trap confinement in deer mice (Peromyscus maniculatus) and southern red-backed voles (Myodes gapperi).

(a) Deer mice who were naïve to trapping showed a negative relationship between time in the trap and the proportion of time spent in the center portion of the open-field test. Non-naïve mice showed the reverse relationship. (b) Voles who were not naïve to trapping showed a negative relationship between time in the trap and handling time. Plotted are the relationships predicted from the top linear models and raw data points. The variable “time in trap” has been z-standardized, and the variable “prop. time center” is on a logit scale.
