Fear of predators can behaviorally mediate prey population dynamics,
particularly when predation risk influences reproductive investment.
However, the costs of reproductive investment may mitigate predation risk
aversion relative to periods when the link between reproductive output and
prey behavior is weaker. We posit that intensity of reproductive
investment in ungulates may predict their response to predation risk such
that the sexes increase risk exposure during biological seasons that are
pivotal to reproductive success, such as the fawn‐rearing and breeding
seasons for females and males, respectively. We examined the activity
patterns of sympatric white‐tailed deer (Odocoileus virginianus), a
sexually segregated polygynous ungulate, and Florida panthers (Puma
concolor coryi) in the context of the “risky times – risky places
hypothesis” and the reproductive strategy hypothesis. We compared
detection rates and diel activity overlap of both species using
motion‐triggered camera traps positioned on (n = 120) and off (n = 60)
anthropogenic trails across five reproductive seasons. Florida panthers
were nocturnal and primarily observed on‐trail providing an experimental
framework with risky times and risky places. Contrary to studies in other
taxa inversely correlating prey reproductive investment to predation risk,
the sexes of deer were more risk prone during sex‐specific seasons
associated with intense reproductive investment. Our results suggest
spatiotemporally variable predation risk influences sex‐specific
behavioral decision‐making in deer such that reproductive success is
maximized.
