“…An increase in the weight of the thymus shows activation of the immune system. The thymus weight increased when Dwarf ham-sters [Phodopus sungorus (Pallas, 1773)] were exposed to European polecat (Mustela putorius Linnaeus, 1758) odor for 28 days (Feoktistova et al 2007). Zhang et al (2005) and Li et al (2007) suggested that the increased thymus could indicate infection from viruses, bacteria and parasites.…”

Maternal effects play a crucial role in regulating populations of small mammals and anti-predator behaviors of offspring. The present study investigated the effects of maternal stress induced by exposure to predator odors during gestation on the behavioral and physiological responses of offspring in Brandt's vole (Lasiopodomys brandtii). Effects included changes in growth, behaviors, hormone levels in serum, and fosB/ΔfosB mRNA and FosB/ΔFosB protein expression in the hypothalamus. Our results showed that when pregnant voles were exposed to cat and rabbit urine odors for 18 days (1 h/day), the weight of the female offspring decreased; however, the thymus and ovary indices increased, compared with the control group. Male offspring of voles exposed to cat odor spent more time exploring and foraging, and showed a decrease in corticosterone (CORT) compared with voles in the control group. Both fosB/ΔfosB mRNA and FosB/ΔFosB protein expressions were downregulated in the hypothalamus of male offspring in the cat odor-exposed group compared to that in offspring in the control group. However, the mRNA levels of fosB/ΔfosB in the hypothalamus of female offspring did not decrease in response to cat urine odor. Our findings suggested that maternal stress induced by predator odors during gestation restrained the growth of female offspring and increased the duration of exploring and foraging behaviors of male offspring by regulating the HPA axis, which, in turn, reduced the sensitivity of offspring to unfamiliar environments and increased their probability of becoming prey.

“…Changes in parameters such as heart rate, metabolic rate, and corticosterone also indicate a physiological response of prey to predator cues, suggesting increased alertness, stress, or anxiety ( Dell'Omo et al 1994 ; Chabot et al 1996 ; Blanchard et al 1998 ). Therefore, physiological responses to predator odors have been used successfully to quantify animals’ fear of predation in various studies (e.g., Monclús et al 2006a ; Feoktistova et al 2007 ; Mella et al 2010 ).…”

Effects of historically familiar and novel predator odors on the physiology of an introduced prey

Predator odors can elicit fear responses in prey and predator odor recognition is generally associated with physiological responses. Prey species are often more likely to respond to the odor of familiar rather than alien predators. However, predator naïvety in an introduced prey species has rarely been investigated. We examined the physiological response, as shown by changes in ventilatory variables, of an introduced terrestrial herbivore, the European rabbit Oryctolagus cuniculus, in Australia, to the odor of potential predators and to control odors (distilled water and horse), to explore if responses were limited to historical (cat and fox) predators, or extended to historically novel predators (snake and quoll). All odors except distilled water elicited a response, with rabbits showing long-term higher respiratory frequencies and lower tidal volumes after introduction of the odors, indicating an increase in alertness. However, the intensity of the rabbits’ reaction could not be directly linked to any pattern of response with respect to the history of predator–prey relationships. Rabbits exhibited significantly stronger reactions in response to both cat and quoll odors than they did to distilled water, but responses to horse, fox, and snake odor were similar to that of water. Our results show that the introduced rabbit can respond to both historical and novel predators in Australia, and suggest that shared evolutionary history is not necessarily a prerequisite to predator odor recognition.
