Abstract
Prey species develop anti-predatory strategies as a response to minimising the risk of being predated. However, how the European rabbit (Oryctolagus cuniculus) adapts to different predator pressure is not fully known. Here, we studied the adaptive anti-predatory responses of European rabbits exposed to different terrestrial predation pressure. To do this, we took advantage of a rabbit translocation programme in the Sierra Norte Natural Park of Sevilla (SW Spain), where rabbits from the same donor population were translocated in plots with and without terrestrial predator exclusion fences (aerial predation was not excluded in any of the plots). This presented an ideal opportunity to observe whether the behaviour of individuals from the same population adapts to situations with different predator pressure; thus, their behaviour was evaluated through direct observations. Although most rabbits were observed close to cover, differences in distance to cover, group size and behaviour were observed between fenced and unfenced plots. Overall, both adult and juvenile rabbits moved further from cover in the unfenced plot than in the fenced plot. Most of the observations in the unfenced plot corresponded to rabbits in pairs or alone; whereas in the fenced plot, rabbits were primarily in pairs or in larger groups. Our findings suggest that in the unfenced plot, rabbits that moved further from cover were often part of larger groups (≥ 4 rabbits); whereas in the fenced plot, it was rabbits in smaller groups (< 4 rabbits). Rabbits in the unfenced plot were alert and running more frequently than rabbits in the fenced one; in the latter, these rabbits were mostly feeding. Other relaxed behaviours such us grooming or resting were more frequent close to cover. In summary, our results highlight rabbits' capacity to promptly adjust behaviour in response to predation risk, exhibiting adaptive anti-predatory responses tailored to different predation pressures. These insights contribute to understanding the nuanced dynamics of prey species' responses to diverse predation scenarios.

Mammalian Biology (formerly Zeitschrift für Säugetierkunde) is an international scientific journal edited by the Deutsche Gesellschaft für Säugetierkunde (German Society for Mammalian Biology). The journal is devoted to the publication of research on mammals. Its scope covers all aspects of mammalian biology, such as anatomy, morphology, palaeontology, taxonomy, systematics, molecular biology, physiology, neurobiology, ethology, genetics, reproduction, development, evolutionary biology, domestication, ecology, wildlife biology and diseases, conservation biology, and the biology of zoo mammals.
