Temporal relationships between the red fox and the European badger in a Mediterranean protected area

Niche partitioning according to time, space, or resources is the key to interspecific coexistence. Interactions among carnivore species are complex: interference is common, although positive relationships may develop through trophic facilitation. In turn, different behavioral responses to coexistence may be reported, ranging from avoidance to attraction, the outcome of which is highly dependent on the local environmental context. Here, we evaluated the temporal partitioning by analyzing spatiotemporal relationships between the red fox Vulpes vulpes and the European badger Meles meles in a Mediterranean?protected area for three full years, using intensive camera trapping. The two species showed similar temporal activity patterns, with a nocturnal activity and peaks at dawn and dusk. We found a substantial temporal overlap between red fox and badger (Δ > 0.78, on a 0-1 scale). However, we detected some differences in temporal activity patterns across these species and no evidence of interspecific spatiotemporal avoidance. Previous work provided no evidence supporting spatial avoidance among the study species. Our results suggest a role of temporal partitioning at a finer scale during the night to facilitate interspecific coexistence.
