Activity patterns of aoudad (Ammotragus lervia) in a Mediterranean habitat

Abstract

There is increasing recognition of the occurrence of non-native species that are invasive and potentially contribute to biodiversity loss. A two-year camera trap survey was undertaken on Mountain Mosor, Croatia to determine the daily and seasonal activity patterns of recently introduced non-native aoudad (Ammotragus lervia). Aoudad were most active in open rocky habitats and least active in forest habitats. The effect of habitat on the recorded number of aoudad was significant, while the effects of month and the interaction month × habitat were not. The results showed a typical bimodal activity pattern of aoudad, with a modest peak in activity between 5:00 and 9:00 a.m., and a second, more pronounced activity peak between 5:00 and 7:00 p.m. Since the native habitat of aoudad is similar to that in the Mediterranean region, the inferred range of daily and seasonal activities show that the species is well adapted to the new habitat.
