- Abstract
In this study, we present the first data on the diet of two sympatric lizard species Psammodromus algirus and Podarcis vaucheri of the Djurdjura Mountains. The analysis of 100 feces (43 Ps. algirus and 57 P. vaucheri) allowed us to identify 560 prey items (254 for Ps. algirus and 312 for P. vaucheri) distributed across 17 operational taxonomic units. Insects were most commonly consumed by both species, but spiders were also preferred by P. vaucheri. The five most commonly ingested categories of prey among insects were: Coleoptera, Hymenoptera, Homoptera, Heteroptera and Orthoptera. During the study period, the interspecific diet overlap was very high (CH = 0.86). But the diet of P. vaucheri (BA = 0.50) was slightly more diversified than that of Ps. algirus (BA = 0.41). The diets of both species were, however, not strongly different. A significant influence of seasonal variation on diet was detected.
