Popis:	The large psammodromus, Psammodromus algirus, is one of the most widespread Mediterranean lacertid lizards; unfortunately, its ecology in North Africa remains understudied. In this study, we present detailed data on trophic ecology, daily activity patterns during the breeding season, and the maximum activity period of this lizard in a semi-arid environment at Belezma National Park (Batna, northeast Algeria). Feeding data were collected using stomach flushing, and daily activity patterns were analyzed by surveying standardized transects. Analysis of the contents of 21 stomachs revealed 238 prey items of 74 different taxa classified into five classes, 18 orders, 50 families, and 71 different genera. The diet was highly diverse and primarily consisted of arthropods. Insects were the predominant food comprising 85% of all prey, followed by arachnids (13%). Regarding temporal variation in diet, prey-species richness did not vary noticeably between months; however, the number of individuals within prey ...
