Abstract

Both species have identical activity rhythms, experience highly similar ambient conditions and maintain body temperatures around identical mean values, but P. sicula regulates its field body temperatures (Tb) more precisely, as indicated by the lower value of the regression slope of Tb on air and substrate temperatures, the lower variance in Tbs, and the absence of diurnal variation in Tbs in the former species. Both species have highly similar thermal preferences. The species differ in microhabitat use: P. tiliguerta was almost exclusively seen on rocks and stone-walls, often at perch heights > 50 cm and at short distances to patches of shade; P. sicula basked on rocky surfaces but foraged on ground in open meadows, often at distances >5 m to deep shade. -from Authors
