The thermophilic behavior during the postpandrial state is common in Squamata order. However, in species with seasonal activity such as lacerides of arid zones, this pattern in relation to food intake will be different throughout the period of activity. The aim of this study was to compare the selected body temperature (Tsel) in two different conditions of ingest in the psammophilus lizard Liolaemus darwinii. We captured 30 specimens and divided them in two groups, to receive two simultaneous treatments (?feeding?/?fasting?) per 4 days. The Tsel were measured every 30 minutes from 08:00 to 20:00, in a terrarium with linear thermal gradient (25-55°C). Significant differences in Tsel were found in relation to their ingestion state (t(gl=722)=18.51, p
