The use of time and space was analized in a population Teius aculattus. Using the mark-recapture method daily and seasonal activity was studied. Sustrate, cloacal and air temperatures were registered. Home range was measured for three males, three females, two juveniles and one hatching using the convex poligone method. Our conclutions are that time and space are used acording to the trofic strategy of this species (widely foraging) and the thermic parameters are similar to other teids species
