Resumo:
The life history of an organism comprises during its life cycle, the pattern of
growth, differentiation, storage and playback. In this work we studied habitat use,
activity period, morphology, thermal ecology, behavioral repertoire and living
area of two species of lizards Tropidurus hispidus and T. semitaeniatus in Patos,
Paraíba, Brazil. The two species of tropidurídeos showed activity peaks at the
same times, but with plenty differentiated, where T. semitaeniatus presented with
greater number of sightings. The Kolmogorov-Smirnov test showed significant
results for differences in activity patterns of T. hispidus and T. semitaeniatus (GL
= 2, Dmax = 0.2192, p <0.0001), however both species were in most sightings
stopped. Regarding the use of habitat, the principal microhabitat used when first
seen for both species was rocky surface. The average body temperature of T.
semitaeniatus was 35.02 ° C ± 1.66, n = 44e of the temperature T. hispidus was
34.53 ± 2.29 0 C, n = 23. 141 sightings were recorded (91 to 149 for T. hispidus
and T. semitaeniatus), so that all observations were made in the dry and sunny
days. These observations totaled 39 behaviors described, performed by both
species and categorized behaviors Trail, Thermoregulation, Exhibitionism,
territorialism, Foraging and Reproductive. Males of both species were larger and
heavier than females. The average home range of T. hispidus was 22.4 ±
15.85m 2, and the average overall displacement was 26.75 ± 19.19m. The size
difference between the sexes living area of T. hispidus can be explained by
sexual size dimorphism present in this species and the need for adult males
establish larger areas to include females in their areas during the breeding
season.
