Resumo: | ABSTRACT Habitat fragmentation is one of the sources of the global threat to wildlife populations. During the last four decades, urban development in Brazil’s southern coastline has seen considerable growth, fragmenting the habitat of the sand lizard Liolaemus occipitalis Boulenger, 1885, thus threatening it with extinction. In order to assess the influence of urban development on this species, we used tagging and recapture data to study two populations in Brazil’s southern coastline, one in a conserved area rarely subjected to disturbance and the other in an area undergoing different kinds of anthropogenic disturbance. We explored the consequences of this change in the natural landscape by comparing estimates of survival and abundance with Robust Design Model, and the body condition of individuals in both populations with analysis of covariance and variance. Survival of individuals were lower in the disturbed population than in the conserved population. The abundance of this lizard species was similar between populations. The body condition of females was higher in the disturbed area than in the conserved area, while males were similar among populations, but longer (SVL). This study shows how anthropic impacts can affect a population of lizards and the importance of maintaining protected areas and their interconnection to preserve Liolaemus occipitalis. |

Survival of individuals were lower in the disturbed population than in the conserved population. The abundance of this lizard species was similar between populations. The body condition of females was higher in the disturbed area than in the conserved area, while males were similar among populations, but longer (SVL).
