Lagartos (Squamata lacertilia) de áreas urbanas

Abstract

The Amazon has the greatest richness of lizards among the Brazilian biomes, however, for many localities these values ​​are still underestimated, with regions being undersampled or not sampled. This study locally inventoried lizard species along the urban, rural and forest landscape in the municipality of Tabatinga, Amazonas, Brazil. Data were collected through three complementary sampling methods for recording lizards: Time-Limited Search (P.L.T.), Occasional Encounters (E.O.) and Third Party Photographic Records (R.F.T.). 148 individuals of 28 species of lizards distributed in 11 families were recorded. The Dactyloidae family had the largest number of species with 7 species, followed by the Gymnophthalmidae, Sphaerodactylidae and Tropiduridae families, with four species each, the Teiidae family with three species, and the Alopoglossidae, Gekkonidae, Iguanidae, Mabuychroidae, Phyllodactylidae, with Poly one species each. The P.L.T. it was the one that registered the greatest richness of species with 18 (64.3%), and of these, 7 species were exclusive to this method. The E.O method recorded 14 (50%) species and 7 exclusive species. And the R.F.T. recorded the lowest species richness with 8 (28.5%) and three exclusive species. Just Ameiva a. ameiva was recorded by the three sampling methods. Species richness and abundance of individuals of lizards recorded were expressive and similar to other studies in the Amazon region. Five species of lizards were recorded only for the urban environment, revealing the importance of carrying out studies aimed at surveying species in urbanized areas.
