Resumo:
The objective of this work was to inventory the fauna of lizards in two areas with different
phytophysiognomies and to analyze the influence of environmental factors on the diversity of
lizards in the Pico do Jabre (Jabre Peak), Maturéia, state of Paraíba. Data collection in the field
occurred through 12 trips (February 2016 - February 2017), totaling 48 days (5016 field/hours).
The methods used for the capture were: pitfall trap (PIT) in two areas (4608 hours); time
constrained audio-visual search (PVLT - 192 man/hours) of diurnal transects in two areas and
216 man/hours of nocturnal transects in three areas and occasional encounter (EO). During the
study, 21 species of lizards were recorded, distributed into 10 families and 19 genera, the time
constrained visual search (16) was the most efficient method, followed by the occasional
encounter (14) and the pitfalls (11). Out of the 21 species found, 17 were collected totaling 83
individuals. The species Ameiva ameiva, Tropidurus hispidus, T. semitaeniatus, Phyllopezus
pollicaris, Gymnodactylus geckoides and Psychosaura agmosticha occurred in the two areas
sampled by PIT, while Salvator merianae, Ameivula ocellifera, Micrablepharus maximiliani,
and Brasiliscincus heathi were registered in area I and Stenoleps ridleyi, Anotosaura vanzolinia,
Coleodactylus meridionalis and Dipoglossus lessonae in area II. The fauna of lizards is similar
to the one found in Serra de Santana, Tenente Laurentino Cruz - RN and in Vale do Catimbau,
Buíque - PE. During the study nine habitats and 21 microhabitats were recorded, the most used
habitats registered were rock and soil species and the microhabitats rock surfaces, litter and
trunk of trees. On the other hand, occupying lianas, cacti and bushes, were little recorded. In
area I, the greatest width niche width for the habitat of the most abundant species was T.
hispidus (0,564), A. ameiva (0,466), while for Area II, the largest niche width for the habitat of
the most abundant species was for T. hispidus (0,717) and P. pollicaris (0,590). The diversity
of lizards in Pico do Jabre is high, despite the impact of pollution and local visitation.
