Unveiling lizard diversity in a semi-arid ecotone: seasonal patterns and trap performance

In the semi-arid region of Piauí, understanding these dynamics requires the use of efficient sampling methods. Therefore, this study - conducted between June 2024 and February 2025 in the municipality of Floriano (PI) - utilized different passive traps.

The study assessed the occurrence of lizard species and their capture using four types of traps: 2-L pitfall traps, 5-L pitfall traps, 2-L PET–PVC traps, and pitfall traps with drift fences. A total of 123 individuals from 9 species were recorded, representing the lizard species captured during the sampling period. The results provide information on lizard occurrence and the performance of different passive capture methods in a transition zone between the Caatinga and the Cerrado, in the semi-arid Northeast of Brazil.
