The study determined the use of microenvironments (phytotelmata) as a survival strategy for amphibians and reptiles susceptible to climate change at the Weckso ecological center. For this purpose, 16 samplings were carried out between the months of May and August 2024, recording a total of 128 individuals distributed among the microenvironments: soil bromeliads, epiphytic bromeliads, bamboo stumps, and tree cracks. The canonical correspondence between the abundance of herpetofauna and climate change factors (temperature and precipitation volume) in the microenvironments demonstrated significant and inverse associations, whereas the ambient temperature increases, and precipitation decreases, amphibians and reptiles use humid microenvironments and when the rains begin, they are distributed to other environments. This was also confirmed by the analysis of the sample coverages of the online iNEXT program, obtaining quite complete coverages, for 93.9% in ground bromeliads; 82.8% in epiphytic bromeliads and 82.1% in bamboo stumps, just at the time of highest temperature and low rainfall. The species O. pumilio and D. auratus are vulnerable species by national law in this study and were the most associated and abundant in the microenvironments (phytotelmata).
