Collazo, J.A, and Rivera-Burgos, A.C., 2022, Local demographic rates and Critical Thermal Maximum (CTMax) values of four Eleutherodactylus frogs in Puerto Rico, 2021-2022: U.S. Geological Survey data release, https://doi.org/10.5066/P9VN4DFK.
Summary
We determined the critical thermal maximum (CTMax) of six species of Eleutherodactylus frogs (Eleutherodactylus antillensis, Eleutherodactylus brittoni, Eleutherodactylus cochranae, Eleutherodactylus coqui, Eleutherodactylus juanariveroi, Eleutherodactylus wightmanae) to understand their response to warming temperatures. Data consist of capture history, body condition, and temperature at which the frog exhibited spasms and erratic behavior, which may impair predator avoidance. Our results underscored the potential vulnerability of Eleutherodactylus species exhibiting lower CTMax to the forecasted warming of tropical zones (e.g., E. wightmanae, E. brittoni).

Purpose
To understand the limits of six representative Eleutherodactylus species under changing climatic conditions. Specifically, establish their critical thermal limits (CTMax). The information will be used to test predictions about site quality, and validate the suitability of potential climate refuges. The information will be used by the U.S. Fish and Wildlife Service and the P.R. Department of Natural and Environmental Resources to implement two adaptation strategies, namely, managed translocations and identify climate refuges to help recover listed species and prevent the listing of species “at risk” from becoming threatened or endangered.
