Local Demographic Rates of Four Eleutherodactylus Frogs in Puerto Rico, 2017-2019 (ver. 1.1, January 2025) Local Demographic Rates of Four Eleutherodactylus Frogs in Puerto Rico, 2017-2019 (ver. 1.1, January 2025)
We estimated the effect of microhabitat and microclimatic factors on occupancy, abundance and reproduction of four species of Eleutherodactylus frogs (E. wightmanae, E. brittoni, E. antillensis, E. coqui). Data consist of presence-non/presence data (binary), and physical (abiotic) and habitat (biotic) covariates collected at each of 48 survey stations (2017) and 35 (2018) along two...
Physiological Analysis of Eleutherodactylus Specimens in West-Central Puerto Rico, 2021-2022 Physiological Analysis of Eleutherodactylus Specimens in West-Central Puerto Rico, 2021-2022
Amphibians are vulnerable to extinction owing, partly, to altered physiological processes induced by projected global warming and drying. Understanding the mechanisms behind their responses is essential to formulate adaptation strategies for their conservation. Puerto Rico harbors 15 endemic Eleutherodactylus frogs considered vulnerable to extinction due to poor vagility and sensitivity...
