We determined their critical thermal maximum (CTMax) of four species of Eleutherodactylus frogs (E. wightmanae, E. brittoni, E. antillensis, E. coqui) 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).

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 to environmental variability. Herein are reported the effects of four temperature treatments (15, 20, 25, and 30 degrees Centigrade) on metabolic rates associated with specific dynamic action (SDA) and standard metabolic rates (SMR) of four representative species of Eleutherodactylus employing a respirometer. All species in either...

This dataset represents the extent of urbanization (for the year indicated) predicted by the model SLEUTH, developed by Dr. Keith C. Clarke, at the University of California, Santa Barbara, Department of Geography and modified by David I. Donato of the United States Geological Survey (USGS) Eastern Geographic Science Center (EGSC). Further model modification and implementation was performed at the Biodiversity and Spatial Information Center at North Carolina State University. Purpose: Urban growth probability extents throughout the 21st century for the Southeast Regional Assessment Project, which encompasses the states of Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee...

Project Objective: To provide science support, specifically conservation decision modeling expertise, to the SALCC team developing the regional conservation “blueprint.”Methods: A postdoctoral research associate (postdoc) will be hired to collaborate with the SALCC as they develop first a prototype Blueprint Version 1.0 and then update to Version 1.1. The postdoc’s project is envisioned to encompass three primary stages:Orientation and Version 1.0 Development: While SALCC leads the development of Version 1.0, the postdoc will attend the Blueprint workshops, contribute ideas and alternative design options, assist with the production of Blueprint Version 1.0. In addition to becoming oriented to the project and the...

The purpose of this project is to support the development and refinement of the Conservation Blueprint (v 2.0) by:1) Supporting the sharing and creation of geospatial data related to the Blueprint through South Atlantic Conservation Planning Atlas (CPA) maintenance and creation of Service Definition files to upload; modify symbology in ArcMap; copying and updating metadata; loading data onto the Landscape Conservation Map and linking it to the CPA; monitoring the data site to check forbroken links; responding to questions about the CPA; locating data and organizing metadata by receiving and reviewing data from project leaders and update metadata; and perfom1ing basicGIS analyses including rerunning ArcGIS models...
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 altitudinal gradients in west-central Puerto Rico.

Translocating individuals of Eleutherodactylus frogs to alternative, suitable habitat is an adaptation strategy designed to minimize the impact of projected warming and drying in Puerto Rico. The action increases species persistence by increasing spatial redundancy, but it could also be used to supplement extant populations. We released 34 Eleutherodactylus coqui to determine initial, post-release survival under two treatments – non-translocated (N = 14), and translocated (N=20) to a different location 0.8 km away, but sharing similar habitat and environmental conditions. We defined “initial” as the first 17 days post-release, a period where we hypothesized that translocated individuals would have lower survival...

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).
