We seek to understand the possible factors that are driving rapid extinctions of amphibians throughout California. We propose to study the hydric and thermal elements of various amphibian habitats in order to observe their connection to amphibian extinctions. We have chosen paired extinct and persistent sites for all amphibian species of interest so that we may compare the environmental properties of each. We will deploy Agar models that are molded to the shape of Bufonidae, Pleobatidae, Rhyacotritonidae, Ranidae, and a general ellipsoid in order to accurately simulate the water-loss rates and internal body temperature of the respective amphibian. We will insert temperature probes into the agar models that are connected to HOBO data loggers that will record the internal temperature of the models throughout the day. Models will be deployed in several different conditions (Wet/Dry, Sun/Shade, Day/Night, Extinct/Extant) to determine the relative effect of each on water-loss and operative temperature. The data collected from these models will be used to construct a mathematical model that can be used to predict current and future extinctions of amphibians.
