Abstract

For well over a decade, scientists have been trying to pinpoint the environmental cause for declining populations of amphibians in many habitats across the globe. Here, scientists and resource management professionals from a range of disciplines discuss standardized amphibian toxicity tests and methods to characterize adverse effects from chemical stressors; the current state of technical tools available to scientists to asses amphibian populations exposed to various environmental stressors; and a process that brings interdisciplinary technical and management tools to analyzing the cause, and establishes a multiple stressor risk assessment mind set.
