By: Muths E; Grant E; May 14, 2015

The salamander chytrid fungus (Batrachochytrium salamandrivorans; Bsal) was described in 2014, when die-offs in fire salamander (Salamandra salamandra) populations were reported in Europe. Susceptibility to this pathogen varies, but lethality is indicated in the families Salamandridae and Plethodontidae and members of both families occur in the US. Based on this endemicity, the discontinuity of th(...more)
Content image. 2015 ARMI annual meeting

By: Muths E; December 10, 2014

This year the annual ARMI meeting was a no-host event held outside of Denver in early December. This short meeting focused on in-depth discussions about management questions, basic science, and cross-discipline, integrative research to address amphibian declines. Topics included disease, methodologies, web-site and data management advances, and outreach.(...more)

By: Chestnut T; November 03, 2014

The amphibian chytrid fungus is an aquatic fungus implicated as a contributor to amphibian declines worldwide. Most research has focused on the dynamics of the pathogen in its amphibian hosts, with little emphasis on the ecology of the fungus in the environment. Therefore, we investigated patterns of amphibian chytrid fungus occupancy and density in amphibian habitats using occupancy models, power(...more)

ARMI Mission Statement

In response to indications of worldwide declines in amphibian populations, the President and Congress directed Interior Department agencies to initiate a national program of amphibian monitoring, research, and conservation. There is an urgent need to determine the scope and severity of the problem and to investigate causes. The U.S. Geological Survey is uniquely qualified to coordinate and lead a cooperative national effort because its scientists have been in the forefront of studying amphibian populations and life history traits, measuring and monitoring environmental characteristics, and conducting research into potential causes of decline. As a result, the Agency formed the National Amphibian Research and Monitoring Initiative (ARMI).

ARMI Goals and Objectives

  • » Provide information to natural resource managers on the status and trends of amphibians
  • » Relate status and trends to management options at the scale of management units.
  • » Identify causes of declines.
  • » Provide essential scientific information to support effective management actions to arrest or reverse declines.
