Chytrid Fungus (Bd, Bsal)

Amphibians are declining worldwide. Chytrid fungus (Batrachochytrium dendrobatidis, Bd) was identified 15 years ago as one of the primary causes of death for many amphibians. However, the ecology and epidemiology of Bd is still being investigated.  A second type of chytrid fungus (Batrachochytrium salamandrivorans, Bsal) is emerging in Europe and affecting salamanders. 

USGS formed the Amphibian Research and Monitoring Initiative (ARMI) to lead a cooperative national effort that is monitoring amphibians and researching potential causes of decline, including disease.

USGS is proactively responding to the threat of Bsal:

Cooperative Research

Blackrock: Biological Hotspot and Hotbed of Collaboration — Fort Collins Science Center

Amphibian Disease — Northern Rocky Mountains Science Center

Disease — Amphibian Research and Monitoring (ARMI)

Advancing ARMI: In search of Chytrid Fungus

In this episode, we follow a group of students from the Jane Goodall Environmental Middle School on a class trip to Pintail Marsh at the Ankeny National Wildlife Refuge. There they join USGS ecologist Tara Chestnut to investigate and sample for the amphibian chytrid fungus. Join us, as we explore how research and wonder can bring greater light to this potentially fatal fungus, only in this episode of the USGS Oregon Science Podcast.

Fatal Frog Fungus

The potentially lethal fungal disease chytridiomycosis has been associated with declining amphibian populations around the globe. This rapidly emerging disease, and the chytrid fungus that causes it, have forced scientists to scramble to learn more. There are still plenty of mysteries about the origin and spread of the fungus. With today's episode we will shed some light on what we know and what we can expect for the future of amphibians. Join us as we interview USGS ecologists Mike Adams and Tara Chestnut, as well as USGS hydrologist Chauncey Anderson.
