Running into Rare Frogs…

With so much time in the field, we bump into all kinds of rare and infrequently seen amphibians.  Here are a few of the recent encounters…

In the Field Again

We have been busy looking at dozens of localities and testing for emergent infectious disease.  We wanted to show everyone some images from the field.

Some individual Darwin's Frogs (Rhinoderma darwinii) have a nice mix of greens with other colors.

It's always nice to see amphibians calling and breeding in the field.  This is the Four Eyed Frog (Pleurodema thaul) calling.

Skin swabs are the contemporary way that scientists test for amphibian chytrid fungus.  The process is relatively non-invasive.  A swab is rubbed on the skin of the amphibian a number of times, then sent to a lab for PCR testing.  The animal is released, unharmed.

Field trips are busy. Gear takes up much of the room in the field vehicles.

Often times, we use horses to trek into a remote forest patch.  We camp in these remote sites for several days while we survey the amphibians there.
