Our team performed an amphibian survey at Oncol National Park, Los Rios, Chile.  One of the amphibians encountered was this mature adult male Alsodes norae.  When males are ready to breed, they develop the spines on their chest that can be seen in one of the images below.  Their forearms also become larger and more robust.  These things presumably allow males to hold onto females in the prereproductive embrace known as “amplexus.”

On an amphibian survey in south Chile (November 2014), with Dr. José Nuñez and his graduate students, we encountered a breeding aggregation of the Chilean Widemouth Frog (Calyptocephalella gayi).

We devoted a considerable amount of our field time last year to surveying streams for the Mehuín Green Frog, Insuetophrynus acarpicus.  This species has suffered from habitat loss and is widely considered one of the most endangered frog species.
