I am currently in Bolivia to study the critically endangered frog Psychrophrynella illimani in the high Andes. I will post some more information about this work in a separate blog post. Below are some pictures of several frogs we encountered so far. The species numbers at these high altitudes are not very impressive, as only few species can cope with the harsh conditions in this spectacular environment.
