Frog and reptiles in Costa Rica

As I reported, we were near La Selva Biological Station, Costa Rica, on 16 March 2014. There was a strawberry poison dart frog.

A green basilisk.

Crested guan in a tree.

Great curassow in a tree nearby.

While on the ground, there is busy traffic on leaf-cutter ant highways. In one direction, ants bring back pieces of leaf to their colony. In the opposite direction are the ants which yet have to get a piece of leaf.

On a piece of leaf along the rainforest path, a ground anole lizard.

A Central American whiptail lizard later.

Mantled howler monkeys call.

A black-throated trogon on a branch.

A dusky-faced tanager.

We went back to the entrance. Stay tuned!

Strawberry poison frogs live in Costa Rican forests that are being cut down for farmland. The deforested pastures are hotter and sunnier, so scientists wanted to see if the frogs had adapted to withstand the heat. They learned that the frogs from pastures had adapted to seek out warmer temperatures than frogs from forests. The maximum temperature they can stand didn’t change, though — so if global temperatures rise too much, the frogs are in trouble: here.
