 I am studying the diversity, biogeography, evolution and physiology of terrestrial breeding frogs to better understand why species live at different elevations and how they respond to environmental change in the Andes-Amazon region of Peru. One of the main goals of the work we have been doing at Manu National Park is to survey known and previously unexplored areas in search of species, both amphibians and reptiles, determining their habitat preferences and collect specimens and tissues for genetic analysis. Manu Poison Frog is a species that was described from the National Park, originally found in the lowlands, and then live in the lowlands and also in the mountain forests, and their bright coloration is supposed to advertise its toxicity to predators. Manu Frog is a species that lives in the lowland rainforest, and they usually are found on the leaf leader. They create this small cavity where they are sitting. Sometimes they are sitting for days. They are called seed and weight predators because they are just sitting waiting for something to walk by, and they have a very large mouth, like the mouth is almost half of the size of the head, or almost half of the body, and they can eat basically anything that fits into their mouth, like other frogs, spiders, lots of insects, and once in a while other vertebrates. The Glass Frog is one of seven species of Glass Frogs living in Manu National Park, and this type of, this group of frogs, they all breed along streams. They usually lay the eggs on top of leaves, or in some species underneath the leaves that are hanging on top of streams, and usually one of the parents is protecting the eggs, and when the eggs hatch, the tadpoles drop into the water, into the streams, and they complete their tadpole development, or larval development in the water, so they are usually strongly associated with streams. This frog is a type of leaf frog. There are six species of leaf frogs living in the lowlands of Manu National Park and its buffer zone, and all of these are nocturnally active, so they are active only at night, likewise, like the Glass Frogs. This is a stream lizard, and stream lizards are, as their name says, living along streams, and this is a new species that is currently being described, it's only found in Manu National Park, and one interesting thing is that they are adapted to living in these relatively cool environments, and once in a while they get into the streams when they escape from any threat and they can remain under water for a few minutes.
