A Frog that Few Have Laid Eyes On

A Frog that Few Have Laid Eyes On

Here is a frog that few have ever laid eyes on – Legler’s Tree Frog (Ptychohyla legleri). This is one of the target species of RTPI Director Twan Leenders’ recent trip to the mountains of Costa Rica where he joined RTPI Research Associate Alex Shepack in surveys of imperiled amphibian populations. Legler’s Tree Frog is an endangered species with a very small and highly fragmented distribution range. It is the only species in its genus in lower Central America; its nearest relatives are found in northern Nicaragua and countries north of there. This recently metamorphed individual was found...

Spider Silk – the Next Sustainable Resource?

Spider silk is the world’s strongest natural fiber known – it is incredibly durable but also extremely lightweight and flexible. One strand of spider silk is one-tenth the thickness of a human hair, and its flexibility resembles that of thread. These qualities are unmatched by other fibers, such as cotton or nylon, giving it a wide variety of industrial applications. The value of spider silk is increased by the fact that it can be a renewable resource. RTPI conservation staff works with the Forman School during research expeditions in Costa Rica to explore the potential to “farm”...

Glass Frogs

Researchers from the Roger Tory Peterson Institute of Natural History (RTPI) have been monitoring Glass frogs and other amphibian species in Central America for more than two decades – not only to keep these frogs from extinction, but also to learn how some populations have been able to survive catastrophic declines due to the parasitic Chytrid fungus. Hopefully this information will help us as we try to find ways to help other endangered species as well. Glass frogs owe their common name to their transparent undersides which, in some species, allow one to see their internal organs. Note...

Bicolored Antbird

Bicolored Antbird

Here’s a catch made during my recent research trip to Costa Rica. Not a neotropical migrant this time, but a local resident species. This unusual-looking fellow is a Bicolored Antbird (Gymnopithys leucaspis), one of several so-called “ant-birds” that are usually found only in the vicinity of army ant swarms. All day long these birds follow the ants -at a safe distance- and expertly capture insects that are flushed, but not caught, by the invading...

RTPI provides innovative programs that bring nature back into people’s lives. RTPI researchers work with school and college students to give them a chance to study natural history first-hand, and open their eyes and minds to the workings of the natural world. Whether in our own backyard, or in a remote corner of Costa Rica, RTPI works to increase understanding of the natural connections between species, habitats, and people that are critical to effective conservation. Learn more in this outstanding video created by Nicholas Gunner of...
