Extinction most likely for rare trees in the Amazon rainforest

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science.

The drivers of tropical deforestation are changing, say scientists

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

A shift from poverty-driven to industry-driven deforestation threatens the world's tropical forests but offers new opportunities for conservation, according to an article coauthored by William Laurance of the Smithsonian Tropical Research Institute in Panama. "New Strategies for Conserving Tropical Forests" will be featured in the September issue of the leading journal Trends in Ecology & Evolution.

A new species of predatory bagworm from Panama's tropical forest

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

University of Panama and Smithsonian researchers report the discovery of a new bagworm moth species, in the Annals of the Entomology Society of America. Unlike nearly all other bagworms, Perisceptis carnivora have predatory larvae. Strangest of all, according to Annette Aiello, staff scientist at the Smithsonian Tropical Research Institute, the adult moths wrap their eggs individually in beautiful cases fashioned from golden abdominal hairs called setae, a behavior unique among insects.

Insect warning colors aid cancer and tropical disease drug discovery

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama. Such clues could speed drug discovery and provide insight into the ecological relationships between tropical-forest plants and insects that feed on them.

First electrophysical recording of sleep in a wild animal

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

In the first experiment to record the electrophysiology of sleep in a wild animal, three-toed sloths carrying miniature electroencephalogram recorders slept 9.63 hours per day -- 6 hours less than captive sloths did, reports an international team of researchers working on the Smithsonian Tropical Research Institute's Barro Colorado Island in Panama.
