A new guide to the orchid bees of tropical America is now available. Co-authored by David Roubik, Staff Scientist at the Smithsonian Tropical Research Institute in Panama, and Paul E. Hanson; published by Costa Rica's National Biodiversity Institute (INBio), this bilingual field guide provides a "comprehensive review of orchid bee studies aimed at both biologists and those bold enough approach rainforest bees out of curiosity."

A research team of U.S. and Brazilian scientists has shown that rainforests in central Amazonia are experiencing striking changes in dynamics and species composition. Although the cause of these changes are believed to be completely undisturbed, old-growth forests is uncertain, a leading explanation is that they are being driven by rising levels of carbon dioxide in the atmosphere.

Panama's International Cooperative Biodiversity Group (ICBG) announces the development of a new test for identification of antimalarial compounds with wide applicability in the developing world. The assay for plant-derived compounds also can be used to detect anti-plasmodial compounds from synthetic or natural sources. Initial results of the research are published in the American Journal of Tropical Medicine and Hygiene under the title "A Novel DNA-Based Microfluorometric Method to Evaluate Antimalarial Drug Activity".

Insect feces and leaf litter in the rainforest may provide important clues to better understanding global climate change, according to a group of scientists conducting research in the Panamanian rainforest on a JASON Project expedition.
