Researchers challenge a recent study's estimate of greenhouse gas emissions from tropical deforestation, citing seven serious errors that lead to a major underestimate. The Achard study failed to account for drier forests, biomass, and the effects of methane and nitrous oxide.
The Amazon forest, a significant carbon sink, may be slowing global climate change. A new monitoring team, RAINFOR, aims to study the impact of environmental changes on Amazonian forests. The project will analyze data from multiple sites across the basin to better understand productivity and dynamics.
The Association for Tropical Biology honors Ira Rubinoff's vision and perseverance in defining the direction of tropical biology research. His contributions include establishing Panama's Soberania National Park, Barro Colorado Nature Monument, and promoting forest conservation.
Advanced sensors and communication platforms can monitor complex tropical environments to track elusive animals and study their behavior. Technologies like automated telemetry systems, high-quality sound recordings, and radiotransmitters are being developed to aid conservation efforts in the Amazon basin.
Deforestation rates in Brazilian Amazonia averaged seven football fields per minute, with highway proximity being a significant predictor. Current policy initiatives to expand infrastructure networks will likely increase deforestation activity, particularly in south-easterly areas.
The U.S.-Peru debt-for-nature swap aims to conserve ten tropical rain forest areas covering over 27.5 million acres, home to rare biodiversity and threatened species. The agreement generates funds for local Peruvian conservation groups and provides critical income streams for front-line conservation efforts.
Researchers estimated that New Guinea's plant community is dominated by clusters of closely related plant species, which are fed upon by a greater number of insects. This discovery leads to revised estimates of total world species numbers, with the range being between 4.8 million and 6 million.
A new study estimates 3.7 to 5.9 million insects worldwide, down from Erwin's initial estimate of 30 million. The research suggests that specialist herbivores are rare, and genera rather than species are the preferred unit for biodiversity calculations.
Researchers have recalculated the amount of carbon dioxide released from tropical forests into global waterways, finding that it is triple the current estimate. The new total is comparable to a fifth of human activities' carbon dioxide emissions, challenging the notion that forests are carbon sponges.
Kingston's work led to a semi-synthetic process for creating Taxol, improving the efficiency of a potent anti-cancer drug. His research also contributed to saving vital tropical forests in South America by preserving traditional herbal remedies.
Researchers found a wide swath of the western Amazon has a forest with minimal species change over distances of over 1000 kilometers. In contrast, forests on the Isthmus of Panama exhibit high beta-diversity due to abrupt variation in rainfall across the Central American isthmus.
Researchers found that moderately intense disturbances contribute to high tree species diversity in tropical rain forests. The study challenges previous findings, which suggested no effect of disturbance on diversity, and instead supports the intermediate disturbance hypothesis. The presence of heliophilous trees indicates recent canop...
Rainforest fragments experience 'edge effects' that hinder seed germination, with seeds being three to seven times less likely to sprout than those in continuous forests. Inbreeding can further reduce reproduction rates, threatening the survival of populations in forest fragments.
A 20-year protocol developed by Dr. Charles Peters is applied to dozens of projects, combining exploitation with preservation of biodiversity and ecosystem functions. Local indigenous people in Asia, Africa, and Central/South America are empowered to manage their forests sustainably.
A study by Duke University researchers found that selectively logged Indonesian rainforests have comparable levels of tree species diversity to unlogged forests eight years later. The results suggest that these forests are more resilient than previously thought and may hold conservation potential.
Participants of a forest-biodiversity workshop suggest using logging as a tool to save tropical forests and their wildlife. By implementing basic techniques such as directional felling and minimizing logging roads, biodiversity can be conserved. The experts also emphasize the need to maintain suitable habitat within major forest types.
