President Evo Morales said Tuesday that he was rescinding a contract awarded to the Brazilian company OAS to build a road through the Amazon, casting further doubt on a project that set off fierce
This report introduces the National Adaptive Capacity (NAC) framework, a tool to help governments bring institutional capacity development into their adaptation planning processes. The NAC framework enables its users to systematically assess institutional strengths and weaknesses that may help or hinder adaptation.
Eight South American countries pledged Tuesday to boost cooperation to protect one of the planet’s largest natural reserves from deforestation and illegal trafficking in timber and minerals.
A strong 6.6-magnitude earthquake rattled Bolivia on Tuesday and was also felt in Peru and Chile, but the epicenter was deep underground and there were no immediate reports of damage or casualties.
The US Geographical Survey said the quake's epicenter was 345 miles (556 kilometers) underground and located 37 miles south-southwest of Trinidad, the capital of Bolivia's northern Beni region.
Tropical South America is rich in different groups of pollinators, but the biotic and abiotic factors determining the geographical distribution of their species richness are poorly understood. We analyzed the species richness of three groups of pollinators (bees and wasps, butterflies, hummingbirds) in six tropical forests in the Bolivian lowlands along a gradient of climatic seasonality and precipitation ranging from 410 mm to 6250 mm.
Biological invasion and climate change pose challenges to biodiversity conservation in the 21st century. Invasive species modify ecosystem structure and functioning and climatic changes are likely to produce invasive species' range shifts pushing some populations into protected areas. The American Bullfrog (Lithobates catesbeianus) is one of the hundred worst invasive species in the world. Native from the southeast of USA, it has colonized more than 75% of South America where it has been reported as a highly effective predator, competitor and vector of amphibian diseases.
The causes and timing of tropical glacier fluctuations during the Holocene epoch (10,000 years ago to present) are poorly understood. Yet constraining their sensitivity to changes in climate is important, as these glaciers are both sensitive indicators of climate change and serve as water reservoirs for highland regions.
