By granting rights to Nature, Bolivia and Ecuador have subverted conventional wisdom on the use of natural resources. (Editorial)

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.

Harmony marked the end of the climate summit in Canc

When the dust settles after the Cancun climate change conference of the United Nations, a careful analysis will find that the adoption of the “Cancun Agreements” may have given the multilateral climate system a shot in the arm, but that the meeting also failed to save the planet from climate change and helped pass the burden of climate mitigation onto developing countries.

The global powers that be fiddle even as Cancun takes the mitigation of climate change backwards. (Editorial)
