Novel Chronic Anaplasmosis in Splenectomized Patient, Amazon Rainforest [PDF]

Emerging Infectious Diseases, 2022
We report a case of unusual human anaplasmosis in the Amazon rainforest of French Guiana. Molecular typing demonstrated that the pathogen is a novel Anaplasma species, distinct to all known species, and more genetically related to recently described ...

Amazon rainforest adjusts to long-term experimental drought. [PDF]

Nat Ecol Evol
Abstract Drought-induced mortality is expected to cause substantial biomass loss in the Amazon basin. However, rainforest responses to prolonged drought are largely unknown. Here, we demonstrate that an Amazonian rainforest plot subjected to more than two decades of large-scale experimental drought reached eco-hydrological stability.

Drought Sensitivity of the Amazon Rainforest [PDF]

Science, 2009
Amazon forests are a key but poorly understood component of the global carbon cycle. If, as anticipated, they dry this century, they might accelerate climate change through carbon losses and changed surface energy balances. We used records from multiple long-term monitoring plots across Amazonia to assess forest responses to the intense ...

Cryptogamic organisms are a substantial source and sink for volatile organic compounds in the Amazon region

Communications Earth & Environment, 2021
Cryptogamic organisms such as bryophytes and lichens contribute substantially to emissions of secondary organic aerosol precursors as well as to the uptake of atmospheric oxidation products over the Amazon rainforest, suggest measurements at a remote ...

Isoprene photochemistry over the Amazon rainforest [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance For isolated regions of the planet, organic peroxy radicals produced as intermediates of atmospheric photochemistry have been expected to follow HO 2 rather than NO pathways. Observational evidence, however, has been lacking.
