Fire may prevent future Amazon forest recovery after large-scale deforestation

open access: yesCommunications Earth & Environment, 2023
The Amazon forest is regarded as a tipping element of the Earth system, susceptible to a regime change from tropical forest to savanna and grassland due to anthropogenic land use and climate change.

River dataset as a potential fluvial transportation network for healthcare access in the Amazon region

open access: yesScientific Data, 2023
Remote areas, such as the Amazon Forest, face unique geographical challenges of transportation-based access to health services. As transportation to healthcare in most of the Amazon Forest is only possible by rivers routes, any travel time and travel ...

Higher absorbed solar radiation partly offset the negative effects of water stress on the photosynthesis of Amazon forests during the 2015 drought [PDF]

open access: yes, 2018
Amazon forests play an important role in the global carbon cycle and Earth\u27s climate. The vulnerability of Amazon forests to drought remains highly controversial.

The Amazon Forest [PDF]

open access: yes, 1991
Most of the Amazon Basin is covered with dense tropical rain forest comprised of many different species of trees and shrubs, often hundreds of different species per square kilometer. These are by far the world’s most extensive and rich virgin forests. The forests are often less dense and even patchy on the highland fringes of the basin.

Diazotrophs Show Signs of Restoration in Amazon Rain Forest Soils with Ecosystem Rehabilitation. [PDF]

open access: yes, 2020
Biological nitrogen fixation can be an important source of nitrogen in tropical forests that serve as a major CO2 sink. Extensive deforestation of the Amazon is known to influence microbial communities and the biogeochemical cycles they mediate. However,

Amazon tree dominance across forest strata [PDF]

open access: yesNature Ecology & Evolution, 2021
The forests of Amazonia are among the most biodiverse plant communities on Earth. Given the immediate threats posed by climate and land-use change, an improved understanding of how this extraordinary biodiversity is spatially organized is urgently required to develop effective conservation strategies.

Forest regeneration pathways in contrasting deforestation patterns of Amazonia

open access: yesFrontiers in Environmental Science, 2023
Secondary vegetation is increasingly recognized as a key element for biodiversity conservation and carbon stocks in human-modified landscapes. Contrasting deforestation patterns should lead to distinct patterns of forest regeneration, but this ...

New generation geostationary satellite observations support seasonality in greenness of the Amazon evergreen forests

open access: yesNature Communications, 2021
Cloud cover and scarcity of ground-based validation hinder remote sensing of forest dynamics in the Amazon basin. Here, the authors analyse imagery from a high-frequency geostationary satellite sensor to study monthly NDVI patterns in the Amazon forest ...

The role of vicariance and dispersal on the temporal range dynamics of forest vipers in the Neotropical region.

open access: yesPLoS ONE, 2021
The emergence of the diagonal of open/dry vegetations, including Chaco, Cerrado and Caatinga, is suggested to have acted as a dispersal barrier for terrestrial organisms by fragmenting a single large forest that existed in South America into the present ...

Future of oil and gas development in the western Amazon [PDF]

open access: yes, 2014
The western Amazon is one of the world's last high-biodiversity wilderness areas, characterized by extraordinary species richness and large tracts of roadless humid tropical forest.
