Root niche separation can explain avoidance of seasonal drought stress and vulnerability of overstory trees to extended drought in a mature Amazonian forest
(AMER GEOPHYSICAL UNIONWASHINGTON, 2012)
Large areas of Amazonian evergreen forest experience seasonal droughts extending for three or more months, yet show maximum rates of photosynthesis and evapotranspiration during dry intervals. This apparent resilience is ...
Sustainability of renewable energy projects in the amazonian region
(Springer, Cham, 2018)
The Amazon is a fragile ecosystem with high biodiversity. However, urbanization of the region is creating pressure to provide electricity to its scattered population. Since 2010, Ecuador has been promoting rural electrification ...
Understorey fire propagation and tree mortality on adjacent areas to an Amazonian deforestation fire
(CSIRO Publishing, 2010-01-01)
Fire characteristics in tropical ecosystems are poorly documented quantitatively in the literature. This paper describes an understorey fire propagating across the edges of a biomass burn of a cleared primary forest. The ...

(CSIRO Publishing, 2010-01-01)
Fire characteristics in tropical ecosystems are poorly documented quantitatively in the literature. This paper describes an understorey fire propagating across the edges of a biomass burn of a cleared primary forest. The ...
Study on Mercury Methylation in the Amazonian Rivers in Flooded Areas for Hydroelectric Use
(2019-09-01)
This study aimed to estimate in laboratory the temporal production of methylmercury during the filling of reservoirs of hydropower plants and to correlate it to the ecosystem of different locations in northern Brazil: Jirau ...
A Retrospective Survey of Rodent-borne Viruses in Rural Populations of Brazilian Amazon
(Sociedade Brasileira de Medicina Tropical, 2020)
Malaria vector species in amazonian Peru co-occur in larval habitats but have distinct larval microbial communities
(Public Library of Science, 2019)
In Amazonian Peru, the primary malaria vector, Nyssorhynchus darlingi (formerly Anopheles darlingi), is difficult to target using standard vector control methods because it mainly feeds and rests outdoors. Larval source ...
A 60-million-year Cenozoic history of western Amazonian ecosystems in Contamana, eastern Peru
(Elsevier Science, 2016-03)
We provide a synopsis of ~. 60 million years of life history in Neotropical lowlands, based on a comprehensive survey of the Cenozoic deposits along the Quebrada Cachiyacu near Contamana in Peruvian Amazonia. The 34 ...
Biogenic calcium phosphate transformation in soils over millennial time scales
(SPRINGER HEIDELBERG, 2009)
Changes in bioavailability of phosphorus (P) during pedogenesis and ecosystem development have been shown for geogenic calcium phosphate (Ca-P). However, very little is known about long-term changes of biogenic Ca-P in ...
Amazonian trees show increased edge effects due to Atlantic Ocean warming and northward displacement of the Intertropical Convergence Zone since 1980
(Elsevier, 2019-11)
Recent investigations indicate a warming of Atlantic Ocean surface waters since 1980, probably influenced by anthropic actions, inducing rainfall intensification mainly during the rainy season and slight reductions during ...
