Death From Drought In Tropical Forests Is Triggered By Hydraulics Not Carbon Starvation
(NATURE PUBLISHING GROUPLONDON, 2015)
Leaf-litter production in human-modified Amazonian forests following the El Niño-mediated drought and fires of 2015–2016
(2021-09-15)
Leaf-litter production is an essential part of the carbon cycle of tropical forests. In the Amazon, it is influenced by climate, presenting high levels during the driest months of the year. However, it is less established ...
Richness, diversity patterns, and taxonomic notes of amphibians from the Tocantins state
(Revista Biota Neotropica, 2020-01-01)
Herein, we provide the first comprehensive amphibian checklist for the State of Tocantins, North of Brazil, based on field sampling, literature data, and specimens deposited in zoological collections. We performed field ...
The impact of smoke from forest fires on the spectral dispersion of cloud droplet size distributions in the Amazonian region
(IOP PUBLISHING LTD, 2009)
In this paper, the main microphysical characteristics of clouds developing in polluted and clean conditions in the biomass-burning season of the Amazon region are examined, with special attention to the spectral dispersion ...
Behavioural and seminal characteristics of Santa Ines rams subjected to successive semen collections in the Amazonian region
(Pagepress Publ, 2012-01-01)
The objective of this study was to evaluate the reproductive performance of Santa Ines rams subjected to successive semen collections in an Amazonian climate. Four rams were subjected to successive ejaculations during a ...
Intercomparison of integrated water vapor estimates from multisensors in the amazonian region
(Amer Meteorological Soc, 2007-11-01)
Water vapor is an atmospheric component of major interest in atmospheric science because it affects the energy budget and plays a key role in several atmospheric processes. The Amazonian region is one of the most humid on ...
Drought sensitivity of Amazonian carbon balance revealed by atmospheric measurements
(MacmillanAmsterdam, 2014)
Feedbacks between land carbon pools and climate provide one of the
largest sources of uncertainty in our predictions of global climate1,2.
Estimates of the sensitivity of the terrestrial carbon budget to climate
anomalies ...
Impacts of Climate Change and the End of Deforestation on Land Use in the Brazilian Legal Amazon
(Amer Geophysical Union, 2011-05-01)
Climate change scenarios vary considerably over the Amazon region, with an extreme scenario projecting a dangerous (from the human perspective) increase of 3.8 degrees C in temperature and 30% reduction in precipitation ...
Solar energy budgets in central Amazonian ecosystems: a comparison between natural forest and bare soil areas
(1993-07-01)
In order to estimate the deforestation consequences on the actual solar energy budget of the Central Amazon Region, two ecosystems of different characteristics were compared. The present conditions of the region were ...
A palaeobiogeographic model for biotic diversification within Amazonia over the past three million years
(ROYAL SOCLONDON, 2012)
Many hypotheses have been proposed to explain high species diversity in Amazonia, but few generalizations have emerged. In part, this has arisen from the scarcity of rigorous tests for mechanisms promoting speciation, and ...
