UnknownA "Dirty" Footprint: Macroinvertebrate diversity in Amazonian Anthropic Soils.
Amazonian rainforests, once thought to be pristine wilderness, are increasingly known to have been widely inhabited, modified, and managed prior to European arrival, by human populations with diverse cultural backgrounds. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Bas...

UnknownWest Nile Virus in the State of Ceara, Northeast Brazil.
In June 2019, a horse with neurological disorder was diagnosed with West Nile virus (WNV) in Boa Viagem, a municipality in the state of Ceará, northeast Brazil. A multi-institutional task force coordinated by the Brazilian Ministry of Health was deployed to the area for case investigation. A total o...

UnknownFamily imprint reveals basin-wide patterns of Amazon forest embolism resistance.
Amazon rainforests face intensifying water stress due to increases in vapour pressure deficit and changing hydrological regimes. Embolism resistance (Ψ50) is a critical metric of tree survival under drought conditions, it is defined as a plant's capacity to resist disruption of xylem wate...

TranscriptomicsTrancriptome analysis of peripheral leukocytes from SARS-CoV-2 infected patients and healthy uninfected individuals during the first wave of COVID-19 pandemic in Brazil
To evaluate the gene expression profiling of peripheral leukocytes in different outcomes of SARS-CoV-2 infections, whole blood samples were collected from individuals with positive SARS-CoV-2 nasopharyngeal swab by RT-PCR (54 patients) and healthy uninfected individuals (12 volunteers). Infected pat...

TranscriptomicsFunctional Networks Of Praziquantel-Induced Differentially Expressed Genes In Schistosoma mansoni And Synergy Of Omeprazole And Praziquantel In Vitro Against Adult Worms
Background: Treatment and morbidity control of schistosomiasis relies on a single drug, praziquantel. Therefore, there is a pressing need to explore the effects of PZQ on the parasites at the molecular level and to pursue alternative and/or or synergistic drugs against schistosomiasis. Methodology...

UnknownFast demographic traits promote high diversification rates of Amazonian trees.
The Amazon rain forest sustains the world's highest tree diversity, but it remains unclear why some clades of trees are hyperdiverse, whereas others are not. Using dated phylogenies, estimates of current species richness and trait and demographic data from a large network of forest plots, we show th...

UnknownBiased-corrected richness estimates for the Amazonian tree flora.
Amazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show th...

UnknownTree mode of death and mortality risk factors across Amazon forests.
The carbon sink capacity of tropical forests is substantially affected by tree mortality. However, the main drivers of tropical tree death remain largely unknown. Here we present a pan-Amazonian assessment of how and why trees die, analysing over 120,000 trees representing > 3800 species from 189 lo...

UnknownUnraveling Amazon tree community assembly using Maximum Information Entropy: a quantitative analysis of tropical forest ecology.
In a time of rapid global change, the question of what determines patterns in species abundance distribution remains a priority for understanding the complex dynamics of ecosystems. The constrained maximization of information entropy provides a framework for the understanding of such complex systems...

UnknownConsistent patterns of common species across tropical tree communities.
Trees structure the Earth's most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common s...
