Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 1, Page 49-69, January 2023., 2023
Abstract Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser ...

Local hydrological conditions influence tree diversity and composition across the Amazon basin

open access: yesEcography, Volume 2022, Issue 11, November 2022., 2022
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well ...

Methylation of HPV16 and EPB41L3 in oral gargles and the detection of early and late oropharyngeal cancer

open access: yesCancer Medicine, Volume 11, Issue 20, Page 3735-3742, October 2022., 2022
We have expanded our previous study with priority in increasing early OPC case sample size to specifically test the performance of HPV16/EPB41L3 methylation as a biomarker for early OPC detection. This study, like the prior study, found HPV16/EPB41L3 methylation as a marker for OPC.

Active surveillance and early detection of community transmission of SARS‐CoV‐2 Mu variant (B.1.621) in the Brazilian Amazon

open access: yesJournal of Medical Virology, Volume 94, Issue 7, Page 3410-3415, July 2022., 2022
Abstract Through active surveillance and contact tracing from outpatients, we aimed to identify and characterize SARS‐CoV‐2 variants circulating in Porto Velho‐Rondônia, a city in the Brazilian Amazon. As part of a prospective cohort, we gathered information from 2,506 individuals among COVID‐19 patients and household contacts.
