Leaf deciduousness and flowering of woody caatinga species

open access: yesBiotemas, 2020
We determined the distribution (FDI), duration (FDU), and peak (FPE) of flowering in woody deciduous (DE) and evergreen (EV) species of the Caatinga with available data in the literature.

Can bulk-fill resin restorations be an alternative to resin-modified glass ionomer cement restorations in primary molars of toddlers? A randomized clinical trial protocol

open access: yesJournal of Oral Research, 2021
Background: The aim of this study was to elaborate a randomized clinical trial protocol to evaluate the effectiveness of class I restorations in resin-modified glass ionomer cement (RMGIC) and bulk-fill resin in primary molars with untreated early ...

Upscaling carbon fluxes from towers to the regional scale: Influence of parameter variability and land cover representation on regional flux estimates [PDF]

open access: yes, 2011
Quantifying the current carbon cycle of terrestrial ecosystems requires that we translate spatially sparse measurements into consistent, gridded flux estimates at the regional scale.

Mapping forests in monsoon Asia with ALOS PALSAR 50-m mosaic images and MODIS imagery in 2010. [PDF]

open access: yes, 2016
Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and quantify these effects. In this study, an algorithm

Decidualization resistance in the origin of preeclampsia [PDF]

open access: yesAmerican Journal of Obstetrics and Gynecology, 2022
Preeclampsia is a major obstetrical complication with short- and long-term life-threatening consequences for both mother and child. Shallow cytotrophoblast invasion through the uterine decidua into the spiral arteries is implicated in the pathogenesis of preeclampsia, although the cause of deficient arterial invasion remains unknown.

Remarkable Similarity in Timing of Absorptive Fine-Root Production Across 11 Diverse Temperate Tree Species in a Common Garden

open access: yesFrontiers in Plant Science, 2021
Long-term minirhizotron observations of absorptive fine roots provide insights into seasonal patterns of belowground root production and carbon dynamics. Our objective was to compare root dynamics over time across mature individuals of 11 temperate trees

Hormonal Orchestration of Bud Dormancy Cycle in Deciduous Woody Perennials

open access: yesFrontiers in Plant Science, 2019
Woody perennials enter seasonal dormancy to avoid unfavorable environmental conditions. Plant hormones are the critical mediators regulating this complex process, which is subject to the influence of many internal and external factors.

Daylength helps temperate deciduous trees to leaf‐out at the optimal time

open access: yesGlobal Change Biology, 2019
Global warming has led to substantially earlier spring leaf‐out in temperate‐zone deciduous trees. The interactive effects of temperature and daylength underlying this warming response remain unclear.
