Micro-X-ray fluorescence (μ-XRF) spectroscopy has been used for dendrochemistry as a high spatial resolution, multi-elemental and non-destructive technique. Furthermore, micro-X-ray absorption near edge structure (μ-XANES) potential application in environmental studies by adding speciation information under in-situ conditions. Both, μ-XRF μ-XANES, techniques were to assess the inter-ring intra-ring chemical content variations of Avicennia schaueria mangrove tree from Southeastern Brazil. Ca,...
Abstract Background Treeline ecotones of Mediterranean ecoregions have been affected by the increasing intensity and severity droughts. Even though effect droughts on forest dynamics has widely documented, knowledge is relatively scarce how extreme climate episodes affect hydraulic structure and, therefore, physiology woody plants. The Andes experienced an uninterrupted period drought since 2010, including extremely dry year in 2019 with approximately 80% rainfall deficit. Here, we...
To ensure unbiased tree-ring radiocarbon (14C) results, traditional pretreatments carefully isolate wood cellulose from extractives using organic solvents, among other chemicals. The addition of solvents is laborious, time-consuming, and can increase the risk carbon contamination. Tropical woods show a high diversity in wood-anatomical extractive composition, but necessity organic-solvent extraction for 14C dating these diverse remains untested. We applied chemical treatment that excludes...
Tree-ring width chronologies of cedro (Cedrela fissilis Vell.) (1875 to 2018), jatobá (Hymenaea courbaril L.) (1840 2018) and roxinho Peltogyne paniculata Benth.) (1910 were developed by dendrochronological techniques in the southern Amazon Basin. Acceptable statistics for tree-ring obtained, annual calendar dates assigned. Due lack long-term use paleoclimate reconstructions degraded forest areas, dating was validated 14C analysis. Tree-rings selected analysis corresponded 1957, 1958, 1962,...
Context: Gold mining is the most destructive activity in natural forests of Madre de Dios region southeastern Peruvian Amazon. Understanding regeneration process these degraded areas necessary to develop forest restoration projects such conditions. Aims: We aimed evaluate recovery and identify successional structure patterns vegetation governing over time. Methods: Structure, composition, richness, diversity, status were evaluated abandoned artisanal gold mine Dios, Peru. Vegetation data...
Abstract Background The increase in the frequency and intensity of droughts is pointed out as one main factors altering biogeochemical cycles Amazon basin. An eco-nutritional approach using X-ray fluorescence micro-analysis (µXRF) proposed to verify long- short-term effects on growth xylem nutrient concentrations Cedrela fissilis Vell. Methods Fourteen radii were selected from a tree-ring width chronology X-rayed by Itrax Multiscanner. Profiles ring width, wood density, aluminum (Al),...
Abstract Background Dehydration of plant tissues caused by water stress affects the dynamics lateral cambium, rate cell division and differentiation in lumen size, wall thickness chemical properties. Based on evidence that ongoing climate change projects longer more intense conditions, forest decline are predicted to be affected increases drought intensity frequency. To verify interaction these phenomena, we described modifications anatomy mineral contents annual growth rings Araucaria...
Abstract Potentially toxic elements (PTEs) from mining industries pollute the surrounding environment and threaten health of communities. Worldwide, exotic indigenous trees are being recommended for green belts to trap dust thereby limit dispersion PTEs. This study compares potential ( Eucalyptus grandis E. camaldulensis ) native Brachystegia longifolia tree species in Zambia accumulate PTEs evaluate their ability biomonitor heavy metal pollution. Tree bark leaf samples were collected 10 per...
