Reconstructing Soil Recovery from Acid Rain in Beech (<i>Fagus sylvatica</i>) Stands of the Vienna Woods as Indicated by Removal of Stemflow and Dendrochemistry. [PDF]
Water Air Soil Pollut, 2019 Our goal was to reconstruct soil recovery from Acid Rain based upon removal of stemflow at beech (Fagus sylvatica) stands of known historic and recent soil status. Fourteen beech stands in the Vienna Woods were selected in 1984 and again in 2012 to study changes in soil and foliar chemistry over time.

Comparison between δ13C of α-cellulose and bulk wood in the mangrove tree Rhizophora mucronata: Implications for dendrochemistry [PDF]
Chemical Geology, 2005 Stable carbon isotope analysis of tree rings has become a widely used proxy in environmental and palaeoclimatological studies. In those studies, a-cellulose has often been the preferred material because of its singular composition and its immobility in wood.

Química Nova, 2009 Dendrochemistry is based on the determination of elements retained in tree rings, which can be useful to characterize environmental occurrences. This work shows elemental mappings obtained by EDXRF of the cross section of a tree stem.

Frontiers in Environmental ScienceIntroductionThe primary source of anthropogenic atmospheric mercury (Hg) emissions globally is artisanal and small-scale gold mining (ASGM). Estimates of Hg emissions from ASGM are poorly constrained due to a lack of monitoring data and the informal ...

Tropical dendrochemistry: A novel approach to estimate age and growth from ringless trees
Geophysical Research Letters, 2006 Although tropical forests play an active role in the global carbon cycle and climate, their growth history remains poorly characterized compared to other ecosystems on the planet. Trees are prime candidates for the extraction of paleoclimate archives as they can be probed sub‐annually, are widely distributed and can live for over 1400 years [Chambers ...

Methodology for Development of a 600-Year Tree-Ring Multi-Element Record for Larch from the Taymir Peninsula, Russia [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2013 We developed a long (600-year) dataset for the concentrations of 26 elements in tree rings of larch from the Taymir Peninsula, the northernmost region in the world (ca. 72°N) where trees grow. Tree rings corresponding to the time period from 1300 to 1900
