Early- and Latewood vs. Stem Asymmetry: Which Is More Important for Dendrochemistry in Scots Pine?
ForestsFor dendrochemical research, it may be important to be aware of the effects of stem asymmetry and the intra-ring structure because these may introduce unwanted dispersion in the results. In dendrochemical studies, separate analysis of the elemental content of early- and latewood is rare.

Change in the dendrochemistry of sacred fir close to Mexico City over the past 100 years
Environmental Pollution, 1999The chemistry of the tree-rings of sacred fir (Abies religiosa) growing in the high elevation forest park, Desierto de los Leones, close to Mexico City was measured in 5 year increments dating back to 1897. Surface soil beneath sampled trees had elevated concentrations of trace metals, especially Pb, Cd and Zn, compared with a reference site at San ...

Dendrochronologia, 2010
Abstract The maple-dominated forest of eastern Canada and northeastern United States has experienced forest decline that can be linked to changes in soil fertility and soil acidification. In this study, we used a new dendrochemical approach to trace back changes in nutrients (Ca, K, Mg, and Mn) and Al availability.

Biogeochemistry, 2014
Tree rings are a useful long term monitor of climate change indicators and certain atmospheric constituents. Since we have no long-term historical record of air mercury (Hg) concentrations, and previous research demonstrates atmospheric uptake of Hg into vegetative biomass, we hypothesized that tree rings would be a useful archive for monitoring ...

Drilling at the c. 750 m deep Halliday Lake prospect in the Athabasca Basin has identified features favourable for unconformity-related U mineralization such as sandstone enrichments in pathfinder elements, graphitic metapelite gneiss, sandstone and basement hosted faulting, hydrothermal alteration and sub-economic ...

Plant and Soil, 2004
Ten pairs of secondary pure spruce (Picea abies) and adjacent mixed spruce-beech (Fagus sylvatica) stands on comparable sites were selected on two different bedrocks for soil formation (Flysch: nutrient rich and high soil pH; Molasse: poor nutrient supply and acidic) to study how an admixture of beech to spruce stands affects nutrient cycling and ...

Through they Eyes of a Tree: Monitoring Environmental Change Using Stable Isotope Dendrochemistry
2013Stable isotope dendrochemistry of needles, twigs, and tree rings were used to identify the impacts of a changing global atmosphere in two separate environments with different anthropogenic loads: the boreal forest surrounding the Athabasca Oil Sands region (AOSR), Alberta, Canada, subject to a large point source of anthropogenic emissions, and the ...

A dendrochronological and dendrochemical study was undertaken near the village of Kuujjuaq, northern Quebec. Changes in climate, radial growth and mineral nutrition of trees, as well as the contamination in Mn and Zn of tamarack and black spruce forests of the region during the last forty years were investigated.
