Although the boreal forest has been proposed to accommodate increasing amounts of CO2, the large-scale response of photosynthesis to widespread noxious gases...
Direct monitoring of air quality does not cover more than the last three decades in most industrialized countries. For that reason studies using growth-ring...
Little is known about how forests adjust their gas-exchange mode while atmospheric CO2 rises globally and air quality changes regionally. The present study...
The dynamics of a cliff-top dune system located at the foot of the Mackenzie Mountains was reconstructed by radiocarbon dating and tree ring analysis of forest...
A tree is as a natural archive of valuable environmental information that allows going back in time if its growth rings are precisely dated, and the indirect...
As anthropogenic nitrogen (N) emissions have been rising for decades, it is critical to develop natural archives that help understand how natural processes...
At 94 sites throughout the Gaspésie peninsula, Québec, tree growth patterns and variation in growth rate were examined to determine relationship of tree growth...
Although the environmental impacts of metal atmospheric emissions from point sources such as smelter have been extensively studied, very fewstudies have...
Current-year, 1-year-old, and 2-year-old needles were collected separately on 37 black spruce (Picea mariana Mill. B.S.P.) trees located on a heavy metal...
In this study, tree-ring concentrations and stable isotope ratios of nitrogen in red spruce trees growing near Québec City (Canada) were used as records of...
