Nitrogen deposition and increased carbon accumulation in ombrotrophic peatlands in eastern Canada
[1] Recent and long-term accumulation rates of carbon (C), using Pband C-dating, were examined in 23 ombrotrophic peatlands in eastern Canada, where average 1990–1996 atmospheric wet nitrogen (N) deposition ranged from 0.3 to 0.8 g N m 2 yr . The average recent rate of C accumulation (RERCA) over the past 150 years was 73 ± 17 (SD) g C m 2 yr , ranging from 40 to 117 g C m 2 yr . The difference...
متن کاملLong-term change of polycyclic aromatic hydrocarbon deposition to peatlands of eastern Canada.
To date, studies about historic PAH (polycyclic aromatic hydrocarbons) deposition at a regional scale have rarely been published. To address this research gap, we sampled 17 ombrotrophic peatlands across eastern Canada. The peat cores from hollows were dated with 210Pb for the period of about 1850-2000 and analyzed fortheir PAH concentration, so PAH deposition could be reconstructed. Peat sampl...
متن کاملSnowblading injuries in Eastern Canada.
OBJECTIVES To evaluate injury patterns of snowbladers and compare them with those of skiers and snowboarders. To determine possible effects of helmet use in these sports on injury to the head and neck. METHODS This prospective case series observational study was conducted by collecting the injury reports from the ski patrol during the 1999-2000 season at Mont Tremblant ski resort, Quebec. All...
متن کاملPachybrachis (Coleoptera, Chrysomelidae, Cryptocephalinae) of Eastern Canada
Seventeen Pachybrachis species occurring in eastern Canada [Ontario (ON), Québec (QC), New Brunswick (NB), Nova Scotia (NS), and Prince Edward Island (PE)] are treated by the authors. Two new national records were discovered, both from southernmost Ontario: P. cephalicus Fall and P. luctuosus Suffrian. Four species were new provincial records: P. cephalicus (ON), P. luctuosus (ON, QC), P. obsol...
متن کاملControls on bacterial and archaeal community structure and greenhouse gas production in natural, mined, and restored Canadian peatlands
Northern peatlands are important global C reservoirs, largely because of their slow rates of microbial C mineralization. Particularly in sites that are heavily influenced by anthropogenic disturbances, there is scant information about microbial ecology and whether or not microbial community structure influences greenhouse gas production. This work characterized communities of bacteria and archa...
