We will be performing routine ERA maintenance starting 3PM Tuesday Feb 19 until 3PM Wednesday Feb 20. ERA searches and downloads will perform as usual, but the "Deposit" and "Edit" function will be suspended during the maintenance period. When the work is complete, we'll remove this notice. Thanks for your understanding!

Current uptake of 15N –labeled ammonium and nitrate in flooded and non-flooded black spruce and tamarack seedlings.Download
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....
Ecophysiological adaptations of black spruce (Picea mariana) and tamarack (Larix laricina) seedlings to flooding.Download
Black spruce and tamarack are the predominant tree species in boreal peatlands. The effects of flooding on morphological and physiological responses were investigated in greenhouse grown (18 months old) black spruce (Picea mariana) and tamarack (Larix laricina) seedlings for 34 days. Flooding...
Effects of variable nitrogen fertilization on growth, gas exchange, and biomass partitioning in black spruce and tamarack seedlings.Download
In order to compare the ability of black spruce (Picea mariana (Mill.) BSP) 1 and tamarack (Larix laricina (Du Roi) K. Koch) to adjust to variable edaphic conditions, 2 as found in natural peatlands, we varied nitrogen (N) fertilization of seedlings in a growth 3 chamber experiment over two...
Responses of black spruce (Picea mariana) and tamarack (Larix laricina) to flooding and ethylene treatments.Download
Black spruce (Picea mariana (Mill.) BSP) and tamarack (Larix laricina (Du Roi) K. Koch) are the predominant tree species in the boreal peatlands of Alberta, Canada, where low nutrient availability, low soil temperature and a high water table limit their growth. Effects of flooding for 28 days on...
