Controls over monoterpene emissions from boreal forest conifers.
We investigated controls over the emission of monoterpenes from two species of boreal forest conifers, black spruce (Picea mariana Miller (B.S.P.)) and jack pine (Pinus banksiana Lamb). Monoterpenes are important in plants as carbon-based defensive compounds and in the atmosphere as photochemically reactive compounds that affect ozone and carbon monoxide concentrations. We examined ecological t...
متن کاملAntioxidant Potential of Bark Extracts from Boreal Forest Conifers
The bark of boreal forest conifers has been traditionally used by Native Americans to treat various ailments and diseases. Some of these diseases involve reactive oxygen species (ROS) that can be prevented by the consumption of antioxidants such as phenolic compounds that can be found in medicinal plants. In this study, ultrasonic assisted extraction has been performed under various solvent con...
متن کاملOrigin of Monoterpene Emissions from Boreal Tree Species: Determination of De Novo and Pool Emissions
Boreal forests are dominated by monoterpenes emitting tree species (Rinne et al., 2009). Traditionally the monoterpene emissions from coniferous tree species are assumed to originate as evaporation from large storage pools (Guenther et al., 1991). Thus their diurnal cycle would depend only on temperature. However, there is indication that a significant part of the monoterpene emission would ori...
متن کاملUncertainty in estimating carbon emissions from boreal forest fires
[ I ] The uncertainty in carbon einissions fi-om fire was esti~nated for the boreal region of Alaska over the 50 years of recorded wildfire. Building on previous work where carbon emissions were estimated using a geographic infonnation systems-based model, the uncertainty attached to the different parameters of the basic equation was assessed and propagated through the equation using Monte Carl...
