The Elusive Boreal Forest Thaumarchaeota
In recent years, Archaea have, with increasing frequency, been found to colonize both agricultural and forest soils in temperate and boreal regions. The as yet uncultured group I.1c of the Thaumarchaeota has been of special interest. These Archaea are widely distributed in mature vegetated acidic soils, but little has been revealed of their physiological and biological characteristics. The I.1c...
متن کامل6 . Boreal Forest
The boreal forest biome occupies 13 x I06km1. It comprises approximately 25% of the world's forest land (Olson et al. 1983; Apps et al. 1993) and includes 2.6 x 106km1 of peatlands (Gorham 1991). Changes in the extent or functioning of the boreal forest wuld substantially modify global climate through (1) release of its large stocks of soil carbon (Post et al. Boreal forests have also been impl...
متن کاملForest fire effects on mercury deposition in the boreal forest.
Particulate Hg (pHg) is a component of smoke from biomass burning and has the potential for local redeposition. Throughfall (precipitation collected beneath a conifer or deciduous canopy) and open precipitation samples were collected pre- and postfire in 2005 and 2006 using passive precipitation collectors across the Superior National Forest, located in northern Minnesota, USA. Samples were col...
متن کاملResidual Long-Term Effects of Forest Fertilization on Tree Growth and Nitrogen Turnover in Boreal Forest
The growth enhancing effects of forest fertilizer is considered to level off within 10 years of the application, and be restricted to one forest stand rotation. However, fertilizer induced changes in plant community composition has been shown to occur in the following stand rotation. To clarify whether effects of forest fertilization have residual long-term effects, extending into the next rota...
متن کاملIs Alaska’s Boreal Forest Now Crossing a Major Ecological Threshold?
Daniel H. Mann*§ Many boreal forests grow in regions where climate is now warming rapidly. Changes in T. Scott Rupp† these vast, cold forests have the potential to affect global climate because they store huge Mark A. Olson† and amounts of carbon and because the relative abundances of their different tree species Paul A. Duffy‡ influence how much solar radiation reflects back to space. Both the...
