Characterizing the use of carbon (C) reserves in trees is important for understanding regional and global C cycles, stress responses, asynchrony between photosynthetic activity and growth demand, and isotopic exchanges in studies of tree physiology a

The effects of elevated CO2 on nutrient cycling and selected belowground processes in the closed-canopy sweetgum plantation were assessed as part of a free-air CO2 enrichment (FACE) ex- periment at Oak Ridge, Tennessee. We hypothesized that nitrogen

We examined the timing of root elongation intensity (REI) – the production of newly elongating roots measured in length per unit soil volume per unit time – in a mature white oak-chestnut oak forest in Tennessee, USA, over a 4-year period. We use

How ecosystems adapt to climate changes depends in part on how individual trees allocate resources to their components. A review of research using tree seedlings provides some support for the hypothesis that some tree species respond to exposure to d

Scientists who study urban ecosystems have emphasized the importance of the so-called “ecological footprints” of population centers, which extend far beyond their political or physical boundaries (Rees, 1997; Wackernagel and Rees, 1995; Walker et

In order to examine the below ground response of a mature upland hardwood forest in the southeastern U.S., to increases and decreases in water inputs, the gross production, mortality, and net production of fine roots were examined over the first and

This paper integrates the results of a number of studies on the effects of cloudwater and ozone (O{sub 3}) on red spruce (Picea rubens Sarg.) seedlings, saplings, and mature trees at Whitetop Mountain, VA, over a 3-yr period. These investigations con
