The radial increases in wood specific gravity known in many tree species have been interpreted as providing mechanical support in response to the stresses associated with wind loading. This interpretation leads to the hypothesis that individuals reaching the canopy should (1) be more likely to have radial increases in specific gravity and (2) exhibit greater increases than ...

The even-aged northern hardwood forests of the Upper Great Lakes Region are undergoing an ecological transition during which structural and biotic complexity is increasing.

Species composition of temperate forests vary with successional age and seems likely to change in response to significant global climate change. Because photosynthesis rates in co-occurring tree species can differ in their sensitivity to environmental conditions, these changes in species composition are likely to alter the carbon dynamics of temperate forests.

Other fields failed to return to forest unless they were planted. In one such area, nine acres were planted with baldcypress in 1956 by MeadWestvaco near Walterboro, SC. Seedlings were planted on an 8- by 8-foot spacing. ... In addition to baldcypress, the stand now contains red maple (Acer rubrum L.), black willow ( Salix ...

In red maple (Acer rubrum), there was n.s.d. in higher heating value (HHV) between stem wood and branch wood or between stem bark and branch bark. In post oak (Quercus stellata) the HHV of stem bark was significantly higher than that of branch bark, but there was n.s.d. between stem wood and branch wood. For both species the wood had a significantly higher ...
