Leaf-level morphological and physiological responses of mature, winter-deciduous, shade-tolerant Acer saccharum Marsh. trees to gap formation caused by selection harvest were studied experimentally over a 2-year period. We found no evidence for either physiological stress or positive acclimation following gap creation during the 1-2-week post-harvest period. Rather, lower-canopy leaves showed g...

The stem of Acer tegmentosum has been widely used in Korea for the treatment of hepatic disorders. In this study, we investigated the bone protective effect of water extract of the stem of Acer tegmentosum (WEAT). We found that WEAT inhibits osteoclast differentiation induced by receptor activator of nuclear factor-κB ligand (RANKL), an essential cytokine for osteoclast differentiation. In oste...

Investigation on Seedling Emergence from Direct Seeding of Quercus Persica, Pistacia Atlantica and Acer Cineracens in Natural Conditions Ilam, Dalab Forests

Logging-induced changes from preindustrial (1930) to current conditions (2002) were studied in a landscape covering 13 550 ha in eastern Quebec. Age and types of forest cover were compared between 1930 and 2002 forest maps. In addition, we compared relative species abundance between living stems and coarse woody debris to study these changes at the stand scale. More than 90% of the 1930 preindu...

Leaf mass per area (LMA, g m(-2)) is an essential trait for modeling canopy function due to its strong association with photosynthesis, respiration and leaf nitrogen. Leaf mass per area, which is influenced by both leaf thickness and density (LMA = thickness × density), generally increases from the bottom to the top of tree canopies, yet the mechanisms behind this universal pattern are not yet ...
