Interacting Effects of Multiple Stresses on Growth and Physiological Processes in Northern Forest Trge (IPCC) of the United Nations concluded that “the balance of evidence suggests a discernible human influence on global climate,” and that “further accumulation of greenhouse gases will commit the earth irreversibly to global climate change with its consequent ecological, economic, and social disru

Tree Health and Physiology in a Changing Environment) and explains much about how mature trees function through their unique structure. When the tree begins its life, it is mostly leaf in mass (Fig. 7.1a). As a tree grows in stature, it becomes mostly stem in mass and the foliage represents only a few percent of the total mass. Roots remain relativel

Atmospheric Deposition Effects on Surface Waters, Soils, and Forest Productivity the earliest acidic deposition research found that fish populations in some lakes and streams in the Adirondack Mountains of NY had been eliminated by acidification (Schofield, 1976). In the 1980s, research in the U.S. expanded greatly through the National Acid Precipitation Assessment Program (NAP

Nitrogen Saturation in Experimental Forested Watersheds which translates to “without life” because free N is incapable of supporting life: a fitting name for this element given the paradoxes it presents to society and its role in global ecology. Despite being the most abundant element in the atmosphere, usually quoted as 78% by volume, primarily as N.,

Effects of Climate Change on Forest Insect and Disease Outbreaks dioxide (CO.) levels (.; .; .; .; .). January temperatures are projected to rise as much as 12°C and July temperatures as much as 9°C over temperatures simulated at ambient CO. (.). Projections of precipitation are quite variable over the region, ranging from 71 to 177% of ambient levels in January

Forest Responses to Changing Climate: Lessons from the Past and Uncertainty for the Futuresiderable evidence indicates that increasing concentrations of carbon dioxide and other greenhouse gases in the earth’s atmosphere will lead to near-term warming, perhaps as much as 2 to 4°C in northeastern North America. Given that the distribution of vegetation on earth has varied with past climat
