The decline and expected elimination of hemlock from northeastern .

The decline and expected elimination of hemlock from northeastern . forests is changing forest structure, function, and assemblages of associated species. The adelgid has reset successional sequences, homogenized biological diversity at landscape scales, altered hydrological dynamics, and changed forest stands from carbon sinks into carbon sources.

Livestock graze Indian forests to varying extents but their impact on wild native ungulates is rarely understood. Negative impacts of sympatric livestock on chital (Axis axis) demography and food availability were assessed and compared in the Gir Forest, India, at different spatio-temporal scales.

The great Christian thinker and writer . Lewis, author of "Mere Christianity" and "The Chronicles of Narnia," also wrote an engaging little book called "The Abolition of Man: How Education Develops Man’s Sense of Morality. I serve as president of a Christian university in an increasingly post-Christian culture.

Over the last few years, a number of attempts have been made to evaluate the potential effects of forest dieback on the timber sector and the environment in economic terms.

The decline in forest health was often reported to be associated with air pollution. The present study on Norway spruce stands in the Fichtelgebirge analyses various processes interacting within forest ecosystems. It covers transport and deposition of air pollutants, the direct effects of pollutants During the last decade, forest decline has become increasingly apparent.

Forest Declines These soluble species impact food production on naturally acidic soils and contribute to forest decline in areas influenced by acid rain.

Concern with the effects of air pollution has increased progressively because of its possible association with widespread synchronized mortality of trees (Plochmann, 1984; Schuett and Cowling, 1985; McLaughlin, 1985; Smith, 1995; Little, 1995). Typical symptoms of forest decline in conifers include chlorosis, loss of needles, bud mortality, growth inhibition, bark injury, resin exudation, and tree mortality. These soluble species impact food production on naturally acidic soils and contribute to forest decline in areas influenced by acid rain.

Forest dieback (also "Waldsterben", a German loan word) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or due to conditions like acid rain and drought. Two of the nine tipping points for major climate changes forecast for the next century, are directly related to forest diebacks. Forest dieback refers to the phenomenon of a stand of trees losing health and dying without an obvious cause.
