Longleaf, Far as the Eye Can See: A New Vision of North America's Richest Forest
ISBN: 9780807835753 / Angielski / Twarda / 192 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Longleaf forests once covered 92 million acres from Texas to Maryland to Florida. These grand old-growth pines were the "alpha tree" of the largest forest ecosystem in North America and have come to define the southern forest. But logging, suppression of fire, destruction by landowners, and a complex web of other factors reduced those forests so that longleaf is now found only on 3 million acres. Fortunately, the stately tree is enjoying a resurgence of interest, and longleaf forests are once again spreading across the South. Blending a compelling narrative by writers Bill Finch, Rhett...

Tropical Montane Cloud Forests
ISBN: 9781461275640 / Angielski / Miękka / 407 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Until relatively recently the valuable tropical montane cloud forests (hereaf- ter usually referred to as TMCFs) of the world had scarcely come under the assaults experienced by the downslope montane and lowland forests. TMCFs are not hospitable environments for human occupation, and their remoteness (except in places near Andean high mountain settlements and in the Ethiopian Highlands) and difficult terrain have given them de facto protection. The ad- jacent upper montane rain forests have indeed been under assault for timber, fuelwood, and for conversion to grazing and agriculture for many...

Advances in Soil Science: Volume 20
ISBN: 9781461277248 / Angielski / Miękka / 314 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The key to sustaining the soil resource base is to maintain, or enhance, soil quality. Soil quality cannot be seen or measured directly from the soil alone but is inferred from soil characteristics and soil behavior under defined conditions. In essence, the quality of soils is analogous to the health of humans, and just as there is no single characteristic that can be measured to quantify a person's health, there is no single measurement that can quantify soil quality. However, there are certain characteristics, particularly when considered together, that are good indicators. Soil quality,...

John Sculley In the short history of personal computing, the task of the software programmer has been one of the least recognized-but one of the most significant-in the industry. In addition to defining the prob- lems, and presenting the solutions, the software programmer is con- fronted with the challenge of having to predict what combination of ideas and technologies will move the industry forward in the most compelling way. Even though we've seen the development of tremendous applications in a surprisingly short period of time, the most difficult problems often surface when we try to...

The potential for humans to alter Earth's atmosphere has been recognized since the end of the 19th century when Arrhenius estimated that a doubling of atmospheric carbon dioxide could alter the atmospheric radiation balance and raise average global temperature. Today, atmospheric CO concentrations play an important part in the 2 climate-change debate. Sources and sinks of CO associated with land use can be 2 significant determinants of the rate and magnitude of atmospheric CO change. 2 Combustion of...

Reintegrating Fragmented Landscapes: Towards Sustainable Production and Nature Conservation
ISBN: 9781461392163 / Angielski / Miękka / 332 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Social historians will look back on the 1980s as a period when a global consciousness of the environment developed. Stimulated by major issues and events such as oil and chemical spills, clearing of rainforests, pollu tion of waterways, and, towards the end of the decade, concern over the greenhouse effect, concern for the environment has become a major social and political force. Unfortunately, the state of the environment and its future manage ment are still very divisive issues. Often, at a local level, concern for the environment is the antithesis of development. The debate usually...

Physiological Ecology of the Alpine Timberline: Tree Existence at High Altitudes with Special Reference to the European Alps
ISBN: 9783642671098 / Angielski / Miękka / 140 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In the European Alps the importance of forests as protection against ava- lanches and soil erosion is becoming ever clearer with the continuing increase in population and development of tourism. The protective potential of the moun- tain forests can currently only be partially realised because a considerable propor- tion of high-altitude stands has been destroyed in historical times by man's extensive clearing ofthe forests. The forests still remaining are of limited effec- tiveness, due to inadequate density of trees and over-maturity. Considerable efforts, however, are now being made in the...
