Book Description
This Special Issue of Water, Air and Soil Pollution offers contributions from the th 18 IUFRO workshop on Air Pollution Stress, Forest Responses to the Pollution st Climate of the 21 Century held in Edinburgh, Scotland, from September 21 to 23,1998. The meeting was held under the auspices of IUFRO, Research Group 7.04.00 chaired by Dr Kevin Percy of Canada. A new session structure was adopted to stimulate activity within the six working parties and a brief resume of these is presented at the front of this volume. The two, one-day plenary sessions were devoted to the two important air pollution issues, nitrogen deposition and ozone. Invited papers were augmented by a large and excellent contribution of poster papers. The final day comprised parallel Working Party Sessions with pre arranged speakers to stimulate discussions. One hundred and thirty one scientists attended, representing 20 countries and 7 IUFRO regions: Northern Europe, Central Europe, Eastern Europe, Mediterranean, North America, Asia and the Western Pacific.

Book Description
In February 1986, a forest soil degradation workshop was held at the University of British Colombia. The objectives of this workshop were to bring together people with the most up-to-date research knowledge and experience about forest soil degradation, and provide a forum for discussion with operational foresters and resource managers.

Book Description
At the end of the 1970s, when signs of destabilization of forests became visible in Eu rope on a large scale, it soon became obvious that the syndrome called "forest de cline" was caused by a network of interrelated factors of abiotic and biotic origin. All attempts to explain the wide-spread syndrome by a single cause, and there were many of them, failed or can only be regarded as a single mosaic stone in the network of caus es behind the phenomenon. Forest ecosystems are highly complex natural or quasi natural systems, which exhibit different structures and functions and as a conse quence different resilience to internal or external stresses. Moreover, forest ecosys tems have a long history, which means that former impacts may act as predisposing factors for other stresses. The complexity and the different history of forest ecosys tems are two reasons that make it difficult to assess the actual state and future devel opment of forests. But there are two other reasons: one is the large time scale in which forests react, the other is the idiosyncrasy of the reactions on different sites. Due to the slow reaction and the regional complexity of the abiotic environment of forest ecosys tems, a profound analysis of each site and region is necessary to identify the underly ing causes and driving forces when attempting to overcome the destruction of forest ecosystems.

Book Description
2009 Outstanding Academic Title, Choice This acclaimed textbook is the most comprehensive available in the field of forest ecology. Designed for advanced students of forest science, ecology, and environmental studies, it is also an essential reference for forest ecologists, foresters, and land managers. The authors provide an inclusive survey of boreal, temperate, and tropical forests with an emphasis on ecological concepts across scales that range from global to landscape to microscopic. Situating forests in the context of larger landscapes, they reveal the complex patterns and processes observed in tree-dominated habitats. The updated and expanded second edition covers • Conservation • Ecosystem services • Climate change • Vegetation classification • Disturbance • Species interactions • Self-thinning • Genetics • Soil influences • Productivity • Biogeochemical cycling • Mineralization • Effects of herbivory • Ecosystem stability
