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

"There is a lack of quiet in Sylvia that craves for action.... She knows that she is special and that she possesses unusual and varied abilities." -- From the Mossad's psychological evaluation of Sylvia RafaelWhen Moti Kfir, head of the Academy for Special Operations of the Mossad, first interviewed Sylvia Rafael in a coffee shop, he knew she would make a great combatant for Israel's intelligence agency. She was outgoing, resourceful, brilliant, and had a talent for bonding with others. When Kfir warned her that the mysterious job they'd met to discuss could be dangerous, she simply sat back comfortably in her chair and smiled. Sylvia Rafael is the page-turning account of a young, dedicated agent as told by the man who trained her. Drawing on extensive research and interviews, authors Ram Oren and Moti Kfir tell the story of Rafael's rise to prominence within the Mossad and her intelligence work trying to locate Ali Hassan Salameh -- the leader of Palestine's Black September organization and the mastermind behind the murder of eleven Israeli athletes at the 1972 Munich Olympic Games. Her team's misidentification of their mark would eventually lead to her arrest and imprisonment for murder and espionage.Now available in English for the first time, Sylvia Rafael offers new insight into the Israeli-Palestinian conflict, its history, and its human cost. It is a gripping, authentic spy story about a fearless defender of the Jewish people.

During the last decade, forest decline has become increasingly apparent. 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 on above-ground plant parts, the responses of soil to acid rain, and the changing nutrient availability, and the accompanying effects on plant metabolism and growth. The role of fungi, microorganisms and soil animals in the decline of these stands is also assessed. The volume is concluded with a synthesis evaluation of the influence of different factors, and their interactions on forest decline.
