All life on Earth is held hostage by a desperate and ruthless alien race in this “hard-hitting apocalyptic thriller” from award-winning author Scott Mackay (Booklist). The Tarsalans came to Earth hoping to settle on the planet alongside a sympathetic human race. But after years of delicate negotiations, their patience reaches the breaking point and they decide to make their case for immigration terrifyingly clear—by enveloping the planet in a green sphere which blocks out all sunlight. Without energy from the sun, the Earth—and every living thing on it—is doomed. Soon, civilization breaks down as the instinct for individual survival shreds humanity’s common bonds. It appears mankind may destroy itself even before the Phytosphere does. The only hope against catastrophe lies in the troubled connection between two brothers—one stranded at a lunar base on the moon, the other trapped on the dying Earth... “Deftly juggling hard sci-fi and a bleak tale of post-apocalyptic survival” Scott Mackay once again offers an electrifying sci-fi tale of “high-tech intrigue and old-fashioned suspense” (Publishers Weekly).
Insect and disease issues are often specific to the Mediterranean forest systems rather than shared with the temperate forests. In addition to the specific native insects and diseases, the forests are subject to the invasion of exotic species. The forests are also at risk from high degrees of human activity, including changing patterns of forest fires, land management activities, intensive plantation forestry using introduced timber species from other Mediterranean climate zones, and atmospheric deposition. Combined with elements of global climate change that may disproportionately affect Mediterranean climate systems, this creates a number of significant management issues that are unique to the Mediterranean forests. It is our goal that the information contained in this volume will contribute to understanding the unique aspects of Mediterranean forest systems and to protecting these critical resources.

This publication offers a comprehensive look at the management of oaks in urban areas. As development moves into oak woodland areas, more and more oaks are becoming "urban" oaks. Oaks are highly valued in urban areas for their aesthetic, environmental, economic and cultural benefits. However, significant impacts to the health and structural stability of oaks have resulted from urban encroachment. Changes in environment, incompatible cultural practices, and pest problems can all lead to the early demise of our stately oaks. Using this book you'll learn how to effectively manage and protect oaks in urban areas - existing oaks as well as the planting of new oaks. Three key areas are addressed: selection, care, and preservation. You'll learn how cultural practices, pest management, risk management, preservation during development, and genetic diversity can all play a role in preserving urban oaks. Arborists, urban foresters, landscape architects, planners and designers, golf course superintendents, academics, and Master Gardeners alike will find this to be an invaluable reference guide.
