The boreal forest is one of the world's great ecosystems, stretching across North America and Eurasia in an unbroken band and containing about 25% of the world's closed canopy forests. The Kluane Boreal Forest Ecosystem Project was a 10-year study by nine of Canada's leading ecologists to unravel the impact of the snowshoe hare cycle on the plants and the other vertebrate species in the boreal forest. In much of the boreal forest, the snowshoe hare acts as a keystone herbivore, fluctuating in 9-10 year cycles, and dragging along secondary cycles in predators such as lynx and great-horned owls. By manipulating the ecosystem on a large scale from the bottom via fertilizer additions and from th...

How did rodent outbreaks in Germany help to end World War I? What caused the destructive outbreak of rodents in Oregon and California in the late 1950s, the large population outbreak of lemmings in Scandinavia in 2010, and the great abundance of field mice in Scotland in the spring of 2011? Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and in Population Fluctuations in Rodents, Charles J. Krebs sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research. Krebs has synthesized the research in this area, focusing mainly on the voles and lem...
Football is a game of numbers--fourth and inches, the three-man rush, a two point conversion, first down. Even with the obvious numbers in the statistics, rules and game situations, the players' uniform numbers themselves have become part of professional football and its lore. NFL players, like modern-day gladiators, are fitted head-to-toe in protective gear, obscuring even their faces from their most loyal fans. They have become largely identifiable through their uniform numbers. You cannot conjure up Larry Csonka without seeing the number 39 crashing through the line of scrimmage, or recall Lawrence Taylor without imagining the fear his 56 inspired in opposing quarterbacks. This comprehensive reference work lists all 32 current franchises of the NFL and includes brief team histories, statistics and interesting facts. Each chapter ends with an all-time numerical roster listing the numbers 1 through 99 (in some cases beginning with 00) and everyone, from Hall-of-Famer to replacement player, who has ever worn the corresponding number for that club. Four appendices are included.

The vast temperate rainforests of coastal British Columbia are world renowned, but much less is known about the other rainforest located 500 kilometres inland along the western slopes of the interior mountains. The unique integration of continentality and humidity in this region favours the development of lush rainforest communities that incorporate both coastal and boreal elements. In British Columbia's Inland Rainforest, scientists bring together, for the first time, a broad spectrum of information about this distinctive ecosystem. They also consider the ecological consequences of human activities in the rainforest and present strategies for its management and conservation.
"This edited collection considers how landscapes designed by humans contain multiple ecosystems for animals and plants. Using quantitative methods, the contributors explain how to model what components of a landscape are critical to species of interest"--
