Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galápagos finches first made famous by Charles Darwin. In How and Why Species Multiply, they offered a complete evolutionary history of Darwin's finches since their origin almost three million years ago. Now, in their richly illustrated new book, 40 Years of Evolution, the authors turn their attention to events taking place on a contemporary scale. By continuously tracking finch populations over a period of four decades, they uncover the causes and consequences of significant events leading to evolutionary changes in species. The authors used a vast and unparalleled range of ecological, behavioral, and genetic data--including song recordings, DNA analyses, and feeding and breeding behavior--to measure changes in finch populations on the small island of Daphne Major in the Galápagos archipelago. They find that natural selection happens repeatedly, that finches hybridize and exchange genes rarely, and that they compete for scarce food in times of drought, with the remarkable result that the finch populations today differ significantly in average beak size and shape from those of forty years ago. The authors' most spectacular discovery is the initiation and establishment of a new lineage that now behaves as a new species, differing from others in size, song, and other characteristics. The authors emphasize the immeasurable value of continuous long-term studies of natural populations and of critical opportunities for detecting and understanding rare but significant events. By following the fates of finches for several generations, 40 Years of Evolution offers unparalleled insights into ecological and evolutionary changes in natural environments.

Mankind may be on the brink of extinction. This story begins with a family living in an underground bunker in the year 2052, while the world above is in total chaos. Nicholas and his family escaped their home in Denver and are now in New Mexico trying to survive an apocalyptic event caused by an approaching comet. The earth has been subject to natural and man-made disasters never before experienced by man. In the bunker, Nicholas reflects back on the past forty years of his life. He remembers the joyful times and the tragic events that changed everything. He relives the taking down of America by terrorist groups, the battle of Armageddon in the Middle East, natural disasters caused by great earthquakes and asteroids that changed the landscape around the world, and the great plague that killed a third of the world's population. In this doomsday scenario, 2052 Prophecies: The Last 40 Years puts readers in the bunker alongside Nicholas and his terrified family huddled together as the earth shakes violently from the comet's approach. Is it in the Prophecies that mankind will survive? Originally from Massachusetts,

The acclaimed author of Sniffer Dogs details the successful efforts of scientists to bring threatened animals back from the brink of extinction, perfect for animal lovers and reluctant nonfiction readers. With full-color photography. How could capturing the last wild California condors help save them? Why are some states planning to cull populations of the gray wolf, despite this species only recently making it off the endangered list? How did a decision made during the Civil War to use alligator skin for cheap boots nearly drive the animal to extinction? Back from the Brink answers these questions and more as it delves into the threats to seven species, and the scientific and political efforts to coax them back from the brink of extinction. This rich, informational look at the problem of extinction has a hopeful tone: all of these animals' numbers are now on the rise.

The Great New Wilderness Debate is an expansive, wide-ranging collection that addresses the pivotal environmental issues of the modern era. This eclectic volume on the varied constructions of “wilderness” reveals the recent controversies that surround those conceptions, and the gulf between those who argue for wilderness "preservation" and those who argue for "wise use." J. Baird Callicott and Michael P. Nelson have selected thirty-nine essays that provide historical context, range broadly across the issues, and set forth the positions of the debate. Beginning with such well-known authors as Ralph Waldo Emerson, Henry David Thoreau, John Muir, and Aldo Leopold, the collection moves forward to the contemporary debate and presents seminal works by a number of the most distinguished scholars in environmental history and environmental philosophy. The Great New Wilderness Debate also includes essays by conservation biologists, cultural geographers, environmental activists, and contemporary writers on the environment.

What ails Mother Earth? The answer can be found in the propensities of Man, her most gifted, but alas, also her most prodigal son. The world today may look to be the oyster to modern Man, with his faculties of creativity, inventiveness and enterprise. But looks are deceptive. Man has harnessed science and technology and also the new science of economics to bring about unprecedented prosperity, growth and amenities of life. All this, however, has come at a grievous cost to nature Ð in the anthropogenic maladies that we, in our reckless quest for ÔprogressÕ and comfort, have inflicted on the mother planet. Climate change and global warming; rampant exploitation of non-renewable fossil fuels belching out greenhouse gases; retreating glaciers; growing water, air and noise pollution; ocean acidification; ozone depletion; dwindling forests; imperilled biodiversity; and the growing menace of e-waste Ð all are stark symptoms of the seemingly inexorable degradation that human activities have wrought on the once-pristine environment of this living planet. We do not seem to learn from the fearsome records of myriad disasters and the five great extinctions that had stricken the earth in the past; what is worse, we seem to be heading mindlessly toward our collective doom of a sixth extinction, this time threatening to be caused by human-induced climate change. Time is running out, but all is still not lost. Initiatives have already been launched by conscientious world bodies, conferences and protocols to fight the hydra-headed monster of environmental pollution. What is needed is a broad-based general will Ð an Ôinformed consentÕ by us the conscious earthlings Ð to heal our beloved blue planet. The symptoms, the diagnostics and the line of cure, are all presented in this volume of highly readable and comprehensive analysis by an ecologist who has embraced ÔSave the EarthÕ as his mission in life.

In the decades following the first Earth Day in 1970, a generation has been enlightened about the unspeakable damage done to our planet. Federal, state, and local governments generated laws and regulations to control development and protect the environment. Local governments have developed environmental standards addressing their needs. The result-an ecologically incongruous pattern of land development known as urban sprawl. Local land use planners can have a greater effect on the quality of our environment than all of the federal and state regulators combined. Historically, they have existed on the periphery of land management. The author suggests that federal and state environmental regulators need to incorporate local governments into their environmental protection plans. Ecologically Based Municipal Land Use Planning provides easily understood, nuts and bolts solutions for controlling urban sprawl, emphasizing the integration of federal, state, and local land use plans. The book discusses ecological resources and provides practical solutions that municipal planners can implement immediately. It discusses the most recent scientific data, how to extract what is important, and how to apply it to the local land planning process. The author includes the application of the Geographic Information Systems (GIS) to problem solving. Despite compelling evidence and sound arguments favoring the implementation of an ecologically sensitive approach to land use planning, municipal planners, in general, remain skeptical. It will take considerably more encouragement and education to win them over completely. Ecologically Based Municipal Land Use Planning makes the case for sound land use policies that will reduce sprawl.

Joseph M. Forshaw, one of the world’s leading authorities on parrots, calls attention to the threats they face: they are one of the most endangered groups of birds, with a growing number of species nearing extinction. The main threats arise from habitat loss through deforestation and agricultural development and from the taking of birds for the international live-bird trade. Vanished and Vanishing Parrots brings together information on species that have become extinct in historical times with information on species that are in danger of becoming extinct to increase public awareness of the plight of these magnificent birds. Vivid colour plates by the wildlife artist Frank Knight draw attention to the spectacular species that we have lost or that could be lost. Forshaw’s work gives us fascinating insight into these endangered and extinct parrots. Vanished and Vanishing Parrots will be a valuable reference for scientific, ornithological and avicultural organisations, as well as individual lovers of birds and of illustrated natural history books.
