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.

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,

Gzimek’s Animal Life Encyclopedia is an internationally prominent scientific reference compilation, first published in German in the late 1960s, under the editorship of zoologist Bernhard Grzimek (1909-1987). In a cooperative effort between Gale and the American Zoo and Aquarium Association, the series is being completely revised and updated for the first time in over 30 years. Gale is expanding the series from 13 to 17 volumes, commissioning new color images, and updating the information while also making the set easier to use. The order of revisions is: Vol 8–11: Birds I–IV Vol 6: Amphibians Vol 7: Reptiles Vol 4–5: Fishes I–II Vol 12–16: Mammals I–V Vol 1: Lower Metazoans and Lesser Deuterostomes Vol 2: Protostomes Vol 3: Insects Vol 17: Cumulative Index Organized by taxonomy The overall structure of this reference work is based on the classification of animals into naturally related groups, a discipline known as taxonomy—the science through which various organisms are discovered, identified, described, named, classified, and catalogued. Starting with the simplest life forms, the lower metazoans and lesser deuterostomes, in volume 1, the series progresses through the more complex animal classes, culminating with the mammals in volumes 12–16. Volume 17 is a stand-alone cumulative index. Organization of chapters within each volume reinforces the taxonomic hierarchy. In the case of the Mammals volumes, introductory chapters describe general characteristics of all organisms in these groups, followed by taxonomic chapters dedicated to Order, Family, or Subfamily. Species accounts appear at the end of the Family and Subfamily chapters To help the reader grasp the scientific arrangement, each type of chapter has a distinctive color and symbol: ● =Order Chapter (blue background) ●▲ =Monotypic Order Chapter (green background) ▲ =Family Chapter (yellow background) =Subfamily Chapter (yellow background) Introductory chapters have a loose structure, reminiscent of the first edition. While not strictly formatted, Order chapters are carefully structured to cover basic information about member families. Monotypic orders, comprised of a single family, utilize family chapter organization. Family and subfamily chapters are most tightly structured, following a prescribed format of standard rubrics that make information easy to find and understand. Family chapters typically include: Thumbnail introduction Common name Scientific name Class Order Suborder Family Thumbnail description Size Number of genera, species Habitat Conservation status Main essay Evolution and systematics Physical characteristics Distribution Habitat Behavior Feeding ecology and diet Reproductive biology Conservation status Significance to humans Species accounts Common name Scientific name Subfamily Taxonomy Other common names Physical characteristics Distribution Habitat Behavior xii Grzimek’s Animal Life Encyclopedia • • • • • How to use this book Feeding ecology and diet Reproductive biology Conservation status Significance to humans Resources Books Periodicals Organizations Other Color graphics enhance understanding Grzimek’s features approximately 3,000 color photos, including approximately 1,560 in five Mammals volumes; 3,500 total color maps, including nearly 550 in the Mammals volumes; and approximately 5,500 total color illustrations, including approximately 930 in the Mammals volumes. Each featured species of animal is accompanied by both a distribution map and an illustration. All maps in Grzimek’s were created specifically for the project by XNR Productions. Distribution information was provided by expert contributors and, if necessary, further researched at the University of Michigan Zoological Museum library. Maps are intended to show broad distribution, not definitive ranges. All the color illustrations in Grzimek’s were created specifically for the project by Michigan Science Art. Expert contributors recommended the species to be illustrated and provided feedback to the artists, who supplemented this information with authoritative references and animal skins from University of Michgan Zoological Museum library. In addition to species illustrations, Grzimek’s features conceptual drawings that illustrate characteristic traits and behaviors. About the contributors The essays were written by scientists, professors, and other professionals. Grzimek’s subject advisors reviewed the completed essays to insure consistency and accuracy. Standards employed In preparing these volumes, the editors adopted a conservative approach to taxonomy, relying on Wilson and Reeder’s Mammal Species of the World: a Taxonomic and Geographic Reference (1993) as a guide. Systematics is a dynamic discipline in that new species are being discovered continuously, and new techniques (e.g., DNA sequencing) frequently result in changes in the hypothesized evolutionary relationships among various organisms. Consequently, controversy often exists regarding classification of a particular animal or group of animals; such differences are mentioned in the text. Grzimek’s has been designed with ready reference in mind and the editors have standardized information wherever feasible. For Conservation status, Grzimek’s follows the IUCN Red List system, developed by its Species Survival Commission. The Red List provides the world’s most comprehensive inventory of the global conservation status of plants and animals. Using a set of criteria to evaluate extinction risk, the IUCN recognizes the following categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Conservation Dependent, Near Threatened, Least Concern, and Data Deficient.
