Ernst and Lovich’s thoroughly revised edition of this classic reference provides the most updated information ever assembled on the natural histories of North American turtles. From diminutive mud turtles to giant alligator snappers, two of North America’s most prominent experts describe the turtles that live in the fresh, brackish, and marine waters north of Mexico. Incorporating the explosion of new scientific information published on turtles over the past fifteen years—including the identification of four new species—Ernst and Lovich supply comprehensive coverage of all fifty-eight species, with discussions of conservation status and recovery efforts. Each species account contains information on identification, genetics, fossil record, distribution, geographic variation, habitat, behavior, reproduction, biology, growth and longevity, food habits, populations, predators, and conservation status. The book includes range maps for freshwater and terrestrial species, a glossary of scientific names, an extensive bibliography for further research, and an index to scientific and common names. Logically organized and richly illustrated—with more than two hundred color photographs and fifty-two maps— Turtles of the United States and Canada remains the standard for libraries, museums, nature centers, field biologists, and professional and amateur herpetologists alike.

This scientific masterpiece reveals many aspects of the lives of marsupial frogs and closely allied genera. Native to Central and South America, these amphibians differ from other frogs in that they protect their eggs after oviposition by either adhering them to the female’s back or placing them in a specialized dorsal pouch (thus the common name, marsupial frog). During mating, the male typically collects the eggs from the female with his feet—often one at a time and always out of water—fertilizes them, and then tucks them into the female’s pouch or attaches them to her back. In some species these eggs hatch as tadpoles, but most emerge as miniatures of the adults. Even among the tadpoles there is remarkable divergence, with some behaving in the typical manner (feeding and metamorphosing), whereas others forego all feeding until they metamorphose. In Marsupial Frogs, William E. Duellman’s synthesis of all that is known about the unique family Hemiphractidae is largely based on decades of his own careful laboratory and field study. He reveals the diversity of exotic color patterns and the frogs' geographic distributions by providing more than 200 photographs, illustrations, and maps. This exceptional tome should find its way into the libraries of serious herpetologists, tropical biologists, and developmental biologists. Included in this book are • A molecular phylogeny of the family Hemiphractidae• A thorough osteological analysis• A review of external morphological features• An overview of the evolution of reproductive modes• A biogeographic synthesis• Keys to genera and species• Diagnosis and thorough description of each species of marsupial frog• Colored physiographic maps depicting species distributions

In a riveting narrative set in fifteenth-century Korea, two brothers discover a shared passion for kites. Kee-sup can craft a kite unequaled in strength and beauty, but his younger brother, Young-sup, can fly a kite as if he controlled the wind itself. Their combined skills attract the notice of Korea's young king, who chooses Young-sup to fly the royal kite in the New Year kite-flying competition--an honor that is also an awesome responsibility. Although tradition decrees, and the boys' father insists, that the older brother represent the family, both brothers know that this time the family's honor is best left in Young-sup's hands. This touching and suspenseful story, filled with the authentic detail and flavor of traditional Korean kite fighting, brings a remarkable setting vividly to life. AUTHOR'S NOTE.

New York Times Bestseller A Summer Reading Pick for President Barack Obama, Bill Gates, and Mark Zuckerberg From a renowned historian comes a groundbreaking narrative of humanity’s creation and evolution—a #1 international bestseller—that explores the ways in which biology and history have defined us and enhanced our understanding of what it means to be “human.” One hundred thousand years ago, at least six different species of humans inhabited Earth. Yet today there is only one—homo sapiens. What happened to the others? And what may happen to us? Most books about the history of humanity pursue either a historical or a biological approach, but Dr. Yuval Noah Harari breaks the mold with this highly original book that begins about 70,000 years ago with the appearance of modern cognition. From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens integrates history and science to reconsider accepted narratives, connect past developments with contemporary concerns, and examine specific events within the context of larger ideas. Dr. Harari also compels us to look ahead, because over the last few decades humans have begun to bend laws of natural selection that have governed life for the past four billion years. We are acquiring the ability to design not only the world around us, but also ourselves. Where is this leading us, and what do we want to become? Featuring 27 photographs, 6 maps, and 25 illustrations/diagrams, this provocative and insightful work is sure to spark debate and is essential reading for aficionados of Jared Diamond, James Gleick, Matt Ridley, Robert Wright, and Sharon Moalem.
