Book Description
The Dissection of Vertebrates, Second Edition, provides students with a manual that combines pedalogical effective text with high-quality, accurate, and attractive visual references. Using a systemic approach within a systematic framework for each vertebrate, this book covers several animals commonly used in providing an anatomical transition sequence. Seven animals are covered: lamprey, shark, perch, mudpuppy, frog, pigeon, and cat. This updated version include a revised systemic section of the introductory chapter; corrections to several parts of the existing text and images; new comparative skull sections included as part of the existing vertebrates; and a companion site with image bank. This text is designed for 2nd or 3rd year university level comparative vertebrate anatomy courses. Such courses are usually two-semester courses, and may either be a required course or an elective. It is typically a required course for Biology and Zoology majors, as well as for some Forensics and Criminology programs, and offered as an elective for many other non-zoology science majors. Winner of the NYSM Jury award for the Rock Dove Air Sacs, Lateral and Ventral Views illustration Expertly rendered award-winning illustrations accompany the detailed, clear dissection direction Organized by individual organism to facilitate classroom presentation Offers coverage of a wide range of vertebrates Full-color, strong pedagogical aids in a convenient lay-flat presentation Expanded and updated features on phylogenic coverage, mudpuppy musculature and comparative mammalian skulls

Book Description
The most up-to-date and authoritative illustrated guide to the marvelous flying reptiles that dominated the skies of the Mesozoic for 160 million years Once seen by some as evolutionary dead-enders, pterosaurs were vigorous winged reptiles capable of thriving in an array of habitats and climates, including polar winters. The Princeton Field Guide to Pterosaurs transforms our understanding of these great Mesozoic archosaurs of the air. This incredible guide covers 115 pterosaur species and features stunning illustrations of pterosaurs ranging in size from swallows to small sailplanes, some with enormous, bizarre head crests and elongated beaks. It discusses the history of pterosaurs through 160 million years of the Mesozoic—including their anatomy, physiology, locomotion, reproduction, growth, and extinction—and even gives a taste of what it might be like to travel back to the Mesozoic. This one-of-a-kind guide also challenges the common image of big pterosaurs as ultralights that only soared, showing how these spectacular creatures could be powerful flappers as heavy as bears. Features detailed species accounts of 115 different kinds of pterosaurs, with the latest size and mass estimates Written and illustrated by the acclaimed researcher and artist who helped to redefine the anatomy and flight performance of pterosaurs Covers everything from pterosaur biology to the colorful history of pterosaur paleontology Includes dozens of original skeletal drawings and full-color life studies

Book Description
Delve into the lives of owls with this collection of photographs and information by award-winning author and wildlife photographer Stan Tekiela. They are silent and beautiful. They symbolize knowledge and mystery. Owls are among the most popular and beloved animals in the world. Yet most are nocturnal, so an owl sighting is a remarkable event, one worthy of remembering and sharing with others. Award-winning author, naturalist, and wildlife photographer Stan Tekiela believes that owls are intriguing birds. He spent more than 20 years traveling across the country to observe and photograph the various species, from the Great Horned Owl to the extremely uncommon Ferruginous Pygmy-Owl. He documented every aspect of the owl’s life: major events such as courtship and mating, as well as everyday activities like hunting and sleeping. The result is a striking portrayal of these amazing raptors in Owls. Stan’s extraordinary photographs depict the birds of prey in a new, unique fashion. His fascinating text is drawn from detailed research and personal observations. Presented with headings and short paragraphs, the coffee-table book is pleasurable to browse and easy to read. “They are strikingly beautiful creatures and incredible hunters,” says Stan. “Owls are among my favorite birds to study and to photograph.” Unmatched by any other book on the market, Owls is a must-have for bird watchers, wildlife enthusiasts, and nature lovers.
