Each painting is accompanied by a description of the species with details of the habitat where it is found and a distribution map along with the name of the person who first described the species in scientific literature. A comprehensive Bibliography is also included listing thousands of individual books and papers that have been published on Australian frogs.
But the Great Turtle Race is just one of many tools marine conservationists use to inform people about the status, biology, and lives of the seven sea turtle species. Due to human actions, once-plentiful sea turtle population levels plummeted throughout much of the twentieth century, stabilizing somewhat only after Archie Carr and Jacques Cousteau popularized their plight. With Saving Sea Turtles, award-winning author James R. Spotila picks up where Carr and Cousteau left off, going inside the modern-day conservation movement to tell the tales of today’s sea turtle conservationists. He provides a complete overview of sea turtle biology and life cycles, discusses the human and natural world threats they face, and examines the new methods and technologies humans are using to save them. Throughout, Spotila dots the narrative with stories of real-life heroes who risk life and limb to understand, track, and conserve sea turtles across the globe.
Spotila has been at the forefront of sea turtle research and conservation for decades. His inspirational story of dedicated individuals, creative endeavors, and adventure reveals what is being done and what else we must do in order to ensure that these fascinating animals continue swimming in the oceans.
Dorcas and Gibbons discuss how frogs evolved, which species currently exist in the world, and why some have recently gone extinct. They reveal what frogs eat and what eats them, their role in cultures across the globe, why many populations are declining and what we can do to reverse this dangerous trend, why there are deformed frogs, and much more. They answer expected questions such as "What is the difference between a frog and a toad?" and "Why do some people lick toads?" and unexpected ones such as "Why do some frogs lay their eggs in the leaves of trees?" and "Do frogs feel pain?"
The authors’ easy-to-understand yet thorough explanations provide insight into the amazing biology of this amphibian group. In addressing conservation questions, Dorcas and Gibbons highlight the frightening implications of the current worldwide amphibian crisis, which many scientists predict will bring extinction rates experienced by frog species to levels not seen in any vertebrate animal group in millions of years.
Packed with facts and featuring two color galleries and 70 black-and-white photographs, Frogs: The Animal Answer Guide is sure to address the questions on the minds of curious naturalists.
Pterosaurs features some 200 stunning illustrations, including original paintings by Mark Witton and photos of rarely seen fossils. After decades of mystery, paleontologists have finally begun to understand how pterosaurs are related to other reptiles, how they functioned as living animals, and, despite dwarfing all other flying animals, how they managed to become airborne. Here you can explore the fossil evidence of pterosaur behavior and ecology, learn about the skeletal and soft-tissue anatomy of pterosaurs, and consider the newest theories about their cryptic origins. This one-of-a-kind book covers the discovery history, paleobiogeography, anatomy, and behaviors of more than 130 species of pterosaur, and also discusses their demise at the end of the Mesozoic.The most comprehensive book on pterosaurs ever published Features some 200 illustrations, including original paintings by the author Covers every known species and major group of pterosaurs Describes pterosaur anatomy, ecology, behaviors, diversity, and more Encourages further study with 500 references to primary pterosaur literature
Providing the first comprehensive treatment of North America’s tortoises, Biology and Conservation of North American Tortoises brings together leading experts to give an overview of tortoise morphology, taxonomy, systematics, paleontology, physiology, ecology, behavior, reproduction, diet, growth, health, and conservation. The contributors carefully combine their own expertise and observations with results from studies conducted by hundreds of other researchers. The result is a book that belongs in the library of every herpetologist.
