"The Biology and Identification of the Coccidia (Apicomplexa) of Turtles of the World" is an invaluable resource for researchers in protozoology, coccidia, and parasitology, veterinary sciences, animal sciences, zoology, and biology. This first-of-its-kind work offers a taxonomic guide to apicomplexan parasites of turtles that enables easy parasite identification, with a summary of virtually everything known about the biology of each known parasite species. It is an important documentation of this specific area, useful to a broad base of readers, including researchers in biology, parasitology, animal husbandry, diseases of wild and domestic animals, veterinary medicine, and faculty members in universities with graduate programs in these areas.

There are about 330 turtle species on Earth; many are endangered, a growing number of species are kept as pets, and some are still used as food by humans. Turtles, like other vertebrate animals have many different kinds of parasites (viruses, bacteria, protozoa, worms, arthropods, and others). Coccidiosis in turtles has prevented large-scale turtle breeding, and represents a serious problem in need of control. This succinct and highly focused book will aid in that effort.
Offers line drawings and photomicrographs of each parasite from each hosts speciesProvides methods of identification and treatmentPresents a complete historical rendition of all known publications on coccidia (and their closest relatives) from all turtle species on Earth, and evaluates the scientific and scholarly merit of eachProvides a complete species analysis of the known biology of every coccidian described from turtles Reviews the most current taxonomy of turtles and their phylogenetic relationships needed to help assess host-specificity and evaluate what little cross-transmission work is available

R5,355 Discovery Miles 53 550 Ships in 18 - 22 working days

Most of the islands of the Caribbean have long histories of herpetological exploration and discovery, and even longer histories of human-mediated environmental degradation. Collectively, they constitute a major biodiversity hotspot - a region rich in endemic species that are threatened with extinction. This two-volume series documents the existing status of herpetofaunas (including sea turtles) of the Caribbean, and highlights conservation needs and efforts. Previous contributions to West Indian herpetology have focused on taxonomy, ecology and evolution, particularly of lizards. This series provides a unique and timely review of the status and conservation of all groups of amphibians and reptiles in the region. This volume introduces the issues particularly affecting Caribbean herpetofaunas, and gives an overview of evolutionary and taxonomic patterns influencing their conservation. Chapters focus on groups that have been relatively neglected in the Caribbean: amphibians and snakes. A major chapter describes the problem of invasive species of amphibians and reptiles in the West Indies. Three chapters then deal with islands of the Wider Caribbean that share many of the same problems but fall outside the West Indies biogeographic region: the Atlantic islands of the Bermuda group; the Dutch continental shelf islands of Aruba, Curacao and Bonaire, and the Neotropical islands of Trinidad and Tobago. The book will be useful to biologists and conservationists working in or visiting the Caribbean, and internationally as a summary of the current situation in this diverse and important region.

R4,223 Discovery Miles 42 230 Ships in 18 - 22 working days

Birds and reptiles have long fascinated investigators studying hearing and the auditory system. The highly evolved auditory inner ear of birds and reptiles shares many characteristics with the ear of mammals. Thus, the two groups are essential in understanding the form and function of the vertebrate and mammalian auditory systems. Comparative Hearing: Birds and Reptiles covers the broad range of our knowledge of hearing and acoustic communication in both groups of vertebrates. This volume addresses the many similarities in their auditory systems, as well as the known significant differences about hearing in the two groups.

As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.

The captivating and beautifully illustrated true story of snakes in America. 125 million years ago on the floodplains of North America, a burrowing lizard started down the long evolutionary path of shedding its limbs. The 60-plus species of snakes found in Sean P. Graham's American Snakes have this ancestral journey to thank for their ubiquity, diversity, and beauty. Although many people fear them, snakes are as much a part of America's rich natural heritage as redwoods, bald eagles, and grizzly bears. Found from the vast Okefenokee Swamp to high alpine meadows, from hardwood canopies to the burning bottom of the Grand Canyon, these ultimate vertebrates are ecologically pivotal predators and quintessential survivors. In this revelatory and engaging meditation on American snakes, Graham, a respected herpetologist and gifted writer, * explains the everyday lives of American snakes, from their daily routines and seasonal cycles to their love lives, hunting tactics, and defensive repertoires * debunks harmful myths about snakes and explores their relationship with humans * highlights the contribution of snakes to the American wilderness * tells tales of "snake people"-important snake biologists with inspiring careers Neither a typical field guide nor an exhaustive reference, American Snakes is instead a fascinating study of the suborder Serpentes. Brimming with intriguing and unusual stories-of hognose snakes that roll over and play dead, blindsnakes with tiny vestigial lungs, rainbow-hued dipsadines, and wave-surfing sea-snakes-the text is interspersed with scores of gorgeous full-color images of snakes, from the scary to the sublime. This proud celebration of a diverse American wildlife group will make every reader, no matter how skeptical, into a genuine snake lover.

R1,493 Discovery Miles 14 930 Ships in 10 - 15 working days

Archie Carr, one of the greatest biologists of the twentieth century, played a leading part in finding a new and critical role for natural history and systematics in a post-1950s world dominated by the glamorous science of molecular biology. With the rise of molecular biology came a growing popular awareness of species extinction. Carr championed endangered sea turtles, and his work reflects major shifts in the study of ecology and evolution. A gifted nature writer, his books on the natural history of sea turtles and their habitats in Florida, the Caribbean, and Africa entertained and educated a wide audience. Carr's conservation ethic grew from his field work as well as his friendships with the fishermen who supplied him with many of the stories he retold so engagingly. With Archie Carr as the focus, The Man Who Saved Sea Turtles explores the evolution of the naturalist tradition, biology, and conservation during the twentieth century.

This book looks at how an animal is organized to carry out a difficult task - that of feeding on plants. The complex adaptations necessary to enable animals to obtain nutrients successfully from a herbivorous diet are many. What structures are needed in the mouth, for example, or in the digestive system? How is behaviour adapted to allow an animal to survive and reproduce on a diet of plant material? For the first time, these problems are examined here purely from the perspective of the reptiles. Individual groups are looked at the structural, physiological and ecological adaptations of the herbivorous members are reviewed. The groups discussed include the modern reptiles, the lizards and the turtles and also extinct reptiles, the dinosaurs and the mammal-like reptiles. Common themes are teased out and arranged chronologically to help gain an understanding of the patterns of diversity change in the group. This book will be of great interest to researchers and students of zoology, palaeontology, evolution, ecology, functional anatomy and morphology.

The underlying theme of this book is that a widespread, taxonomically diverse group of animals, important both from ecological and human resource perspectives, remains poorly understood and in delcine, while receiving scant attention from the ecological and conservation community. This volume proposes a comprehensive overview of the world's river turtles' ecology, conservation, and management. It begins with a categorization of taxa which inhabit flowing water habitats followed by information on their evolutionary and physical diversity and biogeography. Within the framework of ecology, the authors discuss the composition of river turtle communities in different types of lotic habitats and regions, population dynamics, movements, reproductive characteristics and behavior, predators, and feeding relationships. In a conservation and management section, the authors identify and evaluate the nature and intensity of factors which threaten river turtle survival--almost all of which involve direct human exploitation or indirect effects of human induced habitat alteration and degradation. They then list and evaluate the various schemes which have been proposed or employed to halt declines and restore populations, and make recommendations for future management plans for specific species and regions. In closing, they state their viewpoint concerning future research directions and priorities, and an evaluation of future prospects for survival of the world's river turtle species.
