The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to...

This comprehensive handbook covers all the rodents occurring in Southern, Central, East and West Africa, south of the Sahara. Genus and species accounts include diagnostic descriptions, systematics and taxonomy, biogeographical environment, fossil species, photographs of skull and mandible, illustrations of molar dentition, photographs of live animals, distribution maps and tables of standard museum measurements.

'Cannabinoids' is a broad term covering a group of natural products from Cannabis sativa, one of which locks on to specific receptors - protein molecules on the surface of cells - known as cannabinoid receptors. Over the past decades scientists have found that cannabinoid receptors and their endogenous ligands, the endocannabinoids, are involved in a vast array of physiological functions, including helping to control brain activity, energy metabolism, heart function, the immune system and even reproduction.

In Cannabinoids, Vincenzo Di Marzo has assembled contributions from...

From the ancient Egyptian cat goddess, Bastet, to the prophet Muhammad's favorite cat, Muezza, and our contemporary obsession with online cat videos, felines have long held a place of honor in their human counterparts' homes and cultures. But the domestic cat is just one of many feline species, and in The Wild Cat Book cat experts Fiona and Mel Sunquist introduce us to the full panoply of the purring, roaring feline tribe.

Illustrated throughout with Terry Whittaker's spectacular color photographs as well as unique photos from biologists in the field--some the highest quality...

This book brings together scientific evidence and experience relevant to the practical conservation of bats. The authors worked with an international group of bat experts and conservationists to develop a global list of interventions that could benefit bats. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bats quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bat conservation actions throughout the world. Bat Conservation is the fifth...

In In the Company of Bears, originally published in hardcover as Out on a Limb, Ben Kilham invites us into the world he has come to know best: the world of black bears.

For decades, Kilham has studied wild black bears in a vast tract of Northern New Hampshire woodlands. At times, he has also taken in orphaned infants-feeding them, walking them through the forest for months to help them decipher their natural world, and eventually reintroducing them back into the wild. Once free, the orphaned bears still regard him as their mother. And one of these bears, now a...

A firsthand exploration of the extraordinary abilities and surprising, sometimes life-saving talents of "working dogs"--pups who can sniff out drugs, find explosives, even locate the dead--as told through the experiences of a journalist and her intrepid canine companion, which The New York Times calls "a fascinating, deeply reported journey into the...amazing things dogs can do with their noses."

There are thousands of working dogs all over the US and beyond with incredible abilities--they can find missing people, detect drugs and bombs, pinpoint unmarked graves of...

Meet Greg. He's a stocky guy with an outsized swagger. He's been the intimidating yet sociable don of his posse of friends--including Abe, Keith, Mike, Kevin, Torn Trunk, and Willie. But one arid summer the tide begins to shift and the third-ranking Kevin starts to get ambitious, seeking a higher position within this social club. But this is no ordinary tale of gangland betrayal--Greg and his entourage are bull elephants in Etosha National Park, Namibia, where, for the last twenty-three years, Caitlin O'Connell has been a keen observer of their complicated friendships.

In Elephant...

In recent years a new field of study has arisen called developmental biology. The term developmental biology is really a new name for embryology; it is, however, used to denote the molecular approach to the study of developing systems. In this book we have tried wherever possible to blend the older information of classical embryology and in particular organogeny with the newer concepts of developmental biology. The original intention was to cover all the tissues of the body in this book. However, it soon became obvious that it was not possible to do this within one volume. Therefore we...

The book provides the most comprehensive review of lamprey biology since Hardisty and Potter's five-volume "The Biology of Lampreys" published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey...

The book, entitled "Welfare of farmed fish in present and future production systems", summarises the view of more than 80 experts in the field of fish welfare, collected over a period of more than five years in an international network entitled "Welfare of Fish in European Aquaculture" (Cost action 867), which was sponsored by the COST Office. COST is the acronym for European Cooperation in Science and Technology. During the time of the action a shift became evident in the general perception of fish welfare. It now not only includes variables with very direct effects on growth, and thereby...

Unlike other barnyard animals, which pull plows, give eggs or milk, or grow wool, a pig produces only one thing: meat. Incredibly efficient at converting almost any organic matter into nourishing, delectable protein, swine are nothing short of a gastronomic godsendyet their flesh is banned in many cultures, and the animals themselves are maligned as filthy, lazy brutes.
As historian Mark Essig reveals in "Lesser Beasts," swine have such a bad reputation for precisely the same reasons they are so valuable as a source of food: they are intelligent, self-sufficient, and omnivorous. What s...

In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information...

Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling...

In "Part of the Pride," Kevin Richardson, recently dubbed "The Lion Man" on 60 Minutes, tells the story of how he grew from a young boy who loved animals to become a man able to cross the divide between humans and predators, looking some of the world's most dangerous animals directly in the eye, playing with them and even kissing them on the nose-all without ever being attacked or injured. As a self-taught animal behaviorist, Richardson has broken every safety rule known to humans when working with these wild animals. Flouting common misconceptions that breaking an animal's spirit with...
