Twenty elegant essays examine the behavior of various creatures -- from hummingbirds to bumblebees, thatcher ants to wrens, owls to woodrats to wasps -- and the remarkable ways in which they have adapted to their world. The author clearly recognizes that the lives of these species are the threads that weave together the natural world, and he warns that the loss of any one species inevitably diminishes all others -- including our own. Best of all, though, Howard Ensign Evans has never lost his sense of wonder, and these pages are sure to evoke a sense of delight and curiosity in the reader as well.

In this book internationally known experts provide a comprehensive view of current knowledge of social insect biology including much previously unpublished information. Particular emphasis is given to the relationships between social insects and humans; sections are devoted to economically important social insects, pollination, foraging, and the role of insects in ecosystems and agroecosystems. The authors also discuss communication, behavior and caste within insect colonies. A special section focuses on the neurobiology of social insects. A series of papers considers the presocial insects, which live in family groups but without caste differences. Also well represented are the fields of sociobiology and the origins and evolution of social behavior. The book will be valuable to agricultural scientists as well as to entomologists, sociobiologists, ecologists, ethologists, and natural historians. Endocrinologists and neurobiologists will also find important new material.

Utilizing detailed descriptions and more than 300 high-quality color anatomic drawings, Guide to the Dissection of the Dog, 8th Edition walks you through how to perform precise canine dissections while developing your understanding of basic mammalian structure and specific canine features. Each chapter offers self-contained guidance on the dissection of a specific body part, allowing you to perform dissections in whatever sequence your choose. Other helpful features include: an emphasis on the anatomical knowledge and terminology from the Nomina Anatomica Veterinaria; a comprehensive list of all figures and tables; and an extensive list of references for further research. In all, this one-of-a-kind canine dissection manual is the resource you need to better understand and review what you are learning in your first-year dissection course. The only hands-on canine dissection guide available reinforces the information that you learn in your mandatory first-year dissection course. Body part organization follows the order of dissection commonly taught in veterinary schools and enables you to perform dissections in any sequence. More than 300 high-quality color anatomic drawings guide each step-by-step dissection procedure. Radiographs, CAT scans and MR images appear throughout the text where relevant to help you visualize internal anatomic features that can only be revealed through these diagnostic methods. Comprehensive list of tables and figures makes it easy to find key images and information at a glance. Detailed descriptions of anatomical structures ensure the most thorough, precise canine dissections. Clear and easy-to-follow instructions guide you in properly performing dissection techniques. Option of a digital book on Pageburst offers high-resolution illustrations that are directly linked to the text - letting you search for any text work or anatomic clue and discover any instance of what you want to read more about. NEW! High-resolution digital images have been added throughout the book to provide a clinical context for the drawings and to highlight internal anatomic structures with excellent contrast resolution. NEW! Additional transverse sections of the brain give you the anatomic knowledge you need to accurately interpret MR images. NEW! Updated figure labels and text adhere to the latest Nomina Anatomica Veterinaria.

Howard Evans was a brilliant ethologist and systematist for whom the joy of science included lying on his belly in some remote location, digging out and diagramming a wasp's nest. During his career, Evans described over 900 species and authored more than a dozen books, both technical and popular, on a wide range of entomological and natural history subjects. Upon his death in 2002, he left behind an unfinished manuscript, intended as an update (though not a revision) of his classic 1966 work, "The Comparative Ethology and Evolution of the Sand Wasps," Kevin O'Neill, Evans's former student and coauthor, has completed and enlarged Evans's manuscript, to provide coverage of all sand-wasp tribes in Evan's earlier book. The result is a tribe-by-tribe, species by species review of studies of the Bembicinae that have appeared over the last four decades. "The Sand Wasps: Natural History and Behavior" already has been hailed by specialists as a new bible for those working on solitary wasps and an essential reference for scientists more broadly interested in insect behavioral evolution.
