A simpler and more user-friendly visual approach to gull identification
This unique photographic field guide to North America's gulls provides a comparative approach to identification that concentrates on the size, structure, and basic plumage features of gulls--gone are the often-confusing array of plumage details found in traditional guides.
Featuring hundreds of color photos throughout, Gulls Simplified illustrates the variations of gull plumages for a variety of ages, giving readers strong visual reference points for each species. Extensive captions accompany the photos, which include comparative photo arrays, digitized photo arrays for each age group, and numerous images of each species--a wealth of visual information at your fingertips. This one-of-a-kind guide includes detailed species accounts and a distribution map for each gull.

Описание: First published in 1992, this guide has been significantly expanded in a new 3rd edition. The popular, user-friendly field guide, covering all major groups of marine invertebrates encountered by divers on coral reefs and adjacent habitats, has grown to include 900 species beautifully documented with more than 1200 underwater photographs -- nearly doubling the total in the previous editions. Les Wilk has joined Paul Humann and Ned DeLoach authoring the comprehensive new edition.
Описание: "A must-have for anyone involved with mosquitoes. This is the only key that incorporates the recent changes in nomenclature and new species listings with their respective distribution."--Dennis Moore, director, Pasco County Mosquito Control District Greatly anticipated and sorely needed, this book updates the successful guide to North American mosquitoes published by the American Mosquito Control Association in 1981. It includes 12 new species that have since been added to the North American mosquito fauna, revised distribution maps of all species, and revised and completely illustrated identification keys for the adult females and fourth instar larvae of all 174 species and subspecies known to occur in North America, north of Mexico. In chapters on adult and larval morphology, the coauthors--both world-renowned in their field of taxonomy--discuss the anatomical structures mentioned in the keys and pictured on full-page plates. They provide separate generic keys for adult females and larvae and keys to the species of each genus. In addition, they show the geographical distribution of each taxon in a series of maps and include a synopsis of the occurrence of species in the states and provinces of the United States and Canada. This book's usefulness to mosquito control programs cannot be overestimated. For example, it deals with 9 exotic species that have been introduced and today successfully thrive in North America. Several are increasing their range and this book will help identify these species when they first invade an area. Because of the occurrence of mosquito-borne diseases and the widespread distribution of mosquitoes as pests to humans, professionals must know how to identify them. With its wealth of up-to-date information, this book is the only one of its kind available for specialists working on mosquito-borne diseases and in mosquito control units and for both introductory and advanced students who study entomology. Richard F. Darsie Jr. is a research entomologist at the Florida Medical Entomology Laboratory at the University of Florida. Ronald A. Ward was a medical entomologist at the Walter Reed Army Institute of Research in Washington, D.C., before his retirement.
The Biology and Identification of the Coccidia (Apicomplexa) of Marsupials of the World contains the most up-to-date information on the former order marsupial that is now partitioned by mammalogists into seven separate orders that contain 20 families, 86 genera, and 318 species that live on land or in trees in Oceania and the Americas.
Marsupials, like other vertebrate animals have many different kinds of parasites (e.g. viruses, protozoa, worms, arthropods, etc.), but there is no definitive text that covers any one of these groups found in all marsupials.
Coccidiosis is a serious global problem in most domesticated animals, and under increasing circumstances of loss of habitat and crowding, may also affect some wild animal populations, thus, there is a real need for their identification and control.

The 25th Anniversary 4th Edition reflects the many recent changes including 89 new fish species and more than 200 additional photographs. The field guide now includes 683 species documented in more than 1000 underwater photographs, representing a significant update to the 2002 3rd edition. The most comprehensive and beautiful visual ID reference published for the region features an easy-to-use quick reference format. Reef Fish Identification Florida Caribbean Bahamas first appeared in 1989 and has since revolutionized fishwatching. The first edition had 288 pages and 345 color photographs.
