Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.

Spiders are often underestimated as suitable behavioural models because of the general belief that due to their small brains their behaviour is innate and mostly invariable. Challenging this assumption, this fascinating book shows that rather than having a limited behavioural repertoire, spiders show surprising cognitive abilities, changing their behaviour to suit their situational needs. The team of authors unravels the considerable intra-specific as well as intra-individual variability and plasticity in different behaviours ranging from foraging and web building to communication and courtship. An introductory chapter on spider biology, systematics and evolution provides the reader with the necessary background information to understand the discussed behaviours and helps to place them into an evolutionary context. Highlighting an under-explored area of behaviour, this book will provide new ideas for behavioural researchers and students unfamiliar with spiders as well as a valuable resource for those already working in this intriguing field.

With around 11 distinctive lineages and over 38,000 species of spiders alone, arachnids are an amazingly diverse group of invertebrates—and with names like the Goliath Bird-Eating Spider, the Tailless Whip Spider, and the Harvestman, they can be both spectacular and captivating. Most books about arachnids focus on spiders, neglecting scorpions, ticks, mites, wind spiders, and other fascinating yet poorly understood groups. This adventurous volume summarizes all existing knowledge about each major type of arachnid, revealing their secrets through detailed species accounts, brilliant photographs, and a compelling cast of eight-legged characters. It examines the anatomy, habitat, behavior and distribution of each lineage, from the garden spider to the death stalker scorpion and even a species of mite that lives inside a monkey's lungs. Drawing on the vast resources at London's Natural History Museum, Arachnids spins a sensational tale, debunking common myths and delving deep into the lives of these bizarre and beautiful creatures.
