Book Description
• First title in Stackpole Books' new Wild Guide series • A complete, expert introduction to the world of dragonflies and also covers damselflies • Detailed color drawings of different species and behaviors Dazzling in appearance, idiosyncratic in behavior, dragonflies and damselflies have long captured the imaginations of nature lovers. In this illustrated natural history guide, Cynthia Berger takes the reader on a whirlwind trip through the lives of these intriguing insects, from their birth underwater (where they actually spend most of their lives as ferocious nymphs) to their miraculous transformation into free-flying adults. Features a field guide to the most common North American species--including life-size silhouettes for easy identification--as well as tips for observing dragonflies in the wild and attracting them to your backyard.

Book Description
This timely book revisits cryptic female choice in arthropods, gathering detailed contributions from around the world to address key behavioral, ecological and evolutionary questions. The reader will find a critical summary of major breakthroughs in taxon-oriented chapters that offer many new perspectives and cases to explore and in many cases unpublished data. Many groups of arthropods such as spiders, harvestmen, flies, moths, crickets, earwigs, beetles, eusocial insects, shrimp and crabs are discussed. Sexual selection is currently the focus of numerous and controversial theoretical and experimental studies. Selection in mating and post-mating patterns can be shaped by several different mechanisms, including sperm competition, extreme sexual conflict and cryptic female choice. Discrimination among males during or after copulation is called cryptic female choice because it occurs after intromission, the event that was formerly used as the definitive criterion of male reproductive success and is therefore usually difficult to detect and confirm. Because it sequentially follows intra- and intersexual interactions that occur before copulation, cryptic female choice has the power to alter or negate precopulatory sexual selection. However, though female roles in biasing male paternity after copulation have been proposed for a number of species distributed in many animal groups, cryptic female choice continues to be often underestimated. Furthermore, in recent years the concept of sexual conflict has been frequently misused, linking sexual selection by female choice irrevocably and exclusively with sexually antagonistic co-evolution, without exploring other alternatives. The book offers an essential source of information on how two fields, selective cooperation and individual sex interests, work together in the context of cryptic female choice in nature, using arthropods as model organisms. It is bound to spark valuable discussions among scientists working in evolutionary biology across the world, motivating new generations to unveil the astonishing secrets of sexual biology throughout the animal kingdom.

Book Description
In most terrestrial and aquatic habitats, the vast majority of animals transmitting and receiving communicative signals are arthropods. This book presents the story of how this important group of animals use pheromones, sound, vibration, and light for sexual and social communication. Because of their small to minute body size most arthropods have problems sending and receiving acoustic and optical information, each of which have their own severe constraints. Because of these restraints they have developed chemical signaling which is not similarly limited by scale. Presenting the latest theoretical and experimental findings from studies of signaling, it suggests that close parallels between arthropods and vertebrates reflect a very limited number of solutions to problems in behavior that are available within the confines of physical laws.

Book Description
An accessible introduction to climate change that outlines key scientific, economic, and political issues, reviews how the global community has addressed the issue to date, and discusses the options being explored for further action. Climate Change: A Reference Handbook offers readers a way to separate science from politics on this crucial and often contentious issue. It provides a comprehensive introduction to the science and public policy of climate change, including discussion of historical developments, today's key concepts, and the future of climate science and policy. Climate Change begins by explaining the science behind global climate change, including the growing consensus that human activity is a major contributing factor. It then takes an objective look at the key conflicts in climate science and policy, describes those that have been resolved, and offers a balanced review of proposals for those that have not. A separate chapter focuses on the scientific, economic, and political aspects of climate change as they are playing out specifically in the United States.

Book Description
Winner of the Single Volume Reference/Science award of the Professional and Scholarly Publishing Awards given by the Association of American Publishers Dragonfly Genera of the New World is a beautifully illustrated and comprehensive guide to the taxonomy and ecology of dragonflies in North, Middle, and South America. A reference of the highest quality, this book reveals the striking beauty and complexity of this diverse order. Although Odonata—dragonflies and damselflies—are among the most studied groups of insects, until now there has been no reliable means to identify the New World genera of either group. This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia. For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.
