Book Description
Learn all about the world of spiders in this complete and comprehensive guide, filled with stunning facts, beautiful photography and diagrams to help you understand everything you ever needed to know about arachnids! Bark spiders spin webs ten times stronger than Kevlar. Jumping spiders are capable of learning, recognizing, and remembering colours. Recluse spiders can tolerate six months of extreme drought and have a toxin-laden bite that can necessitate skin grafts. These are just some of the many amazing facts which you will discover in Spiders of the World, the perfect guide to one of natures most fascinating and varied creatures. This title explores the huge diversity of spider species and their fascinating traits. An introduction outlining the spider’s natural history is followed by 117 illustrated profiles spanning the taxonomic spider families. Beautiful close-up photographs of species from each family are shown, along with population distribution maps, tables of essential information, and commentaries revealing notable characteristics. The family profiles are also organized phylogenetically, and the commentaries in each account reflect different aspects of a spider’s biology.

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major breakthroughs in taxon-oriented chapters that offer many new perspectives and cases to explore and in many cases unpublished data.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
Covering the contextual and taxonomic diversity of cannibalism, this book explains its costs, benefits, and consequences for a taxonomically broad distribution of species from lower eukaryotes to higher primates. The authors, all experts in their taxon of interest, use theory developed for the analysis of foraging, sociality, demography, and genetics to assess the ecological and evolutionary causes and effects of cannibalism. The emerging picture from recent research challenges the view that cannibalism is either abnormal behaviour or an infrequent addition to the predator's usual diet.

Book Description
Contests are an important aspect of the lives of diverse animals, from sea anemones competing for space on a rocky shore to fallow deer stags contending for access to females. Why do animals fight? What determines when fights stop and which contestant wins? Addressing fundamental questions on contest behaviour, this volume presents theoretical and empirical perspectives across a range of species. The historical development of contest research, the evolutionary theory of both dyadic and multiparty contests, and approaches to experimental design and data analysis are discussed in the first chapters. This is followed by reviews of research in key animal taxa, from the use of aerial displays and assessment rules in butterflies and the developmental biology of weapons in beetles, through to interstate warfare in humans. The final chapter considers future directions and applications of contest research, making this a comprehensive resource for both graduate students and researchers in the field.
