This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

The honey bee waggle dance communication is a complex, unique, at times controversial, and ultimately fascinating behavior. In an elaborate figure-of-eight movement, a returning forager conveys the distance and direction from the hive to resources, usually the nectar and pollen that is their food, and it remains one of the most sophisticated, known forms of non-human communication. Not surprisingly, since its discovery more than 60 years ago by Karl von Frisch, the dance has been subject to investigations that span from basic biology through human culture and neurophysiology to landscape ecology. Here we aim to collate recent advances in our understanding of the dance, including (but not limited to) potential fitness benefits, the causes and consequences of error in the dance, neurobiological differences in how bees measure distance, the use by bees of different landscapes and its impact on pollination, and methodological advances that may not only improve our mapping of bee foraging ecology, but also in the basic understanding of the dance.

Les terres consacrées à l'élevage couvrent près de 4 millions d'hectares dans le monde, soit 80 % des surfaces agricoles et la demande en produits animaux est en hausse constante, notamment dans les pays tropicaux. D'une importance capitale dans le développement durable des régions chaudes, la production fourragère est le principal levier de la productivité des systèmes d'élevage. Elle joue également un rôle essentiel pour les systèmes qui allient productions végétales et animales et de nombreux systèmes agroécologiques intègrent des plantes fourragères. La première partie de cet ouvrage est destinée à guider le choix de plantes fourragères et de leurs cultures (diversités des plantes, des usages, des milieux et des types d'élevage). La seconde partie est consacrée aux techniques de culture, à la gestion des fourrages, à la valorisation des ligneux, à la production de semences et à l'économie de ces productions. L'ouvrage est accompagné d'un cédérom qui comprend des études de cas originales, des textes et des photos complémentaires, une bibliographie. Cet ouvrage de synthèse s'adresse aux éleveurs, agronomes, techniciens, professionnels des productions animales et fourragères.

At birdfeeders and in backyards across North America, the dark-eyed junco, or snowbird, can be found foraging for its next meal. With an estimated population of at least 630 million, juncos inhabit forests, parks, and even suburban habitats, making them one of the continent's most abundant and easily observable songbirds. But while common and widespread, juncos also exhibit extraordinary diversity in color, shape, size, and behavior across their range, making them ideal study subjects for biologists interested in ecology and evolutionary diversification. Intended for scholars, citizen scientists, and amateur ornithologists, alike, Snowbird synthesizes decades of research from the diverse and talented researchers who study the Junco genus. Though contributors approach their subject from a variety of perspectives, they share a common goal: elucidating the organismal and evolutionary processes by which animals adapt and diversify in response to environmental change. Placing special emphasis on the important role that underlying physiological, hormonal, and behavioral mechanisms play in these processes, Snowbird not only provides a definitive exploration of the junco's evolutionary history and behavioral and physiological diversity but also underscores the junco's continued importance as a model organism in a time of rapid global climate change. By merging often disparate biological fields, Snowbird offers biologists across disciplines an integrative framework for further research into adaptation, population divergence, and the formation of new species.

The Biology of Sharks and Rays is a comprehensive resource on the biological and physiological characteristics of the cartilaginous fishes: sharks, rays, and chimaeras. In sixteen chapters, organized by theme, A. Peter Klimley covers a broad spectrum of topics, including taxonomy, morphology, ecology, and physiology. For example, he explains the body design of sharks and why the ridged, toothlike denticles that cover their entire bodies are present on only part of the rays' bodies and are absent from those of chimaeras. Another chapter explores the anatomy of the jaws and the role of the muscles and teeth in jaw extension, seizure, and handling of prey. The chapters are richly illustrated with pictures of sharks, diagrams of sensory organs, drawings of the body postures of sharks during threat and reproductive displays, and maps showing the extent of the species' foraging range and long-distance migrations. Each chapter commences with an anecdote from the author about his own personal experience with the topic, followed by thought-provoking questions and a list of recommended readings in the scientific literature. The book will be a useful textbook for advanced ichthyology students as well as an encyclopedic source for those seeking a greater understanding of these fascinating creatures.
