Book Description
Gender was a fluid potential, not a fixed category, before the Spaniards came to Mesoamerica. Childhood training and ritual shaped, but did not set, adult gender, which could encompass third genders and alternative sexualities as well as "male" and "female." At the height of the Classic period, Maya rulers presented themselves as embodying the entire range of gender possibilities, from male through female, by wearing blended costumes and playing male and female roles in state ceremonies. This landmark book offers the first comprehensive description and analysis of gender and power relations in prehispanic Mesoamerica from the Formative Period Olmec world (ca. 1500-500 BC) through the Postclassic Maya and Aztec societies of the sixteenth century AD. Using approaches from contemporary gender theory, Rosemary Joyce explores how Mesoamericans created human images to represent idealized notions of what it meant to be male and female and to depict proper gender roles. She then juxtaposes these images with archaeological evidence from burials, house sites, and body ornaments, which reveals that real gender roles were more fluid and variable than the stereotyped images suggest.

Book Description
The ocean covers 70 percent of the Earth’s surface, and is essential for life on our planet – even for those of us who live nowhere near the sea! It provides us all with food and other materials that we need, regulates our climate and provides half of the oxygen we breathe. The ocean also offers us various means of transport and opportunities for recreation. People have long thought that the ocean was so wide and bountiful that it would go on supplying our needs forever, but this is not the case: human activities are causing significant damage to life in the ocean. People are often unaware of the problems created by this heavy reliance, as few of us have the opportunity to look beneath the surface of the sea and see the damage that our actions have caused. This is where the Ocean Challenge Badge comes in: let it take you on a journey to discover the ocean! It is packed with activities to help you learn about how the ocean works, the creatures that live in it, and just how important it is in our everyday lives. You will also discover how YOU can play a role in protecting our ocean for future generations. We hope you will be inspired to take the challenge and celebrate our ocean. So dive in and begin your aquatic discoveries!

Book Description
Animal fibres from South American camelids and other fibre or wool bearing species provide important products for use by the human population. The contemporary context includes the competition with petrocarbon-based artificial fibres and concern about excessive persistence of these in the natural environment. Animal fibres present highly valuable characteristics for sustainable production and processing as they are both natural and renewable. On the other hand, their use is recognised to depend on availability of appropriate quality and quantity, the production of which is underpinned by a range of sciences and processes which support development to meet market requirements. This collection of papers combines international experience from South and North America, China and Europe. The focus lies on domestic South American camelids (alpacas, llamas) and also includes research on sheep and goats. It considers latest advances in sustainable development under climate change, breeding and genetics, reproduction and pathology, nutrition, meat and fibre production and fibre metrology. Publication of this book is supported by the Animal Fibre Working Group of the European Federation of Animal Science (EAAP). ‘Advances in Fibre Production Science in South American Camelids and other Fibre Animals’ addresses issues of importance to scientists and animal breeders, textile processors and manufacturers, specialised governmental policy makers and students studying veterinary, animal and applied biological sciences.
