The astounding breadth of diversity of life on earth intrigues and amazes many people, while the future of world biodiversity is a cause for widespread concern. Within the current context of global interest in biological diversity, this is a timely review of the most recent research into the evolutionary origins of biological diversity and the processes of speciation, from a stellar cast of contributors. Recent studies have discovered considerable genetic and morphological variation both between and within populations of the same species. Yet the relation between this intraspecific variation and the processes of speciation remains poorly understood. When, how, and why do new species arise? The chapters in this book explore the question of how variation arises within species; some emphasize the ecological and behavioural basis of differentiation; others argue for the role of natural selection in generating speciation. Several chapters focus on the important emerging links between sexual selection, sexual conflict, and population differentiation. The final chapters of the book take a broader perspective on the question, and explore the fossil record for data on the origination of species diversity - and extinctions - in the past. This book is a must-have for all researchers and graduate students in the biological sciences who want to be abreast of the latest thinking on the evolution of biological diversity.

Universal Design for Web Applications teaches you how to build websites that are more accessible to people with disabilities and explains why doing so is good business. It takes more work up front, but the potential payoff is huge -- especially when mobile users need to access your sites.You''ll discover how to use standards-based web technologies -- such as XHTML, CSS, and Ajax, along with video and Flash -- to develop applications for a wide range of users and a variety of devices, including the mobile Web. You''ll also learn specifics about this target audience, especially the key over-50 age group, whose use of the Web is rapidly growing.With this book, you will:

Learn the importance of metadata and how it affects images, headings, and other design elementsBuild forms that accommodate cell phones, screen readers, word prediction, and moreCreate designs using color and text that are effective in a variety of situationsConstruct tables that present information without spatial cuesDesign Ajax-driven social networking applications that people with disabilities can accessProvide audio with transcriptions and video that includes captions and audio descriptionsDiscover assistive technology support for Rich Internet Application technologies such as Flash, Flex, and Silverlight

Universal Design for Web Applications provides you with a roadmap to help you design easy-to-maintain web applications that benefit a larger audience.
