Flowers are the beautiful and complex reproductive structures of the angiosperms, one of the most diverse and successful groups of living organisms. The underlying thesis of this book is that to fully understand plant development (and why flowers differ in shape, structure and colour), it is necessary to understand why it is advantageous for them to look like they do. Conversely, in order to fully understand plant ecology, it is necessary to appreciate how floral structures have developed and evolved. Uniquely, this book addresses flowers and flowering from both a molecular genetic perspective (considering flower induction, development and self-incompatibility) and an ecological perspective ...
Most of us are aware of the hive mind-the power of bees as an amazing collective. But do we know how uniquely intelligent bees are as individuals? In The Mind of a Bee, Lars Chittka draws from decades of research, including his own pioneering work, to argue that bees have remarkable cognitive abilities.
Evolution, induction of flowering, variation.
Leaves are all around us—in backyards, cascading from window boxes, even emerging from small cracks in city sidewalks given the slightest glint of sunlight. Perhaps because they are everywhere, it’s easy to overlook the humble leaf, but a close look at them provides one of the most enjoyable ways to connect with the natural world. A lush, incredibly informative tribute to the leaf, Nature’s Fabric offers an introduction to the science of leaves, weaving biology and chemistry with the history of the deep connection we feel with all things growing and green. Leaves come in a staggering variety of textures and shapes: they can be smooth or rough, their edges smooth, lobed, or with tiny te...

The Meaning of Success: Insights from Women at Cambridge makes a compelling case for a more inclusive definition of success. It argues that in order to recognise, reward and realise the talents of both women and men, a more meaningful definition of success is needed. Practical ways of achieving this are explored through interviews with female role models at the University of Cambridge. First-person stories bring alive the achievements and challenges women experience in their working lives, and the effect gender has on careers. The book stimulates a debate about how to bring about a more inclusive working environment.
The triumphs of recent biology - understanding hereditary disease, the modern theory of evolution - are all thanks to the fruit fly, the guinea pig, the zebra fish and a handful of other organisms, which have helped us unravel one of life's greatest mysteries - inheritance. Jim Endersby traces his story from Darwin hand-pollinating passion flowers in his back garden in an effort to find out whether his decision to marry his cousin had harmed their children, to today's high-tech laboratories, full of shoals of shimmering zebra fish, whose bodies are transparent until they are mature, allowing scientists to watch every step as a single fertilised cell multiples to become millions of specialised cells that make up a new fish. Each story has - piece by piece - revealed how DNA determines the characteristics of the adult organism. Not every organism was as cooperative as the fruit fly or zebra fish, some provided scientists with misleading answers or encouraged them to ask the wrong questions.

The voluntary sector contains over 50,000 organizations, 320,000 paid staff, and 3 million volunteers. The accounting and financial management of organizations in this sector poses as many difficulties as that of major for-profit organizations, if not more so, given the absence of the profit motive upon which much traditional accounting, finance practice and theory has been developed. This book explores the unique environmental, managerial and philosophical aspects of voluntary organizations as well as the technical specialist characteristics of financial accounting, auditing and taxation that differentiate their role. Introducing and providing descriptions of the main applications of accounting and finance applicable to the role of financial manager, this book uses real life case studies and examines the debates presented by other writers in the field. This key book helps readers make their own critical judgements, and contributes to their understanding of the distinctiveness of voluntary sector accounting and financial management.
