Book Description
This text summarizes the results of studies on the pollination ecology of the unique family Compositae (Asteraceae). The complex structural and functional specializations of the capitulum (or head) for pollinator attraction and pollen transfer are described in detail. An attempt is made to identify the influence of these specializations on the development and the function of other floral parts. The remarkable sex polymorphism of the Compositae head, which has caused much confusion amongst students is traced to this influence and characterized as a secondary modification. The central concept in the book is taht pollination ecology is the guiding factor in Compositae evolution.

Book Description
This volume highlights the new synthesis of pollination biology and plant mating systems which is rejuvenating the two-hundred-year-old discipline of floral biology. It provides a current examination of the evolution and functional significance of floral traits in animal-pollinated plants, combining ecological and genetic studies with natural history approaches and theoretical modeling. Divided into three sections, the book begins with the first English translation of Christian Konrad. Sprengel's introduction to his classic work and a historical analysis of his observations. The second section addresses current conceptual problems in floral biology, concentrating on floral diversification, floral longevity, pollen dispersal and mating patterns, the ecology of geitonogamous pollination, and flower size dimorphism in plants with unisexual flowers. The final chapters of the book examine model systems and include the evolution of floral morphology and function, deceit pollination, reproductive success and gender variation, stylar polymorphisms, and the evolution of flowers in relation to insect pollinators on islands. With its a detailed treatment of the selective forces shaping floral diversification in animal-pollinated plants, Floral Biology provides ecologists, evolutionary biologists, and botanists with a wealth of current information. Everyone interested in the evolution of flowering plants will benefit from this timely, authoritative resource on the interactions between insects and plants.

Book Description
Important breakthroughs have recently been made in our understanding of the cognitive and sensory abilities of pollinators: how pollinators perceive, memorise and react to floral signals and rewards; how they work flowers, move among inflorescences and transport pollen. These new findings have obvious implications for the evolution of floral display and diversity, but most existing publications are scattered across a wide range of journals in very different research traditions. This book brings together for the first time outstanding scholars from many different fields of pollination biology, integrating the work of neuroethologists and evolutionary ecologists to present a multi-disciplinary approach. Aimed at graduates and researchers of behavioural and pollination ecology, plant evolutionary biology and neuroethology, it will also be a useful source of information for anyone interested in a modern view of cognitive and sensory ecology, pollination and floral evolution.

Book Description
Secondary pollen presentation is presentation of pollen to vectors by structures other than anthers, either passively or via a specialized protection and delivery system. The main part of the book describes secondary pollen presentation genus-by-genus in 25 families. The subject has never been extensively reviewed, although secondary pollen presentation occurs in the largest family of flowering plants, the Asteraceae (Compositae), and a large family of great economic importance, the Leguminosae. Now material from the scattered literature is brought together and supplemented with original observations. Many species are illustrated and each family is individually discussed. The last two chapters provide an overview of the whole topic. All the main functions that secondary pollen presentation may perform can be carried out in other plants without it. It is concluded from this that the evolution of secondary pollen presentation has been subject to constraint and canalization. The floral biology of most plants with secondary pollen presentation has not been adequately studied. Appendix 1 points to a wide range of topics on which research at various technical and academic levels is needed. The book should also become a reference work for morphologists, systematists, and floral ecologists.

Book Description
A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.
