Flowers on the Tree of Life

Flowers on the Tree of Life PDF Author: Livia Wanntorp
Publisher: Cambridge University Press
ISBN: 1139502352
Category : Science
Languages : en
Pages : 327

Book Description
Genetic and molecular studies have recently come to dominate botanical research at the expense of more traditional morphological approaches. This broad introduction to modern flower systematics demonstrates the great potential that floral morphology has to complement molecular data in phylogenetic and evolutionary investigations. Contributions from experts in floral morphology and evolution take the reader through examples of how flowers have diversified in a large variety of lineages of extant and fossil flowering plants. They explore angiosperm origins and the early evolution of flowers and analyse the significance of morphological characters for phylogenetic reconstructions on the tree of life. The importance of integrating morphology into modern botanical research is highlighted through case studies exploring specific plant groups where morphological investigations are having a major impact. Examples include the clarification of phylogenetic relationships and understanding the significance and evolution of specific floral characters, such as pollination mechanisms and stamen and carpel numbers.

Ecology and Evolution of Flowers

Ecology and Evolution of Flowers PDF Author: Lawrence D. Harder
Publisher: OUP Oxford
ISBN: 0191513865
Category : Science
Languages : en
Pages : 400

Book Description
The reproductive organs and mating biology of angiosperms exhibit greater variety than those of any other group of organisms. Flowers and inflorescences are also the most diverse structures produced by angiosperms, and floral traits provide some of the most compelling examples of evolution by natural selection. Given that flowering plants include roughly 250,000 species, their reproductive diversity will not be explained easily by continued accumulation of case studies of individual species. Instead a more strategic approach is now required, which seeks to identify general principles concerning the role of ecological function in the evolution of reproductive diversity. The Ecology and Evolution of Flowers uses this approach to expose new insights into the functional basis of floral diversity, and presents the very latest theoretical and empirical research on floral evolution. Floral biology is a dynamic and growing area and this book, written by the leading internationally recognized researchers in this field, reviews current progress in understanding the evolution and function of flowers. Chapters contain both new research findings and synthesis. Major sections in turn examine functional aspects of floral traits and sexual systems, the ecological influences on reproductive adaptation, and the role of floral biology in angiosperm diversification. Overall, this integrated treatment illustrates the role of floral function and evolution in the generation of angiosperm biodiversity. This advanced textbook is suitable for graduate level students taking courses in plant ecology, evolution, systematics, biodiversity and conservation. It will also be of interest and use to a broader audience of plant scientists seeking an authoritative overview of recent advances in floral biology.

Understanding Flowers and Flowering Second Edition

Understanding Flowers and Flowering Second Edition PDF Author: Beverley Glover
Publisher:
ISBN: 019966160X
Category : Gardening
Languages : en
Pages : 316

Book Description
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 (looking at the selective pressures placed on plants by pollinators, and the consequences for animal-plant co-evolution). Understanding Flowers and Flowering, the first edition of which won BES Marsh Book of the Year in 2009, begins by considering the evolution of flowers and the history of research into their development. This is followed by a detailed description of the processes which lead to flower production in model plants. The book then examines how flowers differ in shape, structure and colour, and how these differences are generated. Finally it assesses the role of these various aspects of floral biology in attracting pollinators and ensuring successful reproduction. This new edition has been completely revised and updated to reflect the latest advances in the field, especially an increased understanding of the evolution of floral traits. New chapters consider the genetic basis of the floral transition in diverse species, as well as the evolutionary lability of floral form. There is a new focus throughout on both phylogenetic position and morphological diversity across the angiosperm phylogeny. Understanding Flowers and Flowering continues to provide the first truly integrated study of the topic - one that discusses both the how and why of flowering plant reproductive biology.

Asymmetry in Plants

Asymmetry in Plants PDF Author: Bir Bahadur
Publisher: CRC Press
ISBN: 0429960700
Category : Nature
Languages : en
Pages : 370

Book Description
Plants exhibit forms of asymmetry analogous to "handedness" in bilaterally symmetrical animals. This book explores the evolutionary significance and development of asymmetry. Examples of genetic control include the direction of tendril or stem coiling of many climbing plants; the so-called spiral phyllotaxy and floral taxy; and contorted petal arrangement is another kind of left- right symmetry in plants; the direction of contortion is fixed in some but not in other plants. The book will underscore tha all phenomena related to handedness start during embryogenesis itself, with the occurrence of embryo rotation. Key selling features: First consolidated book on Plant Handedness Relates handedness, asymmetry and chirality to the evolution of different organizational levels in plant biology Emphasizes handedness as a vital governing force in plant functional evolution Provides a new perspective, hitherto ignored, into plant developemtn and evolution Describes how an age-old phenomenon can give scope for investigation from a very modern interdisciplinary approach

Annual Plant Reviews, Flowering and its Manipulation

Annual Plant Reviews, Flowering and its Manipulation PDF Author: Charles Ainsworth
Publisher: John Wiley & Sons
ISBN: 1405172401
Category : Science
Languages : en
Pages : 320

Book Description
The flowering plants now dominate the terrestrial ecosystems of theplanet, and there are good reasons for supposing that the floweritself has been a major contributing factor to the spread of theAngiosperms. The flowers of higher plants not only contain theorgans of plant reproduction but are of fundamental importance ingiving rise to fruits and seeds which constitute a major componentof the human diet. This volume opens with a chapter describing a model for theevolution of the Angiosperm flower. Chapters 2 to 5 describe thecore development of the flower and include floral induction, floralpattering and organ initiation, floral shape and size, andinflorescence architecture. Chapters 6 to 8 focus on morespecialised aspects of floral development: monoecy, cytoplasmicmale sterility and flowering in perennials. Chapters 9 and 10address more functional aspects: flower colour and scent. The bookconcludes, appropriately, with a chapter on flowersenescence. Applied aspects are stressed wherever appropriate, and the book isdirected at researchers and professionals in plant genetics,developmental and molecular biology. The volume has been designed to complement an earlier volume in ourAnnual Plant Reviews series, O'Neill, S. D. and Roberts, J. A.(2002) Plant Reproduction.

Advances in Insect Chemical Ecology

Advances in Insect Chemical Ecology PDF Author: Ring T. Cardé
Publisher: Cambridge University Press
ISBN: 9781139453257
Category : Science
Languages : en
Pages : 358

Book Description
Chemical signals mediate all aspects of insects' lives and their ecological interactions. The discipline of chemical ecology seeks to unravel these interactions by identifying and defining the chemicals involved, and documenting how perception of these chemical mediators modifies behaviour and ultimately reproductive success. Chapters in this 2004 volume consider how plants use chemicals to defend themselves from insect herbivores; the complexity of floral odors that mediate insect pollination; tritrophic interactions of plants, herbivores, and parasitoids and the chemical cues that parasitoids use to find their herbivore hosts; the semiochemically mediated behaviours of mites; pheromone communication in spiders and cockroaches; the ecological dependency of tiger moths on the chemistry of their host-plants; and the selective forces that shape the pheromone communication channel of moths. The volume presents descriptions of the chemicals involved, the effects of semiochemically mediated interactions on reproductive success, and the evolutionary pathways that have shaped the chemical ecology of arthropods.
