Tracing the evolution of one of the most ancient major branches of flowering plants, this is a wide-ranging survey of state-of-the-art research on the early clades of the monocot phylogenetic tree. It explores a series of broad but linked themes, providing for the first time a detailed and coherent view of the taxa of the early monocot lineages, how they diversified and their importance in monocots as a whole. Featuring contributions from leaders in the field, the chapters trace the evolution of the monocots from largely aquatic ancestors. Topics covered include the rapidly advancing field of monocot fossils, aquatic adaptations in pollen and anther structure and pollination strategies and floral developmental morphology. The book also presents a new plastid sequence analysis of early monocots and a review of monocot phylogeny as a whole, placing in an evolutionary context a plant group of major ecological, economic and horticultural importance.

Aquatic Monocotyledons of North America brings together information on the natural history, ecology and systematics of North American aquatic monocotyledons. The book is an overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference sources. Information on more than 300 species in 87 genera of monocotyledons will be included. Recent phylogenetic analyses will be incorporated. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well.

Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Phylogenetics emerged in the second half of the nineteenth century as a speculative storytelling discipline dedicated to providing narrative explanations for the evolution of taxa and their traits. It coincided with lineage thinking, a process that mentally traces character evolution along lineages of hypothetical ancestors. Ancestors in Evolutionary Biology traces the history of narrative phylogenetics and lineage thinking to the present day, drawing on perspectives from the history of science, philosophy of science, and contemporary scientific debates. It shows how the power of phylogenetic hypotheses to explain evolution resides in the precursor traits of hypothetical ancestors. This book provides a comprehensive exploration of the topic of ancestors, which is central to modern biology, and is therefore of interest to graduate students, researchers, and academics in evolutionary biology, palaeontology, philosophy of science, and the history of science.

Charles Darwin, the father of the theory of evolution, described the evolutionary origin of flowering plants, which appear to have risen abruptly during the late Cretaceous Period, as an "abominable mystery." The first seed plants appeared in the fossil record some 230 million years earlier, but the transitions leading to the flowering plants left few fossils and remain obscure. The evolutionary history of photosynthetic organisms is full of mysteries great and small, including the origin of photosynthesis itself, the origins of multiple independent lines of algae, the loss of flagella in the red algae, the origin of sporophytes in vascular and non-vascular plants, the early diversification of seed plants, and the origin of the unique monocots. In Plant Life: A Brief History, botanist Frederick Essig traces how familiar features of plants evolved sequentially over hundreds of millions of years as various environmental challenges and opportunities were met. This chronological narrative begins with the origin of photosynthesis and the rise of cyanobacteria, continues with the evolution and diversification of photosynthetic eukaryotes and their invasion of dry land, explores the varied adaptations for sexual reproduction and dispersal in the terrestrial environment, and concludes with the diverse growth forms of the flowering plants. As different groups of photosynthetic organisms are introduced, the book emphasizes the adaptations that enabled them to gain dominance in existing habitats or move into new habitats. Readers will acquire a deeper understanding of the diverse photosynthetic organisms humans depend upon for food, oxygen, medicine, building materials, and aesthetic pleasure. With accessible writing and a myriad of figures and illustrations, Essig provides a broad overview of plant evolution that will appeal to students and general audiences alike. Plant Life: A Brief History is a valiant step in the quest to unravel the "abominable mysteries" of plant evolution, and offers a compelling introduction to the exciting and complex world of evolutionary biology.

Seagrasses Of Australia written by Anthony W. D. Larkum and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2018-07-27 with Science categories.

This book takes the place of “Biology of Seagrasses: A Treatise on the Biology of Seagrasses with Special Reference to the Australian Region”, co-edited by A.W.D. Larkum, A.J. MaCComb and S.A. Shepherd and published by Elsevier in 1989. The first book has been influential, but it is now 25 years since it was published and seagrass studies have progressed and developed considerably since then. The design of the current book follows in the steps of the first book. There are chapters on taxonomy, floral biology, biogeography and regional studies. The regional studies emphasize the importance of Australia having over half of the world’s 62 species, including some ten species published for Australia since the previous book. There are a number of chapters on ecology and biogeography; fish biology and fisheries and dugong biology are prominent chapters. Physiological aspects again play an important part, including new knowledge on the role of hydrogen sulphide in sediments and on photosynthetic processes. Climate change, pollution and environmental degradation this time gain an even more important part of the book. Decline of seagrasses around Australia are also discussed in detail in several chapters. Since the first book was published two new areas have received special attention: blue carbon and genomic studies. Seagrasses are now known to be a very important player in the formation of blue carbon, i.e. carbon that has a long turnover time in soils and sediments. Alongside salt marshes and mangroves, seagrasses are now recognized as playing a very important role in the formation of blue carbon. And because Australia has such an abundance and variety of seagrasses, their role in blue carbon production and turnover is of great importance. The first whole genomes of seagrasses are now available and Australia has played an important role here. It appears that seagrasses have several different suites of genes as compared with other (land) plants and even in comparison with freshwater hydrophytes. This difference is leading to important molecular biological studies where the new knowledge will be important to the understanding and conservation of seagrass ecosystems in Australia. Thus by reason of its natural abundance of diverse seagrasses and a sophisticated seagrass research community in Australia it is possible to produce a book which will be attractive to marine biologists, coastal scientists and conservationists from many countries around the world.
