A comprehensive two-volume set that displays the full diversity, evolutionary patterns and biological complexity of Arborescent Gymnosperms.This two-volume reference set, covering the Northern and Southern Hemispheres, provides a comprehensive description of the evolution and diversity of the arborescent gymnosperms, illustrated with distribution maps, form silhouettes and a wealth of colour plates. Invaluable to researchers in palaeobotany, geobiology and evolutionary biology.This two-volume reference set, covering the Northern and Southern Hemispheres, provides a comprehensive description of the evolution and diversity of the arborescent gymnosperms, illustrated with distribution maps, form silhouettes and a wealth of colour plates. Invaluable to researchers in palaeobotany, geobiology and evolutionary biology.The arborescent gymnosperms are the most prevalent trees in one-third of the world's forests, and have dominated the Earth's forest ecosystems through much of evolutionary time. They encompass over 70 living genera and nearly 700 species of evergreen conifers and related trees, and include the largest and longest-lived organisms on this planet. This two-volume treatise provides detailed descriptions of each genus based on first-hand surveys of their structure, adaption, ecology, function and development. It also incorporates evidence from molecular studies, palaeobotany and environmental data to provide a holistic understanding of their overall evolution and diversity. Covering the world's temperate and tropical forests, Volume 1 principally focuses on Northern Hemisphere genera while Volume 2 covers those with a predominantly Southern Hemisphere range. Together, the set provides a comprehensive, global reference for researchers in palaeobotany, plant science, geobiology, evolutionary biology, ecology and plant genetics, as well as arboriculturists and conservation managers.Preface and Acknowledgements; Structure of the Two Volumes; Part I.
