Diversity Phylogeny And Evolution In The Monocotyledons

"Monocotyledons ('monocots'), though comprising only one fourth of all flowering plant species, are economically and ecologically crucial. In families such as the grasses and palms, they include some of the most valuable plant species to humanity. Numerous monocot species have great ornamental value due to their spectacular flowers or characteristic structural features. They range in size from the smallest flowering plants, Wolffia arrbiza, little more than 1 mm across, to massive palm trees up to 40 m tall. Monocot species occur in arctic regions, wet tropical forests, and deserts, and have a wide range of life forms, including floating and rooted aquatic plants, geophytes, epiphytes, and lianas. Diversity, Phylogeny, and Evolution in the Monocotyledons includes reviews and reports of current research by the world's leading specialists, based on presentations made at the Fourth International Conference on the Comparative Biology of the Monocotyledons and the Fifth International Symposium on Grass Systematics and Evolution, held in Copenhagen in 2008."--Publisher's description.

Monocots: Systematics and Evolution presents leading work from around the world on non-grass monocotyledons and includes reviews and current research into their comparative biology, phylogeny and classification. The papers are based on presentations at the Second International Conference on the Comparative Biology of the Monocotyledons, Monocots II, held in Sydney, Australia in late 1998. Many were subsequently updated or extended to take into account new information. All 72 papers have been peer-reviewed.

The fifth international conference on the comparative biology of Monocotyledons (Monocots V) convened in New York City in June 2013, marking the 20th anniversary of the conference series. The New York botanical garden (Bronx) hosted Monocots V, also using facilities of the adjacent, beautiful fordham university Rose Hill campus. Over 330 participants, including about 80 students, represented 37 countries. Twenty-two symposia covered a wide array of taxonomic groups and subjects, such as life history strategies, morphology, paleobiology, phylogenomics, and reproductive biology. This volume of proceedings from Monocots V comprises 12 papers from 24 contributing authors. Monocot groups represented include Asparagales, Pandanales, Poales, Commelinaceae, and Hydrocharitaceae. Among the volume's dozen papers is the Conference's plenary lecture by Paula J. Rudall (Royal botanic gardens, Kew), "Morphological misfits and character evolution in monocots, with particular reference to Pandanales.

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.

Leading scientists in the field trace the evolution of the one of the most ancient major branches of flowering plants.

To some extent classification is subjective. Taxonomists differ in the relative importance they ascribe to particular characters and in the degree of difference between related taxa they deem sufficient to constitute family or ordinal rank. About 250 monocot family names have been published. Those who have attempted an overview of the system at the family level and above in the last quarter century recognize between 45 and 103 monocot families in 14 to 38 orders. I accept 57 families in 18 orders. In Table 1 I give my ordinal allocation of the families and that of 11 recent authors to indicate where there is agreement and where there are differences to be resolved. I have constructed a dendrogram to suggest relationships and degree of advancement of the orders.I have written concise, uniform descriptions of all the families of monocots emphasizing those characters that show trends between families or occur in more than one family. Each family is illustrated by analytical drawings of the flower, fruit, seed, and usually inflorescence. Several species are usually used to show the range of major variation within families and trends toward related families.

Diversity and Evolution of Land Plants provides a fresh and long overdue treatment of plant anatomy and morphology for the biology undergraduate of today. Setting aside the traditional plod through the plant taxa, the author adopts a problem-based functional approach, exploring plant diversity as a series of different solutions to the design problems facing plant life on land.

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.
