Flowering Plants. Monocotyledons

Flowering Plants. Monocotyledons PDF Author: Klaus Kubitzki
Publisher: Springer Science & Business Media
ISBN: 9783540640615
Category : Science
Languages : en
Pages : 532

Book Description
When Rolf Dahlgren and I embarked on preparing this book series, Rolf took prime responsibility for monocotyledons, which had interested him for a long time. After finishing his comparative study and family classification of the monocots, he devoted much energy to the acquisition and editing of family treatments for the present series. After his untimely death, Peter Goldblatt, who had worked with him, continued to handle further incoming monocot manuscripts until, in the early 1990s, his other obligations no longer allowed him to continue. At that time, some 30 manuscripts in various states of perfection had accumulated, which seemed to form a solid basis for a speedy completion of the FGVP monocots; with the exception of the grasses and orchids which would appear in separate volumes. I felt a strong obligation to do everything to help in publishing the manuscripts that had been put into our hands. I finally decided to take charge of them personally, although during my life as a botainst I had never seriously been interested in monocots.

Plants of the World

Plants of the World PDF Author: Maarten J. M. Christenhusz
Publisher: University of Chicago Press
ISBN: 022653670X
Category : Nature
Languages : en
Pages : 801

Book Description
Plants of the World is the first book to systematically explore every vascular plant family on earth—more than four hundred and fifty of them—organized in a modern phylogenetic order. Detailed entries for each family include descriptions, distribution, evolutionary relationships, and fascinating information on economic uses of plants and etymology of their names. All entries are also copiously illustrated in full color with more than 2,500 stunning photographs. A collaboration among three celebrated botanists at the Royal Botanic Gardens, Kew, Plants of the World is authoritative, comprehensive, and beautiful. Covering everything from ferns to angiosperms, it will be an essential resource for practicing botanists, horticulturists, and nascent green thumbs alike.

Polyploidy

Polyploidy PDF Author: Walter H. Lewis
Publisher: Springer Science & Business Media
ISBN: 1461330696
Category : Medical
Languages : en
Pages : 576

Book Description
Polyploidy as a dramatic mutational event in the process of evolution has wide implications in nature and for the generation of new and improved crops. The three day Conference on POLYPLOIDY: BIOLOGICAL RELEVANCE focused on three aspects of this natural phenomenon: the first emphasized the characteristics of polyploidy, the second described the occurrence of polyploidy among plants and animals, and the third considered past and future areas of both fundamental and pragmatic research that involve polyploidy. New information relative to origin, cytogenetics, ecology, physiology, biochemistry, and populational studies stress the need to reexamine current views on the origins of polyploidy and its significance among both plants and animals. There are major differences in the occurrence of polyploidy between. plant groups and it is proving a much more common event among bisexual vertebrates than heretofore considered possible. Crop development and improvement must utilize approaches based fundamentally on more natural systems; in fact future research should focus more on polyploidy as a natural phenomenon that needs study at all levels of endeavor from field-oriented populational aspects to sophisticated molecular analyses and genome manipulations. This volume provides a summary of current knowledge of polyploidy pertinent to botanists, zoologists, and agriculturists who are interested in the evolution o~natural systems and who are concerned with the contribution that crop improvement can make to human well-being. Walter H. Lewis St. Louis, Missouri October, 1979 v ACKNOWLEDGMENTS The Host Committee thanks all speakers and moderators for their generous contribution to the Conference and to this volume.

Ecology of Lianas

Ecology of Lianas PDF Author: Stefan Schnitzer
Publisher: John Wiley & Sons
ISBN: 1118392485
Category : Science
Languages : en
Pages : 517

Book Description
Lianas are woody vines that were the focus of intense study by early ecologists, such as Darwin, who devoted an entire book to the natural history of climbing plants. Over the past quarter century, there has been a resurgence in the study of lianas, and liana are again recognized as important components of many forests, particularly in the tropics. The increasing amount of research on lianas has resulted in a fundamentally deeper understanding of liana ecology, evolution, and life-history, as well as the myriad roles lianas play in forest dynamics and functioning. This book provides insight into the ecology and evolution of lianas, their anatomy, physiology, and natural history, their global abundance and distribution, and their wide-ranging effects on the myriad organisms that inhabit tropical and temperate forests.

Island Historical Ecology

Island Historical Ecology PDF Author: Peter E. Siegel
Publisher: Berghahn Books
ISBN: 1785337645
Category : Social Science
Languages : en
Pages : 449

Book Description
In the first book-length treatise on historical ecology of the West Indies, Island Historical Ecology addresses Caribbean island ecologies from the perspective of social and cultural interventions over approximately eight millennia of human occupations. Environmental coring carried out in carefully selected wetlands allowed for the reconstruction of pre-colonial and colonial landscapes on islands between Venezuela and Puerto Rico. Comparisons with well-documented patterns in the Mediterranean and Pacific islands place this case study into a larger context of island historical ecology.

Mobility and Migration in Indigenous Amazonia

Mobility and Migration in Indigenous Amazonia PDF Author: Miguel N. Alexiades
Publisher: Berghahn Books
ISBN: 9781845455637
Category : Nature
Languages : en
Pages : 334

Book Description
Contrary to ingrained academic and public assumptions, wherein indigenous lowland South American societies are viewed as the product of historical emplacement and spatial stasis, there is widespread evidence to suggest that migration and displacement have been the norm, and not the exception. This original and thought-provoking collection of case studies examines some of the ways in which migration, and the concomitant processes of ecological and social change, have shaped and continue to shape human-environment relations in Amazonia. Drawing on a wide range of historical time frames (from pre-conquest times to the present) and ethnographic contexts, different chapters examine the complex and important links between migration and the classification, management, and domestication of plants and landscapes, as well as the incorporation and transformation of environmental knowledge, practices, ideologies and identities.
