Download or read book Seeds written by Carol C. Baskin and published by Elsevier. This book was released on 1998-06-11 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination differs from all other books on seed germination. It is an all-encompassing volume that provides a working hypothesis of the ecological and environmental conditions under which various kinds of seed dormancy have developed. It also presents information on the seed germination of more than 3500 species of trees, shrubs, vines and herbaceous species, making this a valuable reference for anyone studying germination. This book delivers information on characteristics of each type of seed dormancy, how each type of dormancy is broken in nature, and what environmental conditions are required for germination after dormancy is broken. It explains how studies should be done to distinguish persistent from transient seed banks, and covers which species should be controlled, propagated, and conserved. Seeds gives the reader insight and guidelines for doing ecologically meaningful studies on the biogeography and evolution of seed dormancy and germination in order to better understand plant reproductive strategies, life history traits, adaptations to habitats, and physiological processes. Evolutionary/phylogenetic origins and relationships of various kinds of seed dormancy A world biogeographical perspective on seed dormancy and germination Ecophysiology of seeds with each type of dormancy Critical evaluation of methodology used in soil seed bank studies Germination ecology of plants with specialized habitat and life cycle types Genetic and maternal preconditioning effects on seed dormancy and germination Guidelines for doing ecologically-meaningful germination studies

Download or read book Seed Fate written by J. E. Lambert and published by CABI. This book was released on 2005 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents current knowledge of seed fate in both natural and human-disturbed landscapes, from various regions of the world. Habitats considered range from mountain and arid deserts in the temperate zone, to savanna and lowland rainforests in tropical regions of the world. Particular attention is paid to plant diversity conservation when seed removal is affected by factors such as hunting, habitat fragmentation or intensive logging. Contributors include leading scientists involved in research on seed ecology and on animal-plant relationships from the perspective of both primary and secondary seed dispersal, and predation.

It provides new perspectives and directions at a time when efforts to meet growing environmental challenges threatening natural systems are of utmost importance.
Download or read book Raising Seedlings of Tropical Trees written by Kenneth Alan Longman and published by Commonwealth Secretariat. This book was released on 2003 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planting tropical trees is often hampered by the difficulty of obtaining enough good seed of the right species. After describing the process of sexual reproduction in trees, this manual first looks at the possibilities for stimulating flower formation and for increasing the setting of fruits. It provides all the information necessary to choose the best sources for seeds, and to select the best seeds for a particular planting site. Practical instructions are given on how best to germinate the seeds, and how to nurture and care for the young seedlings.

Download or read book Frugivores and seed dispersal written by Alejandro Estrada and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of plants, ranging in size from forest floor herbs to giant canopy trees, rely on animals to disperse their seeds. Typical values of the proportion of tropical vascular plants that produce fleshy fruits and have animal-dispersed seeds range from 50-90%, depending on habitat. In this section, the authors discuss this mutualism from the plant's perspective. Herrera begins by challenging the notion that plant traits traditionally interpreted as being the product of fruit-frugivore coevolution really are the outcome of a response-counter-response kind of evolutionary process. He uses examples of congeneric plants living in very different biotic and abiotic environments and whose fossilizable characteristics have not changed over long periods of time to argue that there exists little or no basis for assuming that gradualistic change and environmental tracking characterizes the interactions between plants and their vertebrate seed dispersers. A common theme that runs through the papers by Herrera, Denslow et at. , and Stiles and White is the importance of the 'fruiting environment' (i. e. the spatial relationships of conspecific and non-conspecific fruiting plants) on rates of fruit removal and patterns of seed rain. Herrera and Denslow et at. point out that this environment is largely outside the control of individual plant species and, as a result, closely coevolved interactions between vertebrates and plants are unlikely to evolve.
Download or read book Ecology of Soil Seed Banks written by Mary Allessio Leck and published by Elsevier. This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Soil Seed Banks examines the factors that influence seed bank dynamics and the variety of patterns found among different species. This book presents seed banks in a community context to explore the ecological implications of different patterns, and thus begin the development of a synthesis by comparing various communities. Organized into five parts, this book first examines the general processes that influence inputs or losses from the seed bank, including predation, dormancy/germination mechanisms, and their evolutionary importance. Then, this text examines seed banks in a community context. Only eight vegetation types are included, but the range in diversity of life form, length of growing season, and dominant environmental conditions allow comparisons of seed bank patterns. This book also explores the role of seed banks in vegetation management. This reference material will be a valuable reference material to population and community ecologists and managers. Evolutionary consequences of seed banks should be of interest to population and theoretical biologists.

Download or read book Frugivory and seed dispersal ecological and evolutionary aspects written by T.H. Fleming and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any scientific discipline needs a theoretical framework to guide its development and to sharpen the questions its researchers pursue. In biology, evolution is the grand theoretical framework, and an his torical perspective is necessary to understand present-day biological conditions. In its formative years, the modern study of the fruit-frugivore mutualism was guided by the 'specialist-generalist' paradigm developed by D. Snow, D. McKey, and H. Howe. Howe reviews the current status of this evolution ary paradigm and points out that it has been dismissed by many workers before being adequately tested. This is because ecologists working with the tropical plants and frugivorous birds for which the paradigm was originally developed rarely measure the seed dispersal effectiveness of different disperser species. He indicates that this paradigm still has heuristic value and suggests that several additional ecological paradigms, including the concept ofkeystone species ofplants and frugivores and the role that frugivores play in density-dependent mortality in tropical trees, are worth studying. The concept of seed dispersal quality has been central to discussions of fruit-frugivore coevolution. Schupp thoroughly reviews data bearing on this concept, constructs a hierarchical framework for viewing disperser effectiveness, and points out that disperser effectiveness depends on both the quantity and quality of seed dispersal. Effectiveness, in turn, affects both evolutionary and ecological relationships between dispersers and their food plants.
