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.

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.

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.

This book was released on 2013-06-29 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Countless ants transport and deposit seeds and thereby influence the survival, death, and evolution of many plant species. In higher plants, seed dispersal by ants (myrmecochory) has appeared many times independently in different lineages. More than 3000 plant species are known to utilize ant assistance to be planted. Myrmecochory is a very interesting and rather enigmatic form of mutualistic ant-plant associations. This phenomenon is extremely complex, because there are hundreds of ant species connected with hundreds of plant species. This book effectively combines a thorough approach to investigating morphological and physiological adaptations of plants with elegant field experiments on the behaviour of ants. This monograph is a first attempt at collecting information about morphology, ecology and phenology of ants and plants from one ecosystem. The book gives readers a panoramic view of the hidden, poorly-known interrelations not only between pairs of ants and plant species, but also between species communities in the ecosystem. The authors have considered not just one aspect of animal-plant relationships, but have tried to show them in all their complexity. Some aspects of the ant-plant interactions described in the book may be of interest to botanists, others to zoologists or ecologists, but the entire work is an excellent example of the marriage of these biological disciplines.

Download or read book Oak Seed Dispersal written by Michael A. Steele and published by JHU Press. This book was released on 2021-01-05 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive examination of oak forest evolutionary ecology. Seed dispersal is a critical stage in the life cycle of most flowering plants. The process can have far-reaching effects on a species' biology, especially numerous aspects of its ecology and evolution. This is particularly the case for the oaks, in which the dispersal of the acorn is tied to numerous tree characteristics, as well as the behavior and ecology of the animals that feed on and move these seeds to their final destination. Forest structure, composition, and genetics often follow directly from the dispersal process—while also influencing it in turn. In Oak Seed Dispersal, Michael A. Steele draws on three decades of field research across the globe (e.g., the United States, Mexico, Central America, Europe, and China) to describe the interactions between oaks and their seed consumers. Rodents, birds, and insects, he writes, collectively influence the survival, movement, and germination of acorns, as well as the establishment of seedlings, often indicating a coevolutionary bond between oaks and their seed consumers. This bond can only be understood by unraveling the complex interactions that occur in the context of factors such as partial seed consumption due to acorn chemistry, scatterhoarding, predation of the seed consumers by other organisms, and the limiting effects of masting on insect, rodent, and jay damage. Offering new insights on how animal-mediated dispersal drives ecological and evolutionary processes in forest ecosystems, Oak Seed Dispersal also includes an overview of threatened oak forests across the globe and explains how a lack of acorn dispersal contributes to many important conservation challenges. Highly illustrated, the book includes photographs of key dispersal organisms and tactics, as well as a foreword by Stephen B. Vander Wall, a leading authority on food hoarding and animal-mediated seed dispersal, and beautiful artwork by Tad C. Theimer, also an accomplished ecologist.
