Book Synopsis Frugivory and seed dispersal: ecological and evolutionary aspects by : T.H. Fleming

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.

Book Synopsis Closing the Seed Dispersal Loop for Guettarda Viburnoides (Rub.) by : Andrea Patricia Loayza
Download or read book Closing the Seed Dispersal Loop for Guettarda Viburnoides (Rub.) written by Andrea Patricia Loayza and published by . This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed dispersal by vertebrates in the tropics is a key ecological process; therefore, understanding its consequences for plant fitness is a central question of plant population ecology. Little is known, however, of how frugivore activity translates into demographic and evolutionary consequences for plants. In this study, I connect data on frugivore activity, post-dispersal seed fate and plant population demography using stage-specific demographic modeling, to examine the role of individual dispersers for plant population dynamics of the fleshy-fruited Neotropical tree Guettarda viburnoides (Rubiaceae) in northeastern Bolivian savannas. In chapter one, I examine avian frugivory and seed dispersal of G. viburnoides, focusing on the quantitative and qualitative aspects of disperser effectiveness. The endocarps of this plant are dispersed primarily by two species: Cyanocorax cyanomelas and Pteroglossus castanotis, which I identify as the quantitatively important dispersers (QID) of G. viburnoides. These two species differ in several qualitative aspects of seed dispersal: 1) They select fruits of different sizes; 2) they differ in their fruit handling treatment, which in turn affects the probability of seedling emergence, the temporal pattern of emergence, and the number of emerged seedlings per endocarp and; 3) they differ in their landscape patterns of seed deposition. These results suggest that C. cyanomelas and P. castanotis differ in the quality of seed dispersal services they provide to G. viburnoides. In chapter two, I analyze how habitat affects the post-dispersal seed fate of G. viburnoides. The results show that habitat strongly affects seed dispersal, seed predation, and seedling emergence. Additionally, uncoupling among different life-stages occurs in all habitats and there is spatial discordance between the seed rain and sapling recruitment patterns. This discordance suggests that, in certain years at least, habitat available for recruitment of G. viburnoides in this landscape is limited. The results also reveal high inter-annual variability in the strength of post-dispersal processes, which leads to a constant shifting of habitat "suitability" from one year to the next; that is, it is context-dependent. Finally, in chapter three, I determine the individual effect of seed dispersal by C. cyanomelas and P. castanotis on population growth of G. viburnoides, and assess the degree to which these species may be ecologically redundant. The results demonstrate that seed dispersal by C. cyanomelas leads to positive population growth of G. viburnoides, whereas seed dispersal by P. castanotis has a detrimental effect on the population growth of this species. Therefore, C. cyanomelas is a key species for the long-term persistence of G. viburnoides, and the loss of this dispersal agent would not be compensated by the dispersal services provided by P. castanotis. Ultimately, the integration of frugivore activity with plant demography using models such as this one are important for plant ecology because they enable us to close the "seed dispersal loop" and gain a better understanding of the demographic consequences of seed dispersal by different dispersal agents.

Book Synopsis Tropical Forest Community Ecology by : Walter Carson
Download or read book Tropical Forest Community Ecology written by Walter Carson and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems

Book Synopsis Structured-Population Models in Marine, Terrestrial, and Freshwater Systems by : Shripad Tuljapurkar
Download or read book Structured-Population Models in Marine, Terrestrial, and Freshwater Systems written by Shripad Tuljapurkar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the summer of 1993, twenty-six graduate and postdoctoral stu dents and fourteen lecturers converged on Cornell University for a summer school devoted to structured-population models. This school was one of a series to address concepts cutting across the traditional boundaries separating terrestrial, marine, and freshwa ter ecology. Earlier schools resulted in the books Patch Dynamics (S. A. Levin, T. M. Powell & J. H. Steele, eds., Springer-Verlag, Berlin, 1993) and Ecological Time Series (T. M. Powell & J. H. Steele, eds., Chapman and Hall, New York, 1995); a book on food webs is in preparation. Models of population structure (differences among individuals due to age, size, developmental stage, spatial location, or genotype) have an important place in studies of all three kinds of ecosystem. In choosing the participants and lecturers for the school, we se lected for diversity-biologists who knew some mathematics and mathematicians who knew some biology, field biologists sobered by encounters with messy data and theoreticians intoxicated by the elegance of the underlying mathematics, people concerned with long-term evolutionary problems and people concerned with the acute crises of conservation biology. For four weeks, these perspec tives swirled in discussions that started in the lecture hall and carried on into the sweltering Ithaca night. Diversity mayor may not increase stability, but it surely makes things interesting.
Download or read book Seed Dispersal written by David R. Murray and published by Academic Press. This book was released on 2012-12-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed Dispersal focuses on the mechanics and processes involved in seed dispersal, including its implications in ecology, animal behavior, plant and animal biogeography, speciation, and evolution. The selection first elaborates on the aerial motion of seeds, fruits, spores, and pollen and seed dispersal by water. Discussions focus on seed dispersal by rain, river, and flood, effective seed dispersal by ocean currents compared to other vectors, aerodynamic forces and their effects, and launching and release mechanisms. The text then takes a look at seed dispersal syndromes in Australian Acacia, including inference of dispersal syndromes, seed dispersal syndromes, ecological consequences of seed dispersal, and evolutionary derivation of dispersal syndromes. The publication ponders on seed dispersal by fruit-eating birds and mammals, rodents as seed consumers and dispersers, and seed dispersal in relation to fire. Topics include fire as a dispersal vector, long distance dispersal, granivorous rodents and the fates of seeds, determinants of the fate path, population ecology of seed dispersal, and foraging for fruits. The selection is a valuable reference for researchers interested in the factors involved in seed dispersal.

Download or read book The Natural History of Flowers written by Michael Fogden and published by Texas A&M University Press. This book was released on 2018-09-05 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flowers have played an important role in human culture and survival for thousands of years. The final products of flowers—fruits and seeds—are vitally important as food. Flowers provide bursts of color to homes and gardens and they symbolize love, sorrow, and renewal. Yet we often overlook their real purpose. Why do flowers exist and why do they have certain colors, shapes, and smells? What function does a flower have in the life and survival of the plants themselves? In nature, flowers play an essential role in improving a plant’s chances of survival. Some flowers are pollinated by wind or water but most are designed to attract and reward pollinators, such as bees, butterflies, birds, and bats, to carry their pollen from flower to flower. After being pollinated, flowers produce fruits and again take advantage of wind, water, and animals to disperse their seeds, ensuring a new generation of their species. Pollination and seed dispersal are fine-tuned systems, and their importance in sustaining a healthy environment cannot be overstated. And, as ongoing climate and other environmental changes apply new pressures, flowers must continue to adapt in order to survive. In this beautifully illustrated book with over 200 stunning photographs, Michael Fogden and Patricia Fogden draw from existing research and their extensive field experiences all over the world to present a detailed but accessible introduction to the natural history of flowers. They discuss a representative sample of flowering and fruiting strategies, illustrating interactions between plants and their pollinators and dispersers, and conclude with descriptions of their favorite tropical flowers.
