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.

Download or read book The Andean Cloud Forest written by Randall W. Myster and published by Springer Nature. This book was released on 2020-11-12 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book focused solely on Andean Cloud Forests (ACF) has never been published. ACF are high biodiversity ecosystems in the Neotropics with a large proportion of endemic species, and are important for the hydrology of entire regions. They provide water for large parts of the Amazon basin, for example. Here I take advantage of my many years working in ACF in Ecuador, to edit this book that contains the following sections: (1) ACF over space and time, (2) Hydrology, (3) Light and the Carbon cycle, (4) Soil, litter, fungi and nutrient cycling, (5) Plants, (6) Animals, and (7) Human impacts and management. Under this premise, international experts contributed chapters that consist of reviews of what is known about their topic, of what research they have done, and of what needs to be done in the future. This work is suitable for graduate students, professors, scientists, and researcher-oriented managers.

Download or read book The Butterflies of Venezuela: Nymphalidae I (Limenitidinae, Apaturinae, Charaxinae) written by Andrew F. E. Neild and published by Apollo Books. This book was released on 1996 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part 1 of The Butterflies of Venezuela was a pioneering work of its kind for South America, being the first authoritative volume in a comprehensive faunistic identification series. The series will prove invaluable to all who wish to learn about the remarkable and diverse butterfly fauna of this country and continent. Approximately 1000 species of adult Nympbalidae, Papilionidae, and Pieridae will be treated in the four-part series, equivalent to over one-third of the total Neotropical species in these families. Drawing on over 20 years of personal research in the field, in collections, and in libraries, the detailed accounts for each species encapsulate all that is known about their identification, distribution, behaviour, habitat, and foodplants. The text, which has been written to appeal to specialists and amateurs alike, has been collated from a wealth of published and unpublished sources. It includes extensive commentary on the systematics and nomenclature employed, and provides detailed notes designed to permit the easy identification of every Venezuelan butterfly. General notes on early stages are provided in the introduction to each genus, and where available those of one representative species are fully described. Readers also benefit from the inclusion of an extensive bibliography, which in Part 2 alone comprises almost 800 works fully referenced in the text. Unlike many other guides, the photographic colour plates illustrate every subspecies, generally showing both sexes and wing surfaces for each, plus several representative specimens for highly variable taxa. In addition, a large number of type specimens are reproduced, many of them for the first time. Part 1 cover 276 species including 2 new species and 23 new subspecies. Part 2 treats 196 species incl. 355 subspecies and the colour plates figures over 450 type specimens. 8 new species and 95 new spubspecies are described. 4 neotypes and 10 lectopypes are designated. Part 3 is projected to treat the Papilionidae, Brassolinae, Danainae, and first part of Satyrinae (Pronophilina and Erebiina). Part 4 will cover the family Pieridae and the remaining Satyrinae and Heliconiinae.

Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Download or read book Coevolution of Animals and Plants written by Lawrence E. Gilbert and published by University of Texas Press. This book was released on 1980-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognized that plants and animals profoundly affect one another’s characteristics during the course of evolution. However, the importance of coevolution as a dynamic process involving such diverse factors as chemical communication, population structure and dynamics, energetics, and the evolution, structure, and functioning of ecosystems has been widely recognized for a comparatively short time. Coevolution represents a point of view about the structure of nature that only began to be fully explored in the late twentieth century. The papers presented here herald its emergence as an important and promising field of biological research. Coevolution of Animals and Plants is the first book to focus on the dynamic aspects of animal-plant coevolution. It covers, as broadly as possible, all the ways in which plants interact with animals. Thus, it includes discussions of leaf-feeding animals and their impact on plant evolution as well as of predator-prey relationships involving the seeds of angiosperms. Several papers deal with the most familiar aspect of mutualistic plant-animal interactions—pollination relationships. The interactions of orchids and bees, ants and plants, and butterflies and plants are discussed. One article provides a fascinating example of more indirect relationships centered around the role of carotenoids, which are produced by plants but play a fundamental part in the visual systems of both plants and animals. Coevolution of Animals and Plants provides a general conceptual framework for studies on animal-plant interaction. The papers are written from a theoretical, rather than a speculative, standpoint, stressing patterns that can be applied in a broader sense to relationships within ecosystems. Contributors to the volume include Paul Feeny, Miriam Rothschild, Christopher Smith, Brian Hocking, Lawrence Gilbert, Calaway Dodson, Herbert Baker, Bernd Heinrich, Doyle McKey, and Gordon Frankie.

Download or read book The Physical Geography of South America written by Thomas T. Veblen and published by Oxford University Press. This book was released on 2015-04-01 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge about this mostly tropical continent, together with its high mountains and temperate southern cone. The authors systematically cover the main components of the South American environment - tectonism, climate, glaciation, natural landscape changes, rivers, vegetation, animals, and soils. The book then presents more specific treatments of regions with special attributes from the tropical forests of the Amazon basin to the Atacama Desert and Patagonian steppe, and from the Atlantic, Caribbean, and Pacific coasts to the high Andes. Additionally, the continents environments are given a human face by evaluating the roles played by people over time, from pre-European and European colonial impacts to the effects of modern agriculture and urbanization, and from interactions with El Niño events to prognoses for the future environments of the continent.
