Download or read book Species Dispersal in Agricultural Habitats written by Robert Gerald Henry Bunce and published by CRC Press. This book was released on 1990 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes as its theme the fundamental, but still little understood processes whereby plant and animal species disperse through space and over time. The mechanisms of dispersal are complex and varied so the book adopts a thematic perspective, reviewing in the first chapter general principles and then describing surveys of major botanical and zoological groups, primarily, but not exclusively, in agricultural environments. The contributors are all leading specialists in the field and present results from current research. Published in association with the Institute of Terrestrial Ecology, this book is a valuable review of a key field for plant scientists, zoologists, agricultural scientists, ecologists and biogeographers.
Download or read book Dynamic Food Webs written by Peter C de Ruiter and published by Elsevier. This book was released on 2005-12-20 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Food Webs challenges us to rethink what factors may determine ecological and evolutionary pathways of food web development. It touches upon the intriguing idea that trophic interactions drive patterns and dynamics at different levels of biological organization: dynamics in species composition, dynamics in population life-history parameters and abundances, and dynamics in individual growth, size and behavior. These dynamics are shown to be strongly interrelated governing food web structure and stability and the role of populations and communities play in ecosystem functioning. Dynamic Food Webs not only offers over 100 illustrations, but also contains 8 riveting sections devoted to an understanding of how to manage the effects of environmental change, the protection of biological diversity and the sustainable use of natural resources. Dynamic Food Webs is a volume in the Theoretical Ecology series. - Relates dynamics on different levels of biological organization: individuals, populations, and communities - Deals with empirical and theoretical approaches - Discusses the role of community food webs in ecosystem functioning - Proposes methods to assess the effects of environmental change on the structure of biological communities and ecosystem functioning - Offers an analyses of the relationship between complexity and stability in food webs

Download or read book Insect Conservation written by Michael J Samways and published by CABI. This book was released on 2019-12-02 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects do not live in isolation. They interact with the abiotic environment and are major components of the terrestrial and freshwater biotic milieus. They are crucial to so many ecosystem processes and are the warp and weft of all terrestrial and freshwater ecosystems that are not permanently frozen. This means that insect conservation is a two-way process: insects as the subjects of conservation, while also they are useful tools for conserving the environment. This book overviews strategic ways forward for insect conservation. It is a general view of what has worked and what has not for the maintenance of insect diversity across the world, as well as what might be the right approaches for the future.
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 Wetland Book written by C. Max Finlayson and published by Springer. This book was released on 2018-07-04 with total page 1546 pages. Available in PDF, EPUB and Kindle. Book excerpt: In discussion with Ramsar’s Max Finlayson and Nick Davidson, and several members of the Society of Wetland Scientists, Springer is proposing the development of a new Encyclopedia of Wetlands, a comprehensive resource aimed at supporting the trans- and multidisciplinary research and practice which is inherent to this field. Aware both that wetlands research is on the rise and that researchers and students are often working or learning across several disciplines, we are proposing a readily accessible online and print reference which will be the first port of call on key concepts in wetlands science and management. This easy-to-follow reference will allow multidisciplinary teams and transdisciplinary individuals to look up terms, access further details, read overviews on key issues and navigate to key articles selected by experts.
Download or read book Rewilding European Landscapes written by Henrique M. Pereira and published by Springer. This book was released on 2015-05-04 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some European lands have been progressively alleviated of human pressures, particularly traditional agriculture in remote areas. This book proposes that this land abandonment can be seen as an opportunity to restore natural ecosystems via rewilding. We define rewilding as the passive management of ecological successions having in mind the long-term goal of restoring natural ecosystem processes. The book aims at introducing the concept of rewilding to scientists, students and practitioners. The first part presents the theory of rewilding in the European context. The second part of the book directly addresses the link between rewilding, biodiversity, and habitats. The third and last part is dedicated to practical aspects of the implementation of rewilding as a land management option. We believe that this book will both set the basis for future research on rewilding and help practitioners think about how rewilding can take place in areas under their management.
Download or read book Conserving Biodiversity in Agricultural Landscapes written by Robert K. Swihart and published by Purdue University Press. This book was released on 2004 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat loss and fragmentation arguably pose the greatest threats to biological diversity. Agriculture is a dominant land use that, along with urban sprawl and residential development, can reduce the amount and connectedness of natural areas required by many native species. Unfortunately, progress has been slow in integrating nature and biodiversity protection into community planning in intensively farmed regions, especially in America's heartland. Seldom do issues related to species conservation receive consideration during local planning activities. Lack of progress stems partly from scientific inadequacies in understanding the dynamics of complex landscapes, and from a lack of engagement of non-scientific stakeholders by scientists and modelers. The result of these shortcomings is a critical disconnect of conservation issues from the planning infrastructure. This book provides a blueprint for advancing conceptual understanding of conservation in agricultural regions. It accomplishes this with a two-pronged approach: first, by developing spatially structured models that acknowledge the link between socio-economic drivers of land-use change and the dynamics of species occupying agricultural landscapes with abrupt changes in land cover (i.e., sharp edges); and second, by providing guidelines and examples to enable scientists to effectively engage stakeholders in participatory learning and planning activities that integrate biodiversity with other, more traditional, considerations. The structure of the book is truly interdisciplinary, linking the efforts of ecologists, economists, statisticians, mathematicians, and land-use specialists.
Download or read book Gene Pool Diversity and Crop Improvement written by Vijay Rani Rajpal and published by Springer. This book was released on 2016-02-02 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population is estimated to reach to more than 10 billion by the year 2050. These projections pose a challenging situation for the agricultural scientists to increase crops productivity to meet the growing food demands. The unavailability and/or inaccessibility to appropriate gene pools with desired traits required to carry out genetic improvement of various crop species make this task formidable for the plant breeders. Incidentally, most of the desired genes reside in the wild genetic relatives of the crop species. Therefore, exploration and characterization of wild genetic resources of important crop species is vital for the efficient utilization of these gene pools for sustainable genetic improvements to assure food security. Further, understanding the myriad complexities of genic and genomic interactions among species, more particularly of wild relatives of crop species and/or phylogenetically distant germplasm, can provide the necessary inputs to increase the effectiveness of genetic improvement through traditional and/or genetic engineering methods. This book provides comprehensive and latest insights on the evolutionary genesis of diversity, access and its utilization in the evolution of various crop species. A comprehensive account of various crops, origin, exploitation of the primary, secondary and tertiary gene pools through breeding, biosystematical, cytogenetical and molecular phylogenetical relationships, and genetic enhancement through biotechnological interventions among others have been provided as the necessary underpinnings to consolidate information on the effective and sustainable utilization of the related genetic resources. The book stresses upon the importance of wild germplasm exploration, characterization and exploitation in the assimilation of important crop species. The book is especially intended for students and scientists working on the genetic improvement of crop species. Plant Breeders, Geneticists, Taxonomists, Molecular Biologists and Plant Biotechnologists working on crop species are going to find this book very useful.

Download or read book Species Survival in Fragmented Landscapes written by J. Settele and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of isolation, area size, and habitat quality on the survival of animal and plant populations in the cultural landscape are central aspects of a research project started in Germany in 1993 (,Forschungsverbund, Isolation, FHichengroBe und BiotopquaIiHit', abbreviated to 'FIFB'). After a long period of preparation, scientists from seven univer sities and one research institution started to work within the frame of this project. Fund ing for four years was provided by the former German Federal Ministry of Research and Technology (BMFT), now the Ministry of Education and Research (BMBF). A strong focus of the project has been the improvement of the methodology for environmental impact assessments and the implementation of results into environmental planning. As there is a certain risk that national projects develop some kind of 'mental in breeding', it was decided to discuss concepts, methods, and first results with scientists of international reputation at a rather early stage of the project. For this purpose, an inter national workshop was held in the small village of Lubast, north of Leipzig (state of Saxony) in March 1995. 130 scientists from 10 nations met to discuss and debate issues surrounding habitat fragmentation for three days. Papers presented there formed the basis for this book. As discussions included general reviews as well as particular case studies, we decided to structure this book in a similar way. Consequently, a combination of broad and more general, review-like papers as well as original papers are presented.
