Download or read book The Forgotten Pollinators written by Stephen L. Buchmann and published by Island Press. This book was released on 2012-06-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consider this: Without interaction between animals and flowering plants, the seeds and fruits that make up nearly eighty percent of the human diet would not exist. In The Forgotten Pollinators, Stephen L. Buchmann, one of the world's leading authorities on bees and pollination, and Gary Paul Nabhan, award-winning writer and renowned crop ecologist, explore the vital but little-appreciated relationship between plants and the animals they depend on for reproduction -- bees, beetles, butterflies, hummingbirds, moths, bats, and countless other animals, some widely recognized and other almost unknown. Scenes from around the globe -- examining island flora and fauna on the Galapagos, counting bees in the Panamanian rain forest, witnessing an ancient honey-hunting ritual in Malaysia -- bring to life the hidden relationships between plants and animals, and demonstrate the ways in which human society affects and is affected by those relationships. Buchmann and Nabhan combine vignettes from the field with expository discussions of ecology, botany, and crop science to present a lively and fascinating account of the ecological and cultural context of plant-pollinator relationships. More than any other natural process, plant-pollinator relationships offer vivid examples of the connections between endangered species and threatened habitats. The authors explain how human-induced changes in pollinator populations -- caused by overuse of chemical pesticides, unbridled development, and conversion of natural areas into monocultural cropland-can have a ripple effect on disparate species, ultimately leading to a "cascade of linked extinctions."
Download or read book Seedling Ecology and Evolution written by Mary Allessio Leck and published by Cambridge University Press. This book was released on 2008-09-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.

Available in PDF, EPUB and Kindle. Book excerpt: This new collection focuses on the impact of sprawl on biodiversity and the measures that can be taken to alleviate it. Leading biological and social scientists, conservationists, and land-use professionals examine how sprawl affects species and alters natural communities, ecosystems, and natural processes. The contributors integrate biodiversity issues, concerns, and needs into the growing number of anti-sprawl initiatives, including the "smart growth" and "new urbanist" movements.
Download or read book Pollination Biology written by Dharam P. Abrol and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Download or read book Tropical Forest Canopies Ecology and Management written by K.E. Linsenmair and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost half of all life on earth may exist in the world's forest canopies. They may also play a vital role in maintaining the planet's climate, yet they remain largely unexplored owing to difficulties of access. They are renowned for their great diversity and role in forest functioning, yet there are still great gaps in the understanding of this `last biological frontier'. This seminal book shows how canopy science is now in a position to answer many of the outstanding questions, among which are some of the most pressing environmental issues society is presently facing. It represents a major summary of the current understanding of canopy ecology, and maps a path forward into a greater understanding of tropical forest ecology and management at a time when the very future of this ecosystem is threatened by humanity's actions.
Download or read book Insect Biodiversity written by Robert G. Foottit and published by John Wiley & Sons. This book was released on 2018-04-11 with total page 1635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume Two of the new guide to the study of biodiversity in insects Volume Two of Insect Biodiversity: Science and Society presents an entirely new, companion volume of a comprehensive resource for the most current research on the influence insects have on humankind and on our endangered environment. With contributions from leading researchers and scholars on the topic, the text explores relevant topics including biodiversity in different habitats and regions, taxonomic groups, and perspectives. Volume Two offers coverage of insect biodiversity in regional settings, such as the Arctic and Asia, and in particular habitats including crops, caves, and islands. The authors also include information on historical, cultural, technical, and climatic perspectives of insect biodiversity. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and examine the consequences that an increased loss of insect species will have on the world. This important text: Offers the most up-to-date information on the important topic of insect biodiversity Explores vital topics such as the impact on insect biodiversity through habitat loss and degradation and climate change With its companion Volume I, presents current information on the biodiversity of all insect orders Contains reviews of insect biodiversity in culture and art, in the fossil record, and in agricultural systems Includes scientific approaches and methods for the study of insect biodiversity The book offers scientists, academics, professionals, and students a guide for a better understanding of the biology and ecology of insects, highlighting the need to sustainably manage ecosystems in an ever-changing global environment.
