Book Synopsis Status of Pollinators in North America by : National Research Council
Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
Book Synopsis The Geographic Mosaic of Coevolution by : John N. Thompson
Download or read book The Geographic Mosaic of Coevolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2005-06-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes. Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.

Book Synopsis Pollinators and Pollination by : Jeff Ollerton
Download or read book Pollinators and Pollination written by Jeff Ollerton and published by Pelagic Publishing Ltd. This book was released on 2021-01-18 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

Book Synopsis Deciphering Chemical Language of Plant Communication by : James D. Blande
Download or read book Deciphering Chemical Language of Plant Communication written by James D. Blande and published by Springer. This book was released on 2016-07-26 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the intricacies of plant communication via volatile chemicals. Plants produce an extraordinarily vast array of chemicals, which provide community members with detailed information about the producer’s identity, physiology and phenology. Volatile organic chemicals, either as individual compounds or complex chemical blends, are a communication medium operating between plants and any organism able to detect the compounds and respond. The ecological and evolutionary origins of particular interactions between plants and the greater community have been, and will continue to be, strenuously debated. However, it is clear that chemicals, and particularly volatile chemicals, constitute a medium akin to a linguistic tool. As well as possessing a rich chemical vocabulary, plants are known to detect and respond to chemical cues. These cues can originate from neighbouring plants, or other associated community members. This book begins with chapters on the complexity of chemical messages, provides a broad perspective on a range of ecological interactions mediated by volatile chemicals, and extends to cutting edge developments on the detection of chemicals by plants.
Download or read book Floral Biology written by David G. Lloyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Book Synopsis The pollination services of forests by : Krishnan, S., Wiederkehr Guerra, G., Bertrand, D., Wertz-Kanounnikoff, S. and Kettle, C.J.
Download or read book The pollination services of forests written by Krishnan, S., Wiederkehr Guerra, G., Bertrand, D., Wertz-Kanounnikoff, S. and Kettle, C.J. and published by Food & Agriculture Org.. This book was released on 2020-06-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most flowering plants, including wild species and many food crops, are pollinated by animals and are vital, therefore, for biological production and the maintenance of biodiversity. Pollinators benefit from diverse natural habitats for forage and nesting, especially when these are limited in plant production systems. Landscape and forest management practices can help ensure the continued availability of pollinators and thereby increase resilience and the productivity of forestry and agriculture. The extent of forests and other natural habitats in a landscape plays a role in determining the species composition of pollinators. Agricultural landscapes adjoining fragmented forests and natural areas benefit from pollinator services, and animal-pollinated crops therefore achieve higher fruit set. Forest management practices can have significant effects on pollinator abundance and diversity. They affect forest variables such as structure, species composition, soil dynamics, hydrology and light availability, all of which can affect pollinator species composition and diversity and plant–pollinator networks. Indigenous and local knowledge can contribute to the conservation of pollinators through traditional management practices. This working paper, which is aimed at forest practitioners, landscape planners and land-use decision-makers, reviews published literature on the impacts of forest and landscape management practices on pollinators. It also addresses the implications of climate change, collates 36 case studies, and makes recommendation on measures for maintaining pollinator diversity and abundance in forests and landscapes
Book Synopsis Cognitive Ecology of Pollination by : Lars Chittka
Download or read book Cognitive Ecology of Pollination written by Lars Chittka and published by Cambridge University Press. This book was released on 2005-08-22 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Important breakthroughs have recently been made in our understanding of the cognitive and sensory abilities of pollinators, such as how pollinators perceive, memorize, and react to floral signals and rewards; how they work flowers, move among inflorescences, and transport pollen. These new findings have obvious implications for the evolution of floral display and diversity, but most existing publications are scattered across a wide range of journals in very different research traditions. This book brings together outstanding scholars from many different fields of pollination biology, integrating the work of neuroethologists and evolutionary ecologists to present a multidisciplinary approach.
Book Synopsis Pollination in Plants by : Phatlane William Mokwala
Download or read book Pollination in Plants written by Phatlane William Mokwala and published by BoD – Books on Demand. This book was released on 2018-06-06 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are the basic source of food for both humans and animals. Most of the food is made of fruits and seeds. For these to be formed, pollination must first take place. This process is the transfer of pollen grains from the anther, which is the male structure of the flower, to the sigma on the female structure of the flower. The transfer process requires agents to be carried out. The agents can be either biotic or abiotic. Nature perfected this arrangement between the pollination agents and the plants. As ecosystems and agricultural systems are changing, this balanced arrangement becomes disturbed. This makes it necessary that pollination systems be studied so that necessary measures can be undertaken to ensure productivity. The chapters of this book present results in research undertaken to improve productivity in crops such as Actinidia chinensis (the kiwifruit), Theobroma cacao (cocoa), and Manicaria saccifera (a tropical forest palm). Some results are presented on tests to check the viability of pollen grains and the delivery of sperm cells through pollen tubes to the embryo sac. These results can serve as guidelines to any person seeking to improve pollination and productivity or to check the efficiency on pollination in ecosystems or agricultural production systems.

Book Synopsis Multitrophic Level Interactions by : Teja Tscharntke
Download or read book Multitrophic Level Interactions written by Teja Tscharntke and published by Cambridge University Press. This book was released on 2002-03-21 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multitrophic level approach to ecology addresses the complexity of food webs much more realistically than the traditional focus on simple systems and interactions. Only in the last few decades have ecologists become interested in the nature of more complex systems including tritrophic interactions between plants, herbivores and natural enemies. Plants may directly influence the behaviour of their herbivores' natural enemies, ecological interactions between two species are often indirectly mediated by a third species, landscape structure directly affects local tritrophic interactions and below-ground food webs are vital to above-ground organisms. The relative importance of top-down effects (control by predators) and bottom-up effects (control by resources) must also be determined. These interactions are explored in this exciting volume by expert researchers from a variety of ecological fields. This book provides a much-needed synthesis of multitrophic level interactions and serves as a guide for future research for ecologists of all descriptions.
