Download or read book Crop Pest Control and Pollination volume II 2nd edition written by Fang Ouyang and published by Frontiers Media SA. This book was released on 2023-12-01 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of food crops helps us meet the basic need of human nutrition. The world's population now exceeds 7 billion people and continues to grow. Alongside this growth, the human demand for food also increases rapidly. Crop production is becoming increasingly intensive and large-scale and, as a result, simplified landscape-systems form. Crop production in simplified agricultural landscapes often face or suffer from various threats, such as pest damage (caused by diseases, insect pests, weeds and rodents) or a shortage of pollinators. These pests can cause serious damage to seeds, germination, growth, breeding and maturity during crop production and food storage, however, effective pest management can help to reduce crop loss. Most crops, in particular fruit trees and vegetables, require insect pollination to ensure high yields and high quality. Research into ecosystem services and their potential impact on pest control and pollination in agricultural landscapes is of great significance to sustainable crop production. Simplified and intensive agricultural landscapes can support crop production, but often have reduced biodiversity as monoculture cropping systems have limited surrounding natural habitat. This lack of natural surrounding habitat leads to the loss of ecosystem service benefits such as natural pest control and pollination. Over the past few decades, pest control has largely relied on chemical pesticides which can control pests and reduce crop losses in the short term. However, chemical pesticides cause a number of problems in the long run, for example, pest resistance to pesticides, and residues of pesticides in soil, water, and agricultural products. Excessive, improper, and long-term use of pesticides during crop production ultimately harms human health and biodiversity, especially beneficial microbes, natural enemies and pollinators. To achieve and ensure food security, food safety and ecological security, new theories, methods, practice, and application patterns need to be developed for environmentally friendly pest control and maintenance of pollination in agricultural landscapes for sustainable food production. The aim of this Research Topic is to promote the sustainable management of crop production and ecological environment protection through the discussion of crop pest control and pollination, and the publication of original research articles and reviews of research and theory. We welcome high-quality and original contributions that present original papers on basic and applied research covering aspects of natural pest control and pollination. Coverage for this Research Topic includes the biology and ecology of pollinators (including wild and managed), organisms (including parasitoids, invertebrate and vertebrate predators of insect pest and plants, mites, plant and insect pathogens, nematodes, and weeds) used for biological control, and aspects of use including biological control agents for integrated pest management on food crops, fruits and vegetables in agricultural landscapes. Natural pest control is an environmentally beneficial and effective means of reducing or mitigating pests and pest damage through the use of natural enemies. Ecological, ethological, molecular, and biotechnological approaches to the understanding of natural pest control and pollination in agricultural landscapes are welcome. Such as, by maintaining and increasing crop genetic diversity (not including genetically engineered crops), crop diversity, species diversity (not including genetically altered insects) and landscape diversity in cropping systems.
Download or read book Principles of Pollination Ecology written by K. Faegri and published by Elsevier. This book was released on 2013-10-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: A completely revised and rewritten edition of this comprehensive survey of the botanical problems of pollination ecology approached from both a theoretical and a practical viewpoint. Examples are drawn from all geographical areas where pollination has been studied and general principles are illustrated by a number of concrete examples. Introductory chapters survey the technical problems and draw comparisons with spore dissemination in cryptogams and pollination in gymnosperms. The following chapters deal with angiosperm pollination and are divided into three parts: organs involved in pollination, flower types and pollinator activities
Download or read book Mutualistic Networks written by Jordi Bascompte and published by Princeton University Press. This book was released on 2013-12-08 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mutualistic interactions among plants and animals have played a paramount role in shaping biodiversity. Yet the majority of studies on mutualistic interactions have involved only a few species, as opposed to broader mutual connections between communities of organisms. Mutualistic Networks is the first book to comprehensively explore this burgeoning field. Integrating different approaches, from the statistical description of network structures to the development of new analytical frameworks, Jordi Bascompte and Pedro Jordano describe the architecture of these mutualistic networks and show their importance for the robustness of biodiversity and the coevolutionary process. Making a case for why we should care about mutualisms and their complex networks, this book offers a new perspective on the study and synthesis of this growing area for ecologists and evolutionary biologists. It will serve as the standard reference for all future work on mutualistic interactions in biological communities.
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.
Download or read book How Landscapes Change written by Gay A. Bradshaw and published by Springer Science & Business Media. This book was released on 2002-12-06 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: North and South America share similar human and ecological histories and, increasingly, economic and social linkages. As such, issues of ecosystem functions and disruptions form a common thread among these cultures. This volume synthesizes the perspectives of several disciplines, such as ecology, anthropology, economy, and conservation biology. The chief goal is to gain an understanding of how human and ecological processes interact to affect ecosystem functions and species in the Americas. Throughout the text the emphasis is placed on habitat fragmentation. At the same time, the book provides an overview of current theory, methods, and approaches used in the analysis of ecosystem disruptions and fragmentation.
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 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.
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.
