Download or read book Microbial Ecology of Leaves written by John H. Andrews and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The leaf surface or phyllosphere is a major habitat for microorganisms. Microbes on or within leaves play important roles in plant ecology, and these microbes can be manipulated to enhance plant growth or reduce plant disease. This book presents a number of critical reviews by internationally recognized experts on the microbial ecology of leaves. Topics include methods of assessment of microbial populations on leaf surfaces, leaves as reservoirs of ice nucleation phenomenon, and leaves as microbial habitats in both aquatic and terrestrial environments. The book will be of interest to students and scientists in numerous disciplines, including botany, aerobiology, meteorology, ecology, agriculture, and microbiology.
Download or read book Modern Trends in Applied Terrestrial Ecology written by R.S. Ambasht and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and economics have Greek roots in oikos for "household", logos for "study", and nomics for "management". Thus, ecology and economics should have complemented one another for a proper growth and development without destruction, but, unfortunately, rapid industrialization, lure for fast financial gains, and commercialization activities have led to a widespread surge in pollution load, environmental degradation, habitat destruction, rapid loss ofbiodiversity, sudden rise in rate ofextinction ofmany wildlife and wild relatives of domesticated animals and cultivated cereals and other plants, global climate changes creating global rise in temperature, and CO levels and increased ultraviolet B at ground 2 level. Although these threats to human health have led us to look to ecology for their solutions and guidance for sustainable development without destruction, the industrial and technology houses are looking for alternative methods of development and resource use methods. The two global conferences of the United Nations in 1972 and 1992, and international programs of Man and the Biosphere (MAB), International Biological Program (IBP), International Geosphere, Biosphere program (lGBP), and World Conser vation Union (IUCN), of different commissions, United Nations Environmental Program (UNEP) efforts, Ramsar Conventions (for wetlands), and World Wide fund for Nature (WWF) (for nature in general and wildlife in particular) have focused attention of ecologists, naturalists, governments and Non-governmental organizations (NGOs) toward better conservation.
Download or read book Field Crop Arthropod Pests of Economic Importance written by Peter A. Edde and published by Academic Press. This book was released on 2021-08-21 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. Includes insect synonyms, common names, and geographic distribution Provides information on natural enemies Is thoroughly referenced for future research

Download or read book Genetic and Genomic Resources of Grain Legume Improvement written by Mohar Singh and published by Newnes. This book was released on 2013-07-18 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain legumes, including common-bean, chickpea, pigeonpea, pea, cowpea, lentil and others, form important constituents of global diets, both vegetarian and non-vegetarian. Despite this significant role, global production has increased only marginally in the past 50 years. The slow production growth, along with a rising human population and improved buying capacity has substantially reduced the per capita availability of food legumes. Changes in environmental climate have also had significant impact on production, creating a need to identify stable donors among genetic resources for environmentally robust genes and designing crops resilient to climate change. Genetic and Genomic Resources of Grain Legume Improvement is the first book to bring together the latest resources in plant genetics and genomics to facilitate the identification of specific germplasm, trait mapping and allele mining to more effectively develop biotic and abiotic-stress-resistant grains. This book will be an invaluable resource for researchers, crop biologists and students working with crop development. Explores origin, distribution and diversity of grain legumes Presents information on germplasm collection, evaluation and maintenance Offers insight into pre-breeding/germplasm enhancement efforts Integrates genomic and genetic resources in crop improvement Internationally contributed work
