Download or read book Biological Control in Latin America and the Caribbean written by Joop C. van Lenteren and published by CABI. This book was released on 2019-12-21 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes the history of biological control in Latin America and the Caribbean. Few publications provide historical detail and the records are, therefore, fragmented until now. By bringing information together in this book, we offer a more complete picture of important developments in biological control on this continent. There are a wealth of text, tables and references about the history of such projects, and which were succesful and which failed. This will help plan future biocontrol projects. An overview is provided of the current situation in biological control for many Latin American and Caribbean countries, revealing an astonishing level of practical biological control applied in the regio, making it the largest area under biological control worldwide. The final part describes new developments and speculates about the future of biological control in Latin America and the Caribbean.

Available in PDF, EPUB and Kindle. Book excerpt: The papers presented in this book cover the range of forest insect pest management activities in Canada. The first section contains papers on the current status of insect pests by region, including data on insect populations and extent of defoliation caused by the insect. The next section covers pest management technology, including the use of insecticides, insect viruses, fungal pathogens, growth regulators, antifeedants, pheromones, natural predators, and aerial spraying. The third section contains papers on the application of technology and equipment for forest pest control, and includes papers on the impacts of insecticides on the forest environment. The fourth section describes operational control programs by province. The final paper presents future strategies for the management of forest pests. An author index is included.

Download or read book Natural Processes and Human Impacts written by Sergey M. Govorushko and published by Springer Science & Business Media. This book was released on 2011-10-13 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly topical book comes at a time when the two-way relationship between humankind and the environment is moving inexorably to the top of the agenda. It covers both sides of this delicate balancing act, explaining how various natural processes influence humanity, including its economic activities and engineering structures, while also illuminating the ways in which human activity puts pressure on the natural environment. Chapters analyze a varied selection of phenomena that directly affect people’s lives, from geological processes such as earthquakes and tsunamis to cosmic events such as magnetic storms. The author moves on to consider the effect we have on nature, ranging from the impact of heavy industry to the environmental consequences of sport and recreational pastimes. Complete with maps, photographs and detailed case studies, this book provides a comprehensive overview of the biggest issue we face as a species—the way we relate to the natural world around us. This book includes more than 100 maps showing the global distribution of different natural processes/human activities and more that 450 photographs from many countries and all oceans. It will provide a valuable resource for both graduate students and researchers in many fields of knowledge. Sergey Govorushko is a chief research scholar at the Pacific Geographical Institute, Russian Academy of Sciences. He is also Professor at the Far Eastern Federal University (Vladivostok). Sergey Govorushko received his PhD from the Institute of Geography, Russian Academy of Sciences. His research activities focus on the interaction between humanity and the environment, including the impact of nature on humanity; the impact of humanity on the environment; and assessment of the interaction (environmental impact assessment, environmental audit, etc.). He has authored eight and co-authored seven monographs.

Available in PDF, EPUB and Kindle. Book excerpt: There are few books available that provide a good introduction tothe methods and techniques for ecological research. This book willbe invaluable to lecturers teaching field courses and studentsundertaking project work in ecology. Each chapter will focus on an ecological technique. It will havean introductory section that describes the ecological principlesand theory. This will then be followed by example applications.These will focus on three most common habitats where teachers takestudents for fieldwork; the seashore, ponds and lakes, fields andwoodland. Gives specific worked examples from the main ecosystems usedfor undergraduate study - seashore, lakes/ponds, field andwoodland. Only introductory text specifically focused on fieldtechniques. Great 'how-to' guide that will show student exactly how tocarry out each method. Only text to emphasise the principles behind the techniques -taking a methods based approach rather than a taxonomic approach(eg chapters split into population measures, biodiversity measures,species richness measures rather than methods for invertebrates,methods for mammals, methods for birds etc). Greater emphasis on the equipment involved - how to make it,where to buy it. Good references to further reading and advancedtechniques.

Available in PDF, EPUB and Kindle. Book excerpt: The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.
