This book was released on 2008-10-01 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although people have been altering earth’s landscapes to some extent for tens of thousands of years, humankind today is causing massive changes to the planet. Such widespread environmental change is accompanied by accelerating rates of species extinction. In this book, noted ecologist H. H. Shugart presents important ecological concepts through entertaining animal parables. He tells the stories of particular birds and mammals—the packrat, ivory-billed woodpecker, penguin, dingo, European rabbit, and others—and what their fates reveal about the interactions between environmental change and the extinctions or explosions of species populations. Change is the root of many planetary problems, but it is also an intrinsic feature of our living planet. Shugart explores past environmental change, discusses the non-existence of a “balance of Nature,” and documents how human alterations have affected plants, soils, and animals. He looks with hope toward a future in which thoughtful people learn—and use—ecological science to protect the landscapes upon which terrestrial creatures depend.
Download or read book Strangers in Paradise written by Daniel Simberloff and published by Island Press. This book was released on 1997-04 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive nonindigenous species -- plants and animals that have been introduced to an ecosystem from someplace else -- are wreaking havoc around the globe. Because they did not co-evolve with species already in the ecosystem, they can profoundly disturb species interactions and ecosystem function.The state of Florida has one of the most severe exotic species problems in the country; as much as a quarter of many taxa in Florida are nonnative, and millions of acres of land and water are dominated by nonindigenous species. Strangers in Paradise provides an in-depth examination of the Florida experience and of the ongoing efforts to eradicate or manage introduced species. Chapters consider: natural disturbance and the spread of nonindigenous species case studies of insects, freshwater invertebrates, fishes, amphibians and reptiles, birds, marine invertebrates and algae, and mammals methods of managing nonindigenous species including ecological restoration, eradication, "maintenance control," and biological control management on public lands the regulatory framework including the role of the federal government as well as state authorities and responsibilities Strangers in Paradise is the first comprehensive volume to address a large, diverse region and the full range of nonindigenous species, the problems they cause, and the methods and impediments to dealing with them. Throughout, contributors emphasize solutions and relate the situation in Florida to problems faced by other states, making the book an important guide for anyone involved with control and management of invasive species.

Download or read book The Problems of Birds as Pests written by R. K. Murton and published by Elsevier. This book was released on 2013-09-03 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Problems of Birds as Pests covers the proceedings of the symposium held at the Royal Geographical Society in London on 28 and 29 September 1967. The text focuses on the problems posed by birds on agriculture and air transport, as well as control of population, scaring techniques, and warning systems. The selection first discusses prospective considerations concerning bio-acoustics in relation to bird-scaring techniques and recent developments in bird scaring on airfields. Topics include system of behavior and hierarchy of signals, informative content of acoustic signals, and signal-noise ratio. The book also ponders on bird recognition by radar and bird warning system for aircrafts in flight. The publication reviews the rook issue in North-East Scotland and the problems brought by the oystercatchers, including availability of field crops and their utilization by rooks, rook population, and food intake of the birds and comparison with stock and fishing levels. The manuscript then surveys predator-prey relationships in bird damage and population control and the quelea problem in Africa. The selection is a valuable source of information for ornithologists and readers interested in the characteristic of birds as pests.

Download or read book The Agricultural Sky written by K. R. Krishna and published by CRC Press. This book was released on 2023-06-02 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The agricultural sky" is a dominant natural entity that has influenced, interacted with, and guided the evolution of crops, farming practices, and cropping systems. The sky—and all its components—above and near agricultural areas is an important aspect of an agricultural enterprise—as important as soils, water, and crop species. The blue sky above crops that is seemingly clear, tranquil or sometimes filled with clouds, is really a repository of a large number of gases, mineral or organic particulate matter, dust, mist, turbulent wind, innumerable species of micro-organisms, tiny biotic flora/fauna, seeds, insects, etc. The agrarian sky supports complex interactions of biotic and abiotic aspects with perhaps immediate and/or delayed influence on crops sown on the ground. This volume helps us to better understand the importance of the sky above crop fields, with the goal to encourage revolutionary agronomic procedures that lead to higher yield. It is a comprehensive treatise on the agriculture sky, covering basic definitions, limits, and explanations about atmospheric layers like troposphere, stratosphere, and the phyllosphere. The volume addresses the nutrient dynamics in the sky and their relevance to crop productivity. It looks at both natural biotic and manmade abiotic factors in the sky and how they affect what goes on below, such as from dust storms, at cloudy and/or windy locations, and from high-altitude jet streams. The author discusses wind and solar power generation in the agrarian sky and explores aeroponics to revolutionize crop production. The volume delves into several types of aerial robots, employing AI and other technology, to provide aerial spectral data that are capable of analyzing procedures, soil conditions, irrigation, insect pests, weed detection, herbicide application, soil fertility, and much more. The book includes examples from the North American Great Plains, Pampas of Argentina, Sahelian production zones of West Africa, Indo-Gangetic Plains, etc. This eye-opening book, The Agricultural Sky: A Concept to Revolutionize Farming, will be useful to students and professors in universities as well as to researchers in industry dealing with aerial aspects of farming.

Download or read book Granivorous Birds in Ecosystems written by Jan Pinowski and published by Cambridge University Press. This book was released on 2012-03-29 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 1977. It deals with the importance of weed seed and grain-eating birds in natural and agricultural environments. These birds are to be found worldwide and are a component of man-made ecosystems where they are associated with man's main food crops. An analysis is made of their evolution and genetics, population dynamics, energy and food requirements, impact on ecosystems and control. Principles, procedures and basic data are presented that can be applied to the evaluation and control of pest species anywhere in the world. In this synthesis volume full use is made of the systems approach, the ecological and evolutionary aspects of the study are integrated. In linking the studies with fundamental work on bioenergetics, new insights are provided into the behavioural and applied aspects of granivory. Studies which encompass archaeological and anthropological investigations form a backcloth for the detailed interpretation of the population biology and bioenergetics of birds.

Download or read book Pests written by Ross Piper and published by Bloomsbury Publishing USA. This book was released on 2011-03-03 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This single volume describes the animals that are most injurious and costly to humans, examining the important roles of these pests throughout history and the implications of the never-ending wars we wage against the natural world. From mosquitoes to nematodes to mice, there are a multitude of organisms and animals that pose major health risks, cause economic burdens, and even threaten famine conditions for human civilization. Addressing these problems is often extremely costly and only partially effective. Pests: A Guide to the World's Most Maligned, Yet Misunderstood Creatures presents an overview of the animals that have the greatest impact on our lives, from the creatures that eat our crops through the ones that invade our homes and those that transmit diseases. Each entry provides a brief history of our interactions with the specific pest, methods of management or eradication for the pest being discussed, and an extensive Further Reading list that includes resources on both the biology of the pest and methods of control. The author explains the complexity of the worldwide pest problem and demonstrates how some of these issues are a result of human over-population and shortsightedness, inviting readers to consider our place in nature and how other animals have adapted to and benefited from the growing human population.

Download or read book Vision Infinity for Food Security written by Shashi B. Sharma and published by Springer. This book was released on 2015-09-04 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new perspective on the global food security situation and highlights the need for seeking a common vision and implementing global planning to define the manner in which the human species will manage its food security. The basic question of ‘is there enough food’ is examined in general and then in some detail. The history of food production is reviewed in the hope that lessons can be learned from the past. But even after ten thousand years of experience we are not able to feed adequately about a third of our total population, despite what statistics can be made to tell us. Intensive agriculture has stripped out the nutrients that support plant growth and marginalised extensive tracts of land. The global solution to feed the growing population has been and continues to be – produce more food. Even during the last 30 years, about 95 percent of global research investments have focused mainly on increasing productivity. However about a third of the food produced, sufficient to feed over two billion hungry people, is lost or wasted in the food value chain. Climate change is another confounding factor that impinges on our discussions. Pests of all kinds continue to destroy food before and after it is harvested, even though the technology to protect it is available. A huge amount of food is wasted in value chains, particularly at the domestic level. Global food production systems are exposed to unprecedented biosecurity risks posed by invasive harmful organisms and this trend is likely to further exacerbate as current approach to biosecurity is based on the notional premise that lines on maps and the legislation that goes with them is sufficient to halt epidemics. Solutions include extending the number of cultivated plant and animal species to include those that can prosper in what are currently considered to be extreme environments.
