We Pointed Them North - Recollections of a Cowpuncher (Paperback, New edition): E.C. Abbott, Helena Huntington Smith We Pointed Them North - Recollections of a Cowpuncher (Paperback, New edition)
E.C. Abbott, Helena Huntington Smith

E. C. Abbott was a cowboy in the great days of the 1870's and 1880's. He came up the trail to Montana from Texas with the long-horned herds which were to stock the northern ranges; he punched cows in Montana when there wasn't a fence in the territory; and he married a daughter of Granville Stuart, the famous early-day stockman and Montana pioneer. For more than fifty years he was known to cowmen from Texas to Alberta as "Teddy Blue."

This is his story, as told to Helena Huntington Smith, who says that the book is "all Teddy Blue. My part was to keep out of the way and not mess it up by being literary.... Because the cowboy flourished in the middle of the Victorian age, which is certainly a funny paradox, no realistic picture of him was ever drawn in his own day. Here is a self-portrait by a cowboy which is full and honest." And Teddy Blue himself says, "Other old-timers have told all about stampedes and swimming rivers and what a terrible time we had, but they never put in any of the fun, and fun was at least half of it."

So here it is--the cowboy classic, with the "terrible" times and the "fun" which have entertained readers everywhere. First published in 1939, "We Pointed Them North "has been brought back into print by the University of Oklahoma Press in completely new format, with drawings by Nick Eggenhofer, and with the full, original text.

The Tragedy of the Commodity - Oceans, Fisheries, and Aquaculture (Hardcover): Stefano B. Longon, Rebecca Clausen, Brett Clark The Tragedy of the Commodity - Oceans, Fisheries, and Aquaculture (Hardcover)
Stefano B. Longon, Rebecca Clausen, Brett Clark
R2,504 Discovery Miles 25 040 Shipped within 7 - 11 working days

Although humans have long depended on oceans and aquatic ecosystems for sustenance and trade, only recently has human influence on these resources dramatically increased, transforming and undermining oceanic environments throughout the world. Marine ecosystems are in a crisis that is global in scope, rapid in pace, and colossal in scale. In The Tragedy of the Commodity, sociologists Stefano B. Longo, Rebecca Clausen, and Brett Clark explore the role human influence plays in this crisis, highlighting the social and economic forces that are at the heart of this looming ecological problem. In a critique of the classic theory "the tragedy of the commons"" by ecologist Garrett Hardin, the authors move beyond simplistic explanations - such as unrestrained self-interest or population growth - to argue that it is the commodification of aquatic resources that leads to the depletion of fisheries and the development of environmentally suspect means of aquaculture. To illustrate this argument, the book features two fascinating case studies - the thousand-year history of the bluefin tuna fishery in the Mediterranean and the massive Pacific salmon fishery. Longo, Clausen, and Clark describe how new fishing technologies, transformations in ships and storage capacities, and the expansion of seafood markets combined to alter radically and permanently these crucial ecosystems. In doing so, the authors underscore how the particular organization of social production contributes to ecological degradation and an increase in the pressures placed upon the ocean. The authors highlight the historical, political, economic, and cultural forces that shape how we interact with the larger biophysical world. A path-breaking analysis of overfishing, The Tragedy of the Commodity yields insight into issues such as deforestation, biodiversity loss, pollution, and climate change.

R992 R713 Discovery Miles 7 130 Save R279 (28%) Shipped within 7 - 13 working days

Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource.

Based on the research expertise of leading scientists, "Commercial Fishing: the Wider Ecological Impacts" provides a lively, timely and accessible account of fishing activities and their impacts on marine habitats, biodiversity and species of conservation concern. It covers fishing methods that range from trawling in the Antarctic to fishing with dynamite in the tropics.

The authors show how habitats such as the muddy sea beds of the deep sea, kelp forests and coral reefs are affected by fishing and how birds, mammals, turtles and sea snakes both suffer and benefit from fishing activities. They also look to the future, highlighting ways to make fishing gear 'environmentally friendly' and asking whether marine reserves will improve conservation.

The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important.

This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks.

"Insect Outbreaks Revisited" is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.

R438 R349 Discovery Miles 3 490 Save R89 (20%) Shipped within 7 - 11 working days

The tale of Honeybee Hotel begins over one hundred years ago, with the Astor family and the birth of the iconic Manhattan landmark, the magnificent Waldorf Astoria. In those early days the posh art deco masterpiece had its own rooftop garden for guests to enjoy. Fast-forward to the turn of the twenty-first century, and we meet executive chef David Garcelon, the creative genius behind the idea of restoring the celebrated rooftop garden. His vision included six hives containing some 300,000 honeybees, which would provide a unique flavor for his restaurant's culinary masterpieces. Yet Garcelon's dream was much grander than simply creating a private chefs' garden: he wanted the honeybee garden to serve as a bond among people. Soon the staff of the hotel, the guests, local horticulturists, and beekeeping experts formed a community around the bees and the garden, which not only raised vegetables, herbs, and honey to be served in the hotel but also provided healthy food to the homeless shelter across the street at St. Bartholomew's Church. Through her meticulous research and interviews with culinary glitterati, entomologists, horticulturists, and urban beekeepers, Leslie Day leads us on a unique insider's tour of this little-known aspect of the natural world of New York City. She familiarizes us with the history of the architectural and cultural gem that is the Waldorf and introduces us to the lives of Chef Garcelon and New York City's master beekeeper, Andrew Cote. Day, an urban naturalist and incurable New Yorker, tells us of the garden's development, shares delectable honey-based recipes from the hotel's chefs and mixologist, and relates the fate of the hotel in the wake of the Waldorf's change of ownership. During our journey, we learn quite a bit about apiaries, as well as insect and flower biology, through the lives of the bees that travel freely around the city in search of nectar, pollen, and resin. This absorbing narrative unwraps the heart within the glamour of one of the world's most beloved cities, while assuring us that nature can thrive in the ultimate urban environment when its denizens care enough to foster that connection.

The stat sheet on hemp sounds almost too good to be true: its fibers are among the planet's strongest, its seed oil the most nutritious, and its potential as an energy source vast and untapped. Its one downside? For nearly a century, it's been illegal to grow industrial cannabis in the United States-even though Betsy Ross wove the nation's first flag out of hemp fabric, Thomas Jefferson composed the Declaration of Independence on it, and colonists could pay their taxes with it. But as the prohibition on hemp's psychoactive cousin winds down, one of humanity's longest-utilized plants is about to be reincorporated into the American economy. Get ready for the newest billion-dollar industry. In Hemp Bound: Dispatches from the Front Lines of the Next Agricultural Revolution, bestselling author Doug Fine embarks on a humorous yet rigorous journey to meet the men and women who are testing, researching, and pioneering hemp's applications for the twenty-first century. From Denver, where Fine hitches a ride in a hemp-powered limo; to Asheville, North Carolina, where carbon-negative hempcrete-insulated houses are sparking a mini housing boom; to Manitoba where he raps his knuckles on the hood of a hemp tractor; and finally to the fields of east Colorado, where practical farmers are looking toward hemp to restore their agricultural economy--Fine learns how eminently possible it is for this misunderstood plant to help us end dependence on fossil fuels, heal farm soils damaged after a century of growing monocultures, and bring even more taxable revenue into the economy than its smokable relative. Fine's journey will not only leave you wondering why we ever stopped cultivating this miracle crop, it will fire you up to sow a field of it for yourself, for the nation's economy, and for the planet.

Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

R1,130 Discovery Miles 11 300 Shipped within 7 - 12 working days

The pig is one of the earliest domesticated animals and plays an integral part in a number of peasant economies in the tropics, for example in Oceania and Southeast Asia. In several African countries and others such as Thailand, increasingly intensive pig production has played a significant role in the overall economic growth and the feeding of an expanding urgan population. Furthermore, although in some circumstances pigs do compete with humans for food resources, they are also very versatile at utilizing byproducts and wastes that are not suitable for human consumption. There is therefore considerable potential for developing pig production in the tropics, and this book provides an accessible guide to the subject for students, farmers and advisory workers. It is translated from an original French edition compiled by the Institut d'Elevage et de Medecine Veterinaire des Pays Tropicaux."

Thanks to breakthroughs in production and food science, agribusiness has been able to devise new ways to grow more food and get it more places more quickly. There is no shortage of news items on hundreds of thousands of hybrid poultry - each animal genetically identical to the next - packed together in megabarns, grown out in a matter of months, then slaughtered, processed and shipped to the other side of the globe. Less well known are the deadly pathogens mutating in, and emerging out of, these specialized agro-environments. In fact, many of the most dangerous new diseases in humans can be traced back to such food systems, among them Campylobacter, Nipah virus, Q fever, hepatitis E, and a variety of novel influenza variants.Agribusiness has known for decades that packing thousands of birds or livestock together results in a monoculture that selects for such disease. But market economics doesn't punish the companies for growing Big Flu - it punishes animals, the environment, consumers, and contract farmers. Alongside growing profits, diseases are permitted to emerge, evolve, and spread with little check. "That is," writes evolutionary biologist Rob Wallace, "it pays to produce a pathogen that could kill a billion people."In Big Farms Make Big Flu, a collection of dispatches by turns harrowing and thought-provoking, Wallace tracks the ways influenza and other pathogens emerge from an agriculture controlled by multinational corporations. Wallace details, with a precise and radical wit, the latest in the science of agricultural epidemiology, while at the same time juxtaposing ghastly phenomena such as attempts at producing featherless chickens, microbial time travel, and neoliberal Ebola. Wallace also offers sensible alternatives to lethal agribusiness. Some, such as farming cooperatives, integrated pathogen management, and mixed crop-livestock systems, are already in practice off the agribusiness grid.While many books cover facets of food or outbreaks, Wallace's collection appears the first to explore infectious disease, agriculture, economics and the nature of science together. Big Farms Make Big Flu integrates the political economies of disease and science to derive a new understanding of the evolution of infections. Highly capitalized agriculture may be farming pathogens as much as chickens or corn.

This book comprehensively describes biological phenomena, adaptation mechanisms, and strategies of living organisms to survive under extremely cold or desiccated conditions at molecular, cellular, and organ levels. It also provides tremendous potential for applications of the findings to a wide variety of industries. The volume consists of three parts: Part 1, Adaptation Mechanisms of Cold, and Part 2, Adaptation Mechanisms of Desiccation, collect up-to-date research on mechanisms and strategies of living organisms such as sleeping chironomids, polar marine fishes, hibernating mammals, bryophytes, dormant seeds, and boreal plants to survive under extreme cold and desiccated conditions at molecular, cellular, and organ levels. Part 3, Application Technologies from Laboratory to Society, covers various applications to a wide variety of industries such as the medical, food, and agricultural and life science industries. For example, biological knowledge of how plants and animals survive under cold, drought, and desiccated conditions may provide a hint on how we can improve crop production in a very fragile environment in global climate change. Unique molecules that protect cells during desiccation and freezing such as trehalose and antifreeze protein (AFP) have potential for use to preserve cells, tissues, and organs for the long term under very stable conditions. In addition, the current progress of supercooling technology of cells may lead us to solve problems of cellular high sensitivity to freezing injury, which will dramatically improve the usability of these cells. Furthermore, knowledge of water substitution and glass formation as major mechanisms for formulation designs and new drying technologies will contribute to the development of food preservation and drug delivery systems under dry conditions. Written by contributors who have been conducting cutting-edge science in related fields, this title is recommended to a wide variety of readers who are interested in learning from such organisms their strategies, mechanisms, and applications, and it will inspire researchers in various disciplines.

R2,025 Discovery Miles 20 250 Shipped within 7 - 12 working days

Egypt is a country of tremendous land resources but limited water resources The area of cultivated land is only 3.2% of the gross area. The river Nile is the main sources of water. In the recent years the Governement established large-scale agricultural projects in light of food security related to the population growth. Expansion of irrigated agriculture has to be predomantly relalized bt increasing the water use efficiency. In Egypt, the dominant irrigation method is surface irrigation, which covers approximately 83% of the irrigated areas. Surface irrigation or gravity methods are generally characterized by a low efficiency. One opportunity to increase the efficiency is to convert surface irrigation to modern irrigation systems, which are generaly highly expensive for a country like Egypt. Another option to increase the efficiency of surface irrigation systems is to convert the traditional irrigation method based on continuous flow to surge flow irrigation. Surge flow irrigation is the intermittent application of water to furrows in a series of relatively short on and off time periods. This study has been carried out to demonstrate the applicability of surge flow irrigation for water saving under the short field conditions that prevail in Egypt. The results indicate that surge flow irrigation is an effective irrigation method to save water and to increase crop production.

The field of medicinal/aromatic plant breeding is growing and changing?this resource will help you stay up to date!
In this essential book, researchers from large and small laboratories and institutions throughout Europe and the Mediterranean region explore recent developments in the selection and breeding of aromatic and medicinal plants. They take varied approaches?from traditional breeding to the use of molecular markers?and complement them with up-to-date information on biodiversity and resource conservation.
"From the editors: ?It is widely recognized that a strategy of conservation through use, ? by which plant collection via wild harvesting is replaced by controlled cultivation, is the best way forward if we are to balance human demands with the necessary conservation of the biodiversity represented by these species. That provides one major driving force for research in this field. Another concerns the very real need for improving the quality control of products on the market, both to satisfy consumer demand and to conform with the (justifiably) increasing requirements for standardization and precise identification of the composition of the plant materials being sold for human use. We hope that this volume will give readers a taste of the exciting developments in the field.?"
Breeding Research on Aromatic and Medicinal Plants examines: breeding for resistance and abiotic factors manipulating natural product accumulation through genetic engineering biochemical and molecular regulation of essential oil accumulation economic and legal considerations that breeders will encounter the ethical aspects of breeding these plants
