This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.

During the colonial period, Africans told each other terrifying rumors that Africans who worked for white colonists captured unwary residents and took their blood. In colonial Tanganyika, for example, Africans were said to be captured by these agents of colonialism and hung upside down, their throats cut so their blood drained into huge buckets. In Kampala, the police were said to abduct Africans and keep them in pits, where their blood was sucked. Luise White presents and interprets vampire stories from East and Central Africa as a way of understanding the world as the storytellers did. Using gossip and rumor as historical sources in their own right, she assesses the place of such evidence, oral and written, in historical reconstruction. White conducted more than 130 interviews for this book and did research in Kenya, Uganda, and Zambia. In addition to presenting powerful, vivid stories that Africans told to describe colonial power, the book presents an original epistemological inquiry into the nature of historical truth and memory, and into their relationship to the writing of history.

In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.

Throughout the world, milk and milk products are indispensable components of the food chain. Not only do individual consumers use liquid milk for beverages and cooking, but food manufacturers use vast quantities of milk powder, concentrated milks, butter, and cream as raw materials for further processing. Effective quality assurance in the dairy industry is needed now more than ever. This completely revised and expanded Third Edition of Dairy Microbiology Handbook, comprising both Volume I: Microbiology of Milk and Volume II: Microbiology of Milk Products, updates the discipline’s authoritative text with the latest safety research, guidelines, and information. Pathogens have become a major issue in dairy manufacturing. Escheria coli is a concern, and milk-borne strains of Mycobacterium avium sub-sp. paratuberculosis have been identified as a possible cause of Crohn’s disease. Even little-known parasites like Cryptosporidium have caused disease outbreaks. Consequently, a hazard analysis of selected control/critical points (HACCP) in any manufacturing process has become essential to prevent the contamination of food. This volume also: -Discusses new diagnostic techniques that allow a pathogen to be detected in a retail sample in a matter of hours rather than days -Provides thorough coverage of dairy microbiology principles as well as practical applications -Includes the latest developments in dairy starter cultures and genetic engineering techniques -Offers completely updated standards for Good Manufacturing Practice Quality control and product development managers, microbiologists, dairy scientists, engineers, and graduate students will find the Third Edition of Dairy Microbiology Handbook to be a vital resource.

Invasive plants have an impact on global biodiversity and ecosystem function, and their management is a complex task. The aim of this book is to discuss fundamental questions of invasion ecology, such as why particular communities become more invasible than others, what the mechanisms of exclusion of native species by invaders are, and whether invasion can be predicted. In addition, agricultural practices influencing invasion, the environmental and economic costs of invasion as well as possible management strategies are discussed. Readers will get a unique perspective on invasion ecology through employing general principles of ecology to plant invasions.

Abatement of Environmental Pollutants: Trends and Strategies addresses new technologies and provides strategies for environmental scientists, microbiologists and biotechnologists to help solve problems associated with the treatment of industrial wastewater. The book helps readers solve pollution challenges using microorganisms in bioremediation technologies, including discussions on global technologies that have been adopted for the treatment of industrial wastewater and sections on the lack of proper management. Moreover, limited space, more stringent waste disposal regulations and public consciousness have made the present techniques expensive and impractical. Therefore, there is an urgent need to develop sustainable management technologies for industries and municipalities. To remove the damaging effect of organic pollutants on the environment, various new technologies for their degradation have been recently discovered. - Covers bioremediation of petrochemical pollutants, such as Benzene, Toluene, Xylene, Ethyl Benzene, and phenolic compound - Includes discussions on genetic engineering microbes and their potential in pollution abatement - Contains information on plant growth promoting bacteria and their role in environment management

Animal welfare is attracting increasing interest worldwide, but particularly from those in developed countries, who now have the knowledge and resources to be able to improve the welfare of farm animals. The increased attention given to farm animal welfare in the West derives largely from the fact that the relentless pursuit of ?nancial reward and ef?ciency has led to the development of intensive animal production systems that disturb the conscience of many consumers. In developing countries, human survival is still a daily uncertainty, so that provision for animal welfare has to be balanced against human welfare. Welfare is usually provided for only if it supports the output of the animal, be it food, work, clothing, sport or companionship. In reality there are resources for all if they are properly husbanded in both developing and developed countries. The inequitable division of the world’s riches creates physical and psychological poverty for humans and animals alike in many sectors of the world. Livestock are the world’s biggest land user (FAO, 2002) and the population is increasing rapidly to meet the need of an expanding human population. Populations of farm animals managed by humans are therefore incre- ing worldwide, and in some regions there is a tendency to allocate fewer resources, such as labour, to each animal with potentially adverse consequences on the a- mals’ welfare.
