Book Description
Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Book Description
Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i

Book Description
This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.

Book Description
Growing for 100 - the complete year-round guide for the small-scale market grower. Across North America, an agricultural renaissance is unfolding. A growing number of market gardeners are emerging to feed our appetite for organic, regional produce. But most of the available resources on food production are aimed at the backyard or hobby gardener who wants to supplement their family's diet with a few homegrown fruits and vegetables. Targeted at serious growers in every climate zone, Sustainable Market Farming is a comprehensive manual for small-scale farmers raising organic crops sustainably on a few acres. Informed by the author's extensive experience growing a wide variety of fresh, organic vegetables and fruit to feed the approximately one hundred members of Twin Oaks Community in central Virginia, this practical guide provides: Detailed profiles of a full range of crops, addressing sowing, cultivation, rotation, succession, common pests and diseases, and harvest and storage Information about new, efficient techniques, season extension, and disease resistant varieties Farm-specific business skills to help ensure a successful, profitable enterprise Whether you are a beginning market grower or an established enterprise seeking to improve your skills, Sustainable Market Farming is an invaluable resource and a timely book for the maturing local agriculture movement.

Book Description
The multitrophic level approach to ecology addresses the complexity of food webs much more realistically than the traditional focus on simple systems and interactions. Only in the last few decades have ecologists become interested in the nature of more complex systems including tritrophic interactions between plants, herbivores and natural enemies. Plants may directly influence the behaviour of their herbivores' natural enemies, ecological interactions between two species are often indirectly mediated by a third species, landscape structure directly affects local tritrophic interactions and below-ground food webs are vital to above-ground organisms. The relative importance of top-down effects (control by predators) and bottom-up effects (control by resources) must also be determined. These interactions are explored in this exciting volume by expert researchers from a variety of ecological fields. This book provides a much-needed synthesis of multitrophic level interactions and serves as a guide for future research for ecologists of all descriptions.

Book Description
Building on our knowledge of soil ecology under natural, undisturbed conditions, Soil Tillage in Agroecosystems focuses on how cultivation affects soil and the soil environment. In particular, it highlights how methods of soil tillage can influence soil structure, soil chemical processes, soil borne pathogens, and pest species. Covering the aspects of soil tillage on different taxa, the book concludes with a synthesis of the role of soil tillage in securing a sustainable agricultural environment. It provides the scientific basis for choosing different tillage options to achieve the best possible sustainable base for long-lasting agricultural production.
