Weeds are problematic both in agricultural and non-agricultural areas so that they potentially cause economic losses. Weed interference in crops also date back to the beginning of agriculture and they have been able to persist, in spite of long term control operations. They are able to adapt and survive in the environment due to their specific characteristics. Thus, to control weeds efficiently knowledge of weed biology, in particular their survival mechanisms, ecological responses and interactions, is of important value in weed management systems. "Weeds and their Ecological Functions" provides information on weeds functional behaviours in their cultivations including weed seed dormancy, germination and seedling emergence, examples of beneficial and detrimental interactions between weeds and other organisms, weed behaviours in perennial crops and response of weeds to cover crops. This information is useful for students and weed scientists to analyse some of the functional behaviour of weeds and to develop integrated weed management systems.

Weeds are successful plants, but on their own terms. Looking at weeds from an ecological viewpoint, emphasising the way in which one species interacts with others, the authors show that weeds are questionable mainly in that they are out-of-place.

The Wild Wisdom of Weeds is the only book on foraging and edible weeds to focus on the thirteen weeds found all over the world, each of which represents a complete food source and extensive medical pharmacy and first-aid kit. More than just a field guide to wild edibles, it is a global plan for human survival. When Katrina Blair was eleven she had a life-changing experience where wild plants spoke to her, beckoning her to become a champion of their cause. Since then she has spent months on end taking walkabouts in the wild, eating nothing but what she forages, and has become a wild-foods advocate, community activist, gardener, and chef, teaching and presenting internationally about foraging and the healthful lifestyle it promotes. Katrina Blair’s philosophy in The Wild Wisdom of Weeds is sobering, realistic, and ultimately optimistic. If we can open our eyes to see the wisdom found in these weeds right under our noses, instead of trying to eradicate an “invasive,” we will achieve true food security. The Wild Wisdom of Weeds is about healing ourselves both in body and in spirit, in an age where technology, commodity agriculture, and processed foods dictate the terms of our intelligence. But if we can become familiar with these thirteen edible survival weeds found all over the world, we will never go hungry, and we will become closer to our own wild human instincts—all the while enjoying the freshest, wildest, and most nutritious food there is. For free! The thirteen plants found growing in every region across the world are: dandelion, mallow, purslane, plantain, thistle, amaranth, dock, mustard, grass, chickweed, clover, lambsquarter, and knotweed. These special plants contribute to the regeneration of the earth while supporting the survival of our human species; they grow everywhere where human civilization exists, from the hottest deserts to the Arctic Circle, following the path of human disturbance. Indeed, the more humans disturb the earth and put our food supply at risk, the more these thirteen plants proliferate. It’s a survival plan for the ages. Including over one hundred unique recipes, Katrina Blair’s book teaches us how to prepare these wild plants from root to seed in soups, salads, slaws, crackers, pestos, seed breads, and seed butters; cereals, green powders, sauerkrauts, smoothies, and milks; first-aid concoctions such as tinctures, teas, salves, and soothers; self-care/beauty products including shampoo, mouthwash, toothpaste (and brush), face masks; and a lot more. Whether readers are based at home or traveling, this book aims to empower individuals to maintain a state of optimal health with minimal cost and effort.

Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.

The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.

This comprehensive guide to wetland weeds covers both native and introduced species, ranging from minor or localised environmental problems to those that should not be tolerated in any situation. The author takes a pragmatic approach to weed control, recognising that some weeds may not be possible to eradicate, and emphasising the need to assess the extent and future potential of any infestation before taking action. Weed control should be planned in the context of the overall management goals for any type of wetland, the types of habitat weeds provide or overrun, and whether they can be replaced successfully with more appropriate plants. A range of strategies for controlling wetland weeds are considered, from containment actions to prevent the development of a soil seed bank to physical removal, and biological approaches from biocontrol to shading, overplanting and use of turbidity. The widespread use of chemical controls is also discussed, with the warning that these are often only a short-term cure and can cause more harm to aquatic ecosystems than the weeds they are holding at bay. More than 130 species of established weeds are included with information on their origins, nutrient responses, environmental effects, habitat values, prospects for containment or eradication, and even culinary uses. Other sections look at native plants as weeds, including a number of species of uncertain origins, and potential weeds still being legally sold through the aquarium and nursery trades.
