Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. - Provides detailed information on the biology of different key weed species - Covers weed seed germination and emergence - Presents the factors affecting weed growth and seed production

Book Description
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.

Book Description
Winner of the IENE Project Award 2016. This authoritative volume brings together some of the world’s leading researchers, academics, practitioners and transportation agency personnel to present the current status of the ecological sustainability of the linear infrastructure – primarily road, rail and utility easements – that dissect and fragment landscapes globally. It outlines the potential impacts, demonstrates how this infrastructure is being improved, and how broad ecological principles are applied to mitigate the impact of road networks on wildlife. Research and monitoring is an important aspect of road ecology, encompassing all phases of a transportation project. This book covers research and monitoring to span the entire project continuum – starting with planning and design, through construction and into maintenance and management. It focuses on impacts and solutions for species groups and specific regions, with particular emphasis on the unique challenges facing Asia, South America and Africa. Other key features: Contributions from authors originating from over 25 countries, including from all continents Each chapter summarizes important lessons, and includes lists of further reading and thoroughly up to date references Highlights principles that address key points relevant to all phases in all road projects Explains best-practices based on a number of successful international case studies Chapters are "stand-alone", but they also build upon and complement each other; extensive cross-referencing directs the reader to relevant material elsewhere in the book Handbook of Road Ecology offers a comprehensive summary of approximately 30 years of global efforts to quantify the impacts of roads and traffic and implement effective mitigation. As such, it is essential reading for those involved in the planning, design, assessment and construction of new roads; the management and maintenance of existing roads; and the modifying or retrofitting of existing roads and problem locations. This handbook is an accessible resource for both developed and developing countries, including government transportation agencies, Government environmental/conservation agencies, NGOs, and road funding and donor organisations.
