The global spread of plant species by humans is both a fascinating large scale experiment and, in many cases, a major perturbation to native plant communities. Many of the most destructive weeds today have been intentionally introduced to new environments where they have had unexpected and detrimental impacts. This 2003 book considers the problem of invasive introduced plants from historical, ecological and sociological perspectives. We consider such questions as 'What makes a community invasible?', 'What makes a plant an invader?' and 'Can we restore plant communities after invasion?' Written with advanced students and land managers in mind, this book contains practical explanations, case studies and an introduction to basic techniques for evaluating the impacts of invasive plants. An underlying theme is that experimental and quantitative evaluation of potential problems is necessary, and solutions must consider the evolutionary and ecological constraints acting on species interactions in newly invaded communities.

This is the first comprehensive exploration of why human security is relevant to the Arctic and what achieving it can mean, covering the areas of health of the environment, identity of peoples, supply of traditional foods, community health, economic opportunities, and political stability. The traditional definition of security has already been actively employed in the Arctic region for decades, particularly in relation to natural resource sovereignty issues, but how and why should the human aspect be introduced? What can this region teach us about human security in the wider world? The book reviews the potential threats to security, putting them in an analytical framework and indicating a clear path for solutions.Contributions come from natural, social and humanities scientists, hailing from Canada, Russia, Finland and Norway. Environmental Change and Human Security in the Arctic is an essential resource for policy-makers, community groups, researchers and students working in the field of human security, particularly for those in the Arctic regions.
