"The theme of this book is the distribution of the abundance of organisms in space and time. Its core lies in how local births and deaths are tied to emigration and immigration processes, and how environmental variability at different scales affects population dynamics with stochastic processes and spatial structure. The book shows how elementary analytical tools can be used to understand population fluctuations, synchrony, processes un ..."
"Emphasizing the philosophy of uncertainty and the frailties of human psychology when people are confronted with risky situations, this book describes how to conduct a thorough environmental risk assessment. Technical methods are provided to help make assessments more objective and less prone to the biases of those involved in the assessment. Consideration is given to the way in which both subjective beliefs and technical analysis may b ..."
"This book focuses on introduced plant species: their origins and impacts on native vegetation and ecosystems as well as the potential for their control. Aimed at advanced students and land managers concerned with plant community conservation, it includes practical explanations, case studies and an introduction to basic techniques for evaluating the impacts of invasive plants."
"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 ..."
