Most ecological risk assessments consider the risk to individual organisms or organism-level attributes. From a management perspective, however, risks to population-level attributes and processes are often more relevant.

Most ecological risk assessments consider the risk to individual organisms or organism-level attributes. From a management perspective, however, risks to population-level attributes and processes are often more relevant. Despite many published calls for population risk assessment and the abundance of available scientific research and technical tools assessing risks to populations, risk assessors worldwide still have difficulty determining how population level considerations can be integrated into environmental decision-making. Population-Level Ecological Risk Assessment establishes a framework for goals, methods, and data needs for different assessment applications and for integrating population-level risk assessment into risk management decisions. Beginning with a summary of legal, regulatory, business, and other contexts, the book presents population-level ecological risk assessment as an internationally recognized, science-based tool and offers specific recommendations for using this tool to support environmental management decisions. It gives clear, explicit, operational population assessment definitions and explains the relevance of density dependence, genetics, and spatial considerations, as well as applicable lessons from conservation biology and natural resource management. The authors provide a "tool box" of empirical and modeling methods and describe the general approaches, assumptions, data requirements, strengths, and limitations of each method. They establish a working foundation for designing and conducting population-level ecological risk assessments consistent with North American, European, and Japanese risk management approaches. The book concludes by highlighting key considerations needed to improve the scientific quality and interpretation of assessments. Detailed appendices include examples of population-level assessment approaches applicable to specific environmental management contexts, a modeling case study, and a supplemental r

Toxic chemicals can exert effects on all levels of the biological hierarchy, from cells to organs to organisms to populations to entire ecosystems. However, most risk assessment models express their results in terms of effects on individual organisms, without corresponding information on how populations, groups of species, or whole ecosystems may respond to chemical stressors. Ecological Modeling in Risk Assessment: Chemical Effects on Populations, Ecosystems, and Landscapes takes a new approach by compiling and evaluating models that can be used in assessing risk at the population, ecosystem, and landscape levels. The authors give an overview of the current process of ecological risk assessment for toxic chemicals and of how modeling of populations, ecosystems, and landscapes could improve the status quo. They present a classification of ecological models and explain the differences between population, ecosystem, landscape, and toxicity-extrapolation models. The authors describe the model evaluation process and define evaluation criteria. Finally, the results of the model evaluations are presented in a concise format with recommendations on modeling approaches to use now and develop further. The authors present and evaluate various models on the basis of their realism and complexity, prediction of relevant assessment endpoints, treatment of uncertainty, regulatory acceptance, resource efficiency, and other criteria. They provide models that will improve the ecological relevance of risk assessments and make data collection more cost-effective. Ecological Modeling in Risk Assessment serves as a reference for selecting and applying the best models when performing a risk assessment.

This book introduces various mathematical models used in ecological risk assessment, primarily discussing models used in hazard assessment. The book aims to link ecology and conservation biology with risk assessments, bringing together the knowledge of ecotoxicology and ecology for effective risk assessment. The first part describes population-level assessment in ecological risk assessment. The chapters cover current methodologies for ecological risk assessment, individual-level assessment, population dynamics models for population-level assessment, case studies, mathematical models for population extinctions, the derivation of mean time to extinction (MTE) and their case studies. The second part of the book discusses the mathematical models involved in hazard assessments. It introduces the method of risk assessment using species sensitivity distributions (SSDs), hazard assessment of metals, chemical mixtures using the Michaelis-Menten equation, basic elements of statistics and related topics. Expected readers are risk assessors in governments and public sectors, students and young researchers interested in environmental science. The book is made accessible and easy to follow by beginners in mathematical biology and theoretical ecology.

This edited volume collects population and metapopulation models for a wide variety of species, focusing on the use of models in population-level risk assessment for toxins. Each chapter of Demographic Toxicity describes the application of a population model to one species, with the aim of demonstrating how various life history characteristics of the species are incorporated into the model, how ecotoxicological impacts are modeled, and how the results of the model has been or can be used in risk assessment. The model in each chapter is implemented in RAMAS software, which uses matrix modeling of population dynamics. RAMAS software is believed to be the most powerful tool ever invented for this task.Demographic Toxicity includes a CD that contains a demo version of the program and the data files for each species. The book explains how to use these specific tools for modeling, analysis, and interpretation of data. Demographic Toxicity provides a major review of current knowledge on population dynamics in different species, representing both terrestrial and aquatic environments.

Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

The definitive reference in its field, Ecological Risk Assessment, Second Edition details the latest advances in science and practice. In the fourteen years since the publication of the best-selling first edition, ecological risk assessment (ERA) has moved from the margins into the spotlight. It is now commonly applied to the regulation of chemicals, the remediation of contaminated sites, the monitoring of importation of exotic organisms, the management of watersheds, and other environmental management issues. Delineating the processes for performing an ERA, the book begins by defining the field, then goes on to describe its relationship to other environmental assessment practices and its organizational framework. The book also includes a chapter on ecological epidemiology, which has previously been treated as a type of ERA, but is now recognized as a distinct practice in itself. It explores important concepts in the ERA process including probability, uncertainty, scale, mode of action and multiple causes. Reflecting changes in the field, the book’s scope has been broadened to include discussions of the application of ERA to agents other than chemical contaminants. The multitude of illustrative figures provides a flavor for the diverse practice of ERA. The author has re-organized the material, presenting a unitary process of ERA that is applicable to various problems, scales, and mandates. He keeps the emphasis squarely on providing clear, scientifically sound, and unbiased technical advice on the risks from chemicals and chemical mixtures.
