The original report From the Sierra to the Sea: Ecological History of the San Francisco Bay-Delta Watershed was a product of a three-year effort to develop a landscape level overview of the natural ecological structure, function and organization of the watershed, and the way it had changed over the course of the 19th and 20th centuries. Technical review and contributions from government and water agencies helped produce a collaborative document that provided information on the historical ecological baseline in order to assist in what was envisioned at the time as the most ambitious restoration effort ever undertaken in the United States. We are proud of the fact that the original document is still used as an objective reference, and has provided a foundation and inspiration for similar but more intensively researched localized efforts by others in the Bay-Delta watershed. This 20th anniversary edition contains a new Afterword describing changes to the estuary and its watershed since the report was originally published in 1998.

Examining tissue residues of contaminants in biota reveals the movement of contaminants within organisms and through food chains as well as the context for understanding and quantifying injuries to organisms and their communities. Yet tissue concentrations of some contaminants are especially challenging to interpret and the ability of today’s analytical chemists to provide reliable analytical data of most important environmental contaminants often surpasses the ability of ecotoxicologists to interpret those data. Offering guidance on the ecotoxicologically meaningful interpretation of tissue concentrations, Environmental Contaminants in Biota, Interpreting Tissue Concentrations, Second Edition is updated with current data and new ways of analyzing those data as well as additional contaminants not previously considered. Beginning with a history of wildlife toxicology and data interpretation, chapters cover a wide range of contaminants and their hazardous and lethal concentrations in various animals including DDT, Dioxins, PCBs, and PBDEs in aquatic organisms; methylmurcury, selenium, and trace metals in fishes and aquatic invertebrates; and pharmaceuticals and organic contaminants in marine mammals. The book considers the impact of Polychlorinated Biphenyls, Dibenzo-p-Dioxins and Dibenzofurans, and Polybrominated Diphenyl Ethers; cyclodiene; and other organochlorine pesticides in birds and mammals. Later chapters examine the effects and analysis of lead, cadmium, and radionuclides in biota. With thousands of published research papers reporting tissue concentrations each year, Environmental Contaminants in Biota, Interpreting Tissue Concentrations, Second Edition gives ecotoxicologists the ability to draw actionable value regarding the toxicological consequences of those concentrations and relate tissue concentrations quantitatively to injury: the core of ecotoxicology.

As an integral component of environmental policy, it has become essential to regulate and monitor toxic substances. Past emphasis has been primarily on analytical approaches to the detection of specific, targeted contaminants, thus allowing chemical characterisation. However, toxicity testing or biological assessment is necessary for ecotoxicological evaluation, and this offers marked benefits and advantages that complement chemical analysis. Key issues to be addressed include identification of pertinent tests, reproducibility and robustness of these tests, and cost considerations.This book examines these issues and describes and explains the approaches that have been developed for environmental toxicity evaluations. Advantages, benefits and drawbacks of the strategies and methods are highlighted. Directed equally at ecotoxicologists, industrial chemists, analytical chemists and environmental consultants, this book is written in a way that will prove helpful to both new and experienced practitioners.

This book discusses various freshwater ecosystems and methods used for the purposes of water quality monitoring, including those utilising aquatic macrophytes. Early-established management plans provide the first steps towards sustainable management of aquatic environments. Thus, the methods used for managing aquatic plants, including mechanical or manual harvesting, hand-pulling and biological control are discussed. The removal efficiency of nutrients and of metal by macrophytes is examined, as well as the potential use of these plants in wastewater treatment. This book surveys and critically reviews existing literature regarding the presence of steroid sex hormones in freshwater ecosystems, their sources and potential fate. Discharges from wastewater treatment plants and transport from agricultural operations are also examined. Finally, this book discusses the role of NF-kB inhibitors, an inducible transcription, in marine chemical ecology, as well as its role in biomedicine.

This extensively revised and expanded new edition offers concepts, principles and applied information that relates to the wellbeing of reptiles. As a manual on health and welfare in a similar vein to volumes addressing the sciences of anatomy, behaviour or psychology, this book thoroughly examines the biology of reptile welfare and is about meeting biological needs. The editors, acknowledged experts in their own right, have once again drawn together an extremely impressive international group of contributors. Positive and negative implications of general husbandry and research programs are discussed. In addition to greatly revised original content are nine new chapters offering readers novel insight into: • sensory systems • social behaviour • brain and cognition • controlled deprivation and enrichment • effects of captivity-imposed noise and light disturbance on welfare • spatial and thermal factors• evidential thresholds for species suitability in captivity • record keeping as an aid to captive care • arbitrary husbandry practices and misconceptions The authors have adopted a user-friendly writing style to accommodate a broad readership. Although primarily aimed at academic professionals, this comprehensive volume is fundamentally a biology book that will also inform all involved in captive reptile husbandry. Among others, zoo personnel, herpetologists, veterinarians, lab animal scientists, and expert readers in animal welfare and behavioural studies will benefit from this updated work.
