Beschreibungen

Commensal rodents pose health risks and cause substantial damage to property and food supplies. Rats have also invaded islands and pose a serious threat to native wildlife, particularly raptors and seabirds. Estimates of total damage from introduced rats range into the billions of dollars in developed countries. This book aims to provide a state-of-the-art overview of the scientific advancements in the assessment of exposure, effects and risks that currently used rodenticides may pose to non-target organisms in the environment, along with practical guidance for characterization of hazards. This will be discussed in relation to their efficacy, and the societal needs for rodent control, and discussion of  risk mitigation and development of alternatives. The flow in the book is planned as: a.    introduction and setting the scene b.    problem description (risks and effects on non-targets and secondary poisoning, development of resistance) c.  ;  alternatives, regulation and risk mitigation d.    conclusions and recommendations

Anticoagulant rodenticides and wildlife: concluding remarks.<p></p>
Commensal rodents consume and spoil crops and food supplies, cause  property damage and can be vectors for disease. Rats have also invaded islands and can pose a serious threat to native wildlife, particularly seabirds. Estimates of rodent damage range into the billions of dollars in developed countries. In southern Asia, rodents are estimated to consume or destroy annually sufficient rice to feed 50 million people. The predominant control method for pest rodents in most countries is  anticoagulant rodenticides, which are antagonists of vitamin K metabolism that prevent blood-clotting and cause fatal haemorrhage. This mode of toxicity is common to all vertebrates because of their shared blood clotting mechanism, so anticoagulants pose a potential risk to a wide range of non-target species. This is well recognised and anticoagulants fail regulatory environmental risk assessments in many jurisdictions. Nonetheless, the compounds continue to be heavily used because of the societal need for rodent control and the limited availability of safer alternatives.  As a result, exposure of non-target species is commonplace throughout the world and reflects the extensive use, persistence and bioaccumulation potential of many of these compounds. The consequences of such exposure, in terms of effects on wildlife populations, remain uncertain and the subject of much research, debate and controversy.  Accordingly, there is a  significant and ongoing need for integrated assessment of the threats to wildlife from anticoagulant rodenticides, combined with development of governance, mitigation measures and development of alternatives. This book provides a state-of-the-art overview of the scientific advancements in the assessment of exposure, effects and risks that currently used rodenticides may pose to non-target organisms in the environment. This is discussed in relation to their efficacy, and the societal needs for rodent control, and risk mitigation and development of alternatives.<p></p>
This book provides an in-depth yet broad overview on the risks that rodenticides may pose to wildlife, ranging from the biochemical and pharmacokinetic level to ecological field observations affecting secondary exposure Dedicated chapters focus on alternative method for rodent control, including Integrated Pest Management, and on the challenge of development of resistance, with potential implications for their regulation and risk mitigation Consideration of how to detect non-target? rodenticide poisoning in wildlife in the field, and chapters that outline how ecological, landscape and variation in control practices affect exposure and poisoning, make this book not just a scientific overview, but a reference text and a source of practical guidance to scientists, users and even interested members of the public
