Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

In Modern Nature,Lynn K. Nyhart traces the emergence of a “biological perspective” in late nineteenth-century Germany that emphasized the dynamic relationships among organisms, and between organisms and their environment. Examining this approach to nature in light of Germany’s fraught urbanization and industrialization, as well the opportunities presented by new and reforming institutions, she argues that rapid social change drew attention to the role of social relationships and physical environments in rendering a society—and nature—whole, functional, and healthy. This quintessentially modern view of nature, Nyhart shows, stood in stark contrast to the standard naturalist’s orientation toward classification. While this new biological perspective would eventually grow into the academic discipline of ecology, Modern Nature locates its roots outside the universities, in a vibrant realm of populist natural history inhabited by taxidermists and zookeepers, schoolteachers and museum reformers, amateur enthusiasts and nature protectionists. Probing the populist beginnings of animal ecology in Germany, Nyhart unites the history of popular natural history with that of elite science in a new way. In doing so, she brings to light a major orientation in late nineteenth-century biology that has long been eclipsed by Darwinism.
