This book presents information on common-to-rare organisms from around the world that inhabit freshwater habitats. The first six chapters focus on organisms from the very small (e.g., protozoa, zooplankton, and fairy shrimp) to the huge (e.g., hippos, freshwater sharks, and giant turtles), while the last four chapters provide information on aquatic ecosystems (lakes, streams, caves, and wetlands). Included in this last section are the physical nature of the system and how that influences the kinds of animals living there. This unique “nature” book, incorporating information from around the world on both aquatic systems and organisms, is written to attract the interest of a wide group of non-academic readers.

This practical pocket guide, published in association with the Wildlife Trusts, includes more than 190 species of animal and plant that inhabit still-water bodies such as ponds, pools and small lakes in northern Europe. Each species account includes accurate artworks and concise descriptions outlining essential details such as size, habitat, ecology and distribution in Britain and the near Continent. A vast number of species occurs in these habitats, so the guide selectively pictures and describes a good range of fauna and flora that are most likely to be found and identified. Among the fascinating animals featured are freshwater sponges, hydras, water bears, worms, leeches, water snails, dragonflies and damselflies, frogs and toads, bats, fish, birds, and iconic mammals such as the Water Vole and European Otter. The easy-to-follow layouts and illustrations aid quick and precise identification, making the book an indispensable reference in the field as well as in the home and garden.

Protected marine species have populations that are depleted, decreasing, or are at-risk of extinction or local extirpation. As of 2015 The International Union for the Conservation of Nature, a global environmental organization, lists approximately 737 marine species worldwide that are considered at risk of extinction. Many are provided legal protection through national laws requiring research and management measures aimed at recovering and maintaining the species at a sustainable population level. Integral to the policy decision process involving the management and recovery of marine species is the consideration of trade-offs between the economic and ecological costs and benefits of protection. This suggests that economics, at its core the study of trade-offs, has a significant role. In the U.S. a somewhat traditional use of economics in protected species research and management has involved cost minimization or cost-effectiveness analyses to help select or prioritize conservation actions. Economic research has also provided estimates of public non-market benefits of recovering species, which can be used in larger management frameworks such as ecosystem based management and coastal and marine spatial planning. Inherent in much of this research, however, are complex biological and ecological relationships in which varying degrees of scientific uncertainty are present. Addressing this type of uncertainty can affect the economic outcomes related to protected species. For example, recent work suggests that increasing scientific precision in biological sampling and models can greatly affect the magnitude of economic benefits to commercial fisheries, while other research suggests that public non-market benefits of species recovery are sensitive to uncertainty about baseline population estimates. Previous research has illustrated the importance of understanding the biological, ecological, and economic aspects of protected species management and recovery. In this research topic we synthesize current protected marine species economic research and expand the discussion on present and future challenges related to protected species economics. The series of manuscripts brings together an array of prominent researchers and advances our understanding of the ecological and economic aspects of managing and recovering protected marine species.

This illustrated collection offers fascinating insight on restoring the wolf population to the Southern Rockies. Detailed reports by wildlife biologists, geographers, legal and policy experts, and conservationists provide a comprehensive look at not only the ecological imperatives, but also the history, legal framework, and public attitudes affecting the future of wolves.
