For ages 6-12. The life cycle of a wolf revolves around the complex family structure of the pack. In this book, children will learn about the intricacies of pack life and the ways in which each stage of a wolf pup's development determines its future in the family group. Photographs and illustrations of these majestic animals illuminate topics such as: different types of wolves; the preparation of a birthing den; a pup's introduction to the hunt; challenges to pack structure; dangers to wolves in the wild.

From the third international workshop on the subject (U. of Florence, 1997), come 18 papers reviewing the issue of alien crayfish decimating the relatively few native species in European freshwater environments. In a historical and taxonomic context, the initial paper explains why such homogenizatio

Integrating research into freshwater biodiversity and the role of keystone species, this fascinating book presents freshwater crayfish as representatives of human-exacerbated threats to biodiversity and conservation. It uses examples from these and other large decapod invertebrates to explore how communities function and are controlled, alongside the implications of human demands and conflicts over limited resources, notably the severe impacts on biodiversity. The discussion is structured around three key topics – the present situation of crayfish in world freshwater ecosystems, the applications of science to conservation management and knowledge transfer for successful crayfish management. It outlines the historic exploitation of crayfish, addressing the problems caused by invasive alien forms and explaining the importance of correct identification when dealing with conservation issues. Offering a global perspective on freshwater systems, the book ultimately highlights how the conservation of such large and long-lived species will help protect ecosystem quality in the future.

"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

"This book represents the most in-depth treatment of crayfishes for the state of Alabama to date. Alabama is currently known to host 99 species of crayfishes. The findings in this book are based on more than 9,000 records gathered from across the entire state. The authors collected specimens and data from all of Alabama's major and minor waterways and lakes, as well as specialized habitats such as burrows, roadside ditches, marshes, swamps, and temporary autumnal ponds. They visited all the major museums with holdings of crayfish specimens from Alabama, yielding a list of historical records including 4,259 specimen lots from approximately 2,200 unique locations. These records were used to build a database containing all available specimen metadata, including, but not limited to: species identification, number of individuals collected, location, date of collection, names of collectors, who identified the specimens, and the museum in which they are stored. Field work was conducted over a 14-year period during which a total of 4,487 specimen lots were collected and added to the database from approximately 2,600 unique locations sampled across Alabama. Prior to this book, no single comprehensive book or reference has ever been published on the crayfishes of Alabama. This book compiles 166 years of crayfish distributional and biological data for the 99 known Alabama species. It begins with chapters on the physiography and waterways of Alabama. One chapter discusses the general distributional patterns and habitat associations of Alabama crayfishes. Subsequent chapters discuss crayfish biology, ecology, conservation, and anatomy. Detailed species accounts include descriptions of morphological characters, life color, maximum size, comparative species, distribution and habitat, biology, crayfish associates, and conservation status. Color photographs, morphological plates, and dot maps showing distributions are included for each species; for many species, multiple color photos demonstrate the known color variations within each species. An illustrated key is provided to guide the identification of all 99 species. As the most up-to-date and comprehensive source of information on Alabama crayfishes to date, "Crayfishes of Alabama" provides a new perspective on Alabama's unique place as a biodiversity hotspot. It will be of lasting value to aquatic biologists and ecologists throughout the Southeast and crayfish biologists around the world, as well as of interest to natural resource managers, aquaculture farmers, and naturalists"--
