This is a contribution to the conservation of members of the family Cambaridae. This book is focused on the evaluation of geographic changes caused by landscape scale and land use change that has impacted the ecology of North American crayfish species. The book includes chapters on geographic distributions, conservation strategies, and effects of contaminants on crayfish structure and function. Contributors include a variety of students associated with the Editor, as well as original contributions from the Editor's colleagues. From the conceptual frameworks to the case studies, Geographic Distribution, Ecological Impact, and Conservation Strategies for North American Crayfish will provide important considerations to assist in the conservation and protection of crayfish, with emphasis on stressors and actions necessary to protect and restore crayfish habitats and populations. This book is necessary for environmental and natural resource managers, researchers, and governmental agencies tasked with the protection, restoration, and management of wildlife populations.
