A century ago, many people had given up on the wood duck, dooming it to extinction along with the passenger pigeon and Carolina parakeet. Today, it’s one of the most familiar and most harvested ducks in the eastern half of the country, and one of America’s great conservation success stories. In With Wings Extended, Minnesota conservationist Greg Hoch introduces readers to a duck they probably recognize but may not know well. This book shows how almost anyone can get involved in conservation and do something for wildlife beyond writing checks to conservation organizations. Hoch illustrates the complexities of wildlife and habitat management that landowners as well as state and federal wildlife agencies deal with on a daily basis, and takes readers through the life stages of what is largely considered the most beautiful duck in the world. In this fascinating and practical read, Hoch blends the historical literature about the species with modern science, and also shows how our views of conservation have changed over the last century.

Thoroughly updated, with an inviting new design, the Second Edition offers the most current and accessible coverage of essential biological concepts and their applications, principles of resource management and conservation, and contemporary and public policy issues affecting today’s scientists and resources.

This book integrates the science of wildlife and fisheries. Updates include coverage of geographic information systems and biotelemetry; preferred structures for fish aging; information on diseases such as chronic wasting disease, avian flu, West Nile virus, viral haemorrhagic septicemia, and whirling disease.

Discrete Mathematics with Ducks, Second Edition is a gentle introduction for students who find the proofs and abstractions of mathematics challenging. At the same time, it provides stimulating material that instructors can use for more advanced students. The first edition was widely well received, with its whimsical writing style and numerous exercises and materials that engaged students at all levels. The new, expanded edition continues to facilitate effective and active learning. It is designed to help students learn about discrete mathematics through problem-based activities. These are created to inspire students to understand mathematics by actively practicing and doing, which helps students better retain what they’ve learned. As such, each chapter contains a mixture of discovery-based activities, projects, expository text, in-class exercises, and homework problems. The author’s lively and friendly writing style is appealing to both instructors and students alike and encourages readers to learn. The book’s light-hearted approach to the subject is a guiding principle and helps students learn mathematical abstraction. Features: The book’s Try This! sections encourage students to construct components of discussed concepts, theorems, and proofs Provided sets of discovery problems and illustrative examples reinforce learning Bonus sections can be used by instructors as part of their regular curriculum, for projects, or for further study

Small, noisy and colourful, the Teal is a familiar duck throughout the wetlands and waterways Europe and Asia. Once hunted extensively for the pot, its numbers have recovered and it is now one of our commonest species of waterfowl. A flagship species for wetland conservation, the Teal is also an excellent model species for ecological research, and this forms the spine of this new Poyser monograph. The Teal looks at distribution and trends in numbers, foraging ecology, breeding behaviour), population dynamics, management and conservation of teal, looking at both the Eurasian Common Teal and its North American equivalent, the Green-winged Teal (which until relatively recently was considered to be the same species). The book provides a scientifically robust account on which wetland managers, research scientists and the ornithological community may rely, with wider implicatons for the conservation and management of other waterfowl, and for ecological research in general.
