This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.

Written by and for scholars, planners, and policymakers, Natural Resource Management: The Human Dimension focuses on issues such as the publics role in the decision-making processes of ecosystem management that affect how we use (or abuse) resources. It exposes the reader to a wide variety of applications of Human Dimensions Research, as well as to significant issues involved. One of the greatest needs in natural resource management is for a deeper understanding of the intricate relationship between humans and the natural environment. Human Dimensions Research, an interdisciplinary field involving a broad variety of social science approaches, seeks to fill this need by providing multidimensional assessments of peoples’ behavior, attitudes, and expectations toward natural resources and their uses. Written by and for scholars, planners, and policymakers, Natural Resource Management: The Human Dimension focuses on issues such as the publics role in the decision-making processes of ecosystem management that affect how we use (or abuse) resources. It exposes the reader to a wide variety of applications of Human Dimensions Research, as well as to significant issues involved. At a time when we are either loving our forests and parks to death or paving them over, a better understanding of the problems is critical if we are to create workable policies that will preserve and protect our natural resources
