Mate preference in wild and domesticated (game-farm) mallards: II. Pairing success Mate preference in wild and domesticated (game-farm) mallards: II. Pairing success
Experiments were designed to determine whether assortative mating occurs in wild and game-farm mallard strains (Anas platyrhynchos). Mallard males of either strain raised with females of their own strain courted females of their own strain more than females of the opposite strain, and these males were only successful in pairing with females of their own strain. Males raised with females...

Classification of wetlands and deepwater habitats of the United States Classification of wetlands and deepwater habitats of the United States
This classification, to be used in a new inventory of wetlands and deepwater habitats of the United States, is intended to describe ecological taxa, arrange them in a system useful to resource managers, furnish units for mapping, and provide uniformity of concepts and terms. Wetlands are defined by plants (hydrophytes), soils (hydric soils), and frequency of flooding. Ecologically...

Fall foods of migrant common snipe in North Dakota Fall foods of migrant common snipe in North Dakota
Studies of foods consumed by common snipe (Capella gallinago) during fall migration (Sperry 1940, Erickson 1941, Choate in Tuck 1972, Tuck 1972) have shown that diets vary among habitats. More recently, Fogarty and Arnold (1977) expressed the need for more detailed information on snipe food habits and more refined knowledge of the snipe's range and adaptability to various food situations...

Early imprinting in wild and game-farm mallards (Anas platyrhynchos): Genotype and arousal Early imprinting in wild and game-farm mallards (Anas platyrhynchos): Genotype and arousal
Early imprinting was studied under laboratory conditions in five lines of mallards (Anas platyrhynchos) with different degrees of wildness obtained through pedigreed breeding. Data were analyzed by the least squares method. Wild ducklings imprinted better than game-farm (domesticated) ducklings, and heterosis was demonstrated to exist in imprinting traits. Nonadditive genetic variations...
