Genetic variation in male Yellow-headed Blackbirds from the northern Great Plains Genetic variation in male Yellow-headed Blackbirds from the northern Great Plains
Electrophoretic differences at 15 presumptive loci were used to assess allelic frequencies, heterozygosities, and polymorphism for male Yellow-headed Blackbirds (Xanthocephalus xanthocephalus) collected in east-central Alberta, north-central North Dakota, and east-central South Dakota. Five loci were polymorphic and mean heterozygosities ranged from 0.119 to 0.133. Significant...

Comparison of algorithms for replacing missing data in discriminant analysis Comparison of algorithms for replacing missing data in discriminant analysis
We examined the impact of different methods for replacing missing data in discriminant analyses conducted on randomly generated samples from multivariate normal and non-normal distributions. The probabilities of correct classification were obtained for these discriminant analyses before and after randomly deleting data as well as after deleted data were replaced using: (1) variable means...

Food preferences of spring-migrating blue-winged teal in southwestern Louisiana Food preferences of spring-migrating blue-winged teal in southwestern Louisiana
We studied effects of pair status, molt intensity, and year on food selection by migrating male blue-winged teal (Anas discors) in southwestern Louisiana during springs 1990 and 1991. Diets consisted primarily of animal foods; but plant material, consisting mostly of seeds, comprised as much as 44%. There was no difference in animal food consumption by paired and unpaired males; however...
