Nematode parasites of waterfowl (Anseriformes) from western United States Nematode parasites of waterfowl (Anseriformes) from western United States
Thirty-four species of nematodes were found in 415 Anseriformes (Anatidae) of 27 species; 93.7% of birds over 4 weeks old were infected. Data on prevalence, host specificity, age of host, and geographic distribution are given. Infections were more intense in sick birds and birds in poor physical condition. Accidental or abnormal infection was more likely in sick than in normal birds...

Relationships between chemical structure and rat repellency. II. Compounds screened between 1950 and 1960 Relationships between chemical structure and rat repellency. II. Compounds screened between 1950 and 1960
Over 4,600 compounds, chiefly organic types, were evaluated using both a food acceptance test (Part A) and a barrier penetration bioassay (Part B), to correlate relationships between chemical structure and rodent repellency.These chemicals are indexed and classified according to the functional groups present and to the degree of substitution within their molecular structures. The results...

New concepts regarding the production of waterfowl and other game birds in areas of diversified agriculture New concepts regarding the production of waterfowl and other game birds in areas of diversified agriculture
Many concepts regarding breeding ecology of waterfowl and the influences of environmental factors on annual production have changed in the past 20 years. These influences are especially pronounced in the prairie region of central North America where agriculture becomes more intensive each year. The principal task assigned to this Research Center when established in 1965 was to determine...

Habitat management considerations for prairie chickens Habitat management considerations for prairie chickens
Lack of nesting and brood rearing habitat appears to be the universal limiting factor for prairie chickens (Tympanuchus cupido pinnatus) throughout their range. Grasslands are essential to prairie chickens, but vary widely in quality and thus in their ability to support prairie chickens. High-quality habitat is grassland providing residual vegetation averaging about 20 inches in height...
