Summary appraisals of the nation's ground-water resources – Souris-Red-Rainy region
A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and the Rainy River within Minnesota. The region includes 59,645 square mi

Rapid method for determining concentrations of Bayer 73 in water during lampricide treatments
Two simple, rapid, sensitive methods were developed for determining the concentration of the lampricide 2',5-dichloro-4'-nitrosalicylanilide (Bayer 73) in stream water. Bayer 73 was extracted from acidified water samples with chloroform and then hydrolyzed to 2-chloro-4-nitroaniline (CNA) with either acid or base. The CNA was diazotized with sodium nitrite, and an azo dye was formed with either N-

Feeding habitat use by colonially-breeding herons, egrets, and ibises in North Carolina
Nine species of herons, egrets, and ibises were followed by airplane from a nesting colony near Beaufort, North Carolina to their feeding sites. Except for Cattle Egrets, which flew exclusively to fields and dumps, the birds flew mainly to saltmarsh habitat. The selection of feeding habitats by Great Egrets and Louisiana Herons was directly related to tidal depth. The Great Egret was the only spec

Seasonal trends in summer diet of the lapland longspur near Barrow Alaska USA
Contents of lapland longspur [Calcarius lapponicus] stomachs and esophagi were sampled near Barrow, Alaska [USA], from May-Aug. in 1969, 1971, 1972 and 1973. Data from stomach contents were corrected for differential digestion of prey items. Longspurs shifted seasonally from larval to adult arthropods and back to larvae, responding to changes in the abundance of these prey items. Seeds were a vita

Effects of dietary addition of vitamins C and D3 on growth and calcium and phosphorus content of pond-cultured channel catfish
Fingerling channel catfish, Ictalurus punctatus, were fed one of three diets: one deficient in vitamin C (ascorbic acid), one deficient in vitamin D3 (cholecalciferol), or one containing both vitamins. Semimonthly from May to September and monthly from September to February, calcium and phosphorus were determined in eviscerated bodies and fat-free skeletons by neutron activation analysis. Body wei
