Recovery of benthic-invertebrate communities in the White River near Indianapolis, Indiana, USA, following implementation of advanced treatment of municipal wastewater Recovery of benthic-invertebrate communities in the White River near Indianapolis, Indiana, USA, following implementation of advanced treatment of municipal wastewater

The City of Indianapolis, Indiana, USA, completed construction of advanced-wastewater-treatment systems to enlarge and upgrade existing secondary-treatment processes at the City’s two municipal wastewater-treatment plants in 1983. These plants discharge their effluent to the White River. A study was begun in 1981 to evaluate the effects of municipal wastewater on the quality of the White...

Mechanisms and function of school formation in subyearling American shad (Alosa sapidissima) Mechanisms and function of school formation in subyearling American shad (Alosa sapidissima)

Summary The behavioural repertoire of subyearling American shad (Alosa sapidissima) was studied in the laboratory to examine pathways leading to Aggregation and School formation at various group sizes (3–100 fish per 500-liter tank). Three hypotheses were tested: (1) schooling is the dominant behavioural activity of subyearling American shad, (2) development and maintenance of cohesive...

Mid-Mesozoic (Mid-Jurassic to Early Cretaceous) evolution of the Georges Bank Basin, U.S. North Atlantic outer continental shelf: Sedimentology of the Conoco 145-1 well Mid-Mesozoic (Mid-Jurassic to Early Cretaceous) evolution of the Georges Bank Basin, U.S. North Atlantic outer continental shelf: Sedimentology of the Conoco 145-1 well

The Conoco 145-1 exploratory well, located in the southeastern portion of the Georges Bank Basin, was drilled to a total depth of 4303 m below the sea floor. The oldest sedimentary rocks sampled are of Middle Jurassic age (Late Bathonian-Callovian). A dolomite-limestone-evaporite sequence dominates the section below 3917 m; limestone is the predominant lithology in the intervals of 3271...

Hormonal control of sulfate uptake by bronchial cartilage of coho salmon: Role of IGF-I Hormonal control of sulfate uptake by bronchial cartilage of coho salmon: Role of IGF-I

The direct hormonal control of sulfate uptake by cartilage matrix of coho salmon was examined by exposing branchial cartilage to 1 μCi · ml−1 35SO4 for 48 hours at 15°C in a defined medium. Sulfate uptake occurred primarily in cartilage (rather than bone) and the amount of specific uptake was similar in epibranchial and ceratobranchial cartilages. Intact and hypophysectomized coho salmon...
