Environmental contaminants in eggs of California least terns (Sterna antillarum browni)
A severe decline in the coastal breeding population of California least terns (Sterna antillarum browni) in California and Baja California (U.S. Fish Wildl. Serv. 1980) prompted both State and Federal governments to designate it an endangered species in 1970 (Massey 1974). Significant losses of nesting and feeding habitat have contributed greatly to the decline of this subspecies (Massey 1974; Atw

Distribution of phytobenthos in the Yakima River basin, Washington, in relation to geology, land use and other environmental factors
Benthic-algal distributions in the Yakima River, Washington, basin were, examined in relation to geology, land use, water chemistry, and stream habitat using indicator-species classification (TWINSPAN) and canonical correspondence analysis (CCA). Algal assemblages identified byTWINSPAN were each associated with a narrow range of water-quality conditions. In the Cascade geologic province, where tim

Effect of predation by Sacramento squawfish (Ptychocheilus grandis) on habitat choice of California roach (Lavinia symmetricus) and rainbow trout (Oncorhynchus mykiss) in artificial streams
We studied the effects of predatory Sacramento squawfish (Ptychocheilus grandis) on habitat choice of juvenile California roach (Lavinia symmetricus), adult roach, and juvenile rainbow trout (Oncorhynchus mykiss) in artificial streams. In single-prey trials, the proportion of fish found in pool habitat declined in the presence of squawfish for juvenile roach (from 0.55 to 0.00), adult roach (from

Tertiary volcanic rocks from the southern Pannonian Basin, Croatia
The Tertiary volcanic rocks of the southern part of the Pannonian Basin are related to a sequence of tectonic events that occurred along the northern margin of the Dinarides when subduction ceased and after uplift of the region in middle Eocene time. The oldest rocks are andesites and dacites erupted during an Egerian to Eggenburgian marine transpression phase. In early Miocene time (about 17 Ma),

Land subsidence in drained histosols and highly organic mineral soils of California
This study was conducted to determine historical trends in subsidence in the Sacramento-San Joaquin Delta and their environmental controls. In the western Delta, average subsidence rates were 2.3 cm yr-1 from 1910 to 1.5 cm yr-1 from 1952 to 1988. Spatially variability in subsidence was correlated with organic matter content of the soil which in turn was related to the depositional and drainage hi

Transport of reacting solutes in rivers and streams
In this chapter we discuss the major processes affecting solutes in rivers and streams. Here a solute is generally defined as any substance or entity that is transported downstream by the flowing waters. Under this definition, solutes may be pollutants, such as pesticides and hydrocarbons, or naturally occurring substances such as dissolved gases, nutrients, and trace elements. Study of the proces

Ground-water conditions in Utah, spring of 1995
This is the thirty-second in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Department of Natural Resources, Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions.This report, like the others in the series, contai
