Changes in blood calcium and phosphorus concentrations were
characterized for rainbow trout (Salmo gairdneri) and coho salmon
(Oncorhynchus kisutch) following intense exercise or exposure to
suspended volcanic ash or topsoil. Significant elevations in blood
calcium and phosphorus accompanied exercise-induced acidemia in both
S. qairdneri and O. kisutch. These elevations persisted...
The purpose of the study was to analyze the effect
of experimenter delivered and microcomputer delivered
knowledge of results on the response speed of nonretarded
and mentally retarded public school students. Response
speed was measured for 63 nonretarded students and 63
mentally retarded students. Subjects were randomly
assigned to conditions...

Detection of L-serine and D,L-alanine by juvenile coho salmon (Oncorhynchus kisutch) was measured in a two-choice Y-trough. Threshold concentration for olfactory
detection of L-serine was 10-8 M for zero-age parr, 1O-7 M for yearling parr, 10-5 M for smolts in late April-early May, and 10-6 M for smolts in June....
We examined the diets and weight-length relationships of juvenile bluefish Pomatomus saltatrix from Sandy Hook Bay, New Jersey, during 1981, 1983, and 1984. Diets consisted of a variety of polychaete, crustacean, and fish prey. Opossum shrimp Neomysis americana. sand shrimp Crangon septemspinosa, grass shrimp Palaemonetes vulgar is, bay anchovy Anchoa...
Juvenile red hake Urophycis chuss were collected while they were inhabiting sea scallops Placopecten magellanicus , and the effects of appetite and food availability on prey consumption and growth were examined under laboratory conditions. Fish took increasing amounts of live amphipods Gammarus annulatus with increasing periods of food deprivation up...
Chloride containing fertilizers are used to reduce the severity of take-all root rot of wheat in western Oregon and appear to reduce nitrification in moderately acid soils. Objectives of this study were to determine if nitrification is inhibited by the Cl ion, increasing soil solution ionic strength, or changes in...
