Chemical composition of rainbow trout urine following acute hypoxic stress
Rainbow trout (Salmo gairdnerii) were anesthetized with MS-222, catheterized, and introduced into urine collecting chambers. Twenty-four hours after introduction, a 4-hour accumulation of urine was collected to serve as the control. Water flow to the chambers was then discontinued for 30 minutes during which the oxygen content of the water exiting in the chamber dropped from 4.9 to 2.8 mg/l. Follo

Determination of phosphate in natural waters by activation analysis of tungstophosphoric acid
Activation analysis may be used to determine quantitatively traces of phosphate in natural waters. Methods based on the reaction 31P(n,γ)32P are subject to interference by sulfur and chlorine which give rise to 32P through n,p and n,α reactions. If the ratio of phosphorus to sulfur or chlorine is small, as it is in most natural waters, accurate analyses by these methods are difficult to achieve. I

The influence of nitrogen on heterocyst production in blue-green algae
A series of experiments on heterocyst production in Anabaena variabilis provides some strong indirect evidence for the role of heterocysts in nitrogen fixation. Of the algae tested (Anabaena variabilis, A. inaequalis, A. cylindrica, A. flos-aquae, Tolypothrix distorta, Gloeotrichia echinulata, Aphanizomenon flos-aquae, Oscillatoria sp., and Microcystis aeruginosa), only those with heterocysts grew

[Book review] Life histories of North American cardinals, grosbeaks, buntings, towhees, finches, sparrows, and allies
The completion of an ornithological series as important as the Bent Life Histories is an exciting event. Here is a series of 21 volumes, spanning a history of nearly 60 years from inception to completion, containing over 9,500 text pages of information about North American birds, largely the work of one man – who was not professionally an ornithologist. One cannot well review the final number of s

[Book review] A field guide to the birds of New Zealand and outlying islands
This field guide is so closely patterned after the familiar Peterson style that it may best be described in terms of its departures from that style. Color plates are disappointingly few. They depict: Penguin heads, parrots and kingfisher, eight species of ducks, a pigeon and seven species of native songbirds, eight other passerines and two cuckoos, and nine introduced songbirds (eight of which hav
