Comparative acute oral toxicity of pesticides to six species of birds
Acute oral LD50 values were determined for 16 common pesticides on mallard ducks (Anas platyrhynchos), ring-necked pheasants (Phasianus colchicus), chukar partridges (Alectoris graeca), coturnix quail (Coturnix coturnix japonica), common pigeons (Columba livia), and house sparrows (Passer domesticus). Analyses of the data revealed that (1) the average sensitivity of any one species to the 16 pesti

Rapid separation of polychlorinated biphenyls from DDT and its analogues on silica gel
Polychlorinated biphenyls (PCB's), which are used in industry worldwide (i), have been found as residues in numerous wildlife species (2-7). Because of the similarity in chemical characteristics, PCB compounds interfere with gas liquid chromatographic (GLC) analysis of certain chlorinated hydrocarbon insecticides (8). In the present study, we sought a rapid microanalytical procedure for separation

Application of remote sensing techniques for appraising changes in wildlife habitat
An attempt was made to investigate the potential of airborne, multispectral, line scanner data acquisition and computer-implemented automatic recognition techniques for providing useful information about waterfowl breeding habitat in North Dakota. The spectral characteristics of the components of a landscape containing waterfowl habitat can be detected with airborne scanners. By analyzing these sp

Biology of larval sea lampreys (Petromyzon marinus) of the 1960 year class, isolated in the Big Garlic River, Michigan, 1960-65
The early life history of the sea lamprey, from hatching to the first capture of metamorphosed individuals, is described from observations on a known-age population isolated in a tributary of southern Lake Superior. The population had its origin in the spring of 1960, when 722 sea lampreys nearing spawning condition were introduced into the Big Garlic River, Marquette County, Michigan, a stream th

Classification of natural ponds and lakes in the glaciated prairie region
The wetland classification system for the United States adopted by the Bureau of Sport Fisheries and Wildlife in 1953 is described by Martin et al (1953) and by Shaw and Fredine (1956). That classification has been followed by many biologists in recent years and is especially useful in categorizing in a general manner the wetlands throughout the country over a span of years. It has become appare
