The use of kestrels in toxicology The use of kestrels in toxicology
Various species of kestrels have become important bioindicators of environmental quality and test species for comparative toxicology in captivity. At least 7 species of kestrels have been used to document the presence of environmental contamination primarily organochlorines and metals, in at least 15 countries. Captive kestrels have been used in studies involving a wide variety of...

Trends in American kestrel counts from the North American Breeding Bird Survey Trends in American kestrel counts from the North American Breeding Bird Survey
A 15-year summary of the BBS data suggests that continental numbers of American Kestrels have increased during 1966-1979. According to analyses of physiographic and state/province strata, some areas are largely responsible for the increase in the U.S. and southern Canada and that only in Illinois and Arkansas have kestrels declined. BBS data are too few in Florida to detect trends...

Use of slope, aspect, and elevation maps derived from digital elevation model data in making soil surveys Use of slope, aspect, and elevation maps derived from digital elevation model data in making soil surveys
Maps showing different classes of slope, aspect, and elevation were developed from U.S. Geological Survey digital elevation model data. The classes were displayed on clear Mylar at 1:24 000-scale and registered with topographic maps and orthophotos. The maps were used with aerial photographs, topographic maps, and other resource data to determine their value in making order-three soil...
