Mapping wetlands on beaver flowages with 35-mm photography
R.E. Kirby
1976, Canadian Field-Naturalist (90) 423-431
Beaver flowages and associated wetlands on the Chippewa National Forest, north-central Minnesota, were photographed from the ground and from the open side window of a small high-wing monoplane. The 35-mm High Speed Ektachrome transparencies obtained were used to map the cover-type associations visible on the aerial photographs. Nearly vertical aerial...
Mathematical models for non-parametric inferences from line transect data
K.P. Burnham, David R. Anderson
1976, Biometrics (32) 325-336
A general mathematical theory of line transects is developed which supplies a framework for nonparametric density estimation based on either right angle or sighting distances. The probability of observing a point given its right angle distance (y) from the line is generalized to an arbitrary function g(y). Given only...

1976, Special Scientific Report - Wildlife 200
Data from Bureau of Biological Survey and U.S. Fish and Wildlife Service reports show an overall increase in the number of birds and mammals imported from 1900 to 1972. The trend was interrupted by World War I, the economic depression of the 1930's, and World War II. Data...
Behavior of trace elements during magmatic processes - A summary of theoretical models and their applications
Joseph G. Arth
1976, Journal of Research of the U.S. Geological Survey (4) 41-47
Progress in understanding the behavior of trace elements during the processes that produce igneous rocks has been made possible by the parallel development of theoretical models to describe that behavior and analytical techniques that permit precise measurement of trace-element concentrations in igneous rocks and minerals. The result of this progress...

A probabilistic estimate of maximum acceleration in rock in the contiguous United States
Sylvester Theodore Algermissen, David M. Perkins
1976, Open-File Report 76-416
This paper presents a probabilistic estimate of the maximum ground acceleration to be expected from earthquakes occurring in the contiguous United States. It is based primarily upon the historic seismic record which ranges from very incomplete before 1930 to moderately complete after 1960. Geologic data, primarily distribution of faults, have...
