Adult female Dusky Canada Geese were studied on the
Copper River Delta, Alaska and in the Willamette Valley,
Oregon during April through July, 1977 to 1979. Objectives
of the research were to: 1) determine the chronology of use
of protein and energy reserves in relation to four periods
of reproduction...
Several aspects of feedback mechanisms associated with surf zone sandbar response have been characterized using bathymetric surveys, sampled approximately monthly over a 16-year period at the Army Corps of Engineers' Field Research Facility (North Carolina). The measured bathymetry was alongshore averaged and modeled by the superposition of two Gaussian-shaped sandbars...

Time and length scales of beach variability have been quantified using 16 years
of beach surveys sampled at the Army Corps of Engineers' Field Research Facility,
located on the U.S. Atlantic coast. Between 50% and 90% of the bathymetric variability at
this site was explained by alongshore-uniform response over the...
This report represents the progress in "Ecological and Radioecological
Studies in the Columbia River Estuary and Adjacent Pacific

Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire...
