Calculation and error analysis of a digital elevation model of Hofsjokull, Iceland, from SAR interferometry Calculation and error analysis of a digital elevation model of Hofsjokull, Iceland, from SAR interferometry
Two ascending European Space Agency (ESA) Earth Resources Satellites (ERS)-1/-2 tandem-mode, synthetic aperture radar (SAR) pairs are used to calculate the surface elevation of Hofsjokull, an ice cap in central Iceland. The motion component of the interferometric phase is calculated using the 30 arc-second resolution USGS GTOPO30 global digital elevation product and one of the ERS tandem...

Metal and sediment ingestion by dabbling ducks Metal and sediment ingestion by dabbling ducks
The chemical analysis of intestinal digesta from hunter-killed carcasses or of wildlife scat is a promising means of estimating the exposure of wildlife to those environmental contaminants that, like lead, are poorly absorbed in the digestive tract. When evaluating contaminants at a site, biologists may find the results of this non-destructive approach more straightforward to interpret...

Hydrogeologic investigations by the U.S. Geological Survey at the former Fort Benjamin Harrison, Marion County, Indiana Hydrogeologic investigations by the U.S. Geological Survey at the former Fort Benjamin Harrison, Marion County, Indiana
As part of the U.S. Department of Defense Base Realignment and Closure process, the former Fort Benjamin Harrison in Marion County, Indiana (called 'Fort Harrison' in this fact sheet), was placed on the Base Closure List in 1991. Property disposal and reuse activities began when Fort Harrison was decommissioned in 1995; work continues through 1999. Fort Harrison was located on...

Fifty-eighth Christmas Bird Count. 166. Ocean City, Md Fifty-eighth Christmas Bird Count. 166. Ocean City, Md
Gauging the impact of manipulative activities, such as rehabilitation or management, on wetlands requires having a notion of the unmanipulated condition as a reference. An understanding of the reference condition requires knowledge of dominant factors influencing ecosystem processes and biological communities. In this paper, we focus on natural physical factors (conditions and processes)...

Relative effects of plumage coloration and vegetation density on nest success Relative effects of plumage coloration and vegetation density on nest success
Many passerine species are highly dichromatic with brightly-colored males and cryptically-colored females. Bright plumage in males is commonly thought to arise as a result of sexual selection by females such that males with bright coloration possess high fitness. However, bright plumage potentially could expose males to increased predation risk. Consistent with this idea, males of many...

Marsh birds and the North American Breeding Bird Survey: judging the value of a landscape level survey for habitat specialist species with low detection rates Marsh birds and the North American Breeding Bird Survey: judging the value of a landscape level survey for habitat specialist species with low detection rates
The North American Breeding Bird Survey was started in 1966, and provides information on population change for >400 species of birds. it covers the continental United States, Canada, and Alaska, and is conducted once each year, in June, by volunteer observers. A 39.4 kIn roadside survey route is driven starting 30 min before sunrise, and a 3 min point count is conducted at each of 50...
