Biomonitoring of Environmental Status and Trends (BEST) Program: Environmental contaminants and their effects on fish in the Mississippi River Basin
Christopher J. Schmitt
2002, Biological Science Report 2002-0004
We collected, examined, and analyzed 1378 fish of 22 species from 47 sites in the Mississippi River basin (MRB) during 1995 and from a reference site in 1996. The sampling sites in the MRB represented National Contaminant Biomonitoring Program (NCBP) stations situated at key points on major rivers and National...

Brucellosis in Greater Yellowstone Area (GYA) bison and elk has been a source of controversy and focus of the Greater Yellowstone Interagency Brucellosis Committee (GYIBC) for years. Brucellosis has been eradicated from cattle in the 3 states of Wyoming, Montana, and Idaho and all three states currently are classified as...

2002, Archives of Environmental Contamination and Toxicology (43) 301-308
Concentrations of 14 metals were studied in the soft tissues of zebra mussels (Dreissena polymorpha) and sediments from 16 Great Lakes embayments and riverine environments. Samples were collected in 1993 and 1994 during the early and late autumn period when the body mass of mussels is least affected by reproductive...

Contrasting determinants of abundance in ancestral and colonized ranges of an invasive brood parasite
D.C. Hahn, R.J. O’Connor
J. Michael Scott, Patricia J. Heglund, Michael L. Morrison, Jonathan B. Haufler, William A. Wall, editor(s)
2002, Book chapter, Predicting Species Occurrences : Issues of Accuracy and Scale
Avian species distributions are typically regarded as constrained by spatially extensive variables such as climate, habitat, spatial patchiness, and microhabitat attributes. We hypothesized that the distribution of a brood parasite depends as strongly on host distribution patterns as on biophysical factors and examined this hypothesis with respect to the...

T. Luke George, David S. Dobkin, editor(s)
2002, Book chapter, Effects of habitat fragmentation on birds in western landscapes: contrasts with paradigms from the eastern United States: Studies in Avian Biology No. 25
We evaluated geographical patterns in the abundance and distribution of Brown-headed Cowbirds (Molothrus ater), and in the frequency of cowbird parasitism, across North America in relation to habitat fragmentation. We found no distinctive parasitism patterns at the national or even regional scales, but the species is most abundant in...

Thane H. McCulloh, Robert J. Fleck, Rodger E. Denison, Larry A. Beyer, Richard G. Stanley
2002, Professional Paper 1669
Volcanic rocks, mostly basalts and some andesites, are interbedded with middle Miocene strata and are overlain by younger rocks throughout the greater part of the Los Angeles Basin, California. Roughly correlative flows, previously dated radiometrically (or paleontologically) at about 16.4 to 10.7 Ma, crop out in five separate regions around...

The effects of atmospheric nitrogen deposition in the Rocky Mountains of Colorado and southern Wyoming— A synthesis and critical assessment of published results
Douglas A. Burns
2002, Water-Resources Investigations Report 2002-4066
The Rocky Mountain region of Colorado and southern Wyoming receives as much as 7 kilograms per hectare per year ((kg/ha)/yr) of atmospheric nitrogen (N) deposition, an amount that may have caused changes in aquatic and terrestrial life in otherwise pristine ecosystems. The Rocky Mountain National Park, in its role of...

2002, Open-File Report 2002-460
Introduction Sulfur dioxide (SO2) emission rates from Kilauea Volcano were first measured by Stoiber and Malone (1975) and have been measured on a regular basis since 1979 (Greenland and others, 1985; Casadevall and others, 1987; Elias and others, 1998; Sutton and others, 2001). A compilation of SO2 emission-rate and wind-vector...

Historical trend in ice thickness on the Piscataquis River in central Maine.
Thomas G. Huntington, Robert W. Dudley, Glenn A. Hodgkins
2002, Conference Paper, Proceedings of the 59th Eastern Snow Conference, June 5-7, 2002, Stowe, VT
We analyzed a long-term record of ice thickness on the Piscataquis River in central Maine to determine whether there were temporal trends that were associated with climate warming. Trends in ice thickness were compared and correlated with regional time series of winter air temperature, heating degree days (HDD) , date of river ice-out,...
