2009, Scientific Investigations Report 2009-5078
In response to concerns that excessive plant growth in the lower Yakima River in south-central Washington was degrading water quality and affecting recreational use, the U.S. Geological Survey and the South Yakima Conservation District conducted an assessment of eutrophication in the lower 116 miles of the river during the 2004-07...
Baseline Channel Geometry and Aquatic Habitat Data for Selected Streams in the Matanuska-Susitna Valley, Alaska
Janet H. Curran, William J. Rice
2009, Scientific Investigations Report 2009-5084
Small streams in the rapidly developing Matanuska-Susitna Valley in south-central Alaska are known to support anadromous and resident fish but little is known about their hydrologic and riparian conditions, or their sensitivity to the rapid development of the area or climate variability. To help address this need, channel geometry and...
Vulnerability of carbon storage in North American boreal forests to wildfires during the 21st century
M. S. Balshi, Anthony McGuire, P. Duffy, M. Flannigan, D. W. Kicklighter, J. Melillo
2009, Global Change Biology (15) 1491-1510
The boreal forest contains large reserves of carbon. Across this region, wildfires influence the temporal and spatial dynamics of carbon storage. In this study, we estimate fire emissions and changes in carbon storage for boreal North America over the 21st century. We use a gridded data set developed with...

Amy Pruden, Laurence S. Shore, editor(s)
2009, Book chapter, Hormones and pharmaceuticals generated by concentrated animal feeding operations: transport in water and soil
Although in general, the same drugs are used by humans as for animal husbandry, some compounds are unique to CAFOs. In raising and fattening steers, anabolic steroids are widely used in the US. In the cattle industry, large use is made of the acaricides, avermectins, and the cypermethrins as well...
Pinon and Juniper Field Guide: Asking the Right Questions to Select Appropriate Management Actions

2009, Circular 1335
Pinon-juniper woodlands are an important vegetation type in the Great Basin. Old-growth and open shrub savanna woodlands have been present over much of the last several hundred years. Strong evidence indicates these woodlands have experienced significant tree infilling and major expansion in their distribution since the late 1800s by encroaching...

2009, Transactions of the American Fisheries Society (138) 652-665
Barriers to prevent spawning migrations of sea lampreys Petromyzon marinus remain an important component of an integrated sea lamprey management program in the Laurentian Great Lakes. Concerns about effects on nontarget fishes have led to the construction of specially designed vertical-slot trap-and-sort fishways to mitigate potential barrier effects. To improve passage at...
