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...

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...

Does winter region affect spring arrival time and body mass of king eiders in northern Alaska?
Abby N. Powell, Steffen Oppel
2009, Polar Biology (32) 1203-1209
Events during the non-breeding season may affect the body condition of migratory birds and influence performance during the following breeding season. Migratory birds nesting in the Arctic often rely on endogenous nutrients for reproductive efforts, and are thus potentially subject to such carry-over effects. We tested whether king eider (<i...
