D.M. Nelson, S.H. Feng, E.C. Grimm, B. Brandon Curry, J.E. Slate
2006, Ecology (87) 2523-2536
The role of climate and fire in the development, maintenance, and species composition of prairie in the eastern axis of the tallgrass Prairie Peninsula intrigued early North American ecologists. However, evaluation of the long-standing hypotheses about the region's environmental history has been hampered by the scarcity of paleorecords. We conducted...

Sandra L. Talbot, Judy R. Gust, George K. Sage, Anthony S. Fischbach, Kristin S. Amstrup, William Leacock, Larry Van Daele
2006, Report
Here we examine genetic characteristics of brown bears of Kodiak and Afognak islands, using 14 variable nuclear microsatellite loci and nucleotide sequence information including the hypervariable domain I of the mtDNA control region (Wakely 1993). Because these markers, or a subset of them, have been used to characterize brown bears...

Methods Used to Assess the Susceptibility to Contamination of Transient, Non-Community Public Ground-Water Supplies in Indiana
Leslie D. Arihood, David A. Cohen
2006, Scientific Investigations Report 2005-5059
The Safe Water Drinking Act of 1974 as amended in 1996 gave each State the responsibility of developing a Source-Water Assessment Plan (SWAP) that is designed to protect public-water supplies from contamination. Each SWAP must include three elements: (1) a delineation of the source-water protection area, (2) an inventory of...
Evidence for intensification of the global water cycle: Review and synthesis
Thomas G. Huntington
2006, Journal of Hydrology (319) 83-95
One of the more important questions in hydrology is: if the climate warms in the future, will there be an intensification of the water cycle and, if so, the nature of that intensification? There is considerable interest in this question because an intensification of the water cycle may lead to changes in water-resource availability,...
