Michael C. Hayes, Reginald R. Reisenbichler, Stephen P. Rubin, Lisa A. Wetzel, Anne R. Marshall
2011, Transactions of the American Fisheries Society (140) 1305-1316
Differential survival and growth were tested in Chinook salmon Oncorhynchus tshawytscha expressing two common alleles, *–100 and *–260, at the superoxide dismutase locus (sSOD-1*). These tests were necessary to support separate studies in which the two alleles were used as genetic marks under the assumption of mark neutrality. Heterozygous adults...

Occupancy and abundance of wintering birds in a dynamic agricultural landscape
Mark W. Miller, Elise V. Pearlstine, Robert M. Dorazio, Frank J. Mazzotti
2011, Journal of Wildlife Management (75) 836-847
Assessing wildlife management action requires monitoring populations, and abundance often is the parameter monitored. Recent methodological advances have enabled estimation of mean abundance within a habitat using presence–absence or count data obtained via repeated visits to a sample of sites. These methods assume populations are closed and intuitively assume habitats...

Observations of debris flows at Chalk Cliffs, Colorado, USA: Part 1, in-situ measurements of flow dynamics, tracer particle movement and video imagery from the summer of 2009
Scott W. McCoy, Jeffrey A. Coe, Jason W. Kean, Greg E. Tucker, Dennis M. Staley, Thad A. Wasklewicz
2011, Italian Journal of Engineering Geology and Environment 715-726
Debris flows initiated by surface-water runoff during short duration, moderate- to high-intensity rainfall are common in steep, rocky, and sparsely vegetated terrain. Yet large uncertainties remain about the potential for a flow to grow through entrainment of loose debris, which make formulation of accurate mechanical models of debris-flow routing difficult....

2011, Open-File Report 2011-1170
Selected aspects of National Atmospheric Deposition Program / National Trends Network (NADP/NTN) protocols are evaluated in four studies. Meteorological conditions have minor impacts on the error in NADP/NTN sampling. Efficiency of frozen precipitation sample collection is lower than for liquid precipitation samples. Variability of NTN measurements is higher for relatively...
