Thierry M. Work, Greta S. Aeby
2011, Journal of Invertebrate Pathology (107) 127-131
We performed histological examination of 69 samples of Acropora sp. manifesting different types of tissue loss (Acropora White Syndrome-AWS) from Hawaii, Johnston Atoll and American Samoa between 2002 and 2006. Gross lesions of tissue loss were observed and classified as diffuse acute, diffuse subacute, and focal to multifocal acute to...

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...

Flood-frequency analyses from paleoflood investigations for Spring, Rapid, Boxelder, and Elk Creeks, Black Hills, western South Dakota
Tessa M. Harden, Jim E. O'Connor, Daniel G. Driscoll, John F. Stamm
2011, Scientific Investigations Report 2011-5131
Flood-frequency analyses for the Black Hills area are important because of severe flooding of June 9-10, 1972, that was caused by a large mesoscale convective system and caused at least 238 deaths. Many 1972 peak flows are high outliers (by factors of 10 or more) in observed records that date...

Deposit model for volcanogenic uranium deposits
George N. Breit, Susan M. Hall
2011, Open-File Report 2011-1255
Volcanism is a major contributor to the formation of important uranium deposits both close to centers of eruption and more distal as a result of deposition of ash with leachable uranium. Hydrothermal fluids that are driven by magmatic heat proximal to some volcanic centers directly form some deposits. These fluids...
Earthquakes in Hawai‘i—an underappreciated but serious hazard
Paul G. Okubo, Jennifer S. Nakata
2011, Fact Sheet 2011-3013
The State of Hawaii has a history of damaging earthquakes. Earthquakes in the State are primarily the result of active volcanism and related geologic processes. It is not a question of "if" a devastating quake will strike Hawai‘i but rather "when." Tsunamis generated by both distant and local quakes are...

Seth M. Munson, Jayne Belnap, Charles D. Schelz, Mary Moran, Tara W. Carolin
2011, Ecosphere (2)
The intensification of aridity due to anthropogenic climate change in the southwestern U.S. is likely to have a large impact on the growth and survival of plant species that may already be vulnerable to water stress. To make accurate predictions of plant responses to climate change, it is essential to...
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...
Optimal timing for managed relocation of species faced with climate change
Eve McDonald Madden, Michael C. Runge, Hugh P. Possingham, Tara G. Martin
2011, Nature Climate Change (1) 261-265
Managed relocation is a controversial climate-adaptation strategy to combat negative climate change impacts on biodiversity. While the scientific community debates the merits of managed relocation1,2,3,4,5,6,7,8,9,10,11,12, species are already being moved to new areas predicted to be more suitable under climate change13,14. To inform these moves, we construct a quantitative decision...
