Ore genesis constraints on the Idaho cobalt belt from fluid inclusion gas, noble gas isotope, and ion ratio analyses--a reply
Albert H. Hofstra, Gary P. Landis
2013, Economic Geology (108) 1213-1214
Burlinson (2013) questions the veracity of the H2 concentrations reported for fluid inclusion extracts from minerals in the Idaho cobalt belt (Table 2; Landis and Hofstra, 2012) and suggests that they are an analytical artifact of electron-impact mass spectrometry. He also declares that H2 should not be present in fluid...

Water and sediment temperatures at mussel beds in the upper Mississippi River basin
Teresa J. Newton, Jennifer Sauer, Byron Karns
2013, Freshwater Mollusk Biology and Conservation (16) 53-62
Native freshwater mussels are in global decline and urgently need protection and conservation. Declines in the abundance and diversity of North American mussels have been attributed to human activities that cause pollution, waterquality degradation, and habitat destruction. Recent studies suggest that effects of climate change may also endanger native mussel...

Jason G. Romine, Joseph R. Benjamin, Russell W. Perry, Lynne Casal, Patrick J. Connolly, Sally S. Sauter
2013, Open-File Report 2013-1154
Marine subsidies can play an important role in the growth, survival, and migratory behavior of rearing juvenile salmonids. Availability of high-energy, marine-derived food sources during critical decision windows may influence the timing of emigration or the decision to forego emigration completely and remain in the freshwater environment. Increasing growth and...

Optimization of water-level monitoring networks in the eastern Snake River Plain aquifer using a kriging-based genetic algorithm method
Jason C. Fisher
2013, Scientific Investigations Report 2013-5120
Long-term groundwater monitoring networks can provide essential information for the planning and management of water resources. Budget constraints in water resource management agencies often mean a reduction in the number of observation wells included in a monitoring network. A network design tool, distributed as an R package, was developed to...

2013, Open-File Report 2013-1148
Mercury (Hg) is a globally distributed pollutant that poses considerable risks to human and wildlife health. Over the past 150 years since the advent of the industrial revolution, approximately 80 percent of global emissions have come from anthropogenic sources, largely fossil fuel combustion. As a result, atmospheric deposition of Hg...

Mark E. Savoca, Gabriel B. Senay, Molly A. Maupin, Joan F. Kenny, Charles A. Perry
2013, Scientific Investigations Report 2013-5126
Remote-sensing technology and surface-energy-balance methods can provide accurate and repeatable estimates of actual evapotranspiration (ETa) when used in combination with local weather datasets over irrigated lands. Estimates of ETa may be used to provide a consistent, accurate, and efficient approach for estimating regional water withdrawals for irrigation and associated consumptive...
Relationships between nutrient enrichment, pleurocerid snail density and trematode infection rate in streams
Serena Ciparis, Deborah D. Iwanowicz, J. Reese Voshell Jr.
2013, Freshwater Biology (58) 1392-1404
Summary 1. Nutrient enrichment is a widespread environmental problem in freshwater ecosystems. Eutrophic conditions caused by nutrient enrichment may result in a higher prevalence of infection by trematode parasites in host populations, due to greater resource availability for the molluscan first intermediate hosts. 2. This study examined relationships among land use, environmental...

Michelle H. Reynolds, Emily Weiser, Ian Jamieson, Jeffrey S. Hatfield
2013, Journal of Wildlife Management (77) 1094-1103
Population variation in life history can be important for predicting successful establishment and persistence of reintroduced populations of endangered species. The Laysan duck (Anas laysanensis) is an endangered bird native to the Hawaiian Archipelago that was extirpated from most islands after the introduction of mammalian predators. Laysan ducks were restricted...
Modeling the colonization of Hawaii by hoary bats (Lasiurus cinereus)
Frank J. Bonaccorso, Liam P. McGuire
2013, Book chapter, Bat Evolution, Ecology, and Conservation
The Hawaiian archipelago, the most isolated cluster of islands on Earth, has been colonized successfully twice by bats. The putative “lava tube bat” of Hawaii is extinct, whereas the Hawaiian Hoary Bat, Lasiurus cinereus semotus, survives as an endangered species. We conducted a three-stage analysis to identify conditions under which...
