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...

The U.S. Geological Survey (USGS) collaborated with European geologists to assess resources in porphyry copper deposits in Europe, exclusive of Scandinavia (Sweden, Denmark, Norway, and Finland) and Russia. Porphyry copper deposits in Europe are Paleozoic and Late Cretaceous to Miocene in age. A number of the 31 known Phanerozoic deposits...
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...

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...

Scott A. Minor, Mark R. Hudson, Jonathan S. Caine, Ren A. Thompson
2013, GSA Special Papers (494) 345-382
The structural geometry of transfer and accommodation zones that relay strain between extensional domains in rifted crust has been addressed in many studies over the past 30 years. However, details of the kinematics of deformation and related stress changes within these zones have received relatively little attention. In this study...

Laura S. Robertson, Gary M. Fellers, Jamie Marie Marranca, Patrick M. Kleeman
2013, Diseases of Aquatic Organisms (104) 225-236
Frogs secrete antimicrobial peptides onto their skin. We describe an assay to preserve and analyze antimicrobial peptide transcripts from field-collected skin secretions that will complement existing methods for peptide analysis. We collected skin secretions from 4 North American species in the field in California and 2 species in the laboratory....

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...

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...

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...

2013, Book chapter, Conservation biology: voices from the tropics
This chapter identifies four key challenges and opportunities for long-term conservation of biodiversity in the Hawaii's Islands. Following are the challenges that need to be resolved for remaining species of native forest birds to survive into the next century: invasive species, landscape processes, social factors, and climate change. These challenges...
Effects of sampling conditions on DNA-based estimates of American black bear abundance
Jared S. Laufenberg, Frank T. van Manen, Joseph D. Clark
2013, Journal of Wildlife Management (77) 1010-1020
DNA-based capture-mark-recapture techniques are commonly used to estimate American black bear (Ursus americanus) population abundance (N). Although the technique is well established, many questions remain regarding study design. In particular, relationships among N, capture probability of heterogeneity mixtures A and B (pA and pB, respectively, or p, collectively), the proportion...

Joshua R. Ennen, A. Floyd Scott
2013, Chelonian Conservation and Biology (12) 199-203
Little is known about the movement behavior of the stripe-necked musk turtle, Sternotherus minor peltifer. Using radiotelemetry, we calculated mean (± SD) home range length, which was 341.4 ± 90.3 m, with home range length not differing between the sexes (males, 335 ± 194 m; females, 346 ± 79.5 m). Sternotherus m. peltifer were active in every...
