Arsenic is derived from historical deposition of smelter emissions (Mill and Willow Creeks) and historical mining and milling wastes (Silver Bow Creek). Although long-term monitoring has characterized the general seasonal and flow-related trends in As concentrations in these streams and the pond system used to treat Silver Bow Creek water, little is known about solubility controls and sorption processes that influence diel cycles in As concentrations.</p><p>Diel (24-h) sampling was conducted in July 2004 and August 2005 at the outlet of the treatment ponds, at two locations along a nearby reconstructed stream channel that diverts tributary water around the ponds, and at Silver Bow Creek 2&nbsp;km below the ponds. Dissolved As concentration increased up to 51% during the day at most of the stream sites, whereas little or no diel change was displayed at the treatment-pond outlet. The strong cycle in streams is explained by pH- and temperature-dependent sorption of As onto hydrous metal oxides or biofilms on the streambed. Concentrations of dissolved Ca<sup>2+</sup><span>&nbsp;</span>and HCO<sub>3</sub><sup>−</sup><span>&nbsp;</span>at the stream sites showed a diel temporal pattern opposite to that of As, and geochemical modeling supports the hypothesis that the concentrations of Ca<sup>2+</sup><span>&nbsp;</span>and HCO<sub>3</sub><sup>−</sup><span>&nbsp;</span>were controlled by precipitation of calcite during the warm afternoon hours when pH rose above 9.0. Nightly increases in dissolved Mn and Fe(II) concentrations were out of phase with concentrations of other divalent cations and are more likely explained by redox phenomena.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science of the Total Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.scitotenv.2007.06.029","issn":"00489697","usgsCitation":"Gammons, C., Grant, T., Nimick, D.A., Parker, S., and DeGrandpre, M., 2007, Diel changes in water chemistry in an arsenic-rich stream and treatment-pond system: Science of the Total Environment, v. 384, no. 1-3, p. 433-451, https://doi.org/10.1016/j.scitotenv.2007.06.029.","productDescription":"19 p.","startPage":"433","endPage":"451","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":239726,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212264,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2007.06.029"}],"country":"United States","state":"Montana","otherGeospatial":"Warm Springs Ponds Operable Unit, Clark Fork River Superfund site","volume":"384","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00bfe4b0c8380cd4f8c6","contributors":{"authors":[{"text":"Gammons, C.H.","contributorId":18459,"corporation":false,"usgs":true,"family":"Gammons","given":"C.H.","affiliations":[],"preferred":false,"id":431664,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grant, T.M.","contributorId":87756,"corporation":false,"usgs":true,"family":"Grant","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":431667,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nimick, David A. dnimick@usgs.gov","contributorId":421,"corporation":false,"usgs":true,"family":"Nimick","given":"David","email":"dnimick@usgs.gov","middleInitial":"A.","affiliations":[{"id":573,"text":"Special Applications Science Center","active":true,"usgs":true},{"id":5050,"text":"WY-MT Water Science Center","active":true,"usgs":true}],"preferred":true,"id":431666,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Parker, S.R.","contributorId":62725,"corporation":false,"usgs":true,"family":"Parker","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":431665,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"DeGrandpre, M.D.","contributorId":9461,"corporation":false,"usgs":true,"family":"DeGrandpre","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":431663,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In two feeding tests, two-month-old fatmucket (Lampsilis siliquoidea) and rainbow mussel (Villosa iris) were fed various live algae or nonviable algal mixture for 28 d. The algal mixture was the best food resulting in high survival (???90%) and growth. Multiple copper and ammonia toxicity tests were conducted for 28 d starting with two-month-old mussels. Six toxicity tests using the algal mixture were successfully completed with a control survival of 88 to 100%. Among copper tests with rainbow mussel, fatmucket, and oyster mussel (Epioblasma capsaeformis), chronic value ([ChV], geometric mean of the no-observed-effect concentration and the lowest-observed-effect concentration) ranged from 8.5 to 9.8 ??g Cu/L for survival and from 4.6 to 8.5 ??g Cu/L for growth. Among ammonia tests with rainbow mussel, fatmucket, and wavy-rayed lampmussel (L. fasciola), the ChV ranged from 0.37 to 1.2 mg total ammonia N/L for survival and from 0.37 to 0.67 mg N/L for growth. These ChVs were below the U.S. Environmental Protection Agency 1996 chronic water quality criterion (WQC) for copper (15 ??g/L; hardness 170 mg/L) and 1999 WQC for total ammonia (1.26 mg N/L; pH 8.2 and 20??C). Results indicate that toxicity tests with two-month-old mussels can be conducted for 28 d with &gt;80% control survival; growth was frequently a more sensitive endpoint compared to survival; and the 1996 chronic WQC for copper and the 1999 chronic WQC for total ammonia might not be adequately protective of the mussel species tested. However, a recently revised 2007 chronic WQC for copper based on the biotic ligand model may be more protective in the water tested. ?? 2007 SETAC.</p>","language":"English","publisher":"Wiley","doi":"10.1897/06-524R.1","issn":"07307268","usgsCitation":"Wang, N., Ingersoll, C., Greer, I., Hardesty, D., Ivey, C., Kunz, J., Brumbaugh, W.G., Dwyer, F., Roberts, A., Augspurger, T., Kane, C., Neves, R.J., and Barnhart, M., 2007, Chronic toxicity of copper and ammonia to juvenile freshwater mussels (Unionidae): Environmental Toxicology and Chemistry, v. 26, no. 10, p. 2048-2056, https://doi.org/10.1897/06-524R.1.","productDescription":"9 p.","startPage":"2048","endPage":"2056","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":239758,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212294,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/06-524R.1"}],"volume":"26","issue":"10","noUsgsAuthors":false,"publicationDate":"2007-10-01","publicationStatus":"PW","scienceBaseUri":"5059f5eee4b0c8380cd4c4c0","contributors":{"authors":[{"text":"Wang, N.","contributorId":81615,"corporation":false,"usgs":true,"family":"Wang","given":"N.","email":"","affiliations":[],"preferred":false,"id":431679,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ingersoll, C.G. 0000-0003-4531-5949","orcid":"https://orcid.org/0000-0003-4531-5949","contributorId":56338,"corporation":false,"usgs":true,"family":"Ingersoll","given":"C.G.","affiliations":[],"preferred":false,"id":431677,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Greer, I.E.","contributorId":70182,"corporation":false,"usgs":true,"family":"Greer","given":"I.E.","email":"","affiliations":[],"preferred":false,"id":431678,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hardesty, D.K.","contributorId":43935,"corporation":false,"usgs":true,"family":"Hardesty","given":"D.K.","email":"","affiliations":[],"preferred":false,"id":431676,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ivey, C.D.","contributorId":33876,"corporation":false,"usgs":true,"family":"Ivey","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":431675,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kunz, J.L.","contributorId":7872,"corporation":false,"usgs":true,"family":"Kunz","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":431672,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Brumbaugh, W.

Quantitatively characterizing TIR (5-25 ??m) spectral changes that accompany structural changes between glasses and mineral crystals provides the means to understand natural glasses on Earth and Mars. A suite of glasses with compositions analogous to common terrestrial volcanic glasses was created and analyzed using TIR reflectance and emission techniques. Documented spectral characteristics provide a basis for comparison with TIR spectra of other amorphous materials (glasses, clays, etc.).

Sensitivity analyses suggest that in the Outer Banks, the rate of sea-level rise is the most important factor in determining how barrier islands evolve. The Holocene simulation provides a basis for future simulations, which suggest that if sea level rises up to 0.88 m by AD 2100, as predicted by the highest estimates of the Intergovernmental Panel on Climate Change, the barrier in the study area may migrate on the order of 2.5 times more rapidly than at present. If sea level rises beyond IPCC predictions to reach 1.4–1.9 m above modern sea level by AD 2100, model results suggest that barrier islands in the Outer Banks may become vulnerable to threshold collapse, disintegrating during storm events, by the end of the next century. Consistent with sensitivity analyses, additional simulations indicate that anthropogenic activities, such as increasing the rate of sediment supply through beach nourishment, will only slightly affect barrier island migration rates and barrier island vulnerability to collapse.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceLocation":"New Orleans, LA","language":"English","publisher":"American Society of Civil Engineers","doi":"10.1061/40926(239)89","isbn":"0784409269; 9780784409268","usgsCitation":"Moore, L.J., List, J., Williams, S.J., and Stolper, D., 2007, Modeling barrier island response to sea-level rise in the Outer Banks, North Carolina, <i>in</i> Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, New Orleans, LA, p. 1153-1164, https://doi.org/10.1061/40926(239)89.","productDescription":"12 p.","startPage":"1153","endPage":"1164","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":239759,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212295,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/40926(239)89"}],"country":"United States","state":"North Carolina","otherGeospatial":"Outer Banks","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75.531626,35.292798 ], [ -75.531626,35.77543 ], [ -75.459951,35.77543 ], [ -75.459951,35.292798 ], [ -75.531626,35.292798 ] ] ] } } ] }","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505a5be1e4b0c8380cd6f888","contributors":{"authors":[{"text":"Moore, Laura J.","contributorId":39452,"corporation":false,"usgs":true,"family":"Moore","given":"Laura","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":431687,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"List, Jeffrey H. jlist@usgs.gov","contributorId":2416,"corporation":false,"usgs":true,"family":"List","given":"Jeffrey H.","email":"jlist@usgs.gov","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":false,"id":431686,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Williams, S.

Mussel species potentially compete for food and space as adults, and for fish host resources during the larval (glochidial) stage. Resource partitioning at the larval stage may promote coexistence. A model of resource utilization was developed for two mussel species and analyzed to determine conditions for coexistence. Mussel species were predicted to coexist when they differed in terms of their success in contacting different fish host species; very similar strategies offered limited possibilities for coexistence. Differences in the mussel species' maximum infestation loads on the fish hosts that coincided with differences in their fish host contact success promoted coexistence. Mussel species with a given set of trade-offs in fish host use were predicted to coexist only for a subset of relative fish host abundances, so a shift in relative fish host abundances could result in the loss of a mussel species. An understanding of the conditions for freshwater mussel species coexistence can help explain high mussel diversity in rivers and guide ongoing conservation activities. ?? 2006 Elsevier B.V.

The hillslope ground water originated as recharge from intermittently grazed pasture up slope of the site. In the hillslope transect perpendicular to the stream, ground water NO3− concentrations decreased from ∼3 mg N L−1 beneath the ridge (80 m from the channel) to 0.01 to 1.0 mg N L−1 at wells 1 to 3 m from the channel. The Cl− concentrations and NO3/Cl ratios decreased toward the channel indicating NO3− dilution and biotic retention. In the bankside well transect parallel to the stream, two distinct ground water environments were observed: an alluvial environment upstream of a relict beaver dam influenced by stream water and a hillslope environment downstream of the relict beaver dam. Nitrate was elevated to levels representative of agricultural runoff in a third well transect located ∼5 m from the stream to assess the effectiveness of the riparian zone as a NO3− sink. Subsurface NO3− injections revealed transport of up to 15 mg N L−1 was nearly conservative in the alluvial riparian environment. Addition of glucose stimulated dissolved oxygen uptake and promoted NO3− retention under both background and elevated NO3− levels in summer and winter. Disappearance of added NO3− was followed by transient NO2− formation and, in the presence of C2H2, by N2O formation, demonstrating potential denitrification. Under current land use, most NO3− associated with local ground water is biotically retained or diluted before reaching the channel. However, elevating NO3− levels through agricultural cultivation would likely result in increased NO3− transport to the channel.</p>","language":"English","publisher":"Wiley","doi":"10.2134/jeq2006.0019","issn":"00472425","usgsCitation":"Duff, J., Jackman, A.P., Triska, F., Sheibley, R., and Avanzino, R., 2007, Nitrate retention in riparian ground water at natural and elevated nitrate levels in North Central Minnesota: Journal of Environmental Quality, v. 36, no. 2, p. 343-353, https://doi.org/10.2134/jeq2006.0019.","productDescription":"11 p.","startPage":"343","endPage":"353","numberOfPages":"11","costCenters":[],"links":[{"id":242654,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Minnesota","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -95.04098355965877,\n              47.16920731114888\n            ],\n            [\n              -95.04098355965877,\n              46.842187352721595\n            ],\n            [\n              -94.43040152655558,\n              46.842187352721595\n            ],\n            [\n              -94.43040152655558,\n              47.16920731114888\n            ],\n            [\n              -95.04098355965877,\n              47.16920731114888\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"36","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a66afe4b0c8380cd72f11","contributors":{"authors":[{"text":"Duff, J.H.","contributorId":60377,"corporation":false,"usgs":true,"family":"Duff","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":433635,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jackman, A.

Ridge characteristics produced by these storms include: heights of 1–4 m, widths of 8–50 m, and lengths up to 18 km. The ridges tend to be higher and steeper on their landward margins than on their seaward margins and are composed mostly of re-worked coral rubble derived from reef front settings with smaller amounts of fresh broken coral (5–30%). Characteristics of these modern gravel storm ridges can be used to help identify ancient storm deposits and to differentiate between other coarse-grained deposits such as those created by tsunamis.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceLocation":"New Orleans, LA","language":"English","publisher":"American Society of Civil Engineers","doi":"10.1061/40926(239)43","isbn":"0784409269; 9780784409268","usgsCitation":"Richmond, B.M., and Morton, R., 2007, Coral-gravel storm ridges: examples from the tropical Pacific and Caribbean, <i>in</i> Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, New Orleans, LA, p. 572-583, https://doi.org/10.1061/40926(239)43.","productDescription":"12 p.","startPage":"572","endPage":"583","numberOfPages":"12","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":212324,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/40926(239)43"},{"id":239791,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"5059fc0ce4b0c8380cd4e0cf","contributors":{"authors":[{"text":"Richmond, Bruce M. 0000-0002-0056-5832 brichmond@usgs.gov","orcid":"https://orcid.org/0000-0002-0056-5832","contributorId":2459,"corporation":false,"usgs":true,"family":"Richmond","given":"Bruce","email":"brichmond@usgs.gov","middleInitial":"M.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":431689,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morton, Robert A.","contributorId":88333,"corporation":false,"usgs":true,"family":"Morton","given":"Robert A.","affiliations":[],"preferred":false,"id":431690,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Fire and herbivory effects on the nutritive quality of savanna vegetation can occur directly, independent of changes in the plant community, or indirectly, via effects on the plant community. Indirect effects can be further subdivided into those occurring because of changes in plant species composition or plant abundance (i.e., quality versus quantity). We studied relationships between fire, herbivory, rainfall, soil fertility, and leaf nitrogen (N), phosphorus (P), and sodium (Na) at 30 sites inside and outside of Serengeti National Park. Using structural equation modeling, we asked whether fire and herbivory influences were largely direct or indirect and how their signs and strengths differed within the context of natural savanna processes. Herbivory was associated with enhanced leaf N and P through changes in plant biomass and community composition. Fire was associated with reduced leaf nutrient concentrations through changes in plant community composition. Additionally, fire had direct positive effects on Na and nonlinear direct effects on P that partially mitigated the indirect negative effects. Key mechanisms by which fire reduced plant nutritive quality were through reductions of Na-rich grasses and increased abundance of Themeda triandra, which had below-average leaf nutrients. ?? 2007 by The University of Chicago.

Egg contents were analyzed for a broad spectrum of organochlorine (OC) contaminants, mercury (Hg), and stable isotopes of carbon (??13C) and nitrogen (??15N). Concentrations of polychlorinated biphenyls (??PCBs), p,p???- dichlorodiphenyldichloroethylene (DDE), and Hg in bald eagle eggs were elevated throughout the archipelago, but the patterns of distribution differed among the various contaminants. Total PCBs were highest in areas of past military activities on Adak and Amchitka Islands, indicating local point sources of these compounds. Concentrations of DDE and Hg were higher on Amchitka Island, which was subjected to much military activity during World War II and the middle of the 20th century. Concentrations of ??PCBs also were elevated on islands with little history of military activity (e.g., Amlia, Tanaga, Buldir), suggesting non-point sources of PCBs in addition to point sources. Concentrations of DDE and Hg were highest in eagle eggs from the most western Aleutian Islands (e.g., Buldir, Kiska) and decreased eastward along the Aleutian chain. This east-to-west increase suggested a Eurasian source of contamination, possibly through global transport and atmospheric distillation and/or from migratory seabirds. Eggshell thickness and productivity of bald eagles were normal and indicative of healthy populations because concentrations of most contaminants were below threshold levels for effects on reproduction. Contrary to our predictions, contaminant concentrations were not correlated with stable isotopes of carbon (??13C) or nitrogen (??15N) in eggs.

Such use requires critical evaluation when harvest regulations force hunters to selectively harvest specific age classes, due to impact on the underlying population age structure. We used a stochastic population simulation model to evaluate the impact of using harvest proportions to evaluate changes in population age structure under a selective harvest management program at two scales. Using harvest proportions to parameterize the age-specific harvest segment of the model for the local scale showed that predictions of post-harvest age structure did not vary dependent upon whether selective harvest criteria were in use or not. At the county scale, yearling frequency in the post-harvest population increased, but model predictions indicated that post-harvest population size of 2.5 years old males would decline below levels found before implementation of the antler restriction, reducing the number of individuals recruited into older age classes. Across the range of age-specific harvest rates modeled, our simulation predicted that underestimation of age-specific harvest rates has considerable influence on predictions of post-harvest population age structure. We found that the consequence of uncertainty in harvest rates corresponds to uncertainty in predictions of residual population structure, and this correspondence is proportional to scale. Our simulations also indicate that regardless of use of harvest proportions or harvest rates, at either the local or county scale the modeled SHC had a high probability (>0.60 and >0.75, respectively) of eliminating recruitment into >2.5 years old age classes. Although frequently used to increase population age structure, our modeling indicated that selective harvest criteria can decrease or eliminate the number of white-tailed deer recruited into older age classes. Thus, we suggest that using harvest proportions for management planning and evaluation should be viewed with caution. In addition, we recommend that managers focus more attention on estimation of age-specific harvest rates, and modeling approaches which combine harvest rates with information from harvested individuals to further increase their ability to effectively manage deer populations under selective harvest programs. ?? 2006 Elsevier B.V.

Adaptive strategies include resistance options (forestall impacts and protect highly valued resources), resilience options (improve the capacity of ecosystems to return to desired conditions after disturbance), and response options (facilitate transition of ecosystems from current to new conditions). Mitigation strategies include options to sequester carbon and reduce overall greenhouse gas emissions.

Consequently, chronic exposure to elevated noise levels in tanks could negatively impact cultured species. Possible effects include impairment of the auditory system, increased stress, and reduced growth rates. The objective of this study was to evaluate the long-term effects of sound exposure on the hearing sensitivity, growth, and survival of cultured rainbow trout (Oncorhynchus mykiss). Two cohorts of rainbow trout were cultured for 8??months in replicated tanks consisting of three sound treatments: 115, 130, or 150 decibels referenced at 1 micropascal (dB re 1????Pa root mean square [RMS]) levels. Auditory evoked potential (AEP) recordings revealed no significant differences in hearing thresholds resulting from exposure to increased ambient sound levels. Although there was no evident noise-induced hearing loss, there were significant differences in hearing thresholds between the two fish cohorts examined. No statistical effect of sound treatment was found for growth rate and mortality within each fish cohort. There was no significant difference in mortality between sound treatments when fish were exposed to the pathogen Yersinia ruckeri, but there was significantly different mortality between cohorts. This study indicated that rainbow trout hearing sensitivity, growth, survival, stress, and disease susceptibility were not negatively impacted by noise levels common to recirculating aquaculture systems. These findings should not be generalized to all cultured fish species, however, because many species, including catfish and cyprinids, have much greater hearing sensitivity than rainbow trout and could be affected differently by noise. ?? 2007 Elsevier B.V.

The hemagglutinin (HA) and neuraminidase (NA) genes from all 6 H5N1 viruses and an additional 38 North American wild-bird-origin H5 subtype and 28 N1 subtype viruses were sequenced and compared with sequences available in GenBank by phylogenetic analysis. Both HA and NA were phylogenetically distinct from those for viruses from outside of North America and from those for viruses recovered from mammals. Four of the H5N1 AI viruses were characterized as low pathogenicity by standard in vivo pathotyping tests. One of the H5N1 viruses, A/MuteSwan/MI/451072-2/06, was shown to replicate to low titers in chickens, turkeys, and ducks. However, transmission of A/MuteSwan/MI/451072-2/06 was more efficient among ducks than among chickens or turkeys based on virus shed. The 50% chicken infectious dose for A/MuteSwan/MI/451072-2/06 and three other wild-waterfowl-origin H5 viruses were also determined and were between 10 5.3 and 107.5 50% egg infective doses. Finally, seven H5 viruses representing different phylogenetic clades were evaluated for their antigenic relatedness by hemagglutination inhibition assay, showing that the antigenic relatedness was largely associated with geographic origin. Overall, the data support the conclusion that North American H5 wild-bird-origin AI viruses are low-pathogenicity wild-bird-adapted viruses and are antigenically and genetically distinct from the highly pathogenic Asian H5N1 virus lineage.

In recent years, the probability of detecting defined population trends has been the most common method of assessing monitoring programs. Such analyses require many assumptions, including a model for population change and a model for variance. To demonstrate potential effects of these assumptions on power analysis results, we present data for Red-tailed Tropicbirds (Phaethon rubricauda) from Tern Island, Hawaii. Depending on our assumptions, the power to detect a 50% decline over 10 years varied from 80% to 100%. We argue that monitoring standards based upon the ability to detect population trends should be applied cautiously. As a complementary approach, we propose that monitoring standards should emphasize attributes of sampling design that increase precision (e.g., randomization, bias, and detection probability). By using standards of precision, managers can focus on the sources of variation that can be minimized. A sampling design approach to monitoring standards provides a useful complement to standards of statistical power to detect annual trends.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2007.08.007","issn":"00063207","usgsCitation":"Seavy, N., and Reynolds, M., 2007, Is statistical power to detect trends a good assessment of population monitoring?: Biological Conservation, v. 140, no. 1-2, p. 187-191, https://doi.org/10.1016/j.biocon.2007.08.007.","startPage":"187","endPage":"191","numberOfPages":"5","costCenters":[],"links":[{"id":212472,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2007.08.007"},{"id":239962,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"140","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3f2ce4b0c8380cd64306","contributors":{"authors":[{"text":"Seavy, N.E.","contributorId":26403,"corporation":false,"usgs":true,"family":"Seavy","given":"N.E.","affiliations":[],"preferred":false,"id":431747,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, M.H. 0000-0001-7253-8158","orcid":"https://orcid.org/0000-0001-7253-8158","contributorId":64214,"corporation":false,"usgs":true,"family":"Reynolds","given":"M.H.","affiliations":[],"preferred":false,"id":431748,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The ages of dune emplacement range from 0.1 to 103??ka based on radiocarbon (36 samples) and luminescence (46 samples) dating techniques. The majority of the emplacement dates fall into two periods of late-Pleistocene age (11-103??ka) and mid-late-Holocene age (0.1-8??ka) that correspond to marine low-stand and marine high-stand conditions, respectively. The distribution of both the late-Pleistocene dune sheets (516??km2 total surface area) and the late-Holocene dune sheets (184??km2) are concentrated (90% of total surface area) along a 100??km coastal reach of the south-central Oregon coast. This coastal reach lies directly landward of a major bight (Heceta-Perpetua-Stonewall Banks) on the continental shelf, at depths of 30-200??m below present mean sea level (MSL). The banks served to trap northward littoral drift during most of the late-Pleistocene conditions of lowered sea level (- 50 ?? 20??m MSL). The emerged inner-shelf permitted cross-shelf, eolian sand transport (10-50??km distance) by onshore winds. The depocenter sand deposits were reworked by the Holocene marine transgression and carried landward by asymmetric wave transport during early- to mid-Holocene time. The earliest dated onset of Holocene dune accretion occurred at 8??ka in the central Oregon coast. A northward migration of Northeast Pacific storm tracks to the latitude of the shelf depocenter (Stonewall, Perpetua, Heceta Banks) in Holocene time resulted in eastward wave transport from the offshore depocenter. The complex interplay of coastal morphology, paleosea-level, and paleoclimate yielded the observed peak distribution of beach and dune sand observed along the south-central Oregon coast. ?? 2007 Elsevier B.V.

This suggests that thiadiamondoids and diamondoidthiols form during TSR. In order to prove this hypothesis, we perform laboratory TSR experiments on diverse organic compounds using sodium sulfate as an oxidant in the presence of elemental sulfur and deionized water at 200 and 350 °C for 48 and 96 h under acidic conditions (pH = 4). Our results show that thiadiamondoids and diamondoidthiols can be created from non-sulfur-containing diamondoids by TSR. It seems likely that diamondoid species are organic precursors of thiadiamondoids and diamondoidthiols. In addition, thiocholesterol yields trace quantities of dimethyl-2-thiaadamantanes when heated with montmorillonite at 200 °C, suggesting that these diamondoid derivatives may partly originate by molecular rearrangement of polycyclic sulfides and thiols in the presence of acidic clay minerals since they also exist in crude oil that has not undergone TSR. The present study of these heteroatomic cage compounds improves understanding of TSR and can be used to reduce risk in petroleum exploration.</p></div></div></div></div></div>","language":"English","publisher":"American Chemical Society","doi":"10.1021/ef7003333","issn":"08870624","usgsCitation":"Wei, Z., Moldowan, J., Fago, F., Dahl, J., Cai, C., and Peters, K.E., 2007, Origins of thiadiamondoids and diamondoidthiols in petroleum: Energy and Fuels, v. 21, no. 6, p. 3431-3436, https://doi.org/10.1021/ef7003333.","productDescription":"6 p.","startPage":"3431","endPage":"3436","numberOfPages":"6","costCenters":[],"links":[{"id":240141,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a711de4b0c8380cd7646e","contributors":{"authors":[{"text":"Wei, Z.","contributorId":12675,"corporation":false,"usgs":true,"family":"Wei","given":"Z.","email":"","affiliations":[],"preferred":false,"id":431805,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moldowan, J.M.","contributorId":78527,"corporation":false,"usgs":true,"family":"Moldowan","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":431810,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fago, F.","contributorId":14640,"corporation":false,"usgs":true,"family":"Fago","given":"F.","email":"","affiliations":[],"preferred":false,"id":431806,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dahl, J.E.","contributorId":14641,"corporation":false,"usgs":true,"family":"Dahl","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":431807,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cai, C.","contributorId":75757,"corporation":false,"usgs":true,"family":"Cai","given":"C.","email":"","affiliations":[],"preferred":false,"id":431809,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peters, K.

These rocks were sampled in situ by ROV and lie beneath a complete upper crustal section providing geological context. This is only the second area (after the Hess Deep) in which a substantial depth into the plutonic complex formed at the East Pacific Rise has been sampled in situ and reveals significant spatial heterogeneity in the plutonic complex. In contrast to the uppermost plutonic rocks at Hess Deep, the rocks studied here are generally primitive with olivine forsterite contents mainly between 85 and 88 and including many troctolites. The melt that the majority of the samples crystallized from was aggregated normal mid-ocean ridge basalt (MORB). Despite this high Mg# clinopyroxene is common despite model predictions that clinopyroxene should not reach the liquidus early during low-pressure crystallization of MORB. Stochastic modeling of melt crystallisation at various levels in the crust suggests that it is unlikely that a significant melt mass crystallized in the deeper crust (for example in sills) because this would lead to more evolved shallow level plutonic rocks. Similar to the upper plutonic section at Hess Deep, and in the Oman ophiolite, many samples show a steeply dipping, axis-parallel, magmatic fabric. This suggests that vertical magmatic flow is an important process in the upper part of the seismic low velocity zone beneath fast-spreading ridges. We suggest that both temporal and spatial (along-axis) variability in the magmatic and hydrothermal systems can explain the differences observed between the Hess Deep and Pito Deep plutonics. ??

We use trench mapping and radiometric dating to estimate displacements and timing of the last three surface-rupturing earthquakes (E1-E3) on the southern part of the fault south of Denio, Nevada. Coseismic displacements range from 1.1 to 2.2 ?? 0.5 m, and radiometric ages indicate earthquake times of 11.5 ?? 2.0 ka (E3), 6.1 ?? 0.5 ka (E2), and 4.6 ?? 1.0 ka (E1). These data yield recurrence intervals of 5.4 ?? 2.1 k.y. between E3 and E2, 1.5 ?? 1.1 k.y. between E2 and E1, and an elapsed time of 4.6 ?? 1.0 k.y. since E1. The recurrence data yield variable interval slip rates (between 0.2 ?? 0.22 and 1.5 ?? 2.3 mm/yr), but slip rates averaged over the past ???18 k.y. (0.24 ?? 0.06 mm/year) are similar to long-term (8.5-12.5 Ma) slip rates (0.2 ?? 0.1 mm /yr) measured a few kilometers to the north. We infer from the lack of significant topographic relief across the fault in Bog Hot Valley that the fault zone is propagating southward and may now be connected with a fault at the northwestern end of the Pine Forest Range. Displacements documented in the trench and a rupture length of 37 km indicate a history of three latest Quaternary earthquakes with magnitudes of M 6.6-7.1 on the southern part of the Steens fault zone.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120060202","issn":"00371106","usgsCitation":"Personius, S., Crone, A.J., Machette, M.N., Mahan, S., Kyung, J., Cisneros, H., and Lidke, D., 2007, Late quaternary paleoseismology of the southern Steens fault zone, northern Nevada: Bulletin of the Seismological Society of America, v. 97, no. 5, p. 1662-1678, https://doi.org/10.1785/0120060202.","startPage":"1662","endPage":"1678","numberOfPages":"17","costCenters":[],"links":[{"id":212178,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120060202"},{"id":239628,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"97","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4557e4b0c8380cd67229","contributors":{"authors":[{"text":"Personius, S.

Determining the temporal and spatial patterns of migration and degree of population segregation during migration is critical to understanding long-term population trends of migrant birds. At all five migration sites, we found a significant negative relationship between the date Wilson’s Warblers passed through the sampling station and δD values of their feathers. These data were consistent with a pattern of “leap-frog” migration, in which individuals that bred the previous season at southern latitudes migrated through migration stations earlier than individuals that had previously bred at more northern latitudes. We documented that this pattern was consistent across sites and in multiple years. This finding corroborates previous research conducted on Wilson’s Warbler during the fall migration. In addition, mean δD values became more negative across sampling stations from west to east, with the mean δD values at each station corresponding to different geographic regions of the Wilson’s Warblers’ western breeding range. These data indicate that Wilson’s Warblers passing through each station represented a specific regional subset of the entire Wilson’s Warbler western breeding range. As a result, habitat alterations at specific areas across the east-west expanse of the bird’s migratory route in the southwestern United States could differentially affect Wilson’s Warblers at different breeding areas. This migration information is critical for management of Neotropical migrants, especially in light of the rapid changes presently occurring over the southwestern landscape.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1642/0004-8038(2007)124[162:SATMPO]2.0.CO;2","issn":"00048038","usgsCitation":"Paxton, K., van Riper, C., Theimer, T., and Paxton, E.H., 2007, Spatial and temporal migration patterns of Wilson's Warbler (<i>Wilsonia pusilla</i>) in the southwest as revealed by stable isotopes: The Auk, v. 124, no. 1, p. 162-175, https://doi.org/10.1642/0004-8038(2007)124[162:SATMPO]2.0.CO;2.","productDescription":"14 p.","startPage":"162","endPage":"175","costCenters":[],"links":[{"id":477143,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/0004-8038(2007)124[162:satmpo]2.0.co;2","text":"Publisher Index Page"},{"id":239775,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"124","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b943ce4b08c986b31a95a","contributors":{"authors":[{"text":"Paxton, K.L.","contributorId":78547,"corporation":false,"usgs":true,"family":"Paxton","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":432947,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"van Riper, Charles III 0000-0003-1084-5843 charles_van_riper@usgs.gov","orcid":"https://orcid.org/0000-0003-1084-5843","contributorId":169488,"corporation":false,"usgs":true,"family":"van Riper","given":"Charles","suffix":"III","email":"charles_van_riper@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":false,"id":432946,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Theimer, T.C.","contributorId":31580,"corporation":false,"usgs":true,"family":"Theimer","given":"T.C.","affiliations":[],"preferred":false,"id":432945,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Paxton, E.
