Presented within are geological, geochemical, and mineralogical characteristics that differentiate this deposit type from porphyry copper and alkali-feldspar rhyolite-granite porphyry molybdenum deposits. The U.S. Geological Survey's effort to update existing mineral deposit models spurred this research, which is intended to supplement previously published models for this deposit type that help guide mineral-resource and mineral-environmental assessments.</p>\n<p>Arc-related porphyry molybdenum deposits are a substantial resource for molybdenum metal and may have anomalous concentrations of tungsten. The deposits contain low-grade ore (0.03-0.22 percent molybdenum) as molybdenite, but are large-tonnage, making them amenable to bulk mining open-pit techniques. The mineralizing system usually has fluorine contents of less than 0.1 percent. The cogenetic intrusion is a differentiated calc-alkaline granitoid, typically granodiorite to quartz monzonite in composition, with low rubidium and niobium, and moderate to high strontium concentrations. Metals and hydrothermal fluids are sourced from these intrusions, with an additional meteoric fluid component contributing to peripheral alteration but not adding more metal. The lithology of the surrounding country rocks is not important to the formation of these deposits, but a surrounding carbonate unit may be altered to skarn that contains economic mineralization. The creation of contact-metamorphosed hornfels adjacent to the intrusion is common.</p>\n<p>Formation of arc-related porphyry molybdenum deposits typically occurs within a continental arc environment related to arc-continent or continent-continent collision and subduction. Few deposits are found in an island arc setting. Most classified arc-related porphyry molybdenum deposits are located in the western cordillera of North America, notably in British Columbia and Alaska.</p>\n<p>Hydrothermal alteration provides a key component to the identification of a deposit. Alteration usually is zoned from a core of potassic plus/minus silicic alteration outwards through phyllic to propylitic alteration. Argillic alteration may be irregular in shape and will overprint earlier hydrothermal alteration.</p>\n<p>Exploration should be limited to magmatic arc belts that have been unroofed and eroded to levels of a few kilometers depth. Important geological vectors toward areas of higher grade mineralization include intensity of hydrothermal alteration, veining, and faulting. Anomalous levels of molybdenum, tungsten, copper, lead, or zinc in soils, tills, stream sediments, and drainage waters may indicate the presence of an arc-related porphyry molybdenum deposit. Geophysical exploration techniques have been met with minimal success because of the overall low concentration of associated sulfide and oxide minerals.</p>\n<p>Geoenvironmental concerns are generally low because of low volumes of sulfide minerals. Most deposits are marginally acid-generating to non-acid-generating with drainage waters being near-neutral pH because of the acid generating potential of pyrite being partially buffered by late-stage calcite-bearing veins. The low ore content results in a waste:ore ratio of nearly 1:1 and large tailings piles from the open-pit method of mining.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Mineral deposit models for resource assessment (Scientific Investigations Report 2010-5070)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20105070D","usgsCitation":"Taylor, R.D., Hammarstrom, J.M., Piatak, N., and Seal, R., 2012, Arc-related porphyry molybdenum deposit model: U.S. Geological Survey Scientific Investigations Report 2010-5070, vii, 51 p., https://doi.org/10.3133/sir20105070D.","productDescription":"vii, 51 p.","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":257656,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.er.usgs.gov/thumbnails/sir_2010_5070_D.gif"},{"id":311530,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2010/5070/d/sir2010-5070d.pdf","text":"Report","size":"17.9 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":257655,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2010/5070/d/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ed2ce4b0c8380cd4968a","contributors":{"authors":[{"text":"Taylor, Ryan D. 0000-0002-8845-5290 rtaylor@usgs.gov","orcid":"https://orcid.org/0000-0002-8845-5290","contributorId":3412,"corporation":false,"usgs":true,"family":"Taylor","given":"Ryan","email":"rtaylor@usgs.gov","middleInitial":"D.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":464806,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hammarstrom, Jane M. 0000-0003-2742-3460 jhammars@usgs.gov","orcid":"https://orcid.org/0000-0003-2742-3460","contributorId":1226,"corporation":false,"usgs":true,"family":"Hammarstrom","given":"Jane","email":"jhammars@usgs.gov","middleInitial":"M.","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":387,"text":"Mineral Resources Program","active":true,"usgs":true}],"preferred":true,"id":464805,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Piatak, Nadine M.","contributorId":23621,"corporation":false,"usgs":true,"family":"Piatak","given":"Nadine M.","affiliations":[],"preferred":false,"id":464807,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Seal, Robert R.

Results of the analyses in water showed the treatment resulted in a maximum concentration of 1.14 mg/L TFM. Residues of TFM in water were greatest 50 m east of the mouth (0.73 mg/L TFM) and had decreased below detection at most of the sampling sites one day after treatment. Residues of TFM in sediment were greatest 50 m east of the mouth (105 ng/g TFM) with lower levels observed west of the mouth (3-5 ng/g TFM) the day of the treatment. Residues decreased rapidly and were below detection in most of the samples the day after treatment. Residues of TFM in caged mayflies were greatest one day after treatment (3,193 ng/g wet weight), decreased substantially by 4 days after treatment (74 ng/g), but were still present 8 days after treatment (80 ng/g). Based on results from this study the overall TFM exposure to adult piping plovers (0.425 mg/kg) was 85 times less than the estimated No Observable Effects Concentration (NOEC) of 36 mg/kg and was 17 times less than the NOEC for plover chicks (2.13 mg/kg) indicating the risk from sea lamprey control operations would likely be minimal.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jglr.2012.01.009","usgsCitation":"Boogaard, M.A., Hubert, T.D., Bernardy, J.A., Kaye, C.A., and Baldwin, G.A., 2012, Evaluation of 3-trifluoromethyl-4-nitrophenol (TFM) residues following a lampricide treatment as a risk assessment to the endangered piping plover: Journal of Great Lakes Research, v. 38, no. 2, p. 362-367, https://doi.org/10.1016/j.jglr.2012.01.009.","productDescription":"5 p.","startPage":"362","endPage":"367","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":257803,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257797,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1016/j.jglr.2012.01.009","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Michigan","county":"Luce","volume":"38","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c0ce4b0c8380cd529f3","contributors":{"authors":[{"text":"Boogaard, Michael A. 0000-0002-5192-8437 mboogaard@usgs.gov","orcid":"https://orcid.org/0000-0002-5192-8437","contributorId":865,"corporation":false,"usgs":true,"family":"Boogaard","given":"Michael","email":"mboogaard@usgs.gov","middleInitial":"A.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":463057,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hubert, Terrance D. 0000-0001-9712-1738 thubert@usgs.gov","orcid":"https://orcid.org/0000-0001-9712-1738","contributorId":3036,"corporation":false,"usgs":true,"family":"Hubert","given":"Terrance","email":"thubert@usgs.gov","middleInitial":"D.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":463058,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bernardy, Jeffry A. 0000-0001-7443-1995 jbernardy@usgs.gov","orcid":"https://orcid.org/0000-0001-7443-1995","contributorId":3537,"corporation":false,"usgs":true,"family":"Bernardy","given":"Jeffry","email":"jbernardy@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":463059,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kaye, Cheryl A.","contributorId":68693,"corporation":false,"usgs":true,"family":"Kaye","given":"Cheryl","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":463061,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Baldwin, Gregg A.","contributorId":22734,"corporation":false,"usgs":true,"family":"Baldwin","given":"Gregg","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":463060,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The sulfide mineralization consists principally of galena and sphalerite and occurs as open-space fillings of voids and moderate to massive replacement of the medium- to coarse-grained host dolostone. Five types of dolomite have been distinguished, two of which (D<sub>1</sub> and D<sub>2</sub>) are of replacement origin, whereas HD<sub>1</sub>, HD<sub>2</sub>, HD<sub>3</sub> occurring as open-space filling are of hydrothermal affiliation. Main ore controls include stratigraphy and lithology, carbonate dissolution, paleogeography, faults or faulted rocks, and availability of organic matter. Fluid inclusion data, along with Na-Cl-Br leachate, indicate that the ore-forming fluids correspond to evolved NaCl-CaCl<sub>2</sub>-KCl-MgCl<sub>2</sub> basin-derived hot (100&deg; &plusmn; 20&deg;C) saline brines (>20 wt % NaCl equiv) that acquired their high salinities and Ca/Na ratios through evaporation of seawater, and subsequent dolomitization and fluid-rock interactions. Stable isotope data for replacement and hydrothermal dolomites are tightly clustered and overlapping, with &delta;<sup>18</sup>O and &delta;<sup>13</sup>C values from 20.5 to 21.2 and 0.2 to 0.7&permil;, respectively. Similarly, sulfides yield &delta;<sup>34</sup>S values between 11.2 and 1.9&permil;, whereas those corresponding to the nearby Triassic gypsum cluster yield around 14&permil;. Altogether, these isotopic compositions are consistent with a basinal-type fluid with reduced sulfur very likely being derived through thermochemical reduction of dissolved sulfate, resulting in metal precipitation, and carbon of mainly marine Aalenian-Bajocian carbonate origin with a minor biogenic component. <sup>87</sup>Sr/<sup>86</sup>Sr values of replacement dolostone are similar to those of ore-related hydrothermal dolomites, ranging from 0.70746 to 0.70833 and from 0.70769 to 0.70828, respectively, and are different from those of the Visean rhyodacite (0.71849&ndash;0.72167).

The intimate link between faults and mineralization suggests the strong possibility of brine flow along both ENE-trending regional-scale faults and NW-SW-trending local-scale faults. The data suggest that MVT mineralization was emplaced during the late Neogene-Quaternary (i.e., ca. 15&ndash;0 Ma), possibly as a result of subsurface gravity-driven fluid flow in response to the collision between the African and Eurasian plates.","language":"English","publisher":"Society of Economic Geologists","publisherLocation":"Littleton, CO","doi":"10.2113/econgeo.107.1.117","usgsCitation":"Bouabdellah, M., Sangster, D.F., Leach, D.L., Brown, A.C., Johnson, C.A., and Emsbo, P., 2012, Genesis of the Touissit-Bou Beker Mississippi Valley-type district (Morocco-Algeria) and its relation to the Africa-Europe collision: Economic Geology, v. 107, no. 1, p. 117-146, https://doi.org/10.2113/econgeo.107.1.117.","productDescription":"30 p,","startPage":"117","endPage":"146","ipdsId":"IP-031162","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":257630,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Algeria, Morocco","otherGeospatial":"Touissit-bou Beker District","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -9.0966796875,\n              29.11377539511439\n            ],\n            [\n              -1.3842773437499998,\n              29.11377539511439\n            ],\n            [\n              -1.3842773437499998,\n              35.746512259918504\n            ],\n            [\n              -9.0966796875,\n              35.746512259918504\n            ],\n            [\n              -9.0966796875,\n              29.11377539511439\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"107","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-01-13","publicationStatus":"PW","scienceBaseUri":"505a155ce4b0c8380cd54d9a","contributors":{"authors":[{"text":"Bouabdellah, Mohammed","contributorId":71818,"corporation":false,"usgs":true,"family":"Bouabdellah","given":"Mohammed","email":"","affiliations":[],"preferred":false,"id":356401,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sangster, Donald F.","contributorId":7124,"corporation":false,"usgs":false,"family":"Sangster","given":"Donald","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":356400,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leach, David L.","contributorId":83902,"corporation":false,"usgs":true,"family":"Leach","given":"David","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":356402,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brown, Alex C.","contributorId":102730,"corporation":false,"usgs":true,"family":"Brown","given":"Alex","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":356403,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Johnson, Craig A. 0000-0002-1334-2996 cjohnso@usgs.gov","orcid":"https://orcid.org/0000-0002-1334-2996","contributorId":909,"corporation":false,"usgs":true,"family":"Johnson","given":"Craig","email":"cjohnso@usgs.gov","middleInitial":"A.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true},{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":356398,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Emsbo, Poul 0000-0001-9421-201X pemsbo@usgs.gov","orcid":"https://orcid.org/0000-0001-9421-201X","contributorId":997,"corporation":false,"usgs":true,"family":"Emsbo","given":"Poul","email":"pemsbo@usgs.gov","affiliations":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":356399,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Calibrated groundwater-flow models and a variable-advection particle-tracking scheme that accounts for uncertainty were used to derive ranges of conservative solute concentration and groundwater age within spatially defined zones from solute loading to the water table. Aquifers were partitioned into six zones; four relative depth zones and two zones to represent pumping wells and surface water. Five years after solute was introduced in simulated recharge and stream leakage, normalized zone concentrations were detected at values above 10<sup>-4</sup> in the shallowest aquifer zone, well zone, and surface-water zone for 10 of the 11 study areas. At the 125-year time scale, 9 out of the 11 study areas exhibited detectable concentrations in all zones and the majority of zones possess concentrations that are substantial relative to the source concentration (<i>ClC<sub>o</sub></i> > 10-1). Thresholds defined by the time representing the earliest 1% of groundwater-transit times were used to identify fast transport pathways within the groundwater. The 1% thresholds occurred in a period of days to years for the shallow zone, days to decades for the well and surface-water zones, and years to millennia for the deeper zones. Thresholds defined by the 99th percentile of groundwater travel times were used to reflect late-time response and ranged considerably between study area (~10<sup>2</sup> to ~10<sup>6</sup> years), which highlights the potential for chemical constituents to persist in groundwater for long periods under a conservative state. The results of this investigation provide an instructive example of the intricate relations between climate and aquifer characteristics and their role on solute transport in groundwater. The proposed method accounts for dynamical processes in the aquifer and complements more traditional assessments of susceptibility using (apparent) mean water age.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jhydrol.2012.03.012","usgsCitation":"Wellman, T., Kauffman, L., and Clark, B., 2012, A zonal evaluation of intrinsic susceptibility in selected principal aquifers of the United States: Journal of Hydrology, v. 440-441, p. 36-51, https://doi.org/10.1016/j.jhydrol.2012.03.012.","productDescription":"16 p.","startPage":"36","endPage":"51","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"links":[{"id":257648,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257642,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2012.03.012","linkFileType":{"id":5,"text":"html"}}],"country":"United States","volume":"440-441","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e622e4b0c8380cd471a3","contributors":{"authors":[{"text":"Wellman, Tristan P.","contributorId":56500,"corporation":false,"usgs":true,"family":"Wellman","given":"Tristan P.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":false,"id":356723,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kauffman, Leon","contributorId":98992,"corporation":false,"usgs":true,"family":"Kauffman","given":"Leon","affiliations":[],"preferred":false,"id":356724,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Clark, Brian","contributorId":29260,"corporation":false,"usgs":true,"family":"Clark","given":"Brian","affiliations":[],"preferred":false,"id":356722,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The post audit is based on a paired synoptic approach in which hydrogeochemical data are collected at low (existing conditions) and elevated (following treatment) pH. Data obtained under existing, low-pH conditions are used for calibration, and the resultant model is used to predict metal concentrations observed following treatment. Predictions for Al, As, Fe, H<sup>+</sup>, and Pb accurately reproduce the observed reduction in dissolved concentrations afforded by the treatment system, and the information provided in regard to standard attainment is also accurate (predictions correctly indicate attainment or nonattainment of water quality standards for 19 of 25 cases). Errors associated with Cd, Cu, and Zn are attributed to misspecification of sorbent mass (precipitated Fe). In addition to these specific results, the post audit provides insight in regard to calibration and sensitivity analysis that is contrary to conventional wisdom. Steps taken during the calibration process to improve simulations of As sorption were ultimately detrimental to the predictive results, for example, and the sensitivity analysis failed to bracket observed metal concentrations.","language":"English","publisher":"ACS Publications","publisherLocation":"Washington, D.C.","doi":"10.1021/es2038504","usgsCitation":"Runkel, R.L., Kimball, B.A., Walton-Day, K., Verplanck, P.L., and Broshears, R.E., 2012, Evaluating remedial alternatives for an acid mine drainage stream: A model post audit: Environmental Science & Technology, v. 46, no. 1, p. 340-347, https://doi.org/10.1021/es2038504.","productDescription":"8 p.","startPage":"340","endPage":"347","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true}],"links":[{"id":257646,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"Mineral Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -107.73133277893065,\n              37.87227881950715\n            ],\n            [\n              -107.73133277893065,\n              37.890976310542925\n            ],\n            [\n              -107.7088451385498,\n              37.890976310542925\n            ],\n            [\n              -107.7088451385498,\n              37.87227881950715\n            ],\n            [\n              -107.73133277893065,\n              37.87227881950715\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"46","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-12-14","publicationStatus":"PW","scienceBaseUri":"505a0bf1e4b0c8380cd52961","contributors":{"authors":[{"text":"Runkel, Robert L. 0000-0003-3220-481X runkel@usgs.gov","orcid":"https://orcid.org/0000-0003-3220-481X","contributorId":685,"corporation":false,"usgs":true,"family":"Runkel","given":"Robert","email":"runkel@usgs.gov","middleInitial":"L.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":513478,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kimball, Briant A. bkimball@usgs.gov","contributorId":533,"corporation":false,"usgs":true,"family":"Kimball","given":"Briant","email":"bkimball@usgs.gov","middleInitial":"A.","affiliations":[{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true}],"preferred":true,"id":513477,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Walton-Day, Katherine 0000-0002-9146-6193","orcid":"https://orcid.org/0000-0002-9146-6193","contributorId":68339,"corporation":false,"usgs":true,"family":"Walton-Day","given":"Katherine","affiliations":[],"preferred":false,"id":513481,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Verplanck, Philip L. 0000-0002-3653-6419 plv@usgs.gov","orcid":"https://orcid.org/0000-0002-3653-6419","contributorId":728,"corporation":false,"usgs":true,"family":"Verplanck","given":"Philip","email":"plv@usgs.gov","middleInitial":"L.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":513479,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Broshears, Robert E.","contributorId":40675,"corporation":false,"usgs":true,"family":"Broshears","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":513480,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

For the Global Seismographic Network (Butler et al., 2004), as well as many other networks, this instrument response is represented as a Laplace domain pole&ndash;zero model and published in the Standard for the Exchange of Earthquake Data (SEED) format. This Laplace representation assumes that the seismometer behaves as a linear system, with any abrupt changes described adequately via multiple time-invariant epochs. The SEED format allows for published instrument response errors as well, but these typically have not been estimated or provided to users. We present an iterative three-step method to estimate the instrument response parameters (poles and zeros) and their associated errors using random calibration signals. First, we solve a coarse nonlinear inverse problem using a least-squares grid search to yield a first approximation to the solution. This approach reduces the likelihood of poorly estimated parameters (a local-minimum solution) caused by noise in the calibration records and enhances algorithm convergence. Second, we iteratively solve a nonlinear parameter estimation problem to obtain the least-squares best-fit Laplace pole&ndash;zero&ndash;gain model. Third, by applying the central limit theorem, we estimate the errors in this pole&ndash;zero model by solving the inverse problem at each frequency in a two-thirds octave band centered at each best-fit pole&ndash;zero frequency. This procedure yields error estimates of the 99% confidence interval. We demonstrate the method by applying it to a number of recent Incorporated Research Institutions in Seismology/United States Geological Survey (IRIS/USGS) network calibrations (network code IU).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","publisherLocation":"El Cerrito, CA","doi":"10.1785/0120110195","usgsCitation":"Ringler, A., Hutt, C., Aster, R., Bolton, H., Gee, L., and Storm, T., 2012, Estimating pole/zero errors in GSN-IRIS/USGS network calibration metadata: Bulletin of the Seismological Society of America, v. 102, no. 2, p. 836-841, https://doi.org/10.1785/0120110195.","productDescription":"6 p.","startPage":"836","endPage":"841","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":257633,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257628,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120110195","linkFileType":{"id":5,"text":"html"}}],"volume":"102","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-03-29","publicationStatus":"PW","scienceBaseUri":"505a0b38e4b0c8380cd52616","contributors":{"authors":[{"text":"Ringler, A.

Data were collected as part of a long-term monitoring program conducted by Montana Fish, Wildlife and Parks to primarily estimate rainbow (Oncorhynchus mykiss) and brown trout (Salmo trutta) abundance in numerous rivers across Montana. We used a hierarchical Bayesian mark-recapture model to estimate fish abundance over time in each of the three river reaches. We then fit a state-space Gompertz model to estimate current trends and future fish populations. Density dependent effects were detected in 1 of the 6 fish populations. Predictions of future fish populations displayed wide credible intervals. Our simulations indicated that given the observed variation in the abundance estimates, the probability of detecting a 30% decline in fish populations over a five-year period was less than 50%. We recommend a monitoring program that is closely tied to management objectives and reflects the precision necessary to make informed management decisions.","language":"English","publisher":"Bentham Open","publisherLocation":"Oak Park, IL","doi":"10.2174/1874401X01205010001","usgsCitation":"Russell, R.E., Schmetterling, D.A., Guy, C.S., Shepard, B.B., McFarland, R., and Skaar, D., 2012, Evaluating a fish monitoring protocol using state-space hierarchical models: Open Fish Science Journal, v. 5, p. 1-8, https://doi.org/10.2174/1874401X01205010001.","productDescription":"8 p.","startPage":"1","endPage":"8","ipdsId":"IP-030676","costCenters":[{"id":398,"text":"Montana Cooperative Fishery Research Unit","active":false,"usgs":true},{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":474459,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2174/1874401x01205010001","text":"Publisher Index Page"},{"id":257644,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257639,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2174/1874401X01205010001","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Montana","volume":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0bd8e4b0c8380cd528e5","contributors":{"authors":[{"text":"Russell, Robin E. 0000-0001-8726-7303 rerussell@usgs.gov","orcid":"https://orcid.org/0000-0001-8726-7303","contributorId":3998,"corporation":false,"usgs":true,"family":"Russell","given":"Robin","email":"rerussell@usgs.gov","middleInitial":"E.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":351213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schmetterling, David A.","contributorId":20223,"corporation":false,"usgs":true,"family":"Schmetterling","given":"David","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":351214,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guy, Chris S.","contributorId":87423,"corporation":false,"usgs":true,"family":"Guy","given":"Chris","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":351216,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shepard, Bradley B.","contributorId":57327,"corporation":false,"usgs":true,"family":"Shepard","given":"Bradley","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":351215,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McFarland, Robert","contributorId":87822,"corporation":false,"usgs":true,"family":"McFarland","given":"Robert","email":"","affiliations":[],"preferred":false,"id":351217,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Skaar, Donald","contributorId":99008,"corporation":false,"usgs":true,"family":"Skaar","given":"Donald","affiliations":[],"preferred":false,"id":351218,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

In many organisms, sex-biased dispersal is related to the type of mating system. Considerably less is known about the influence of life history variability on dispersal. Here we investigated patterns of dispersal in masu salmon (Oncorhynchus masou) to evaluate influences of sex and life history on dispersal. As expected, assignment tests and isolation by distance analysis revealed that dispersal of marine-migratory masu salmon was male-biased. However, dispersal of resident and migratory males did not follow our expectation and marine-migratory individuals dispersed more than residents. This may be because direct competition between marine-migratory and resident males is weak or that the cost of dispersal is smaller for marine-migratory individuals. This study revealed that both sex and migratory life history influence patterns of dispersal at a local scale in masu salmon.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology and Evolution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1002/ece3.228","usgsCitation":"Kitanishi, S., Yamamoto, T., Koizumi, I., Dunham, J., and Higashi, S., 2012, Fine scale relationships between sex, life history, and dispersal of masu salmon: Ecology and Evolution, v. 2, no. 5, p. 920-929, https://doi.org/10.1002/ece3.228.","productDescription":"10 p.","startPage":"920","endPage":"929","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":474457,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ece3.228","text":"Publisher Index Page"},{"id":257615,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257609,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/ece3.228","linkFileType":{"id":5,"text":"html"}}],"volume":"2","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-04-08","publicationStatus":"PW","scienceBaseUri":"505a1021e4b0c8380cd53b37","contributors":{"authors":[{"text":"Kitanishi, Shigeru","contributorId":26589,"corporation":false,"usgs":true,"family":"Kitanishi","given":"Shigeru","email":"","affiliations":[],"preferred":false,"id":464385,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yamamoto, Toshiaki","contributorId":60506,"corporation":false,"usgs":true,"family":"Yamamoto","given":"Toshiaki","email":"","affiliations":[],"preferred":false,"id":464388,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Koizumi, Itsuro","contributorId":39658,"corporation":false,"usgs":true,"family":"Koizumi","given":"Itsuro","email":"","affiliations":[],"preferred":false,"id":464387,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dunham, Jason B.","contributorId":64791,"corporation":false,"usgs":true,"family":"Dunham","given":"Jason B.","affiliations":[],"preferred":false,"id":464389,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Higashi, Seigo","contributorId":35607,"corporation":false,"usgs":true,"family":"Higashi","given":"Seigo","email":"","affiliations":[],"preferred":false,"id":464386,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We considered variable-density groundwater flow in a 1500-km-long and approximately 10-km-deep cross-section through southern Sweden. Groundwater flow and shield brine transport in the cross-sectional model were analyzed under projected surface conditions for the next 140 ka. Simulations suggest that blockage of recharge and discharge by low-permeability permafrost or cold-based ice causes sinking of brine and consequent freshening of near-surface water in areas of natural discharge. Although recharge of basal meltwater is limited by the requirement that water pressure at the base of the ice sheet not exceed the pressure exerted by the weight of the ice, warm-based ice with basal melting creates a potential for groundwater recharge rates much larger than those of present, ice-free conditions. In the simulations, regional-scale redistribution of recharged water by subsurface flow is minor over the duration of a glacial advance (approximately 10 ka). During glacial retreat, significant upward flow of groundwater may occur below the ice sheet owing to pressure release. If the mechanical loading efficiency of the rocks is high, both subsurface penetration of meltwater during glacial advance and up-flow during glacial retreat are reduced because of loading-induced pressure changes. The maximum rate of groundwater discharge in the simulations occurs at the receding ice margin, and some discharge occurs below incursive postglacial seas. Recharge of basal meltwater could decrease the concentration of dissolved solids significantly below present-day levels at depths of up to several kilometers and may bring oxygenated conditions to an otherwise reducing chemical environment for periods exceeding 10 ka.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geofluids","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1468-8123.2012.00361.x","usgsCitation":"Provost, A., Voss, C., and Neuzil, C., 2012, Glaciation and regional groundwater flow in the Fennoscandian shield: Geofluids, v. 12, no. 1, p. 79-96, https://doi.org/10.1111/j.1468-8123.2012.00361.x.","productDescription":"18","startPage":"79","endPage":"96","costCenters":[{"id":494,"text":"Office of Groundwater","active":false,"usgs":true}],"links":[{"id":257634,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257624,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1468-8123.2012.00361.x","linkFileType":{"id":5,"text":"html"}}],"country":"Sweden","otherGeospatial":"Fennoscandian Shield","volume":"12","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-02-20","publicationStatus":"PW","scienceBaseUri":"505a290ee4b0c8380cd5a64a","contributors":{"authors":[{"text":"Provost, A.M.","contributorId":16098,"corporation":false,"usgs":true,"family":"Provost","given":"A.M.","affiliations":[],"preferred":false,"id":354162,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Voss, C.I.","contributorId":79515,"corporation":false,"usgs":true,"family":"Voss","given":"C.I.","email":"","affiliations":[],"preferred":false,"id":354163,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Neuzil, C.

However, many such studies fail to also consider the influence of natural threats, a variable environment, and parental roles. Our work examines interactive relationships of cyclical (time of day, tide, temperature, seasonality) and stochastic (natural/human disturbance) processes with incubation patterns (attendance, bout lengths, recess rates) of the Black Oystercatcher (Haematopus bachmani), a shorebird of conservation concern. We used 24-hour-per-day video monitoring of 13 molecularly-sexed breeding pairs to systematically examine incubation, revealing previously undocumented information that may inform conservation practices for the genus. Seven of 22 video-monitored nests failed, primarily from egg depredation by nocturnally-active mammals. Analyses of 3177 hrs of video footage indicated a near doubling of incubation bout lengths at night, corresponding to the increased risk of nighttime egg predation. Females had higher overall nest attendance (54% vs. 42%) and longer mean incubation bout lengths than males (88 min vs. 73 min). Uninterrupted incubation bouts were over twice as long as bouts interrupted by disturbance. Incubating males departed nests substantially more frequently due to nest-area disturbances than females in one, but not both, years of our study. Our findings suggest that sexes exhibit different, but complimentary, incubation patterns, facilitating efficient egg care in a dynamic environment with several nest threats. We emphasize the importance of considering natural influences when evaluating human threats to shorebird reproductive behavior and success.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"The Condor","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Cooper Ornithological Society","publisherLocation":"Waco, TX","doi":"10.1525/cond.2011.100094","usgsCitation":"Spiegel, C.S., Haig, S.M., Goldstein, M.I., and Huso, M.M., 2012, Factors affecting incubation patterns and sex roles of black oystercatchers in Alaska: The Condor, v. 114, no. 1, p. 123-134, https://doi.org/10.1525/cond.2011.100094.","productDescription":"12 p.","startPage":"123","endPage":"134","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":474455,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/cond.2011.100094","text":"Publisher Index Page"},{"id":257614,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257608,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1525/cond.2011.100094","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","volume":"114","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0ea3e4b0c8380cd53553","contributors":{"authors":[{"text":"Spiegel, Caleb S.","contributorId":43213,"corporation":false,"usgs":true,"family":"Spiegel","given":"Caleb","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":463134,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haig, Susan M. 0000-0002-6616-7589 susan_haig@usgs.gov","orcid":"https://orcid.org/0000-0002-6616-7589","contributorId":719,"corporation":false,"usgs":true,"family":"Haig","given":"Susan","email":"susan_haig@usgs.gov","middleInitial":"M.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":true,"id":463132,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goldstein, Michael I.","contributorId":94641,"corporation":false,"usgs":true,"family":"Goldstein","given":"Michael","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":463135,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Huso, Manuela M.

The river originates on the northern slope of the world's tallest mountains, the Himalaya Range, and then drops elevation quickly through steep mountain gorges, tumbling out of China into Myanmar (Burma) and the Lao People's Democratic Republic (Lao PDR). The precipitous terrain of Lao PDR and Thailand generates interest in the river and its tributaries for hydropower development. The terrain, soils, water, and climate make it one of the world's most biologically rich regions. The Mekong's bounty is again on display in the Mekong River Delta, where rice production has successfully been increased to high levels making Vietnam second only to Thailand as the world's largest rice exporters. At least 800 fish species contribute to the natural resource bounty of the Mekong River and are the basis for one of the world's most productive fisheries that provide the primary protein source to more than 50 million people. Against this backdrop of rich natural resources, the U.S. Geological Survey (USGS) is working with the consulting firm FISHBIO, colleagues from the international Delta Research and Global Observation Network (DRAGON) Institute, and a broad contingent of Southeast Asian representatives and partners from abroad to increase knowledge of the Mekong River fisheries and to develop the capacity of permanent residents to investigate and understand these fisheries resources. With the Lower Mekong Basin (LMB) region facing the likelihood of significant environmental changes as a result of both human activities and global climate change, enhancing environmental understanding is critical. To encourage cooperation among the LMB scientists and managers in the study of the Mekong River's fisheries, FISHBIO and the USGS, with generous support from the U.S. State Department, hosted a workshop in Phnom Penh, Cambodia, in February 2012. Workshop participants were from Lao PDR, Thailand, Cambodia, and Vietnam. Representatives from the governments, universities, nongovernmental organizations, and the Mekong River Commission discussed current and potential methods and mechanisms of the Mekong Fish Monitoring Network. The goals of the workshop were to determine if the Network and associated databases were of interest and value to the LMB nations, to determine if future fisheries monitoring data would be comparable among the nations, and to establish methods and an organizational structure for collaborating on future monitoring and research. The participants in this international workshop agreed that the Network would be useful but would require additional funding to secure their full participation. The USGS and FISHBIO are collaboratively seeking additional funding to expand research participation and projects in all four LMB nations. If the Network can facilitate cooperation among many fisheries researchers in the LMB, the basin would become a model of cooperative international fishery studies and would increase the understanding of a river basin rich in natural resources.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs20123081","usgsCitation":"Andersen, M.E., and Ainsley, S.M., 2012, February 2012 workshop jumpstarts the Mekong Fish Monitoring Network: U.S. Geological Survey Fact Sheet 2012-3081, 4 p., https://doi.org/10.3133/fs20123081.","productDescription":"4 p.","onlineOnly":"Y","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":257635,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_2012_3081.gif"},{"id":257625,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/2012/3081/","linkFileType":{"id":5,"text":"html"}}],"country":"Cambodia;China;Laos;Myanmar (burma);Thailand","city":"Phnom Penh","otherGeospatial":"Mekong River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 88.5,8.5 ], [ 88.5,32.5 ], [ 111.5,32.5 ], [ 111.5,8.5 ], [ 88.5,8.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0f47e4b0c8380cd5384e","contributors":{"authors":[{"text":"Andersen, Matthew E. 0000-0003-4115-5028 mandersen@usgs.gov","orcid":"https://orcid.org/0000-0003-4115-5028","contributorId":3190,"corporation":false,"usgs":true,"family":"Andersen","given":"Matthew","email":"mandersen@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":464792,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ainsley, Shaara M.","contributorId":107973,"corporation":false,"usgs":true,"family":"Ainsley","given":"Shaara","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":464793,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This observation led to the question of how such loss of biological diversity will alter the functioning of ecosystems and their ability to provide society with the goods and services needed to prosper.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Nature Publishing Group","publisherLocation":"London, U.K.","doi":"10.1038/nature11148","usgsCitation":"Cardinale, B., Duffy, J.E., Gonzalez, A., Hooper, D.U., Perrings, C., Venail, P., Narwani, A., Mace, G.M., Tilman, D., Wardle, D.A., Kinzig, A.P., Daily, G.C., Loreau, M., Grace, J.B., Larigauderie, A., Srivastava, D.S., and Naeem, S., 2012, Biodiversity loss and its impact on humanity: Nature, v. 486, no. 7401, p. 59-67, https://doi.org/10.1038/nature11148.","productDescription":"9 p.","startPage":"59","endPage":"67","numberOfPages":"8","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":474460,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://archive-ouverte.unige.ch/unige:28389","text":"External Repository"},{"id":257598,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257590,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/nature11148","linkFileType":{"id":5,"text":"html"}}],"otherGeospatial":"Earth","volume":"486","issue":"7401","noUsgsAuthors":false,"publicationDate":"2012-06-06","publicationStatus":"PW","scienceBaseUri":"5059f14ae4b0c8380cd4ab70","contributors":{"authors":[{"text":"Cardinale, Bradley J.","contributorId":67350,"corporation":false,"usgs":true,"family":"Cardinale","given":"Bradley J.","affiliations":[],"preferred":false,"id":464735,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Duffy, J.

To investigate the effect of study design on landscape genetics inference, we used a spatially-explicit, individual-based program to simulate gene flow in a spatially continuous population inhabiting a landscape with gradual spatial changes in resistance to movement. We simulated a wide range of combinations of number of loci, number of alleles per locus and number of individuals sampled from the population. We assessed how these three aspects of study design influenced the statistical power to successfully identify the generating process among competing hypotheses of isolation-by-distance, isolation-by-barrier, and isolation-by-landscape resistance using a causal modelling approach with partial Mantel tests. We modelled the statistical power to identify the generating process as a response surface for equilibrium and non-equilibrium conditions after introduction of isolation-by-landscape resistance. All three variables (loci, alleles and sampled individuals) affect the power of causal modelling, but to different degrees. Stronger partial Mantel <i>r</i> correlations between landscape distances and genetic distances were found when more loci were used and when loci were more variable, which makes comparisons of effect size between studies difficult. Number of individuals did not affect the accuracy through mean equilibrium partial Mantel <i>r</i>, but larger samples decreased the uncertainty (increasing the precision) of equilibrium partial Mantel <i>r</i> estimates. We conclude that amplifying more (and more variable) loci is likely to increase the power of landscape genetic inferences more than increasing number of individuals.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Molecular Ecology Resources","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1755-0998.2011.03077.x","usgsCitation":"Landguth, E.L., Gedy, B.C., Oyler-McCance, S.J., Garey, A.L., Emel, S.L., Mumma, M., Wagner, H.H., Fortin, M., and Cushman, S., 2012, Effects of sample size, number of markers, and allelic richness on the detection of spatial genetic pattern: Molecular Ecology Resources, v. 12, no. 2, p. 276-284, https://doi.org/10.1111/j.1755-0998.2011.03077.x.","productDescription":"9 p.","startPage":"276","endPage":"284","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":257600,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257589,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1755-0998.2011.03077.x","linkFileType":{"id":5,"text":"html"}}],"volume":"12","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-10-02","publicationStatus":"PW","scienceBaseUri":"505a07bce4b0c8380cd517df","contributors":{"authors":[{"text":"Landguth, Erin L.","contributorId":69002,"corporation":false,"usgs":true,"family":"Landguth","given":"Erin","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":350292,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gedy, Bradley C.","contributorId":44023,"corporation":false,"usgs":true,"family":"Gedy","given":"Bradley","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":350291,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Oyler-McCance, Sara J. 0000-0003-1599-8769 sara_oyler-mccance@usgs.gov","orcid":"https://orcid.org/0000-0003-1599-8769","contributorId":1973,"corporation":false,"usgs":true,"family":"Oyler-McCance","given":"Sara","email":"sara_oyler-mccance@usgs.gov","middleInitial":"J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":350286,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garey, Andrew L.","contributorId":74621,"corporation":false,"usgs":true,"family":"Garey","given":"Andrew","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":350293,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Emel, Sarah L.","contributorId":20200,"corporation":false,"usgs":true,"family":"Emel","given":"Sarah","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":350288,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mumma, Matthew","contributorId":102731,"corporation":false,"usgs":true,"family":"Mumma","given":"Matthew","affiliations":[],"preferred":false,"id":350294,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Wagner, Helene H.","contributorId":12309,"corporation":false,"usgs":true,"family":"Wagner","given":"Helene","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":350287,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Fortin, Marie-Josée","contributorId":40462,"corporation":false,"usgs":true,"family":"Fortin","given":"Marie-Josée","affiliations":[],"preferred":false,"id":350289,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Cushman, Samuel A.","contributorId":41273,"corporation":false,"usgs":true,"family":"Cushman","given":"Samuel A.","affiliations":[],"preferred":false,"id":350290,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

The dataset contains spatial and tabular data related to Bureau of Land Management (BLM) Grazing Allotments. We reviewed the BLM national grazing allotment spatial dataset available from the GeoCommunicator National Integrated Land System (NILS) website in 2007 (http://www.geocommunicator.gov). We identified several limitations in those data and learned that some BLM State and/or field offices had updated their spatial data to rectify these limitations, but maintained the data outside of NILS. We contacted appropriate BLM offices (State or field, 25 in all) to obtain the most recent data, assessed the data, established a data development protocol, and compiled data into a topologically enforced dataset throughout the area of interest for this project (that is, the pre-settlement distribution of Greater Sage-Grouse in the Western United States). The final database includes three spatial datasets: Allotments (BLM Grazing Allotments), OUT_Polygons (nonallotment polygons used to ensure topology), and Duplicate_Polygon_Allotments. See Appendix 1 of the aforementioned report for complete methods. The tabular data presented here consists of information synthesized by the Land Health Standard (LHS) analysis (Appendix 2), and data obtained from the BLM Rangeland Administration System (http://www.blm.gov/ras/). In 2008, available LHS data for all allotments in all regions were compiled by BLM in response to a Freedom of Information Act (FOIA) request made by a private organization. The BLM provided us with a copy of these data. These data provided three major types of information that were of interest: (1) date(s) (if any) of the most recent LHS evaluation for each allotment; (2) whether if evaluated, each region-specific standard (3&ndash;8 LHS depending on region) had been met on a given allotment; and (3) whether livestock contributed to any of these standards not being met. A description of how we processed the original data to prepare for analysis is described in Appendix 2, and the synthesized dataset can be found in the table \"lhs_x_walk.\" Permitted use dates, livestock type (horse, sheep or cattle), number of livestock, and Animal Unit Months [the number of animal units (1,000-pound animal equivalents) that can be grazed for 31 days with the available forage in a sustainable manner] are the legal maximum grazing amounts for a given allotment, and legal adjustments to these numbers occur infrequently. We summarized permitted use by BLM allotment in the table \"Permitted_Use.\" Billed use records are used for calculations of permittees' annual grazing bills. We summarized billed use by allotment for BLM grazing year in the table \"Billed_Use.\" All three tables can be joined with the allotment spatial data in a geographic information system (GIS) environment, using the IDENT attribute as the primary key.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ds690","usgsCitation":"Assal, T., Veblen, K., Farinha, M., Aldridge, C.L., Casazza, M.L., and Pyke, D., 2012, Data resources for range-wide assessment of livestock grazing across the sagebrush biome: U.S. Geological Survey Data Series 690, HTML Document; Downloads Directory, https://doi.org/10.3133/ds690.","productDescription":"HTML Document; Downloads Directory","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":257585,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ds_690.png"},{"id":257584,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/ds/690/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fdb7e4b0c8380cd4e938","contributors":{"authors":[{"text":"Assal, T.J.","contributorId":93596,"corporation":false,"usgs":true,"family":"Assal","given":"T.J.","affiliations":[],"preferred":false,"id":464745,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Veblen, K.E.","contributorId":94537,"corporation":false,"usgs":true,"family":"Veblen","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":464746,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Farinha, M.A.","contributorId":76146,"corporation":false,"usgs":true,"family":"Farinha","given":"M.A.","affiliations":[],"preferred":false,"id":464744,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Aldridge, Cameron L. 0000-0003-3926-6941 aldridgec@usgs.gov","orcid":"https://orcid.org/0000-0003-3926-6941","contributorId":191773,"corporation":false,"usgs":true,"family":"Aldridge","given":"Cameron","email":"aldridgec@usgs.gov","middleInitial":"L.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":464742,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Casazza, Michael L. 0000-0002-5636-735X mike_casazza@usgs.gov","orcid":"https://orcid.org/0000-0002-5636-735X","contributorId":2091,"corporation":false,"usgs":true,"family":"Casazza","given":"Michael","email":"mike_casazza@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":464741,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Pyke, D.A.","contributorId":62713,"corporation":false,"usgs":true,"family":"Pyke","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":464743,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The U.S. Environmental Protection Agency has established aquatic life criteria for some of these constituents, and it is therefore possible to evaluate their risk to aquatic life. However, of the major ions associated with produced waters, chloride is the only one with an established aquatic life criterion (U.S. Environmental Protection Agency, 1988). \r\n\r\nThe focus of this research was NaHCO<sub>3</sub>, a compound that is a major constituent of coalbed natural gas produced waters in the Tongue and Powder River Basins. This project included laboratory experiments, field in situ experiments, a field mixing zone study, and a fishery presence/absence assessment. \r\n\r\nThough this investigation focuses on the Tongue and Powder River Basins, the information is applicable to other watersheds where sodium bicarbonate is a principle component of product water either from CBNG or from traditional or unconventional oil and gas development. These data can also be used to separate effects of saline discharges from those potentially posed by other constituents. Finally, this research effort and the additional collaboration with USGS Water Resources and Mapping, Bureau of Land Management, US Environmental Protection Agency, State of Montana, State of Wyoming, Montana State University, University of Wyoming, and others as part of a Powder River Aquatic Task Group, can be used as a model for successful approaches to studying landscapes with energy development. \r\n\r\nThe laboratory acute toxicity experiments were completed with a suite of organisms, including 7 species of fish, 5 species of invertebrates, and 1 amphibian species. Experiments performed on these multiple species resulted in LC50s that ranged from 1,120 to greater than (>) 8,000 milligrams sodium bicarbonate per liter (mg NaHCO<sub>3</sub>/L) (also defined as 769 to >8,000 milligrams bicarbonate per liter (mg HCO<sub>3</sub>-/L) or total alkalinity expressed as 608 to >4,181 milligrams calcium carbonate per liter (mg CaCO<sub>3</sub>/L)) that varied across species and lifestage within a species. The age at which fish were exposed to NaHCO<sub>3</sub> significantly affected the severity of toxic responses for some organisms. The chronic toxicity of NaHCO<sub>3</sub> was defined in experiments that lasted from 7&mdash;60 days post-hatch. For these experiments, sublethal effects such as growth and reproduction, in addition to significant reductions in survival were included in the final determination of effects. Chronic toxicity was observed at concentrations that ranged from 450 to 800mg NaHCO<sub>3</sub>/L (also defined as 430 to 657 mg HCO<sub>3</sub>-/L or total alkalinity expressed as 354 to 539 mg CaCO<sub>3</sub>/L) and the specific concentration depended on the sensitivity of the four species of invertebrates and fish exposed. Sublethal investigations during chronic studies revealed percent decrease in the activity of sodium-potassium adenosine triphosphatase (Na/K ATPase, an enzyme involved in ionoregulation) and the age of the fish at the onset of the decrease may affect the ability of fathead minnow to survive exposures to NaHCO<sub>3</sub>. A database of toxicity evaluations of NaHCO<sub>3</sub> on aquatic life has been constructed. Using these data, sample acute and chronic criteria of 459 and 381 mg NaHCO<sub>3</sub>/L, respectively, can be calculated for the protection of aquatic life. The final derivation and implementation of such criteria is, of course, left to the discretion of the concerned management agencies. \r\n\r\nA combination of in situ experiments, static-renewal experiments performed simultaneously with in situ experiments, and static renewal experiments performed with site water in the laboratory, demonstrated that untreated coalbed natural gas (CBNG) product water from the Tongue and Powder River Basins reduces survival of fathead minnow and pallid sturgeon. More precisely, the survival of early-lifestage fathead minnow, especially those less than 6-days post hatch (dph), likely is reduced significantly in the field when concentrations of NaHCO<sub>3</sub> rise above 1,500 mg/L. However, age was not a factor for pallid sturgeon and they were sensitive to product water regardless of age. \r\n\r\nTreatment with the Higgins Loop&trade; technology and dilution of untreated water increased survival in the laboratory. Both of these situations reduced ammonia in addition to the concentrations of NaHCO<sub>3</sub>. These experiments addressed the acute toxicity of effluent waters being added to the main stem rivers, but did not address issues related to the volumes of water that may be added to the watershed. Mixing zones of the three outfalls studied ranged from approximately 800&mdash;1,200 m below the confluence and the areas within these mixing zones with acutely lethal concentrations of NaHCO<sub>3</sub> (as defined by the presence of concentrated dye) are limited. The areas with concentrations of NaHCO<sub>3</sub> more than the concentrations likely to cause significant mortality, and more than the calculated sample water-quality criteria in the Tongue and Powder River Basins appear to be limited to tributaries and parts of mixing zones with considerable additions of untreated effluent.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20125008","collaboration":"Prepared in cooperation with Montana Fish, Wildlife, and Parks, U.S. Bureau of Land Management, and the U.S. Environmental Protection Agency","usgsCitation":"Farag, A.M., and Harper, D., 2012, The potential effects of sodium bicarbonate, a major constituent from coalbed natural gas production, on aquatic life: U.S. Geological Survey Scientific Investigations Report 2012-5008, vi, 101 p., https://doi.org/10.3133/sir20125008.","productDescription":"vi, 101 p.","onlineOnly":"Y","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":257587,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2012_5008.JPG"},{"id":334534,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2012/5008/sir12-5008.pdf","size":"2.18 MB","linkFileType":{"id":1,"text":"pdf"}},{"id":257583,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2012/5008/","linkFileType":{"id":5,"text":"html"}}],"projection":"Lambert Conformal Conic","datum":"North American Datum 1983","country":"United States","state":"Montana;Wyoming","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -107.5,42.5 ], [ -107.5,46.75 ], [ -104.5,46.75 ], [ -104.5,42.5 ], [ -107.5,42.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baeabe4b08c986b32426c","contributors":{"authors":[{"text":"Farag, Aida M. 0000-0003-4247-6763 aida_farag@usgs.gov","orcid":"https://orcid.org/0000-0003-4247-6763","contributorId":1139,"corporation":false,"usgs":true,"family":"Farag","given":"Aida","email":"aida_farag@usgs.gov","middleInitial":"M.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":464760,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harper, David D.","contributorId":102946,"corporation":false,"usgs":true,"family":"Harper","given":"David D.","affiliations":[],"preferred":false,"id":464761,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This fatal prion disease has led to declines in populations which have high CWD prevalence and areas with both high and low infection rates have experienced economic losses in wildlife recreation and fears of potential spill-over into livestock or humans. Research from human and veterinary medicine has established that the prion protein gene (</span><i>Prnp</i><span>) encodes the protein responsible for transmissible spongiform encephalopathies (TSEs). Polymorphisms in the<span>&nbsp;</span></span><i>Prnp</i><span><span>&nbsp;</span>gene can lead to different prion forms that moderate individual susceptibility to and progression of TSE infection.<span>&nbsp;</span></span><i>Prnp</i><span><span>&nbsp;</span>genes have been sequenced in a number of cervid species including those currently infected by CWD (elk, mule deer, white-tailed deer, moose) and those for which susceptibility is not yet determined (caribou, fallow deer, sika deer). Over thousands of sequences examined, the<span>&nbsp;</span></span><i>Prnp</i><span><span>&nbsp;</span>gene is remarkably conserved within the family Cervidae; only 16 amino acid polymorphisms have been reported within the 256 amino acid open reading frame in the third exon of the<span>&nbsp;</span></span><i>Prnp</i><span><span>&nbsp;</span>gene. Some of these polymorphisms have been associated with lower rates of CWD infection and slower progression of clinical CWD. Here we review the body of research on<span>&nbsp;</span></span><i>Prnp</i><span><span>&nbsp;</span>genetics of North American cervids. Specifically, we focus on known polymorphisms in the<span>&nbsp;</span></span><i>Prnp</i><span><span>&nbsp;</span>gene, observed genotypic differences in CWD infection rates and clinical progression, mechanisms for genetic TSE resistance related to both the cervid host and the prion agent and potential for natural selection for CWD-resistance.

Lake sediment is a likely sink for many hydrophobic synthetic organic compounds (SOCs); however, partitioning between the sediment and the overlying water could result in the sediment acting as a secondary contaminant source. Locating the chemical plumes may be important to understanding possible chemical stressors to aquatic organisms. Passive sampling devices (SPMDs and POCIS) were suspended in LVB at depths of 3.0, 4.7, and 6.7 (lake bottom) meters in June of 2008 to determine the vertical distribution of SOCs in the water column. A custom sediment probe was used to also bury the samplers in the sediment at depths of 0&ndash;10, 10&ndash;20, and 20&ndash;30 cm. The greatest number of detections in samplers buried in the sediment was at the 0&ndash;10 cm depth. Concentrations of many hydrophobic SOCs were twice as high at the sediment&ndash;water interface than in the mid and upper water column. Many SOCs related to wastewater effluents, including fragrances, insect repellants, sun block agents, and phosphate flame retardants, were found at highest concentrations in the middle and upper water column. There was evidence to suggest that the water infiltrated into the sediment had a different chemical composition than the rest of the water column and could be a potential risk exposure to bottom-dwelling aquatic organisms.","largerWorkType":{"id":2,"text":"Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.chemosphere.2012.03.040","usgsCitation":"Alvarez, D., Rosen, M.R., Perkins, S.D., Cranor, W.L., Schroeder, V., and Jones-Lepp, T.L., 2012, Bottom sediment as a source of organic contaminants in Lake Mead, Nevada, USA: Chemosphere, v. 88, no. 5, p. 605-611, https://doi.org/10.1016/j.chemosphere.2012.03.040.","productDescription":"7 p.","startPage":"605","endPage":"611","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":257602,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257593,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chemosphere.2012.03.040","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Nevada","otherGeospatial":"Lake Mead","volume":"88","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f22ae4b0c8380cd4b043","contributors":{"authors":[{"text":"Alvarez, David A.","contributorId":72755,"corporation":false,"usgs":true,"family":"Alvarez","given":"David A.","affiliations":[],"preferred":false,"id":464506,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rosen, Michael R. 0000-0003-3991-0522 mrosen@usgs.gov","orcid":"https://orcid.org/0000-0003-3991-0522","contributorId":495,"corporation":false,"usgs":true,"family":"Rosen","given":"Michael","email":"mrosen@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":464502,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Perkins, Stephanie D. sperkins@usgs.gov","contributorId":2745,"corporation":false,"usgs":true,"family":"Perkins","given":"Stephanie","email":"sperkins@usgs.gov","middleInitial":"D.","affiliations":[],"preferred":true,"id":464503,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cranor, Walter L.","contributorId":21653,"corporation":false,"usgs":true,"family":"Cranor","given":"Walter","email":"","middleInitial":"L.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":464505,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schroeder, Vickie L.","contributorId":8574,"corporation":false,"usgs":true,"family":"Schroeder","given":"Vickie L.","affiliations":[],"preferred":false,"id":464504,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jones-Lepp, Tammy L.","contributorId":103132,"corporation":false,"usgs":true,"family":"Jones-Lepp","given":"Tammy","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":464507,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}
