Four of these viruses are clearly associated with clinical disease: alcelaphine herpesvirus 1 (AlHV-1) carried by wildebeest (Connochaetes spp.); ovine herpesvirus 2 (OvHV-2), ubiquitous in domestic sheep; caprine herpesvirus 2 (CpHV-2), endemic in domestic goats; and the virus of unknown origin found causing classic MCF in white-tailed deer (Odocoileus virginianus; MCFV-WTD). Using serology and polymerase chain reaction with degenerate primers targeting a portion of the herpesviral DNA polymerase gene, evidence of three previously unrecognized rhadinoviruses in the MCF virus group was found in muskox (Ovibos moschatus), Nubian ibex (Capra nubiana), and gemsbok (South African oryx, Oryx gazella), respectively. Based on sequence alignment, the viral sequence in the muskox is most closely related to MCFV-WTD (81.5% sequence identity) and that in the Nubian ibex is closest to CpHV-2 (89.3% identity). The viral sequence in the gemsbok is most closely related to AlHV-1 (85.1% identity). No evidence of disease association with these viruses has been found. ??

Holocene migration into central and northern Wyoming and southern Montana from the south proceeded by a series of long-distance dispersal events, which were paced by climate variability and structured by the geographic distribution and connectivity of suitable habitats on the landscape. The migration of Utah juniper into the region involved multiple long-distance dispersal events, ranging from 30 to 135 km. One of the earliest established populations, on East Pryor Mountain in south central Montana, is currently the northernmost population of the species. Establishment by long-distance dispersal of that population and another in the Bighorn Basin occurred during a period of relatively dry climate between 7500 and 5400 years ago. Further expansion of these initial colonizing populations and backfilling to occupy suitable sites to the south was delayed during a wet period from 5400 to 2800 years ago. Development of dry conditions 2800 years ago led to a rapid expansion in which Utah juniper colonized sites throughout its current range. Landscape structure and climate variability play important roles in governing the pattern and pace of natural invasions and deserve close attention in studying and modeling plant invasions, whether exotic or natural.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Monographs","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00129615","usgsCitation":"Lyford, M., Jackson, S., Betancourt, J., and Gray, S., 2003, Influence of landscape structure and climate variability on a late holocene plant migration: Ecological Monographs, v. 73, no. 4, p. 567-583.","startPage":"567","endPage":"583","numberOfPages":"17","costCenters":[],"links":[{"id":233147,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"73","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b49e4b0c8380cd623c9","contributors":{"authors":[{"text":"Lyford, M.E.","contributorId":33883,"corporation":false,"usgs":true,"family":"Lyford","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":403037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jackson, S.T.","contributorId":90072,"corporation":false,"usgs":true,"family":"Jackson","given":"S.T.","email":"","affiliations":[],"preferred":false,"id":403039,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Betancourt, J.L. 0000-0002-7165-0743","orcid":"https://orcid.org/0000-0002-7165-0743","contributorId":87505,"corporation":false,"usgs":true,"family":"Betancourt","given":"J.L.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":403038,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gray, S.T.","contributorId":19680,"corporation":false,"usgs":true,"family":"Gray","given":"S.T.","email":"","affiliations":[],"preferred":false,"id":403036,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

It is an uncommon mafic end member of&nbsp;</span>low<span>-</span>sulfidation<span>&nbsp;Au-Ag deposits associated with tholeiitic bimodal basalt-rhyolite magmatism. The ore is hosted by a basalt-andesite eruptive center that formed between about 16.4 to 15.8 Ma during early mafic eruptions related to regionally extensive bimodal magmatism. Hydrothermal alteration and Au-Ag ores formed at about 15.6 Ma and were tightly controlled by&nbsp;</span>north<span>-northwest- to&nbsp;</span>north<span>-striking high-angle fault and breccia zones developed during rifting, emplacement of mafic dikes, and eruption of mafic lava flows. Hydrothermal alteration assemblages are zoned outward from fluid conduits in the sequence silica-adularia, adularia-smectite, smectite (intermediate argillic), and smectite-carbonate (propylitic). All alteration types contain abundant pyrite and/or marcasite ± arsenopyrite. Field relations indicate that silica-adularia alteration is superimposed on argillic and propylitic alteration. Little or no steam-heated acid-sulfate alteration is present, probably the result of a near-surface water table during hydrothermal alteration and ore deposition. Two distinct ore types are present at&nbsp;</span>Mule<span>&nbsp;</span>Canyon<span>: early replacement and later open-space filling. Replacement ores consist of disseminated and vesicle-filling pyrite, marcasite, and arsenopyrite in argillically altered or weakly silicified rocks. Ore minerals consist of Au-bearing arsenopyrite and arsenian pyrite overgrowths on earlier-formed pyrite and marcasite. Open-space filling ores include narrow stockwork quartz-adularia veins, banded and crustiform opaline and chalcedonic silica-adularia veins, silica-adularia cemented breccias, and sparse carbonate-pyrite and/or marcasite veins. Ore minerals consist mostly of electrum and Ag sulfide and selenide minerals, with minor to major amounts of pyrite, marcasite, and arsenopyrite, and local stibnite. Both types of ores have similar geochemical signatures, characterized by high Au, Ag, As, Sb, and Se contents, locally high Hg, Mo, Tl, and W contents, and&nbsp;</span>low<span>&nbsp;Cu, Pb, and Zn contents. Stable isotope data indicate that ore fluids consisted dominantly of meteoric water that evolved by deep circulation through Paleozoic sedimentary rocks at&nbsp;</span>low<span>&nbsp;water/rock ratios (about 1) and high temperatures (&gt;200°C). Calculated isotopic compositions of ore fluids are δ&nbsp;</span><sup>18</sup><span>O&nbsp;</span><sub>H2O</sub><span>&nbsp;= -3 to -7 per mil, δD&nbsp;</span><sub>H2O</sub><span>&nbsp;= -107 to -124 per mil, δ&nbsp;</span><sup>13</sup><span>C&nbsp;</span><sub>CO2</sub><span>&nbsp;= 0 to -6 per mil, and δ&nbsp;</span><sup>34</sup><span>S&nbsp;</span><sub>H2S</sub><span>&nbsp;= -3 to +8 per mil. The ore fluids obtained much of their H&nbsp;</span><sub>2</sub><span>S and CO&nbsp;</span><sub>2</sub><span>&nbsp;and probably scavenged ore metals and trace elements from the Paleozoic sedimentary rocks. Some H&nbsp;</span><sub>2</sub><span>S and CO&nbsp;</span><sub>2</sub><span>&nbsp;may have been derived from degassing Miocene magmas.&nbsp;</span>Mule<span>&nbsp;</span>Canyon<span>&nbsp;formed at shallow depths, probably about 100 m below the paleosurface. Ore fluids were dilute, nearly neutral in pH, reduced, H&nbsp;</span><sub>2</sub><span>S-rich, and CO&nbsp;</span><sub>2</sub><span>-bearing. Peak temperatures in ore zones reached 230° to 265°C at nearly lithostatic pressures when some crystalline quartz ± adularia precipitated, but most ore formed at temperatures &lt;200°C at near hydrostatic pressures and was accompanied by precipitation of opaline and chalcedonic silica ± adularia ± calcite and dolomite. Deposition of&nbsp;</span>gold<span>&nbsp;in As-rich overgrowths on pyrite and/or marcasite in disseminated ores occurred owing to decreasing H&nbsp;</span><sub>2</sub><span>S in the ore fluids resulting from&nbsp;</span>sulfidation<span>&nbsp;reactions. Later electrum and Ag selenide precipitation in open spaces occurred owing to boiling, loss of H&nbsp;</span><sub>2</sub><span>S to the vapor phase, and cooling.&nbsp;</span>Mule<span>&nbsp;</span>Canyon<span>&nbsp;is similar to most other&nbsp;</span>low<span>-</span>sulfidation<span>&nbsp;Au-Ag deposits associated with Miocene tholeiitic bimodal basalt-rhyolite magmatism in the Great Basin, such as Sleeper, Midas, and Buckhorn. Major differences at&nbsp;</span>Mule<span>&nbsp;</span>Canyon<span>&nbsp;are the high Fe sulfide contents of some ores and altered wall rocks, the paucity of silicification, and the presence of only narrow and discontinuous&nbsp;</span>gold<span>-bearing siliceous veins. These differences primarily are due to the mafic composition of the host rocks.&nbsp;</span>Mule<span>&nbsp;</span>Canyon<span>&nbsp;differs from&nbsp;</span>low<span>-</span>sulfidation<span>&nbsp;deposits associated with subduction-related calc-alkaline porphyry intrusions, such as the Comstock lode, in that a much smaller proportion of water, salts, and metals was derived from crystallizing magmas.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.98.2.425","issn":"03610128","usgsCitation":"John, D., Hofstra, A., Fleck, R., Brummer, J., and Saderholm, E., 2003, Geologic setting and genesis of the Mule Canyon low-sulfidation epithermal gold-silver deposit, north-central Nevada: Economic Geology, v. 98, no. 2, p. 425-463, https://doi.org/10.2113/gsecongeo.98.2.425.","productDescription":"39 p.","startPage":"425","endPage":"463","costCenters":[],"links":[{"id":387482,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United  States","state":"Nevada","otherGeospatial":"north-central Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -118.43261718749999,\n              39.87601941962116\n            ],\n            [\n              -115.31249999999999,\n              39.87601941962116\n            ],\n            [\n              -115.31249999999999,\n              42.13082130188811\n            ],\n            [\n              -118.43261718749999,\n              42.13082130188811\n            ],\n            [\n              -118.43261718749999,\n              39.87601941962116\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"98","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a21d1e4b0c8380cd56afb","contributors":{"authors":[{"text":"John, D.

Stable isotopes revealed similarity of diet at one colony where conventional sampling was not possible. We confirmed that sea ice importantly affects diet composition of this species in neritic waters, and found that (1) quality of summer diet cannot explain different population growth rates among colonies, and (2) stable isotope analysis of chick tissues (toenails) is a useful tool to synoptically describe diet in this species over a large area.</span></p>","language":"English","publisher":"Oxford","doi":"10.1650/0010-5422(2003)105[95:SATVOD]2.0.CO;2","issn":"00105422","usgsCitation":"Ainley, D., Ballard, G., Barton, K.J., Karl, B.J., Rau, G., Ribic, C., and Wilson, P.R., 2003, Spatial and temporal variation of diet within a presumed metapopulation of Adelie penguins: Condor, v. 105, no. 1, p. 95-106, https://doi.org/10.1650/0010-5422(2003)105[95:SATVOD]2.0.CO;2.","productDescription":"12 p.","startPage":"95","endPage":"106","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":478472,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1650/0010-5422(2003)105[95:satvod]2.0.co;2","text":"Publisher Index Page"},{"id":387465,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"105","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9458e4b08c986b31aa0e","contributors":{"authors":[{"text":"Ainley, D.

For both the Gaussian and bi-Gaussian distributions, and in the spherical three-space of intensity, inclination, and declination, we obtain analytical expressions for the marginal density functions, the cumulative distributions, and the expected values and variances for each spherical coordinate (including the angle with respect to the axis of symmetry of the distributions). The mathematical expressions for the intensity and off-axis angle are closed-form and especially manageable, with the intensity distribution being Rayleigh-Rician. In the limit of small relative vectorial dispersion, the Gaussian (bi-Gaussian) directional distribution approaches a Fisher (Bingham) distribution and the intensity distribution approaches a normal distribution. In the opposite limit of large relative vectorial dispersion, the directional distributions approach a spherically-uniform distribution and the intensity distribution approaches a Maxwell distribution. We quantify biases in estimating the properties of the vector field resulting from the use of simple arithmetic averages, such as estimates of the intensity or the inclination of the mean vector, or the variances of these quantities. With the statistical framework developed here and using the maximum-likelihood method, which gives unbiased estimates in the limit of large data numbers, we demonstrate how to formulate the inverse problem, and how to estimate the mean and variance of the magnetic vector field, even when the data consist of mixed combinations of directions and intensities. We examine palaeomagnetic secular-variation data from Hawaii and Re??union, and although these two sites are on almost opposite latitudes, we find significant differences in the mean vector and differences in the local vectorial variances, with the Hawaiian data being particularly anisotropic. These observations are inconsistent with a description of the mean field as being a simple geocentric axial dipole and with secular variation being statistically symmetrical with respect to reflection through the equatorial plane. Finally, our analysis of palaeomagnetic acquisition data from the 1960 Kilauea flow in Hawaii and the Holocene Xitle flow in Mexico, is consistent with the widely held suspicion that directional data are more accurate than intensity data.","language":"English","publisher":"Oxford Academic","doi":"10.1046/j.1365-246X.2003.01858.x","issn":"0956540X","usgsCitation":"Love, J.J., and Constable, C., 2003, Gaussian statistics for palaeomagnetic vectors: Geophysical Journal International, v. 152, no. 3, p. 515-565, https://doi.org/10.1046/j.1365-246X.2003.01858.x.","productDescription":"51 p.","startPage":"515","endPage":"565","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":208754,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1365-246X.2003.01858.x"},{"id":234723,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"152","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a14e6e4b0c8380cd54c05","contributors":{"authors":[{"text":"Love, Jeffrey J. 0000-0002-3324-0348 jlove@usgs.gov","orcid":"https://orcid.org/0000-0002-3324-0348","contributorId":760,"corporation":false,"usgs":true,"family":"Love","given":"Jeffrey","email":"jlove@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":407351,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Constable, C.G.","contributorId":22948,"corporation":false,"usgs":true,"family":"Constable","given":"C.G.","email":"","affiliations":[],"preferred":false,"id":407350,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In 1999 and 2000, the avicide DRC-1339 (3-chloro-4-methylaniline hydrochloride) was used experimentally on fall-ripening sunflower fields in North Dakota so researchers could evaluate its effectiveness for reducing crop depredations by blackbirds. DRC-1339 was applied to rice and broadcast on the ground in a confined area within ripening sunflower fields. One objective of this study was to determine whether nontarget birds, birds other than blackbirds, were eating rice and were exposed to the DRC-1339. In 1999, 8 of 11 (73%) sparrows collected by shotgun in sunflower fields treated with DRe-1339 had rice in their gastrointestinal (GI) tracts. In 2000, 5 mourning doves (<i>Zenaida macroura</i>) and 3 sparrows were collected by shotgun in sunflower fields treated with DRC-1339. Three doves had rice in their GI tracts, 4 doves and all 3 sparrows had measurable DRC1339 concentrations in their GI tracts, and 3 mourning doves and 1 savannah sparrow (<i>Passerculus sanduncbensis</i>) exhibited histopathological signs of kidney damage. In April 2002, untreated rice was applied to corn stubble plots in South Dakota to determine which bird species ate rice. In 2002, 3 of 3 song sparrows (<i>Melospiza melodia</i>) collected by shotgun had rice in their GI tracts. Our results demonstrate that the use of DRC-1339 to control blackbirds in the northern Great Plains will likely expose nontarget birds to the DRC-1339 bait.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Management of North American Blackbirds","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"National Wildlife Research Center","publisherLocation":"Fort Collins, CO","usgsCitation":"Custer, T.W., Custer, C.M., Dummer, P.M., Linz, G.M., Sileo, L., Stahl, R.S., and Johnston, J.J., 2003, Nontarget bird exposure to DRC-1339 during fall in North Dakota and spring in South Dakota, chap. <i>of</i> Management of North American Blackbirds, p. 64-70.","productDescription":"7 p.","startPage":"64","endPage":"70","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":127943,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":370664,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.aphis.usda.gov/wildlife_damage/nwrc/symposia/blackbirds_symposium/"}],"country":"United States","state":"North Dakota, South Dakota","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -104.1064453125,\n              43.03677585761058\n            ],\n            [\n              -96.94335937499999,\n              43.03677585761058\n            ],\n            [\n              -96.94335937499999,\n              49.03786794532644\n            ],\n            [\n              -104.1064453125,\n              49.03786794532644\n            ],\n            [\n              -104.1064453125,\n              43.03677585761058\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afde4b07f02db696e7f","contributors":{"editors":[{"text":"Linz, G.M.","contributorId":70877,"corporation":false,"usgs":true,"family":"Linz","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":504691,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Custer, Thomas W. 0000-0003-3170-6519 tcuster@usgs.gov","orcid":"https://orcid.org/0000-0003-3170-6519","contributorId":2835,"corporation":false,"usgs":true,"family":"Custer","given":"Thomas","email":"tcuster@usgs.gov","middleInitial":"W.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":296271,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Custer, Christine M. 0000-0003-0500-1582 ccuster@usgs.gov","orcid":"https://orcid.org/0000-0003-0500-1582","contributorId":1143,"corporation":false,"usgs":true,"family":"Custer","given":"Christine","email":"ccuster@usgs.gov","middleInitial":"M.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":296270,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dummer, Paul M. 0000-0002-2055-9480","orcid":"https://orcid.org/0000-0002-2055-9480","contributorId":90665,"corporation":false,"usgs":true,"family":"Dummer","given":"Paul","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":296275,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Linz, George M.","contributorId":32859,"corporation":false,"usgs":true,"family":"Linz","given":"George","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":296273,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sileo, Louis","contributorId":94623,"corporation":false,"usgs":true,"family":"Sileo","given":"Louis","email":"","affiliations":[],"preferred":false,"id":296276,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stahl, Randal S.","contributorId":27390,"corporation":false,"usgs":true,"family":"Stahl","given":"Randal","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":296272,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Johnston, John J.","contributorId":86289,"corporation":false,"usgs":true,"family":"Johnston","given":"John","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":296274,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

A total of seven nests was observed. We measured the following factors for daylight hours: percentage of time the female was on the nest (attendance), length of attendance bouts by the female, length of nest recesses, and adult provisioning rates. Comparisons were made between three stages of the 40-day nesting cycle: incubation (day 1-day 16), early nestling stage (day 17-day 30 [i.e., nestlings ??? 14 days old]), and late nestling stage (day 31-day 40 [i.e., nestlings > 14 days old]). Of seven nests observed, four fledged at least one nestling and three failed. One of these failed nests was filmed being depredated by a feral cat (Felis catus). Female nest attendance was near 82% during the incubation stage and decreased to 21% as nestlings aged. We did not detect a difference in attendance bout length between stages of the nesting cycle. Mean length of nest recesses increased from 4.5 min during the incubation stage to over 45 min during the late nestling stage. Mean number of nest recesses per hour ranged from 1.6 to 2.0. Food was delivered to nestlings by adults an average of 1.8 times per hour for the early nestling stage and 1.5 times per hour during the late nestling stage and did not change over time. Characterization of parental behavior by video had similarities to but also key differences from findings taken from blind observations. Results from this study will facilitate greater understanding of Palila reproductive strategies.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pacific Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00308870","usgsCitation":"Laut, M., Banko, P., and Gray, E., 2003, Nesting behavior of Palila, as assessed from video recordings: Pacific Science, v. 57, no. 4, p. 385-392.","startPage":"385","endPage":"392","numberOfPages":"8","costCenters":[],"links":[{"id":235867,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"57","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a64b1e4b0c8380cd72a2f","contributors":{"authors":[{"text":"Laut, M.E.","contributorId":53141,"corporation":false,"usgs":true,"family":"Laut","given":"M.E.","affiliations":[],"preferred":false,"id":405551,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Banko, P.C. 0000-0002-6035-9803","orcid":"https://orcid.org/0000-0002-6035-9803","contributorId":99531,"corporation":false,"usgs":true,"family":"Banko","given":"P.C.","affiliations":[],"preferred":false,"id":405553,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gray, E.M.","contributorId":62781,"corporation":false,"usgs":true,"family":"Gray","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":405552,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We sampled two mining-impacted and two relatively pristine streams in western Montana over a 12-month period, collecting samples every 4 weeks, with supplemental sampling (at least weekly) during spring runoff. We analyzed all samples for dissolved (operationally defined as <0.2 ??m) and total recoverable concentrations. Generally, the trace elements (Al, As, Cu, Fe, Mn, and Zn) did not correlate linearly with streamflow, while the major elements (e.g., Ca, K, and Mg) did. Suspended sediment, total recoverable metals, and H+ followed clockwise hysteresis rotations, driven by short-term flushing events during the very early stages of spring runoff. Mining-impacted sites had higher concentrations of many trace elements than did relatively pristine sites. One of the mining impacted sites exhibited strong geochemical responses to spring rain events in the basin. The results underscore the need to sample streams frequently during changing hydrologic and climatic conditions in order to accurately monitor surface water quality and to determine solute and particulate loads (both contaminant and noncontaminant).","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2001WR001247","usgsCitation":"Nagorski, S.A., Moore, J.N., McKinnon, T.E., and Smith, D., 2003, Geochemical response to variable streamflow conditions in contaminated and uncontaminated streams: Water Resources Research, v. 39, no. 2, p. 1-1-1-14, https://doi.org/10.1029/2001WR001247.","productDescription":"Article 1044; 14 p.","startPage":"1-1","endPage":"1-14","costCenters":[],"links":[{"id":234912,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":478418,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2001wr001247","text":"Publisher Index Page"}],"volume":"39","issue":"2","noUsgsAuthors":false,"publicationDate":"2003-02-28","publicationStatus":"PW","scienceBaseUri":"505a169ce4b0c8380cd551eb","contributors":{"authors":[{"text":"Nagorski, Sonia A.","contributorId":32940,"corporation":false,"usgs":true,"family":"Nagorski","given":"Sonia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":407213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, Johnnie N.","contributorId":13668,"corporation":false,"usgs":true,"family":"Moore","given":"Johnnie","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":407211,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McKinnon, Temple E.","contributorId":40238,"corporation":false,"usgs":false,"family":"McKinnon","given":"Temple","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":407212,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, David B. 0000-0001-8396-9105 dsmith@usgs.gov","orcid":"https://orcid.org/0000-0001-8396-9105","contributorId":1274,"corporation":false,"usgs":true,"family":"Smith","given":"David B.","email":"dsmith@usgs.gov","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":407210,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Long-term reproducibility of the method is between 2.5 and 5% with an advantage of rapid analysis on a single digestion of sediment sample and the potential of adding other elements of interest if so desired. Application of this method to two piston cores collected near the mouth of the Patuxent River in Chesapeake Bay showed that the accumulation of authigenic Mo and Cd varied in response to the changing bottom water redox conditions, with anoxia showing consistent oscillations throughout both pre-industrial and industrial times. Accumulation of authigenic U shows consistent oscillations as well, without any apparent increase in productivity related to anoxic trends. Degrees of Mo and Cd enrichment also inversely correlate to halophilic microfaunal assemblages already established as paleoclimate proxies within the bay indicating that bottom water anoxia is driven in part by the amount of freshwater discharge that the area receives. ?? 2002 Elsevier Science Ltd.
