These new data support a rotational opening model for southern Canada Basin. There is a central basement ridge possibly representing an extinct spreading center with oceanic crustal velocities and blocky basement morphology characteristic of spreading centre crust surrounding this ridge. Basement elevation is lower in the south, mostly due to sediment loading subsidence. The sedimentary succession is thickest in the southern Beaufort Sea region, reaching more than 15 km, and generally thins to the north and west. In the north, grabens and half-grabens are indicative of extension. Alpha-Mendeleev Ridge is a large igneous province in northern Amerasia Basin, presumably emplaced synchronously with basin formation. It overprints most of northern Canada Basin structure. The seafloor and sedimentary succession of Canada Basin is remarkably flat-lying in its central region, with little bathymetric change over most of its extent. Reflections that correlate over 100s of kms comprise most of the succession and on-lap bathymetric and basement highs. They are interpreted as representing deposits from unconfined turbidity current flows. Sediment distribution patterns reflect changing source directions during the basin&rsquo;s history. Initially, probably late Cretaceous to Paleocene synrift sediments sourced from the Alaska and Mackenzie-Beaufort margins. This unit shows a progressive series of onlap unconformities with a younging trend towards Alpha and Northwind ridges, likely a response to contemporaneous subsidence. Sediment source direction appeared to shift to the Canadian Arctic Archipelago margin for the Eocene and Oligocene, likely due to uplift of Arctic islands during the Eurekan Orogeny. The final stage of sedimentation appears to be from the Mackenzie-Beaufort region for the Miocene and Pliocene when drainage patterns shifted in the Yukon and Alaska to the Mackenzie valley. Upturned reflections at onlap positions may indicate syn-depositional subsidence. There is little evidence, at least at a regional seismic data scale, of contemporaneous or post-depositional sediment reworking, suggesting little large-scale geostrophic or thermohaline-driven bottom current activity.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Arctic Technology Conference: Challenges for today, opportunities for tomorrow","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Arctic Technology Conference 2012","conferenceDate":"December 3-5, 2012","conferenceLocation":"Houston, Texas, United States","language":"English","publisher":"Offshore Technology Conference","doi":"10.4043/23797-MS","usgsCitation":"Mosher, D.C., Shimeld, J., Hutchinson, D.R., Chian, D., Lebedeva-Ivanova, N., and Jackson, R., 2012, Canada Basin revealed, <i>in</i> Arctic Technology Conference: Challenges for today, opportunities for tomorrow, Houston, Texas, United States, December 3-5, 2012, 11 p., https://doi.org/10.4043/23797-MS.","productDescription":"11 p.","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-041987","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":307166,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Arctic Ocean, Canada Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.21990729069734,\n              70.77962290516786\n            ],\n            [\n              -132.07655009391658,\n              71.11604815059647\n            ],\n            [\n              -127.743467599712,\n              72.07575620369948\n            ],\n            [\n              -126.47019082691355,\n              73.8675469961417\n            ],\n            [\n              -124.63968021783072,\n              76.15296901893535\n            ],\n            [\n              -121.20483912106104,\n              78.69417054187653\n            ],\n            [\n              -127.49898152161086,\n              81.20862939238191\n            ],\n            [\n              -144.49225629388687,\n              82.86708520508876\n            ],\n            [\n              -173.1770377934791,\n              81.31295045587689\n            ],\n            [\n              -175.35815779559644,\n              77.52761471467934\n            ],\n            [\n              -168.7036592133713,\n              74.51299612473647\n            ],\n            [\n              -162.0116361944457,\n              73.22203342559573\n            ],\n            [\n              -149.21990729069734,\n              70.77962290516786\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationDate":"2012-12-03","publicationStatus":"PW","scienceBaseUri":"55d84bb1e4b0518e3546efe6","contributors":{"authors":[{"text":"Mosher, David C.","contributorId":66118,"corporation":false,"usgs":false,"family":"Mosher","given":"David","email":"","middleInitial":"C.","affiliations":[{"id":18105,"text":"University of New Hampshire, Durham","active":true,"usgs":false}],"preferred":false,"id":569225,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shimeld, John","contributorId":146869,"corporation":false,"usgs":false,"family":"Shimeld","given":"John","affiliations":[],"preferred":false,"id":569226,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hutchinson, Deborah R. 0000-0002-2544-5466 dhutchinson@usgs.gov","orcid":"https://orcid.org/0000-0002-2544-5466","contributorId":521,"corporation":false,"usgs":true,"family":"Hutchinson","given":"Deborah","email":"dhutchinson@usgs.gov","middleInitial":"R.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":569227,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Chian, D","contributorId":118639,"corporation":false,"usgs":true,"family":"Chian","given":"D","affiliations":[],"preferred":false,"id":569228,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lebedeva-Ivanova, Nina","contributorId":146870,"corporation":false,"usgs":false,"family":"Lebedeva-Ivanova","given":"Nina","email":"","affiliations":[],"preferred":false,"id":569229,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jackson, Ruth","contributorId":36799,"corporation":false,"usgs":true,"family":"Jackson","given":"Ruth","email":"","affiliations":[],"preferred":false,"id":569230,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Dry deposition estimates were obtained by combining monitored two- to four-hourly speciated ambient concentrations with modeled hourly dry deposition velocities (V<sub>d</sub>) calculated using forecasted meteorology. Annual dry deposition of GOM+PBM was estimated to be in the range of 0.4 to 8.1 μg m<sup>−2</sup> at these locations with GOM deposition being mostly five to ten times higher than PBM deposition, due to their different modeled V<sub>d</sub> values. Net annual GEM dry deposition was estimated to be in the range of 5 to 26 μg m<sup>−2</sup> at 18 sites and 33 μg m<sup>−2</sup> at one site. The estimated dry deposition agrees very well with limited surrogate-surface dry deposition measurements of GOM and PBM, and also agrees with litterfall mercury measurements conducted at multiple locations in eastern and central North America. This study suggests that GEM contributes much more than GOM+PBM to the total dry deposition at the majority of the sites considered here; the only exception is at locations close to significant point sources where GEM and GOM+PBM contribute equally to the total dry deposition. The relative magnitude of the speciated dry deposition and their good comparisons with litterfall deposition suggest that mercury in litterfall originates primarily from GEM, which is consistent with the limited number of previous field studies. The study also supports previous analyses suggesting that total dry deposition of mercury is equal to, if not more important than, wet deposition of mercury on a regional scale in eastern North America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Atmospheric Chemistry and Physics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"European Geosciences Union (Copernicus Publications)","publisherLocation":"Munich, Germany","doi":"10.5194/acp-12-4327-2012","usgsCitation":"Zhang, L., Blanchard, P., Gay, D., Prestbo, E., Risch, M., Johnson, D., Narayan, J., Zsolway, R., Holsen, T., Miller, E., Castro, M., Graydon, J., , L., and Dalziel, J., 2012, Estimation of speciated and total mercury dry deposition at monitoring locations in eastern and central North America: Atmospheric Chemistry and Physics, v. 12, no. 9, p. 4327-4340, https://doi.org/10.5194/acp-12-4327-2012.","productDescription":"14 p.","startPage":"4327","endPage":"4340","ipdsId":"IP-033882","costCenters":[{"id":346,"text":"Indiana Water Science Center","active":true,"usgs":true}],"links":[{"id":489181,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/acp-12-4327-2012","text":"Publisher Index Page"},{"id":263594,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5194/acp-12-4327-2012"},{"id":263596,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States;Canada","otherGeospatial":"Piney Reservoir;Beltsville;Grand Bay Nerr;Thompson Farm;Brigantine;New Brunswick;Chester;Elizabeth Lab;Kejimkujik National Park;Bronx;Huntington Wildlife;Rochester;Rochester B;Athens Super Site;Stilwell;Antelope Island;Salt Lake City;Underhill;Canaan Valley Institute;Experimental Lakes Area","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.46,29.45 ], [ -114.46,50.51 ], [ -61.68,50.51 ], [ -61.68,29.45 ], [ -114.46,29.45 ] ] ] } } ] }","volume":"12","issue":"9","noUsgsAuthors":false,"publicationDate":"2012-05-15","publicationStatus":"PW","scienceBaseUri":"50bd12dce4b069d93eefc4b2","contributors":{"authors":[{"text":"Zhang, L.","contributorId":41543,"corporation":false,"usgs":true,"family":"Zhang","given":"L.","email":"","affiliations":[],"preferred":false,"id":469495,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blanchard, P.","contributorId":70267,"corporation":false,"usgs":true,"family":"Blanchard","given":"P.","affiliations":[],"preferred":false,"id":469500,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gay, D.A.","contributorId":54018,"corporation":false,"usgs":true,"family":"Gay","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":469496,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Prestbo, E.M.","contributorId":83739,"corporation":false,"usgs":true,"family":"Prestbo","given":"E.M.","affiliations":[],"preferred":false,"id":469502,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Risch, M.R.","contributorId":55032,"corporation":false,"usgs":true,"family":"Risch","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":469497,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Johnson, D.","contributorId":85955,"corporation":false,"usgs":true,"family":"Johnson","given":"D.","email":"","affiliations":[],"preferred":false,"id":469503,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Narayan, J.","contributorId":41309,"corporation":false,"usgs":true,"family":"Narayan","given":"J.","email":"","affiliations":[],"preferred":false,"id":469494,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Zsolway, R.","contributorId":32059,"corporation":false,"usgs":true,"family":"Zsolway","given":"R.","email":"","affiliations":[],"preferred":false,"id":469492,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Holsen, T.M.","contributorId":33122,"corporation":false,"usgs":true,"family":"Holsen","given":"T.M.","affiliations":[],"preferred":false,"id":469493,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Miller, E.

Our goal was to compare use of these field types by birds to guide habitat conservation in the region. During 19 August-6 December 2005, we counted a total of 80,316 birds during 23 surveys of 5 FLD (4 wheat, 1 alfalfa) fields and 8,225 birds during 38 surveys of 33 IRG (23 cotton, 4 tomato, 3 wheat, 1 alfalfa, 1 oat, 1 fallow) fields. We recorded 14 waterfowl (13 duck, 1 goose), 29 other waterbird (coots, shorebirds, grebes, pelicans, herons, egrets, gulls, terns), and 14 non-waterbird (passerines, raptors, and vultures) species on FLD fields compared to 5 duck, 14 other waterbird, and 9 non-waterbird species on IRG fields. Species composition differed by field type; waterfowl (FLD vs. IRG, 16.2% vs. 1.3%) and other waterbirds (80.4% vs. 71.6%) comprised a greater percentage and non-waterbirds (3.5% vs. 27.1%) a lower percentage of birds on FLD than on IRG fields. The modeled density estimate of waterfowl was 108 times greater on FLD than IRG fields and 7.4 times greater on grain than non-grain fields. The density estimate of other waterbirds was 11.8 times greater on FLD than IRG fields and 4.4 times greater on grain than non-grain fields. The density estimate of non-waterbirds was 14.3 times greater on grain than non-grain fields but did not differ by flood type. Long duration (i.e., >1 week) flooding increased waterbird use of grain fields in the Tulare Basin more than in the northern Central Valley. Thus, even though water costs are high in the Tulare Basin, if net benefit to waterbirds is considered, management programs that increase availability of FLD-type fields (especially grain) in the Tulare Basin may be a cost-effective option to help meet waterbird habitat conservation goals in the Central Valley of California.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Fish and Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish and Wildlife Service","publisherLocation":"Arlington, VA","doi":"10.3996/092011-JFWM-056","usgsCitation":"Fleskes, J.P., Skalos, D.A., and Farinha, M.A., 2012, Bird use of fields treated postharvest with two types of flooding in Tulare Basin, California: Journal of Fish and Wildlife Management, v. 3, no. 1, p. 164-174, https://doi.org/10.3996/092011-JFWM-056.","productDescription":"11 p.; Supplemental Material","startPage":"164","endPage":"174","ipdsId":"IP-032377","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":474226,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3996/092011-jfwm-056","text":"Publisher Index Page"},{"id":263635,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263634,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3996/092011-JFWM-056"}],"country":"United States","state":"California","otherGeospatial":"Central Valley;Tulare;Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.1851,34.8421 ], [ -121.1851,36.9861 ], [ -118.5257,36.9861 ], [ -118.5257,34.8421 ], [ -121.1851,34.8421 ] ] ] } } ] }","volume":"3","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50bdc9eae4b0f6301734766f","contributors":{"authors":[{"text":"Fleskes, Joseph P. 0000-0001-5388-6675 joe_fleskes@usgs.gov","orcid":"https://orcid.org/0000-0001-5388-6675","contributorId":1889,"corporation":false,"usgs":true,"family":"Fleskes","given":"Joseph","email":"joe_fleskes@usgs.gov","middleInitial":"P.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":469513,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Skalos, Daniel A.","contributorId":64123,"corporation":false,"usgs":true,"family":"Skalos","given":"Daniel","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":469515,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Farinha, Melissa A.","contributorId":7791,"corporation":false,"usgs":true,"family":"Farinha","given":"Melissa","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":469514,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The study was part of the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazard Susceptibility project, a regional project funded by the Coastal and Marine Geology Program to understand how natural forcings and anthropogenic modifications influence coastal ecosystems and their susceptibility to coastal hazards. Mobile Bay is a large drowned-river estuary that has been modified significantly by humans to accommodate the Port of Mobile. Examples include repeated dredging of a large shipping channel down the central axis of the bay and construction of a causeway across the head of the bay and at the foot of the bayhead delta. In addition to modifications, the bay is also known to have episodic periods of low oxygen (hypoxia) that result in significant mortality to fish and benthic organisms (May, 1973). For this study a series of surface sediment samples were collected. Surface benthic foraminiferal and bulk geochemical data provide the modern baseline conditions of the bay and can be used as a reference to changing environmental parameters in the past (Osterman and Smith, in press) and into the future.

We used eight microsatellite markers to investigate genetic structure and levels of genetic diversity in a relict population of wood frogs (<i>Lithobates sylvatica</i>) in Rocky Mountain National Park, Colorado, where recent disturbances have altered hydrologic processes and fragmented amphibian habitat. We also estimated migration rates among subpopulations, tested for a pattern of isolation-by-distance, and looked for evidence of a recent population bottleneck. The results from the clustering algorithm in Program STRUCTURE indicated the population is partitioned into two genetic clusters (subpopulations), and this result was further supported by factorial component analysis. In addition, an estimate of FST (FST = 0.0675, P value \\0.0001) supported the genetic differentiation of the two clusters. Estimates of migration rates among the two subpopulations were low, as were estimates of genetic variability. Conservation of the population of wood frogs may be improved by increasing the spatial distribution of the population and improving gene flow between the subpopulations. Construction or restoration of wetlands in the landscape between the clusters has the potential to address each of these objectives.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Conservation Genetics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer Netherlands","doi":"10.1007/s10592-012-0395-1","usgsCitation":"Scherer, R., Muths, E., Noon, B., and Oyler-McCance, S., 2012, The genetic structure of a relict population of wood frogs: Conservation Genetics, v. 13, no. 6, p. 1521-1530, https://doi.org/10.1007/s10592-012-0395-1.","productDescription":"10 p.","startPage":"1521","endPage":"1530","numberOfPages":"10","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":291049,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291048,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10592-012-0395-1"}],"country":"United States","state":"Colorado","otherGeospatial":"Rocky Mountain National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -105.913714,40.158067 ], [ -105.913714,40.553787 ], [ -105.493583,40.553787 ], [ -105.493583,40.158067 ], [ -105.913714,40.158067 ] ] ] } } ] }","volume":"13","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-08-18","publicationStatus":"PW","scienceBaseUri":"5412b9c0e4b0239f1986bb1b","contributors":{"authors":[{"text":"Scherer, Rick","contributorId":67427,"corporation":false,"usgs":true,"family":"Scherer","given":"Rick","affiliations":[],"preferred":false,"id":496395,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Muths, Erin 0000-0002-5498-3132","orcid":"https://orcid.org/0000-0002-5498-3132","contributorId":14012,"corporation":false,"usgs":true,"family":"Muths","given":"Erin","affiliations":[],"preferred":false,"id":496393,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Noon, Barry","contributorId":64934,"corporation":false,"usgs":true,"family":"Noon","given":"Barry","affiliations":[],"preferred":false,"id":496394,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Oyler-McCance, Sara","contributorId":96820,"corporation":false,"usgs":true,"family":"Oyler-McCance","given":"Sara","affiliations":[],"preferred":false,"id":496396,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

S. Geological Survey, in cooperation with the U.S. Department of Energy, is mapping the distribution of basalt flows and sedimentary interbeds at the Idaho National Laboratory in three dimensions to provide data for refining numerical models of groundwater flow and contaminant transport in the eastern Snake River Plain aquifer. Paleomagnetic inclination and polarity data from basalt samples from 47 coreholes are being used to create a three-dimensional (3-D) model of the subsurface of the southern part of the INL. Surface and sub-surface basalt flows can be identified in individual cores and traced in three dimensions on the surface and in the subsurface for distances of more than 20 km using a combination of paleomagnetic, stratigraphic, and <sup>40</sup>Ar/<sup>39</sup>Ar data. Eastern Snake River Plain olivine tholeiite basalts have K<sub>2</sub>O contents of 0.2 to 1.0 weight per cent. In spite of the low-K content, high-precision <sup>40</sup>Ar/<sup>39</sup>Ar ages were obtained by applying a protocol that employs short irradiation times (minimizing interferences from Ca derived <sup>36</sup>Ar), frequent measurement of various size atmospheric Ar pipettes to monitor and correct for temporal variation, and signal size dependent nonlinearity in spectrometer mass bias, resulting in age dates with resolution generally between 2 to 10% of the age. 3-D models of subsurface basalt flows are being used to: (1) Estimate eruption volumes; (2) locate the approximate vent areas and extent of sub-surface flows; and (3) Help locate high and low transmissivity zones. Results indicate that large basalt eruptions (&gt;3 km<sup>3</sup>) occurred at and near the Central Facilities Area between 637 ka and 360 ka; at and near the Radioactive Waste Management Complex before 540 ka; and north of the Naval Reactors Facility at about 580 ka. Since about 360 ka, large basalt flows have erupted along the Arco-Big Southern Butte Volcanic Rift Zone and the Axial Volcanic Zone, and flowed northerly towards the Central Facilities Area.

Roads and utility corridors have been shown to harbor more alien species than the surrounding vegetation and are therefore believed to contribute to alien plant persistence and spread. Recreational trails represent another corridor that could harbor alien species and aid their spread. Effective management of invasive species requires understanding how alien plants are distributed at trailheads and trails and how their dispersal may be influenced by native vegetation. Our overall goal was to investigate the distribution of alien plants at trailheads and trails in the Rocky Mountains of Colorado. At trailheads, we found that although the number of alien species was less than the number of native species, alien plant cover ( x̄=50%) did not differ from native plant cover, and we observed a large number of alien seedlings in the soil seed bank, suggesting that alien plants are a large component of trailhead communities and will continue to be so in the future. Along trails, we found higher alien species richness and cover on trail (as opposed to 4 m from the trail) in 3 out of 4 vegetation types, and we observed higher alien richness and cover in meadows than in other vegetation types. Plant communities at both trailheads and trails, as well as seed banks at trailheads, contain substantial diversity and abundance of alien plants. These results suggest that recreational trails in the Rocky Mountains of Colorado may function as corridors that facilitate the spread of alien species into wildlands. Our results suggest that control of alien plants should begin at trailheads where there are large numbers of aliens and that control efforts on trails should be prioritized by vegetation type.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Western North American Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"BioOne","doi":"10.3398/064.072.0408","usgsCitation":"Wells, F.H., Lauenroth, W.K., and Bradford, J.B., 2012, Recreational trails as corridors for alien plants in the Rocky Mountains, USA: Western North American Naturalist, v. 72, no. 4, p. 507-533, https://doi.org/10.3398/064.072.0408.","productDescription":"27 p.","startPage":"507","endPage":"533","ipdsId":"IP-033860","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":488134,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://scholarsarchive.byu.edu/wnan/vol72/iss4/8","text":"External Repository"},{"id":274787,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274692,"type":{"id":15,"text":"Index Page"},"url":"https://ojs.lib.byu.edu/wnan/index.php/wnan/article/view/3887"},{"id":274786,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3398/064.072.0408"}],"country":"United States","state":"Colorado","otherGeospatial":"Rocky Mountains","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.0603,36.9924 ], [ -109.0603,41.0034 ], [ -102.0409,41.0034 ], [ -102.0409,36.9924 ], [ -109.0603,36.9924 ] ] ] } } ] }","volume":"72","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51dd30efe4b0f72b44719cbf","contributors":{"authors":[{"text":"Wells, Floye H.","contributorId":103953,"corporation":false,"usgs":true,"family":"Wells","given":"Floye","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":480272,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lauenroth, William K.","contributorId":80982,"corporation":false,"usgs":false,"family":"Lauenroth","given":"William","email":"","middleInitial":"K.","affiliations":[{"id":7098,"text":"University of Wyoming, Department of Botany, 1000 E.

The model predicts that pressure and ground deformation are characterized by an exponential function of time, consistent with our observations. The geyser's conduit is connected to a reservoir at a depth of at least 42 m, and pressure changes in the reservoir can produce the observed ground deformations through either a poroelastic or elastic mechanical model.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/2012GL054012","usgsCitation":"Rudolph, M., Manga, M., Hurwitz, S., Johnston, M.J., Karlstrom, L., and Wang, C., 2012, Mechanics of Old Faithful Geyser, Calistoga, CA: Geophysical Research Letters, v. 39, no. 24, 5 p., https://doi.org/10.1029/2012GL054012.","productDescription":"5 p.","numberOfPages":"5","ipdsId":"IP-042117","costCenters":[{"id":148,"text":"Branch of Regional Research-Western Region","active":false,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":474228,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2012gl054012","text":"Publisher Index Page"},{"id":275312,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275308,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2012GL054012"}],"country":"United States","state":"California","city":"Calistoga","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.602437,38.596588 ], [ -122.602437,38.597143 ], [ -122.601875,38.597143 ], [ -122.601875,38.596588 ], [ -122.602437,38.596588 ] ] ] } } ] }","volume":"39","issue":"24","noUsgsAuthors":false,"publicationDate":"2012-12-21","publicationStatus":"PW","scienceBaseUri":"51efa5f2e4b0b09fbe58f19d","contributors":{"authors":[{"text":"Rudolph, M.L.","contributorId":93365,"corporation":false,"usgs":true,"family":"Rudolph","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":468869,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Manga, M.","contributorId":39261,"corporation":false,"usgs":true,"family":"Manga","given":"M.","affiliations":[],"preferred":false,"id":468867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hurwitz, Shaul 0000-0001-5142-6886 shaulh@usgs.gov","orcid":"https://orcid.org/0000-0001-5142-6886","contributorId":2169,"corporation":false,"usgs":true,"family":"Hurwitz","given":"Shaul","email":"shaulh@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":468866,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnston, Malcolm J.

In the coastal ocean, the amount of data is also growing dramatically due to new sensor and modeling technologies. Lagging behind this deluge of ocean data, however, is an effective framework of standards, protocols, tools and culture needed to transform the way we generate knowledge and value from ocean data. The Data Management and Communications (DMAC) sub-system was envisioned to provide such an information management capability for IOOS®, promoting standards and policies to be implemented by data providers across the IOOS enterprise. DMAC needs to build upon the successes and lessons learned during development of web service standards and promote a set of end-to-end standards and procedures for the entire ocean-data life cycle, including documentation through metadata, quality control and quality assurance, effective data discovery, and stewardship through archiving. Because information technology is constantly changing, a multiyear, top-down design and implementation plan is not workable. DMAC should start by promoting a set of protocols that are functional for specific use cases, creating a modular framework in which modules can be replaced as technologies change. In addition to promoting protocols, DMAC needs to support training, flexible online documentation, support, and social networking that enable users to share code, techniques and experiences. Through this bottom-up approach, trust and understanding will foster adoption by the community. Finally, a compliance and certification process should be developed that allows IOOS to ensure that they meet the needs of customers and other stakeholders while complying with regulatory requirements related to the data. If this approach is followed, we will enable breakthroughs in ocean data–driven technology similar to those common elsewhere in our society, fulfilling the broader mission of IOOS.","conferenceTitle":"U.S. Integrated Ocean Observing System (IOOS) Summit","conferenceDate":"2012-11-13T00:00:00","conferenceLocation":"Herdon, VA","language":"English","publisher":"Interagency

Walruses are benthic foragers and may shift their spatial patterns of foraging in response to \nchanges in prey distribution. We used data from satellite radio-tags attached to walruses in 2009-2010 to \nmap walrus foraging locations with concurrent sampling of benthic infauna to examine relationships \nbetween distributions of dominant walrus prey and spatial patterns of walrus foraging. Walrus foraging \nwas concentrated offshore in the NE Chukchi Sea, and coastal areas of northwestern Alaska when sea ice \nwas sparse.

Coulomb failure models based on a frictional strength threshold offer one explanation for instances of rapid‐onset triggered seismicity that develop during the surface‐wave peak dynamic stressing. Evaluation of the triggering potential of surface‐wave dynamic stresses acting on critically stressed faults using a Mohr’s circle representation together with the Coulomb failure criteria indicates that Love waves should have a higher triggering potential than Rayleigh waves for most fault orientations and wave incidence angles. That (1) the onset of triggered seismicity often appears to begin during the Rayleigh wave rather than the earlier arriving Love wave, and (2) Love‐wave amplitudes typically exceed those for Rayleigh waves suggests that the explanation for rapid‐onset dynamic triggering may not reside solely with a simple static‐threshold friction mode. The results also indicate that normal faults should be more susceptible to dynamic triggering by 20‐s Rayleigh‐wave stresses than thrust faults in the shallow seismogenic crust (<10  km) while the advantage tips in favor of reverse faults greater depths. This transition depth scales with wavelength and coincides roughly with the transition from retrograde‐to‐prograde particle motion. Locally elevated pore pressures may have a role in the observed prevalence of dynamic triggering in extensional regimes and geothermal/volcanic systems. The result is consistent with the apparent elevated susceptibility of extensional or transtensional tectonic regimes to remote triggering by Rayleigh‐wave dynamic stresses than compressional or transpressional regimes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Bulletin of the Seismological Society of America","publisherLocation":"Stanford, CA","doi":"10.1785/0120120085","usgsCitation":"Hill, D.P., 2012, Dynamic stresses, coulomb failure, and remote triggering: corrected: Bulletin of the Seismological Society of America, v. 102, no. 6, p. 2313-2336, https://doi.org/10.1785/0120120085.","productDescription":"24 p.","startPage":"2313","endPage":"2336","numberOfPages":"24","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":291154,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291153,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120120085"}],"volume":"102","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-12-01","publicationStatus":"PW","scienceBaseUri":"57f7f428e4b0bc0bec0a0df5","contributors":{"authors":[{"text":"Hill, David P. hill@usgs.gov","contributorId":2600,"corporation":false,"usgs":true,"family":"Hill","given":"David","email":"hill@usgs.gov","middleInitial":"P.","affiliations":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":496713,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The relative potential for Love- and Rayleigh-wave dynamic stresses to trigger tectonic tremor through failure on critically stressed thrust and vertical strike-slip faults under the Coulomb-Griffith failure criteria as a function of incidence angle are anticorrelated over the 15- to 30-km-depth range that hosts tectonic tremor. Love-wave potential is high for strike-parallel incidence on low-angle reverse faults and null for strike-normal incidence; the opposite holds for Rayleigh waves. Love-wave potential is high for both strike-parallel and strike-normal incidence on vertical, strike-slip faults and minimal for ~45° incidence angles. The opposite holds for Rayleigh waves. This pattern is consistent with documented instances of tremor triggered by Love waves incident on the Cascadia megathrust and the San Andreas fault (SAF) in central California resulting from shear failure on weak faults (apparent friction is μ* ≤ 0:2). Documented instances of tremor triggered by surface waves with strike-parallel incidence along the Nankai megathrust beneath Shikoku, Japan, however, are associated primarily with Rayleigh waves. This is consistent with the tremor bursts resulting from mixed-mode failure (crack opening and shear failure) facilitated by near-lithostatic ambient pore pressure, low differential stress, with a moderate friction coefficient (μ ~ 0:6) on the Nankai subduction interface. Rayleigh-wave dilatational stress is relatively weak at tectonic tremor source depths and seems unlikely to contribute significantly to the triggering process, except perhaps for an indirect role on the SAF in sustaining tremor into the Rayleigh-wave coda that was initially triggered by Love waves.","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":"Stanford, CA","doi":"10.1785/0120120086","usgsCitation":"Hill, D.P., 2012, Surface-wave potential for triggering tectonic (nonvolcanic) tremor-corrected: Bulletin of the Seismological Society of America, v. 102, no. 6, p. 2337-2355, https://doi.org/10.1785/0120120086.","productDescription":"19 p.","startPage":"2337","endPage":"2355","numberOfPages":"19","costCenters":[],"links":[{"id":291152,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291151,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120120086"}],"volume":"102","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-12-01","publicationStatus":"PW","scienceBaseUri":"57f7f428e4b0bc0bec0a0df7","contributors":{"authors":[{"text":"Hill, David P. hill@usgs.gov","contributorId":2600,"corporation":false,"usgs":true,"family":"Hill","given":"David","email":"hill@usgs.gov","middleInitial":"P.","affiliations":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":496712,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

These modifications have been implicated in the decline in habitat diversity and native fishes. However, dike structures have been modified in the Missouri River USA to increase habitat diversity to aid in the recovery of native fishes. We compared species occupancy and fish community composition at natural sandbars and at notched and un-notched rock dikes along the lower Missouri River to determine if notching dikes increases species diversity or occupancy of native fishes. Fish were collected using gill nets, trammel nets, otter trawls, and mini fyke nets throughout the lower 1212 river km of the Missouri River USA from 2003 to 2006. Few differences in species richness and diversity were evident among engineered dike structures and natural sandbars. Notching a dike structure had no effect on proportional abundance of fluvial dependents, fluvial specialists, and macrohabitat generalists. Occupancy at notched dikes increased for two species but did not differ for 17 other species (81%). Our results suggest that dike structures may provide suitable habitats for fluvial species compared with channel sand bars, but dike notching did not increase abundance or occupancy of most Missouri River fishes.

Current knowledge of the biodegradability of DOM in these rivers is limited, particularly for large rivers discharging to the Arctic Ocean. We conducted a seasonally comprehensive study of biodegradable dissolved organic carbon (BDOC) dynamics in the Yukon River and two of its tributaries in Alaska, USA. Distinct seasonal patterns of BDOC, consistent across a wide range of watershed size, indicate BDOC is transported year-round. Relative biodegradability (%BDOC) was greatest during winter, and decreased into spring and summer. Due to large seasonal differences in DOC concentration, the greatest concentrations of BDOC (mg C L</span><span>&minus;1</span><span>) occurred during spring freshet, followed by winter and summer. While chemical composition of DOM was an important driver of BDOC, the overriding control of BDOC was mineral nutrient availability due to wide shifts in carbon (C) and nitrogen (N) stoichiometry across seasons. We calculated seasonal and annual loads of BDOC exported by the Yukon River by applying measured BDOC concentrations to daily water discharge values, and also by applying an empirical correlation between %BDOC and the ratio of DOC to dissolved inorganic N (DIN) to total DOC loads.

Up to 425 individual fish were collected, comprising 42 fish species, from the sand flats bordering the lagoon of the atoll. Quantitative parasitological examinations of each fish were performed. Morphological descriptions of the encountered digenean metacercariae are provided, together with their prevalence, mean intensities, host and tissue-use. Up to 33,964 individuals were recovered representing 19 digenean metacercaria species from eight families. The species composition of digeneans in lagoon fishes at Palmyra Atoll is a subset of what has previously been reported for the EIP. Further, the large diversity and abundance of metacercariae reported in this study highlight the utility of including this group in future ecological research in the EIP marine ecoregion.","language":"English","publisher":"Cambridge University Press","doi":"10.1017/S0022149X11000526","usgsCitation":"Vidal-Martínez, V., Aguirre-Macedo, M.L., McLaughlin, J., Hechinger, R.F., Jaramillo, A., Shaw, J., James, A., Kuris, A.M., and Lafferty, K.D., 2012, Digenean metacercariae of fishes from the lagoon flats of Palmyra Atoll, Eastern Indo-Pacific: Journal of Helminthology, v. 86, no. 4, p. 493-509, https://doi.org/10.1017/S0022149X11000526.","productDescription":"17 p.","startPage":"493","endPage":"509","numberOfPages":"17","ipdsId":"IP-026428","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":294122,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294051,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1017/S0022149X11000526"}],"otherGeospatial":"Indo-pacific;Palmyra Atoll","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -162.12906,5.865629 ], [ -162.12906,5.900051 ], [ -162.034676,5.900051 ], [ -162.034676,5.865629 ], [ -162.12906,5.865629 ] ] ] } } ] }","volume":"86","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-01-05","publicationStatus":"PW","scienceBaseUri":"541bf423e4b0e96537ddf68a","contributors":{"authors":[{"text":"Vidal-Martínez, V.

The initial focus of such legislation in both countries centered on preserving natural and culturally significant areas for posterity. Although this objective remains primary, philosophies and practices have changed. A Canadian vision for ungulate management emerged during the latter half of the 20th century to protect and maintain or restore the ecological integrity of representative samples of the country’s 39 distinct landscapes, and to include provisions for traditional hunting and fishing practices representative of past cultural impacts on the environment. The current ungulate management approach in the U.S. relies on natural (ecological) processes, as long as normal conditions are promoted and there is no impairment of natural resources. Emphasizing natural processes as the basis has been a challenge because ecosystem dynamics are complex and management is multi-jurisdictional. Additionally, natural regulation typically will not prevent ungulates from reaching and sustaining densities that are incompatible with preservation or restoration of native flora and fauna, natural processes, or historical landscapes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"The Wildlife Society Technical Review","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Wildlife Society","usgsCitation":"Demarais, S., Cornicelli, L., Kahn, R., Merrill, E., Miller, C., Peek, J., Porter, W., and Sargeant, G., 2012, Ungulate management in national parks of the United States and Canada: The Wildlife Society Technical Review, v. 12-05, 68 p.","productDescription":"68 p.","ipdsId":"IP-040600","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":277547,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277545,"type":{"id":11,"text":"Document"},"url":"https://wildlife.org/documents/technical-reviews/docs/ungulate-management.pdf"}],"country":"Canada;United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -173.0,16.91 ], [ -173.0,83.1 ], [ -52.6,83.1 ], [ -52.6,16.91 ], [ -173.0,16.91 ] ] ] } } ] }","volume":"12-05","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"523433f3e4b0b9e9b3336dda","contributors":{"authors":[{"text":"Demarais, S.","contributorId":55328,"corporation":false,"usgs":true,"family":"Demarais","given":"S.","affiliations":[],"preferred":false,"id":483861,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cornicelli, L.","contributorId":62851,"corporation":false,"usgs":true,"family":"Cornicelli","given":"L.","email":"","affiliations":[],"preferred":false,"id":483862,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kahn, R.","contributorId":29729,"corporation":false,"usgs":true,"family":"Kahn","given":"R.","email":"","affiliations":[],"preferred":false,"id":483857,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Merrill, E.","contributorId":11106,"corporation":false,"usgs":true,"family":"Merrill","given":"E.","email":"","affiliations":[],"preferred":false,"id":483856,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Miller, C.","contributorId":44114,"corporation":false,"usgs":false,"family":"Miller","given":"C.","affiliations":[],"preferred":false,"id":483859,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peek, J.M.","contributorId":34889,"corporation":false,"usgs":true,"family":"Peek","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":483858,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Porter, W.F.","contributorId":81597,"corporation":false,"usgs":true,"family":"Porter","given":"W.F.","email":"","affiliations":[],"preferred":false,"id":483863,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Sargeant, G.A.","contributorId":51681,"corporation":false,"usgs":true,"family":"Sargeant","given":"G.A.","email":"","affiliations":[],"preferred":false,"id":483860,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

In this study we applied a large-scale ecosystem model that included dynamics of organic soil horizons and soil organic matter characteristics of multiple pools to assess forest C stock changes of the Yukon River Basin (YRB) in Alaska, USA, and Canada from 1960 through 2006, a period characterized by substantial climate warming and increases in wildfire. The model was calibrated for major forests with data from long-term research sites and evaluated using a forest inventory database. The regional assessment indicates that forest vegetation C storage increased by 46 Tg C, but that total soil C storage did not change appreciably during this period. However, further analysis suggests that C has been continuously lost from the mineral soil horizon since warming began in the 1970s, but has increased in the amorphous organic soil horizon. Based on a factorial experiment, soil C stocks would have increased by 158 Tg C if the YRB had not undergone warming and changes in fire regime. The analysis also identified that warming and changes in fire regime were approximately equivalent in their effects on soil C storage, and interactions between these two suggests that the loss of organic horizon thickness associated with increases in wildfire made deeper soil C stocks more vulnerable to loss via decomposition. Subbasin analyses indicate that C stock changes were primarily sensitive to the fraction of burned forest area within each subbasin and that boreal forest ecosystems in the YRB are currently transitioning from being sinks to sources at ∼0.7% annual area burned. We conclude that it is important for international mitigation efforts focused on controlling atmospheric CO<sub>2</sub> to consider how climate warming and changes in fire regime may concurrently affect the CO<sub>2</sub> sink strength of boreal forests. It is also important for large-scale biogeochemical and earth system models to include organic soil dynamics in applications to assess regional C dynamics of boreal forests responding to warming and changes in fire regime.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Tempe, AZ","doi":"10.1890/11-1957.1","usgsCitation":"Yuan, F., Yi, S., McGuire, A., Johnson, K., Liang, J., Harden, J., Kasischke, E., and Kurz, W., 2012, Assessment of boreal forest historical C dynamics in the Yukon River Basin: relative roles of warming and fire regime change: Ecological Applications, v. 22, no. 8, p. 2091-2109, https://doi.org/10.1890/11-1957.1.","productDescription":"19 p.","startPage":"2091","endPage":"2109","numberOfPages":"19","costCenters":[],"links":[{"id":291115,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291114,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/11-1957.1"}],"volume":"22","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f428e4b0bc0bec0a0dfb","contributors":{"authors":[{"text":"Yuan, F.M.","contributorId":64165,"corporation":false,"usgs":true,"family":"Yuan","given":"F.M.","email":"","affiliations":[],"preferred":false,"id":496625,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yi, S.H.","contributorId":38481,"corporation":false,"usgs":true,"family":"Yi","given":"S.H.","email":"","affiliations":[],"preferred":false,"id":496622,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McGuire, A.

Melt inclusions (MI) hosted in pyroxene and plagioclase crystals from eight dacitic–rhyodacitic eruptive deposits (71–7.7 ka) were analyzed to determine variations in volatile-element concentrations and changes in magma storage conditions leading up to and including the climactic eruption of Crater Lake caldera. Temperatures (Fe–Ti oxides) increased through the series of dacites, then decreased, and increased again through the rhyodacites (918–968 to ~950 to 845–895 °C). Oxygen fugacity began at nickel–nickel-oxide buffer (NNO) +0.8 (71 ka), dropped slightly to NNO +0.3, and then climbed to its highest value with the climactic eruption (7.7 ka) at NNO +1.1 log units. In parallel with oxidation state, maximum MI sulfur concentrations were high early in the eruptive sequence (~500 ppm), decreased (to ~200 ppm), and then increased again with the climactic eruption (~500 ppm). Maximum MI sulfur correlates with the Sr content (as a proxy for LREE, Ba, Rb, P<sub>2</sub>O<sub>5</sub>) of recharge magmas, represented by basaltic andesitic to andesitic enclaves and similar-aged lavas. These results suggest that oxidized Sr-rich recharge magmas dominated early and late in the development of the pre-climactic dacite–rhyodacite system. Dissolved H<sub>2</sub>O concentrations in MI do not, however, correlate with these changes in dominant recharge magma, instead recording vapor solubility relations in the developing shallow magma storage and conduit region. Dissolved H<sub>2</sub>O concentrations form two populations through time: the first at 3–4.6 wt% (with a few extreme values up to 6.1 wt%) and the second at ≤2.4 wt%. CO<sub>2</sub> concentrations measured in a subset of these inclusions reach up to 240 ppm in early-erupted deposits (71 ka) and are below detection in climactic deposits (7.7 ka). Combined H<sub>2</sub>O and CO<sub>2</sub> concentrations and solubility models indicate a dominant storage region at 4–7 km (up to 12 km), with drier inclusions that diffusively re-equilibrated and/or were trapped at shallower depths. Boron and Cl (except in the climactic deposit) largely remained in the melt, suggesting vapor–melt partition coefficients and gas fractions were low. Modeled Li, F, and S vapor–melt partition coefficients are higher than those of B and Cl. The decrease in maximum MI CO<sub>2</sub> concentration following the earliest dacitic eruptions is interpreted to result from a broadening of the shallow storage region to greater than the diameter of subjacent feeders, so that greater proportions of reservoir magma were to the side of CO<sub>2</sub>-bearing vapor bubbles ascending vertically from the locus of recharge magma injection, thereby escaping recarbonation by streaming vapor bubbles. The Mazama melt inclusions provide a picture of a growing magma storage region, where chemical variations in melt and magma occur due to changes in the nature and supply rate of magma recharge, the timing of degassing, and the possible degree of equilibration with gases from below.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s00410-012-0787-8","usgsCitation":"Wright, H.M., Bacon, C.R., Vazquez, J.A., and Sisson, T.W., 2012, Sixty thousand years of magmatic volatile history before the caldera-forming eruption of Mount Mazama, Crater Lake, Oregon: Contributions to Mineralogy and Petrology, v. 164, no. 6, p. 1027-1052, https://doi.org/10.1007/s00410-012-0787-8.","productDescription":"26 p.","startPage":"1027","endPage":"1052","numberOfPages":"26","ipdsId":"IP-037119","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":280359,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280346,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00410-012-0787-8"}],"country":"United States","state":"Oregon","otherGeospatial":"Crater Lake;Mount Mazama","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -130.0,40.0 ], [ -130.0,50.0 ], [ -120.0,50.0 ], [ -120.0,40.0 ], [ -130.0,40.0 ] ] ] } } ] }","volume":"164","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-08-22","publicationStatus":"PW","scienceBaseUri":"53cd7306e4b0b29085108ae9","contributors":{"authors":[{"text":"Wright, Heather M. 0000-0001-9013-507X hwright@usgs.gov","orcid":"https://orcid.org/0000-0001-9013-507X","contributorId":3949,"corporation":false,"usgs":true,"family":"Wright","given":"Heather","email":"hwright@usgs.gov","middleInitial":"M.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":487425,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bacon, Charles R. 0000-0002-2165-5618 cbacon@usgs.gov","orcid":"https://orcid.org/0000-0002-2165-5618","contributorId":2909,"corporation":false,"usgs":true,"family":"Bacon","given":"Charles","email":"cbacon@usgs.gov","middleInitial":"R.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":487424,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vazquez, Jorge A. 0000-0003-2754-0456 jvazquez@usgs.gov","orcid":"https://orcid.org/0000-0003-2754-0456","contributorId":4458,"corporation":false,"usgs":true,"family":"Vazquez","given":"Jorge","email":"jvazquez@usgs.gov","middleInitial":"A.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":501,"text":"Office of Science Quality and Integrity","active":true,"usgs":true},{"id":5056,"text":"Office of the AD Energy and Minerals, and Environmental Health","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"preferred":true,"id":487426,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sisson, Thomas W. 0000-0003-3380-6425 tsisson@usgs.gov","orcid":"https://orcid.org/0000-0003-3380-6425","contributorId":2341,"corporation":false,"usgs":true,"family":"Sisson","given":"Thomas","email":"tsisson@usgs.gov","middleInitial":"W.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":487423,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This species has been introduced since at least 1979 in southern Florida, USA, where it likely began reproducing and became established during the 1980s (Meshaka et al. 2000, Snowet al. 2007b,Kraus 2009, Krysko et al. 2011, Willson et al. 2011). Python bivittatus has been documented in Florida consuming a variety of mammals and birds, and the American Alligator(Alligator mississippiensis) (Snowet al. 2007a, 2007b; Harvey et al. 2008; Rochford et al. 2010b; Holbrook and Chesnes 2011), many of which are protected species.
