A fragment of 410 bp of the non-coding region was analyzed for 12 individual manatees from Cuba and one from Florida, USA. Only two haplotypes were identified. Haplotype A1, found exclusively in Florida (including in the sample analyzed here) but also found in Mexico, the Dominican Republic and Puerto Rico, was the most frequent haplotype (11 of the 12 samples from Cuba) and widely distributed. The second haplotype A3, previously referred to as endemic from Belize, was identified from an individual stranded in Isabela de Sagua, north of Cuba. These preliminary results provide information about three major aspects of manatee biology: (1) the mtDNA genetic diversity of T. manatus in Cuba seems low as compared to other regions of the Caribbean; (2) the Cuban population likely belongs to the group comprising Florida and the portions of the Greater Antilles; and (3) the territories of Belize and Cuba have exchanged individuals at present or in a relatively recent past.</p>","language":"English","publisher":"Universidad de La Habana","collaboration":"University of Havana, Sea to Shore Alliance","usgsCitation":"Hernandez-Martinez, D., Alvarez-Aleman, A., Bonde, R.K., Powell, J., and Garcia-Machado, E., 2013, Diversidad haplotípica en el manatí Trichechus manatus en Cuba: resultados preliminares: Revista de investigación, v. 33, no. 2, p. 58-61.","productDescription":"7 p.","startPage":"58","endPage":"61","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-051908","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":299992,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"33","issue":"2","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5543522be4b0a658d79414a3","contributors":{"authors":[{"text":"Hernandez-Martinez, Damir","contributorId":139808,"corporation":false,"usgs":false,"family":"Hernandez-Martinez","given":"Damir","email":"","affiliations":[{"id":13279,"text":"Centro de Investigaciones Marinas, Universidad de La Habana","active":true,"usgs":false}],"preferred":false,"id":543066,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Alvarez-Aleman, Anmari","contributorId":21270,"corporation":false,"usgs":true,"family":"Alvarez-Aleman","given":"Anmari","affiliations":[],"preferred":false,"id":543067,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bonde, Robert K. 0000-0001-9179-4376 rbonde@usgs.gov","orcid":"https://orcid.org/0000-0001-9179-4376","contributorId":2675,"corporation":false,"usgs":true,"family":"Bonde","given":"Robert","email":"rbonde@usgs.gov","middleInitial":"K.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":543065,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Powell, James A.","contributorId":53514,"corporation":false,"usgs":true,"family":"Powell","given":"James A.","affiliations":[],"preferred":false,"id":543068,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Garcia-Machado, Erik","contributorId":139809,"corporation":false,"usgs":false,"family":"Garcia-Machado","given":"Erik","email":"","affiliations":[{"id":13279,"text":"Centro de Investigaciones Marinas, Universidad de La Habana","active":true,"usgs":false}],"preferred":false,"id":543069,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Macaque vCJD PrP</span><span>TSE</span><span>&nbsp;did not amplify using normal macaque brain homogenate as substrate (intraspecies PMCA). Next, we tested interspecies PMCA with normal brain homogenate of the southern red-backed vole (RBV), a close relative of the bank vole, seeded with macaque vCJD PrP</span><span>TSE</span><span>. The RBV has a natural polymorphism at residue 170 of the PrP-encoding gene (N/N, S/S, and S/N). We investigated the effect of this polymorphism on amplification of human and macaque vCJD PrP</span><span>TSE</span><span>.

This paper reviews the petroleum geochemistry, oil-oil, and oil-source correlations of the oil systems of the Williston Basin, providing a new perspective and some new findings. Petroleum systems with a known source (documented oil-source correlation) include the Red River (Ordovician), Winnipegosis (Devonian), Bakken (Devonian-Mississippian), Madison (Mississippian), and Tyler (Pennsylvanian) systems. Petroleum systems with an identified source rock but no documented oil-source correlation are considered hypothetical and include the Winnipeg (Ordovician), Duperow (Devonian), and Birdbear (Devonian). The Deadwood (Cambrian-Ordovician) petroleum system is speculative because a good oil-prone source rock has not been identified. The stratigraphic distribution of the oil families from each system is generally limited to the same formation from which they were sourced due to efficient seals and a paucity of vertical migration pathways, but some notable exceptions do occur.</p>\n<p class=\"indent\">Oil bulk properties such as API gravity, sulfur content, and pour point are much underutilized in the recent geochemical literature and are found to be useful here in differentiating oil families. The Red River petroleum system has two oil families that can be differentiated based on pour point. The oils in the Madison petroleum system can be divided into two families based on API gravity-sulfur content relationships, with one family derived from Type II-S kerogen and the other family derived from Type II kerogen with medium sulfur content. The Tyler petroleum system of the Williston Basin may be distinguished from the Heath-Tyler petroleum system in central Montana based on differences in geology and petroleum geochemistry, with Tyler petroleum system oils having a higher pour point and lower sulfur content.</p>","language":"English","publisher":"Rocky Mountain Association of Geologists","publisherLocation":"Denver, CO","usgsCitation":"Lillis, P.G., 2013, Review of oil families and their petroleum systems of the Williston Basin: Mountain Geologist, v. 50, no. 1, p. 5-31.","productDescription":"27 p.","startPage":"5","endPage":"31","numberOfPages":"27","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-036380","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":269649,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269648,"type":{"id":15,"text":"Index Page"},"url":"https://archives.datapages.com/data/mountain-geologist-rmag/data/050/050001/5_rmag-mg500005.htm"}],"country":"Canada, United States","otherGeospatial":"Williston Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -106.34765625,\n              45.19752230305685\n            ],\n            [\n              -106.34765625,\n              50.680797145321655\n            ],\n            [\n              -97.822265625,\n              50.680797145321655\n            ],\n            [\n              -97.822265625,\n              45.19752230305685\n            ],\n            [\n              -106.34765625,\n              45.19752230305685\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"50","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"514837a1e4b022dd171afedc","contributors":{"authors":[{"text":"Lillis, Paul G. 0000-0002-7508-1699 plillis@usgs.gov","orcid":"https://orcid.org/0000-0002-7508-1699","contributorId":1817,"corporation":false,"usgs":true,"family":"Lillis","given":"Paul","email":"plillis@usgs.gov","middleInitial":"G.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":472768,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

More recently, spatial interpolation techniques of point data have been shown to be effective for predicting streamflow statistics (i.e., flood flows and low-flow indices) in ungauged catchments. Literature reports successful applications of two techniques, canonical kriging, CK (or physiographical-space-based interpolation, PSBI), and topological kriging, TK (or top-kriging). CK performs the spatial interpolation of the streamflow statistic of interest in the two-dimensional space of catchment descriptors. TK predicts the streamflow statistic along river networks taking both the catchment area and nested nature of catchments into account. It is of interest to understand how these spatial interpolation methods compare with generalized least squares (GLS) regression, one of the most common approaches to estimate flood quantiles at ungauged locations. By means of a leave-one-out cross-validation procedure, the performance of CK and TK was compared to GLS regression equations developed for the prediction of 10, 50, 100 and 500 yr floods for 61 streamgauges in the southeast United States. TK substantially outperforms GLS and CK for the study area, particularly for large catchments. The performance of TK over GLS highlights an important distinction between the treatments of spatial correlation when using regression-based or spatial interpolation methods to estimate flood quantiles at ungauged locations. The analysis also shows that coupling TK with CK slightly improves the performance of TK; however, the improvement is marginal when compared to the improvement in performance over GLS.</span><span><br /></span></p>","language":"English","publisher":"Copernicus Publications","doi":"10.5194/hess-17-1575-2013","usgsCitation":"Archfield, S.A., Pugliese, A., Castellarin, A., Skoien, J.O., and Kiang, J.E., 2013, Topological and canonical kriging for design flood prediction in ungauged catchments: an improvement over a traditional regional regression approach?: Hydrology and Earth System Sciences, v. 17, p. 1575-1588, https://doi.org/10.5194/hess-17-1575-2013.","productDescription":"14 p.","startPage":"1575","endPage":"1588","numberOfPages":"14","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-041594","costCenters":[{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true}],"links":[{"id":474174,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/hess-17-1575-2013","text":"Publisher Index Page"},{"id":297289,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -171.73828125,\n              17.97873309555617\n            ],\n            [\n              -171.73828125,\n              71.35706654962706\n            ],\n            [\n              -66.26953125,\n              71.35706654962706\n            ],\n            [\n              -66.26953125,\n              17.97873309555617\n            ],\n            [\n              -171.73828125,\n              17.97873309555617\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"17","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2013-04-23","publicationStatus":"PW","scienceBaseUri":"54dd2c72e4b08de9379b3803","contributors":{"authors":[{"text":"Archfield, Stacey A. 0000-0002-9011-3871 sarch@usgs.gov","orcid":"https://orcid.org/0000-0002-9011-3871","contributorId":1874,"corporation":false,"usgs":true,"family":"Archfield","given":"Stacey","email":"sarch@usgs.gov","middleInitial":"A.","affiliations":[{"id":502,"text":"Office of Surface Water","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":538597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pugliese, Alessio","contributorId":138746,"corporation":false,"usgs":false,"family":"Pugliese","given":"Alessio","email":"","affiliations":[{"id":12516,"text":"Dept.

For example, in the false spring of 2012, an event embedded in long-term trends toward earlier spring [e.g., Schwartz et al., 2006], the frost damage to fruit trees totaled half a billion dollars in Michigan alone, prompting the federal government to declare the state a disaster area [Knudson, 2012].</p>","language":"English","publisher":"American Geophysical Union","doi":"10.1002/2013EO200001","usgsCitation":"Ault, T., Henebry, G., de Beurs, K., Schwartz, M., Betancourt, J.L., and Moore, D., 2013, The false spring of 2012, earliest in North American record: Eos, Transactions, American Geophysical Union, v. 94, no. 20, p. 181-183, https://doi.org/10.1002/2013EO200001.","productDescription":"3 p.","startPage":"181","endPage":"183","ipdsId":"IP-044739","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":490021,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2013eo200001","text":"Publisher Index Page"},{"id":338885,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"20","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2013-05-14","publicationStatus":"PW","scienceBaseUri":"58df6ac8e4b02ff32c6aea71","contributors":{"authors":[{"text":"Ault, T.R.","contributorId":14229,"corporation":false,"usgs":true,"family":"Ault","given":"T.R.","email":"","affiliations":[],"preferred":false,"id":687839,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Henebry, G.M.","contributorId":98055,"corporation":false,"usgs":true,"family":"Henebry","given":"G.M.","affiliations":[],"preferred":false,"id":687827,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"de Beurs, K.

This study examined differences in how burned and unburned plots on north versus south-facing slope aspects respond to rainfall. The largest wildfire impacts were litter/duff combustion on burned north-facing slopes versus soil-water retention reduction on burned south-facing slopes.</p><p>Wildfire is one of the most significant disturbances in mountainous landscapes, affecting water supply and ecologic function and setting the stage for natural hazards such as flash floods. The impacts of wildfire can affect the entire hydrologic cycle. Measurements of soil-water content and matric potential in the near surface (top 30 cm) captured the hydrologic state in both burned and unburned hillslopes during the first spring through fall period (1 June–1 Oct. 2011) after the 2010 Fourmile Canyon Fire near Boulder, CO. This time span included different hydrologic periods characterized by cyclonic frontal storms (low-intensity, long duration), convective storms (high-intensity, short duration), and dry periods. In mountainous environments, aspect can also control hydrologic states, so north- vs. south-facing slopes were compared. Wildfire tended to homogenize soil-water contents across aspects and with depth in the soil, yet it also may have introduced an aspect control on matric potential that was not observed in unburned soils. Post-wildfire changes in hydrologic state were observed in south-facing soils, probably reflecting decreased soil-water retention after wildfire. North-facing soils were impacted the most, in terms of hydrologic state, by the loss of water storage in the combusted litter–duff layer and forest canopy, which had provided a large “hydrologic buffering” capacity when unburned. Unsaturated zone measurements showed increased variability in hydrologic states and more rapid state transitions in wildfire-impacted soils. A simple, qualitative analysis suggested that the range of unsaturated-zone processes along the gravity–capillarity–adsorption continuum was expanded by wildfire for a given soil. The small number of experimental plots in this study suggests that further work is needed before these conclusions can be generalized to other geographic areas.</p>","language":"English","publisher":"Soil Science Society of America","doi":"10.2136/vzj2012.0089","usgsCitation":"Ebel, B.A., 2013, Wildfire and aspect effects on hydrologic states after the 2010 Fourmile Canyon Fire: Vadose Zone Journal, v. 12, no. 1, https://doi.org/10.2136/vzj2012.0089.","ipdsId":"IP-038010","costCenters":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":335829,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"1","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2013-02-04","publicationStatus":"PW","scienceBaseUri":"58ac0e31e4b0ce4410e7d60a","contributors":{"authors":[{"text":"Ebel, Brian A. 0000-0002-5413-3963 bebel@usgs.gov","orcid":"https://orcid.org/0000-0002-5413-3963","contributorId":2557,"corporation":false,"usgs":true,"family":"Ebel","given":"Brian","email":"bebel@usgs.gov","middleInitial":"A.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":669908,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Less often considered are the diurnal pattern of tide extremes and seasonal variation of solar insolation in the mix of tidal marsh driver interactions. This work demonstrates how high-frequency hydroperiod and water temperature variability emerges from disparate timescale interactions between tidal marsh morphology, tidal harmonics, and meteorology in the San Francisco Estuary. We compare the tidal and residual flow and temperature response of neighboring tidal sloughs, one possessing natural tidal marsh morphology, and one that is modified for water control. We show that the natural tidal marsh is tuned to lunar phase and produces tidal and fortnight water temperature variability through interacting tide, meteorology, and geomorphic linkages. In contrast, temperature variability is dampened in the modified slough where overbank marsh plain connection is severed by levees. Despite geomorphic differences, a key finding is that both sloughs are heat sinks in summer by latent heat flux-driven residual upstream water advection and sensible and long-wave heat transfer. The precession of a 335-year tidal harmonic assures that these dynamics will shift in the future. Water temperature regulation appears to be a key function of natural tidal sloughs that depends critically on geomorphic mediation. We investigate approaches to untangling the relative influence of sun versus tide on residual water and temperature transport as a function of system morphology. The findings of this study likely have ecological consequences and suggest physical process metrics for tidal marsh restoration performance.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s12237-013-9639-7","usgsCitation":"Enwright, C., Culberson, S., and Burau, J.R., 2013, Broad timescale forcing and geomorphic mediation of tidal marsh flow and temperature dynamics: Estuaries and Coasts, v. 36, no. 6, p. 1319-1339, https://doi.org/10.1007/s12237-013-9639-7.","productDescription":"21 p.","startPage":"1319","endPage":"1339","ipdsId":"IP-039006","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":474050,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s12237-013-9639-7","text":"Publisher Index Page"},{"id":345920,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Suisun Marsh","volume":"36","issue":"6","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationDate":"2013-05-08","publicationStatus":"PW","scienceBaseUri":"59c37e3ce4b091459a631709","contributors":{"authors":[{"text":"Enwright, Christopher","contributorId":196584,"corporation":false,"usgs":false,"family":"Enwright","given":"Christopher","email":"","affiliations":[{"id":34641,"text":"California Delta Science Program","active":true,"usgs":false}],"preferred":false,"id":710854,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Culberson, Steven","contributorId":84284,"corporation":false,"usgs":false,"family":"Culberson","given":"Steven","affiliations":[{"id":6661,"text":"US Fish and Wildlife Service","active":true,"usgs":false}],"preferred":false,"id":710855,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Burau, Jon R. 0000-0002-5196-5035 jrburau@usgs.gov","orcid":"https://orcid.org/0000-0002-5196-5035","contributorId":1500,"corporation":false,"usgs":true,"family":"Burau","given":"Jon","email":"jrburau@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":710853,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This dilemma may be pronounced at range peripheries where rates of change are accelerated and ongoing invasions often are perceived as threats to local ecosystems.

Reserve managers are concerned about P-J woodland encroachment into adjacent sagebrush steppe, but the rates and biophysical variability of encroachment are not well documented and management options are not well understood. We quantified the rate and extent of woodland change between 1950 and 2009 based on a random sample of aerial photo interpretation plots distributed across biophysical gradients. Our study revealed that woodland cover remained at approximately 20% of the study area over the 59-year period. In the absence of disturbance, P-J woodlands exhibited the highest rate of increase among vegetation types at 0.37% yr</span><sup>−1</sup><span>. Overall, late-successional P-J stands increased in area by over 100% through the process of densification (infilling). However, wildfires during the period resulted in a net decrease of woody evergreen vegetation, particularly among early and mid-successional P-J stands. Elevated wildfire risk associated with expanding novel annual grasslands and drought is likely to continue to be a fundamental driver of change in CIRO woodlands. Because P-J woodlands contribute to regional biodiversity and may contract at trailing edges with global warming, CIRO may become important to P-J woodland conservation in the future.

One of the principal causes of the increased risk of post-wildﬁre hydrologically driven hazards is reduced in ﬁltration rates (e.g. Scott and van Wyk, 1990; Cerdà, 1998; Robichaud, 2000; Martin and Moody, 2001). Beyond the reduction in peak inﬁltration rate, there is mounting evidence that the fundamental physics of inﬁltration in wild ﬁre-affected soils is different from unburned soils (e.g. Imeson <i>et al.</i>, 1992; Moody <i>et al.</i>, 2009; Moody and Ebel, 2012).</p><p>Understanding post-wildﬁre hydrology is critical given the increasing wildﬁre incidence in the western USA (Westerling <i>et al.</i>, 2006) and elsewhere in the world (Kasischke and Turetsky, 2006; Holz and Veblen, 2011; Pausas and Fernández-Muñoz, 2012). Wildﬁre is a disturbance event with global distribution (Bowman <i>et al.</i>, 2009; Krawchuk <i>et al.</i>, 2009; Pechony and Shindell, 2010; Moritz<i> et al.</i>, 2012), and with increasing populations moving into ﬁre-prone areas, understanding post-wildﬁre inﬁltration is of increasing importance for predicting post-wildﬁre consequences. Runoff is generally controlled by the inﬁltration-excess mechanism in ﬁre-affected soils (e.g. Mayor <i>et al</i>., 2007; Onda <i>et al.</i>, 2008; Kinner and Moody, 2010). It is essential that the ﬁre community have conceptual models, physical equations and tools (i.e. numerical models) to predict inﬁltration and thus excess rainfall (after Horton, 1933), which can provide estimates of peak discharge, start of runoff, time to peak and total runoff for hydroclimatic scenarios after wildﬁres. Reductions in saturated hydraulic conductivity&nbsp;<i>K</i><sub>sat</sub> [LT<sup>-1</sup>] are common for ﬁre-affected soils, and the relatively low values observed explain the elevated ﬂash ﬂood hazards (e.g.&nbsp;<i>K</i><sub>sat</sub> of 1–100 mm h<sup>-1</sup> , Robichaud, 2000; Yates <i>et al.</i>, 2000; Martin and Moody, 2001; Robichaud <i>et al.</i>, 2007; Moody <i>et al.</i>, 2009; Neary, 2011; Nyman <i>et al.</i>, 2011).</p>","language":"English","publisher":"Wiley","doi":"10.1002/hyp.9696","usgsCitation":"Ebel, B.A., and Moody, J.A., 2013, Rethinking infiltration in wildfire-affected soils: Hydrological Processes, v. 27, no. 10, p. 1510-1514, https://doi.org/10.1002/hyp.9696.","productDescription":"5 p.","startPage":"1510","endPage":"1514","ipdsId":"IP-042674","costCenters":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":344488,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"10","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2013-01-21","publicationStatus":"PW","scienceBaseUri":"59819316e4b0e2f5d463b7a7","contributors":{"authors":[{"text":"Ebel, Brian A. 0000-0002-5413-3963 bebel@usgs.gov","orcid":"https://orcid.org/0000-0002-5413-3963","contributorId":2557,"corporation":false,"usgs":true,"family":"Ebel","given":"Brian","email":"bebel@usgs.gov","middleInitial":"A.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":707008,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moody, John A. 0000-0003-2609-364X jamoody@usgs.gov","orcid":"https://orcid.org/0000-0003-2609-364X","contributorId":771,"corporation":false,"usgs":true,"family":"Moody","given":"John","email":"jamoody@usgs.gov","middleInitial":"A.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":707009,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The use of U–Pb dating on secondary silica to establish the age of Neogene-Quaternary clastic sediments was tested on samples of authigenic and detrital opal and chalcedony from depths of ∼25 to 53&nbsp;m in boreholes at Midway Valley, Nevada. Dating of authigenic opal present as rinds on rock clasts and in calcite/silica cements establishes minimum ages of alluvium deposition; dating of detrital opal or chalcedony derived from the source volcanic rocks gives the maximum age of sediment deposition.</p><p id=\"sp0055\">Materials analyzed included 12 samples of authigenic opal, one sample of fracture-coating opal from bedrock, one sample of detrital opal, and two samples of detrital chalcedony. Uranium–lead isotope data were obtained by both thermal ionization mass spectrometry and ion-microprobe. Uranium concentrations ranged from tens to hundreds of μg/g. Relatively large U/Pb allowed calculation of <sup>206</sup>Pb/<sup>238</sup>U ages that ranged from 1.64±0.36 (2<i>σ</i>) to 6.16±0.50&nbsp;Ma for authigenic opal and from 8.34±0.28 to 11.2±1.3&nbsp;Ma for detrital opal/chalcedony. Three samples with the most radiogenic Pb isotope compositions also allowed calculation of <sup>207</sup>Pb/<sup>235</sup>U ages, which were concordant with <sup>206</sup>Pb/<sup>238</sup>U ages from the same samples.</p><p id=\"sp0060\">These results indicate that basin development at Midway Valley was initiated between about 8 and 6&nbsp;Ma, and that the basin was filled at long-term average deposition rates of less than 1&nbsp;cm/ka. Because alluvium in Midway Valley was derived from adjacent highlands at Yucca Mountain, the low rates of deposition determined in this study may imply a slow rate of erosion of Yucca Mountain. Volcanic strata underlying the basin are offset by a number of buried faults to a greater degree than the relatively smooth-sloping bedrock/alluvium contact. These geologic relations indicate that movement on most faults ceased prior to erosional planation and burial. Therefore, ages of the authigenic opal from basal alluvium indicate that the last movement on buried faults was older than about 6&nbsp;Ma.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.epsl.2012.11.037","usgsCitation":"Neymark, L., and Paces, J.B., 2013, Ion-probe U–Pb dating of authigenic and detrital opal from Neogene-Quaternary alluvium: Earth and Planetary Science Letters, v. 361, p. 98-109, https://doi.org/10.1016/j.epsl.2012.11.037.","productDescription":"12 p.","startPage":"98","endPage":"109","ipdsId":"IP-034248","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":340694,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"361","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"59084936e4b0fc4e448ffd9c","contributors":{"authors":[{"text":"Neymark, Leonid A. 0000-0003-4190-0278 lneymark@usgs.gov","orcid":"https://orcid.org/0000-0003-4190-0278","contributorId":140338,"corporation":false,"usgs":true,"family":"Neymark","given":"Leonid A.","email":"lneymark@usgs.gov","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":693515,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paces, James B. 0000-0002-9809-8493 jbpaces@usgs.gov","orcid":"https://orcid.org/0000-0002-9809-8493","contributorId":2514,"corporation":false,"usgs":true,"family":"Paces","given":"James","email":"jbpaces@usgs.gov","middleInitial":"B.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":693514,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Previous studies demonstrated a strong tidal-mixing front during the warm season on the northern bank margin between thermally stratified water in the Gulf of Maine and mixed water on the bank. Tides transport warm water off the bank during flood tide and cool gulf water onto the bank during ebb tide. During 10 days in August 2009, we mapped frontal temperatures in five study areas along ∼100 km of the bank margin. The seabed “frontal zone”, where temperature changed with frontal movment, experienced semidiurnal temperature maxima and minima. The tidal excursion of the frontal boundary between stratified and mixed water ranged 6 to 10 km. This “frontal boundary zone” was narrower than the frontal zone. Along transects perpendicular to the bank margin, seabed temperature change at individual sites ranged from 7.0°C in the frontal zone to 0.0°C in mixed bank water. At time series in frontal zone stations, changes during tidal cycles ranged from 1.2 to 6.1°C. The greatest rate of change (-2.48°C hr-<sup>1</sup>) occurred at mid-ebb. Geographic plots of seabed temperature change allowed the mapping of up to 8 subareas in each study area. The magnitude of temperature change in a subarea depended on its location in the frontal zone. Frontal movement had the greatest effect on seabed temperature in the 40 to 80 m depth interval. Subareas experiencing maximum temperature change in the frontal zone were not in the frontal boundary zone, but rather several km gulfward (off-bank) of the frontal boundary zone.

From these data, the seismic moment tensor, indicating mostly normal faulting with a small implosive component, and the radiated energy were measured; the deviatoric component of the moment tensor was estimated to be M0 = 2.3×1012 N·m and the radiated energy ER = 5.4×108 J. This event caused extensive damage along tunnels within the Pretorius fault zone. What rendered this earthquake of particular interest was the underground investigation of the complex pattern of exposed rupture surfaces combined with laboratory testing of rock samples retrieved from the ancient fault zone (Heesakkers et al.2011a, 2011b). Event 12/12 2004 was the result of fault slip across at least four nonparallel fault surfaces; 25 mm of slip was measured at one location on the rupture segment that is most parallel with a fault plane inferred from the seismic moment tensor, suggesting that this segment accounted for much of the total seismic deformation. By applying a recently developed technique based on biaxial stick-slip friction experiments (McGarr2012, 2013) to the seismic results, together with the 25 mm slip observed underground, we estimated a maximum slip rate of at least 6.6 m/s, which is consistent with the observed damage to tunnels in the rupture zone. Similarly, the stress drop and apparent stress were found to be correspondingly high at 21.9 MPa and 6.6 MPa, respectively. The ambient state of stress, measured at the approximate depth of the earthquake but away from the influence of mining, in conjunction with laboratory measurements of the strength of the fault zone cataclasites, indicates that during rupture of the M 2.2 event, the normal stress acting on the large-slip fault segment was about 260 MPa, the yield stress was 172 MPa and the seismic efficiency was 0.05. Thus, for event 12/12 2004, 5% of the energy released by the earthquake was radiated and the remaining 95% was consumed in overcoming fault friction and expanding the zone of rupture. </p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proc. 8th International Symposium on Rockbursts and Seismicity in Mines","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Geophysical Survey and Mining Institute of the Russian Academy of Sciences","usgsCitation":"McGarr, A.F., Johnston, M.J., Boettcher, M., Heesakkers, V., and Reches, Z., 2013, Constraints on behaviour of a mining‐induced earthquake inferred from laboratory rock mechanics experiments, <i>in</i> Proc. 8th International Symposium on Rockbursts and Seismicity in Mines, p. 3-10.","productDescription":"8 p.","startPage":"3","endPage":"10","ipdsId":"IP-044866","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":350989,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a7586dee4b00f54eb1d8215","contributors":{"authors":[{"text":"McGarr, Arthur F. 0000-0001-9769-4093 mcgarr@usgs.gov","orcid":"https://orcid.org/0000-0001-9769-4093","contributorId":3178,"corporation":false,"usgs":true,"family":"McGarr","given":"Arthur","email":"mcgarr@usgs.gov","middleInitial":"F.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":715989,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnston, Malcolm J.

Data are from four sources: the Smithsonian Institution, Witham (2005), CRED EM-DAT and Munich RE. The data were combined and formatted, with a weighted average fatality figure used where more than one source reports an event; the former two databases were weighted twice as strongly as the latter two. More fatal incidents are contained within our database than similar previous works; approximately 46% of the fatal incidents are listed in only one of the four sources, and fewer than 10% are in all four. 278,880 fatalities are recorded in the database, resultant from 533 fatal incidents. The fatality count is dominated by a handful of disasters, though the majority of fatal incidents have caused fewer than ten fatalities. Number and empirical probability of fatalities are broadly correlated with VEI, but are more strongly influenced by population density around volcanoes and the occurrence and extent of lahars (mudflows) and pyroclastic density currents, which have caused 50% of fatalities. Indonesia, the Philippines, and the West Indies dominate the spatial distribution of fatalities, and there is some negative correlation between regional development and number of fatalities. With the largest disasters removed, over 90% of fatalities occurred between 5 km and 30 km from volcanoes, though the most devastating eruptions impacted far beyond these distances. A new measure, the Volcano Fatality Index, is defined to explore temporal changes in societal vulnerability to volcanic hazards. The measure incorporates population growth and recording improvements with the fatality data, and shows<span>&nbsp;</span><i class=\"EmphasisTypeItalic\">prima facie</i><span>&nbsp;</span>evidence that vulnerability to volcanic hazards has fallen during the last two centuries. Results and interpretations are limited in scope by the underlying fatalities data, which are affected by under-recording, uncertainty, and bias. Attempts have been made to estimate the extent of these issues, and to remove their effects where possible.</p><p class=\"Para\">The data analysed here are provided as supplementary material.

High-resolution analyses of fossil pollen from one core locality revealed a continuously shifting sequence of thermally dependent forest assemblages, ranging between two endmembers: subtropical oak-tupelo-bald cypress-gum forest and high boreal spruce-pine forest. Sedimentary textural evidence indicates fluvial, paludal, and loess deposition, and paleosol formation, representing sequential freshwater to subaerial environments in which this record was deposited. Its total age\"depth model, based on radiocarbon and optically stimulated luminescence ages, ranges from terrestrial oxygen isotope stages (OIS) 6 to 1. The particular core sub-interval presented here is correlative in trend and timing to that portion of the oxygen isotope sequence common among several Greenland ice cores: interstades GI2 to GI24 (≈ OIS2–5 d). This site thus provides the first evidence for an essentially complete series of \"Dansgaard\"Oeschger\" climate events in the MAR.

Several simulations using uniform distributions of factors show that the product distribution has a central peak approximately centered at the product of the medians of the factor distributions. Factor distributions that are peaked, such as Gaussian (normal) produce an even more peaked product distribution. Piecewise analytic solutions can be obtained for independent factor distributions and yield insight into the properties of the product distribution. As an example, porphyry copper grades and tonnages are now available in at least one public database and their distributions were analyzed. Although both grade and tonnage can be approximated with lognormal distributions, they are not exactly fit by them. The grade shows some nonlinear correlation with tonnage for the published database. Sampling by deposit from available databases of grade, tonnage, and geological details of each deposit specifies both grade and tonnage for that deposit. Any correlation between grade and tonnage is then preserved and the observed distribution of grades and tonnages can be used with no assumption of distribution form.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s11053-013-9206-8","usgsCitation":"Gettings, M.E., 2013, Monte Carlo simulations of product distributions and contained metal estimates: Natural Resources Research, v. 22, no. 3, p. 239-254, https://doi.org/10.1007/s11053-013-9206-8.","productDescription":"16 p.","startPage":"239","endPage":"254","ipdsId":"IP-045215","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":342941,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"22","issue":"3","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2013-04-12","publicationStatus":"PW","scienceBaseUri":"59536eaee4b062508e3c7ab7","contributors":{"authors":[{"text":"Gettings, Mark E. 0000-0002-2910-2321 mgetting@usgs.gov","orcid":"https://orcid.org/0000-0002-2910-2321","contributorId":602,"corporation":false,"usgs":true,"family":"Gettings","given":"Mark","email":"mgetting@usgs.gov","middleInitial":"E.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":700748,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Test species included two unionid mussels (rainbow mussel, <i>Villosa iris</i>, and wavy-rayed lampmussel, <i>Lampsilis fasciola</i>, 28-d exposures), and the commonly tested amphipod, <i>Hyalella azteca</i> (28-d exposure) and midge, <i>Chironomus dilutus</i> (10-d exposure). Sediments were collected from seven test sites with mussel communities classified as impacted and in proximity to coal mining or gas extraction activities, and from five reference sites with mussel communities classified as not impacted and no or limited coal mining or gas extraction activities. Additional samples were collected from six test sites potentially with high concentrations of polycyclic aromatic hydrocarbons (PAHs) and from a test site contaminated by a coal ash spill. Mean survival, length, or biomass of one or more test species was reduced in 10 of 14 test samples (71%) from impacted areas relative to the response of organisms in the five reference samples. A higher proportion of samples was classified as toxic to mussels (63% for rainbow mussels, 50% for wavy-rayed lampmussels) compared with amphipods (38%) or midge (38%). Concentrations of total recoverable metals and total PAHs in sediments did not exceed effects-based probable effect concentrations (PECs). However, the survival, length, or biomasses of the mussels were reduced significantly with increasing PEC quotients for metals and for total PAHs, or with increasing sum equilibrium-partitioning sediment benchmark toxic units for PAHs. The growth of the rainbow mussel also significantly decreased with increasing concentrations of a major anion (chloride) and major cations (calcium and magnesium) in sediment pore water. Results of the present study indicated that (1) the findings from laboratory tests were generally consistent with the field observations of impacts on mussel populations; (2) total recoverable metals, PAHs, or major ions, or all three in sediments might have contributed to the sediment toxicity; (3) the mussels were more sensitive to the contaminants in sediments than the commonly tested amphipod and midge; and (4) a sediment toxicity benchmark of 1.0 based on PECs may not be protective of mussels.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1002/etc.2032","usgsCitation":"Wang, N., Ingersoll, C.G., Kunz, J.L., Brumbaugh, W.G., Kane, C.M., Evans, R.B., Alexander, S., Walker, C., and Bakaletz, S., 2013, Toxicity of sediments potentially contaminated by coal mining and natural gas extraction to unionid mussels and commonly tested benthic invertebrates: Environmental Toxicology and Chemistry, v. 32, no. 1, p. 207-221, https://doi.org/10.1002/etc.2032.","productDescription":"15 p.","startPage":"207","endPage":"221","ipdsId":"IP-038575","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":264803,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.41,24.52 ], [ -124.41,49.0 ], [ -66.9,49.0 ], [ -66.9,24.52 ], [ -124.41,24.52 ] ] ] } } ] }","volume":"32","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-10-15","publicationStatus":"PW","scienceBaseUri":"50e553d0e4b0a4aa5bb021d9","contributors":{"authors":[{"text":"Wang, Ning 0000-0002-2846-3352 nwang@usgs.gov","orcid":"https://orcid.org/0000-0002-2846-3352","contributorId":2818,"corporation":false,"usgs":true,"family":"Wang","given":"Ning","email":"nwang@usgs.gov","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":470398,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ingersoll, Christopher G. 0000-0003-4531-5949 cingersoll@usgs.gov","orcid":"https://orcid.org/0000-0003-4531-5949","contributorId":2071,"corporation":false,"usgs":true,"family":"Ingersoll","given":"Christopher","email":"cingersoll@usgs.gov","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":470397,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kunz, James L. 0000-0002-1027-158X jkunz@usgs.gov","orcid":"https://orcid.org/0000-0002-1027-158X","contributorId":3309,"corporation":false,"usgs":true,"family":"Kunz","given":"James","email":"jkunz@usgs.gov","middleInitial":"L.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":470399,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brumbaugh, William G. 0000-0003-0081-375X bbrumbaugh@usgs.gov","orcid":"https://orcid.org/0000-0003-0081-375X","contributorId":493,"corporation":false,"usgs":true,"family":"Brumbaugh","given":"William","email":"bbrumbaugh@usgs.gov","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":470396,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kane, Cindy M.","contributorId":9549,"corporation":false,"usgs":true,"family":"Kane","given":"Cindy","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":470400,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Evans, R.

Habitat disturbance has affected populations of feeding specialists most profoundly, and our results indicate that specialists continue to be most vulnerable, although even some abundant, introduced, generalist species also may be affected. Surveys of passerines during 1998–2011 in subalpine woodland habitat on Mauna Kea Volcano, Island of Hawai′i, revealed that the abundance of the critically endangered palila (<i>Loxioides bailleui</i>), a seed specialist, declined by 79% after 2003. The ′akiapōlā′au (<i>Hemignathus munroi</i>), an endangered specialist insectivore, was not detected in the survey area after 1998. The Hawai′i ′amakihi (<i>Hemignathus virens virens</i>), a generalist feeder and the most abundant species on Mauna Kea, was the only native species to maintain a stable population. The Japanese white-eye (<i>Zosterops japonicus</i>), a well-entrenched generalist and one of the three most common introduced species, declined. Drought prevailed in 74% of months during 2000–2011, and dry conditions contributed to the recent decline of the palila by reducing the annual māmane (<i>Sophora chrysophylla</i>) seed pod crop, which influences palila breeding and survival. Sustained browsing by introduced ungulates also lowered habitat carrying capacity, and their elimination should reduce the effects of drought and promote forest restoration. Our results illustrate how the feeding ecology of a species can influence its response to interacting environmental perturbations, and they underscore the value of long-term monitoring to detect population trends of sensitive species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.biocon.2012.07.013","usgsCitation":"Banko, P.C., Camp, R., Farmer, C., Brinck, K., Leonard, D., and Stephens, R., 2013, Response of palila and other subalpine Hawaiian forest bird species to prolonged drought and habitat degradation by feral ungulates: Biological Conservation, v. 157, p. 70-77, https://doi.org/10.1016/j.biocon.2012.07.013.","productDescription":"8 p.","startPage":"70","endPage":"77","ipdsId":"IP-038330","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":263889,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263888,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2012.07.013"}],"country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -178.31,18.91 ], [ -178.31,28.4 ], [ -154.81,28.4 ], [ -154.81,18.91 ], [ -178.31,18.91 ] ] ] } } ] }","volume":"157","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50c46198e4b0e44331d07178","contributors":{"authors":[{"text":"Banko, Paul C. 0000-0002-6035-9803 pbanko@usgs.gov","orcid":"https://orcid.org/0000-0002-6035-9803","contributorId":3179,"corporation":false,"usgs":true,"family":"Banko","given":"Paul","email":"pbanko@usgs.gov","middleInitial":"C.","affiliations":[{"id":5049,"text":"Pacific Islands Ecosys Research Center","active":true,"usgs":true},{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"preferred":true,"id":469946,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Camp, Richard J.","contributorId":27392,"corporation":false,"usgs":true,"family":"Camp","given":"Richard J.","affiliations":[],"preferred":false,"id":469949,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Farmer, Chris cfarmer@usgs.gov","contributorId":3681,"corporation":false,"usgs":true,"family":"Farmer","given":"Chris","email":"cfarmer@usgs.gov","affiliations":[],"preferred":true,"id":469947,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brinck, Kevin W.","contributorId":78215,"corporation":false,"usgs":true,"family":"Brinck","given":"Kevin W.","affiliations":[],"preferred":false,"id":469950,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Leonard, David L.","contributorId":105191,"corporation":false,"usgs":true,"family":"Leonard","given":"David L.","affiliations":[],"preferred":false,"id":469951,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stephens, Robert M.","contributorId":11083,"corporation":false,"usgs":true,"family":"Stephens","given":"Robert M.","affiliations":[],"preferred":false,"id":469948,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The Mississippi Delta has long been known for its fish productivity and recreational value, but high levels of P in fresh water can lead to algal blooms that have many detrimental effects on natural ecosystems. Algal blooms interfere with recreational and aesthetic water use. However, few studies have evaluated P losses from agricultural watersheds in the Mississippi Delta. To better understand the processes influencing P loss, rainfall, surface runoff, sediment, ortho-P (orthophosphate, PO</span><sub>4</sub><span>&ndash;P), and total P (TP) were measured (water years 1996&ndash;2000) for two subwatersheds (UL1 and UL2) of the Deep Hollow Lake Watershed and one subwatershed of the Beasley Lake Watershed (BL3) primarily in cotton production in the Mississippi Delta. Ortho-P concentrations ranged from 0.01 to 1.0&nbsp;mg/L with a mean of 0.17&nbsp;mg/L at UL1 (17.0&nbsp;ha), 0.36&nbsp;mg/L at UL2 (11.2&nbsp;ha) and 0.12&nbsp;mg/L at BL3 (7.2&nbsp;ha). The TP concentrations ranged from 0.14 to 7.9&nbsp;mg/L with a mean of 0.96&nbsp;mg/L at UL1, 1.1&nbsp;mg/L at UL2 and 1.29&nbsp;mg/L at BL3. Among the three sites, UL1 and UL2 received P&nbsp;application in October 1998, and BL3 received P applications in the spring of 1998 and 1999. At UL1, ortho-P concentrations were 0.36, 0.25 and 0.16 for the first, second and third rainfall events after P&nbsp;application, respectively; At UL2, ortho-P concentrations were 1.0, 0.66 and 0.65 for the first, second and third rainfall events after P application, respectively; and at BL3, ortho-P concentrations were 0.11, 0.22 and 0.09 for the first, second and third rainfall events after P application, respectively. P fertilizer application did influence P losses, but high P concentrations observed in surface runoff were not always a direct result of P fertilizer application or high rainfall. Application of P in the fall (UL1 and UL2) resulted in more ortho-P losses, likely because high rainfall often occurred in the winter months soon after application. The mean ortho-P concentrations were higher at UL1 and UL2 than those at BL3, although BL3 received more P application during the monitoring period, because P was applied in spring at BL3. However, tillage associated with planting and incorporating applied P in the spring (BL3) may have resulted in more TP loss in sediment, thus the mean TP concentration was the highest at BL3. Ortho-P loss was correlated with surface runoff; and TP loss was correlated with sediment loss. These results indicate that applying P fertilizer in the spring may be recommended to reduce potential ortho-P loss during the fallow winter season; in addition, conservation practices may reduce potential TP loss associated with soil loss.</span></p>","language":"English","publisher":"Elsevier Ltd.","publisherLocation":"Oxford, UK","doi":"10.1016/j.jenvman.2012.10.028","usgsCitation":"Yuan, Y., Locke, M.A., Bingner, R.L., and Rebich, R.A., 2013, Phosphorus losses from agricultural watersheds in the Mississippi Delta: Journal of Environmental Management, v. 115, p. 14-20, https://doi.org/10.1016/j.jenvman.2012.10.028.","productDescription":"7 p.","startPage":"14","endPage":"20","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-042679","costCenters":[{"id":394,"text":"Mississippi Water Science Center","active":true,"usgs":true}],"links":[{"id":314695,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Mississippi","county":"Leflore County, Sunflower County","otherGeospatial":"Beasley Lake watershed, Deep Hollow Lake watershed, Mississippi Delta","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -90.76492309570312,\n              33.27084277265288\n            ],\n            [\n              -90.76492309570312,\n              33.47956309444182\n            ],\n            [\n              -90.09201049804688,\n              33.47956309444182\n            ],\n            [\n              -90.09201049804688,\n              33.27084277265288\n            ],\n            [\n              -90.76492309570312,\n              33.27084277265288\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"115","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56a360c0e4b0b28f1183bc12","contributors":{"authors":[{"text":"Yuan, Yongping","contributorId":75799,"corporation":false,"usgs":true,"family":"Yuan","given":"Yongping","email":"","affiliations":[],"preferred":false,"id":589458,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Locke, Martin A.","contributorId":152468,"corporation":false,"usgs":false,"family":"Locke","given":"Martin","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":589459,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bingner, Ronald L.","contributorId":152469,"corporation":false,"usgs":false,"family":"Bingner","given":"Ronald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":589460,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rebich, Richard A. 0000-0003-4256-7171 rarebich@usgs.gov","orcid":"https://orcid.org/0000-0003-4256-7171","contributorId":2315,"corporation":false,"usgs":true,"family":"Rebich","given":"Richard","email":"rarebich@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":589416,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The Blue Gem, characterized by low ash yield and low sulfur content, is an important economic resource. Past studies have characterized the Blue Gem's geochemistry, palynology and petrography and inferred a depositional setting of a planar peat deposit that transitioned to slightly domed later in its development. These studies have focused primarily on vertical geochemical trends within the coal bed. Simulated maps of chemical elements derived from 45 measured sample locations across the study area provide an opportunity to observe changes in the horizontal direction within the coal bed. As the Blue Gem coal bed shows significant vertical chemical trends, care was taken in this study to try to select samples from a single, middle portion of the coal. By revealing spatial distribution patterns of elements across the middle of the bed, associations between different components of the coal can be seen. The maps therefore help to provide a picture of the coal-forming peat bog at an instant in geologic time and allow interpretation of a depositional setting in the horizontal direction. Results from this middle portion of the coal suggest an association of SiO<sub>2</sub> with both K<sub>2</sub>O and TiO<sub>2</sub> in different parts of the study area. Further, a pocket in the southeast of the study area shows elevated concentrations of elements attributable to observed carbonate-phase minerals (MgO, CaO, Ba and Sr) as well as elements commonly associated with sulfide-phase minerals (Cu, Mo and Ni). Areas of relatively high ash yield are observed in the north and south of the mapped area, in contrast to the low ash yields seen towards the east. Additionally, we present joint probability maps where multiple coal-quality parameters are plotted simultaneously on one figure. This application allows researchers to investigate associations of more than two components in a straight-forward manner useful in guiding resource exploration.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal of Coal Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.coal.2012.10.010","usgsCitation":"Geboy, N., Olea, R., Engle, M.A., and Martin-Fernandez, J.A., 2013, Using simulated maps to interpret the geochemistry, formation and quality of the Blue Gem Coal Bed, Kentucky, USA: International Journal of Coal Geology, v. 112, 10 p., https://doi.org/10.1016/j.coal.2012.10.010.","productDescription":"10 p.","ipdsId":"IP-039031","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":263545,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263544,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.coal.2012.10.010"}],"country":"United States","state":"Kentucky","otherGeospatial":"Blue Gem","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -89.5693,36.4972 ], [ -89.5693,39.1475 ], [ -81.965,39.1475 ], [ -81.965,36.4972 ], [ -89.5693,36.4972 ] ] ] } } ] }","volume":"112","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e56508e4b0a4aa5bb04b56","contributors":{"authors":[{"text":"Geboy, Nicholas J. ngeboy@usgs.gov","contributorId":3860,"corporation":false,"usgs":true,"family":"Geboy","given":"Nicholas J.","email":"ngeboy@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":469477,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Olea, Ricardo A. 0000-0003-4308-0808","orcid":"https://orcid.org/0000-0003-4308-0808","contributorId":47873,"corporation":false,"usgs":true,"family":"Olea","given":"Ricardo A.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":469478,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Engle, Mark A. 0000-0001-5258-7374 engle@usgs.gov","orcid":"https://orcid.org/0000-0001-5258-7374","contributorId":584,"corporation":false,"usgs":true,"family":"Engle","given":"Mark","email":"engle@usgs.gov","middleInitial":"A.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":469476,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Martin-Fernandez, Jose Antonio","contributorId":83002,"corporation":false,"usgs":true,"family":"Martin-Fernandez","given":"Jose","email":"","middleInitial":"Antonio","affiliations":[],"preferred":false,"id":469479,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Whole-rock major-element data for the granulites suggest affinities with tholeiitic basalts. P–T estimates for granulites indicate peak temperatures of 690–730°C and pressures of 9–12 kbar, consistent with seismic estimates of crustal thickness in the region. The granulites can be divided into two groups based on trace-element characteristics. Group 1 granulites have trace-element signatures similar to average Archean lower crust; they are light rare earth element (LREE)-enriched, with high La/Nb ratios and positive Pb anomalies. Most plot to the left of the geochron on a <sup>206</sup>Pb/<sup>€204</sup>Pb vs <sup>207</sup>Pb/<sup>€204</sup>Pb diagram, and there was probably widespread incorporation of Proterozoic to Archean components into the magmatic protoliths of these rocks. Although the age of the Group 1 granulites is not well constrained, their protoliths appear to be have been emplaced during the Mesoproterozoic and to be older than those for Group 2 granulites. Group 2 granulites are also LREE-enriched, but have strong positive Nb and Ta anomalies and low La/Nb ratios, suggesting intraplate magmatic affinities. They have trace-element characteristics similar to those of some Mid-Continent Rift (Keweenawan) basalts. They yield a Sm–Nd whole-rock errorchron age of 1046 ± 140 Ma, similar to that of Mid-Continent Rift plume magmatism. These granulites have unusually radiogenic Pb isotope compositions that plot above the <sup>207</sup>Pb/<sup>€204</sup>Pb vs <sup>206</sup>Pb/<sup>€204</sup>Pb growth curve and to the right of the 4·55 Ga geochron, and closely resemble the Pb isotope array defined by Mid-Continent Rift basalts. These Pb isotope data indicate that ancient continental lower crust is not uniformly depleted in U (and Th) relative to Pb. One granulite xenolith, S69-5, contains quartz, and has a unique peraluminous composition. It has the lowest εNd and εHf values of the suite. Its isotopic compositions indicate that it is significantly older than the other granulites. Broken zircon cores encased by younger overgrowths suggest that this granulite includes a large component of pre-existing sedimentary rocks. Two distinct populations of zircons from S69-5 were dated by sensitive high-resolution ion microprobe. Abundant rounded zircons yield ages of 1104 ± 42 (2σ) Ma, which coincide with the Mid-Continent Rift flood basalt eruptions. Their morphology is similar to those found in lower-crustal rocks that have undergone granulite-facies metamorphism and thus they are considered to represent the age of Group 2 granulites. Also present are less abundant elongate zircon grains that yield a mean age of 1387 ± 32 (2σ) Ma. Their elongate shapes indicate growth from a melt or fluid, possibly associated with 1·3–1·5 Ga anorogenic granite magmatism exposed in the shallow crust to the south in Wisconsin, or related to an initial encroachment of the Keweenawan plume upon the lower crust. Older ages recognized in zircon cores are less well constrained but may be related to tectono-magmatic events in the southern Superior craton. Within the studied suite only S69-5 was recognized as a remnant of the Late Archean lower crust into which the Group 1 and 2 mafic granulite precursor basalts were intruded. Collectively, the data show that the lower crust beneath northern Michigan formed in Archean times and underwent a variety of tectono-magmatic processes throughout the Proterozoic, including orogenesis, partial melting and mafic magmatic underplating in response to upwelling mantle plumes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Oxford Journals","publisherLocation":"Oxford, U.K.","doi":"10.1093/petrology/egs079","usgsCitation":"Zartman, R.E., Kempton, P.D., Paces, J.B., Downes, H., Williams, I.S., Dobosi, G., and Futa, K., 2013, Lower-crustal xenoliths from Jurassic kimberlite diatremes, upper Michigan (USA): Evidence for Proterozoic orogenesis and plume magmatism in the lower crust of the southern Superior Province: Journal of Petrology, v. 54, no. 3, p. 575-608, https://doi.org/10.1093/petrology/egs079.","productDescription":"14 p.","startPage":"575","endPage":"608","ipdsId":"IP-040583","costCenters":[{"id":308,"text":"Geology and Environmental Change Science Center","active":false,"usgs":true}],"links":[{"id":474062,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/petrology/egs079","text":"Publisher Index Page"},{"id":263561,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263560,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1093/petrology/egs079"}],"country":"United States","state":"Michigan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -90.42,41.7 ], [ -90.42,48.29 ], [ -82.41,48.29 ], [ -82.41,41.7 ], [ -90.42,41.7 ] ] ] } } ] }","volume":"54","issue":"3","noUsgsAuthors":false,"publicationDate":"2012-11-22","publicationStatus":"PW","scienceBaseUri":"50dfa812e4b0dfbe79e6e4a3","contributors":{"authors":[{"text":"Zartman, Robert E.","contributorId":47356,"corporation":false,"usgs":true,"family":"Zartman","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":469428,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kempton, Pamela D.","contributorId":80994,"corporation":false,"usgs":true,"family":"Kempton","given":"Pamela","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":469430,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Paces, James B. 0000-0002-9809-8493 jbpaces@usgs.gov","orcid":"https://orcid.org/0000-0002-9809-8493","contributorId":2514,"corporation":false,"usgs":true,"family":"Paces","given":"James","email":"jbpaces@usgs.gov","middleInitial":"B.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":469425,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Downes, Hilary","contributorId":13508,"corporation":false,"usgs":true,"family":"Downes","given":"Hilary","email":"","affiliations":[],"preferred":false,"id":469426,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Williams, Ian S.","contributorId":77439,"corporation":false,"usgs":true,"family":"Williams","given":"Ian","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":469429,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Dobosi, Gabor","contributorId":47264,"corporation":false,"usgs":true,"family":"Dobosi","given":"Gabor","email":"","affiliations":[],"preferred":false,"id":469427,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Futa, Kiyoto 0000-0001-8649-7510 kfuta@usgs.gov","orcid":"https://orcid.org/0000-0001-8649-7510","contributorId":619,"corporation":false,"usgs":true,"family":"Futa","given":"Kiyoto","email":"kfuta@usgs.gov","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":469424,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Here we report and genetically characterize the nascent invasion of Puerto Rico by an exotic constricting snake of the family Boidae (<i>Boa constrictor</i>) using mtDNA and microsatellite data. Over 150 individual <i>B. constrictor</i> have been removed from Mayagüez municipality since May 2011, and our results from the genetic analysis of 32 individuals suggest that this population was recently founded by individuals of one subspecies from a genetic lineage common to zoo and breeding collections, but that the potential propagule pool consists of two subspecies. We also suggest that anthropogenic long-distance dispersal within the island of Puerto Rico may be occurring from the established population, with implications for further establishment across the island. This study represents the first report of the naturalization of an invasive species of boid snake in Puerto Rico and will be important in determining mitigation strategies for this invasion as well as providing a basis for comparison to other on-going studies of invasive snakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Invasions","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10530-012-0354-2","usgsCitation":"Reynolds, R., Puente-Rolon, A.R., Reed, R., and Revell, L.J., 2013, Genetic analysis of a novel invasion of Puerto Rico by an exotic constricting snake: Biological Invasions, v. 15, no. 5, p. 953-959, https://doi.org/10.1007/s10530-012-0354-2.","productDescription":"7 p.","startPage":"953","endPage":"959","ipdsId":"IP-040400","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":263510,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263507,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10530-012-0354-2"}],"country":"Puerto Rico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -67.9455,17.8814 ], [ -67.9455,18.516 ], [ -65.2211,18.516 ], [ -65.2211,17.8814 ], [ -67.9455,17.8814 ] ] ] } } ] }","volume":"15","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-11-29","publicationStatus":"PW","scienceBaseUri":"50dd67f2e4b0e31bb027dbdc","contributors":{"authors":[{"text":"Reynolds, R.

Because nutcracker seed dispersal services are key to maintaining viable populations of these imperiled pines, knowledge of movement patterns of Clark’s nutcrackers helps managers understand local extinction risks for these trees. To investigate population structure within Clark’s nutcracker, we developed primers for and characterized 13 polymorphic microsatellite loci. In a screen of 22 individuals from one population, levels of variability ranged from 6 to 15 alleles. No loci were found to be linked, although 4 loci revealed significant departures from Hardy–Weinberg equilibrium and evidence of null alleles. These microsatellite loci will enable population genetic analyses of Clark’s nutcrackers, which could provide insights into the spatial relationships between nutcrackers and the trees they help disperse.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Conservation Genetics Resources","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s12686-012-9789-0","usgsCitation":"Oyler-McCance, S.J., Fike, J., Castoe, T.A., Tomback, D.F., Wunder, M.B., and Schaming, T.D., 2013, Development and characterization of thirteen microsatellite loci in Clark's nutcracker (Nucifraga columbiana): Conservation Genetics Resources, v. 5, no. 2, p. 303-305, https://doi.org/10.1007/s12686-012-9789-0.","productDescription":"3 p.","startPage":"303","endPage":"305","ipdsId":"IP-041278","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":263354,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263353,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s12686-012-9789-0"}],"volume":"5","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-10-09","publicationStatus":"PW","scienceBaseUri":"50b1ec82e4b0d1ade0ddf940","contributors":{"authors":[{"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":467895,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fike, Jennifer A.","contributorId":54468,"corporation":false,"usgs":true,"family":"Fike","given":"Jennifer A.","affiliations":[],"preferred":false,"id":467897,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Castoe, Todd A.","contributorId":23819,"corporation":false,"usgs":true,"family":"Castoe","given":"Todd","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":467896,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tomback, Diana F.","contributorId":69427,"corporation":false,"usgs":true,"family":"Tomback","given":"Diana","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":467899,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wunder, Michael B.","contributorId":88594,"corporation":false,"usgs":true,"family":"Wunder","given":"Michael","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":467900,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Schaming, Taza D.","contributorId":54867,"corporation":false,"usgs":true,"family":"Schaming","given":"Taza","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":467898,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}
