These landscape changes are linked to enhanced fluxes of carbon and nitrogen pollution from the Mississippi River, and persistent eutrophication and hypoxia in the northern Gulf of Mexico. Increased terrestrial runoff is one hypothesis for recent enrichment in bulk nitrogen isotope (δ<sup>15</sup>N) values, a tracer for nutrient source, observed in a Gulf of Mexico deep-sea coral record. However, unambiguously linking anthropogenic land use change to whole scale shifts in downstream Gulf of Mexico biogeochemical cycles is difficult. Here we present a novel approach, coupling a new tracer of agro-industrialization to a multiproxy record of nutrient loading in long-lived deep-sea corals collected in the Gulf of Mexico. We found that coral bulk δ<sup>15</sup>N values are enriched over the last 150–200 years relative to the last millennia, and compound-specific amino acid δ<sup>15</sup>N data indicate a strong increase in baseline δ<sup>15</sup>N of nitrate as the primary cause. Coral rhenium (Re) values are also strongly elevated during this period, suggesting that 34% of Re is of anthropogenic origin, consistent with Re enrichment in major world rivers. However, there are no pre-anthropogenic measurements of Re to confirm this observation. For the first time, an unprecedented record of natural and anthropogenic Re variability is documented through coral Re records. Taken together, these novel proxies link upstream changes in water quality to impacts on the deep-sea coral ecosystem.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Global Biogeochemical Cycles","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/2013GB004754","usgsCitation":"Prouty, N.G., Roark, E., Koenig, A.E., Demopoulos, A., Batista, F.C., Kocar, B.D., Selby, D., McCarthy, M.D., and Mienis, F., 2014, Deep-sea coral record of human impact on watershed quality in the Mississippi River Basin: Global Biogeochemical Cycles, v. 28, no. 1, p. 29-43, https://doi.org/10.1002/2013GB004754.","productDescription":"15 p.","startPage":"29","endPage":"43","numberOfPages":"15","ipdsId":"IP-051800","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":473237,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"text":"External Repository"},{"id":285751,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285750,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/2013GB004754"}],"country":"United States","otherGeospatial":"Mississippi River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.0,24.0 ], [ -116.0,48.0 ], [ -76.0,48.0 ], [ -76.0,24.0 ], [ -116.0,24.0 ] ] ] } } ] }","volume":"28","issue":"1","noUsgsAuthors":false,"publicationDate":"2014-01-24","publicationStatus":"PW","scienceBaseUri":"53559002e4b0120853e8beb3","contributors":{"authors":[{"text":"Prouty, Nancy G. 0000-0002-8922-0688 nprouty@usgs.gov","orcid":"https://orcid.org/0000-0002-8922-0688","contributorId":3350,"corporation":false,"usgs":true,"family":"Prouty","given":"Nancy","email":"nprouty@usgs.gov","middleInitial":"G.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":492406,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roark, E.

However, few studies have considered the spatial and temporal overlap of these threats to evaluate how ongoing land-use change could affect species ranges projected to shift outside conservation areas. We evaluated climate change and urban development effects on vegetation distribution in the Southwest ecoregion, California Floristic Province, USA. We also evaluated how well a conservation network protects suitable habitat for rare plant species under these change projections and identified primary sources of uncertainty. We used consensus-based maps from three species distribution models (SDMs) to project current and future suitable habitat for 19 species representing different functional types (defined by fire-response – obligate seeders, resprouting shrubs – and life forms – herbs, subshrubs), and range sizes (large/common, small/rare). We used one spatially explicit urban growth projection; two climate models, emission scenarios, and probability thresholds applied to SDMs; and high-resolution (90&nbsp;m) environmental data. We projected that suitable habitat could disappear for 4 species and decrease for 15 by 2080. Averaged centroids of suitable habitat (all species) were projected to shift tens (up to hundreds) of kilometers. Herbs showed a small-projected response to climate change, while obligate seeders could suffer the greatest losses. Several rare species could lose suitable habitat inside conservation areas while increasing area outside. We concluded that (i) climate change is more important than urban development for vegetation habitat loss in this ecoregion through 2080 due to diminishing amounts of undeveloped private land in this region; (ii) the existing conservation plan, while extensive, may be inadequate to protect plant diversity under projected patterns of climate change and urban development, (iii) regional assessments of the dynamics of the drivers of biodiversity change based on high-resolution environmental data and consensus predictive mapping, such as this study, are necessary to identify the species expected to be the most vulnerable and to meaningfully inform regional-scale conservation.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/13658816.2013.846472","usgsCitation":"Beltran, B., Franklin, J., Syphard, A.D., Regan, H.M., Flint, L.E., and Flint, A.L., 2014, Effects of climate change and urban development on the distribution and conservation of vegetation in a Mediterranean type ecosystem: International Journal of Geographical Information Science, v. 28, no. 8, p. 1561-1589, https://doi.org/10.1080/13658816.2013.846472.","productDescription":"29 p.","startPage":"1561","endPage":"1589","ipdsId":"IP-041948","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":473238,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/4zf1737x","text":"External Repository"},{"id":357986,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.94921874999999,\n              32.519026027827515\n            ],\n            [\n              -115.850830078125,\n              32.519026027827515\n            ],\n            [\n              -115.850830078125,\n              34.161818161230386\n            ],\n            [\n              -117.94921874999999,\n              34.161818161230386\n            ],\n            [\n              -117.94921874999999,\n              32.519026027827515\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"28","issue":"8","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationDate":"2013-10-18","publicationStatus":"PW","scienceBaseUri":"5bc038ebe4b0fc368eb53b15","contributors":{"authors":[{"text":"Beltran, Bray","contributorId":197901,"corporation":false,"usgs":false,"family":"Beltran","given":"Bray","email":"","affiliations":[],"preferred":false,"id":746933,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Franklin, Janet","contributorId":192373,"corporation":false,"usgs":false,"family":"Franklin","given":"Janet","affiliations":[],"preferred":false,"id":746935,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Syphard, Alexandra D.","contributorId":8977,"corporation":false,"usgs":false,"family":"Syphard","given":"Alexandra","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":746932,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Regan, Helen M.","contributorId":149953,"corporation":false,"usgs":false,"family":"Regan","given":"Helen","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":746934,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Flint, Lorraine E. 0000-0002-7868-441X lflint@usgs.gov","orcid":"https://orcid.org/0000-0002-7868-441X","contributorId":1184,"corporation":false,"usgs":true,"family":"Flint","given":"Lorraine","email":"lflint@usgs.gov","middleInitial":"E.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":746931,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Flint, Alan L. 0000-0002-5118-751X aflint@usgs.gov","orcid":"https://orcid.org/0000-0002-5118-751X","contributorId":1492,"corporation":false,"usgs":true,"family":"Flint","given":"Alan","email":"aflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":746930,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Still, many commonalities exist due to the physical basis of many of the properties and categories. An abstract ontology of surface water features based only on those physical properties of landscape features has the best potential for serving as a foundational domain ontology for other more context-dependent ontologies. The Surface Water ontology design pattern was developed both for domain knowledge distillation and to serve as a conceptual building-block for more complex or specialized surface water ontologies. A fundamental distinction is made in this ontology between landscape features that act as containers (e.g., stream channels, basins) and the bodies of water (e.g., rivers, lakes) that occupy those containers. Concave (container) landforms semantics are specified in a Dry module and the semantics of contained bodies of water in a Wet module. The pattern is implemented in OWL, but Description Logic axioms and a detailed explanation is provided in this paper. The OWL ontology will be an important contribution to Semantic Web vocabulary for annotating surface water feature datasets. Also provided is a discussion of why there is a need to complement the pattern with other ontologies, especially the previously developed Surface Network pattern. Finally, the practical value of the pattern in semantic querying of surface water datasets is illustrated through an annotated geospatial dataset and sample queries using the classes of the Surface Water pattern.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Geographic Information Science: Proceedings of the 8th International Conference, GIScience","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Springer","doi":"10.1007/978-3-319-11593-1_13","usgsCitation":"Sinha, G., Mark, D., Kolas, D., Varanka, D., Romero, B.E., Feng, C., Usery, E.L., Liebermann, J., and Sorokine, A., 2014, An ontology design pattern for surface water features, <i>in</i> Geographic Information Science: Proceedings of the 8th International Conference, GIScience, v. 8728, p. 187-203, https://doi.org/10.1007/978-3-319-11593-1_13.","productDescription":"16 p.","startPage":"187","endPage":"203","numberOfPages":"16","ipdsId":"IP-056598","costCenters":[{"id":423,"text":"National Geospatial Program","active":true,"usgs":true}],"links":[{"id":294560,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294559,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/978-3-319-11593-1_13"}],"volume":"8728","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54252e9ee4b0e641df8a6e69","contributors":{"authors":[{"text":"Sinha, Gaurav","contributorId":75075,"corporation":false,"usgs":true,"family":"Sinha","given":"Gaurav","affiliations":[],"preferred":false,"id":497643,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mark, David","contributorId":71906,"corporation":false,"usgs":true,"family":"Mark","given":"David","affiliations":[],"preferred":false,"id":497642,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kolas, Dave","contributorId":12390,"corporation":false,"usgs":true,"family":"Kolas","given":"Dave","email":"","affiliations":[],"preferred":false,"id":497640,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Varanka, Dalia","contributorId":99654,"corporation":false,"usgs":true,"family":"Varanka","given":"Dalia","affiliations":[],"preferred":false,"id":497647,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Romero, Boleslo E.","contributorId":79414,"corporation":false,"usgs":true,"family":"Romero","given":"Boleslo","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":497644,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Feng, Chen-Chieh","contributorId":83854,"corporation":false,"usgs":true,"family":"Feng","given":"Chen-Chieh","email":"","affiliations":[],"preferred":false,"id":497645,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Usery, E.

Initially, the river water that was diverted through these crevasse channels physically removed significant marsh areas within the study area. These initial direct impacts were succeeded by several decades of larger regional loss patterns driven by subsidence and other episodic events (e.g, hurricanes and floods), and recent localized land gains. These increases in land area are potentially the long-term results of the Fort St. Philip crevasses, and the short-term impacts of delta management activities.

Elk were critically important to the Lewis and Clark expedition in providing food and hides that sustained the expedition during the winter of 1805-06 and supplied them for their return east during 1806. Today, elk remain a key component of interpreting the Lewis and Clark story to over 200,000 park visitors each year at the Fort Clatsop visitor center.</p>\n<br>\n<p>In 2008, the US Geological Survey (USGS) began collaborating with Lewis and Clark NHP and \nthe NPS North Coast and Cascades Network to develop a protocol for monitoring long-term \nchanges in the magnitude and spatial patterns of elk use within and adjacent to Lewis and Clark \nNHP (Griffin et al. 2011). Specific objectives of the monitoring program were to measure trends \nin (1) relative use of the Fort Clatsop unit by elk during winter; (2) the proportion of areas where \nelk sign is present in the Fort Clatsop unit in winter; and (3) the frequency of elk sightings from \nroads in and around the Fort Clatsop unit. This report synthesizes the results of the first four \nyears of monitoring elk distribution and use in Lewis and Clark NHP from 2008-2012. We also \npresent data from FY2012 (Appendix 1), in lieu of an annual report for that year.</p>\n<br>\n<p>We used fecal pellet group surveys as the cornerstone for monitoring trends in both relative use \nof the Fort Clatsop Unit by elk and the proportion of areas where elk sign was present at the end \nof winter. We estimated pellet group density based on data collected from a network of fecal \npellet plots distributed systematically throughout the unit. We developed a double observer \nsampling scheme that enabled us to estimate detection biases and improve the accuracy of pellet \ngroup density estimates. We computed the estimated detection probability for any pellet group \nobserved; this probability was a function of the pellet group size and stage of decay, as well as \nlighting and vegetation conditions, and the number of observers (one or two) searching for \npellets in that subplot. We then used these estimated detection probabilities to adjust the raw \ncounts of the detected pellet groups to account for groups that likely went undetected under \nsimilar pellet and environmental conditions (each observed pellet group was weighted by the \ninverse of its estimated detection probability). We also used results from the late winter fecal \npellet surveys to quantify the proportion of areas where elk pellets occurred (PAO), which was \nbased on the presence of fecal pellet groups and estimation of detection biases (i.e., accounting \nfor pellet groups that likely went undetected by both observers). In this synthesis, we report \ntemporal trends in both pellet group density and PAO from 2008-2012, based on weighted linear \nregression analyses as well as spatial variation of pellet group densities over time.</p> \n<br>\n<p>We completed late winter fecal pellet surveys at 61-66 plots annually, depending on yearly \nvariation in access. We cleared fecal pellets at survey points in late October / early November \neach year and returned in late February / early March to count pellet groups left by elk over the \nwinter. The estimated probability that a pellet group was detected by any one observer during \nlate winter was affected most by the pellet group size and was less affected by decay class and \nlighting conditions. Per-observer detection probabilities ranged from as low as ~10-15% for \nsingle pellets to ~85-90% for pellet groups with 50 pellets. Average pellet group density in the \nFort Clatsop unit ranged annually from 0.58 (+/- 1.43 standard error [SE]) to 0.93 (+/- 2.25 SE) \npellet groups per 3-m radius subplot. Pellet group density declined over time, at approximately 8.8% per year (+/- 2.5% SE), but that slope was not statistically distinguishable from zero (2-\ntailed P=0.16). Following correction for detection biases, the proportion of surveyed points used \nby elk (i.e., PAO) ranged from 0.44 (+/- 0.07 SE) to 0.53 (+/- 0.07 SE) during the 4 winters. The \nestimated proportion of areas where elk pellets occurred (PAO) declined at a rate of 2.6% per \nyear (+/- 1.2% per year SE), but that trend also was not statistically distinguishable from zero (2-\ntailed P=0.17). Statistical significance of a measure’s trend depends on both the magnitude (i.e., \nslope) of the observed trend and the number of years the trend continues in the same increasing \nor decreasing direction. Through simulation modeling we determined how many additional years \nof surveys would be required to reveal a statistically significant trend, based on the same trends \nin pellet group density and PAO, and associated variation, observed from 2009-2012. Assuming \nthe same trends persist in the future, simulations indicated that there is a 70% probability that a \nstatistically significant trend would be detected after two more years of conducting pellet group \nsurveys.</p> \n<br>\n<p>Relative use by elk during winter, as indexed by elk pellet group density, was generally greatest \nin the southeast region of the Fort Clatsop unit in or near the large freshwater marsh at the mouth \nof Colewort Creek and adjacent upland areas. Pellet group density was also higher than average \nin the north-central forested area, not far from a privately-owned pasture north of the park \nboundary. This spatial pattern in pellet group densities across the Fort Clatsop unit was \nconsistent across all four years, although specific pellet group densities varied from year to year. \nPellet group density declined significantly over time at two points in the southeast of the Fort \nClatsop unit, even though pellet group density at those points remained higher than the unit \naverage. Pellet group density increased significantly over time at one point in the north-central \nregion, and at one point in the south-central region of the unit, indicating a slight shift in the \ndistribution of elk use within the Fort Clatsop Unit over the four years.</p>\n<br>\n<p>As an index of visitors’ opportunities to see elk in and around the Fort Clatsop Unit, we \nconducted replicated roadside elk surveys 3-5 times monthly during February, April, June, \nAugust, October and December 2008-2012. During each morning of survey, we searched for elk \nalong four routes that totaled 32 km. We examined bimonthly trends in the numbers of elk \ngroups seen, the total number of elk seen, and the observed composition ratios for those six \nmonths of the year. The average number of elk groups seen per survey ranged from 0.75 (+/- \n0.32 SE) during February to a peak of 1.95 (+/- 0.36 SE) during June. Despite this seasonal \nvariation in numbers of elk groups seen, the average total number of elk seen per morning was \nless variable. The average ratios of antlered elk to antlerless adult elk (i.e., bulls:cows) and \ncalves to antlerless adult elk (i.e. calves:cows) varied seasonally, with the highest of both \naverage ratios observed in August. We detected no significant trends in the average number of \nelk groups and total numbers of elk seen per survey from 2008-2012. Similarly, ratios of calves \nand antlered elk per antlerless elk did not differ over time.</p> \n<br>\n<p>Elk groups were frequently seen from January to August in the southeast region of the Fort \nClatsop unit, in the vicinity of Colewort Creek. Outside of NPS lands, we observed elk most \nfrequently in open areas near the Astoria regional airport, in the pastures and forests immediately \nnorth of the Fort Clatsop unit and, prior to the construction of a residential development, in a \npasture northwest of the Fort Clatsop unit.</p>\n<br>\n<p> Elk monitoring at Lewis and Clark NHP is still in its initial years and additional monitoring will \nbe required to verify trends that appear to be emerging. For example, the initial monitoring \nsuggested incipient declining trends in both pellet group density and proportion of plots with \npellets present, as well as, potentially, a small shift in elk distribution away from a new trail that \nwas recently constructed in the southeast portion of the Fort Clatsop unit. Continued monitoring \nwill aid in determining whether this local change in distribution persists (or, alternatively, \nresulted from short-term random variation), and whether there will be any positive or negative \neffect in the northern portion of the unit where a new trail has been constructed. High variability \nin road counts prevented our ability to find any clear trend in numbers or composition of elk \nobserved in and near Fort Clatsop, but changes in the patterns of observations of elk from \nroadways suggest that residential development outside the park has reduced the available habitat \nfor elk in some of the areas surveyed, and may have affected spatial use patterns of elk adjacent \nto some areas of the park. In addition to monitoring future effects of land use changes outside the \npark, continued monitoring may also prove useful for assessing elk responses to natural \nsuccession in forests disturbed by windthrow in December 2007 and to NPS vegetation \nmanagement activities such as variable density thinning in the forest, trail development, and \nrestoration at Otter Point tidal area and Colewort Creek Slough.</p>","language":"English","publisher":"National Park Service","usgsCitation":"Griffin, P., Jenkins, K.J., Cole, C., Clatterbuck, C., Boetsch, J., and Beirne, K., 2014, Elk monitoring in Lewis and Clark National Historical Park: 2008-2012 synthesis report: Natural Resource Technical Report NPS/NCCN/NRTR--2014/837, xii, 56 p.","productDescription":"xii, 56 p.","numberOfPages":"72","temporalStart":"2008-01-01","temporalEnd":"2012-12-31","ipdsId":"IP-053359","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":286057,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281885,"type":{"id":15,"text":"Index Page"},"url":"https://irma.nps.gov/App/Reference/Profile/2206594"}],"country":"United States","state":"Oregon;Washington","otherGeospatial":"Lewis And Clark National Historical Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.1,45.9 ], [ -124.1,46.3 ], [ -123.8,46.3 ], [ -123.8,45.9 ], [ -124.1,45.9 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53559432e4b0120853e8bf5d","contributors":{"authors":[{"text":"Griffin, Paul C.","contributorId":7802,"corporation":false,"usgs":true,"family":"Griffin","given":"Paul C.","affiliations":[],"preferred":false,"id":489768,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jenkins, Kurt J. 0000-0003-1415-6607 kurt_jenkins@usgs.gov","orcid":"https://orcid.org/0000-0003-1415-6607","contributorId":3415,"corporation":false,"usgs":true,"family":"Jenkins","given":"Kurt","email":"kurt_jenkins@usgs.gov","middleInitial":"J.","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true},{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":true,"id":489767,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cole, Carla","contributorId":44809,"corporation":false,"usgs":true,"family":"Cole","given":"Carla","email":"","affiliations":[],"preferred":false,"id":489769,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Clatterbuck, Chris","contributorId":53697,"corporation":false,"usgs":true,"family":"Clatterbuck","given":"Chris","email":"","affiliations":[],"preferred":false,"id":489770,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Boetsch, John","contributorId":57766,"corporation":false,"usgs":true,"family":"Boetsch","given":"John","affiliations":[],"preferred":false,"id":489771,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Beirne, Katherine","contributorId":58754,"corporation":false,"usgs":true,"family":"Beirne","given":"Katherine","affiliations":[],"preferred":false,"id":489772,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Urbanized estuaries are critical wintering and stopover areas for many declining sea ducks in North America; however, conservation measures within estuaries are difficult to establish given lack of knowledge about habitat use by these species and the variety of competing human interests. We applied hierarchical modeling to evaluate resource selection of sea ducks (surf scoters, Melanitta perspicillata) wintering in San Francisco Bay, California, USA, a large and highly urbanized estuary. We also examined their distribution, home range, and movements with respect to key habitat features and regions within the estuary. Herring roe was the strongest predictor of bird locations; however, eelgrass, water depth and salinity were also highly-ranked, with sea ducks using deeper areas of higher salinity associated with herring roe and eelgrass presence during mid-winter. Sea ducks were also strongly associated with ferry routes, suggesting these areas may contain resources that are too important to avoid and emphasizing the need to better understand water traffic effects. Movements and home range size differed between males and females in early winter but became more similar in late winter. Birds traveled farther and used several sub-bays in early winter compared to mid-winter when herring roe availability peaked in the Central Bay. Our findings identified key environmental variables, highlighted core use areas, and documented critical periods for consideration when developing conservation plans for sea ducks in urbanized estuaries.","language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2013.10.021","usgsCitation":"De La Cruz, S.E., Eadie, J.M., Miles, A.K., Yee, J., Spragens, K., Palm, E., and Takekawa, J.Y., 2014, Resource selection and space use by sea ducks during the non-breeding season: Implications for habitat conservation planning in urbanized estuaries: Biological Conservation, v. 169, p. 68-78, https://doi.org/10.1016/j.biocon.2013.10.021.","productDescription":"11 p.","startPage":"68","endPage":"78","numberOfPages":"11","ipdsId":"IP-028582","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":293842,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.5228,37.4452 ], [ -122.5228,38.1442 ], [ -122.0369,38.1442 ], [ -122.0369,37.4452 ], [ -122.5228,37.4452 ] ] ] } } ] }","volume":"169","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54140b26e4b082fed288b963","contributors":{"authors":[{"text":"De La Cruz, Susan E.

The worst of these were generated by local submarine landslides induced by the earthquake. These caused high runups, engulfing several coastal towns in Prince William Sound. In this paper, we study one of these cases in detail, the Port Valdez submarine landslide and tsunami. We combine eyewitness reports, preserved film, and careful posttsunami surveys with new geophysical data to inform numerical models for landslide tsunami generation. We review the series of events as recorded at Valdez old town and then determine the corresponding subsurface events that led to the tsunami. We build digital elevation models of part of the pretsunami and posttsunami fjord‐head delta. Comparing them reveals a ~1500 m long region that receded 150 m to the east, which we interpret as the primary delta landslide source. Multibeam imagery and high‐resolution seismic reflection data identify a ~400 m wide chute with hummocky deposits at its terminus, which may define the primary slide path. Using these elements we run hydrodynamic models of the landslide‐driven tsunamis that match observations of current direction, maximum inundation, and wave height at Valdez old town.

Bulk and microfocused EXAFS spectra of Zn in the biogenic Mn oxide coating are indicative of Zn forming triple-corner-sharing inner-sphere complexes over octahedral vacancies in the Mn oxide sheet structure. Zn desorbed in response to the decrease in pH in batch experiments and resulted in near-equal dissolved Zn at each pH over a 10-fold range in the solid/solution ratio. The geometry of sorbed Zn was unchanged after 50% desorption at pH 5, indicating that desorption is not controlled by dissolution of secondary Zn phases. In summary, these findings support the idea that Zn attenuation in Pinal Creek is largely controlled by sorption to microbial Mn oxides forming in the streambed during hyporheic exchange. Sorption to biogenic Mn oxides is likely an important process of Zn attenuation in circum-neutral pH reaches of many acid-mine drainage contaminated streams when dissolved Mn is present.","language":"English","publisher":"ACS Publications","doi":"10.1021/es402576f","usgsCitation":"Fuller, C.C., and Bargar, J.R., 2014, Processes of zinc attenuation by biogenic manganese oxides forming in the hyporheic zone of Pinal Creek, Arizona: Environmental Science & Technology, v. 48, no. 4, p. 2165-2172, https://doi.org/10.1021/es402576f.","productDescription":"8 p.","startPage":"2165","endPage":"2172","numberOfPages":"8","ipdsId":"IP-049485","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":473242,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://doi.org/10.1021/es402576f","text":"External Repository"},{"id":282125,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282672,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es402576f"}],"country":"United States","state":"Arizona","otherGeospatial":"Pinal Creek","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.913,33.604 ], [ -110.913,33.615 ], [ -110.906,33.615 ], [ -110.906,33.604 ], [ -110.913,33.604 ] ] ] } } ] }","volume":"48","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd6e33e4b0b29085105a25","contributors":{"authors":[{"text":"Fuller, Christopher C. 0000-0002-2354-8074 ccfuller@usgs.gov","orcid":"https://orcid.org/0000-0002-2354-8074","contributorId":1831,"corporation":false,"usgs":true,"family":"Fuller","given":"Christopher","email":"ccfuller@usgs.gov","middleInitial":"C.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":true,"id":485105,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bargar, John R.","contributorId":14970,"corporation":false,"usgs":true,"family":"Bargar","given":"John","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":485106,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Changes in population size and gene flow are two important processes that can cause populations to deviate from this expected relationship. In this study, we used DNA sequences from six independent loci to examine the influence of these processes on standing genetic diversity in endemic mottled ducks (<i>Anas fulvigula</i>) and geographically widespread mallards (<i>A. platyrhynchos</i>), two species known to hybridize. Mottled ducks have an estimated census size that is about two orders-of-magnitude smaller than that of mallards, yet these two species have similar levels of genetic diversity, especially at nuclear DNA. Coalescent analyses suggest that a population expansion in the mallard at least partly explains this discrepancy, but the mottled duck harbors higher genetic diversity and apparent N e than expected for its census size even after accounting for a population decline. Incorporating gene flow into the model, however, reduced the estimated N<sub>e</sub> of mottled ducks to 33 % of the equilibrium N<sub>e</sub> and yielded an estimated N<sub>e</sub> consistent with census size. We also examined the utility of these loci to distinguish among mallards, mottled ducks, and their hybrids. Most putatively pure individuals were correctly assigned to species, but the power for detecting hybrids was low. Although hybridization with mallards potentially poses a conservation threat to mottled ducks by creating a risk of extinction by hybridization, introgression of mallard alleles has helped maintain high genetic diversity in mottled ducks and might be important for the adaptability and survival of this species.","language":"English","publisher":"Springer","doi":"10.1007/s10592-013-0557-9","usgsCitation":"Peters, J.L., Sonsthagen, S.A., Lavretsky, P., Rezsutek, M., Johnson, W.P., and McCracken, K.G.,

This paper integrates over 350 billion lidar points from 28 disparate datasets into a national-scale database and evaluates if height above ground is an important variable in the context of other nationalscale layers, such as the US Geological Survey National Land Cover Database and the US Environmental Protection Agency ecoregions maps. While the results were not homoscedastic and the available data did not allow for a complete height census in any of the classes, it does appear that where lidar data were used, there were detectable differences in heights among many of these national classification schemes. This study supports the hypothesis that there were real, detectable differences in heights in certain national-scale classification schemes, despite height not being a variable used in any of the classification routines.","language":"English","publisher":"American Society for Photogrammetry and Remote Sensing","doi":"10.14358/PERS.80.1.59","usgsCitation":"Stoker, J.M., Cochrane, M.A., and Roy, D.P., 2014, Integrating disparate lidar data at the national scale to assess the relationships between height above ground, land cover and ecoregions: Photogrammetric Engineering and Remote Sensing, v. 80, no. 1, p. 59-70, https://doi.org/10.14358/PERS.80.1.59.","productDescription":"12 p.","startPage":"59","endPage":"70","numberOfPages":"12","ipdsId":"IP-049075","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":473244,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.14358/pers.80.1.59","text":"Publisher Index Page"},{"id":280754,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd62bbe4b0b290850fe5bf","contributors":{"authors":[{"text":"Stoker, Jason M. 0000-0003-2455-0931 jstoker@usgs.gov","orcid":"https://orcid.org/0000-0003-2455-0931","contributorId":3021,"corporation":false,"usgs":true,"family":"Stoker","given":"Jason","email":"jstoker@usgs.gov","middleInitial":"M.","affiliations":[{"id":423,"text":"National Geospatial Program","active":true,"usgs":true},{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":481852,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cochrane, Mark A.","contributorId":20884,"corporation":false,"usgs":false,"family":"Cochrane","given":"Mark","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":481850,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Roy, David P.","contributorId":71083,"corporation":false,"usgs":true,"family":"Roy","given":"David","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":481851,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The American Oystercatcher (<i>Haematopus palliatus</i>) is listed as a \"Species of High Concern'' by the U. S. Shorebird Conservation Plan and is declining in the southern portion of its U. S. breeding range, where ~ 50% of breeding oystercatchers nest on shell substrate instead of beachfront habitat. We measured daily survival rates during incubation and chick rearing in shell rake habitats over five breeding seasons in the Cape Romain region of South Carolina, USA. Of 354 nesting attempts monitored, 16.1% hatched at least one egg. During incubation, daily survival rate was 0.938, corresponding to 22.8% success to hatching (nest success). For broods, daily survival was 0.991, or 74.0% success from hatching to fledging. Productivity in the Cape Romain region is primarily being lost during the incubation phase, when nests are exposed to overwash and predation. Mobile chicks may, however, be able to avoid flood events or predators by relocating to higher or more protected portions of a shell rake. Based on comparative data for American Oystercatchers from elsewhere in their range, it does not appear that shell rakes in the Cape Romain region are inferior breeding habitat. Our data suggest that conservation actions targeting nest and chick loss from flooding and predation have the greatest opportunity to enhance reproductive success in this core breeding area, and that an assessment of the availability, structure, avian use, and protection status of shell rakes is warranted.</p>","language":"English","publisher":"Cooper Ornithological Club","publisherLocation":"Santa Clara, CA","doi":"10.1650/CONDOR-14-35.1","collaboration":"National Fish and Wildlife Foundation; South Carolina State Wildlife Grants Program; Cape Romain National Wildlife Refuge; U.S. Fish and Wildlife Service, U.

Rhynchelmis (Sutroa) klamathensis Fend n. sp. is described from open water benthic habitats in Upper Klamath Lake, Oregon, USA. It resembles other R. (Sutroa) species in the paired spermathecal diverticula, the spermathecal and penial bulbs, the histological structure of the atria, the nonfunctional anterior male funnels, and the arrangement of blood vessels. Rhynchelmis klamathensis differs from all Nearctic Rhynchelmis in lacking a filiform proboscis. The combination of large body size, the elongate spermathecal ducts with paired and usually unbranched diverticula, the highly contorted atria, and the complex male pores with conical penes also distinguish typical R. klamathensis from other Rhynchelmis species. Smaller specimens with otherwise similar morphology, from the Sacramento River Delta, California, are also assigned to this species. Rhynchelmis (Sutroa) diespluviae Fend n. sp. is described from several stream sites, mostly in northern Idaho, USA.

We investigated patterns of sediment accretion in riparian wetlands along the non-tidal through oligohaline portion of two coastal plain rivers in Maryland, U.S.A., and how flow velocity, water level, and suspended sediment concentration (SSC) in the channel may have contributed to those patterns. Sediment accretion was measured over a one year period using artificial marker horizons, channel hydrology was measured over a one month period using acoustic Doppler current profilers, and SSC was predicted from acoustic backscatter. Riparian sediment accretion was lowest at the non-tidal sites (mean and standard deviation = 8 ± 8 mm yr<sup>-1</sup>), highest at the upstream tidal freshwater forested wetlands (TFFW) (33 ± 28 mm yr<sup>-1</sup>), low at the midstream TFFW (12 ± 9 mm yr<sup>-1</sup>), and high at the oligohaline (fresh-to-brackish) marshes (19 ± 8 mm yr<sup>-1</sup>). Channel maximum flood and ebb velocity was 2-fold faster at the oligohaline than tidal freshwater zone on both tidal rivers, corresponding with the differences in in-channel SSC: the oligohaline zone's SSC was more than double the tidal freshwater zone's, and was greater than historical SSC at the non-tidal gages. The tidal wave characteristics differed between rivers, leading to significantly greater in-channel SSC during floodplain inundation in the weakly convergent than the strongly convergent tidal river. Overall sediment accretion was higher in the embayed river likely due to a single storm discharge and associated sedimentation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research F: Earth Surface","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"John Wiley & Sons","publisherLocation":"Hoboken, NJ","doi":"10.1002/2013JF002737","usgsCitation":"Ensign, S., Noe, G., and Hupp, C.R., 2014, Linking channel hydrology with riparian wetland accretion in tidal rivers: Journal of Geophysical Research F: Earth Surface, v. 119, no. 1, p. 28-44, https://doi.org/10.1002/2013JF002737.","productDescription":"17 p.","startPage":"28","endPage":"44","numberOfPages":"17","ipdsId":"IP-049027","costCenters":[{"id":434,"text":"National Research Program","active":false,"usgs":true}],"links":[{"id":473247,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2013jf002737","text":"Publisher Index Page"},{"id":280641,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280640,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/2013JF002737"}],"country":"United States","state":"Maryl","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.5085,36.9279 ], [ -77.5085,39.6015 ], [ -74.8938,39.6015 ], [ -74.8938,36.9279 ], [ -77.5085,36.9279 ] ] ] } } ] }","volume":"119","issue":"1","noUsgsAuthors":false,"publicationDate":"2014-01-14","publicationStatus":"PW","scienceBaseUri":"53cd64b4e4b0b290850ff9b9","contributors":{"authors":[{"text":"Ensign, Scott H.","contributorId":81397,"corporation":false,"usgs":true,"family":"Ensign","given":"Scott H.","affiliations":[],"preferred":false,"id":481029,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Noe, Gregory B.","contributorId":77805,"corporation":false,"usgs":true,"family":"Noe","given":"Gregory B.","affiliations":[],"preferred":false,"id":481028,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hupp, Cliff R. 0000-0003-1853-9197 crhupp@usgs.gov","orcid":"https://orcid.org/0000-0003-1853-9197","contributorId":2344,"corporation":false,"usgs":true,"family":"Hupp","given":"Cliff","email":"crhupp@usgs.gov","middleInitial":"R.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":481027,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Midwater trawling during the surveys as well as target strength provided a measure of species and size composition of the fish community for use in scaling acoustic data and providing species-specific abundance estimates. The 2013 survey consisted of 27 acoustic transects (546 km total) and 31 midwater trawl tows. Mean prey fish biomass was 6.1 kg/ha (relative standard error, RSE = 11%) or 29.6 kilotonnes (kt = 1,000 metric tons), which was similar to the estimate in 2012 (31.1 kt) and 23.5% of the long-term (18 years) mean. The numeric density of the 2013 alewife year class was 6% of the time series average and this year-class contributed 4% of total alewife biomass (5.2 kg/ha, RSE = 12%). Alewife ≥age-1 comprised 96% of alewife biomass. In 2013, alewife comprised 86% of total prey fish biomass, while rainbow smelt and bloater were 4 and 10% of total biomass, respectively. Rainbow smelt biomass in 2013 (0.24 kg/ha, RSE = 17%) was essentially identical to the rainbow smelt biomass in 2012 and was 6% of the long term mean. Bloater biomass in 2013 was 0.6 kg/ha, only half the 2012 biomass, and 6% of the long term mean. Mean density of small bloater in 2013 (29 fish/ha, RSE = 29%) was lower than peak values observed in 2007-2009 and was 23% of the time series mean. In 2013, pelagic prey fish biomass in Lake Michigan was similar to Lake Huron, but pelagic community composition differs in the two lakes, with Lake Huron dominated by bloater.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/70097361","usgsCitation":"Warner, D.M., Farha, S.A., O’Brien, T.P., Ogilvie, L., Claramunt, R., and Hanson, D., 2014, Status of pelagic prey fishes in Lake Michigan, 2013, 12 p., https://doi.org/10.3133/70097361.","productDescription":"12 p.","numberOfPages":"12","ipdsId":"IP-054851","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":287608,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":287607,"type":{"id":11,"text":"Document"},"url":"https://www.in.gov/dnr/fishwild/files/fw-Lake_Michigan_acoustic_report_2014_final.pdf"}],"country":"United States","otherGeospatial":"Lake Michigan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -88.0434,41.6089 ], [ -88.0434,46.1024 ], [ -84.7385,46.1024 ], [ -84.7385,41.6089 ], [ -88.0434,41.6089 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5385b403e4b09e18fc023aae","contributors":{"authors":[{"text":"Warner, David M. 0000-0003-4939-5368 dmwarner@usgs.gov","orcid":"https://orcid.org/0000-0003-4939-5368","contributorId":2986,"corporation":false,"usgs":true,"family":"Warner","given":"David","email":"dmwarner@usgs.gov","middleInitial":"M.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":491537,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Farha, Steven A.","contributorId":79026,"corporation":false,"usgs":true,"family":"Farha","given":"Steven","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":491541,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"O’Brien, Timothy P. 0000-0003-4502-5204 tiobrien@usgs.gov","orcid":"https://orcid.org/0000-0003-4502-5204","contributorId":2662,"corporation":false,"usgs":true,"family":"O’Brien","given":"Timothy","email":"tiobrien@usgs.gov","middleInitial":"P.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":491536,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ogilvie, Lynn","contributorId":60540,"corporation":false,"usgs":true,"family":"Ogilvie","given":"Lynn","affiliations":[],"preferred":false,"id":491540,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Claramunt, Randall M.","contributorId":19047,"corporation":false,"usgs":true,"family":"Claramunt","given":"Randall M.","affiliations":[],"preferred":false,"id":491538,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hanson, Dale","contributorId":43676,"corporation":false,"usgs":true,"family":"Hanson","given":"Dale","affiliations":[],"preferred":false,"id":491539,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We focus on detecting and quantifying Li, Ba, Rb, and Sr in targets analyzed during the first 100 sols, from Bradbury Landing Site to Rocknest. Univariate peak area models and multivariate partial least squares models are presented. Li, detected for the first time directly on Mars, is generally low (<15 ppm). The lack of soil enrichment in Li, which is highly fluid mobile, is consistent with limited influx of subsurface waters contributing to the upper soils. Localized enrichments of up to ~60 ppm Li have been observed in several rocks but the host mineral for Li is unclear. Bathurst_Inlet is a fine-grained bedrock unit in which several analysis locations show a decrease in Li and other alkalis with depth, which may imply that the unit has undergone low-level aqueous alteration that has preferentially drawn the alkalis to the surface. Ba (~1000 ppm) was detected in a buried pebble in the Akaitcho sand ripple and it appears to correlate with Si, Al, Na, and K, indicating a possible feldspathic composition. Rb and Sr are in the conglomerate Link at abundances >100 ppm and >1000 ppm, respectively. These analysis locations tend to have high Si and alkali abundances, consistent with a feldspar composition. Together, these trace element observations provide possible evidence of magma differentiation and aqueous alteration.","language":"English","publisher":"American Geophysical

Since then, blooms have occurred primarily in a 39-km section of Rapid Creek while blooms were rarely observed in other Black Hills streams. In this study, we evaluated factors related to the presence and development of visible colonies of D. geminata in four streams of the Black Hills. At the watershed scale, stream gradient was negatively associated with the occurrence of D. geminata whereas stream width was positively related to D. geminata presence. At the stream scale, D. geminata coverage was inversely related to canopy coverage and iron concentration. At the local scale, shading by bridges virtually eliminated growth of D. geminata colonies under bridges. At all three scales, proxy measures of light such as stream width, canopy coverage, and bridge shading revealed that light availability was an important factor influencing the presence and coverage of D. geminata colonies. In general, streams that had relatively wide stream reaches (mean = 9.9 m), shallow gradients (mean = 0.22%), and little canopy cover (mean = 13%) were associated with D. geminata blooms. In addition, iron concentrations in streams with D. geminata colonies were lower than in streams without blooms.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10750-013-1654-y","usgsCitation":"James, D.A., Mosel, K., and Chipps, S.R., 2014, The influence of light, stream gradient, and iron on <i>Didymosphenia geminata</i> bloom development in the Black Hills, South Dakota: Hydrobiologia, v. 721, no. 1, p. 117-127, https://doi.org/10.1007/s10750-013-1654-y.","productDescription":"11 p.","startPage":"117","endPage":"127","numberOfPages":"11","ipdsId":"IP-049928","costCenters":[{"id":561,"text":"South Dakota Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":281104,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281103,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-013-1654-y"}],"country":"United States","state":"South Dakota","otherGeospatial":"Black Hills","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -104.05,43.81 ], [ -104.05,44.68 ], [ -102.91,44.68 ], [ -102.91,43.81 ], [ -104.05,43.81 ] ] ] } } ] }","volume":"721","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-08-17","publicationStatus":"PW","scienceBaseUri":"53cd7817e4b0b2908510becc","contributors":{"authors":[{"text":"James, Daniel A.","contributorId":41737,"corporation":false,"usgs":true,"family":"James","given":"Daniel","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":486341,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mosel, Kyle","contributorId":30135,"corporation":false,"usgs":true,"family":"Mosel","given":"Kyle","affiliations":[],"preferred":false,"id":486340,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chipps, Steven R. 0000-0001-6511-7582 steve_chipps@usgs.gov","orcid":"https://orcid.org/0000-0001-6511-7582","contributorId":2243,"corporation":false,"usgs":true,"family":"Chipps","given":"Steven","email":"steve_chipps@usgs.gov","middleInitial":"R.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":486339,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
