Some of the highest suspended-sediment concentrations occur on Piedmont streams, including Difficult Run, a tributary of the Potomac River draining urban and suburban parts of northern Virginia. Accurate information on catchment level sediment budgets is rare and difficult to determine. Further, the sediment trapping portion of sediment budget represents an important ecosystem service that profoundly affects downstream water quality. Our objectives, with special reference to human alterations to the landscape, include the documentation and estimation of floodplain sediment trapping (present and historic) and bank erosion along an urbanized Piedmont stream, the construction of a preliminary sediment balance, and the estimation of legacy sediment and recent development impacts. We used white feldspar markers to measure floodplain sedimentation rates and steel pins to measure erosion rates on floodplains and banks, respectively. Additional data were collected for/from legacy sediment thickness and characteristics, mill pond impacts, stream gaging station records, topographic surveying, and sediment density, texture, and organic content. Data were analyzed using GIS and various statistical programs. Results are interpreted relative to stream equilibrium affected by both post-colonial bottomland sedimentation (legacy) and modern watershed hardening associated with urbanization. Six floodplain/channel sites, from high to low in the watershed, were selected for intensive study. Bank erosion ranges from 0 to 470 kg/m/y and floodplain sedimentation ranges from 18 to 1369 kg/m/y (m refers to meters of stream reach). Upstream reaches are net erosional, while downstream reaches have a distinctly net depositional flux providing a watershed sediment balance of 2184 kg/m/y trapped within the system. The amounts of both deposition and erosion are large and suggest nonequilibrium channel conditions. Both peak discharge and number of peaks above base have substantially increased since the mid-1960s when urbanization of the watershed began. Deposition patterns are most closely correlated with channel gradient, sinuosity, and channel width/floodplain width for recent and historic periods. The substantial amounts of fine grained sediment deposited on the floodplain over the past two centuries or so do not appear to be closely related to historic mill pond presence or location. The floodplain continues to provide the critical ecosystem service of sediment trapping in the face of multiple human alterations. Trends in sediment deposition/erosion may react rapidly to land use practices within the watershed and offer a valuable barometer of the effects of management actions.","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.geomorph.2012.10.007","usgsCitation":"Hupp, C.R., Noe, G., Schenk, E.R., and Benthem, A.J., 2012, Recent and historic sediment dynamics along Difficult Run, a suburban Virginia Piedmont stream: Geomorphology, v. 180-181, 14 p., https://doi.org/10.1016/j.geomorph.2012.10.007.","productDescription":"14 p.","numberOfPages":"14","ipdsId":"IP-039432","costCenters":[],"links":[{"id":268541,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":265421,"rank":1,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2012.10.007"}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.293804,38.943012 ], [ -77.293804,38.962448 ], [ -77.287886,38.962448 ], [ -77.287886,38.943012 ], [ -77.293804,38.943012 ] ] ] } } ] }","volume":"180-181","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51308a98e4b04c194073ae37","contributors":{"authors":[{"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":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":471561,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Noe, Gregory B. 0000-0002-6661-2646 gnoe@usgs.gov","orcid":"https://orcid.org/0000-0002-6661-2646","contributorId":2332,"corporation":false,"usgs":true,"family":"Noe","given":"Gregory","email":"gnoe@usgs.gov","middleInitial":"B.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":false,"id":471560,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schenk, Edward R. 0000-0001-6886-5754 eschenk@usgs.gov","orcid":"https://orcid.org/0000-0001-6886-5754","contributorId":2183,"corporation":false,"usgs":true,"family":"Schenk","given":"Edward","email":"eschenk@usgs.gov","middleInitial":"R.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":471559,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Benthem, Adam J. 0000-0003-2372-0281 abenthem@usgs.gov","orcid":"https://orcid.org/0000-0003-2372-0281","contributorId":2740,"corporation":false,"usgs":true,"family":"Benthem","given":"Adam","email":"abenthem@usgs.gov","middleInitial":"J.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":471562,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Beryllium deposits of this type can form where hydrothermal fluids interact with fluorine and lithophile-element (uranium, thorium, rubidium, lithium, beryllium, cesium, tantalum, rare earth elements, and tin) enriched volcanic rocks that contain a highly reactive lithic component, such as carbonate clasts. Volcanic and hypabyssal high-silica biotite-bearing topaz rhyolite constitutes the most well-recognized igneous suite associated with such Be deposits. The exemplar setting is an extensional tectonic environment, such as that characterized by the Basin and Range Province, where younger topaz-bearing igneous rock sequences overlie older dolomite, quartzite, shale, and limestone sequences. Mined deposits and related mineralized rocks at Spor Mountain, Utah, make up a unique economic deposit of volcanogenic Be having extensive production and proven and probable reserves. Proven reserves in Utah, as reported by the U.S. Geological Survey National Mineral Information Center, total about 15,900 tons of Be that are present in the mineral bertrandite (Be<sub>4</sub>Si<sub>2</sub>O<sub>7</sub>(OH)<sub>2</sub>). At the type locality for volcanogenic Be, Spor Mountain, the tuffaceous breccias and stratified tuffs that host the Be ore formed as a result of explosive volcanism that brought carbonate and other lithic fragments to the surface through vent structures that cut the underlying dolomitic Paleozoic sedimentary rock sequences. The tuffaceous sediments and lithic clasts are thought to make up phreatomagmatic base surge deposits. Hydrothermal fluids leached Be from volcanic glass in the tuff and redeposited the Be as bertrandite upon reaction of the hydrothermal fluid with carbonate clasts in lithic-rich sections of tuff. The localization of the deposits in tuff above fluorite-mineralized faults in carbonate rocks, together with isotopic evidence for the involvement of magmatic water in an otherwise meteoric water-dominated hydrothermal system, indicate that magmatic volatiles contributed to mineralization. At the type locality, hydrothermal alteration of dolomite clasts formed layered nodules of calcite, opal, fluorite, and bertrandite, the latter occurring finely intergrown with fluorite. Alteration assemblages and elemental enrichments in the tuff and surrounding volcanic rocks include regional diagenetic clays and potassium feldspar and distinctive hydrothermal halos of anomalous fluorine, lithium, molybdenum, niobium, tin, and tantalum, and intense potassium feldspathization with sericite and lithium-smectite in the immediate vicinity of Be ore. Formation of volcanogenic Be deposits is due to the coincidence of multiple factors that include an appropriate Be-bearing source rock, a subjacent pluton that supplied volatiles and heat to drive convection of meteoric groundwater, a depositional site characterized by the intersection of normal faults with permeable tuff below a less permeable cap rock, a fluorine-rich ore fluid that facilitated Be transport (for example, BeF<sub>4</sub><sup>2-</sup> complex), and the existence of a chemical trap that caused fluorite and bertrandite to precipitate at the former site of carbonate lithic clasts in the tuff.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Mineral deposit models for resource assessment (Scientific Investigations Report 2010-5070)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20105070F","usgsCitation":"Foley, N.K., Hofstra, A.H., Lindsey, D.A., Seal, R., Jaskula, B.W., and Piatak, N., 2012, Occurrence model for volcanogenic beryllium deposits: U.S. Geological Survey Scientific Investigations Report 2010-5070, vi, 43 p., https://doi.org/10.3133/sir20105070F.","productDescription":"vi, 43 p.","numberOfPages":"52","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":265312,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2010_5070_F.gif"},{"id":399523,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_98030.htm"},{"id":265310,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2010/5070/f/"},{"id":265311,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2010/5070/f/SIR10-5070F.pdf","text":"Report","size":"11.1 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50eaabf2e4b02dd6076fadb0","contributors":{"authors":[{"text":"Foley, Nora K. 0000-0003-0124-3509 nfoley@usgs.gov","orcid":"https://orcid.org/0000-0003-0124-3509","contributorId":4010,"corporation":false,"usgs":true,"family":"Foley","given":"Nora","email":"nfoley@usgs.gov","middleInitial":"K.","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":471436,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hofstra, Albert H. 0000-0002-2450-1593 ahofstra@usgs.gov","orcid":"https://orcid.org/0000-0002-2450-1593","contributorId":1302,"corporation":false,"usgs":true,"family":"Hofstra","given":"Albert","email":"ahofstra@usgs.gov","middleInitial":"H.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":471434,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lindsey, David A. 0000-0002-9466-0899 dlindsey@usgs.gov","orcid":"https://orcid.org/0000-0002-9466-0899","contributorId":773,"corporation":false,"usgs":true,"family":"Lindsey","given":"David","email":"dlindsey@usgs.gov","middleInitial":"A.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":471433,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Seal, Robert R.

In this study, we demonstrate two approaches to the use of multiple sources of information on a parameter of fundamental interest to ecologists: animal density. The first approach produces estimates simultaneously from two different sources of data. The second approach was developed for situations in which initial data collection and analysis are followed up by subsequent data collection and prior knowledge is updated with new data using a stepwise process. Both approaches are used to estimate density of a rare and elusive predator, the tiger, by combining photographic and fecal DNA spatial capture–recapture data. The model, which combined information, provided the most precise estimate of density (8.5 ± 1.95 tigers/100 km<sup>2</sup> [posterior mean ± SD]) relative to a model that utilized only one data source (photographic, 12.02 ± 3.02 tigers/100 km<sup>2</sup> and fecal DNA, 6.65 ± 2.37 tigers/100 km<sup>2</sup>).

A review of the current literature for luminescence dating of gypsum is compiled here along with original efforts at dating an intact and in-situ bed of selenite gypsum at Salt Basin Playa, New Mexico and Texas. This effort differs from other documented luminescence dating efforts because the gypsum is not powdery or redistributed from its original growth patterns within the playa basin but is instead of a crystalline form. Sixteen ages from eight cores were ultimately produced with seven of the ages coming from rare detrital quartz encased in or with the gypsum crystals while the remaining ages are from the crystalline gypsum. As far as can be ascertained, the quartz was measured separately from the gypsum and no contaminants were noted in any of the aliquots. Some basic and preliminary tests of signal stability were measured and found to be mitigated by lessening of pre-heat protocols. Ages ranged from 8 ka to 10 ka in the shallow cores and 16 ka to 22 ka in the deeper cores. These ages will be useful in determining rates of gypsum growth within a sequence of evaporates which, in turn, will help to better document historic rates of evaporation and thus estimate, with more precision, the corresponding annual evaporation rates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Geochronology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.quageo.2012.02.001","usgsCitation":"Mahan, S., and Kay, J., 2012, Building on previous OSL dating techniques for gypsum: a case study from Salt Basin playa, New Mexico and Texas: Quaternary Geochronology, v. 10, p. 345-352, https://doi.org/10.1016/j.quageo.2012.02.001.","productDescription":"8 p.","startPage":"345","endPage":"352","ipdsId":"IP-034741","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":275604,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275603,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.quageo.2012.02.001"}],"country":"United States","city":"Texas;New Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.05,25.84 ], [ -109.05,37.0 ], [ -93.51,37.0 ], [ -93.51,25.84 ], [ -109.05,25.84 ] ] ] } } ] }","volume":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51f8e060e4b0cecbe8fa9859","contributors":{"authors":[{"text":"Mahan, Shannon 0000-0001-5214-7774","orcid":"https://orcid.org/0000-0001-5214-7774","contributorId":19239,"corporation":false,"usgs":true,"family":"Mahan","given":"Shannon","affiliations":[],"preferred":false,"id":481667,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kay, John","contributorId":108380,"corporation":false,"usgs":true,"family":"Kay","given":"John","email":"","affiliations":[],"preferred":false,"id":481668,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Research has recently shifted from a focus on factors influencing migration to how migration affects nutrient cycling and habitat coupling. Here we evaluate the potential for Daphnia migrations to incorporate metalimnetic productivity in a well-studied northern Wisconsin lake. We use prior studies conducted between 1985 and 1990 and current diel migration data (2008) to compare day and night Daphnia vertical distributions with the depth of the metalimnion (between the thermocline and 1% light depth). Daphnia migrate from a daytime mean residence depth of between about 1.7 and 2.5 m to a nighttime mean residence depth of between 0 and 2.0 m.

The composition of these midlatitude, deep-water deposits is markedly different from northwest-equatorial Pacific (PCZ) crusts, where most studies have been conducted. Crusts and nodules on SR formed in close proximity and some nodule deposits were cemented and overgrown by crusts, forming amalgamated deposits. The deep-water SR crusts are high in Cu, Li, and Th and low in Co, Te, and Tl concentrations compared to PCZ crusts. Thorium concentrations (ppm) are especially striking with a high of 152 (mean 56), compared to PCZ crusts (mean 11). The deep-water SR crusts show a diagenetic chemical signal, but not a diagenetic mineralogy, which together constrain the redox conditions to early oxic diagenesis. Diagenetic input to crusts is rare, but unequivocal in these deep-water crusts. Copper, Ni, and Li are strongly enriched in SR deep-water deposits, but only in layers older than about 3.4 Ma. Diagenetic reactions in the sediment and dissolution of biogenic calcite in the water column are the likely sources of these metals. The highest concentrations of Li are in crust layers that formed near the calcite compensation depth. The onset of Ni, Cu, and Li enrichment in the middle Miocene and cessation at about 3.4 Ma were accompanied by changes in the deep-water environment, especially composition and flow rates of water masses, and location of the carbonate compensation depth.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochemistry, Geophysics, Geosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AGU","doi":"10.1029/2012GC004286","usgsCitation":"Hein, J., Conrad, T., Frank, M., Christl, M., and Sager, W., 2012, Copper-nickel-rich, amalgamated ferromanganese crust-nodule deposits from Shatsky Rise, NW Pacific: Geochemistry, Geophysics, Geosystems, v. 13, no. 10, Q10022, https://doi.org/10.1029/2012GC004286.","productDescription":"Q10022","ipdsId":"IP-041319","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":487193,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"text":"External Repository"},{"id":274879,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274878,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2012GC004286"}],"otherGeospatial":"Shatsky Rise","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 152.0,30.0 ], [ 152.0,44.0 ], [ 168.0,44.0 ], [ 168.0,30.0 ], [ 152.0,30.0 ] ] ] } } ] }","volume":"13","issue":"10","noUsgsAuthors":false,"publicationDate":"2012-10-30","publicationStatus":"PW","scienceBaseUri":"51dfd3e1e4b0d332bf22f372","contributors":{"authors":[{"text":"Hein, J.R. 0000-0002-5321-899X","orcid":"https://orcid.org/0000-0002-5321-899X","contributorId":61429,"corporation":false,"usgs":true,"family":"Hein","given":"J.R.","affiliations":[],"preferred":false,"id":480468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conrad, T.A.","contributorId":21791,"corporation":false,"usgs":true,"family":"Conrad","given":"T.A.","email":"","affiliations":[],"preferred":false,"id":480466,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Frank, M.","contributorId":103396,"corporation":false,"usgs":true,"family":"Frank","given":"M.","email":"","affiliations":[],"preferred":false,"id":480470,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Christl, M.","contributorId":76626,"corporation":false,"usgs":true,"family":"Christl","given":"M.","email":"","affiliations":[],"preferred":false,"id":480469,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sager, W.W.","contributorId":54487,"corporation":false,"usgs":true,"family":"Sager","given":"W.W.","email":"","affiliations":[],"preferred":false,"id":480467,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We review the effects of predation, feline diseases, and the life \nhistory characteristics of feral cats and their prey that have contributed to the \nextirpation and extinction of many insular vertebrate species. The protozoan \n<i>Toxoplasma gondii</i> is a persistent land-based zoonotic pathogen hosted by \ncats that is known to cause mortality in several insular bird species. It also \nenters marine environments in cat feces where it can cause the mortality of \nmarine mammals. Feral cats remain widespread on islands throughout the \nworld and are frequently subsidized in colonies which caretakers often \nassert have little negative effect on native wildlife. However, population \ngenetics, home range, and movement studies all suggest that there are no \nlocations on smaller islands where these cats cannot penetrate within two \ngenerations. While the details of past vertebrate extinctions were rarely \ndocumented during contemporary time, a strong line of evidence is \nemerging that the removal of feral cats from islands can rapidly facilitate the \nrecolonization of extirpated species, particularly seabirds. Islands offer \nunique, mostly self-contained ecosystems in which to conduct controlled \nstudies of the effects of feral cats on wildlife, having implications for \ncontinental systems. The response of terrestrial wildlife such as passerine \nbirds, small mammals, and herptiles still needs more thorough long-term \nmonitoring and documentation after the removal of feral cats.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Vertebrate Pest Conference","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"University of California, Davis","usgsCitation":"Hess, S., and Danner, R.M., 2012, The effects of feral cats on insular wildlife: the Club-Med syndrome, <i>in</i> Proceedings of the Vertebrate Pest Conference, v. 25, p. 76-82.","productDescription":"7 p.","startPage":"76","endPage":"82","numberOfPages":"7","ipdsId":"IP-039153","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":285413,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285412,"type":{"id":15,"text":"Index Page"},"url":"https://nebraskamaps.unl.edu/productcart/pc/viewPrd.asp?idproduct=13044&idcategory=579"}],"volume":"25","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5355959ee4b0120853e8c27d","contributors":{"editors":[{"text":"Timm, R.

In the Laurentian Great Lakes, data from midwater trawls are commonly used for such allocations. However, there are no rules for how much midwater trawling effort is required to adequately describe species and size composition of the pelagic fish communities in these lakes, so the balance between acoustic sampling effort and trawling effort has been unguided. We used midwater trawl data collected between 1986 and 2008 in lakes Michigan and Huron and a variety of analytical techniques to develop guidance for appropriate levels of trawl effort. We used multivariate regression trees and re-sampling techniques to i. identify factors that influence species and size composition of the pelagic fish communities in these lakes, ii. identify stratification schemes for the two lakes, iii. determine if there was a relationship between uncertainty in catch composition and the number of tows made, and iv. predict the number of tows required to reach desired uncertainty targets. We found that depth occupied by fish below the surface was the most influential explanatory variable. Catch composition varied between lakes at depths <38.5 m below the surface, but not at depths ≥38.5 m below the surface. Year, latitude, and bottom depth influenced catch composition in the near-surface waters of Lake Michigan, while only year was important for Lake Huron surface waters. There was an inverse relationship between RSE [relative standard error = 100 × (SE/mean)] and the number of tows made for the proportions of the different size and species groups. We found for the fifth (Lake Huron) and sixth (Lake Michigan) largest lakes in the world, 15–35 tows were adequate to achieve target RSEs (15% and 30%) for ubiquitous species, but rarer species required much higher, and at times, impractical effort levels to reach these targets.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fisheries Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.fishres.2011.11.021","usgsCitation":"Warner, D.M., Claramunt, R., Schaeffer, J.S., Yule, D., Hrabik, T.R., Peintka, B., Rudstam, L.G., Holuszko, J.D., and O’Brien, T.P., 2012, Relationship between mid-water trawling effort and catch composition uncertainty in two large lakes (Huron and Michigan) dominated by alosines, osmerids, and coregonines: Fisheries Research, v. 123-124, p. 62-69, https://doi.org/10.1016/j.fishres.2011.11.021.","productDescription":"8 p.","startPage":"62","endPage":"69","ipdsId":"IP-023624","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":268999,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268998,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.fishres.2011.11.021"}],"otherGeospatial":"Lake Michigan;Lake Huron","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -88.49,41.69 ], [ -88.49,46.35 ], [ -80.54,46.35 ], [ -80.54,41.69 ], [ -88.49,41.69 ] ] ] } } ] }","volume":"123-124","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7028e4b0b29085106e14","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":471028,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Claramunt, Randall M.","contributorId":19047,"corporation":false,"usgs":true,"family":"Claramunt","given":"Randall M.","affiliations":[],"preferred":false,"id":471030,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schaeffer, Jeffrey S.","contributorId":89083,"corporation":false,"usgs":true,"family":"Schaeffer","given":"Jeffrey","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":471033,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Yule, Daniel L.","contributorId":92130,"corporation":false,"usgs":true,"family":"Yule","given":"Daniel L.","affiliations":[],"preferred":false,"id":471034,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hrabik, Tom R.","contributorId":87829,"corporation":false,"usgs":true,"family":"Hrabik","given":"Tom","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":471032,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peintka, Bernie","contributorId":18240,"corporation":false,"usgs":true,"family":"Peintka","given":"Bernie","email":"","affiliations":[],"preferred":false,"id":471029,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rudstam, Lars G.","contributorId":56609,"corporation":false,"usgs":false,"family":"Rudstam","given":"Lars","email":"","middleInitial":"G.","affiliations":[{"id":12722,"text":"Cornell University","active":true,"usgs":false}],"preferred":false,"id":471031,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Holuszko, Jeffrey D.","contributorId":104429,"corporation":false,"usgs":true,"family":"Holuszko","given":"Jeffrey","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":471035,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"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":471027,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Economic analyses have shown that territories of animals are structured by trade-offs between benefits gained from resources and costs of defending them. Intuitively, home ranges should be similarly structured, but trade-offs are difficult to assess because there are no costs of defense, thus economic models of home-range behavior are rare. We present economic models that predict how home ranges can be efficient with respect to spatially distributed resources, discounted for travel costs, under 2 strategies of optimization, resource maximization and area minimization. We show how constraints such as competitors can influence structure of homes ranges through resource depression, ultimately structuring density of animals within a population and their distribution on a landscape. We present simulations based on these models to show how they can be generally predictive of home-range behavior and the mechanisms that structure the spatial distribution of animals. We also show how contiguous home ranges estimated statistically from location data can be misleading for animals that optimize home ranges on landscapes with patchily distributed resources. We conclude with a summary of how we applied our models to nonterritorial black bears (Ursus americanus) living in the mountains of North Carolina, where we found their home ranges were best predicted by an area-minimization strategy constrained by intraspecific competition within a social hierarchy. Economic models can provide strong inference about home-range behavior and the resources that structure home ranges by offering falsifiable, a priori hypotheses that can be tested with field observations.</p>","language":"English","publisher":"American Society of Mammalogists","doi":"10.1644/11-MAMM-S-157.1","usgsCitation":"Mitchell, M.S., and Powell, R.A., 2012, Foraging optimally for home ranges: Journal of Mammalogy, v. 93, no. 4, p. 917-928, https://doi.org/10.1644/11-MAMM-S-157.1.","productDescription":"12 p.","startPage":"917","endPage":"928","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-035484","costCenters":[{"id":399,"text":"Montana Cooperative Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":274079,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274078,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/11-MAMM-S-157.1"}],"volume":"93","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-09-14","publicationStatus":"PW","scienceBaseUri":"51c59e34e4b0c89b8f120e3b","contributors":{"authors":[{"text":"Mitchell, Michael S. 0000-0002-0773-6905 mmitchel@usgs.gov","orcid":"https://orcid.org/0000-0002-0773-6905","contributorId":3716,"corporation":false,"usgs":true,"family":"Mitchell","given":"Michael","email":"mmitchel@usgs.gov","middleInitial":"S.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":356280,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powell, Roger A.","contributorId":9163,"corporation":false,"usgs":true,"family":"Powell","given":"Roger","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":356281,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Fallicambarus fodiens is one of West Virginia&rsquo;s rarest crayfish, while C. thomai is prevalent in most wetlands along both river floodplains.

Based on presence/absence data, forests with tree ages &gt;100 years (&Delta;QAICc&nbsp;= 0) and sites with loam soils (&Delta;QAICc&nbsp;= 1.80) were most likely to harbor F. fodiens populations. For C. thomai, several models were supported owing to model selection uncertainty, but those with the land use covariate had more total model weight (total w i = 0 . 54 ) than all other covariate models. Cambarus thomai rarely occupied industrial/agricultural sites, but were often present in forested and residential sites.

We hypothesized that the distribution of pintails during spring staging was influenced by patterns of land use and expected that the most frequently used areas would have more agricultural habitat than lesser-used areas. We obtained 3031 daily locations from 163 migrant pintails marked with satellite transmitters and identified 524 stopover sites. Based on a fixed kernel home range analysis of stopover utilization distribution (UD), core staging areas (areas within the 50% UD) were identified in northern Honshu and western Hokkaido, and were used by 71% of marked pintails. Core staging areas had a greater proportion of rice fields than peripheral (51–95% UD) and rarely used (outside the 95% UD) staging areas. Stopover sites also contained more rice fields and other agricultural land than were available at regional scales, indicating that pintails selected rice and other agricultural habitats at regional and local scales. Pintails remained at spring staging areas an average of 51 d. Prolonged staging in agricultural habitats of northern Japan was likely necessary for pintails to prepare for transoceanic migration to Arctic nesting areas in eastern Russia.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Field Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1557-9263.2012.00364.x","usgsCitation":"Yamaguchi, N.M., Hupp, J.W., Flint, P.L., Pearce, J.M., Shigeta, Y., Shimada, T., Hiraoka, E.N., and Higuchi, H., 2012, Habitat use and movement patterns of Northern Pintails during spring in northern Japan: the importance of agricultural lands: Journal of Field Ornithology, v. 83, no. 2, p. 141-153, https://doi.org/10.1111/j.1557-9263.2012.00364.x.","productDescription":"13 p.","startPage":"141","endPage":"153","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":271756,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271755,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1557-9263.2012.00364.x"}],"country":"Japan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 122.93,24.0 ], [ 122.93,45.52 ], [ 153.99,45.52 ], [ 153.99,24.0 ], [ 122.93,24.0 ] ] ] } } ] }","volume":"83","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-05-25","publicationStatus":"PW","scienceBaseUri":"51838aeae4b0a21483941ab2","contributors":{"authors":[{"text":"Yamaguchi, Noriyuki M.","contributorId":55308,"corporation":false,"usgs":true,"family":"Yamaguchi","given":"Noriyuki","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":478305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hupp, Jerry W. 0000-0002-6439-3910 jhupp@usgs.gov","orcid":"https://orcid.org/0000-0002-6439-3910","contributorId":127803,"corporation":false,"usgs":true,"family":"Hupp","given":"Jerry","email":"jhupp@usgs.gov","middleInitial":"W.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":478301,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Flint, Paul L. 0000-0002-8758-6993 pflint@usgs.gov","orcid":"https://orcid.org/0000-0002-8758-6993","contributorId":3284,"corporation":false,"usgs":true,"family":"Flint","given":"Paul","email":"pflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":478302,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pearce, John M. 0000-0002-8503-5485 jpearce@usgs.gov","orcid":"https://orcid.org/0000-0002-8503-5485","contributorId":181766,"corporation":false,"usgs":true,"family":"Pearce","given":"John","email":"jpearce@usgs.gov","middleInitial":"M.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":478300,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shigeta, Yusuke","contributorId":9151,"corporation":false,"usgs":true,"family":"Shigeta","given":"Yusuke","email":"","affiliations":[],"preferred":false,"id":478303,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Shimada, Tetsuo","contributorId":52065,"corporation":false,"usgs":true,"family":"Shimada","given":"Tetsuo","email":"","affiliations":[],"preferred":false,"id":478304,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hiraoka, Emiko N.","contributorId":75043,"corporation":false,"usgs":true,"family":"Hiraoka","given":"Emiko","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":478307,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Higuchi, Hiroyoshi","contributorId":69850,"corporation":false,"usgs":true,"family":"Higuchi","given":"Hiroyoshi","email":"","affiliations":[],"preferred":false,"id":478306,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

We test if elevated concentrations of metals in water and sediment are restricted to streams downstream of mines or areas that may discharge mine wastes. We surveyed 198 catchments classified as “historically mined” or “unmined,” and based on mineral-deposit criteria, to determine whether water and sediment quality were influenced by naturally occurring mineralized rock, by historical mining, or by a combination of both. By accounting for different geologic sources of metals to the environment, we were able to distinguish aquatic ecosystems limited by metals derived from natural processes from those due to mining. Elevated concentrations of metals in water and sediment were not restricted to mined catchments; depauperate aquatic communities were found in unmined catchments. The type and intensity of hydrothermal alteration and the mineral deposit type were important determinants of water and sediment quality as well as the aquatic community in both mined and unmined catchments. This study distinguished the effects of different rock types and geologic sources of metals on ecosystems by incorporating basic geologic processes into reference and baseline site selection, resulting in a refined assessment. Our results indicate that biomonitoring studies should account for natural sources of metals in some geologic environments as contributors to the effect of mines on aquatic ecosystems, recognizing that in mining-impacted drainages there may have been high pre-mining background metal concentrations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ESA","doi":"10.1890/11-0806.1","usgsCitation":"Schmidt, T., Clements, W.H., Wanty, R.B., Verplanck, P.L., Church, S.E., San Juan, C.A., Fey, D.L., Rockwell, B.W., DeWitt, E.H., and Klein, T.L., 2012, Geologic processes influence the effects of mining on aquatic ecosystems: Ecological Applications, v. 22, no. 3, p. 870-879, https://doi.org/10.1890/11-0806.1.","productDescription":"10 p.","startPage":"870","endPage":"879","ipdsId":"IP-017393","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":274030,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274029,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/11-0806.1"}],"volume":"22","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51c42460e4b03c77dce65a48","contributors":{"authors":[{"text":"Schmidt, Travis S. 0000-0003-1400-0637 tschmidt@usgs.gov","orcid":"https://orcid.org/0000-0003-1400-0637","contributorId":1300,"corporation":false,"usgs":true,"family":"Schmidt","given":"Travis S.","email":"tschmidt@usgs.gov","affiliations":[{"id":37277,"text":"WMA -

We document two types of light rare-earth element (LREE)-enriched rocks in the Khanneshin carbonatite complex of southern Afghanistan: type 1 concordant seams of khanneshite-(Ce), synchysite-(Ce), and parisite-(Ce) within banded barite-strontianite alvikite, and type 2 igneous dikes of coarse-grained carbonatite, enriched in fluorine or phosphorus, containing idiomorphic crystals of khanneshite-(Ce) or carbocernaite. Type 1 mineralized barite-strontianite alvikite averages 22.25 wt % BaO, 4.27 wt % SrO, and 3.25 wt % ∑ LREE<sub>2</sub>O<sub>3</sub> (sum of La, Ce, Pr, and Nd oxides).

A magmatic origin is clearly indicated for the type 2 LREE-enriched dikes, and type 1 LREE mineralization probably formed in the presence of LREE-rich hydrothermal fluid. Both types of LREE mineralization may be penecontemporaneous, having formed in a carbonate-rich magma in the marginal zone of the central vent, highly charged with volatile constituents (i.e., CO<sub>2</sub>, F, P<sub>2</sub>O<sub>5</sub>), and strongly enriched in Ba, Sr, and the LREE. Based on several assumptions, and employing simple geometry for the zone of LREE enrichment, we estimate that at least 1.29 Mt (million metric tonnes) of LREE2O3 is present in this part of the Khanneshin carbonatite complex.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Economic Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society of Economic Geologists","publisherLocation":"Littleton, CO","doi":"10.2113/econgeo.107.2.197","usgsCitation":"Tucker, R.D., Belkin, H.E., Schulz, K.J., Peters, S., Horton, F., Buttleman, K., and Scott, E.R., 2012, A major light rare-earth element (LREE) resource in the Khanneshin carbonatite complex, southern Afghanistan: Economic Geology, v. 107, no. 2, p. 197-208, https://doi.org/10.2113/econgeo.107.2.197.","productDescription":"12 p.","startPage":"197","endPage":"208","ipdsId":"IP-034879","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":270566,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":270565,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2113/econgeo.107.2.197"}],"country":"Afghanistan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 60.52,29.38 ], [ 60.52,38.49 ], [ 74.89,38.49 ], [ 74.89,29.38 ], [ 60.52,29.38 ] ] ] } } ] }","volume":"107","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-02-15","publicationStatus":"PW","scienceBaseUri":"515ea0e4e4b088aa22580942","contributors":{"authors":[{"text":"Tucker, Robert D. 0000-0001-8463-4358 rtucker@usgs.gov","orcid":"https://orcid.org/0000-0001-8463-4358","contributorId":2007,"corporation":false,"usgs":true,"family":"Tucker","given":"Robert","email":"rtucker@usgs.gov","middleInitial":"D.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":475090,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Belkin, Harvey E. 0000-0001-7879-6529 hbelkin@usgs.gov","orcid":"https://orcid.org/0000-0001-7879-6529","contributorId":581,"corporation":false,"usgs":true,"family":"Belkin","given":"Harvey","email":"hbelkin@usgs.gov","middleInitial":"E.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":475089,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schulz, Klaus J. 0000-0003-2967-4765 kschulz@usgs.gov","orcid":"https://orcid.org/0000-0003-2967-4765","contributorId":2438,"corporation":false,"usgs":true,"family":"Schulz","given":"Klaus","email":"kschulz@usgs.gov","middleInitial":"J.","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":475091,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Peters, Stephen G. speters@usgs.gov","contributorId":2793,"corporation":false,"usgs":true,"family":"Peters","given":"Stephen G.","email":"speters@usgs.gov","affiliations":[{"id":596,"text":"U.S. Geological Survey National Center","active":false,"usgs":true}],"preferred":false,"id":475092,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Horton, Forrest","contributorId":17110,"corporation":false,"usgs":true,"family":"Horton","given":"Forrest","affiliations":[],"preferred":false,"id":475093,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Buttleman, Kim","contributorId":68619,"corporation":false,"usgs":true,"family":"Buttleman","given":"Kim","email":"","affiliations":[],"preferred":false,"id":475095,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Scott, Emily R.","contributorId":68188,"corporation":false,"usgs":true,"family":"Scott","given":"Emily","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":475094,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

However, thousands of sand dunes spread across 12,000 km<sup>2</sup> in eastern upper Michigan (EUM), more than 500 km east of the present forest-prairie ecotone, present a challenge to such models. We use 65 optically stimulated luminescence (OSL) ages on quartz sand deposited in silt caps (n = 8) and dunes (n = 57) to document eolian activity in EUM. Dune building was widespread ca. 10–8 ka, indicating a sharp, sustained decline in forest cover during that period. This decline was roughly coincident with hydrologic closure of the upper Great Lakes, but temporally inconsistent with most pollen-based models that imply canopy closure throughout the Holocene. Early Holocene forest openings are rarely recognized in pollen sums from EUM because faint signatures of non-arboreal pollen are largely obscured by abundant and highly mobile pine pollen. Early Holocene spikes in nonarboreal pollen are recorded in cores from small ponds, but suggest only a modest extent of forest openings. OSL dating of dune emplacement provides a direct, spatially explicit archive of greatly diminished forest cover during a very dry climate in eastern midcontinent North America ca. 10–8 ka.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"GSA","doi":"10.1130/G32937.1","usgsCitation":"Loope, W.L., Loope, H.M., Goble, R.J., Fisher, T.G., Lytle, D.E., Legg, R.J., Wysocki, D., Hanson, P.R., and Young, A., 2012, Drought drove forest decline and dune building in eastern upper Michigan, USA, as the upper Great Lakes became closed basins: Geology, v. 40, no. 4, p. 315-318, https://doi.org/10.1130/G32937.1.","productDescription":"4 p.","startPage":"315","endPage":"318","ipdsId":"IP-028146","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":271774,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271773,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G32937.1"}],"otherGeospatial":"North America","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 177.1,5.6 ], [ 177.1,85.4 ], [ -4.0,85.4 ], [ -4.0,5.6 ], [ 177.1,5.6 ] ] ] } } ] }","volume":"40","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-02-28","publicationStatus":"PW","scienceBaseUri":"51838ae8e4b0a21483941a9d","contributors":{"authors":[{"text":"Loope, Walter L. wloope@usgs.gov","contributorId":4616,"corporation":false,"usgs":true,"family":"Loope","given":"Walter","email":"wloope@usgs.gov","middleInitial":"L.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":474439,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Loope, Henry M.","contributorId":79381,"corporation":false,"usgs":true,"family":"Loope","given":"Henry","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":474446,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goble, Ronald J.","contributorId":61319,"corporation":false,"usgs":true,"family":"Goble","given":"Ronald","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":474444,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fisher, Timothy G.","contributorId":45659,"corporation":false,"usgs":true,"family":"Fisher","given":"Timothy","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":474443,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lytle, David E. dlytle@usgs.gov","contributorId":343,"corporation":false,"usgs":true,"family":"Lytle","given":"David","email":"dlytle@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":474438,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Legg, Robert J.","contributorId":30527,"corporation":false,"usgs":true,"family":"Legg","given":"Robert","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":474441,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Wysocki, Douglas A.","contributorId":61320,"corporation":false,"usgs":true,"family":"Wysocki","given":"Douglas A.","affiliations":[],"preferred":false,"id":474445,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hanson, Paul R.","contributorId":35214,"corporation":false,"usgs":true,"family":"Hanson","given":"Paul","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":474442,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Young, Aaron R.","contributorId":12353,"corporation":false,"usgs":true,"family":"Young","given":"Aaron R.","affiliations":[],"preferred":false,"id":474440,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

The origin of strata-hosted Co-Cu ± Au mineralization at Blackbird has been a matter of controversy for decades. In order to differentiate among possible genetic models for the deposits, including various combinations of volcanic, sedimentary, magmatic, and metamorphic processes, we used U-Pb geochronology of xenotime, monazite, and zircon to establish time constraints for ore formation. New age data reported here were obtained using sensitive high resolution ion microprobe (SHRIMP) microanalysis of (1) detrital zircons from a sample of Mesoproterozoic siliciclastic metasedimentary country rock in the Blackbird district, (2) igneous zircons from Mesoproterozoic intrusions, and (3) xenotime and monazite from the Merle and Sunshine prospects at Blackbird.</p><p>Detrital zircon from metasandstone of the biotite phyllite-schist unit has ages mostly in the range of 1900 to 1600 Ma, plus a few Neoarchean and Paleoproterozoic grains. Age data for the six youngest grains form a coherent group at 1409 ± 10 Ma, regarded as the maximum age of deposition of metasedimentary country rocks of the central structural domain. Igneous zircons from nine samples of megacrystic granite, granite augen gneiss, and granodiorite augen gneiss that crop out north and east of the Blackbird district yield ages between 1383 ± 4 and 1359 ± 7 Ma. Emplacement of the Big Deer Creek megacrystic granite (1377 ± 4 Ma), structurally juxtaposed with host rocks in the Late Cretaceous ca. 5 km north of Blackbird, may have been involved in initial deposition of rare earth elements (REE) minerals and, possibly, sulfides.</p><p>In situ SHRIMP ages of xenotime and monazite in Co-rich samples from the Merle and Sunshine prospects, plus backscattered electron imagery and SHRIMP analyses of trace elements, indicate a complex sequence of Mesoproterozoic and Cretaceous events. On the basis of textural relationships observed in thin section, xeno-time and cobaltite formed during multiple episodes. The oldest age for xenotime (1370 ± 4 Ma), determined on oscillatory-zoned cores, may date the time of initial cobaltite formation, and provides a minimum age for the host metasedimentary rocks. Additional Proterozoic xenotime growth events occurred at 1315 to 1270 Ma and ca. 1050 Ma. Other xenotime grains and rims grew in conjunction with cobaltite during Cretaceous metamorphism.

The sites were established in response to an Environmental Impact Statement that addressed the use of personal watercraft on Lake Powell. The use of personal watercraft can potentially introduce hydrocarbons and other contaminants and are of concern to the health of visitors and aquatic habitats of these environments.

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 2012 survey consisted of 26 acoustic transects (576 km total) and 31 midwater tows. Mean total prey fish biomass was 6.4 kg/ha (relative standard error, RSE = 15%) or 31 kilotonnes (kt = 1,000 metric tons), which was 1.5 times the estimate for 2011 and 22% of the long-term mean. The increase from 2011 resulted from increased biomass of age-0 alewife, age-1 or older alewife, and large bloater. The abundance of the 2012 alewife year class was similar to the average, and this year-class contributed 35% of total alewife biomass (4.9 kg/ha, RSE = 17%), while the 2010 alewife year-class contributed 58%. The 2010 year class made up 89% of age-1 or older alewife biomass. In 2012, alewife comprised 77% of total prey fish biomass, while rainbow smelt and bloater were 4 and 19% of total biomass, respectively. Rainbow smelt biomass in 2012 (0.25 kg/ha, RSE = 17%) was 40% of the rainbow smelt biomass in 2011 and 5% of the long term mean. Bloater biomass was much lower (1.2 kg/ha, RSE = 12%) than in the 1990s, and mean density of small bloater in 2012 (191 fish/ha, RSE = 24%) was lower than peak values observed in 2007-2009. In 2012, pelagic prey fish biomass in Lake Michigan was similar to Lake Superior and Lake Huron. Prey fish biomass remained well below the Fish Community Objectives target of 500-800 kt, and key native species remain absent or rare.","language":"English","publisher":"U.S. Geological

In contrast to most arc magma systems, where multiple episodes of open-system behavior obscure the evidence of major magma chamber events (e.g. melt extraction, magma mixing), the Quizapu magma system shows limited petrographic complexity in two large historical eruptions (1846–1847 and 1932) that have contrasting eruptive styles. Quizapu magmas and peripheral mafic magmas exhibit a simple binary mixing relationship. At the mafic end, basaltic andesite to andesite recharge magmas complement the record from peripheral cones and show the same limited range of compositions. The silicic end-member composition is almost identical in both eruptions of Quizapu. The effusive 1846–1847 eruption records significant mixing between the mafic and silicic end-members, resulting in hybridized andesites and mingled dacites. These two compositionally simple eruptions at Volcán Quizapu present a rare opportunity to isolate particular aspects of magma evolution—formation of homogeneous dacite magma and late-stage magma mixing—from other magma chamber processes. Crystal zoning, trace element compositions, and crystal-size distributions provide evidence for spatial separation of the mafic and silicic magmas. Dacite-derived plagioclase phenocrysts (i.e. An</span><sub>25</sub><sub>–</sub><sub>40</sub><span>) show a narrow range in composition and limited zonation, suggesting growth from a compositionally restricted melt. Dacite-derived amphibole phenocrysts show similar restricted compositions and furthermore constrain, together with more mafic amphibole phenocrysts, the architecture of the magmatic system at Volcán Quizapu to be compositionally and thermally zoned, in which an andesitic mush is overlain by a homogeneous dacitic magma that is the source for most of the 1846–1847 and 1932 erupted magmas. Dacite formation is best explained by mineral–melt separation (crystal fractionation) from an andesitic mush, which is inferred to have thermally and compositionally buffered the dacite magma thereby keeping it at relatively low crystallinity (&lt;30 vol. %). The dominant cause of compositional diversity is melt separation. Back-mixing of mush (i.e. crystals with signatures of growth both in the andesitic mush and in the dacite magma) into the overlying dacite magma is rarely observed. Recharge events that increase crystal and magma diversity in the dacite magma are limited to an episode of mafic recharge and mixing just prior to the 1846–1847 eruption, where evidence for magma mixing is present on all scales. Chamber-wide mixing was incomplete (mixing efficiency of ∼0·53–0·85) as flow lobes vary significantly in composition along the proposed mixing array. Estimates of viscosity variations during the course of magma mixing suggest that mixing dynamics and the degree of magma interaction on all scales were established at the beginning of the recharge event.</span></p>","language":"English","publisher":"Oxford University Press","doi":"10.1093/petrology/egs002","usgsCitation":"Bergantz, G.W., Cooper, K.M., Hildreth, E., and Ruprecht, P., 2012, The crustal magma storage system of Volcán Quizapu, Chile, and the effects of magma mixing on magma diversity: Journal of Petrology, v. 53, no. 4, p. 801-840, https://doi.org/10.1093/petrology/egs002.","productDescription":"40 p.","startPage":"801","endPage":"840","ipdsId":"IP-035772","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":347400,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Chile","otherGeospatial":"Volcán Quizapu","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -74.2236328125,\n              -36.49197347059368\n            ],\n            [\n              -66.8408203125,\n              -36.49197347059368\n            ],\n            [\n              -66.8408203125,\n              -30.44867367928756\n            ],\n            [\n              -74.2236328125,\n              -30.44867367928756\n            ],\n            [\n              -74.2236328125,\n              -36.49197347059368\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"53","issue":"4","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2012-02-04","publicationStatus":"PW","scienceBaseUri":"59f1a2aae4b0220bbd9d9fcd","contributors":{"authors":[{"text":"Bergantz, George W.","contributorId":198300,"corporation":false,"usgs":false,"family":"Bergantz","given":"George","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":715647,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cooper, Kari M.","contributorId":32814,"corporation":false,"usgs":true,"family":"Cooper","given":"Kari","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":715648,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hildreth, Edward 0000-0002-7925-4251 hildreth@usgs.gov","orcid":"https://orcid.org/0000-0002-7925-4251","contributorId":146999,"corporation":false,"usgs":true,"family":"Hildreth","given":"Edward","email":"hildreth@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":715646,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ruprecht, Phillipp","contributorId":198302,"corporation":false,"usgs":false,"family":"Ruprecht","given":"Phillipp","email":"","affiliations":[],"preferred":false,"id":715649,"contributorType":{"id":1,"text":"Authors"},"rank":13}]}}

This creek is a major tributary to the White Salmon River upstream of Condit Dam, which was breached in October 2011. Habitat and fish populations were characterized in four stream reaches. Reach breaks were based on stream gradient, water withdrawals, and fish barriers. Buck Creek generally was confined, with a single straight channel and low sinuosity. Boulders and cobble were the dominant stream substrate, with limited gravel available for spawning. Large-cobble riffles were 83 percent of the available fish habitat. Pools, comprising 15 percent of the surface area, mostly were formed by bedrock with little instream cover and low complexity. Instream wood averaged 6—10 pieces per 100 meters, 80 percent of which was less than 50 centimeters in diameter. Water temperature in Buck Creek rarely exceeded 16 degrees Celsius and did so for only 1 day at river kilometer (rkm) 3 and 11 days at rkm 0.2 in late July and early August 2009. The maximum temperature recorded was 17.2 degrees Celsius at rkm 0.2 on August 2, 2009. Minimum summer discharge in Buck Creek was 3.3 cubic feet per second downstream of an irrigation diversion (rkm 3.1) and 7.7 cubic feet per second at its confluence with the White Salmon River. Rainbow trout (<i>Oncorhynchus mykiss</i>) was the dominant fish species in all reaches. The abundance of age-1 or older rainbow trout was similar between reaches. However, in 2009 and 2010, the greatest abundance of age-0 rainbow trout (8 fish per meter) was in the most downstream reach. These analyses in Buck Creek are important for understanding the factors that may limit fish abundance and productivity, and they will help identify and prioritize potential restoration actions. The data collected constitute baseline information of pre-dam removal conditions that will allow assessment of changes in fish populations now that Condit Dam has been removed and anadromous fish have an opportunity to recolonize Buck Creek.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20121270","collaboration":"Prepared in cooperation with the Yakama Nation","usgsCitation":"Allen, M.B., Burkhardt, J., Munz, C., and Connolly, P., 2012, Fish population and habitat analysis in Buck Creek, Washington, prior to recolonization by anadromous salmonids after the removal of Condit Dam: U.S. Geological Survey Open-File Report 2012-1270, vi, 38 p., https://doi.org/10.3133/ofr20121270.","productDescription":"vi, 38 p.","numberOfPages":"48","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":264718,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2012_1270.jpg"},{"id":264717,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2012/1270/pdf/ofr20121270.pdf"},{"id":264716,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2012/1270/"}],"country":"United States","state":"Washington","otherGeospatial":"Buck Creek;Condit Dam;White Salmon River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.57,45.76 ], [ -121.57,45.85 ], [ -121.51,45.85 ], [ -121.51,45.76 ], [ -121.57,45.76 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50d4cbcae4b0c6073c902059","contributors":{"authors":[{"text":"Allen, M.
