Both increased corn growth for ethanol production and perennial dedicated energy crop growth for cellulosic feedstocks are potential sources to meet the rising demand for biofuels. However, these measures may cause adverse environmental consequences that are not yet fully understood. This study 1) evaluates the long-term impacts of increased frequency of corn in the crop rotation system on water quantity and quality as well as soil fertility in the James River Basin and 2) identifies potential grasslands for cultivating bioenergy crops (e.g. switchgrass), estimating the water quality impacts. We selected the soil and water assessment tool, a physically based multidisciplinary model, as the modeling approach to simulate a series of biofuel production scenarios involving crop rotation and land cover changes. The model simulations with different crop rotation scenarios indicate that decreases in water yield and soil nitrate nitrogen (NO<sub>3</sub>-N) concentration along with an increase in NO<sub>3</sub>-N load to stream water could justify serious concerns regarding increased corn rotations in this basin. Simulations with land cover change scenarios helped us spatially classify the grasslands in terms of biomass productivity and nitrogen loads, and we further derived the relationship of biomass production targets and the resulting nitrogen loads against switchgrass planting acreages. The suggested economically efficient (planting acreage) and environmentally friendly (water quality) planting locations and acreages can be a valuable guide for cultivating switchgrass in this basin. This information, along with the projected environmental costs (i.e. reduced water yield and increased nitrogen load), can contribute to decision support tools for land managers to seek the sustainability of biofuel development in this region.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GCB Bioenergy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1757-1707.2012.01164.x","usgsCitation":"Wu, Y., Liu, S., and Li, Z., 2012, Identifying potential areas for biofuel production and evaluating the environmental effects: a case study of the James River Basin in the Midwestern United States: GCB Bioenergy, v. 4, no. 6, p. 875-888, https://doi.org/10.1111/j.1757-1707.2012.01164.x.","productDescription":"14 p.","startPage":"875","endPage":"888","ipdsId":"IP-033265","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":474133,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1757-1707.2012.01164.x","text":"Publisher Index Page"},{"id":273334,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273333,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1757-1707.2012.01164.x"}],"country":"United States","state":"Missouri","otherGeospatial":"James River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -95.7747,35.9957 ], [ -95.7747,40.6136 ], [ -89.0995,40.6136 ], [ -89.0995,35.9957 ], [ -95.7747,35.9957 ] ] ] } } ] }","volume":"4","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-02-27","publicationStatus":"PW","scienceBaseUri":"51b05de6e4b030b51980122f","contributors":{"authors":[{"text":"Wu, Yiping ywu@usgs.gov","contributorId":987,"corporation":false,"usgs":true,"family":"Wu","given":"Yiping","email":"ywu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":473496,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, Shu-Guang sliu@usgs.gov","contributorId":984,"corporation":false,"usgs":true,"family":"Liu","given":"Shu-Guang","email":"sliu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":473495,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Li, Zhengpeng","contributorId":80812,"corporation":false,"usgs":true,"family":"Li","given":"Zhengpeng","affiliations":[],"preferred":false,"id":473497,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The precise impacts will, however, strongly depend on socioeconomic conditions such as local markets and food import dependence. In the near term, two factors are also changing the nature of food security: (1) rapid urbanization, with the proportion of the global population living in urban areas expanding from 13 percent in 1975 to greater than 50 percent at present, and (2) trade and domestic market liberalization since 1993, which has promoted removal of import controls, deregulation of prices, and the loss of preferential markets for many small economies.\n\nOver the last two years, the worst drought in decades has devastated eastern Africa. The resulting food-security crisis has affected roughly 13 million people and has reminded us that there is still a long way to go in addressing current climate-related risks. In the face of such profound changes and uncertainties, our approaches to food security must evolve. In this article, we describe four key elements that, in our view, will be essential to the success of efforts to address the linked challenges of food security and climate change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Solutions Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Solutions","usgsCitation":"Pulwarty, R., Eilerts, G., and Verdin, J., 2012, Food security in a changing climate: Solutions Journal, v. 3, no. 1, p. 31-34.","productDescription":"4 p.","startPage":"31","endPage":"34","ipdsId":"IP-037246","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":272781,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272780,"type":{"id":15,"text":"Index Page"},"url":"https://www.thesolutionsjournal.com/node/1054"}],"volume":"3","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51a08be0e4b0e4245580656e","contributors":{"authors":[{"text":"Pulwarty, Roger","contributorId":28149,"corporation":false,"usgs":true,"family":"Pulwarty","given":"Roger","affiliations":[],"preferred":false,"id":473333,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eilerts, Gary","contributorId":31101,"corporation":false,"usgs":true,"family":"Eilerts","given":"Gary","email":"","affiliations":[],"preferred":false,"id":473334,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Verdin, James 0000-0003-0238-9657","orcid":"https://orcid.org/0000-0003-0238-9657","contributorId":99647,"corporation":false,"usgs":true,"family":"Verdin","given":"James","affiliations":[],"preferred":false,"id":473335,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Thus, the BCS has the highest time-dependent earthquake probability of the central WFZ. We excavated trenches at three sites––the Kotter Canyon and Hansen Canyon sites on the north-central BCS and Pearsons Canyon site on the southern BCS––to determine whether a surface-faulting earthquake younger than 2.1 ka occurred on the BCS. Paleoseismic data for Hansen Canyon and Kotter Canyon confirm that the youngest earthquake on the north-central BCS occurred before 2 ka, consistent with previous north-central BCS investigations at Bowden Canyon and Box Elder Canyon. At Hansen Canyon, the most recent earthquake is constrained to 2.1–4.2 ka and had 0.6–2.5 m of vertical displacement. At Kotter Canyon, we found evidence for two events at 2.5 ± 0.3 ka and 3.5 ± 0.3 ka, with an average displacement per event of 1.9–2.3 m. Paleoseismic data from Pearsons Canyon, on the previously unstudied southern BCS, indicate that a post-2 ka earthquake ruptured this part of the segment. The Pearsons Canyon earthquake occurred at 1.2 ± 0.04 ka and had 0.1–0.8 m of vertical displacement, consistent with our observation of continuous, youthful scarps on the southern 9 km of the BCS having 1–2 m of late Holocene(?) surface offset. The 1.2-ka earthquake on the southern BCS likely represents rupture across the Weber–Brigham City segment boundary from the penultimate Weber-segment earthquake at about 1.1 ka. The Pearsons Canyon data result in a revised length of the BCS that has not ruptured since 2 ka (with time-dependent probability implications), and provide compelling evidence of at least one segment-boundary failure and multi-segment rupture on the central WFZ. Our paleoseismic investigations of the BCS clarify the timing, displacement, and extent of late Holocene earthquakes on the segment, and importantly, confirm the long elapsed time since the most recent earthquake on most of the BCS.","language":"English","publisher":"Utah Geological Survey","collaboration":"This report is volume 22 in the series Paleoseismology of Utah","usgsCitation":"DuRoss, C., Personius, S.F., Crone, A.J., McDonald, G.N., and Briggs, R., 2012, Late Holocene earthquake history of the Brigham City segment of the Wasatch fault zone at the Hansen Canyon, Kotter Canyon, and Pearsons Canyon trench sites, Box Elder County, Utah: Special Study 142, vii, 62 p.","productDescription":"vii, 62 p.","numberOfPages":"69","ipdsId":"IP-039461","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":274055,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274054,"type":{"id":11,"text":"Document"},"url":"https://geology.utah.gov/online/ss/ss-142/ss-142.pdf"}],"country":"United States","state":"Utah","county":"Box Elder County","otherGeospatial":"Hansen Canyon;Kotter Canyon;Pearsons Canyon","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.0426,40.9977 ], [ -114.0426,42.0012 ], [ -111.868,42.0012 ], [ -111.868,40.9977 ], [ -114.0426,40.9977 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51c59e35e4b0c89b8f120e49","contributors":{"authors":[{"text":"DuRoss, Christopher B.","contributorId":66532,"corporation":false,"usgs":true,"family":"DuRoss","given":"Christopher B.","affiliations":[],"preferred":false,"id":476849,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Personius, Stephen F. personius@usgs.gov","contributorId":1214,"corporation":false,"usgs":true,"family":"Personius","given":"Stephen","email":"personius@usgs.gov","middleInitial":"F.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":476847,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Crone, Anthony J. 0000-0002-3006-406X crone@usgs.gov","orcid":"https://orcid.org/0000-0002-3006-406X","contributorId":790,"corporation":false,"usgs":true,"family":"Crone","given":"Anthony","email":"crone@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":476846,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McDonald, Greg N.","contributorId":43658,"corporation":false,"usgs":true,"family":"McDonald","given":"Greg","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":476848,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Briggs, Richard W.","contributorId":94027,"corporation":false,"usgs":true,"family":"Briggs","given":"Richard W.","affiliations":[],"preferred":false,"id":476850,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The BCM calculates water balance components, including runoff, recharge, evapotranspiration, soil moisture, and stream flow, based on climate, topography, soils and underlying geology, and the solar-driven energy balance. We downscaled historical and projected precipitation and air temperature values derived from weather stations and global General Circulation Models (GCMs) to a spatial scale of 270 m. We then used the BCM to estimate hydrologic response to climate change for four scenarios spanning this century (2000–2100). Historical climate patterns show that Marin’s coastal regions are typically on the order of 2 °C cooler and receive five percent more precipitation compared to the inland valleys of Sonoma and Napa because of marine influences and local topography. By the last 30 years of this century, North Bay scenarios project average minimum temperatures to increase by 1.0 °C to 3.1 °C and average maximum temperatures to increase by 2.1 °C to 3.4 °C (in comparison to conditions experienced over the last 30 years, 1981–2010). Precipitation projections for the 21st century vary between GCMs (ranging from 2 to 15% wetter than the 20th-century average). Temperature forcing increases the variability of modeled runoff, recharge, and stream discharge, and shifts hydrologic cycle timing. For both high- and low-rainfall scenarios, by the close of this century warming is projected to amplify late-season climatic water deficit (a measure of drought stress on soils) by 8% to 21%. Hydrologic variability within a single river basin demonstrated at the scale of subwatersheds may prove an important consideration for water managers in the face of climate change. Our results suggest that in arid environments characterized by high topo-climatic variability, land and water managers need indicators of local watershed hydrology response to complement regional temperature and precipitation estimates. Our results also suggest that temperature forcing may generate greater drought stress affecting soils and stream flows than can be estimated by variability in precipitation alone.","language":"English","publisher":"University of California","doi":"10.15447/sfews.2012v10iss4art2","usgsCitation":"Micheli, E., Flint, L., Flint, A., Weiss, S., and Kennedy, M., 2012, Downscaling future climate projections to the watershed scale: A north San Francisco Bay estuary case study: San Francisco Estuary and Watershed Science, v. 10, no. 4, 31 p., https://doi.org/10.15447/sfews.2012v10iss4art2.","productDescription":"31 p.","ipdsId":"IP-028558","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true}],"links":[{"id":474239,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.15447/sfews.2012v10iss4art2","text":"Publisher Index Page"},{"id":381884,"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\": [ [ [ -123.0,37.0 ], [ -123.0,38.5 ], [ -121.5,38.5 ], [ -121.5,37.0 ], [ -123.0,37.0 ] ] ] } } ] }","volume":"10","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-12-05","publicationStatus":"PW","scienceBaseUri":"51838ae6e4b0a21483941a8e","contributors":{"authors":[{"text":"Micheli, Elisabeth","contributorId":105615,"corporation":false,"usgs":true,"family":"Micheli","given":"Elisabeth","email":"","affiliations":[],"preferred":false,"id":477892,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flint, Lorraine 0000-0002-7868-441X","orcid":"https://orcid.org/0000-0002-7868-441X","contributorId":97753,"corporation":false,"usgs":true,"family":"Flint","given":"Lorraine","affiliations":[],"preferred":false,"id":477891,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Flint, Alan","contributorId":58503,"corporation":false,"usgs":true,"family":"Flint","given":"Alan","email":"","affiliations":[],"preferred":false,"id":477889,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Weiss, Stuart","contributorId":7590,"corporation":false,"usgs":true,"family":"Weiss","given":"Stuart","email":"","affiliations":[],"preferred":false,"id":477888,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kennedy, Morgan","contributorId":77446,"corporation":false,"usgs":true,"family":"Kennedy","given":"Morgan","email":"","affiliations":[],"preferred":false,"id":477890,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

If actual measurement conditions are not consistent with those encountered in the empirical or laboratory studies, these methods may give poor estimates of discharge uncertainty. This paper presents an alternative method for estimating discharge measurement uncertainty that uses statistical techniques and at-site observations. This Interpolated Variance Estimator (IVE) estimates uncertainty based on the data collected during the streamflow measurement and therefore reflects the conditions encountered at the site. The IVE has the additional advantage of capturing all sources of random uncertainty in the velocity and depth measurements. It can be applied to velocity-area discharge measurements that use a velocity meter to measure point velocities at multiple vertical sections in a channel cross section.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydraulic Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ASCE","publisherLocation":"Reston, VA","doi":"10.1061/(ASCE)HY.1943-7900.0000695","usgsCitation":"Cohn, T., Kiang, J., and Mason, R., 2012, Estimating discharge measurement uncertainty using the interpolated variance estimator: Journal of Hydraulic Engineering, v. 139, no. 5, p. 502-510, https://doi.org/10.1061/(ASCE)HY.1943-7900.0000695.","productDescription":"9 p.","startPage":"502","endPage":"510","ipdsId":"IP-022663","costCenters":[{"id":502,"text":"Office of Surface Water","active":true,"usgs":true}],"links":[{"id":269975,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269974,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)HY.1943-7900.0000695"}],"volume":"139","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5150207ee4b08df5cb131360","contributors":{"authors":[{"text":"Cohn, T.","contributorId":95353,"corporation":false,"usgs":true,"family":"Cohn","given":"T.","email":"","affiliations":[],"preferred":false,"id":463432,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kiang, J.","contributorId":31280,"corporation":false,"usgs":true,"family":"Kiang","given":"J.","email":"","affiliations":[],"preferred":false,"id":463430,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mason, R.

To understand the relationship between physiological stress and translocation, we conducted a multiyear study (2007–2009) using a population of desert tortoises (Gopherus agassizii) near Fort Irwin, California. Blood samples were collected from adult tortoises in three treatment groups (resident, translocated and control) for 1 year prior to and 2 years after translocation. Samples were analyzed by radioimmunoassay for plasma total corticosterone (CORT), a glucocorticoid hormone commonly associated with stress responses in reptiles. CORT values were analyzed in relation to potential covariates (animal sex, date, behavior, treatment, handling time, air temperature, home-range size, precipitation and annual plant production) among seasons and years. CORT values in males were higher than in females, and values for both varied monthly throughout the activity season and among years. Year and sex were strong predictors of CORT, and translocation explained little in terms of CORT. Based on these results, we conclude that translocation does not elicit a physiological stress response in desert tortoises.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Animal Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1469-1795.2012.00549.x","usgsCitation":"Drake, K., Nussear, K., Esque, T., Barber, A., Vittum, K., Medica, P., Tracy, C., and Hunter, K., 2012, Does translocation influence physiological stress in the desert tortoise?: Animal Conservation, v. 15, no. 6, p. 560-570, https://doi.org/10.1111/j.1469-1795.2012.00549.x.","productDescription":"11 p.","startPage":"560","endPage":"570","ipdsId":"IP-036103","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":271766,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271765,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1469-1795.2012.00549.x"}],"country":"United States","state":"California","city":"Fort Irwin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.0,35.0 ], [ -117.0,35.5 ], [ -116.0,35.5 ], [ -116.0,35.0 ], [ -117.0,35.0 ] ] ] } } ] }","volume":"15","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-05-16","publicationStatus":"PW","scienceBaseUri":"51838ae5e4b0a21483941a8a","contributors":{"authors":[{"text":"Drake, K.K.","contributorId":85775,"corporation":false,"usgs":true,"family":"Drake","given":"K.K.","email":"","affiliations":[],"preferred":false,"id":472225,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nussear, K.E.","contributorId":80227,"corporation":false,"usgs":true,"family":"Nussear","given":"K.E.","affiliations":[],"preferred":false,"id":472224,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Esque, T.

This study examined thresholds of bed disturbances that affected patch- and reach-scale sediment conditions and metabolism rates. A 4 year record of discharge and diel changes in dissolved oxygen concentrations (ΔDO) was analyzed for disturbances and recovery periods of the ΔDO signal. Disturbances to the ΔDO signal were associated with flow pulses, and the recovery times for the ΔDO signal were found to be in two categories: less than 5 days (30% of the disturbances) or greater than 15 days (70% of the disturbances). A field study was performed during the fall of 2007, which included a storm event that increased discharge from 3.1 to 6.9 m<sup>3</sup>/s over a 7 h period. During stable flow conditions before the storm, variability in patch-scale stream metabolism values were associated with sediment texture classes with values ranging from −16.4 to 2.3 g O<sub>2</sub></m<sup>2</sup>/d (negative sign indicates net respiration) that bounded the reach-averaged rate of −5.6 g O<sub>2</sub></m<sup>2</sup>/d. Hydraulic modeling of bed shear stresses demonstrated a storm-induced flow pulse mobilized approximately 25% of the bed and reach-scale metabolism rates shifted from −5 to −40 g O<sub>2</sub></m<sup>2</sup>/d. These results suggest that storm-induced bed disturbances led to threshold behavior with respect to stream metabolism. Small flow pulses resulted in partial-bed mobilization that disrupted stream metabolism by increased turbidity with short recovery times. Large flow pulses resulted in full-bed mobilization that disrupted stream metabolism by destroying periphyton habitats with long recovery times.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AGU","publisherLocation":"Washington, D.C.","doi":"10.1029/2011WR011488","usgsCitation":"O’Connor, B.L., Harvey, J.W., and McPhillips, L.E., 2012, Thresholds of flow-induced bed disturbances and their effects on stream metabolism in an agricultural river: Water Resources Research, v. 48, no. 8, W08504, https://doi.org/10.1029/2011WR011488.","productDescription":"W08504","ipdsId":"IP-037433","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":474128,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2011wr011488","text":"Publisher Index Page"},{"id":270728,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":270727,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011WR011488"}],"volume":"48","issue":"8","noUsgsAuthors":false,"publicationDate":"2012-08-04","publicationStatus":"PW","scienceBaseUri":"51653873e4b077fa94dae026","contributors":{"authors":[{"text":"O’Connor, Ben L.","contributorId":38872,"corporation":false,"usgs":false,"family":"O’Connor","given":"Ben","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":475520,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harvey, Judson W. 0000-0002-2654-9873 jwharvey@usgs.gov","orcid":"https://orcid.org/0000-0002-2654-9873","contributorId":1796,"corporation":false,"usgs":true,"family":"Harvey","given":"Judson","email":"jwharvey@usgs.gov","middleInitial":"W.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475518,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McPhillips, Lauren E.","contributorId":15491,"corporation":false,"usgs":true,"family":"McPhillips","given":"Lauren","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":475519,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

It is important to interpret responses to contaminants relative to other environmental factors, but necessity or convenience limit quantification of all factors that influence ecological potential. In these situations, the concept of limiting factors is useful for data interpretation. We used quantile regression to measure risks to aquatic life exposed to metals by including all regression quantiles (τ  =  0.05–0.95, by increments of 0.05), not just the upper limit of density (e.g., 90<sup>th</sup> quantile). We measured population densities (individuals/0.1 m<sup>2</sup>) of 2 mayflies (Rhithrogena spp., Drunella spp.) and a caddisfly (Arctopsyche grandis), aqueous metal mixtures (Cd, Cu, Zn), and other limiting factors (basin area, site elevation, discharge, temperature) at 125 streams in Colorado. We used a model selection procedure to test which factor was most limiting to density. Arctopsyche grandis was limited by other factors, whereas metals limited most quantiles of density for the 2 mayflies. Metals reduced mayfly densities most at sites where other factors were not limiting. Where other factors were limiting, low mayfly densities were observed despite metal concentrations. Metals affected mayfly densities most at quantiles above the mean and not just at the upper limit of density. Risk models developed from quantile regression showed that mayfly densities observed at background metal concentrations are improbable when metal mixtures are at US Environmental Protection Agency criterion continuous concentrations. We conclude that metals limit potential density, not realized average density. The most obvious effects on mayfly populations were at upper quantiles and not mean density. Therefore, we suggest that policy developed from mean-based measures of effects may not be as useful as policy based on the concept of limiting factors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Society for Freshwater Science","doi":"10.1899/11-133.1","usgsCitation":"Schmidt, T., Clements, W.H., and Cade, B.S., 2012, Estimating risks to aquatic life using quantile regression: Freshwater Science, v. 31, no. 3, p. 709-723, https://doi.org/10.1899/11-133.1.","productDescription":"15 p.","startPage":"709","endPage":"723","ipdsId":"IP-017391","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":274071,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274070,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1899/11-133.1"}],"country":"United States","state":"Colorado","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.06,36.99 ], [ -109.06,41.0 ], [ -102.04,41.0 ], [ -102.04,36.99 ], [ -109.06,36.99 ] ] ] } } ] }","volume":"31","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51c59e33e4b0c89b8f120e27","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":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":685,"text":"Wyoming-Montana Water Science Center","active":false,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":476308,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Clements, William H.","contributorId":39504,"corporation":false,"usgs":true,"family":"Clements","given":"William","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":476309,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cade, Brian S. 0000-0001-9623-9849 cadeb@usgs.gov","orcid":"https://orcid.org/0000-0001-9623-9849","contributorId":1278,"corporation":false,"usgs":true,"family":"Cade","given":"Brian","email":"cadeb@usgs.gov","middleInitial":"S.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":476307,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To test the impacts of predicted climate change scenarios on biocrusts in a dryland ecosystem, the effects of a 2–3 °C increase in soil temperature and an increased frequency of smaller summer precipitation events were examined in a large, replicated field study conducted in the cold desert of the Colorado Plateau, USA. Surface soil biomass (DNA concentration), photosynthetically active cyanobacterial biomass (chlorophyll a concentration), cyanobacterial abundance (quantitative PCR assay), and bacterial community composition (16S rRNA gene sequencing) were monitored seasonally over 2 years. Soil microbial biomass and bacterial community composition were highly stratified between the 0–2 cm depth biocrusts and 5–10 cm depth soil beneath the biocrusts. The increase in temperature did not have a detectable effect on any of the measured parameters over 2 years. However, after the second summer of altered summer precipitation pattern, significant declines occurred in the surface soil biomass (avg. DNA concentration declined 38%), photosynthetic cyanobacterial biomass (avg. chlorophyll a concentration declined 78%), cyanobacterial abundance (avg. gene copies g<sup>−1</sup> soil declined 95%), and proportion of Cyanobacteria in the biocrust bacterial community (avg. representation in sequence libraries declined 85%). Biocrusts are important contributors to soil stability, soil C and N stores, and plant performance, and the loss or reduction of biocrusts under an altered precipitation pattern associated with climate change could contribute significantly to lower soil fertility and increased erosion and dust production in dryland ecosystems at a regional scale.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Global Change Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2486.2012.02709.x","usgsCitation":"Johnson, S.L., Kuske, C.R., Carney, T.D., Housman, D.C., Gallegos-Graves, L., and Belnap, J., 2012, Increased temperature and altered summer precipitation have differential effects on biological soil crusts in a dryland ecosystem: Global Change Biology, v. 18, no. 8, p. 2583-2593, https://doi.org/10.1111/j.1365-2486.2012.02709.x.","productDescription":"11 p.","startPage":"2583","endPage":"2593","ipdsId":"IP-037065","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":273420,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273419,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2486.2012.02709.x"}],"volume":"18","issue":"8","noUsgsAuthors":false,"publicationDate":"2012-05-09","publicationStatus":"PW","scienceBaseUri":"51b1bbd4e4b022a6a540f9f7","contributors":{"authors":[{"text":"Johnson, Shannon L.","contributorId":22643,"corporation":false,"usgs":true,"family":"Johnson","given":"Shannon","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":474366,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kuske, Cheryl R.","contributorId":81063,"corporation":false,"usgs":false,"family":"Kuske","given":"Cheryl","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":474368,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carney, Travis D.","contributorId":15486,"corporation":false,"usgs":true,"family":"Carney","given":"Travis","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":474365,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Housman, David C.","contributorId":60752,"corporation":false,"usgs":false,"family":"Housman","given":"David","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":474367,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Gallegos-Graves, La Verne","contributorId":97408,"corporation":false,"usgs":true,"family":"Gallegos-Graves","given":"La Verne","affiliations":[],"preferred":false,"id":474369,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Belnap, Jayne 0000-0001-7471-2279 jayne_belnap@usgs.gov","orcid":"https://orcid.org/0000-0001-7471-2279","contributorId":1332,"corporation":false,"usgs":true,"family":"Belnap","given":"Jayne","email":"jayne_belnap@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":474364,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

This fishery would benefit from improved stock assessment capabilities. Larval crab distribution is patchy temporally and spatially, requiring extensive sampling efforts to locate and track larval dispersal. Large-scale plankton surveys are generally cost prohibitive because of the effort required for collection and the time and taxonomic expertise required to sort samples to identify plankton individually via light microscopy. Here, we report the development of primers and a dual-labeled probe for use in a DNA-based real-time polymerase chain reaction assay targeting the red king crab, mitochondrial gene cytochrome oxidase I for the detection of red king crab larvae DNA in plankton samples. The assay allows identification of plankton samples containing crab larvae DNA and provides an estimate of DNA copy number present in a sample without sorting the plankton sample visually. The assay was tested on DNA extracted from whole red king crab larvae and plankton samples seeded with whole larvae, and it detected DNA copies equivalent to 1/10,000th of a larva and 1 crab larva/5mL sieved plankton, respectively. The real-time polymerase chain reaction assay can be used to screen plankton samples for larvae in a fraction of the time required for traditional microscopial methods, which offers advantages for stock assessment methodologies for red king crab as well as a rapid and reliable method to assess abundance of red king crab larvae as needed to improve the understanding of life history and population processes, including larval population dynamics.</p>","language":"English","publisher":"National Shellfisheries Association","doi":"10.2983/035.031.0402","usgsCitation":"Jensen, P.C., Purcell, M., Morado, J.F., and Eckert, G.L., 2012, Development of a real-time PCR assay for detection of planktonic red king crab (<i>Paralithodes camtschaticus</i> (Tilesius 1815)) larvae: Journal of Shellfish Research, v. 31, no. 4, p. 917-924, https://doi.org/10.2983/035.031.0402.","productDescription":"8 p.","startPage":"917","endPage":"924","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-037763","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":271443,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"517a5062e4b072c16ef14aeb","contributors":{"authors":[{"text":"Jensen, Pamela C.","contributorId":38877,"corporation":false,"usgs":true,"family":"Jensen","given":"Pamela","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":474546,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Purcell, Maureen K.","contributorId":104214,"corporation":false,"usgs":true,"family":"Purcell","given":"Maureen K.","affiliations":[],"preferred":false,"id":474548,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Morado, J.

Concentration methods tend to be specific for a particular pathogen group, for example US Environmental Protection Agency Method 1623 for Giardia and Cryptosporidium1, which means multiple methods are required if the sampling program is targeting more than one pathogen group. Another drawback of current methods is the equipment can be complicated and expensive, for example the VIRADEL method with the 1MDS cartridge filter for concentrating viruses2. In this article we describe how to construct glass wool filters for concentrating waterborne pathogens. After filter elution, the concentrate is amenable to a second concentration step, such as centrifugation, followed by pathogen detection and enumeration by cultural or molecular methods. The filters have several advantages. Construction is easy and the filters can be built to any size for meeting specific sampling requirements. The filter parts are inexpensive, making it possible to collect a large number of samples without severely impacting a project budget. Large sample volumes (100s to 1,000s L) can be concentrated depending on the rate of clogging from sample turbidity. The filters are highly portable and with minimal equipment, such as a pump and flow meter, they can be implemented in the field for sampling finished drinking water, surface water, groundwater, and agricultural runoff. Lastly, glass wool filtration is effective for concentrating a variety of pathogen types so only one method is necessary. Here we report on filter effectiveness in concentrating waterborne human enterovirus, Salmonella enterica, Cryptosporidium parvum, and avian influenza virus.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Visualized Experiments","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"JoVE","doi":"10.3791/3930","usgsCitation":"Millen, H.T., Gonnering, J.C., Berg, R.K., Spencer, S., Jokela, W.E., Pearce, J.M., Borchardt, J., and Borchardt, M., 2012, Glass wool filters for concentrating waterborne viruses and agricultural zoonotic pathogens: Journal of Visualized Experiments, v. 61, e3930, https://doi.org/10.3791/3930.","productDescription":"e3930","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":474124,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.3791/3930","text":"External Repository"},{"id":271752,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271751,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3791/3930"}],"volume":"61","noUsgsAuthors":false,"publicationDate":"2012-03-03","publicationStatus":"PW","scienceBaseUri":"51838ae9e4b0a21483941aae","contributors":{"authors":[{"text":"Millen, Hana T. htmillen@usgs.gov","contributorId":4017,"corporation":false,"usgs":true,"family":"Millen","given":"Hana","email":"htmillen@usgs.gov","middleInitial":"T.","affiliations":[],"preferred":true,"id":478290,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gonnering, Jordan C. jgonneri@usgs.gov","contributorId":5199,"corporation":false,"usgs":true,"family":"Gonnering","given":"Jordan","email":"jgonneri@usgs.gov","middleInitial":"C.","affiliations":[],"preferred":true,"id":478291,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Berg, Ryan K.","contributorId":89784,"corporation":false,"usgs":true,"family":"Berg","given":"Ryan","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":478295,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Spencer, Susan K.","contributorId":39511,"corporation":false,"usgs":true,"family":"Spencer","given":"Susan K.","affiliations":[],"preferred":false,"id":478293,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Jokela, William E.","contributorId":32806,"corporation":false,"usgs":true,"family":"Jokela","given":"William","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":478292,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"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":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":478289,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Borchardt, Jackson S.","contributorId":81388,"corporation":false,"usgs":true,"family":"Borchardt","given":"Jackson S.","affiliations":[],"preferred":false,"id":478294,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Borchardt, Mark A.","contributorId":106255,"corporation":false,"usgs":true,"family":"Borchardt","given":"Mark A.","affiliations":[],"preferred":false,"id":478296,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Global Fe/O and Fe/Si ratios are consistent with HED compositions. Neutron measurements confirm that a thick, diogenitic lower crust is exposed in the Rheasilvia basin, which is consistent with global magmatic differentiation. Vesta’s regolith contains substantial amounts of hydrogen. The highest hydrogen concentrations coincide with older, low-albedo regions near the equator, where water ice is unstable. The young, Rheasilvia basin contains the lowest concentrations. These observations are consistent with gradual accumulation of hydrogen by infall of carbonaceous chondrites—observed as clasts in some howardites—and subsequent removal or burial of this material by large impacts.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal

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":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","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}]}}

The influence of herbivory on plants and ultimately ecosystem processes is shaped by the types of plants consumed, the intensity of herbivory, the evolutionary history of grazing, and the availability of water and nutrients to plants. The effect of ungulate herbivores on vegetation is of great interest to ecologists, land managers and agriculturalists. In addition, the Department of Interior recently established a Bison Conservation Initiative to provide for the conservation and restoration of North American plains- and wood bison, which includes establishing new populations and expanding existing populations. The San Luis Valley, Colorado, is being considered as a potential location for a bison conservation herd.

Mitigation of potential fire behaviour and fire severity have increasingly been attempted through pre-fire alteration of wildland fuels using mechanical treatments and prescribed fires. Despite annual treatment of more than a million hectares of land, quantitative assessments of the effectiveness of existing fuel treatments at reducing the size of actual wildfires or how they might alter the risk of burning across landscapes are currently lacking. Here, we present a method for estimating spatial probabilities of burning as a function of extant fuels treatments for any wildland fire-affected landscape. We examined the landscape effects of more than 72 000 ha of wildland fuel treatments involved in 14 large wildfires that burned 314 000 ha of forests in nine US states between 2002 and 2010. Fuels treatments altered the probability of fire occurrence both positively and negatively across landscapes, effectively redistributing fire risk by changing surface fire spread rates and reducing the likelihood of crowning behaviour. Trade offs are created between formation of large areas with low probabilities of increased burning and smaller, well-defined regions with reduced fire risk.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal of Wildland Fire","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"CSIRO Publishing","doi":"10.1071/WF11079","usgsCitation":"Cochrane, M., Moran, C., Wimberly, M., Baer, A., Finney, M., Beckendorf, K., Eidenshink, J., and Zhu, Z., 2012, Estimation of wildfire size and risk changes due to fuels treatments: International Journal of Wildland Fire, v. 21, no. 4, p. 357-367, https://doi.org/10.1071/WF11079.","productDescription":"11 p.","startPage":"357","endPage":"367","ipdsId":"IP-030075","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":474156,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1071/wf11079","text":"Publisher Index Page"},{"id":272209,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266988,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1071/WF11079"}],"volume":"21","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5833e4b0b290850f7ee2","contributors":{"authors":[{"text":"Cochrane, M.A.","contributorId":15896,"corporation":false,"usgs":true,"family":"Cochrane","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":472961,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moran, C.J.","contributorId":36444,"corporation":false,"usgs":true,"family":"Moran","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":472964,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wimberly, M.C.","contributorId":52864,"corporation":false,"usgs":true,"family":"Wimberly","given":"M.C.","email":"","affiliations":[],"preferred":false,"id":472965,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Baer, A.D.","contributorId":76204,"corporation":false,"usgs":true,"family":"Baer","given":"A.D.","email":"","affiliations":[],"preferred":false,"id":472966,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Finney, M.A.","contributorId":18312,"corporation":false,"usgs":true,"family":"Finney","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":472962,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Beckendorf, K.L.","contributorId":28505,"corporation":false,"usgs":true,"family":"Beckendorf","given":"K.L.","affiliations":[],"preferred":false,"id":472963,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Eidenshink, J.","contributorId":7893,"corporation":false,"usgs":true,"family":"Eidenshink","given":"J.","email":"","affiliations":[],"preferred":false,"id":472959,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Zhu, Z.","contributorId":10898,"corporation":false,"usgs":true,"family":"Zhu","given":"Z.","email":"","affiliations":[],"preferred":false,"id":472960,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

As such, we are developing an improved strategy for producing V<sub>S30</sub> maps given the common observational constraints. Using the abundant V<sub>S30</sub> measurements in Taiwan, we compare alternative mapping methods that combine topographic slope, surface geology, and spatial correlation structure. The different V<sub>S30</sub> mapping algorithms are distinguished by the way that slope and geology are combined to define a spatial model of V<sub>S30</sub>. We consider the globally applicable slope-only model as a baseline to which we compare two methods of combining both slope and geology. For both hybrid approaches, we model spatial correlation structure of the residuals using the kriging-with-a-trend technique, which brings the map into closer agreement with the observations. Cross validation indicates that we can reduce the uncertainty of the V<sub>S30</sub> map by up to 16% relative to the slope-only approach.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"The 15th World Conference on Earthquake Engineering: September 24-28, 2012, Lisbon, Portugal","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"IEM","usgsCitation":"Thompson, E., and Wald, D., 2012, Developing Vs30 site-condition maps by combining observations with geologic and topographic constraints, <i>in</i> The 15th World Conference on Earthquake Engineering: September 24-28, 2012, Lisbon, Portugal, 9 p.","productDescription":"9 p.","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":274115,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274114,"type":{"id":11,"text":"Document"},"url":"https://www.iitk.ac.in/nicee/wcee/article/WCEE2012_0953.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51c96a63e4b0a50a6e8f57ca","contributors":{"authors":[{"text":"Thompson, E.M.","contributorId":104688,"corporation":false,"usgs":true,"family":"Thompson","given":"E.M.","affiliations":[],"preferred":false,"id":479985,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wald, D.J. 0000-0002-1454-4514","orcid":"https://orcid.org/0000-0002-1454-4514","contributorId":43809,"corporation":false,"usgs":true,"family":"Wald","given":"D.J.","affiliations":[],"preferred":false,"id":479984,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In general, the radiometric performance of the instrument has been remarkably stable: 1) noise performance has degraded by 2% or less overall, with a few detectors displaying step changes in noise of 2% or less; 2) coherent noise frequencies and magnitudes have generally been stable, though the within-scan amplitude variation of the 20 kHz noise in bands 1 and 8 disappeared with the failure of the scan line corrector and a new similar frequency noise (now about 18 kHz) has appeared in two detectors in band 5 and increased in magnitude with time; 3) bias stability has been better than 0.25 DN out of a normal value of 15 DN in high gain; 4) relative gains, the differences in response between the detectors in the band, have generally changed by 0.1% or less over the mission, with the exception of a few detectors with a step response change of 1% or less; and 5) gain stability averaged across all detectors in a band, which is related to the stability of the absolute calibration, has been more stable than the techniques used to measure it. Due to the inability to confirm changes in the gain (beyond a few detectors that have been corrected back to the band average), ETM+ reflective band data continues to be calibrated with the prelaunch measured gains. In the worst case, some bands may have changed as much as 2% in uncompensated absolute calibration over the 12 years.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"IEEE Transactions on Geoscience and Remote Sensing","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"IEEE","doi":"10.1109/TGRS.2011.2169803","usgsCitation":"Markham, B.L., Haque, M., Barsi, J., Micijevic, E., Helder, D., Thome, K.J., Aaron, D., and Czapla-Myers, J.S., 2012, Landsat-7 ETM+: 12 years on-orbit reflective-band radiometric performance: IEEE Transactions on Geoscience and Remote Sensing, v. 50, no. 5, p. 2056-2062, https://doi.org/10.1109/TGRS.2011.2169803.","productDescription":"7 p.","startPage":"2056","endPage":"2062","ipdsId":"IP-030601","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":474160,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/2060/20110022534","text":"External Repository"},{"id":274020,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274019,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/TGRS.2011.2169803"}],"volume":"50","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51c42461e4b03c77dce65a55","contributors":{"authors":[{"text":"Markham, B.

There, nontidal channels and riparian floodplains are transforming into tidal ecosystems, and tidal freshwater ecosystems are receiving increasing salinity. These river-floodplain systems have both fluvial characteristics, including meandering channels and expansive floodplain forests, and estuarine characteristics, including tides and intertidal wetlands [see Barendregt et al., 2009; Conner et al., 2007, and references therein]. Because tidal rivers lie at the disciplinary divide between fluvial and estuarine science, a knowledge gap has developed in scientists' understanding of the geomorphic and biogeochemical response of these environments to sea level rise, climate change, and anthropogenically driven variations in watershed exports.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Eos, Transactions American Geophysical Union","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AGU","doi":"10.1029/2012EO450004","usgsCitation":"Ensign, S., Noe, G., Hupp, C.R., and Fagherazzi, S., 2012, A meeting of the waters: interdisciplinary challenges and opportunities in tidal rivers: Eos, Transactions, American Geophysical Union, v. 95, no. 45, p. 455-456, https://doi.org/10.1029/2012EO450004.","productDescription":"2 p.","startPage":"455","endPage":"456","ipdsId":"IP-041592","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":488181,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2012eo450004","text":"Publisher Index Page"},{"id":273754,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273753,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2012EO450004"}],"volume":"95","issue":"45","noUsgsAuthors":false,"publicationDate":"2012-11-06","publicationStatus":"PW","scienceBaseUri":"51bc3b62e4b0c04034a01c94","contributors":{"authors":[{"text":"Ensign, Scott H.","contributorId":81397,"corporation":false,"usgs":true,"family":"Ensign","given":"Scott H.","affiliations":[],"preferred":false,"id":479726,"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":479724,"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":479725,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fagherazzi, Sergio","contributorId":89282,"corporation":false,"usgs":true,"family":"Fagherazzi","given":"Sergio","affiliations":[],"preferred":false,"id":479727,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Understanding pine life history is critical to both conservation and fire management.\nObjectives - Here I lay out the different pathways of pine life history adaptation and a brief overview of pine evolution and the very significant role that fire has played.\nResults - Pinus originated ~150 Ma in the mid-Mesozoic Era and radiated across the northern continent of Laurasia during the Cretaceous Period. Pines have followed two evolutionary strategies interpreted as responses to competition by the newly emerging angiosperms. The Strobus lineage mostly has radiated into stressful sites of low nutrient soils and extremes in cold or heat. The Pinus (subgenus) lineage has radiated into fire-prone landscapes with diverse fire regimes. Examination of life history traits illustrates syndromes associated with fire-avoider, fire-tolerater, fire-embracer, and fire-refuge strategies.\nConclusion - Understanding the current pattern of pine distribution requires interpreting their evolution in terms of climate, geology, and fire. All three of these factors have played a role since the Mesozoic origin of the genus. All are important to the appropriate management of these resources.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Annals of Forest Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s13595-012-0201-8","usgsCitation":"Keeley, J.E., 2012, Ecology and evolution of pine life histories: Annals of Forest Science, v. 69, no. 4, p. 445-453, https://doi.org/10.1007/s13595-012-0201-8.","productDescription":"9 p.","startPage":"445","endPage":"453","ipdsId":"IP-035829","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":474172,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s13595-012-0201-8","text":"Publisher Index Page"},{"id":272058,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272057,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s13595-012-0201-8"}],"country":"United States","volume":"69","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-05-09","publicationStatus":"PW","scienceBaseUri":"518a2267e4b061e1bd533388","contributors":{"authors":[{"text":"Keeley, Jon E. 0000-0002-4564-6521 jon_keeley@usgs.gov","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":1268,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","email":"jon_keeley@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":472212,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This study explores the complementarity of India's ResourceSat-1 Advanced Wide Field Sensor (AWiFS) with the Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+). The analysis focuses on the comparative radiometry, geometry, and spectral properties of the two sensors. Two applied assessments of these data are also explored to examine the strengths and limitations of these alternate sources of moderate resolution land imagery with specific application domains. There are significant technical differences in these imaging systems including spectral band response, pixel dimensions, swath width, and radiometric resolution which produce differences in observation data sets. None of these differences was found to strongly limit comparable analyses in agricultural and forestry applications. Overall, we found that the AWiFS and Landsat TM/ETM+ imagery are comparable and in some ways complementary, particularly with respect to temporal repeat frequency. We have found that there are limits to our understanding of the AWiFS performance, for example, multi-camera design and stability of radiometric calibration over time, that leave some uncertainty that has been better addressed for Landsat through the Image Assessment System and related cross-sensor calibration studies. Such work still needs to be undertaken for AWiFS and similar observatories that may play roles in the Global Earth Observation System of Systems Land Surface Imaging Constellation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Remote Sensing of Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.rse.2012.03.002","usgsCitation":"Goward, S., Chander, G., Pagnutti, M., Marx, A., Ryan, R., Thomas, N., and Tetrault, R., 2012, Complementarity of ResourceSat-1 AWiFS and Landsat TM/ETM+ sensors: Remote Sensing of Environment, v. 123, p. 41-56, https://doi.org/10.1016/j.rse.2012.03.002.","productDescription":"16 p.","startPage":"41","endPage":"56","ipdsId":"IP-036720","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":271321,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271320,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.rse.2012.03.002"}],"volume":"123","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51751746e4b074c2b05564a3","contributors":{"authors":[{"text":"Goward, S.N.","contributorId":94514,"corporation":false,"usgs":true,"family":"Goward","given":"S.N.","affiliations":[],"preferred":false,"id":473186,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chander, G.","contributorId":51449,"corporation":false,"usgs":true,"family":"Chander","given":"G.","affiliations":[],"preferred":false,"id":473182,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pagnutti, M.","contributorId":69874,"corporation":false,"usgs":true,"family":"Pagnutti","given":"M.","affiliations":[],"preferred":false,"id":473183,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Marx, A.","contributorId":104798,"corporation":false,"usgs":true,"family":"Marx","given":"A.","email":"","affiliations":[],"preferred":false,"id":473188,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ryan, R.","contributorId":85765,"corporation":false,"usgs":true,"family":"Ryan","given":"R.","affiliations":[],"preferred":false,"id":473185,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Thomas, N.","contributorId":72490,"corporation":false,"usgs":true,"family":"Thomas","given":"N.","email":"","affiliations":[],"preferred":false,"id":473184,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Tetrault, R.","contributorId":103956,"corporation":false,"usgs":true,"family":"Tetrault","given":"R.","email":"","affiliations":[],"preferred":false,"id":473187,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}
