The consequences of thiamine deficiency as measured at the egg stage for other important early life stage processes like growth, foraging efficiency, and predator avoidance that may also result in mortality, are unknown. Accordingly, we investigated the impacts of low thiamine on the specific growth rate (SGR) of first‐feeding fry, the ability of first‐feeding fry to capture&nbsp;</span><i>Daphnia</i><span>, fry emergence in the presence of a potential predator (round goby&nbsp;</span><i>Apollina</i><span>&nbsp;(formerly&nbsp;</span><i>Neogobius</i><span>)&nbsp;</span><i>melanostomus</i><span>), and predation by slimy sculpin&nbsp;</span><i>Cottus cognatus</i><span>. We used a combination of thiamine‐deficient and thiamine‐replete wild stocks of lake trout&nbsp;</span><i>Salvelinus namaycush</i><span>&nbsp;for this purpose. From these investigations we developed predictive relationships. Specific growth rate was related to egg thiamine concentration. From the exponential relationship, it was predicted that the threshold egg thiamine concentrations associated with 20% and 50% reductions in SGR are 8.1 and 5.1 nmol/g, respectively. The foraging rate on&nbsp;</span><i>Daphnia</i><span>&nbsp;was also related to egg thiamine concentration by an exponential relationship. It was predicted that the threshold concentrations associated with 20% and 50% reductions in this rate are 6.9 and 2.9 nmol/g, respectively. The presence of a round goby significantly reduced emergence success, but the level of goby predation was unrelated to egg thiamine concentration. Sculpin predation was related, although weakly, to the initial egg thiamine concentration. This research found that thiamine deficiency affected growth, foraging, and predator avoidance in lake trout fry. Growth effects resulting from thiamine deficiency may represent the most sensitive means of monitoring the impact of the secondary consequences of thiamine deficiency. Mortality associated with the combined effects of reduced growth and foraging has the potential to seriously impair lake trout recruitment.</span></p>","language":"English","publisher":"American Fisheries Society","doi":"10.1577/H08-019.1","usgsCitation":"Fitzsimons, J., Brown, S.B., Williston, B., Williston, G., Brown, L.R., Moore, K., Honeyfield, D.C., and Tillitt, D.E., 2009, Influence of thiamine deficiency on Lake Trout larval growth, foraging, and predator avoidance: Journal of Aquatic Animal Health, v. 21, no. 4, p. 302-314, https://doi.org/10.1577/H08-019.1.","productDescription":"13 p.","startPage":"302","endPage":"314","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":358226,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-12-01","publicationStatus":"PW","scienceBaseUri":"5c10cd72e4b034bf6a7f8b67","contributors":{"authors":[{"text":"Fitzsimons, J.D.","contributorId":50845,"corporation":false,"usgs":true,"family":"Fitzsimons","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":747631,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brown, Scott B.","contributorId":175330,"corporation":false,"usgs":false,"family":"Brown","given":"Scott","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":747632,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Williston, B.","contributorId":49176,"corporation":false,"usgs":true,"family":"Williston","given":"B.","email":"","affiliations":[],"preferred":false,"id":747633,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Williston, G.","contributorId":73825,"corporation":false,"usgs":true,"family":"Williston","given":"G.","email":"","affiliations":[],"preferred":false,"id":747634,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Brown, Lisa R.","contributorId":175331,"corporation":false,"usgs":false,"family":"Brown","given":"Lisa","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":747635,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Moore, K.","contributorId":64432,"corporation":false,"usgs":true,"family":"Moore","given":"K.","email":"","affiliations":[],"preferred":false,"id":747636,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Honeyfield, Dale C. 0000-0003-3034-2047 honeyfie@usgs.gov","orcid":"https://orcid.org/0000-0003-3034-2047","contributorId":2774,"corporation":false,"usgs":true,"family":"Honeyfield","given":"Dale","email":"honeyfie@usgs.gov","middleInitial":"C.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":true,"id":747637,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Tillitt, Donald E. 0000-0002-8278-3955 dtillitt@usgs.gov","orcid":"https://orcid.org/0000-0002-8278-3955","contributorId":1875,"corporation":false,"usgs":true,"family":"Tillitt","given":"Donald","email":"dtillitt@usgs.gov","middleInitial":"E.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":747638,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

However, relative to wet deposition, less is known regarding the sources and spatial variability of dry deposition. This is in part due to difficulty in measuring dry deposition and associated deposition velocities. Passive sampling techniques offer potential for improving our understanding of the spatial distribution and sources of gaseous and aerosol N species, referred to here as dry deposition. We report dual nitrate isotopic composition (</span><i>δ</i><sup>15</sup><span>N and&nbsp;</span><i>δ</i><sup>18</sup><span>O) in actively collected dry and wet deposition across the high‐deposition region of Ohio, New York, and Pennsylvania. We also present results from initial tests to examine the efficacy of using passive nitric acid collectors as a collection medium for isotopic analysis at a site in New York. Isotopic values in actively collected dry deposition, including particulate nitrate and gaseous nitric acid, are compared with those in wet nitrate deposition and surrounding NO</span><sub>x</sub><span>&nbsp;emission sources.&nbsp;</span><i>δ</i><sup>15</sup><span>N values in dry and wet fractions are highest at the westernmost sites and lowest at the easternmost sites, and stationary source NO</span><sub>x</sub><span>&nbsp;emissions (e.g., power plants and incinerators) appear to be the primary control on&nbsp;</span><i>δ</i><sup>15</sup><span>N spatial variability. In contrast,&nbsp;</span><i>δ</i><sup>18</sup><span>O values show a less consistent spatial pattern in dry deposition. Both&nbsp;</span><i>δ</i><sup>15</sup><span>N and&nbsp;</span><i>δ</i><sup>18</sup><span>O show strong seasonality, with higher values in winter than summer. Seasonal variations in stationary source NO</span><sub>x</sub><span>emissions appear to be the most likely explanation for seasonal variations in&nbsp;</span><i>δ</i><sup>15</sup><span>N, whereas seasonal variations in air temperature and solar radiation indicate variable chemical oxidation pathways control&nbsp;</span><i>δ</i><sup>18</sup><span>O patterns. Additionally, we demonstrate the utility of passive samplers for collecting the nitric acid (HNO</span><sub>3</sub><span>) component of dry deposition suitable for isotopic analysis. We observe slight differences in&nbsp;</span><i>δ</i><sup>15</sup><span>N‐HNO</span><sub>3</sub><span>values between simultaneous samples collected actively and passively (0.6‰). However, we observe a larger offset in&nbsp;</span><i>δ</i><sup>18</sup><span>O values between actively and passively collected samples; the causes for this offset warrant further investigation. Nonetheless, passive sample collection represents a significant cost savings over active sampling techniques and could allow a more extensive understanding of patterns of dry deposition and associated insights to nitrogen sources across landscapes.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/2008JG000889","usgsCitation":"Elliott, E., Kendall, C., Boyer, E., Burns, D.A., Lear, G., Golden, H., Harlin, K., Bytnerowicz, A., Butler, T., and Glatz, R., 2009, Dual nitrate isotopes in dry deposition: Utility for partitioning NOx source contributions to landscape nitrogen deposition: Journal of Geophysical Research: Biogeosciences, v. 114, no. 4, G04020, https://doi.org/10.1029/2008JG000889.","productDescription":"G04020","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":358222,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"114","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-12-11","publicationStatus":"PW","scienceBaseUri":"5c10cd73e4b034bf6a7f8b6b","contributors":{"authors":[{"text":"Elliott, E.M.","contributorId":78064,"corporation":false,"usgs":true,"family":"Elliott","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":747611,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kendall, Carol 0000-0002-0247-3405 ckendall@usgs.gov","orcid":"https://orcid.org/0000-0002-0247-3405","contributorId":1462,"corporation":false,"usgs":true,"family":"Kendall","given":"Carol","email":"ckendall@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":747612,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Boyer, E.W.","contributorId":56358,"corporation":false,"usgs":false,"family":"Boyer","given":"E.W.","email":"","affiliations":[{"id":6738,"text":"The Pennsylvania State University","active":true,"usgs":false}],"preferred":false,"id":747613,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Burns, Douglas A. 0000-0001-6516-2869 daburns@usgs.gov","orcid":"https://orcid.org/0000-0001-6516-2869","contributorId":1237,"corporation":false,"usgs":true,"family":"Burns","given":"Douglas","email":"daburns@usgs.gov","middleInitial":"A.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":747614,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lear, Gary","contributorId":37362,"corporation":false,"usgs":true,"family":"Lear","given":"Gary","email":"","affiliations":[],"preferred":false,"id":747615,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Golden, H.E.","contributorId":204050,"corporation":false,"usgs":false,"family":"Golden","given":"H.E.","email":"","affiliations":[{"id":36810,"text":"U.S. EPA Office of Research and Development, National Exposure Research Laboratory","active":true,"usgs":false}],"preferred":false,"id":747616,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Harlin, K.","contributorId":107498,"corporation":false,"usgs":true,"family":"Harlin","given":"K.","email":"","affiliations":[],"preferred":false,"id":747617,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Bytnerowicz, A.","contributorId":30027,"corporation":false,"usgs":true,"family":"Bytnerowicz","given":"A.","email":"","affiliations":[],"preferred":false,"id":747618,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Butler, T.J.","contributorId":86973,"corporation":false,"usgs":true,"family":"Butler","given":"T.J.","email":"","affiliations":[],"preferred":false,"id":747619,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Glatz, R.","contributorId":208542,"corporation":false,"usgs":false,"family":"Glatz","given":"R.","email":"","affiliations":[],"preferred":false,"id":747620,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Responses of crocodilians are directly related to suitability of environmental conditions and hydrologic change. Correlations between biological responses and environmental conditions contribute to an understanding of species' status and trends over time. Positive or negative trends of crocodilian populations relative to hydrologic changes permit assessment of positive or negative trends in restoration.</P> \n<br/>\n<p>The crocodilian indicator uses monitoring parameters (performance measures) that have been shown to be both effective and efficient in tracking trends. The alligator component uses relative density (reported as an encounter rate), body condition, and occupancy rates of alligator holes; the crocodile component uses juvenile growth and hatchling survival. We hypothesize that these parameters are correlated with hydrologic conditions including depth, duration, timing, spatial extent and water quality. Salinity is a critical parameter in estuarine habitats. Assessments of parameters defined for crocodilian performance measures support these hypotheses.</p> \n<br/>\n<p>Alligators and crocodiles are the charismatic megafauna of the Everglades. They are both keystone and flagship species to which the public can relate. In addition, the parameters used to track trends are easy to understand. They provide answers to the following questions: How has the number of alligators or crocodiles changed? Are the animals fatter or thinner than they should be? Are the animals in the places (in terms of habitat and geography) where they should be?</p> \n<br/>\n<p>As surely as there is no other Everglades, no other single species defines the Everglades as does the American alligator. The Everglades is the only place in the world where both alligators and crocodiles exist. Crocodilians clearly respond to changes in hydrologic parameters of management interest. These relationships are easy to communicate and mean something to managers, decision makers, and the public. Having crocodilians on the list of system-wide, general indicators provides us with one of the most powerful tools we have to communicate progress of ecosystem restoration in Greater Everglades ecosystems to diverse audiences.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Indicators","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecolind.2008.06.008","issn":"1470160X","usgsCitation":"Mazzotti, F., Best, G.R., Brandt, L., Cherkiss, M.S., Jeffery, B.M., and Rice, K.G., 2009, Alligators and crocodiles as indicators for restoration of Everglades ecosystems: Ecological Indicators, v. 9, no. 6 SUPPL., p.

The objective of this study was to evaluate the distribution, sources and mobilization mechanisms of As in the Southern High Plains (SHP) aquifer, Texas, relative to those in other semiarid, oxidizing systems. Elevated groundwater As levels are widespread in the southern part of the SHP (SHP-S) aquifer, with 47% of wells exceeding the current EPA maximum contaminant level (MCL) of 10&nbsp;μg/L (range 0.3–164&nbsp;μg/L), whereas As levels are much lower in the north (SHP-N: 9%&nbsp;⩾&nbsp;As MCL of 10&nbsp;μg/L; range 0.2–43&nbsp;μg/L). The sharp contrast in As levels between the north and south coincides with a change in total dissolved solids (TDS) from 395&nbsp;mg/L (median north) to 885&nbsp;mg/L (median south). Arsenic is present as arsenate (As V) in this oxidizing system and is correlated with groundwater TDS (Spearman’s </span><i>ρ</i><span>&nbsp;=&nbsp;0.57). The most likely current source of As is sorbed As onto hydrous metal oxides based on correlations between As and other oxyanion-forming elements (V, </span><i>ρ</i><span>&nbsp;=&nbsp;0.88; Se, </span><i>ρ</i><span>&nbsp;=&nbsp;0.54; B, </span><i>ρ</i><span>&nbsp;=&nbsp;0.51 and Mo, </span><i>ρ</i><span>&nbsp;=&nbsp;0.46). This source is similar to that in other oxidizing systems and constitutes a secondary source; the most likely primary source being volcanic ashes in the SHP aquifer or original source rocks in the Rockies, based on co-occurrence of As and F (</span><i>ρ</i><span>&nbsp;=&nbsp;0.56), oxyanion-forming elements and SiO</span><sub>2</sub><span> (</span><i>ρ</i><span>&nbsp;=&nbsp;0.41), which are found in volcanic ashes. High groundwater As concentrations in some semiarid oxidizing systems are related to high evaporation. Although correlation of As with TDS in the SHP aquifer may suggest evaporative concentration, unenriched stable isotopes (δ</span><sup>2</sup><span>H: −65 to −27; δ</span><sup>18</sup><span>O: −9.1 to −4.2) in the SHP aquifer do not support evaporation. High TDS in the SHP aquifer is most likely related to upward movement of saline water from the underlying Triassic Dockum aquifer. Mobilization of As in other semiarid oxidizing systems is caused by increased pH; however, pH in the SHP aquifer is near neutral (10–90 percentiles, 7.0–7.6). Although many processes, such as competitive desorption with SiO</span><sub>2</sub><span>, VO</span><sub>4</sub><span>, or PO</span><sub>4</sub><span>, could be responsible for local mobilization of As in the SHP aquifer, the most plausible explanation for the regional As distribution and correlation with TDS is the counterion effect caused by a change from Ca- to Na-rich, water as shown by the high correlation between As and Na/(Ca)</span><sup>0.5</sup><span> ratios (</span><i>ρ</i><span>&nbsp;=&nbsp;0.57). This change in chemistry is related to mixing with saline water that moves upward from the underlying Dockum aquifer. This counterion effect may mobilize other anions and oxyanion-forming elements that are correlated with As (F, V, Se, B, Mo and SiO</span><sub>2</sub><span>). Competition among the oxyanions for sorption sites may enhance As mobilization. The SHP case study has similar As sources to those of other semiarid, oxidizing systems (original volcanic ash source followed by sorption onto hydrous metal oxides) but contrasts with these systems by showing lack of evaporative concentration and pH mobilization of As but counterion mobilization of As instead in the SHP-S aquifer.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.apgeochem.2009.08.004","usgsCitation":"Scanlon, B., Nicot, J., Reedy, R., Kurtzman, D., Mukherjee, A., and Nordstrom,

The nature of seismic coupling in the gap had been uncertain due to the limited historical record of prior large events and the presence of distinctive upper plate, trench and outer rise structures relative to adjacent regions along the arc that have experienced repeated great interplate earthquakes in the last few centuries. The intraplate region seaward of the seismic gap had several shallow compressional events during the preceding decades (notably an M<sub>S</sub><span>&nbsp;</span>7.2 event on 16 March 1963), leading to speculation that the interplate fault was seismically coupled. This issue was partly resolved by failure of the shallow portion of the interplate megathrust in an M<sub>W</sub><span>&nbsp;</span>= 8.3 thrust event on 15 November 2006. This event ruptured ∼250 km along the seismic gap, just northeast of the great 1963 Kuril Island (M<sub>w</sub><span>&nbsp;</span>= 8.5) earthquake rupture zone. Within minutes of the thrust event, intense earthquake activity commenced beneath the outer wall of the trench seaward of the interplate rupture, with the larger events having normal-faulting mechanisms. An unusual double band of interplate and intraplate aftershocks developed. On 13 January 2007, an M<sub>W</sub><span>&nbsp;</span>= 8.1 extensional earthquake ruptured within the Pacific plate beneath the seaward edge of the Kuril trench. This event is the third largest normal-faulting earthquake seaward of a subduction zone on record, and its rupture zone extended to at least 33 km depth and paralleled most of the length of the 2006 rupture. The 13 January 2007 event produced stronger shaking in Japan than the larger thrust event, as a consequence of higher short-period energy radiation from the source. The great event aftershock sequences were dominated by the expected faulting geometries; thrust faulting for the 2006 rupture zone, and normal faulting for the 2007 rupture zone. A large intraplate compressional event occurred on 15 January 2009 (M<sub>w</sub><span>&nbsp;</span>= 7.4) near 45 km depth, below the rupture zone of the 2007 event and in the vicinity of the 16 March 1963 compressional event. The fault geometry, rupture process and slip distributions of the two great events are estimated using very broadband teleseismic body and surface wave observations. The occurrence of the thrust event in the shallowest portion of the interplate fault in a region with a paucity of large thrust events at greater depths suggests that the event removed most of the slip deficit on this portion of the interplate fault. This great earthquake doublet demonstrates the heightened seismic hazard posed by induced intraplate faulting following large interplate thrust events. Future seismic failure of the remainder of the seismic gap appears viable, with the northeastern region that has also experienced compressional activity seaward of the megathrust warranting particular attention.</p></div></div>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2008JB006280","issn":"01480227","usgsCitation":"Lay, T., Kanamori, H., Ammon, C., Hutko, A.R., Furlong, K., and Rivera, L., 2009, The 2006-2007 Kuril Islands great earthquake sequence: Journal of Geophysical Research B: Solid Earth, v. 114, no. 11, B11308, 31 p., https://doi.org/10.1029/2008JB006280.","productDescription":"B11308, 31 p.","costCenters":[],"links":[{"id":476381,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2008jb006280","text":"Publisher Index Page"},{"id":245007,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"114","issue":"11","noUsgsAuthors":false,"publicationDate":"2009-11-24","publicationStatus":"PW","scienceBaseUri":"505ba64be4b08c986b32101c","contributors":{"authors":[{"text":"Lay, T.","contributorId":49909,"corporation":false,"usgs":true,"family":"Lay","given":"T.","email":"","affiliations":[],"preferred":false,"id":460669,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kanamori, H.","contributorId":55438,"corporation":false,"usgs":true,"family":"Kanamori","given":"H.","affiliations":[],"preferred":false,"id":460670,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ammon, C.J.","contributorId":28389,"corporation":false,"usgs":true,"family":"Ammon","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":460666,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hutko, Alexander R.","contributorId":101788,"corporation":false,"usgs":true,"family":"Hutko","given":"Alexander","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":460671,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Furlong, K.","contributorId":37571,"corporation":false,"usgs":true,"family":"Furlong","given":"K.","affiliations":[],"preferred":false,"id":460667,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Rivera, L.","contributorId":39535,"corporation":false,"usgs":true,"family":"Rivera","given":"L.","email":"","affiliations":[],"preferred":false,"id":460668,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We measured incoming and outgoing sediment across a gradient of soil disturbance (livestock grazing, plowing) and annual plant invasion for 9 years. Our sites included two currently ungrazed sites: one never grazed by livestock and dominated by perennial grasses/well-developed biocrusts and one not grazed since 1974 and dominated by annual weeds with little biocrusts. We used two currently grazed sites: one dominated by annual weeds and the other dominated by perennial plants, both with little biocrusts. Precipitation was highly variable, with years of average, above-average, and extremely low precipitation. During years with average and above-average precipitation, the disturbed sites consistently produced 2.8 times more sediment than the currently undisturbed sites. The never grazed site always produced the least sediment of all the sites. During the drought years, we observed a 5600-fold increase in sediment production from the most disturbed site (dominated by annual grasses, plowed about 50 years previously and currently grazed by livestock) relative to the never grazed site dominated by perennial grasses and well-developed biocrusts, indicating a non-linear, synergistic response to increasing disturbance types and levels. Comparing sediment losses among the sites, biocrusts were most important in predicting site stability, followed by perennial plant cover. Incoming sediment was similar among the sites, and while inputs were up to 9-fold higher at the most heavily disturbed site during drought years compared to average years, the change during the drought conditions was small relative to the large change seen in the sediment outputs. ?? 2009 Elsevier B.V.

Non-hydrostatic pore-fluid pressure is produced by dilatancy, a state-dependent property that links the depth-averaged shear rate and volumetric strain rate of the granular phase. Pore-pressure changes caused by shearing allow the model to exhibit rate-dependent flow resistance, despite the fact that the basal shear traction involves only rate-independent Coulomb friction. An analytical solution of simplified model equations shows that the onset of downslope motion can be accelerated or retarded by pore-pressure change, contingent on whether dilatancy is positive or negative. A different analytical solution shows that such effects will likely be muted if downslope motion continues long enough, because dilatancy then evolves toward zero, and volume fractions and pore pressure concurrently evolve toward steady states. ?? 2009 American Institute of Physics.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"AIP Conference Proceedings","largerWorkSubtype":{"id":15,"text":"Monograph"},"conferenceTitle":"6th International Conference on Micromechanics of Granular Media, Powders and Grains 2009","conferenceDate":"July 13-17, 2009","conferenceLocation":"Golden, CO","language":"English","publisher":"AIP Publishing","doi":"10.1063/1.3180101","issn":"0094243X","isbn":"9780735406827","usgsCitation":"Iverson, R., 2009, Elements of an improved model of debris-flow motion, <i>in</i> AIP Conference Proceedings, v. 1145, Golden, CO, July 13-17, 2009, p. 9-16, https://doi.org/10.1063/1.3180101.","productDescription":"8 p.","startPage":"9","endPage":"16","numberOfPages":"8","ipdsId":"IP-011929","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":245168,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1145","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a08c1e4b0c8380cd51c66","contributors":{"authors":[{"text":"Iverson, R.M. 0000-0002-7369-3819","orcid":"https://orcid.org/0000-0002-7369-3819","contributorId":16435,"corporation":false,"usgs":true,"family":"Iverson","given":"R.M.","affiliations":[],"preferred":false,"id":460984,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We measured the effects of ongoing restoration efforts on wildlife abundance and diversity on one of the largest of these fragments, Fort Funston in the Golden Gate National Recreation Area. Efforts included removal of non-native species, active restoration of native dune vegetation, and restricted visitor use. We collected data regarding the composition and abundance of vegetation, birds, and ground-dwelling vertebrates on four treatments including an actively restored area with restricted visitor use, an unrestored area where visitor use had been restricted for ten years, an unrestored area where visitor use had been restricted for two years, and an unrestored area with unrestricted visitor use. Results indicated that the diversity and abundance of wildlife species, as well as the richness and cover of native plant species, were greater in the restored area than in all other sampled areas. Restricted visitor use alone had only modest positive effects on the abundance and diversity of wildlife and the richness and cover of native plant species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Restoration","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.3368/er.27.4.439","issn":"15434079","usgsCitation":"Russell, W., Shulzitski, J., and Setty, A., 2009, Evaluating wildlife response to coastal dune habitat restoration in san francisco, california: Ecological Restoration, v. 27, no. 4, p. 439-448, https://doi.org/10.3368/er.27.4.439.","startPage":"439","endPage":"448","numberOfPages":"10","costCenters":[],"links":[{"id":245165,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217237,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3368/er.27.4.439"}],"volume":"27","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-11-09","publicationStatus":"PW","scienceBaseUri":"505a0c05e4b0c8380cd529d3","contributors":{"authors":[{"text":"Russell, W.","contributorId":87785,"corporation":false,"usgs":true,"family":"Russell","given":"W.","email":"","affiliations":[],"preferred":false,"id":460964,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shulzitski, J.","contributorId":76578,"corporation":false,"usgs":true,"family":"Shulzitski","given":"J.","email":"","affiliations":[],"preferred":false,"id":460963,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Setty, A.","contributorId":72620,"corporation":false,"usgs":true,"family":"Setty","given":"A.","email":"","affiliations":[],"preferred":false,"id":460962,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In this paper, a statistical approach for assessing uncertainty based on interpolated variance estimation (IVE) is introduced. The IVE method quantifies all sources of random uncertainty in the measured data. This paper presents results employing data from sites where substantial over-sampling allowed for the comparison of IVE-estimated uncertainty and observed variability among repeated measurements. These results suggest that the IVE approach can provide approximate estimates of measurement uncertainty. The use of IVE to estimate the uncertainty of a discharge measurement would provide the hydrographer an immediate determination of uncertainty and help determine whether there is a need for additional sampling in problematic river cross sections. ?? 2009 ASCE.","largerWorkTitle":"Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers","conferenceTitle":"World Environmental and Water Resources Congress 2009: Great Rivers","conferenceDate":"17 May 2009 through 21 May 2009","conferenceLocation":"Kansas City, MO","language":"English","doi":"10.1061/41036(342)599","isbn":"9780784410363","usgsCitation":"Kiang, J., Cohn, T., and Mason, R., 2009, Quantifying uncertainty in discharge measurements: A new approach, <i>in</i> Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers, v. 342, Kansas City, MO, 17 May 2009 through 21 May 2009, p. 5924-5931, https://doi.org/10.1061/41036(342)599.","startPage":"5924","endPage":"5931","numberOfPages":"8","costCenters":[],"links":[{"id":217254,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/41036(342)599"},{"id":245185,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"342","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505a91f0e4b0c8380cd8055f","contributors":{"authors":[{"text":"Kiang, J.E.","contributorId":101058,"corporation":false,"usgs":true,"family":"Kiang","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":459955,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cohn, T.A.","contributorId":84789,"corporation":false,"usgs":true,"family":"Cohn","given":"T.A.","email":"","affiliations":[],"preferred":false,"id":459954,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mason, R.R.","contributorId":34520,"corporation":false,"usgs":true,"family":"Mason","given":"R.R.","affiliations":[],"preferred":false,"id":459953,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Association studies of disease susceptibility in free-ranging populations, however, face considerable challenges including: the need for large sample sizes when disease is rare, animals of unknown pedigree create a risk of spurious results due to population admixture, and the inability to control disease exposure or dose. We used an innovative matched case&ndash;control design and conditional logistic regression to evaluate associations between polymorphisms of complement C1q and prion protein (Prnp) genes and CWD infection in white-tailed deer from the CWD endemic area in south-central Wisconsin.

Cases and controls were also matched on factors (sex, location, age) previously demonstrated to affect CWD infection risk. For Prnp, deer with at least one Serine (S) at amino acid 96 were significantly less likely to be CWD-positive relative to deer homozygous for Glycine (G).

Even if conservative estimates are considered and only a small fraction is recoverable, the sheer size of the resource is so large that it demands evaluation as a potential energy source. In this review paper, we discuss the distribution of natural GH accumulations, the status of the primary international research and development (R&D) programs, and the remaining science and technological challenges facing the commercialization of production. After a brief examination of GH accumulations that are well characterized and appear to be models for future development and gas production, we analyze the role of numerical simulation in the assessment of the hydrate-production potential, identify the data needs for reliable predictions, evaluate the status of knowledge with regard to these needs, discuss knowledge gaps and their impact, and reach the conclusion that the numerical-simulation capabilities are quite advanced and that the related gaps either are not significant or are being addressed. We review the current body of literature relevant to potential productivity from different types of GH deposits and determine that there are consistent indications of a large production potential at high rates across long periods from a wide variety of hydrate deposits. Finally, we identify (a) features, conditions, geology and techniques that are desirable in potential production targets; (b) methods to maximize production; and (c) some of the conditions and characteristics that render certain GH deposits undesirable for production.

Chemical compositions and magnetic properties of the soil samples are similar among sites relative to dust sources, geographic areas, and lithologic substrates. Exceptions are Li, U, and W, enriched in Owens Valley, California, and Mg and Sr, enriched in soils formed on calcareous fan gravel in southeast Nevada. The Av horizons are dominated by dust and reflect limited mixing with substrate sediments. Modern dust samples are also similar across the region, except that Owens Valley dusts are higher in Mg, Ba, and Li and dusts both there and at sites to the north on volcanic substrates are higher in Sb and W. Thus, dust and Av horizons consist of contributions from many different sources that are well mixed before deposition. Modern dusts contain significantly greater amounts of As, Cd, Cr, Cu, Ni, Pb, and Sb than do Av horizons, which record dust additions over hundreds to thousands of years. These results suggest that modern dust compositions are influenced by anthropogenic sources and emissions from Owens (dry) Lake after its artificial desiccation in 1926. Both modern dusts and Av horizons are enriched in As, Ba, Cu, Li, Sb, Th, U, and W relative to average crustal composition, which we interpret to indicate that the geologic sources of dust in the southwestern United States are geochemically distinctive.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research F: Earth Surface","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AGU","publisherLocation":"Washington, D.C.","doi":"10.1029/2008JF001009","issn":"01480227","usgsCitation":"Reheis, M., Budahn, J., Lamothe, P.J., and Reynolds, R.L., 2009, Compositions of modern dust and surface sediments in the Desert Southwest, United States: Journal of Geophysical Research F: Earth Surface, v. 114, no.

To ensure timely and relevant data, it is important to update this base to a more recent time period. A prototype method was developed to update the land cover and impervious surface by individual Landsat path and row. This method updates NLCD 2001 to a nominal date of 2006 by using both Landsat imagery and data from NLCD 2001 as the baseline. Pairs of Landsat scenes in the same season from both 2001 and 2006 were acquired according to satellite paths and rows and normalized to allow calculation of change vectors between the two dates. Conservative thresholds based on Anderson Level I land cover classes were used to segregate the change vectors and determine areas of change and no-change. Once change areas had been identified, impervious surface was estimated for areas of change by sampling from NLCD 2001 in unchanged areas. Methods were developed and tested across five Landsat path/row study sites that contain a variety of metropolitan areas. Results from the five study areas show that the vast majority of impervious surface changes associated with urban developments were accurately captured and updated. The approach optimizes mapping efficiency and can provide users a flexible method to generate updated impervious surface at national and regional scales.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"2009 Joint urban remote sensing event","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"2009 Joint Urban Remote Sensing Event","conferenceDate":"may 20-22, 2009","conferenceLocation":"Shanghai, China","language":"English","publisher":"IEEE","doi":"10.1109/URS.2009.5137597","usgsCitation":"Xian, G.Z., and Homer, C.G., 2009, Monitoring urban land cover change by updating the national land cover database impervious surface products, <i>in</i> 2009 Joint urban remote sensing event, Shanghai, China, may 20-22, 2009, p. 1-5, https://doi.org/10.1109/URS.2009.5137597.","productDescription":"5 p.","startPage":"1","endPage":"5","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":245029,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5dfae4b0c8380cd70713","contributors":{"authors":[{"text":"Xian, George Z. 0000-0001-5674-2204 xian@usgs.gov","orcid":"https://orcid.org/0000-0001-5674-2204","contributorId":2263,"corporation":false,"usgs":true,"family":"Xian","given":"George","email":"xian@usgs.gov","middleInitial":"Z.","affiliations":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":459916,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Homer, Collin G. 0000-0003-4755-8135 homer@usgs.gov","orcid":"https://orcid.org/0000-0003-4755-8135","contributorId":2262,"corporation":false,"usgs":true,"family":"Homer","given":"Collin","email":"homer@usgs.gov","middleInitial":"G.","affiliations":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true},{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":459915,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Without standardization, differences among collections can be partially attributed to disparities in electrofishing methodology, intensity of the electrical field, and size of the electrical field rather than to disparities in fish abundance, population structure, or fish community composition. Such standardization is critical when electrofishing is used to monitor temporal and spatial changes of fish assemblages in waters with diverse ambient conductivities. In a field study, standardization improved predictability of electrofishing catch rates by about 15% (Burkhardt and Gutreuter 1995). In a laboratory study, standardization of power transfer allowed scientists accurate prediction of control unit settings required to immobilize fish in a wide range of ambient conductivities (Miranda and Dolan 2003). Because electrofishing is an active capture method applied to changing microenvironments that continually distort the electric field and to multiple target species that respond&nbsp;differently to electric fields, complete standardization is not possible with present technology, but standardization of controllable power transferred to fish is advisable.</p>\n<p>Standardizing boat electrofishing entails achieving an accepted level of collection consistency by managing various brand factors, including (1) the temporal and spatial distribution of sampling effort, (2) boat operation, (3) equipment configuration, (4) characteristics of the waveform and energized field, and (5) power transferred to fish. This chapter focuses exclusively on factor 5:L factors 1-4 have been addressed in earlier chapters. Additionally, while the concepts covered in this chapter address boat electrofishing in general, the power settings discussed were developed from tests with primarily warmwater fish communities. Others (see Chapter 9) recommend lower power settings for communities consisting of primarily coldwater fishes. For reviews of basic concepts of electricity, electrofishing theory and systems, fish behavior relative to diverse waveforms, and injury matter, the reader is referred to Novotny (1990), Reynold (1996), and Snyder (2003).</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Standard methods for sampling North American freshwater fishes","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"American Fisheries Society","publisherLocation":"Bethesda, MD","doi":"10.47886/9781934874103.ch14","usgsCitation":"Miranda, L., 2009, Standardizing electrofishing power for boat electrofishing: chapter 14, chap. <i>of</i> Standard methods for sampling North American freshwater fishes, p. 223-230, https://doi.org/10.47886/9781934874103.ch14.","productDescription":"8 p.","startPage":"223","endPage":"230","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":393,"text":"Mississippi Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":275546,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51f78eebe4b02e26443a93b9","contributors":{"editors":[{"text":"Bonar, Scott A. 0000-0003-3532-4067 sbonar@usgs.gov","orcid":"https://orcid.org/0000-0003-3532-4067","contributorId":3712,"corporation":false,"usgs":true,"family":"Bonar","given":"Scott","email":"sbonar@usgs.gov","middleInitial":"A.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":509435,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Hubert, Wayne A.","contributorId":9325,"corporation":false,"usgs":true,"family":"Hubert","given":"Wayne","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":509436,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Willis, David W.","contributorId":55313,"corporation":false,"usgs":true,"family":"Willis","given":"David","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":509437,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Miranda, L.E.","contributorId":64132,"corporation":false,"usgs":true,"family":"Miranda","given":"L.E.","email":"","affiliations":[],"preferred":false,"id":481631,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In this study, the potential of the synergistic use of optical and InSAR data in urban impervious surface mapping at the sub‐pixel level was investigated. A case study in Hong Kong was conducted for this purpose by applying a classification and regression tree (CART) algorithm to SPOT 5 multispectral imagery and ERS‐2 SAR data. Validated by reference data derived from high‐resolution colour‐infrared (CIR) aerial photographs, our results show that the addition of InSAR feature information can improve the estimation of impervious surface percentage (ISP) in comparison with using SPOT imagery alone. The improvement is especially notable in separating urban impervious surface from the vacant land/bare ground, which has been a difficult task in ISP modelling with optical remote sensing data. In addition, the results demonstrate the potential to map urban impervious surface by using InSAR data alone. This allows frequent monitoring of world's cities located in cloud‐prone and rainy areas.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/01431160802555838","issn":"01431161","usgsCitation":"Jiang, L., Liao, M., Lin, H., and Yang, L., 2009, Synergistic use of optical and InSAR data for urban impervious surface mapping: A case study in Hong Kong: International Journal of Remote Sensing, v. 30, no. 11, p. 2781-2796, https://doi.org/10.1080/01431160802555838.","productDescription":"16 p.","startPage":"2781","endPage":"2796","numberOfPages":"16","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":245036,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217119,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/01431160802555838"}],"volume":"30","issue":"11","noUsgsAuthors":false,"publicationDate":"2009-06-22","publicationStatus":"PW","scienceBaseUri":"505ba340e4b08c986b31fc2b","contributors":{"authors":[{"text":"Jiang, L.","contributorId":107530,"corporation":false,"usgs":true,"family":"Jiang","given":"L.","email":"","affiliations":[],"preferred":false,"id":460369,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liao, M.","contributorId":86600,"corporation":false,"usgs":true,"family":"Liao","given":"M.","email":"","affiliations":[],"preferred":false,"id":460368,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lin, H.","contributorId":17854,"corporation":false,"usgs":true,"family":"Lin","given":"H.","email":"","affiliations":[],"preferred":false,"id":460367,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Yang, L.","contributorId":6200,"corporation":false,"usgs":true,"family":"Yang","given":"L.","affiliations":[],"preferred":false,"id":460366,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
