The two PSH models are constructed with similar methodologies and data. Our comparisons show a tendency for the PSH models to slightly exceed the historical hazard in New Zealand and westernmost continental United States interplate regions, but show lower hazard than that of the historical record in the continental United States intraplate region. Factors such as non-Poissonian behavior, parameterization of active fault data in the PSH calculations, and uncertainties in estimation of ground-motion levels from historical felt intensity data for the interplate regions may have led to the higher-than-historical levels of hazard at the interplate sites. In contrast, the less-than-historical hazard for the remaining continental United States (intraplate) sites may be largely due to site conditions not having been considered at the intraplate sites, and uncertainties in correlating ground-motion levels to historical felt intensities. The study also highlights the importance of evaluating PSH models at more than one region, because the conclusions reached on the basis of a solely interplate or intraplate study would be very different.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120050176","issn":"00371106","usgsCitation":"Stirling, M.W., and Petersen, M.D., 2006, Comparison of the historical record of earthquake hazard with seismic-hazard models for New Zealand and the continental United States: Bulletin of the Seismological Society of America, v. 96, no. 6, p. 1978-1994, https://doi.org/10.1785/0120050176.","startPage":"1978","endPage":"1994","numberOfPages":"17","costCenters":[],"links":[{"id":209663,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120050176"},{"id":236332,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"96","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f8ace4b0c8380cd4d204","contributors":{"authors":[{"text":"Stirling, Mark W.","contributorId":175118,"corporation":false,"usgs":false,"family":"Stirling","given":"Mark","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":419296,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Petersen, Mark D. 0000-0001-8542-3990 mpetersen@usgs.gov","orcid":"https://orcid.org/0000-0001-8542-3990","contributorId":1163,"corporation":false,"usgs":true,"family":"Petersen","given":"Mark","email":"mpetersen@usgs.gov","middleInitial":"D.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":419297,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We parameterized stage-based population models that incorporated density dependence and seed dormancy with data from a 5.5-year experiment that quantified how granivorous mice and herbivorous voles influence bush lupine (Lupinus arboreus) demography. We asked how seed dormancy and density-dependent seedling survival mediate the impacts of these consumers in dune and grassland habitats. In dune habitat, mice reduced analytical ?? (the intrinsic rate of population growth) by 39%, the equilibrium number of above-ground plants by 90%, and the seed bank by 98%; voles had minimal effects. In adjacent grasslands, mice had minimal effects, but seedling herbivory by voles reduced analytical ?? by 15% and reduced both the equilibrium number of aboveground plants and dormant seeds by 63%. A bootstrap analysis demonstrated that these consumer effects were robust to parameter uncertainty. Our results demonstrate that the quantitative strengths of seed dormancy and density-dependent seedling survival-not their mere existence-critically mediate consumer effects. This study suggests that plant population dynamics and distribution may be more strongly influenced by consumers of seeds and seedlings than is currently recognized. ?? 2006 by The University of Chicago.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1086/507877","issn":"00030147","usgsCitation":"Kauffman, M.J., and Maron, J., 2006, Consumers limit the abundance and dynamics of a perennial shrub with a seed bank: American Naturalist, v. 168, no. 4, p. 454-470, https://doi.org/10.1086/507877.","startPage":"454","endPage":"470","numberOfPages":"17","costCenters":[],"links":[{"id":209933,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1086/507877"},{"id":236693,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"168","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fa23e4b0c8380cd4d954","contributors":{"authors":[{"text":"Kauffman, M.

At these depths, seismic velocity models, constrained by body-and surface-wave continent-scale tomography, are compared with mantle temperatures and mantle gravity anomalies.

A survey of water quality indicated that selenium and other contaminants may be of concern at Goshen Warm Springs. We conducted an ecotoxicological study with three objectives: (1) to determine the growth rates of juvenile June suckers in two ponds (Lily Pond and North Pond) at Goshen Warm Springs and in Utah Lake, (2) to determine the uptake and depuration rates of selenium in juvenile June suckers, and (3) to evaluate limnological factors that may influence growth and selenium accumulation in June suckers. Fish growth was significantly greater at Utah Lake and North Pond than at Lily Pond or under current hatchery conditions. At the end of the uptake phase of the study (day 87), selenium concentrations in June suckers from Lily Pond, North Pond, and Utah Lake were 1.62, 1.90, and 1.32 <span>μg</span>/g of dry weight, respectively. Selenium uptake in June suckers was statistically significant at Lily Pond (<span>0.005 μg</span><strong>·</strong><span>g</span><sup>−1</sup> <strong>·</strong><span>d</span><sup>−1</sup>), North Pond (0.010 <span>μg</span><strong>·</strong><span>g</span><sup>−1</sup> <strong>·</strong><span>d</span><sup>−1</sup>), and Utah Lake (0.003 <span>μg</span><strong>·</strong><span>g</span><sup>−1</sup> <strong>·</strong><span>d</span><sup>−1</sup>). At day 87, the fish were transferred to well water for selenium depuration. Significant selenium depuration occurred after the transfer of June suckers to clean water. Results indicated that selenium bioaccumulated to statistically significant levels at both Lily and North ponds.

There, SRP levels can be naturally high due to groundwater enriched by geothermal activity within the surfically dormant volcanic landscape, and subsequently discharged at ambient temperature. Combined field and laboratory approaches simulated high but natural geothermal SRP input with the objective of estimating the magnitude of amended SRP retention within high and low SRP settings and determining the underlying mechanisms of SRP retention. First, we examined short-term SRP retention/transport using combined SRP-conservative tracer additions at high natural in situ concentrations. Second, we attempted to observe a DIN response during SRP amendment as an indicator of biological uptake. Third, we determined SRP release/retention using laboratory sediment assays under control and biologically inhibited conditions. Short-term in situ tracer-SRP additions indicated retention in both naturally high and low SRP reaches. Retention of added SRP mass in Upper Salto (low SRP) was 17% (7.5 mg-P m-2 h-1), and 20% (10.9 mg-P m-2 h -1) in Lower Salto (high SRP). No DIN response in either nitrate or ammonium was observed. Laboratory assays using fresh Lower Salto sediments indicated SRP release (15.4 ?? 5.9 ??g-P g dry wt.-1 h -1), when incubated in filter sterilized Salto water at ambient P concentration, but retention when incubated in filter sterilized river water amended to 2.0 mg SRP l-1 (233.2 ?? 5.8 ??g-P g dry wt. -1 h-1). SRP uptake/release was similar in both control- and biocide-treated sediments indicating predominantly abiotic retention. High SRP retention even under biologically saturated conditions, absence of a DIN response to amendment, patterns of desorption following amendment, and similar patterns of retention and release under control and biologically inhibited conditions all indicated predominantly abiotic P flux. ?? 2006 Springer Science+Business Media, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biogeochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10533-006-9048-0","issn":"01682563","usgsCitation":"Triska, F., Pringle, C.M., Duff, J., Avanzino, R., and Zellweger, G., 2006, Soluble reactive phosphorus (SRP) transport and retention in tropical, rain forest streams draining a volcanic landscape in Costa Rica: In situ SRP amendment to streams and laboratory studies: Biogeochemistry, v. 81, no. 2, p. 145-157, https://doi.org/10.1007/s10533-006-9048-0.","startPage":"145","endPage":"157","numberOfPages":"13","costCenters":[],"links":[{"id":209930,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10533-006-9048-0"},{"id":236690,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"2","noUsgsAuthors":false,"publicationDate":"2006-10-03","publicationStatus":"PW","scienceBaseUri":"505b924ae4b08c986b319e03","contributors":{"authors":[{"text":"Triska, F.","contributorId":70173,"corporation":false,"usgs":true,"family":"Triska","given":"F.","email":"","affiliations":[],"preferred":false,"id":419919,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pringle, C.

In many circumstances, simpler models are characterized by fewer defined parameters and shorter execution times. In this work, the number of parameters is used as the primary measure of simplicity and complexity; the advantages of shorter execution times also are considered. The ideas are presented in the context of constructing ground water models but are applicable to many fields. Simplicity first is put in perspective as part of the entire modeling process using 14 guidelines for effective model calibration. It is noted that neither very simple nor very complex models generally produce the most accurate predictions and that determining the appropriate level of complexity is an ill-defined process. It is suggested that a thorough evaluation of observation errors is essential to model development. Finally, specific ways are discussed to design useful ground water models that have fewer parameters and shorter execution times.","largerWorkTitle":"Ground Water","language":"English","doi":"10.1111/j.1745-6584.2006.00227.x","issn":"0017467X","usgsCitation":"Hill, M.C., 2006, The practical use of simplicity in developing ground water models, <i>in</i> Ground Water, v. 44, no. 6, p. 775-781, https://doi.org/10.1111/j.1745-6584.2006.00227.x.","startPage":"775","endPage":"781","numberOfPages":"7","costCenters":[],"links":[{"id":209931,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2006.00227.x"},{"id":236691,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"6","noUsgsAuthors":false,"publicationDate":"2006-05-26","publicationStatus":"PW","scienceBaseUri":"505baec0e4b08c986b3242f1","contributors":{"authors":[{"text":"Hill, M.

We also compared mortality rates and potential outcomes of various management regimes (minimum length limits [MLLs]) among the populations. Total length-log10(age) regression slopes for introduced fish were higher than those for native fish, and von Bertalanffy growth coefficients (K) were greater for introduced fish (Ocmulgee: 0.195; Satilla: 0.201) than for native individuals (Coosa: 0.057; Tallapoosa: 0.059). Therefore, introduced flathead catfish grew more rapidly than those in their native range. Mortality (instantaneous mortality rate, Z) was higher in the Satilla River population (Z = -0.602) than in the Ocmulgee River (Z = -0.227) and Coosa River (Z = -0.156) populations. However, fish in the Satilla River population had been introduced for only 10 years and presumably did not reach their theoretical maximum age, potentially biasing the mortality estimate for that population. Simulation of management regimes in Fishery Analyses and Simulation Tools software predicted that maximum biomass of flathead catfish in the Ocmulgee (1,668 kg) and Satilla (1,137 kg) rivers was substantially larger than that in the Coosa (873 kg) and Tallapoosa (768 kg) populations. However, increased exploitation rates in the Ocmulgee and Satilla River populations resulted in dramatic declines in overall biomass, especially at lower MLLs (254 and 356 mm, respectively). Therefore, in systems where introduced flathead catfish represent an important recreational fishery but have dramatically reduced the abundance of native fishes through predation, minimal protection is recommended. We contend that rapid growth of introduced flathead catfish has major implications for their management and the conservation of native fishes. ??

The objective of this study was to quantify protozoa associated with biological soil crusts and test the response of protozoa to increased temperature and precipitation as is predicted by some global climate models. Protozoa were more abundant when associated with cyanobacteria/lichen crusts than with cyanobacteria crusts alone. Amoebae, flagellates, and ciliates originating from the Colorado Plateau desert (cool desert, primarily winter precipitation) declined 50-, 10-, and 100-fold, respectively, when moved in field mesocosms to the Chihuahuan Desert (hot desert, primarily summer rain). However, this was not observed in protozoa collected from the Chihuahuan Desert and moved to the Sonoran desert (hot desert, also summer rain, but warmer than Chihuahuan Desert). Protozoa in culture began to encyst at 37??C. Cysts survived the upper end of daily temperatures (37-55??C), and could be stimulated to excyst if temperatures were reduced to 15??C or lower. Results from this study suggest that cool desert protozoa are influenced negatively by increased summer precipitation during excessive summer temperatures, and that desert protozoa may be adapted to a specific desert's temperature and precipitation regime. ?? 2006 by the International Society of Protistologists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Eukaryotic Microbiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1550-7408.2006.00134.x","issn":"10665234","usgsCitation":"Darby, B., Housman, D., Zaki, A., Shamout, Y., Adl, S., Belnap, J., and Neher, D., 2006, Effects of altered temperature and precipitation on desert protozoa associated with biological soil crusts: Journal of Eukaryotic Microbiology, v. 53, no. 6, p. 507-514, https://doi.org/10.1111/j.1550-7408.2006.00134.x.","startPage":"507","endPage":"514","numberOfPages":"8","costCenters":[],"links":[{"id":209671,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1550-7408.2006.00134.x"},{"id":236343,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"53","issue":"6","noUsgsAuthors":false,"publicationDate":"2006-10-17","publicationStatus":"PW","scienceBaseUri":"505a0685e4b0c8380cd512a3","contributors":{"authors":[{"text":"Darby, B.J.","contributorId":29186,"corporation":false,"usgs":true,"family":"Darby","given":"B.J.","email":"","affiliations":[],"preferred":false,"id":419988,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Housman, D.C.","contributorId":6236,"corporation":false,"usgs":true,"family":"Housman","given":"D.C.","affiliations":[],"preferred":false,"id":419986,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zaki, A.M.","contributorId":59606,"corporation":false,"usgs":true,"family":"Zaki","given":"A.M.","email":"","affiliations":[],"preferred":false,"id":419990,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shamout, Y.","contributorId":52379,"corporation":false,"usgs":true,"family":"Shamout","given":"Y.","email":"","affiliations":[],"preferred":false,"id":419989,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Adl, S.M.","contributorId":76530,"corporation":false,"usgs":true,"family":"Adl","given":"S.M.","email":"","affiliations":[],"preferred":false,"id":419991,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Belnap, J. 0000-0001-7471-2279","orcid":"https://orcid.org/0000-0001-7471-2279","contributorId":23872,"corporation":false,"usgs":true,"family":"Belnap","given":"J.","affiliations":[],"preferred":false,"id":419987,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Neher, D.A.","contributorId":93683,"corporation":false,"usgs":true,"family":"Neher","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":419992,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Orbital reflectance spectra obtained by Mars Express OMEGA over this region are dominated by pyroxene, plagioclase feldspar, crystalline hematite (i.e., concretions), and nano‐phase iron oxide dust signatures, consistent with Pancam and Mini‐TES observations. Mössbauer Spectrometer observations indicate more olivine than observed with the other instruments, consistent with preferential optical obscuration of olivine features in mixtures with pyroxene and dust. Orbital data covering bright plains located several kilometers to the south of the landing site expose a smaller areal abundance of hematite, more dust, and a larger areal extent of outcrop compared to plains proximal to the landing site. Low‐albedo, low‐thermal‐inertia, windswept plains located several hundred kilometers to the south of the landing site are predicted from OMEGA data to have more hematite and fine‐grained olivine grains exposed as compared to the landing site. Low calcium pyroxene dominates spectral signatures from the cratered highlands to the south of Opportunity. A regional‐scale model is presented for the formation of the plains explored by Opportunity, based on a rising ground water table late in the Noachian Era that trapped and altered local materials and aeolian basaltic sands. Cessation of this aqueous process led to dominance of aeolian processes and formation of the current configuration of the plains.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research E: Planets","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2006JE002728","issn":"01480227","usgsCitation":"Arvidson, R., Poulet, F., Morris, R., Bibring, J., Bell, J., Squyres, S.W., Christensen, P.R., Bellucci, G., Gondet, B., Ehlmann, B., Farrand, W.H., Fergason, R., Golombeck, M., Griffes, J., Grotzinger, J., Guinness, E., Herkenhoff, K.E., Johnson, J.R., Klingelhofer, G., Langevin, Y., Ming, D., Seelos, K., Sullivan, R., Ward, J., Wiseman, S., and Wolff, M., 2006, Nature and origin of the hematite-bearing plains of Terra Meridiani based on analyses of orbital and Mars Exploration rover data sets: Journal of Geophysical Research E: Planets, v. 111, no.

Ninety-two females with functional transmitters returned to the Yukon Delta in the spring after they were marked, and we located the nests of 35 of these individuals. Prelaying intervals were influenced by when snow melted in the spring and individual arrival dates on the Yukon Delta. The median prelaying interval was 15 days (range = 12-19 days) in a year when snow melted relatively late, and 11 days (range = 4-16 days) in two warmer years when snow melted earlier. In years when snow melted earlier, prelaying intervals of <12 days for 11 of 15 females suggested they initiated rapid follicle development on spring staging areas. The prelaying interval declined by approximately 0.4 days and nest initiation date increased approximately 0.5 days for each day a female delayed her arrival. Thus, females that arrived first on the Yukon Delta had prelaying intervals up to four days longer, yet they nested up to five days earlier, than females that arrived last. The proximity of spring staging areas on the Alaska Peninsula to nesting areas on the Yukon Delta may enable Emperor Geese to alter timing of follicle development depending on annual conditions, and to invest nutrients acquired from both areas in eggs during their formation. Plasticity in timing of follicle development is likely advantageous in a variable environment where melting of snow cover in the spring can vary by 2-3 weeks annually. ??

Denitrification activities ranged from 0 and 800 ng-N gsed-1 d-1 with large variations observed within short distances (<50 m) along stream reaches. A log-normal probability distribution described the range in denitrification activities and was used to define low (16% of the probability distributibn), medium (68%), and high (16%) denitrification potential groups. Denitrifying bacteria were quantified using a competitive polymerase chain reaction (cPCR) technique that amplified the nirK gene that encodes for nitrite reductase. Results showed a range of nirK quantities from 103 to 107 gene-copy-number gsed.-1 A nonparametric statistical test showed no significant difference in nirK quantifies among stream reaches, but revealed that samples with a high denitrification potential had significantly higher nirK quantities. Denitrification activity was positively correlated with nirK quantities with scatter in the data that can be attributed to varying environmental conditions along stream reaches. Dimensional analysis was used to evaluate denitrification activities according to environmental variables that describe fluid-flow properties, nitrate and organic material quantities, and dissolved oxygen flux. Buckingham's pi theorem was used to generate dimensionless groupings and field data were used to determine scaling parameters. The resulting expressions between dimensionless NO3- flux and dimensionless groupings of environmental variables showed consistent scaling, which indicates that the subreach variability in denitrification rates can be predicted by the controlling physical, chemical, and microbiological conditions.

Health‐based screening levels (HBSLs) were developed collaboratively to supplement existing drinking‐water standards and guidelines as part of a six‐year, multi‐agency pilot study. The pilot study focused on ground water samples collected prior to treatment or blending in areas of New Jersey where groundwater is the principal source of drinking water. This article describes how HBSLs were developed and demonstrates the use of HBSLs as a tool for evaluating water‐quality data in a human‐health context. HBSLs were calculated using standard U.S. Environmental Protection Agency (USEPA) methodologies and toxicity information. New HBSLs were calculated for 12 of 32 contaminants without existing USEPA drinking‐water standards or guidelines, increasing the number of unregulated contaminants (those without maximum contaminant levels (MCLs)) with human‐health benchmarks. Concentrations of 70 of the 78 detected contaminants with human‐health benchmarks were less than MCLs or HBSLs, including all 12 contaminants with new HBSLs, suggesting that most contaminant concentrations were not of potential human‐health concern. HBSLs were applied to a state‐scale groundwater data set in this study, but HBSLs also may be applied to regional and national evaluations of water‐quality data. HBSLs fulfill a critical need for federal, state, and local agencies, water utilities, and others who seek tools for evaluating the occurrence of contaminants without drinking‐water standards or guidelines.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1539-6924.2006.00805.x","issn":"02724332","usgsCitation":"Toccalino, P.L., and Norman, J.E., 2006, Health-based screening levels to evaluate U.S. Geological Survey ground water quality data: Risk Analysis, v. 26, no. 5, p. 1339-1348, https://doi.org/10.1111/j.1539-6924.2006.00805.x.","productDescription":"10 p.","startPage":"1339","endPage":"1348","costCenters":[],"links":[{"id":237261,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210365,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1539-6924.2006.00805.x"}],"volume":"26","issue":"5","noUsgsAuthors":false,"publicationDate":"2006-10-16","publicationStatus":"PW","scienceBaseUri":"505a2fe3e4b0c8380cd5d18f","contributors":{"authors":[{"text":"Toccalino, Patricia L. 0000-0003-1066-1702 ptocca@usgs.gov","orcid":"https://orcid.org/0000-0003-1066-1702","contributorId":933,"corporation":false,"usgs":true,"family":"Toccalino","given":"Patricia","email":"ptocca@usgs.gov","middleInitial":"L.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":false,"id":416556,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Norman, Julia E. 0000-0002-2820-6225 jnorman@usgs.gov","orcid":"https://orcid.org/0000-0002-2820-6225","contributorId":3832,"corporation":false,"usgs":true,"family":"Norman","given":"Julia","email":"jnorman@usgs.gov","middleInitial":"E.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":416555,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Variations in intensity of SEM-CL can be used to distinguish among quartz from superimposed mineralization events in a single vein. In this study, we present a technique to quantify the cathodoluminescent intensity of quartz within individual and among multiple samples to relate luminescence intensity to specific mineralizing events. This technique has been applied to plutonic quartz and three generations of hydrothermal veins at the porphyry copper deposit in Butte, Montana. Analyzed veins include early quartz-molybdenite veins with potassic alteration, pyrite-quartz veins with sericitic alteration, and Main Stage veins with intense sericitic alteration. CL intensity of quartz is diagnostic of each mineralizing event and can be used to fingerprint quartz and its fluid inclusions, isotopes, trace elements, etc., from specific mineralizing episodes. Furthermore, CL intensity increases proportional to temperature of quartz formation, such that plutonic quartz from the Butte quartz monzonite (BQM) that crystallized at temperatures near 750 ??C luminesces with the highest intensity, whereas quartz that precipitated at ???250 ??C in Main Stage veins luminesces with the least intensity. Trace-element analyses via electron microprobe and laser ablation-ICP-MS indicate that plutonic quartz and each generation of hydrothermal quartz from Butte is dominated by characteristic trace amounts of Al, P, Ti, and Fe. Thus, in addition to CL intensity, each generation of quartz can be distinguished based on its unique trace-element content. Aluminum is generally the most abundant element in all generations of quartz, typically between 50 and 200 ppm, but low-temperature, Main Stage quartz containing 400 to 3600 ppm Al is enriched by an order of magnitude relative to all other quartz generations. Phosphorous is present in abundances between 25 and 75 ppm, and P concentrations in quartz show little variation among quartz generations. Iron is the least abundant of these elements in most quartz types and is slightly enriched in CL-dark quartz in pyrite-quartz veins with sericitic alteration. Titanium is directly correlated with both temperature of quartz precipitation, and intensity of quartz luminescence, such that BQM quartz contains hundreds of ppm Ti, whereas Main Stage quartz contains less than 10 ppm Ti. Our results suggest that Ti concentration in quartz is controlled by temperature of quartz precipitation and that increased Ti concentrations in quartz may be responsible for increased CL intensities.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Mineralogist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2138/am.2006.1984","issn":"0003004X","usgsCitation":"Rusk, B., Reed, M., Dilles, J., and Kent, A., 2006, Intensity of quartz cathodoluminescence and trace-element content in quartz from the porphyry copper deposit at Butte, Montana: American Mineralogist, v. 91, no. 8-9, p. 1300-1312, https://doi.org/10.2138/am.2006.1984.","startPage":"1300","endPage":"1312","numberOfPages":"13","costCenters":[],"links":[{"id":237020,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210178,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2138/am.2006.1984"}],"volume":"91","issue":"8-9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3c9ae4b0c8380cd62ea1","contributors":{"authors":[{"text":"Rusk, B.G.","contributorId":48667,"corporation":false,"usgs":true,"family":"Rusk","given":"B.G.","affiliations":[],"preferred":false,"id":416804,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reed, M.H.","contributorId":91606,"corporation":false,"usgs":true,"family":"Reed","given":"M.H.","email":"","affiliations":[],"preferred":false,"id":416806,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dilles, J.H.","contributorId":25310,"corporation":false,"usgs":true,"family":"Dilles","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":416803,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kent, A.J.R.","contributorId":76123,"corporation":false,"usgs":true,"family":"Kent","given":"A.J.R.","email":"","affiliations":[],"preferred":false,"id":416805,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We determined the feasibility of the analytical method developed by Royle and Nichols (2003), which uses presence-absence (detection-non-detection) field data, to estimate abundance of Mountain Plovers (Charadrius montanus) per sampling unit in agricultural fields, grassland, and prairie dog habitat in eastern Colorado. Field methods were easy to implement and results suggest that the analytical method provides valuable insight into population patterning among habitats. Mountain Plover abundance was highest in prairie dog habitat, slightly lower in agricultural fields, and substantially lower in grassland.

We documented changes in lipid, protein, moisture, and ash in body tissues of adult female Pacific Black Brant (Branta bernicla nigricans) and modeled the energetic costs of wintering. Birds were collected at the extremes of their winter range, in Alaska and Baja California, Mexico. Body lipids decreased over winter for birds in Alaska but increased for those in Baja California. Conversely, body protein increased over winter for Brant in Alaska and remained stable for birds in Baja California. Lipid stores likely fuel migration for Brant wintering in Baja California and ensure winter survival for those in Alaska. Increases in body protein may support earlier reproduction for Brant in Alaska. Predicted energy demands were similar between sites during late winter but avenues of expenditure were different. Birds in Baja California spent more energy on lipid synthesis while those in Alaska incurred higher thermoregulatory costs. Estimated daily intake rates of eelgrass were similar between sites in early winter; however, feeding time was more constrained in Alaska because of high tides and short photoperiods. Despite differences in energetic costs and foraging time, Brant wintering at both sites appeared to be in good condition. We suggest that wintering in Alaska may be more advantageous than long-distance migration if winter survival is similar between sites and constraints on foraging time do not impair body condition. ??

In the mountainous West and other similar areas worldwide, three pressing hydrologic needs stand out: first, to better understand the processes controlling the partitioning of energy and water fluxes within and out from these systems; second, to better understand feedbacks between hydrological fluxes and biogeochemical and ecological processes; and, third, to enhance our physical and empirical understanding with integrated measurement strategies and information systems. We envision an integrative approach to monitoring, modeling, and sensing the mountain environment that will improve understanding and prediction of hydrologic fluxes and processes. Here extensive monitoring of energy fluxes and hydrologic states are needed to supplement existing measurements, which are largely limited to streamflow and snow water equivalent. Ground‐based observing systems must be explicitly designed for integration with remotely sensed data and for scaling up to basins and whole ranges.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2005WR004387","usgsCitation":"Bales, R.C., Molotch, N.P., Painter, T.H., Dettinger, M., Rice, R., and Dozier, J., 2006, Mountain hydrology of the western United States: Water Resources Research, v. 42, no. 8, Article W08432; 13 p., https://doi.org/10.1029/2005WR004387.","productDescription":"Article W08432; 13 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":477359,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2005wr004387","text":"Publisher Index Page"},{"id":237264,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"42","issue":"8","noUsgsAuthors":false,"publicationDate":"2006-08-26","publicationStatus":"PW","scienceBaseUri":"505a5eb5e4b0c8380cd70c02","contributors":{"authors":[{"text":"Bales, Roger C.","contributorId":189659,"corporation":false,"usgs":false,"family":"Bales","given":"Roger","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":416887,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Molotch, Noah P. 0000-0003-4733-8060","orcid":"https://orcid.org/0000-0003-4733-8060","contributorId":203466,"corporation":false,"usgs":false,"family":"Molotch","given":"Noah","email":"","middleInitial":"P.","affiliations":[{"id":36627,"text":"University of Colorado, Boulder","active":true,"usgs":false}],"preferred":false,"id":416888,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Painter, Thomas H.","contributorId":193067,"corporation":false,"usgs":false,"family":"Painter","given":"Thomas","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":416892,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dettinger, Michael D. 0000-0002-7509-7332 mddettin@usgs.gov","orcid":"https://orcid.org/0000-0002-7509-7332","contributorId":146383,"corporation":false,"usgs":true,"family":"Dettinger","given":"Michael D.","email":"mddettin@usgs.gov","affiliations":[],"preferred":false,"id":416891,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Rice, Robert","contributorId":149915,"corporation":false,"usgs":false,"family":"Rice","given":"Robert","affiliations":[],"preferred":false,"id":416890,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Dozier, Jeff","contributorId":190695,"corporation":false,"usgs":false,"family":"Dozier","given":"Jeff","email":"","affiliations":[],"preferred":false,"id":416889,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Volcano eruption and earthquake frequencies are low, with indications of spatial and temporal clustering, making probabilistic assessments difficult. In an effort to identify the most likely intrusion sites, we based a three-dimensional finite-element model on the expectation that faulting and basalt intrusions are sensitive to the magnitude and orientation of the least principal stress in extensional terranes. We found that in the absence of fault slip, variation in overburden pressure caused a stress state that preferentially favored intrusions at Crater Flat. However, when we allowed central Yucca Mountain faults to slip in the model, we found that magmatic clustering was not favored at Crater Flat or in the central Yucca Mountain block. Instead, we calculated that the stress field was most encouraging to intrusions near fault terminations, consistent with the location of the most recent volcanism at Yucca Mountain, the Lathrop Wells cone. We found this linked fault and magmatic system to be mutually reinforcing in the model in that Lathrop Wells feeder dike inflation favored renewed fault slip. ?? 2006 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G22636.1","issn":"00917613","usgsCitation":"Parsons, T., Thompson, G.A., and Cogbill, A., 2006, Earthquake and volcano clustering via stress transfer at Yucca Mountain, Nevada: Geology, v. 34, no. 9, p. 785-788, https://doi.org/10.1130/G22636.1.","startPage":"785","endPage":"788","numberOfPages":"4","costCenters":[],"links":[{"id":236923,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210104,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G22636.1"}],"volume":"34","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a04bbe4b0c8380cd50ae6","contributors":{"authors":[{"text":"Parsons, T.","contributorId":48288,"corporation":false,"usgs":true,"family":"Parsons","given":"T.","email":"","affiliations":[],"preferred":false,"id":417521,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thompson, G.
