The result showed that the genesis of abundant pyrites in bed 24e2 at the uppermost part of the Changxing Formation in the Meishan section may be related to volcanic activity. In bed 24e2 of the Meishan section, pyrite has its highest content of 1.84% and the sulfur isotope composition has the highest ??34S value at + 2.2??? which is very similar to that of the average value of volcanic gas. There are some volcanic products such as ??-quartz, siliceous cylinders and siliceous spherules which coexisted with pyrites in beds 24e2 and 24f. It can be concluded that a large quantity of volcanic ash fell into the South China Sea and was incorporated into marine sediments during the formation of limestone at the uppermost part of the Changxing Formation. The volcanic eruption with massive amounts of H2S and S02 gas at the end of the Permian period resulted in the enrichment of H2S in the South China Sea areas.

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.

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.

A central safety feature is the prevention, or sufficient retardation, of radionuclide (RN) migration to the biosphere. To this end, radionuclide sorption is one of the most important processes. Decreasing the uncertainty in radionuclide sorption may contribute significantly to reducing the overall uncertainty of a performance assessment (PA). For PA, sorption is typically characterised by distribution coefficients (Kd values). The conditional nature of Kd requires different estimates of this parameter for each set of geochemical conditions of potential relevance in a RN's migration pathway. As it is not feasible to measure sorption for every set of conditions, the derivation of Kd for PA must rely on data derived from representative model systems. As a result, uncertainty in Kd is largely caused by the need to derive values for conditions not explicitly addressed in experiments. The recently concluded NEA Sorption Project [1] showed that thermodynamic sorption models (TSMs) are uniquely suited to derive K d as a function of conditions, because they allow a direct coupling of sorption with variable solution chemistry and mineralogy in a thermodynamic framework. The results of the project enable assessment of the suitability of various TSM approaches for PA-relevant applications as well as of the potential and limitations of TSMs to model RN sorption in complex systems. ?? by Oldenbourg Wissenschaftsverlag.","largerWorkTitle":"Radiochimica Acta","language":"English","doi":"10.1524/ract.2006.94.9-11.779","issn":"00338230","usgsCitation":"Ochs, M., Davis, J., Olin, M., Payne, T., Tweed, C., Askarieh, M., and Altmann, S., 2006, Use of thermodynamic sorption models to derive radionuclide Kd values for performance assessment: Selected results and recommendations of the NEA sorption project, <i>in</i> Radiochimica Acta, v. 94, no. 9-11, p. 779-785, https://doi.org/10.1524/ract.2006.94.9-11.779.","startPage":"779","endPage":"785","numberOfPages":"7","costCenters":[],"links":[{"id":209881,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1524/ract.2006.94.9-11.779"},{"id":236624,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"9-11","noUsgsAuthors":false,"publicationDate":"2009-09-25","publicationStatus":"PW","scienceBaseUri":"505bbfa2e4b08c986b329c9a","contributors":{"authors":[{"text":"Ochs, M.","contributorId":92025,"corporation":false,"usgs":true,"family":"Ochs","given":"M.","email":"","affiliations":[],"preferred":false,"id":420617,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Davis, J.A.","contributorId":71694,"corporation":false,"usgs":true,"family":"Davis","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":420614,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olin, M.","contributorId":58439,"corporation":false,"usgs":true,"family":"Olin","given":"M.","email":"","affiliations":[],"preferred":false,"id":420613,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Payne, T.E.","contributorId":31916,"corporation":false,"usgs":true,"family":"Payne","given":"T.E.","email":"","affiliations":[],"preferred":false,"id":420612,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Tweed, C.J.","contributorId":90087,"corporation":false,"usgs":true,"family":"Tweed","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":420616,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Askarieh, M.M.","contributorId":94841,"corporation":false,"usgs":true,"family":"Askarieh","given":"M.M.","email":"","affiliations":[],"preferred":false,"id":420618,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Altmann, S.","contributorId":75321,"corporation":false,"usgs":true,"family":"Altmann","given":"S.","email":"","affiliations":[],"preferred":false,"id":420615,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

This paper attempts to define and evaluate the cartographic value of contemporary map-like art by placing the body of work as a whole in the theoretical concepts proposed by J.M. Blaut and his colleagues about mapping as a cognitive and cultural universal. This paper discusses how map art resembles mapping characteristics similar to those observed empirically in very young children as described in the publications of Blaut and others. The theory proposes that these early mapping skills are later structured and refined by their social context and practice. Diverse cultural contexts account for the varieties, types, and degrees of mapping behavior documented with time and geographic place. The dynamics of early mapping are compared to mapping techniques employed by artists. The discipline of fine art serves as the context surrounding map artists and their work.

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.

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. However, these concentrations are not likely to be of concern because they are not known to cause chronic toxicity. Depuration experiments indicated that June suckers stocked into Utah Lake would eliminate accumulated selenium residues within 3 months. Results indicated that Goshen Warm Springs could be used for fish propagation. In addition, further evaluation of Utah Lake as an interim hatchery site for June suckers should be considered.</p>","language":"English","publisher":"Taylor & Francis","doi":"10.1577/M05-063.1","issn":"02755947","usgsCitation":"Allert, A., Fairchild, J.F., May, T.W., Sappington, L.C., Darnall, N., and Wilson, M., 2006, Using on-site bioassays to determine selenium risk to propagated endangered fishes: North American Journal of Fisheries Management, v. 26, no. 2, p. 308-316, https://doi.org/10.1577/M05-063.1.","productDescription":"9 p.","startPage":"308","endPage":"316","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":236476,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"2","noUsgsAuthors":false,"publicationDate":"2006-05-01","publicationStatus":"PW","scienceBaseUri":"505bc08ae4b08c986b32a1a3","contributors":{"authors":[{"text":"Allert, Ann L. aallert@usgs.gov","contributorId":494,"corporation":false,"usgs":true,"family":"Allert","given":"Ann L.","email":"aallert@usgs.gov","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":419579,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fairchild, James F. jfairchild@usgs.gov","contributorId":492,"corporation":false,"usgs":true,"family":"Fairchild","given":"James","email":"jfairchild@usgs.gov","middleInitial":"F.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":419583,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"May, Thomas W. tmay@usgs.gov","contributorId":2598,"corporation":false,"usgs":true,"family":"May","given":"Thomas","email":"tmay@usgs.gov","middleInitial":"W.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":419580,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sappington, Linda C.","contributorId":20821,"corporation":false,"usgs":true,"family":"Sappington","given":"Linda","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":419581,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Darnall, N.","contributorId":86551,"corporation":false,"usgs":true,"family":"Darnall","given":"N.","affiliations":[],"preferred":false,"id":419582,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Wilson, M.","contributorId":97842,"corporation":false,"usgs":true,"family":"Wilson","given":"M.","affiliations":[],"preferred":false,"id":419584,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

By their very nature, hyperspectral data place unique and demanding requirements on the computer software used to visualize, analyze, process and interpret them. Often described as a marriage of the two technologies of reflectance spectroscopy and airborne/spaceborne remote sensing, imaging spectroscopy, in fact, produces data sets with unique qualities, unlike previous remote sensing or spectrometer data. Because of these unique spatial and spectral properties hyperspectral data are not readily processed or exploited with legacy software systems inherited from either of the two parent fields of study.

The fast loess accumulation during the late Wisconsin glaciation interacted with the incipient pedogenesis and caused unclear boundaries of loess-paleosol alternations in soil horizonation and mineralogy. Parameters of grain size distribution, sedimentation rate, matrix carbonate content and diffuse reflectance (i.e. soil colors and iron oxides) are used in this paper to discuss the geological and pedological influences for the Peoria Loess in Keller Farm section in southern Illinois. The multi-proxy analysis revealed that many paleosol A horizons, defined by the diffuse reflectance variability, contain finer-grained materials with a relatively higher sedimentation rate. It suggests that glaciofluvial sediments were available in the source areas for uploading eolian dust during the temporary ice sheet retreats. The denser vegetation and wetter surface soils on the loess deposit area could increase the dust trapping efficiency and caused a greater accumulation rate of loess deposits. The coarser-grained materials and slower sedimentation rate are often found in loess layers. It suggests that strong surface winds transported the coarser-grained materials from local dust sources and sparse vegetation and dry surface soils reduced the dust trapping efficiency during the ice sheet readvance. The strong interactions between the geological and pedological processes played an important role on the loess-paleosol alternations in southern Illinois during the late Wisconsin glaciation. ?? 2006 Elsevier B.V.

Within occupied wetlands, shoreline microhabitat where nests occurred was best distinguished from available, unoccupied shoreline microhabitat by steeper shore, greater near-shore and basin water depth, deeper nesting vegetation, presence of moss spp. and winterberry (Ilex verticillata), and a negative association with S. alba, leatherleaf (Chamaedaphne calyculata), and K. angustifolia.

In most cases it is assumed that seismic instruments are only sensitive to the translational motion of the instrument's base. In this study the full equation of pendulum motion, including the inputs of rotations and tilts, is considered. It is shown that tilting the accelerograph's base can severely impact its response to the ground motion. The method of tilt evaluation using uncorrected strong-motion accelerograms was first suggested by Graizer (1989), and later tested in several laboratory experiments with different strong-motion instruments. The method is based on the difference in the tilt sensitivity of the horizontal and vertical pendulums. The method was applied to many of the strongest records of the Mw 6.7 Northridge earthquake of 1994. Examples are shown when relatively large tilts of up to a few degrees occurred during strong earthquake ground motion. Residual tilt extracted from the strong-motion record at the Pacoima Dam-Upper Left Abutment reached 3.1?? in N45??E direction, and was a result of local earthquake-induced tilting due to high-amplitude shaking. This value is in agreement with the residual tilt measured by using electronic level a few days after the earthquake. The method was applied to the building records from the Northridge earthquake. According to the estimates, residual tilt reached 2.6?? on the ground floor of the 12-story Hotel in Ventura. Processing of most of the strongest records of the Northridge earthquake shows that tilts, if happened, were within the error of the method, or less than about 0.5??.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120060065","issn":"00371106","usgsCitation":"Graizer, V., 2006, Tilts in strong ground motion: Bulletin of the Seismological Society of America, v. 96, no. 6, p. 2090-2102, https://doi.org/10.1785/0120060065.","startPage":"2090","endPage":"2102","numberOfPages":"13","costCenters":[],"links":[{"id":209936,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120060065"},{"id":236696,"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":"505bb38fe4b08c986b325e74","contributors":{"authors":[{"text":"Graizer, V.","contributorId":88930,"corporation":false,"usgs":true,"family":"Graizer","given":"V.","email":"","affiliations":[],"preferred":false,"id":420629,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

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.

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. ??

Record high temperatures occurred throughout the western United States during the second week of March, and U.S. Geological Survey (USGS) stream gauges throughout the area recorded early onsets of streamflow at this time. However, a set of nested subbasins in Yosemite National Park, California, told a more complicated story. In spite of high air temperatures, many streams draining high-elevation basins did not start flowing until later in the spring. Temperatures during early March 2004 were as high as temperatures in late March 2002, when streams at all of the monitored Yosemite basins began flowing at the same time. However, the March 2004 onset occurred before the spring equinox, when the sun was lower in the sky. Thus, shading and solar radiation differences played a much more important role in 2004, leading to differences in streamflow timing. These results suggest that as temperatures warm and spring melt shifts earlier in the season, topographic effects will play an even more important role than at present in determining snowmelt timing. ?? 2006 American Meteorological Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrometeorology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1175/JHM539.1","issn":"1525755X","usgsCitation":"Lundquist, J., and Flint, A.L., 2006, Onset of snowmelt and streamflow in 2004 in the Western Unites States: How shading may affect spring streamflow timing in a warmer world: Journal of Hydrometeorology, v. 7, no. 6, p. 1199-1217, https://doi.org/10.1175/JHM539.1.","startPage":"1199","endPage":"1217","numberOfPages":"19","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":477543,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1175/jhm539.1","text":"Publisher Index Page"},{"id":236722,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209956,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1175/JHM539.1"}],"volume":"7","issue":"6","noUsgsAuthors":false,"publicationDate":"2006-12-01","publicationStatus":"PW","scienceBaseUri":"505a6e42e4b0c8380cd75571","contributors":{"authors":[{"text":"Lundquist, J.D.","contributorId":93243,"corporation":false,"usgs":true,"family":"Lundquist","given":"J.D.","affiliations":[],"preferred":false,"id":419793,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flint, A.

We began radio collaring ferrets in 1981. Use of radio telemetry on ferrets proved to be both challenging and rewarding. We document two decades of development and use that led to the present radio-tagging techniques and methods for radio tracking. The 7-g radio collar commonly used after 1992 was smaller and lighter, relative to mass and size of subjects, than collars used in studies of other Mustela. Other important developments were a Teflon® coating to shed mud, a highly flexible stainless steel cable for whip antennas, and a nondurable wool collar. Although collar-caused neck abrasions have continued to occur sporadically, a retrospective assessment of minimum survival rates for 724 reintroduced ferrets (392 radio tagged), using data from spotlight surveys, failed to detect negative effects of radio-collars. In a South Dakota study, ferrets that were found to have hair loss or neck abrasions when collars were removed did not exhibit movements significantly different from those of radio-tagged ferrets with no evidence of neck problems. Prototype transmitters designed for surgical implantation had insufficient power output for effective use on ferrets. Early attempts at tracking radio-tagged ferrets by following the signal on foot quickly gave way to following movements by triangulation, which does not disturb the subjects. The most effective tracking stations were camper trailers fitted with rotatable, 11-element, dual-beam Yagi antennas on 6-m masts. We used radio telemetry to produce 83,275 lines of data (44,191 indications of status and 39,084 positional fixes via triangulation) for 340 radio-collared ferrets during the reintroduction program. Tracking by hand and from aircraft augmented triangulation, allowing us to locate animals that dispersed long distances and enabling us to determine causes of mortality.

Consequently, monitoring populations of both native and nonnative fishes is important for conservation of native species. We used data collected from Muddy Creek, Wyoming (2003-2004), to compare sample size estimates using a random and a fixed-site sampling design to monitor changes in catch per unit effort (CPUE) of native bluehead suckers Catostomus discobolus, flannelmouth suckers C. latipinnis, roundtail chub Gila robusta, and speckled dace Rhinichthys osculus, as well as nonnative creek chub Semotilus atromaculatus and white suckers C. commersonii. When one-pass backpack electrofishing was used, detection of 10% or 25% changes in CPUE (fish/100 m) at 60% statistical power required 50-1,000 randomly sampled reaches among species regardless of sampling design. However, use of a fixed-site sampling design with 25-50 reaches greatly enhanced the ability to detect changes in CPUE. The addition of seining did not appreciably reduce required effort. When detection of 25-50% changes in CPUE of native and nonnative fishes is acceptable, we recommend establishment of 25-50 fixed reaches sampled by one-pass electrofishing in Muddy Creek. Because Muddy Creek has habitat and fish assemblages characteristic of other headwater streams in the UCRB, our results are likely to apply to many other streams in the basin. ??

Here, we experimentally manipulated nest predation risk across a landscape and asked the question, do migratory birds assess and respond to variation in nest predation risk when choosing breeding habitats? We examined habitat preference by quantifying the density and settlement date of eight species of migratory passerines breeding in areas with and without intact nest predator communities. We found consistently more individuals nesting in areas with reduced nest predation than in areas with intact predator assemblages, although predation risk had no influence on settlement or breeding phenology. Additionally, those individuals occupying safer nesting habitats exhibited increased singing activity. These findings support a causal relationship between habitat choice and nest predation risk and suggest the importance of nest predation risk in shaping avian community structure and breeding activity. ?? 2006 by The University of Chicago.

Mercury in bituminous coal is found primarily within Fe-sulfides, whereas lower rank coal tends to have a greater proportion of organic-bound Hg. Preparation of bituminous coal to reduce S generally reduces input Hg relative to in-ground concentrations, but the amount of this reduction varies according to the fraction of Hg in sulfides and the efficiency of sulfide removal. The mode of occurrence of Hg in coal does not directly affect the speciation of Hg in the combustion flue gas. However, other constituents in the coal, notably Cl and S, and the combustion characteristics of the coal, influence the species of Hg that are formed in the flue gas and enter air pollution control devices. The formation of gaseous oxidized Hg or particulate-bound Hg occurs post-combustion; these forms of Hg can be in part captured in the air pollution control devices that exist on coal-fired boilers, without modification. For a given coal type, the capture efficiency of Hg by pollution control systems varies according to type of device and the conditions of its deployment. For bituminous coal, on average, more than 60% of Hg in flue gas is captured by fabric filter (FF) and flue-gas desulfurization (FGD) systems. Key variables affecting performance for Hg control include Cl and S content of the coal, the positioning (hot side vs. cold side) of the system, and the amount of unburned C in coal ash. Knowledge of coal quality parameters and their effect on the performance of air pollution control devices allows optimization of Hg capture co-benefit.&nbsp;</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.apgeochem.2006.08.001","issn":"08832927","usgsCitation":"Kolker, A., Senior, C.L., and Quick, J., 2006, Mercury in coal and the impact of coal quality on mercury emissions from combustion systems: Applied Geochemistry, v. 21, no. 11, p. 1821-1836, https://doi.org/10.1016/j.apgeochem.2006.08.001.","productDescription":"16 p.","startPage":"1821","endPage":"1836","costCenters":[],"links":[{"id":236720,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a540ee4b0c8380cd6ce80","contributors":{"authors":[{"text":"Kolker, Allan 0000-0002-5768-4533 akolker@usgs.gov","orcid":"https://orcid.org/0000-0002-5768-4533","contributorId":643,"corporation":false,"usgs":true,"family":"Kolker","given":"Allan","email":"akolker@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":419641,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Senior, Constance L.","contributorId":131002,"corporation":false,"usgs":false,"family":"Senior","given":"Constance","email":"","middleInitial":"L.","affiliations":[{"id":7205,"text":"ADA-ES, Inc.

Compared to its relatives, the black-footed ferret is an extreme specialist, depending on the prairie dogs (Cynomys spp.) of North American grasslands for food and using prairie dog burrows for shelter. The black-footed ferret’s close association with prairie dogs was an important factor in its decline. Prairie dogs were regarded as an agricultural pest as human settlement progressed westward, and they became important hosts for plague as that disease colonized eastward from its sources of introduction on the west coast. Prairie dog numbers were dramatically reduced by poisoning, cropland conversions, and plague during the first half of the 20th century, and black-footed ferret populations declined precipitously. The black-footed ferret was included on the first lists of endangered species, and its status was precarious by the time the Endangered Species Act of 1973 was passed. Its rebound from a low point of 10 known individuals in spring of 1985 (Biggins and others, 2006) is impressive, but the species is not yet “recovered” in either the biological or legal sense (for further details, see Lockhart and others, this volume).</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Recovery of the black-footed ferret: Progress and continuing challenges- Proceedings of the Symposium on the Status of the Black-footed Ferret and Its Habitat, Fort Collins, Colorado, January 28-29, 2004 (Scientific Investigations Report 2005-5293)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"conferenceTitle":"Symposium on the Status of the Black-footed Ferret and Its Habitat","conferenceDate":"January 28-29, 2004","conferenceLocation":"Fort Collins, CO","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Biggins, D.E., 2006, The symposium in context, <i>in</i> Recovery of the black-footed ferret: Progress and continuing challenges- Proceedings of the Symposium on the Status of the Black-footed Ferret and Its Habitat, Fort Collins, Colorado, January 28-29, 2004 (Scientific Investigations Report 2005-5293), Fort Collins, CO, January 28-29, 2004, p. 3-5.","productDescription":"3 p.","startPage":"3","endPage":"5","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":334911,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":334910,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2005/5293/report.pdf#page=14","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"589aeab3e4b0efcedb72d24f","contributors":{"authors":[{"text":"Biggins, Dean E. 0000-0003-2078-671X bigginsd@usgs.gov","orcid":"https://orcid.org/0000-0003-2078-671X","contributorId":2522,"corporation":false,"usgs":true,"family":"Biggins","given":"Dean","email":"bigginsd@usgs.gov","middleInitial":"E.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":662810,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
