The effects of impervious area, septic leach-field effluent, and a riparian wetland on runoff generation were studied in three small (0.38–0.56 km2) headwater catchments that represent a range of suburban development (high density residential, medium density residential, and undeveloped) within the Croton River basin, 70 km north of New York City. Precipitation, stream discharge, and groundwater levels were monitored at 10–30 min intervals for 1 year, and stream water and groundwater samples were collected biweekly for δ18O, NO3−, and SO42− analysis for more than 2 years during an overlapping period in 2000–2002. Data from 27 storms confirmed that peak magnitudes increased and recession time decreased with increasing development, but lags in peak arrival and peak discharge/mean discharge were greatest in the medium density residential catchment, which contains a wetland in which storm runoff is retained before entering the stream. Baseflow during a dry period from Aug. 2001–Feb. 2002 was greatest in the high-density residential catchment, presumably from the discharge of septic effluent through the shallow groundwater system and into the stream. In contrast, moderate flows during a wet period from Mar.–Aug. 2002 were greatest in the undeveloped catchment, possibly as a result of greater subsurface storage or greater hydraulic conductivity at this site. The mean residence time of baseflow was about 30 weeks at all three catchments, indicating that human influence was insufficient to greatly affect the groundwater recharge and discharge properties that determine catchment residence time. These results suggest that while suburban development and its associated impervious surfaces and storm drains accelerate the transport of storm runoff into streams, the combined effects of remnant natural landscape features such as wetlands and human alterations such as deep groundwater supply and septic systems can change the expected effects of human development on storm runoff and groundwater recharge.
Knowledge of Yellowstone bison (Bison bison) parturition patterns allows managers to refine risk assessments and manage to reduce the potential for transmission of brucellosis between bison and cattle. We used historical (1941) and contemporary (1989–2002) weights and morphometric measurements of Yellowstone bison fetuses to describe fetal growth and to predict timing and synchrony of parturition. Our method was supported by agreement between our predicted parturition pattern and observed birth dates for bison that were taken in to captivity while pregnant. The distribution of parturition dates in Yellowstone bison is generally right-skewed with a majority of births in April and May and few births in the following months. Predicted timing of parturition was consistently earlier for bison of Yellowstone's northern herd than central herd. The predicted median parturition date for northern herd bison in the historical period was 3 to 12 days earlier than for 2 years in the contemporary period, respectively. Median predicted birth dates and birthing synchrony differed within herds and years in the contemporary period. For a single year of paired data, the predicted median birth date for northern herd bison was 14 days earlier than for central herd bison. This difference is coincident with an earlier onset of spring plant growth on the northern range. Our findings permit refinement of the timing of separation between Yellowstone bison and cattle intended to reduce the probability of transmission of brucellosis from bison to cattle.

We studied effects of cultivated land on Greater Sage-Grouse lek abandonment in North and South Dakota. Landscape-level data were assessed using satellite imagery within a geographic information system. Comparisons were made of 1972-1976 and 1999-2000 percent cultivated and noncultivated land. These comparisons were made between land uses surrounding active leks versus inactive leks, active leks versus random locations, and abandoned regions versus active regions. The 1999-2000 imagery illustrated that percent cultivated land was greater near abandoned leks (4-km buffers) than near active leks in North Dakota or random sites, but this did not hold true in South Dakota. Comparison of an extensive region of abandoned leks with a region of active leks in North Dakota illustrated a similar increase as well as dispersion of cultivation within the abandoned region. However, 1972-1976 imagery revealed that this relationship between percentage of cultivated land and lek activity in North Dakota has been static over the last 30 years. Thus, if the decline of Greater Sage-Grouse is the result of cultivated land infringements, it occurred prior to 1972 in North Dakota.

The loading model includes slip below 12 km along the transform as well as motion of the Pacific plate, and it is consistent with most available Global Positioning System (GPS) displacement rate data. Coulomb stress transfer is shown to have been a weak contributing factor in the failure of the southeastern (Sitka) segment of the Fairweather fault in 1972, hastening the occurrence of the earthquake by only about 8 months. Failure of the Sitka segment was enhanced by a combination of cumulative loading from below (95%) by slip of about 5 cm/yr since 1848, by stress transfer (about 1%) from major earthquakes on straddling segments of the Queen Charlotte fault (M 8.1 in 1949) and the Fairweather fault (M 7.8 in 1958), and by viscoelastic relaxation (about 4%) following the great 1964 Alaska earthquake, modeled by Pollitz et al. (1998). Cumulative stress increases in excess of 7 MPa at a depth of 8 km are projected prior to the M 7.6 earthquake. Coulomb stress transferred by the rupture of the great M 9.2 Alaska earthquake in 1964 (Bufe, 2004a) also hastened the occurrence of the 1972 event, but only by a month or two. Continued tectonic loading over the last half century and stress transfer from the M 7.6 Sitka event has resulted in restressing of the adjacent segments by about 3 MPa at 8 km depth. The occurrence of a M 6.8 earthquake on the northwestern part of the Queen Charlotte fault on 28 June 2004, the largest since 1949, also suggests increased stress. The Cape St. James segment of the fault immediately southeast of the 1949 Queen Charlotte rupture has accumulated about 6 MPa at 8 km through loading since 1900 and stress transfer in 1949. A continued rise in earthquake hazard is indicated for the Alaska panhandle and Queen Charlotte Islands region in the decades ahead as the potential for damaging earthquakes increases.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120040171","issn":"00371106","usgsCitation":"Bufe, C., 2005, Stress distribution along the Fairweather-Queen Charlotte transform fault system: Bulletin of the Seismological Society of America, v. 95, no. 5, p. 2001-2008, https://doi.org/10.1785/0120040171.","startPage":"2001","endPage":"2008","numberOfPages":"8","costCenters":[],"links":[{"id":210986,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120040171"},{"id":238109,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"95","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9b55e4b08c986b31cdef","contributors":{"authors":[{"text":"Bufe, C.

There are many important societal issues in which scientific information can play a critical role. Science can add greatly to policy and management decisions to minimize loss of life and property from natural and man-made disasters, to manage water, biological, energy, and mineral resources, and in general, to enhance and protect our quality of life. However, the link between science and decision-making is often complicated and imperfect. Technical language and methods surround scientific research and the dissemination of its results. Scientific investigations often are conducted under different conditions, with different spatial boundaries, and in different timeframes than those needed to support specific policy and societal decisions. Uncertainty is not uniformly reported in scientific investigations. If society does not know that data exist, what the data mean, where to use the data, or how to include uncertainty when a decision has to be made, then science gets left out -or misused- in a decision making process. This paper is about using Geospatial Decision Support Systems (GDSS) for quantitative policy analysis. Integrated natural -social science methods and tools in a Geographic Information System that respond to decision-making needs can be used to close the gap between science and society. The GDSS has been developed so that nonscientists can pose \"what if\" scenarios to evaluate hypothetical outcomes of policy and management choices. In this approach decision makers can evaluate the financial and geographic distribution of potential policy options and their societal implications. Actions, based on scientific information, can be taken to mitigate hazards, protect our air and water quality, preserve the planet's biodiversity, promote balanced land use planning, and judiciously exploit natural resources. Applications using the GDSS have demonstrated the benefits of utilizing science for policy decisions. Investment in science reduces decision-making uncertainty and reducing that uncertainty has economic value.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Boletin Geologico y Minero","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03660176","usgsCitation":"Bernknopf, R., 2005, Geospatial decision support systems for societal decision making: Boletin Geologico y Minero, v. 116, no. 4, p. 325-330.","startPage":"325","endPage":"330","numberOfPages":"6","costCenters":[],"links":[{"id":238076,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"116","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a28ace4b0c8380cd5a2e6","contributors":{"authors":[{"text":"Bernknopf, R.

We assessed habitat preference using radio relocation points and 50-m radius buffers of radio relocation points. Our data suggested that foraging male goshawks used early-successional upland conifer stands (???25 yrs old), early-successional upland deciduous stands (???50 yrs old), late-successional upland conifer stands (???50 yrs old), and late-successional upland deciduous stands (???50 yrs old) more frequently than expected based on the abundance of these vegetation types in the landscape. The 2 most available stand types, early-successional upland deciduous (<25 yrs old) and all ages of late-successional lowland conifer stands, were used less than expected by foraging goshawks. Late-successional lowland deciduous stands (???50 yrs old) were used in proportion to availability. Although analysis of relocation points suggested early-successional upland deciduous stands (25-49 yrs old) and late-successional upland conifer stands (???50 yrs old) were used in proportion to availability, analysis of buffers around relocation points indicated that these stand types were also used more than expected by foraging goshawks. Regardless of vegetation community type, stands used by goshawks were structurally similar with high canopy and understory stem densities, high canopy closure, substantial shrub cover, and large amounts of woody debris. Nest stands consisted of taller and larger diameter canopy trees and fewer understory trees than foraging stands, but stands were otherwise similar in structural features, suggesting goshawks used similar stands for nesting and foraging but that they tended to select the most mature stands for nesting. A commonality among nesting and foraging stands was the presence of open spaces between the canopy and understory foliage, and between understory and shrub layer foliage. In our study area, these spaces may have served as relatively unobstructed flight paths where foraging and nesting stands possessed stem densities at the upper end of that reported for goshawk habitat.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/0022-541X(2005)69[1516:FANHOB]2.0.CO;2","issn":"0022541X","usgsCitation":"Boal, C.W., Andersen, D., and Kennedy, P., 2005, Foraging and nesting habitat of breeding male northern goshawks in the laurentian mixed forest province, Minnesota: Journal of Wildlife Management, v. 69, no. 4, p. 1516-1527, https://doi.org/10.2193/0022-541X(2005)69[1516:FANHOB]2.0.CO;2.","startPage":"1516","endPage":"1527","numberOfPages":"12","costCenters":[],"links":[{"id":210944,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/0022-541X(2005)69[1516:FANHOB]2.0.CO;2"},{"id":238038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a12f3e4b0c8380cd5446e","contributors":{"authors":[{"text":"Boal, C.

Prairie wetland communities are strongly influenced by regional physiography and climate, resulting in extreme spatial and temporal variability relative to other aquatic ecosystems. Given the strong influence of abiotic factors, PPR wetland communities have been viewed traditionally in the context of their responses to chemical and physical features of landscape and climate. Although useful, this physical-chemical paradigm may fail to account for ecosystem variability due to biotic influences, particularly those associated with presence of fish. Spatial and temporal variability in fish populations, in turn, may reflect anthropogenic activities, landscape characteristics, and climate-mediated effects on water levels, surface connectivity, and hydroperiods. We reviewed studies assessing influences of fish on prairie wetlands and examined precipitation patterns and biological data from PPR wetlands in east-central North Dakota and western Minnesota, USA. Our review and analysis indicated that native fish influence many characteristics of permanently flooded prairie wetlands, including water clarity and abundance of phytoplankton, submerged macrophytes, and aquatic invertebrates. We suggest that ecologists and managers will benefit from conceptual paradigms that better meld biotic interactions associated with fish, and perhaps other organisms, with chemical and physical influences on prairie wetland communities. ?? 2005, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/0277-5212(2005)025[0764:BIADOE]2.0.CO;2","issn":"02775212","usgsCitation":"Hanson, M., Zimmer, K., Butler, M.G., Tangen, B., Herwig, B., and Euliss, N., 2005, Biotic interactions as determinants of ecosystem structure in prairie wetlands: An example using fish: Wetlands, v. 25, no. 3, p. 764-775, https://doi.org/10.1672/0277-5212(2005)025[0764:BIADOE]2.0.CO;2.","startPage":"764","endPage":"775","numberOfPages":"12","costCenters":[],"links":[{"id":210943,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/0277-5212(2005)025[0764:BIADOE]2.0.CO;2"},{"id":238037,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f1a3e4b0c8380cd4ad61","contributors":{"authors":[{"text":"Hanson, M.A.","contributorId":61393,"corporation":false,"usgs":true,"family":"Hanson","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":415423,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zimmer, K.D.","contributorId":79435,"corporation":false,"usgs":true,"family":"Zimmer","given":"K.D.","email":"","affiliations":[],"preferred":false,"id":415424,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Butler, Malcolm G.","contributorId":56188,"corporation":false,"usgs":false,"family":"Butler","given":"Malcolm","email":"","middleInitial":"G.","affiliations":[{"id":12813,"text":"Department of Biological Sciences, North Dakota State University","active":true,"usgs":false}],"preferred":false,"id":415422,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tangen, B.A.","contributorId":102687,"corporation":false,"usgs":true,"family":"Tangen","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":415425,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Herwig, B.R.","contributorId":13032,"corporation":false,"usgs":true,"family":"Herwig","given":"B.R.","email":"","affiliations":[],"preferred":false,"id":415420,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Euliss, N.H.

Bromide was applied to the surface of a sandy soil during the dry season. During the subsequent rainy season, repeated sediment sampling tracked the movement of bromide through the profile. Analysis of data on moisture content, matric pressure, unsaturated hydraulic conductivity, bulk density, and soil texture and structure provides insights into parameterization and use of the advective‐dispersive modeling approach. Capturing the gross features of tracer and moisture movement with model simulations required an order‐of‐magnitude increase in laboratory‐measured hydraulic conductivity. Wetting curve characteristics better represented field results, calling into question the routine estimation of hydraulic characteristics based only on drying conditions. Measured increases in profile moisture exceeded cumulative precipitation in early winter, indicating that gains from dew drip can exceed losses from evapotranspiration during periods of heavy (“Tule”) fog. A single‐continuum advective‐dispersive modeling approach could not reproduce a peak of bromide that was retained near the soil surface for over 3 years. Modeling of this feature required slow exchange of solute at a transfer rate of 0.5–1 × 10−4 d−1 with an immobile volume approaching the residual moisture content.

The OFZ, which is a 150 km wide rift zone showing 600 km of right-lateral movement in a NW-SE direction, is unique among the fracture zones of the Pacific in that it includes many old seamounts (e.g., Magellan Seamounts and seamounts on Dutton Ridge). Sub-seafloor acoustic echoes on the seamounts are classified into nine specific types based on the nature and continuity of the echoes, subbottom structure, and morphology of the seafloor: (1) distinct echoes (types I-1, I-2, I-3), (2) indistinct echoes (types II-1, II-2, II-3), and (3) hyperbolic echoes (types III-1, III-2, III-3). Type I-2 pelagic sediments, characterized by thin and intermittent coverage, were probably deposited in topographically sheltered areas when bottom currents were strong, whereas type I-1 pelagic sediments accumulated during continuous and widespread sedimentation. Development of seamount flank rift zones in the OFZ may have been influenced by preexisting structures in the transform fracture zone at the time of volcanism, whereas those on Ita Mai Tai seamount in the Pigafetta Basin originated solely by edifice-building processes. Flank rift zones that formed by dike intrusions and eruptions played an important role in mass wasting. Mass-wasting processes included block faulting or block slides around the summit margin, sliding/slumping, debris flows, and turbidites, which may have been triggered by faulting, volcanism, dike injection, and weathering during various stages in the evolution of the seamounts. ?? 2005 Elsevier Ltd.

We used a digital X-ray system to extract images of the forefoot skeleton from 101 dried skins of eight taxa (seven species, including two subspecies of one species) of these shrews. Lengths and widths of each of the four bones of digit III were measured directly from the digital images, and we used these data to quantify variation within and among taxa. Analysis of the images and measurements showed that interspecific variation exceeds intraspecific variation. In fact, most taxa could be distinguished in multivariate and some bivariate plots. Our quantitative data helped us define a number of specific forefoot characters that we subsequently used to hypothesize evolutionary relationships among the taxa using the exhaustive search option in PAUP, a computer program for phylogenetic analysis. The resulting trees generally concur with previously published evolutionary hypotheses for small-eared shrews. Cryptotis meridensis, a taxon not previously examined in recent phylogenies, is rooted at the base of the branch leading to the C. mexicana group of species. The position of this species suggests that the mostly South American C. thomasi group shares an early ancestor with the C. mexicana group.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Morphology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/jmor.10367","issn":"03622525","usgsCitation":"Woodman, N., and Morgan, J., 2005, Skeletal morphology of the forefoot in shrews (Mammalia: Soricidae) of the genus Cryptotis, as revealed by digital x-rays: Journal of Morphology, v. 266, no. 1, p. 60-73, https://doi.org/10.1002/jmor.10367.","startPage":"60","endPage":"73","numberOfPages":"14","costCenters":[],"links":[{"id":237964,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210893,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jmor.10367"}],"volume":"266","issue":"1","noUsgsAuthors":false,"publicationDate":"2005-08-24","publicationStatus":"PW","scienceBaseUri":"505b9127e4b08c986b31978f","contributors":{"authors":[{"text":"Woodman, N. 0000-0003-2689-7373","orcid":"https://orcid.org/0000-0003-2689-7373","contributorId":104176,"corporation":false,"usgs":true,"family":"Woodman","given":"N.","affiliations":[],"preferred":false,"id":415404,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morgan, J.J.P.","contributorId":66052,"corporation":false,"usgs":true,"family":"Morgan","given":"J.J.P.","email":"","affiliations":[],"preferred":false,"id":415403,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70027824,"text":"70027824 - 2005 - Regulation of sand transport in the Colorado River by changes in the surface grain size of eddy sandbars over multi-year timescales","interactions":[],"lastModifiedDate":"2012-03-12T17:21:18","indexId":"70027824","displayToPublicDate":"2005-01-01T00:00:00","publicationYear":"2005","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3369,"text":"Sedimentology","active":true,"publicationSubtype":{"id":10}},"title":"Regulation of sand transport in the Colorado River by changes in the surface grain size of eddy sandbars over multi-year timescales","docAbstract":"In settings where the transport of sand is partially or fully supply limited, changes in the upstream supply of sand are coupled to changes in the grain size of sand on the bed. In this manner, the transport of sand under the supply-limited case is 'grain-size regulated'. Since the closure of Glen Canyon Dam in 1963, the downstream reach of the Colorado River in Marble and Grand Canyons has exhibited evidence of sand-supply limitation. Sand transport in the river is now approximately equally regulated by changes in the discharge of water and changes in the grain sizes of sand on the channel bed and eddy sandbars. Previous work has shown that changes in the grain size of sand on the bed of the channel (driven by changes in the upstream supply of sand owing to both tributary floods and high dam releases) are important in regulating sand transport over timescales of days to months. In this study, suspended-sand data are analysed in conjunction with bed grain-size data to determine whether changes in the grain size of sand on the bed of the channel or changes in the grain size of sand on the surface of eddy sandbars have been more important in regulating sand transport in the post-dam Colorado River over longer, multi-year timescales. The results of this study show that this combined theory- and field-based approach can be used to deduce which environments in a complicated setting are the most important environments for regulating sediment transport. In the case of the regulated Colorado River in Marble and Upper Grand Canyons, suspended-sand transport has been regulated mostly by changes in the surface grain size of eddy sandbars. ?? 2005 International Association of Sedimentologists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Sedimentology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-3091.2005.00738.x","issn":"00370746","usgsCitation":"Topping, D., Rubin, D.M., and Schmidt, J.C., 2005, Regulation of sand transport in the Colorado River by changes in the surface grain size of eddy sandbars over multi-year timescales: Sedimentology, v. 52, no. 5, p. 1133-1153, https://doi.org/10.1111/j.1365-3091.2005.00738.x.","startPage":"1133","endPage":"1153","numberOfPages":"21","costCenters":[],"links":[{"id":211253,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-3091.2005.00738.x"},{"id":238509,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"5","noUsgsAuthors":false,"publicationDate":"2005-09-07","publicationStatus":"PW","scienceBaseUri":"50e4a5f8e4b0e8fec6cdc040","contributors":{"authors":[{"text":"Topping, D.J. 0000-0002-2104-4577","orcid":"https://orcid.org/0000-0002-2104-4577","contributorId":53927,"corporation":false,"usgs":true,"family":"Topping","given":"D.J.","affiliations":[],"preferred":false,"id":415400,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rubin, D.

Combined use of these isotopes may be a useful tool in identifying NO3 sources because NO3 and B co-migrate in many environmental settings, their isotopes are fractionated by different environmental processes, and because wastewater and fertilizers may have distinct isotopic signatures for N and B. The principal cause of elevated NO3 concentrations in residential parts of the study area is wastewater and not natural NO3 or fertilizers. This is indicated by some samples with elevated NO3 concentrations plotting along ??15NNO3 and NO3 mixing lines between natural NO3 from the study area and theoretical septic-system effluent. This conclusion is supported by the presence of caffeine in one sample and the absence of samples with elevated NO3 concentrations that fall along mixing lines between natural NO3 and theoretical percolate below fertilized lawns. Nitrogen isotopes alone could not be used to determine NO3 sources in several wells because denitrification blurred the original isotopic signatures. The range of ??11B values in native ground water in the study area (-8.2??? to +21.2???) is large. The samples with the low ??11B values have a geochemical signature characteristic of hydrothermal systems. Physical and chemical data suggest B is not being strongly fractionated by adsorption onto clays. ??11B values from local STP effluent (-2.7???) and wash water from a domestic washing machine (-5.7???) were used to plot mixing lines between wastewater and native ground water. In general, wells with elevated NO3 concentrations fell along mixing lines between wastewater and background water on plots of ??11B against 1/B and Cl/B.

After accounting for radar penetration depth and predicted surface changes, including effects due to ice mass balance, solid Earth tides, and glacial isostatic adjustment, in part to account for the eight-year data acquisition discrepancy, the resulting difference between the DEM and ICESat profiles is -0.57 ?? 5.88 m. After removing the discrepancy between the DEM and ICESat profiles for a final combined DEM using a bicubic spline, the overall difference is 0.05 ?? 1.35 m. ?? 2005 IEEE.

Experiments were carried out using three NOMs with different physical/chemical properties. For each of the materials, inhibition was found to be more effective at lower carbonate/calcium ratios and lower pH values. The reduction in the precipitation rate could be explained by a Langmuir adsorption model using a conditional equilibrium constant. By identification of the type of site on the NOM molecules that is involved in the adsorption reaction, the \"conditional\" equilibrium constants obtained at different solution compositions converged to a single \"nonconditional\" value. The thermodynamic data determined at 25??C and 1 atm suggest that the interaction between NOM molecules and the calcite surface is chemisorptive in nature and that adsorption is an endothermic reaction driven by the entropy change. The greatest degree of inhibition was observed for the NOM with the highest molecular weight and aromatic carbon content. For a given type of NOM, the degree of inhibition of calcite precipitation was dictated by the balance between the enthalpy change and the entropy change of the adsorption reaction. ?? 2005 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es050470z","issn":"0013936X","usgsCitation":"Lin, Y., Singer, P., and Aiken, G., 2005, Inhibition of calcite precipitation by natural organic material: Kinetics, mechanism, and thermodynamics: Environmental Science & Technology, v. 39, no. 17, p. 6420-6428, https://doi.org/10.1021/es050470z.","startPage":"6420","endPage":"6428","numberOfPages":"9","costCenters":[],"links":[{"id":211101,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es050470z"},{"id":238284,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"39","issue":"17","noUsgsAuthors":false,"publicationDate":"2005-07-27","publicationStatus":"PW","scienceBaseUri":"505a3bd6e4b0c8380cd62872","contributors":{"authors":[{"text":"Lin, Y.-P.","contributorId":62822,"corporation":false,"usgs":true,"family":"Lin","given":"Y.-P.","email":"","affiliations":[],"preferred":false,"id":415311,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Singer, P.C.","contributorId":80424,"corporation":false,"usgs":true,"family":"Singer","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":415312,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Aiken, G.

We used Akaike's information criterion to assess the time interval for averaging observations that was best for estimating vital rates for our study, given our yearly sample sizes. The temporal symmetry approach allowed us to directly assess population growth and to address all losses and gains to the population by using only capture data, offering an alternative to the logistically intensive collection of reproductive data. Models that averaged survival and fertility across 5- and 7-year time intervals were best supported by our data. Studies of black bear populations with annual sample sizes similar to ours should be of at least 5 years in duration to estimate vital rates reliably, and at least 10 years in duration to evaluate changes in population growth rate (??). We also hypothesized that survival would not track changes in ?? because ?? is influenced by both survival and fertility. The 5-year model supported our hypothesis, but the 7-year model did not. Where long-term dynamics of large, relatively stable bear populations are of interest, monitoring survival is likely to be sufficient for evaluating trends in ??.

This basin is unequivocally found to be affected by high aerosols optical depth (AOD) (>0.6) throughout the year. Himalayas restricts movement of aerosols toward north and as a result dynamic nature of aerosol is seen over the Ganga basin. High AOD in this region has detrimental effects on health of more than 460 million people living in this part of India besides adversely affecting clouds formation, monsoonal rainfall pattern and Normalized Difference Vegetation Index (NDVI). Severe drought events (year 2002) in Ganga basin and unexpected failure of monsoon several times, occurred in different parts of Indian subcontinent. Significant rise in AOD (18.7%) over the central part of basin (Kanpur region) have been found to cause substantial decrease in NDVI (8.1%) since 2000. A negative relationship is observed between AOD and NDVI, magnitude of which differs from region to region. Efforts have been made to determine general distribution of AOD and its dominant departure in recent years spatially using Moderate Resolution Imaging Spectroradiometer (MODIS) data. The seasonal changes in aerosol optical depth over the Indo-Gangetic basin is found to very significant as a result of the increasing dust storm events in recent years. ?? 2005 IEEE.","largerWorkTitle":"Proceedings of the Third International Workshop on the Analysis of Multi-Temporal Remote Sensing Images 2005","conferenceTitle":"3rd International Workshop on the Analysis of Multi-Temporal Remote Sensing Images 2005","conferenceDate":"16 May 2005 through 18 May 2005","conferenceLocation":"Biloxi, MS","language":"English","doi":"10.1109/AMTRSI.2005.1469835","isbn":"0780391187; 9780780391185","usgsCitation":"Prasad, A., Singh, R., Singh, A., and Kafatos, M., 2005, Seasonal variability of aerosol optical depth over Indian subcontinent, in Proceedings of the Third International Workshop on the Analysis of Multi-Temporal Remote Sensing Images 2005, v. 2005, Biloxi, MS, 16 May 2005 through 18 May 2005, p. 35-38, https://doi.org/10.1109/AMTRSI.2005.1469835.","startPage":"35","endPage":"38","numberOfPages":"4","costCenters":[],"links":[{"id":211052,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/AMTRSI.2005.1469835"},{"id":238211,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2005","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b88e4e4b08c986b316c0d","contributors":{"authors":[{"text":"Prasad, A.K.","contributorId":86956,"corporation":false,"usgs":true,"family":"Prasad","given":"A.K.","email":"","affiliations":[],"preferred":false,"id":415293,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Singh, R.P.","contributorId":68095,"corporation":false,"usgs":true,"family":"Singh","given":"R.P.","email":"","affiliations":[],"preferred":false,"id":415292,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Singh, A.","contributorId":61211,"corporation":false,"usgs":true,"family":"Singh","given":"A.","affiliations":[],"preferred":false,"id":415291,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kafatos, M.","contributorId":23753,"corporation":false,"usgs":true,"family":"Kafatos","given":"M.","email":"","affiliations":[],"preferred":false,"id":415290,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70027796,"text":"70027796 - 2005 - A predictive penetrative fracture mapping method from regional potential field and geologic datasets, southwest Colorado Plateau, U.S.A.","interactions":[],"lastModifiedDate":"2021-07-02T15:52:39.886114","indexId":"70027796","displayToPublicDate":"2005-01-01T00:00:00","publicationYear":"2005","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1430,"text":"Earth, Planets and Space","active":true,"publicationSubtype":{"id":10}},"title":"A predictive penetrative fracture mapping method from regional potential field and geologic datasets, southwest Colorado Plateau, U.S.A.","docAbstract":"Some aquifers of the southwest Colorado Plateau, U.S.A., are deeply buried and overlain by several impermeable units, and thus recharge to the aquifer is probably mainly by seepage down penetrative fracture systems. This purpose of this study was to develop a method to map the location of candidate deep penetrative fractures over a 120,000 km2 area using gravity and aeromagnetic anomaly data together with surficial fracture data. The resulting database constitutes a spatially registered estimate of recharge location. Candidate deep fractures were obtained by spatial correlation of horizontal gradient and analytic signal maxima of gravity and magnetic anomalies vertically with major surficial lineaments obtained from geologic, topographic, side-looking airborne radar, and satellite imagery. The maps define a sub-set of possible penetrative fractures because of limitations of data coverage and the analysis technique. The data and techniques employed do not yield any indication as to whether fractures are open or closed. Correlations were carried out using image processing software in such a way that every pixel on the resulting grids was coded to uniquely identify which datasets correlated. The technique correctly identified known deep fracture systems and many new ones. Maps of the correlations also define in detail the tectonic fabrics of the southwestern Colorado Plateau.

With radiomarked wolves, the count is straightforward but estimation of the area is more difficult and often given inadequate attention. The population area, based on the mosaic of pack territories, is influenced by sampling intensity similar to the estimation of individual home ranges. If sampling intensity is low, population area will be underestimated and wolf density will be inflated. Using data from studies in Denali National Park and Preserve, Alaska, we investigated these relationships using Monte Carlo simulation to evaluate effects of radiolocation effort and number of marked packs on density estimation. As the number of adjoining pack home ranges increased, fewer relocations were necessary to define a given percentage of population area. We present recommendations for monitoring wolves via radiotelemetry.

The lower Paleozoic (Cambrian to Mississippian) aquifer systems in Kansas, Missouri, and Oklahoma comprise one of the largest regional-scale saline aquifer systems in North America. Understanding hydrologic conditions and processes of these regional-scale aquifer systems provides insight to the evolution of the various sedimentary basins, migration of hydrocarbons out of the Anadarko and Arkoma basins, and the distribution of Arbuckle petroleum reservoirs across Kansas and provides a basis to evaluate CO2 sequestration potential. The Cambrian and Ordovician stratigraphic units form a saline aquifer that is in hydrologic continuity with the freshwater recharge from the Ozark plateau and along the Nemaha anticline.

Landcover classes followed that of the National Oceanic and Atmospheric Administration's Coastal Change Analysis Program; however, classification methods needed to be developed to meet these national standards. Our first classification was limited to the Mermentau River Basin (MRB) in southcentral Louisiana, and the years of 1990, 1993, and 1996. To overcome problems due to class spectral inseparable, spatial and spectra continuums, mixed landcovers, and abnormal transitions, we separated the coastal area into regions of commonality and applying masks to specific land mixtures. Over the three years and 14 landcover classes (aggregating the cultivated land and grassland, and water and floating vegetation classes), overall accuracies ranged from 82% to 90%. To enhance landcover change interpretation, three indicators were introduced as Location Stability, Residence stability, and Turnover. Implementing methods substantiated in the multiple date MRB classification, we spatially extended the classification to the entire Louisiana coast and temporally extended the original 1990, 1993, 1996 classifications to 1999 (Figure 1). We also advanced the operational functionality of the classification and increased the credibility of change detection results. Increased operational functionality that resulted in diminished user input was for the most part gained by implementing a classification logic based on forbidden transitions. The logic detected and corrected misclassifications and mostly alleviated the necessity of subregion separation prior to the classification. The new methods provided an improved ability for more timely detection and response to landcover impact. ?? 2005 IEEE.","largerWorkTitle":"Proceedings of the Third International Workshop on the Analysis of Multi-Temporal Remote Sensing Images 2005","conferenceTitle":"3rd International Workshop on the Analysis of Multi-Temporal Remote Sensing Images 2005","conferenceDate":"16 May 2005 through 18 May 2005","conferenceLocation":"Biloxi, MS","language":"English","doi":"10.1109/AMTRSI.2005.1469881","isbn":"0780391187; 9780780391185","usgsCitation":"Nelson, G., Ramsey, E., and Rangoonwala, A., 2005, Mapping and improving frequency, accuracy, and interpretation of land cover change: Classifying coastal Louisiana with 1990, 1993, 1996, and 1999 Landsat Thematic Mapper image data, in Proceedings of the Third International Workshop on the Analysis of Multi-Temporal Remote Sensing Images 2005, v. 2005, Biloxi, MS, 16 May 2005 through 18 May 2005, p. 241-243, https://doi.org/10.1109/AMTRSI.2005.1469881.","startPage":"241","endPage":"243","numberOfPages":"3","costCenters":[],"links":[{"id":211178,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/AMTRSI.2005.1469881"},{"id":238395,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2005","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a504ee4b0c8380cd6b5c4","contributors":{"authors":[{"text":"Nelson, G.","contributorId":101072,"corporation":false,"usgs":true,"family":"Nelson","given":"G.","affiliations":[],"preferred":false,"id":415176,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ramsey, Elijah W.

Detailed hydrogeologic characterization completed at a small study site in a densely fractured dolomite has yielded an extensive data set that was used to evaluate the utility of the continuum and discrete-fracture approaches to aquifer characterization. There are two near-vertical sets of fractures at the site; near-horizontal bedding-plane partings constitute a third fracture set. Eighteen boreholes, including five coreholes, were drilled to a depth of ???10.6 m. Borehole geophysical logs revealed several laterally extensive horizontal fractures and dissolution zones. Flowmeter and short-interval packer testing identified which of these features were hydraulically important. A monitoring system, consisting of short-interval piezometers and multilevel samplers, was designed to monitor four horizontal fractures and two dissolution zones. The resulting network consisted of >70 sampling points and allowed detailed monitoring of head distributions in three dimensions. Comparison of distributions of hydraulic head - and hydraulic conductivity determined by these two approaches suggests that even in a densely fractured-carbonate aquifer, a characterization approach using traditional long-interval monitoring wells is inadequate to characterize ground water movement for the purposes of regulatory monitoring or site remediation. In addition, traditional multiwell pumping tests yield an average or bulk hydraulic conductivity that is not adequate for predicting rapid ground water travel times through the fracture network, and the pumping test response does not appear to be an adequate tool for assessing whether the porous medium approximation is valid.

Extensive urbanization has altered the geomorphology and hydrology of the streams, adversely affecting aquatic communities. We studied macroinvertebrate and periphyton assemblages in relation to two categorical features of the highly engineered hydrologic system-water source and channel type. Four water sources were identified-natural, urban-impacted groundwater, urban runoff, and treated wastewater. Three channel types were identified-natural, channelized with natural bottom, and concrete-lined. Nineteen sites, covering the range of these two categorical features, were sampled in summer 2000. To minimize the effects of different substrate types among sites, artificial substrates were used for assessing macroinvertebrate and periphyton assemblages. Physical and chemical variables and metrics calculated from macroinvertebrate and periphyton assemblage data were compared among water sources and channel types using analysis of variance and multiple comparison tests. Macroinvertebrate metrics exhibiting significant (P < 0.05) differences between water sources included taxa and Ephemeroptera-Plecoptera-Trichoptera richness, relative richness and abundance of nonchironomid dipterans, orthoclads, oligochaetes, and some functional-feeding groups such as parasites and shredders. Periphyton metrics showing significant differences between water sources included blue-green algae biovolume and relative abundance of nitrogen heterotrophic, eutrophic, motile, and pollution-sensitive diatoms. The relative abundance of trichopterans, tanytarsini chironomids, noninsects, and filter feeders, as well as the relative richness and abundance of diatoms, were significantly different between channel types. Most physical variables were related to channel type, whereas chemical variables and some physical variables (e.g., discharge, velocity, and channel width) were related to water source. These associations were reflected in correlations between metrics, chemical variables, and physical variables. Significant improvements in the aquatic ecosystem of the Santa Ana River basin are possible with management actions such as conversion of concrete-lined channels to channelized streams with natural bottoms that can still maintain flood control to protect life and property.","language":"English","publisher":"American Fisheries Society","issn":"08922284","usgsCitation":"Burton, C.A., Brown, L.R., and Belitz, K., 2005, Assessing water source and channel type as factors affecting benthic macroinvertebrate and periphyton assemblages in the highly urbanized Santa Ana River Basin, California: American Fisheries Society Symposium, v. 2005, no. 47, p. 239-262.","productDescription":"24 p.","startPage":"239","endPage":"262","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":238245,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2005","issue":"47","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059edf5e4b0c8380cd49b36","contributors":{"authors":[{"text":"Burton, Carmen A. 0000-0002-6381-8833 caburton@usgs.gov","orcid":"https://orcid.org/0000-0002-6381-8833","contributorId":444,"corporation":false,"usgs":true,"family":"Burton","given":"Carmen","email":"caburton@usgs.gov","middleInitial":"A.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":415138,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brown, Larry R. 0000-0001-6702-4531 lrbrown@usgs.gov","orcid":"https://orcid.org/0000-0001-6702-4531","contributorId":1717,"corporation":false,"usgs":true,"family":"Brown","given":"Larry","email":"lrbrown@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":415137,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Belitz, Kenneth 0000-0003-4481-2345 kbelitz@usgs.gov","orcid":"https://orcid.org/0000-0003-4481-2345","contributorId":442,"corporation":false,"usgs":true,"family":"Belitz","given":"Kenneth","email":"kbelitz@usgs.gov","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true},{"id":503,"text":"Office of Water Quality","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true}],"preferred":true,"id":415136,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70027763,"text":"70027763 - 2005 - The evolution of fledging age in songbirds","interactions":[],"lastModifiedDate":"2012-03-12T17:20:50","indexId":"70027763","displayToPublicDate":"2005-01-01T00:00:00","publicationYear":"2005","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2273,"text":"Journal of Evolutionary Biology","active":true,"publicationSubtype":{"id":10}},"title":"The evolution of fledging age in songbirds","docAbstract":"In birds with altricial young an important stage in the life history is the age at fledging. In this paper we use an approach proven successful in the prediction of the optimal age at maturity in fish and reptiles to predict the optimal age of fledging in passerines. Integrating the effects of growth on future fecundity and survival leads to the prediction that the optimal age at fledging is given by a function that comprises survival to maturity, the exponent of the fecundity-body size relationship and nestling growth. Growth is described by the logistic equation with parameters, A, K and ti. Assuming that the transitional mortality curve can be approximated by the nestling mortality, Mn, the optimal fledging age, tf, is given by a simple formula involving the three growth parameters, nestling mortality (Mn) and the exponent (d) of the fecundity-body size relationship. Predictions of this equation underestimate the true values by 11-16%, which is expected as a consequence of the transitional mortality function approximation. A transitional mortality function in which mortality is approximately 0.3-0.4 of nesting mortality (i.e. mortality declines rapidly after fledging) produces predictions which, on average, equal the observed values. Data are presented showing that mortality does indeed decline rapidly upon fledging. ?? 2005 European Society for Evolutionary Biology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Evolutionary Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1420-9101.2005.00958.x","issn":"1010061X","usgsCitation":"Roff, D., Remes, V., and Martin, T.E., 2005, The evolution of fledging age in songbirds: Journal of Evolutionary Biology, v. 18, no. 6, p. 1425-1433, https://doi.org/10.1111/j.1420-9101.2005.00958.x.","startPage":"1425","endPage":"1433","numberOfPages":"9","costCenters":[],"links":[{"id":477922,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1420-9101.2005.00958.x","text":"Publisher Index Page"},{"id":211007,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1420-9101.2005.00958.x"},{"id":238142,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"6","noUsgsAuthors":false,"publicationDate":"2005-10-12","publicationStatus":"PW","scienceBaseUri":"505babe2e4b08c986b32313a","contributors":{"authors":[{"text":"Roff, D.A.","contributorId":86963,"corporation":false,"usgs":true,"family":"Roff","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":415117,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Remes, V.","contributorId":72584,"corporation":false,"usgs":true,"family":"Remes","given":"V.","email":"","affiliations":[],"preferred":false,"id":415116,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Martin, T.
