We used demographic data from 16 673 trees in 15 permanent plots to create 17 separate time-invariant, density-independent population projection models, and determined differences between trends projected from initial surveys with a 5-year interval and observed data during two subsequent 5-year time steps. 2 We detected departures from the assumptions of the matrix modelling approach in terms of strong growth autocorrelations. We also found evidence of observation errors for measurements of tree growth and, to a more limited degree, recruitment. Loglinear analysis provided evidence of significant temporal variation in demographic rates for only two of the 17 populations. 3 Total population sizes were strongly predicted by model projections, although population dynamics were dominated by carryover from the previous 5-year time step (i.e. there were few cases of recruitment or death). Fractional changes to overall population sizes were less well predicted. Compared with a null model and a simple demographic model lacking size structure, matrix model projections were better able to predict total population sizes, although the differences were not statistically significant. Matrix model projections were also able to predict short-term rates of survival, growth and recruitment. Mortality frequencies were not well predicted. 4 Our results suggest that simple size-structured models can accurately project future short-term changes for some tree populations. However, not all populations were well predicted and these simple models would probably become more inaccurate over longer projection intervals. The predictive ability of these models would also be limited by disturbance or other events that destabilize demographic rates. ?? 2005 British Ecological Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2745.2005.01007.x","issn":"00220477","usgsCitation":"van Mantgem, P.J., and Stephenson, N., 2005, The accuracy of matrix population model projections for coniferous trees in the Sierra Nevada, California: Journal of Ecology, v. 93, no. 4, p. 737-747, https://doi.org/10.1111/j.1365-2745.2005.01007.x.","startPage":"737","endPage":"747","numberOfPages":"11","costCenters":[],"links":[{"id":212564,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2745.2005.01007.x"},{"id":240066,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"93","issue":"4","noUsgsAuthors":false,"publicationDate":"2005-05-03","publicationStatus":"PW","scienceBaseUri":"505ba99ce4b08c986b3223a7","contributors":{"authors":[{"text":"van Mantgem, P.

Data from uncontaminated forests were used to provide estimates of background mutation rates. We also determined whether other fitness parameters were negatively correlated with mutagenic stress (e.g., degree of outcrossing and numbers of reproducing trees km-1). Contaminated sites in Tampa Bay had significantly higher frequencies of trees that were heterozygous for albinism per 1000 total reproducing trees (FHT) than uncontaminated forests (mean ?? SE: 11.4 ?? 4.3 vs 4.3 ?? 0.73, P<0.022). Two sites that were contaminated by oil failed to show elevated FHT, although in the first instance, the mutagenic effects of the oil may have been reduced by several weeks of weathering in open water before coming ashore, and in the second > 25 yrs of subsequent recruitment and tree replacement may have allowed an initial elevation in the FHT to decay. Patterns of FHT were not explained by distance from the bay mouth or the degree of urbanization. However, there was a significant positive relationship between tree size and FHT (r=0.83, P<0.018), which suggests that forests with older or larger trees provide a more lasting record of cumulative mutagenic stress. No other fitness parameters correlated with FHT. There was a difference in FHT between two latitudes, as determined by comparing Tampa Bay with literature values for Puerto Rico. The sensitivity of this bioassay for the effects of mutagens will facilitate future monitoring of contamination events and comparisons of bay-wide recovery in future decades. Development of a database of FHT values for a range of subtropical and tropical estuaries is underway that will provide a baseline against which to compare mutational consequences of global change. ?? 2005, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/9","issn":"02775212","usgsCitation":"Proffitt, C., and Travis, S., 2005, Albino mutation rates in red mangroves (Rhizophora mangle L.) as a bioassay of contamination history in Tampa Bay, Florida, USA: Wetlands, v. 25, no. 2, p. 326-334, https://doi.org/10.1672/9.","startPage":"326","endPage":"334","numberOfPages":"9","costCenters":[],"links":[{"id":212246,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/9"},{"id":239706,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e955e4b0c8380cd481f3","contributors":{"authors":[{"text":"Proffitt, C.E. 0000-0002-0845-8441","orcid":"https://orcid.org/0000-0002-0845-8441","contributorId":47339,"corporation":false,"usgs":true,"family":"Proffitt","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":432475,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Travis, S.E. 0000-0001-9338-8953","orcid":"https://orcid.org/0000-0001-9338-8953","contributorId":28718,"corporation":false,"usgs":true,"family":"Travis","given":"S.E.","email":"","affiliations":[],"preferred":false,"id":432474,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Utilizing Web-based technologies, the Colorado Geological Survey's Colorado Late Cenozoic Fault and Fold Database was transformed from a monothematic, nonspatial Microsoft Access database into a complex information set incorporating multiple data sources. The resulting user-friendly format supports easy analysis and browsing. The core of the application is the Microsoft Access database, which contains information compiled from available literature about faults and folds that are known or suspected to have moved during the late Cenozoic. The database contains nonspatial fields such as structure type, age, and rate of movement. Geographic locations of the fault and fold traces were compiled from previous studies at 1:250,000 scale to form a spatial database containing information such as length and strike. Integration of the two databases allowed both spatial and nonspatial information to be presented on the Internet as a single dataset (http://geosurvey.state.co.us/pubs/ceno/). The user-friendly interface enables users to view and query the data in an integrated manner, thus providing multiple ways to locate desired information. Retaining the digital data format also allows continuous data updating and quick delivery of newly acquired information. This dataset is a valuable resource to anyone interested in earthquake hazards and the activity of faults and folds in Colorado. Additional geologic hazard layers and imagery may aid in decision support and hazard evaluation.

The fault varies in strike from northwest to west. In its westernmost section, the fault is ∼500 m south of an abrupt, curvilinear mountain front separating the 270- to 361-m-high La Cadena de San Francisco range from the Rio Añasco alluvial valley. The Quaternary fault of the Añasco Valley is in alignment with the bedrock fault mapped by D. McIntyre (1971) in the Central La Plata quadrangle sheet east of Añasco Valley. Previous workers have postulated that the Cerro Goden fault zone continues southeast from the Añasco Valley and merges with the Great Southern Puerto Rico fault zone of south-central Puerto Rico. West of the Añasco Valley, the fault continues offshore into the Mona Passage (Caribbean Sea) where it is characterized by offsets of seafloor sediments estimated to be of late Quaternary age. Using both 1:18,500 scale air photographs taken in 1936 and 1:40,000 scale photographs taken by the U.S. Department of Agriculture in 1986, we identified geomorphic features suggestive of Quaternary fault movement in the Añasco Valley, including aligned and deflected drainages, apparently offset terrace risers, and mountain-facing scarps. Many of these features suggest right-lateral displacement.</p><p>Mapping of Paleogene bedrock units in the uplifted La Cadena range adjacent to the Cerro Goden fault zone reveals the main tectonic events that have culminated in late Quaternary normal-oblique displacement across the Cerro Goden fault. Cretaceous to Eocene rocks of the La Cadena range exhibit large folds with wavelengths of several kms. The orientation of folds and analysis of fault striations within the folds indicate that the folds formed by northeast-southwest shortening in present-day geographic coordinates. The age of deformation is well constrained as late Eocene–early Oligocene by an angular unconformity separating folded, deep-marine middle Eocene rocks from transgressive, shallow-marine rocks of middle-upper Oligocene age. Rocks of middle Oligocene–early Pliocene age above unconformity are gently folded about the roughly east-west–trending Puerto Rico–Virgin Islands arch, which is well expressed in the geomorphology of western Puerto Rico. Arching appears ongoing because onshore and offshore late Quaternary oblique-slip faults closely parallel the complexly deformed crest of the arch and appear to be related to extensional strains focused in the crest of the arch. We estimate ∼4 km of vertical throw on the Cerro Goden fault based on the position of the carbonate cap north of the fault in the La Cadena de San Francisco and its position south of the fault inferred from seismic reflection data in Mayaguez Bay. Based on these observations, our interpretation of the kinematics and history of the Cerro Goden fault zone includes two major phases of motion: (1) Eocene northeast-southwest shortening possibly accompanied by left-lateral shearing as determined by previous workers on the Great Southern Puerto Rico fault zone; and (2) post–early Pliocene regional arching of Puerto Rico accompanied by normal offset and right-lateral shear along faults flanking the crest of the arch. The second phase of deformation accompanied east-west opening of the Mona rift and is inferred to continue to the present day.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0-8137-2385-X.115","usgsCitation":"Mann, P., Prentice, C., Hippolyte, J., Grindlay, N., Abrams, L., and Lao-Davila, D., 2005, Reconnaissance study of late quaternary faulting along Cerro Goden fault zone, western Puerto Rico: Special Paper of the Geological Society of America, v. 385, p. 115-137, https://doi.org/10.1130/0-8137-2385-X.115.","productDescription":"23 p.","startPage":"115","endPage":"137","numberOfPages":"23","costCenters":[],"links":[{"id":243175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Puerto Rico","otherGeospatial":"Cerro Goden fault zone","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -67.3187255859375,\n              17.926475979176438\n            ],\n            [\n              -66.33270263671875,\n              17.926475979176438\n            ],\n            [\n              -66.33270263671875,\n              18.521283325496277\n            ],\n            [\n              -67.3187255859375,\n              18.521283325496277\n            ],\n            [\n              -67.3187255859375,\n              17.926475979176438\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"385","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9913e4b0c8380cd82d6f","contributors":{"authors":[{"text":"Mann, P.","contributorId":55167,"corporation":false,"usgs":true,"family":"Mann","given":"P.","email":"","affiliations":[],"preferred":false,"id":450576,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Prentice, C.S.","contributorId":56667,"corporation":false,"usgs":true,"family":"Prentice","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":450577,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hippolyte, J.-C.","contributorId":36377,"corporation":false,"usgs":true,"family":"Hippolyte","given":"J.-C.","email":"","affiliations":[],"preferred":false,"id":450574,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Grindlay, N.R.","contributorId":28445,"corporation":false,"usgs":true,"family":"Grindlay","given":"N.R.","email":"","affiliations":[],"preferred":false,"id":450573,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Abrams, L.J.","contributorId":98968,"corporation":false,"usgs":true,"family":"Abrams","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":450578,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lao-Davila, D.","contributorId":44753,"corporation":false,"usgs":true,"family":"Lao-Davila","given":"D.","email":"","affiliations":[],"preferred":false,"id":450575,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Extensive urbanization has created substantial change to the region's landscape and ecosystems. This paper uses a dynamic urban-growth model, SLEUTH, which applies six geospatial data themes (slope, land use, exclusion, urban extent, transportation, hillside), to study the process of urbanization and associated land use and land cover change in the Tampa Bay area. To reduce processing time and complete the modeling process within an acceptable period, the model is recoded and ported to a Beowulf cluster. The parallel-processing computer system accomplishes the massive amount of computation the modeling simulation requires.

The objectives of this study were to assess the population structure and gene flow patterns among migratory sandhill cranes using microsatellite DNA genotypes and mitochondrial DNA haplotypes of a large sample of individuals across three populations. In particular, we were interested in evaluating the roles of Pleistocene glaciation events and postglaciation gene flow in shaping the present-day population structure. Our results indicate substantial gene flow across regions of the Midcontinental population that are geographically adjacent, suggesting that gene flow for most of the region follows an isolation-by-distance model. Male-mediated gene flow and strong female philopatry may explain the differing patterns of nuclear and mitochondrial variation. Taken in context with precise geographical information on breeding locations, the morphologic and microsatellite DNA variation shows a gradation from the Arctic-nesting subspecies G. c. canadensis to the non-Arctic subspecies G. c. tabida. Analogous to other Arctic-nesting birds, it is probable that the population structure seen in Midcontinental sandhill cranes reflects the result of post-glacial secondary contact. Our data suggest that subspecies of migratory sandhills experience significant gene flow and therefore do not represent distinct and independent genetic entities. ??2005 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Molecular Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-294X.2005.02622.x","issn":"09621083","usgsCitation":"Jones, K., Krapu, G., Brandt, D., and Ashley, M., 2005, Population genetic structure in migratory sandhill cranes and the role of Pleistocene glaciations: Molecular Ecology, v. 14, no. 9, p. 2645-2657, https://doi.org/10.1111/j.1365-294X.2005.02622.x.","productDescription":"13 p.","startPage":"2645","endPage":"2657","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":240133,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212619,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-294X.2005.02622.x"}],"volume":"14","issue":"9","noUsgsAuthors":false,"publicationDate":"2005-06-13","publicationStatus":"PW","scienceBaseUri":"505a7d73e4b0c8380cd79f5f","contributors":{"authors":[{"text":"Jones, K.L.","contributorId":102024,"corporation":false,"usgs":true,"family":"Jones","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":431305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Krapu, Gary L.","contributorId":56994,"corporation":false,"usgs":true,"family":"Krapu","given":"Gary L.","affiliations":[],"preferred":false,"id":431303,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brandt, D.A.","contributorId":67448,"corporation":false,"usgs":true,"family":"Brandt","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":431304,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ashley, M.V.","contributorId":15556,"corporation":false,"usgs":true,"family":"Ashley","given":"M.V.","email":"","affiliations":[],"preferred":false,"id":431302,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The aim of this study is to investigate the effect of the seasonal distributions of water and energy, and their interactions with the soil moisture store, on mean annual water balance in Australia at catchment scales using a stochastic model of soil moisture balance with seasonally varying forcing. The rainfall regime at 262 catchments around Australia was modeled as a Poisson process with the mean storm arrival rate and the mean storm depth varying throughout the year as cosine curves with annual periods. The soil moisture dynamics were represented by use of a single, finite water store having infinite infiltration capacity, and the potential evapotranspiration rate was modeled as an annual cosine curve. The mean annual water budget was calculated numerically using a Monte Carlo simulation. The model predicted that for a given level of climatic aridity the ratio of mean annual evapotranspiration to rainfall was larger where the potential evapotranspiration and rainfall were in phase, that is, in summer‐dominant rainfall catchments, than where they were out of phase. The observed mean annual evapotranspiration ratios have opposite results. As a result, estimates of mean annual evapotranspiration from the model compared poorly with observational data. Because the inclusion of seasonally varying forcing alone was not sufficient to explain variability in the mean annual water balance, other catchment properties may play a role. Further analysis showed that the water balance was highly sensitive to the catchment‐scale soil moisture capacity. Calibrations of this parameter indicated that infiltration‐excess runoff might be an important process, especially for the summer‐dominant rainfall catchments; most similar studies have shown that modeling of infiltration‐excess runoff is not required at the mean annual timescale.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2004WR003697","usgsCitation":"Potter, N., Zhang, L., Milly, P., McMahon, T., and Jakeman, A., 2005, Effects of rainfall seasonality and soil moisture capacity on mean annual water balance for Australian catchments: Water Resources Research, v. 41, no. 6, Article W06007; 11 p., https://doi.org/10.1029/2004WR003697.","productDescription":"Article W06007; 11 p.","costCenters":[],"links":[{"id":497384,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://admin.research-repository.uwa.edu.au/en/publications/dd5131ba-913b-4ad7-aaa3-51e7f2c4b4a5","text":"External Repository"},{"id":239863,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"6","noUsgsAuthors":false,"publicationDate":"2005-06-09","publicationStatus":"PW","scienceBaseUri":"505a07a8e4b0c8380cd5177d","contributors":{"authors":[{"text":"Potter, N.J.","contributorId":9466,"corporation":false,"usgs":true,"family":"Potter","given":"N.J.","email":"","affiliations":[],"preferred":false,"id":432040,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhang, L.","contributorId":41543,"corporation":false,"usgs":true,"family":"Zhang","given":"L.","email":"","affiliations":[],"preferred":false,"id":432042,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Milly, P.

Two previously analyzed data sets are examined with a focus on the reliability of these RSTMs in characterizing stream and storage zone solute reactions. Sensitivities of simulations to parameters within and among reaches, parameter coefficients of variation, and correlation coefficients are computed and analyzed. Our results indicate that (1) simulated values have the greatest sensitivity to parameters within the same reach, (2) simulated values are also sensitive to parameters in reaches immediately upstream and downstream (inter-reach sensitivity), (3) simulated values have decreasing sensitivity to parameters in reaches farther downstream, and (4) in-stream reactive solute data provide adequate data to resolve effective storage zone reaction parameters, given the model formulations. Simulations of reactive solutes are shown to be equally sensitive to transport parameters and effective reaction parameters of the model, evidence of the control of physical transport on reactive solute dynamics.

Adults of both sexes were collected during the autumn of 2002 in South Africa, and stereological analytical techniques were used to quantify the distribution of testicular cell types. In addition, total laryngeal mass was used as a gauge of secondary sex differences in animals from MGA and NMGA study sites. Evaluation of the total laryngeal mass revealed that there were no statistically significant differences between X. laevis of the same sex from the NMGA and MGA sites. Mean percent fractional-volume values for seminiferous tubule distribution of testicular cell types of mature X. laevis, ranged from 3-4% for spermatogonia, 26-28% for spermatocytes, 54-57% for spermatozoa, and 14-15% for other cells types.

The concept is especially valuable in subjective assessments of future coal production, which would require a detailed understanding of the coal geology and coal chemistry of the region. In addition, subjective assessments of future coal production would be enhanced by a geographical information system that contains the geologic and geochemical data commonly prepared for conventional coal assessments. Coal systems are generally defined as one or more coal beds or groups of coal beds that have had the same or similar genetic history from their inception as peat deposits, through their burial, diagenesis, and epigenesis to their ultimate preservation as lignite, bituminous coal, or anthracite. The central and northern parts of the Appalachian basin contain seven coal systems (Coal Systems A-G). These systems may be defined generally on the following criteria: (1) on the primary characteristics of their paleopeat deposits, (2) on the stratigraphic framework of the Paleozoic coal measures, (3) on the relative abundance of coal beds within the major stratigraphic groupings, (4) on the amount of sulfur related to the geologic and climatic conditions under which paleopeat deposits accumulated, and (5) on the rank of the coal (lignite to anthracite). ??2005 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/0-8137-2387-6.9","issn":"00721077","usgsCitation":"Milici, R.C., 2005, Appalachian coal assessment: Defining the coal systems of the Appalachian basin: Special Paper of the Geological Society of America, no. 387, p. 9-30, https://doi.org/10.1130/0-8137-2387-6.9.","startPage":"9","endPage":"30","numberOfPages":"22","costCenters":[],"links":[{"id":242934,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215156,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0-8137-2387-6.9"}],"issue":"387","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ec76e4b0c8380cd492a6","contributors":{"authors":[{"text":"Milici, R.

In this paper we investigate temporal variability in hydrodynamic roughness using velocity profiles in the bottom boundary layer measured with a high-resolution acoustic Doppler profiler (PCADP). The data were collected on the ebb-tidal delta off Grays Harbor, Washington, in a mean water depth of 9 m. Significant wave height ranged from 0.5 to 3 m. Bottom roughness has rarely been determined from hydrodynamic measurements under conditions such as these, where energetic waves and medium-to-fine sand produce small bedforms. Friction velocity due to current u*c and apparent bottom roughness z0a were determined from the PCADP burst mean velocity profiles using the law of the wall. Bottom roughness kB was estimated by applying the Grant-Madsen model for wave-current interaction iteratively until the model u*c converged with values determined from the data. The resulting kB values ranged over 3 orders of magnitude (10-1 to 10-4 m) and varied inversely with wave orbital diameter. This range of kB influences predicted bottom shear stress considerably, suggesting that the use of time-varying bottom roughness could significantly improve the accuracy of sediment transport models. Bedform height was estimated from kB and is consistent with both ripple heights predicted by empirical models and bedforms in sonar images collected during the experiment.

The wells were screened from 117 to 437 m below land surface, and in most cases, flow from the aquifer into the wells was not uniformly distributed throughout the well screen. Wells having as little as 6 m of screen in the overlying upper aquifer system yielded as much as 50% of their water from the upper system during drought periods, while the deeper parts of the well screens yielded 15% or less of the total yield of the wells. Mixing of water within wells during pumping degraded higher-quality water with poorer-quality water from deeper depths, and in some cases with poorer-quality water from the overlying upper aquifer system. Changes in the mixture of water within a well, resulting from changes in the distribution of flow into the well, changed the quality of water from the surface discharge of wells over time. The combination of flowmeter and depth-dependent water quality data yielded information about sources of high-chloride water to wells that was not available on the basis of samples collected from nearby observation wells.

These patterns of turnover in populations of trees are broadly similar to the patterns of turnover in populations of plant organs (leaves and roots) found in other studies. Our findings suggest a link between forest mass balance and the population dynamics of trees, and have implications for understanding and predicting the effects of environmental changes on forest structure and terrestrial carbon dynamics.&nbsp;</p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1461-0248.2005.00746.x","issn":"1461023X","usgsCitation":"Stephenson, N., and van Mantgem, P.J., 2005, Forest turnover rates follow global and regional patterns of productivity: Ecology Letters, v. 8, no. 5, p. 524-531, https://doi.org/10.1111/j.1461-0248.2005.00746.x.","productDescription":"8 p.","startPage":"524","endPage":"531","numberOfPages":"8","costCenters":[],"links":[{"id":238618,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"5","noUsgsAuthors":false,"publicationDate":"2005-04-11","publicationStatus":"PW","scienceBaseUri":"505a133ae4b0c8380cd54589","contributors":{"authors":[{"text":"Stephenson, N.L.","contributorId":17559,"corporation":false,"usgs":true,"family":"Stephenson","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":430650,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"van Mantgem, P.

The presence of steep slopes in mountainous terrain, coupled with weathered soils and intense rainfall, leads to severe slope-stability problems throughout the island. Episodic triggering events such as hurricanes and earthquakes further exacerbate these problems. All physiographic provinces of the island have experienced landslides. The stability of natural and man-made slopes is a serious concern for government authorities and the civil engineering community in Puerto Rico. This paper presents an overview of the rainfall induced landslide problem in PR, a summary of literature published on this subject, and proposes a rainfall intensity landslide threshold based on landslide events data from 1959 to 2003. This threshold can be used as part of a potential landslide warning system.","largerWorkTitle":"Geotechnical Special Publication","conferenceTitle":"Geo-Frontiers 2005","conferenceDate":"24 January 2005 through 26 January 2005","conferenceLocation":"Austin, TX","language":"English","issn":"08950563","usgsCitation":"Pando, M., Ruiz, M., and Larsen, M.C., 2005, Rainfall-induced landslides in Puerto Rico: An overview, <i>in</i> Geotechnical Special Publication, no. 130-142, Austin, TX, 24 January 2005 through 26 January 2005, p. 2911-2925.","startPage":"2911","endPage":"2925","numberOfPages":"15","costCenters":[],"links":[{"id":239882,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"130-142","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9475e4b0c8380cd81407","contributors":{"authors":[{"text":"Pando, M.A.","contributorId":88953,"corporation":false,"usgs":true,"family":"Pando","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":430836,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ruiz, M.E.","contributorId":52792,"corporation":false,"usgs":true,"family":"Ruiz","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":430834,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Larsen, M.

Knowledge about the timing, severity, and pattern of droughts on the landscape can be incorporated into effective planning and decision-making. In this study, we present a data mining approach to modeling vegetation stress due to drought and mapping its spatial extent during the growing season. Rule-based regression tree models were generated that identify relationships between satellite-derived vegetation conditions, climatic drought indices, and biophysical data, including land-cover type, available soil water capacity, percent of irrigated farm land, and ecological type. The data mining method builds numerical rule-based models that find relationships among the input variables. Because the models can be applied iteratively with input data from previous time periods, the method enables to provide predictions of vegetation conditions farther into the growing season based on earlier conditions. Visualizing the model outputs as mapped information (called VegPredict) provides a means to evaluate the model. We present prototype maps for the 2002 drought year for Nebraska and South Dakota and discuss potential uses for these maps.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.isprsjprs.2005.02.003","issn":"09242716","usgsCitation":"Tadesse, T., Brown, J.F., and Hayes, M., 2005, A new approach for predicting drought-related vegetation stress: Integrating satellite, climate, and biophysical data over the U.S. central plains: ISPRS Journal of Photogrammetry and Remote Sensing, v. 59, no. 4, p. 244-253, https://doi.org/10.1016/j.isprsjprs.2005.02.003.","productDescription":"10 p.","startPage":"244","endPage":"253","numberOfPages":"10","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":212388,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.isprsjprs.2005.02.003"},{"id":239865,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"59","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e49be4b0c8380cd4676f","contributors":{"authors":[{"text":"Tadesse, Tsegaye 0000-0002-4102-1137","orcid":"https://orcid.org/0000-0002-4102-1137","contributorId":147617,"corporation":false,"usgs":false,"family":"Tadesse","given":"Tsegaye","email":"","affiliations":[],"preferred":false,"id":432214,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brown, Jesslyn F. 0000-0002-9976-1998 jfbrown@usgs.gov","orcid":"https://orcid.org/0000-0002-9976-1998","contributorId":3241,"corporation":false,"usgs":true,"family":"Brown","given":"Jesslyn","email":"jfbrown@usgs.gov","middleInitial":"F.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":432212,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hayes, M.J.","contributorId":56855,"corporation":false,"usgs":true,"family":"Hayes","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":432213,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Average pH values at the upstream (F1), middle (F2), and downstream (F3) monitoring stations were 3.31, 5.46, and 6.80, respectively. The downstream increase in pH resulted in precipitation of hydrous ferric oxide (HFO) and hydrous aluminum oxide (HAO) on the streambed. At F1 and F2, Fe showed strong diel cycles in dissolved concentration and Fe(II)/Fe(III) ratio; these cycles were attributed to daytime photoreduction of Fe(III) to Fe(II), reoxidation of Fe(II) to Fe(III), and temperature-dependent hydrolysis and precipitation of HFO. At the near-neutral downstream station, no evidence of Fe(III) photoreduction was observed, and suspended particles of HFO dominated the total Fe load. HFO precipitation rates between F2 and F3 were highest in the afternoon, due in part to reoxidation of a midday pulse of Fe<sup>2+</sup><span>&nbsp;</span>formed by photoreduction in the upper, acidic portions of the stream. Dissolved concentrations of Fe(II) and Cu decreased tenfold and 2.4-fold, respectively, during the day at F3. These changes were attributed to sorption onto fresh HFO surfaces. Results of surface complexation modeling showed good agreement between observed and predicted Cu concentrations at F3, but only when adsorption enthalpies were added to the thermodynamic database to take into account diel temperature variations. The field and modeling results illustrate that the degree to which trace metals adsorb onto actively forming HFO is strongly temperature dependent. This study is an example of how diel Fe cycles caused by redox and hydrolysis reactions can induce a diel cycle in a trace metal of toxicological importance in downstream waters.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2004.11.020","issn":"00167037","usgsCitation":"Gammons, C., Nimick, D., Parker, S., Cleasby, T., and McCleskey, R.B., 2005, Diel behavior of iron and other heavy metals in a mountain stream with acidic to neutral pH: Fisher Creek, Montana, USA: Geochimica et Cosmochimica Acta, v. 69, no. 10, p. 2505-2516, https://doi.org/10.1016/j.gca.2004.11.020.","productDescription":"12 p.","startPage":"2505","endPage":"2516","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":239737,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212275,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2004.11.020"}],"country":"United States","state":"Montana","otherGeospatial":"Fisher Creek","volume":"69","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00bee4b0c8380cd4f8be","contributors":{"authors":[{"text":"Gammons, C.H.","contributorId":18459,"corporation":false,"usgs":true,"family":"Gammons","given":"C.H.","affiliations":[],"preferred":false,"id":432638,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nimick, D.

To address this need, the U.S. Geological Survey (USGS) has developed the Modular Modeling System (MMS). MMS is an integrated system of computer software for model development, integration, and application. Its modular design allows a high level of flexibility and adaptability to enable modelers to incorporate their own software into a rich array of built-in models and modeling tools. These include individual process models, tightly coupled models, loosely coupled models, and fully- integrated decision support systems. A geographic information system (GIS) interface, the USGS GIS Weasel, has been integrated with MMS to enable spatial delineation and characterization of basin and ecosystem features, and to provide objective parameter-estimation methods for models using available digital data. MMS provides optimization and sensitivity-analysis tools to analyze model parameters and evaluate the extent to which uncertainty in model parameters affects uncertainty in simulation results. MMS has been coupled with the Bureau of Reclamation object-oriented reservoir and river-system modeling framework, RiverWare, to develop models to evaluate and apply optimal resource-allocation and management strategies to complex, operational decisions on multipurpose reservoir systems and watersheds. This decision support system approach has been developed, tested, and implemented in the Gunnison, Yakima, San Joaquin, Rio Grande, and Truckee River basins of the western United States. MMS is currently being coupled with the U.S. Forest Service model SIMulating Patterns and Processes at Landscape Scales (SIMPPLLE) to assess the effects of alternative vegetation-management strategies on a variety of hydrological and ecological responses. Initial development and testing of the MMS-SIMPPLLE integration is being conducted on the Colorado Plateau region of the western United Sates.","largerWorkTitle":"Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceTitle":"2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceDate":"19 July 2005 through 22 July 2005","conferenceLocation":"Williamsburg, VA","language":"English","isbn":"0784407630","usgsCitation":"Leavesley, G., Markstrom, S., Viger, R., and Hay, L., 2005, The Modular Modeling System (MMS): A toolbox for water- and environmental-resources management, <i>in</i> Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges, Williamsburg, VA, 19 July 2005 through 22 July 2005, p. 435-436.","startPage":"435","endPage":"436","numberOfPages":"2","costCenters":[],"links":[{"id":238378,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba7fae4b08c986b32191d","contributors":{"editors":[{"text":"Moglen G.E.","contributorId":128404,"corporation":true,"usgs":false,"organization":"Moglen G.E.","id":536617,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Leavesley, G.H.","contributorId":93895,"corporation":false,"usgs":true,"family":"Leavesley","given":"G.H.","email":"","affiliations":[],"preferred":false,"id":414147,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Markstrom, S.L.","contributorId":76807,"corporation":false,"usgs":true,"family":"Markstrom","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":414145,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Viger, Roland J. 0000-0003-2520-714X","orcid":"https://orcid.org/0000-0003-2520-714X","contributorId":80711,"corporation":false,"usgs":true,"family":"Viger","given":"Roland J.","affiliations":[],"preferred":false,"id":414146,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hay, L.E.","contributorId":54253,"corporation":false,"usgs":true,"family":"Hay","given":"L.E.","email":"","affiliations":[],"preferred":false,"id":414144,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The dam is located near Purvis, Mississippi, on Bay Creek, which flows into Lower Little Creek about 1.9 miles downstream from the dam. Lower Little Creek flows into Pearl River about 16.9 miles downstream from the dam. Knowledge of the hydrology and hydraulics of floods caused by dam breaks is essential to the design of dams. A better understanding of the risks associated with possible dam failures may help limit the loss of life and property that often occurs downstream of a dam failure. The USGS recovered flood marks at the one crossing of Bay Creek and eight crossings of Lower Little Creek. Additional flood marks were also flagged at three other bridges crossing tributaries where backwater occurred. Flood marks were recovered throughout the stream reach of about 3/4 to 15 miles downstream of the dam. Flood marks that were flagged will be surveyed so that a flood profile can be documented downstream of the Big Bay Lake dam failure. Peak discharges are also to be estimated where possible. News reports stated that the peak discharge at the dam was about 67,000 cubic feet per second. Preliminary data suggest the peak discharge from the dam failure attenuated to about 13,000 cubic feet per second at Lower Little Creek at State Highway 43, about 15 miles downstream of the dam.","largerWorkTitle":"Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceTitle":"2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceDate":"19 July 2005 through 22 July 2005","conferenceLocation":"Williamsburg, VA","language":"English","isbn":"0784407630","usgsCitation":"Van Wilson, K., 2005, Data collection and documentation of flooding downstream of a dam failure in Mississippi, <i>in</i> Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges, Williamsburg, VA, 19 July 2005 through 22 July 2005.","startPage":"1277","costCenters":[],"links":[{"id":238092,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fd6ee4b0c8380cd4e81f","contributors":{"editors":[{"text":"Moglen G.E.","contributorId":128404,"corporation":true,"usgs":false,"organization":"Moglen G.E.","id":536622,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Van Wilson, K.
