Demographic data from both breeding and non-breeding periods are needed to manage populations of migratory birds, many of which are declining in abundance and are of conservation concern. Although habitat associations, and to a lesser extent, reproductive biology, are known for many migratory species, few studies have measured survival rates of these birds at different parts of their annual cycle. 2. Cormack-Jolly-Seber models and Akaike's information criterion model selection were used to investigate seasonal variation in survival of a Nearctic - Neotropical migrant songbird, the black-throated blue warbler, Dendroica caerulescens. Seasonal and annual survival were estimated from resightings of colour-ringed individuals on breeding grounds in New Hampshire, USA from 1986 to 2000 and on winter quarters in Jamaica, West Indies from 1986 to 1999. Warblers were studied each year during the May-August breeding period in New Hampshire and during the October-March overwinter period in Jamaica. 3. In New Hampshire, males had higher annual survival (0.51 ?? 0.03) and recapture probabilities (0.93 ?? 0.03) than did females (survival: 0.40 ?? 0.04; recapture: 0.87 ?? 0.06). In Jamaica, annual survival (0.43 ?? 0.03) and recapture (0.95 ?? 0.04) probabilities did not differ between sexes. Annual survival and recapture probabilities of young birds (i.e. yearlings in New Hampshire and hatch-year birds in Jamaica) did not differ from adults, indicating that from the time hatch-year individuals acquire territories on winter quarters in mid-October, they survive as well as adults within the same habitat. 4. Monthly survival probabilities during the summer (May-August) and winter (October-March) stationary periods were high: 1.0 for males in New Hampshire, and 0.99 ?? 0.01 for males in Jamaica and for females in both locations. 5. These annual and seasonal survival estimates were used to calculate warbler survival for the migratory periods. Monthly survival probability during migration ranged from 0.77 to 0.81 ?? 0.02. Thus, apparent mortality rates were at least 15 times higher during migration compared to that in the stationary periods, and more than 85% of apparent annual mortality of D. caerulescens occurred during migration. 6. Additional data from multiple species, especially measures of habitat-specific demography and dispersal, will improve our understanding of the relative impacts of the breeding, migratory, and winter periods on population dynamics of migratory birds and thus enhance future conservation efforts.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Animal Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1046/j.1365-2656.2002.00599.x","issn":"00218790","usgsCitation":"Scott, S.T., and Holmes, R.T., 2002, Variation in survivorship of a migratory songbird throughout its annual cycle: Journal of Animal Ecology, v. 71, no. 2, p. 296-308, https://doi.org/10.1046/j.1365-2656.2002.00599.x.","startPage":"296","endPage":"308","numberOfPages":"13","costCenters":[],"links":[{"id":207896,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1365-2656.2002.00599.x"},{"id":233178,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"71","issue":"2","noUsgsAuthors":false,"publicationDate":"2002-04-19","publicationStatus":"PW","scienceBaseUri":"505bc166e4b08c986b32a55d","contributors":{"authors":[{"text":"Scott, Sillett T.","contributorId":30003,"corporation":false,"usgs":true,"family":"Scott","given":"Sillett","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":402773,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Holmes, Richard T.","contributorId":45269,"corporation":false,"usgs":true,"family":"Holmes","given":"Richard","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":402774,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The research was done at a topographically high (upland) site and a depressional (lowland) site within a corn field. Agricultural chemicals that move readily with water were most directly affected by focused recharge to the lowland site. Surface runoff of water to the lowland site was the primary cause for the generally greater flux of chloride, nitrate nitrogen, and sulfate compared with the upland site. Based on data from the unsaturated zone, for example, the average annual fluxes of these chemicals in 1992&ndash;1993 were 5.1, 3.4, and 1.7 times greater, respectively, at the lowland site. Study results indicate that consideration should be given to modifying site-specific management farming technology to account for varying recharge rates in different topographic settings. By reducing chemical application rates in topographic depressions, where focused recharge of chemicals occurs because of surface runoff, farmers could improve ground-water quality as well as reduce expenditures for agricultural chemicals.</span></p>","language":"English","publisher":"International Association of Hydrogeologists","doi":"10.1007/s10040-002-0208-6","issn":"14312174","usgsCitation":"Delin, G., and Landon, M., 2002, Effects of topography on the transport of agricultural chemicals to groundwater in a sand-plain setting: Hydrogeology Journal, v. 10, no. 4, p. 443-454, https://doi.org/10.1007/s10040-002-0208-6.","productDescription":"12 p.","startPage":"443","endPage":"454","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":392,"text":"Minnesota Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":233263,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207942,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10040-002-0208-6"}],"country":"United States","state":"Minnesota","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -93.5430908203125,\n              45.21687321093267\n            ],\n            [\n              -93.5430908203125,\n              45.49287107405929\n            ],\n            [\n              -93.07891845703125,\n              45.49287107405929\n            ],\n            [\n              -93.07891845703125,\n              45.21687321093267\n            ],\n            [\n              -93.5430908203125,\n              45.21687321093267\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"10","issue":"4","noUsgsAuthors":false,"publicationDate":"2002-05-22","publicationStatus":"PW","scienceBaseUri":"505a0810e4b0c8380cd51967","contributors":{"authors":[{"text":"Delin, G.

It also results in textures and mineralogies that are distinct from other forms of (mainly pedogenic) low temperature alteration. Specifically, the process of palagonitization (1) initially results in the formation of 'palaginitized glass', a quasi- or nano-crystalline, rind-like material that contains smectite, as well as lesser amounts of other clays (e.g. serpentine), and (2) eventually results in consolidation of tephra, mediated through the accretion of palagonitized glass and later- formed authigenic cements. Conversely, pedogenic weathering of glassy basaltic tephra is characterized by disaggregation of tephra, and formation of a wide range of pedogenic products, including layer silicates (although not primarily smectite), short-range-order aluminosilicates and oxyhydroxides, whose composition reflects the intensity of the weathering environment. These mineralogical and textural properties can be readily recognized through a variety of techniques including electron microscopy/microprobe analysis, reflectance spectroscopy, X-ray diffraction and soil chemistry. Analyses of samples collected from the summit regions of Kilauea and Mauna Kea volcanoes on the island of Hawaii are presented here in order to illustrate differences between palagonitization and pedogenic weathering of glassy basaltic tephra. In the young Hawaiian tephras studied, palagonitization has occurred in response to hydrothermal activity shortly after deposition. Although some, non-hydrothermally affected tephras may eventually become palagonitized, those that have been strongly desilicated by intense pedogenic weathering will probably never become palagonitized.</p>","language":"English","publisher":"Geological Society of London","doi":"10.1144/GSL.SP.2002.202.01.20","issn":"03058719","usgsCitation":"Schiffmant, P., Southard, R., Eberl, D.D., and Bishop, J., 2002, Distinguishing palagonitized from pedogenically-altered basaltic Hawaiian tephra: Mineralogical and geochemical criteria: Geological Society Special Publication, no. 202, p. 393-405, https://doi.org/10.1144/GSL.SP.2002.202.01.20.","productDescription":"13 p.","startPage":"393","endPage":"405","numberOfPages":"13","costCenters":[],"links":[{"id":231838,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"202","noUsgsAuthors":false,"publicationDate":"2003-02-03","publicationStatus":"PW","scienceBaseUri":"505a0251e4b0c8380cd4ffd4","contributors":{"authors":[{"text":"Schiffmant, Peter","contributorId":51016,"corporation":false,"usgs":true,"family":"Schiffmant","given":"Peter","affiliations":[],"preferred":false,"id":400263,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Southard, R.J.","contributorId":83703,"corporation":false,"usgs":true,"family":"Southard","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":400266,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Eberl, D.

Analyses of campaign GPS, leveling data, and interferometric synthetic aperture radar (InSAR) data from the ERS-2 satellite also reveal significant deformation from the swarm. We interpret the swarm as resulting from a dike intrusion and model the deformation field using a constant pressure dike source. Nonlinear inversion was used to find the model that best fits the data. The optimal dike is located beneath and slightly to the west of Mauna Ulu, dips steeply toward the south, and strikes nearly east-west.

The fracture geometry of the gently east plunging fold is very regular and consists predominately of south dipping to subhorizontal to north dipping bedding-plane parting and east striking, steeply dipping axial-plane spaced cleavage. In the area of the piezometer arrays, which trend north-south on the north limb of the fold, north dipping bedding-plane parting is a more dominant fracture set than is steeply south dipping axial-plane cleavage. The dating of ground water from the piezometer arrays reveals that ground water traveling along paths parallel to the dip direction of bedding-plane parting has younger 3H/3He and CFC model ages, or a greater component of young water, than does ground water traveling along paths opposite to the dip direction. In predominantly unmixed samples there is a strong positive correlation between age of the young fraction of water and dissolved sodium concentration. The travel times inferred from the model ages are significantly longer than those previously calculated by a ground water flow model, which assumed isotropically fractured layers parallel to topography. A revised model factors in the directional anisotropy to produce longer travel times. Ground water travel times in the watershed therefore appear to be more influenced by anisotropic fracture geometry than previously realized. This could have significant implications for ground water models in other areas underlain by similarly tilted or folded sedimentary rock, such as elsewhere in the Valley and Ridge or the early Mesozoic basins.","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.2002.tb02652.x","issn":"0017467X","usgsCitation":"Burton, W., Plummer, N., Busenberg, E., Lindsey, B., and Gburek, W., 2002, Influence of fracture anisotropy on ground water ages and chemistry, Valley and Ridge province, Pennsylvania: Ground Water, v. 40, no. 3, p. 242-257, https://doi.org/10.1111/j.1745-6584.2002.tb02652.x.","productDescription":"16 p.","startPage":"242","endPage":"257","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":233096,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Pennsylvania","otherGeospatial":"Valley and Ridge Province","volume":"40","issue":"3","noUsgsAuthors":false,"publicationDate":"2005-12-13","publicationStatus":"PW","scienceBaseUri":"505a3b3ae4b0c8380cd6233c","contributors":{"authors":[{"text":"Burton, W.C.","contributorId":41439,"corporation":false,"usgs":true,"family":"Burton","given":"W.C.","email":"","affiliations":[],"preferred":false,"id":402186,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Plummer, Niel 0000-0002-4020-1013 nplummer@usgs.gov","orcid":"https://orcid.org/0000-0002-4020-1013","contributorId":190100,"corporation":false,"usgs":true,"family":"Plummer","given":"Niel","email":"nplummer@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":402189,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Busenberg, E.","contributorId":56796,"corporation":false,"usgs":true,"family":"Busenberg","given":"E.","affiliations":[],"preferred":false,"id":402187,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lindsey, B.D.","contributorId":89696,"corporation":false,"usgs":true,"family":"Lindsey","given":"B.D.","email":"","affiliations":[],"preferred":false,"id":402190,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Gburek, W.J.","contributorId":76098,"corporation":false,"usgs":true,"family":"Gburek","given":"W.J.","affiliations":[],"preferred":false,"id":402188,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The aggressive nature of the species has led to concerns over its potential adverse impacts to native plants, fish, and invertebrates. We conducted a study to determine the efficacy of glyphosate [isopropylamine salt of N-(phosphono-methyl)glycine] and several surfactants for control of giant salvinia. Studies were conducted over a 42-day period using static renewals (twice weekly) with 4% Hoagland's medium (10 mg/L N equivalent) in replicated 2-L containers. Five concentrations of glyphosate (0, 0.45, 0.91, 1.82, and 3.60% v:v) and five surfactants (0.25% concentration, v:v; Optima???, Kinetic???, Mon 0818???, Cygnet Plus???, and LI-700???) were applied with a pressurized sprayer as a single surface application in a fully nested experimental design. Untreated giant salvinia grew rapidly and exhibited an increase of 800% wet weight biomass over the 42-day test duration. Glyphosate, with and without surfactants, exhibited efficacy at concentrations as low as 0.45% of the commercial formulation.

Innovative solutions in fieldcraft, devised for the 11 new GPS stations, provide high-quality observations with 1-year time histories on stable monuments at remote sites. We report on our results from processing the postseismic GPS data available from these sites, as well as 8 other SCIGN stations within 80 km of the event (a total of 19 sites). From these data, we analyze the temporal character and spatial pattern of the postseismic transients. Data from some sites display statistically significant time variation in their velocities. Although this is less certain, the spatial pattern of change in the postseismic velocity field also appears to have changed. The pattern now is similar to the pre-Landers (pre-1992) secular field, but laterally shifted and locally at twice the rate. We speculate that a 30 km ?? 50 km portion of crust (near Twentynine Palms), which was moving at nearly the North American plate rate (to within 3.5 mm/yr of that rate) prior to the 1992 Landers sequence, now is moving along with the crust to the west of it, as though it has been entrained in flow along with the Pacific Plate as a result of the Landers and Hector Mine earthquake sequence. The inboard axis of right-lateral shear deformation (at lower crustal to upper mantle depth) may have jumped 30 km farther into the continental crust at this fault junction that comprises the southern end of the eastern California shear zone.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120000912","issn":"00371106","usgsCitation":"Hudnutt, K., King, N., Galetzka, J., Stark, K., Behr, J., Aspiotes, A., van, W.S., Moffitt, R., Dockter, S., and Wyatt, F., 2002, Continuous GPS observations of postseismic deformation following the 16 October 1999 Hector Mine, California, earthquake (Mw 7.1): Bulletin of the Seismological Society of America, v. 92, no. 4, p. 1403-1422, https://doi.org/10.1785/0120000912.","startPage":"1403","endPage":"1422","numberOfPages":"20","costCenters":[],"links":[{"id":478721,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20140801-153058779","text":"External Repository"},{"id":207858,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120000912"},{"id":233105,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"92","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fa57e4b0c8380cd4da68","contributors":{"authors":[{"text":"Hudnutt, K.W.","contributorId":104674,"corporation":false,"usgs":true,"family":"Hudnutt","given":"K.W.","email":"","affiliations":[],"preferred":false,"id":402763,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"King, N.E.","contributorId":29950,"corporation":false,"usgs":true,"family":"King","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":402754,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Galetzka, J.E.","contributorId":95238,"corporation":false,"usgs":true,"family":"Galetzka","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":402761,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stark, K.F.","contributorId":61987,"corporation":false,"usgs":true,"family":"Stark","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":402757,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Behr, J.A.","contributorId":36318,"corporation":false,"usgs":true,"family":"Behr","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":402755,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Aspiotes, A.","contributorId":94466,"corporation":false,"usgs":true,"family":"Aspiotes","given":"A.","email":"","affiliations":[],"preferred":false,"id":402760,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"van, Wyk S.","contributorId":52757,"corporation":false,"usgs":true,"family":"van","given":"Wyk","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":402756,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Moffitt, R.","contributorId":73783,"corporation":false,"usgs":true,"family":"Moffitt","given":"R.","email":"","affiliations":[],"preferred":false,"id":402759,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Dockter, S.","contributorId":98504,"corporation":false,"usgs":true,"family":"Dockter","given":"S.","email":"","affiliations":[],"preferred":false,"id":402762,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Wyatt, F.","contributorId":68047,"corporation":false,"usgs":true,"family":"Wyatt","given":"F.","email":"","affiliations":[],"preferred":false,"id":402758,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Time-since-burn, the time lapse from the date of burn to the date of image collection, was related to variation in mean NDVI over time. Regression analysis showed that NDVI increased for about 300 to 400 days immediately after the burn, overshooting the typical mean NDVI of a nonburned marsh. For about another 500 to 600 days NDVI decreased until reaching a nearly constant NDVI of about 0.40. During the phase of increasing NDVI the ability to predict time-since-burn was within about ??60 days. Within the decreasing phase this dropped to about ??88 days. Examination of each burn site revealed some nonburn related influences on NDVI (e.g., seasonality). Normalization of burn NDVI by site-specific nonburn control NDVI eliminated most influences. However, differential responses at the site-specific level remained related to either storm impacts or secondary burning. At these sites, collateral data helped clarify the abnormal changes in NDVI. Accounting for these abnormalities, site-specific burn recovery trends could be broadly standardized into four general phases: Phase 1-preburn, Phase 2-initial recovery (increasing NDVI), Phase 3-late recovery (decreasing NDVI), and Phase 4-final coalescence (unchanging NDVI). Phase 2 tended to last about 300 to 500 days, Phase 3 an additional 500 to 600 days, and finally reaching Phase 4, 900 to 1,000 days after burn.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1014362616119","issn":"09234861","usgsCitation":"Ramsey, E., Sapkota, S., Barnes, F., and Nelson, G., 2002, Monitoring the recovery of Juncus roemerianus marsh burns with the normalized difference vegetation index and Landsat Thematic Mapper data: Wetlands Ecology and Management, v. 10, no. 1, p. 85-96, https://doi.org/10.1023/A:1014362616119.","startPage":"85","endPage":"96","numberOfPages":"12","costCenters":[],"links":[{"id":233068,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207831,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1014362616119"}],"volume":"10","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5df0e4b0c8380cd706cb","contributors":{"authors":[{"text":"Ramsey, Elijah W.

Welaka was selected as the reference site in this study because of its low urban and agricultural development, Palatka is in close proximity to a paper mill plant, the Green Cove site is influenced by marine shipping activities and Julington Creek site receives discharges of domestic wastewater and storm water runoff from recreational boating marinas. For this study, bass were sampled both prior to (September 1996) and during the spawning season (February 1997). In order to characterize chemical exposure, bass livers were analyzed for up to 90 trace organics and 11 trace metal contaminants. Reproductive parameters measured included gonadosomatic index (GSI), histological evaluation of gonads and plasma concentrations of vitellogenin (VTG), 17??-estradiol (E2) and 11-ketotestosterone (11-KT). In general, the sum of organic chemicals was highest in livers from Palatka bass and bass from Green Cove and Julington Creek had higher hepatic concentrations of low molecular polycyclic aromatic hydrocarbons and polychlorinated biphenyls when compared to fish from Welaka. Metals were more variable across sites, with highest mean concentrations found in bass from either Julington Creek (Ag, As, Cr, Cu, Zn) or Welaka (Cd, Hg, Pb, Se, Tn). Female bass from Palatka and Green Cove had lower concentrations of E2, VTG and lower GSI in relation to Welaka. Males from Palatka and Green Cove showed comparable declines in 11-KT in relation to males from Julington Creek and GSI were decreased only in Palatka males. These results indicate a geographical trend in reproductive effects, with changes being most pronounced at the site closest to the paper mill (Palatka) and decreasing as the St. Johns River flows downstream. Since reproductive alterations were most evident in bass sampled from the site closest to the paper mill discharge, it is possible that exposure to these effluents might explain at least some of the results reported here. However, the presence of reproductive alterations in fish sampled at a considerable distance from the mill discharge (Green Cove, 40 km) would suggest exposure to chemicals released from sources other than the paper mill plant. It is clear that additional studies are needed to evaluate the potential impact of these reproductive changes in populations of Florida largemouth bass inhabiting the St. Johns River. ?? 2002 Elsevier Science B.V.

The predicted change in Coulomb stress near the hypocenter of the Hector Mine earthquake increases from 0.02 to 0.05 MPa during the 7-yr interval separating the two events. This increase is primarily attributed to the recovery of decreased excess fluid pressure from the 1992 Landers coseismic (undrained) strain field.

The spatial statistics from the 1:2,500,000-scale United States geologic map of Nevada, the central United States, and the northeastern United States quantify the differences in complexity and variability between these three geologic terranes. Nevada is defined by a large number of patches of small size and low size variability, whereas the Central area has a small number of patches with smaller relative size variability. All three areas have similar map-unit shape complexity with Nevada having the lowest. Based on the density of edges, the areas can be ranked from highest to lowest, as Nevada, Central, and Northeast. The Shannon diversity index ranks the areas from highest to lowest, as Northeast, Nevada, and Central, but the Shannon evenness index ranks them from highest to lowest, as Northeast, Central, and Nevada. These rankings may reflect the influence of folding in the Northeast and Central areas as opposed to basin and range extension in Nevada. The core areas statistic ranks the areas for spatial accuracy from highest to lowest, as Central, Northeast, and Nevada, with Northeast and Nevada being similar. For a scale comparison, the FRAGSTATS statistics quantify the increased complexity and spatial accuracy that is inherent in going from small- to larger-scale maps. For example for 1:2,500,000-1:500,000-scale maps of Nevada, respectively, the area weighted fractal dimension increase from 1.1 to 1.18, and the total core areas index almost doubles from 39.09 to 63.38. In addition, the fractal dimensions discriminate gross lithology and tectonic terranes. ?? 2002 Elsevier Science Ltd.

However, several questions of practical significance remain unresolved.

A general dynamic interpretation is proposed that describes the relationship between water level response and transducer‐measured head. This theory is utilized to develop a procedure for transforming model‐generated water level responses to transducer readings. The magnitude of the difference between the actual water level position and the apparent position based on the transducer measurement is a function of the acceleration and velocity of the water column, test geometry, and depth of the transducer.

These partially cut stands were harvested 12-96 years ago, when 16-96% of the former stand basal area was removed. Partial cutting maintained stand structures similar to uncut old-growth stands, and the cutting had no significant effects on tree species composition. The establishment of new-tree cohorts was positively related to the proportion of basal-area cut. The current stand basal area, tree species composition, and stand growth were significantly related to trees left after harvest (p < 0.001). Trees that were 20-80 cm dbh at the time of cutting had the greatest tree-diameter and basal-area growth and contributed the most to stand growth. Diameter growth of Sitka spruce and western hemlock was similar, and the proportion of stand basal-area growth between species was consistent for different cutting intensities. Concerns about changing tree species composition, lack of spruce regeneration, and greatly reduced stand growth and vigor with partial cuts were largely unsubstantiated. Silvicultural systems based on partial cutting can provide rapidly growing trees for timber production while maintaining complex stand structures with mixtures of spruce and hemlock trees similar to oldgrowth stands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Forest Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0378-1127(00)00727-1","issn":"03781127","usgsCitation":"Deal, R., and Tappeiner, J., 2002, The effects of partial cutting on stand structure and growth of western hemlock-Sitka spruce stands in southeast Alaska: Forest Ecology and Management, v. 159, no. 3, p. 173-186, https://doi.org/10.1016/S0378-1127(00)00727-1.","startPage":"173","endPage":"186","numberOfPages":"14","costCenters":[],"links":[{"id":232960,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207765,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0378-1127(00)00727-1"}],"volume":"159","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bab92e4b08c986b322f24","contributors":{"authors":[{"text":"Deal, R.L.","contributorId":51501,"corporation":false,"usgs":true,"family":"Deal","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":402594,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tappeiner, J.

The SLMD (patent pending) consists of a 2.5-cm-wide by 15-cm-long strip of low-density polyethylene (LDPE) layflat tubing containing 1 mL of an equal mixture (v/v) of oleic acid (cis-9-octadecenoic acid) and EMO-8Q (7-[4-ethyl-1-methyloctyl]-8-quinolinol). The reagent mixture continuously diffuses to the exterior surface of the LDPE membrane, and provides for sequestration of several divalent metals for up to several weeks.

This suggests a causal role for the Landers earthquake in triggering the Hector Mine earthquake. Previous modeling of the static stress change associated with the Landers earthquake shows that the area of peak Hector Mine slip lies where the Coulomb failure stress promoting right-lateral strike-slip failure was high, but the nucleation point of the Hector Mine rupture was neutrally to weakly promoted, depending on the assumed coefficient of friction. Possible explanations that could account for the 7-year delay between the two ruptures include background tectonic stressing, dissipation of fluid pressure gradients, rate- and state-dependent friction effects, and post-Landers viscoelastic relaxation of the lower crust and upper mantle. By employing a viscoelastic model calibrated by geodetic data collected during the time period between the Landers and Hector Mine events, we calculate that postseismic relaxation produced a transient increase in Coulomb failure stress of about 0.7 bars on the impending Hector Mine rupture surface. The increase is greatest over the broad surface that includes the 1999 nucleation point and the site of peak slip further north. Since stress changes of magnitude greater than or equal to 0.1 bar are associated with documented causal fault interactions elsewhere, viscoelastic relaxation likely contributed to the triggering of the Hector Mine earthquake. This interpretation relies on the assumption that the faults occupying the central Mojave Desert (i.e., both the Landers and Hector Mine rupturing faults) were critically stressed just prior to the Landers earthquake.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120000918","usgsCitation":"Pollitz, F., and Sacks, I.S., 2002, Stress triggering of the 1999 Hector Mine earthquake by transient deformation following the 1992 Landers earthquake: Bulletin of the Seismological Society of America, v. 92, no. 4, p. 1487-1496, https://doi.org/10.1785/0120000918.","productDescription":"10 p.","startPage":"1487","endPage":"1496","numberOfPages":"10","costCenters":[],"links":[{"id":232890,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Hector Mine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -117,\n              35\n            ],\n            [\n              -117,\n              33.5\n            ],\n            [\n              -116,\n              33.5\n            ],\n            [\n              -116,\n              35\n            ],\n            [\n              -117,\n              35\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"92","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9b6be4b08c986b31ce8e","contributors":{"authors":[{"text":"Pollitz, F.

Concentrations of the hexacyanoferrate complex, iron, manganese, and ammonium were higher at night than during the day, whereas weak-acid-dissociable cyanide, silver, gold, copper, nitrite, and pH displayed the reverse behavior. The changes in cyanide speciation, iron, and trace metals can be explained by photodissociation of iron and cobalt cyanocomplexes as the solutions emerged from the heap into sunlight-exposed channels. At midday, environmentally significant concentrations of free cyanide were produced in a matter of minutes, causing trace copper, silver, and gold to be mobilized as cyanocomplexes from solids. Whether rapid photodissociation is a general phenomenon common to other sites will be important to determine in reaching a general understanding of the environmental risks posed by routine or accidental water discharges from precious metal mining facilities.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es011064s","issn":"0013936X","usgsCitation":"Johnson, C.A., Leinz, R.W., Grimes, D.J., and Rye, R.O., 2002, Photochemical changes in cyanide speciation in drainage from a precious metal ore heap: Environmental Science & Technology, v. 36, no. 5, p. 840-845, https://doi.org/10.1021/es011064s.","startPage":"840","endPage":"845","numberOfPages":"6","costCenters":[],"links":[{"id":207695,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es011064s"},{"id":232854,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"5","noUsgsAuthors":false,"publicationDate":"2002-01-24","publicationStatus":"PW","scienceBaseUri":"505a78c4e4b0c8380cd78795","contributors":{"authors":[{"text":"Johnson, C.

At starting pH values above 12, the disappearance of picrate begins immediately and is first order in OH-. At lower pH, there is an induction period preceding the disappearance, and over the pH range 6.7-11.9 there is no pH dependence in the developed reaction phase. Added borate and silicate salts promote the reaction, suggesting their acting as nucleophiles at hydrothermal conditions. Nitrite is an initial product, while acetate is a final product and reflective of a vigorous oxidative sequence consuming the intermediate products. A reaction sequence consistent with the results at the lower pH includes initiation of a chain process by displacement of nitrite by water, followed by nucleophilic displacement of nitrite by nitrite such that a nitro group is replaced by an O-N=O group. The ester then rapidly hydrolyzes, and the net reaction is the production of an additional nitrite with each cycle. A simple modeling of this system satisfactorily fits the experimental findings. ?? 2002 Elsevier Science B.V.
