The filter accommodates three dynamic modes of ice effects: sudden formation/ablation, stable ice conditions, and eventual elimination. The utility of the filter was evaluated by applying it to historical data from two long-term streamflow-gauging stations, St. John River at Dickey, Maine and Platte River at North Bend, Nebr. Results indicate that the filter was stable and that parameters converged for both stations, producing streamflow estimates that are highly correlated with published values. For the Maine station, logarithms of estimated streamflows are within 8% of the logarithms of published values 87.2% of the time during periods of ice effects and within 15% 96.6% of the time. Similarly, for the Nebraska station, logarithms of estimated streamflows are within 8% of the logarithms of published values 90.7% of the time and within 15% 97.7% of the time. In addition, the correlation between temporal updates and published streamflows on days of direct measurements at the Maine station was 0.777 and 0.998 for ice-affected and open-water periods, respectively; for the Nebraska station, corresponding correlations were 0.864 and 0.997.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrologic Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1061/(ASCE)1084-0699(1998)3:3(174)","issn":"10840699","usgsCitation":"Holtschlag, D., and Grewal, M., 1998, Estimating ice-affected streamflow by extended Kalman filtering: Journal of Hydrologic Engineering, v. 3, no. 3, p. 174-181, https://doi.org/10.1061/(ASCE)1084-0699(1998)3:3(174).","startPage":"174","endPage":"181","numberOfPages":"8","costCenters":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"links":[{"id":230197,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0b23e4b0c8380cd525ba","contributors":{"authors":[{"text":"Holtschlag, D.

Studies of groups of adjacent wetlands in different parts of the glaciated North American prairie have enabled some connections to be made between hydrologic processes, biological communities, and use of these wetlands by wetland-dependent wildlife. Understanding controls on variability in water levels, water volume, and salinity in these wetlands sets the stage for understanding controls on biological communities utilizing these wetlands. The role that natural variability in water and salinity plays in making these wetlands an important resource for waterfowl will provide an important context for those who are responsible for artificially altering the variability of water and salinity in prairie wetlands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Great Plains Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"10525165","usgsCitation":"LaBaugh, J.W., Winter, T.C., and Rosenberry, D., 1998, Hydrologic functions of prairie wetlands: Great Plains Research, v. 8, no. 1, p. 17-37.","startPage":"17","endPage":"37","numberOfPages":"21","costCenters":[],"links":[{"id":229920,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268117,"type":{"id":11,"text":"Document"},"url":"https://digitalcommons.unl.edu/greatplainsresearch/361/"}],"volume":"8","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3633e4b0c8380cd604fa","contributors":{"authors":[{"text":"LaBaugh, J.

This system is needed in order to more effectively manage the Elmhurst Quarry Flood Control Facility, an off-line stormwater diversion reservoir located along Salt Creek. Near real time simulation capabilities will enable the testing and evaluation of potential rainfall, diversion, and return-flow scenarios on water-surface elevations along Salt Creek before implementing diversions or return-flows. The climatological inputs for the continuous-simulation rainfall-runoff model, Hydrologic Simulation Program - FORTRAN (HSPF) are obtained by Internet access and from a network of radio-telemetered precipitation gages reporting to a base-station computer. The unit area runoff time series generated from HSPF are the input for the dynamic-wave routing model. Full Equations (FEQ). The Generation and Analysis of Model Simulation Scenarios (GENSCN) interface is used as a pre- and post-processor for managing input data and displaying and managing simulation results. The GENSCN interface includes a variety of graphical and analytical tools for evaluation and quick visualization of the results of operational scenario simulations and thereby makes it possible to obtain the full benefit of the fully distributed dynamic routing results.","largerWorkTitle":"Proceedings of the Annual Water Resources Planning and Management Conference","conferenceTitle":"Proceedings of the 1998 25th Annual Conference on Water Resources Planning and Management","conferenceDate":"7 June 1998 through 10 June 1998","conferenceLocation":"Chicago, IL, USA","language":"English","publisher":"ASCE","publisherLocation":"Reston, VA, United States","usgsCitation":"Ishii, A.L., Charlton, T., Ortel, T., and Vonnahme, C., 1998, Operational modeling system with dynamic-wave routing, <i>in</i> Proceedings of the Annual Water Resources Planning and Management Conference, Chicago, IL, USA, 7 June 1998 through 10 June 1998, p. 147-152.","startPage":"147","endPage":"152","numberOfPages":"6","costCenters":[],"links":[{"id":229752,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6e92e4b0c8380cd756e4","contributors":{"editors":[{"text":"Loucks E","contributorId":128438,"corporation":true,"usgs":false,"organization":"Loucks E","id":536472,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Ishii, A.

A challenge particular to remotely sensed cover maps generated from these efforts is how best to assess the accuracy of the cover maps, especially when they can exceed 1000 s/km2 in size. Here we develop and describe a methodological approach for assessing the accuracy of large-area cover maps, using as a test case the 21.9 million ha cover map developed for Utah Gap Analysis. As part of our design process, we first reviewed the effect of intracluster correlation and a simple cost function on the relative efficiency of cluster sample designs to simple random designs. Our design ultimately combined clustered and subsampled field data stratified by ecological modeling unit and accessibility (hereafter a mixed design). We next outline estimation formulas for simple map accuracy measures under our mixed design and report results for eight major cover types and the three ecoregions mapped as part of the Utah Gap Analysis. Overall accuracy of the map was 83.2% (SE=1.4). Within ecoregions, accuracy ranged from 78.9% to 85.0%. Accuracy by cover type varied, ranging from a low of 50.4% for barren to a high of 90.6% for man modified. In addition, we examined gains in efficiency of our mixed design compared with a simple random sample approach. In regard to precision, our mixed design was more precise than a simple random design, given fixed sample costs. We close with a discussion of the logistical constraints facing attempts to assess the accuracy of large-area, remotely sensed cover maps.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Remote Sensing of Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier Science Inc","publisherLocation":"New York, NY, United States","doi":"10.1016/S0034-4257(96)00246-5","issn":"00344257","usgsCitation":"Edwards, T., Moisen, G.G., and Cutler, D., 1998, Assessing map accuracy in a remotely sensed, ecoregion-scale cover map: Remote Sensing of Environment, v. 63, no. 1, p. 73-83, https://doi.org/10.1016/S0034-4257(96)00246-5.","startPage":"73","endPage":"83","numberOfPages":"11","costCenters":[],"links":[{"id":206416,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0034-4257(96)00246-5"},{"id":229673,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"63","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eddae4b0c8380cd49a5d","contributors":{"authors":[{"text":"Edwards, T.C.

Measurements in highly permeable wells penetrating the main geothermal reservoir indicate that the local orientation of the least horizontal principal stress, Shmin, is nearly optimal for normal faulting on the Stillwater fault. Hydraulic fracturing tests from these wells further show that the magnitude of Shmin is low enough to lead to frictional failure on the Stillwater and nearby subparallel faults, suggesting that fault slip is responsible for the high reservoir productivity. Similar measurements were conducted in two wells penetrating a relatively impermeable segment of the Stillwater fault zone, located approx. 8 and 20 km southwest of the geothermal reservoir (wells 66-21 and 45-14, respectively). The orientation of Shmin in well 66-21 is near optimal for normal faulting on the nearby Stillwater fault, but the magnitude of Shmin is too high to result in incipient frictional failure. In contrast, although the magnitude of Shmin in well 45-14 is low enough to lead to normal faulting on optimally oriented faults, the orientation of the Stillwater fault near this well is rotated by approx. 40?? from the optimal orientation for normal faulting. This misorientation, coupled with an apparent increase in the magnitude of the greatest horizontal principal stress in going from the producing to nonproducing wells, acts to inhibit frictional failure on the Stillwater fault zone in proximity to well 45-14. Taken together, data from the nonproducing and producing wells thus suggest that a necessary condition for high reservoir permeability is that the Stillwater fault zone be critically stressed for frictional failure in the current stress field.","largerWorkTitle":"Proceedings of the SPE/ISRM Rock Mechanics in Petroleum Engineering Conference","conferenceTitle":"Proceedings of the 1998 SPR/ISRM Rock Mechanics In Petroleum Engineering, EUROCK.

To evaluate the model, we simulated published field studies and found that model predictions of insecticide decay and ChE inhibition reasonably approximated most observed results. Sensitivity analysis suggested that foraging location usually influenced ChE inhibition more than diet preferences or daily intake rate. Although organophosphorus insecticides usually caused greater inhibition than carbamate insecticides, insecticide toxicity appeared only moderately important. When we simulated impact of heavy insecticide applications during breeding seasons of 15 wild bird species, mean maximum ChE inhibition in most species exceeded 20% at some point. At this level of inhibition, birds may experience nausea and/or may exhibit minor behavioral changes. Simulated risk peaked in April–May and August–September and was lowest in July. ChE inhibition increased with proportion of vegetation in the diet. This model, and ones like it, may help predict insecticide exposure of and sublethal ChE inhibition in grassland animals, thereby reducing dependence of ecological risk assessments on field studies alone.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0304-3800(97)00174-9","issn":"03043800","usgsCitation":"Corson, M., Mora, M., and Grant, W., 1998, Simulating cholinesterase inhibition in birds caused by dietary insecticide exposure: Ecological Modelling, v. 105, no. 2-3, p. 299-323, https://doi.org/10.1016/S0304-3800(97)00174-9.","productDescription":"25 p.","startPage":"299","endPage":"323","numberOfPages":"25","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":229711,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206426,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0304-3800(97)00174-9"}],"volume":"105","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8fcde4b08c986b319148","contributors":{"authors":[{"text":"Corson, M.S.","contributorId":12999,"corporation":false,"usgs":true,"family":"Corson","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":389549,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mora, M.A.","contributorId":71923,"corporation":false,"usgs":true,"family":"Mora","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":389550,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Grant, W.E.","contributorId":78903,"corporation":false,"usgs":true,"family":"Grant","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":389551,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Peak water-column DGM concentrations were observed on or about noon, with a 3 to 7 fold increase over night-time concentrations. Production of DGM appears to cease during dark periods, with nearly constant water column concentrations that were at or near saturation with respect to the overlying air. A simple mass balance shows that the flux of Hg to the atmosphere from diel DGM production and evasion represents about 10% of the annual input from atmospheric deposition. Production of DGM is likely the result of an indirect photolysis reaction that involves the production of reductive species and/or reduction by electron transfer. Diel variability in Hg(T) and Hg(R) appears to be controlled by two factors: inputs from rainfall and photolytic sorption/desorption processes. A possible mechanism involves photolysis of chromophores on the surface of a solid substrate (e.g., the periphyton mat) giving rise to destabilization of sorbed mercury and net desorption during daylight. At night, the sorption reactions predominate and the water-column Hg(T) decreases. Methylmercury (MeHg) also showed diel trends in concentration but were not clearly linked to the solar cycle or rainfall at the study site.","language":"English","publisher":"Springer","doi":"10.1023/A:1005938607225","issn":"01682563","usgsCitation":"Krabbenhoft, D., Hurley, J., Olson, M., and Cleckner, L., 1998, Diel variability of mercury phase and species distributions in the Florida Everglades: Biogeochemistry, v. 40, no. 2-3, p. 311-325, https://doi.org/10.1023/A:1005938607225.","productDescription":"15 p.","startPage":"311","endPage":"325","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":229789,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"40","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00c4e4b0c8380cd4f8ea","contributors":{"authors":[{"text":"Krabbenhoft, D.

The late Tertiary arboreal pollen (AP) assemblages are dominated by oak, hickory, pine, birch and alder with minor amounts of mid- and southern coastal tree taxa, as well as minor spruce and hemlock and a trace of fir. Nonarboreal pollen (NAP) include grass, sedge, composite and aquatic taxa. Exotic pollen in these assemblages represent plants now foreign to this region. They may be placed in three categories. First, there are extinct forms, such as Labrapollis, Plicatopollis, and Multiporopollenites, that can be traced from the Cretaceous or Early Tertiary into the Late Tertiary. The second group includes forms, such as Podocarpus, Engelhardtia, Pterocarya, Ephedra, Eucommia, Ulmus-Zelkova, Glyptostrobus, Palmae, and Cyathea, that are not found in this region today and not found in early Pleistocene sediments in the eastern United States. Many of these taxa are subtropical or greatly restricted in geographic range. A third group of exotics, mainly Cyrilla, Planera, Gordonia, Jussiaea, and Sapotacaea, including Minusops, are generally found south of the study area or have their northern limit here at this time. The lack of the extinct or distant exotics in early to mid-Pleistocene sediments in the mid-Atlantic coastal plain and the last appearance of Pterocarya, as the last exotic taxon in the early Pleistocene of western Europe, support the stratigraphic assignment of the Pliocene units. The number of exotic taxa diminish markedly between the Miocene pollen assemblages and those of the Late Pliocene. Climatic fluctuations characterize the Late Tertiary environments. The Miocene, for example, incorporates a warming trend between the upper, middle Miocene and the Manokin beds and the late Miocene of the Pokomoke beds. The late Miocene was probably somewhat warner than the present climate in the Delmarva region. This trend is based on the presence of colder climate indicators, mainly spruce and hemlock, in the Manokin pollen record. The two distinct pollen assemblages constitute two pollen zones. Similarly, the Pliocene pollen record also shows a warming trend. The pollen zone of the Yorktown Formation of the early Pliocene age contains the colder climate indicators spruce and hemlock. The Beaverdam and Walston formation of late Pliocene age contain pollen assemblages that reflect climatic conditions warmer than the present time.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Northeastern Geology and Environmental Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"01941453","usgsCitation":"Sirkin, L., and Owens, J.P., 1998, Palynology of latest Neogene (Middle Miocene to late Pliocene) strata in the Delmarva Peninsula of Maryland and Virginia: Northeastern Geology and Environmental Sciences, v. 20, no. 2, p. 117-132.","startPage":"117","endPage":"132","numberOfPages":"16","costCenters":[],"links":[{"id":230267,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a74a1e4b0c8380cd77739","contributors":{"authors":[{"text":"Sirkin, L.","contributorId":63954,"corporation":false,"usgs":true,"family":"Sirkin","given":"L.","email":"","affiliations":[],"preferred":false,"id":389543,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Owens, J.

CDACs were prepared in bench-scale and pilot-scale fluidized-bed reactors with a three-step process, including coal preoxidation, carbonization, and then steam activation. CDACs from high-organicsulfur Illinois coals had a greater equilibrium Hg0 adsorption capacity than activated carbons prepared from a low-organic-sulfur Illinois coal. When a low-organic-sulfur CDAC was impregnated with elemental sulfur at 600 ??C, its equilibrium Hg0 adsorption capacity was comparable to the adsorption capacity of the activated carbon prepared from the high-organicsulfur coal. X-ray diffraction and sulfur K-edge X-ray absorption near-edge structure examinations showed that the sulfur in the CDACs was mainly in organic forms. These results suggested that a portion of the inherent organic sulfur in the starting coal, which remained in the CDACs, played an important role in adsorption of Hg0. Besides organic sulfur, the BET surface area and micropore area of the CDACs also influenced Hg0 adsorption capacity. The HgCl2 adsorption capacity was not as dependent on the surface area and concentration of sulfur in the CDACs as was adsorption of Hg0. The properties and mercury adsorption capacities of the CDACs were compared with those obtained for commercial Darco FGD carbon.","language":"English","publisher":"American Chemical Society","doi":"10.1021/ef9801064","issn":"08870624","usgsCitation":"Hsi, H.-., Chen, S., Rostam-Abadi, M., Rood, M., Richardson, C.F., Carey, T., and Chang, R., 1998, Preparation and evaluation of coal-derived activated carbons for removal of mercury vapor from simulated coal combustion flue fases: Energy and Fuels, v. 12, no. 6, p. 1061-1070, https://doi.org/10.1021/ef9801064.","productDescription":"10 p.","startPage":"1061","endPage":"1070","numberOfPages":"10","costCenters":[],"links":[{"id":228021,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"6","noUsgsAuthors":false,"publicationDate":"1998-10-09","publicationStatus":"PW","scienceBaseUri":"505a8b19e4b0c8380cd7e177","contributors":{"authors":[{"text":"Hsi, H. -C.","contributorId":82079,"corporation":false,"usgs":true,"family":"Hsi","given":"H.","middleInitial":"-C.","affiliations":[],"preferred":false,"id":384011,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chen, S.","contributorId":7856,"corporation":false,"usgs":true,"family":"Chen","given":"S.","affiliations":[],"preferred":false,"id":384006,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rostam-Abadi, M.","contributorId":37061,"corporation":false,"usgs":true,"family":"Rostam-Abadi","given":"M.","affiliations":[],"preferred":false,"id":384010,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rood, M.J.","contributorId":15354,"corporation":false,"usgs":true,"family":"Rood","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":384007,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Richardson, C.

The late Glacial to early Holocene climate in the northern Great Plains was characterized by changes from cold and wet to cold and dry, and back to cold and wet conditions. These climatic changes were controlled by fluctuations in the positions of the Laurentide ice sheet and the extent of glacial Lake Agassiz. We speculate that the cold and dry phase may correspond to the Younger Dryas event. A salinity maximum was reached between 10.3 and 9.5 ka, after which Pickerel Lake shifted from a system controlled by atmospheric changes to a system controlled by groundwater seepage that might have been initiated by the final withdrawal of Glacial Lake Agassiz. A prairie lake was established at approximately 8.7 ka, and lasted until about 2.2 ka. During this mid-Holocene prairie period, drier conditions than today prevailed, interrupted by periods of increased moisture at about 8, 4, and 2.2 ka. Prairie conditions were more likely dry and cool rather than dry and warm. The last 2.2 ka are characterized by higher climatic variability with 400-yr aridity cycles including the Medieval Warm Period and the Little Ice Age. Although the signal of changing atmospheric circulation is overprinted by fluctuations in the positions of the ice sheet and glacial Lake Agassiz during the late Glacial-Holocene transition, a combination of strong zonal circulation and strong monsoons induced by the presence of the ice sheet and high insolation may have provided mechanisms for increased precipitation. Zonal flow introducing dry Pacific air became more important during the prairie period but seems to have been interrupted by short periods of stronger meridional circulation with intrusions of moist air from the Gulf of Mexico. More frequent switching between periods of zonal and meridional circulation seem to be responsible for increased climatic variability during the last 2.2 ka.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Paleolimnology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1007971226750","issn":"09212728","usgsCitation":"Schwalb, A., and Dean, W., 1998, Stable isotopes and sediments from Pickerel Lake, South Dakota, USA: A 12ky record of environmental changes: Journal of Paleolimnology, v. 20, no. 1, p. 15-30, https://doi.org/10.1023/A:1007971226750.","startPage":"15","endPage":"30","numberOfPages":"16","costCenters":[],"links":[{"id":206414,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1007971226750"},{"id":229670,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9682e4b08c986b31b55c","contributors":{"authors":[{"text":"Schwalb, A.","contributorId":31129,"corporation":false,"usgs":true,"family":"Schwalb","given":"A.","email":"","affiliations":[],"preferred":false,"id":389544,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dean, W.E.","contributorId":97099,"corporation":false,"usgs":true,"family":"Dean","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":389545,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The aim of this work is to develop a better understanding of lithospheric structure of the Pacific Northwest, in particular the Cascadia subduction zone of Southwest Canada and Northwest USA. The goal is to compare and contrast the lithospheric density structure along two profiles across the subduction zone and to interpet the differences in terms of active processes. The subduction of the Juan de Fuca plate beneath North America changes markedly along the length of the subduction zone, notably in the angle of subduction, distribution of earthquakes and volcanism, goelogic and seismic structure of the upper plate, and regional horizontal stress. To investigate these characteristics, we conducted detailed density modeling of the crust and mantle along two transects across the Cascadia subduction zone. One crosses Vancouver Island and the Canadian margin, the other crosses the margin of central Oregon.","largerWorkTitle":"","language":"English","publisher":"Elsevier","doi":"10.1016/S0079-1946(98)00028-7","issn":"00791946","usgsCitation":"Romanyuk, T., Blakely, R., and Mooney, W.D., 1998, The Cascadia Subduction Zone: Two contrasting models of lithospheric structure: Physics and Chemistry of the Earth, v. 23, no. 3, p. 297-301, https://doi.org/10.1016/S0079-1946(98)00028-7.","productDescription":"5 p.","startPage":"297","endPage":"301","numberOfPages":"5","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":230186,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States, Canada","state":"Oregon, Washington, British Columbia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -125.20019531249999,\n              42.5530802889558\n            ],\n            [\n              -117.90527343750001,\n              42.5530802889558\n            ],\n            [\n              -117.90527343750001,\n              51.28940590271679\n            ],\n            [\n              -125.20019531249999,\n              51.28940590271679\n            ],\n            [\n              -125.20019531249999,\n              42.5530802889558\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"23","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba6bee4b08c986b32126b","contributors":{"authors":[{"text":"Romanyuk, T.V.","contributorId":91270,"corporation":false,"usgs":true,"family":"Romanyuk","given":"T.V.","email":"","affiliations":[],"preferred":false,"id":389530,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blakely, R.","contributorId":65569,"corporation":false,"usgs":true,"family":"Blakely","given":"R.","affiliations":[],"preferred":false,"id":389528,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mooney, Walter D. 0000-0002-5310-3631 mooney@usgs.gov","orcid":"https://orcid.org/0000-0002-5310-3631","contributorId":3194,"corporation":false,"usgs":true,"family":"Mooney","given":"Walter","email":"mooney@usgs.gov","middleInitial":"D.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":389529,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This experiment was conducted in two Louisiana coastal marshes to examine the effects of nutrient enrichment and sediment addition on herbaceous plant communities with and without vertebrate herbivory. After three growing seasons, fertilization increased community biomass in all plots, but decreased species density (the number of species per unit area) only in plots protected from herbivory. Herbivory alone did not alter species density at either site. At the brackish marsh, herbivory caused a shift in dominance in the fertilized plots from a species that is considered the competitive dominant, but is selectively eaten, to another less palatable species. At the fresh marsh, increased dead biomass in the absence of herbivory and in the fertilized plots probably contributed to the decrease in species density, perhaps by limiting germination of annuals. Our results support those of other fertilization studies in which plant species density decreases with increased biomass, but only in those plots protected from herbivory.","language":"English","publisher":"Ecological Society of America","doi":"10.1890/0012-9658(1998)079[1586:HEOPSD]2.0.CO;2","issn":"00129658","usgsCitation":"Gough, L., and Grace, J., 1998, Herbivore effects on plant species density at varying productivity levels: Ecology, v. 79, no. 5, p. 1586-1594, https://doi.org/10.1890/0012-9658(1998)079[1586:HEOPSD]2.0.CO;2.","productDescription":"9 p.","startPage":"1586","endPage":"1594","numberOfPages":"9","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":229716,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Louisiana","otherGeospatial":"Pearl River Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.77752685546875,\n              30.135626231134587\n            ],\n            [\n              -89.53033447265625,\n              30.135626231134587\n            ],\n            [\n              -89.53033447265625,\n              30.44748978060767\n            ],\n            [\n              -89.77752685546875,\n              30.44748978060767\n            ],\n            [\n              -89.77752685546875,\n              30.135626231134587\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"79","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3073e4b0c8380cd5d661","contributors":{"authors":[{"text":"Gough, L.","contributorId":53971,"corporation":false,"usgs":true,"family":"Gough","given":"L.","affiliations":[],"preferred":false,"id":389703,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grace, J.B. 0000-0001-6374-4726","orcid":"https://orcid.org/0000-0001-6374-4726","contributorId":38938,"corporation":false,"usgs":true,"family":"Grace","given":"J.B.","affiliations":[],"preferred":false,"id":389702,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
