The objective is to minimize the cost of water supply subject to: water demand constraints, hydraulic head constraints to control seawater intrusion, and water capacity constraints. The decision variables are montly water deliveries from surface water and groundwater. The state variables are hydraulic heads. The drought of 1947-51 is the city's worst drought on record, and simulated surface-water supplies for this period were used as a basis for testing optimal management of current water resources under drought conditions. The simulation-optimization model was applied using three reservoir operation rules. In addition, the model's sensitivity to demand, carry over [the storage of water in one year for use in the later year(s)], head constraints, and capacity constraints was tested.","language":"English","publisher":"ASCE","doi":"10.1061/(ASCE)0733-9496(1998)124:5(252)","issn":"07339496","usgsCitation":"Nishikawa, T., 1998, Water-resources optimization model for Santa Barbara, California: Journal of Water Resources Planning and Management, v. 124, no. 5, p. 252-263, https://doi.org/10.1061/(ASCE)0733-9496(1998)124:5(252).","productDescription":"12 p.","startPage":"252","endPage":"263","numberOfPages":"12","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":229678,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206418,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)0733-9496(1998)124:5(252)"}],"volume":"124","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bcedfe4b08c986b32e5e9","contributors":{"authors":[{"text":"Nishikawa, Tracy 0000-0002-7348-3838 tnish@usgs.gov","orcid":"https://orcid.org/0000-0002-7348-3838","contributorId":1515,"corporation":false,"usgs":true,"family":"Nishikawa","given":"Tracy","email":"tnish@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":387671,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The present study uses the much neglected trace-fossil fauna to describe the diverse paleoenvironments represented in the Deadwood-Aladdin deposystems, and to better understand the environmental conditions that controlled benthic life in the Early Paleozoic. The Deadwood-Aladdin ichnotaxa can be separated into three distinct assemblages based on the changing sedimentologic and hydrodynamic conditions that existed across the Cambro-Ordovician shelf. Trace-fossil assemblages and corresponding lithofacies characteristics indicate that the Deadwood-Aladdin deposystems formed within an intertidal-flat and subtidal-shelf environment. Based on the distribution and numbers of preserved ichnotaxa, the intertidal flat can be subdivided further into an ecologically stressful inner sand-flat environment, and a more normal marine outer sand-flat environment, both of which belong to a mixed, Skolithos-Cruziana softground ichnofacies. The inner sand flat is characterized by low diversity, low numbers, and a general lack of complexly constructed ichnotaxa. Trace fossils common to both assemblages tend to be smaller in the inner flat compared to the outer sand flat. Taphonomic effects, such as substrate type and sediment heterogeneity, also aid in differentiating between the inner and outer sand-flat assemblages. The subtidal shelf environment is categorized in the Cruziana Ichnofacies. Ichnological evidence of periodic tempestite deposition and hardground development within this subtidal regime is manifested by high diversity and low abundance of ichnogenera.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Annals of Carnegie Museum","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00974463","usgsCitation":"Stanley, T., and Feldmann, R., 1998, Significance of nearshore trace-fossil assemblages of the cambro-ordovician deadwood formation and Aladdin Sandstone, South Dakota: Annals of Carnegie Museum, v. 67, no. 1, p. 1-51.","startPage":"1","endPage":"51","numberOfPages":"51","costCenters":[],"links":[{"id":231312,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"67","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8f1be4b08c986b318d1e","contributors":{"authors":[{"text":"Stanley, T.M.","contributorId":70145,"corporation":false,"usgs":true,"family":"Stanley","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":387172,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Feldmann, R.M.","contributorId":19330,"corporation":false,"usgs":true,"family":"Feldmann","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":387171,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

(1996) show substantial changes in direction of slip with time at specific points on the Nojima and Rokko fault systems, as do striations we observed on exposures of the Nojima fault surface on Awaji Island. Spudich (1992) showed that the initial stress, that is, the shear traction on the fault before the earthquake origin time, can be derived at points on the fault where the slip rake rotates with time if slip velocity and stress change are known at these points. From Yoshida's slip model, we calculated dynamic stress changes on the ruptured fault surfaces. To estimate errors, we compared the slip velocities and dynamic stress changes of several published models of the earthquake. The differences between these models had an exponential distribution, not gaussian. We developed a Bayesian method to estimate the probability density function (PDF) of initial stress from the striations and from Yoshida's slip model. Striations near Toshima and Hirabayashi give initial stresses of about 13 and 7 MPa, respectively. We obtained initial stresses of about 7 to 17 MPa at depths of 2 to 10 km on a subset of points on the Nojima and Rokko fault systems. Our initial stresses and coseismic stress changes agree well with postearthquake stresses measured by hydrofracturing in deep boreholes near Hirabayashi and Ogura on Awaji Island. Our results indicate that the Nojima fault slipped at very low shear stress, and fractional stress drop was complete near the surface and about 32% below depths of 2 km. Our results at depth depend on the accuracy of the rake rotations in Yoshida's model, which are probably correct on the Nojima fault but debatable on the Rokko fault. Our results imply that curved or cross-cutting fault striations can be formed in a single earthquake, contradicting a common assumption of structural geology.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/BSSA0880020413","issn":"00371106","usgsCitation":"Spudich, P., Guatteri, M., Otsuki, K., and Minagawa, J., 1998, Use of fault striations and dislocation models to infer tectonic shear stress during the 1995 Hyogo-Ken Nanbu (Kobe) earthquake: Bulletin of the Seismological Society of America, v. 88, no. 2, p. 413-427, https://doi.org/10.1785/BSSA0880020413.","productDescription":"13 p.","startPage":"413","endPage":"427","numberOfPages":"15","costCenters":[],"links":[{"id":229851,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Japan","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              134.38242996352392,\n              34.880736815877626\n            ],\n            [\n              134.38242996352392,\n              34.45605646653874\n            ],\n            [\n              135.64585769789886,\n              34.45605646653874\n            ],\n            [\n              135.64585769789886,\n              34.880736815877626\n            ],\n            [\n              134.38242996352392,\n              34.880736815877626\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"88","issue":"2","noUsgsAuthors":false,"publicationDate":"1998-04-01","publicationStatus":"PW","scienceBaseUri":"505bbefce4b08c986b3298d4","contributors":{"authors":[{"text":"Spudich, P.","contributorId":85700,"corporation":false,"usgs":true,"family":"Spudich","given":"P.","affiliations":[],"preferred":false,"id":388609,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guatteri, Mariagiovanna","contributorId":29979,"corporation":false,"usgs":true,"family":"Guatteri","given":"Mariagiovanna","email":"","affiliations":[],"preferred":false,"id":388606,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Otsuki, K.","contributorId":41616,"corporation":false,"usgs":true,"family":"Otsuki","given":"K.","email":"","affiliations":[],"preferred":false,"id":388608,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Minagawa, J.","contributorId":31141,"corporation":false,"usgs":true,"family":"Minagawa","given":"J.","email":"","affiliations":[],"preferred":false,"id":388607,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Determinations of paleointensity obtained at eight sites depict the same overall pattern as the previous results for the same period in Hawaii, although the overall average field intensity appears to be lower. Since the present results were determined at higher temperatures than in the previous studies, this discrepancy raises questions regarding the selection of low versus high-temperature segments that are usually made for absolute paleointensity. The virtual dipole moments are similar to those displayed by the worldwide data set obtained from dated lava flows. When averaged within finite time intervals, the worldwide values match nicely the variations of the Sint-200 synthetic record of relative paleointensity and confirm the overall decrease of the dipole field intensity during most of this period. The convergence between the existing records at Hawaii and the rest of the world does not favour the presence of persistent strong non-dipole components beneath Hawaii for this period.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earth and Planetary Science Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0012-821X(98)00133-2","issn":"0012821X","usgsCitation":"Valet, J., Tric, E., Herrero-Bervera, E., Meynadier, L., and Lockwood, J.P., 1998, Absolute paleointensity from Hawaiian lavas younger than 35 ka: Earth and Planetary Science Letters, v. 161, no. 1-4, p. 19-32, https://doi.org/10.1016/S0012-821X(98)00133-2.","startPage":"19","endPage":"32","numberOfPages":"14","costCenters":[],"links":[{"id":206964,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0012-821X(98)00133-2"},{"id":231390,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"161","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e64be4b0c8380cd47311","contributors":{"authors":[{"text":"Valet, J.-P.","contributorId":93239,"corporation":false,"usgs":true,"family":"Valet","given":"J.-P.","email":"","affiliations":[],"preferred":false,"id":387493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tric, E.","contributorId":27637,"corporation":false,"usgs":true,"family":"Tric","given":"E.","email":"","affiliations":[],"preferred":false,"id":387491,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Herrero-Bervera, E.","contributorId":56828,"corporation":false,"usgs":true,"family":"Herrero-Bervera","given":"E.","affiliations":[],"preferred":false,"id":387492,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Meynadier, L.","contributorId":98071,"corporation":false,"usgs":true,"family":"Meynadier","given":"L.","email":"","affiliations":[],"preferred":false,"id":387494,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lockwood, J.

In an effort to control the abundance of ruffe and limit dispersal, a top-down control strategy using predators was implemented in 1989.  We used bioenergetics modeling to examine the efficacy of top-down control in the St. Louis River from 1991 to 1994.  Five predators--northern pike (<i>Esox lucius</i>), walleye (<i>Stizostedion vitreum vitreum</i>), smallmouth bass (<i>Micropterus dolomieui</i>), brown bullhead (<i>Ictalurus nebulosus</i>), and yellow perch (<i>Perca flavescens</i>)--were modeled to determine their consumption of ruffe and four other native prey species-spottail shiner (<i>Notropis hudsonius</i>), emerald shiner (<i>Notropis atherinoides</i>), yellow perch (<i>Perca flavescens</i>), and black crappie (<i>Pomoxis nigromaculatus</i>). Although predators ate as much as 47% of the ruffe biomass in 1 year, they were not able to halt the increase in ruffe abundance.  The St. Louis River is an open system that allows predators to move freely out of the system, and the biomass of managed predators did not increase.  A selectivity index showed all five predators selected the native prey and avoided ruffe. The St. Louis River has several predator and prey species creating many complex predator-prey interactions; and top-down control of ruffe by the predators examined in this study did not occur.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0380-1330(98)70824-X","usgsCitation":"Mayo, K.R., Selgeby, J.H., and McDonald, M., 1998, A bioenergetics modeling evaluation of top-down control of ruffe in the St. Louis River, western Lake Superior: Journal of Great Lakes Research, v. 24, no. 2, p. 329-342, https://doi.org/10.1016/S0380-1330(98)70824-X.","productDescription":"p. 329-342","startPage":"329","endPage":"342","numberOfPages":"13","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133645,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266587,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0380-1330(98)70824-X"}],"volume":"24","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b1283","contributors":{"authors":[{"text":"Mayo, Kathleen R.","contributorId":101237,"corporation":false,"usgs":true,"family":"Mayo","given":"Kathleen","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":309442,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Selgeby, James H.","contributorId":89828,"corporation":false,"usgs":true,"family":"Selgeby","given":"James","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":309441,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McDonald, Michael E.","contributorId":42178,"corporation":false,"usgs":true,"family":"McDonald","given":"Michael E.","affiliations":[],"preferred":false,"id":309440,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These geophysical surveys were limited to the southern and western parts of the island because of problems with access and cultural metallic objects such as reinforced concrete roadways on the eastern part of the island. The geophysical data were supplemented with the location of a freshwater spring found by scuba divers at a depth of about 20 m below sea level along the northern coast of the island. The geophysical data suggest that the freshwater lens has a maximum thickness of 20 m in the southern half of the island. The freshwater lens is not thickest at the center of the island but nearer the southwestern edge in Quaternary deposits and the eastern edge of the island in the Tertiary carbonates. This finding indicates that the groundwater flow paths on Isla de Mona are not radially summetrical from the center of the island to the ocean. The asymmetry of the freshwater lens indicates that the differences in hydraulic conductivity are a major factor in determining the shape of the freshwater lens.

Hens with broods in big sagebrush/bunchgrass habitat (Artemisia tridentata/Agropyron spicatum) selected for greater food forb cover, total forb cover, and lower shrub heights; broods in altered big sagebrush/bunchgrass habitats selected greater tall grass cover and vertical cover height; broods in grassland showed no preference for any measured vegetation characteristics. During the early rearing period (post-hatching-6 wk) each year, broods selected sagebrush/bunchgrass. Broods in 1993 made greater use of grasslands than in 1992 and selected grassland during the late brood-rearing period (7-12 wk). Broods selected for sagebrush/bunchgrass during midday, but 52% of brood locations in the afternoon were in grassland.

Analyses of remote sensing and in situ observations acquired by the rover confirmed inferences made from orbital and simulated descent images that the Sunshine Volcanic Field is composed of basalt flows. Rover data confirmed the idea that Lavic Lake is a recharge playa and that an alluvial fan composed of sediments with felsic compositions has prograded onto the playa.

Recent reports, however, suggest that it could play a major role in the evolution and biogeography of recent corals. We investigated the calcification rates of five colonies of the zooxanthellate coral Stylophora pistillata in synthetic seawater using the alkalinity anomaly technique. Changes in aragonite saturation from 98% to 585% were obtained by manipulating the calcium concentration. The results show a nonlinear increase in calcification rate as a function of aragonite saturation level. Calcification increases nearly 3-fold when aragonite saturation increases from 98% to 390%, i.e., close to the typical present saturation state of tropical seawater. There is no further increase of calcification at saturation values above this threshold. Preliminary data suggest that another coral species, Acropora sp., displays a similar behaviour. These experimental results suggest: (l) that the rate of calcification does not change significantly within the range of saturation levels corresponding to the last glacial-interglacial cycle, and (2) that it may decrease significantly in the future as a result of the decrease in the saturation level due to anthropogenic release of CO2 into the atmosphere. Experimental studies that control environmental conditions and seawater composition provide unique opportunities to unravel the response of corals to global environmental changes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Global and Planetary Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0921-8181(98)00035-6","issn":"09218181","usgsCitation":"Gattuso, J., Frankignoulle, M., Bourge, I., Romaine, S., and Buddemeier, R., 1998, Effect of calcium carbonate saturation of seawater on coral calcification: Global and Planetary Change, v. 18, no. 1-2, p. 37-46, https://doi.org/10.1016/S0921-8181(98)00035-6.","startPage":"37","endPage":"46","numberOfPages":"10","costCenters":[],"links":[{"id":206566,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0921-8181(98)00035-6"},{"id":230235,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a05c6e4b0c8380cd50f51","contributors":{"authors":[{"text":"Gattuso, J.-P.","contributorId":61194,"corporation":false,"usgs":true,"family":"Gattuso","given":"J.-P.","email":"","affiliations":[],"preferred":false,"id":387665,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Frankignoulle, M.","contributorId":39968,"corporation":false,"usgs":true,"family":"Frankignoulle","given":"M.","email":"","affiliations":[],"preferred":false,"id":387663,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bourge, I.","contributorId":10948,"corporation":false,"usgs":true,"family":"Bourge","given":"I.","email":"","affiliations":[],"preferred":false,"id":387662,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Romaine, S.","contributorId":50684,"corporation":false,"usgs":true,"family":"Romaine","given":"S.","email":"","affiliations":[],"preferred":false,"id":387664,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Buddemeier, R.

However, there are reasons to doubt its efficacy in explaining the observed, impressively detailed adaptive responses of organisms to day-to-day changes in their surroundings. Also, the theory lacks a clear mechanism to account for both plasticity and canalization. In effect, there is a growing sentiment that the neo-Darwinian paradigm is incomplete, that something more than genetic structure, mutation, genetic drift, and the action of natural selection is required to explain organismal behavior. In this paper we extend the view of organisms as complex self-organizing entities by arguing that basic physical laws, coupled with the acquisitive nature of organisms, makes adaptation all but tautological. That is, much adaptation is an unavoidable emergent property of organisms' complexity and, to some a significant degree, occurs quite independently of genomic changes wrought by natural selection. For reasons that will become obvious, we refer to this assertion as the attractor hypothesis. The arguments also clarify the concept of \"adaptation.\" Adaptation across generations, by natural selection, equates to the (game theoretic) maximization of fitness (the success with which one individual produces more individuals), while self-organizing based adaptation, within generations, equates to energetic efficiency and the matching of intake and biosynthesis to need. Finally, we discuss implications of the attractor hypothesis for a wide variety of genetical and physiological phenomena, including genetic architecture, directed mutation, genetic imprinting, paramutation, hormesis, plasticity, optimality theory, genotype-phenotype linkage and puncuated equilibrium, and present suggestions for tests of the hypothesis. ?? 1998 American Institute of Physics.","language":"English","publisher":"AIP Publishing","doi":"10.1063/1.166355","issn":"10541500","usgsCitation":"Emlen, J., Freeman, D., Mills, A., and Graham, J., 1998, How organisms do the right thing: The attractor hypothesis: Chaos, v. 8, no. 3, p. 717-726, https://doi.org/10.1063/1.166355.","productDescription":"10 p.","startPage":"717","endPage":"726","numberOfPages":"10","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":230950,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":265845,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1063/1.166355"}],"volume":"8","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3253e4b0c8380cd5e700","contributors":{"authors":[{"text":"Emlen, J.M.","contributorId":63979,"corporation":false,"usgs":true,"family":"Emlen","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":386593,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Freeman, D.C.","contributorId":21309,"corporation":false,"usgs":true,"family":"Freeman","given":"D.C.","email":"","affiliations":[],"preferred":false,"id":386591,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mills, A.","contributorId":33085,"corporation":false,"usgs":true,"family":"Mills","given":"A.","email":"","affiliations":[],"preferred":false,"id":386592,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Graham, J.H.","contributorId":77322,"corporation":false,"usgs":true,"family":"Graham","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":386594,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

A vertical EM profiling experiment was done at the University of California Richmond Field Station, where we simulated a brine spill plume by creating a saline water injection zone at a depth of 30 m. The data acquisition mode was analogous to the reverse vertical seismic profiling (VSP) configuration used for seismic measurements in that the EM transmitter traversed the PVC-cased borehole used for fluid injection and extraction while the receivers were deployed on the surface. The EM measurements were made at 9.6 kHz with an accuracy of 1% in signal amplitude and 1??in signal phase. Observations were taken at 5-m intervals along two intersecting profiles that were centered on the injection well and extended for 60 m on either side of it. The presence of the injected salt water, at the expected 30 m depth, was indicated clearly by differences between the pre-extraction and postextraction data. A limited amount of numerical modeling showed that the experimental data were consistent with the presence of two superposed saline plumes. The uppermost of these, located at 26 m depth, was 2 m thick and had an area of 30 m2. The lower plume, located at 30 m, is the major cause of the observed anomally, as it has an areal extent of 120 m2 and a thickness of 3 m. Surprisingly, the measurements were very sensitive to the presence of cultural surficial conductivity anomalies.

Ichthyoplankton samples were collected in 1993 during day and night in the main-channel and a backwater of the lower Columbia River, and in a tributary, the Deschutes River. Fish embryos and larvae collected in the main-channel Columbia River were primarily (85.6%) of native taxa (peamouth Mylocheilus caurinus, northern squawfish Ptychocheilus oregonensis, suckers Catostomus spp., and sculpins Cottus spp.), with two introduced species (American shad Alosa sapidissima and common carp Cyprinus carpio) comprising a smaller percentage of the catch (13.3%). Similarly, in the Deschutes River native taxa [lampreys (Petromyzontidae), minnows (Cyprinidae), and suckers Catostomus spp.] dominated collections (99.5% of the catch). In contrast, 83.5% of embryos and larvae in the Columbia River backwater were of introduced taxa [American shad, common carp, and sunfishes (Centrarchidae)]. In all locations, all dominant taxa except sculpins were collected in significantly greater proportions at night. Taxon-specific differences in proportions of embryos and larvae collected at night can in some instances be related to life history styles. In the main-channel Columbia River, northern squawfish and peamouth were strongly nocturnal and high proportions still had yolksacs, suggesting that they had recently hatched and were drifting downriver to rearing areas. In contrast, sculpin abundances were similar during day and night, and sculpins mostly had depleted yolksacs, indicating sculpins were feeding and rearing in offshore limnetic habitats. Taxon-specific diel abundance patterns and their causes must be considered when designing effective sampling programs for fish embryos and larvae.","language":"English","publisher":"Kluwer Academic

The prognostic analysis involved the High-Resolution Biosphere Model, a prognostic terrestrial biosphere model, and the coupled vegetation fire module, which together produce a prognostic data set of biomass burning. The diagnostic analysis involved the Simple Diagnostic Biosphere Model (SDBM) and the&nbsp;</span><i>Hao and Liu</i><span>&nbsp;[1994] diagnostic data set of biomass burning, which have been scaled to global 2 and 4 Pg C yr</span><sup>−1</sup><span>, respectively. The monthly carbon exchange fields between the atmosphere and the biosphere with a spatial resolution of 0.5° × 0.5°, the seasonal atmosphere-ocean exchange fields, and the emissions from fossil fuels have been coupled to the three-dimensional atmospheric transport model TM2. We have chosen eight monitoring stations of the National Oceanic and Atmospheric Administration network to compare the predicted seasonal atmospheric CO</span><sub>2</sub><span>&nbsp;signals with those deduced from atmosphere-biosphere carbon exchange fluxes without any contribution from biomass burning. The prognostic analysis and the diagnostic analysis with global burning emissions of 4 Pg C yr</span><sup>−1</sup><span>&nbsp;agree with respect to the change in the amplitude of the seasonal CO</span><sub>2</sub><span>&nbsp;concentration introduced through biomass burning. We find that the seasonal CO</span><sub>2</sub><span>&nbsp;signal at stations in higher northern latitudes (north of 30°N) is marginally influenced by biomass burning. For stations in tropical regions an increase in the CO</span><sub>2</sub><span>&nbsp;amplitude of more than 1 ppmv (up to 50% with respect to the observed trough to peak amplitude) has been calculated. Biomass burning at stations farther south accounts for an increase in the CO</span><sub>2</sub><span>&nbsp;amplitude of up to 59% (0.6 ppmv). A change in the phase of the seasonal CO</span><sub>2</sub><span>&nbsp;signal at tropical and southern stations has been shown to be strongly influenced by the onset of biomass burning in southern tropical Africa and America. Comparing simulated and observed seasonal CO</span><sub>2</sub><span>&nbsp;signals, we find higher discrepancies at southern tropical stations if biomass burning emissions are included. This is caused by the additional increase in the amplitude in the prognostic analysis and a phase shift in a diagnostic analysis. In contrast, at the northern tropical stations biomass burning tends to improve the estimates of the seasonal CO</span><sub>2</sub><span>&nbsp;signal in the prognostic analysis because of strengthening of the amplitude. Since the SDBM predicts the seasonal CO</span><sub>2</sub><span>&nbsp;signal reasonably well for the northern hemisphere tropical stations, no general improvement of the fit occurs if biomass burning emissions are considered.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/98GB02336","usgsCitation":"Wittenberg, U., Heimann, M., Esse, G., McGuire, A., and Sauf, W., 1998, On the influence of biomass burning on the seasonal CO2 signal as observed at monitoring stations: Global Biogeochemical Cycles, v. 12, no. 3, p. 531-544, https://doi.org/10.1029/98GB02336.","productDescription":"14 p.","startPage":"531","endPage":"544","numberOfPages":"14","costCenters":[],"links":[{"id":487333,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/0vs3f7vr","text":"External Repository"},{"id":231227,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6dd8e4b0c8380cd75356","contributors":{"authors":[{"text":"Wittenberg, U.","contributorId":63990,"corporation":false,"usgs":true,"family":"Wittenberg","given":"U.","email":"","affiliations":[],"preferred":false,"id":386785,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Heimann, Martin","contributorId":76497,"corporation":false,"usgs":true,"family":"Heimann","given":"Martin","affiliations":[],"preferred":false,"id":386787,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Esse, G.","contributorId":70143,"corporation":false,"usgs":true,"family":"Esse","given":"G.","email":"","affiliations":[],"preferred":false,"id":386786,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McGuire, A.

We detected 64% of these predicted grassland species and 71% of predicted coastal scrub species. For the habitats combined, we detected 65% of the species predicted to be present by the CWHR System. We detected 68% of the mammals, 62% of the reptiles, and 50% of the amphibians predicted for these habitats. The CWHR System theoretically predicts absence rather than presence, since it is assumed that all 288 regularly occurring mammals, reptiles, and amphibians occur anywhere unless one can argue that a specific habitat, location, or habitat element is not available. By including predictions of species absence in the assessment of model performance, observed accuracy of the CWHR model predictions increased to 96% for both habitats.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"California Fish and Game","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00081078","usgsCitation":"Howell, J.A., and Barrett, R., 1998, California Wildlife Habitat Relationships System: A test in coastal scrub and annual grassland habitats: California Fish and Game, v. 84, no. 2, p. 74-87.","startPage":"74","endPage":"87","numberOfPages":"14","costCenters":[],"links":[{"id":231422,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"84","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f31ce4b0c8380cd4b5e8","contributors":{"authors":[{"text":"Howell, J.

In contrast to the Leverett J-function approach, this methodology (hereby termed flow-unit-derived initial oil saturation or FUSOI) determines the distributions of the initial oil saturations from a measure of the mean hydraulic radius, referred to as the flow zone indicator (FZI). FZI is derived from porosity and permeability data. In the FUSOI approach, capillary pressure parameters, S(wir), P(d), and ??, derived from the Brooks and Corey (1966) model [Brooks, R.H., Corey, A.T., 1966. Hydraulic properties of porous media, Hydrology Papers, Colorado State Univ., Ft. Collins, No. 3, March.], are correlated to the FZI. Subsequent applications of these parameters then permit the computation of improved hydrocarbon saturations as functions of FZI and height above the free water level (FWL). This technique has been successfully applied in the Mississippian Aux Vases Sandstone reservoirs of the Illinois Basin (USA). The Aux Vases Zeigler field (Franklin County, IL, USA) was selected for a field-wide validation of this FUSOI approach because of the availability of published studies. With the initial oil saturations determined on a depth-by-depth basis in cored wells, it was possible to geostatistically determine the three-dimensional (3-D) distributions of initial oil saturations in the Zeigler field. The original oil-in-place (OOIP), computed from the detailed initialization of the 3-D reservoir simulation model of the Zeigler field, was found to be within 5.6% of the result from a rigorous material balance method.An improved technique for modeling the initial reservoir hydrocarbon saturation distributions is presented.

Distance estimation and program DISTANCE were used to provide estimates of density from the trapping-web data. Mean density based on trapping webs was 9.5 mongooses/ha (range, 5.9-10.2/ha); estimates had coefficients of variation ranging from 29.82-31.58% (X?? = 30.46%). Mark-recapture models were used to estimate abundance, which was converted to density using estimates of effective trap area. Tests of model assumptions provided by CAPTURE indicated pronounced heterogeneity in capture probabilities and some indication of behavioral response and variation over time. Mean estimated density was 1.80 mongooses/ha (range, 1.37-2.15/ha) with estimated coefficients of variation of 4.68-11.92% (X?? = 7.46%). Estimates of density based on mark-recapture data depended heavily on assumptions about animal home ranges; variances of densities also may be underestimated, leading to unrealistically narrow confidence intervals. Estimates based on trap webs require fewer assumptions, and estimated variances may be a more realistic representation of sampling variation. Because trap webs are established easily and provide adequate data for estimation in a few sample occasions, the method should be efficient and reliable for estimating densities of mongooses.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00222372","usgsCitation":"Corn, J., and Conroy, M., 1998, Estimation of density of mongooses with capture-recapture and distance sampling: Journal of Mammalogy, v. 79, no. 3, p. 1009-1015.","startPage":"1009","endPage":"1015","numberOfPages":"7","costCenters":[],"links":[{"id":230233,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"79","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0b82e4b0c8380cd52758","contributors":{"authors":[{"text":"Corn, J.L.","contributorId":72964,"corporation":false,"usgs":true,"family":"Corn","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":387654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conroy, M.J.","contributorId":84690,"corporation":false,"usgs":true,"family":"Conroy","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":387655,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
