Geospatial data sharing is an increasingly important subject as large amount of data is produced by a variety of sources, stored in incompatible formats, and accessible through different GIS applications. Past efforts to enable sharing have produced standardized data format such as GML and data access protocols such as Web Feature Service (WFS). While these standards help enabling client applications to gain access to heterogeneous data stored in different formats from diverse sources, the usability of the access is limited due to the lack of data semantics encoded in the WFS feature types. Past research has used ontology languages to describe the semantics of geospatial data but ontology-based queries cannot be applied directly to legacy data stored in databases or shapefiles, or to feature data in WFS services. This paper presents a method to enable ontology query on spatial data available from WFS services and on data stored in databases. We do not create ontology instances explicitly and thus avoid the problems of data replication. Instead, user queries are rewritten to WFS getFeature requests and SQL queries to database. The method also has the benefits of being able to utilize existing tools of databases, WFS, and GML while enabling query based on ontology semantics.

A high-resolution, continuous seawater calcium isotope ratio curve from marine (pelagic) barite reveals distinct features in the evolution of the seawater calcium isotopic ratio suggesting changes in seawater calcium concentrations. The most pronounced increase in the ??44/40Ca value of seawater (of 0.3 per mil) occurred over roughly 4 million years following a period of low values around 13 million years ago. The major change in marine calcium corresponds to a climatic transition and global change in the carbon cycle and suggests a reorganization of the global biogeochemical system.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1126/science.1163614","issn":"00368","usgsCitation":"Griffith, E., Paytan, A., Caldeira, K., Bullen, T., and Thomas, E., 2008, A dynamic marine calcium cycle during the past 28 million years: Science, v. 322, no. 5908, p. 1671-1674, https://doi.org/10.1126/science.1163614.","startPage":"1671","endPage":"1674","numberOfPages":"4","costCenters":[],"links":[{"id":214056,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1126/science.1163614"},{"id":241743,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"322","issue":"5908","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e3c8e4b0c8380cd4620f","contributors":{"authors":[{"text":"Griffith, E.M.","contributorId":88958,"corporation":false,"usgs":true,"family":"Griffith","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":438218,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paytan, A.","contributorId":98926,"corporation":false,"usgs":true,"family":"Paytan","given":"A.","affiliations":[],"preferred":false,"id":438219,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Caldeira, K.","contributorId":17823,"corporation":false,"usgs":true,"family":"Caldeira","given":"K.","email":"","affiliations":[],"preferred":false,"id":438215,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bullen, T.D.","contributorId":79911,"corporation":false,"usgs":true,"family":"Bullen","given":"T.D.","email":"","affiliations":[],"preferred":false,"id":438217,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Thomas, E.","contributorId":64467,"corporation":false,"usgs":true,"family":"Thomas","given":"E.","email":"","affiliations":[],"preferred":false,"id":438216,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70033172,"text":"70033172 - 2008 - Erosion properties of cohesive sediments in the Colorado River in Grand Canyon","interactions":[],"lastModifiedDate":"2012-03-12T17:21:38","indexId":"70033172","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3301,"text":"River Research and Applications","active":true,"publicationSubtype":{"id":10}},"title":"Erosion properties of cohesive sediments in the Colorado River in Grand Canyon","docAbstract":"Cohesive sediment deposits characterized by a high fraction of mud (silt plus clay) significantly affect the morphology and ecosystem of rivers. Potentially cohesive sediment samples were collected from deposits in the Colorado River in Marble and Grand Canyons. The erosion velocities of these samples were measured in a laboratory flume under varying boundary shear stresses. The non-dimensional boundary shear stress at which erosion commenced showed a systematic deviation from that of non-cohesive sediments at mud fractions greater than 0.2. An empirical relation for the boundary shear stress threshold of erosion as a function of mud fraction was proposed. The mass erosion rate was modelled using the Ariathurai-Partheniades equation. The erosion rate parameter of this equation was found to be a strong function of mud fraction. Under similar boundary shear stress and sediment supply conditions in the Colorado River, cohesive lateral eddy deposits formed of mud fractions in excess of 0.2 will erode less rapidly than non-cohesive deposits.

However, do aggressiveness, voracity and boldness of the invader depend on the presence of an ecologically similar native competitor in the invaded community? We conducted four behavioral assays to compare aggression, foraging voracity, threat response and boldness to forage under predation risk of multiple populations of exotic signal crayfish Pacifastacus leniusculus across its native and invaded range with and without a native congener, the Shasta crayfish P. fortis. We predicted that signal crayfish from the invaded range and sympatric with a native congener (IRS) should be more aggressive to outcompete a close competitor than populations from the native range (NR) or invaded range and allopatric to a native congener (IRA). Furthermore, we predicted that IRS populations of signal crayfish should be more voracious, but less bold to forage under predation risk since native predators and prey likely possess appropriate behavioral responses to the invader. Contrary to our predictions, results indicated that IRA signal crayfish were more aggressive towards conspecifics and more voracious and active foragers, yet also bolder to forage under predation risk in comparison to NR and IRS populations, which did not differ in behavior. Higher aggression/voracity/ boldness was positively correlated with prey consumption rates, and hence potential impacts on prey. We suggest that the positive correlations between aggression/voracity/boldness are the result of an overall aggression syndrome. Results of stream surveys indicated that IRA streams have significantly lower prey biomass than in IRS streams, which may drive invading signal crayfish to be more aggressive/voracious/bold to acquire resources to establish a population. ?? 2008 The Authors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Oikos","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1600-0706.2008.16578.x","issn":"00301","usgsCitation":"Pintor, L., Sih, A., and Bauer, M., 2008, Differences in aggression, activity and boldness between native and introduced populations of an invasive crayfish: Oikos, v. 117, no. 11, p. 1629-1636, https://doi.org/10.1111/j.1600-0706.2008.16578.x.","startPage":"1629","endPage":"1636","numberOfPages":"8","costCenters":[],"links":[{"id":214511,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1600-0706.2008.16578.x"},{"id":242245,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"117","issue":"11","noUsgsAuthors":false,"publicationDate":"2008-10-28","publicationStatus":"PW","scienceBaseUri":"505a00ece4b0c8380cd4f9c0","contributors":{"authors":[{"text":"Pintor, L.M.","contributorId":12703,"corporation":false,"usgs":true,"family":"Pintor","given":"L.M.","email":"","affiliations":[],"preferred":false,"id":440897,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sih, A.","contributorId":30837,"corporation":false,"usgs":true,"family":"Sih","given":"A.","email":"","affiliations":[],"preferred":false,"id":440899,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bauer, M.L.","contributorId":16655,"corporation":false,"usgs":true,"family":"Bauer","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":440898,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70033164,"text":"70033164 - 2008 - Influence of Harbor construction on downcoast morphological evolution: Santa Barbara, California","interactions":[],"lastModifiedDate":"2012-03-12T17:21:34","indexId":"70033164","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":24,"text":"Conference Paper"},"publicationSubtype":{"id":19,"text":"Conference Paper"},"title":"Influence of Harbor construction on downcoast morphological evolution: Santa Barbara, California","docAbstract":"Sand impoundment caused by construction of the Santa Barbara Harbor in the 1920s, created an erosion wave that impacted downcoast Carpinteria Beach. Historic beach and shoreline changes were analyzed to understand continuing erosion using a combination of historic air photos, lidar, and physical measurements. The long-term analyses show a clockwise rotation with erosion of - 0.35 m/yr at the updrift end and accretion downdrift of 0.3 m/yr. Storm impacts measured before and after the 1982-83 and 1997-98 El Ni??o events show similar rotation patterns, providing evidence that El Ni??os may be driving coastal evolution. Differences in shoreline responses between El Nino events show that the erosion hotspot migrated downdrift following construction of a revetment after the 1982-83 storms. Seasonal field measurements in the winter show beach narrowing while sediment coarsen variably alongshore. The coarsest materials and erosion hotspot are co-located at the end of the revetment on the city beach.

Borrow pits dredged about 30??years ago to provide sand for the nourishment project have a significant influence on project performance and formation of erosional hot spots. It was found that the main processes controlling beach response to these offshore bathymetric features were feedbacks between wave forces (roller force or alongshore component of the radiation stress), pressure gradients due to differentials in wave set-up/set-down and bed shear stress. Modeling results also indicated that backfilling of selected borrow sites showed a net positive effect within the beach fill limits and caused a reduction in the magnitude of hot spot erosion. ?? 2008 Elsevier B.V.

Primary drivers for the availability of water are landscape changes and patterns, and the processes affecting the timing, magnitude, and intensity of precipitation, including global climate change. The degradation of air, land, and water in one part of a drainage basin can have negative effects on users downstream; the time and space scales of the effects are determined by the residence time along the various hydrological pathways. Hydrology affects transport, deposition, and recycling of inorganic materials and sediment. These components affect biota and associated ecosystem processes, which rely on sustainable flows throughout a drainage basin. Human activities on all spatial scales affect both water quantity and quality, and some human activities can have a disproportionate effect on an entire drainage basin. Aquatic systems have been continuously modified by agriculture, through land-use change, irrigation and navigation, disposal of urban, mining, and industrial wastes, and engineering modifications to the environment. Interdisciplinary integrated basin studies within the last several decades have provided a more comprehensive understanding of the linkages among air, land, and water resources. This understanding, coupled with environmental monitoring, has evolved a more multidisciplinary integrated approach to resource management, particularly within drainage basins.","largerWorkTitle":"IAHS-AISH Publication","conferenceTitle":"River Basins - From Hydrological Science to Water Management","conferenceLocation":"Paris","language":"English","issn":"01447","isbn":"9781901502695","usgsCitation":"Peters, N., 2008, Water-quality monitoring and process understanding in support of environmental policy and management, in IAHS-AISH Publication, no. 323, Paris, p. 93-109.","startPage":"93","endPage":"109","numberOfPages":"17","costCenters":[],"links":[{"id":241672,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"323","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bce33e4b08c986b32e29e","contributors":{"authors":[{"text":"Peters, N.E.","contributorId":33332,"corporation":false,"usgs":true,"family":"Peters","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":438203,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70033484,"text":"70033484 - 2008 - Abundance and modes of occurrence of mercury in some low-sulfur coals from China","interactions":[],"lastModifiedDate":"2012-03-12T17:21:27","indexId":"70033484","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2033,"text":"International Journal of Coal Geology","active":true,"publicationSubtype":{"id":10}},"title":"Abundance and modes of occurrence of mercury in some low-sulfur coals from China","docAbstract":"Mercury (Hg) is one of the hazardous trace elements in coal. Mercury in coal is almost totally emitted into the atmosphere during coal combustion. Especially for utilities burning low-sulfur coals that do not require scrubbers, Hg reduction will be neglected. Hg abundances of 52 low-sulfur coal samples from different coalfields in six provinces of China were determined by a flow injection mercury system (FIMS). The results show that Hg abundances in selected low-sulfur coals range from 0.03??ppm to 0.79??ppm, with an arithmetic mean of 0.24??ppm, which is higher than that of average Chinese coals (0.19??ppm). Correlation analysis and sequential extraction procedures are performed to study possible modes of occurrence of Hg in low-sulfur coals. Modes of occurrence of Hg are variable in low-sulfur coals, and the sulfide-bound and organic-bound Hg may be the dominant forms. In addition, the silicate-bound Hg may be the main form in some of these coals because of magmatic intrusion. ?? 2007 Elsevier B.V.

The metamorphic recrystallization of iron-formation locally produced iron-rich amphiboles and other fibrous iron-silicate minerals. The presence of these minerals in iron-formation along the eastern part of what is known as the Mesabi Iron Range, and their potential liberation by iron mining has raised environmental health concerns.

The effects of metamorphism are most pronounced within a few kilometers of the contact, and decrease progressively away from it. The contact aureole has been divided into four metamorphic zones-each characterized by the composition and crystal structure of the metamorphic minerals it contains. The recrystallization of iron-formation to iron-rich amphibole minerals (grunerite and cummingtonite) and iron-pyroxene minerals (hedenbergite and ferrohypersthene) is best developed in zones that are most proximal to the Duluth Complex contact. ?? 2007 Elsevier Inc.

The rim is 120–220 m wide and is surrounded by a dark annulus reaching an average of 590 m beyond the raised rim. Comparison between observed morphology and that expected for pristine craters 500–750 m across indicates that the original, pristine crater was close to 600 m in diameter. Hence, the crater has been erosionally widened by ∼150 m and infilled by ∼50 m of sediments. Eolian processes are responsible for most crater modification, but lesser mass wasting or gully activity contributions cannot be ruled out. Erosion by prevailing winds is most significant along the exposed rim and upper walls and accounts for ∼50 m widening across a WNW–ESE diameter. The volume of material eroded from the crater walls and rim is ∼20% less than the volume of sediments partially filling the crater, indicating eolian infilling from sources outside the crater over time. The annulus formed when ∼1 m deflation of the ejecta created a lag of more resistant hematite spherules that trapped <10–20 cm of darker, regional basaltic sands. Greater relief along the rim enabled meters of erosion. Comparison between Victoria and regional craters leads to definition of a crater degradation sequence dominated by eolian erosion and infilling over time.

From 1999 through 2005, the Alaska Volcano Observatory (AVO) recorded ∼1700 earthquakes in the vicinity of Great Sitkin, including two ML 4.3 earthquakes that are among the largest events in the AVO catalog. The majority of earthquakes occurred during 2002 and formed two temporally and spatially separate event sequences. The first sequence began on 17 March 2002 and was centered ∼20 km west of the volcano. The second sequence occurred on the southeast flank of Great Sitkin and began 28 May 2002. It was preceded by two episodes of volcanic tremor. Earthquake relocations of this activity on the southeast flank define a vertical planar feature oriented radially from the summit and in the direction of the assumed regional maximum compressive stress due to convergence along the Alaska subduction zone. This swarm may have been caused or accompanied by the emplacement of a dike. Relocations of the mainshock–aftershock sequence occurring west of Great Sitkin are consistent with rupture on a strike-slip fault. Tomographic images support the presence of a vertically dipping fault striking parallel to the direction of convergence in this region. The remaining catalog hypocenters relocate along discrete features beneath the volcano summit; here, low P-wave velocities possibly indicate the presence of magma beneath the volcano.

We combined data from the US Geological Survey National Water-Quality Assessment (NAWQA) program and the US Environmental Protection Agency Wadeable Streams Assessment (WSA) to expand the scope of an existing River InVertebrate Prediction and Classification System (RIVPACS)-type predictive model and to assess the biological condition of streams across the western US in a variety of landuse classes. We used model-derived estimates of taxon-specific probabilities of capture and observed taxon occurrences to identify taxa that were absent from sites where they were predicted to occur (decreasers) and taxa that were present at sites where they were not predicted to occur (increasers). Integration of 87 NAWQA reference sites increased the scope of the existing WSA predictive model to include larger streams and later season sampling. Biological condition at 336 NAWQA test sites was significantly (p < 0.001) associated with basin land use and tended to be lower in basins with intensive landuse modification (e.g., mixed, urban, and agricultural basins) than in basins with relatively undisturbed land use (e.g., forested basins). Of the 437 taxa observed among reference and test sites, 180 (41%) were increasers or decreasers. In general, decreasers had a different set of ecological traits (functional traits or tolerance values) than did increasers. We could predict whether a taxon was a decreaser or an increaser based on just a few traits, e.g., desiccation resistance, timing of larval development, habit, and thermal preference, but we were unable to predict the type of basin land use from trait states present in invertebrate assemblages. Refined characterization of traits might be required before bioassessment data can be used routinely to aid in the diagnoses of the causes of biological impairment. ?? 2008 by The North American Benthological Society.","language":"English","publisher":"University of Chicago Press","doi":"10.1899/07-176.1","issn":"08873","usgsCitation":"Carlisle, D., and Hawkins, C., 2008, Land use and the structure of western US stream invertebrate assemblages: Predictive models and ecological traits: Journal of the North American Benthological Society, v. 27, no. 4, p. 986-999, https://doi.org/10.1899/07-176.1.","productDescription":"14 p.","startPage":"986","endPage":"999","ipdsId":"IP-004069","costCenters":[],"links":[{"id":241324,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oregon, Utah, Washington, Wyoming","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"MultiPolygon\",\"coordinates\":[[[[-104.053249,41.001406],[-102.124972,41.002338],[-102.051292,40.749591],[-102.04192,37.035083],[-102.979613,36.998549],[-103.002247,36.911587],[-103.064423,32.000518],[-106.565142,32.000736],[-106.577244,31.810406],[-106.750547,31.783706],[-108.208394,31.783599],[-108.208573,31.333395],[-111.000643,31.332177],[-114.813613,32.494277],[-114.722746,32.713071],[-117.118868,32.534706],[-117.50565,33.334063],[-118.088896,33.729817],[-118.428407,33.774715],[-118.519514,34.027509],[-119.159554,34.119653],[-119.616862,34.420995],[-120.441975,34.451512],[-120.608355,34.556656],[-120.644311,35.139616],[-120.873046,35.225688],[-120.884757,35.430196],[-121.851967,36.277831],[-121.932508,36.559935],[-121.788278,36.803994],[-121.880167,36.950151],[-122.140578,36.97495],[-122.419113,37.24147],[-122.511983,37.77113],[-122.425942,37.810979],[-122.168449,37.504143],[-122.144396,37.581866],[-122.385908,37.908136],[-122.301804,38.105142],[-122.484411,38.11496],[-122.492474,37.82484],[-122.972378,38.020247],[-123.103706,38.415541],[-123.725367,38.917438],[-123.851714,39.832041],[-124.373599,40.392923],[-124.063076,41.439579],[-124.536073,42.814175],[-124.150267,43.91085],[-123.962887,45.280218],[-123.996766,46.20399],[-123.548194,46.248245],[-124.029924,46.308312],[-124.06842,46.601397],[-123.97083,46.47537],[-123.84621,46.716795],[-124.022413,46.708973],[-124.108078,46.836388],[-123.86018,46.948556],[-124.138035,46.970959],[-124.425195,47.738434],[-124.672427,47.964414],[-124.727022,48.371101],[-123.981032,48.164761],[-122.748911,48.117026],[-122.637425,47.889945],[-123.15598,47.355745],[-122.527593,47.905882],[-122.578211,47.254804],[-122.725738,47.33047],[-122.691771,47.141958],[-122.796646,47.341654],[-122.863732,47.270221],[-122.67813,47.103866],[-122.364168,47.335953],[-122.429841,47.658919],[-122.230046,47.970917],[-122.425572,48.232887],[-122.358375,48.056133],[-122.512031,48.133931],[-122.424102,48.334346],[-122.689121,48.476849],[-122.425271,48.599522],[-122.796887,48.975026],[-104.048736,48.999877],[-104.053249,41.001406]]],[[[-119.789798,34.05726],[-119.5667,34.053452],[-119.795938,33.962929],[-119.916216,34.058351],[-119.789798,34.05726]]],[[[-118.524531,32.895488],[-118.573522,32.969183],[-118.369984,32.839273],[-118.524531,32.895488]]],[[[-118.500212,33.449592],[-118.32446,33.348782],[-118.593969,33.467198],[-118.500212,33.449592]]],[[[-122.519535,48.288314],[-122.66921,48.240614],[-122.400628,48.036563],[-122.419274,47.912125],[-122.744612,48.20965],[-122.664928,48.374823],[-122.519535,48.288314]]],[[[-122.800217,48.60169],[-122.883759,48.418793],[-123.173061,48.579086],[-122.949116,48.693398],[-122.743049,48.661991],[-122.800217,48.60169]]]]},\"properties\":{\"name\":\"Arizona\",\"nation\":\"USA \"}}]}","volume":"27","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4383e4b0c8380cd663c6","contributors":{"authors":[{"text":"Carlisle, D.M.","contributorId":81059,"corporation":false,"usgs":true,"family":"Carlisle","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":437601,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hawkins, C.P.","contributorId":64454,"corporation":false,"usgs":true,"family":"Hawkins","given":"C.P.","email":"","affiliations":[],"preferred":false,"id":437600,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70033071,"text":"70033071 -

Carbonate-bearing rocks had not previously been detected on Mars' surface, but Mars Reconnaissance Orbiter mapping reveals a regional rock layer with near-infrared spectral characteristics that are consistent with the presence of magnesium carbonate in the Nili Fossae region. The carbonate is closely associated with both phyllosilicate-bearing and olivine-rich rock units and probably formed during the Noachian or early Hesperian era from the alteration of olivine by either hydrothermal fluids or near-surface water. The presence of carbonate as well as accompanying clays suggests that waters were neutral to alkaline at the time of its formation and that acidic weathering, proposed to be characteristic of Hesperian Mars, did not destroy these carbonates and thus did not dominate all aqueous environments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1126/science.1164759","issn":"00368","usgsCitation":"Ehlmann, B., Mustard, J., Murchie, S., Poulet, F., Bishop, J., Brown, A., Calvin, W.M., Clark, R.N., Des Marais, D., Milliken, R., Roach, L., Roush, T.L., Swayze, G., and Wray, J., 2008, Orbital identification of carbonate-bearing rocks on Mars: Science, v. 322, no. 5909, p. 1828-1832, https://doi.org/10.1126/science.1164759.","startPage":"1828","endPage":"1832","numberOfPages":"5","costCenters":[],"links":[{"id":476679,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20121016-112524059","text":"External Repository"},{"id":213490,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1126/science.1164759"},{"id":241117,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"322","issue":"5909","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6f2fe4b0c8380cd759a6","contributors":{"authors":[{"text":"Ehlmann, B.L.","contributorId":107837,"corporation":false,"usgs":true,"family":"Ehlmann","given":"B.L.","email":"","affiliations":[],"preferred":false,"id":439267,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mustard, J.F.","contributorId":91605,"corporation":false,"usgs":true,"family":"Mustard","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":439265,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Murchie, S.L.","contributorId":7369,"corporation":false,"usgs":true,"family":"Murchie","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":439255,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Poulet, F.","contributorId":61551,"corporation":false,"usgs":true,"family":"Poulet","given":"F.","email":"","affiliations":[],"preferred":false,"id":439260,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bishop, J.L.","contributorId":83244,"corporation":false,"usgs":true,"family":"Bishop","given":"J.L.","affiliations":[],"preferred":false,"id":439263,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Brown, A.J.","contributorId":54803,"corporation":false,"usgs":true,"family":"Brown","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":439259,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Calvin, W.

An investigation was conducted to determine muscle and liver thiamine content and whole body fatty acid composition in small, medium and large Chinook salmon. Muscle and liver thiamine concentrations were highest in small salmon, and tended to decrease with increasing fish size. Muscle thiamine was higher in fall than spring in large salmon. The high percentage of Chinook salmon (24-32% in fall and 58-71% in spring) with muscle thiamine concentration below 500 pmol/g, which has been associated with loss of equilibrium and death in other Great Lake salmonines, suggest that Chinook appear to rely less on thiamine than other Great Lakes species for which such low concentrations would be associated with thiamine deficiency (Brown et al. 2005b). A positive correlation was observed between liver total thiamine and percent liver lipids (r = 0.53, P < 0.0001, n = 119). In medium and large salmon, liver lipids were observed to be low in fish with less than 4,000 pmol/g liver total thiamine. In individuals with greater than 4,000 pmol/g liver thiamine, liver lipid increased with thiamine concentration. Individual fatty acids declined between fall and spring. Essential omega-3 fatty acids appear to be conserved as lipid content declined. Arachidonic acid (C20:4n6), an essential omega-6 fatty acid was not different between fall and spring, although the sum of omega-6 (Sw6) fatty acids declined over winter. Elevated concentrations of saturated fatty acids (sum) were observed in whole body tissue lipid. In summary, thiamine, a dietary essential vitamin, and individual fatty acids were found to vary in Lake Michigan Chinook salmon by fish size and season of the year.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.3394/0380-1330-34.4.581","issn":"03801","usgsCitation":"Honeyfield, D., Peters, A.K., and Jones, M., 2008, Thiamine and fatty acid content of Lake Michigan Chinook salmon: Journal of Great Lakes Research, v. 34, no. 4, p. 581-589, https://doi.org/10.3394/0380-1330-34.4.581.","startPage":"581","endPage":"589","numberOfPages":"9","costCenters":[],"links":[{"id":241086,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213460,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3394/0380-1330-34.4.581"}],"volume":"34","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb290e4b08c986b3258ab","contributors":{"authors":[{"text":"Honeyfield, D.

Thus, MS is considerably higher in well-drained soils (MS typically 40-80 ?? 10-5 standard international [SI]) compared to poorly drained soils (MS typically 10-25 ?? 10-5 SI) in Illinois, other soil-forming factors being equal. Following calibration to standard soil probings, MS values can be used to rapidly and precisely delineate hydric from nonhydric soils in areas with relatively uniform parent material. Furthermore, soil MS has a moderate to strong association with individual tree species' distribution across soil moisture regimes, correlating inversely with independently reported rankings of a tree species' flood tolerance. Soil MS mapping can thus provide a simple, rapid, and quantitative means for precisely guiding reforestation with respect to plant species' adaptations to soil drainage classes. For instance, in native woodlands of east-central Illinois, Quercus alba , Prunus serotina, and Liriodendron tulipifera predominantly occur in moderately well-drained soils (MS 40-60 ?? 10-5 SI), whereas Acer saccharinum, Carya laciniosa, and Fraxinus pennsylvanica predominantly occur in poorly drained soils (MS <20 ?? 10-5 SI). Using a similar method, an MS contour map was used to guide restoration of mesic, wet mesic, and wet prairie species to pre-settlement distributions at Meadowbrook Park (Urbana, IL, U.S.A.). Through use of soil MS maps calibrated to soil drainage class and native vegetation occurrence, restoration efforts can be conducted more successfully and species distributions more accurately reconstructed at the microecosystem level. ?? 2008 Society for Ecological Restoration International.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Restoration Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1526-100X.2008.00479.x","issn":"10612","usgsCitation":"Grimley, D., Wang, J., Liebert, D., and Dawson, J., 2008, Soil magnetic susceptibility: A quantitative proxy of soil drainage for use in ecological restoration: Restoration Ecology, v. 16, no. 4, p. 657-667, https://doi.org/10.1111/j.1526-100X.2008.00479.x.","startPage":"657","endPage":"667","numberOfPages":"11","costCenters":[],"links":[{"id":241083,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213457,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1526-100X.2008.00479.x"}],"volume":"16","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-11-26","publicationStatus":"PW","scienceBaseUri":"505b9207e4b08c986b319c54","contributors":{"authors":[{"text":"Grimley, D.A.","contributorId":18530,"corporation":false,"usgs":true,"family":"Grimley","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":439244,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wang, J.-S.","contributorId":67297,"corporation":false,"usgs":true,"family":"Wang","given":"J.-S.","email":"","affiliations":[],"preferred":false,"id":439245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Liebert, D.A.","contributorId":11010,"corporation":false,"usgs":true,"family":"Liebert","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":439243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dawson, J.O.","contributorId":77367,"corporation":false,"usgs":true,"family":"Dawson","given":"J.O.","email":"","affiliations":[],"preferred":false,"id":439246,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70033442,"text":"70033442 - 2008 - Sand composition and transport history on a fringing coral reef, Molokai, Hawaii","interactions":[],"lastModifiedDate":"2012-03-12T17:21:31","indexId":"70033442","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":24,"text":"Conference Paper"},"publicationSubtype":{"id":19,"text":"Conference Paper"},"title":"Sand composition and transport history on a fringing coral reef, Molokai, Hawaii","docAbstract":"Composition of sand grains from the beaches, reef flat, and fore reef of south Molokai, Hawaii, provides key information about the origin and transport history of sediment on the reef and adjacent beach. The most common grain types include coralline algae, coral, chemically altered carbonate, and siliciclastic grains. Minor components include calcareous algal plates (Halimeda), mollusk fragments, and foraminifera; in selected areas, these components are abundant. Similarities in composition indicate that sand grains are freely transported between the beach and the reef-flat environments, whereas the fore reef has limited exchange of sand with either the beach or the reef flat. Overall, the calcium carbonate fraction of the sand, silt, and clay increases with distance offshore from 400 to 650 m, where the percentages plateau and remain relatively stable across the fore reef. The calcium carbonate content of bottom sediment indicates that sand transport on the reef flat is generally shore parallel with little shore-normal movement. This study has implications for management of beaches and coastal resources along fringing coral reefs in that it documents the effectiveness of the wide reef flat and reef crest in blocking sand transport with the fore reef. It also indicates that sediment introduced to the inner reef flat is not quickly dispersed seaward and therefore has a relatively high residence time in that setting.","largerWorkTitle":"Journal of Coastal Research","language":"English","doi":"10.2112/06-0699.1","issn":"07490","usgsCitation":"Calhoun, R., and Field, M., 2008, Sand composition and transport history on a fringing coral reef, Molokai, Hawaii, in Journal of Coastal Research, v. 24, no. 5, p. 1151-1160, https://doi.org/10.2112/06-0699.1.","startPage":"1151","endPage":"1160","numberOfPages":"10","costCenters":[],"links":[{"id":214483,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2112/06-0699.1"},{"id":242211,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8690e4b08c986b315ffa","contributors":{"authors":[{"text":"Calhoun, R.S.","contributorId":101840,"corporation":false,"usgs":true,"family":"Calhoun","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":440888,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Field, M.E.","contributorId":27052,"corporation":false,"usgs":true,"family":"Field","given":"M.E.","affiliations":[],"preferred":false,"id":440887,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70033142,"text":"70033142 - 2008 - A survey of the indigenous microbiota (bacteria) in three species of mussels from the Clinch and Holston Rivers, Virginia","interactions":[],"lastModifiedDate":"2016-07-08T12:53:03","indexId":"70033142","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2455,"text":"Journal of Shellfish Research","active":true,"publicationSubtype":{"id":10}},"title":"A survey of the indigenous microbiota (bacteria) in three species of mussels from the Clinch and Holston Rivers, Virginia","docAbstract":"Freshwater mussel conservation efforts by many federal and state agencies have increased in recent years. This has led to a greater number of stream surveys, in which mussel die-offs involving high numbers of dead and moribund animals are being observed and reported with greater frequency. Typically, die-offs have been incidentally observed while research was being done for other purposes, therefore, accurate mortality data have been difficult to obtain. Specifically, seasonal die-offs were noted in localized areas of the Clinch and Holston Rivers, Virginia, and to lesser degrees, in neighboring rivers in this geographic region, including southeast Virginia. The observed mussel species affected were primarily the slabside pearlymussel (Lexingtonia dolabelloides) and to lesser extents, the pheasantshell (Actinonaias pectorosa), rainbow mussel (Villosa iris), and the endangered shiny pigtoe (Fusconaia cor). To determine if a bacterial pathogen might be involved in these recurring mussel die-offs, this study examined characteristics of the indigenous microbiota (bacteria) from healthy mussels from sites on the Clinch and Holston Rivers where die-offs were previously observed. These baseline data will allow for recognition of bacterial pathogens in future mussel die-offs. Means for total bacteria from soft tissues ranged from 1.77 × 105 to 3.55 × 106 cfu/g; whereas, the range in means from fluids was 2.92 × 104 to 8.60 × 105 cfu/mL. A diverse microbiota were recovered, including species that are common in freshwater aquatic environments. The most common bacterial groups recovered were motile Aeromonas spp. and nonfermenting bacteria. Flavobacterium columnare, a pathogen to cool- and warm-water fishes was recovered from one specimen, a Villosa iris from the Clinch River.

In birds, vocal cues appear to be a major component of recognition. Curiously, vocal recognition seems absent or limited in some highly social species such as the black-legged kittiwake, Rissa tridactyla. Using playback experiments, we found that kittiwake chicks recognized their parents vocally, this capacity being detectable as early as 20 days after hatching, the youngest age tested. Mates also recognized each other's long calls. Some birds reacted to their partner's voice when only a part of the long call was played back. Nevertheless, only about a third of the tested birds reacted to their mate's or parents' call and we were unable to detect recognition among neighbours. We discuss the low reactivity of kittiwakes in relation to their cliff-nesting habit and compare our results with evidence of vocal recognition in other larids.

Cembroides) are the focus of questions in taxonomy, palaeoclimatology and modelling of future distributions. The identification of these pines, traditionally classified by one- versus two-needled fascicles, is complicated by populations with both one- and two-needled fascicles on the same tree, and the description of two more recently described one-needled varieties: the fallax-type and californiarum-type. Because previous studies have suggested correlations between needle anatomy and climate, including anatomical plasticity reflecting annual precipitation, we approached this study at the level of the anatomy of individual pine needles rather than species. Location: Western North America. Methods: We synthesized available and new data from field and herbarium collections of needles to compile maps of their current distributions across western North America. Annual frequencies of needle types were compared with local precipitation histories for some stands. Historical North American climates were modelled on a c. 1-km grid using monthly temperature and precipitation values. A geospatial model (ClimLim), which analyses the effect of climate-modulated physiological and ecosystem processes, was used to rank the importance of seasonal climate variables in limiting the distributions of anatomical needle types. Results: The pinyon needles were classified into four distinct types based upon the number of needles per fascicle, needle thickness and the number of stomatal rows and resin canals. The individual needles fit well into four categories of needle types, whereas some trees exhibit a mixture of two needle types. Trees from central Arizona containing a mixture of Pinus edulis and fallax-type needles increased their percentage of fallax-type needles following dry years. All four needle types occupy broader geographical regions with distinctive precipitation regimes. Pinus monophylla and californiarum-type needles occur in regions with high winter precipitation. Pinus edulis and fallax-type needles are found in regions with high monsoon precipitation. Areas supporting californiarum-type and fallax-type needle distributions are additionally characterized by a more extreme May-June drought. Main conclusions: These pinyon needle types seem to reflect the amount and seasonality of precipitation. The single needle fascicle characterizing the fallax type may be an adaptation to early summer or periodic drought, while the single needle of Pinus monophylla may be an adaptation to summer-autumn drought. Although the needles fit into four distinct categories, the parent trees are sometimes less easily classified, especially near their ancestral Pleistocene ranges in the Mojave and northern Sonoran deserts. The abundance of trees with both one- and two-needled fascicles in the zones between P. monophylla, P. edulis and fallax-type populations suggest that needle fascicle number is an unreliable characteristic for species classification. Disregarding needle fascicle number, the fallax-type needles are nearly identical to P. edulis, supporting Little's (1968) initial classification of these trees as P. edulis var. fallax, while the californiarum-type needles have a distinctive morphology supporting Bailey's (1987) classification of this tree as Pinus californiarum.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Biogeography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2699.2007.01786.x","issn":"03050270","usgsCitation":"Cole, K., Fisher, J., Arundel, S., Cannella, J., and Swift, S., 2008, Geographical and climatic limits of needle types of one- and two-needled pinyon pines: Journal of Biogeography, v. 35, no. 2, p. 257-269, https://doi.org/10.1111/j.1365-2699.2007.01786.x.","startPage":"257","endPage":"269","numberOfPages":"13","costCenters":[],"links":[{"id":476731,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2699.2007.01786.x","text":"Publisher Index Page"},{"id":241785,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214095,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2699.2007.01786.x"}],"volume":"35","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-09-24","publicationStatus":"PW","scienceBaseUri":"505a1790e4b0c8380cd5554c","contributors":{"authors":[{"text":"Cole, K.L.","contributorId":87507,"corporation":false,"usgs":true,"family":"Cole","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":441085,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fisher, J.","contributorId":37160,"corporation":false,"usgs":true,"family":"Fisher","given":"J.","affiliations":[],"preferred":false,"id":441081,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Arundel, S.T.","contributorId":77351,"corporation":false,"usgs":true,"family":"Arundel","given":"S.T.","email":"","affiliations":[],"preferred":false,"id":441082,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cannella, J.","contributorId":78563,"corporation":false,"usgs":true,"family":"Cannella","given":"J.","email":"","affiliations":[],"preferred":false,"id":441083,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Swift, S.","contributorId":80912,"corporation":false,"usgs":true,"family":"Swift","given":"S.","email":"","affiliations":[],"preferred":false,"id":441084,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70033140,"text":"70033140 - 2008 - Quasi-periodic bedding in the sedimentary rock record of mars","interactions":[],"lastModifiedDate":"2018-12-05T11:55:14","indexId":"70033140","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3338,"text":"Science","active":true,"publicationSubtype":{"id":10}},"title":"Quasi-periodic bedding in the sedimentary rock record of mars","docAbstract":"Widespread sedimentary rocks on Mars preserve evidence of surface conditions different from the modern cold and dry environment, although it is unknown how long conditions favorable to deposition persisted. We used 1-meter stereo topographic maps to demonstrate the presence of rhythmic bedding at several outcrops in the Arabia Terra region. Repeating beds are ∼10 meters thick, and one site contains hundreds of meters of strata bundled into larger units at a ∼10:1 thickness ratio. This repetition likely points to cyclicity in environmental conditions, possibly as a result of astronomical forcing. If deposition were forced by orbital variation, the rocks may have been deposited over tens of millions of years.
