The enantiomer fractions (EFs) measured in these samples are in good agreement with those reported for sediment, soil, and air samples in previous studies. The chlordane EFs were generally close to the racemic value of 0.5, with CC values ranging from 0.493 to 0.527 (usually &gt;0.5) and TC values from 0.463 to 0.53 (usually &lt;0.5). EF changes with core depth were detected for TC and CC in some cores, with the most non-racemic values near the top of the core. Surficial and suspended sediments generally have EF values similar to the top core layers but are often more non-racemic, indicating that enantioselective degradation is occurring before soils are eroded and deposited into bottom sediments. We hypothesize that rapid losses (desorption or degradation) from suspended sediments of the more bioavailable chlordane fraction during transport and initial deposition could explain the apparent shift to more racemic EF values in surficial and top core sediments. Near racemic CC and TC in the core profiles suggest minimal alteration of chlordane from biotic degradation, unless it is via non-enantioselective processes.

However, most EB models are complex to use and efforts are being made to simplify procedures mainly through the scaling of reference ET. The Simplified Surface Energy Balance (SSEB) is one such method. This approach has never been evaluated using measured ET data. In this study, the SSEB approach was applied to 14 Landsat TM images covering a major portion of the Southern High Plains that were acquired during 2006 and 2007 cropping seasons. Performance of the SSEB was evaluated by comparing estimated ET with measured daily ET from four large monolithic lysimeters at the USDA-ARS Conservation and Production Research Laboratory, Bushland, Texas. Statistical evaluation of results indicated that the SSEB accounted for 84% of the variability in the measured ET values with a slope and intercept of 0.75 and 1.1 mm d<sup>-1</sup>, respectively. Considering the minimal amount of ancillary data required and excellent performance in predicting daily ET, the SSEB approach is a promising tool for mapping ET in the semiarid Texas High Plains and in other parts of the world with similar hydro-climatic conditions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Engineering in Agriculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"08838542","usgsCitation":"Gowda, P., Senay, G., Howell, T., and Marek, T., 2009, Lysimetric evaluation of simplified surface energy balance approach in the Texas high plains: Applied Engineering in Agriculture, v. 25, no. 5, p. 665-669.","startPage":"665","endPage":"669","numberOfPages":"5","costCenters":[],"links":[{"id":245178,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4aa5e4b0c8380cd68f1a","contributors":{"authors":[{"text":"Gowda, P.H.","contributorId":63652,"corporation":false,"usgs":true,"family":"Gowda","given":"P.H.","email":"","affiliations":[],"preferred":false,"id":459505,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Senay, G.B. 0000-0002-8810-8539","orcid":"https://orcid.org/0000-0002-8810-8539","contributorId":17741,"corporation":false,"usgs":true,"family":"Senay","given":"G.B.","affiliations":[],"preferred":false,"id":459502,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Howell, T.A.","contributorId":57694,"corporation":false,"usgs":true,"family":"Howell","given":"T.A.","affiliations":[],"preferred":false,"id":459504,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Marek, T.H.","contributorId":38815,"corporation":false,"usgs":true,"family":"Marek","given":"T.H.","email":"","affiliations":[],"preferred":false,"id":459503,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The endocrine control of performance should be especially pronounced in animals that undergo a developmental shift in niche, such as occurs in migratory species. By way of example, I review the developmental and environmental control of the preparatory changes for seawater entry of juvenile salmon (known as smolting) and its hormonal regulation. There is a size threshold for smolt development in juvenile Atlantic salmon that results in greater sensitivity of the growth hormone and cortisol axes to changes in daylength. These hormones, in turn, have broad effects on survival, ion homeostasis, growth and swimming performance during entry into seawater. Migratory niche shifts and metamorphic events are extreme examples of the role of hormones in animal performance and represent one end of a continuum. A framework for predicting when hormones will be involved in performance of animals is presented. Endocrine involvement in performance will be more substantial when (1) selection differentials on traits underlying performance are high and temporally discontinuous over an animal's lifetime, (2) the energetic and fitness costs of maintaining performance plasticity are less than those of constant performance, (3) cues for altering performance are reliable indicators of critical environmental conditions, require neurosensory input, and minimize effects of lag, and (4) the need for coordination of organs, tissues and cells to achieve increased performance is greater. By examining these impacts of selection, endocrinologists have an opportunity to contribute to the understanding of performance, phenotypic plasticity, and the evolution of life-history traits.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Integrative and Comparative Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Oxford University Press","doi":"10.1093/icb/icp044","issn":"15407063","usgsCitation":"McCormick, S., 2009, Evolution of the hormonal control of animal performance: insights from the seaward migration of salmon: Integrative and Comparative Biology, v. 49, no. 4, p. 408-422, https://doi.org/10.1093/icb/icp044.","productDescription":"15 p.","startPage":"408","endPage":"422","costCenters":[{"id":197,"text":"Conte Anadromous Fish Research Center","active":false,"usgs":true}],"links":[{"id":476285,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/icb/icp044","text":"Publisher Index Page"},{"id":245305,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217361,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1093/icb/icp044"}],"volume":"49","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-06-16","publicationStatus":"PW","scienceBaseUri":"505a0d8be4b0c8380cd5309b","contributors":{"authors":[{"text":"McCormick, S.

The occurrence of concentrated gas hydrate at this site is primarily controlled by the presence of fractures. Assuming the resistivity of gas hydratebearing sediments is isotropic, th?? conventional Archie analysis using the logging while drilling resistivity log yields gas hydrate saturations greater than 50% (as high as ???80%) of the pore space for the depth interval between ???25 and ???160 m below seafloor. On the other hand, gas hydrate saturations estimated from pressure cores from nearby wells were less than ???26% of the pore space. Although intrasite variability may contribute to the difference, the primary cause of the saturation difference is attributed to the anisotropic nature of the reservoir due to gas hydrate in high-angle fractures. Archie's law can be used to estimate gas hydrate saturations in anisotropic reservoir, with additional information such as elastic velocities to constrain Archie cementation parameters m and the saturation exponent n. Theory indicates that m and n depend on the direction of the measurement relative to fracture orientation, as well as depending on gas hydrate saturation. By using higher values of m and n in the resistivity analysis for fractured reservoirs, the difference between saturation estimates is significantly reduced, although a sizable difference remains. To better understand the nature of fractured reservoirs, wireline P and S wave velocities were also incorporated into the analysis.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research B: Solid Earth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2008JB006237","issn":"01480227","usgsCitation":"Lee, M.W., and Collett, T.S., 2009, Gas hydrate saturations estimated from fractured reservoir at Site NGHP-01-10, Krishna-Godavari Basin, India: Journal of Geophysical Research B: Solid Earth, v. 114, no. 7, https://doi.org/10.1029/2008JB006237.","costCenters":[],"links":[{"id":245716,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217752,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2008JB006237"}],"volume":"114","issue":"7","noUsgsAuthors":false,"publicationDate":"2009-07-16","publicationStatus":"PW","scienceBaseUri":"505a14d0e4b0c8380cd54b9e","contributors":{"authors":[{"text":"Lee, Myung W.","contributorId":84358,"corporation":false,"usgs":true,"family":"Lee","given":"Myung","middleInitial":"W.","affiliations":[],"preferred":false,"id":458818,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Collett, T.

Biogenic macroporosity largely manifests as: (1) ichnogenic macroporosity primarily related to postdepositional burrowing activity by callianassid shrimp and fossilization of components of their complex burrow systems (Ophiomorpha); and (2) biomoldic macroporosity originating from dissolution of fossil hard parts, principally mollusk shells. Ophiomorpha-dominated ichno-fabric provides the greatest contribution to hydrologic characteristics in the Biscayne aquifer in a 345 km<sup>2</sup> study area. Stratiform tabular-shaped units of thalassinidean-associated macroporosity are commonly confined to the lower part of upward-shallowing high-frequency cycles, throughout aggradational cycles, and, in one case, they stack vertically within the lower part of a high-frequency cycle set. Broad continuity of many of the macroporous units concentrates groundwater flow in extremely permeable passage-ways, thus making the aquifer vulnerable to long-distance transport of contaminants. Ichnogenic macroporosity represents an alternative pathway for concentrated groundwater flow that differs considerably from standard karst flow-system paradigms, which describe groundwater movement through fractures and cavernous dissolution features. Permeabilities were calculated using lattice Boltzmann methods (LBMs) applied to computer renderings assembled from X-ray computed tomography scans of various biogenic macroporous limestone samples. The highest simulated LBM permeabilities were about five orders of magnitude greater than standard laboratory measurements using air-permeability methods, which are limited in their application to extremely permeable macroporous rock samples. Based on their close conformance to analytical solutions for pipe flow, LBMs offer a new means of obtaining accurate permeability values for such materials. We suggest that the stratiform ichnogenic groundwater flow zones have permeabilities even more extreme (???2-5 orders of magnitude higher) than the Jurassic \"super-K\" zones of the giant Ghawar oil field. The flow zones of the Pleistocene Biscayne aquifer provide examples of ichnogenic macroporosity for comparative analysis of origin and evolution in other carbonate aquifers, as well as petroleum reservoirs. ?? 2008 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geological Society of America Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/B26392.1","issn":"00167606","usgsCitation":"Cunningham, K., Sukop, M., Huang, H., Alvarez, P., Curran, H., Renken, R., and Dixon, J., 2009, Prominence of ichnologically influenced macroporosity in the karst Biscayne aquifer: Stratiform \"super-K\" zones: Geological Society of America Bulletin, v. 121, no. 1-2, p. 164-180, https://doi.org/10.1130/B26392.1.","startPage":"164","endPage":"180","numberOfPages":"17","costCenters":[],"links":[{"id":217695,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/B26392.1"},{"id":245655,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"121","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8f04e4b0c8380cd7f524","contributors":{"authors":[{"text":"Cunningham, K.J.","contributorId":39852,"corporation":false,"usgs":true,"family":"Cunningham","given":"K.J.","email":"","affiliations":[],"preferred":false,"id":458803,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sukop, M.C.","contributorId":88468,"corporation":false,"usgs":true,"family":"Sukop","given":"M.C.","affiliations":[],"preferred":false,"id":458805,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Huang, H.","contributorId":18571,"corporation":false,"usgs":true,"family":"Huang","given":"H.","email":"","affiliations":[],"preferred":false,"id":458801,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Alvarez, P.F.","contributorId":105566,"corporation":false,"usgs":true,"family":"Alvarez","given":"P.F.","email":"","affiliations":[],"preferred":false,"id":458807,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Curran, H.A.","contributorId":30820,"corporation":false,"usgs":true,"family":"Curran","given":"H.A.","email":"","affiliations":[],"preferred":false,"id":458802,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Renken, R.A.","contributorId":99161,"corporation":false,"usgs":true,"family":"Renken","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":458806,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Dixon, J.F.","contributorId":52435,"corporation":false,"usgs":true,"family":"Dixon","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":458804,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Over 1300 archival soil samples collected from the late 1970s to 1980 in El Dorado, Placer, Sutter, Sacramento, Yolo and Solano counties were analyzed for 42 elements by inductively coupled plasma-atomic emission spectrometry and inductively coupled plasma-mass spectrometry following a near-total dissolution. These data were supplemented by analysis of more than 500 stream-sediment samples from higher elevations in the Sierra Nevada from the same study site. The relatively high-density data (1 sample per 15 km<sup>2</sup> for much of the study area) allows the delineation of regional geochemical patterns and the identification of processes that produced these patterns. The geochemical results segregate broadly into distinct element groupings whose distribution reflects the interplay of geologic, hydrologic, geomorphic and anthropogenic factors. One such group includes elements associated with mafic and ultramafic rocks including Cr, Ni, V, Co, Cu and Mg. Using Cr as an example, elevated concentrations occur in soils overlying ultramafic rocks in the foothills of the Sierra Nevada (median Cr = 160 mg/kg) as well as in the northern Coast Ranges. Low concentrations of these elements occur in soils located further upslope in the Sierra Nevada overlying Tertiary volcanic, metasedimentary and plutonic rocks (granodiorite and diorite). Eastern Sacramento Valley soil samples, defined as those located east of the Sacramento River, are lower in Cr (median Cr = 84 mg/kg), and are systematically lower in this suite compared to soils from the west side of the Sacramento Valley (median Cr = 130 mg/kg). A second group of elements showing a coherent pattern, including Ca, K, Sr and REE, is derived from relatively silicic rocks types. This group occurs at elevated concentrations in soils overlying volcanic and plutonic rocks at higher elevations in the Sierras (e.g. median La = 28 mg/kg) and the east side of the Sacramento Valley (median 20 mg/kg) compared to soils overlying ultramafic rocks in the Sierra Nevada foothills (median 15 mg/kg) and the western Sacramento Valley (median 14 mg/kg). The segregation of soil geochemistry into distinctive groupings across the Sacramento River arises from the former presence of a natural levee (now replaced by an artificial one) along the banks of the river. This levee has been a barrier to sediment transport. Sediment transport to the Valley by glacial outwash from higher elevations in the Sierra Nevada and, more recently, debris from placer Au mining has dominated sediment transport to the eastern Valley. High content of mafic elements (and low content of silicic elements) in surface soil in the west side of the valley is due to a combination of lack of silicic source rocks, transport of ultramafic rock material from the Coast Ranges, and input of sediment from the late Mesozoic Great Valley Group, which is itself enriched in mafic elements. A third group of elements (Zn, Cd, As and Cu) reflect the impact of mining activity. Soil with elevated content of these elements occurs along the Sacramento River in both levee and adjacent flood basin settings. It is interpreted that transport of sediment down the Sacramento River from massive sulfide mines in the Klamath Mountains to the north has caused this pattern. The Pb, and to some extent Zn, distribution patterns are strongly impacted by anthropogenic inputs. Elevated Pb content is localized in major cites and along major highways due to inputs from leaded gasoline. Zinc has a similar distribution pattern but the source is tire wear.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2009.04.018","issn":"08832927","usgsCitation":"Goldhaber, M., Morrison, J., Holloway, J., Wanty, R., Helsel, D., and Smith, D.B., 2009, A regional soil and sediment geochemical study in northern California: Applied Geochemistry, v. 24, no. 8, p. 1482-1499, https://doi.org/10.1016/j.apgeochem.2009.04.018.","startPage":"1482","endPage":"1499","numberOfPages":"18","costCenters":[],"links":[{"id":217605,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2009.04.018"},{"id":245561,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e543e4b0c8380cd46c47","contributors":{"authors":[{"text":"Goldhaber, M.

However, analyses to determine involvement of wild birds have been hindered by the lack of basic information on their movements in central Asia. Thus, we initiated a programme to document migrations of waterfowl in Asian flyways to inform hypotheses of H5N1 transmission. As part of this work, we studied migration of waterfowl from Qinghai Lake, China, site of the 2005 H5N1 outbreak in wild birds. We examined the null hypothesis that no direct migratory connection existed between Qinghai Lake and H5N1 outbreak areas in central Mongolia, as suggested by some H5N1 phylogeny studies. We captured individuals in 2007 from two of the species that died in the Qinghai Lake outbreaks and marked them with GPS satellite transmitters: Bar-headed Geese Anser indicus (n = 14) and Ruddy Shelduck Tadorna ferruginea (n = 11). Three of 25 marked birds (one Goose and two Shelducks) migrated to breeding grounds near H5N1 outbreak areas in Mongolia. Our results describe a previously unknown migratory link between the two regions and offer new critical information on migratory movements in the region. ?? 2009 British Ornithologists' Union.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ibis","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1474-919X.2009.00932.x","issn":"00191019","usgsCitation":"Prosser, D., Takekawa, J.Y., Newman, S.H., Yan, B., Douglas, D., Hou, Y., Xing, Z., Zhang, D., Li, T., Li, Y., Zhao, D., Perry, W., and Palm, E., 2009, Satellite-marked waterfowl reveal migratory connection between H5N1 outbreak areas in China and Mongolia: Ibis, v. 151, no. 3, p. 568-576, https://doi.org/10.1111/j.1474-919X.2009.00932.x.","startPage":"568","endPage":"576","numberOfPages":"9","costCenters":[],"links":[{"id":245712,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217748,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1474-919X.2009.00932.x"}],"volume":"151","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-06-24","publicationStatus":"PW","scienceBaseUri":"505b86f3e4b08c986b316209","contributors":{"authors":[{"text":"Prosser, D.J. 0000-0002-5251-1799","orcid":"https://orcid.org/0000-0002-5251-1799","contributorId":65185,"corporation":false,"usgs":true,"family":"Prosser","given":"D.J.","affiliations":[],"preferred":false,"id":458358,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":458357,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Newman, S.

Compared with chicks reared by non-handled adults that did not carry tags, deployment of tags on one or both adult parents ultimately resulted in 35% reduction in chick body mass and significantly reduced chick skeletal size preceding fledging (19 April). However, body mass between chick groups was not significantly different after controlling for skeletal size. Effects on chicks were more pronounced in six pairs where both parents carried tags. Chick mass was negatively related to the duration that adults carried tags. In this study, none of the chicks reared by pairs where both parents were tagged, 54% of chicks reared by pairs where one parent was tagged, and 83% of chicks reared by non-handled and non-tagged parents achieved a previously determined pre-fledging mass threshold (564 g; Sagar & Horning 1998). Body mass of adults carrying tags and returning from transequatorial migration the following year were 4% lighter on average than non-tagged birds, but this difference was not statistically significant. Reduced mass among chicks reared by adults carrying tags during the chick-provisioning period indicated that adults altered \"normal\" provisioning behaviours to maintain their own body condition at the expense of their chicks. Population-level information derived from telemetry studies can reveal important habitat-linked behaviours, unique aspects of seabird foraging behaviours, and migration ecology. Information for some species (e.g., overlap with fisheries) can aid conservation and marine ecosystem management. We advise caution, however, when interpreting certain data related to adult provisioning behaviours (e.g., time spent foraging, provisioning rates, etc.). If effects on individuals are of concern, we suggest shorter-term deployments, smaller and lighter tags, and alternative attachment techniques, especially when investigating threatened or endangered species. ??

Our study has revealed the vestiges of thin basaltic tephra deposits, overlooked by previous workers, that originally blanketed wide, near-summit areas and extended more than 17 km to the south coast of Hawai‘i. These deposits, correlative with parts of tephra units at the summit and at sites farther north and northwest, show that Kīlauea, commonly regarded as a gentle volcano, was the site of energetic pyroclastic eruptions and indicate the volcano is significantly more hazardous than previously realized. Seventeen new calibrated accelerator mass spectrometry (AMS) radiocarbon ages suggest these deposits, here named the Kulanaokuaiki Tephra, were emplaced ca. A.D. 400–1000, a time of no previously known pyroclastic activity at the volcano. Tephra correlations are based chiefly on a marker unit that contains unusually high values of TiO</span><sub>2</sub><span>&nbsp;and K</span><sub>2</sub><span>O and on paleomagnetic signatures of associated lava flows, which show that the Kulanaokuaiki deposits are the time-stratigraphic equivalent of the upper part of a newly exhumed section of the Uwēkahuna Ash in the volcano's northwest caldera wall. This section, thought to have been permanently buried by rockfalls in 1983, is thicker and more complete than the previously accepted type Uwēkahuna at the base of the caldera wall. Collectively, these findings justify the elevation of the Uwēkahuna Ash to formation status; the newly recognized Kulanaokuaiki Tephra to the south, the chief focus of this study, is defined as a member of the Uwēkahuna Ash. The Kulanaokuaiki Tephra is the product of energetic pyroclastic falls; no surge- or pyroclastic-flow deposits were identified with certainty, despite recent interpretations that Uwēkahuna surges extended 10–20 km from Kīlauea's summit.</span> 2009 Geological Society of America.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geological Society of America Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/B26327.1","issn":"00167606","usgsCitation":"Fiske, R., Rose, T., Swanson, D.A., Champion, D., and McGeehin, J., 2009, Kulanaokuaiki Tephra (ca, A.D. 400-1000): Newly recognized evidence for highly explosive eruptions at Kilauea Volcano, Hawai'i: Geological Society of America Bulletin, v. 121, no. 5-6, p. 712-728, https://doi.org/10.1130/B26327.1.","productDescription":"17 p.","startPage":"712","endPage":"728","numberOfPages":"17","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":217515,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/B26327.1"},{"id":245466,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawai'i","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -155.37139892578125,\n              19.287165134039128\n            ],\n            [\n              -155.08163452148438,\n              19.287165134039128\n            ],\n            [\n              -155.08163452148438,\n              19.444579339485816\n            ],\n            [\n              -155.37139892578125,\n              19.444579339485816\n            ],\n            [\n              -155.37139892578125,\n              19.287165134039128\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"121","issue":"5-6","noUsgsAuthors":false,"publicationDate":"2009-04-27","publicationStatus":"PW","scienceBaseUri":"505a40cce4b0c8380cd6504d","contributors":{"authors":[{"text":"Fiske, R.S.","contributorId":47783,"corporation":false,"usgs":true,"family":"Fiske","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":458125,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rose, T.R.","contributorId":86569,"corporation":false,"usgs":true,"family":"Rose","given":"T.R.","email":"","affiliations":[],"preferred":false,"id":458128,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Swanson, D.

The broadband synthetics were constructed for earthquakes of M 5.5, 6.5, and 7.5 by combining deterministic synthetics for plane-layered models at low frequencies with stochastic synthetics at high frequencies. The stochastic portion used a source model where the Brune stress drop of 100 bars is constant with seismic moment. The deterministic synthetics were calculated using an average slip velocity, and hence, dynamic stress drop, on the fault that is uniform with magnitude. One novel aspect of this procedure is that the transition frequency between the deterministic and stochastic portions varied with magnitude, so that the transition frequency is inversely related to the rise time of slip on the fault. The spectral accelerations at 0.2, 1.0, and 3.0 sec periods from the synthetics generally agreed with those from the set of NGA relations for M 5.5-7.5 for distances of 2-100 km. At distances of 100-200 km some of the NGA relations for 0.2 sec spectral acceleration were substantially larger than the values of the synthetics for M 7.5 and M 6.5 earthquakes because these relations do not have a term accounting for Q. At 3 and 5 sec periods, the synthetics for M 7.5 earthquakes generally had larger spectral accelerations than the NGA relations, although there was large scatter in the results from the synthetics. The synthetics showed a sag in response spectra at close-in distances for M 5.5 between 0.3 and 0.7 sec that is not predicted from the NGA relations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120080079","issn":"00371106","usgsCitation":"Frankel, A., 2009, A constant stress-drop model for producing broadband synthetic seismograms: Comparison with the next generation attenuation relations: Bulletin of the Seismological Society of America, v. 99, no. 2 A, p. 664-680, https://doi.org/10.1785/0120080079.","startPage":"664","endPage":"680","numberOfPages":"17","costCenters":[],"links":[{"id":217459,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120080079"},{"id":245409,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"2 A","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e396e4b0c8380cd46100","contributors":{"authors":[{"text":"Frankel, A. 0000-0001-9119-6106","orcid":"https://orcid.org/0000-0001-9119-6106","contributorId":41593,"corporation":false,"usgs":true,"family":"Frankel","given":"A.","affiliations":[],"preferred":false,"id":458117,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This fault has no historical seismicity for large earthquakes, although it may have generated moderate (M5+) earthquakes in 1751 and 1858. Evidence of continued left horizontal displacement is shown by the presence of Cenozoic pull-apart basins as well as late Quaternary stream deflections. To investigate its recent slip history, a number of trenches were excavated at three sites along the Vilari&ccedil;a segment, north and south of the Douro River. At one site at Vale Me&atilde;o winery, the occurrence of at least two and probably three events in the past 14.5 ka was determined, suggesting an average return period of about 5&ndash;7 ka. All three events appear to have occurred as a cluster in the interval between 14.5 and 11 ka, or shortly thereafter, suggesting a return period of less than 2 ka between events within the cluster. In the same area, a small offset rill suggests 2&ndash;2.5 m of slip in the most recent event and about 6.1 m after incision below a&nbsp;</span><i>c</i><span>. 16 ka alluvial fill event along the Douro River. At another site along the Vilari&ccedil;a River alluvial plain, NE of the Vale Me&atilde;o site, several trenches were excavated in late Pleistocene and Holocene alluvium, and exposed the fault displacing channel deposits dated to between 18 and 23 ka. In a succession of closely spaced parallel cuts and trenches, the channel riser was traced into and across the fault to resolve&nbsp;</span><i>c</i><span>. 6.5 m of displacement after 18 ka and&nbsp;</span><i>c</i><span>. 9 m of slip after&nbsp;</span><i>c</i><span>. 23 ka. These observations yield a slip rate of 0.3&ndash;0.5 mm/a, which is consistent with earlier estimates. Combining the information on timing at Vale Me&atilde;o winery and displacement at Vilari&ccedil;a argues for earthquakes in the M7+ range, with coseismic displacements of 2&ndash;3 m. This demonstrates that there are potential seismic sources in Portugal that are not associated with the 1755 Lisbon earthquake or the Tagus Valley, and, although rare, large events on the Vilari&ccedil;a fault could be quite destructive for the region. This work provides an analogue for the study of active faulting in intracontinental settings and supports the view that earthquakes within intracontinental settings tend to cluster in time. In addition, this study highlights the usefulness and application of multiple field, remote sensing and geochronological techniques for seismic hazard mitigation.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1144/SP316.15","issn":"03058719","usgsCitation":"Rockwell, T., Fonseca, J., Madden, C., Dawson, T., Owen, L., Vilanova, S., and Figueiredo, P., 2009, Palaeoseismology of the Vilariça segment of the Manteigas-Bragança fault in northeastern Portugal: Special Paper of the Geological Society of America, no. 316, p. 237-258, https://doi.org/10.1144/SP316.15.","productDescription":"22 p.","startPage":"237","endPage":"258","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":245708,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217745,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1144/SP316.15"}],"country":"Portugal","otherGeospatial":"Manteigas - Braganca fault","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -7.679443359375,\n              40.9052096972736\n            ],\n            [\n              -7.679443359375,\n              41.73852846935917\n            ],\n            [\n              -6.767578125,\n              41.73852846935917\n            ],\n            [\n              -6.767578125,\n              40.9052096972736\n            ],\n            [\n              -7.679443359375,\n              40.9052096972736\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","issue":"316","noUsgsAuthors":false,"publicationDate":"2009-06-17","publicationStatus":"PW","scienceBaseUri":"505a73ace4b0c8380cd771a5","contributors":{"authors":[{"text":"Rockwell, Thomas","contributorId":58810,"corporation":false,"usgs":true,"family":"Rockwell","given":"Thomas","affiliations":[],"preferred":false,"id":458068,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fonseca, Joao","contributorId":7945,"corporation":false,"usgs":true,"family":"Fonseca","given":"Joao","email":"","affiliations":[],"preferred":false,"id":458064,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Madden, Chris","contributorId":102719,"corporation":false,"usgs":true,"family":"Madden","given":"Chris","email":"","affiliations":[],"preferred":false,"id":458070,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dawson, Tim","contributorId":50692,"corporation":false,"usgs":true,"family":"Dawson","given":"Tim","email":"","affiliations":[],"preferred":false,"id":458067,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Owen, Lewis A.","contributorId":138784,"corporation":false,"usgs":false,"family":"Owen","given":"Lewis A.","affiliations":[{"id":6694,"text":"Department of Marine, Earth and Atmospheric Sciences, North Carolina State University, Raleigh, North Carolina","active":true,"usgs":false}],"preferred":false,"id":458069,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Vilanova, Susana","contributorId":8316,"corporation":false,"usgs":true,"family":"Vilanova","given":"Susana","email":"","affiliations":[],"preferred":false,"id":458065,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Figueiredo, Paula","contributorId":44394,"corporation":false,"usgs":true,"family":"Figueiredo","given":"Paula","email":"","affiliations":[],"preferred":false,"id":458066,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

The ASRVN is an operational data collection and processing system. It receives 50 ?? 50 km<sup>2</sup>; subsets of MODIS level 1B (L1B) data from MODIS adaptive processing system and AERONET aerosol and water-vapor information. Then, it performs an atmospheric correction (AC) for about 100 AERONET sites based on accurate radiative-transfer theory with complex quality control of the input data. The ASRVN processing software consists of an L1B data gridding algorithm, a new cloud-mask (CM) algorithm based on a time-series analysis, and an AC algorithm using ancillary AERONET aerosol and water-vapor data. The AC is achieved by fitting the MODIS top-of-atmosphere measurements, accumulated for a 16-day interval, with theoretical reflectance parameterized in terms of the coefficients of the Li SparseRoss Thick (LSRT) model of the bidirectional reflectance factor (BRF). The ASRVN takes several steps to ensure high quality of results: 1) the filtering of opaque clouds by a CM algorithm; 2) the development of an aerosol filter to filter residual semitransparent and subpixel clouds, as well as cases with high inhomogeneity of aerosols in the processing area; 3) imposing the requirement of the consistency of the new solution with previously retrieved BRF and albedo; 4) rapid adjustment of the 16-day retrieval to the surface changes using the last day of measurements; and 5) development of a seasonal backup spectral BRF database to increase data coverage. The ASRVN provides a gapless or near-gapless coverage for the processing area. The gaps, caused by clouds, are filled most naturally with the latest solution for a given pixel. The ASRVN products include three parameters of the LSRT model (kL, kG, and kV), surface albedo, normalized BRF (computed for a standard viewing geometry, VZA = 0, SZA = 45??), and instantaneous BRF (or one-angle BRF value derived from the last day of MODIS measurement for specific viewing geometry) for the MODIS 500-m bands 17. The results are produced daily at a resolution of 1 km in gridded format. We also provide a cloud mask, a quality flag, and a browse bitmap image. The ASRVN data set, including 6 years of MODIS TERRA and 1.5 years of MODIS AQUA data, is available now as a standard MODIS product (MODASRVN) which can be accessed through the Level 1 and Atmosphere Archive and Distribution System website ( http://ladsweb.nascom.nasa.gov/data/search.html). It can be used for a wide range of applications including validation analysis and science research. ?? 2006 IEEE.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"IEEE Transactions on Geoscience and Remote Sensing","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1109/TGRS.2009.2016334","issn":"01962892","usgsCitation":"Wang, Y., Lyapustin, A., Privette, J., Morisette, J., and Holben, B., 2009, Atmospheric correction at AERONET locations: A new science and validation data set: IEEE Transactions on Geoscience and Remote Sensing, v. 47, no. 8, p. 2450-2466, https://doi.org/10.1109/TGRS.2009.2016334.","startPage":"2450","endPage":"2466","numberOfPages":"17","costCenters":[],"links":[{"id":217685,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/TGRS.2009.2016334"},{"id":245645,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"47","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eebfe4b0c8380cd49f10","contributors":{"authors":[{"text":"Wang, Y.","contributorId":64213,"corporation":false,"usgs":true,"family":"Wang","given":"Y.","affiliations":[],"preferred":false,"id":458050,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lyapustin, A.I.","contributorId":40452,"corporation":false,"usgs":true,"family":"Lyapustin","given":"A.I.","email":"","affiliations":[],"preferred":false,"id":458048,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Privette, J.L.","contributorId":67759,"corporation":false,"usgs":true,"family":"Privette","given":"J.L.","affiliations":[],"preferred":false,"id":458051,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Morisette, J.T.","contributorId":57029,"corporation":false,"usgs":true,"family":"Morisette","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":458049,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Holben, B.","contributorId":75762,"corporation":false,"usgs":true,"family":"Holben","given":"B.","affiliations":[],"preferred":false,"id":458052,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

This work was intended to answer the following two questions unresolved in previous studies: (1) Was there only one source of water (Mangala Fossa at the valley head which is one of the Medusae Fossae troughs or graben) or were other sources also involved in the valley-carving water supply, and (2) Was there only one episode of flooding (maybe with phases) or were there several episodes significantly separated in time. The geologic analysis of HRSC image 0286 and mapping supported by analysis of MOC and THEMIS images show that Mangala Valles was carved by water released from several sources. The major source was Mangala Fossa, which probably formed in response to magmatic dike intrusion. The graben cracked the cryosphere and permitted the release of groundwater held under hydrostatic pressure. This major source was augmented by a few smaller-scale sources at localities in (1) two mapped heads of magmatic dikes, (2) heads of two clusters of sinuous channels, and (3) probably several large knob terrain locals. The analysis of results of crater counts at more than 60 localities showed that the first episode of formation of Mangala Valles occurred ???3.5 Ga ago and was followed by three more episodes, one occurred ???1 Ga ago, another one ???0.5 Ga ago, and the last one ???0.2 Ga ago. East of the mapped area there are extended and thick lava flows whose source may be the eastern continuation of the Mangala source graben. Crater counts in 10 localities on these lava flows correlate with those taken on the Mangala valley elements supporting the idea that the valley head graben was caused by dike intrusions. Our observations suggest that the waning stage of the latest flooding episode (???0.2 Ga ago) led to the formation at the valley head of meander-like features sharing some characteristics with meanders of terrestrial rivers. If this analogy is correct this could suggest a short episode of global warming in Late Amazonian time. ?? 2008 Elsevier Ltd.

MLEE and AFLP revealed considerable genetic variability among B. bassiana isolates. Several isolates from South and Southeast Brazil had high similarity coefficients, providing evidence of at least one population with clonal structure. There were clear genomic differences between most Brazilian and USA B. bassiana isolates. A Mantel test using data generated by AFLP provided evidence that greater geographical distances were associated with higher genetic distances. AFLP and rDNA sequencing demonstrated notable genotypic variation between B. bassiana and other Beauveria spp. Conclusion: Geographical distance between populations apparently is an important factor influencing genotypic variability among B. bassiana populations in Brazil. Significance and Impact of the Study: This study characterized many B. bassiana isolates. The results indicate that certain Brazilian isolates are considerably different from others and possibly should be regarded as separate species from B. bassiana sensu latu. The information on genetic variation among the Brazilian isolates, therefore, will be important to comprehending the population structure of B. bassiana in Brazil. ?? 2009 The Society for Applied Microbiology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Microbiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2672.2009.04258.x","issn":"13645072","usgsCitation":"Fernandes, E., Moraes, A., Pacheco, R., Rangel, D., Miller, M., Bittencourt, V., and Roberts, D., 2009, Genetic diversity among brazilian isolates of beauveria bassiana: comparisons with non-brazilian isolates and other beauveria species: Journal of Applied Microbiology, v. 107, no. 3, p. 760-774, https://doi.org/10.1111/j.1365-2672.2009.04258.x.","startPage":"760","endPage":"774","numberOfPages":"15","costCenters":[],"links":[{"id":476137,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://www.arca.fiocruz.br/handle/icict/28133","text":"Publisher Index Page"},{"id":217852,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2672.2009.04258.x"},{"id":245824,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"107","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1571e4b0c8380cd54dfa","contributors":{"authors":[{"text":"Fernandes, E.K.K.","contributorId":87384,"corporation":false,"usgs":true,"family":"Fernandes","given":"E.K.K.","email":"","affiliations":[],"preferred":false,"id":457672,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moraes, A.M.L.","contributorId":17077,"corporation":false,"usgs":true,"family":"Moraes","given":"A.M.L.","email":"","affiliations":[],"preferred":false,"id":457668,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pacheco, R.S.","contributorId":39221,"corporation":false,"usgs":true,"family":"Pacheco","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":457670,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rangel, D.E.N.","contributorId":32362,"corporation":false,"usgs":true,"family":"Rangel","given":"D.E.N.","email":"","affiliations":[],"preferred":false,"id":457669,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Miller, M.P.","contributorId":47142,"corporation":false,"usgs":true,"family":"Miller","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":457671,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bittencourt, V.R.E.P.","contributorId":91342,"corporation":false,"usgs":true,"family":"Bittencourt","given":"V.R.E.P.","email":"","affiliations":[],"preferred":false,"id":457673,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Roberts, D.W.","contributorId":11828,"corporation":false,"usgs":true,"family":"Roberts","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":457667,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

To test this hypothesis, we sampled at 0.2 m increments a basal till from one advance of the lobe (Batestown till) along vertical profiles and measured fabrics due to both anisotropy of magnetic susceptibility and sand-grain preferred orientation. Unlike past fabric studies, interpretations were guided by results of laboratory experiments in which this till was deformed in simple shear to high strains. Fabric strengths indicate that more than half of the till sampled has a <5% probability of having been sheared to moderate strains (7-30). Secular changes in fabric azimuth over the thickness of the till, probably due to changing ice-flow direction as the lobe receded, indicate that the bed accreted with time and that the depth of deformation of the bed did not exceed a few decimeters. Orientations of principal magnetic susceptibilities show that the state of strain was commonly complex, deviating from bed-parallel simple shear. Deformation is inferred to have been focused in shallow, temporally variable patches during till deposition from ice.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Glaciology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.3189/002214309788608877","issn":"00221430","usgsCitation":"Thomason, J., and Iverson, N., 2009, Deformation of the Batestown till of the Lake Michigan lobe, Laurentide ice sheet: Journal of Glaciology, v. 55, no. 189, p. 131-146, https://doi.org/10.3189/002214309788608877.","startPage":"131","endPage":"146","numberOfPages":"16","costCenters":[],"links":[{"id":476442,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3189/002214309788608877","text":"Publisher Index Page"},{"id":217733,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3189/002214309788608877"},{"id":245695,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"55","issue":"189","noUsgsAuthors":false,"publicationDate":"2017-09-08","publicationStatus":"PW","scienceBaseUri":"5059fe4be4b0c8380cd4ec4f","contributors":{"authors":[{"text":"Thomason, J.F.","contributorId":11745,"corporation":false,"usgs":true,"family":"Thomason","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":457033,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Iverson, N.R.","contributorId":19682,"corporation":false,"usgs":true,"family":"Iverson","given":"N.R.","email":"","affiliations":[],"preferred":false,"id":457034,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Erythrina are favored ornamental and landscape trees, as well as native members of threatened ecosystems. The EGW is a tiny, highly mobile, highly invasive wasp that deforms (galls) host trees causing severe defoliation and tree death. The first detection of EGW in the United States was in O'ahu, Hawai'i in April 2005. It quickly spread through the Hawai'ian island chain (U.S.) killing ornamental and native Erythrina in as little as two years. At risk are endemic populations of Erythrinaas well as ornamental landscape species in the same genus, the latter of which have already been killed and removed from O'ahu at a cost of more than USD $1 million. Because EGW are so small and spread so quickly, host injury is usually detected before adult wasps are observed, making prophylactic treatments less likely than therapeutic ones. This study evaluates two stem-injected insecticides, imidacloprid (IMA-jet??) and emamectin benzoate, delivered through Arborjet Tree I.V.?? equipment, for their ability to affect E. sandwicensis (wiliwili) canopy demise under severe EGW exposure. IMA-jet, applied at a rate of 0.16 g AI/cm basal diameter (0.4 g AI/in. dia.), was the only effective treatment for maintaining canopy condition of wiliwili trees. Emamectin benzoate, applied at a rate of -0.1 g AI/cm basal diameter (-0.25 g AI/in. dia.), was not effective in this application, although it was intermediate in effect between IMA-jet and untreated trees. The relatively high concentrations of imidacloprid in leaves, and its durability for at least 13 months in native wiliwili growing on a natural, dryland site, suggest that treatment applications against EGW can impact canopy recovery even under suboptimal site and tree conditions. ?? 2009 International Society of Arboriculture.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Arboriculture and Urban Forestry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"02785226","usgsCitation":"Doccola, J., Smith, S., Strom, B., Medeiros, A., and Von Allmen, E., 2009, Systemically applied insecticides for treatment of erythrina gall wasp, quadrastichus erythrinae kim hymenoptera: Eulophidae: Arboriculture and Urban Forestry, v. 35, no. 4, p. 173-181.","startPage":"173","endPage":"181","numberOfPages":"9","costCenters":[],"links":[{"id":245628,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba376e4b08c986b31fcf0","contributors":{"authors":[{"text":"Doccola, J.J.","contributorId":72625,"corporation":false,"usgs":true,"family":"Doccola","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":456872,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, S.L.","contributorId":99277,"corporation":false,"usgs":true,"family":"Smith","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":456873,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Strom, B.L.","contributorId":68568,"corporation":false,"usgs":true,"family":"Strom","given":"B.L.","email":"","affiliations":[],"preferred":false,"id":456871,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Medeiros, A.C.","contributorId":19703,"corporation":false,"usgs":true,"family":"Medeiros","given":"A.C.","email":"","affiliations":[],"preferred":false,"id":456869,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Von Allmen, E.","contributorId":25692,"corporation":false,"usgs":true,"family":"Von Allmen","given":"E.","affiliations":[],"preferred":false,"id":456870,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

This model comprises a time-independent (Poisson-process) earthquake rate model, developed jointly with the National Seismic Hazard Mapping Program and a time-dependent earthquake-probability model, based on recent earthquake rates and stress-renewal statistics conditioned on the date of last event. The models were developed from updated statewide earthquake catalogs and fault deformation databases using a uniform methodology across all regions and implemented in the modular, extensible Open Seismic Hazard Analysis framework. The rate model satisfies integrating measures of deformation across the plate-boundary zone and is consistent with historical seismicity data. An overprediction of earthquake rates found at intermediate magnitudes (6.5 ??? M ???7.0) in previous models has been reduced to within the 95% confidence bounds of the historical earthquake catalog. A logic tree with 480 branches represents the epistemic uncertainties of the full time-dependent model. The mean UCERF 2 time-dependent probability of one or more M ???6.7 earthquakes in the California region during the next 30 yr is 99.7%; this probability decreases to 46% for M ???7.5 and to 4.5% for M ???8.0. These probabilities do not include the Cascadia subduction zone, largely north of California, for which the estimated 30 yr, M ???8.0 time-dependent probability is 10%. The M ???6.7 probabilities on major strike-slip faults are consistent with the WGCEP (2003) study in the San Francisco Bay Area and the WGCEP (1995) study in southern California, except for significantly lower estimates along the San Jacinto and Elsinore faults, owing to provisions for larger multisegment ruptures.

The UK-DMC Surrey Linear Imager 6 (SLIM-6) sensor has a 32-m spatial resolution and a ground swath width of 640 km. The UK-DMC SLIM-6 design consists of a three-band imager with green, red, and near-infrared bands that are set to similar bandpass as Landsat bands 2, 3, and 4. The UK-DMC data consisted of imagery registered to Landsat orthorectified imagery produced from the GeoCover program. Relief displacements within the UK-DMC SLIM-6 imagery were accounted for by using global 1-km digital elevation models available through the Global Land One-km Base Elevation (GLOBE) Project. Positional accuracy and relative band-to-band accuracy were measured. Positional accuracy of the UK-DMC SLIM-6 imagery was assessed by measuring the imagery against digital orthophoto quadrangles (DOQs), which are designed to meet national map accuracy standards at 1 : 24 000 scales; this corresponds to a horizontal root-mean-square accuracy of about 6 m. The UK-DMC SLIM-6 images were typically registered to within 1.0-1.5 pixels to the DOQ mosaic images. Several radiometric artifacts like striping, coherent noise, and flat detector were discovered and studied. Indications are that the SSTL UK-DMC SLIM-6 data have few artifacts and calibration challenges, and these can be adjusted or corrected via calibration and processing algorithms. The cross-calibration of the UK-DMC SLIM-6 and Landsat 7 Enhanced Thematic Mapper Plus was performed using image statistics derived from large common areas observed by the two sensors.</span></p>","language":"English","publisher":"IEEE","doi":"10.1109/TGRS.2009.2013206","issn":"01962892","usgsCitation":"Chander, G., Saunier, S., Choate, M., and Scaramuzza, P.L., 2009, SSTL UK-DMC SLIM-6 data quality assessment: IEEE Transactions on Geoscience and Remote Sensing, v. 47, no. 7, p. 2380-2391, https://doi.org/10.1109/TGRS.2009.2013206.","productDescription":"12 p.","startPage":"2380","endPage":"2391","numberOfPages":"12","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":246213,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218222,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/TGRS.2009.2013206"}],"volume":"47","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaf84e4b0c8380cd87625","contributors":{"authors":[{"text":"Chander, G.","contributorId":51449,"corporation":false,"usgs":true,"family":"Chander","given":"G.","affiliations":[],"preferred":false,"id":455244,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Saunier, S.","contributorId":96914,"corporation":false,"usgs":true,"family":"Saunier","given":"S.","email":"","affiliations":[],"preferred":false,"id":455245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Choate, M.J.","contributorId":41194,"corporation":false,"usgs":true,"family":"Choate","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":455243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Scaramuzza, P.

Additionally, we describe one nest that was moved after the habitat at the nest site had been disturbed by domestic cattle. Our observations and evidence indicate that adult Piping Plovers are capable of moving eggs and establishing nests at new sites during incubation. Furthermore, our results suggest that Piping Plovers evaluate their reproductive investment under potential threat of nest loss and may be capable of acting prospectively (moving nests prior to inundation) and reactively (regathering eggs after inundation) to avoid nest failure.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1525/cond.2009.080106","issn":"00105422","usgsCitation":"Wiltermuth, M.T., Anteau, M.J., Sherfy, M.H., and Shaffer, T.L., 2009, Nest movement by piping plovers in response to changing habitat conditions: Condor, v. 111, no. 3, p. 550-555, https://doi.org/10.1525/cond.2009.080106.","productDescription":"6 p.","startPage":"550","endPage":"555","numberOfPages":"6","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":476147,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/cond.2009.080106","text":"Publisher Index Page"},{"id":246495,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218480,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1525/cond.2009.080106"}],"volume":"111","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a647de4b0c8380cd729d8","contributors":{"authors":[{"text":"Wiltermuth, Mark T. 0000-0002-8871-2816 mwiltermuth@usgs.gov","orcid":"https://orcid.org/0000-0002-8871-2816","contributorId":708,"corporation":false,"usgs":true,"family":"Wiltermuth","given":"Mark","email":"mwiltermuth@usgs.gov","middleInitial":"T.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true},{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":454297,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anteau, Michael J. 0000-0002-5173-5870 manteau@usgs.gov","orcid":"https://orcid.org/0000-0002-5173-5870","contributorId":3427,"corporation":false,"usgs":true,"family":"Anteau","given":"Michael","email":"manteau@usgs.gov","middleInitial":"J.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":454296,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sherfy, Mark H. 0000-0003-3016-4105 msherfy@usgs.gov","orcid":"https://orcid.org/0000-0003-3016-4105","contributorId":125,"corporation":false,"usgs":true,"family":"Sherfy","given":"Mark","email":"msherfy@usgs.gov","middleInitial":"H.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":454298,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shaffer, Terry L. 0000-0001-6950-8951 tshaffer@usgs.gov","orcid":"https://orcid.org/0000-0001-6950-8951","contributorId":3192,"corporation":false,"usgs":true,"family":"Shaffer","given":"Terry","email":"tshaffer@usgs.gov","middleInitial":"L.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":454299,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The products of these reductive transformations depend on both the organism involved and the reduction conditions employed, in terms of electron donor and exogenous extracellular redox mediator. The intermediary phase involves the precipitation of elemental selenium nanospheres and the potential role of proteins in the formation of these structures is discussed. The bionanomineral phases produced during these transformations, including both elemental selenium nanospheres and metal selenide nanoparticles, have catalytic, semiconducting and light-emitting properties, which may have unique applications in the realm of nanophotonics. This research offers the potential to combine remediation of contaminants with the development of environmentally friendly manufacturing pathways for novel bionanominerals. ?? 2009 Taylor & Francis.","publisher":"Taylor & Francis","doi":"10.1080/09593330902984751","issn":"09593330","usgsCitation":"Pearce, C., Pattrick, R., Law, N., Charnock, J., Coker, V., Fellowes, J., Oremland, R., and Lloyd, J., 2009, Investigating different mechanisms for biogenic selenite transformations: <i>Geobacter sulfurreducens</i>, <i>Shewanella oneidensis</i> and <i>Veillonella atypica</i>: Environmental Technology, v. 30, no. 12, p. 1313-1326, https://doi.org/10.1080/09593330902984751.","productDescription":"14 p.","startPage":"1313","endPage":"1326","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":476155,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"text":"External Repository"},{"id":246589,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/09593330902984751"}],"volume":"30","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3e67e4b0c8380cd63d5d","contributors":{"authors":[{"text":"Pearce, C.I.","contributorId":65315,"corporation":false,"usgs":true,"family":"Pearce","given":"C.I.","email":"","affiliations":[],"preferred":false,"id":454123,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pattrick, R.A.D.","contributorId":13761,"corporation":false,"usgs":true,"family":"Pattrick","given":"R.A.D.","email":"","affiliations":[],"preferred":false,"id":454119,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Law, N.","contributorId":107970,"corporation":false,"usgs":true,"family":"Law","given":"N.","email":"","affiliations":[],"preferred":false,"id":454126,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Charnock, J.M.","contributorId":38296,"corporation":false,"usgs":true,"family":"Charnock","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":454121,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Coker, V.S.","contributorId":24612,"corporation":false,"usgs":true,"family":"Coker","given":"V.S.","email":"","affiliations":[],"preferred":false,"id":454120,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Fellowes, J.W.","contributorId":85451,"corporation":false,"usgs":true,"family":"Fellowes","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":454124,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Oremland, R.S.","contributorId":97512,"corporation":false,"usgs":true,"family":"Oremland","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":454125,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Lloyd, J.R.","contributorId":42769,"corporation":false,"usgs":true,"family":"Lloyd","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":454122,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}
