Average DOC concentrations nearly doubled from winter baseflow (2.75 mg L-1) to summer irrigation (5.14 mg L-1), while a concomitant increase in carbon-normalized vanillyl phenols (0.11 mg 100 mg OC-1 increasing to 0.31 mg 100 mg OC-1, on average) indicates that this additional carbon is likely vascular plant-derived. A strong linear relationship between lignin concentration and total suspended sediments (r2 = 0.79) demonstrates that agricultural management practices that mobilize sediments will likely have a direct and significant impact on DOC composition. The original source of vascular plant-derived DOC to Willow Slough appears to be the same throughout the year as evidenced by similar syringyl to vanillyl and cinnamyl to vanillyl ratios. However, differing diagenetic pathways during winter baseflow as compared to the rest of the year are evident in acid to aldehyde ratios of both vanillyl and syringyl phenols. The chromophoric dissolved organic matter (CDOM) absorption coefficient at 350 nm showed a strong correlation with lignin concentration (r2 = 0.83). Other CDOM measurements related to aromaticity and molecular weight also showed correlations with carbon-normalized yields (e.g. specific UV absorbance at 254 nm (r2 = 0.57) and spectral slope (r2 = 0.54)). Our overall findings suggest that irrigated agricultural watersheds like Willow Slough can potentially have a significant impact on mainstem DOC concentration and composition when scaled to the entire watershed of the main tributary. ?? 2008 Elsevier Ltd.","language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2008.07.031","issn":"00167","usgsCitation":"Hernes, P., Spencer, R., Dyda, R., Pellerin, B., Bachand, P., and Bergamaschi, B., 2008, The role of hydrologic regimes on dissolved organic carbon composition in an agricultural watershed: Geochimica et Cosmochimica Acta, v. 72, no. 21, p. 5266-5277, https://doi.org/10.1016/j.gca.2008.07.031.","productDescription":"12 p.","startPage":"5266","endPage":"5277","numberOfPages":"12","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":239497,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212079,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2008.07.031"}],"volume":"72","issue":"21","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baf77e4b08c986b3247fa","contributors":{"authors":[{"text":"Hernes, P.J.","contributorId":89651,"corporation":false,"usgs":true,"family":"Hernes","given":"P.J.","affiliations":[],"preferred":false,"id":428013,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spencer, R.G.M.","contributorId":60361,"corporation":false,"usgs":true,"family":"Spencer","given":"R.G.M.","email":"","affiliations":[],"preferred":false,"id":428011,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dyda, R.Y.","contributorId":59630,"corporation":false,"usgs":true,"family":"Dyda","given":"R.Y.","email":"","affiliations":[],"preferred":false,"id":428010,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pellerin, B.A.","contributorId":81233,"corporation":false,"usgs":true,"family":"Pellerin","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":428012,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bachand, P.A.M.","contributorId":9857,"corporation":false,"usgs":true,"family":"Bachand","given":"P.A.M.","email":"","affiliations":[],"preferred":false,"id":428008,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bergamaschi, B.A. 0000-0002-9610-5581","orcid":"https://orcid.org/0000-0002-9610-5581","contributorId":22401,"corporation":false,"usgs":true,"family":"Bergamaschi","given":"B.A.","affiliations":[],"preferred":false,"id":428009,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Extensive wetlands in the southeastern United States have many ecosystem attributes ideal for promoting high MeHg production rates; however, relatively few mercury cycling studies have been conducted in these environments. We conducted a landscape scale study examining Hg cycling in coastal Louisiana (USA) including four field trips conducted between August 2003 and May 2005. Sites were chosen to represent different ecosystem types, including: a large shallow eutrophic estuarine lake (Lake Pontchartrain), three rivers draining into the lake, a cypress-tupelo dominated freshwater swamp, and six emergent marshes ranging from a freshwater marsh dominated by<span>&nbsp;</span><i>Panicum hemitomon</i><span>&nbsp;</span>to a<span>&nbsp;</span><i>Spartina alterniflora</i><span>&nbsp;</span>dominated salt marsh close to the Gulf of Mexico.

Concentrations of THg and MeHg in filtered surface water were positively correlated with the highly reactive, aromatic (hydrophobic organic acid) fraction of dissolved organic carbon (DOC). These results suggest that DOC plays an important role in promoting the mobility, transport and bioavailability of inorganic Hg in these environments.

In this simulation, AVIRIS images were converted to radiance, then spectrally resampled to six wavelength bands commonly used for terrestrial observation. Preliminary results indicate that differences between the simulations can be attributed to variations in surface reflectance within spectral bands, and suggest influences due to water vapor absorption. Radiance simulated from the spectrally narrow Moderate Resolution Imaging Spectroradiometer (MODIS) relative spectral responses (RSR) was generally higher than that using the broader Enhanced Thematic Mapper Plus (ETM+) RSRs over most targets encountered over the test area. This is consistent with many MODIS bands being biased toward shorter wavelengths compared to corresponding ETM+ bands when viewing targets whose radiance decreases with wavelength. In some cases the higher radiance values appeared to occur where the MODIS RSR is better situated over peak reflected wavelengths. Simulation differences between MODIS &amp; ETM+ bands in the near-infrared indicated higher MODIS radiance values that suggest the influence of water vapor absorption at 820 nanometers.

The elemental composition of about 300 molecules was identified. Those in the HPO fraction (14C age of 5100 year) are very similar to much younger freshwater fulvic acids, but less aromatic and more oxygenated molecules are more frequent. This trend continues toward the HPI fraction and may indicate biotic and abiotic aging processes that this material experienced since its primary production thousands of years ago. In the HPI fraction series of nitrogenous molecules containing one, two, or three nitrogens were identified by FTICR-MS. Product ion spectra of the nitrogenous molecules suggest that the nitrogen atoms in these molecules are included in the (alicyclic) backbone of these molecules, possibly in reduced form. These mass spectrometric data suggest that a large set of stable fulvic acids is ubiquitous in all aquatic compartments. Although sources may differ, their actual composition and structure appears to be quite similar and largely independent from their source, because they are the remainder of intensive oxidative degradation processes. ?? 2008 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es7021413","issn":"0013936X","usgsCitation":"Reemtsma, T., These, A., Linscheid, M., Leenheer, J., and Spitzy, A., 2008, Molecular and structural characterization of dissolved organic matter from the deep ocean by FTICR-MS, including hydrophilic nitrogenous organic molecules: Environmental Science & Technology, v. 42, no. 5, p. 1430-1437, https://doi.org/10.1021/es7021413.","startPage":"1430","endPage":"1437","numberOfPages":"8","costCenters":[],"links":[{"id":214909,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es7021413"},{"id":242669,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"42","issue":"5","noUsgsAuthors":false,"publicationDate":"2008-02-01","publicationStatus":"PW","scienceBaseUri":"505a5cf7e4b0c8380cd7007f","contributors":{"authors":[{"text":"Reemtsma, T.","contributorId":35608,"corporation":false,"usgs":true,"family":"Reemtsma","given":"T.","email":"","affiliations":[],"preferred":false,"id":434998,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"These, A.","contributorId":89025,"corporation":false,"usgs":true,"family":"These","given":"A.","email":"","affiliations":[],"preferred":false,"id":435000,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Linscheid, M.","contributorId":101531,"corporation":false,"usgs":true,"family":"Linscheid","given":"M.","email":"","affiliations":[],"preferred":false,"id":435001,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Leenheer, J.","contributorId":71714,"corporation":false,"usgs":true,"family":"Leenheer","given":"J.","affiliations":[],"preferred":false,"id":434999,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Spitzy, A.","contributorId":33593,"corporation":false,"usgs":true,"family":"Spitzy","given":"A.","email":"","affiliations":[],"preferred":false,"id":434997,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We compared characteristics of vegetation at 19 sites in nine mountain ranges of the western Great Basin; sites were either grazed by feral horses (Equus caballus) or had had horses removed for the last 10-14 years. We selected horse-occupied and horse-removed sites with similar aspect, slope, fire history, grazing pressure by cattle (minimal to none), and dominant vegetation (Artemisia tridentata). During 1997 and 1998, line-intercept transects randomly located within sites revealed that horse-removed sites exhibited 1.1-1.9 times greater shrub cover, 1.2-1.5 times greater total plant cover, 2-12 species greater plant species richness, and 1.9-2.9 times greater cover and 1.1-2.4 times greater frequency of native grasses than did horse-occupied sites. In contrast, sites with horses tended to have more grazing-resistant forbs and exotic plants. Direction and magnitude of landscape-scale results were corroborated by smaller-scale comparisons within horse-occupied sites of horse-trail transects and (randomly located) transects that characterized overall site conditions. Information-theoretic analyses that incorporated various subsets of abiotic variables suggested that presence of horses was generally a strong determinant of those vegetation-related variables that differed significantly between treatments, especially frequency and cover of grasses, but also species richness and shrub cover and frequency. In contrast, abiotic variables such as precipitation, site elevation, and soil erodibility best predicted characteristics such as forb cover, shrub frequency, and continuity of the shrub canopy. We found species richness of plants monotonically decreased across sites as grazing disturbance increased, suggesting that either the bell-shaped diversity-disturbance curve of the intermediate-disturbance hypothesis does not apply in this system or that most sites are already all on the greater-disturbance slope of the curve. In our study, numerous vegetation properties of less-grazed areas and sites differed notably from horse-grazed sites at local and landscape scales during a wetter and an average-precipitation year. ?? 2007 Springer Science+Business Media B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Plant Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11258-007-9342-5","issn":"13850237","usgsCitation":"Beever, E., Tausch, R., and Thogmartin, W., 2008, Multi-scale responses of vegetation to removal of horse grazing from Great Basin (USA) mountain ranges: Plant Ecology, v. 196, no. 2, p. 163-184, https://doi.org/10.1007/s11258-007-9342-5.","startPage":"163","endPage":"184","numberOfPages":"22","costCenters":[],"links":[{"id":212583,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11258-007-9342-5"},{"id":240088,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"196","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-09-06","publicationStatus":"PW","scienceBaseUri":"505a5fc4e4b0c8380cd7110b","contributors":{"authors":[{"text":"Beever, E.A.","contributorId":80040,"corporation":false,"usgs":true,"family":"Beever","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":433183,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tausch, R.J.","contributorId":32642,"corporation":false,"usgs":true,"family":"Tausch","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":433182,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thogmartin, W.E. 0000-0002-2384-4279","orcid":"https://orcid.org/0000-0002-2384-4279","contributorId":26392,"corporation":false,"usgs":true,"family":"Thogmartin","given":"W.E.","affiliations":[],"preferred":false,"id":433181,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Fish assemblage and relative density differed in the lateral habitats of the middle-regulated and upper-unregulated sections of the Elwha River. Rainbow trout was the numerically dominant salmonid in both sections, with bull trout present in low numbers. Sculpin were common in the middle section, but not detected in the upper section. In 2004, mean length and biomass of age-0 rainbow trout were significantly smaller in the middle section than in the upper section by the end of the growing season (September). In 2005, an earlier emergence of rainbow trout in the middle section (July) compared to the upper section (August) corresponded with warmer water temperatures in the middle section. Despite lower growth, the margins of mainstem units in the middle section supported higher mean areal densities and biomass of age-0 rainbow trout than the up-per section. These results suggest that growth performance of age-0 rainbow trout was lower in the middle section than in the upper section, which could have been a density-dependent response, or a result of poor food production in the sediment-starved regulated section, or both.

Age estimation represents an integral component in the management of Lake Erie yellow perch stocks, as age-structured population models are used to set safe harvest levels on an annual basis. We compared the precision associated with yellow perch (N = 251) age estimates from scales, sagittal otoliths, and anal spine sections and evaluated the time required to process and estimate age from each structure. Three readers of varying experience estimated ages. The precision (mean coefficient of variation) of estimates among readers was 1% for sagittal otoliths, 5-6% for anal spines, and 11-13% for scales. Agreement rates among readers were 94-95% for otoliths, 71-76% for anal spines, and 45-50% for scales. Systematic age estimation differences were evident among scale and anal spine readers; less-experienced readers tended to underestimate ages of yellow perch older than age 4 relative to estimates made by an experienced reader. Mean scale age tended to underestimate ages of age-6 and older fish relative to otolith ages estimated by an experienced reader. Total annual mortality estimates based on scale ages were 20% higher than those based on otolith ages; mortality estimates based on anal spine ages were 4% higher than those based on otolith ages. Otoliths required more removal and preparation time than scales and anal spines, but age estimation time was substantially lower for otoliths than for the other two structures. We suggest the use of otoliths or anal spines for age estimation in yellow perch (regardless of length) from Lake Erie and other systems where precise age estimates are necessary, because age estimation errors resulting from the use of scales could generate incorrect management decisions. ??

We combined these two complimentary methods to define the spatial pattern of genetic structure among remaining populations of the threatened Florida scrub-jay, a species for which dispersal ability is unusually well-characterized. The range-wide population was intensively censused in the 1990s, and a metapopulation model defined population boundaries based on predicted dispersal-mediated demographic connectivity. We subjected genotypes from more than 1000 individual jays screened at 20 microsatellite loci to two Bayesian clustering methods. We describe a consensus method for identifying common features across many replicated clustering runs. Ten genetically differentiated groups exist across the present-day range of the Florida scrub-jay. These groups are largely consistent with the dispersal-defined metapopulations, which assume very limited dispersal ability. Some genetic groups comprise more than one metapopulation, likely because these genetically similar metapopulations were sundered only recently by habitat alteration. The combined reconstructions of population structure based on genetics and dispersal-mediated demographic connectivity provide a robust depiction of the current genetic and demographic organization of this species, reflecting past and present levels of dispersal among occupied habitat patches. The differentiation of populations into 10 genetic groups adds urgency to management efforts aimed at preserving what remains of genetic variation in this dwindling species, by maintaining viable populations of all genetically differentiated and geographically isolated populations.</p>","language":"English","publisher":"Blackwell Publishing","doi":"10.1111/j.1365-294X.2008.03705.x","issn":"09621083","usgsCitation":"Coulon, A., Fitzpatrick, J., Bowman, R., Stith, B., Makarewich, C., Stenzler, L., and Lovette, I., 2008, Congruent population structure inferred from dispersal behaviour and intensive genetic surveys of the threatened Florida scrub-jay (<i>Aphelocoma cœrulescens</i>): Molecular Ecology, v. 17, no. 7, p. 1685-1701, https://doi.org/10.1111/j.1365-294X.2008.03705.x.","productDescription":"17 p.","startPage":"1685","endPage":"1701","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":239747,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212284,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-294X.2008.03705.x"}],"country":"United States","state":"Florida","volume":"17","issue":"7","noUsgsAuthors":false,"publicationDate":"2008-03-25","publicationStatus":"PW","scienceBaseUri":"5059f9c6e4b0c8380cd4d78d","contributors":{"authors":[{"text":"Coulon, A.","contributorId":20973,"corporation":false,"usgs":true,"family":"Coulon","given":"A.","email":"","affiliations":[],"preferred":false,"id":433231,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fitzpatrick, J.W.","contributorId":33012,"corporation":false,"usgs":true,"family":"Fitzpatrick","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":433232,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bowman, R.","contributorId":12012,"corporation":false,"usgs":true,"family":"Bowman","given":"R.","email":"","affiliations":[],"preferred":false,"id":433229,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stith, B.M.","contributorId":53741,"corporation":false,"usgs":true,"family":"Stith","given":"B.M.","email":"","affiliations":[],"preferred":false,"id":433233,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Makarewich, C.A.","contributorId":66065,"corporation":false,"usgs":true,"family":"Makarewich","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":433234,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stenzler, L.M.","contributorId":93699,"corporation":false,"usgs":true,"family":"Stenzler","given":"L.M.","email":"","affiliations":[],"preferred":false,"id":433235,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Lovette, I.J.","contributorId":19252,"corporation":false,"usgs":true,"family":"Lovette","given":"I.J.","email":"","affiliations":[],"preferred":false,"id":433230,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Several diagnostic tests are available for detection of SVCV. However, most of these tests are time consuming and are not well adapted for field-based diagnostics. In this study, a diagnostic tool for SVCV detection based on reverse transcription loop-mediated isothermal amplification (RT-LAMP) has been developed. Based on the nucleotide sequence of the glycoprotein (G) gene of SVCV North Carolina (NC) isolate, four sets (each set containing two outer and two inner) of primers were designed. Temperature and time conditions were optimized to 65 ??C and 60 min, respectively, for LAMP and RT-LAMP using one primer set. In vitro specificity was evaluated using four different strains of fish rhabdoviruses and RT-LAMP was found to be specific to SVCV. Serial dilutions of SVCV NC isolate was used to evaluate the in vitro sensitivity of RT-LAMP. Sensitivity of the assays was similar to RT-PCR and detected SVCV even at the lowest dilution of 10 1 TCID50 mL-1. The ability of RT-LAMP to detect SVCV from infected carp was also tested and the assay detected SVCV from all infected fish. The isothermal temperature requirements, high specificity and sensitivity, and short incubation time of the RT-LAMP assay make it an excellent choice as a field diagnostic test for SVCV. ?? 2008 The Authors.","language":"English","publisher":"Wiley ","doi":"10.1111/j.1365-2761.2007.00894.x","issn":"01407775","usgsCitation":"Shivappa, R., Savan, R., Kono, T., Sakai, M., Emmenegger, E., Kurath, G., and Levine, J.F., 2008, Detection of spring viraemia of carp virus (SVCV) by loop-mediated isothermal amplification (LAMP) in koi carp, Cyprinus carpio L: Journal of Fish Diseases, v. 31, no. 4, p. 249-258, https://doi.org/10.1111/j.1365-2761.2007.00894.x.","productDescription":"10 p.","startPage":"249","endPage":"258","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":239779,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212313,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2761.2007.00894.x"}],"volume":"31","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-03-18","publicationStatus":"PW","scienceBaseUri":"5059ff78e4b0c8380cd4f1ed","contributors":{"authors":[{"text":"Shivappa, R.B.","contributorId":56022,"corporation":false,"usgs":true,"family":"Shivappa","given":"R.B.","email":"","affiliations":[],"preferred":false,"id":433239,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Savan, R.","contributorId":27261,"corporation":false,"usgs":true,"family":"Savan","given":"R.","email":"","affiliations":[],"preferred":false,"id":433236,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kono, T.","contributorId":94859,"corporation":false,"usgs":true,"family":"Kono","given":"T.","email":"","affiliations":[],"preferred":false,"id":433241,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sakai, M.","contributorId":33533,"corporation":false,"usgs":true,"family":"Sakai","given":"M.","email":"","affiliations":[],"preferred":false,"id":433237,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Emmenegger, E.","contributorId":34324,"corporation":false,"usgs":true,"family":"Emmenegger","given":"E.","email":"","affiliations":[],"preferred":false,"id":433238,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kurath, Gael 0000-0003-3294-560X gkurath@usgs.gov","orcid":"https://orcid.org/0000-0003-3294-560X","contributorId":100522,"corporation":false,"usgs":true,"family":"Kurath","given":"Gael","email":"gkurath@usgs.gov","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":433242,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Levine, Jay F.","contributorId":80902,"corporation":false,"usgs":false,"family":"Levine","given":"Jay","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":433240,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

The availability of energy and essential nutrients to top predators such as seabirds that rely on resources near the water's surface will be affected by changes in pelagic prey abundance. Here, we present results from analysis of a 25-year data set documenting dietary change in a predatory seabird from the Laurentian Great Lakes. We reveal significant declines in trophic position and alterations in energy and nutrient flow over time. Temporal changes in seabird diet tracked decreases in pelagic prey fish abundance. As pelagic prey abundance declined, birds consumed less aquatic prey and more terrestrial food. This pattern was consistent across all five large lake ecosystems. Declines in prey fish abundance may have primarily been the result of predation by stocked piscivorous fishes, but other lake-specific factors were likely also important. Natural resource management activities can have unintended consequences for nontarget ecosystem components. Reductions in pelagic prey abundance have reduced the capacity of the Great Lakes to support the energetic requirements of surface-feeding seabirds. In an environment characterized by increasingly limited pelagic fish resources, they are being offered a Hobsonian choice: switch to less nutritious terrestrial prey or go hungry. ?? 2008 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/07-1603.1","issn":"00129658","usgsCitation":"Hebert, C., Weseloh, D., Idrissi, A., Arts, M., O'Gorman, R., Gorman, O.T., Locke, B., Madenjian, C., and Roseman, E., 2008, Restoring piscivorous fish populations in the Laurentian Great Lakes causes seabird dietary change: Ecology, v. 89, no. 4, p. 891-897, https://doi.org/10.1890/07-1603.1.","startPage":"891","endPage":"897","numberOfPages":"7","costCenters":[],"links":[{"id":214756,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/07-1603.1"},{"id":242506,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"89","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaae5e4b0c8380cd865b2","contributors":{"authors":[{"text":"Hebert, C.E.","contributorId":44369,"corporation":false,"usgs":true,"family":"Hebert","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":434946,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weseloh, D.V.C.","contributorId":35703,"corporation":false,"usgs":true,"family":"Weseloh","given":"D.V.C.","email":"","affiliations":[],"preferred":false,"id":434945,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Idrissi, A.","contributorId":46783,"corporation":false,"usgs":true,"family":"Idrissi","given":"A.","affiliations":[],"preferred":false,"id":434947,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Arts, M.T.","contributorId":12685,"corporation":false,"usgs":true,"family":"Arts","given":"M.T.","email":"","affiliations":[],"preferred":false,"id":434944,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"O'Gorman, R.","contributorId":48896,"corporation":false,"usgs":true,"family":"O'Gorman","given":"R.","affiliations":[],"preferred":false,"id":434948,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Gorman, O.

We used repeat digital photography and image analysis, which revealed a change in area of a dominant BSC lichen, Collema tenax. The data generated correlated well with gross photosynthesis (r=0.57) and carotenoid content (r=0.53), two variables that would be expected to be positively related to lichen area. We also extracted fatty acids from lichen samples and identified useful phospholipid fatty acid (PLFA) indicators for the Collema mycobiont (20:1, 15:0, 23:0), and the Collema photobiont (18:3??3). The 18:3??3 correlated well with chlorophyll a (r=0.66), a more traditional proxy for cyanobacterial biomass. We also compared total PLFA as a proxy for total Collema biomass with our photographically generated areal change data, and found them to be moderately correlated (r=0.44). Areal change proved to be responsive on short-time scales, while fatty acid techniques were information-rich, providing data on biomass of lichens, and both photo- and mycobionts separately, in addition to the physiological status of the mycobiont. Both techniques should be refined and tested in field situations. ?? 2007 Elsevier Ltd.

Therefore, aeolian deposits may be an archive of past environmental changes, possibly at the millennial scale, but previous studies on this topic have rarely been reported. In this study, thirty-five optically stimulated luminescence (OSL) ages of ten representative sand-paleosol profiles in Otindag sand field are obtained, and these ages provide a relatively complete and well-dated chronology for wet and dry variations in Holocene. The results indicate that widespread dune mobilization occurred from 9.9 to 8.2 ka, suggesting a dry early Holocene climate. The dunes were mainly stabilized between 8.0 and 2.7 ka, implying a relatively wet climate, although there were short-term penetrations of dune activity during this wet period. After ???2.3 ka, the region became dry again, as inferred from widespread dune activity. The \"8.2 ka\" cold event and the Little Ice Age climatic deterioration are detected on the basis of the dune records and OSL ages. During the Medieval Warm Period and the Sui-Tang Warm Period (570-770 AD), climate in Otindag sand field was relatively humid and the vegetation was denser, and the sand dunes were stabilized again. These aeolian records may indicate climate changes at millennial time scale during Holocene, and these climatic changes may be the teleconnection to the climate changes elsewhere in the world. ??

The results show significant differences in the individual genes that were differentially expressed in response to each treatment. In liver, a total of 650 genes exhibited significantly (P < 0.05) altered expression with greater than two-fold differences from the controls in response to acute exposure and a total of 267 genes were differentially expressed in response to chronic exposure. A majority of these genes were downregulated rather than upregulated. Fewer genes were altered in gonad than in liver at both timepoints. A total of 212 genes were differentially expressed in response to acute exposure and 155 genes were altered in response to chronic exposure. Despite the differences in individual genes expressed across treatments, the functional categories that altered genes were associated with showed some similarities. Of interest in light of other studies involving the effects of methylmercury on fish, several genes associated with apoptosis were upregulated in response to both acute and chronic exposures. Induction of apoptosis has been associated with effects on reproduction seen in the previous studies. This study demonstrates the utility of microarray analysis for investigations of the physiological effects of toxicants as well as the time-course of effects that may take place.

In the 1980s and early 1990s, we conducted a geological and geophysical investigation, known as the Trans-Alaska Crustal Transect (TACT), along a 1350-km-long corridor from the Aleutian Trench to the Arctic coast. The most distinctive crustal structures and the deepest Moho along the transect are located near the Pacific and Arctic margins. Near the Pacific margin, we infer a stack of tectonically underplated oceanic layers interpreted as remnants of the extinct Kula (or Resurrection) plate. Continental Moho just north of this underplated stack is more than 55 km deep. Near the Arctic margin, the Brooks Range is underlain by large-scale duplex structures that overlie a tectonic wedge of North Slope crust and mantle. There, the Moho has been depressed to nearly 50 km depth. In contrast, the Moho of central Alaska is on average 32 km deep. In the Paleogene, tectonic underplating of Kula (or Resurrection) plate fragments overlapped in time with duplexing in the Brooks Range. Possible tectonic models linking these two regions include flat-slab subduction and an orogenic-float model. In the Neogene, the tectonics of the accreting Yakutat terrane have differed across a newly interpreted tear in the subducting Pacific oceanic lithosphere. East of the tear, Pacific oceanic lithosphere subducts steeply and alone beneath the Wrangell volcanoes, because the overlying Yakutat terrane has been left behind as underplated rocks beneath the rising St. Elias Range, in the coastal region. West of the tear, the Yakutat terrane and Pacific oceanic lithosphere subduct together at a gentle angle, and this thickened package inhibits volcanism.&nbsp;</p>","largerWorkTitle":"","language":"English","publisher":"Geological Society of America","doi":"10.1130/G24257A.1","issn":"00917613","usgsCitation":"Fuis, G.S., Moore, T., Plafker, G., Brocher, T., Fisher, M.A., Mooney, W.D., Nokleberg, W., Page, R., Beaudoin, B.C., Christensen, N., Levander, A.R., Lutter, W.J., Saltus, R.W., and Ruppert, N., 2008, Trans-Alaska Crustal Transect and continental evolution involving subduction underplating and synchronous foreland thrusting: Geology, v. 36, no. 3, p. 267-270, https://doi.org/10.1130/G24257A.1.","productDescription":"4 p.","startPage":"267","endPage":"270","numberOfPages":"4","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":242383,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -154.86328125,\n              58.17070248348609\n            ],\n            [\n              -133.59375,\n              58.17070248348609\n            ],\n            [\n              -133.59375,\n              65.5129625532949\n            ],\n            [\n              -154.86328125,\n              65.5129625532949\n            ],\n            [\n              -154.86328125,\n              58.17070248348609\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"36","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb6b9e4b08c986b326e39","contributors":{"authors":[{"text":"Fuis, Gary S. 0000-0002-3078-1544 fuis@usgs.gov","orcid":"https://orcid.org/0000-0002-3078-1544","contributorId":2639,"corporation":false,"usgs":true,"family":"Fuis","given":"Gary","email":"fuis@usgs.gov","middleInitial":"S.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":433553,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, Thomas E. 0000-0002-0878-0457","orcid":"https://orcid.org/0000-0002-0878-0457","contributorId":85592,"corporation":false,"usgs":true,"family":"Moore","given":"Thomas E.","affiliations":[],"preferred":false,"id":433555,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plafker, George 0000-0003-3972-0390","orcid":"https://orcid.org/0000-0003-3972-0390","contributorId":36603,"corporation":false,"usgs":true,"family":"Plafker","given":"George","affiliations":[],"preferred":false,"id":433547,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brocher, T.M. 0000-0002-9740-839X","orcid":"https://orcid.org/0000-0002-9740-839X","contributorId":69994,"corporation":false,"usgs":true,"family":"Brocher","given":"T.M.","affiliations":[],"preferred":false,"id":433551,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fisher, M.

We assessed the distribution and abundance of spawning, non-spawning adult and larval capelin in Glacier Bay, an estuarine fjord system in southeastern Alaska. We used principal components analysis to analyze midwater trawl and beach seine data collected between 1999 and 2004 with respect to oceanographic data and other measures of physical habitat including proximity to tidewater glaciers and potential spawning habitat. Both spawning and non-spawning adult Pacific capelin were more likely to occur in areas closest to tidewater glaciers, and those areas were distinguished by lower temperature, higher turbidity, higher dissolved oxygen and lower chlorophyll a levels when compared with other areas of the bay. The distribution of larval Pacific capelin was not sensitive to glacial influence. Pre-spawning females collected farther from tidewater glaciers were at a lower maturity state than those sampled closer to tidewater glaciers, and the geographic variation in the onset of spawning is likely the result of differences in the marine habitat among sub-areas of Glacier Bay. Proximity to cold water in Glacier Bay may have provided a refuge for capelin during the recent warm years in the Gulf of Alaska.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fisheries Oceanography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2419.2008.00470.x","issn":"10546006","usgsCitation":"Arimitsu, M.L., Piatt, J.F., Litzow, M.A., Abookire, A.A., Romano, M.D., and Robards, M.D., 2008, Distribution and spawning dynamics of capelin (Mallotus villosus) in Glacier Bay, Alaska: A cold water refugium: Fisheries Oceanography, v. 17, no. 2, p. 137-146, https://doi.org/10.1111/j.1365-2419.2008.00470.x.","startPage":"137","endPage":"146","numberOfPages":"10","costCenters":[],"links":[{"id":242452,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214704,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2419.2008.00470.x"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationDate":"2008-03-27","publicationStatus":"PW","scienceBaseUri":"505a02a3e4b0c8380cd5013e","contributors":{"authors":[{"text":"Arimitsu, Mayumi L. 0000-0001-6982-2238 marimitsu@usgs.gov","orcid":"https://orcid.org/0000-0001-6982-2238","contributorId":140501,"corporation":false,"usgs":true,"family":"Arimitsu","given":"Mayumi","email":"marimitsu@usgs.gov","middleInitial":"L.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":433570,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Piatt, John F. 0000-0002-4417-5748 jpiatt@usgs.gov","orcid":"https://orcid.org/0000-0002-4417-5748","contributorId":3025,"corporation":false,"usgs":true,"family":"Piatt","given":"John","email":"jpiatt@usgs.gov","middleInitial":"F.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":433573,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Litzow, Michael A.","contributorId":8789,"corporation":false,"usgs":true,"family":"Litzow","given":"Michael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":433569,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Abookire, Alisa A.","contributorId":107224,"corporation":false,"usgs":true,"family":"Abookire","given":"Alisa","email":"","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":433574,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Romano, Marc D.","contributorId":73528,"corporation":false,"usgs":true,"family":"Romano","given":"Marc","email":"","middleInitial":"D.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":433572,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Robards, Martin D.","contributorId":40148,"corporation":false,"usgs":false,"family":"Robards","given":"Martin","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":433571,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Four small-bodied riverine species were examined in our comparison of the two methods. Mean GSI was significantly different between all histological stages for suckermouth minnow and red shiner. Mean GSI was significantly different between most stages for slenderhead darter; whereas stages 3 and 6 were not significantly different, the time period when these stages are present would allow fisheries biologists to distinguish between the two stages. Mean GSI was not significantly different for many histological stages in stonecat. Difficulties in distinguishing between histological stages and GSI associated with stonecat illustrate potential problems obtaining appropriate sample sizes from species that move to alternative habitats to spawn. We suggest that GSI would be a useful tool in identifying mature ovaries in many small-bodied, multiple-spawning fishes.

The disk-resolved observations revealed a spatially nonuniform emission in the wavelength range of 200-1050 nm (clear filters). By building on observations and simulations of Europa's Na atmosphere and torus we find that electron-excited Na in Europa's tenuous atmosphere can account for the observed emission if the Na is ejected preferentially from Europa's dark terrain.

Rivers in this area carry significant aqueous and particulate contaminant loads derived from irrigation water associated with the extensive agricultural activity, as well as wastewater from small and large municipalities. A variety of inorganic constituents, including trace metals, nutrients, and organic carbon were analyzed on suspended material isolated from water samples collected at upriver, near-shore, and off-shore sites established on the Alamo, New, and Whitewater rivers. Concentration patterns showed expected trends, with river-borne metals becoming diluted by organic-rich algal particles of lacustrine origin in off-shore stations. More soluble metals, such as cadmium, copper, and zinc showed a more even distribution between sites in the rivers and off-shore in the lake basin. General distributional trends of trace elements between particulate and aqueous forms were discerned by combining metal concentration data for particulates from this study with historical aqueous metals data. Highly insoluble trace metals, such as iron and aluminum, occurred almost entirely in the particulate phase, while major cations and approximately 95% of selenium were transported in the soluble phase. Evidence for greater reducing conditions in the New compared to the Alamo River was provided by the greater proportion of reduced (soluble) manganese in the New River. Evidence of bioconcentration of selenium and arsenic within the lake by algae was provided by calculating \"enrichment\" concentration ratios from metal concentrations on the algal-derived particulate samples and the off-shore sites. ?? 2008 Springer Science+Business Media B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10750-008-9319-y","issn":"00188158","usgsCitation":"LeBlanc, L., and Schroeder, R.A., 2008, Transport and distribution of trace elements and other selected inorganic constituents by suspended particulates in the Salton Sea Basin, California, 2001: Hydrobiologia, v. 604, no. 1, p. 123-135, https://doi.org/10.1007/s10750-008-9319-y.","startPage":"123","endPage":"135","numberOfPages":"13","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":242522,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214772,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-008-9319-y"}],"volume":"604","issue":"1","noUsgsAuthors":false,"publicationDate":"2008-03-18","publicationStatus":"PW","scienceBaseUri":"505bb73fe4b08c986b327147","contributors":{"authors":[{"text":"LeBlanc, L.A.","contributorId":91660,"corporation":false,"usgs":true,"family":"LeBlanc","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":433597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schroeder, R.

Here we measure the speciation of Pb in controlled and natural organic (O) soil horizons to quantify changes in metal partitioning during SOM decomposition in different forest litters. We provide a link between the sequestration of pollutant Pb in O-horizons, estimated by forest floor Pb inventories, and speciation using synchrotron-based X-ray fluorescence and X-ray absorption spectroscopy. When Pb was introduced to fresh forest Oi samples, it adsorbed primarily to SOM surfaces, but as decomposition progressed over two years in controlled experiments, up to 60% of the Pb was redistributed to pedogenic birnessite and ferrihydrite surfaces. In addition, a significant fraction of pollutant Pb in natural soil profiles was associated with similar mineral phases (???20-35%) and SOM (???65-80%). Conifer forests have at least 2-fold higher Pb burdens in the forest floor relative to deciduous forests due to more efficient atmospheric scavenging and slower organic matter turnover. We demonstrate that pedogenic minerals play an important role in surface soil Pb sequestration, particularly in deciduous forests, and should be considered in any assessment of pollutant Pb mobility. ?? 2008 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es703002b","issn":"0013936X","usgsCitation":"Schroth, A., Bostick, B., Kaste, J., and Friedland, A.J., 2008, Lead sequestration and species redistribution during soil organic matter decomposition: Environmental Science & Technology, v. 42, no. 10, p. 3627-3633, https://doi.org/10.1021/es703002b.","startPage":"3627","endPage":"3633","numberOfPages":"7","costCenters":[],"links":[{"id":214837,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es703002b"},{"id":242589,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"42","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a45d7e4b0c8380cd674e7","contributors":{"authors":[{"text":"Schroth, A.W.","contributorId":79707,"corporation":false,"usgs":true,"family":"Schroth","given":"A.W.","email":"","affiliations":[],"preferred":false,"id":433608,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bostick, B.C.","contributorId":62813,"corporation":false,"usgs":true,"family":"Bostick","given":"B.C.","email":"","affiliations":[],"preferred":false,"id":433607,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kaste, J.M.","contributorId":90114,"corporation":false,"usgs":true,"family":"Kaste","given":"J.M.","affiliations":[],"preferred":false,"id":433609,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Friedland, A.
