Large trees generally have lower rates of mortality than small trees and are more resilient to climate change, but these assumptions have rarely been examined in long-term studies. We combined data from 655 historical (1932-1936) and 210 modern (1988-1999) vegetation plots to examine changes in density of large-diameter trees in Yosemite National Park (3027 km2). We tested the assumption of stability for large-diameter trees, as both individual species and communities of large-diameter trees. Between the 1930s and 1990s, large-diameter tree density in Yosemite declined 24%. Although the decrease was apparent in all forest types, declines were greatest in subalpine and upper montane forests (57.0% of park area), and least in lower montane forests (15.3% of park area). Large-diameter tree densities of 11 species declined while only 3 species increased. Four general patterns emerged: (1) Pinus albicaulis, Quercus chrysolepis, and Quercus kelloggii had increases in density of large-diameter trees occur throughout their ranges; (2) Pinus jeffreyi, Pinus lambertiana, and Pinus ponderosa, had disproportionately larger decreases in large-diameter tree densities in lower-elevation portions of their ranges; (3) Abies concolor and Pinus contorta, had approximately uniform decreases in large-diameter trees throughout their elevational ranges; and (4) Abies magnifica, Calocedrus decurrens, Juniperus occidentalis, Pinus monticola, Pseudotsuga menziesii, and Tsuga mertensiana displayed little or no change in large-diameter tree densities. In Pinus ponderosa-Calocedrus decurrens forests, modern large-diameter tree densities were equivalent whether or not plots had burned since 1936. However, in unburned plots, the large-diameter trees were predominantly A. concolor, C. decurrens, and Q. chrysolepis, whereas P. ponderosa dominated the large-diameter component of burned plots. Densities of large-diameter P. ponderosa were 8.1 trees ha-1 in plots that had experienced fire, but only 0.5 trees ha-1 in plots that remained unburned. ?? 2009 Elsevier B.V.

Conservation efforts for D. couperi have been hindered, in part, because of informational gaps regarding the species, including a lack of data on population ecology and estimates of demographic parameters such as survival. We conducted a 2- year radiotelemetry study of D. couperi on Fort Stewart Military Reservation and adjacent private lands located in southeastern Georgia to assess individual characteristics associated with probability of survival. We used known-fate modeling to estimate survival, and an information-theoretic approach, based on a priori hypotheses, to examine intraspecific differences in survival probabilities relative to individual covariates (sex, size, size standardized by sex, and overwintering location). Annual survival in 2003 and 2004 was 0.89 (95% CI = 0.73-0.97, n = 25) and 0.72 (95% CI = 0.52-0.86; n = 27), respectively. Results indicated that body size, standardized by sex, was the most important covariate determining survival of adult D. couperi, suggesting lower survival for larger individuals within each sex. We are uncertain of the mechanisms underlying this result, but possibilities may include greater resource needs for larger individuals within each sex, necessitating larger or more frequent movements, or a population with older individuals. Our results may also have been influenced by analysis limitations because of sample size, other sources of individual variation, or environmental conditions. ?? 2009 by The Herpetologists' League, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Herpetologica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1655/08-004R1.1","issn":"00180831","usgsCitation":"Hyslop, N., Meyers, J., Cooper, R., and Norton, T., 2009, Survival of radio-implanted drymarchon couperi (Eastern Indigo Snake) in relation to body size and sex: Herpetologica, v. 65, no. 2, p. 199-206, https://doi.org/10.1655/08-004R1.1.","startPage":"199","endPage":"206","numberOfPages":"8","costCenters":[],"links":[{"id":215389,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1655/08-004R1.1"},{"id":243188,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"65","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba2dae4b08c986b31f9f0","contributors":{"authors":[{"text":"Hyslop, N.L.","contributorId":22066,"corporation":false,"usgs":true,"family":"Hyslop","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":449201,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meyers, J.M.","contributorId":54307,"corporation":false,"usgs":true,"family":"Meyers","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":449202,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cooper, R.J.","contributorId":89077,"corporation":false,"usgs":true,"family":"Cooper","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":449204,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Norton, Terry M.","contributorId":71020,"corporation":false,"usgs":true,"family":"Norton","given":"Terry M.","affiliations":[],"preferred":false,"id":449203,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70037134,"text":"70037134 - 2009 - Comparison of humus and till as prospecting material in areas of thick overburden and multiple ice-flow events: An example from northeastern New Brunswick","interactions":[],"lastModifiedDate":"2012-03-12T17:22:10","indexId":"70037134","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2302,"text":"Journal of Geochemical Exploration","active":true,"publicationSubtype":{"id":10}},"title":"Comparison of humus and till as prospecting material in areas of thick overburden and multiple ice-flow events: An example from northeastern New Brunswick","docAbstract":"Thirty-nine elements in humus and till matrix were compared at 109 sites overlying Ag-As-Cu-Mo-Pb-Zn mineralized occurrences in northeastern New Brunswick to assess humus for anomaly identification. Humus element concentrations were not consistently correlative with maximum or minimum concentrations found in the underlying till or bedrock. The humus demonstrated significantly higher mean elemental concentrations than the till for six specific elements: 9 times greater for Mn, 6 times greater for Cd, 5 times greater for Ag and Pb, 3 times greater for Hg, and double the concentration of Zn. Spatial dispersal patterns for these elements were much larger for humus content than that exhibited by the till matrix analysis, but did not delineate a point source. For elements in till, the highest concentrations were commonly found directly overlying the underlying mineralized bedrock source or within one km down-glacier of the source. The complexity of the humus geochemical patterns is attributed to the effects of post-glacial biogenic, down-slope hydrodynamic and solifluction modification of dispersed mineralization in the underlying till, and the greater capacity of humus to adsorb cations and form complexes with some elements, relative to the till matrix. Humus sampling in areas of glaciated terrain is considered to be mostly valuable for reconnaissance exploration as elements can be spatially dispersed over a much larger area than that found in the till or underlying bedrock. ?? 2009 Elsevier B.V.

Testicular oocytes (predominantly male testes containing female germ cells) were the most pervasive form of intersex observed, even though similar numbers of male (n = 1477) and female (n = 1633) fish were examined. Intersex was found in 3% of the fish collected. The intersex condition was observed in four of the 16 species examined (25%) and in fish from 34 of 111 sites (31%). Intersex was not found in multiple species from the same site but was most prevalent in largemouth bass (Micropterus salmoides; 18% of males) and smallmouth bass (M. dolomieu; 33% of males). The percentage of intersex fish per site was 8-91% for largemouth bass and 14-73% for smallmouth bass. The incidence of intersex was greatest in the southeastern United States, with intersex largemouth bass present at all sites in the Apalachicola, Savannah, and Pee Dee River Basins. Total mercury, trans-nonachlor, p,p???-DDE, p,p???-DDD, and total PCBs were the most commonly detected chemical contaminants at all sites, regardless of whether intersex was observed. Although the genotype of the intersex fish was not determined, the microscopic appearance of the gonads, the presence of mature sperm, and the concentrations of sex steroid hormones and vitellogenin indicate the intersex bass were males. Few reproductive endpoints differed significantly among male and intersex bass; plasma vitellogenin concentration in males was not a good indicator of intersex presence. Hierarchical linkages of the intersex condition to reproductive function will require a more quantitative measure of intersex (e.g. severity index) rather than presence or absence of the condition. The baseline incidence of intersex gonadal tissue in black basses and other freshwater fishes is unknown, but intersex prevalence may be related to collection season, age, and endocrine active compounds in the environment. Intersex was not found in largemouth bass older than five years and was most common in 1-3-year-old male largemouth bass. The cause(s) of intersex in these species is also unknown, and it remains to be determined whether the intersex we observed in largemouth and smallmouth bass developed during sex differentiation in early life stages, during exposure to environmental factors during adult life stages, or both.","language":"English","publisherLocation":"Elsevier","doi":"10.1016/j.aquatox.2009.08.001","issn":"0166445X","usgsCitation":"Hinck, J., Blazer, V., Schmitt, C., Papoulias, D., and Tillitt, D.E., 2009, Widespread occurrence of intersex in black basses (Micropterus spp.) from U.S. rivers, 1995-2004: Aquatic Toxicology, v. 95, no. 1, p. 60-70, https://doi.org/10.1016/j.aquatox.2009.08.001.","productDescription":"11 p.","startPage":"60","endPage":"70","costCenters":[{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":245129,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217203,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.aquatox.2009.08.001"}],"volume":"95","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bd0b4e4b08c986b32eff5","contributors":{"authors":[{"text":"Hinck, J.E.","contributorId":47560,"corporation":false,"usgs":true,"family":"Hinck","given":"J.E.","affiliations":[],"preferred":false,"id":460542,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blazer, V.

However, the use of a 500 m circle may seem counterintuitive given that contributing areas are expected to extend up-gradient from wells, and not be circular in shape. The objective of this study was to evaluate if a 500 m circle is adequate for assigning land use to a well for the statistical correlation between urban land use and the occurrence of volatile organic compounds (VOCs). Land use and VOC data came from 277 supply wells in four study areas in California. Land use was computed using ten different-sized circles and wedges (250 m to 10 km in radius), and three different-sized \"searchlights\" (1-2 km in length). We define these shapes as contributing area surrogates (CASs), recognizing that a simple shape is at best a surrogate for the actual contributing area. The presence or absence of correlation between land use and the occurrence of VOCs was evaluated using Kendall's tau (??). Values of ?? were within 10% of one another for wedges and circles ranging in size from 500 m to 2 km, with correlations remaining statistically significant (p < 0.05) for all CAS sizes and shapes, suggesting that a 500 m circular CAS is adequate for assigning land use to a well. Additional evaluation indicated that urban land use is autocorrelated at distances ranging from 8 to 36 km. Thus, urban land use in a 500 m CAS is likely to be predictive of urban land use in the actual contributing area.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2009.02.056","issn":"00221694","usgsCitation":"Johnson, T., and Belitz, K., 2009, Assigning land use to supply wells for the statistical characterization of regional groundwater quality: Correlating urban land use and VOC occurrence: Journal of Hydrology, v. 370, no. 1-4, p. 100-108, https://doi.org/10.1016/j.jhydrol.2009.02.056.","startPage":"100","endPage":"108","numberOfPages":"9","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":244780,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216882,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2009.02.056"}],"volume":"370","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ee8be4b0c8380cd49dea","contributors":{"authors":[{"text":"Johnson, T.D.","contributorId":32744,"corporation":false,"usgs":true,"family":"Johnson","given":"T.D.","email":"","affiliations":[],"preferred":false,"id":444986,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Belitz, K. 0000-0003-4481-2345","orcid":"https://orcid.org/0000-0003-4481-2345","contributorId":10164,"corporation":false,"usgs":true,"family":"Belitz","given":"K.","affiliations":[],"preferred":false,"id":444985,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70046644,"text":"70046644 - 2009 - Timber harvest change in the Little North Santiam River Basin, Oregon, 1995 to 2009","interactions":[],"lastModifiedDate":"2013-06-18T09:21:23","indexId":"70046644","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"title":"Timber harvest change in the Little North Santiam River Basin, Oregon, 1995 to 2009","docAbstract":"Using available aerial photos from approximately a 15-year period, changes in timber harvest were mapped in the Little North Santiam River Basin, Oregon.

The International Continental Scientific Drilling Program (ICDP)-U.S. Geological Survey (USGS) Eyreville drill cores from the Chesapeake Bay impact structure provide one of the most complete geologic sections ever obtained from an impact structure. This paper presents a series of geologic columns and descriptive lithologic information for the lower impactite and crystalline-rock sections in the cores. The lowermost cored section (1766-1551 m depth) is a complex assemblage of mica schists that commonly contain graphite and fibrolitic sillimanite, intrusive granite pegmatites that grade into coarse granite, and local zones of mylonitic deformation. This basement-derived section is variably overprinted by brittle cataclastic fabrics and locally cut by dikes of polymict impact breccia, including several suevite dikes. An overlying succession of suevites and lithic impact breccias (1551-1397 m) includes a lower section dominated by polymict lithic impact breccia with blocks (up to 17 m) and boulders of cataclastic gneiss and an upper section (above 1474 m) of suevites and clast-rich impact melt rocks. The uppermost suevite is overlain by 26 m (1397-1371 m) of gravelly quartz sand that contains an amphibolite block and boulders of cataclasite and suevite. Above the sand, a 275-m-thick allochthonous granite slab (1371-1096 m) includes gneissic biotite granite, fine- and medium-to-coarse-grained biotite granites, and red altered granite near the base. The granite slab is overlain by more gravelly sand, and both are attributed to debris-avalanche and/or rockslide deposition that slightly preceded or accompanied seawater-resurge into the collapsing transient crater.

Petrology and P–T estimates indicate that a magmatic epidote-bearing quartz diorite pluton from Mt. Gamsby, Coast Plutonic Complex, British Columbia, was sourced at pressures below ∼1.4 GPa and cooled nearly isobarically at ∼0.9 GPa. The P–T path indicates that the magma was within the stability field of magmatic epidote early and remained there upon final crystallization. The pluton formed and crystallized at depths greater than ∼30 km. REE data indicate that garnet was absent in the melting region and did not fractionate during crystallization. This suggests that the crust was less than or equal to ∼55 km thick at 188 Ma during the early phases of magmatism in the Coast Plutonic Complex. Late Cretaceous contractional deformation and early Tertiary extension exhumed the rocks to upper crustal levels. Textures of magmatic epidote and other magmatic phases, combined with REE data, can be important for constraining the P–T path followed by magmas.

Small mammals are rarely reported from subfossil sites in Madagascar despite their importance for paleoenvironmental reconstruction, especially as it relates to recent ecological changes on the island. We describe the uniquely rich subfossil small mammal fauna from Ankilitelo Cave, southwestern Madagascar. The Ankilitelo fauna is dated to the late Holocene (∼500 years ago), documenting the youngest appearances of the extinct giant lemur taxa Palaeopropithecus, Megaladapis, and Archaeolemur, in association with abundant remains of small vertebrates, including bats, tenrecs, carnivorans, rodents, and primates. The Ankilitelo fauna is composed of 34 mammalian species, making it one of the most diverse Holocene assemblages in Madagascar. The fauna comprises the 1st report of the short-tailed shrew tenrec (Microgale brevicaudata) and the ring-tailed mongoose (Galidia elegans) in southwestern Madagascar. Further, Ankilitelo documents the presence of southwestern species that are rare or that have greatly restricted ranges today, such as Nasolo's shrew tenrec (M. nasoloi), Grandidier's mongoose (Galidictis grandidieri), the narrow-striped mongoose (Mungotictis decemlineata), and the giant jumping rat (Hypogeomys antimena). A simple cause for the unusual small mammal occurrences at Ankilitelo is not obvious. Synergistic interactions between climate change, recent fragmentation and human-initiated degradation of forested habitats, and community-level processes, such as predation, most likely explain the disjunct distributions of the small mammals documented at Ankilitelo.

This mobility implies low effective moisture at the desert margin, in contrast to growing evidence for greater than modern monsoon precipitation at the same time in central and southern China. Dry conditions in the early Holocene at the desert margin can be explained through a dynamic link between enhanced diabatic heating in the core region of the strengthened monsoon and increased subsidence in drylands to the north, combined with high evapotranspiration rates due to high summer temperatures. After 8 ka ago, as the monsoon weakened and lower temperatures reduced evapotranspiration, eolian sands were stabilized by vegetation. Aridity and dune mobility at the desert margin and a strengthened monsoon can both be explained as responses to high summer insolation in the early Holocene. ?? 2009 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G30240A.1","issn":"00917613","usgsCitation":"Mason, J., Lu, H., Zhou, Y., Miao, X., Swinehart, J.B., Liu, Z., Goble, R., and Yi, S., 2009, Dune mobility and aridity at the desert margin of northern China at a time of peak monsoon strength: Geology, v. 37, no. 10, p. 947-950, https://doi.org/10.1130/G30240A.1.","startPage":"947","endPage":"950","numberOfPages":"4","costCenters":[],"links":[{"id":217151,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G30240A.1"},{"id":245072,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"37","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0416e4b0c8380cd50792","contributors":{"authors":[{"text":"Mason, J.A.","contributorId":31507,"corporation":false,"usgs":true,"family":"Mason","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":460897,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lu, H.","contributorId":49936,"corporation":false,"usgs":true,"family":"Lu","given":"H.","email":"","affiliations":[],"preferred":false,"id":460899,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zhou, Y.","contributorId":70526,"corporation":false,"usgs":true,"family":"Zhou","given":"Y.","email":"","affiliations":[],"preferred":false,"id":460901,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Miao, X.","contributorId":60753,"corporation":false,"usgs":true,"family":"Miao","given":"X.","email":"","affiliations":[],"preferred":false,"id":460900,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Swinehart, J.

Predictive models for fish assemblages were constructed to assess biological condition and changes in biodiversity for streams sampled in the eastern United States as part of the U.S. Geological Survey's National Water Quality Assessment Program. Separate predictive models were developed for northern and southern regions. Reference sites were designated using land cover and local professional judgment. Taxonomic completeness was quantified based on the ratio of the number of observed native fish species expected to occur to the number of expected native fish species. Models for both regions accurately predicted fish species composition at reference sites with relatively high precision and low bias. In general, species that occurred less frequently than expected (decreasers) tended to prefer riffle areas and larger substrates, such as gravel and cobble, whereas increaser species (occurring more frequently than expected) tended to prefer pools, backwater areas, and vegetated and sand substrates. In the north, the percentage of species identified as increasers and the percentage identified as decreasers were equal, whereas in the south nearly two-thirds of the species examined were identified as decreasers. Predictive models of fish species can provide a standardized indicator for consistent assessments of biological condition at varying spatial scales and critical information for an improved understanding of fish species that are potentially at risk of loss with changing water quality conditions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","doi":"10.1577/T08-132.1","usgsCitation":"Meador, M., and Carlisle, D.M., 2009, Predictive models for fish assemblages in eastern USA streams: implications for assessing biodiversity: Transactions of the American Fisheries Society, v. 138, no. 4, p. 725-740, https://doi.org/10.1577/T08-132.1.","productDescription":"16 p.","startPage":"725","endPage":"740","numberOfPages":"16","ipdsId":"IP-003386","costCenters":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"links":[{"id":272210,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272208,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/T08-132.1"}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -100.00,24.96 ], [ -100.00,48.97 ], [ -66.98,48.97 ], [ -66.98,24.96 ], [ -100.00,24.96 ] ] ] } } ] }","volume":"138","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-01-09","publicationStatus":"PW","scienceBaseUri":"53cd6c75e4b0b290851048f5","contributors":{"authors":[{"text":"Meador, Michael R. mrmeador@usgs.gov","contributorId":615,"corporation":false,"usgs":true,"family":"Meador","given":"Michael R.","email":"mrmeador@usgs.gov","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":477624,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carlisle, Daren M. 0000-0002-7367-348X dcarlisle@usgs.gov","orcid":"https://orcid.org/0000-0002-7367-348X","contributorId":513,"corporation":false,"usgs":true,"family":"Carlisle","given":"Daren","email":"dcarlisle@usgs.gov","middleInitial":"M.","affiliations":[{"id":503,"text":"Office of Water Quality","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":477623,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70034125,"text":"70034125 - 2009 - Experimental alteration of artificial and natural impact melt rock from the Chesapeake Bay impact structure","interactions":[],"lastModifiedDate":"2012-03-12T17:21:45","indexId":"70034125","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3459,"text":"Special Paper of the Geological Society of America","active":true,"publicationSubtype":{"id":10}},"title":"Experimental alteration of artificial and natural impact melt rock from the Chesapeake Bay impact structure","docAbstract":"The alteration or transformation of impact melt rock to clay minerals, particularly smectite, has been recognized in several impact structures (e.g., Ries, Chicxulub, Mj??lnir). We studied the experimental alteration of two natural impact melt rocks from suevite clasts that were recovered from drill cores into the Chesapeake Bay impact structure and two synthetic glasses. These experiments were conducted at hydrothermal temperature (265 ??C) in order to reproduce conditions found in meltbearing deposits in the first thousand years after deposition. The experimental results were compared to geochemical modeling (PHREEQC) of the same alteration and to original mineral assemblages in the natural melt rock samples. In the alteration experiments, clay minerals formed on the surfaces of the melt particles and as fine-grained suspended material. Authigenic expanding clay minerals (saponite and Ca-smectite) and vermiculite/chlorite (clinochlore) were identified in addition to analcime. Ferripyrophyllite was formed in three of four experiments. Comparable minerals were predicted in the PHREEQC modeling. A comparison between the phases formed in our experiments and those in the cores suggests that the natural alteration occurred under hydrothermal conditions similar to those reproduced in the experiment. ?? 2009 The Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/2009.2458(24)","issn":"00721077","usgsCitation":"Declercq, J., Dypvik, H., Aagaard, P., Jahren, J., Ferrell, R., and Horton, J., 2009, Experimental alteration of artificial and natural impact melt rock from the Chesapeake Bay impact structure: Special Paper of the Geological Society of America, no. 458, p. 559-569, https://doi.org/10.1130/2009.2458(24).","startPage":"559","endPage":"569","numberOfPages":"11","costCenters":[],"links":[{"id":244674,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216783,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/2009.2458(24)"}],"issue":"458","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0dbee4b0c8380cd53189","contributors":{"authors":[{"text":"Declercq, J.","contributorId":66514,"corporation":false,"usgs":true,"family":"Declercq","given":"J.","email":"","affiliations":[],"preferred":false,"id":444219,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dypvik, H.","contributorId":104299,"corporation":false,"usgs":true,"family":"Dypvik","given":"H.","affiliations":[],"preferred":false,"id":444220,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Aagaard, Per","contributorId":57690,"corporation":false,"usgs":false,"family":"Aagaard","given":"Per","email":"","affiliations":[{"id":24717,"text":"University of Oslo, Norway","active":true,"usgs":false}],"preferred":false,"id":444218,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jahren, J.","contributorId":18204,"corporation":false,"usgs":true,"family":"Jahren","given":"J.","email":"","affiliations":[],"preferred":false,"id":444216,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ferrell, R.E.

Kīlauea may be one of the world's most intensively monitored volcanoes, but its eruptive history over the past several thousand years remains rather poorly known. 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 TiO2 and K2O 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. 2009 Geological Society of America.

Concentrations of 31 metals, metalloids, and other elements were measured in insects and insectivorous bird tissues from three drainages with different geochemistry and mining histories in Summit Co., Colorado, in 2003, 2004, and 2005. In insect samples, all 25 elements that were analyzed in all years increased in both Snake and Deer Creeks in the mining impacted areas compared to areas above and below the mining impacted areas. This distribution of elements was predicted from known or expected sediment contamination resulting from abandoned mine tailings in those drainages. Element concentrations in avian liver tissues were in concordance with levels in insects, that is with concentrations higher in mid-drainage areas where mine tailings were present compared to both upstream and downstream locations; these differences were not always statistically different, however. The lack of statistically significant differences in liver tissues, except for a few elements, was due to relatively small sample sizes and because many of these elements are essential and therefore well regulated by the bird’s homeostatic processes. Most elements were at background concentrations in avian liver tissue except for Pb which was elevated at mid-drainage sites to levels where δ-aminolevulinic acid dehydratase activity was inhibited at other mining sites in Colorado. Lead exposure, however, was not at toxic levels. Fecal samples were not a good indication of what elements birds ingested and were potentially exposed to.

The primary goals of the strong motion instrumentation are to obtain strong earthquake shaking data for verifying seismic analysis procedures and strengthening schemes, and for post-earthquake evaluations of port structures. The wharves instrumented by CSMIP were recommended by the Strong Motion Instrumentation Advisory Committee, a committee of the California Seismic Safety Commission. Extensive instrumentation of a wharf is difficult and would be impossible without the cooperation of the owners and the involvement of the design engineers. The instrumentation plan for a wharf is developed through study of the retrofit plans of the wharf, and the strong-motion sensors are installed at locations where specific instrumentation objectives can be achieved and access is possible. Some sensor locations have to be planned during design; otherwise they are not possible to install after construction.

This project explored the effectiveness of using portable, water-filled cofferdams as a management tool to promote the natural growth of emergent vegetation from the seed bank in a Lake Erie coastal wetland. A series of dams stretching approximately 450??m was installed temporarily to isolate hydrologically a 10-ha corner of the Crane Creek wetland complex from Lake Erie. The test area was dewatered in 2004 to mimic a low-water year, and vegetation sampling characterized the wetland seed bank response at low, middle, and high elevations in areas open to and protected from bird and mammal herbivory. The nearly two-month drawdown stimulated a rapid seed-bank-driven response by 45 plant taxa. Herbivory had little effect on plant species richness, regardless of the location along an elevation gradient. Inundation contributed to the replacement of immature emergent plant species with submersed aquatic species after the dams failed and were removed prematurely. This study revealed a number of important issues that must be considered for effective long-term implementation of portable cofferdam technology to stimulate wetland seed banks, including duration of dewatering, product size, source of clean water, replacement of damaged dams, and regular maintenance. This technology is a potentially important tool in the arsenal used by resource managers seeking to rehabilitate the functions and values of Great Lakes coastal wetland habitats.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jglr.2008.12.005","issn":"03801330","usgsCitation":"Kowalski, K., Wilcox, D., and Wiley, M., 2009, Stimulating a Great Lakes coastal wetland seed bank using portable cofferdams: implications for habitat rehabilitation: Journal of Great Lakes Research, v. 35, no. 2, p. 206-214, https://doi.org/10.1016/j.jglr.2008.12.005.","startPage":"206","endPage":"214","numberOfPages":"9","costCenters":[],"links":[{"id":476526,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/20.500.12648/2292","text":"External Repository"},{"id":215386,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2008.12.005"},{"id":243185,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9840e4b08c986b31bf22","contributors":{"authors":[{"text":"Kowalski, K.P.","contributorId":8975,"corporation":false,"usgs":true,"family":"Kowalski","given":"K.P.","email":"","affiliations":[],"preferred":false,"id":449046,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilcox, D.A.","contributorId":55382,"corporation":false,"usgs":true,"family":"Wilcox","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":449047,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wiley, M.J.","contributorId":68976,"corporation":false,"usgs":true,"family":"Wiley","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":449048,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70034833,"text":"70034833 - 2009 - Symbiotic regulation of plant growth, development and reproduction","interactions":[],"lastModifiedDate":"2021-02-24T13:34:13.037425","indexId":"70034833","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1285,"text":"Communitative and Integrative Biology","active":true,"publicationSubtype":{"id":10}},"title":"Symbiotic regulation of plant growth, development and reproduction","docAbstract":"

The growth and development of rice (Oryzae sativa) seedlings was shown to be regulated epigenetically by a fungal endophyte. In contrast to un-inoculated (nonsymbiotic) plants, endophyte colonized (symbiotic) plants preferentially allocated resources into root growth until root hairs were well established. During that time symbiotic roots expanded at five times the rate observed in nonsymbiotic plants. Endophytes also influenced sexual reproduction of mature big sagebrush (Artemisia tridentata) plants. Two spatially distinct big sagebrush subspecies and their hybrids were symbiotic with unique fungal endophytes, despite being separated by only 380m distance and 60 m elevation. A double reciprocal transplant experiment of parental and hybrid plants, and soils across the hybrid zone showed that fungal endophytes interact with the soils and different plant genotypes to confer enhanced plant reproduction in soil native to the endophyte and reduced reproduction in soil alien to the endophyte. Moreover, the most prevalent endophyte of the hybrid zone reduced the fitness of both parental subspecies. Because these endophytes are passed to the next generation of plants on seed coats, this interaction provides a selective advantage, habitat specificity, and the means of restricting gene flow, thereby making the hybrid zone stable, narrow, and potentially leading to speciation.

The Pacific Ocean is particularly important in this respect because of its dominant role in exporting heat and moisture from the tropics to higher latitudes. Through targeting groundwaters in the Mojave Desert, California, we show that noble gas derived temperatures in California averaged 4.2 ?? 1.1 ??C cooler in the Late Pleistocene (from ???43 to ???12 ka) compared to the Holocene (from ???10 to ???5 ka). Furthermore, the older groundwaters contain higher concentrations of excess air (entrained air bubbles) and have elevated oxygen-18/oxygen-16 ratios (??18O) - indicators of vigorous aquifer recharge, and greater rainfall amounts and/or more intense precipitation events, respectively. Together, these paleoclimate indicators reveal that cooler and wetter conditions prevailed in the Mojave Desert from ???43 to ???12 ka.

Methods and Results: Drinking-water samples (100 l) were seeded with Bacillus anthracis, Cryptospordium parvum, Francisella tularensis, Salmonella Typhi, and Vibrio cholerae and concentrated by UF. Recoveries by traditional methods were variable between samples and between some replicates; recoveries were not determined by qPCR. Francisella tularensis and V. cholerae were detected in all 14 samples after UF, B. anthracis was detected in 13, and C. parvum was detected in 9 out of 14 samples. Numbers found by qPCR after UF were significantly or nearly related to those found by traditional methods for all organisms except for C. parvum. A qPCR assay for S. Typhi was not available. Conclusions: qPCR can be used to rapidly detect biological agents after UF as well as traditional methods, but additional work is needed to improve qPCR assays for several biological agents, determine recoveries by qPCR, and expand the study to other areas.

Information on instrumentation, fractionation processes, data-reporting terminology, and reference materials presented here will help the reader to better understand this rapidly evolving field.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Elements","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2113/gselements.5.6.349","issn":"18115209","usgsCitation":"Bullen, T., and Eisenhauer, A., 2009, Metal stable isotopes in low-temperature systems: A primer: Elements, v. 5, no. 6, p. 349-352, https://doi.org/10.2113/gselements.5.6.349.","startPage":"349","endPage":"352","numberOfPages":"4","costCenters":[],"links":[{"id":244006,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216157,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2113/gselements.5.6.349"}],"volume":"5","issue":"6","noUsgsAuthors":false,"publicationDate":"2009-12-28","publicationStatus":"PW","scienceBaseUri":"505a5484e4b0c8380cd6cfce","contributors":{"authors":[{"text":"Bullen, T.D.","contributorId":79911,"corporation":false,"usgs":true,"family":"Bullen","given":"T.D.","email":"","affiliations":[],"preferred":false,"id":451246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eisenhauer, A.","contributorId":101099,"corporation":false,"usgs":true,"family":"Eisenhauer","given":"A.","email":"","affiliations":[],"preferred":false,"id":451247,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70035340,"text":"70035340 - 2009 - Adoption in rock and white-tailed ptarmigan","interactions":[],"lastModifiedDate":"2012-03-12T17:21:55","indexId":"70035340","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3784,"text":"Wilson Journal of Ornithology","active":true,"publicationSubtype":{"id":10}},"title":"Adoption in rock and white-tailed ptarmigan","docAbstract":"Reports of adoption in birds are widespread, but few studies report rates of adoption or possible mechanisms for this phenomenon, particularly in the Order Galliformes. We report incidents of adoption in Rock Ptarmigan (Lagopus muta) and White-tailed Ptarmigan (L. leucura) from two sites in western Canada. Adoption rates for White-tailed Ptarmigan on Vancouver Island, British Columbia, and the Ruby Ranges, Yukon Territory were 13% (n = 16 broods) and 4% (n = 27), respectively, while rates for Rock Ptarmigan were 14% (n = 29) in the Ruby Ranges. Low brood densities may result in lower rates of adoption for ptarmigan. ?? 2009 The Wilson Ornithological Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Journal of Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1676/08-029.1","issn":"15594491","usgsCitation":"Wong, M., Fedy, B., Wilson, S., and Martin, K.M., 2009, Adoption in rock and white-tailed ptarmigan: Wilson Journal of Ornithology, v. 121, no. 3, p. 638-641, https://doi.org/10.1676/08-029.1.","startPage":"638","endPage":"641","numberOfPages":"4","costCenters":[],"links":[{"id":215312,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1676/08-029.1"},{"id":243107,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"121","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e6f9e4b0c8380cd4776a","contributors":{"authors":[{"text":"Wong, M.M.L.","contributorId":98967,"corporation":false,"usgs":true,"family":"Wong","given":"M.M.L.","email":"","affiliations":[],"preferred":false,"id":450270,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fedy, B.C.","contributorId":35427,"corporation":false,"usgs":true,"family":"Fedy","given":"B.C.","email":"","affiliations":[],"preferred":false,"id":450268,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wilson, S.","contributorId":98935,"corporation":false,"usgs":true,"family":"Wilson","given":"S.","affiliations":[],"preferred":false,"id":450269,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Martin, K.

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: Geobacter sulfurreducens, Shewanella oneidensis and Veillonella atypica: 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}]}} ]}
