Models were applied to a representative lotic fish species, the flathead catfish (Pylodictis olivaris), for which two populations were examined: a native population from a regulated reach of the Coosa River (Alabama, USA) and an introduced population from an unregulated section of the Ocmulgee River (Georgia, USA). Size-classified matrix models were constructed for both populations, and residuals from catch-curve regressions were used as indices of year class strength (i.e., recruitment). A multiple regression model indicated that recruitment of flathead catfish in the Coosa River was positively related to the frequency of spring pulses between 283 and 566 m<sup>3</sup>/s. For the Ocmulgee River population, multiple regression models indicated that year class strength was negatively related to mean March discharge and positively related to June low flow. When the Coosa population was modeled to experience five consecutive years of favorable hydrologic conditions during a 50-year projection period, it exhibited a substantial spike in size and increased at an overall 0.2% annual rate. When modeled to experience five years of unfavorable hydrologic conditions, the Coosa population initially exhibited a decrease in size but later stabilized and increased at a 0.4% annual rate following the decline. When the Ocmulgee River population was modeled to experience five years of favorable conditions, it exhibited a substantial spike in size and increased at an overall 0.4% annual rate. After the Ocmulgee population experienced five years of unfavorable conditions, a sharp decline in population size was predicted. However, the population quickly recovered, with population size increasing at a 0.3% annual rate following the decline. In general, stochastic population growth in the Ocmulgee River was more erratic and variable than population growth in the Coosa River. We encourage ecologists to develop similar models for other lotic species, particularly in regulated river systems. Successful management of fish populations in regulated systems requires that we are able to predict how hydrology affects recruitment and will ultimately influence the population dynamics of fishes. ?? 2010 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-0305.1","issn":"10510761","usgsCitation":"Sakaris, P., and Irwin, E., 2010, Tuning stochastic matrix models with hydrologic data to predict the population dynamics of a riverine fish: Ecological Applications, v. 20, no. 2, p. 483-496, https://doi.org/10.1890/08-0305.1.","startPage":"483","endPage":"496","numberOfPages":"14","costCenters":[],"links":[{"id":216999,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-0305.1"},{"id":244907,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb8eae4b08c986b327b17","contributors":{"authors":[{"text":"Sakaris, P.C.","contributorId":18954,"corporation":false,"usgs":true,"family":"Sakaris","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":460314,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Irwin, E.R.","contributorId":90269,"corporation":false,"usgs":true,"family":"Irwin","given":"E.R.","email":"","affiliations":[],"preferred":false,"id":460315,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The refugial hypothesis argues that populations retracted during glacial maxima and were isolated in separate refugia. One prediction of this hypothesis is that populations inhabiting different refugia diverged and then, during interglacial periods, rapidly expanded into deglaciated regions. The range of the gray wolf (Canis lupus) was modified by these expansion and contraction cycles in the late Pleistocene. Our analyses of variation of mitochondrial control region sequences corroborate previous microsatellite analyses supporting independent evolutionary histories for Coastal and Continental wolves in North America. Coastal wolves represent the remnants of a formerly widespread and diverse southern clade that expanded into coastal Southeast Alaska, likely in the early Holocene. In contrast, extant northern Continental populations appear to be admixed, composed of lineages independently arising from ancestors that persisted in either southern or northern (Beringia) refugia. This pattern of diversification suggests the possibility of 3 temporally independent colonizations of North America by wolves from Asia. Coastal wolves are the last vestige of a formerly widespread phylogroup that largely was extirpated in North America by humans during the last century. The independent phylogeographic history of these Coastal wolves has yet to be characterized. Their distinctiveness among North American wolf populations may warrant a reevaluation of their conservation status and management. ?? 2009 American Society of Mammalogists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1644/09-MAMM-A-036.1","issn":"00222372","usgsCitation":"Weckworth, B.V., Talbot, S.L., and Cook, J.A., 2010, Phylogeography of wolves (Canis lupus) in the Pacific Northwest: Journal of Mammalogy, v. 91, no. 2, p. 363-375, https://doi.org/10.1644/09-MAMM-A-036.1.","startPage":"363","endPage":"375","numberOfPages":"13","costCenters":[],"links":[{"id":475919,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1644/09-mamm-a-036.1","text":"Publisher Index Page"},{"id":244949,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217038,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/09-MAMM-A-036.1"}],"volume":"91","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7a62e4b0c8380cd78e9b","contributors":{"authors":[{"text":"Weckworth, Byron V.","contributorId":195766,"corporation":false,"usgs":false,"family":"Weckworth","given":"Byron","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":461234,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Talbot, Sandra L. 0000-0002-3312-7214 stalbot@usgs.gov","orcid":"https://orcid.org/0000-0002-3312-7214","contributorId":140512,"corporation":false,"usgs":true,"family":"Talbot","given":"Sandra","email":"stalbot@usgs.gov","middleInitial":"L.","affiliations":[{"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":461235,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cook, Joseph A.","contributorId":8323,"corporation":false,"usgs":false,"family":"Cook","given":"Joseph","email":"","middleInitial":"A.","affiliations":[{"id":7000,"text":"Department of Biology, University of New Mexico","active":true,"usgs":false}],"preferred":false,"id":461236,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although the monophyly of a 'core' wood-warbler clade is well established, no phylogenetic hypothesis for this group has included a full sampling of wood-warbler species diversity. We used parsimony, maximum likelihood, and Bayesian methods to reconstruct relationships among all genera and nearly all wood-warbler species, based on a matrix of mitochondrial DNA (5840 nucleotides) and nuclear DNA (6 loci, 4602 nucleotides) characters. The resulting phylogenetic hypotheses provide a highly congruent picture of wood-warbler relationships, and indicate that the traditional generic classification of these birds recognizes many non-monophyletic groups. We recommend a revised taxonomy in which each of 14 genera (Seiurus, Helmitheros, Mniotilta, Limnothlypis, Protonotaria, Parkesia, Vermivora, Oreothlypis, Geothlypis, Setophaga, Myioborus, Cardellina, Basileuterus, Myiothlypis) corresponds to a well-supported clade; these nomenclatural changes also involve subsuming a number of well-known, traditional wood-warbler genera (Catharopeza, Dendroica, Ergaticus, Euthlypis, Leucopeza, Oporornis, Parula, Phaeothlypis, Wilsonia). We provide a summary phylogenetic hypothesis that will be broadly applicable to investigations of the historical biogeography, processes of diversification, and evolution of trait variation in this well studied avian group. ?? 2010 Elsevier Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Molecular Phylogenetics and Evolution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ympev.2010.07.018","issn":"10557903","usgsCitation":"Lovette, I., Perez-Eman, J., Sullivan, J., Banks, R., Fiorentino, I., Cordoba-Cordoba, S., Echeverry-Galvis, M., Barker, F., Burns, K., Klicka, J., Lanyon, S.M., and Bermingham, E., 2010, A comprehensive multilocus phylogeny for the wood-warblers and a revised classification of the Parulidae (Aves): Molecular Phylogenetics and Evolution, v. 57, no. 2, p. 753-770, https://doi.org/10.1016/j.ympev.2010.07.018.","startPage":"753","endPage":"770","numberOfPages":"18","costCenters":[],"links":[{"id":218003,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ympev.2010.07.018"},{"id":245978,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"57","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e384e4b0c8380cd4609f","contributors":{"authors":[{"text":"Lovette, I.J.","contributorId":19252,"corporation":false,"usgs":true,"family":"Lovette","given":"I.J.","email":"","affiliations":[],"preferred":false,"id":461465,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Perez-Eman, J.

The analysis estimates that terrestrial areas of the Arctic Basin lost 62.9 Tg C yr<sup>-1</sup> and that the Arctic Ocean gained 94.1 Tg C yr<sup>-1</sup>. Arctic lands and oceans were a net CO<sub>2</sub> sink of 108.9 Tg C yr<sup>-1</sup>, which is within the range of uncertainty in estimates from atmospheric inversions. Although both lands and oceans of the Arctic were estimated to be CO<sub>2</sub> sinks, the land sink diminished in strength because of increased fire disturbance compared to previous decades, while the ocean sink increased in strength because of increased biological pump activity associated with reduced sea ice cover. Terrestrial areas of the Arctic were a net source of 41.5 Tg CH<sub>4</sub> yr<sup>-1</sup> that increased by 0.6 Tg CH<sub>4</sub> yr<sup>-1</sup> during the decade of analysis, a magnitude that is comparable with an atmospheric inversion of CH<sub>4</sub>. Because the radiative forcing of the estimated CH<sub>4</sub> emissions is much greater than the CO<sub>2</sub> sink, the analysis suggests that the Arctic Basin is a substantial net source of green house gas forcing to the climate system.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Tellus, Series B: Chemical and Physical Meteorology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Munksgaard","publisherLocation":"Copenhagen","doi":"10.1111/j.1600-0889.2010.00497.x","issn":"02806509","usgsCitation":"McGuire, A., Hayes, D., Kicklighter, D., Manizza, M., Zhuang, Q., Chen, M., Follows, M., Gurney, K., McClelland, J., Melillo, J.M., Peterson, B.J., and Prinn, R., 2010, An analysis of the carbon balance of the Arctic Basin from 1997 to 2006: Tellus, Series B: Chemical and Physical Meteorology, v. 62, no. 5, p. 455-474, https://doi.org/10.1111/j.1600-0889.2010.00497.x.","productDescription":"20 p.","startPage":"455","endPage":"474","numberOfPages":"20","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":475908,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1600-0889.2010.00497.x","text":"Publisher Index Page"},{"id":217985,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1600-0889.2010.00497.x"},{"id":245960,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Arctic Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -299.53125,\n              60.23981116999893\n            ],\n            [\n              -299.53125,\n              84.95930495623836\n            ],\n            [\n              85.078125,\n              84.95930495623836\n            ],\n            [\n              85.078125,\n              60.23981116999893\n            ],\n            [\n              -299.53125,\n              60.23981116999893\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"62","issue":"5","noUsgsAuthors":false,"publicationDate":"2010-01-01","publicationStatus":"PW","scienceBaseUri":"5059e9f4e4b0c8380cd48550","contributors":{"authors":[{"text":"McGuire, A.

The importance of developing a rigorous sampling design tailored to specific questions has already been discussed in the ecological and sampling literature and has provided useful tools and recommendations to sample and analyse ecological data. However, sampling issues are often difficult to overcome in ecological studies due to apparent inconsistencies between theory and practice, often leading to the implementation of simplified sampling designs that suffer from unknown biases. Moreover, we believe that classical sampling principles which are based on estimation of means and variances are insufficient to fully address many ecological questions that rely on estimating relationships between a response and a set of predictor variables over time and space. Our objective is thus to highlight the importance of selecting an appropriate sampling space and an appropriate sampling design. We also emphasize the importance of using prior knowledge of the study system to estimate models or complex parameters and thus better understand ecological patterns and processes generating these patterns. Using a semi-virtual simulation study as an illustration we reveal how the selection of the space (e.g. geographic, climatic), in which the sampling is designed, influences the patterns that can be ultimately detected. We also demonstrate the inefficiency of common sampling designs to reveal response curves between ecological variables and climatic gradients. Further, we show that response-surface methodology, which has rarely been used in ecology, is much more efficient than more traditional methods. Finally, we discuss the use of prior knowledge, simulation studies and model-based designs in defining appropriate sampling designs. We conclude by a call for development of methods to unbiasedly estimate nonlinear ecologically relevant parameters, in order to make inferences while fulfilling requirements of both sampling theory and field work logistics. ?? 2010 The Authors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1600-0587.2010.06421.x","issn":"09067590","usgsCitation":"Albert, C., Yoccoz, N.G., Edwards, T., Graham, C., Zimmermann, N., and Thuiller, W., 2010, Sampling in ecology and evolution - bridging the gap between theory and practice: Ecography, v. 33, no. 6, p. 1028-1037, https://doi.org/10.1111/j.1600-0587.2010.06421.x.","startPage":"1028","endPage":"1037","numberOfPages":"10","costCenters":[],"links":[{"id":218236,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1600-0587.2010.06421.x"},{"id":246228,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"33","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-12-09","publicationStatus":"PW","scienceBaseUri":"505ab084e4b0c8380cd87b4c","contributors":{"authors":[{"text":"Albert, C.H.","contributorId":50765,"corporation":false,"usgs":true,"family":"Albert","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":456478,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yoccoz, Nigel G.","contributorId":61537,"corporation":false,"usgs":true,"family":"Yoccoz","given":"Nigel","email":"","middleInitial":"G.","affiliations":[{"id":33046,"text":"Norwegian Institute for Nature Research","active":true,"usgs":false}],"preferred":false,"id":456479,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Edwards, T.C.","contributorId":72163,"corporation":false,"usgs":true,"family":"Edwards","given":"T.C.","email":"","affiliations":[],"preferred":false,"id":456480,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Graham, C.H.","contributorId":86611,"corporation":false,"usgs":true,"family":"Graham","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":456482,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Zimmermann, N.E.","contributorId":24547,"corporation":false,"usgs":true,"family":"Zimmermann","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":456477,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Thuiller, W.","contributorId":73034,"corporation":false,"usgs":true,"family":"Thuiller","given":"W.","affiliations":[],"preferred":false,"id":456481,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

It takes place as a result of the discovery of new pools/reservoirs and extensions of known pools within existing fields, improved knowledge of reservoirs over time leading to a change in estimates of original oil-in-place, and improvement in recovery factor through the application of new technology, such as enhanced oil recovery methods, horizontal/multilateral drilling, and 4D seismic. A reserve growth study was conducted on oil pools in Alberta, Canada, with the following objectives: 1) evaluate historical oil reserve data in order to assess the potential for future reserve growth; 2) develop reserve growth models/ functions to help forecast hydrocarbon volumes; 3) study reserve growth sensitivity to various parameters (for example, pool size, porosity, and oil gravity); and 4) compare reserve growth in oil pools and fields in Alberta with those from other large petroleum provinces around the world. The reported known recoverable oil exclusive of Athabasca oil sands in Alberta increased from 4.5 billion barrels of oil (BBO) in 1960 to 17 BBO in 2005. Some of the pools that were included in the existing database were excluded from the present study for lack of adequate data. Therefore, the known recoverable oil increased from 4.2 to 13.9 BBO over the period from 1960 through 2005, with new discoveries contributing 3.7 BBO and reserve growth adding 6 BBO. This reserve growth took place mostly in pools with more than 125,000 barrels of known recoverable oil. Pools with light oil accounted for most of the total known oil volume, therefore reflecting the overall pool growth. Smaller pools, in contrast, shrank in their total recoverable volumes over the years. Pools with heavy oil (gravity less than 20o API) make up only a small share (3.8 percent) of the total recoverable oil; they showed a 23-fold growth compared to about 3.5-fold growth in pools with medium oil and 2.2-fold growth in pools with light oil over a fifty-year period. The analysis indicates that pools with high porosity reservoirs (greater than 30 percent porosity) grew more than pools with lower porosity reservoirs which could possibly be attributed to permeability differences between the two types. Reserve growth models for Alberta, Canada, show the growth at field level is almost twice as much as at pool level, possibly because the analysis has evaluated fields with two or more pools with different discovery years. Based on the models, the growth in oil volumes in Alberta pools over the next five-year period (2006-2010) is expected to be about 454 million barrels of oil. Over a twenty-five year period, the cumulative reserve growth in Alberta oil pools has been only 2-fold compared to a 4- to- 5-fold increase in other petroleum producing areas such as Saskatchewan, Volga-Ural, U.S. onshore fields, and U.S. Gulf of Mexico. However, the growth at the field level compares well with that of U.S. onshore fields. In other petroleum provinces, the reserves are reported at field levels rather than at pool levels, the latter basically being the equivalent of individual reservoirs. ?? 2010 by the Canadian Society of Petroleum Geologists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Canadian Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2113/gscpgbull.58.3.283","issn":"00074802","usgsCitation":"Verma, M., and Cook, T., 2010, Reserve growth in oil pools of Alberta: Model and forecast: Bulletin of Canadian Petroleum Geology, v. 58, no. 3, p. 283-293, https://doi.org/10.2113/gscpgbull.58.3.283.","startPage":"283","endPage":"293","numberOfPages":"11","costCenters":[],"links":[{"id":218209,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2113/gscpgbull.58.3.283"},{"id":246196,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"58","issue":"3","noUsgsAuthors":false,"publicationDate":"2011-01-24","publicationStatus":"PW","scienceBaseUri":"505aa94ce4b0c8380cd85d1b","contributors":{"authors":[{"text":"Verma, M.","contributorId":72237,"corporation":false,"usgs":true,"family":"Verma","given":"M.","email":"","affiliations":[],"preferred":false,"id":456475,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cook, T.","contributorId":59991,"corporation":false,"usgs":true,"family":"Cook","given":"T.","affiliations":[],"preferred":false,"id":456474,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We experimentally quantified the effects of central stoneroller minnows (Campostoma anomalum (Rafinesque) and Meek's crayfish (Orconectes meeki meeki (Faxon)) on benthic communities using electric exclusion quadrats in Little Mulberry Creek before (June) and during (August) seasonal stream drying. Unglazed ceramic tiles were deployed in June and August to measure periphyton and invertebrate abundance, and leafpack decomposition and primary production were also measured in August. Relationships between stoneroller and crayfish density and the size of consumer effects were evaluated with multiple linear regression models. Average chlorophyll a abundance was greater on exposed than exclusion tiles in August, but not in June. Sediment dry mass, periphyton ash-free dry mass (AFDM), and chironomid densities on tiles did not differ among treatments in either period. Leaf packs decayed faster in exposed than exclusion treatments (k<sub>exposed</sub> = 0.038 ?? 0.013, k<sub>exclusion</sub> = 0.007 ?? 0.002), but consumer effects were stronger in some pools than others. Leafpack invertebrate biomass and abundance and tile primary productivity did not differ among treatments. Consumer effects on chlorophyll a were related to crayfish and stoneroller density, and effects on chironomid density were related to stoneroller density. These results contrast with a previous exclusion experiment in Little Mulberry Creek that demonstrated strong consumer effects. The influence of stream drying on consumer effects appears to have been reduced by strong spates, underscoring the importance of conducting multi-year studies to determine the magnitude of variability in ecological interactions. ??

Such wetlands reflect humid to perhumid climate, leading to characterizations of Pennsylvanian tropics as everwet, swampy. These views are biased by the high preservation potential of wetlands. Sedimentation patterns, paleosols, and fossil floras indicate the presence of vegetation tolerant of subhumid to dry-subhumid, perhaps semi-arid climate in basins between peat formation times. Understanding the significance of this seasonally-dry vegetation has suffered from conceptual and terminological confusion. A clearer view has emerged as models for framing the data have improved. Basinal floras typical of seasonally-dry conditions, relatively low soil moisture regimes, are well documented but mainly from isolated deposits. Some of the earliest, dominated by primitive pteridosperms (\"Fl??zfern\" floras), occur in clastic rocks between European Early Pennsylvanian coal beds. Later Early Pennsylvanian, fern-cordaitalean vegetation, different from coal floras, is preserved in marine goniatite bullions. Conifers are first suggested by late Mississippian Potoniesporites pollen. About the same time, in North America, broadleaf foliage, Lesleya and Megalopteris occur in basin-margin settings, on drought-prone limestone substrates. The best known, xeromorphic floras found between coal beds appear in the Middle through Late Pennsylvanian, containing conifers, cordaitaleans, and pteridosperms. The Middle Pennsylvanian appearances of this flora are mainly allochthonous, though parautochthonous occurrences have been reported. Parautochthonous assemblages are mostly Late Pennsylvanian. The conifer flora became dominant in western and central Pangaean equatorial lowlands in earliest Permian. Location of the humid-perhumid wetland flora during periods of relative dryness, though rarely discussed, is as, or more, perplexing than the spatial location of seasonally-dry floras through time - wetland plants had few migratory options and possibly survived in small refugia, within and outside of basins. Coupled oscillations in climate, sea level, and vegetation were driven most likely by glacial-interglacial fluctuations, perhaps controlled by orbital cyclicity. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal of Coal Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.coal.2010.01.007","issn":"01665162","usgsCitation":"DiMichele, W.A., Cecil, C.B., Montanez, I., and Falcon-Lang, H.J., 2010, Cyclic changes in Pennsylvanian paleoclimate and effects on floristic dynamics in tropical Pangaea: International Journal of Coal Geology, v. 83, no. 2-3, p. 329-344, https://doi.org/10.1016/j.coal.2010.01.007.","startPage":"329","endPage":"344","numberOfPages":"16","costCenters":[],"links":[{"id":217029,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.coal.2010.01.007"},{"id":244940,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fd22e4b0c8380cd4e658","contributors":{"authors":[{"text":"DiMichele, William A.","contributorId":97631,"corporation":false,"usgs":true,"family":"DiMichele","given":"William","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":460325,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cecil, C.

Surficial sediment was collected in 2003 from 29 sites along five streams with watersheds that extend from the core of the metropolitan area to its development fringe. Sediment was analyzed for 16 polycyclic aromatic hydrocarbons (PAHs), 3 common polychlorinated biphenyl mixtures (Aroclors), and 25 pesticide-related compounds of eight chemical classes. Multiple PAHs were detected at more than 50% of the sites, and concentrations of total PAHs ranged from 290 to 82,150&nbsp;μg/kg (dry weight). The concentration and frequency of detection of PAHs increased with increasing urbanization of the residential watersheds. Four- and five-ring PAH compounds predominated the PAH composition (73–100%), especially fluoranthene and pyrene. The PAH composition profiles along with the diagnostic isomer ratios [e.g., anthracene/(anthracene&nbsp;+&nbsp;phenanthrene), 0.16&nbsp;±&nbsp;0.03; fluoranthene/(fluoranthene&nbsp;+&nbsp;pyrene), 0.55&nbsp;±&nbsp;0.01)] indicate that pyrogenic sources (i.e., coal-tar-related operations or materials and traffic-related particles) may be common PAH contributors to these residential streams. Historical-use organochlorine insecticides and their degradates dominated the occurrences of pesticide-related compounds, with chlordane and dieldrin detected in over or nearly 50% of the samples. The occurrence of these historical organic compounds was associated with past urban applications, which may continue to be nonpoint sources replenishing local streams. Concentrations of low molecular weight (LMW; two or three rings) and high molecular weight (HMW; four to six rings) PAHs covaried along individual streams but showed dissimilar distribution patterns between the streams, while the historical pesticide-related compounds generally increased in concentration downstream. Correlations were noted between LMW and HMW PAHs for most of the streams and between historical-use organochlorine compounds and total organic carbon and clay content of sediments for one of the streams (Brush Creek). Stormwater runoff transport modes are proposed to describe how the two groups of contaminants migrated and distributed in the streambed.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s00244-010-9497-2","issn":"00904341","usgsCitation":"Tao, J., Huggins, D., Welker, G., Dias, J., Ingersoll, C.G., and Murowchick, J., 2010, Sediment contamination of residential streams in the metropolitan Kansas City area, USA: Part I. distribution of polycyclic aromatic hydrocarbon and pesticide-related compounds: Archives of Environmental Contamination and Toxicology, v. 59, no. 3, p. 352-369, https://doi.org/10.1007/s00244-010-9497-2.","productDescription":"18 p.","startPage":"352","endPage":"369","numberOfPages":"18","costCenters":[{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":218081,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00244-010-9497-2"},{"id":246062,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Kansas, Missouri","city":"Kansas City","volume":"59","issue":"3","noUsgsAuthors":false,"publicationDate":"2010-04-14","publicationStatus":"PW","scienceBaseUri":"505b8966e4b08c986b316dc6","contributors":{"authors":[{"text":"Tao, J.","contributorId":56485,"corporation":false,"usgs":true,"family":"Tao","given":"J.","email":"","affiliations":[],"preferred":false,"id":462235,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Huggins, D.","contributorId":29250,"corporation":false,"usgs":true,"family":"Huggins","given":"D.","email":"","affiliations":[],"preferred":false,"id":462232,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Welker, G.","contributorId":21390,"corporation":false,"usgs":true,"family":"Welker","given":"G.","email":"","affiliations":[],"preferred":false,"id":462231,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dias, J.R.","contributorId":97748,"corporation":false,"usgs":true,"family":"Dias","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":462236,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ingersoll, Christopher G. 0000-0003-4531-5949 cingersoll@usgs.gov","orcid":"https://orcid.org/0000-0003-4531-5949","contributorId":2071,"corporation":false,"usgs":true,"family":"Ingersoll","given":"Christopher","email":"cingersoll@usgs.gov","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":462234,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Murowchick, J.B.","contributorId":45058,"corporation":false,"usgs":true,"family":"Murowchick","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":462233,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Hydrologic alteration has impaired riverine ecosystems on a global scale, and the pace and intensity of human development greatly exceeds the ability of scientists to assess the effects on a river-by-river basis. Current scientific understanding of hydrologic controls on riverine ecosystems and experience gained from individual river studies support development of environmental flow standards at the regional scale. 2. This paper presents a consensus view from a group of international scientists on a new framework for assessing environmental flow needs for many streams and rivers simultaneously to foster development and implementation of environmental flow standards at the regional scale. This framework, the ecological limits of hydrologic alteration (ELOHA), is a synthesis of a number of existing hydrologic techniques and environmental flow methods that are currently being used to various degrees and that can support comprehensive regional flow management. The flexible approach allows scientists, water-resource managers and stakeholders to analyse and synthesise available scientific information into ecologically based and socially acceptable goals and standards for management of environmental flows. 3. The ELOHA framework includes the synthesis of existing hydrologic and ecological databases from many rivers within a user-defined region to develop scientifically defensible and empirically testable relationships between flow alteration and ecological responses. These relationships serve as the basis for the societally driven process of developing regional flow standards. This is to be achieved by first using hydrologic modelling to build a 'hydrologic foundation' of baseline and current hydrographs for stream and river segments throughout the region. Second, using a set of ecologically relevant flow variables, river segments within the region are classified into a few distinctive flow regime types that are expected to have different ecological characteristics. These river types can be further subclassified according to important geomorphic features that define hydraulic habitat features. Third, the deviation of current-condition flows from baseline-condition flow is determined. Fourth, flow alteration-ecological response relationships are developed for each river type, based on a combination of existing hydroecological literature, expert knowledge and field studies across gradients of hydrologic alteration. 4. Scientific uncertainty will exist in the flow alteration-ecological response relationships, in part because of the confounding of hydrologic alteration with other important environmental determinants of river ecosystem condition (e.g. temperature). Application of the ELOHA framework should therefore occur in a consensus context where stakeholders and decision-makers explicitly evaluate acceptable risk as a balance between the perceived value of the ecological goals, the economic costs involved and the scientific uncertainties in functional relationships between ecological responses and flow alteration. 5. The ELOHA framework also should proceed in an adaptive management context, where collection of monitoring data or targeted field sampling data allows for testing of the proposed flow alteration-ecological response relationships. This empirical validation process allows for a fine-tuning of environmental flow management targets. The ELOHA framework can be used both to guide basic research in hydroecology and to further implementation of more comprehensive environmental flow management of freshwater sustainability on a global scale. ?? 2009 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2427.2009.02204.x","issn":"00465070","usgsCitation":"Poff, N., Richter, B.D., Arthington, A., Bunn, S., Naiman, R., Kendy, E., Acreman, M., Apse, C., Bledsoe, B., Freeman, M.C., Henriksen, J., Jacobson, R., Kennen, J., Merritt, D., O’Keeffe, J.H., Olden, J., Rogers, K., Tharme, R., and Warner, A., 2010, The ecological limits of hydrologic alteration (ELOHA): A new framework for developing regional environmental flow standards: Freshwater Biology, v. 55, no. 1, p. 147-170, https://doi.org/10.1111/j.1365-2427.2009.02204.x.","startPage":"147","endPage":"170","numberOfPages":"24","costCenters":[],"links":[{"id":475809,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1111/j.1365-2427.2009.02204.x","text":"External Repository"},{"id":216694,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2427.2009.02204.x"},{"id":244580,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"55","issue":"1","noUsgsAuthors":false,"publicationDate":"2009-12-15","publicationStatus":"PW","scienceBaseUri":"505baaf9e4b08c986b322b29","contributors":{"authors":[{"text":"Poff, N.L.","contributorId":22723,"corporation":false,"usgs":true,"family":"Poff","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":444503,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Richter, B.

We used historic and recent data on unionids (from 1987 to 2003) and hydraulic conditions at 438 sample locations over a 38-km reach of the Upper Mississippi River (Navigation Pool 8) to compare the distribution of unionids with different shell morphologies. We evaluated whether sculptured, thick-shelled (STK) species would be found in areas with higher velocity and shear stress, compared to nonsculptured, thin-shelled (NSTN) species. We used classification trees to model the presence and absence of STK and NSTN species to determine which variables were most likely to predict their distribution. Candidate predictor variables included sampling gear, field substrate, water depth (bathymetry), slope, velocity, shear stress and Froude number under low, moderate and high discharges. Our models predicted that STK mussels would occupy a larger portion of the total aquatic area in this reach of the river than NSTN mussels. However, our data demonstrated that NSTN species used areas of higher shear stress and velocity than STK species, but were also present in backwaters with low energy, thus rejecting our hypothesis. The presence of NSTN species over a wide range of shear stress and velocity was probably due to the wide array of life histories displayed within this guild. Overall, these results are consistent with the flow refuge concept in which unionids are more prevalent in areas with low to moderate hydraulic stresses, regardless of shell morphology, and demonstrate the importance of incorporating abiotic and biotic variables into predictive models.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Molluscan Studies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1093/mollus/eyp045","issn":"02601230","usgsCitation":"Bartsch, M., Zigler, S.J., Newton, T., and Sauer, J., 2010, Influence of shell morphology on distributions of unionids in the upper Mississippi River: Journal of Molluscan Studies, v. 76, no. 1, p. 67-76, https://doi.org/10.1093/mollus/eyp045.","startPage":"67","endPage":"76","numberOfPages":"10","costCenters":[],"links":[{"id":475945,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/mollus/eyp045","text":"Publisher Index Page"},{"id":216759,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1093/mollus/eyp045"},{"id":244646,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"76","issue":"1","noUsgsAuthors":false,"publicationDate":"2009-09-29","publicationStatus":"PW","scienceBaseUri":"505a3b7be4b0c8380cd62580","contributors":{"authors":[{"text":"Bartsch, M.R.","contributorId":42908,"corporation":false,"usgs":true,"family":"Bartsch","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":444532,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zigler, S.

During European colonization through the present, the UMRS has been modified to meet multiple demands such as navigation and flood control. Invasive species, notably the common carp, have dominated fisheries in both positive and negative ways. Through time, environmental decline plus reduced economic incentives have degraded opportunities for fishery production. A renewed focus on fisheries in the UMRS may be dawning. Commercial harvest and corresponding economic value of native and non-native species along the river corridor fluctuates but appears to be increasing. Recreational use will depend on access and societal perceptions of the river. Interactions (e. g., disease and invasive species transmission) among fish assemblages within the UMRS, the Great Lakes, and other lakes and rivers are rising. Data collection for fisheries has varied in intensity and contiguousness through time, although resources for research and management may be growing. As fisheries production likely relies on the interconnectivity of fish populations and associated ecosystem processes among river reaches (e. g., between the pooled and unpooled UMRS), species-level processes such as genetics, life-history interactions, and migratory behavior need to be placed in the context of broad ecosystem- and landscape-scale restoration. Formal communication among a diverse group of researchers, managers, and public stakeholders crossing geographic and disciplinary boundaries is necessary through peer-reviewed publications, moderated interactions, and the embrace of emerging information technologies. ??

The understanding of these near-surface processes is relevant to issues of runoff generation, groundwater-surface water interactions, catchment export of nutrients, dissolved organic carbon, contaminants (e.g. mercury) and ultimately surface water health. We develop a 3-D physics-based representation of the Panola Mountain Research Watershed experimental hillslope using the TOUGH2 sub-surface flow and transport simulator. A recent investigation of sub-surface flow within this experimental hillslope has generated important knowledge of threshold rainfall-runoff response and its relation to patterns of transient water table development. This work has identified components of the 3-D sub-surface, such as bedrock topography, that contribute to changing connectivity in saturated zones and the generation of sub-surface stormflow. Here, we test the ability of a 3-D hillslope model (both calibrated and uncalibrated) to simulate forested hillslope rainfall-runoff response and internal transient sub-surface stormflow dynamics. We also provide a transparent illustration of physics-based model development, issues of parameterization, examples of model rejection and usefulness of data types (e.g. runoff, mean soil moisture and transient water table depth) to the model enterprise. Our simulations show the inability of an uncalibrated model based on laboratory and field characterization of soil properties and topography to successfully simulate the integrated hydrological response or the distributed water table within the soil profile. Although not an uncommon result, the failure of the field-based characterized model to represent system behaviour is an important challenge that continues to vex scientists at many scales. We focus our attention particularly on examining the influence of bedrock permeability, soil anisotropy and drainable porosity on the development of patterns of transient groundwater and sub-surface flow. Internal dynamics of transient water table development prove to be essential in determining appropriate model parameterization. ?? 2010 John Wiley & Sons, Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrological Processes","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/hyp.7819","issn":"08856087","usgsCitation":"James, A., McDonnell, J.J., Tromp-Van Meerveld, I., and Peters, N., 2010, Gypsies in the palace: Experimentalist's view on the use of 3-D physics-based simulation of hillslope hydrological response: Hydrological Processes, v. 24, no. 26, p. 3878-3893, https://doi.org/10.1002/hyp.7819.","startPage":"3878","endPage":"3893","numberOfPages":"16","costCenters":[],"links":[{"id":241262,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213617,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/hyp.7819"}],"volume":"24","issue":"26","noUsgsAuthors":false,"publicationDate":"2010-12-10","publicationStatus":"PW","scienceBaseUri":"505a2e6be4b0c8380cd5c50d","contributors":{"authors":[{"text":"James, A.L.","contributorId":40710,"corporation":false,"usgs":true,"family":"James","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":437584,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McDonnell, Jeffery J. 0000-0002-3880-3162","orcid":"https://orcid.org/0000-0002-3880-3162","contributorId":62723,"corporation":false,"usgs":false,"family":"McDonnell","given":"Jeffery","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":437585,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tromp-Van Meerveld, I.","contributorId":103882,"corporation":false,"usgs":true,"family":"Tromp-Van Meerveld","given":"I.","email":"","affiliations":[],"preferred":false,"id":437586,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Peters, N.E.","contributorId":33332,"corporation":false,"usgs":true,"family":"Peters","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":437583,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Capture that results in a loss of water in streams, rivers, and wetlands now is a concern in many parts of the United States. Hydrologists commonly use analytical and numerical approaches to study temporal variations in sources of water to wells for select points of interest. Much can be learned about coupled surface/groundwater systems, however, by looking at the spatial distribution of theoretical capture for select times of interest. Development of maps of capture requires (1) a reasonably well-constructed transient or steady state model of an aquifer with head-dependent flow boundaries representing surface water features or evapotranspiration and (2) an automated procedure to run the model repeatedly and extract results, each time with a well in a different location. This paper presents new methods for simulating and mapping capture using three-dimensional groundwater flow models and presents examples from Arizona, Oregon, and Michigan.

This information is lacking for many ecosystems including the Sierra Nevada in California, USA. We investigated fuel deposition rates and stand characteristics of seven montane and four subalpine conifers in the Sierra Nevada. We collected foliage, miscellaneous bark and crown fragments, cones, and woody fuel classes from four replicate plots each in four stem diameter size classes for each species, for a total of 176 sampling sites. We used these data to develop predictive equations for each fuel class and diameter size class of each species based on stem and crown characteristics. There were consistent species and diameter class differences in the annual amount of foliage and fragments deposited. Foliage deposition rates ranged from just over 50 g m<sup>-2</sup> year<sup>-1</sup> in small diameter mountain hemlock stands to ???300 g m<sup>-2</sup> year<sup>-1</sup> for the three largest diameter classes of giant sequoia. The deposition rate for most woody fuel classes increased from the smallest diameter class stands to the largest diameter class stands. Woody fuel deposition rates varied among species as well. The rates for the smallest woody fuels ranged from 0.8 g m<sup>-2</sup> year<sup>-1</sup> for small diameter stands of Jeffrey pine to 126.9 g m<sup>-2</sup> year<sup>-1</sup> for very large diameter stands of mountain hemlock. Crown height and live crown ratio were the best predictors of fuel deposition rates for most fuel classes and species. Both characteristics reflect the amount of crown biomass including foliage and woody fuels. Relationships established in this study allow predictions of fuel loads to be made on a stand basis for each of these species under current and possible future conditions. These predictions can be used to estimate fuel treatment longevity, assist in determining fuel model transitions, and predict future changes in fuel bed characteristics.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Forest Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.foreco.2010.02.024","issn":"03781127","usgsCitation":"van Wagtendonk, J., and Moore, P., 2010, Fuel deposition rates of montane and subalpine conifers in the central Sierra Nevada, California, USA: Forest Ecology and Management, v. 259, no. 10, p. 2122-2132, https://doi.org/10.1016/j.foreco.2010.02.024.","startPage":"2122","endPage":"2132","numberOfPages":"11","costCenters":[],"links":[{"id":217328,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.foreco.2010.02.024"},{"id":245268,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"259","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1409e4b0c8380cd54895","contributors":{"authors":[{"text":"van Wagtendonk, J.

Explanatory variables that could be used for identifying potential bacteria loading mechanisms, such as bed shear stress due to a combined wave-current boundary layer and wave runup on the beach surface, were derived from an existing wave and current database. The derived hydrodynamic variables, along with the actual observed E. coli concentrations in the submerged and foreshore sands, were expected to reveal bacteria loading through nearshore sediment resuspension and swash on the beach surface, respectively. Based on the observation that onshore waves tend to result in a more active hydrodynamic system at this embayed beach, multiple linear regression analysis of onshore-wave cases further indicated the significance of sediment resuspension and the interaction of swash with gull-droppings in explaining the variability of E. coli concentration in the knee-deep water. For cases with longshore currents, numerical simulations using the Princeton Ocean Model revealed current circulation patterns inside the embayment, which can effectively entrain bacteria from the swash zone into the central area of the embayed beach water and eventually release them out of the embayment. The embayed circulation patterns are consistent with the statistical results that identified that 1) the submerged sediment was an additional net source of E. coli to the offshore water and 2) variability of E. coli concentration in the knee-deep water contributed adversely to that in the offshore water for longshore-current cases. The embayed beach setting and the statistical and numerical methods used in the present study have wide applicability for analyzing recreational water quality at similar marine and freshwater sites. ?? 2010 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es100797r","issn":"0013936X","usgsCitation":"Ge, Z., Nevers, M., Schwab, D., and Whitman, R., 2010, Coastal loading and transport of Escherichia coli at an embayed beach in Lake Michigan: Environmental Science & Technology, v. 44, no. 17, p. 6731-6737, https://doi.org/10.1021/es100797r.","startPage":"6731","endPage":"6737","numberOfPages":"7","costCenters":[],"links":[{"id":217354,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es100797r"},{"id":245298,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"17","noUsgsAuthors":false,"publicationDate":"2010-08-05","publicationStatus":"PW","scienceBaseUri":"5059f785e4b0c8380cd4cb74","contributors":{"authors":[{"text":"Ge, Z.","contributorId":99769,"corporation":false,"usgs":true,"family":"Ge","given":"Z.","email":"","affiliations":[],"preferred":false,"id":461090,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nevers, M.B.","contributorId":13787,"corporation":false,"usgs":true,"family":"Nevers","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":461087,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schwab, D.J.","contributorId":23730,"corporation":false,"usgs":true,"family":"Schwab","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":461088,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Whitman, R.L.","contributorId":69750,"corporation":false,"usgs":true,"family":"Whitman","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":461089,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

It is well known that Love-wave generation requires the existence of a low S-wave velocity layer in a multilayered earth model. In order to study numerically the propagation of Love waves in a layered earth model and dispersion characteristics for near-surface applications, we simulate high-frequency (>5 Hz) Love waves by the staggered-grid finite-difference (FD) method. The air-earth boundary (the shear stress above the free surface) is treated using the stress-imaging technique. We use a two-layer model to demonstrate the accuracy of the staggered-grid modeling scheme. We also simulate four-layer models including a low-velocity layer (LVL) or a high-velocity layer (HVL) to analyze dispersive energy characteristics for near-surface applications. Results demonstrate that: (1) the staggered-grid FD code and stress-imaging technique are suitable for treating the free-surface boundary conditions for Love-wave modeling, (2) Love-wave inversion should be treated with extra care when a LVL exists because of a lack of LVL information in dispersions aggravating uncertainties in the inversion procedure, and (3) energy of high modes in a low-frequency range is very weak, so that it is difficult to estimate the cutoff frequency accurately, and \"mode-crossing\" occurs between the second higher and third higher modes when a HVL exists. ?? 2010 Birkh??user / Springer Basel AG.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00024-010-0144-7","issn":"00334553","usgsCitation":"Luo, Y., Xia, J., Xu, Y., Zeng, C., and Liu, J., 2010, Finite-difference modeling and dispersion analysis of high-frequency love waves for near-surface applications: Pure and Applied Geophysics, v. 167, no. 12, p. 1525-1536, https://doi.org/10.1007/s00024-010-0144-7.","startPage":"1525","endPage":"1536","numberOfPages":"12","costCenters":[],"links":[{"id":246081,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218099,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00024-010-0144-7"}],"volume":"167","issue":"12","noUsgsAuthors":false,"publicationDate":"2010-04-23","publicationStatus":"PW","scienceBaseUri":"505a102ee4b0c8380cd53b75","contributors":{"authors":[{"text":"Luo, Y.","contributorId":28417,"corporation":false,"usgs":true,"family":"Luo","given":"Y.","email":"","affiliations":[],"preferred":false,"id":461735,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xia, J.","contributorId":63513,"corporation":false,"usgs":true,"family":"Xia","given":"J.","email":"","affiliations":[],"preferred":false,"id":461737,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Xu, Y.","contributorId":47816,"corporation":false,"usgs":true,"family":"Xu","given":"Y.","email":"","affiliations":[],"preferred":false,"id":461736,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zeng, C.","contributorId":94519,"corporation":false,"usgs":true,"family":"Zeng","given":"C.","email":"","affiliations":[],"preferred":false,"id":461738,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Liu, J.","contributorId":23672,"corporation":false,"usgs":false,"family":"Liu","given":"J.","affiliations":[],"preferred":false,"id":461734,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Enhanced growth sensitivity to climate is widely observed among trees that die, indicating that a predisposing physiological mechanism(s) underlies tree mortality. We tested three, linked hypotheses regarding mortality using a ponderosa pine (<i>Pinus ponderosa</i>) elevation transect that experienced low-elevation mortality following prolonged drought. The hypotheses were: (1) mortality was associated with greater growth sensitivity to climate, (2) mortality was associated with greater sensitivity of gas exchange to climate, and (3) growth and gas exchange were correlated. Support for all three hypotheses would indicate that mortality results at least in part from gas exchange constraints. We assessed growth using basal area increment normalized by tree basal area [basal area increment (BAI)/basal area (BA)] to account for differences in tree size. Whole-crown gas exchange was indexed via estimates of the CO<sub>2</sub> partial pressure difference between leaf and atmosphere (<i>p</i><sub>a</sub>−<i>p</i><sub>c</sub>) derived from tree ring carbon isotope ratios (<i>δ</i><sup>13</sup>C), corrected for temporal trends in atmospheric CO<sub>2</sub> and <i>δ</i><sup>13</sup>C and elevation trends in pressure. Trees that survived the drought exhibited strong correlations among and between BAI, BAI/BA, <i>p</i><sub>a</sub>−<i>p</i><sub>c</sub>, and climate. In contrast, trees that died exhibited greater growth sensitivity to climate than trees that survived, no sensitivity of <i>p</i><sub>a</sub>−<i>p</i><sub>c</sub> to climate, and a steep relationship between <i>p</i><sub>a</sub>−<i>p</i><sub>c</sub> and BAI/BA. The <i>p</i><sub>a</sub>−<i>p</i><sub>c</sub> results are consistent with predictions from a theoretical hydraulic model, suggesting trees that died had a limited buffer between mean water availability during their lifespan and water availability during drought – i.e., chronic water stress. It appears that chronic water stress predisposed low-elevation trees to mortality during drought via constrained gas exchange. Continued intensification of drought in mid-latitude regions may drive increased mortality and ecotone shifts in temperate forests and woodlands.</p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2486.2009.01994.x","usgsCitation":"McDowell, N., Allen, C.D., and Marshall, L., 2010, Growth, carbon-isotope discrimination, and drought-associated mortality across a Pinus ponderosa elevational transect: Global Change Biology, v. 16, no. 1, p. 399-415, https://doi.org/10.1111/j.1365-2486.2009.01994.x.","productDescription":"17 p.","startPage":"399","endPage":"415","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":244396,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"16","issue":"1","noUsgsAuthors":false,"publicationDate":"2009-12-02","publicationStatus":"PW","scienceBaseUri":"505a2e0fe4b0c8380cd5c288","contributors":{"authors":[{"text":"McDowell, N.G.","contributorId":93296,"corporation":false,"usgs":true,"family":"McDowell","given":"N.G.","email":"","affiliations":[],"preferred":false,"id":444618,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Allen, Craig D. 0000-0002-8777-5989 craig_allen@usgs.gov","orcid":"https://orcid.org/0000-0002-8777-5989","contributorId":2597,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"craig_allen@usgs.gov","middleInitial":"D.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":444617,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Marshall, L.","contributorId":37171,"corporation":false,"usgs":true,"family":"Marshall","given":"L.","email":"","affiliations":[],"preferred":false,"id":444616,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These shells are composed largely of aragonite (CaCO3) and potentially could be used for radiocarbon dating, but they must meet two criteria before their 14C ages can be considered to be reliable: (1) when gastropods are alive, the 14C activity of their shells must be in equilibrium with the 14C activity of the atmosphere, and (2) after burial, their shells must behave as closed systems with respect to carbon. To evaluate the first criterion, we conducted a comprehensive examination of the 14C content of the most common small terrestrial gastropods in North America, including 247 AMS measurements of modern shell material (3749 individual shells) from 46 different species. The modern gastropods that we analyzed were all collected from habitats on carbonate terrain and, therefore, the data presented here represent worst-case scenarios. In sum, ~78% of the shell aliquots that we analyzed did not contain dead carbon from limestone or other carbonate rocks even though it was readily available at all sites, 12% of the aliquots contained between 5 and 10% dead carbon, and a few (3% of the total) contained more than 10%. These results are significantly lower than the 20-30% dead carbon that has been reported previously for larger taxa living in carbonate terrain. For the second criterion, we report a case study from the American Midwest in which we analyzed fossil shells of small terrestrial gastropods (7 taxa; 18 AMS measurements; 173 individual shells) recovered from late-Pleistocene sediments. The fossil shells yielded 14C ages that were statistically indistinguishable from 14C ages of well-preserved plant macrofossils from the same stratum. Although just one site, these results suggest that small terrestrial gastropod shells may behave as closed systems with respect to carbon over geologic timescales. More work on this subject is needed, but if our case study site is representative of other sites, then fossil shells of some small terrestrial gastropods, including at least five common genera, Catinella, Columella, Discus, Gastrocopta, and Succinea, should yield reliable 14C ages, regardless of the local geologic substrate. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Geochronology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.quageo.2010.01.001","issn":"18711014","usgsCitation":"Pigati, J., Rech, J., and Nekola, J., 2010, Radiocarbon dating of small terrestrial gastropod shells in North America: Quaternary Geochronology, v. 5, no. 5, p. 519-532, https://doi.org/10.1016/j.quageo.2010.01.001.","startPage":"519","endPage":"532","numberOfPages":"14","costCenters":[],"links":[{"id":246289,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218290,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.quageo.2010.01.001"}],"volume":"5","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a93e1e4b0c8380cd810a7","contributors":{"authors":[{"text":"Pigati, J.S.","contributorId":80486,"corporation":false,"usgs":true,"family":"Pigati","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":456354,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rech, J.A.","contributorId":79659,"corporation":false,"usgs":true,"family":"Rech","given":"J.A.","affiliations":[],"preferred":false,"id":456353,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nekola, J.C.","contributorId":83776,"corporation":false,"usgs":true,"family":"Nekola","given":"J.C.","affiliations":[],"preferred":false,"id":456355,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This work was conducted as part of a 2007 assessment of Paleogene-Neogene strata of the northern Gulf of Mexico Basin, including the United States onshore and state waters (Dubiel et al., 2007). The assessed area is within the Upper Jurassic-CretaceousTertiary composite total petroleum system, which was defined for the assessment. Source rocks for Claiborne oil accumulations are interpreted to be organic-rich, downdip, shaley facies of the Wilcox Group and the Sparta Sand of the Claiborne Group; gas accumulations may have originated from multiple sources, including the Jurassic Smackover Formation and the Haynesville and Bossier shales, the Cretaceous Eagle Ford and Pearsall (?) formations, and the Paleogene Wilcox Group and Sparta Sand. Hydrocarbon generation in the basin started prior to deposition of Claiborne sediments and is currently ongoing. Primary reservoir sandstones in the Claiborne Group include, from oldest to youngest, the Queen City Sand, Cook Mountain Formation, Sparta Sand, Yegua Formation, and the laterally equivalent Cockfield Formation. A geologic model, supported by spatial analysis of petroleum geology data, including discovered reservoir depths, thicknesses, temperatures, porosities, permeabilities, and pressures, was used to divide the Claiborne Group into seven assessment units (AUs) with three distinctive structural and depositional settings. The three structural and depositional settings are (1) stable shelf, (2) expanded fault zone, and (3) slope and basin floor; the seven AUs are (1) lower Claiborne stable-shelf gas and oil, (2) lower Claiborne expanded fault-zone gas, (3) lower Claiborne slope and basin-floor gas, (4) lower Claiborne Cane River, (5) upper Claiborne stable-shelf gas and oil, (6) upper Claiborne expanded fault-zone gas, and (7) upper Claiborne slope and basin-floor gas. Based on Monte Carlo simulation of justified input parameters, the total estimated mean undiscovered conventional hydrocarbon resources in the seven AUs combined are 52 million bbl of oil, 19.145 tcf of natural gas, and 1.205 billion bbl of natural gas liquids. This article describes the conceptual geologic model used to define the seven Claiborne AUs, the characteristics of each AU, and the justification behind the input parameters used to estimate undiscovered resources for each AU. The great bulk of undiscovered hydrocarbon resources are predicted to be nonassociated gas and natural gas liquids contained in deep (mostiy >12,000-ft [3658 m], present-day drilling depths), overpressured, structurally complex outer shelf or slope and basin-floor Claiborne reservoirs. The continuing development of these downdip objectives is expected to be the primary focus of exploration activity for the onshore middle Eocene Gulf Coast in the coming decades. ?? 2010 U.S. Geological Survey.
