The solar energy reaching the Earth's surface and its oceans is thought to be controlled through an interaction between TSI and GCRs, which are theorized to ionize the atmosphere and increase cloud formation and its resultant albedo. High (low) GCR flux may promote cloudiness (clear skies) and higher (lower) albedo at the same time that TSI is lowest (highest) in the solar cycle which in turn creates cooler (warmer) ocean temperature anomalies. These anomalies have been shown to affect atmospheric flow patterns and ultimately affect precipitation over the Midwestern United States. This investigation identified a relation among TSI and geomagnetic index aa (GI-AA), and streamflow in the Mississippi River Basin for the period 1878-2004. The GI-AA was used as a proxy for GCRs. The lag time between the solar signal and streamflow in the Mississippi River at St. Louis, Missouri is approximately 34 years. The current drought (1999-2007) in the Mississippi River Basin appears to be caused by a period of lower solar activity that occurred between 1963 and 1977. There appears to be a solar \"fingerprint\" that can be detected in climatic time series in other regions of the world, with each series having a unique lag time between the solar signal and the hydroclimatic response. A progression of increasing lag times can be spatially linked to the ocean conveyor belt, which may transport the solar signal over a time span of several decades. The lag times for any one region vary slightly and may be linked to the fluctuations in the velocity of the ocean conveyor belt.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Advances in Space Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.asr.2007.02.079","issn":"02731177","usgsCitation":"Perry, C.A., 2007, Evidence for a physical linkage between galactic cosmic rays and regional climate time series: Advances in Space Research, v. 40, no. 3, p. 353-364, https://doi.org/10.1016/j.asr.2007.02.079.","startPage":"353","endPage":"364","numberOfPages":"12","costCenters":[],"links":[{"id":211619,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.asr.2007.02.079"},{"id":238938,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"40","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d30e4b0c8380cd52e79","contributors":{"authors":[{"text":"Perry, C.

However, species occurrence data are often lacking and typically limited to presence points at broad scales. This lack of absence data precludes the use of many statistical techniques for HCMs. One option is to generate pseudo-absence points so that the many available statistical modeling tools can be used. Traditional techniques generate pseudoabsence points at random across broadly defined species ranges, often failing to include biological knowledge concerning the species-habitat relationship. We incorporated biological knowledge of the species-habitat relationship into pseudo-absence points by creating habitat envelopes that constrain the region from which points were randomly selected. We define a habitat envelope as an ecological representation of a species, or species feature's (e.g., nest) observed distribution (i.e., realized niche) based on a single attribute, or the spatial intersection of multiple attributes. We created HCMs for Northern Goshawk (Accipiter gentilis atricapillus) nest habitat during the breeding season across Utah forests with extant nest presence points and ecologically based pseudo-absence points using logistic regression. Predictor variables were derived from 30-m USDA Landfire and 250-m Forest Inventory and Analysis (FIA) map products. These habitat-envelope-based models were then compared to null envelope models which use traditional practices for generating pseudo-absences. Models were assessed for fit and predictive capability using metrics such as kappa, thresholdindependent receiver operating characteristic (ROC) plots, adjusted deviance (Dadj2), and cross-validation, and were also assessed for ecological relevance. For all cases, habitat envelope-based models outperformed null envelope models and were more ecologically relevant, suggesting that incorporating biological knowledge into pseudo-absence point generation is a powerful tool for species habitat assessments. Furthermore, given some a priori knowledge of the species-habitat relationship, ecologically based pseudo-absence points can be applied to any species, ecosystem, data resolution, and spatial extent. ?? 2007 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/06-1312.1","issn":"10510761","usgsCitation":"Zarnetske, P., Edwards, T., and Moisen, G.G., 2007, Habitat classification modeling with incomplete data: Pushing the habitat envelope: Ecological Applications, v. 17, no. 6, p. 1714-1726, https://doi.org/10.1890/06-1312.1.","startPage":"1714","endPage":"1726","numberOfPages":"13","costCenters":[],"links":[{"id":211537,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/06-1312.1"},{"id":238839,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f03e4b0c8380cd5c9f7","contributors":{"authors":[{"text":"Zarnetske, P.L.","contributorId":27257,"corporation":false,"usgs":true,"family":"Zarnetske","given":"P.L.","email":"","affiliations":[],"preferred":false,"id":429622,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Edwards, T.C.

All 16 females that failed to successfully reproduce departed the YKD and moulted remiges either on the north coast of the Chukotka Peninsula, Russia (n=15), or on St. Lawrence Island, Alaska (n=1). Of 16 females that successfully nested, one migrated to Russia following hatch whereas the remainder stayed on the YKD. While moulting on the Chukotka Peninsula, emperor geese with satellite transmitters primarily used coastal lagoons west of Kolyuchin Bay. We observed 21,150 adult-plumaged emperor geese during aerial surveys in Chukotka in 2002. Most (95%) were in the same region used by geese that had been marked with satellite transmitters in Alaska. The number of emperor geese observed in Russia was comparable to our estimate of &ge;20,000 adults that either do not nest or nest unsuccessfully each year on the YKD, suggesting that most nonproductive adults, or &ge;28% of the adult population departs the YKD to moult elsewhere. The number of moult migrants may be substantially higher in years of poor reproductive success or if adult-plumaged birds that are not of breeding age also leave the YKD. Moult migration of emperor geese between Alaska and Russia is likely substantially greater than previously believed. Russian moulting habitats are important to the North American population of emperor geese and events that affect survival of geese in Russia could impact population trends on the YKD. Protection of coastal lagoons on the north coast of Chukotka is warranted.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.0908-8857.2007.03969.x","issn":"09088857","usgsCitation":"Hupp, J.W., Schmutz, J.A., Ely, C.R., Syroechkovskiy, E., Kondratyev, A.V., Eldridge, W., and Lappo, E., 2007, Moult migration of emperor geese Chen canagica between Alaska and Russia: Journal of Avian Biology, v. 38, no. 4, p. 462-470, https://doi.org/10.1111/j.0908-8857.2007.03969.x.","productDescription":"9 p.","startPage":"462","endPage":"470","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":438858,"rank":10000,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P9GJQ6LF","text":"USGS data release","linkHelpText":"Tracking Data for Emperor Geese (Anser canagicus)"},{"id":238995,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211663,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.2007.0908-8857.03969.x"}],"volume":"38","issue":"4","noUsgsAuthors":false,"publicationDate":"2007-11-06","publicationStatus":"PW","scienceBaseUri":"505a5e8de4b0c8380cd70b01","contributors":{"authors":[{"text":"Hupp, Jerry W. 0000-0002-6439-3910 jhupp@usgs.gov","orcid":"https://orcid.org/0000-0002-6439-3910","contributorId":127803,"corporation":false,"usgs":true,"family":"Hupp","given":"Jerry","email":"jhupp@usgs.gov","middleInitial":"W.","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":428928,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schmutz, Joel A. 0000-0002-6516-0836 jschmutz@usgs.gov","orcid":"https://orcid.org/0000-0002-6516-0836","contributorId":1805,"corporation":false,"usgs":true,"family":"Schmutz","given":"Joel","email":"jschmutz@usgs.gov","middleInitial":"A.","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":428927,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ely, Craig R. 0000-0003-4262-0892 cely@usgs.gov","orcid":"https://orcid.org/0000-0003-4262-0892","contributorId":3214,"corporation":false,"usgs":true,"family":"Ely","given":"Craig","email":"cely@usgs.gov","middleInitial":"R.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":428932,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Syroechkovskiy, E.E.

Examples of cross-scale pattern-process relationships and interactions among forest dieback, fire, and erosion are illustrated from northern New Mexico (USA) landscapes, where long-term studies have recently documented all of these disturbance processes. For example, environmental stress, operating on individual trees, can cause tree death that is amplified by insect mortality agents to propagate to patch and then landscape or even regional-scale forest dieback. Severe drought and unusual warmth in the southwestern USA since the late 1990s apparently exceeded species-specific physiological thresholds for multiple tree species, resulting in substantial vegetation mortality across millions of hectares of woodlands and forests in recent years. Predictions of forest dieback across spatial scales are constrained by uncertainties associated with: limited knowledge of species-specific physiological thresholds; individual and site-specific variation in these mortality thresholds; and positive feedback loops between rapidly-responding insect herbivore populations and their stressed plant hosts, sometimes resulting in nonlinear “pest” outbreak dynamics. Fire behavior also exhibits nonlinearities across spatial scales, illustrated by changes in historic fire regimes where patch-scale grazing disturbance led to regional-scale collapse of surface fire activity and subsequent recent increases in the scale of extreme fire events in New Mexico. Vegetation dieback interacts with fire activity by modifying fuel amounts and configurations at multiple spatial scales. Runoff and erosion processes are also subject to scale-dependent threshold behaviors, exemplified by ecohydrological work in semiarid New Mexico watersheds showing how declines in ground surface cover lead to non-linear increases in bare patch connectivity and thereby accelerated runoff and erosion at hillslope and watershed scales. Vegetation dieback, grazing, and fire can change land surface properties and cross-scale hydrologic connectivities, directly altering ecohydrological patterns of runoff and erosion. The interactions among disturbance processes across spatial scales can be key drivers in ecosystem dynamics, as illustrated by these studies of recent landscape changes in northern New Mexico. To better anticipate and mitigate accelerating human impacts to the planetary ecosystem at all spatial scales, improvements are needed in our conceptual and quantitative understanding of cross-scale interactions among disturbance processes.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10021-007-9057-4","usgsCitation":"Allen, C.D., 2007, Interactions across spatial scales among forest dieback, fire, and erosion in northern New Mexico landscapes: Ecosystems, v. 10, no. 5, p. 797-808, https://doi.org/10.1007/s10021-007-9057-4.","productDescription":"12 p.","startPage":"797","endPage":"808","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":488068,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.unl.edu/natrespapers/104","text":"External Repository"},{"id":238928,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New Mexico","volume":"10","issue":"5","noUsgsAuthors":false,"publicationDate":"2007-06-20","publicationStatus":"PW","scienceBaseUri":"505a3cbce4b0c8380cd62fbc","contributors":{"authors":[{"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":428918,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The two questions that need to be answered when considering an ESA listing are; (1) Is the entity a species under the ESA and if so (2) is the \"species\" in danger of extinction or likely to become an endangered species in the foreseeable future throughout all or a significant portion of its range? Green sturgeon genetic analyses showed strong differentiation between northern and southern populations, and therefore, the species was divided into Northern and Southern Distinct Population Segments (DPSs). The Northern DPS includes populations in the Rogue, Klamath-Trinity, and Eel rivers, while the Southern DPS only includes a single population in the Sacramento River. The principal risk factors for green sturgeon include loss of spawning habitat, harvest, and entrainment. The Northern DPS is not considered to be in danger of extinction or likely to become an endangered species in the foreseeable future. The loss of spawning habitat is not large enough to threaten this DPS, although the Eel River has been severely impacted by sedimentation due to poor land use practices and floods. The two main spawning populations in the Rogue and Klamath-Trinity rivers occupy separate basins reducing the potential for loss of the DPS through catastrophic events. Harvest has been substantially reduced and green sturgeon in this DPS do not face substantial entrainment loss. However there are significant concerns due to lack of information, flow and temperature issues, and habitat degradation. The Southern DPS is considered likely to become an endangered species in the foreseeable future. Green sturgeon in this DPS are concentrated into one spawning area outside of their natural habitat in the Sacramento River, making them vulnerable to catastrophic extinction. Green sturgeon spawning areas have been lost from the area above Shasta Dam on the Sacramento River and Oroville Dam on the Feather River. Entrainment of individuals into water diversion projects is an additional source of risk, and the large decline in numbers of green sturgeon entrained since 1986 causes additional concern. ?? 2006 Springer Science+Business Media B.V.</p>","language":"English","publisher":"Springer Netherlands","doi":"10.1007/s10641-006-9062-z","issn":"03781909","usgsCitation":"Adams, P., Grimes, C., Hightower, J., Lindley, S., Moser, M., and Parsley, M., 2007, Population status of North American green sturgeon, Acipenser medirostris: Environmental Biology of Fishes, v. 79, no. 3-4, p. 339-356, https://doi.org/10.1007/s10641-006-9062-z.","productDescription":"18 p.","startPage":"339","endPage":"356","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":211610,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10641-006-9062-z"},{"id":238927,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"79","issue":"3-4","noUsgsAuthors":false,"publicationDate":"2006-07-08","publicationStatus":"PW","scienceBaseUri":"505a7d95e4b0c8380cd7a031","contributors":{"authors":[{"text":"Adams, P.B.","contributorId":22576,"corporation":false,"usgs":true,"family":"Adams","given":"P.B.","email":"","affiliations":[],"preferred":false,"id":428913,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grimes, C.","contributorId":55205,"corporation":false,"usgs":true,"family":"Grimes","given":"C.","email":"","affiliations":[],"preferred":false,"id":428914,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hightower, J.E.","contributorId":16605,"corporation":false,"usgs":true,"family":"Hightower","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":428912,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lindley, S.T.","contributorId":58458,"corporation":false,"usgs":true,"family":"Lindley","given":"S.T.","email":"","affiliations":[],"preferred":false,"id":428915,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Moser, M.L.","contributorId":92006,"corporation":false,"usgs":true,"family":"Moser","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":428917,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Parsley, M.J.","contributorId":59542,"corporation":false,"usgs":true,"family":"Parsley","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":428916,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

CO2 storage capacity assessments may be conducted at various scales-in decreasing order of size and increasing order of resolution: country, basin, regional, local and site-specific. Estimation of the CO2 storage capacity in depleted oil and gas reservoirs is straightforward and is based on recoverable reserves, reservoir properties and in situ CO2 characteristics. In the case of CO2-EOR, the CO2 storage capacity can be roughly evaluated on the basis of worldwide field experience or more accurately through numerical simulations. Determination of the theoretical CO2 storage capacity in coal beds is based on coal thickness and CO2 adsorption isotherms, and recovery and completion factors. Evaluation of the CO2 storage capacity in deep saline aquifers is very complex because four trapping mechanisms that act at different rates are involved and, at times, all mechanisms may be operating simultaneously. The level of detail and resolution required in the data make reliable and accurate estimation of CO2 storage capacity in deep saline aquifers practical only at the local and site-specific scales. This paper follows a previous one on issues and development of standards for CO2 storage capacity estimation, and provides a clear set of definitions and methodologies for the assessment of CO2 storage capacity in geological media. Notwithstanding the defined methodologies suggested for estimating CO2 storage capacity, major challenges lie ahead because of lack of data, particularly for coal beds and deep saline aquifers, lack of knowledge about the coefficients that reduce storage capacity from theoretical to effective and to practical, and lack of knowledge about the interplay between various trapping mechanisms at work in deep saline aquifers. ?? 2007 Elsevier Ltd.

We combine new trace-element data on lower crustal xenoliths from the Mesozoic Sierra Nevada Batholith with an extensive grid-based geochemical map of the Peninsular Ranges Batholith, the southern equivalent of the Sierras. Collectively, these observations give a three-dimensional view of the crust, which permits the petrogenesis and tectonics of Phanerozoic crust formation to be linked in space and time. Subduction of the Farallon plate beneath North America during the Triassic to early Cretaceous was characterized by trench retreat and slab rollback because old and cold oceanic lithosphere was being subducted. This generated an extensional subduction zone, which created fringing island arcs just off the Paleozoic continental margin. However, as the age of the Farallon plate at the time of subduction decreased, the extensional environment waned, allowing the fringing island arc to accrete onto the continental margin. With continued subduction, a continental arc was born and a progressively more compressional environment developed as the age of subducting slab continued to young. Refinement into a felsic crust occurred after accretion, that is, during the continental arc stage, wherein a thickened crustal and lithospheric column permitted a longer differentiation column. New basaltic arc magmas underplate and intrude the accreted terrane, suture, and former continental margin. Interaction of these basaltic magmas with pre-existing crust and lithospheric mantle created garnet pyroxenitic mafic cumulates by fractional crystallization at depth as well as gabbroic and garnet pyroxenitic restites at shallower levels by melting of pre-existing lower crust. The complementary felsic plutons formed by these deep-seated differentiation processes rose into the upper crust, stitching together the accreted terrane, suture and former continental margin. The mafic cumulates and restites, owing to their high densities, eventually foundered into the mantle, leaving behind a more felsic crust. Our grid-based sampling allows us to estimate an unbiased average upper crustal composition for the Peninsular Ranges Batholith. Major and trace-element compositions are very similar to global continental crust averaged over space and time, but in detail, the Peninsular Ranges are slightly lower in compatible to mildly incompatible elements, MgO, Mg#, V, Sc, Co, and Cr. The compositional similarities suggest a strong arc component in global continental crust, but the slight discrepancies suggest that additional crust formation processes are also important in continent formation as a whole. Finally, the delaminated Sierran garnet pyroxenites have some of the lowest U/Pb ratios ever measured for silicate rocks. Such material, if recycled and stored in the deep mantle, would generate a reservoir with very unradiogenic Pb, providing one solution to the global Pb isotope paradox.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.epsl.2007.09.025","issn":"0012821X","usgsCitation":"Lee, C., Morton, D.M., Kistler, R.W., and Baird, A.K., 2007, Petrology and tectonics of Phanerozoic continent formation: From island arcs to accretion and continental arc magmatism: Earth and Planetary Science Letters, v. 263, no. 3-4, p. 370-387, https://doi.org/10.1016/j.epsl.2007.09.025.","productDescription":"18 p.","startPage":"370","endPage":"387","numberOfPages":"18","costCenters":[],"links":[{"id":240007,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"263","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a782be4b0c8380cd7865b","contributors":{"authors":[{"text":"Lee, C.-T.A.","contributorId":20549,"corporation":false,"usgs":true,"family":"Lee","given":"C.-T.A.","email":"","affiliations":[],"preferred":false,"id":432729,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morton, D.

Fish (n = 62, 226-464 mm total length) from six sites in southern Missouri were captured by electrofishing. Blood samples (1 mL) from each fish were obtained by caudal veinipuncture with a heparinized needle and syringe. Biopsy needle (10 mm x 14 gauge; three cuts per fish; 10-20 mg total dry weight) and biopsy punch (7 mm x 5 mm in diameter, one plug per fish, 30-50 mg dry weight) samples were obtained from the area beneath the dorsal fin. Fillet samples were obtained from the opposite side of the fish. All samples were freeze-dried and analyzed for total Hg by combustion amalgamation atomic absorption spectrophotometry. Mean relative standard deviations (RSDs) of triplicate samples were similar for all four methods (2.2-2.4%), but the range of RSDs was greater for blood (0.4-5.5%) than for the muscle methods (1.8-4.0%). Total Hg concentrations in muscle were 0.0200-0.8809 ??g/g wet weight; concentrations in plug, needle, and fillet samples from each fish were nearly identical. Blood Hg concentrations were 0.0006-0.0812 ??g/mL and were highly correlated with muscle concentrations; linear regressions between log-transformed blood and fillet Hg concentrations were linear and statistically significant (p &lt; 0.01), and explained 91-93% of the total variation. Correlations between fillet Hg concentrations and fish size and age were weak; together they explained ???37% of the total variation, and the relations differed among sites. Overall, any of the alternative methods could provide satisfactory estimates of fillet Hg in smallmouth bass; however, both blood and plug sampling with disposable instruments were easier to perform than needle sampling. The biopsy needle was the most difficult to use, especially on smaller fish, and its relative expense necessitates reuse and, consequently, thorough cleaning between fish to prevent cross-contamination. ?? 2007 Springer Science+Business Media, LLC.</p>","language":"English","publisher":"Springer-Verlag","doi":"10.1007/s00244-006-0214-0","issn":"00904341","usgsCitation":"Schmitt, C., and Brumbaugh, W.G., 2007, Evaluation of potentially nonlethal sampling methods for monitoring mercury concentrations in smallmouth bass (Micropterus dolomieu): Archives of Environmental Contamination and Toxicology, v. 53, no. 1, p. 84-95, https://doi.org/10.1007/s00244-006-0214-0.","productDescription":"12 p.","startPage":"84","endPage":"95","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":240301,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212765,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00244-006-0214-0"}],"country":"United States","state":"Missouri","otherGeospatial":"Southeast Missouri","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -90.274658203125,\n              38.09133660751176\n            ],\n            [\n              -91.417236328125,\n              38.134556577054134\n            ],\n            [\n              -91.38427734374999,\n              36.56260003738548\n            ],\n            [\n              -90.164794921875,\n              36.474306755095206\n            ],\n            [\n              -89.5166015625,\n              36.48314061639213\n            ],\n            [\n              -89.154052734375,\n              36.77409249464195\n            ],\n            [\n              -89.219970703125,\n              37.046408899699564\n            ],\n            [\n              -89.4287109375,\n              37.06394430056685\n            ],\n            [\n              -89.49462890625,\n              37.309014074275915\n            ],\n            [\n              -89.549560546875,\n              37.67512527892127\n            ],\n            [\n              -90.186767578125,\n              38.07404145941957\n            ],\n            [\n              -90.274658203125,\n              38.09133660751176\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"53","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-05-04","publicationStatus":"PW","scienceBaseUri":"505a0caee4b0c8380cd52c59","contributors":{"authors":[{"text":"Schmitt, C.

The Cedar Mountain Formation lies stratigraphically between the Tithonian-Berriasian (Upper Jurassic) Brushy Basin Member of the Morrison Formation and the Cenomanian (Upper Cretaceous) Dakota Formation. Detailed stratigraphic, sedimentological, geochronological, palynological, and paleontological data have been collected along a measured section at the site of the Cifelli #2 Eolambia caroljonesa Quarry. These data provide a chronostratigraphic and a biostratigraphic framework for the Cedar Mountain Formation and allow a detailed reconstruction of the paleoenvironment and the paleoecology of the local paleogeographic area from which E. caroljonesa have been recovered. Three 40Ar/39Ar ages ranging from 96.7 to 98.5 Ma have been obtained three stratigraphically distinct altered volcanic ash layers within the Mussentuchit Member, one of which passes through the E. caroljonesa quarry, that indicate that the quarry is latest Albian in age and that the stratigraphic boundary between the Mussentuchit Member of the Cedar Mountain Formation and the overlying Dakota Formation is at or near the Albian/Cenomanian boundary. Sedimentological and biostratigraphic data suggest that significant long-term and short-term climatic changes are recorded in the Cedar Mountain Formation. During deposition of the lower part of the formation, climatic conditions were warm and arid to semi-arid. During deposition of the upper part of the formation, conditions became more humid. The progressive change in climatic conditions was probably related to the transgression of the Mowry Sea from the north. Cyclic sedimentation in the Mussentuchit Member suggests high-frequency changes from wet to dry periods. ?? 2007 Elsevier Ltd.

Collectively, 67 females built 112 nests (1.67 ± 0.07 nests female</span><sup>−1</sup><span> season</span><sup>−1</sup><span>; range: 1–3); 34 were second nests and 11 were third nests. Daily nest survival estimates were similar for initial and later nests with overall nest survival (DSR</span><sup>19</sup><span>) of 30.7% and 31.7%, respectively. Nest predation was the most common cause of failure (92%). Capture and radiomarking of females did not affect nest survival. Lark Bunting dispersal probabilities increased among females that fledged young from initial nests and females that lost their original nests late in the season. Conservative and liberal estimates of mean annual fecundity were 0.96 ±0.11 and 1.24 ± 0.09 female offspring per female, respectively. Given the fecundity and juvenile-survival estimates for this population, annual adult survival values of 71–77% are necessary to achieve a stable population. Because adult survival of prairie passerines ranges between 55% and 65%, this study area may not be capable of sustaining a stable population in the absence of immigration. We contrast our population assessment with one that assumes indirect values of fecundity and juvenile survival. To elucidate limiting factors, estimation of population-specific demographic parameters is desirable. We present an approach for selecting species and areas for evaluation of population stability.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1642/0004-8038(2007)124[578:PDEPII]2.0.CO;2","issn":"00048038","usgsCitation":"Yackel Adams, A., Skagen, S., and Savidge, J.A., 2007, Population-specific demographic estimates provide insights into declines of Lark Buntings (<i>Calamospiza melanocorys</i>): The Auk, v. 124, no. 2, p. 578-593, https://doi.org/10.1642/0004-8038(2007)124[578:PDEPII]2.0.CO;2.","productDescription":"16 p.","startPage":"578","endPage":"593","costCenters":[],"links":[{"id":477211,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/0004-8038(2007)124[578:pdepii]2.0.co;2","text":"Publisher Index Page"},{"id":240297,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"124","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7dc2e4b0c8380cd7a137","contributors":{"authors":[{"text":"Yackel Adams, A.

Historical collections give an indication of which species occurred in an area at one time, although the ambiguity surrounding locations and environmental conditions associated with collection decreases the value of this information source. Resampling using the same general protocols can give valuable insights to changes in community structure. However, this is only feasible when sampling methodology and exact site locations are known. From 2002-2005 we resampled 12 sites in St. Marks National Wildlife Refuge in Florida's panhandle, an area in which intensive herpetological surveys were conducted in 1977-1979. We documented a general decrease in species richness among the diversely managed sites, changes in dominant species and diversity and an increasing trend toward homogeneity of the herpetofaunal community among habitats. Changes were attributed to four causes: 28-y of forest community succession, changes in management practices, non-detection of species due to variation in sampling conditions and a decrease in occupancy by four amphibians and three reptiles. The use of population and habitat-related indexes helped define possible influences on community change and can be used to target species for monitoring. Declines of these seven species are of concern, especially considering the protected status of the refuge and its increasing isolation as surrounding landscapes are converted to urbanized settings.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Midland Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1674/0003-0031(2007)158[29:CIANFG]2.0.CO;2","issn":"00030031","usgsCitation":"Dodd, C., Barichivich, W., Johnson, S., and Staiger, J., 2007, Changes in a northwestern Florida gulf coast herpetofaunal community over a 28-y period: American Midland Naturalist, v. 158, no. 1, p. 29-48, https://doi.org/10.1674/0003-0031(2007)158[29:CIANFG]2.0.CO;2.","startPage":"29","endPage":"48","numberOfPages":"20","costCenters":[],"links":[{"id":212877,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1674/0003-0031(2007)158[29:CIANFG]2.0.CO;2"},{"id":240436,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"158","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f408e4b0c8380cd4bacd","contributors":{"authors":[{"text":"Dodd, C.K.

Species of \"Zaphrentis\" have been named from every Paleozoic System except the Cambrian. Variants of the word, such as zaphrentoid, are widely used with varied meanings. Nomenclatural spinoffs are numerous: Neozaphrentis and Heterophrentis are obvious examples, but dozens of additional genera have type species that were originally described in Zaphrentis. Many paleontologists are familiar with the word but few really know what it means. Zaphrentis (as a subgenus) and five new species were named in 1820, based on corals from the Falls of the Ohio River between Louisville, Kentucky, and Clarksville, Indiana. Descriptions were minimal, none was illustrated, and no specimens were preserved as types. Nominal species of \"Zaphrentis\" proliferated for over 100 years before a redescription based on Falls specimens was published (1938), the probable source beds recognized (1942), a neotype selected (1965) and adequately described and illustrated (1981). At this time, I recognize only four zaphrentid genera: Zaphrentis (middle Eifelian), Heliophyllum (middle Emsian through Givetian), Aemulophyllum (middle Emsian), and Cyathocylindrium (lower Emsian?; middle Emsian through Eifelian). All four genera seem to have originated in the Eastern Americas Biogeographic Realm. Heliophyllum is the most common, has the longest stratigraphic range, and is the only one known to occur outside of its area of origin. Heliophyllum modicum n. sp., once discussed as a possible Zaphrentis, is described and compared with both the type species of Zaphrentis and other Heliophyllum species. A single coral specimen from the Indian Cove Formation (upper Pragian or lower Emsian), Gaspe??, Quebec, is considered the earliest known zaphrentid and is described as Cyathocylindrium? n. sp.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletins of American Paleontology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00075779","usgsCitation":"Oliver, W.A., 2007, Zaphrentis and the Zaphrentidae (Devonian; anthozoa, rugosa): Bulletins of American Paleontology, v. 2007, no. 372-373, p. 5-24.","startPage":"5","endPage":"24","numberOfPages":"20","costCenters":[],"links":[{"id":240402,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2007","issue":"372-373","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bd258e4b08c986b32f76e","contributors":{"authors":[{"text":"Oliver, W.

The Newark East gas field, located in the Fort Worth Basin, Texas, is defined by thermogenic gas production from low-porosity and low-permeability Barnett Shale. The Barnett Shale gas system, a self-contained source-reservoir system, has generated large amounts of gas in the key productive areas because of various characteristics and processes, including (1) excellent original organic richness and generation potential; (2) primary and secondary cracking of kerogen and retained oil, respectively; (3) retention of oil for cracking to gas by adsorption; (4) porosity resulting from organic matter decomposition; and (5) brittle mineralogical composition. The calculated total gas in place (GIP) based on estimated ultimate recovery that is based on production profiles and operator estimates is about 204 bcf/section (5.78 ?? 109 m3/1.73 ?? 104 m3). We estimate that the Barnett Shale has a total generation potential of about 609 bbl of oil equivalent/ac-ft or the equivalent of 3657 mcf/ac-ft (84.0 m3/m3). Assuming a thickness of 350 ft (107 m) and only sufficient hydrogen for partial cracking of retained oil to gas, a total generation potential of 820 bcf/section is estimated. Of this potential, approximately 60% was expelled, and the balance was retained for secondary cracking of oil to gas, if sufficient thermal maturity was reached. Gas storage capacity of the Barnett Shale at typical reservoir pressure, volume, and temperature conditions and 6% porosity shows a maximum storage capacity of 540 mcf/ac-ft or 159 scf/ton.

A simple spatial model was used to simulate horseshoe crab spawning that would occur on a typical Delaware Bay beach during spring tide cycles to quantify density-dependent nest disturbance. At least 20% of nests and eggs were disturbed for levels of spawning greater than one third of the average density in Delaware Bay during 2004. Nest disturbance increased approximately linearly as spawning density increased from one half to twice the 2004 level. As spawning density increased further, the percentage of eggs that were disturbed reached an asymptote of 70% for densities up to 10 times the density in 2004. Nest disturbance was heaviest in the mid beach zone. Nest disturbance precedes entrainment and begins the process of exhumation of eggs to surface sediments. Model predictions were combined with observations from egg surveys to estimate a snap-shot exhumation rate of 5-9% of disturbed eggs. Because an unknown quantity of eggs were exhumed and removed from the beach prior to the survey, cumulative exhumation rate was likely to have been higher than the snap-shot estimate. Because egg exhumation is density-dependent, in addition to managing for a high population size, identification and conservation of beaches where spawning horseshoe crabs concentrate in high densities (i.e., hot spots) are important steps toward providing a reliable food supply for migratory shorebirds.&nbsp;</p>","language":"English","publisher":"SpringerLink","doi":"10.1007/BF02700171","usgsCitation":"Smith, D., 2007, Effect of horseshoe crab spawning density on nest disturbance and exhumation of eggs: A simulation study: Estuaries and Coasts, v. 30, no. 2, p. 287-295, https://doi.org/10.1007/BF02700171.","productDescription":"9 p.","startPage":"287","endPage":"295","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":240496,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Delaware","otherGeospatial":"Delaware Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -75.35522460937499,\n              38.976492485539396\n            ],\n            [\n              -75.2398681640625,\n              38.852542390364235\n            ],\n            [\n              -74.970703125,\n              38.843986129756615\n            ],\n            [\n              -75.0421142578125,\n              39.0831721934762\n            ],\n            [\n              -75.1849365234375,\n              39.18117526158749\n            ],\n            [\n              -75.4156494140625,\n              39.142842478062505\n            ],\n            [\n              -75.35522460937499,\n              38.976492485539396\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"30","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a05e9e4b0c8380cd5100b","contributors":{"authors":[{"text":"Smith, D.

Simulated growth effects from reduced foraging efficiency were most prominent when hooking injuries occurred early in the fishing season. These simulations suggest that rainbow trout are most vulnerable to decreases in growth when salmon are abundant and spawning and, coincidentally, during the months when most fishing occurs.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2400.2007.00533.x","issn":"0969997X","usgsCitation":"Meka, J.M., and Margraf, F., 2007, Using a bioenergetic model to assess growth reduction from catch-and-release fishing and hooking injury in rainbow trout, <i>Oncorhynchus mykiss</i>: Fisheries Management and Ecology, v. 14, no. 2, p. 131-139, https://doi.org/10.1111/j.1365-2400.2007.00533.x.","productDescription":"9 p.","startPage":"131","endPage":"139","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":240463,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212898,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2400.2007.00533.x"}],"volume":"14","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-03-19","publicationStatus":"PW","scienceBaseUri":"505bc023e4b08c986b329f54","contributors":{"authors":[{"text":"Meka, Julie M.","contributorId":44713,"corporation":false,"usgs":false,"family":"Meka","given":"Julie","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":425166,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Margraf, F.J.","contributorId":47738,"corporation":false,"usgs":true,"family":"Margraf","given":"F.J.","email":"","affiliations":[],"preferred":false,"id":425167,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The wavelength ranges were chosen to maximize the science data that could be collected using existing semiconductor technologies and avoiding the need for multi-octave spectrometers. It was flown on DS1 to validate technologies derived from the development of PICS (Planetary Imaging Camera Spectrometer). These technologies provided a novel systems approach enabling the miniaturization and integration of four instruments into one entity, spanning a wavelength range from the UV to IR, and from ambient to cryogenic temperatures with optical performance at a fraction of a wavelength. The specific technologies incorporated were: a built-in fly-by sequence; lightweight and ultra-stable, monolithic silicon-carbide construction, which enabled room-temperature alignment for cryogenic (85-140 K) performance, and provided superb optical performance and immunity to thermal distortion; diffraction-limited, shared optics operating from 80 to 2600 nm; advanced detector technologies for the UV, visible and short-wavelength IR; high-performance thermal radiators coupled directly to the short-wave infrared (SWIR) detector optical bench, providing an instrument with a mass less than 10 kg, instrument power less than 10 W, and total instrument cost of less than ten million dollars. The design allows the wavelength range to be extended by at least an octave at the short wavelength end and to 50 microns at the long wavelength end. Testing of the completed instrument demonstrated excellent optical performance down to 77 K, which would enable a greatly reduced background for longer wavelength detectors. During the Deep Space 1 Mission, MICAS successfully collected images and spectra for asteroid 9969 Braille, Mars, and comet 19/P Borrelly. The Borrelly encounter was a scientific hallmark providing the first clear, high resolution images and excellent, short-wavelength infrared spectra of the surface of an active comet's nucleus. ?? 2007 Springer Science+Business Media, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Space Science Reviews","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11214-007-9155-9","issn":"00386308","usgsCitation":"Rodgers, D., Beauchamp, P., Soderblom, L., Brown, R.H., Chen, G., Lee, M., Sandel, B., Thomas, D., Benoit, R., and Yelle, R., 2007, Advanced technologies demonstrated by the miniature integrated camera and spectrometer (MICAS) aboard deep space 1: Space Science Reviews, v. 129, no. 4, p. 309-326, https://doi.org/10.1007/s11214-007-9155-9.","startPage":"309","endPage":"326","numberOfPages":"18","costCenters":[],"links":[{"id":212870,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11214-007-9155-9"},{"id":240429,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"129","issue":"4","noUsgsAuthors":false,"publicationDate":"2007-05-04","publicationStatus":"PW","scienceBaseUri":"5059e702e4b0c8380cd477c2","contributors":{"authors":[{"text":"Rodgers, D.H.","contributorId":83742,"corporation":false,"usgs":true,"family":"Rodgers","given":"D.H.","email":"","affiliations":[],"preferred":false,"id":425156,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beauchamp, P.M.","contributorId":49606,"corporation":false,"usgs":true,"family":"Beauchamp","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":425154,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Soderblom, L.A. 0000-0002-0917-853X","orcid":"https://orcid.org/0000-0002-0917-853X","contributorId":6139,"corporation":false,"usgs":true,"family":"Soderblom","given":"L.A.","affiliations":[],"preferred":false,"id":425148,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brown, R.

To test the effect of pyrite composition and environmental parameters on the rate and extent of pyrite oxidation in coal, splits of five bituminous coal samples having differing amounts of pyrite and extents of As substitution in the pyrite, were exposed to a range of simulated weathering conditions over a period of 17 months. Samples investigated include a Springfield coal from Indiana (whole coal pyritic S&nbsp;=&nbsp;2.13&nbsp;wt.%; As in pyrite&nbsp;=&nbsp;detection limit (d.l.) to 0.06&nbsp;wt.%), two Pittsburgh coal samples from West Virginia (pyritic S&nbsp;=&nbsp;1.32&ndash;1.58&nbsp;wt.%; As in pyrite&nbsp;=&nbsp;d.l. to 0.34&nbsp;wt.%), and two samples from the Warrior Basin, Alabama (pyritic S&nbsp;=&nbsp;0.26&ndash;0.27&nbsp;wt.%; As in pyrite&nbsp;=&nbsp;d.l. to 2.72&nbsp;wt.%).

For that purpose, probabilistic seismic demand analysis (PSDA) is used as a tool to estimate the mean annual frequency of exceeding a specified value of a structural demand parameter (e.g. interstorey drift). This paper compares and contrasts the use, in PSDA, of certain advanced scalar versus vector and conventional scalar ground motion intensity measures (IMs). One of the benefits of using a well-chosen IM is that more accurate evaluations of seismic performance are achieved without the need to perform detailed ground motion record selection for the nonlinear dynamic structural analyses involved in PSDA (e.g. record selection with respect to seismic parameters such as earthquake magnitude, source-to-site distance, and ground motion epsilon). For structural demands that are dominated by a first mode of vibration, using inelastic spectral displacement (Sdi) can be advantageous relative to the conventionally used elastic spectral acceleration (Sa) and the vector IM consisting of Sa and epsilon (??). This paper demonstrates that this is true for ordinary and for near-source pulse-like earthquake records. The latter ground motions cannot be adequately characterized by either Sa alone or the vector of Sa and ??. For structural demands with significant higher-mode contributions (under either of the two types of ground motions), even Sdi (alone) is not sufficient, so an advanced scalar IM that additionally incorporates higher modes is used.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earthquake Engineering and Structural Dynamics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/eqe.696","issn":"00988847","usgsCitation":"Tothong, P., and Luco, N., 2007, Probabilistic seismic demand analysis using advanced ground motion intensity measures: Earthquake Engineering and Structural Dynamics, v. 36, no. 13, p. 1837-1860, https://doi.org/10.1002/eqe.696.","startPage":"1837","endPage":"1860","numberOfPages":"24","costCenters":[],"links":[{"id":213038,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/eqe.696"},{"id":240618,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"13","noUsgsAuthors":false,"publicationDate":"2007-06-11","publicationStatus":"PW","scienceBaseUri":"505a8c98e4b0c8380cd7e796","contributors":{"authors":[{"text":"Tothong, P.","contributorId":107503,"corporation":false,"usgs":true,"family":"Tothong","given":"P.","email":"","affiliations":[],"preferred":false,"id":424748,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Luco, N.","contributorId":34240,"corporation":false,"usgs":true,"family":"Luco","given":"N.","email":"","affiliations":[],"preferred":false,"id":424747,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The mammoth was buried by loess, perhaps as a result of persistent dust storms, approximately 17 500 14C years ago.

Over one hundred bones or bone pieces have been excavated to-date. The skull, containing the tusks and maxillary teeth, is complete and in close proximity to associated postcranial remains, indicating that the mammoth died where it was found. The size and characteristics of skeletal elements have allowed us to determine that this was a mature male of about 41 years of age.

Contorted bedding and flow rolls preserved in tidal sediments within the estuary have previously been interpreted as resulting from the Mw 9.2 Great Alaskan earthquake of 1964. Horizons of flow rolls between undeformed beds in sediments and rock strata have been used to infer ancient earthquakes in other areas. Although many types of soft-sediment deformation structures can be formed by earthquakes, observations of sedimentation on tidal flats in the inner parts of Turnagain Arm in the summers of 2003 and 2004 show that a wide range of soft-sediment deformation structures, similar to those inferred to have been formed by earthquakes, can form in macrotidal estuaries in the absence of seismic shock. During sedimentation rate measurements in 2004, soft-sediment deformation structures were recorded that formed during one day's tide, either in response to overpressurization of tidal flats during rapid tidal drawdown or by shear stress exerted on the bed by the passage of a 1.8 m tidal bore. Structures consisted of How rolls, dish structures, flames, and small dewatering pipes in a bed 17 cm thick. In the future, if the flow rolls in Turnagain Arm were found in isolated outcrops across an area 11 km in length, in an estuary known to have been influenced by large-magnitude earthquakes, would they be interpreted as seismites? These examples show that caution is needed when using horizons of flow rolls to infer paleoseismicity in estuarine deposits because many of the mechanisms (tidal flux, tidal bores, slumping, flooding) that can cause deformation in rapidly deposited, unconsolidated silts and sands, are orders of magnitude more common than great earthquakes. ?? 2007 The Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G23209A.1","issn":"00917613","usgsCitation":"Greb, S., and Archer, A., 2007, Soft-sediment deformation produced by tides in a meizoseismic area, Turnagain Arm, Alaska: Geology, v. 35, no. 5, p. 435-438, https://doi.org/10.1130/G23209A.1.","startPage":"435","endPage":"438","numberOfPages":"4","costCenters":[],"links":[{"id":212686,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G23209A.1"},{"id":240211,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b91d7e4b08c986b319b36","contributors":{"authors":[{"text":"Greb, S.F.","contributorId":48294,"corporation":false,"usgs":true,"family":"Greb","given":"S.F.","email":"","affiliations":[],"preferred":false,"id":424646,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Archer, A.W.","contributorId":8620,"corporation":false,"usgs":true,"family":"Archer","given":"A.W.","affiliations":[],"preferred":false,"id":424645,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

To design more effective restoration strategies and re-establish native plant communities in disturbed wetlands, it is imperative to understand undisturbed systems. A site within Cherokee Marsh located in Madison, Wisconsin, USA, contains a relatively undisturbed area of wetland consisting of plant communities common within the prairie landscape including a fen, sedge meadow, and shallow marsh. These distinct communities are found within an area of minimal topographic relief, yet transitions from one community to the next occur over short distances. This study sought to characterize the geologic, hydrologic, and chemical gradients associated with these shifts in vegetation to gain insight into the factors controlling the spatial differences in dominant plant species, which could be critical for restoration success. Vegetation analyses revealed a transition of dominant sedge species, which appeared to correspond to changes in hydrology from a ground-water dominated to a surface-water dominated system (as determined by water isotopes). Along the same vegetation transect, subsurface coring results show a heterogeneous composition of peat and till with lateral and vertical variations in stratigraphy, which relates to variability in ground-water discharge as evidenced by hydroperiods and stable isotope composition. Applications of this type of approach throughout the glaciated terrains of the midwestern and northeastern United States and Canada can improve future wetland restoration and management.</span></p>","doi":"10.1672/0277-5212(2007)27[189:TIOSGF]2.0.CO;2","usgsCitation":"Kurtz, A., Bahr, J., Carpenter, Q.J., and Hunt, R., 2007, The importance of subsurface geology for water source and vegetation communities in Cherokee Marsh, Wisconsin: Wetlands, v. 27, no. 1, p. 189-202, https://doi.org/10.1672/0277-5212(2007)27[189:TIOSGF]2.0.CO;2.","productDescription":"14 p.","startPage":"189","endPage":"202","numberOfPages":"14","costCenters":[],"links":[{"id":241989,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wisconsin","otherGeospatial":"Cherokee Marsh","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.4015884399414,\n              43.137069765760344\n            ],\n            [\n              -89.3579864501953,\n              43.1529763194357\n            ],\n            [\n              -89.33446884155273,\n              43.162994070968374\n            ],\n            [\n              -89.33378219604492,\n              43.18427633964703\n            ],\n            [\n              -89.34288024902344,\n              43.19203626250746\n            ],\n            [\n              -89.38013076782227,\n              43.18527767545014\n            ],\n            [\n              -89.4063949584961,\n              43.158861947471785\n            ],\n            [\n              -89.41188812255858,\n              43.14258116631987\n            ],\n            [\n              -89.4093132019043,\n              43.1355665702956\n            ],\n            [\n              -89.4015884399414,\n              43.13656870471118\n            ],\n            [\n              -89.4015884399414,\n              43.137069765760344\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"27","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bacffe4b08c986b3238e4","contributors":{"authors":[{"text":"Kurtz, A.M.","contributorId":74969,"corporation":false,"usgs":true,"family":"Kurtz","given":"A.M.","email":"","affiliations":[],"preferred":false,"id":441779,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bahr, J.M.","contributorId":62346,"corporation":false,"usgs":true,"family":"Bahr","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":441778,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carpenter, Q.

To test this, we established twenty-four 100 m2 plots in a tallgrass prairie in Galveston County, Texas, in spring 2000. Plots were assigned a fire (no burn, one time burn [2000], two time burn [2000, 2001]) and fertilization treatment (none, NPK addition) in a full factorial design. Fertilization treatments allowed us to examine the effects of fire at a different level of productivity. We measured plant cover by species and sampled arthropods with sweep nets during the 2001 growing season. Path analysis indicated that fertilization reduced while annual fires increased arthropod diversity via increases and decreases in woody plant abundance, respectively. There was no direct effect of fire on arthropod diversity or abundance. Diptera and Homoptera exhibited particularly strong positive responses to fires. Lepidoptera had a negative response to nutrient enrichment. Overall, the negative effects of fire on the arthropod community were minor in contrast to the strong positive indirect effects of small-scale burning on arthropod diversity if conservation of particular taxa is not a priority. The same fire regime that minimized woody plant invasion also maximized arthropod diversity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Midland Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1674/0003-0031(2007)157[92:ROPACT]2.0.CO;2","issn":"00030031","usgsCitation":"Hartley, M., Rogers, W., Siemann, E., and Grace, J., 2007, Responses of prairie arthropod communities to fire and fertilizer: Balancing plant and arthropod conservation: American Midland Naturalist, v. 157, no. 1, p. 92-105, https://doi.org/10.1674/0003-0031(2007)157[92:ROPACT]2.0.CO;2.","startPage":"92","endPage":"105","numberOfPages":"14","costCenters":[],"links":[{"id":213295,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1674/0003-0031(2007)157[92:ROPACT]2.0.CO;2"},{"id":240907,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"157","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaaa7e4b0c8380cd8645c","contributors":{"authors":[{"text":"Hartley, M.K.","contributorId":19375,"corporation":false,"usgs":true,"family":"Hartley","given":"M.K.","email":"","affiliations":[],"preferred":false,"id":438711,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rogers, W.E.","contributorId":66443,"corporation":false,"usgs":true,"family":"Rogers","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":438713,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Siemann, E.","contributorId":43575,"corporation":false,"usgs":true,"family":"Siemann","given":"E.","email":"","affiliations":[],"preferred":false,"id":438712,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Grace, J.","contributorId":88459,"corporation":false,"usgs":true,"family":"Grace","given":"J.","affiliations":[],"preferred":false,"id":438714,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
