Because black-footed ferrets are specialized predators of prairie dogs (Cynomys sp.), a better understanding of how black-footed ferrets select resources might provide insight into how best to identify and manage reintroduction sites. We monitored ferret resource selection at two reintroduction sites with different densities of prairie dog populations-one that contained a high density of prairie dogs (Conata Basin, South Dakota) and one that was lower (UL Bend, Montana). We evaluated support for hypotheses about ferret resource selection as related to the distribution of active burrows used by black-tailed prairie dogs (Cynomys ludovicianus), interactions between ferrets, and habitat edge effects. We found support for all three factors within both populations; however, they affected ferret resource selection differently at each site. Ferrets at Conata Basin tended to select areas with high prairie dog burrow density, closer to the colony edge, and that overlapped other ferret ranges. In contrast, ferrets at UL Bend tended not to select areas of high active prairie dog burrow density, avoided areas close to edge habitat, and females avoided areas occupied by other ferrets. The differences observed between the two sites might be best explained by prairie dog densities, which were higher at Conata Basin (119.3 active burrows per ha) than at UL Bend (44.4 active burrows per ha). Given the positive growth of ferret populations at Conata Basin, management that increases the density of prairie dogs might enhance ferret success within natural areas. To achieve long-term recovery of ferrets in the wild, conservationists should increasingly work across and outside natural area boundaries to increase prairie dog populations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Natural Areas Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.3375/043.031.0304","issn":"08858608","usgsCitation":"Jachowski, D., Millspaugh, J., Biggins, E., Livieri, T., Matchett, M., and Rittenhouse, C., 2011, Resource selection by black-footed ferrets in South Dakota and Montana: Natural Areas Journal, v. 31, no. 3, p. 218-225, https://doi.org/10.3375/043.031.0304.","startPage":"218","endPage":"225","numberOfPages":"8","costCenters":[],"links":[{"id":246333,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218334,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3375/043.031.0304"}],"volume":"31","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa9fee4b0c8380cd860b1","contributors":{"authors":[{"text":"Jachowski, D.S.","contributorId":67309,"corporation":false,"usgs":true,"family":"Jachowski","given":"D.S.","email":"","affiliations":[],"preferred":false,"id":454543,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Millspaugh, J.J.","contributorId":99105,"corporation":false,"usgs":true,"family":"Millspaugh","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":454546,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Biggins, E.","contributorId":88303,"corporation":false,"usgs":true,"family":"Biggins","given":"E.","email":"","affiliations":[],"preferred":false,"id":454544,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Livieri, T.M.","contributorId":96910,"corporation":false,"usgs":true,"family":"Livieri","given":"T.M.","affiliations":[],"preferred":false,"id":454545,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Matchett, Marc R.","contributorId":53121,"corporation":false,"usgs":true,"family":"Matchett","given":"Marc R.","affiliations":[],"preferred":false,"id":454542,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Rittenhouse, C.D.","contributorId":101499,"corporation":false,"usgs":true,"family":"Rittenhouse","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":454547,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Instead, these processes are often approximated from laboratory, numerical, and theoretical studies or inferred from observations of the resultant sediment deposits. Here Delft3D, a three-dimensional numerical model, is used to simulate the inundation and sediment transport of a tsunami similar in magnitude to the 26 December 2004 Indian Ocean tsunami over one measured and three idealized morphologies. The model is first shown to match well the observations taken at Kuala Meurisi, Sumatra, and then used to examine in detail the processes that occur during the tsunami. The model predicts that at a given cross-shore location the onshore flow accelerates rapidly to a maximum as the wavefront passes, and then gradually decelerates before reversing direction and flowing offshore. The onshore flow does not tend to zero everywhere at maximum inundation, but instead flow reversal occurs near the shoreline even as the wavefront continues to inundate landward. While some sediment is eroded by the passing wavefront, the suspension of sandy sediment is dominated by the long-duration, high-velocity backwash that occurs along the beach face and offshore of the shoreline. Some of the sediment suspended during backwash is advected shoreward by the subsequent wave, creating large spatial gradients in the suspended sediment concentrations, which may not be in equilibrium with the local hydrodynamics. The inundation and transport of sediment during a tsunami can be affected by complexities in the morphological profile and interactions between multiple waves, and many of the hydrodynamic and sediment transport processes predicted here are similar to analogous processes previously observed in the swash zone.

Typically, the availability of patches changes over time, and recommendations must be made dynamically.

In this paper, we develop an efficient algorithm for adaptively making recommendations for dynamic conservation planning, and prove that it obtains near-optimal performance.

We explore the relative effects of these processes on the maintenance of wide observed body size variation in stream-dwelling brook trout (Salvelinus fontinalis). Based on the analyses of multiple recaptures of individual fish, it appears that size distributions are largely determined by the maintenance of early size variation. We found no evidence for size-dependent compensatory growth (which would reduce size variation) and found no indication that size-dependent survival substantially influenced body size distributions. Depensatory growth (faster growth by larger individuals) reinforced early size variation, but was relatively strong only during the first sampling interval (age-0, fall). Maternal decisions on the timing and location of spawning could have a major influence on early, and as our results suggest, later (>age-0) size distributions. If this is the case, our estimates of heritability of body size (body length=0.25) will be dominated by processes that generate and maintain early size differences. As a result, evolutionary responses to environmental change that are mediated by body size may be largely expressed via changes in the timing and location of reproduction. Published 2011.

During successive summer experiments – referred to as “Winchester” (2007) and “Big Rusty” (2008) - acetate was added to the aquifer to stimulate the activity of indigenous dissimilatory metal-reducing bacteria capable of reductively immobilizing uranium. The two experiments differed in the length of injection (31 vs. 110 days), the maximum concentration of acetate (5 vs. 30 mM), and the extent to which iron reduction (“Winchester”) or sulfate reduction (“Big Rusty”) was the predominant metabolic process. In both cases, rapid removal of U(VI) from groundwater occurred at calcium concentrations (6 mM) and carbonate alkalinities (8&nbsp;meq/L) where Ca-UO</span><sub>2</sub><span>-CO</span><sub>3</sub><span>&nbsp;ternary complexes constitute &gt;90% of uranyl species in groundwater. Complete consumption of acetate and increased alkalinity (&gt;30 meq/L) accompanying the onset of sulfate reduction corresponded to temporary increases in U(VI); however, by increasing acetate concentrations in excess of available sulfate (10 mM), low U(VI) concentrations (0.1–0.05 μM) were achieved for extended periods of time (&gt;140 days). Uniform delivery of acetate during “Big Rusty” was impeded due to decreases in injection well permeability, likely resulting from biomass accumulation and carbonate and sulfide mineral precipitation. Such decreases were not observed during the short-duration “Winchester” experiment. Terminal restriction fragment length polymorphism (TRFLP) analysis of 16S rRNA genes demonstrated that&nbsp;</span><i>Geobacter</i><span>&nbsp;sp. and&nbsp;</span><i>Geobacter</i><span>-like strains dominated the groundwater community profile during iron reduction, with&nbsp;</span><sup>13</sup><span>C stable isotope probing (SIP) results confirming these strains were actively utilizing acetate to replicate their genome during the period of optimal U(VI) removal.

For all four wintering adults use of refuse-disposal sites was evident or strongly suggested.

We developed a strategy for rapid construction of a regional DNA-barcode reference library and used the caddisflies (Trichoptera) of the Great Smoky Mountains National Park (GSMNP) as a model. Nearly 1000 cytochrome c oxidase subunit I (COI) sequences, representing 209 caddisfly species previously recorded from GSMNP, were obtained from the global Trichoptera Barcode of Life campaign. Most of these sequences were collected from outside the GSMNP area. Another 645 COI sequences, representing 80 species, were obtained from specimens collected in a 3-d bioblitz (short-term, intense sampling program) in GSMNP. The joint collections provided barcode coverage for 212 species, 91% of the GSMNP fauna. Inclusion of samples from other localities greatly expedited construction of the regional DNA-barcode reference library. This strategy increased intraspecific divergence and decreased average distances to nearest neighboring species, but the DNA-barcode library was able to differentiate 93% of the GSMNP Trichoptera species examined. Global barcoding projects will aid construction of regional DNA-barcode libraries, but local surveys make crucial contributions to progress by contributing rare or endemic species and full-length barcodes generated from high-quality DNA. DNA taxonomy is not a goal of our present work, but the investigation of COI divergence patterns in caddisflies is providing new insights into broader biodiversity patterns in this group and has directed attention to various issues, ranging from the need to re-evaluate species taxonomy with integrated morphological and molecular evidence to the necessity of an appropriate interpretation of barcode analyses and its implications in understanding species diversity (in contrast to a simple claim for barcoding failure).</p>","language":"English","doi":"10.1899/10-010.1","issn":"08873593","usgsCitation":"Zhou, X., Robinson, J., Geraci, C., Parker, C., Flint, O., Etnier, D., Ruiter, D., DeWalt, R., Jacobus, L., and Hebert, P., 2011, Accelerated construction of a regional DNA-barcode reference library: Caddisflies (Trichoptera) in the Great Smoky Mountains National Park: Journal of the North American Benthological Society, v. 30, no. 1, p. 131-162, https://doi.org/10.1899/10-010.1.","startPage":"131","endPage":"162","numberOfPages":"32","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":475145,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://www.bioone.org/doi/10.1899/10-010.1","text":"External Repository"},{"id":244237,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216373,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1899/10-010.1"}],"volume":"30","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e666e4b0c8380cd473c0","contributors":{"authors":[{"text":"Zhou, X.","contributorId":91330,"corporation":false,"usgs":true,"family":"Zhou","given":"X.","email":"","affiliations":[],"preferred":false,"id":451836,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Robinson, J.L.","contributorId":13283,"corporation":false,"usgs":true,"family":"Robinson","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":451829,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Geraci, C.J.","contributorId":38807,"corporation":false,"usgs":true,"family":"Geraci","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":451831,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Parker, C.R.","contributorId":21892,"corporation":false,"usgs":true,"family":"Parker","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":451830,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Flint, O.S.

Under seasonal and decadal air temperature variations, permafrost temperature changes control the exchanges between groundwater and surface water. A coupled heat transport and groundwater flow model, SUTRA, was modified to simulate groundwater flow and heat transport in the subsurface containing permafrost. The northern central Tibet Plateau was used as an example of model application. Modeling results show that in a yearly cycle, groundwater flow occurs in the active layer from May to October. Maximum groundwater discharge to the surface lags the maximum subsurface temperature by two months. Under an increasing air temperature scenario of 3C per 100 years, over the initial 40-year period, the active layer thickness can increase by three-fold. Annual groundwater discharge to the surface can experience a similar three-fold increase in the same period. An implication of these modeling results is that with increased warming there will be more groundwater flow in the active layer and therefore increased groundwater discharge to rivers. However, this finding only holds if sufficient upgradient water is available to replenish the increased discharge. Otherwise, there will be an overall lowering of the water table in the recharge portion of the catchment.

Although impractical to be quantified directly, a tsunami source can be estimated by different methods based on a variety of measurements provided by deep-ocean tsunameters, seismometers, GPS, and other advanced instruments, some in real time, some in post real-time. Here we assess these different sources of the devastating March 11, 2011 Japan tsunami by model-data comparison for generation, propagation and inundation in the near field of Japan. This study provides a comparative study to further understand the advantages and shortcomings of different methods that may be potentially used in real-time warning and forecast of tsunami hazards, especially in the near field. The model study also highlights the critical role of deep-ocean tsunami measurements for high-quality tsunami forecast, and its combination with land GPS measurements may lead to better understanding of both the earthquake mechanisms and tsunami generation process.</span></p>","largerWorkType":{"id":24,"text":"Conference Paper"},"largerWorkTitle":"OCEANS'11 - MTS/IEEE Kona, Program Book","largerWorkSubtype":{"id":19,"text":"Conference Paper"},"conferenceTitle":"MTS/IEEE Kona Conference, OCEANS'11","conferenceDate":"September 19-22, 2011","conferenceLocation":"Kona, HI","language":"English","publisher":"IEEE","doi":"10.23919/OCEANS.2011.6107294","isbn":"9781457714276","usgsCitation":"Wei, Y., Titov, V., Newman, A., Hayes, G., Tang, L., and Chamberlin, C., 2011, Near-field hazard assessment of March 11, 2011 Japan Tsunami sources inferred from different methods, <i>in</i> OCEANS'11 - MTS/IEEE Kona, Program Book, Kona, HI, September 19-22, 2011, 9 p., https://doi.org/10.23919/OCEANS.2011.6107294.","productDescription":"9 p.","costCenters":[],"links":[{"id":243070,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Japan","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"MultiPolygon\",\"coordinates\":[[[[134.63843,34.14923],[134.76638,33.80633],[134.20342,33.20118],[133.79295,33.52199],[133.28027,33.28957],[133.01486,32.70457],[132.36311,32.98938],[132.37118,33.46364],[132.92437,34.0603],[133.49297,33.94462],[133.90411,34.36493],[134.63843,34.14923]]],[[[140.97639,37.14207],[140.59977,36.34398],[140.77407,35.84288],[140.25328,35.13811],[138.97553,34.6676],[137.2176,34.60629],[135.79298,33.46481],[135.12098,33.84907],[135.07943,34.59654],[133.34032,34.37594],[132.15677,33.90493],[130.98614,33.88576],[132.00004,33.14999],[131.33279,31.45035],[130.68632,31.02958],[130.20242,31.41824],[130.44768,32.31947],[129.81469,32.61031],[129.40846,33.29606],[130.35394,33.60415],[130.87845,34.23274],[131.88423,34.74971],[132.61767,35.43339],[134.6083,35.73162],[135.67754,35.52713],[136.72383,37.30498],[137.39061,36.82739],[138.8576,37.82748],[139.4264,38.21596],[140.05479,39.43881],[139.88338,40.56331],[140.30578,41.19501],[141.36897,41.37856],[141.91426,39.99162],[141.8846,39.18086],[140.95949,38.174],[140.97639,37.14207]]],[[[143.91016,44.1741],[144.61343,43.96088],[145.32083,44.38473],[145.54314,43.26209],[144.05966,42.98836],[143.18385,41.99521],[141.61149,42.67879],[141.06729,41.58459],[139.95511,41.56956],[139.81754,42.56376],[140.31209,43.33327],[141.38055,43.38882],[141.67195,44.77213],[141.96764,45.55148],[143.14287,44.51036],[143.91016,44.1741]]]]},\"properties\":{\"name\":\"Japan\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a63dee4b0c8380cd72749","contributors":{"authors":[{"text":"Wei, Y.","contributorId":9502,"corporation":false,"usgs":true,"family":"Wei","given":"Y.","email":"","affiliations":[],"preferred":false,"id":449971,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Titov, V.V.","contributorId":48752,"corporation":false,"usgs":true,"family":"Titov","given":"V.V.","email":"","affiliations":[],"preferred":false,"id":449973,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Newman, A.","contributorId":32791,"corporation":false,"usgs":true,"family":"Newman","given":"A.","affiliations":[],"preferred":false,"id":449972,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hayes, G.","contributorId":81349,"corporation":false,"usgs":true,"family":"Hayes","given":"G.","affiliations":[],"preferred":false,"id":449975,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Tang, Liujuan","contributorId":34045,"corporation":false,"usgs":true,"family":"Tang","given":"Liujuan","email":"","affiliations":[],"preferred":false,"id":449976,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Chamberlin, C.","contributorId":76197,"corporation":false,"usgs":true,"family":"Chamberlin","given":"C.","email":"","affiliations":[],"preferred":false,"id":449974,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We constructed a 3-stage life-history matrix model to estimate population growth rate (λ) and assessed the relative importance of adult survival and other life-history parameters to population growth through elasticity and sensitivity analysis. Annual adult survival at 5 maternity colonies monitored from 2001 to 2005 was estimated at 0.79 (95% confidence interval [95%&nbsp;</span><i>CI</i><span>] = 0.77–0.82). Adult survival varied by year and roost, with low survival during an extreme drought year, a finding with negative implications for bat populations because of the likelihood of increasing drought in western North America due to global climate change. Adult survival during winter was higher than in summer, and mean life expectancies calculated from survival estimates were lower than maximum longevity records. We modeled adult survival with recruitment parameter estimates from the same population. The study population was growing (λ = 1.096; 95%&nbsp;</span><i>CI</i><span>&nbsp;= 1.057–1.135). Adult survival was the most important demographic parameter for population growth. Growth clearly had the highest elasticity to adult survival, followed by juvenile survival and adult fecundity (approximately equivalent in rank). Elasticity was lowest for fecundity of yearlings.

Our results provide support for a physico-chemical model of coral biomineralization, and imply that Mg2+ substitutes directly for Ca2+ in biogenic aragonite. Recent studies have identified Rayleigh fractionation as an important influence on the elemental composition of coral skeletons. Daily, seasonal and interannual variations in the amount of aragonite precipitated by corals from each “batch” of calcifying fluid can explain why the temperature dependencies of elemental ratios in coral skeleton differ from those of abiogenic aragonites, and are highly variable among individual corals. On the basis of this new insight into the origin of “vital effects” in coral skeleton, we developed a Rayleigh-based, multi-element approach to coral thermometry. Temperature is resolved from the Rayleigh fractionation signal by combining information from multiple element ratios (e.g., Mg/Ca, Sr/Ca, Ba/Ca) to produce a mathematically over-constrained system of Rayleigh equations. Unlike conventional coral thermometers, this approach does not rely on an initial calibration of coral skeletal composition to an instrumental temperature record. Rather, considering coral skeletogenesis as a biologically mediated, physico-chemical process provides a means to extract temperature information from the skeleton composition using the Rayleigh equation and a set of experimentally determined partition coefficients. Because this approach is based on a quantitative understanding of the mechanism that produces the “vital effect” it should be possible to apply it both across scleractinian species and to corals growing in vastly different environments. Where instrumental temperature records are available, a Rayleigh-based framework allows the effects of stress on coral calcification to be identified on the basis of anomalies in the skeletal composition.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2011.01.010","issn":"00167037","usgsCitation":"Gaetani, G., Cohen, A., Wang, Z., and Crusius, J., 2011, Rayleigh-based, multi-element coral thermometry: A biomineralization approach to developing climate proxies: Geochimica et Cosmochimica Acta, v. 75, no. 7, p. 1920-1932, https://doi.org/10.1016/j.gca.2011.01.010.","productDescription":"13 p.","startPage":"1920","endPage":"1932","costCenters":[{"id":680,"text":"Woods Hole Science Center","active":false,"usgs":true}],"links":[{"id":243834,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215995,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2011.01.010"}],"volume":"75","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a955be4b0c8380cd81979","contributors":{"authors":[{"text":"Gaetani, G.A.","contributorId":77763,"corporation":false,"usgs":true,"family":"Gaetani","given":"G.A.","affiliations":[],"preferred":false,"id":448246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cohen, A.L.","contributorId":68131,"corporation":false,"usgs":true,"family":"Cohen","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":448245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wang, Z.","contributorId":67976,"corporation":false,"usgs":true,"family":"Wang","given":"Z.","affiliations":[],"preferred":false,"id":448244,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crusius, John 0000-0003-2554-0831 jcrusius@usgs.gov","orcid":"https://orcid.org/0000-0003-2554-0831","contributorId":2155,"corporation":false,"usgs":true,"family":"Crusius","given":"John","email":"jcrusius@usgs.gov","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":448243,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Models of soil development suggest that the nature of nutrient limitation changes over the course of ecosystem development, transitioning from nitrogen (N) limitation in ‘young’ sites to phosphorus (P) limitation in ‘old’ sites. However, previous research has focused primarily on plant responses to added nutrients, and the applicability of nutrient limitation-soil development models to belowground processes has not been thoroughly investigated. Here, we assessed the effects of nutrients on soil C cycling in three different forests that occupy a 4 million year substrate age chronosequence where tree growth is N limited at the youngest site, co-limited by N and P at the intermediate-aged site, and P limited at the oldest site. Our goal was to use short-term laboratory soil C manipulations (using&nbsp;</span><sup>14</sup><span>C-labeled substrates) and longer-term intact soil core incubations to compare belowground responses to fertilization with aboveground patterns. When nutrients were applied with labile C (sucrose), patterns of microbial nutrient limitation were similar to plant patterns: microbial activity was limited more by N than by P in the young site, and P was more limiting than N in the old site. However, in the absence of C additions, increased respiration of native soil organic matter only occurred with simultaneous additions of N and P. Taken together, these data suggest that altered nutrient inputs into ecosystems could have dissimilar effects on C cycling above- and belowground, that nutrients may differentially affect of the fate of different soil C pools, and that future changes to the net C balance of terrestrial ecosystems will be partially regulated by soil nutrient status.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s10533-010-9522-6","issn":"01682563","usgsCitation":"Reed, S.C., Vitousek, P., and Cleveland, C., 2011, Are patterns in nutrient limitation belowground consistent with those aboveground: Results from a 4 million year chronosequence: Biogeochemistry, v. 106, no. 3, p. 323-336, https://doi.org/10.1007/s10533-010-9522-6.","productDescription":"14 p.","startPage":"323","endPage":"336","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":243972,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216125,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10533-010-9522-6"}],"volume":"106","issue":"3","noUsgsAuthors":false,"publicationDate":"2010-09-23","publicationStatus":"PW","scienceBaseUri":"5059ed5ee4b0c8380cd4977f","contributors":{"authors":[{"text":"Reed, Sasha C. 0000-0002-8597-8619 screed@usgs.gov","orcid":"https://orcid.org/0000-0002-8597-8619","contributorId":462,"corporation":false,"usgs":true,"family":"Reed","given":"Sasha","email":"screed@usgs.gov","middleInitial":"C.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":451235,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vitousek, P.M.","contributorId":102208,"corporation":false,"usgs":true,"family":"Vitousek","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":451236,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cleveland, C.C.","contributorId":62387,"corporation":false,"usgs":true,"family":"Cleveland","given":"C.C.","email":"","affiliations":[],"preferred":false,"id":451234,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The stable hydrogen isotope composition of hair has been used in ecological studies to track migrations of mammals as well as for forensic and archaeological purposes to determine the provenance of human remains or the recent geographic life trajectory of living people. Measurement of the total hydrogen isotopic composition of a hair sample yields a composite value comprised of both metabolically informative, non-exchangeable hydrogen and exchangeable hydrogen, with the latter reflecting ambient or sample preparation conditions. Neither of these attributes is directly measurable, and the non-exchangeable hydrogen composition is obtained by estimation using a commonly applied mathematical expression incorporating sample measurements obtained from two distinct equilibration procedures. This commonly used approach treats the fraction of exchangeable hydrogen as a mixing ratio, with a minimal procedural fractionation factor assumed to be close or equal to 1. Instead, we propose to use full molar ratios to derive an expression for the non-exchangeable hydrogen composition explicitly as a function of both the procedural fractionation factor α and the molar hydrogen exchange fraction f<sub>E</sub>. We apply these derivations in a longitudinal study of a hair sample and demonstrate that the molar hydrogen exchange fraction f<sub>E</sub> should, like the procedural fractionation factor α, be treated as a process-dependent parameter, i.e. a reaction-specific constant. This is a counter-intuitive notion given that maximum theoretical values for the molar hydrogen exchange fraction f<sub>E</sub> can be calculated that are arguably protein-type specific and, as such, f<sub>E</sub> could be regarded as a compound-specific constant. We also make some additional suggestions for future approaches to determine the non-exchangeable hydrogen composition of hair and the use of standards.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Rapid Communications in Mass Spectrometry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/rcm.4854","issn":"09514198","usgsCitation":"Landwehr, J., Meier-Augenstein, W., and Kemp, H., 2011, A counter-intuitive approach to calculating non-exchangeable <sup>2</sup>H isotopic composition of hair: treating the molar exchange fraction f<sub>E</sub> as a process-related rather than compound-specific variable: Rapid Communications in Mass Spectrometry, v. 25, no. 2, p. 301-306, https://doi.org/10.1002/rcm.4854.","productDescription":"6 p.","startPage":"301","endPage":"306","costCenters":[{"id":633,"text":"Water Resources National Research Program","active":false,"usgs":true}],"links":[{"id":216291,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/rcm.4854"},{"id":244154,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-12-28","publicationStatus":"PW","scienceBaseUri":"5059e39de4b0c8380cd46125","contributors":{"authors":[{"text":"Landwehr, J.M.","contributorId":39815,"corporation":false,"usgs":true,"family":"Landwehr","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":452971,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meier-Augenstein, W.","contributorId":29664,"corporation":false,"usgs":true,"family":"Meier-Augenstein","given":"W.","affiliations":[],"preferred":false,"id":452970,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kemp, H.F.","contributorId":41241,"corporation":false,"usgs":true,"family":"Kemp","given":"H.F.","email":"","affiliations":[],"preferred":false,"id":452972,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Alaska and Canada margins are mantled with thick, growth-faulted sediment prisms, and the Chukchi Borderland contains only a thin veneer of sediment. The rift-margin strata of Alaska and Canada reflect the tectonics and sediment dispersal systems of adjacent continental regions whereas the Chukchi Borderland was tectonically isolated from these sediment dispersal systems. Along the eastern Alaska–southern Canada margin, termed herein the ‘Canning–Mackenzie deformed margin’, the rifted margin is deformed by ongoing Brooks Range tectonism. Additional contractional structures occur in a gravity fold belt that may be present along the entire Alaska and Canada margins of the Canada Basin. Source-rock data inboard of the rift shoulders and regional palaeogeographic reconstructions suggest three potential source-rock intervals: Lower Cretaceous (Hauterivian–Albian), Upper Cretaceous (mostly Turonian) and Lower Palaeogene. Burial history modelling indicates favourable timing for generation from all three intervals beneath the Alaska and Canada passive margins, and an active petroleum system has been documented in the Canning–Mackenzie deformed margin. Assessment of undiscovered petroleum resources indicates the greatest potential in the Canning–Mackenzie deformed margin and significant potential in the Canada and Alaska passive margins.</span></p>","language":"English","publisher":"Geological Society of London","doi":"10.1144/M35.34","issn":"04354052","usgsCitation":"Houseknecht, D., and Bird, K.J., 2011, Geology and petroleum potential of the rifted margins of the Canada Basin: Geological Society Memoir, no. 35, p. 509-526, https://doi.org/10.1144/M35.34.","productDescription":"18 p.","startPage":"509","endPage":"526","ipdsId":"IP-013993","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":246273,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218276,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1144/M35.34"}],"country":"Canada","otherGeospatial":"Canada Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -153.6328125,\n              73.72659470212253\n            ],\n            [\n              -154.68749999999997,\n              69.28725695167886\n            ],\n            [\n              -127.265625,\n              68.26938680456564\n            ],\n            [\n              -108.6328125,\n              69.77895177646761\n            ],\n            [\n              -106.875,\n              73.92246884621463\n            ],\n            [\n              -79.1015625,\n              81.09321385260837\n            ],\n            [\n              -75.9375,\n              83.4803661137381\n            ],\n            [\n              -133.9453125,\n              83.599030708362\n            ],\n            [\n              -170.15625,\n              79.87429692631282\n            ],\n            [\n              -169.1015625,\n              74.1160468394894\n            ],\n            [\n              -152.2265625,\n              74.01954331150228\n            ],\n            [\n              -153.6328125,\n              73.72659470212253\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","issue":"35","noUsgsAuthors":false,"publicationDate":"2011-08-05","publicationStatus":"PW","scienceBaseUri":"5059f46ae4b0c8380cd4bd06","contributors":{"authors":[{"text":"Houseknecht, D.W. 0000-0002-9633-6910","orcid":"https://orcid.org/0000-0002-9633-6910","contributorId":33695,"corporation":false,"usgs":true,"family":"Houseknecht","given":"D.W.","affiliations":[],"preferred":false,"id":454788,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bird, Kenneth J. kbird@usgs.gov","contributorId":1015,"corporation":false,"usgs":true,"family":"Bird","given":"Kenneth","email":"kbird@usgs.gov","middleInitial":"J.","affiliations":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"preferred":true,"id":454789,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Recent work suggests that 5 elevated CO2 and temperature warming will increase organic matter productivity and the ability of marshes to survive sea level rise. However, we find that organic decomposition rates increase by about 12% per degree of warming. Our measured temperature sensitivity is similar to studies from terrestrial systems, twice as high as the response of salt marsh productivity to temperature warming, and roughly equivalent to the productivity response associated with elevated CO2 10 in C3 marsh plants. Therefore, enhanced CO2 and warmer temperatures may actually make marshes less resilient to sea level rise, and tend to promote a release of soil carbon. Simple projections indicate that elevated temperatures will increase rates of sea level rise more than any acceleration in organic matter accumulation, suggesting the possibility of a positive feedback between 15 climate, sea level rise, and carbon emissions in coastal environment</p>","language":"English","publisher":"Copernicus","doi":"10.5194/bgd-8-707-2011","issn":"18106277","usgsCitation":"Kirwan, M.L., and Blum, L.K., 2011, Enhanced decomposition offsets enhanced productivity and soil carbon accumulation in coastal wetlands responding to climate change: Biogeosciences Discussions, v. 8, no. 1, p. 707-722, https://doi.org/10.5194/bgd-8-707-2011.","productDescription":"16 p.","startPage":"707","endPage":"722","numberOfPages":"16","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":475109,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/bgd-8-707-2011","text":"Publisher Index Page"},{"id":246356,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a096de4b0c8380cd51ee2","contributors":{"authors":[{"text":"Kirwan, Matt L.","contributorId":189205,"corporation":false,"usgs":false,"family":"Kirwan","given":"Matt","middleInitial":"L.","affiliations":[],"preferred":false,"id":453583,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blum, L.

Four explanatory variables (fish consumption, male age, winter, and body size) were evaluated as to whether they influenced five response variables associated with gut characteristics of Mallards. Response variables were lower gastro-intestinal tract mass (LGIT), dry liver mass, dry gizzard mass, small intestine length, and ceca length. Diets of Mallards were comprised primarily of Rainbow Smelt (Osmerus mordax) and concomitantly variation in gizzard mass was small. LGIT mass of juveniles was larger than that of adults, greater for those that consumed fish, and greater during the coldest and snowiest winter. Liver mass and small intestine length of Mallards that consumed fish were greater than those that did not. Mallards may maintain lengthy intestines to increase digestive efficiency. Gut size variation was not entirely attributable to dietary composition but also influenced by body size and environmental conditions such that over-winter survival is maximized.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Waterbirds","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1675/063.034.0107","issn":"15244695","usgsCitation":"Olsen, R., Cox, R.R., Afton, A., and Ankney, C., 2011, Diet and gut morphology of male mallards during winter in North Dakota: Waterbirds, v. 34, no. 1, p. 59-69, https://doi.org/10.1675/063.034.0107.","startPage":"59","endPage":"69","numberOfPages":"11","costCenters":[],"links":[{"id":216278,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1675/063.034.0107"},{"id":244141,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"34","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00cbe4b0c8380cd4f90c","contributors":{"authors":[{"text":"Olsen, R.E.","contributorId":85125,"corporation":false,"usgs":true,"family":"Olsen","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":451990,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cox, R.

Satellite magnetic and gravity data were used for quality control of the long wavelengths of the new compilations. The new Circum-Arctic digital compilations of magnetic, gravity and some of their derivatives have been analyzed together with other freely available regional and global data and models in order to provide a consistent view of the tectonically complex Arctic basins and surrounding continents. Sharp, linear contrasts between deeply buried basement blocks with different magnetic properties and densities that can be identified on these maps can be used, together with other geological and geophysical information, to refine the tectonic boundaries of the Arctic domain.</span></p>","language":"English","publisher":"Geological Society of

As organisms have evolved mutualistic and synergistic relationships, the loss of one or a few species can have a much wider environmental impact. Since much pollination is facilitated by bees, the reported colony collapse disorder has many worried of widespread agricultural fallout and thus deleterious impact on human foodstocks. In this Feature, Spivak et al. review what is known of the present state of bee populations and provide information on how to mitigate and reverse the trend.</p></div>","language":"English","publisher":"American Chemical Society","doi":"10.1021/es101468w","issn":"0013936X","usgsCitation":"Spivak, M., Mader, E., Vaughan, M., and Euliss, N.H., 2011, The plight of the bees: Environmental Science & Technology, v. 45, no. 1, p. 34-38, https://doi.org/10.1021/es101468w.","productDescription":"5 p.","startPage":"34","endPage":"38","costCenters":[],"links":[{"id":244106,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216245,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es101468w"}],"volume":"45","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-09-14","publicationStatus":"PW","scienceBaseUri":"505bae9ee4b08c986b324209","contributors":{"authors":[{"text":"Spivak, M.","contributorId":27703,"corporation":false,"usgs":true,"family":"Spivak","given":"M.","email":"","affiliations":[],"preferred":false,"id":451779,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mader, E.","contributorId":82154,"corporation":false,"usgs":true,"family":"Mader","given":"E.","email":"","affiliations":[],"preferred":false,"id":451782,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vaughan, M.","contributorId":77703,"corporation":false,"usgs":true,"family":"Vaughan","given":"M.","email":"","affiliations":[],"preferred":false,"id":451781,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Euliss, Ned H.
