Measured in samples from bedrock fluvial terraces, 10-beryllium shows that both the Susquehanna and Potomac Rivers incised 10- to 20-meter-deep gorges along steep, convex lower reaches during the last glacial cycle. This short-lived pulse of unusually rapid downcutting ended by 13,000 to 14,000 years ago.

In this study, we examine the effects of some of these mesoscale features on local turbulent flux measurements; most notably, the formation of valley/mountain flows and mountain lee-side waves. The valley/mountain flows created local non-stationarities in the wind flow caused by the passage of a lee-side convergence zone (LCZ) in which upslope and downslope flows met in the vicinity of the measurement tower. During June–August, 2001, possible lee-side convergences were flagged for ∼26% of all half-hour daytime flux measurement periods. However, there was no apparent loss of flux during these periods. On some relatively stable, summer nights, turbulence (designated via<span>&nbsp;</span><i>σ</i><sub><i>w</i></sub>), and scalar fluctuations (temperature and CO<sub>2</sub>, for example) exhibited periodicities that appeared congruent with passage of low frequency gravity waves (<i>τ</i><span>&nbsp;</span>∼ 20&nbsp;min). Spectral peaks at 0.0008&nbsp;Hz (20&nbsp;min) in both vertical velocity and scalar spectra were observed and indicated that 25–50% of the total scalar covariances were accounted for by the low frequency waves. During some periods of strong westerly winds (predominantly in winter), large mountain gravity waves were observed to form. Typically, the flux tower resided within a region of downslope “shooting flow”, which created high turbulence, but had no detrimental effect on local flux measurements based on valid turbulence statistics and nearly complete energy budget closure. Periodically, we found evidence for re-circulating, rotor winds in the simultaneous time series of wind data from the Ameriflux tower site and a second meteorological site situated 8&nbsp;km upslope and to the West. Only 14% of the half-hour time periods that we examined for a 4 month period in the winter of 2000–2001 indicated the possible existence of rotor winds. On average, energy budget closure was ∼20% less during periods with rotor occurrence compared to those without.</p><p>Results from this study demonstrate that the potential exists for relatively rare, yet significant influences of mesoscale wind flow patterns on the local half-hour flux measurements at this site.

This study documents gene flow on a landscape level from creeping bentgrass (Agrostis stolonifera L.), one of the first wind-pollinated, perennial, and highly outcrossing transgenic crops being developed for commercial use. Most of the gene flow occurred within 2 km in the direction of prevailing winds. The maximal gene flow distances observed were 21 km and 14 km in sentinel and resident plants, respectively, that were located in primarily nonagronomic habitats. The selectable marker used in these studies was the CP4 EPSPS gene derived from Agrobacterium spp. strain CP4 that encodes 5-enol-pyruvylshikimate-3-phosphate synthase and confers resistance to glyphosate herbicide. Evidence for gene flow to 75 of 138 sentinel plants of A. stolonifera and to 29 of 69 resident Agrostis plants was based on seedling progeny survival after spraying with glyphosate in greenhouse assays and positive TraitChek, PCR, and sequencing results. Additional studies are needed to determine whether introgression will occur and whether it will affect the ecological fitness of progeny or the structure of plant communities in which transgenic progeny may become established.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the National Academy of Sciences of the United States of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1073/pnas.0405154101","issn":"00278424","usgsCitation":"Watrud, L., Lee, E., Fairbrother, A., Burdick, C., Reichman, J., Bollman, M., Storm, M., King, G., and Van De Water, P.K., 2004, Evidence for landscape-level, pollen-mediated gene flow from genetically modified creeping bentgrass with CP4 EPSPS as a marker: Proceedings of the National Academy of Sciences of the United States of America, v. 101, no. 40, p. 14533-14538, https://doi.org/10.1073/pnas.0405154101.","startPage":"14533","endPage":"14538","numberOfPages":"6","costCenters":[],"links":[{"id":478191,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/521937","text":"External Repository"},{"id":208475,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1073/pnas.0405154101"},{"id":234236,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"101","issue":"40","noUsgsAuthors":false,"publicationDate":"2004-09-24","publicationStatus":"PW","scienceBaseUri":"505a0d44e4b0c8380cd52ef0","contributors":{"authors":[{"text":"Watrud, L.S.","contributorId":10963,"corporation":false,"usgs":true,"family":"Watrud","given":"L.S.","email":"","affiliations":[],"preferred":false,"id":409809,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lee, E.H.","contributorId":59996,"corporation":false,"usgs":true,"family":"Lee","given":"E.H.","email":"","affiliations":[],"preferred":false,"id":409813,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fairbrother, A.","contributorId":25500,"corporation":false,"usgs":true,"family":"Fairbrother","given":"A.","email":"","affiliations":[],"preferred":false,"id":409810,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Burdick, C.","contributorId":88918,"corporation":false,"usgs":true,"family":"Burdick","given":"C.","affiliations":[],"preferred":false,"id":409817,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Reichman, J.R.","contributorId":78130,"corporation":false,"usgs":true,"family":"Reichman","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":409816,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bollman, M.","contributorId":61219,"corporation":false,"usgs":true,"family":"Bollman","given":"M.","email":"","affiliations":[],"preferred":false,"id":409814,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Storm, M.","contributorId":31173,"corporation":false,"usgs":true,"family":"Storm","given":"M.","email":"","affiliations":[],"preferred":false,"id":409811,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"King, G.","contributorId":74521,"corporation":false,"usgs":true,"family":"King","given":"G.","email":"","affiliations":[],"preferred":false,"id":409815,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Van De Water, Peter K.","contributorId":51484,"corporation":false,"usgs":true,"family":"Van De Water","given":"Peter","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":409812,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Although the use of the impervious indicator is widespread, there is currently no consistent or mutually accepted method of computing impervious area and the approach of various commonly used techniques varies widely. Further, we do not have reliable information on the components of impervious surfaces, which would be critical in any future planning attempts to remediate problems associated with impervious surface coverage. In cooperation with the USGS Geographic Analysis and Monitoring Program (GAM) and The National Map, and the EPA Landscape Ecology Program, this collaborative research project utilized very high resolution imagery and GIS techniques to map and quantify the individual components of total impervious area in six urban/suburban watersheds in different parts of the United States. These data were served as ground reference, or \"truth,\" for the evaluation for four techniques used to compute impervious area. The results show some important aspects about the component make-up of impervious cover and the variability of methods commonly used to compile this critical emerging indicator of ecosystem

In this report, the performance characteristics of a combined solid-phase extraction isolation and high-performance liquid chromatography&ndash;electrospray ionization mass spectrometry (HPLC&ndash;ESI-MS) analytical procedure for routine determination of the presence and concentration of human-health pharmaceuticals are described. This method was developed and used in a recent national reconnaissance of pharmaceuticals in USA surface waters. The selection of pharmaceuticals evaluated for this method was based on usage estimates, resulting in a method that contains compounds from diverse chemical classes, which presents challenges and compromises when applied as a single routine analysis. The method performed well for the majority of the 22 pharmaceuticals evaluated, with recoveries greater than 60% for 12 pharmaceuticals. The recoveries of angiotensin-converting enzyme inhibitors, a histamine (H2) receptor antagonist, and antihypoglycemic compound classes were less than 50%, but were retained in the method to provide information describing the potential presence of these compounds in environmental samples and to indicate evidence of possible matrix enhancing effects. Long-term recoveries, evaluated from reagent-water fortifications processed over 2 years, were similar to initial method performance. Method detection limits averaged 0.022 &mu;g/L, sufficient for expected ambient concentrations. Compound-dependent matrix effects on HPLC/ESI-MS analysis, including enhancement and suppression of ionization, were observed as a 20&ndash;30% increase in measured concentrations for three compounds and greater than 50% increase for two compounds. Changing internal standard and more frequent ESI source maintenance minimized matrix effects. Application of the method in the national survey demonstrates that several pharmaceuticals are routinely detected at 0.010&ndash;0.100 &mu;g/L concentrations.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.chroma.2004.04.005","issn":"00219673","usgsCitation":"Cahill, J., Furlong, E., Burkhardt, M., Kolpin, D., and Anderson, L., 2004, Determination of pharmaceutical compounds in surface- and ground-water samples by solid-phase extraction and high-performance liquid chromatography-electrospray ionization mass spectrometry: Journal of Chromatography A, v. 1041, no. 1-2, p. 171-180, https://doi.org/10.1016/j.chroma.2004.04.005.","productDescription":"10 p.","startPage":"171","endPage":"180","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":351,"text":"Iowa Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":235326,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209119,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chroma.2004.04.005"}],"volume":"1041","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ffbce4b0c8380cd4f381","contributors":{"authors":[{"text":"Cahill, J.D.","contributorId":77342,"corporation":false,"usgs":true,"family":"Cahill","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":411991,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Furlong, E.

However, development of these equations for nongame fishes has only recently been emphasized. We used the regression-line-percentile technique to develop standard weight equations for four rare desert fishes: flannelmouth sucker Catostomus latipinnis, razorback sucker Xyrauchen texanus, roundtail chub Gila robusta, and humpback chub G. cypha. The Ws equation for flannelmouth suckers of 100-690 mm total length (TL) was developed from 17 populations: log10Ws = -5.180 + 3.068 log10TL. The Ws equation for razorback suckers of 110-885 mm TL was developed from 12 populations: log 10Ws = -4.886 + 2.985 log10TL.

Specifically, we characterize differences in transition metal (Fe, Mn, Mo, V, Ni, Zn, Pb and U) concentrations in black shales of the Hushpuckney Shale Member of the Swope Limestone in Iowa and equivalent black shale beds of the Coffeyville Formation in Oklahoma. Although C-S-Fe systematics and uniform 34S-depleted isotope ratios of pyrite indicate pervasive euxinic deposition (anoxic and sulfidic bottom waters) for these shales, regional variations can be inferred for the efficiency of Mo scavenging and for the rates of siliciclastic sedimentation as expressed in spatially varying Fe/Al ratios. Black shales in Iowa show Mo enrichment roughly five times greater than that observed in coeval euxinic shales in Oklahoma. By contrast, Fe/Al ratios in Oklahoma shales are as much as five times greater than the continental ratio of 0.5 observed in the over- and underlying oxic facies and in the coeval black shales in Iowa. Recent work in modern marine settings has shown that enrichments in Fe commonly result from scavenging in a euxinic water column during syngenetic pyrite formation. In contrast to Fe, the concentrations of other transition metals (Mo, V, Ni, Pb, Zn, U) are typically more enriched in the black shales in Iowa relative to Oklahoma. The transition metal trends in these Paleozoic shales are reasonably interpreted in terms of early fixation in organic-rich sediments due to euxinic water-column conditions. However, regional variations in (1) rates of siliciclastic input, (2) organic reservoirs, including relative inputs of terrestrial versus marine organic matter, and (3) additional inputs of metals to bottom waters from contemporaneous hydrothermal vents are additional key controls that lead to geographic variation in the extent of metal enrichments preserved in ancient organic-rich sediments.

To date, only differential extraction-based approaches have been able to determine the presence of covalently bound, reduced forms of TNT in field soils. Here, we employed thermal elution, pyrolysis, and gas chromatography/mass spectrometry (GC/MS) to distinguish between covalently bound and noncovalently bound reduced forms of TNT in soil. Model soil organic matter-based matrixes were used to develop an assay in which noncovalently bound (monomeric) aminodinitrotoluene (ADNT) and diaminonitrotoluene (DANT) were desorbed from the matrix and analyzed at a lower temperature than covalently bound forms of these same compounds. A thermal desorption technique, evolved gas analysis, was initially employed to differentiate between covalently bound and added 15N-labeled monomeric compounds. A refined thermal elution procedure, termed \"double-shot analysis\" (DSA), allowed a sample to be sequentially analyzed in two phases. In phase 1, all of an added 15N-labeled monomeric contaminant was eluted from the sample at relatively low temperature. In phase 2 during high-temperature pyrolysis, the remaining covalently bound contaminants were detected. DSA analysis of soil from the Louisiana Army Ammunition Plant (LAAP; ???5000 ppm TNT) revealed the presence of DANT, ADNT, and TNT. After scrutinizing the DSA data and comparing them to results from solvent-extracted and base/acid-hydrolyzed LAAP soil, we concluded that the TNT was a noncovalently bound \"carryover\" from phase 1. Thus, the pyrolysis-GC/MS technique successfully defined covalently bound pools of ADNT and DANT in the field soil sample.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es034911v","issn":"0013936X","usgsCitation":"Weiss, J., Mckay, A., Derito, C., Watanabe, C., Thorn, K.A., and Madsen, E., 2004, Development and Application of Pyrolysis Gas Chromatography/Mass Spectrometry for the Analysis of Bound Trinitrotoluene Residues in Soil: Environmental Science & Technology, v. 38, no. 7, p. 2167-2174, https://doi.org/10.1021/es034911v.","startPage":"2167","endPage":"2174","numberOfPages":"8","costCenters":[],"links":[{"id":235283,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209090,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es034911v"}],"volume":"38","issue":"7","noUsgsAuthors":false,"publicationDate":"2004-03-03","publicationStatus":"PW","scienceBaseUri":"505a0013e4b0c8380cd4f598","contributors":{"authors":[{"text":"Weiss, J.M.","contributorId":105499,"corporation":false,"usgs":true,"family":"Weiss","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":411671,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mckay, A.J.","contributorId":101062,"corporation":false,"usgs":true,"family":"Mckay","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":411669,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Derito, C.","contributorId":73796,"corporation":false,"usgs":true,"family":"Derito","given":"C.","email":"","affiliations":[],"preferred":false,"id":411668,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Watanabe, C.","contributorId":101427,"corporation":false,"usgs":true,"family":"Watanabe","given":"C.","email":"","affiliations":[],"preferred":false,"id":411670,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Thorn, K.

Much of the historic earthquake research done in the United States has focused on the New Madrid Seismic Zone (NMSZ), because the largest New Madrid earthquakes may represent the archetype for the most damaging earthquakes to be expected in intraplate regions. Published magnitude values ranging from 7.0 to 8.75 have generally been based on macroseismic effects, which provide the most direct constraint on source size for the events. Critical to the interpretation of these accounts is an understanding of their historic context. Early settlments clustered along waterways, where substantial amplification of seismic waves is expected. Analyzing the New Madrid intensity values with a consideration of these effects yields preferred values of Mw 7.2-7.3, 7.0, and 7.4-7.5 for the December, January, and February mainshocks, respectively, and of 7.0 for the «dawn\naftershock». These values are consistent with other lines of evidence, including scaling relationships. Finally, I show that accounts from the New Madrid sequence reveal evidence for remotely triggered earthquakes well outside the NMSZ. Remotely triggered earthquakes represent a potentially important new wrinkle in historic earthquake research, as their ground motions can sometimes be confused with mainshock ground motions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Annals of Geophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.4401/ag-3318","issn":"15935213","usgsCitation":"Hough, S., 2004, Scientific overview and historical context of the 1811-1812 new Madrid earthquake sequence: Annals of Geophysics, v. 47, no. 2-3, p. 523-537, https://doi.org/10.4401/ag-3318.","startPage":"523","endPage":"537","numberOfPages":"15","costCenters":[],"links":[{"id":487487,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4401/ag-3318","text":"Publisher Index Page"},{"id":269206,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.4401/ag-3318"},{"id":235251,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"47","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b878ae4b08c986b316539","contributors":{"authors":[{"text":"Hough, S.

We examine if static coseismic and transient postseismic deformation following the 1819 earthquake contributed to the enhanced seismicity in the region and the occurrence of the 2001 Bhuj earthquake, ???100 km away and almost two centuries later. Based on the Indian shield setting, great rupture depth of the 2001 event and lack of significant early postseismic deformation measured following the 2001 event, we infer that little viscous relaxation occurs in the lower crust and choose an upper mantle effective viscosity of 1019 Pas. The predicted Coulomb failure stress (DCFS) on the rupture plane of the 2001 event increased by more than 0.1 bar at 20 km depth, which is a small but possibly significant amount.

Lipid peroxidation (LPO) levels (lipid hydroperoxides) were measured in kidney, liver and brain samples taken at the beginning of the experiment (0-h unstressed controls) and at 6, 24 and 48 h after application of a continuous low-water stressor. Tissue samples were also taken at 48 h from fish that had not been exposed to the stressor (48-h unstressed controls). Exposure to the low-water stressor affected LPO in kidney and brain tissues. In kidney, LPO decreased 6 h after imposition of the stressor; similar but less pronounced decreases also occurred in the liver and brain. At 48 h, LPO increased (in comparison with 6-h stressed tissues) in the kidney and brain. In comparison with 48-h unstressed controls, LPO levels were higher in the kidney and brain of stressed fish. Although preliminary, results suggest that stress can cause oxidative tissue damage in juvenile chinook salmon. Measures of oxidative stress have shown similar responses to stress in mammals; however, further research is needed to determine the extent of the stress-oxidative stress relationship and the underlying physiological mechanisms in fish.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Aquaculture Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2109.2004.01080.x","issn":"1355557X","usgsCitation":"Welker, T., and Congleton, J., 2004, Oxidative stress in juvenile chinook salmon, Oncorhynchus tshawytscha (Walbaum): Aquaculture Research, v. 35, no. 9, p. 881-887, https://doi.org/10.1111/j.1365-2109.2004.01080.x.","startPage":"881","endPage":"887","numberOfPages":"7","costCenters":[],"links":[{"id":478329,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2109.2004.01080.x","text":"Publisher Index Page"},{"id":209115,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2109.2004.01080.x"},{"id":235320,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a726ee4b0c8380cd76ac2","contributors":{"authors":[{"text":"Welker, T.L.","contributorId":101063,"corporation":false,"usgs":true,"family":"Welker","given":"T.L.","affiliations":[],"preferred":false,"id":411685,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Congleton, J.L.","contributorId":65622,"corporation":false,"usgs":true,"family":"Congleton","given":"J.L.","affiliations":[],"preferred":false,"id":411684,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We present the first molecular phylogenetic analysis (using nuclear ITS sequences) that includes members of all sections of Orobanche, Gymnocaulis, Myzorrhiza, Trionychon, and Orobanche. Orobanche is not monophyletic, but falls into two lineages: (1) the Orobanche group comprises Orobanche sect. Orobanche and the small Near Asian genus Diphelypaea and is characterized by a chromosome base number of x = 19 and (2) the Phelipanche group contains Orobanche sects. Gymnocaulis, Myzorrhiza, and Trionychon and possesses a chromosome base number of x = 12. The relationships between these two groups and to other genera such as Boschniakia or Cistanche remain unresolved. Within the Orobanche group, Orobanche macrolepis and Orobanche anatolica (including Orobanche colorata) constitute two phylogenetically distinct lineages. Intrasectional structurings proposed by some authors for O. sect. Orobanche are not confirmed by the molecular data. In most cases, intraspecific sequence divergence between accessions, if present, is negligible and not correlated with morphological or ecological traits. In a few cases, however, there is evidence for the presence of cryptic taxa. ?? 2003 Elsevier Science (USA).

We used implanted radio transmitters to record the heart rates of geese as an observer experimentally approached them at a constant walking speed. On average, geese flushed when observers were 47 m (range: 25–100 m) away. Change point regression was used to identify the point in time when heart rate abruptly increased prior to flushing and when heart rate began to level off in flight after flushing. Heart rates of geese increased as the observer approached them during five of six disturbance trials, from 114.1 ± 6.6 beats/min during the observer's initial approach to 154.8 ± 7.4 beats/min just prior to flushing at the first change point. On average, goose heart rates began to increase most rapidly 5 sec prior to taking flight, and continued to increase rapidly for 4 sec after flushing until reaching flight speed. Heart rate was 456.2 ± 8.4 beats/min at the second change point, which occurred immediately after flushing, and 448.3 ± 9.5 beats/min 1 min later during flight.

Two earthquakes, including the 3 November 2002 M7.9 Denali fault earthquake, with epicenters approximately 275 km from the building, generated long trains of long-period (>1 s) surface waves. The other two smaller earthquakes occurred at subcrustal depths practically beneath Anchorage and produced higher frequency motions. These two pairs of earthquakes have different impacts on the response of the building. Higher modes are more pronounced in the building response during the smaller nearby events. The building responses indicate that the close-coupling of translational and torsional modes causes a significant beating effect. It is also possible that there is some resonance occurring due to the site frequency being close to the structural frequency.

One hypothesis for the population decline states that reproductive success has decreased because female scaup are arriving on breeding areas in poorer body condition than they did historically (i.e. spring condition hypothesis). We tested one aspect of that hypothesis by comparing body mass and nutrient reserves (lipid, protein, and mineral) of Lesser Scaup at four locations (Louisiana, Illinois, Minnesota, and Manitoba) between the 1980s and 2000s. We found that mean body mass and lipid and mineral reserves of females were 80.0, 52.5, and 3.0 g higher, respectively, in the 2000s than in the 1980s in Louisiana; similarly, body mass and lipid and mineral reserves of males were 108.8, 72.5, and 2.5 g higher, respectively. In Illinois, mean body mass and lipid reserves of females were 88.6 and 56.5 g higher, respectively, in the 2000s than in the 1980s; similarly, body mass and lipid and mineral reserves of males were 80.6, 76.0, and 2.7 g higher, respectively. Mean body mass of females were 58.5 and 58.9 g lower in the 2000s than in the 1980s in Minnesota and Manitoba, respectively; mean body mass of males, similarly, were 40.7 g lower in Minnesota. Mean lipid reserves of females in the 2000s were 28.8 and 27.8 g lower than those in the 1980s in Minnesota and Manitoba, respectively. Mean mineral reserves of females in the 2000s were 3.2 g lower than those in the 1980s in Manitoba. Consequently, females arriving to breed in Manitoba in the 2000s had accumulated lipid reserves for 4.1 fewer eggs and mineral reserves for 0.8 fewer eggs than those arriving to breed there in the 1980s. Accordingly, our results are consistent with the spring condition hypothesis and suggest that female body condition has declined, as reflected by decreases in body mass, lipids, and mineral reserves that could cause reductions in reproductive success and ultimately a population decline.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1642/0004-8038(2004)121[0917:NROLSA]2.0.CO;2","issn":"00048038","usgsCitation":"Anteau, M., and Afton, A., 2004, Nutrient reserves of Lesser Scaup (<i>Aythya affinis</i>) during spring migration in the Mississippi Flyway: A test of the spring condition hypothesis: The Auk, v. 121, no. 3, p. 917-929, https://doi.org/10.1642/0004-8038(2004)121[0917:NROLSA]2.0.CO;2.","productDescription":"13 p.","startPage":"917","endPage":"929","costCenters":[],"links":[{"id":478091,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/0004-8038(2004)121[0917:nrolsa]2.0.co;2","text":"Publisher Index Page"},{"id":235511,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"121","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6994e4b0c8380cd73dd7","contributors":{"authors":[{"text":"Anteau, M.J.","contributorId":12807,"corporation":false,"usgs":true,"family":"Anteau","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":411863,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Afton, A.

Although surface rupture was not documented at the time of the earthquake, recent geologic investigations have identified and mapped a rupture on the Laguna Salada fault that can be associated with high probability with the 1892 event (Mueller and Rockwell, 1995). The only intensity-based magnitude estimate for the earthquake, M 7.8, was made by Strand (1980) based on an interpretation of macroseismic effects and a comparison of isoseismal areas with those from instrumentally recorded earthquakes. In this study we reinterpret original accounts of the Laguna Salada earthquake. We assign modified Mercalli intensity (MMI) values in keeping with current practice, focusing on objective descriptions of damage rather than subjective human response and not assigning MMI values to effects that are now known to be poor indicators of shaking level, such as liquefaction and rockfalls. The reinterpreted isoseismal contours and the estimated magnitude are both significantly smaller than those obtained earlier. Using the method of Bakun and Wentworth (1997) we obtain a magnitude estimate of M 7.2 and an optimal epicenter less than 15 km from the center of the mapped Laguna Salada rupture. The isoseismal contours are elongated toward the northwest, which is qualitatively consistent with a directivity effect, assuming that the fault ruptured from southeast to northwest. We suggest that the elongation may also thus reflect wave propagation effects, with more efficient propagation of crustal surface (Lg) waves in the direction of the overall regional tectonic fabric.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/012003244","issn":"00371106","usgsCitation":"Hough, S., and Elliot, A., 2004, Revisiting the 23 February 1892 Laguna Salada earthquake: Bulletin of the Seismological Society of America, v. 94, no. 4, p. 1571-1578, https://doi.org/10.1785/012003244.","startPage":"1571","endPage":"1578","numberOfPages":"8","costCenters":[],"links":[{"id":478241,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://zenodo.org/record/1235799","text":"External Repository"},{"id":209264,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/012003244"},{"id":235547,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"4","noUsgsAuthors":false,"publicationDate":"2004-08-01","publicationStatus":"PW","scienceBaseUri":"505aad2be4b0c8380cd86e48","contributors":{"authors":[{"text":"Hough, S.

These measurements show that hydrate increases shear strength and p-wave velocity in natural and reconstituted samples. The proportion of this increase depends on (1) the amount and distribution of hydrate present, (2) differences, in sediment properties, and (3) differences in test conditions. Stress-strain curves from the Mallik samples suggest that natural gas hydrate does not cement sediment grains. However, stress-strain curves from the Ottawa sand (containing laboratory-formed gas hydrate) do imply cementation is present. Acoustically, rock physics modeling shows that gas hydrate does not cement grains of natural Mackenzie Delta sediment. Natural gas hydrates are best modeled as part of the sediment frame. This finding is in contrast with direct observations and results of Ottawa sand containing laboratory-formed hydrate, which was found to cement grains (Waite et al. 2004). It therefore appears that the microscopic distribution of gas hydrates in sediment, and hence the effect of gas hydrate on sediment physical properties, differs between natural deposits and laboratory-formed samples. This difference may possibly be caused by the location of water molecules that are available to form hydrate. Models that use laboratory-derived properties to predict behavior of natural gas hydrate must account for these differences.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Mineralogist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2138/am-2004-8-909","issn":"0003004X","usgsCitation":"Winters, W., Pecher, I., Waite, W., and Mason, D., 2004, Physical properties and rock physics models of sediment containing natural and laboratory-formed methane gas hydrate: American Mineralogist, v. 89, no. 8-9, p. 1221-1227, https://doi.org/10.2138/am-2004-8-909.","productDescription":"7 p.","startPage":"1221","endPage":"1227","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":235577,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"89","issue":"8-9","noUsgsAuthors":false,"publicationDate":"2004-08-01","publicationStatus":"PW","scienceBaseUri":"505a7ab9e4b0c8380cd79079","contributors":{"authors":[{"text":"Winters, W.J.","contributorId":49796,"corporation":false,"usgs":true,"family":"Winters","given":"W.J.","email":"","affiliations":[],"preferred":false,"id":411602,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pecher, I.A.","contributorId":14011,"corporation":false,"usgs":true,"family":"Pecher","given":"I.A.","email":"","affiliations":[],"preferred":false,"id":411600,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Waite, W.F.","contributorId":40329,"corporation":false,"usgs":true,"family":"Waite","given":"W.F.","email":"","affiliations":[],"preferred":false,"id":411601,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mason, D.H.","contributorId":93952,"corporation":false,"usgs":true,"family":"Mason","given":"D.H.","email":"","affiliations":[],"preferred":false,"id":411603,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
