The Vs measurements were made using high-resolution seismic refraction and reflection methods. We find a clear difference in the Vs profiles between sites located on the river floodplains and those located in the upland urban areas of St. Louis. Vs30 (average Vs to 30-m depth) values in floodplain areas range from 200 to 290 m/s (NEHRP category D) and contrast with sites on the upland areas of St. Louis, which have Vs30 values ranging from 410 to 785 m/s (NEHRP categories C and B). The lower Vs30 values and earthquake recordings in the floodplains suggest a greater potential for stronger and more prolonged ground shaking in an earthquake. Spectral analysis of a M3.6 earthquake recorded on the St. Louis-area ANSS seismograph network indicates stronger shaking and potentially damaging S-wave resonant frequencies at NEHRP category D sites compared to ground motions at a rock site located on the Saint Louis University campus. ?? 2007, Earthquake Engineering Research Institute.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earthquake Spectra","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1193/1.2753548","issn":"87552930","usgsCitation":"Williams, R.A., Odum, J.K., Stephenson, W.J., and Herrmann, R., 2007, Shallow P- and S-wave velocities and site resonances in the St. Louis region, Missouri-Illinois: Earthquake Spectra, v. 23, no. 3, p. 711-726, https://doi.org/10.1193/1.2753548.","startPage":"711","endPage":"726","numberOfPages":"16","costCenters":[],"links":[{"id":211391,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1193/1.2753548"},{"id":238673,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"3","noUsgsAuthors":false,"publicationDate":"2007-08-01","publicationStatus":"PW","scienceBaseUri":"505b8e18e4b08c986b31871e","contributors":{"authors":[{"text":"Williams, R.

We used the phytohemagglutinin (PHA) skin test to assess T-lymphocyte function and the sheep red blood cell (SRBC) hemagglutination test to measure antibody-mediated immunity. The PHA stimulation index among chicks receiving dietary Hg treatment did not differ significantly from those of chicks on the control diet (p = 0.15). Total antibody (immunoglobulin [Ig] M [primary antibody] + IgG [secondary response]) production to the SRBC antigen in chicks treated with dietary methylmercury (MeHg), however, was suppressed (p = 0.04) relative to chicks on control diets. Analysis indicated suppression of total Ig production (p = 0.025 with comparisonwise ?? level = 0.017) between control and 0.4 ??g Hg/g wet food intake treatment groups. Furthermore, the control group exhibited a higher degree of variability in antibody response compared to the Hg groups, suggesting that in addition to reducing the mean response, Hg treatment reduced the normal variation attributable to other biological factors. We observed bursal lymphoid depletion in chicks receiving the 1.2 ??g Hg/g treatment (p = 0.017) and a marginally significant effect (p = 0.025) in chicks receiving the 0.4 ??g Hg/g diet. These findings suggest that common loon chick immune systems may be compromised at an ecologically relevant dietary exposure concentration (0.4 ??g Hg/g wet wt food intake). We also found that chicks hatched from eggs collected from low-pH lakes exhibited higher levels of lymphoid depletion in bursa tissue relative to chicks hatched from eggs collected from neutral-pH lakes. ?? 2007 SETAC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/06-442R.1","issn":"07307268","usgsCitation":"Kenow, K., Grasman, K., Hines, R.K., Meyer, M., Gendron-Fitzpatrick, A., Spalding, M.G., and Gray, B., 2007, Effects of methylmercury exposure on the immune function of juvenile common loons (Gavia immer): Environmental Toxicology and Chemistry, v. 26, no. 7, p. 1460-1469, https://doi.org/10.1897/06-442R.1.","startPage":"1460","endPage":"1469","numberOfPages":"10","costCenters":[],"links":[{"id":211420,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/06-442R.1"},{"id":238705,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"7","noUsgsAuthors":false,"publicationDate":"2007-07-01","publicationStatus":"PW","scienceBaseUri":"505a075fe4b0c8380cd51674","contributors":{"authors":[{"text":"Kenow, K.P.","contributorId":18302,"corporation":false,"usgs":true,"family":"Kenow","given":"K.P.","affiliations":[],"preferred":false,"id":429429,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grasman, K.A.","contributorId":6249,"corporation":false,"usgs":true,"family":"Grasman","given":"K.A.","affiliations":[],"preferred":false,"id":429427,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hines, R.

However, these barriers can also isolate and protect native taxa from aggressive downstream invaders. We examined fish community composition two years prior to and two years after the removal of a pair of low-head dams from Boulder Creek, Wisconsin, U.S.A. in 2003 to determine if removal of these potential barriers affected the resident population of native brook trout (Salvelinus fontinalis). Despite the presence of other taxa in the downstream reaches, and in other similar streams adjacent to the Boulder Creek (including the brown trout, Salmo trutta), no new species had colonized the Boulder Creek in the two years following dam removal. The adults catch per unit effort (CPUE) was lower and the young-of-the-year catch per unit effort (YOY CPUE) was higher in 2005 than in 2001 in all reaches, but the magnitude of these changes was substantially larger in the two dam-affected sample reaches relative to an upstream reference reach, indicating a localized effect of the removal. Total length of the adults and the YOY and the adult body condition did not vary between years or among reaches. Thus, despite changes in numbers of adults and the YOYs in some sections of the stream, the lack of new fish species invading Boulder Creek and the limited extent of population change in brook trout indicate that dam removal had a minor effect on these native salmonids in the first two years of the post-removal.

Using 205 sediment samples and >1200 images from a variety of beaches on the west coast of the US, grain size ranging from sand to granules was measured from field samples using both the autocorrelation technique developed by Rubin [Rubin, D.M., 2004. A simple autocorrelation algorithm for determining grain size from digital images of sediment. Journal of Sedimentary Research, 74(1): 160-165.] and traditional methods (i.e. settling tube analysis, sieving, and point counts). To test the accuracy of the digital-image grain size algorithm, we compared results with manual point counts of an extensive image data set in the Santa Barbara littoral cell. Grain sizes calculated using the autocorrelation algorithm were highly correlated with the point counts of the same images (r2 = 0.93; n = 79) and had an error of only 1%. Comparisons of calculated grain sizes and grain sizes measured from grab samples demonstrated that the autocorrelation technique works well on high-energy dissipative beaches with well-sorted sediment such as in the Pacific Northwest (r2 ??? 0.92; n = 115). On less dissipative, more poorly sorted beaches such as Ocean Beach in San Francisco, results were not as good (r2 ??? 0.70; n = 67; within 3% accuracy). Because the algorithm works well compared with point counts of the same image, the poorer correlation with grab samples must be a result of actual spatial and vertical variability of sediment in the field; closer agreement between grain size in the images and grain size of grab samples can be achieved by increasing the sampling volume of the images (taking more images, distributed over a volume comparable to that of a grab sample). In all field tests the autocorrelation method was able to predict the mean and median grain size with ???96% accuracy, which is more than adequate for the majority of sedimentological applications, especially considering that the autocorrelation technique is estimated to be at least 100 times faster than traditional methods.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Sedimentary Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.sedgeo.2007.05.016","issn":"00370738","usgsCitation":"Barnard, P., Rubin, D.M., Harney, J., and Mustain, N., 2007, Field test comparison of an autocorrelation technique for determining grain size using a digital 'beachball' camera versus traditional methods: Sedimentary Geology, v. 201, no. 1-2, p. 180-195, https://doi.org/10.1016/j.sedgeo.2007.05.016.","startPage":"180","endPage":"195","numberOfPages":"16","costCenters":[],"links":[{"id":211617,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.sedgeo.2007.05.016"},{"id":238936,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"201","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0fdce4b0c8380cd53a47","contributors":{"authors":[{"text":"Barnard, P.L.","contributorId":20527,"corporation":false,"usgs":true,"family":"Barnard","given":"P.L.","email":"","affiliations":[],"preferred":false,"id":429489,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rubin, D.

This river flows through Woburn and Winchester (Massachusetts, USA), an area that is highly urbanized, has a long history of industrial activities dating to the early 1800s, and has gained national attention because of contamination from chlorinated solvent compounds in Woburn wells G and H. The river study section is in Winchester and begins approximately five stream kilometers downstream from the Woburn wells superfund site. Approximately 300 toxic release sites are documented in the watershed upstream from the terminus of the study section. The inflow to the river study section is considered one source of contamination. Other sources are the atmosphere, a tributary flow, and groundwater flows entering the river; the latter are categorized according to stream zone (1, 2, 3, etc.). Loss processes considered include outflows to groundwater and water-to-atmosphere transfer of volatile compounds. For both trichloroethylene and methyl-rerf-butyl ether, degradation is neglected over the timescale of interest. Source apportionment fractions with assigned values ??inflow, ??1, ??2, ??3, etc. are tracked by a source apportionment model. The strengths of the groundwater and tributary sources serve as fitting parameters when minimizing a reduced least squares statistic between water concentrations measured during a synoptic study in July 2001 versus predictions from the model. The model fits provide strong evidence of substantial unknown groundwater sources of trichloroethylene and methyl-tert-butyl ether amounting to tens of grams per day of trichloroethylene and methyl-tert-butyl ether in the river along the study section. Modeling in a source apportionment manner can be useful to water quality managers allocating limited resources for remediation and source control. ?? 2007 SETAC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/06-557R.1","issn":"07307268","usgsCitation":"Asher, W., Luo, W., Campo, K., Bender, D., Robinson, K.W., Zogorski, J., and Pankow, J.F., 2007, Application of a source apportionment model in consideration of volatile organic compounds in an urban stream: Environmental Toxicology and Chemistry, v. 26, no. 8, p. 1606-1613, https://doi.org/10.1897/06-557R.1.","startPage":"1606","endPage":"1613","numberOfPages":"8","costCenters":[],"links":[{"id":211641,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/06-557R.1"},{"id":238968,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"8","noUsgsAuthors":false,"publicationDate":"2007-08-01","publicationStatus":"PW","scienceBaseUri":"5059ec93e4b0c8380cd4935d","contributors":{"authors":[{"text":"Asher, W.E.","contributorId":99339,"corporation":false,"usgs":true,"family":"Asher","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":429498,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Luo, W.","contributorId":71331,"corporation":false,"usgs":true,"family":"Luo","given":"W.","email":"","affiliations":[],"preferred":false,"id":429497,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Campo, K.W.","contributorId":102270,"corporation":false,"usgs":true,"family":"Campo","given":"K.W.","email":"","affiliations":[],"preferred":false,"id":429499,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bender, D.A.","contributorId":49537,"corporation":false,"usgs":true,"family":"Bender","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":429496,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Robinson, K.

Crucian carp and SPMDs were deployed side by side for 32 d. The first-order uptake rate constants of individual PAHs and OCPs for the two matrices were calculated and compared to relate the amounts of chemicals accumulated by the matrices to dissolved water concentrations. On a wet-weight basis, total concentrations of PAHs and OCPs in crucian carp fillets averaged 49.5 and 13.6 ng/g, respectively, after the 32-d exposure, whereas concentrations in whole SPMDs averaged 716.9 and 62.3 ng/g, respectively. The uptake rate constants of PAHs and OCPs by SPMDs averaged seven- and fivefold higher, respectively, than those for crucian carp; however, the patterns of uptake rate constants derived from test chemical concentrations in the crucian carp and SPMDs were similar. Although equilibrium was not reached for some PAHs and OCPs during the 32-d exposure period, a reasonably good correlation between the concentration factors (CFs) and octanol/water partition coefficient (K ow) values of PAHs and OCPs in SPMDs (r = 0.86, p < 0.001) was observed when potential sorption to dissolved organic carbon was taken into account. Similar efforts to correlate the CFs and Kow values of PAHs and OCPs in crucian carp (r = 0.75, p < 0.001) were less successful, likely because of PAH metabolism by finfish. Overall, the present results suggest that SPMDs may serve as a surrogate for contaminant monitoring with fish in freshwater lake environments. ?? 2007 SETAC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/06-454R1.1","issn":"07307268","usgsCitation":"Ke, R., Xu, Y., Huang, S., Wang, Z., and Huckins, J., 2007, Comparison of the uptake of polycyclic aromatic hydrocarbons and organochlorine pesticides by semipermeable membrane devices and caged fish (Carassius carassius) in Taihu Lake, China: Environmental Toxicology and Chemistry, v. 26, no. 6, p. 1258-1264, https://doi.org/10.1897/06-454R1.1.","startPage":"1258","endPage":"1264","numberOfPages":"7","costCenters":[],"links":[{"id":211272,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/06-454R1.1"},{"id":238535,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"6","noUsgsAuthors":false,"publicationDate":"2007-06-01","publicationStatus":"PW","scienceBaseUri":"5059f8b1e4b0c8380cd4d227","contributors":{"authors":[{"text":"Ke, R.","contributorId":51090,"corporation":false,"usgs":true,"family":"Ke","given":"R.","email":"","affiliations":[],"preferred":false,"id":429533,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xu, Y.","contributorId":47816,"corporation":false,"usgs":true,"family":"Xu","given":"Y.","email":"","affiliations":[],"preferred":false,"id":429532,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Huang, S.","contributorId":18168,"corporation":false,"usgs":true,"family":"Huang","given":"S.","affiliations":[],"preferred":false,"id":429531,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wang, Z.","contributorId":67976,"corporation":false,"usgs":true,"family":"Wang","given":"Z.","affiliations":[],"preferred":false,"id":429535,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Huckins, J.N.","contributorId":62553,"corporation":false,"usgs":true,"family":"Huckins","given":"J.N.","email":"","affiliations":[],"preferred":false,"id":429534,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Similarly, among 89-day-1-year-old and 1+year old post-metamorphosed juveniles, cumulative mortality was significantly greater in VHSV-challenged groups than in respective control groups. Larval exposure to VHSV conferred partial protection to the survivors after their metamorphosis to juveniles as shown by significantly less cumulative mortalities among juvenile groups that survived a VHS epidemic as larvae than among groups that were previously nai??ve to VHSV. Magnitude of the protection, measured as relative per cent survival, was a direct function of larval age at first exposure and was probably a reflection of gradual developmental onset of immunocompetence.

Here we examine a potential explanation that we call the biogeographic affinity hypothesis, which proposes that the productivity-richness relationship is a function of species' climatic tolerances that in turn are shaped by the earth's climatic history combined with evolutionary niche conservatism. Using botanical data from regions and sites across California, we find support for a key prediction of this hypothesis, namely, that the productivity-species richness relationship differs strongly and predictably among groups of higher taxa on the basis of their biogeographic affinities (i.e., between families or genera primarily associated with north-temperate, semiarid, or desert zones). We also show that a consideration of biogeographic affinity can yield new insights on how productivity-richness patterns at large geographic scales filter down to affect patterns of species richness and composition within local communities. ?? 2007 by The University of Chicago.

Also, forest managers are engaging in fuel reduction projects to lessen fire severity, often without considering potential negative ecological consequences such as nonnative plant species introductions. Increased availability of light, nutrients, and bare ground have all been associated with high-severity fires and fuel treatments and are known to aid in the establishment of nonnative plant species. We use vegetation and environmental data collected after wildfires at seven sites in coniferous forests in the western United States to study responses of nonnative plants to wildfire. We compared burned vs. unburned plots and plots treated with mechanical thinning and/or prescribed burning vs. untreated plots for nonnative plant species richness and cover and used correlation analyses to infer the effect of abiotic site conditions on invasibility. Wildfire was responsible for significant increases in nonnative species richness and cover, and a significant decrease in native cover. Mechanical thinning and prescribed fire fuel treatments were associated with significant changes in plant species composition at some sites. Treatment effects across sites were minimal and inconclusive due to significant site and site x treatment interaction effects caused by variation between sites including differences in treatment and fire severities and initial conditions (e.g., nonnative species sources). We used canonical correspondence analysis (CCA) to determine what combinations of environmental variables best explained patterns of nonnative plant species richness and cover. Variables related to fire severity, soil nutrients, and elevation explained most of the variation in species composition. Nonnative species were generally associated with sites with higher fire severity, elevation, percentage of bare ground, and lower soil nutrient levels and lower canopy cover. Early assessments of postfire stand conditions can guide rapid responses to nonnative plant invasions. ?? 2007 by the Ecological Society of America.</p>","language":"English","publisher":"Ecological

We determined the nitrogen isotopic signatures (δ<sup>15</sup>N) of different nitrate sources to Hanalei Bay along with the isotopic signature recorded by 11 species of macroalgal collected in the Bay. The macroalgae integrate the isotopic signatures of the nitrate sources over time, thus these data along with the nitrate to dissolved inorganic phosphate molar ratios (N:P) of the macroalgae were used to determine the major nitrate source to the bay ecosystem and which of the macro-nutrients is limiting algae growth, respectively. Relatively low δ<sup>15</sup>N values (average −0.5‰) were observed in all algae collected throughout the Bay; implicating fertilizer, rather than domestic sewage, as an important external source of nitrogen to the coastal water around Hanalei. The N:P ratio in the algae compared to the ratio in the Bay waters imply that the Hanalei Bay coastal ecosystem is nitrogen limited and thus, increased nitrogen input may potentially impact this coastal ecosystem and specifically the coral reefs in the Bay. Identifying the major source of nutrient loading to the Bay is important for risk assessment and potential remediation plans.</p></div></div></div></div></div>","language":"English","publisher":"American Chemical Society","doi":"10.1021/es0700449","issn":"0013936X","usgsCitation":"Derse, E., Knee, K., Wankel, S.D., Kendall, C., Berg, C.J., and Paytan, A., 2007, Identifying sources of nitrogen to Hanalei Bay, Kauai, utilizing the nitrogen isotope signature of macroalgae: Environmental Science & Technology, v. 41, no. 15, p. 5217-5223, https://doi.org/10.1021/es0700449.","productDescription":"7 p.","startPage":"5217","endPage":"5223","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":238939,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kauai Island, Hanalei Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -159.53350067138672,\n              22.19916683397288\n            ],\n            [\n              -159.48526382446286,\n              22.19916683397288\n            ],\n            [\n              -159.48526382446286,\n              22.234446448737298\n            ],\n            [\n              -159.53350067138672,\n              22.234446448737298\n            ],\n            [\n              -159.53350067138672,\n              22.19916683397288\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"41","issue":"15","noUsgsAuthors":false,"publicationDate":"2007-06-19","publicationStatus":"PW","scienceBaseUri":"505a3856e4b0c8380cd6152b","contributors":{"authors":[{"text":"Derse, E.","contributorId":55637,"corporation":false,"usgs":true,"family":"Derse","given":"E.","email":"","affiliations":[],"preferred":false,"id":429648,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knee, K.L.","contributorId":13811,"corporation":false,"usgs":true,"family":"Knee","given":"K.L.","affiliations":[],"preferred":false,"id":429646,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wankel, Scott D.","contributorId":98076,"corporation":false,"usgs":true,"family":"Wankel","given":"Scott","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":429650,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kendall, Carol 0000-0002-0247-3405 ckendall@usgs.gov","orcid":"https://orcid.org/0000-0002-0247-3405","contributorId":1462,"corporation":false,"usgs":true,"family":"Kendall","given":"Carol","email":"ckendall@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":429647,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Berg, Carl J.

There is ample evidence that species distributions are determined by soils and habitat factors at landscape (<104 km2) and regional scales. At local scales (<1 km2), however, habitat factors and species distributions show comparable spatial aggregation, making it difficult to disentangle the importance of niche and dispersal processes. In this article, we test soil resource-based niche assembly at a local scale, using species and soil nutrient distributions obtained at high spatial resolution in three diverse neotropical forest plots in Colombia (La Planada), Ecuador (Yasuni), and Panama (Barro Colorado Island). Using spatial distribution maps of >0.5 million individual trees of 1,400 species and 10 essential plant nutrients, we used Monte Carlo simulations of species distributions to test plant-soil associations against null expectations based on dispersal assembly. We found that the spatial distributions of 36-51% of tree species at these sites show strong associations to soil nutrient distributions. Neutral dispersal assembly cannot account for these plant-soil associations or the observed niche breadths of these species. These results indicate that belowground resource availability plays an important role in the assembly of tropical tree communities at local scales and provide the basis for future investigations on the mechanisms of resource competition among tropical tree species. ?? 2007 by The National Academy of Sciences of the USA.","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.0604666104","issn":"00278424","usgsCitation":"John, R., Dalling, J., Harms, K., Yavitt, J., Stallard, R., Mirabello, M., Hubbell, S., Valencia, R., Navarrete, H., Vallejo, M., and Foster, R., 2007, Soil nutrients influence spatial distributions of tropical trees species: Proceedings of the National Academy of Sciences of the United States of America, v. 104, no. 3, p. 864-869, https://doi.org/10.1073/pnas.0604666104.","startPage":"864","endPage":"869","numberOfPages":"6","costCenters":[],"links":[{"id":477169,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/1783405","text":"External Repository"},{"id":214846,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1073/pnas.0604666104"},{"id":242598,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"104","issue":"3","noUsgsAuthors":false,"publicationDate":"2007-01-16","publicationStatus":"PW","scienceBaseUri":"505b9210e4b08c986b319c8e","contributors":{"authors":[{"text":"John, R.","contributorId":27689,"corporation":false,"usgs":true,"family":"John","given":"R.","email":"","affiliations":[],"preferred":false,"id":434034,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dalling, J.W.","contributorId":103103,"corporation":false,"usgs":true,"family":"Dalling","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":434042,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Harms, K.E.","contributorId":58856,"corporation":false,"usgs":true,"family":"Harms","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":434037,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Yavitt, J.B.","contributorId":96495,"corporation":false,"usgs":true,"family":"Yavitt","given":"J.B.","affiliations":[],"preferred":false,"id":434041,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stallard, R.F.","contributorId":30247,"corporation":false,"usgs":true,"family":"Stallard","given":"R.F.","email":"","affiliations":[],"preferred":false,"id":434035,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mirabello, M.","contributorId":91316,"corporation":false,"usgs":true,"family":"Mirabello","given":"M.","email":"","affiliations":[],"preferred":false,"id":434040,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hubbell, S.P.","contributorId":77376,"corporation":false,"usgs":true,"family":"Hubbell","given":"S.P.","email":"","affiliations":[],"preferred":false,"id":434039,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Valencia, R.","contributorId":64909,"corporation":false,"usgs":true,"family":"Valencia","given":"R.","email":"","affiliations":[],"preferred":false,"id":434038,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Navarrete, H.","contributorId":12704,"corporation":false,"usgs":true,"family":"Navarrete","given":"H.","email":"","affiliations":[],"preferred":false,"id":434032,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Vallejo, M.","contributorId":49622,"corporation":false,"usgs":true,"family":"Vallejo","given":"M.","email":"","affiliations":[],"preferred":false,"id":434036,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Foster, R.B.","contributorId":21360,"corporation":false,"usgs":true,"family":"Foster","given":"R.B.","email":"","affiliations":[],"preferred":false,"id":434033,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

Maps and reports of the region prepared by geologists commonly indicated that late Wisconsin ice extended as a large uniform front west to the edge of the continental shelf. However, the distribution of plants and animals in the region has led many biologists to suggest that there may have been ice-free areas that served as refugia during the late Wisconsin. Based on analyses of aerial photographs, topographic maps, and bathymetric charts, in conjunction with a review of previous literature and reconnaissance fieldwork throughout the region, this study presents data supporting a limited ice extent in the Alexander Archipelago during the late Wisconsin and identifies possible ice-free areas that may have served as refugia. These areas include (1) the Fairweather Ground, (2) the Herbert Graves Island area, (3) the western coast of southern Baranof Island and adjacent continental shelf, (4) Coronation Island and the adjacent continental shelf, (5) the Warren Island area, (6) the continental shelf from west of Heceta Island to Forrester Island in the south, (7) parts of the west coast of southern Dall Island, and (8) lowland areas in southern Prince of Wales Island. The identification of these possible refugia has bearing on the recolonization of the Alexander Archipelago, as they could have served as centers of biotic dispersal upon regional deglaciation and as stepping stones for early humans with a maritime tradition entering the western hemisphere from Asia. ?? 2007 NRC Canada.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Earth Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/E06-081","issn":"00084077","usgsCitation":"Carrara, P., Ager, T.A., and Baichtal, J., 2007, Possible refugia in the Alexander Archipelago of southeastern Alaska during the late Wisconsin glaciation: Canadian Journal of Earth Sciences, v. 44, no. 2, p. 229-244, https://doi.org/10.1139/E06-081.","startPage":"229","endPage":"244","numberOfPages":"16","costCenters":[],"links":[{"id":214845,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/E06-081"},{"id":242597,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7e36e4b0c8380cd7a3dc","contributors":{"authors":[{"text":"Carrara, P.

The acquired two-dimensional and three-dimensional data sets accurately image the channel bottom, demonstrating that the GPR tool can be used to estimate and/or monitor water depths in shallow fluvial environments. The study results demonstrate that the GPR tool is a safe and effective tool for measuring and/or monitoring scour in proximity to bridges. The technique can be used to safely monitor scour at assigned time intervals during peak flood stages, thereby enabling owners to take preventative action prior to potential failure. The GPR tool can also be used to investigate depositional and erosional patterns over time, thereby elucidating these processes on a local scale. In certain instances, in-filled scour features can also be imaged and mapped. This information may be critically important to those engaged in bridge design. GPR has advantages over other tools commonly employed for monitoring bridge scour (reflection seismic profiling, echo sounding, and electrical conductivity probing). The tool doesn't need to be coupled to the water, can be moved rapidly across (or above) the surface of a stream, and provides an accurate depth-structure model of the channel bottom and subchannel bottom sediments. The GPR profiles can be extended across emerged sand bars or onto the shore.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental and Engineering Geoscience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2113/gseegeosci.13.1.1","issn":"10787275","usgsCitation":"Anderson, N., Ismael, A., and Thitimakorn, T., 2007, Ground-penetrating radar: A tool for monitoring bridge scour: Environmental & Engineering Geoscience, v. 13, no. 1, p. 1-10, https://doi.org/10.2113/gseegeosci.13.1.1.","startPage":"1","endPage":"10","numberOfPages":"10","costCenters":[],"links":[{"id":214810,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2113/gseegeosci.13.1.1"},{"id":242562,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2b74e4b0c8380cd5b9c1","contributors":{"authors":[{"text":"Anderson, N.L.","contributorId":55129,"corporation":false,"usgs":true,"family":"Anderson","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":434022,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ismael, A.M.","contributorId":88168,"corporation":false,"usgs":true,"family":"Ismael","given":"A.M.","email":"","affiliations":[],"preferred":false,"id":434024,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thitimakorn, T.","contributorId":75770,"corporation":false,"usgs":true,"family":"Thitimakorn","given":"T.","email":"","affiliations":[],"preferred":false,"id":434023,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Because these variables can be measured remotely from topographic and river alignment information derived from aerial photos and satellite imagery, it is possible that the bankfull state of flow can be estimated for rivers entirely from remotely-sensed information. Defining the bankfull hydraulics of rivers would also provide a reference condition for remote tracking of dynamic variables including width, stage, and slope, and for quantifying relative change in flow conditions of rivers over large regions.

The target region comprises northern Norway and Finland, parts of the Kola Peninsula and the East European lowlands. Novaya Zemlya, the Kara Sea and Franz-Josef Land terminate the region to the east, while the Norwegian-Greenland Sea marks the western boundary. In total, 680 1-D seismic velocity profiles were compiled, mostly by sampling 2-D seismic velocity transects, from seismic refraction profiles. Seismic reflection data in the western Barents Sea were further used for density modelling and subsequent density-to-velocity conversion. Velocities from these profiles were binned into two sedimentary and three crystalline crustal layers. The first step of the compilation comprised the layer-wise interpolation of the velocities and thicknesses. Within the different geological provinces of the study region, linear relationships between the thickness of the sedimentary rocks and the thickness of the remaining crystalline crust are observed. We therefore, used the separately compiled (area-wide) sediment thickness data to adjust the total crystalline crustal thickness according to the total sedimentary thickness where no constraints from 1-D velocity profiles existed. The BARENTS50 model is based on an equidistant hexagonal grid with a node spacing of 50 km. The<span>&nbsp;</span><i>P</i>-wave velocity model was used for gravity modelling to obtain 3-D density structure. A better fit to the observed gravity was achieved using a grid search algorithm which focussed on the density contrast of the sediment-basement interface. An improvement compared to older geophysical models is the high resolution of 50 km. Velocity transects through the 3-D model illustrate geological features of the European Arctic. The possible petrology of the crystalline basement in western and eastern Barents Sea is discussed on the basis of the observed seismic velocity structure.

We monitored the cover of lichens and mosses, cyanobacterial biomass, concentrations of UV-protective pigments in both free-living and lichenized cyanobacteria, and quantum yield in the soil lichen species <i>Collema</i> in an undisturbed Mojave Desert shrubland. During our sampling time, the site received historically high and low levels of precipitation, whereas temperatures were close to normal. Lichen cover, dominated by <i>Collema tenax</i> and <i>C. coccophorum</i>, and moss cover, dominated by <i>Syntrichia caninervis</i>, responded to both increases and decreases in precipitation. This finding for <i>Collema</i> spp. at a hot Mojave Desert site is in contrast to a similar study conducted at a cool desert site on the Colorado Plateau in SE Utah, USA, where <i>Collema</i> spp. cover dropped in response to elevated temperatures, but did not respond to changes in rainfall. The concentrations of UV-protective pigments in free-living cyanobacteria at the Mojave Desert site were also strongly and positively related to rainfall received between sampling times (<i>R</i><sup>2</sup> values ranged from 0.78 to 0.99). However, pigment levels in the lichenized cyanobacteria showed little correlation with rainfall. Quantum yield in <i>Collema</i> spp. was closely correlated with rainfall. Climate models in this region predict a 3.5–4.0&nbsp;°C rise in temperature and a 15–20% decline in winter precipitation by 2099. Based on our data, this rise in temperature is unlikely to have a strong effect on the dominant species of the soil crusts. However, the predicted drop in precipitation will likely lead to a decrease in soil lichen and moss cover, and high stress or mortality in soil cyanobacteria as levels of UV-protective pigments decline. In addition, surface-disturbing activities (e.g., recreation, military activities, fire) are rapidly increasing in the Mojave Desert, and these disturbances quickly remove soil lichens and mosses. These stresses combined are likely to lead to shifts in species composition and the local extirpation of some lichen or moss species. As these organisms are critical components of nutrient cycling, soil fertility, and soil stability, such changes are likely to reverberate throughout these ecosystems.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.flora.2007.05.007","usgsCitation":"Belnap, J., Phillips, S.L., and Smith, S., 2007, Dynamics of cover, UV-protective pigments, and quantum yield in biological soil crust communities of an undisturbed Mojave Desert shrubland: Flora, v. 202, no. 8, p. 674-686, https://doi.org/10.1016/j.flora.2007.05.007.","productDescription":"13 p.","startPage":"674","endPage":"686","costCenters":[],"links":[{"id":239019,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Mojave Desert","volume":"202","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0432e4b0c8380cd50845","contributors":{"authors":[{"text":"Belnap, Jayne 0000-0001-7471-2279 jayne_belnap@usgs.gov","orcid":"https://orcid.org/0000-0001-7471-2279","contributorId":1332,"corporation":false,"usgs":true,"family":"Belnap","given":"Jayne","email":"jayne_belnap@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":430578,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Phillips, Susan L. 0000-0002-5891-8485 sue_phillips@usgs.gov","orcid":"https://orcid.org/0000-0002-5891-8485","contributorId":717,"corporation":false,"usgs":true,"family":"Phillips","given":"Susan","email":"sue_phillips@usgs.gov","middleInitial":"L.","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":false,"id":430580,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Smith, Stanley D.","contributorId":83417,"corporation":false,"usgs":true,"family":"Smith","given":"Stanley D.","affiliations":[],"preferred":false,"id":430579,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The National Wildlife Refuge Improvement Act of 1997 (Public Law 105-57, USC668dd) mandates a Comprehensive Conservation Plan (CCP) for every refuge in the system. A refuge CCP outlines goals, objectives, and management strategies for all refuge programs over the next 15 years, while providing opportunities for compatible, wildlifedependent public uses.

In addition, public review and comment on alternatives for future management is required.

For the uptake study, catfish were exposed to 100 mg/L sodium perchlorate for 12 h to 5 d in the laboratory. Perchlorate in tissues was analyzed using ion chromatography. The highest perchlorate concentrations were found in the head and fillet, indicating that these tissues are the most important tissues to analyze when determining perchlorate uptake into large fish. To calculate uptake and elimination rate constants for fillet, gills, G-I tract, liver, and head, fish were exposed to 100 ppm sodium perchlorate for 5 days, and allowed to depurate in clean water for up to 20 days. The animals rapidly eliminated the perchlorate accumulated showing the highest elimination in fillet (Ke = 1.67 day -1) and lowest elimination in liver (Ke = 0.79 day -1). ?? 2007 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es071365n","issn":"0013936X","usgsCitation":"Park, J.W., Bradford, C., Rinchard, J., Liu, F., Wages, M., Waters, A., Kendall, R., Anderson, T., and Theodorakis, C., 2007, Uptake, elimination, and relative distribution of perchlorate in various tissues of channel catfish: Environmental Science & Technology, v. 41, no. 21, p. 7581-7586, https://doi.org/10.1021/es071365n.","startPage":"7581","endPage":"7586","numberOfPages":"6","costCenters":[],"links":[{"id":211710,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es071365n"},{"id":239052,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"21","noUsgsAuthors":false,"publicationDate":"2007-09-22","publicationStatus":"PW","scienceBaseUri":"505bbd7be4b08c986b329052","contributors":{"authors":[{"text":"Park, J.

Lake trout %DMs were lower at greater temperatures, but not significantly different from 60??C controls. Rainbow smelt and slimy sculpin %DMs were lower at greater temperatures and differences were significant when test temperatures reached 90??C. Significant differences were not found in tests using alewives because variability in %DM was high between fish. To avoid inter-fish variability, 30 alewives were each dried successively at 60, 70, 80, and then 90??C and for all fish %DM declined at each higher temperature. In general, %DMs were lower at greater temperatures and after reaching a stable dry weight, fish did not lose additional mass if temperature remained constant. Results indicate that caution should be used when comparing dry mass related indices from fish dried at different temperatures because %DM was negatively related to temperature. The differences in %DM observed with rising temperature could account for substantial portions of the variability in reported energy values for the species tested.
