Two‐dimensional solute transport simulations with either zero‐order or first‐order degradation in the anaerobic zone corroborate this interpretation. The transport model was previously calibrated against detailed tritium profiles in the same wells. First‐order degradation is found to best match the observed CFC profiles yielding an approximate half‐life of a few months for CFC‐11. Degradation is not as clearly recognized for CFC‐12 and CFC‐113, but it may occur with rates corresponding to a half‐life of a few years or more. Data indicate a geochemical control of the CFC concentration gradient at the redox front and that denitrification and denitrifiers are not of major importance for the observed CFC degradation. The responsible mechanism behind the observed degradation is not known but we suggest that reductive dehalogenation by surface‐bound Fe(II) on pyrite possibly enhanced by the presence of Fe(III)‐bearing weathering products (green rust) may be a plausible mechanism. The observed data and the performed simulations confirm the potential application of the CFC gases as age‐dating tools in the aerobic part of the investigated aquifer, but also that CFC data must be analyzed carefully before it is used as a dating tool in reducing aquifers because degradation may have occurred. The use of multiple or alternative tracers should be considered in anaerobic environments.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2006WR005854","usgsCitation":"Hinsby, K., Højberg, A., Engesgaard, P., Jensen, K., Larsen, F., Plummer, N., and Busenberg, E., 2007, Transport and degradation of chlorofluorocarbons (CFCs) in the pyritic Rabis Creek aquifer, Denmark: Water Resources Research, v. 43, no. 10, Article W10423; 15 p., https://doi.org/10.1029/2006WR005854.","productDescription":"Article W10423; 15 p.","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":487015,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2006wr005854","text":"Publisher Index Page"},{"id":239857,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Denmark","otherGeospatial":"Rabis Creek aquifer","volume":"43","issue":"10","noUsgsAuthors":false,"publicationDate":"2007-10-20","publicationStatus":"PW","scienceBaseUri":"505bb73ae4b08c986b32711e","contributors":{"authors":[{"text":"Hinsby, K.","contributorId":15013,"corporation":false,"usgs":true,"family":"Hinsby","given":"K.","affiliations":[],"preferred":false,"id":431520,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Højberg, Anker L.","contributorId":187776,"corporation":false,"usgs":false,"family":"Højberg","given":"Anker L.","affiliations":[],"preferred":false,"id":431518,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Engesgaard, P.","contributorId":12695,"corporation":false,"usgs":true,"family":"Engesgaard","given":"P.","affiliations":[],"preferred":false,"id":431519,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jensen, K.H.","contributorId":75710,"corporation":false,"usgs":true,"family":"Jensen","given":"K.H.","email":"","affiliations":[],"preferred":false,"id":431522,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Larsen, F.","contributorId":104288,"corporation":false,"usgs":true,"family":"Larsen","given":"F.","affiliations":[],"preferred":false,"id":431524,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Plummer, Niel 0000-0002-4020-1013 nplummer@usgs.gov","orcid":"https://orcid.org/0000-0002-4020-1013","contributorId":190100,"corporation":false,"usgs":true,"family":"Plummer","given":"Niel","email":"nplummer@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":431523,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Busenberg, Eurybiades ebusenbe@usgs.gov","contributorId":2271,"corporation":false,"usgs":true,"family":"Busenberg","given":"Eurybiades","email":"ebusenbe@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":431521,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Little is known about the distribution of genetic variation across the species' range despite increasing pressure to make difficult management decisions regarding the two populations and flocks within them. To address this issue, we used rapidly evolving genetic markers (mitochondrial DNA sequence and 17 nuclear microsatellite loci) to elucidate the underlying genetic structure of the species. Data from both markers revealed a significant difference between the PP and RMP with the Yukon Territory as a likely area of overlap. Additionally, we found that the two populations have somewhat similar levels of genetic diversity (PP is slightly higher) suggesting that the PP underwent a population bottleneck similar to a well-documented one in the RMP. Both genetic structure and diversity results reveal that the Tri-State flock, a suspected unique, non-migratory flock, is not genetically different from the Canadian flock of the RMP and need not be treated as a unique population from a genetic standpoint. Finally, trumpeter swans appear to have much lower mitochondrial DNA variability than other waterfowl studied thus far which may suggest a previous, species-wide bottleneck. ?? 2007 Springer Science+Business Media, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Conservation Genetics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10592-006-9282-y","issn":"15660621","usgsCitation":"Oyler-McCance, S., Ransler, F., Berkman, L., and Quinn, T., 2007, A rangewide population genetic study of trumpeter swans: Conservation Genetics, v. 8, no. 6, p. 1339-1353, https://doi.org/10.1007/s10592-006-9282-y.","startPage":"1339","endPage":"1353","numberOfPages":"15","costCenters":[],"links":[{"id":212469,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10592-006-9282-y"},{"id":239959,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"6","noUsgsAuthors":false,"publicationDate":"2007-02-09","publicationStatus":"PW","scienceBaseUri":"5059e52ae4b0c8380cd46b92","contributors":{"authors":[{"text":"Oyler-McCance, S.J.","contributorId":75877,"corporation":false,"usgs":true,"family":"Oyler-McCance","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":431551,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ransler, F.A.","contributorId":92034,"corporation":false,"usgs":true,"family":"Ransler","given":"F.A.","email":"","affiliations":[],"preferred":false,"id":431552,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Berkman, L.K.","contributorId":9862,"corporation":false,"usgs":true,"family":"Berkman","given":"L.K.","email":"","affiliations":[],"preferred":false,"id":431549,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Quinn, T.W.","contributorId":37285,"corporation":false,"usgs":true,"family":"Quinn","given":"T.W.","email":"","affiliations":[],"preferred":false,"id":431550,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The metal loading to the stream was quantified by defining detailed profiles of discharge and concentration, using tracer-dilution and synoptic-sampling techniques. During the course of a field experiment to evaluate metal loading to the Merse, such data were obtained for both storm and pre-storm conditions, providing a unique opportunity for comparison. Iron, Cu, and Mn were chosen to illustrate changes resulting from the storm. The total-recoverable load of Fe increased 21-fold, while loads of Cu and Mn increased by 8- and 7-fold, respectively, during the storm runoff. The increases most likely resulted from flushing particulates from near the stream, resuspension of colloidal material from the streambed, and increased ground-water inflow to the stream. The increases in Cu and Mn loads results from their association with colloids. It is possible that in-stream colloids had relatively more Cu than Mn, while near-stream colloids had relatively more Mn. Each of the metals also increased as a result of increased ground-water discharge during the storm. Despite great increases in load, the filterable concentrations of these metals did not increase substantially, remaining below chronic levels of toxicity.</p>","language":"English","publisher":"Springer","doi":"10.1007/s10230-007-0020-6","issn":"10259112","usgsCitation":"Kimball, B.A., Bianchi, F., Walton-Day, K., Runkel, R.L., Nannucci, M.,

Flood forecasting can reduce the death toll associated with floods. Satellites offer effective and economical means for calculating areal rainfall estimates in sparsely gauged regions. However, satellite-based rainfall estimates have had limited use in flood forecasting and hydrologic stream flow modeling because the rainfall estimates were considered to be unreliable. In this study we present the calibration and validation results from a spatially distributed hydrologic model driven by daily satellite-based estimates of rainfall for sub-basins of the Nile and Mekong Rivers. The results demonstrate the usefulness of remotely sensed precipitation data for hydrologic modeling when the hydrologic model is calibrated with such data. However, the remotely sensed rainfall estimates cannot be used confidently with hydrologic models that are calibrated with rain gauge measured rainfall, unless the model is recalibrated. ??

Random forests (RF) is a new and powerful statistical classifier that is well established in other disciplines but is relatively unknown in ecology. Advantages of RF compared to other statistical classifiers include (1) very high classification accuracy; (2) a novel method of determining variable importance; (3) ability to model complex interactions among predictor variables; (4) flexibility to perform several types of statistical data analysis, including regression, classification, survival analysis, and unsupervised learning; and (5) an algorithm for imputing missing values. We compared the accuracies of RF and four other commonly used statistical classifiers using data on invasive plant species presence in Lava Beds National Monument, California, USA, rare lichen species presence in the Pacific Northwest, USA, and nest sites for cavity nesting birds in the Uinta Mountains, Utah, USA. We observed high classification accuracy in all applications as measured by cross-validation and, in the case of the lichen data, by independent test data, when comparing RF to other common classification methods. We also observed that the variables that RF identified as most important for classifying invasive plant species coincided with expectations based on the literature. ?? 2007 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/07-0539.1","issn":"00129658","usgsCitation":"Cutler, D., Edwards, T., Beard, K., Cutler, A., Hess, K., Gibson, J., and Lawler, J., 2007, Random forests for classification in ecology: Ecology, v. 88, no. 11, p. 2783-2792, https://doi.org/10.1890/07-0539.1.","startPage":"2783","endPage":"2792","numberOfPages":"10","costCenters":[],"links":[{"id":212176,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/07-0539.1"},{"id":239626,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"88","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9494e4b0c8380cd814c4","contributors":{"authors":[{"text":"Cutler, D.R.","contributorId":89684,"corporation":false,"usgs":true,"family":"Cutler","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":431629,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Edwards, T.C.

In recent years, the probability of detecting defined population trends has been the most common method of assessing monitoring programs. Such analyses require many assumptions, including a model for population change and a model for variance. To demonstrate potential effects of these assumptions on power analysis results, we present data for Red-tailed Tropicbirds (Phaethon rubricauda) from Tern Island, Hawaii. Depending on our assumptions, the power to detect a 50% decline over 10 years varied from 80% to 100%. We argue that monitoring standards based upon the ability to detect population trends should be applied cautiously. As a complementary approach, we propose that monitoring standards should emphasize attributes of sampling design that increase precision (e.g., randomization, bias, and detection probability). By using standards of precision, managers can focus on the sources of variation that can be minimized. A sampling design approach to monitoring standards provides a useful complement to standards of statistical power to detect annual trends.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2007.08.007","issn":"00063207","usgsCitation":"Seavy, N., and Reynolds, M., 2007, Is statistical power to detect trends a good assessment of population monitoring?: Biological Conservation, v. 140, no. 1-2, p. 187-191, https://doi.org/10.1016/j.biocon.2007.08.007.","startPage":"187","endPage":"191","numberOfPages":"5","costCenters":[],"links":[{"id":212472,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2007.08.007"},{"id":239962,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"140","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3f2ce4b0c8380cd64306","contributors":{"authors":[{"text":"Seavy, N.E.","contributorId":26403,"corporation":false,"usgs":true,"family":"Seavy","given":"N.E.","affiliations":[],"preferred":false,"id":431747,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, M.H. 0000-0001-7253-8158","orcid":"https://orcid.org/0000-0001-7253-8158","contributorId":64214,"corporation":false,"usgs":true,"family":"Reynolds","given":"M.H.","affiliations":[],"preferred":false,"id":431748,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We use trench mapping and radiometric dating to estimate displacements and timing of the last three surface-rupturing earthquakes (E1-E3) on the southern part of the fault south of Denio, Nevada. Coseismic displacements range from 1.1 to 2.2 ?? 0.5 m, and radiometric ages indicate earthquake times of 11.5 ?? 2.0 ka (E3), 6.1 ?? 0.5 ka (E2), and 4.6 ?? 1.0 ka (E1). These data yield recurrence intervals of 5.4 ?? 2.1 k.y. between E3 and E2, 1.5 ?? 1.1 k.y. between E2 and E1, and an elapsed time of 4.6 ?? 1.0 k.y. since E1. The recurrence data yield variable interval slip rates (between 0.2 ?? 0.22 and 1.5 ?? 2.3 mm/yr), but slip rates averaged over the past ???18 k.y. (0.24 ?? 0.06 mm/year) are similar to long-term (8.5-12.5 Ma) slip rates (0.2 ?? 0.1 mm /yr) measured a few kilometers to the north. We infer from the lack of significant topographic relief across the fault in Bog Hot Valley that the fault zone is propagating southward and may now be connected with a fault at the northwestern end of the Pine Forest Range. Displacements documented in the trench and a rupture length of 37 km indicate a history of three latest Quaternary earthquakes with magnitudes of M 6.6-7.1 on the southern part of the Steens fault zone.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120060202","issn":"00371106","usgsCitation":"Personius, S., Crone, A.J., Machette, M.N., Mahan, S., Kyung, J., Cisneros, H., and Lidke, D., 2007, Late quaternary paleoseismology of the southern Steens fault zone, northern Nevada: Bulletin of the Seismological Society of America, v. 97, no. 5, p. 1662-1678, https://doi.org/10.1785/0120060202.","startPage":"1662","endPage":"1678","numberOfPages":"17","costCenters":[],"links":[{"id":212178,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120060202"},{"id":239628,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"97","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4557e4b0c8380cd67229","contributors":{"authors":[{"text":"Personius, S.

In order to better understand the regional trends of change along the California coast, the U.S. Geological Survey is quantifying both sandy shoreline change and coastal cliff retreat for the state. The resulting database was used to examine the dynamics of the beach/cliff system. We found inconsistent evidence of a relationship between rates of cliff retreat and shoreline change on the spatial scale of 100-km cells. However, when the data are correlated within individual regions, a strong relationship exists between the geomorphology of the coast and the behavior of the beach/cliff system. Areas of high-relief coast show negative correlations, indicating that higher rates of cliff retreat correlate with lower rates of shoreline erosion. In contrast, low- to moderate-relief coasts show strong positive correlations.","largerWorkTitle":"Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceTitle":"6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceDate":"13 May 2007 through 17 May 2007","conferenceLocation":"New Orleans, LA","language":"English","doi":"10.1061/40926(239)133","isbn":"0784409269; 9780784409268","usgsCitation":"Hapke, C., and Reid, D., 2007, Regional beach/cliff system dynamics along the california coast, <i>in</i> Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, New Orleans, LA, 13 May 2007 through 17 May 2007, https://doi.org/10.1061/40926(239)133.","costCenters":[],"links":[{"id":212237,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/40926(239)133"},{"id":239695,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"50e4a4aee4b0e8fec6cdbbfc","contributors":{"authors":[{"text":"Hapke, C.J.","contributorId":108233,"corporation":false,"usgs":true,"family":"Hapke","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":431844,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reid, Don","contributorId":68110,"corporation":false,"usgs":true,"family":"Reid","given":"Don","affiliations":[],"preferred":false,"id":431843,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Because of the importance of hydrologic processes in stream ecosystems, a conceptual model known as nutrient spiraling is frequently employed. A central part of the nutrient spiraling approach is the determination of uptake length (</span><i>S</i><sub><i>w</i></sub><span>), the average distance traveled by dissolved nutrients in the water column before uptake. Although the nutrient spiraling concept has been an invaluable tool in stream ecology, the current practice of estimating uptake length from steady‐state nutrient data using linear regression (called here the “</span><i>S</i><sub><i>w</i></sub><span>&nbsp;approach”) presents a number of limitations. These limitations are identified by comparing the exponential&nbsp;</span><i>S</i><sub><i>w</i></sub><span>&nbsp;equation with analytical solutions of a stream solute transport model. This comparison indicates that (1)&nbsp;</span><i>S</i><sub><i>w</i></sub><span>&nbsp;is an aggregate measure of uptake that does not distinguish between main channel and storage zone processes, (2)&nbsp;</span><i>S</i><sub><i>w</i></sub><span>&nbsp;is an integrated measure of numerous hydrologic and nonhydrologic processes—this process integration may lead to difficulties in interpretation when comparing estimates of&nbsp;</span><i>S</i><sub><i>w</i></sub><span>, and (3) estimates of uptake velocity and areal uptake rate (</span><i>v</i><sub><i>f</i></sub><span>&nbsp;and&nbsp;</span><i>U</i><span>) based on&nbsp;</span><i>S</i><sub><i>w</i></sub><span>&nbsp;are not independent of system hydrology. Given these findings, a transport‐based approach to nutrient spiraling is presented for steady‐state and time‐series data sets. The transport‐based approach for time‐series data sets is suggested for future research on nutrient uptake as it provides a number of benefits, including the ability to (1) separately quantify main channel and storage zone uptake, (2) quantify specific hydrologic and nonhydrologic processes using various model parameters (process separation), (3) estimate uptake velocities and areal uptake rates that are independent of hydrologic effects, and (4) use shortterm, non‐plateau nutrient additions such that the effects of regeneration and mineralization are minimized. In summary, the transport‐based, time‐series approach provides a means of estimating traditional measures of nutrient uptake (</span><i>S</i><sub><i>w</i></sub><span>,&nbsp;</span><i>v</i><sub><i>f</i></sub><span>&nbsp;,&nbsp;</span><i>U</i><span>) while providing additional information on the location and magnitude of uptake (main channel versus storage zone). Application of the transport‐based approach to time‐series data from Green Creek, Antarctica, indicates that the bulk of nitrate uptake (~74% to 100%) occurred within the main channel where benthic uptake by algal mats is a likely process. Substantial uptake (~26%) also occurred in the storage zone of one reach, where uptake is attributed to the microbial community.</span></p>","language":"English","publisher":"ASLO","doi":"10.4319/lom.2007.5.50","usgsCitation":"Runkel, R.L., 2007, Toward a transport-based analysis of nutrient spiraling and uptake in streams: Limnology and Oceanography: Methods, v. 5, no. 1, p. 50-62, https://doi.org/10.4319/lom.2007.5.50.","productDescription":"13 p.","startPage":"50","endPage":"62","numberOfPages":"13","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":240083,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"5","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-01-22","publicationStatus":"PW","scienceBaseUri":"505bb5b2e4b08c986b326834","contributors":{"authors":[{"text":"Runkel, Robert L. 0000-0003-3220-481X runkel@usgs.gov","orcid":"https://orcid.org/0000-0003-3220-481X","contributorId":685,"corporation":false,"usgs":true,"family":"Runkel","given":"Robert","email":"runkel@usgs.gov","middleInitial":"L.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":432902,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Today, as was probably the case historically, the siscowet morphotype is the most abundant. Recent interest in harvesting siscowets to extract oil containing omega-3 fatty acids will require additional knowledge of the biology and stock structure of these lightly exploited populations. The objective of this study was to determine whether shape differences exist among siscowet populations across Lake Superior and whether these shape differences can be used to infer stock structure. Morphometric analysis (truss protocol) was used to differentiate among siscowets sampled from 23 locations in Lake Superior. We analyzed 31 distance measurements among 14 anatomical landmarks taken from digital images of fish recorded in the field. Cluster analysis of size-corrected data separated fish into three geographic groups: The Isle Royale, eastern (Michigan), and western regions (Michigan).

Determining the temporal and spatial patterns of migration and degree of population segregation during migration is critical to understanding long-term population trends of migrant birds. At all five migration sites, we found a significant negative relationship between the date Wilson’s Warblers passed through the sampling station and δD values of their feathers. These data were consistent with a pattern of “leap-frog” migration, in which individuals that bred the previous season at southern latitudes migrated through migration stations earlier than individuals that had previously bred at more northern latitudes. We documented that this pattern was consistent across sites and in multiple years. This finding corroborates previous research conducted on Wilson’s Warbler during the fall migration. In addition, mean δD values became more negative across sampling stations from west to east, with the mean δD values at each station corresponding to different geographic regions of the Wilson’s Warblers’ western breeding range. These data indicate that Wilson’s Warblers passing through each station represented a specific regional subset of the entire Wilson’s Warbler western breeding range. As a result, habitat alterations at specific areas across the east-west expanse of the bird’s migratory route in the southwestern United States could differentially affect Wilson’s Warblers at different breeding areas. This migration information is critical for management of Neotropical migrants, especially in light of the rapid changes presently occurring over the southwestern landscape.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1642/0004-8038(2007)124[162:SATMPO]2.0.CO;2","issn":"00048038","usgsCitation":"Paxton, K., van Riper, C., Theimer, T., and Paxton, E.H., 2007, Spatial and temporal migration patterns of Wilson's Warbler (<i>Wilsonia pusilla</i>) in the southwest as revealed by stable isotopes: The Auk, v. 124, no. 1, p. 162-175, https://doi.org/10.1642/0004-8038(2007)124[162:SATMPO]2.0.CO;2.","productDescription":"14 p.","startPage":"162","endPage":"175","costCenters":[],"links":[{"id":477143,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/0004-8038(2007)124[162:satmpo]2.0.co;2","text":"Publisher Index Page"},{"id":239775,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"124","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b943ce4b08c986b31a95a","contributors":{"authors":[{"text":"Paxton, K.L.","contributorId":78547,"corporation":false,"usgs":true,"family":"Paxton","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":432947,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"van Riper, Charles III 0000-0003-1084-5843 charles_van_riper@usgs.gov","orcid":"https://orcid.org/0000-0003-1084-5843","contributorId":169488,"corporation":false,"usgs":true,"family":"van Riper","given":"Charles","suffix":"III","email":"charles_van_riper@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":false,"id":432946,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Theimer, T.C.","contributorId":31580,"corporation":false,"usgs":true,"family":"Theimer","given":"T.C.","affiliations":[],"preferred":false,"id":432945,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Paxton, E.

Less than 25% of the pre-Columbian bottomland hardwood forests remain in the southeastern United States. Because of the valuable ecological and hydrological functions performed by these forests, their conservation and restoration has been a high priority. Part of these restoration efforts has focused on developing tools that can be used for both assessments at the landscape level and policy implementation at the local level. The distribution of bottomland hardwood forests in the Cache and White River watersheds in eastern Arkansas were examined using existing GIS databases. Criteria were developed to select areas that should be conserved or augmented for wildlife habitat. Over 67% of the study area was classified as agriculture, with bottomland hardwood forest the next largest habitat class. The thickness of a forest fragment was defined as the radius of the largest circle that can be inscribed in a fragment. Thickness was used in three ways. First, individual forest fragments were identified and selected based on ecological function using criteria we established. Second, individual fragments that were too small to support interior species, but large enough that if moderately augmented they could recover that function, were identified and selected. These augmentable fragments were further prioritized by adjacency to habitat that might be suitable for reforestation, namely agriculture. Third, watersheds were prioritized for conservation and augmentation based on the size and distributions of forest fragment thickness and area within each watershed.","language":"English","publisher":"Natural Areas Association","doi":"10.3375/0885-8608(2007)27[72:PBHFSF]2.0.CO;2","issn":"08858608","usgsCitation":"Carter, J., and Biagas, J., 2007, Prioritizing bottomland hardwood forest sites for protection and augmentation: Natural Areas Journal, v. 27, no. 1, p. 72-82, https://doi.org/10.3375/0885-8608(2007)27[72:PBHFSF]2.0.CO;2.","productDescription":"11 p.","startPage":"72","endPage":"82","numberOfPages":"11","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":242688,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arkansas","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.197265625,\n              33.89321737944089\n            ],\n            [\n              -90.087890625,\n              33.89321737944089\n            ],\n            [\n              -90.087890625,\n              36.16892253622743\n            ],\n            [\n              -92.197265625,\n              36.16892253622743\n            ],\n            [\n              -92.197265625,\n              33.89321737944089\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"27","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8c71e4b0c8380cd7e6bc","contributors":{"authors":[{"text":"Carter, J. 0000-0003-0110-0284 carterj@usgs.gov","orcid":"https://orcid.org/0000-0003-0110-0284","contributorId":81839,"corporation":false,"usgs":true,"family":"Carter","given":"J.","email":"carterj@usgs.gov","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":433915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Biagas, J. 0000-0001-5548-1970","orcid":"https://orcid.org/0000-0001-5548-1970","contributorId":51558,"corporation":false,"usgs":true,"family":"Biagas","given":"J.","affiliations":[],"preferred":false,"id":433914,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Pseudo-Eulerian and Lagrangian statistics were calculated from the low-pass-filtered drifter velocity data between September 2002 and December 2003. The structure of the mean circulation is determined with unprecedented high horizontal resolution by the new data. In particular, mean currents, velocity variance, and kinetic energy levels are shown to be maximal in the Western Adriatic Current (WAC). Separating data into seasons, we found that the mean kinetic energy is maximal in fall, with high values also in winter, while it is significantly weaker in summer. High-resolution Local Area Model Italy winds were used to relate the drifter velocities to the wind fields. The surface currents appear to be significantly influenced by the winds. The mean flow during the northeasterly bora regime shows an intensification of the across-basin recirculating currents. In addition, the WAC is strongly intensified both in intensity and in its offshore lateral extension. In the southeasterly sirocco regime, northward flow without recirculation dominates in the eastern half of the basin, while during northwesterly maestro the WAC is enhanced. Separating the data into low and high Po River discharge rates for low-wind conditions shows that the WAC and the velocity fluctuations in front of the Po delta are stronger for high Po River runoff. Lagrangian covariance, diffusivity, and integral time and space scales are larger in the along-basin direction and are maximal in the southern portion of the WAC.

Accurate prediction of ET is important during and beyond the implementation of the Comprehensive Everglades Restoration Plan (CERP). In the USDA's Everglades Agro-Hydrology Model (EAHM) the soil water intake is linked with the soil water redistribution, soil evaporation, plant transpiration, subsurface lateral flow and subsurface drainage to calculate daily root zone soil water content. Hydrometeorological data from three sites with different soil moisture content and vegetal cover were used to evaluate the EAHM ET routine. In general, the EAHM water balance sub-model simulated the daily ET with acceptable accuracy in the area with standing water (Everglades) while using the Penman method. However, in the area with grass cover, there was a discrepancy between the model simulated and measured ET using either the Penman or the Priestley-Taylor method. The results indicated that in the region with two distinct climate patterns: dry (low humidity, more wind, and less precipitation) and wet (high humidity, less wind and more rainfall) such as South Florida, a combination method like Penman should be used for prediction of daily ET. However, in order to improve the predictability of the ET methods, information about surface albedo is needed for land surfaces with grass vegetation during the growing season.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Environmental Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"10583912","usgsCitation":"Savabi, M., Cochrane, T., German, E., Ikiz, C., and Cockshutt, N., 2007, Modelingevapotranspirationina sub-tropical climate: Journal of Environmental Hydrology, v. 15, p. 1-15.","startPage":"1","endPage":"15","numberOfPages":"15","costCenters":[],"links":[{"id":242789,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5c5ee4b0c8380cd6fc35","contributors":{"authors":[{"text":"Savabi, M.R.","contributorId":25376,"corporation":false,"usgs":true,"family":"Savabi","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":433947,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cochrane, T.A.","contributorId":42447,"corporation":false,"usgs":true,"family":"Cochrane","given":"T.A.","email":"","affiliations":[],"preferred":false,"id":433948,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"German, E.","contributorId":45133,"corporation":false,"usgs":true,"family":"German","given":"E.","affiliations":[],"preferred":false,"id":433950,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ikiz, C.","contributorId":101901,"corporation":false,"usgs":true,"family":"Ikiz","given":"C.","email":"","affiliations":[],"preferred":false,"id":433951,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cockshutt, N.","contributorId":43187,"corporation":false,"usgs":true,"family":"Cockshutt","given":"N.","email":"","affiliations":[],"preferred":false,"id":433949,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

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}]}}

Large-scale geologic mapping, talus production data, rock-mass-quality measurements, and historical rockfall data indicate that rockfall susceptibility is correlated with limb dip and curvature of the folded, cliff-forming Mississippian limestones. On fold limbs, rockfall susceptibility increases as dip increases. This relation is controlled by several factors, including an increase in adverse dip conditions and apertures of discontinuities, and shearing by flexural slip during folding that has reduced the friction angles of discontinuities by smoothing surface asperities. Susceptibility is greater in fold hinge zones than on adjacent limbs primarily because there are greater numbers of discontinuities in hinge zones. We speculate that susceptibility increases in hinge zones as fold curvature becomes tighter.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Natural Hazards and Earth System Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"European Geosciences Union","doi":"10.5194/nhess-7-1-2007","issn":"15618633","usgsCitation":"Coe, J.A., and Harp, E.L., 2007, Influence of tectonic folding on rockfall susceptibility, American Fork Canyon, Utah, USA: Natural Hazards and Earth System Sciences, v. 7, no. 1, p. 1-14, https://doi.org/10.5194/nhess-7-1-2007.","startPage":"1","endPage":"14","numberOfPages":"14","costCenters":[],"links":[{"id":477202,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/nhess-7-1-2007","text":"Publisher Index Page"},{"id":242530,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267915,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5194/nhess-7-1-2007"}],"volume":"7","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-01-10","publicationStatus":"PW","scienceBaseUri":"505a3b84e4b0c8380cd625e0","contributors":{"authors":[{"text":"Coe, J.

Data were collected during the 1998 and 1999 breeding seasons, using point count surveys of foraging birds at 40 sites along the river's banks, and using aerial strip transect counts throughout the estuary for terns. In 1998, terns selected tidal flats and sites with roosting beaches nearby for foraging, making greater use of the marine/mixing zone of the estuary later in the season, particularly areas near the ocean jetties. In 1999, cormorants selected foraging sites in freshwater along the main channel with pile dikes present, particularly early in the season. Foraging trends in the other year for each species were generally similar to the above but usually not significant. During aerial surveys we observed 50% of foraging and commuting terns within 8 km of the Rice Island colony, and <span>≤</span> 5% of activity occurred <span>≥</span> 27 km from this colony in both years. Disproportionately greater cormorant foraging activity at pile dikes may indicate greater vulnerability of salmonids to predation at those features. Colony relocations to sites at sufficient distance from areas of relatively high salmonid abundance may be a straightforward means of reducing impacts of avian predation on salmonids than habitat alterations within the Columbia River estuary, at least for terns.&nbsp;</p>","language":"English","publisher":"BioOne Complete","doi":"10.3955/0029-344X-81.2.91","usgsCitation":"Lyons, D., Roby, D., and Collis, K., 2007, Foraging patterns of Caspian terns and double-crested cormorants in the Columbia River estuary: Northwest Science, v. 81, no. 2, p. 91-103, https://doi.org/10.3955/0029-344X-81.2.91.","productDescription":"13 p.","startPage":"91","endPage":"103","costCenters":[{"id":517,"text":"Oregon Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":242659,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon, Washington","otherGeospatial":"Columbia River estuary","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.10705566406249,\n              46.22260258751594\n            ],\n            [\n              -124.00680541992188,\n              46.224502800461025\n            ],\n            [\n              -123.90930175781249,\n              46.22260258751594\n            ],\n            [\n              -123.90930175781249,\n              46.3127900695348\n            ],\n            [\n              -124.10705566406249,\n              46.3127900695348\n            ],\n            [\n              -124.10705566406249,\n              46.22260258751594\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"81","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1300e4b0c8380cd5449e","contributors":{"authors":[{"text":"Lyons, Donald E.","contributorId":20119,"corporation":false,"usgs":true,"family":"Lyons","given":"Donald E.","affiliations":[],"preferred":false,"id":434222,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roby, D.D. 0000-0001-9844-0992","orcid":"https://orcid.org/0000-0001-9844-0992","contributorId":70944,"corporation":false,"usgs":true,"family":"Roby","given":"D.D.","affiliations":[],"preferred":false,"id":434223,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Collis, K.","contributorId":90910,"corporation":false,"usgs":true,"family":"Collis","given":"K.","email":"","affiliations":[],"preferred":false,"id":434224,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Plateau and Midcontinent have the necessary ingredients for landslides including sufficient relief, steep slope gradients, Pennsylvanian and Permian cyclothems that weather into fine-grained soils containing considerable clay, and adequate precipitation. One commonly used parameter in landslide-hazard analysis that is in need of further investigation is plan curvature. Plan curvature is the curvature of the hillside in a horizontal plane or the curvature of the contours on a topographic map. Hillsides can be subdivided into regions of concave outward plan curvature called hollows, convex outward plan curvature called noses, and straight contours called planar regions. Statistical analysis of plan-curvature and landslide datasets indicate that hillsides with planar plan curvature have the highest probability for landslides in regions dominated by earth flows and earth slides in clayey soils (CH and CL). The probability of landslides decreases as the hillsides become more concave or convex. Hollows have a slightly higher probability for landslides than noses. In hollows landslide material converges into the narrow region at the base of the slope. The convergence combined with the cohesive nature of fine-grained soils creates a buttressing effect that slows soil movement and increases the stability of the hillside within the hollow. Statistical approaches that attempt to determine landslide hazard need to account for the complex relationship between plan curvature, type of landslide, and landslide susceptibility. ?? 2007 Elsevier B.V.

Analysis of the Jacobian matrix (or the difference method) provides a measure of dispersion curve sensitivity to earth properties. Vs is the dominant influence for the fundamental mode (Xia et al., 1999) and higher modes (Xia et al., 2003) of dispersion curves in a high frequency range (>2 Hz) followed by layer thickness. These characteristics are the foundation of determining S-wave velocities by inversion of Rayleigh-wave data. More applications of surface-wave techniques show an anomalous velocity layer such as a high-velocity layer (HVL) or a low-velocity layer (LVL) commonly exists in near-surface materials. Spatial location (depth) of an anomalous layer is usually the most important information that surface-wave techniques are asked to provide. Understanding and correctly defining the sensitivity of high-frequency Rayleigh-wave data due to depth of an anomalous velocity layer are crucial in applying surface-wave techniques to obtain a Vs profile and/or determine the depth of an anomalous layer. Because depth is not a direct earth property of a layered model, changes in depth will result in changes in other properties. Modeling results show that sensitivity at a given depth calculated by the difference method is dependent on the Vs difference (contrast) between an anomalous layer and surrounding layers. The larger the contrast is, the higher the sensitivity due to depth of the layer. Therefore, the Vs contrast is a dominant contributor to sensitivity of Rayleigh-wave data due to depth of an anomalous layer. Modeling results also suggest that the most sensitive depth for an HVL is at about the middle of the depth to the half-space, but for an LVL it is near the ground surface. ?? 2007 Society of Exploration Geophysicists.","largerWorkTitle":"SEG Technical Program Expanded Abstracts","language":"English","doi":"10.1190/1.2792614","issn":"10523812","usgsCitation":"Xia, J., Miller, R., and Ivanov, J., 2007, Sensitivity of high-frequency Rayleigh-wave data revisited, <i>in</i> SEG Technical Program Expanded Abstracts, v. 26, no. 1, p. 1142-1146, https://doi.org/10.1190/1.2792614.","startPage":"1142","endPage":"1146","numberOfPages":"5","costCenters":[],"links":[{"id":214781,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1190/1.2792614"},{"id":242532,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-09-14","publicationStatus":"PW","scienceBaseUri":"505b8d30e4b08c986b3182c1","contributors":{"authors":[{"text":"Xia, J.","contributorId":63513,"corporation":false,"usgs":true,"family":"Xia","given":"J.","email":"","affiliations":[],"preferred":false,"id":434337,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, R.

The methanogens utilized carbon dioxide derived from organic matter in the marginal marine sediments and hydrogen from&nbsp;<i>in situ</i>&nbsp;pore water to generate methane. The most recent USGS assessment of the shallow gas resources of eastern Montana used a petroleum systems approach, identifying the critical components of a petroleum system (source rock, reservoir rock, seal rock, and trap) and their temporal relationships. As a part of this effort, geochemical data from natural gas wells and associated formation waters were used to identify two microbial gas systems and the timing of methanogenesis.</p>\n<p class=\"indent\">Two microbial gas families are identified in north-central Montana based on stable carbon isotope and gas composition. The Montana Group gas family has heavier &delta;<span>13</span>C methane values, slightly lighter &delta;D methane values, and a lower carbon dioxide and nitrogen content than the Colorado Group gas family. The two gas families may reflect, in part, the source rock depositional environments, with the Colorado Group rocks representing a more offshore marine depositional environment and the Montana Group rocks representing proximal marine, deltaic and nonmarine depositional environments. Assuming the gas families reflect only source rock characteristics, two microbial petroleum systems can be defined. The first petroleum system, called the Colorado Group microbial gas system, consists of Colorado Group rocks with the shales in the Belle Fourche Formation, Greenhorn Formation, and the Carlile Shale as the presumed source rocks and the interbedded Phillips and Bowdoin sandstones and the Greenhorn Formation limestones as reservoirs. The second petroleum system, called the Montana Group microbial gas system, consists of the Montana Group rocks that include the Gammon Shale and possibly the Claggett Shale as source rocks and the Eagle Sandstone and the Judith River Formation as reservoirs. The Niobrara Formation is tentatively placed in the former system. The geographic extent of the two microbial systems is much larger than the study area and includes an area at least from the Alberta basin to the northwest to the Powder River basin to the southeast. Upper Cretaceous microbial gas accumulations have been recognized along these basin margins at burial depths less than 3000 ft, but have not been recognized within the deeper parts of the basins because subsequent charge of thermogenic oil and gas masks the preexisting microbial gas accumulations.</p>\n<p class=\"indent\">Methanogenesis began soon after the deposition (early-stage methanogenesis) of the Cenomanian to Campanian source sediments, and was either sustained or rejuvenated by episodic meteoric water influx until sometime in the Paleogene. Methanogenesis probably continued until CO<span>2</span>&nbsp;and hydrogen were depleted or the pore size was compacted to below tolerance levels of the methanogens. The composition of the Montana and Colorado Group gases and coproduced formation water precludes a scenario of late-stage methanogenesis like the Antrim gas system in the Michigan basin. Some portion of the methane charge was originally dissolved in the pore waters, and subsequent reduction in hydrostatic pressure caused the methane to exsolve and migrate into local stratigraphic and structural traps. The critical moment of the microbial gas systems is this timing of exsolution rather than the time of generation (methanogenesis). Other studies suggest that the reduction in hydrostatic pressure may have been caused by multiple geologic events including the lowering of sea level in the Late Cretaceous, and subsequent uplift and erosion events, the youngest of which began about 5 Ma.</p>","language":"English","publisher":"Rocky Mountain Association of Geologists","publisherLocation":"Denver, CO","usgsCitation":"Lillis, P.G., 2007, Upper cretaceous microbial petroleum systems in north-central Montana: Mountain Geologist, v. 44, no. 1, p. 11-35.","productDescription":"25 p.","startPage":"11","endPage":"35","numberOfPages":"25","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":241566,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":299336,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://archives.datapages.com/data/mountain-geologist-rmag/data/044/044001/11_rmag-mg440011.htm"}],"country":"United States","state":"Montana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -113.499755859375,\n              46.521075663842836\n            ],\n            [\n              -113.499755859375,\n              49.009050809382046\n            ],\n            [\n              -106.490478515625,\n              49.009050809382046\n            ],\n            [\n              -106.490478515625,\n              46.521075663842836\n            ],\n            [\n              -113.499755859375,\n              46.521075663842836\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"44","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbd50e4b08c986b328f6d","contributors":{"authors":[{"text":"Lillis, Paul G. 0000-0002-7508-1699 plillis@usgs.gov","orcid":"https://orcid.org/0000-0002-7508-1699","contributorId":1817,"corporation":false,"usgs":true,"family":"Lillis","given":"Paul","email":"plillis@usgs.gov","middleInitial":"G.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":437661,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Our main objective was to estimate genus- and family-level indicator values (IVs) from a data set of macroinvertebrate communities, chemical, and physical stressors collected in a consistent manner throughout the United States. We then demonstrated an application of these IVs to detect alterations in benthic macroinvertebrate assemblages along gradients of urbanization in New England and Alabama. Principal components analysis (PCA) was used to create synthetic gradients of chemical stressors, for which genus- and family-level weighted averages (WAs) were calculated. Based on results of PCA, WAs were calculated for three synthetic gradients (ionic concentration, nutrient concentration, and dissolved oxygen/water temperature) and two uncorrelated physical variables (suspended sediment concentration and percent fines). Indicator values for each stress gradient were subsequently created by transforming WAs into ten ordinal ranks based on percentiles of values across all taxa. Mean IVs of genera and families were highly correlated to road density in Alabama and New England, and supported the conclusions of independent assessments of the chemical and physical stressors acting in each geographic area. Family IVs were nearly as responsive to urbanization as genus IVs. The limitations of widespread use of these IVs are discussed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Indicators","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecolind.2005.09.005","issn":"1470160X","usgsCitation":"Carlisle, D., Meador, M.R., Moulton, S., and Ruhl, P.M., 2007, Estimation and application of indicator values for common macroinvertebrate genera and families of the United States: Ecological Indicators, v. 7, no. 1, p. 22-33, https://doi.org/10.1016/j.ecolind.2005.09.005.","startPage":"22","endPage":"33","numberOfPages":"12","costCenters":[],"links":[{"id":213954,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecolind.2005.09.005"},{"id":241631,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0b70e4b0c8380cd52710","contributors":{"authors":[{"text":"Carlisle, D.M.","contributorId":81059,"corporation":false,"usgs":true,"family":"Carlisle","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":437675,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meador, M.

Concurrent declines in abundance of native fishes have been reported in aquatic systems where flathead catfish have been introduced. To evaluate the potential impact of this invasive species on the native fish community we developed an ecosystem simulation model (including flathead catfish) based on empirical data collected from a North Carolina coastal river. The model results suggest that flathead catfish suppress native fish community biomass by 5-50% through both predatory and competitive interactions. However, our model suggests these reductions could be mitigated through sustained exploitation of flathead catfish by recreational or commercial fishers at rates equivalent to those for native flathead catfish populations (annual exploitation = 6-25%). These findings demonstrate the potential for using directed harvest of an invasive species to assist in restoring native communities. ??

One published report noted the presence of the rainbow whiptail (</span><i>Cnemidophorus lemniscatus</i><span>) on Cayo Cochino Peque&ntilde;o, but nothing is known about the biology of this insular population. During a part of the dry season in July and August 2004, we used drift fences, pitfall traps, and separate observational transects to elucidate the distribution and habitat use of&nbsp;</span><i>C. lemniscatus</i><span>&nbsp;on the island. The only population of this species was located in a narrow coastal zone (width to 60 m and length to 450 m) on the southern half of the eastern windward side of the island. We analyzed the percentage of the canopy cover and the percentage of 4 ground coverage types along 2 transects 200 m long in this area to understand the basis of the suitability of the habitat for&nbsp;</span><i>C. lemniscatus</i><span>. Descriptively, the area harboring this species on Cayo Cochino Peque&ntilde;o consisted of the remnants of a coconut palm grove with low-lying herbaceous vegetation and grasses, in which a mosaic of small, open areas of sandy soil and coral fragments, with or without accumulations of debris, were the foci of lizard activities. Also observed in this habitat were 2 individuals of the brown racer (</span><i>Dryadophis melanolomus</i><span>), an actively foraging snake and likely predator on&nbsp;</span><i>C. lemniscatus</i><span>. Data obtained on rainbow whiptails captured in pitfall traps and subsequently released were used to determine the size and color patterns of hatchlings and adult males and females.</span></p>","language":"English","publisher":"Southwestern Association of Naturalists","doi":"10.1894/0038-4909(2007)52[38:DHSACP]2.0.CO;2","issn":"00384909","usgsCitation":"Montgomery, C.E., Reed, R., Shaw, H.J., Boback, S.M., and Walker, J., 2007, Distribution, habitat, size, and color pattern of Cnemidophorus lemniscatus (Sauria: Teiidae) on Cayo Cochino Pequeño, Honduras: Southwestern Naturalist, v. 52, no. 1, p. 38-45, https://doi.org/10.1894/0038-4909(2007)52[38:DHSACP]2.0.CO;2.","productDescription":"8 p.","startPage":"38","endPage":"45","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":241531,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213866,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1894/0038-4909(2007)52[38:DHSACP]2.0.CO;2"}],"country":"Honduras","otherGeospatial":"Cayo Cochino Pequeno","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -86.5080213546753,\n              15.951921386704994\n            ],\n            [\n              -86.5080213546753,\n              15.966857959328598\n            ],\n            [\n              -86.496262550354,\n              15.966857959328598\n            ],\n            [\n              -86.496262550354,\n              15.951921386704994\n            ],\n            [\n              -86.5080213546753,\n              15.951921386704994\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"52","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a031fe4b0c8380cd50355","contributors":{"authors":[{"text":"Montgomery, Chad E.","contributorId":95699,"corporation":false,"usgs":false,"family":"Montgomery","given":"Chad","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":437811,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reed, Robert N.","contributorId":10115,"corporation":false,"usgs":true,"family":"Reed","given":"Robert N.","affiliations":[],"preferred":false,"id":437809,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shaw, Hayley J.","contributorId":11836,"corporation":false,"usgs":true,"family":"Shaw","given":"Hayley","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":437807,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Boback, Scott M.","contributorId":69370,"corporation":false,"usgs":false,"family":"Boback","given":"Scott","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":437810,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Walker, James M.","contributorId":30180,"corporation":false,"usgs":true,"family":"Walker","given":"James M.","affiliations":[],"preferred":false,"id":437808,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The consortium is organized into a system of Regional Centers, each of which is responsible for glaciers in their region of expertise. Specialized needs for mapping glaciers in a distributed analysis environment require considerable work developing software tools: terrain classification emphasizing snow, ice, water, and admixtures of ice with rock debris; change detection and analysis; visualization of images and derived data; interpretation and archival of derived data; and analysis to ensure consistency of results from different Regional Centers. A global glacier database has been designed and implemented at the National Snow and Ice Data Center (Boulder, CO); parameters have been expanded from those of the World Glacier Inventory (WGI), and the database has been structured to be compatible with (and to incorporate) WGI data. The project as a whole was originated, and has been coordinated by, the US Geological Survey (Flagstaff, AZ), which has also led the development of an interactive tool for automated analysis and manual editing of glacier images and derived data (GLIMSView). This article addresses remote sensing and Geographic Information Science techniques developed within the framework of GLIMS in order to fulfill the goals of this distributed project. Sample applications illustrating the developed techniques are also shown. ?? 2006 Elsevier Ltd.
