This study used SEEDSCAPE, a recently modified gap model designed for cultivated land mosaics in the Great Plains, to simulate the effects of climate change on the dynamics of such linear forests. We simulated the dynamics of windbreaks with different initial planting species richness and widths (light changes as the selected resulting factor) using current climate data and nested regional circulation models (RegCMs). Results indicated that (1) it took 70-80 simulation years for the linear forests to reach a steady state under both normal (present-day) and warming climates; (2) warming climates would reduce total aboveground tree biomass and the spatial variation in biomass but increase dominance in the linear forests, especially in the upland forests; (3) linear forests with higher planting species richness and smaller width produced higher aboveground tree biomass per unit area; and (4) same species performed very differently with different climate scenarios, initial planting diversity, and forest widths. Although the model still needs further improvements (e.g., the effects of understory species should be included), the model can serve as a useful tool in modeling the succession of linear forests in human-dominated land mosaics under changing climates and may also have significant practical implications in other systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Forest Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Guo, Q., Brandle, J., Schoeneberger, M., and Buettner, D., 2004, Simulating the dynamics of linear forests in Great Plains agroecosystems under changing climates: Canadian Journal of Forest Research, v. 34, p. 2564-2572.","productDescription":"9 p.","startPage":"2564","endPage":"2572","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":128502,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"34","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f8e4b07f02db5f30a9","contributors":{"authors":[{"text":"Guo, Q.","contributorId":67039,"corporation":false,"usgs":true,"family":"Guo","given":"Q.","email":"","affiliations":[],"preferred":false,"id":324398,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brandle, J.R.","contributorId":40152,"corporation":false,"usgs":true,"family":"Brandle","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":324396,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schoeneberger, M.M.","contributorId":64593,"corporation":false,"usgs":true,"family":"Schoeneberger","given":"M.M.","email":"","affiliations":[],"preferred":false,"id":324397,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Buettner, D.","contributorId":69922,"corporation":false,"usgs":true,"family":"Buettner","given":"D.","email":"","affiliations":[],"preferred":false,"id":324399,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

However, processes for accurate land-cover classification over large regions are still evolving. We identified inconsistencies in the National Land Cover Dataset 1992, the most current and available representation of land cover for the conterminous United States. We also report means to address these inconsistencies in a bird-habitat model. We used a Geographic Information System (GIS) to position a regular grid (or lattice) over the upper midwestern United States and summarized the proportion of individual land covers in each cell within the lattice. These proportions were then mapped back onto the lattice, and the resultant lattice was compared to satellite paths, state borders, and regional map classification units. We observed mapping inconsistencies at the borders between mapping regions, states, and Thematic Mapper (TM) mapping paths in the upper midwestern United States, particularly related to grass I and-herbaceous, emergent-herbaceous wetland, and small-grain land covers. We attributed these discrepancies to differences in image dates between mapping regions, suboptimal image dates for distinguishing certain land-cover types, lack of suitable ancillary data for improving discrimination for rare land covers, and possibly differences among image interpreters. To overcome these inconsistencies for the purpose of modeling regional populations of birds, we combined grassland-herbaceous and pasture-hay land-cover classes and excluded the use of emergent-herbaceous and small-grain land covers. We recommend that users of digital land-cover data conduct similar assessments for other regions before using these data for habitat evaluation. Further, caution is advised in using these data in the analysis of regional land-cover change because it is not likely that future digital land-cover maps will repeat the same problems, thus resulting in biased estimates of change.</p>","language":"English","publisher":"U.S. Fish and Wildlife Service","doi":"10.2193/0091-7648(2004)032[0970:CACTRU]2.0.CO;2","issn":"00917648","usgsCitation":"Thogmartin, W.E., Gallant, A.L., Knutson, M.G., Fox, T.J., and Suarez, M.J., 2004, Commentary: A cautionary tale regarding use of the National Land Cover Dataset 1992: Wildlife Society Bulletin, v. 32, no. 3, p. 970-978, https://doi.org/10.2193/0091-7648(2004)032[0970:CACTRU]2.0.CO;2.","productDescription":"9 p.","startPage":"970","endPage":"978","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":201735,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae6e2","contributors":{"authors":[{"text":"Thogmartin, Wayne E. 0000-0002-2384-4279 wthogmartin@usgs.gov","orcid":"https://orcid.org/0000-0002-2384-4279","contributorId":2545,"corporation":false,"usgs":true,"family":"Thogmartin","given":"Wayne","email":"wthogmartin@usgs.gov","middleInitial":"E.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":324613,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gallant, Alisa L. 0000-0002-3029-6637 gallant@usgs.gov","orcid":"https://orcid.org/0000-0002-3029-6637","contributorId":2940,"corporation":false,"usgs":true,"family":"Gallant","given":"Alisa","email":"gallant@usgs.gov","middleInitial":"L.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":324612,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knutson, Melinda G.","contributorId":74338,"corporation":false,"usgs":true,"family":"Knutson","given":"Melinda","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":324615,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fox, Timothy J. 0000-0002-6167-3001 tfox@usgs.gov","orcid":"https://orcid.org/0000-0002-6167-3001","contributorId":1701,"corporation":false,"usgs":true,"family":"Fox","given":"Timothy","email":"tfox@usgs.gov","middleInitial":"J.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":324614,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Suarez, Manuel J. msuarez@usgs.gov","contributorId":3086,"corporation":false,"usgs":true,"family":"Suarez","given":"Manuel","email":"msuarez@usgs.gov","middleInitial":"J.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":324616,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Aquifer tests that are performed in these settings also are frequently affected by leakage from adjacent confining units. Finite-difference models such as MODFLOW are convenient tools for estimating the hydraulic characteristics of the stressed aquifer and adjacent confining units but are poor tools for the estimation of lateral anisotropy. This limitation of finite-difference methods can be overcome by application of the spin method, a technique whereby the positions of the observation wells are rotated about the production well to estimate anisotropy and orientation. Formal parameter estimation is necessary to analyze aquifer tests because of the number of parameters that are estimated. As a test, transmissivity, anisotropy, and orientation were successfully estimated for a simple hypothetical problem with known properties. The technique also was applied to estimate hydraulic properties of the Santee Limestone/Black Mingo (SL/BM) aquifer and a leaky confining unit beneath Charleston, South Carolina. A 9-day aquifer test with an average discharge of 6441/min was analyzed numerically. Drawdowns in the SL/BM aquifer and confining unit were simulated with a 12-layer MODFLOW model that was discretized into 81 rows of 81 columns. Simulated drawdowns at seven observation wells that ranged from 23 to 2700 m from the production well were matched to measured drawdowns.

While similar in some respects to the great escarpments along other passive margins, which have evolved by erosion following rifting, its youthful topographic expression has inspired proposals of Cenozoic tectonic rejuvenation in eastern North America. To better understand the post-orogenic and post-rift geomorphic evolution of passive margins, we have examined the origin of this landform using low-temperature thermochronometry and manipulation of topographic indices. Apatite (U-Th)/He and fission-track analyses along transects across the escarpment reveal a younging trend towards the coast. This pattern is consistent with other great escarpments and fits with an interpretation of having evolved by prolonged erosion, without the requirement of tectonic rejuvenation. Measured ages are also comparable specifically to those measured along other great escarpments that are as much as 100 Myr younger. This suggests that erosional mechanisms that maintain rugged escarpments in the early post-rift stages may remain active on ancient passive margins for prolonged periods. The precise erosional evolution of the escarpment is less clear, however, and several end-member models can explain the data. Our preferred model, which fits with all data, involves a significant degree of erosional escarpment retreat in the Cenozoic. Although this suggests that early onset of topographic stability is not required of passive margin evolution, more data are required to better constrain the details of the escarpment's development.&nbsp;</p>","language":"English","publisher":"Wiley Online Library","doi":"10.1111/j.1365-2117.2003.00219.x","usgsCitation":"Spotila, J., Bank, G., Reiners, P., Naeser, C.W., Naeser, N.D., and Henika, B., 2004, Origin of the Blue Ridge escarpment along the passive margin of Eastern North America: Basin Research, v. 16, no. 1, p. 41-63, https://doi.org/10.1111/j.1365-2117.2003.00219.x.","productDescription":"23 p.","startPage":"41","endPage":"63","costCenters":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"links":[{"id":238268,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Blue Ridge escarpment","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -86.6162109375,\n              34.63320791137959\n            ],\n            [\n              -83.7158203125,\n              34.70549341022544\n            ],\n            [\n              -81.474609375,\n              36.24427318493909\n            ],\n            [\n              -78.22265625,\n              38.685509760012\n            ],\n            [\n              -76.201171875,\n              41.178653972331674\n            ],\n            [\n              -72.8173828125,\n              41.902277040963696\n            ],\n            [\n              -68.9501953125,\n              44.933696389694674\n            ],\n            [\n              -68.6865234375,\n              45.98169518512228\n            ],\n            [\n              -76.2451171875,\n              42.71473218539458\n            ],\n            [\n              -86.6162109375,\n              34.63320791137959\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"16","issue":"1","noUsgsAuthors":false,"publicationDate":"2003-12-22","publicationStatus":"PW","scienceBaseUri":"505a70f7e4b0c8380cd76384","contributors":{"authors":[{"text":"Spotila, J.A.","contributorId":41163,"corporation":false,"usgs":true,"family":"Spotila","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":414121,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bank, G.C.","contributorId":97701,"corporation":false,"usgs":true,"family":"Bank","given":"G.C.","email":"","affiliations":[],"preferred":false,"id":414123,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reiners, P.W.","contributorId":34241,"corporation":false,"usgs":true,"family":"Reiners","given":"P.W.","email":"","affiliations":[],"preferred":false,"id":414120,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Naeser, C.

The study incorporated multiple quality controls and included a control for virus recovery during the sampling procedure as well as controls to detect potentially false-negative and false-positive data.

All five sites were positive for viruses by both molecular and cell culture-based virus assays. Enteroviruses, reoviruses, rotaviruses, and hepatitis A viruses were detected, but the use of the quality controls proved critical for interpretation of the molecular data.

The photometric as well as textural differences between these regions can be explained in terms of topography (roughness) at and below the&nbsp;image resolution, without invoking significant variations in single-particle properties; the material on Borrelly's surface could be quite uniform. A statistical comparison of the digital elevation models (DEMs) produced from the three&nbsp;highest-resolution&nbsp;images independently at the USGS and DLR shows that their difference standard deviation is 120 m, consistent with a matching error of 0.20 pixel (similar to reported matching accuracies for many other stereo datasets). The DEMs also show some systematic differences attributable to manual versus automatic matching. Disk-resolved photometric modeling of the nucleus using the DEM shows that bright, smooth terrains on Borrelly are similar in&nbsp;roughness&nbsp;(Hapke roughness&nbsp;</span><i>θ</i><span>=20°) to C-type&nbsp;asteroid&nbsp;Mathilde but slightly brighter and more&nbsp;backscattering&nbsp;(single-scattering&nbsp;albedo&nbsp;</span><i>w</i><span>=0.056, Henyey–Greenstein phase parameter&nbsp;</span><i>g</i><span>=−0.32). The dark, mottled terrain is photometrically consistent with the same particles but with roughnesses as large as 60°. Intrinsically darker material is inconsistent with the phase behavior of these regions. Many local radiance variations are clearly related to topography, and others are consistent with a topographic explanation; one need not invoke albedo variations greater than a few tens of percent to explain the appearance of Borrelly.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.icarus.2003.07.009","issn":"00191035","usgsCitation":"Kirk, R.L., Howington-Kraus, E., Soderblom, L.A., Giese, B., and Oberst, J., 2004, Comparison of USGS and DLR topographic models of Comet Borrelly and photometric applications: Icarus, v. 167, no. 1, p. 54-69, https://doi.org/10.1016/j.icarus.2003.07.009.","productDescription":"16 p.","startPage":"54","endPage":"69","numberOfPages":"16","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":238355,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Comet Borrelly","volume":"167","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f849e4b0c8380cd4cfc7","contributors":{"authors":[{"text":"Kirk, Randolph L. 0000-0003-0842-9226 rkirk@usgs.gov","orcid":"https://orcid.org/0000-0003-0842-9226","contributorId":2765,"corporation":false,"usgs":true,"family":"Kirk","given":"Randolph","email":"rkirk@usgs.gov","middleInitial":"L.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":415169,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Howington-Kraus, Elpitha 0000-0001-5787-6554 ahowington@usgs.gov","orcid":"https://orcid.org/0000-0001-5787-6554","contributorId":2815,"corporation":false,"usgs":true,"family":"Howington-Kraus","given":"Elpitha","email":"ahowington@usgs.gov","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":415168,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Soderblom, Laurence A. 0000-0002-0917-853X lsoderblom@usgs.gov","orcid":"https://orcid.org/0000-0002-0917-853X","contributorId":2721,"corporation":false,"usgs":true,"family":"Soderblom","given":"Laurence","email":"lsoderblom@usgs.gov","middleInitial":"A.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":415166,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Giese, Bernd","contributorId":211337,"corporation":false,"usgs":false,"family":"Giese","given":"Bernd","email":"","affiliations":[],"preferred":false,"id":415167,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Oberst, Jurgen","contributorId":147983,"corporation":false,"usgs":false,"family":"Oberst","given":"Jurgen","email":"","affiliations":[],"preferred":false,"id":415170,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

For American black bears Ursus americanus, wariness and habitat inaccessibility further complicate quantification. Radio telemetry has been the primary technique used to examine activity, however, interpretation error and limitation on numbers of animals available to monitor prevent extrapolation to unmarked or untransmittered members of the population. We used remote cameras to quantify black bear activity patterns and examined differences by season, sex and reproductive class in the Alleghany Mountains of western Virginia, USA. We used 1,533 pictures of black bears taken during 1998-2002 for our analyses. Black bears generally were diurnal in summer and nocturnal in autumn with a vespertine activity peak during both seasons. Bear-hound training seasons occurred during September and may offer explanation for the observed shift towards nocturnal behaviour. We found no substantial differences in activity patterns between sex and reproductive classes. Use of remote cameras allowed us to efficiently sample larger numbers of individual animals and likely offered a better approximation of population-level activity patterns than individual-level, telemetry-based methodologies.","language":"English","publisher":"BioOne Complete","doi":"10.2981/wlb.2004.033","usgsCitation":"Bridges, A., Vaughan, M., and Klenzendorf, S., 2004, Seasonal variation in American black bear Ursus americanus activity patterns: Quantification via remote photography: Wildlife Biology, v. 10, no. 1, p. 277-284, https://doi.org/10.2981/wlb.2004.033.","productDescription":"8 p.","startPage":"277","endPage":"284","costCenters":[{"id":613,"text":"Virginia Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":234329,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Virginia","otherGeospatial":"Alleghany Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.419677734375,\n              36.848856608486905\n            ],\n            [\n              -78.123779296875,\n              36.848856608486905\n            ],\n            [\n              -78.123779296875,\n              38.685509760012\n            ],\n            [\n              -81.419677734375,\n              38.685509760012\n            ],\n            [\n              -81.419677734375,\n              36.848856608486905\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"10","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b88e7e4b08c986b316c19","contributors":{"authors":[{"text":"Bridges, A.S.","contributorId":49961,"corporation":false,"usgs":true,"family":"Bridges","given":"A.S.","email":"","affiliations":[],"preferred":false,"id":409065,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vaughan, M.R.","contributorId":74925,"corporation":false,"usgs":true,"family":"Vaughan","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":409066,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Klenzendorf, S.","contributorId":92842,"corporation":false,"usgs":true,"family":"Klenzendorf","given":"S.","email":"","affiliations":[],"preferred":false,"id":409067,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Ground water from these basins supplies a major part of the water requirements for the region. The continuous population growth in this area has resulted in ever-increasing demands on local ground-water resources. The collection and interpretation of ground-water data helps local water districts, military bases, and private citizens gain a better understanding of the ground-water flow systems, and consequently, water availability. During 2002, the U.S. Geological Survey and other agencies made approximately 2,500 water-level measurements in the Mojave River and Morongo ground-water basins. These data document recent conditions and, when compared with previous data, changes in ground-water levels. A water-level contour map was drawn using data from about 660 wells, providing coverage for most of the basins. Twenty-eight hydrographs show long-term (up to 70 years) water-level conditions throughout the basins, and 9 short-term (1997 to 2002) hydrographs show the effects of recharge and discharge along the Mojave River. In addition, a water-level-change map was compiled to compare 2000 and 2002 water levels throughout the basins. In the Mojave River ground-water basin, about 66 percent of the wells had water-level declines of 0.5 ft or more since 2000 and about 27 percent of the wells had water-level declines greater than 5 ft. The only area that had water-level increases greater than 5 ft that were not attributed to fluctuations in nearby pumpage was in the Harper Lake (dry) area where there has been a significant reduction in pumpage during the last decade. In the Morongo ground-water basin, about 36 percent of the wells had water-level declines of 0.5 ft or more and about 10 percent of the wells had water-level declines greater than 5 ft. Water-level increases greater than 5 ft were measured only in the Warren subbasin, where artificial-recharge operations have caused water levels to rise almost 60 ft since 2000.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/70046139","usgsCitation":"Smith, G., Stamos, C., and Predmore, S., 2004, 2002 Water-Table Contours of the Mojave River and the Morongo Ground-Water Basins, San Bernardino County, California, Dataset, https://doi.org/10.3133/70046139.","productDescription":"Dataset","costCenters":[],"links":[{"id":272922,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":272921,"type":{"id":16,"text":"Metadata"},"url":"https://water.usgs.gov/GIS/metadata/usgswrd/XML/cont2002.xml"}],"country":"United States","state":"California","county":"San Bernardino","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.662117,34.095200 ], [ -117.662117,35.057328 ], [ -116.035031,35.057328 ], [ -116.035031,34.095200 ], [ -117.662117,34.095200 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51a5d1e3e4b0605bc571ef84","contributors":{"authors":[{"text":"Smith, G.A. 0000-0001-8170-9924","orcid":"https://orcid.org/0000-0001-8170-9924","contributorId":38350,"corporation":false,"usgs":true,"family":"Smith","given":"G.A.","email":"","affiliations":[],"preferred":false,"id":479009,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stamos, C.L.","contributorId":14019,"corporation":false,"usgs":true,"family":"Stamos","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":479008,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Predmore, S.K.","contributorId":70676,"corporation":false,"usgs":true,"family":"Predmore","given":"S.K.","affiliations":[],"preferred":false,"id":479010,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We developed statistical models relating owl survival and productivity to forest cover types within the Roseburg Study Area in the Oregon Coast Range of Oregon, USA. We further combined these demographic parameters using a Leslie-type matrix to obtain an estimate of habitat fitness potential for each owl territory (<i>n</i> = 94). We used mark–recapture methods to develop models for survival and linear mixed models for productivity. We measured forest composition and landscape patterns at 3 landscape scales centered on nest and activity sites within owl territories using an aerial photo-based map and a Geographic Information System (GIS). We also considered additional covariates such as age, sex, and presence of barred owls (<i>Strix varia</i>), and seasonal climate variables (temperature and precipitation) in our models. We used Akaike's Information Criterion (AIC) to rank and compare models. Survival had a quadratic relationship with the amount of late- and mid-seral forests within 1,500 m of nesting centers. Survival also was influenced by the amount of precipitation during the nesting season. Only 16% of the variability in survival was accounted for by our best model, but 85% of this was due to the habitat variable. Reproductive rates fluctuated biennially and were positively related to the amount of edge between late- and mid-seral forests and other habitat classes. Reproductive rates also were influenced by parent age, amount of precipitation during nesting season, and presence of barred owls. Our best model accounted for 84% of the variability in productivity, but only 3% of that was due to the habitat variable. Estimates of habitat fitness potential (which may range from 0 to infinity) for the 94 territories ranged from 0.74 to 1.15 (<i>x̄</i> = 1.05, SE = 0.07). All but 1 territory had 95% confidence intervals overlapping 1.0, indicating a potentially stable population based on habitat pattern. Our results seem to indicate that while mid- and late-seral forests are important to owls, a mixture of these forest types with younger forest and nonforest may be best for owl survival and reproduction. Our results are consistent with those of researchers in northern California, USA, who used similar methods in their analyses. However, we believe that given the low variability in survival and productivity attributed to habitat, further study is needed to confirm our conclusions before they can be used to guide forest management actions for spotted owls.</p>","language":"English","publisher":"The Wildlife Society","doi":"10.2193/0022-541X(2004)068[1039:MDPONS]2.0.CO;2","usgsCitation":"Olson, G.S., Glenn, E.M., Anthony, R., Forsman, E.D., Reid, J.A., Loschl, P.J., and Ripple, W.J., 2004, Modeling demographic performance of northern spotted owls relative to forest habitat in Oregon: Journal of Wildlife Management, v. 68, no. 4, p. 1039-1053, https://doi.org/10.2193/0022-541X(2004)068[1039:MDPONS]2.0.CO;2.","productDescription":"15 p.","startPage":"1039","endPage":"1053","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":349254,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a61194be4b06e28e9c2597f","contributors":{"authors":[{"text":"Olson, Gail S.","contributorId":19884,"corporation":false,"usgs":true,"family":"Olson","given":"Gail","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":723220,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Glenn, Elizabeth M.","contributorId":150580,"corporation":false,"usgs":false,"family":"Glenn","given":"Elizabeth","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":723221,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Anthony, Robert G.","contributorId":61324,"corporation":false,"usgs":true,"family":"Anthony","given":"Robert G.","affiliations":[],"preferred":false,"id":723222,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Forsman, Eric D.","contributorId":96792,"corporation":false,"usgs":false,"family":"Forsman","given":"Eric","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":723223,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Reid, Janice A.","contributorId":98034,"corporation":false,"usgs":true,"family":"Reid","given":"Janice","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":723224,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Loschl, Peter J.","contributorId":7195,"corporation":false,"usgs":true,"family":"Loschl","given":"Peter","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":723225,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Ripple, William J.","contributorId":24271,"corporation":false,"usgs":true,"family":"Ripple","given":"William","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":723226,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

The grains show a variety of morphologies, including euhedral grains with conchoidal fractures and pits, and spherical grains with no crystal faces, probably because of abrasion. Inclusions are rare, but one grain contains Ca-Al amphilbole inclusions, and another contains an inclusion of chalcopyrite+bornite+pentlandite+heazlewoodite (Ni3S2) that is considered to have formed by a two-stage process of exsolution and crystallization from a once homogeneous Fe-Cu-Ni sulphide melt. All grains examined are solid solutions of Ru and Os with Ir (2.71-11.76 wt.%) and Pd (0.31-0.66 wt%). Their compositions are similar to laurite from ophiolitic rocks. The compositions show broad negative correlations between Os and Ir, between As and Ir, and between As (0.4-0.74 wt.%) and Se (140 to 240 ppm). Laurite with higher Os contains more Se and less Ir and As. The negative correlations between Se and As may be attributed to their occupancy of the S site, but the compositional variations of Os. Ir and As probably reflect the compositional variation of rocks where the crystals grew. Ratios of S/Se in laurite show a narrow spread from 1380 to 2300, which are similar to ratios for sulphides from the refractory sub-are mantle. Sulphur isotopic compositions of laurite are independent of chemical compositions and morphologies and are similar to the chondritic value of 0???. The data suggest that S in laurite has not undergone redox changes and originated from the refractory mantle. The data support the formation of laurite in the residual mantle or in a magnia generated from such a refractory mantle, followed by erosion after the obduction of the host ultramafic rocks. ?? 2004 The Mineralogical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mineralogical Magazine","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1180/0026461046820192","issn":"0026461X","usgsCitation":"Hattori, K., Cabri, L., Johanson, B., and Zientek, M.L., 2004, Origin of placer laurite from Borneo: Se and As contents, and S isotopic compositions: Mineralogical Magazine, v. 68, no. 2, p. 353-368, https://doi.org/10.1180/0026461046820192.","startPage":"353","endPage":"368","numberOfPages":"16","costCenters":[],"links":[{"id":209075,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1180/0026461046820192"},{"id":235267,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"2","noUsgsAuthors":false,"publicationDate":"2018-07-05","publicationStatus":"PW","scienceBaseUri":"505a70ece4b0c8380cd76343","contributors":{"authors":[{"text":"Hattori, K.H.","contributorId":29615,"corporation":false,"usgs":true,"family":"Hattori","given":"K.H.","email":"","affiliations":[],"preferred":false,"id":412749,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cabri, L.J.","contributorId":33895,"corporation":false,"usgs":true,"family":"Cabri","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":412750,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johanson, B.","contributorId":24539,"corporation":false,"usgs":true,"family":"Johanson","given":"B.","email":"","affiliations":[],"preferred":false,"id":412748,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zientek, M.

During late spring 1993-1995, the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP) sampled 490 wadeable streams in the mid-Atlantic Highlands (MAH) of the U.S. for a variety of physical, chemical and biological indicators of environmental condition. We used the resulting data set to evaluate the importance of differing levels of macroinvertebrate taxonomic resolution in bioassessments by comparing the ability of family versus genus to detect differences among sites classified by type and magnitude of human impact and by stream size. We divided the MAH into two physiographic regions: the Appalachian Plateau where mine drainage (MD) and acidic deposition are major stressors, and the Ridge and Valley where nutrient enrichment is a major stressor. Stream sites were classified into three or four impact classes based on water chemistry and habitat. We used stream order (first to third Strahler order) in each region as a measure of stream size. Ordination, 2 x 2 chi-square and biotic metrics were used to compare the ability of family and genus to detect differences among both stressor and size classes. 2. With one notable exception, there were only a small number of different genera per family (interquartile range = 1-4). Family Chironomidae, however, contained 123 different genera. As a result, significant information loss occurred when this group was only classified to family. The family Chironomidae did not discriminate among the predefined classes but many chironomid genera did: by chi-square analysis, 10 and 28 chironomid genera were significant in discriminating MD and nutrient impacts, respectively. 3. Family and genus data were similar in their ability to distinguish among the coarse impacts (e.g. most severe versus least severe impact classes) for all cases. Though genus data in many cases distinguished the subtler differences (e.g. mixed/moderate impacts versus high or low impacts) better than family, differences in significance levels between family and genus analyses were relatively minor. However, genus data detected differences among stream orders in ordination analyses that were not revealed at the family level. In the ordinations, both family and genus levels of analysis responded to similar suites of environmental variables. 4. Our results suggest that identification to the family level is sufficient for many bioassessment purposes. However, identifications to genus do provide more information in genera-rich families like Chironomidae. Genus or finer levels of identification are important for investigating natural history, stream ecology, biodiversity and indicator species. Decisions about the taxonomic level of identification need to be study specific and depend on available resources (cost) and study objectives.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2427.2004.01197.x","issn":"00465070","usgsCitation":"Waite, I., Herlihy, A., Larsen, D.P., Urquhart, N., and Klemm, D., 2004, The effects of macroinvertebrate taxonomic resolution in large landscape bioassessments: An example from the Mid-Atlantic Highlands, U.S.A.: Freshwater Biology, v. 49, no. 4, p. 474-489, https://doi.org/10.1111/j.1365-2427.2004.01197.x.","startPage":"474","endPage":"489","numberOfPages":"16","costCenters":[],"links":[{"id":478139,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2427.2004.01197.x","text":"Publisher Index Page"},{"id":235197,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209028,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2427.2004.01197.x"}],"volume":"49","issue":"4","noUsgsAuthors":false,"publicationDate":"2004-03-17","publicationStatus":"PW","scienceBaseUri":"505bab8ce4b08c986b322ef6","contributors":{"authors":[{"text":"Waite, I.R.","contributorId":41039,"corporation":false,"usgs":true,"family":"Waite","given":"I.R.","email":"","affiliations":[],"preferred":false,"id":412730,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Herlihy, A.T.","contributorId":31168,"corporation":false,"usgs":true,"family":"Herlihy","given":"A.T.","affiliations":[],"preferred":false,"id":412728,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Larsen, D.

A prominent jet dominated the near-nucleus coma and emanated roughly normal to the long axis of nucleus from a broad central cavity. We show it to have remained fixed in position for more than 34 hr, much longer than the 26-hr rotation period. This confirms earlier suggestions that it is co-aligned with the rotation axis. From a combination of fitting the nucleus light curve from approach images and the nucleus' orientation from stereo images at encounter, we conclude that the sense of rotation is right-handed around the main jet vector. The inferred rotation pole is approximately perpendicular to the long axis of the nucleus, consistent with a simple rotational state. Lacking an existing IAU comet-specific convention but applying a convention provisionally adopted for asteroids, we label this the north pole. This places the sub-solar latitude at ∼60° N at the time of the perihelion with the north pole in constant sunlight and thus receiving maximum average insolation.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.icarus.2003.07.008","issn":"00191035","usgsCitation":"Soderblom, L.A., Boice, D.C., Britt, D., Brown, R.H., Buratti, B.J., Kirk, R.L., Lee, M., Nelson, R., Oberst, J., Sandel, B., Stern, S., Thomas, N., and Yelle, R., 2004, Imaging Borrelly: Icarus, v. 167, no. 1, p. 4-15, https://doi.org/10.1016/j.icarus.2003.07.008.","productDescription":"12 p.","startPage":"4","endPage":"15","numberOfPages":"12","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":501662,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://stars.library.ucf.edu/facultybib2000/4810","text":"External Repository"},{"id":238442,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Comet Borrelly","volume":"167","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a387ee4b0c8380cd615b2","contributors":{"authors":[{"text":"Soderblom, Laurence A. 0000-0002-0917-853X lsoderblom@usgs.gov","orcid":"https://orcid.org/0000-0002-0917-853X","contributorId":2721,"corporation":false,"usgs":true,"family":"Soderblom","given":"Laurence","email":"lsoderblom@usgs.gov","middleInitial":"A.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":413397,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boice, D.

Temporal markers are needed for reservoir sediment studies to date sediment layers deposited between the 1963–64 cesium-137 peak and the present. For two of four reservoirs studied, anomalously low organic carbon concentrations were measured for a sample interval in the upper part of a sediment core. The anomalous interval was interpreted to have been deposited during the July 1993 flood that affected a large area of the upper Mississippi River Basin. Potentially, the July 1993 flood deposit may be used as a temporal marker in reservoir bottom sediments in parts of the basin affected by the flood. Several uncertainties remain regarding the viability of organic carbon as a temporal marker including the combination of flood, basin, and reservoir characteristics required to produce a recognizable organic carbon marker in the bottom sediment and the optimal sampling strategy needed to detect the marker in a sediment core. It is proposed that flood duration and basin size may be important factors as to whether or not an anomalous and detectable organic carbon layer is deposited in a reservoir.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/07438140409354160","usgsCitation":"Juracek, K.E., 2004, Flood-related, organic-carbon anomalies as possible temporal markers in reservoir bottom sediments: Lake and Reservoir Management, v. 20, no. 4, p. 309-321, https://doi.org/10.1080/07438140409354160.","productDescription":"13 p.","startPage":"309","endPage":"321","costCenters":[],"links":[{"id":234888,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Iowa, Kansas","otherGeospatial":"Coralville Lake, Milford Lake, Perry Lake, Tuttle Creek Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.71455383300781,\n              41.693936942282164\n            ],\n            [\n              -91.50238037109375,\n              41.693936942282164\n            ],\n            [\n              -91.50238037109375,\n              41.83989728790337\n            ],\n            [\n              -91.71455383300781,\n              41.83989728790337\n            ],\n            [\n              -91.71455383300781,\n              41.693936942282164\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -97.06008911132811,\n              39.05225165582583\n            ],\n            [\n              -96.85821533203125,\n              39.05225165582583\n            ],\n            [\n              -96.85821533203125,\n              39.2758527440647\n            ],\n            [\n              -97.06008911132811,\n              39.2758527440647\n            ],\n            [\n              -97.06008911132811,\n              39.05225165582583\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -96.77719116210938,\n              39.20246222588238\n            ],\n            [\n              -96.56707763671875,\n              39.20246222588238\n            ],\n            [\n              -96.56707763671875,\n              39.57817336212527\n            ],\n            [\n              -96.77719116210938,\n              39.57817336212527\n            ],\n            [\n              -96.77719116210938,\n              39.20246222588238\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.56594848632812,\n              39.09702872683213\n            ],\n            [\n              -95.35858154296875,\n              39.09702872683213\n            ],\n            [\n              -95.35858154296875,\n              39.297111003754964\n            ],\n            [\n              -95.56594848632812,\n              39.297111003754964\n            ],\n            [\n              -95.56594848632812,\n              39.09702872683213\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"20","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1172e4b0c8380cd53fce","contributors":{"authors":[{"text":"Juracek, Kyle E. 0000-0002-2102-8980 kjuracek@usgs.gov","orcid":"https://orcid.org/0000-0002-2102-8980","contributorId":2022,"corporation":false,"usgs":true,"family":"Juracek","given":"Kyle","email":"kjuracek@usgs.gov","middleInitial":"E.","affiliations":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":408012,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This framework consists of five supergroups that 1) are regionally inclusive and regionally applicable, 2) meaningfully reflect the overall stratigraphic and structural history of the Coastal Plains geologic province of the southeastern United States, and 3) create stratigraphic units that are readily mappable and useful at a regional level. Only the Marquesas Supergroup (Lower Cretaceous to lowest Upper Cretaceous) has been previously established. The Trent Supergroup (middle middle Eocene to basal lower Miocene) is an existing name here raised to supergroup rank. The Minden Supergroup (Middle? through Upper Jurassic), the Ancora Supergroup (Upper Cretaceous to lower middle Eocene), and the Nomini Supergroup (lower Miocene to Recent) are new stratigraphic concepts proposed herein. In order to bring existing groups and formations into accord with the supergroups described here, the following stratigraphic revisions are made. 1) The base of the Shark River Formation (Trent Supergroup) is moved upward. 2) The Old Church Formation is removed from the Chesapeake Group (Nomini Supergroup) and moved to the Trent Supergroup without group placement. 3) The Tiger Leap and Penney Farms formations are removed from the Hawthorn Group (Nomini Supergroup) and moved to the Trent Supergroup without group placement. 4) The Piney Point and Chickahominy formations are removed from the Pamunkey Group (Ancora Supergroup) and moved to the Trent Supergroup without group placement. 5) the Tallahatta Formation is removed from the Claiborne Group (Trent Supergroup) and placed within the Ancora Supergroup without group placement.","language":"English","issn":"00383678","usgsCitation":"Weems, R.E., Self-Trail, J., and Edwards, L.E., 2004, Supergroup stratigraphy of the Atlantic and Gulf Coastal Plains (Middle?

The data demonstrate that National Earthquake Hazards Reduction Program (NEHRP) site classes are a useful way of grouping stations according to site amplification. In general, the sites underlain by lower shear-wave velocities have higher amplification. The amplification on NEHRP class D sites exceeds a factor of 2 relative to an average of motions on class C sites. The amplifications are period dependent. They are in rough agreement with those from previous studies, but the new data show that the amplifications extend to at least 10 sec, periods longer than considered in previous studies. At periods longer than about 14 sec, all sites have motion of similar amplitude, and the ground displacements are similar in shape, polarization, and amplitude for all stations. The displacement ground motion is dominated by a series of four pulses, which are associated with the three subevents identified in inversion studies (the first pulse is composed of P waves from the first subevent). Most of the high-frequency ground motion is associated with the S waves from subevent 1. The pulses from subevents 1 and 2, with moment releases corresponding to M 7.1 and 7.0, are similar to the pulse of displacement radiated by the M 7.1 Hector Mine earthquake. The signature from the largest subevent (M 7.6) is more subdued than those from the first two subevents. The two largest pulses produce response spectra with peaks at a period of about 15 sec. The spectral shape at long periods is in good agreement with the recent 2003 NEHRP code spectra but is in poor agreement with the shape obtained from Eurocode 8.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120040606","usgsCitation":"Boore, D., 2004, Ground motion in Anchorage, Alaska, from the 2002 Denali fault earthquake: Site response and displacement pulses: Bulletin of the Seismological Society of America, v. 94, no. 6B, p.
