In relation to a proposed restoration of a wind-tidal flat system on the South Texas, USA Coast","docAbstract":"Wind-tidal flats are the dominant coastal wetland type in southern Texas USA. Succulent vascular plants are colonizing the flats in some locations, often where past dredge disposal along navigation channels and other activities have interrupted natural water communication between hypersaline bays and large areas of wind-tidal flats. The objective of this study was to test the feasibility of proposed removal of a causeway at Laguna Atascosa National Wildlife Refuge to restore the historic hydrologic regime and eradicate encroaching vascular plants, mostly Salicornia bigelovii, on the assumption that high sediment salt excluded these vascular plants under natural conditions. Assessment in spring 1998 of the density of Salicornia in relation to elevation and sediment salt of bare and vegetated zones on the vegetated flats on one side of the causeway and entirely barren flats with unimpaired connection to Laguna Madre on the other side of the causeway suggested that sediment salt >0.1 g ml-1 excluded vascular plants. However, bimonthly sampling in 1999-2000 revealed that sediment salt concentrations were >0.1 g ml-1 throughout the vegetated zone in July and more locally in the period of winter low water, with little impairment to established plants. This indicates that if control is desired, it must be exerted at germination and early establishment during and after fall high water. Continuous monitoring of water levels on either side of the causeway suggests that, even with removal of the causeway, flooding with hypersaline lagoon water will be too infrequent to counteract the freshening effect of a permanent hydraulic connection to the main agricultural drain of the lower Rio Grande Valley that has developed at the other end of the salt flat. Monitoring Salicornia distribution over six years documented huge variation between years but no trend toward increasing dominance of the flats. The results of this study illustrate that the most obvious alterations to a site may not be the most influential on function and that the scale of analysis may have to extend far beyond the site in space and time to evaluate a proposed restoration properly. ?? 2006, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/0277-5212(2006)26[649:AOTBOS]2.0.CO;2","issn":"02775212","usgsCitation":"Onuf, C., 2006, Aspects of the biology of Salicornia bigelovii torr.

This large estuary is impacted both by diverse anthropogenic activity and by extensive U-rich phosphatic deposits. Thus, the estuarine behavior of uranium may be examined relative to such known U enrichments and anthropogenic perturbations. Dissolved (< 0.45??m) uranium exhibited both removal and enrichment processes across the Alafia River/estuarine mixing zone relative to conservative mixing. Such non-conservative U behavior may be attributed to: i) physical mixing processes within the river; ii) U carrier phase reactivity; and/or iii) fluid exchange processes across sediment/water interface. In the bay proper, U concentrations were ?????2 to 3 times greater than those reported for other estuarine systems and are likely a result of erosional inputs from the extensive, underlying U-rich phosphatic deposits. Whereas dissolved U concentrations generally did not approach seawater values (13.6??nM) along the Alafia River salinity transect, water column U concentrations exceeded 16??nM in select regions of the bay. Within the hydrogeological framework of the bay, such enriched U may also be derived from advective fluid transport processes across the sediment/water interface, such as submarine groundwater discharge (SGD) or hyporheic exchange within coastal rivers. Pore water profiles of U in Tampa Bay show both a flux into and out of bottom sediments, and average, diffusive U pore water fluxes (Jdiff) ranged from - 82.0 to 116.6??mol d- 1. It is likely that negative U fluxes imply seawater entrainment or infiltration (i.e., submarine groundwater recharge), which may contribute to the removal of water column uranium. For comparison, a bay-wide, Ra-derived submarine groundwater discharge estimate for Tampa Bay (8??L m- 2 d- 1) yielded an average, advective (JSGD) U flux of 112.9??mol d- 1. In Tampa Bay, the estuarine distribution of U indicates a strong natural, geologic control that may also be influenced by enhanced fluid transport processes across the sediment/water interface. ?? 2006 Elsevier B.V.

The uniaxial compression method used to extract pore water from samples of tuffaceous borehole core was successful only for nonwelded tuff. An ultracentrifugation method was adopted to extract pore water from samples of the densely welded tuff of the proposed repository horizon. Tests were performed using both methods to determine the efficiency of pore water extraction and the potential effects on pore water chemistry. Test results indicate that uniaxial compression is most efficient for extracting pore water from nonwelded tuff, while ultracentrifugation is more successful in extracting pore water from densely welded tuff. Pore water splits collected from a single nonwelded tuff core during uniaxial compression tests have shown changes in pore water chemistry with increasing pressure for calcium, chloride, sulfate, and nitrate. Pore water samples collected from the intermediate pressure ranges should prevent the influence of re-dissolved, evaporative salts and the addition of ion-deficient water from clays and zeolites. Chemistry of pore water splits from welded and nonwelded tuffs using ultracentrifugation indicates that there is no substantial fractionation of solutes.","largerWorkTitle":"Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM","conferenceTitle":"11th International High Level Radioactive Waste Management Conference","conferenceDate":"30 April 2006 through 4 May 2006","conferenceLocation":"Las Vegas, NV","language":"English","isbn":"0894486918; 9780894486913","usgsCitation":"Scofield, K., 2006, Methods for pore water extraction from unsaturated zone tuff, Yucca Mountain, Nevada, <i>in</i> Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM, v. 2006, Las Vegas, NV, 30 April 2006 through 4 May 2006, p. 127-135.","startPage":"127","endPage":"135","numberOfPages":"9","costCenters":[],"links":[{"id":236396,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2006","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a55c7e4b0c8380cd6d2a2","contributors":{"authors":[{"text":"Scofield, K.M.","contributorId":51069,"corporation":false,"usgs":true,"family":"Scofield","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":418943,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We collected habitat use information on subyearlings in the Hanford Reach of the Columbia River during May 1994 and April-May 1995 using point abundance electrofishing. We analyzed measures of physical habitat using logistic regression to predict fish presence and absence in shoreline habitats. The difference between water temperature at the point of sampling and in the main river channel was the most important variable for predicting the presence and absence of subyearlings. Mean water velocities of 45 cm/s or less and habitats with low lateral bank slopes were also associated with a greater likelihood of subyearling presence. Intermediate-sized gravel and cobble substrates were significant predictors of fish presence, but small (&lt;32-mm) and boulder-sized (&gt;256-mm) substrates were not. Our rearing model was accurate at predicting fish presence and absence using jackknifing (80% correct) and classification of observations from an independent data set (76% correct).

This work outlines and tests a new ghost-node model-linking method for a refined \"child\" model that is contained within a larger and coarser \"parent\" model that is based on the iterative method of Steffen W. Mehl and Mary C. Hill (2002, Advances in Water Res., 25, p. 497-511; 2004, Advances in Water Res., 27, p. 899-912). The method is applicable to steady-state solutions for ground-water flow. Tests are presented for a homogeneous two-dimensional system that has matching grids (parent cells border an integer number of child cells) or nonmatching grids. The coupled grids are simulated by using the finite-difference and finite-element models MODFLOW and FEHM, respectively. The simulations require no alteration of the MODFLOW or FEHM models and are executed using a batch file on Windows operating systems. Results indicate that when the grids are matched spatially so that nodes and child-cell boundaries are aligned, the new coupling technique has error nearly equal to that when coupling two MODFLOW models. When the grids are nonmatching, model accuracy is slightly increased compared to that for matching-grid cases. Overall, results indicate that the ghost-node technique is a viable means to couple distinct models because the overall head and flow errors relative to the analytical solution are less than if only the regional coarse-grid model was used to simulate flow in the child model's domain.","largerWorkTitle":"Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM","conferenceTitle":"11th International High Level Radioactive Waste Management Conference","conferenceDate":"30 April 2006 through 4 May 2006","conferenceLocation":"Las Vegas, NV","language":"English","isbn":"0894486918; 9780894486913","usgsCitation":"James, S., Dickinson, J., Mehl, S., Hill, M.C., Leake, S.A., Zyvoloski, G., and Eddebbarh, A., 2006, New ghost-node method for linking different models with varied grid refinement, <i>in</i> Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM, v. 2006, Las Vegas, NV, 30 April 2006 through 4 May 2006, p. 338-344.","startPage":"338","endPage":"344","numberOfPages":"7","costCenters":[],"links":[{"id":236506,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2006","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a658be4b0c8380cd72c10","contributors":{"authors":[{"text":"James, S.C.","contributorId":103059,"corporation":false,"usgs":true,"family":"James","given":"S.C.","email":"","affiliations":[],"preferred":false,"id":418977,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dickinson, J.E.","contributorId":28790,"corporation":false,"usgs":true,"family":"Dickinson","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":418972,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mehl, S.W.","contributorId":84555,"corporation":false,"usgs":true,"family":"Mehl","given":"S.W.","affiliations":[],"preferred":false,"id":418975,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hill, M.

Comparison with field measurements showed good agreement both on a time scale of a single wave period as well as time averaged velocity moments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Coastal Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.coastaleng.2006.06.002","issn":"03783839","usgsCitation":"Elfrink, B., Hanes, D., and Ruessink, B., 2006, Parameterization and simulation of near bed orbital velocities under irregular waves in shallow water: Coastal Engineering, v. 53, no. 11, p. 915-927, https://doi.org/10.1016/j.coastaleng.2006.06.002.","productDescription":"13 p.","startPage":"915","endPage":"927","numberOfPages":"13","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":236404,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209712,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.coastaleng.2006.06.002"}],"volume":"53","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a74d0e4b0c8380cd77848","contributors":{"authors":[{"text":"Elfrink, B.","contributorId":98186,"corporation":false,"usgs":true,"family":"Elfrink","given":"B.","email":"","affiliations":[],"preferred":false,"id":419554,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hanes, D.M.","contributorId":22479,"corporation":false,"usgs":true,"family":"Hanes","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":419552,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ruessink, B.G.","contributorId":38029,"corporation":false,"usgs":true,"family":"Ruessink","given":"B.G.","email":"","affiliations":[],"preferred":false,"id":419553,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We compared habitats at normal operating pool elevation with habitats at drawdown to spillway crest elevation and drawdown to the historical natural river elevation for two flows (4,417 and 8,495 m3/s). Using two-dimensional hydrodynamic modeling and a predictive habitat model, we determined the quantity and spatial distribution of rearing habitat and predicted water velocities. We predicted that the most habitat area would occur under normal pool elevation, but 93% of habitat was located in the upper third of the reservoir. Although less habitat area was predicted under drawdown to the spillway crest and the natural river, it was distributed more homogeneously throughout the study area. Habitat connectivity, patch size, and percent of suitable shoreline were greatest under drawdown to the natural river elevation. Mean cross-sectional water velocity and the variation in velocity increased with increasing level of reservoir drawdown. Water velocities under drawdown to the natural river were about twice as high as those under drawdown to spillway crest and five times higher than those under normal pool. The variability in water velocity, which may provide cues to fish migration, was highest under drawdown to the natural river and lowest under normal pool elevation. The extent to which different drawdown scenarios would be effective in John Day Reservoir depends in part on restoring normative riverine processes.</p>","language":"English","publisher":"Taylor & Francis","doi":"10.1577/M06-018.1","issn":"02755947","usgsCitation":"Tiffan, K., Garland, R., and Rondorf, D., 2006, Predicted changes in subyearling fall Chinook salmon rearing and migratory habitat under two drawdown scenarios for John Day Reservoir, Columbia River: North American Journal of Fisheries Management, v. 26, no. 4, p. 894-907, https://doi.org/10.1577/M06-018.1.","productDescription":"14 p.","startPage":"894","endPage":"907","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":487580,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.osti.gov/biblio/2506883","text":"External Repository"},{"id":236403,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209711,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/M06-018.1"}],"country":"United States","state":"Oregon, Washington","otherGeospatial":"John Day Dam and McNary Dam","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.49093627929689,\n              45.72631510756141\n            ],\n            [\n              -121.5087890625,\n              45.71001523943372\n            ],\n            [\n              -121.47033691406249,\n              45.691792112909965\n            ],\n            [\n              -121.38931274414062,\n              45.67260345778067\n            ],\n            [\n              -121.34811401367186,\n              45.68603620740324\n            ],\n            [\n              -121.23825073242186,\n              45.66108710567762\n            ],\n            [\n              -121.20803833007811,\n              45.60635207711834\n            ],\n            [\n              -121.12564086914062,\n              45.59482210127054\n            ],\n            [\n              -121.06796264648436,\n              45.63516665067313\n            ],\n            [\n              -120.89492797851561,\n              45.630365250117606\n            ],\n            [\n              -120.80978393554688,\n              45.663006662228675\n            ],\n            [\n              -120.83038330078125,\n              45.68891423419542\n            ],\n            [\n              -120.88256835937499,\n              45.66684557788979\n            ],\n            [\n              -120.97595214843749,\n              45.663006662228675\n            ],\n            [\n              -121.07070922851564,\n              45.670684230297006\n            ],\n            [\n              -121.13525390625,\n              45.63132556313632\n            ],\n            [\n              -121.17233276367188,\n              45.63324613981234\n            ],\n            [\n              -121.23138427734375,\n              45.68891423419542\n            ],\n            [\n              -121.30828857421875,\n              45.70809729528788\n            ],\n            [\n              -121.40029907226562,\n              45.719603972998634\n            ],\n            [\n              -121.47033691406249,\n              45.719603972998634\n            ],\n            [\n              -121.49093627929689,\n              45.72631510756141\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"26","issue":"4","noUsgsAuthors":false,"publicationDate":"2006-11-01","publicationStatus":"PW","scienceBaseUri":"505a818de4b0c8380cd7b5b4","contributors":{"authors":[{"text":"Tiffan, K.F.","contributorId":19327,"corporation":false,"usgs":true,"family":"Tiffan","given":"K.F.","email":"","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":false,"id":419549,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Garland, R.D.","contributorId":60806,"corporation":false,"usgs":true,"family":"Garland","given":"R.D.","email":"","affiliations":[],"preferred":false,"id":419550,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rondorf, D.W.","contributorId":80789,"corporation":false,"usgs":true,"family":"Rondorf","given":"D.W.","email":"","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":false,"id":419551,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although floral biology and seed production of Joshua tree and other yuccas are well understood, the fate of Joshua tree seeds has never been studied. We tested the hypothesis that Joshua tree seeds are dispersed by seed-caching rodents. We radioactively labelled Joshua tree seeds and followed their fates at five source plants in Potosi Wash, Clark County, Nevada, USA. Rodents made a mean of 30.6 caches, usually within 30 m of the base of source plants. Caches contained a mean of 5.2 seeds buried 3-30 nun deep. A variety of rodent species appears to have prepared the caches. Three of the 836 Joshua tree seeds (0.4%) cached germinated the following spring. Seed germination using rodent exclosures was nearly 15%. More than 82% of seeds in open plots were removed by granivores, and neither microsite nor supplemental water significantly affected germination. Joshua tree produces seeds in indehiscent pods or capsules, which rodents dismantle to harvest seeds. Because there is no other known means of seed dispersal, it is possible that the Joshua tree-rodent seed dispersal interaction is an obligate mutualism for the plant.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecoscience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2980/1195-6860(2006)13[539:JTYBSA]2.0.CO;2","issn":"11956860","usgsCitation":"Vander Wall, S., Esque, T., Haines, D., Garnett, M., and Waitman, B., 2006, Joshua tree (Yucca brevifolia) seeds are dispersed by seed-caching rodents: Écoscience, v. 13, no. 4, p. 539-543, https://doi.org/10.2980/1195-6860(2006)13[539:JTYBSA]2.0.CO;2.","startPage":"539","endPage":"543","numberOfPages":"5","costCenters":[],"links":[{"id":209814,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2980/1195-6860(2006)13[539:JTYBSA]2.0.CO;2"},{"id":236537,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a400de4b0c8380cd64a23","contributors":{"authors":[{"text":"Vander Wall, S.B.","contributorId":92475,"corporation":false,"usgs":false,"family":"Vander Wall","given":"S.B.","email":"","affiliations":[{"id":16686,"text":"University of Nevada, Reno","active":true,"usgs":false}],"preferred":false,"id":418982,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Esque, T.","contributorId":19893,"corporation":false,"usgs":true,"family":"Esque","given":"T.","affiliations":[],"preferred":false,"id":418978,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Haines, D.","contributorId":30424,"corporation":false,"usgs":true,"family":"Haines","given":"D.","email":"","affiliations":[],"preferred":false,"id":418979,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garnett, M.","contributorId":36737,"corporation":false,"usgs":true,"family":"Garnett","given":"M.","email":"","affiliations":[],"preferred":false,"id":418980,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Waitman, B.A.","contributorId":70908,"corporation":false,"usgs":false,"family":"Waitman","given":"B.A.","email":"","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":418981,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

To address the undiscovered resource base in the Great Basin, a new and relatively quantitative methodology is presented. The methodology involves three steps, the first being the construction of a data-driven probabilistic model of the location of known geothermal systems using weights of evidence. The second step is the construction of a degree-of-exploration model. This degree-of-exploration model uses expert judgment in a fuzzy logic context to estimate how well each spot in the state has been explored, using as constraints digital maps of the depth to the water table, presence of the carbonate aquifer, and the location, depth, and type of drill-holes. Finally, the exploration model and the data-driven occurrence model are combined together quantitatively using area-weighted modifications to the weights-of-evidence equations. Using this methodology in the state of Nevada, the number of undiscovered geothermal systems with reservoir temperatures ???100??C is estimated at 157, which is 3.2 times greater than the 69 known systems. Currently, nine of the 69 known systems are producing electricity. If it is conservatively assumed that an additional nine for a total of 18 of the known systems will eventually produce electricity, then the model predicts 59 known and undiscovered geothermal systems are capable of producing electricity under current economic conditions in the state, a figure that is more than six times higher than the current number. Many additional geothermal systems could potentially become economic under improved economic conditions or with improved methods of reservoir stimulation (Enhanced Geothermal Systems).This large predicted geothermal resource base appears corroborated by recent grass-roots geothermal discoveries in the state of Nevada. At least two and possibly three newly recognized geothermal systems with estimated reservoir temperatures ???150??C have been identified on the Pyramid Lake Paiute Reservation in west-central Nevada. Evidence of three blind geothermal systems has recently been uncovered near the borate-bearing playas at Rhodes, Teels, and Columbus Marshes in southwestern Nevada. Recent gold exploration drilling has resulted in at least four new geothermal discoveries, including the McGinness Hills geothermal system with an estimated reservoir temperature of roughly 200??C. All of this evidence suggests that the potential for expansion of geothermal power production in Nevada is significant.","largerWorkTitle":"Transactions - Geothermal Resources Council","conferenceTitle":"GRC 2006 Annual Meeting: Geothermal Resources-Securing Our Energy Future","conferenceDate":"10 September 2006 through 13 September 2006","conferenceLocation":"San Diego, CA","language":"English","issn":"01935933","isbn":"1604230010; 9781604230017","usgsCitation":"Coolbaugh, M., Raines, G.L., Zehner, R.E., Shevenell, L., and Williams, C., 2006, Prediction and discovery of new geothermal resources in the Great Basin: Multiple evidence of a large undiscovered resource base, <i>in</i> Transactions - Geothermal Resources Council, v. 30 II, San Diego, CA, 10 September 2006 through 13 September 2006, p. 867-873.","startPage":"867","endPage":"873","numberOfPages":"7","costCenters":[],"links":[{"id":236539,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30 II","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a81e6e4b0c8380cd7b7b3","contributors":{"authors":[{"text":"Coolbaugh, M.F.","contributorId":55034,"corporation":false,"usgs":true,"family":"Coolbaugh","given":"M.F.","affiliations":[],"preferred":false,"id":419170,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Raines, G.

Within occupied wetlands, shoreline microhabitat where nests occurred was best distinguished from available, unoccupied shoreline microhabitat by steeper shore, greater near-shore and basin water depth, deeper nesting vegetation, presence of moss spp. and winterberry (Ilex verticillata), and a negative association with S. alba, leatherleaf (Chamaedaphne calyculata), and K. angustifolia.

Past attempts at integration have often focused at relatively small scales and on mechanistic models that may not capture the complexity of natural systems leaving substantial uncertainty about ecological responses to management actions. Two solutions have been proposed to guide management in the face of that uncertainty: the use of “natural variability” in key environmental patterns, processes, or disturbance as a reference; and the retention of some areas as essentially unmanaged reserves to conserve and represent as much biological diversity as possible. Both concepts are scale dependent because dominant processes or patterns that might be referenced will change with scale. Context and linkages across scales may be as important in structuring biological systems as conditions within habitats used by individual organisms. Both ideas view the physical environment as a template for expression, maintenance, and evolution of ecological diversity. To conserve or restore a diverse physical template it will be important to recognize the ecologically important differences in physical characteristics and processes among streams or watersheds that we might attempt to mimic in management or represent in conservation or restoration reserves.</p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/15715124.2006.9635279","usgsCitation":"Rieman, B., Dunham, J.B., and Clayton, J., 2006, Emerging concepts for management of river ecosystems and challenges to applied integration of physical and biological sciences in the Pacific Northwest, USA: International Journal of River Basin Management, v. 4, no. 2, p. 85-97, https://doi.org/10.1080/15715124.2006.9635279.","productDescription":"13 p.","startPage":"85","endPage":"97","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":349083,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a61142de4b06e28e9c2587c","contributors":{"authors":[{"text":"Rieman, Bruce","contributorId":101140,"corporation":false,"usgs":true,"family":"Rieman","given":"Bruce","affiliations":[],"preferred":false,"id":722719,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dunham, Jason B. 0000-0002-6268-0633 jdunham@usgs.gov","orcid":"https://orcid.org/0000-0002-6268-0633","contributorId":147808,"corporation":false,"usgs":true,"family":"Dunham","given":"Jason","email":"jdunham@usgs.gov","middleInitial":"B.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":365,"text":"Leetown Science Center","active":true,"usgs":true},{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":true,"id":722720,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Clayton, James","contributorId":92879,"corporation":false,"usgs":false,"family":"Clayton","given":"James","email":"","affiliations":[],"preferred":false,"id":722721,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

As the lake fills, survey targets on the surface of the 'ice dam' (the glacier adjacent to the lake) move obliquely to the ice margin and rise substantially. As the lake drains, ice motion speeds up, becomes nearly perpendicular to the face of the ice dam, and the ice surface drops. Vertical movement of the ice dam probably reflects growth and decay of a wedge of water beneath the ice dam, in line with established ideas about jo??kulhlaup mechanics. However, the distribution of vertical ice movement, with a narrow (50-100 m wide) zone where the uplift rate decreases by 90%, cannot be explained by invoking flexure of the ice dam in a fashion analogous to tidal flexure of a floating glacier tongue or ice shelf. Rather, the zone of large uplift-rate gradient is a fault zone: ice-dam deformation is dominated by movement along high-angle faults that cut the ice dam through its entire thickness, with the sense of fault slip reversing as the lake drains. Survey targets spanning the zone of steep uplift gradient move relative to one another in a nearly reversible fashion as the lake fills and drains. The horizontal strain rate also undergoes a reversal across this zone, being compressional as the lake fills, but extensional as the lake drains. Frictional resistance to fault-block motion probably accounts for the fact that lake level falls measurably before the onset of accelerated horizontal motion and vertical downdrop. As the overall fault pattern is the same from year to year, even though ice is lost by calving, the faults must be regularly regenerated, probably by linkage of surface and bottom crevasses as ice is advected toward the lake basin.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Glaciology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00221430","usgsCitation":"Walder, J.S., Trabant, D., Cunico, M., Fountain, A.G., Anderson, S., Anderson, R., and Malm, A., 2006, Local response of a glacier to annual filling and drainage of an ice-marginal lake: Journal of Glaciology, v. 52, no. 178, p. 440-450.","startPage":"440","endPage":"450","numberOfPages":"11","costCenters":[],"links":[{"id":237885,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"178","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a48e2e4b0c8380cd681c9","contributors":{"authors":[{"text":"Walder, J.

Evidence suggests that Great Lakes air and water temperatures have risen and the duration of ice cover has lessened during the past century. Global circulation models (GCMs) suggest future warming and increases in precipitation in the region. We present new evidence that water temperatures have risen in Lake Erie, particularly during summer and winter in the period 1965–2000. GCM forecasts coupled with physical models suggest lower annual runoff, less ice cover, and lower lake levels in the future, but the certainty of these forecasts is low. Assessment of the likely effects of climate change on fish stocks will require an integrative approach that considers several components of habitat rather than water temperature alone. We recommend using mechanistic models that couple habitat conditions to population demographics to explore integrated effects of climate-caused habitat change and illustrate this approach with a model for Lake Erie walleye (</span><i>Sander vitreum</i><span>). We show that the combined effect on walleye populations of plausible changes in temperature, river hydrology, lake levels, and light penetration can be quite different from that which would be expected based on consideration of only a single factor.</span></p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/f05-239","usgsCitation":"Jones, M., Shuter, B.J., Zhao, Y., and Stockwell, J.D., 2006, Forecasting effects of climate change on Great Lakes fisheries: models that link habitat supply to population dynamics can help: Canadian Journal of Fisheries and Aquatic Sciences, v. 63, no. 2, p. 457-468, https://doi.org/10.1139/f05-239.","productDescription":"12 p.","startPage":"457","endPage":"468","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133279,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"63","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae519","contributors":{"authors":[{"text":"Jones, Michael L.","contributorId":7219,"corporation":false,"usgs":false,"family":"Jones","given":"Michael L.","affiliations":[{"id":6590,"text":"Department of Fisheries and Wildlife, Michigan State University","active":true,"usgs":false}],"preferred":false,"id":310364,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shuter, Brian J.","contributorId":29372,"corporation":false,"usgs":true,"family":"Shuter","given":"Brian","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":310365,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zhao, Yingming","contributorId":49752,"corporation":false,"usgs":true,"family":"Zhao","given":"Yingming","affiliations":[],"preferred":false,"id":310366,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stockwell, Jason D. 0000-0003-3393-6799","orcid":"https://orcid.org/0000-0003-3393-6799","contributorId":61004,"corporation":false,"usgs":false,"family":"Stockwell","given":"Jason","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":310367,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Interpretation of age from environmental tracer data may be relatively simple for a water sample with a single age, but the interpretation is more complex for a sample that is a mixture of waters of varying ages. A mixture can be a natural result of convergence of flow lines to a discharge area such as a spring or stream, or it can be an artefact of sampling a long-screen well. TRACERMODEL1 contains a worksheet that can be used to determine hypothetical concentrations of atmospheric environmental tracers in water samples with several different age distributions. It is designed to permit plotting of ages and tracer concentrations in a variety of different combinations to facilitate interpretation of measurements. TRACERMODEL1 includes several different types of graphs that are linked to the calculations. The spreadsheet and accompanying graphs can be modified for specific applications. For example, the selection of atmospheric environmental tracers can be changed to reflect analytes of interest, the input tracer data can be modified to reflect local conditions or different timescales, and the analytes of interest can include other types of non-point-source contaminants, such as nitrate (Böhlke, 2002).

These data complement long-term, high-resolution tide, wave, current, temperature, salinity and turbidity measurements made at a number of fixed locations in the study area starting in 2001. Analyses of these hydrographic data, in conjunction with numerous field observations, evoke the following conceptual model of water and turbidity flux along West Maui. Wave- and wind-driven flows appear to be the primary control on flow over shallower portions of the reefs while tidal and subtidal currents dominate flow over the outer portions of the reefs and insular shelf. When the direction of these flows counter one another, which is quite common, they cause a zone of cross-shore horizontal shear and often form a front, with turbid, lower-salinity water inshore of the front and clear, higher-salinity water offshore of the front. It is not clear whether these zones of high shear and fronts are the cause or the result of the location of the fore reef, but they appear to be correlated alongshore over relatively large horizontal distances (orders of kilometers). When two flows converge or when a single flow is bathymetrically steered, eddies can be generated that, in the absence of large ocean surface waves, tend to accumulate material. Areas of higher turbidity and lower salinity tend to correlate with regions of poor coral health or the absence of well-developed reefs, suggesting that the oceanographic processes that concentrate and/or transport nutrients, contaminants, low-salinity water or suspended sediment might strongly influence coral reef ecosystem health and sustainability.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Continental Shelf Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.csr.2005.12.006","issn":"02784343","usgsCitation":"Storlazzi, C., McManus, M., Logan, J., and McLaughlin, B., 2006, Cross-shore velocity shear, eddies and heterogeneity in water column properties over fringing coral reefs: West Maui, Hawaii: Continental Shelf Research, v. 26, no. 3, p. 401-421, https://doi.org/10.1016/j.csr.2005.12.006.","startPage":"401","endPage":"421","numberOfPages":"21","costCenters":[],"links":[{"id":212027,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.csr.2005.12.006"},{"id":239430,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fcc6e4b0c8380cd4e41d","contributors":{"authors":[{"text":"Storlazzi, C.

Under certain hydrogeological conditions such aquifers can function as giant natural weighing lysimeters, referenced here as 'geological weighing lysimeters'. The extent of the land area 'weighed' increases with aquifer depth and it is of interest to establish at what depth it is still possible to monitor surface water budgets. An 86 mm rainfall event produced a clear loading signal in a well in western Kansas at 300 m depth. The loading effect is quantitatively consistent with elastic deformation induced by the rainfall mass and suggests that geological weighing lysimeters could operate at considerably greater depths, thereby monitoring water budgets over a significant land area. ?? 2005 Elsevier Ltd All rights reserved.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2005.06.031","issn":"00221694","usgsCitation":"Sophocleous, M., Bardsley, E., and Healey, J., 2006, A rainfall loading response recorded at 300 meters depth: Implications for geological weighing lysimeters: Journal of Hydrology, v. 319, no. 1-4, p. 237-244, https://doi.org/10.1016/j.jhydrol.2005.06.031.","startPage":"237","endPage":"244","numberOfPages":"8","costCenters":[],"links":[{"id":477707,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/10289/3932","text":"External Repository"},{"id":238886,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211578,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2005.06.031"}],"volume":"319","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e529e4b0c8380cd46b8a","contributors":{"authors":[{"text":"Sophocleous, M.","contributorId":13373,"corporation":false,"usgs":true,"family":"Sophocleous","given":"M.","email":"","affiliations":[],"preferred":false,"id":428489,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bardsley, E.","contributorId":26875,"corporation":false,"usgs":true,"family":"Bardsley","given":"E.","email":"","affiliations":[],"preferred":false,"id":428490,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Healey, J.","contributorId":60852,"corporation":false,"usgs":true,"family":"Healey","given":"J.","email":"","affiliations":[],"preferred":false,"id":428491,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Conductivity profiles from Berg Lake, perched 135 m a.s.l., show no salt in the lake, but the temperature profiles indicate an apparently unstable situation, the 4??C density maximum is located at 10 m depth, not at the bottom of the lake (90 m depth). Subglacial discharge from the Steller Glacier into the bottom of the lake must inject a suspended sediment load sufficient to marginally stabilize the water column throughout the lake. In Vitus Lake, terminus positions derived from satellite imagery show that the glacier terminus rapidly retreated from 1995 to the present resulting in a substantial expansion of the volume of Vitus Lake. Conductivity and temperature profiles from the tidally influenced Vitus Lake show a complex four-layer system with diluted (???50%) seawater in the bottom of the lake. This lake has a complex vertical structure that is the result of convection generated by ice melting in salt water, stratification within the lake, and freshwater entering the lake from beneath the glacier and surface runoff. Four consecutive years, from 2001 to 2004, of these observations in Vitus Lake show little change in the deep temperature and salinity conditions, indicating limited deep water renewal. The combination of the lake level measurements with discharge measurements, through a tidal cycle, by an acoustic Doppler Current Profiler (ADCP) deployed in the Seal River, which drains the entire Bering system, showed a strong tidal influence but no seawater entry into Vitus Lake. The ADCP measurements combined with lake level measurements established a relationship between lake level and discharge, which when integrated over a tidal cycle, gives a tidally averaged discharge ranging from 1310 to 1510 m3 s-1. ?? 2006 Regents of the University of Colorado.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Arctic, Antarctic, and Alpine Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1657/1523-0430(2006)38[547:HACOIL]2.0.CO;2","issn":"15230430","usgsCitation":"Josberger, E., Shuchman, R., Meadows, G., Savage, S., and Payne, J., 2006, Hydrography and circulation of ice-marginal lakes at Bering Glacier, Alaska, U.S.A.: Arctic, Antarctic, and Alpine Research, v. 38, no. 4, p. 547-560, https://doi.org/10.1657/1523-0430(2006)38[547:HACOIL]2.0.CO;2.","startPage":"547","endPage":"560","numberOfPages":"14","costCenters":[],"links":[{"id":477604,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://www.bioone.org/doi/10.1657/1523-0430%282006%2938%5B547%3AHACOIL%5D2.0.CO%3B2","text":"External Repository"},{"id":209795,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1657/1523-0430(2006)38[547:HACOIL]2.0.CO;2"},{"id":236512,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"38","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3501e4b0c8380cd5fbd2","contributors":{"authors":[{"text":"Josberger, E.G.","contributorId":61161,"corporation":false,"usgs":true,"family":"Josberger","given":"E.G.","email":"","affiliations":[],"preferred":false,"id":419591,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shuchman, R.A.","contributorId":27204,"corporation":false,"usgs":true,"family":"Shuchman","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":419589,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Meadows, G.A.","contributorId":82994,"corporation":false,"usgs":true,"family":"Meadows","given":"G.A.","email":"","affiliations":[],"preferred":false,"id":419592,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Savage, S.","contributorId":103049,"corporation":false,"usgs":true,"family":"Savage","given":"S.","email":"","affiliations":[],"preferred":false,"id":419593,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Payne, J.","contributorId":37126,"corporation":false,"usgs":true,"family":"Payne","given":"J.","affiliations":[],"preferred":false,"id":419590,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Although artificially cultured juveniles have been produced and released to the wild at various times of the year, no study has investigated the best time of year to release these juveniles. Newly metamorphosed juveniles of the wavyrayed lampmussel (Lampsilis fasciola) were released into a stream-fed fish hatchery raceway during March, June, and September. Growth and survival rates were measured 32, 52, 72, and 92 days post-metamorphosis. Juveniles released in June experienced the greatest growth and survival rates. Juveniles released in September and March experienced high mortality within the first month of release and exhibited poor growth in the cool water conditions typical of those seasons. Overwinter survival exhibited a size-dependent relationship.","language":"English","publisher":"American Malacological Society","issn":"07402783","usgsCitation":"Hanlon, S.D., and Neves, R.J., 2006, Seasonal growth and mortality of juveniles of <i>Lampsilis fasciola</i> (Bivalvia: Unionidae) released to a fish hatchery raceway: American Malacological Bulletin, v. 21, no. 1-2, p. 45-49.","productDescription":"5 p.","startPage":"45","endPage":"49","costCenters":[],"links":[{"id":238750,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":341045,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.biodiversitylibrary.org/item/173697#page/49/mode/1up"}],"volume":"21","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b88abe4b08c986b316ac3","contributors":{"authors":[{"text":"Hanlon, Shane D.","contributorId":172762,"corporation":false,"usgs":false,"family":"Hanlon","given":"Shane","email":"","middleInitial":"D.","affiliations":[{"id":12428,"text":"U.

Fish barrier technology is being studied to stop the spread of invasive fish species such as ruffe. Electrical barriers have been constructed, most notably in the Chicago Sanitary and Ship Canal, to prevent non-indigenous species such as ruffe from spreading into areas where they are currently absent. Information on the response of an invasive fish to barriers can help managers determine strategies to prevent the spread of these species via artificial waterways. In this laboratory study electrical barriers were set up to determine effectiveness of four electrical settings for repelling Eurasian ruffe measuring 10 cm or more in length. In separate tests, airbubble curtains with two bubble sizes and densities were created to test this type of barrier in blocking movement of ruffe less than 10 cm in length. The most effective electrical settings found (5 ms, 6 Hz) repelled only about half of the attempted passes. When ruffe were offered food or shelter on the opposite side of the electrical barrier, neither food-starved nor shelter-deprived ruffe made significantly more attempts to cross the barrier. Ruffe were significantly repelled by all air-bubble curtains, but a large proportion of passes (4.5 passes per fish on average in the treatments) were still observed. Electrical barrier settings and air-bubble curtains used in this study were found ineffective at completely blocking the movement, but somewhat effective at inhibiting the passage of ruffe.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Dawson, H.A., Reinhardt, U.G., and Savino, J.F., 2006, Use of electric and bubble barriers to limit the movement of Eurasian ruffe (Gymnocephalus cernuus): Journal of Great Lakes Research, v. 32, no. 1, p. 40-49.","productDescription":"p. 40-49","startPage":"40","endPage":"49","numberOfPages":"9","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":128564,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a17e4b07f02db604610","contributors":{"authors":[{"text":"Dawson, Heather A.","contributorId":12409,"corporation":false,"usgs":true,"family":"Dawson","given":"Heather","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":310387,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reinhardt, Ulrich G.","contributorId":46040,"corporation":false,"usgs":true,"family":"Reinhardt","given":"Ulrich","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":310388,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Savino, Jacqueline F. jsavino@usgs.gov","contributorId":2213,"corporation":false,"usgs":true,"family":"Savino","given":"Jacqueline","email":"jsavino@usgs.gov","middleInitial":"F.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":310386,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These four sites were surveyed again in 1998 using the same sampling method (timed-random searches) to determine if they may serve as “refugia” where unionids and dreissenids co-exist. Two additional sites were sampled using additional methods (excavated-quadrat and line-transect searches) for comparison with unpublished data collected in 1987 and 1990. A total of four individuals of four species (</span><i><span class=\"genus-species\">Actinonaias ligamentina</span></i><span>,&nbsp;</span><i><span class=\"genus-species\">Cyclonaias tuberculata</span></i><span>,&nbsp;</span><i><span class=\"genus-species\">Lasmigona complanata</span></i><span>&nbsp;and&nbsp;</span><i><span class=\"genus-species\">Pleurobema sintoxia</span></i><span>) were found by timed-random searches at four sites in 1998 compared to 720 individuals of 24 species in 1992 and 39 individuals of 13 species in 1994.

Results of this study suggest that remaining densities of unionids in channels of the Detroit River are too low to support viable reproducing populations of any species. Therefore, we conclude that unionids have been extirpated from main channels of the Detroit River due to dreissenid infestation. As the Detroit River was one of the first water bodies in North America to be invaded by dreissenids, it is likely that unionids will also be extirpated from many other rivers and lakes across eastern North America over the next few decades. Resource agencies should be encouraged to implement active management programs to protect remaining unionid populations from zebra mussels.</span></p>","language":"English","publisher":"University of Notre Dame","doi":"10.1674/0003-0031(2006)155[307:EOFMBU]2.0.CO;2","usgsCitation":"Schloesser, D.W., Metcalfe-Smith, J.L., Kovalak, W.P., Longton, G.D., and Smithee, R.D., 2006, Extirpation of freshwater mussels (Bivalvia: Unionidae) following the invasion of dreissenid mussels in an interconnecting river of the Laurentian Great Lakes: American Midland Naturalist, v. 155, no. 2, p. 307-320, https://doi.org/10.1674/0003-0031(2006)155[307:EOFMBU]2.0.CO;2.","productDescription":"14 p.","startPage":"307","endPage":"320","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":412910,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United  States","state":"Michigan","otherGeospatial":"Detroit River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -82.93917557144205,\n              42.36486265488605\n            ],\n            [\n              -83.02386372199643,\n              42.36486265488605\n            ],\n            [\n              -83.02386372199643,\n              42.321294249119575\n            ],\n            [\n              -82.93917557144205,\n              42.321294249119575\n            ],\n            [\n              -82.93917557144205,\n              42.36486265488605\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"155","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db688361","contributors":{"authors":[{"text":"Schloesser, Don W.","contributorId":21485,"corporation":false,"usgs":true,"family":"Schloesser","given":"Don","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":310441,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Metcalfe-Smith, Janice L.","contributorId":82267,"corporation":false,"usgs":true,"family":"Metcalfe-Smith","given":"Janice","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":310443,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kovalak, William P.","contributorId":77479,"corporation":false,"usgs":true,"family":"Kovalak","given":"William","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":310442,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Longton, Gary D.","contributorId":17199,"corporation":false,"usgs":true,"family":"Longton","given":"Gary","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":310440,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Smithee, Rick D.","contributorId":100807,"corporation":false,"usgs":true,"family":"Smithee","given":"Rick","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":310444,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
