We used 18 years of color-banding data and multistate capture-recapture models to test whether habitat quality within territories influences survival and detection probability of breeding Florida Scrub-Jays (Aphelocoma coerulescens) and to estimate bird transition probabilities from one territory quality state to another. Our study sites were along central Florida's Atlantic coast and included two of the four largest metapopulations within the species range. We developed Markov models for habitat transitions and compared these to bird transition probabilities. Florida Scrub-Jay detection probabilities ranged from 0.88 in the tall territory state to 0.99 in the optimal state; detection probabilities were intermediate in the short state. Transition probabilities were similar for birds and habitat in grid cells mapped independently of birds. Thus, bird transitions resulted primarily from habitat transitions between states over time and not from bird movement. Survival ranged from 0.71 in the short state to 0.82 in the optimal state, with tall states being intermediate. We conclude that average Florida Scrub-Jay survival will remain at levels that lead to continued population declines because most current habitat quality is only marginally suitable across most of the species range. Improvements in habitat are likely to be slow and difficult because tall states are resistant to change and the optimal state represents an intermediate transitional stage. The multistate modeling approach to quantifying survival and habitat transition probabilities is useful for quantifying habitat transition probabilities and comparing them to bird transition probabilities to test for habitat selection in dynamic environments. ?? 2009 by the Ecological society ot America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-1123.1","issn":"00129658","usgsCitation":"Breininger, D., Nichols, J., Carter, G., and Oddy, D., 2009, Habitat-specific breeder survival of Florida Scrub-Jays: Inferences from multistate models: Ecology, v. 90, no. 11, p. 3180-3189, https://doi.org/10.1890/08-1123.1.","startPage":"3180","endPage":"3189","numberOfPages":"10","costCenters":[],"links":[{"id":501653,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://stars.library.ucf.edu/facultybib2000/7048","text":"External Repository"},{"id":216188,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-1123.1"},{"id":244041,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"90","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f4ce4b0c8380cd5cc75","contributors":{"authors":[{"text":"Breininger, D.R.","contributorId":62856,"corporation":false,"usgs":true,"family":"Breininger","given":"D.R.","affiliations":[],"preferred":false,"id":451561,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":451558,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carter, G.M.","contributorId":54429,"corporation":false,"usgs":true,"family":"Carter","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":451560,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Oddy, D.M.","contributorId":30845,"corporation":false,"usgs":true,"family":"Oddy","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":451559,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Our shear-wave reflection section helps us identify and map an important and previously unknown flow barrier at depth; it also helps us map other relevant structure within the surficial aquifer. Development of an accurate velocity model is essential for depth conversion and interpretation of the reflection section. We incorporate information provided by shear-wave seismic methods along with cone penetrometer testing and seismic cone penetrometer testing measurements. One velocity model is based on reflected and refracted arrivals and provides reliable velocity estimates for the full depth range of interest when anchored on interface depths determined from cone data and borehole drillers' logs. A second velocity model is based on seismic cone penetrometer testing data that provide higher-resolution ID velocity columns with error estimates within the depth range of the cone penetrometer testing. Comparison of the reflection/refraction model with the seismic cone penetrometer testing model also suggests that the mass of the cone truck can influence velocity with the equivalent effect of approximately one metre of extra overburden stress. Together, these velocity models and the depth-converted reflection section result in a better constrained hydrologic model of the subsurface and illustrate the pivotal role that cone data can provide in the reflection processing workflow. ?? 2009 European Association of Geoscientists & Engineers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Near Surface Geophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"15694445","usgsCitation":"Haines, S., Pidlisecky, A., and Knight, R., 2009, Hydrogeologic structure underlying a recharge pond delineated with shear-wave seismic reflection and cone penetrometer data: Near Surface Geophysics, v. 7, no. 5-6, p. 329-339.","startPage":"329","endPage":"339","numberOfPages":"11","costCenters":[],"links":[{"id":244321,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"5-6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3403e4b0c8380cd5f427","contributors":{"authors":[{"text":"Haines, S.S. 0000-0003-2611-8165","orcid":"https://orcid.org/0000-0003-2611-8165","contributorId":33402,"corporation":false,"usgs":true,"family":"Haines","given":"S.S.","affiliations":[],"preferred":false,"id":451182,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pidlisecky, Adam","contributorId":94877,"corporation":false,"usgs":true,"family":"Pidlisecky","given":"Adam","email":"","affiliations":[],"preferred":false,"id":451183,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knight, R.","contributorId":22717,"corporation":false,"usgs":true,"family":"Knight","given":"R.","affiliations":[],"preferred":false,"id":451181,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Watershed management has evolved from fl oodplain drainage via pervasive channelization to include local drainage canal maintenance and local river restoration. Many unmaintained canals are undergoing excessive aggradation and complex channel evolution driven by upland erosion and low valley gradient. The locus of aggradation in fully occluded canals (valley plugs) moves up-valley as sediment continues to accumulate in the backwater behind the plug. Valley plugs that cause canal avulsion can lead to redevelopment of meandering channels in less disturbed areas of the fl oodplain, in a process of passive self-restoration. Some valley plugs have brought restored fl oodplain function, reoccupation of extant historic river channels, and formation of a \"sediment shadow\" that protects downstream reaches from excess sedimentation. Despite the presence of numerous opportunities, there is presently no mechanism for including valley plugs in mitigation projects. In 1997 a survey of 14 reference reach cross sections documented relations between drainage area and bankfull geometry of relatively unmodified streams in West Tennessee. Reassessment of seven of those sites in 2007 showed that one had been dammed by beaver and that two sites could not be analyzed further because of signifi cant vertical or lateral instability. In contrast to other regions of North America, the results suggest that stream channels in this region fl ood more frequently than once each year, and can remain out of banks for several weeks each year. ?? 2009 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/2009.2451(14)","issn":"00721077","usgsCitation":"Smith, D., Diehl, T., Turrini-Smith, L.A., Maas-Baldwin, J., and Croyle, Z., 2009, River restoration strategies in channelized, low-gradient landscapes of West Tennessee, USA: Special Paper of the Geological Society of America, no. 451, p. 215-229, https://doi.org/10.1130/2009.2451(14).","startPage":"215","endPage":"229","numberOfPages":"15","costCenters":[],"links":[{"id":216299,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/2009.2451(14)"},{"id":244162,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"451","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aadb6e4b0c8380cd86f66","contributors":{"authors":[{"text":"Smith, D.P.","contributorId":64911,"corporation":false,"usgs":true,"family":"Smith","given":"D.P.","email":"","affiliations":[],"preferred":false,"id":451137,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Diehl, T.H.","contributorId":89170,"corporation":false,"usgs":true,"family":"Diehl","given":"T.H.","email":"","affiliations":[],"preferred":false,"id":451140,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Turrini-Smith, L.

Adaptation of farming practices to mitigate adverse impacts of climate change on wetland water levels is a potential watershed management option. We chose a modeling approach (WETSIM 3.2) to examine the effects of changes in climate and watershed cover on the water levels of a semi-permanent wetland in eastern South Dakota. Land-use practices simulated were unmanaged grassland, grassland managed with moderately heavy grazing, and cultivated crops. Climate scenarios were developed by adjusting the historical climate in combinations of 2??C and 4??C air temperature and ??10% precipitation. For these climate change scenarios, simulations of land use that produced water levels equal to or greater than unmanaged grassland under historical climate were judged to have mitigative potential against a drier climate. Water levels in wetlands surrounded by managed grasslands were significantly greater than those surrounded by unmanaged grassland. Management reduced both the proportion of years the wetland went dry and the frequency of dry periods, producing the most dynamic vegetation cycle for this modeled wetland. Both cultivated crops and managed grassland achieved water levels that were equal or greater than unmanaged grassland under historical climate for the 2??C rise in air temperature, and the 2??C rise plus 10% increase in precipitation scenarios. Managed grassland also produced water levels that were equal or greater than unmanaged grassland under historical climate for the 4??C rise plus 10% increase in precipitation scenario. Although these modeling results stand as hypotheses, they indicate that amelioration potential exists for a change in climate up to an increase of 2??C or 4??C with a concomitant 10% increase in precipitation. Few empirical data exist to verify the results of such land-use simulations; however, adaptation of farming practices is one possible mitigation avenue available for prairie wetlands. ?? 2009, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/07-241.1","issn":"02775212","usgsCitation":"Voldseth, R., Johnson, W., Guntenspergen, G., Gilmanov, T., and Millett, B., 2009, Adaptation of farming practices could buffer effects of climate change on northern prairie wetlands: Wetlands, v. 29, no. 2, p. 635-647, https://doi.org/10.1672/07-241.1.","startPage":"635","endPage":"647","numberOfPages":"13","costCenters":[],"links":[{"id":216268,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/07-241.1"},{"id":244131,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e6e0e4b0c8380cd476c1","contributors":{"authors":[{"text":"Voldseth, R.A.","contributorId":80778,"corporation":false,"usgs":true,"family":"Voldseth","given":"R.A.","affiliations":[],"preferred":false,"id":451134,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, W.C.","contributorId":68003,"corporation":false,"usgs":true,"family":"Johnson","given":"W.C.","email":"","affiliations":[],"preferred":false,"id":451132,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guntenspergen, G.R. 0000-0002-8593-0244","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":95424,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"G.R.","affiliations":[],"preferred":false,"id":451135,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gilmanov, T.","contributorId":72892,"corporation":false,"usgs":true,"family":"Gilmanov","given":"T.","email":"","affiliations":[],"preferred":false,"id":451133,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Millett, B.V.","contributorId":48274,"corporation":false,"usgs":true,"family":"Millett","given":"B.V.","email":"","affiliations":[],"preferred":false,"id":451131,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Increased societal, industrial, and agricultural demands for water may encourage the use of alternative sources such as wastewater effluents in managed wetlands. However, water quality is commonly overlooked as an influence on wetland soil seed banks and soils. In four separate greenhouse trials conducted over a 2-yr period, we examined the effects of municipal wastewater effluent (WWE) on vegetation of wetland seed banks and soils excavated from a wildlife management area in Missouri, USA. We used microcosms filled with one of two soil materials and irrigated with WWE, Missouri River water, or deionized water to simulate moist-soil conditions. Vegetation that germinated from the soil seed bank was allowed to grow in microcosms for approximately 100 d. Vegetative taxa richness, plant density, and biomass were significantly reduced in WWE-irrigated soil materials compared with other water sources. Salinity and sodicity rapidly increased in WWE-irrigated microcosms and probably was responsible for inhibiting germination or interfering with seedling development. Our results indicate that irrigation with WWE promoted saline-sodic soil conditions, which alters the vegetation community by inhibiting germination or seedling development. ?? 2009, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/08-58.1","issn":"02775212","usgsCitation":"Finocchiaro, R., Kremer, R., and Fredrickson, L., 2009, Impact of municipal wastewater effluent on seed bank response and soils excavated from a wetland impoundment: Wetlands, v. 29, no. 2, p. 713-723, https://doi.org/10.1672/08-58.1.","startPage":"713","endPage":"723","numberOfPages":"11","costCenters":[],"links":[{"id":216449,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/08-58.1"},{"id":244319,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a38c2e4b0c8380cd616a6","contributors":{"authors":[{"text":"Finocchiaro, R.G.","contributorId":15038,"corporation":false,"usgs":true,"family":"Finocchiaro","given":"R.G.","affiliations":[],"preferred":false,"id":451034,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kremer, R.J.","contributorId":47608,"corporation":false,"usgs":true,"family":"Kremer","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":451035,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fredrickson, L.H.","contributorId":91042,"corporation":false,"usgs":true,"family":"Fredrickson","given":"L.H.","email":"","affiliations":[],"preferred":false,"id":451036,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Using multiple depth surface elevation tables (SETs) and marker horizons we measured soil accretion, erosion, and soil elevation. We partitioned the effect of Hurricane Wilma's storm deposit into four constituent soil zones: surface (accretion) zone, shallow zone (0–0.35 m), middle zone (0.35–4 m), and deep zone (4–6 m). We report expansion and contraction of each soil zone. Hurricane Wilma deposited 37.0 (± 3.0 SE) mm of material; however, the absolute soil elevation change was + 42.8 mm due to expansion in the shallow soil zone. One year post-hurricane, the soil profile had lost 10.0 mm in soil elevation, with 8.5 mm of the loss due to erosion. The remaining soil elevation loss was due to compaction from shallow subsidence. We found prolific growth of new fine rootlets (209 ± 34 SE g m<sup>−2</sup>) in the storm deposited material suggesting that deposits may become more stable in the near future (i.e., erosion rate will decrease). Surficial erosion and belowground processes both played an important role in determining the overall soil elevation. Expansion and contraction in the shallow soil zone may be due to hydrology, and in the middle and bottom soil zones due to shallow subsidence. Findings thus far indicate that soil elevation has made substantial gains compared to site specific relative sea-level rise, but data trends suggest that belowground processes, which differ by soil zone, may come to dominate the long term ecological impact of storm deposit.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Society of Wetland Scientists","doi":"10.1672/08-125.1","issn":"02775212","usgsCitation":"Whelan, K., Smith, T.J., Anderson, G., and Ouellette, M., 2009, Hurricane Wilma's impact on overall soil elevation and zones within the soil profile in a mangrove forest: Wetlands, v. 29, no. 1, p. 16-23, https://doi.org/10.1672/08-125.1.","productDescription":"8 p.","startPage":"16","endPage":"23","costCenters":[{"id":275,"text":"Florida Integrated Science Center","active":false,"usgs":true}],"links":[{"id":215373,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/08-125.1"},{"id":243171,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"Everglades National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.52,24.85 ], [ -81.52,25.89 ], [ -80.39,25.89 ], [ -80.39,24.85 ], [ -81.52,24.85 ] ] ] } } ] }","volume":"29","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a32b4e4b0c8380cd5e9fb","contributors":{"authors":[{"text":"Whelan, K.R.T.","contributorId":11311,"corporation":false,"usgs":true,"family":"Whelan","given":"K.R.T.","email":"","affiliations":[],"preferred":false,"id":450276,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, T.

The strain was isolated aerobically on R2A medium agar plates supplemented with NaCl (20 g l<sup>-1</sup>) and MgCl<sub>2</sub>???6H <sub>2</sub>O (3 g l<sup>-1</sup>). The colonies were circular, convex, smooth and orange. Cells were slightly curved, rod-shaped in young cultures and often appeared in pairs. In older cultures cells were coccoid. Cells stained Gram-positive, were non-motile and did not form endospores. The diagnostic diamino acid of the peptidoglycan was ll-diaminopimelic acid. The polar lipids included phosphatidylglycerol, diphosphatidglycerol, four different glycolipids, two further phospholipids and one unidentified lipid. The dominant menaquinone was MK-9(H<sub>4</sub>) (70%). The major cellular fatty acid was anteiso C15:0 (83%). The DNA G + C content was 68 mol%. The strain grew anaerobically by reducing nitrate to nitrite or by fermenting glucose. It was catalase positive and oxidase negative. It grew between 10 and 45??C, with an optimum between 35 and 40??C. The pH range for growth was 5.7-9.3, with an optimum at pH 7.5. The closest phylogenetic neighbors based on 16S rRNA gene sequence identity were members of the genus Tessaracoccus (95-96% identity). On the basis of phenotypic and phylogenetic distinctiveness, strain CB31<sup>T</sup> is considered to represent a novel species of the genus Tessaracoccus, for which we propose the name Tessaracoccus profundi sp. nov.. It is the first member of this genus that has been isolated from a deep subsurface environment.

For example, models of the detection process based on distance-sampling or time-of-detection methods may yield different results for auditory versus visual cues because of differences in the factors that affect the transmission of these cues from a bird to an observer or differences in an observer's ability to localize cues. Previous studies suggest that auditory detections predominate in forested habitats, but it is not clear how often observers hear birds prior to detecting them visually. We hypothesized that auditory cues might be even more important than previously reported, so we conducted an experiment in a forested habitat in North Carolina that allowed us to better separate auditory and visual detections. Three teams of three observers each performed simultaneous 3-min unlimited-radius point counts at 30 points in a mixed-hardwood forest. One team member could see, but not hear birds, one could hear, but not see, and the third was nonhandicapped. Of the total number of birds detected, 2.9% were detected by deafened observers, 75.1% by blinded observers, and 78.2% by nonhandicapped observers. Detections by blinded and nonhandicapped observers were the same only 54% of the time. Our results suggest that the detection of birds in forest habitats is almost entirely by auditory cues. Because many factors affect the probability that observers will detect auditory cues, the accuracy and precision of avian point count estimates are likely lower than assumed by most field ornithologists. ?? 2009 Association of Field Ornithologists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Field Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1557-9263.2009.00220.x","issn":"02738570","usgsCitation":"Brewster, J., and Simons, T., 2009, Testing the importance of auditory detections in avian point counts: Journal of Field Ornithology, v. 80, no. 2, p. 178-182, https://doi.org/10.1111/j.1557-9263.2009.00220.x.","startPage":"178","endPage":"182","numberOfPages":"5","costCenters":[],"links":[{"id":215387,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1557-9263.2009.00220.x"},{"id":243186,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba5d5e4b08c986b320cf1","contributors":{"authors":[{"text":"Brewster, J.P.","contributorId":38801,"corporation":false,"usgs":true,"family":"Brewster","given":"J.P.","email":"","affiliations":[],"preferred":false,"id":449049,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Simons, T.R.","contributorId":56334,"corporation":false,"usgs":true,"family":"Simons","given":"T.R.","email":"","affiliations":[],"preferred":false,"id":449050,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study relates the seed bank densities of species of Taxodium distichum swamps to local water regime and regional climate factors at five latitudes across the Mississippi River Alluvial Valley from southern Illinois to Louisiana. In an outdoor nursery setting, the seed banks of twenty-five swamps were exposed to non-flooded (freely drained) or flooded treatments, and the number and species of seeds germinating were recorded from each swamp during one growing season. Based on ANOVA analysis, the majority of dominant species had a higher rate of germination in non-flooded versus flooded treatments. Similarly, an NMS comparison, which considered the local water regime and regional climate of the swamps, found that the species of seeds germinating, almost completely shifted under non-flooded versus flooded treatments. For example, in wetter northern swamps, seeds of Taxodium distichum germinated in non-flooded conditions, but did not germinate from the same seed banks in flooded conditions. In wetter southern swamps, seeds of Eleocharis cellulosa germinated in flooded conditions, but did not germinate in non-flooded conditions. The strong relationship of seed germination and density relationships with local water regime and regional climate variables suggests that the forecasting of climate change effects on swamps and other wetlands needs to consider a variety of interrelated variables to make adequate projections of the regeneration responses of species to climate change. Because regeneration is an important aspect of species maintenance and restoration, climate drying could influence the species distribution of these swamps in the future. ?? 2008 Springer Science+Business Media B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Plant Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11258-008-9480-4","issn":"13850237","usgsCitation":"Middleton, B., 2009, Regeneration potential of Taxodium distichum swamps and climate change: Plant Ecology, v. 202, no. 2, p. 257-274, https://doi.org/10.1007/s11258-008-9480-4.","startPage":"257","endPage":"274","numberOfPages":"18","costCenters":[],"links":[{"id":215139,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11258-008-9480-4"},{"id":242917,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"202","issue":"2","noUsgsAuthors":false,"publicationDate":"2008-08-09","publicationStatus":"PW","scienceBaseUri":"50e4a457e4b0e8fec6cdbb3b","contributors":{"authors":[{"text":"Middleton, B.A. 0000-0002-1220-2326 middletonb@usgs.gov","orcid":"https://orcid.org/0000-0002-1220-2326","contributorId":89108,"corporation":false,"usgs":true,"family":"Middleton","given":"B.A.","email":"middletonb@usgs.gov","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":false,"id":448783,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We use 73 <sup>230</sup>Th dates from speleothems collected from a cave in southwestern Oregon (USA) to constrain speleothem growth for the past 380&nbsp;000&nbsp;years. Most speleothem growth occurred during interglacial periods, whereas little growth occurred during glacial intervals. To evaluate potential environmental controls on speleothem growth we use two new modeling approaches: i) a one-dimensional thermal advection&ndash;diffusion model to estimate cave temperatures during the last glacial cycle, and ii) a regional climate model simulation for the Last Glacial Maximum (21&nbsp;000&nbsp;years before present) that assesses a range of potential controls on speleothem growth under peak glacial conditions. The two models are mutually consistent in indicating that permafrost formation did not influence speleothem growth during glacial periods. Instead, the regional climate model simulation combined with proxy data suggest that the influence of the Laurentide and Cordilleran ice sheets on atmospheric circulation induced substantial changes in water balance in the Pacific Northwest and affected speleothem growth at our location. The overall drier conditions during glacial intervals and associated periods of frozen topsoil at times of maximum surface runoff likely induced drastic changes in cave recharge and limited speleothem growth. This mechanism could have affected speleothem growth in other mid-latitude caves without requiring the presence of permafrost.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.epsl.2009.01.008","issn":"0012821X","usgsCitation":"Ersek, V., Hostetler, S.W., Cheng, H., Clark, P., Anslow, F.S., Mix, A.C., and Edwards, R.L., 2009, Environmental influences on speleothem growth in southwestern Oregon during the last 380, 000 years: Earth and Planetary Science Letters, v. 279, no. 3-4, p. 316-325, https://doi.org/10.1016/j.epsl.2009.01.008.","productDescription":"10 p.","startPage":"316","endPage":"325","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":243499,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215679,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.epsl.2009.01.008"}],"country":"United States","state":"Oregon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.02636718749999,\n              42.016651835568226\n            ],\n            [\n              -116.98242187499999,\n              44.213709909702054\n            ],\n            [\n              -117.22412109375,\n              44.37098696297173\n            ],\n            [\n              -116.52099609375,\n              45.644768217751924\n            ],\n            [\n              -117.00439453125,\n              46.057985244793024\n            ],\n            [\n              -117.18017578125,\n              45.98169518512228\n            ],\n            [\n              -119.0478515625,\n              46.01222384063236\n            ],\n            [\n              -120.498046875,\n              45.75219336063106\n            ],\n            [\n              -122.58544921875,\n              45.62940492064501\n            ],\n            [\n              -122.98095703125,\n              46.11894150610708\n            ],\n            [\n              -124.03564453125,\n              46.195042108660154\n            ],\n            [\n              -124.60693359374999,\n              42.81152174509788\n            ],\n            [\n              -124.45312499999999,\n              42.56926437219384\n            ],\n            [\n              -124.43115234375,\n              42.24478535602799\n            ],\n            [\n              -124.25537109375,\n              41.96765920367816\n            ],\n            [\n              -117.02636718749999,\n              42.016651835568226\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"279","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a09d2e4b0c8380cd520a1","contributors":{"authors":[{"text":"Ersek, Vasile","contributorId":37560,"corporation":false,"usgs":true,"family":"Ersek","given":"Vasile","affiliations":[],"preferred":false,"id":448510,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hostetler, Steven W. 0000-0003-2272-8302 swhostet@usgs.gov","orcid":"https://orcid.org/0000-0003-2272-8302","contributorId":3249,"corporation":false,"usgs":true,"family":"Hostetler","given":"Steven","email":"swhostet@usgs.gov","middleInitial":"W.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":448511,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cheng, Hai","contributorId":85896,"corporation":false,"usgs":true,"family":"Cheng","given":"Hai","affiliations":[],"preferred":false,"id":448507,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Clark, Peter U.","contributorId":68994,"corporation":false,"usgs":true,"family":"Clark","given":"Peter U.","affiliations":[],"preferred":false,"id":448513,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Anslow, Faron S.","contributorId":35442,"corporation":false,"usgs":true,"family":"Anslow","given":"Faron","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":448509,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mix, Alan C.","contributorId":83346,"corporation":false,"usgs":true,"family":"Mix","given":"Alan","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":448508,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Edwards, R.

Only rarely-captured behaviors, such as crouching, might create impressions made by the hands. Such tracks provide valuable information concerning the often poorly understood functional morphology of the early theropod forelimb. Methodology/Principal Findings: Here we describe a well-preserved theropod trackway in a Lower Jurassic (???198 millionyear- old) lacustrine beach sandstone in the Whitmore Point Member of the Moenave Formation in southwestern Utah. The trackway consists of prints of typical morphology, intermittent tail drags and, unusually, traces made by the animal resting on the substrate in a posture very similar to modern birds. The resting trace includes symmetrical pes impressions and well-defined impressions made by both hands, the tail, and the ischial callosity. Conclusions/Significance: The manus impressions corroborate that early theropods, like later birds, held their palms facing medially, in contrast to manus prints previously attributed to theropods that have forward-pointing digits. Both the symmetrical resting posture and the medially-facing palms therefore evolved by the Early Jurassic, much earlier in the theropod lineage than previously recognized, and may characterize all theropods.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1371/journal.pone.0004591","issn":"19326203","usgsCitation":"Milner, A.R., Harris, J., Lockley, M., Kirkland, J., and Matthews, N., 2009, Bird-like anatomy, posture, and behavior revealed by an early jurassic theropod dinosaur resting trace: PLoS ONE, v. 4, no. 3, https://doi.org/10.1371/journal.pone.0004591.","costCenters":[],"links":[{"id":476520,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0004591","text":"Publisher Index Page"},{"id":243742,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215906,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0004591"}],"volume":"4","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-03-04","publicationStatus":"PW","scienceBaseUri":"5059f1b7e4b0c8380cd4adc6","contributors":{"authors":[{"text":"Milner, Andrew R.C.","contributorId":13422,"corporation":false,"usgs":false,"family":"Milner","given":"Andrew","email":"","middleInitial":"R.C.","affiliations":[],"preferred":false,"id":448212,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harris, J.D.","contributorId":105552,"corporation":false,"usgs":true,"family":"Harris","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":448216,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lockley, M.G.","contributorId":34301,"corporation":false,"usgs":true,"family":"Lockley","given":"M.G.","affiliations":[],"preferred":false,"id":448213,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kirkland, J.I.","contributorId":47938,"corporation":false,"usgs":true,"family":"Kirkland","given":"J.I.","email":"","affiliations":[],"preferred":false,"id":448215,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Matthews, N.A.","contributorId":37565,"corporation":false,"usgs":true,"family":"Matthews","given":"N.A.","email":"","affiliations":[],"preferred":false,"id":448214,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Although protected natural areas may act as reservoirs of biological integrity and serve as benchmarks for comparison with unprotected areas, they are not immune from population declines and extinctions and should be monitored. Unfortunately, identifying survey sites and performing long-term fieldwork within such (often remote) areas involves a special set of problems. We used the USDA Natural Resource Conservation Service Soil Survey Geographic (SSURGO) Database to identify, a priori, potential habitat for aquatic-breeding amphibians on North and South Manitou Islands, Sleeping Bear Dunes National Lakeshore, Michigan, and compared the results to those obtained using National Wetland Inventory (NWI) data. The SSURGO approach identified more target sites for surveys than the NWI approach, and it identified more small and ephemeral wetlands. Field surveys used a combination of daytime call surveys, night-time call surveys, and perimeter surveys. We found that sites that would not have been identified with NWI data often contained amphibians and, in one case, contained wetland-breeding species that would not have been found using NWI data. Our technique allows for easy a priori identification of numerous survey sites that might not be identified using other sources of spatial information. We recognize, however, that the most effective site identification and survey techniques will likely use a combination of methods in addition to those described here.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Natural Areas Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.3375/043.029.0203","issn":"08858608","usgsCitation":"Bowen, K., Beever, E., and Gafvert, U., 2009, Improving the design of amphibian surveys using soil data: A case study in two wilderness areas: Natural Areas Journal, v. 29, no. 2, p. 117-125, https://doi.org/10.3375/043.029.0203.","startPage":"117","endPage":"125","numberOfPages":"9","costCenters":[],"links":[{"id":215879,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3375/043.029.0203"},{"id":243713,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a397fe4b0c8380cd61942","contributors":{"authors":[{"text":"Bowen, K.D.","contributorId":56469,"corporation":false,"usgs":true,"family":"Bowen","given":"K.D.","email":"","affiliations":[],"preferred":false,"id":448210,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beever, E.A.","contributorId":80040,"corporation":false,"usgs":true,"family":"Beever","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":448211,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gafvert, U.B.","contributorId":32372,"corporation":false,"usgs":true,"family":"Gafvert","given":"U.B.","email":"","affiliations":[],"preferred":false,"id":448209,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Little Conestoga Creek, Pennsylvania, a tributary to the Susquehanna River and the Chesapeake Bay, is one of these streams. Floodplain sedimentation rates, bank erosion rates, and channel morphology were measured annually during 2004-2007 at five sites along a 28-km length of Little Conestoga Creek with nine colonial era milldams (one dam was still in place in 2007). This study was part of a larger cooperative effort to quantify floodplain sedimentation, bank erosion, and channel morphology in a high sediment yielding region of the Chesapeake Bay watershed. Data from the five sites were used to estimate the annual volume and mass of sediment stored on the floodplain and eroded from the banks for 14 segments along the 28-km length of creek. A bank and floodplain reach based sediment budget (sediment budget) was constructed for the 28 km by summing the net volume of sediment deposited and eroded from each segment. Mean floodplain sedimentation rates for Little Conestoga Creek were variable, with erosion at one upstream site (-5 mm/year) to deposition at the other four sites (highest = 11 mm/year) despite over a meter of floodplain aggradation from postcolonial sedimentation. Mean bank erosion rates range between 29 and 163 mm/year among the five sites. Bank height increased 1 m for every 10.6 m of channel width, from upstream to downstream (R<sup>2</sup> = 0.79, p &lt; 0.0001) resulting in progressively lowered hydraulic connectivity between the channel and the floodplain. Floodplain sedimentation and bank erosion rates also appear to be affected by the proximity of the segments to one existing milldam, which promotes deposition upstream and scouring downstream. The floodplain and bank along the 28-km reach produced a net mean sediment loss of 5,634 Mg/year for 2004-2007, indicating that bank erosion was exceeding floodplain sedimentation. In particular, the three segments between the existing dam and the confluence with the Conestoga River (32% of the studied reach) account for 97% of the measured net sediment budget. Future research directed at understanding channel equilibria should facilitate efforts to reduce the sediment impacts of dam removal and legacy sediment. ?? 2009 American Water Resources Association.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1752-1688.2009.00308.x","issn":"1093474X","usgsCitation":"Schenk, E., and Hupp, C., 2009, Legacy effects of colonial millponds on floodplain sedimentation, bank erosion, and channel morphology, MID-Atlantic, USA: Journal of the American Water Resources Association, v. 45, no. 3, p. 597-606, https://doi.org/10.1111/j.1752-1688.2009.00308.x.","startPage":"597","endPage":"606","numberOfPages":"10","costCenters":[],"links":[{"id":215957,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2009.00308.x"},{"id":243794,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-05-26","publicationStatus":"PW","scienceBaseUri":"505a463de4b0c8380cd675da","contributors":{"authors":[{"text":"Schenk, E.R.","contributorId":101911,"corporation":false,"usgs":true,"family":"Schenk","given":"E.R.","email":"","affiliations":[],"preferred":false,"id":447379,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hupp, C.R. 0000-0003-1853-9197","orcid":"https://orcid.org/0000-0003-1853-9197","contributorId":78775,"corporation":false,"usgs":true,"family":"Hupp","given":"C.R.","affiliations":[],"preferred":false,"id":447378,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The uncertainty associated with the inundation boundaries is seldom quantified, in part, because all of the sources of uncertainty are not recognized and because data available to quantify uncertainty seldom are available. Sources of uncertainty discussed in this paper include hydrologic data used for hydraulic model development and validation, topographic data, and the hydraulic model. The assumption of steady flow, which typically is made to produce inundation maps, has less of an effect on predicted inundation at lower flows than for higher flows because more time typically is required to inundate areas at high flows than at low flows. Difficulties with establishing reasonable cross sections that do not intersect and that represent water-surface slopes in tributaries contribute additional uncertainties in the hydraulic modelling. As a result, uncertainty in the flood inundation polygons simulated with a one-dimensional model increases with distance from the main channel.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Flood Risk Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley-Blackwell Publishing Ltd.","publisherLocation":"Oxford, England","doi":"10.1111/j.1753-318X.2009.01029.x","usgsCitation":"Bales, J., and Wagner, C.R., 2009, Sources of uncertainty in flood inundation maps: Journal of Flood Risk Management, v. 2, no. 2, p. 139-147, https://doi.org/10.1111/j.1753-318X.2009.01029.x.","productDescription":"9 p.","startPage":"139","endPage":"147","numberOfPages":"9","costCenters":[],"links":[{"id":476446,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1753-318x.2009.01029.x","text":"Publisher Index Page"},{"id":215601,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1753-318X.2009.01029.x"},{"id":243415,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"2","noUsgsAuthors":false,"publicationDate":"2009-05-26","publicationStatus":"PW","scienceBaseUri":"505b9397e4b08c986b31a59d","contributors":{"authors":[{"text":"Bales, J.

The model predicts that, when a generalist herbivore feeds in the absence of plant toxins, adaptive foraging generally increases the probability of coexistence of plant species populations, because the herbivore switches more of its effort to whichever plant species is more common and accessible. In contrast, toxin-determined selective herbivory can drive plant succession toward dominance by the more toxic species, as previously documented in boreal forests and prairies. When the toxin concentrations in different plant species are similar, but species have different toxins with nonadditive effects, herbivores tend to diversify foraging efforts to avoid high intakes of any one toxin. This diversification leads the herbivore to focus more feeding on the less common plant species. Thus, uncommon plants may experience depensatory mortality from herbivory, reducing local species diversity. The depensatory effect of herbivory may inhibit the invasion of other plant species that are more palatable or have different toxins. These predictions were tested and confirmed in the Alaskan boreal forest. ?? 2009 Springer Science+Business Media, LLC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10021-009-9240-x","issn":"14329840","usgsCitation":"Feng, Z., Liu, R., DeAngelis, D., Bryant, L.C., Kielland, K., Stuart, C.F., and Swihart, R., 2009, Plant toxicity, adaptive herbivory, and plant community dynamics: Ecosystems, v. 12, no. 4, p. 534-547, https://doi.org/10.1007/s10021-009-9240-x.","startPage":"534","endPage":"547","numberOfPages":"14","costCenters":[],"links":[{"id":215570,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10021-009-9240-x"},{"id":243382,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-03-10","publicationStatus":"PW","scienceBaseUri":"505a7c02e4b0c8380cd79744","contributors":{"authors":[{"text":"Feng, Z.","contributorId":84991,"corporation":false,"usgs":true,"family":"Feng","given":"Z.","email":"","affiliations":[],"preferred":false,"id":447046,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, R.","contributorId":23731,"corporation":false,"usgs":true,"family":"Liu","given":"R.","email":"","affiliations":[],"preferred":false,"id":447042,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"DeAngelis, D.L. 0000-0002-1570-4057","orcid":"https://orcid.org/0000-0002-1570-4057","contributorId":32470,"corporation":false,"usgs":true,"family":"DeAngelis","given":"D.L.","affiliations":[],"preferred":false,"id":447044,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bryant, Lee C.","contributorId":62045,"corporation":false,"usgs":false,"family":"Bryant","given":"Lee","email":"","middleInitial":"C.","affiliations":[{"id":12698,"text":"Northern Arizona University","active":true,"usgs":false}],"preferred":true,"id":447045,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kielland, K.","contributorId":98932,"corporation":false,"usgs":true,"family":"Kielland","given":"K.","affiliations":[],"preferred":false,"id":447048,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stuart, Chapin F.","contributorId":23781,"corporation":false,"usgs":true,"family":"Stuart","given":"Chapin","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":447043,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Swihart, R.K.","contributorId":90560,"corporation":false,"usgs":true,"family":"Swihart","given":"R.K.","email":"","affiliations":[],"preferred":false,"id":447047,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Estuaries are susceptible to hurricane pulses and are thought to be resilient to habitat change, because biotic communities often return quickly to pre-hurricane conditions. Although several examples provide evidence of quick recovery of estuarine nekton communities following a hurricane, few studies take place in tidal freshwater habitat where physical habitat effects can be extensive and may not be readily mitigated. We examined nekton communities (density, biomass, ?? and ?? diversity, % occurrence by residence status) in tidal freshwater marshes in Breton Sound, Louisiana, before and after a direct hit by Hurricane Katrina (2005). Vegetative marsh loss in the study area was extensive, and elevated salinity persisted for almost 6 months. Post-Katrina nekton density and biomass increased significantly, and the nekton community shifted from one of tidal freshwater/resident species to one containing brackish/migrant species, many of which are characterized by pelagic and benthic life history strategies. By spring 2007, the nekton community had shifted back to tidal freshwater/resident species, despite the enduring loss of vegetated marsh habitat. ?? 2009 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Estuarine, Coastal and Shelf Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecss.2009.03.016","issn":"02727714","usgsCitation":"Piazza, B.P., and La Peyre, M., 2009, The effect of Hurricane Katrina on nekton communities in the tidal freshwater marshes of Breton Sound, Louisiana, USA: Estuarine, Coastal and Shelf Science, v. 83, no. 1, p. 97-104, https://doi.org/10.1016/j.ecss.2009.03.016.","startPage":"97","endPage":"104","numberOfPages":"8","costCenters":[],"links":[{"id":215983,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecss.2009.03.016"},{"id":243822,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bab10e4b08c986b322bbe","contributors":{"authors":[{"text":"Piazza, Bryan P.","contributorId":11022,"corporation":false,"usgs":true,"family":"Piazza","given":"Bryan","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":447026,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"La Peyre, M.K. 0000-0001-9936-2252","orcid":"https://orcid.org/0000-0001-9936-2252","contributorId":102239,"corporation":false,"usgs":true,"family":"La Peyre","given":"M.K.","affiliations":[],"preferred":false,"id":447027,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The purpose of the study was to compare methods for extraction of faecal bacteria from sands and recommend a standardized extraction technique. Methods and Results: Twenty-two methods of extracting enterococci and Escherichia coli from sand were evaluated, including multiple permutations of hand shaking, mechanical shaking, blending, sonication, number of rinses, settling time, eluant-to-sand ratio, eluant composition, prefiltration and type of decantation. Tests were performed on sands from California, Florida and Lake Michigan. Most extraction parameters did not significantly affect bacterial enumeration. anova revealed significant effects of eluant composition and blending; with both sodium metaphosphate buffer and blending producing reduced counts. Conclusions: The simplest extraction method that produced the highest FIB recoveries consisted of 2 min of hand shaking in phosphate-buffered saline or deionized water, a 30-s settling time, one-rinse step and a 10 : 1 eluant volume to sand weight ratio. This result was consistent across the sand compositions tested in this study but could vary for other sand types. Significance and Impact of the Study: Method standardization will improve the understanding of how sands affect surface water quality. ?? 2009 The Society for Applied Microbiology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Microbiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2672.2009.04440.x","issn":"13645072","usgsCitation":"Boehm, A., Griffith, J., McGee, C., Edge, T., Solo-Gabriele, H.M., Whitman, R., Cao, Y., Getrich, M., Jay, J., Ferguson, D., Goodwin, K., Lee, C., Madison, M., and Weisberg, S., 2009, Faecal indicator bacteria enumeration in beach sand: A comparison study of extraction methods in medium to coarse sands: Journal of Applied Microbiology, v. 107, no. 5, p. 1740-1750, https://doi.org/10.1111/j.1365-2672.2009.04440.x.","startPage":"1740","endPage":"1750","numberOfPages":"11","costCenters":[],"links":[{"id":487801,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/2810257","text":"External Repository"},{"id":215719,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2672.2009.04440.x"},{"id":243541,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"107","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0edee4b0c8380cd5366f","contributors":{"authors":[{"text":"Boehm, A.B.","contributorId":87770,"corporation":false,"usgs":true,"family":"Boehm","given":"A.B.","email":"","affiliations":[],"preferred":false,"id":446600,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Griffith, J.","contributorId":6686,"corporation":false,"usgs":true,"family":"Griffith","given":"J.","affiliations":[],"preferred":false,"id":446589,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McGee, C.","contributorId":102709,"corporation":false,"usgs":true,"family":"McGee","given":"C.","email":"","affiliations":[],"preferred":false,"id":446602,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Edge, T.A.","contributorId":78960,"corporation":false,"usgs":true,"family":"Edge","given":"T.A.","email":"","affiliations":[],"preferred":false,"id":446599,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Solo-Gabriele, H.

Detecting how the pre-drainage hydrological system has been altered is crucial to preserving its functional attributes. However, reliable tools for hindcasting historic conditions in the Everglades are limited. A recent synthesis demonstrates that the proportion of surface-water inflows has increased relative to precipitation, accounting for 33% of total inputs compared with 18% historically. The largest new source of water is canal drainage from areas of former wetlands converted to agriculture. Interactions between groundwater and surface water have also increased, due to increasing vertical hydraulic gradients resulting from topographic and water-level alterations on the otherwise extremely flat landscape. Environmental solute tracer data were used to determine groundwater's changing role, from a freshwater storage reservoir that sustained the Everglades ecosystem during dry periods to a reservoir of increasingly degraded water quality.

Here an antecedent rainfall and convolution model was used to separate a karst watershed hydrograph into two outflow components: one originating from focused recharge in conduits and one originating from slow flow in a porous annex system. In convolution, parameters of a complex system are lumped together in the impulse-response function (IRF), which describes the response of the system to an impulse of effective precipitation. Two parametric functions in superposition approximate the two-domain IRF. The outflow hydrograph can be separated into flow components by forward modeling with isolated IRF components, which provides an objective criterion for separation. As an example, the model was applied to a karst watershed in the Madison aquifer, South Dakota, USA. Simulation results indicate that this watershed is characterized by a flashy response to storms, with a peak response time of 1 day, but that 89% of the flow results from the slow-flow domain, with a peak response time of more than 1 year. This long response time may be the result of perched areas that store water above the main water table. Simulation results indicated that some aspects of the system are stationary but that nonlinearities also exist.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2008.11.001","issn":"00221","usgsCitation":"Long, A., 2009, Hydrograph separation for karst watersheds using a two-domain rainfall-discharge model: Journal of Hydrology, v. 364, no. 3-4, p. 249-256, https://doi.org/10.1016/j.jhydrol.2008.11.001.","startPage":"249","endPage":"256","numberOfPages":"8","costCenters":[],"links":[{"id":213819,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2008.11.001"},{"id":241479,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"364","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a34f6e4b0c8380cd5fb7b","contributors":{"authors":[{"text":"Long, Andrew J.","contributorId":80023,"corporation":false,"usgs":false,"family":"Long","given":"Andrew J.","affiliations":[],"preferred":false,"id":436424,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This project quantifies carbon stocks and fluxes in the humid forest zone of Ghana, as a part of an assessment in West Africa. The General Ensemble biogeochemical Modeling System (GEMS) was used to simulate the responses of natural and managed systems to projected scenarios of changes in climate, land use and cover, and nitrogen fertilization in the Assin district of Ghana. Model inputs included historical land use and cover data, historical climate records and projected climate changes, and national management inventories. Our results show that deforestation for crop production led to a loss of soil organic carbon (SOC) by 33% from 1900 to 2000. The results also show that the trend of carbon emissions from cropland in the 20th century will continue through the 21st century and will be increased under the projected warming and drying scenarios.
