These species exhibit the most consistent population declines of any group of North American birds during the past 40 years. Anecdotal evidence suggests these declines have been occurring for nearly a century (Peterjohn and Sauer 1999). While the widespread conversion of grasslands into other habitats contributed to these declining populations, other factors such as habitat fragmentation and mowing regimes are also implicated (Vickery et al. 1999a). This plight of grassland birds has heightened awareness of the need for concerted conservation actions to reverse these seriously declining population trends. </p><p>The National Park Service (NPS) is positioned to potentially contribute to grassland bird conservation in the Mid-Atlantic Region. The NPS maintains a number of historic sites and former battlefields that are managed for their cultural significance but also support wildlife populations. Many of these “cultural parks” maintain open landscapes to recreate land use patterns that existed at the times of the historical events. These open landscapes are primarily managed grasslands which could be maintained to benefit grassland birds. </p><p>In 2005, the NPS initiated a project exploring the potential of “cultural parks” to support significant breeding grassland bird communities. This project involved parks within three NPS Inventory and Monitoring Program (I&amp;M) networks, Mid-Atlantic, National Capital, and Eastern Rivers and Mountains. Five parks were selected for the initial focus of this study, all of which maintain open landscapes for interpretation of historic events. Most parks were selected because they represent the most extensive grassland habitats within their networks, with the rationale that if these parks cannot support significant breeding grassland bird communities, then parks with smaller acreages cannot support these communities either. The five parks included in this study are: Antietam National Battlefield, Fort Necessity National Battlefield, Gettysburg National Battlefield, Manassas National Battlefield, and Monocacy National Battlefield. </p><p>This conceptual ecological model is one product of this project. The information presented below allows NPS Network Coordinators to understand the factors to consider when making decisions concerning grassland management within their networks. This model provides park Resource Managers with information on grassland ecology in the Mid-Atlantic Region, the ecological requirements of grassland birds likely to occur in their parks, and management issues that influence whether significant breeding populations can be expected to occupy grasslands created and maintained in the parks. The Resource Managers can then make informed decisions concerning their ability to create and maintain grassland habitats. </p><p>The emphasis of this conceptual model is restricted to management of breeding grassland birds. Additional species may occur in this region during migration and winter, while habitat requirements of all grassland birds during nonbreeding seasons will differ from those described for the breeding season.</p>","language":"English","publisher":"U.S. Department of the Interior, National Park Service","publisherLocation":"Philadelphia, PA","usgsCitation":"Peterjohn, B.G., 2006, Conceptual ecological model for management of breeding grassland birds in the Mid-Atlantic Region: Natural Resource Report NPS/NER/NRR--2006/005, vii, 43 p.","productDescription":"vii, 43 p.","numberOfPages":"56","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":329063,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":329062,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://irma.nps.gov/DataStore/DownloadFile/152719","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57ed5314e4b090825011d517","contributors":{"authors":[{"text":"Peterjohn, Bruce G. bpeterjohn@usgs.gov","contributorId":4493,"corporation":false,"usgs":true,"family":"Peterjohn","given":"Bruce","email":"bpeterjohn@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":649845,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Our primary study objective was to quantify the effect of change in winter temperature and precipitation on watershed hydrology and solute flux. During the study winter runoff was correlated with precipitation, and forest soils beneath the snowpack remained unfrozen. Winter air temperature and soil temperature beneath the snowpack increased while precipitation and snowmelt declined. Atmospheric inputs declined for H+, NO 3- , NH 4+ , dissolved inorganic nitrogen (DIN), and SO 42- . Replicated plot-level results, which could not be directly extrapolated to the watershed scale, showed 90% of atmospheric DIN input was retained in surface shallow (<15 cm deep) soils while SO 42- flux increased 70% and dissolved organic carbon (DOC) 30-fold. Most stream water base cation (C B), HCO 3- , and Cl- concentrations declined with increased stream water discharge, K+, NO 3- , and SO 42- remained unchanged, and DOC and dissolved organic nitrogen (DON) increased. Winter stream water solute outputs declined or were unchanged with time except for NO 3- and DOC which increased. DOC and DIN outputs were correlated with the percentage of winter runoff and stream discharge that occurred when subsurface flow at the plot-level was shallow (<25 cm beneath Oi). Study results suggest that the percentage of annual runoff occurring as shallow lateral subsurface flow may be a major factor regulating solute outputs and concentrations in snowmelt-dominated ecosystems. ??

With subsidence occurring at a rate of around 10 cm per year since discovery, monitoring has been beneficial to ensure public safety and optimize maintenance. A miniSOSIE reflection survey conducted in 1980 delineated the affected subsurface and successfully predicted development of a third sinkhole at this site. In 2004 and 2005 a high-resolution vibroseis survey was completed to ascertain current conditions of the subsurface, rate and pattern of growth since 1980, and potential for continued growth. With time and improved understanding of the salt dissolution affected subsurface in this area it appears that these features represent little risk to the public from catastrophic failure. However, from an operational perspective the Kansas Department of Transportation should expect continued subsidence, with future increases in surface area likely at a slightly reduced vertical rate.

Progress Report August 2005","docAbstract":"<p>The occurrence of large, severe fires in southwestern ponderosa pine (Pinus ponderosa) forests has resulted in concern that these forests may not persist under such an extreme disturbance regime. In our research, we are examining the outcomes of high-severity fire in ponderosa pine forests and their neighboring communities across an elevational gradient. One goal of our work is to contribute to understanding the resiliency of these systems, but we also want to investigate the conservation values intrinsic to the diverse communities that represent alternative successional trajectories after severe fire. One assumption of our research is that the spatial pattern of a disturbance becomes increasingly important when the disturbance is large and biological legacies are few and sparse. We ask, therefore, what spectrum of plant communities results from high severity fire, and what is their relationship to spatial patterns of severity mapped in early post fire timeframes? Also, do spatial patterns of older burns (1950&ndash;80) differ from recent burns (1998&ndash;present) in ways that make us expect successional changes years from now to differ from those we observed at our older burn field sites?</p>\n<p>Here, we describe the first stages of our work in mapping burn severity at old and new burns as well as the work we have recently completed at our two field sites.

As part of the Deschutes River Estuary Feasibility Study (DEFS), the United States Geological Survey (USGS) was tasked to model how tidal and storm processes will influence the river, lake and lower Budd Inlet should estuary restoration occur. Understanding these mechanisms will assist in developing a scientifically sound assessment on the feasibility of restoring the estuary.</p>\n<br>\n<p>The goals of the DEFS are as follows.</p>\n<br>\n<p>- Increase understanding of the estuary alternative to the same level as managing the lake environment.</p>\n<p>- Determine the potential to create a viable, self sustaining estuary at Capitol Lake, given all the existing physical constraints and the urban setting.</p>\n<p>- Create a net-benefit matrix which will allow a fair evaluation of overall benefits and costs of various alternative scenarios.</p>\n<p>- Provide the completed study to the CLAMP Steering Committee so that a recommendation about a long-term aquatic environment of the basin can be made.</p>\n<br>\n<p>The hydrodynamic and sediment transport modeling task developed a number of different model simulations using a process-based morphological model, Delft3D, to help address these goals. Modeling results provide a qualitative assessment of estuarine behavior both prior to dam construction and after various post-dam removal scenarios. Quantitative data from the model is used in the companion biological assessment and engineering design components of the overall study.</p>\n<br>\n<p>Overall, the modeling study found that after dam removal, tidal and estuarine processes are immediately restored, with marine water from Budd Inlet carried into North and Middle Basin on each rising tide and mud flats being exposed with each falling tide. Within the first year after dam removal, tidal processes, along with the occasional river floods, act to modify the estuary bed by redistributing sediment through erosion and deposition. The morphological response of the bed is rapid during the first couple of years, then slows as a dynamic equilibrium is reached within three to five years. By ten years after dam removal, the overall hydrodynamic and morphologic behavior of the estuary is similar to the pre-dam estuary, with the exception of South Basin, which has been permanently modified by human activities.</p>\n<br>\n<p>In addition to a qualitative assessment of estuarine behavior, process-based modeling provides the ability address specific questions to help to inform decision-making. Considering that predicting future conditions of a complex estuarine environment is wrought with uncertainties, quantitative results in this report are often expressed in terms of ranges of possible outcomes.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20061318","usgsCitation":"George, D.A., Gelfenbaum, G., Lesser, G., and Stevens, A., 2006, Deschutes Estuary feasibility study: Hydrodynamics and sediment transport modeling (Version 1.0): U.S. Geological Survey Open-File Report 2006-1318, Report: 222 p.; 2 Appendixes: 177 p.; Metadata, https://doi.org/10.3133/ofr20061318.","productDescription":"Report: 222 p.; 2 Appendixes: 177 p.; Metadata","temporalStart":"2005-02-16","temporalEnd":"2005-02-17","costCenters":[{"id":645,"text":"Western Coastal and Marine Geology","active":false,"usgs":true}],"links":[{"id":420428,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_80585.htm","linkFileType":{"id":5,"text":"html"}},{"id":9208,"rank":5,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2006/1318/","linkFileType":{"id":5,"text":"html"}},{"id":192369,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":295746,"rank":4,"type":{"id":16,"text":"Metadata"},"url":"https://pubs.usgs.gov/of/2006/1318/CapitolLakeSeds.html","linkFileType":{"id":5,"text":"html"}},{"id":295744,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2006/1318/of2006-1318.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":295745,"rank":2,"type":{"id":3,"text":"Appendix"},"url":"https://pubs.usgs.gov/of/2006/1318/of2006-1318_appendixes.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Washington","otherGeospatial":"Deschutes Estuary","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.9133,\n              47.0619\n            ],\n            [\n              -122.9133,\n              47.0183\n            ],\n            [\n              -122.8914,\n              47.0183\n            ],\n            [\n              -122.8914,\n              47.0619\n            ],\n            [\n              -122.9133,\n              47.0619\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab0e4b07f02db66dd64","contributors":{"authors":[{"text":"George, Douglas A.","contributorId":60328,"corporation":false,"usgs":true,"family":"George","given":"Douglas","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":290306,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gelfenbaum, Guy","contributorId":79844,"corporation":false,"usgs":true,"family":"Gelfenbaum","given":"Guy","affiliations":[],"preferred":false,"id":290307,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lesser, Giles","contributorId":88216,"corporation":false,"usgs":true,"family":"Lesser","given":"Giles","email":"","affiliations":[],"preferred":false,"id":290308,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stevens, Andrew W.","contributorId":89093,"corporation":false,"usgs":true,"family":"Stevens","given":"Andrew W.","affiliations":[],"preferred":false,"id":290309,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Unlike the Colorado pikeminnow and humpback chub, wild populations of the bonytail and razorback sucker are either extirpated from the mainstem river or are nearly so. Agencies are aggressively stocking these fish and while repatriated fish spawn, their young are rapidly eaten by introduced predators. A decade of predator removal efforts has proved ineffective in restoring natural recruitment. Today, the presence of these species is totally dependent on stocking, suggesting both species are worse off today than when recovery efforts began nearly two decades ago.</p>\n<p>In contrast, both species readily produce young in ponds where nonnative predators are absent. Evidence shows they evolved with the ability to spawn in both flowing and standing water, which suggests isolated oxbow communities may have been an essential feature in their evolution and survival strategy.</p>\n<p>Sustainable populations during the past few decades have only occurred in isolated ponds devoid of predatory nonnative fish. Efforts to force recovery in the main channel river continue to fail due to the presence of nonnative predators that may be economically important recreational species. Off-channel sanctuaries provide research and management opportunities on a scale that are both biologically and economically realistic. Effective management of these species in small habitats appears to be the most logical approach to advance recovery in larger river reaches.</p>\n<p>This report presents new findings, updates existing information, and describes what may well represent the only practical approach to these species&rsquo; conservation and recovery. Chapter 1 provides an overview of the Colorado River system from its origin to the Gulf of California and includes a description of propagation and stocking programs which have not been described elsewhere. The report also updates what is known or suspected on the life history and ecology of these two endangered fishes. Chapter 2 describes the successful recruitment of both species at an oxbow pond on the Cibola National Wildlife Refuge in Arizona, discusses factors that contribute to completion of the life cycle of both fishes, and provides recommendations for future management of the impoundment. Chapter 3 provides historical evidence that oxbow habitats were formed historically in years of high runoff and the importance of these habitats for survival and evolution of native fishes. It also summarizes key features of habitats that can serve as sanctuaries that enhance early survival of the endangered fishes and allow the fish to complete their entire life cycles.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20065065","usgsCitation":"Mueller, G.A., 2006, Ecology of bonytail and razorback sucker and the role of off-channel habitats in their recovery: U.S. Geological Survey Scientific Investigations Report 2006-5065, viii, 64 p., https://doi.org/10.3133/sir20065065.","productDescription":"viii, 64 p.","numberOfPages":"74","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":194605,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20065065.PNG"},{"id":320226,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2006/5065/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ee4b07f02db627ab0","contributors":{"authors":[{"text":"Mueller, Gordon A.","contributorId":86420,"corporation":false,"usgs":true,"family":"Mueller","given":"Gordon","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":288111,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We mapped occurrence of woody riparian plant communities along 58 km of the San Miguel River in southwestern Colorado. We determined the recurrence interval of inundation for each plant community by combining step-backwater hydraulic modeling at 4 representative reaches with Log-Pearson analysis of 4 stream gaging stations. Finally, we mapped bottomland surficial geology and used a Geographic Information System to overlay the coverages of geology and vegetation. Plant communities were distinctly arrayed along the hydrologic gradient. The <i>Salix exigua</i> Nuttall (sand-bar willow) community occurred mostly on surfaces with a recurrence interval of inundation shorter than 2.2 years; the <i>Betula occidentalis</i> Hooker (river birch) community peaked on sites with recurrence intervals of inundation between 2.2 and 4.6 years. The hydrologic position occupied by communities dominated by <i>Populus angustifolia</i> James (narrowleaf cottonwood) was strongly related to age of trees and species composition of understory shrubs. The fraction of riparian vegetation on surfaces historically inundated by the river decreased in the upstream direction from almost 100% near Uravan to &lt;50% along the South Fork of the San Miguel River. In upstream reaches much of the physical disturbance necessary to maintain riparian vegetation is provided by valley-side processes including debris flows, floods from minor tributaries, landslides, and beaver activity. Where valley-side processes are important, prediction of riparian vegetation change based on alterations of river flow will be incomplete.</p>","language":"English","publisher":"Brigham Young University","doi":"10.3398/1527-0904(2006)66[78:TALVIW]2.0.CO;2","usgsCitation":"Friedman, J.M., Auble, G., Andrews, E., Kittel, G., Madole, R., Griffin, E., and Allred, T.M., 2006, Transverse and longitudinal variation in woody riparian vegetation along a montane river: Western North American Naturalist, v. 66, no. 1, p. 78-91, https://doi.org/10.3398/1527-0904(2006)66[78:TALVIW]2.0.CO;2.","productDescription":"p. 78-91","startPage":"78","endPage":"91","numberOfPages":"14","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":488724,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://scholarsarchive.byu.edu/wnan/vol66/iss1/7","text":"External Repository"},{"id":130095,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"66","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4de4b07f02db626cb1","contributors":{"authors":[{"text":"Friedman, Jonathan M. 0000-0002-1329-0663","orcid":"https://orcid.org/0000-0002-1329-0663","contributorId":44495,"corporation":false,"usgs":true,"family":"Friedman","given":"Jonathan","middleInitial":"M.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":322248,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Auble, G.T.","contributorId":19505,"corporation":false,"usgs":true,"family":"Auble","given":"G.T.","email":"","affiliations":[],"preferred":false,"id":322245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Andrews, E.D.","contributorId":13922,"corporation":false,"usgs":true,"family":"Andrews","given":"E.D.","email":"","affiliations":[],"preferred":false,"id":322243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kittel, G.","contributorId":36082,"corporation":false,"usgs":true,"family":"Kittel","given":"G.","email":"","affiliations":[],"preferred":false,"id":322247,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Madole, R.F. 0000-0002-9081-570X","orcid":"https://orcid.org/0000-0002-9081-570X","contributorId":34086,"corporation":false,"usgs":true,"family":"Madole","given":"R.F.","affiliations":[],"preferred":false,"id":322246,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Griffin, E.R.","contributorId":15143,"corporation":false,"usgs":true,"family":"Griffin","given":"E.R.","email":"","affiliations":[],"preferred":false,"id":322244,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Allred, Tyler M.","contributorId":173170,"corporation":false,"usgs":false,"family":"Allred","given":"Tyler","email":"","middleInitial":"M.","affiliations":[{"id":27172,"text":"Allred Restoration, Inc., Tremonton, UT","active":true,"usgs":false}],"preferred":false,"id":322249,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

The concentration of Cd bound to non‐MTLPs (representing potentially Cd‐sensitive proteins) was significantly greater in the insects from the reference site (134 ± 7 ng/g) than in those from the contaminated site (42 ± 2 ng/g). At the end of the depuration period, 90% of the accumulated Cd body burden had been eliminated, and Cd concentrations in MTLPs and non‐MTLPs were similar between the sites.

We measured denitrification rates seasonally on sediments underlying zebra mussel beds collected from the impounded zone of Navigation Pool 8 of the Upper Mississippi River. Denitrification assays were amended with nutrients to characterize variation in nutrient limitation of denitrification in the presence or absence of zebra mussels. Denitrification rates at zebra mussel sites were high relative to sites without zebra mussels in February 2004 (repeated measures analysis of variance (RM ANOVA), <i>p</i> = 0.005), potentially because of high NO<sub>3</sub>-N variability from nitrification of high NH<sub>4</sub><sup>+</sup> zebra mussel waste. Denitrification rates were highest in June 2003 (RM ANOVA, <i>p</i> < 0.001), corresponding with the highest NO<sub>3</sub>-N concentrations during the study (linear regression, R<sup>2</sup> = 0.72, <i>p</i> < 0.001). Denitrification was always N-limited, but sites without zebra mussels showed the strongest response to N amendments relative to sites with zebra mussels (two-way ANOVA, <i>p</i> &le; 0.01). Examining how zebra mussels influence denitrification rates will aid in developing a more complete understanding of the impact of zebra mussels and more effective management strategies of eutrophic waters.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"NRC Research Press","publisherLocation":"Ottawa, Ontario","doi":"10.1139/F06-002","issn":"0706652X","usgsCitation":"Bruesewitz, D.A., Tank, J., Bernot, M.J., Richardson, W.B., and Strauss, E.A., 2006, Seasonal effects of the zebra mussel (<i>Dreissena polymorpha</i>) on sediment denitrification rates in Pool 8 of the Upper Mississippi River: Canadian Journal of Fisheries and Aquatic Sciences, v. 63, no. 5, p. 957-969, https://doi.org/10.1139/F06-002.","productDescription":"13 p.","startPage":"957","endPage":"969","numberOfPages":"13","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":211810,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/F06-002"},{"id":239175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":258066,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://yosemite.epa.gov/sab/sabhap.nsf/e1853c0b6014d36585256dbf005c5b71/347790e9183c442a85257205005f7f10/$FILE/Bruesewitz2006SedimentDenitrification.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","otherGeospatial":"Upper Mississippi River","volume":"63","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b889ce4b08c986b316a72","contributors":{"authors":[{"text":"Bruesewitz, Denise A.","contributorId":72590,"corporation":false,"usgs":true,"family":"Bruesewitz","given":"Denise","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":427474,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tank, Jennifer L.","contributorId":103870,"corporation":false,"usgs":true,"family":"Tank","given":"Jennifer L.","affiliations":[],"preferred":false,"id":427475,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bernot, Melody J.","contributorId":66482,"corporation":false,"usgs":true,"family":"Bernot","given":"Melody","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":427473,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Richardson, William B. 0000-0002-7471-4394 wrichardson@usgs.gov","orcid":"https://orcid.org/0000-0002-7471-4394","contributorId":3277,"corporation":false,"usgs":true,"family":"Richardson","given":"William","email":"wrichardson@usgs.gov","middleInitial":"B.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":427471,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Strauss, Eric A.","contributorId":54395,"corporation":false,"usgs":true,"family":"Strauss","given":"Eric","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":427472,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Adsorption and desorption are hypothesized to be the major processes controlling As solubility in oxidized surface sediments where arsenate [As(V)] is dominant. This study examined the relationship between sorption processes and arsenic solubility in shallow sediments from the dry Tulare Lake bed by determining sorption isotherms, pH effect on solubility, and desorption-readsorption behavior (hysteresis), and by using a surface complexation model to describe sorption. The sediments showed a high capacity to adsorb As(V). Estimates of the maximum adsorption capacity were 92 mg As kg- 1 at pH 7.5 and 70 mg As kg- 1 at pH 8.5 obtained using the Langmuir adsorption isotherm. Soluble arsenic [> 97% As(V)] did not increase dramatically until above pH 10. In the native pH range (7.5-8.5), soluble As concentrations were close to the lowest, indicating that As was strongly retained on the sediment. A surface complexation model, the constant capacitance model, was able to provide a simultaneous fit to both adsorption isotherms (pH 7.5 and 8.5) and the adsorption envelope (pH effect on soluble As), although the data ranges are one order of magnitude different. A hysteresis phenomenon between As adsorbed on the sediment and As in solution phase was observed in the desorption-readsorption processes and differs from conventional hysteresis observed in adsorption-desorption processes. The cause is most likely due to modification of adsorbent surfaces in sediment samples upon extensive extractions (or desorption). The significance of the hysteresis phenomenon in affecting As solubility and mobility may be better understood by further microscopic studies of As interaction mechanisms with sediments subjected to extensive leaching in natural environments. ?? 2006 Elsevier B.V.

Based on stratigraphic correlation and diagnostic artifact seriation, Suwannee-age sites have been relatively dated from ??? 10,900 14C yr B.P to ??? 10,500 14C yr B.P. Clovis-like traits on the Suwannee points and other stone tools from the Ryan/Harley site suggest it dates to the earlier end of the Suwannee timeframe. The currently inundated site is partially buried beneath a sediment column located in a swamp forest and partially exposed in a side channel section of the Wacissa River, Jefferson County, Florida. Research done prior to this analysis determined that the artifact assemblage appeared to be unsorted and was contained in a midden-like unit. Our purpose here is to assess the issue of site integrity further. Unconsolidated sediment samples collected from the artifact-bearing horizon and from horizons immediately above and below the artifact horizon were analyzed using granulometric techniques. Arithmetic probability plots of the grain-size distributions show that the sediments were transported and deposited by fluvial processes. Thus, the Suwannee points and associated artifacts, and faunal remains appear to have accumulated during a time of subaerial exposure perhaps after a regional water-table decline, and have remained largely or essentially intact, with little or no postdepositional reworking. The artifacts and faunal remains recovered from the artifact-bearing horizon at Ryan/Harley are distributed randomly, showing no sign of sorting. In the fossil suite, two articulated white-tailed deer (Odocoileus virginianus) vertebra were recovered in situ. The unsorted nature of artifacts and articulated faunal remains that are contained within the fluvially deposited sediments suggests the Suwannee point level of the Ryan/Harley site has remained undisturbed since original deposition. ?? 2006 Wiley Periodicals, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geoarchaeology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/gea.20109","issn":"08836353","usgsCitation":"Balsillie, J.H., Means, G., and Dunbar, J., 2006, The Ryan/Harley site: Sedimentology of an inundated Paleoindian site in north Florida: Geoarchaeology, v. 21, no. 4, p. 363-391, https://doi.org/10.1002/gea.20109.","startPage":"363","endPage":"391","numberOfPages":"29","costCenters":[],"links":[{"id":211870,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/gea.20109"},{"id":239243,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"4","noUsgsAuthors":false,"publicationDate":"2006-03-03","publicationStatus":"PW","scienceBaseUri":"505ba8c5e4b08c986b321e35","contributors":{"authors":[{"text":"Balsillie, J.

Among the four storms, there was an increase in water yields from 2 to 14%. These water yields were much less than in studies of storms in previous years at this same watershed when antecedent moisture conditions were higher. In the current study, early storms resulted in relatively small changes in water chemistry. With progressive storms the changes in water chemistry became more marked with particularly major changes in C<sub>b</sub><span>&nbsp;</span>(sum of base cations), Si, NO<span class=\"Stack\"><span>&nbsp;</span><sub>3</sub><span>&nbsp;</span><sup>−</sup><span>&nbsp;</span></span>, and SO<span class=\"Stack\"><span>&nbsp;</span><sub>4</sub><span>&nbsp;</span><sup>2−</sup><span>&nbsp;</span></span>, DOC and pH. Analyses of the relationships between Si, DOC, discharge and water table height clearly indicated that there was a decrease in ground water contributions (i.e., lower Si concentrations and higher DOC concentrations) as the watershed wetness increased with storm succession. The marked changes in chemistry were also reflected in changes in the isotopic composition of SO<span class=\"Stack\"><span>&nbsp;</span><sub>4</sub><span>&nbsp;</span><sup>2−</sup><span>&nbsp;</span></span>and NO<span class=\"Stack\"><span>&nbsp;</span><sub>3</sub><span>&nbsp;</span><sup>−</sup><span>&nbsp;</span></span>.

Although these late summer and fall storms did not play a major role in the overall annual mass balances of solutes for this watershed, these events had distinctive chemistry including depressed pH and therefore have important consequences to watershed processes such as episodic acidification, and the linkage of these processes to climate change.</p><div class=\"KeywordGroup\" lang=\"en\"><br data-mce-bogus=\"1\"></div>","language":"English","publisher":"Springer","doi":"10.1007/s10533-005-4277-1","issn":"01682563","usgsCitation":"Mitchell, M., Piatek, K., Christopher, S., Mayer, B., Kendall, C., and McHale, P., 2006, Solute sources in stream water during consecutive fall storms in a northern hardwood forest watershed: A combined hydrological, chemical and isotopic approach: Biogeochemistry, v. 78, no. 2, p. 217-246, https://doi.org/10.1007/s10533-005-4277-1.","productDescription":"30 p.","startPage":"217","endPage":"246","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":239244,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211871,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10533-005-4277-1"}],"volume":"78","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9253e4b08c986b319e3f","contributors":{"authors":[{"text":"Mitchell, M.J.","contributorId":72940,"corporation":false,"usgs":true,"family":"Mitchell","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":427634,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Piatek, K.B.","contributorId":72583,"corporation":false,"usgs":true,"family":"Piatek","given":"K.B.","email":"","affiliations":[],"preferred":false,"id":427633,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Christopher, S.","contributorId":33528,"corporation":false,"usgs":true,"family":"Christopher","given":"S.","email":"","affiliations":[],"preferred":false,"id":427630,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mayer, B.","contributorId":84538,"corporation":false,"usgs":true,"family":"Mayer","given":"B.","email":"","affiliations":[],"preferred":false,"id":427635,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kendall, C. 0000-0002-0247-3405","orcid":"https://orcid.org/0000-0002-0247-3405","contributorId":35050,"corporation":false,"usgs":true,"family":"Kendall","given":"C.","affiliations":[],"preferred":false,"id":427631,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"McHale, P.","contributorId":66061,"corporation":false,"usgs":true,"family":"McHale","given":"P.","email":"","affiliations":[],"preferred":false,"id":427632,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Relatively high densities of bullfrog tadpoles and crayfish in razorback sucker spawning areas suggest that these nonnative taxa might pose a threat to the recruitment success of this and other imperiled native fish.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southwestern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1894/0038-4909(2006)51[258:BTRCAR]2.0.CO;2","issn":"00384909","usgsCitation":"Mueller, G., Carpenter, J., and Thornbrugh, D., 2006, Bullfrog tadpole (Rana catesbeiana) and red swamp crayfish (Procambarus clarkii) predation on early life stages of endangered razorback sucker (Xyrauchen texanus): Southwestern Naturalist, v. 51, no. 2, p. 258-261, https://doi.org/10.1894/0038-4909(2006)51[258:BTRCAR]2.0.CO;2.","startPage":"258","endPage":"261","numberOfPages":"4","costCenters":[],"links":[{"id":477451,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1894/0038-4909(2006)51[258:btrcar]2.0.co;2","text":"Publisher Index Page"},{"id":211957,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1894/0038-4909(2006)51[258:BTRCAR]2.0.CO;2"},{"id":239347,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"51","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f2b1e4b0c8380cd4b2e0","contributors":{"authors":[{"text":"Mueller, G.A.","contributorId":9205,"corporation":false,"usgs":true,"family":"Mueller","given":"G.A.","email":"","affiliations":[],"preferred":false,"id":427539,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carpenter, J.","contributorId":102017,"corporation":false,"usgs":true,"family":"Carpenter","given":"J.","affiliations":[],"preferred":false,"id":427541,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thornbrugh, D.","contributorId":95685,"corporation":false,"usgs":true,"family":"Thornbrugh","given":"D.","affiliations":[],"preferred":false,"id":427540,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These new data, bolstered by a comparison with published proxy records, point to a long-term increasing trend in drift ice input into the North Atlantic from 6 to 5 ka toward the present day at sites influenced by the cold east Greenland Current. This feature reflects the late Holocene Neoglacial or cooling period recorded in ice cores and further terrestrial archives on Greenland. In contrast, a decrease in drift ice during the same period is recorded at sites underlying the North Atlantic Drift, which may reflect a warming of this region. The results document that Holocene changes in iceberg rafting and sea ice advection did not occur uniformly across the North Atlantic. Centennial-scale climate variability in the North Atlantic region over the last ???4 kyr is linked to the observed changes in drift ice input. Increased drift ice may have played a role in the increase of cold intervals during the late Holocene, e.g., the Little Ice Age cooling.
