This process may contribute to the formation of nutrient-rich tree islands within the expansive oligotrophic marshes of the Everglades (Florida, United States). This study presents hydrogeochemical data indicating that tree root water uptake is a primary driver of groundwater ion accumulation across one of these islands. Sap flow, soil moisture, water level, water chemistry, and rainfall were measured to identify the relationships between climate, transpiration, and groundwater uptake by phreatophytes and to examine the effect this uptake has on groundwater chemistry and mineral formation in three woody plant communities of differing elevations. During the dry season, trees relied more on groundwater for transpiration, which led to a depressed water table and the advective movement of groundwater and dissolved ions, including phosphorus, from the surrounding marsh towards the centre of the island. Ion exclusion during root water uptake led to elevated concentrations of all major dissolved ions in the tree island groundwater compared with the adjacent marsh. Groundwater was predominately supersaturated with respect to aragonite and calcite in the lower-elevation woody communities, indicating the potential for soil formation. Elevated groundwater phosphorous concentrations detected in the highest-elevation woody community were associated with the leaching of inorganic sediments (i.e. hydroxyapatite) in the vadose zone. Understanding the complex feedback mechanisms regulating plant/groundwater/surface water interactions, nutrient dynamics, and potential soil formation is necessary to manage and restore patterned wetlands such as the Everglades.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecohydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/eco.1394","usgsCitation":"Sullivan, P.L., Engel, V.C., Ross, M.S., and Price, R.M., 2013, The influence of vegetation on the hydrodynamics and geomorphology of a tree island in Everglades National Park (Florida, United States): Ecohydrology, v. 7, no. 2, p. 727-744, https://doi.org/10.1002/eco.1394.","productDescription":"18 p.","startPage":"727","endPage":"744","ipdsId":"IP-039164","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":279853,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279852,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/eco.1394"}],"country":"United States","state":"Florida","otherGeospatial":"Everglades National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.5205,24.851 ], [ -81.5205,25.8915 ], [ -80.3887,25.8915 ], [ -80.3887,24.851 ], [ -81.5205,24.851 ] ] ] } } ] }","volume":"7","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-06-10","publicationStatus":"PW","scienceBaseUri":"5295d12be4b0becc369c8c9f","contributors":{"authors":[{"text":"Sullivan, Pamela L.","contributorId":107605,"corporation":false,"usgs":true,"family":"Sullivan","given":"Pamela","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":486864,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Engel, Victor C. 0000-0002-3858-7308 vengel@usgs.gov","orcid":"https://orcid.org/0000-0002-3858-7308","contributorId":2329,"corporation":false,"usgs":true,"family":"Engel","given":"Victor","email":"vengel@usgs.gov","middleInitial":"C.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":true,"id":486861,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ross, Michael S.","contributorId":45406,"corporation":false,"usgs":true,"family":"Ross","given":"Michael","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":486862,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Price, Rene M.","contributorId":52880,"corporation":false,"usgs":true,"family":"Price","given":"Rene","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":486863,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We hypothesized a decrease in the magnitude of C mineralization over the summer associated with changing flowpaths and decreasing hydrologic connectivity, organic matter lability, and nitrogen (N) availability. Conservative tracers were used to partition C and N loss between catchment export and biogeochemical processing. Coupling tracers with tributary and porewater chemistry indicated C and N cycling in soil flowpaths, with an exponential decrease over the summer. Nitrate was primarily reduced in hillslope flowpaths and the lack of N reaching the stream appeared to limit C mineralization. Stream export accounted for the greatest loss of C, removing 247 and 113 mol hr</span><sup>−1</sup><span>&nbsp;in the early and late summer, respectively. Reactivity was related to hydrologic connectivity between the soils and stream, which was greatest early in the summer and following a large flood. While a warming climate may increase storage potential in thawed soils, the early‐season flush of labile material and late‐season runoff through mineral flowpaths may maintain high C export rates. Therefore, we highlight physical export as a dominant cause of aqueous C loss from silty catchments as the Arctic continues to thaw.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/jgrg.20058","usgsCitation":"Koch, J.C., Runkel, R.L., Striegl, R.G., and McKnight, D.M., 2013, Hydrologic controls on the transport and cycling of carbon and nitrogen in a boreal catchment underlain by continuous permafrost: Journal of Geophysical Research G: Biogeosciences, v. 118, no. 2, p. 698-712, https://doi.org/10.1002/jgrg.20058.","productDescription":"15 p.","startPage":"698","endPage":"712","ipdsId":"IP-045136","costCenters":[{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true},{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":473784,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/jgrg.20058","text":"Publisher Index Page"},{"id":356005,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"118","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-05-13","publicationStatus":"PW","scienceBaseUri":"5b6fd314e4b0f5d57878ed5e","contributors":{"authors":[{"text":"Koch, Joshua C. 0000-0001-7180-6982 jkoch@usgs.gov","orcid":"https://orcid.org/0000-0001-7180-6982","contributorId":202532,"corporation":false,"usgs":true,"family":"Koch","given":"Joshua","email":"jkoch@usgs.gov","middleInitial":"C.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":741067,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Runkel, Robert L. 0000-0003-3220-481X runkel@usgs.gov","orcid":"https://orcid.org/0000-0003-3220-481X","contributorId":685,"corporation":false,"usgs":true,"family":"Runkel","given":"Robert","email":"runkel@usgs.gov","middleInitial":"L.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":741068,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Striegl, Robert G. 0000-0002-8251-4659 rstriegl@usgs.gov","orcid":"https://orcid.org/0000-0002-8251-4659","contributorId":1630,"corporation":false,"usgs":true,"family":"Striegl","given":"Robert","email":"rstriegl@usgs.gov","middleInitial":"G.","affiliations":[{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":false,"id":741069,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McKnight, Diane M.","contributorId":59773,"corporation":false,"usgs":false,"family":"McKnight","given":"Diane","email":"","middleInitial":"M.","affiliations":[{"id":16833,"text":"INSTAAR, University of Colorado","active":true,"usgs":false}],"preferred":false,"id":741070,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Large dams also may indirectly alter these assemblages by changing the food resources available to support macroinvertebrate production. We examined the diets of the 4 most common macroinvertebrate taxa in the Colorado River through Glen and Grand Canyons, seasonally, at 6 sites for 2.5 y. We compared macroinvertebrate diet composition to the composition of epilithon (rock and cliff faces) communities and suspended organic seston to evaluate the degree to which macroinvertebrate diets tracked downstream changes in resource availability. Diets contained greater proportions of algal resources in the tailwater of Glen Canyon Dam and more terrestrial-based resources at sites downstream of the 1st major tributary. As predicted, macroinvertebrate diets tracked turbidity-driven changes in resource availability, and river turbidity partially explained variability in macroinvertebrate diets. The relative proportions of resources assimilated by macroinvertebrates ranged from dominance by algae to terrestrial-based resources, despite greater assimilation efficiencies for algal than terrestrial C. Terrestrial resources were most important during high turbidity conditions, which occurred during the late-summer monsoon season (July–October) when tributaries contributed large amounts of organic matter to the mainstem and suspended sediments reduced algal production. Macroinvertebrate diets were influenced by seasonal changes in tributary inputs and turbidity, a result suggesting macroinvertebrate diets in regulated rivers may be temporally dynamic and driven by tributary inputs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for Freshwater Science","doi":"10.1899/12-088.1","usgsCitation":"Wellard Kelly, H.A., Rosi-Marshall, E.J., Kennedy, T., Hall, R., Cross, W.F., and Baxter, C., 2013, Macroinvertebrate diets reflect tributary inputs and turbidity-driven changes in food availability in the Colorado River downstream of Glen Canyon Dam: Freshwater Science, v. 32, no. 2, p. 397-410, https://doi.org/10.1899/12-088.1.","productDescription":"14 p.","startPage":"397","endPage":"410","numberOfPages":"14","ipdsId":"IP-033489","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":287566,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":287565,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1899/12-088.1"}],"country":"United States","state":"Arizona","otherGeospatial":"Colorado River;Glen Canyon;Grand Canyon","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.0,35.5 ], [ -114.0,37.5 ], [ -111.0,37.5 ], [ -111.0,35.5 ], [ -114.0,35.5 ] ] ] } } ] }","volume":"32","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53805249e4b0826cd501674c","contributors":{"authors":[{"text":"Wellard Kelly, Holly A.","contributorId":72115,"corporation":false,"usgs":true,"family":"Wellard Kelly","given":"Holly","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":493942,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rosi-Marshall, Emma J.","contributorId":17722,"corporation":false,"usgs":true,"family":"Rosi-Marshall","given":"Emma","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":493938,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kennedy, Theodore A. 0000-0003-3477-3629","orcid":"https://orcid.org/0000-0003-3477-3629","contributorId":50227,"corporation":false,"usgs":true,"family":"Kennedy","given":"Theodore A.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":493940,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hall, Robert O.

Wildfire prediction in the south-western United States is of specific concern because of the increasing prevalence and severe effects of fire on desert shrublands and the current lack of accurate fire prediction tools. We developed a fire risk model to predict fire occurrence in a north-eastern Mojave Desert landscape. First we developed a spatial model using remote sensing data to predict fuel loads based on field estimates of fuels. We then modelled fire risk (interactions of fuel characteristics and environmental conditions conducive to wildfire) using satellite imagery, our model of fuel loads, and spatial data on ignition potential (lightning strikes and distance to roads), topography (elevation and aspect) and climate (maximum and minimum temperatures).

The explosive activity triggered PDCs to the north and northeast, which felled modest patches of forest as far as 2 km from the caldera rim.  Felled trees pointing in the down-current direction dominate the disturbance zones.  The PDC on the north flank of Chaitén left a decimeters-thick, bipartite deposit having a basal layer of poorly sorted, fines-depleted pumice-and-lithic coarse ash and lapilli, which transitions abruptly to fines-enriched pumice-and-lithic coarse ash.  The deposit contains fragments of mostly uncharred organics near its base; vegetation protruding above the deposit is uncharred.  The nature of the forest disturbance and deposit characteristics suggest the PDC was dilute, of relatively low temperature (<200°C), and to first approximation had a dynamic pressure of about 2-4 kPa and velocity of about 30-40 ms<sup>-1</sup>.  It was formed by directionally focused explosions throughout the volcano's prehistoric, intracaldera lava dome.  Dilute, low-temperature PDCs that exited the caldera over a low point on the east-southeast caldera rim deposited meters-thick fill of stratified beds of pumice-and-lithic coarse ash and lapilli.  They did not fell large trees more than a few hundred of meters from the caldera rim and were thus less energetic than those on the north and northeast flanks.  They likely formed by partial collapses of the margins of vertical eruption columns.  In the Chaitén River valley south of the volcano, several-meter-thick deposits of two block-and-ash flow (BAF) PDCs are preserved.  Both have a coarse ash matrix that supports blocks and lapilli predominantly of lithic rhyolite dome rock, minor obsidian, and local bedrock.  One deposit was emplaced by a BAF that traveled an undetermined distance downvalley between June and November 2008, apparently triggered by partial collapse of a newly effused lava dome on that started growing on 12 May.  A second, and larger, BAF related to another collapse of the new lava dome on 19 February 2009 traveled to within 3 km of the village of Chaitén, 10 km downstream of the volcano.  It deposited as much as 8-10 m of diamict having sedimentary characteristics very similar to the previous BAF deposit.  Charred trees locally encased within the BAD deposits suggest that the flows were of moderate temperature, perhaps as much as 300°C.  Erosion of the BAD deposits filling the Chaitén River channel has delivered substantial sediment loads downstream, contributing to channel instability and challenged river management.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Andean Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Servicio Nacional de Geología y Minería","publisherLocation":"Santiago, Chile","doi":"10.5027/andgeoV40n2-a09","usgsCitation":"Major, J.J., Pierson, T.C., Hoblitt, R.P., and Moreno, H., 2013, Pyroclastic density currents associated with the 2008-2009 eruption of Chaitén Volcano (Chile): forest disturbances, deposits, and dynamics: Andean Geology, v. 40, no. 2, p. 324-358, https://doi.org/10.5027/andgeoV40n2-a09.","productDescription":"35 p.","startPage":"324","endPage":"358","numberOfPages":"35","costCenters":[],"links":[{"id":473787,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5027/andgeov40n2-a09","text":"Publisher Index Page"},{"id":291185,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291182,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5027/andgeoV40n2-a09"}],"country":"Chile","city":"Chait�n","otherGeospatial":"Chait�n Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -72.902119,-42.963783 ], [ -72.902119,-42.70194 ], [ -72.389881,-42.70194 ], [ -72.389881,-42.963783 ], [ -72.902119,-42.963783 ] ] ] } } ] }","volume":"40","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-05-30","publicationStatus":"PW","scienceBaseUri":"57f7f2dde4b0bc0bec0a063c","contributors":{"authors":[{"text":"Major, Jon J. 0000-0003-2449-4466 jjmajor@usgs.gov","orcid":"https://orcid.org/0000-0003-2449-4466","contributorId":439,"corporation":false,"usgs":true,"family":"Major","given":"Jon","email":"jjmajor@usgs.gov","middleInitial":"J.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":496763,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pierson, Thomas C. 0000-0001-9002-4273 tpierson@usgs.gov","orcid":"https://orcid.org/0000-0001-9002-4273","contributorId":2498,"corporation":false,"usgs":true,"family":"Pierson","given":"Thomas","email":"tpierson@usgs.gov","middleInitial":"C.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":496765,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hoblitt, Richard P. rhoblitt@usgs.gov","contributorId":1937,"corporation":false,"usgs":true,"family":"Hoblitt","given":"Richard","email":"rhoblitt@usgs.gov","middleInitial":"P.","affiliations":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":496764,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moreno, Hugo","contributorId":20232,"corporation":false,"usgs":true,"family":"Moreno","given":"Hugo","email":"","affiliations":[],"preferred":false,"id":496766,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We describe the capabilities of this new monitoring tool and present data captured during the Redoubt eruption. The MiniMax 250-C (MM-250C) radar detected seventeen of the nineteen largest explosive events between March 23 and April 4, 2009. Sixteen of these events reached the stratosphere (above 10 km) within 2–5 min of explosion onset. High column and proximal cloud reflectivity values (50 to 60 dBZ) were observed from many of these events, and were likely due to the formation of mm-sized accretionary tephra-ice pellets. Reflectivity data suggest that these pellets formed within the first few minutes of explosion onset. Rapid sedimentation of the mm-sized pellets was observed as a decrease in maximum detection cloud height. The volcanic cloud from the April 4 explosive event showed lower reflectivity values, due to finer particle sizes (related to dome collapse and related pyroclastic flows) and lack of significant pellet formation. Eruption durations determined by the radar were within a factor of two compared to seismic and pressure-sensor derived estimates, and were not well correlated. Ash dispersion observed by the radar was primarily in the upper troposphere below 10 km, but satellite observations indicate the presence of volcanogenic clouds in the stratosphere. This study suggests that radar is a valuable complement to traditional seismic and satellite monitoring of explosive eruptions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier Science","publisherLocation":"Netherlands","doi":"10.1016/j.jvolgeores.2012.11.004","usgsCitation":"Schneider, D.J., and Hoblitt, R.P., 2013, Doppler weather radar observations of the 2009 eruption of Redoubt Volcano, Alaska: Journal of Volcanology and Geothermal Research, v. 259, p. 133-144, https://doi.org/10.1016/j.jvolgeores.2012.11.004.","productDescription":"12 p.","startPage":"133","endPage":"144","numberOfPages":"12","costCenters":[],"links":[{"id":291173,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291172,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jvolgeores.2012.11.004"}],"country":"United States","state":"Alaska","otherGeospatial":"Redoubt Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -154.792,59.774 ], [ -154.792,61.1813 ], [ -150.6941,61.1813 ], [ -150.6941,59.774 ], [ -154.792,59.774 ] ] ] } } ] }","volume":"259","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f2dde4b0bc0bec0a063e","contributors":{"authors":[{"text":"Schneider, David J. 0000-0001-9092-1054 djschneider@usgs.gov","orcid":"https://orcid.org/0000-0001-9092-1054","contributorId":633,"corporation":false,"usgs":true,"family":"Schneider","given":"David","email":"djschneider@usgs.gov","middleInitial":"J.","affiliations":[{"id":121,"text":"Alaska Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":496750,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hoblitt, Richard P. rhoblitt@usgs.gov","contributorId":1937,"corporation":false,"usgs":true,"family":"Hoblitt","given":"Richard","email":"rhoblitt@usgs.gov","middleInitial":"P.","affiliations":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":496751,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study is the first of its kind to assemble, reprocess, describe, and disseminate a georeferenced U.S. database providing a long-term, detailed characterization of flash flooding in terms of spatiotemporal behavior and specificity of impacts. The database is composed of three primary sources: 1) the entire archive of automated discharge observations from the U.S. Geological Survey that has been reprocessed to describe individual flooding events, 2) flash-flooding reports collected by the National Weather Service from 2006 to the present, and 3) witness reports obtained directly from the public in the Severe Hazards Analysis and Verification Experiment during the summers 2008–10. Each observational data source has limitations; a major asset of the unified flash flood database is its collation of relevant information from a variety of sources that is now readily available to the community in common formats. It is anticipated that this database will be used for many diverse purposes, such as evaluating tools to predict flash flooding, characterizing seasonal and regional trends, and improving understanding of dominant flood-producing processes.

To investigate the role of soil-surface water interactions in recovery from acidification, the first regional survey to directly relate soil chemistry to stream chemistry during high flow was implemented in a 4144-km<sup>2</sup> area of the Catskill region of New York, where acidic deposition levels are among the highest in the East.</p><p>More than 40% of 95 streams sampled in the southern Catskill Mountains were determined to be acidified and had inorganic monomeric aluminum concentrations that exceeded a threshold that is toxic to aquatic biota. More than 80% likely exceeded this threshold during the highest flows, but less than 10% of more than 100 streams sampled were acidified in the northwestern portion of the region. Median Oa horizon soil base saturation ranged from 50% to 80% at 200 sites across the region, but median base saturation in the upper 10 cm of the B horizon was less than 20% across the region and was only 2% in the southern area. Aluminum is likely to be interfering with root uptake of calcium in the mineral horizon in approximately half the sampled watersheds. Stream chemistry was highly variable over the Catskill region and, therefore, did not always reflect the calcium depletion of the B horizon that our sampling suggested was nearly ubiquitous throughout the region.

Hydropeaking flow regimes for electrical power production inundate areas that create temporary suitable habitat for fish that may be rapidly drained. Robust redhorse <i>Moxostoma robustum</i>, an imperiled, rare fish species, uses such temporary habitats to spawn, but when power generation ceases, these areas are dewatered until the next pulse of water is released. We experimentally simulated the effects of dewatering periods on the survival of robust redhorse eggs and larvae in the laboratory. Robust redhorse eggs were placed in gravel in eyeing-hatching jars (three jars per treatment) and subjected to one of four dewatering periods (6, 12, 24 and 48 h), followed by 12 h of inundation for each treatment, and a control treatment was never dewatered. Egg desiccation was observed in some eggs in the 24- and 48-h treatments after one dewatering period. For all treatments except the control, the subsequent dewatering period after eggs hatched was lethal. Larval emergence for the control treatment was observed on day 5 post-hatching and continued until the end of the experiment (day 21). Larval survival was significantly different between the control and all dewatering treatments for individuals in the gravel. These findings support the need for hydropower facilities to set minimum flows to maintain inundation of spawning areas for robust redhorse and other species to reduce dewatering mortality.</p>","language":"English","publisher":"John Wiley & Sons","publisherLocation":"Chichester, West Sussex, UK","doi":"10.1002/rra.2561","collaboration":"State Wildlife Grant through the North Carolina Wildlife Resources Commission; Progress Energy, North Carolina State University; North Carolina Wildlife Resources Commission; US Fish and Wildlife Service; Wildlife Management Institute","usgsCitation":"Fisk, J.M., Kwak, T.J., Heise, R.J., and Sessions, F.W., 2013, Redd dewatering effects on hatching and larval survival of the robust redhorse: River Research and Applications, v. 29, no. 5, p. 574-581, https://doi.org/10.1002/rra.2561.","productDescription":"8 p.","startPage":"574","endPage":"581","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-031549","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":301370,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"5","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2012-01-31","publicationStatus":"PW","scienceBaseUri":"55853d56e4b023124e8f5b37","contributors":{"authors":[{"text":"Fisk, J.

The \nCalifornia Floristic Province is the largest and most important geographic floristic unit in \nCalifornia and extends from the Klamath Mountains of southwestern Oregon to the northwestern \nportion of Baja California (Hickman 1993). The Sierra Nevada, one of six regions that make up \nthe California Floristic Province, covers nearly 20% of the land in California yet contains over \n50% of its flora. Within the Sierra Nevada, the southern Sierra supports more Sierran endemic \nand rare plant taxa than the central and northern portions of the region (Shevock 1996). Sequoia \nand Kings Canyon National Parks (SEKI) encompass roughly 20% of the southern Sierra \nNevada region. The parks overlap three floristic subregions (central Sierra Nevada High, \nsouthern Sierra Nevada High, and southern Sierra Nevada Foothills), and border the Great Basin \nFloristic Province.</p>\n<br>\n<p>The parks support a rich and diverse vascular flora composed of over 1,560 taxa. Of these, 150 \ntaxa are identified as having special status. The term special status is applied here to include \ntaxa that are state or federally listed, rare in California, or at risk because they have a limited \ndistribution. Only one species from these parks is listed under the state or federal Endangered \nSpecies Acts (<i>Carex tompkinsii</i>, Tompkins‘ sedge, is listed as a rare species under the California \nEndangered Species Act), and one species is under review for federal endangered listing (<i>Pinus \nalbicaulis</i>, whitebark pine). However, an absence of threatened and endangered species recognized \nby Endangered Species Acts is not equivalent to an absence of species at risk. There are 83 plant \ntaxa documented as occurring in SEKI that are considered imperiled or vulnerable in the state by the \nCalifornia Department of Fish and Game‘s California Natural Diversity Database (CNDDB \n2010a). There are an additional 66 taxa not formally listed by CNDDB that are recognized as \nhaving special status because their distribution is restricted to the Sierra Nevada. Special status \nplants are distributed throughout the two parks and inhabit a wide range of environments along the \nlength of the elevation gradient that characterizes these parks.</p>\n<br>\n<p>Ideally, we would assess the condition (status and trends) of each of the taxa on the SEKI special \nstatus plant list, documenting current population sizes, demographic rates and demographic \ntrends. We would also hope to quantify the effects of individual stressors on each species based \non existing monitoring and research. However, no data are available for most of the species on \nthe special status plant list. For those few species (12 herbaceous species and two tree species) \nfor which we possess some change over time information, the data are not adequate to make a \ncompetent assessment. Note that we have not explored the tree demographic information in any \ndetail, as is covered in the NRCA Intact Forest/Five Needle Pines and Sequoia chapters. In \ngeneral, we are unable to present an ‗integrity‘ metric for special status species in the parks, \nsince the data to quantify the condition of each species in such a manner is not available.</p>\n<br>\n<p>In contrast, the park does possess substantial data describing biodiversity in the parks. Therefore, \nour analysis focuses on describing the distribution and rarity of special status plants within the \nparks, with a particular focus on assessing the spatial distribution of species richness. We hope \nthat such information will prove useful to park managers in determining which areas in the parks \nmerit the most attention (for example in developing monitoring protocols). We also assess \npotential vulnerability of special status species to the stressors chosen by the NRCA working \ngroup, using both park data and available literature.</p>\n<br>\n<p>As a first step, we spent considerable effort updating and refining the criteria for the special \nstatus plant list, as this list defines which taxa are considered in our assessment. Observation data \nof these species was then compiled from all known sources in order to provide a comprehensive \nview of where special status plants have been documented and, ultimately, to enable the most \ninformed determinations of areas in the parks that potentially support the highest number of rare \nand endemic taxa. These ‗hot spot‘ analyses are presented by geographic region, vegetation type \nand elevation.</p>\n<br>\n<p>For these and other analyses presented in this report, we place more focus on summarizing \nfindings for the herbaceous and shrub special status taxa than on special status trees. The trees \nwhich qualify as special status are the focus of other NRCA chapters, including Giant Sequoia \nand Intact Forests/Five-needle Pines. We do, however, present their mapped distributions and \nprovide overviews of research related to the special status tree taxa in the Stressors section of this \nreport.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"A natural resource condition assessment for Sequoia and Kings Canyon National Parks","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Park Service","publisherLocation":"Fort Collins, CO","usgsCitation":"Huber, A., Das, A., Wenk, R., and Haultain, S., 2013, A natural resource condition assessment for Sequoia and Kings Canyon National Parks: Appendix 14: plants of conservation concern: Natural Resource Report NPS/SEKI/NRR--2013/665.14, ix, 94 p.","productDescription":"ix, 94 p.","numberOfPages":"108","ipdsId":"IP-035065","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":294339,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294338,"type":{"id":15,"text":"Index Page"},"url":"https://irma.nps.gov/App/Reference/Profile/2195708"}],"country":"United States","state":"California","otherGeospatial":"Kings Canyon National Park;Sequoia National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.983208,36.118448 ], [ -118.983208,37.237613 ], [ -118.020777,37.237613 ], [ -118.020777,36.118448 ], [ -118.983208,36.118448 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5422bb07e4b08312ac7ceeb7","contributors":{"authors":[{"text":"Huber, Ann","contributorId":16335,"corporation":false,"usgs":true,"family":"Huber","given":"Ann","email":"","affiliations":[],"preferred":false,"id":501083,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Das, Adrian","contributorId":73935,"corporation":false,"usgs":true,"family":"Das","given":"Adrian","affiliations":[],"preferred":false,"id":501084,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wenk, Rebecca","contributorId":95403,"corporation":false,"usgs":true,"family":"Wenk","given":"Rebecca","email":"","affiliations":[],"preferred":false,"id":501085,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Haultain, Sylvia","contributorId":107761,"corporation":false,"usgs":true,"family":"Haultain","given":"Sylvia","affiliations":[],"preferred":false,"id":501086,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Overlap between <sup>40</sup>Ar/<sup>39</sup>Ar ages for the youngest intracanyon basalt flow and <sup>10</sup>Be surface exposure dating of downstream terrace surfaces suggests widespread channel incision during a prominent outburst flood through the Little Lake channel at ca. 64 ka. Older basalt flows flanking the upper and lower canyon margins indicate localization of the Owens River in its current position between 212 ± 14 and 197 ± 11 ka. Coupled with terrestrial light detection and ranging (lidar) and digital topographic measurements of dextral offset, the revised Little Lake chronology indicates average dextral slip rates of at least ∼0.6–0.7 mm/yr and <1.3 mm/yr over intervals ranging from ∼10<sup>4</sup> to 10<sup>5</sup> yr. Despite previous geodetic observations of relatively rapid interseismic strain along the Little Lake fault, we find no evidence for sustained temporal fluctuations in slip rates over multiple earthquake cycles. Instead, our results indicate that accelerated fault loading may be transient over much shorter periods (∼10<sup>1</sup> yr) and perhaps indicative of time-dependent seismic hazard associated with Eastern California shear zone faults.","language":"English","publisher":"Geological Society of America","doi":"10.1130/B30803.1","usgsCitation":"Amos, C.B., Brownlee, S.J., Rood, S.H., Fisher, G.B., Burgmann, R., Renne, P., and Jayko, A.S., 2013, Chronology of tectonic, geomorphic, and volcanic interactions and the tempo of fault slip near Little Lake, California: Geological Society of America Bulletin, v. 125, no. 7-8, p. 1187-1202, https://doi.org/10.1130/B30803.1.","productDescription":"15 p.","startPage":"1187","endPage":"1202","onlineOnly":"Y","ipdsId":"IP-044875","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":278980,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"Little Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.926741,35.916614 ], [ -117.926741,35.956614 ], [ -117.886741,35.956614 ], [ -117.886741,35.916614 ], [ -117.926741,35.916614 ] ] ] } } ] }","volume":"125","issue":"7-8","noUsgsAuthors":false,"publicationDate":"2013-06-07","publicationStatus":"PW","scienceBaseUri":"527e5867e4b02d2057dd95c5","contributors":{"authors":[{"text":"Amos, Colin B.","contributorId":62127,"corporation":false,"usgs":true,"family":"Amos","given":"Colin","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":485784,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brownlee, Sarah J.","contributorId":72697,"corporation":false,"usgs":true,"family":"Brownlee","given":"Sarah","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":485785,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rood, Sylan H.","contributorId":17906,"corporation":false,"usgs":true,"family":"Rood","given":"Sylan","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":485781,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fisher, G.

We evaluated the association of a suite of abiotic factors (stream width, elevation, gradient, large woody debris density, pool density, August mean stream temperature, reach surface area) with the occurrence (presence or absence) of bull trout and westslope cutthroat trout in 79 stream reaches in five sub-drainages containing glacial lakes. We modeled the occurrence of each species using logistic regression and evaluated competing models using an information theoretic approach. Westslope cutthroat trout were widely distributed (47 of 79 reaches), and there appeared to be no restrictions on their distribution other than physical barriers. Westslope cutthroat trout were most commonly found in relatively warm reaches downstream of lakes and in headwater reaches with large amounts of large woody debris and abundant pools. By contrast, bull trout were infrequently detected (10 of 79 reaches), with 7 of the 10 (70%) detections in sub-drainages that have not been compromised by non-native lake trout (</span><i>S. namaycush</i><span>). Bull trout were most often found in cold, low-gradient reaches upstream of glacial lakes. Our results indicate that complex stream habitats in sub-drainages free of non-native species are important to the persistence of native salmonids in western Glacier National Park. Results from this study may help managers monitor and protect important habitats and populations, inform conservation and recovery programs, and guide non-native species suppression efforts in Glacier

The World Bank, USAID, and other international donor agencies began making efforts to mainstream disaster risk reduction in countries whose population and economies were heavily dependent on rain-fed agriculture. This approach has more significance in light of the increasing climatic hazard patterns and the climate scenarios projected for different hazard prone countries in the world. The Famine Early Warning System Network (FEWS NET) has been monitoring the food security issues in the sub-Saharan Africa, Asia and in Haiti. FEWS NET monitors the rainfall and moisture availability conditions with the help of NOAA RFE2 data for deriving food security status in Africa. This paper highlights the efforts in using satellite estimated rainfall inputs to develop drought vulnerability models in the drought prone areas in Malawi. The satellite RFE2 based SPI corresponding to the critical tasseling and silking phases (in the months of January, February, and March) were statistically regressed with drought-induced yield losses at the district level. The analysis has shown that the drought conditions in February and early March lead to most damage to maize yields in this region. The district-wise vulnerabilities to drought were upscaled to obtain a regional maize vulnerability model for southern Malawi. The results would help in establishing an early monitoring mechanism for drought impact assessment, give the decision makers additional time to assess seasonal outcomes, and identify potential food-related hazards in Malawi.</p>","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam","doi":"10.1016/j.ijdrr.2013.02.001","usgsCitation":"Funk, C.C., Verdin, J., Chavula, A., Gregory J.

We present a simple but robust method that uses remotely sensed thermal data and model-assimilated weather fields to produce ET for the contiguous United States (CONUS) at monthly and seasonal time scales. The method is based on the Simplified Surface Energy Balance (SSEB) model, which is now parameterized for operational applications, renamed as SSEBop. The innovative aspect of the SSEBop is that it uses predefined boundary conditions that are unique to each pixel for the \"hot\" and \"cold\" reference conditions. The SSEBop model was used for computing ET for 12 years (2000-2011) using the MODIS and Global Data Assimilation System (GDAS) data streams. SSEBop ET results compared reasonably well with monthly eddy covariance ET data explaining 64% of the observed variability across diverse ecosystems in the CONUS during 2005. Twelve annual ET anomalies (2000-2011) depicted the spatial extent and severity of the commonly known drought years in the CONUS.

The devices have become smaller, more reliable, and more capable (Printz 2004; Wilson and Gifford 2005; Metcalfe et al. 2012). Compared with externally mounted devices, implanted devices are largely invisible to external viewers such as tourists and predators; exist in a physically protected, thermally stable environment in mammals and birds; and greatly reduce drag and risk of entanglement. An implanted animal does not outgrow its device or attachment method as can happen with collars and harnesses, which allows young animals to be more safely equipped. However, compared with mounting external devices, implantation requires greater technical ability to perform the necessary anesthesia, analgesia, and surgery.</p>\n<br/>\n<p>More than 83% of publications in the 1990s that used radiotelemetry on animals assumed that there were no adverse effects on the animal (Godfrey and Bryant 2003). It is likely that some studies using implanted electronic devices have not been published due to a high level of unexpected mortality or to aberrant behavior or disappearance of the implanted animals, a phenomenon known as the “file drawer” problem (Rosenthal 1979; Scargle 2000). The near absence of such studies from the published record may be providing a false sense of security that procedures being used are more innocuous than they actually are. Similarly, authors sometimes state that it was unlikely that device implantation was problematic because study animals appeared to behave normally, or authors state that previous investigators used the same technique and saw no problems. Such statements are suppositions if no supporting data are provided or if the animals were equipped because there was no other way to follow their activity. Moreover, such suppositions ignore other adverse effects that affect behavior indirectly, and animals often mask the signs of infection to avoid attracting predators (Wobeser 2006).</p>\n<br/>\n<p>Guidance specific to sterilization of electronic devices for implantation is limited in the wildlife record (Burger et al. 1994; Mulcahy 2003). Few biologists have been formally trained in aseptic technique, but most biologists know that electronic devices should be treated in some way to reduce the chance for infection of the host animal by bacteria, viruses, parasites, and fungi. Most biologists (73%) who implant devices into fishes believe aseptic techniques are important (Wagner and Cooke 2005). However, I maintain that many biologists find it difficult to place the concept of asepsis into practice in their work because of confusion about what constitutes aseptic technique, a lack of surgical knowledge and training, the perception of increased costs, or the belief that aseptic surgeries are impractical or unnecessary for their application. Some have even argued that, while compromising surgical techniques in the field might result in complications or mortalities, the money saved would allow for a compensatory increase in sample size (Anderson and Talcott 2006).</p>\n<br/>\n<p>In this paper I define aseptic surgical techniques, document the legal and professional guidance for performing aseptic surgeries on wild animals, and present options for sterilizing electronic devices and surgical instruments for field use.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Fish and Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish and Wildlife Service","doi":"10.3996/092012-JFWM-080","usgsCitation":"Mulcahy, D.M., 2013, Legal, ethical, and procedural bases for the use of aseptic techniques to implant electronic devices: Journal of Fish and Wildlife Management, v. 4, no. 1, p. 211-219, https://doi.org/10.3996/092012-JFWM-080.","productDescription":"9 p.","startPage":"211","endPage":"219","numberOfPages":"9","ipdsId":"IP-030295","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":473790,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3996/092012-jfwm-080","text":"Publisher Index Page"},{"id":287080,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":287070,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3996/092012-JFWM-080"}],"volume":"4","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53733efbe4b049706127890e","contributors":{"authors":[{"text":"Mulcahy, Daniel M. dmulcahy@usgs.gov","contributorId":3102,"corporation":false,"usgs":true,"family":"Mulcahy","given":"Daniel","email":"dmulcahy@usgs.gov","middleInitial":"M.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":493666,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Current distributions were modelled using climate, geology, soils, land use, landform and flow variables thought to be important to lotic crayfish. Potential changes in the distribution were forecast by using models trained on current conditions and projecting onto the landscape predicted under climate-change scenarios. 3.The modelled distribution of the four species closely resembled the perceived distribution of each species but also predicted populations in streams and catchments where they had not previously been collected. Soils, elevation and winter precipitation and temperature most strongly related to current distributions and represented 6587% of the predictive power of the models. Model accuracy was high for all models, and model predictions of new populations were verified through additional field sampling. 4.Current models created using two spatial resolutions (1 and 4.5km2) showed that fine-resolution data more accurately represented current distributions. For three of the four species, the 1-km2 resolution models resulted in more conservative predictions. However, the modelled distributional extent of Orconectes leptogonopodus was similar regardless of data resolution. Field validations indicated 1-km2 resolution models were more accurate than 4.5-km2 resolution models. 5.Future projected (4.5-km2 resolution models) model distributions indicated three of the four endemic species would have truncated ranges with low occurrence probabilities under the low-emission scenario, whereas two of four species would be severely restricted in range under moderatehigh emissions. Discrepancies in the two emission scenarios probably relate to the exclusion of behavioural adaptations from species-distribution models. 6.These model predictions illustrate possible impacts of climate change on narrow-range endemic crayfish populations. The predictions do not account for biotic interactions, migration, local habitat conditions or species adaptation. However, we identified the constraining landscape features acting on these populations that provide a framework for addressing habitat needs at a fine scale and developing targeted and systematic monitoring programmes.</p>","language":"English","publisher":"Blackwell Science","publisherLocation":"Oxford, England","doi":"10.1111/fwb.12109","usgsCitation":"Dyer, J.J., Brewer, S.K., Worthington, T.A., and Bergey, E.A., 2013, The influence of coarse-scale environmental features on current and predicted future distributions of narrow-range endemic crayfish populations: Freshwater Biology, v. 58, no. 6, p. 1071-1088, https://doi.org/10.1111/fwb.12109.","productDescription":"18 p.","startPage":"1071","endPage":"1088","numberOfPages":"18","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-041861","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":300273,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"58","issue":"6","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2013-02-18","publicationStatus":"PW","scienceBaseUri":"5551d2bce4b0a92fa7e93c15","contributors":{"authors":[{"text":"Dyer, Joseph J.","contributorId":140681,"corporation":false,"usgs":false,"family":"Dyer","given":"Joseph","email":"","middleInitial":"J.","affiliations":[{"id":7249,"text":"Oklahoma State University","active":true,"usgs":false}],"preferred":false,"id":546574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brewer, Shannon K. 0000-0002-1537-3921 skbrewer@usgs.gov","orcid":"https://orcid.org/0000-0002-1537-3921","contributorId":2252,"corporation":false,"usgs":true,"family":"Brewer","given":"Shannon","email":"skbrewer@usgs.gov","middleInitial":"K.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":546475,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Worthington, Thomas A.","contributorId":140662,"corporation":false,"usgs":false,"family":"Worthington","given":"Thomas","email":"","middleInitial":"A.","affiliations":[{"id":7249,"text":"Oklahoma State University","active":true,"usgs":false}],"preferred":false,"id":546575,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bergey, Elizabeth A.","contributorId":140682,"corporation":false,"usgs":false,"family":"Bergey","given":"Elizabeth","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":546576,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Although these geophysical processes are important sediment dispersal mechanisms, few distinct geomorphic features on the continental shelf can be attributed to hyperpycnal flows. Here we provide evidence of large depositional features derived from hyperpycnal plumes on the continental shelf of the northern Santa Barbara Channel, California, from the combination of new sonar, lidar, and seismic reflection data. These data reveal lobate fans directly offshore of the mouths of several watersheds known to produce hyperpycnal concentrations of suspended sediment. The fans occur on an upwardly concave section of the shelf where slopes decrease from 0.04 to 0.01, and the location of these fans is consistent with wave- and auto-suspending sediment gravity current theories. Thus, we provide the first documentation that the morphology of sediment deposits on the continental shelf can be dictated by river-generated hyperpycnal flows.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/grl.50488","usgsCitation":"Warrick, J., Simms, A.R., Ritchie, A., Steel, E., Dartnell, P., Conrad, J.E., and Finlayson, D.P., 2013, Hyperpycnal plume-derived fans in the Santa Barbara Channel, California: Geophysical Research Letters, v. 40, no. 10, p. 2081-2086, https://doi.org/10.1002/grl.50488.","productDescription":"6 p.","startPage":"2081","endPage":"2086","ipdsId":"IP-045463","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":473791,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/grl.50488","text":"Publisher Index Page"},{"id":285702,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285653,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/grl.50488"},{"id":285654,"type":{"id":15,"text":"Index Page"},"url":"https://onlinelibrary.wiley.com/doi/10.1002/grl.50488/abstract"}],"country":"United States","state":"California","otherGeospatial":"Santa Barbara Channel","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.15,34.09 ], [ -120.15,34.53 ], [ -119.44,34.53 ], [ -119.44,34.09 ], [ -120.15,34.09 ] ] ] } } ] }","volume":"40","issue":"10","noUsgsAuthors":false,"publicationDate":"2013-05-31","publicationStatus":"PW","scienceBaseUri":"5355947ae4b0120853e8c01a","contributors":{"authors":[{"text":"Warrick, Jonathan A. 0000-0002-0205-3814","orcid":"https://orcid.org/0000-0002-0205-3814","contributorId":48255,"corporation":false,"usgs":true,"family":"Warrick","given":"Jonathan A.","affiliations":[],"preferred":false,"id":492376,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Simms, Alexander R.","contributorId":52887,"corporation":false,"usgs":true,"family":"Simms","given":"Alexander","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":492377,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ritchie, Andy","contributorId":40124,"corporation":false,"usgs":true,"family":"Ritchie","given":"Andy","affiliations":[],"preferred":false,"id":492374,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Steel, Elisabeth","contributorId":47692,"corporation":false,"usgs":true,"family":"Steel","given":"Elisabeth","email":"","affiliations":[],"preferred":false,"id":492375,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dartnell, Pete","contributorId":33412,"corporation":false,"usgs":true,"family":"Dartnell","given":"Pete","email":"","affiliations":[],"preferred":false,"id":492373,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Conrad, James E. 0000-0001-6655-694X jconrad@usgs.gov","orcid":"https://orcid.org/0000-0001-6655-694X","contributorId":2316,"corporation":false,"usgs":true,"family":"Conrad","given":"James","email":"jconrad@usgs.gov","middleInitial":"E.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":492372,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Finlayson, David P. dfinlayson@usgs.gov","contributorId":1381,"corporation":false,"usgs":true,"family":"Finlayson","given":"David","email":"dfinlayson@usgs.gov","middleInitial":"P.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":492371,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

This review covers 703 species representing 16 families and 93 genera, of which 67 species are considered extinct, or possibly extinct, 278 are endangered, 102 are threatened, 73 are vulnerable, 157 are currently stable, and 26 species have uncertain taxonomic status. Of the entire fauna, 74% of gastropods are imperiled (vulnerable, threatened, endangered) or extinct, which exceeds imperilment levels in fishes (39%) and crayfishes (48%) but is similar to that of mussels (72%). Comparison of modern to background extinction rates reveals that gastropods have the highest modern extinction rate yet observed, 9,539 times greater than background rates. Gastropods are highly susceptible to habitat loss and degradation, particularly narrow endemics restricted to a single spring or short stream reaches. Compilation of this review was hampered by a paucity of current distributional information and taxonomic uncertainties. Although research on several fronts including basic biology, physiology, conservation strategies, life history, and ecology are needed, systematics and curation of museum collections and databases coupled with comprehensive status surveys (geographic limits, threat identification) are priorities.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fisheries","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor &

To effectively control the spread of these species, managers must be aware of the multitude of dispersal methods used by the organisms. We investigated the potential for survival through the gut of a migrating fish (blue catfish, <i>Ictalurus furcatus</i>) as a dispersal mechanism for two invasive bivalves: zebra mussel (<i>Driessena polymorpha</i>) and Asian clam (<i>Corbicula fluminea</i>). Blue catfish (N = 62) were sampled over several months from Sooner Lake, Oklahoma, transported to a laboratory and held in individual tanks for 48 h. All fecal material was collected and inspected for live mussels. Survival was significantly related to water temperature in the lake at the time of collection, with no mussels surviving above 21.1 C&deg;, whereas 12 % of zebra mussels (N = 939) and 39 % of Asian clams (N = 408) consumed in cooler water survived gut passage.

Candidate models were evaluated using mixed-model linear regression analyses, with mean basal area increment as the response variable. We then analysed stand-level spatial patterns of competition indices and growth rates (via kriging) to determine if the relationship between these patterns could further elucidate factors influencing tree growth.</p>\n<br/>\n<p>Results: Inter-tree competition clearly affected growth rates, with crown volume being the size metric most strongly influencing the neighbourhood competitive environment. Including neighbour tree mortality weightings in models only slightly improved descriptions of competitive interactions. Although the within-neighbourhood clustering index did not improve model predictions, competition intensity was influenced by the underlying stand-level tree spatial arrangement: stand-level clustering locally intensified competition and reduced tree growth, whereas in the absence of such clustering, inter-tree competition played a lesser role in constraining tree growth.</p>\n<br/>\n<p>Conclusions: Our findings demonstrate that competition continues to influence forest processes and structures in an old-growth system that has not experienced major disturbances for at least two centuries. The finding that the underlying tree spatial pattern influenced the competitive environment suggests caution in interpreting traditional tree competition studies, in which tree spatial patterning is typically not taken into account. Our findings highlight the importance of forest structure – particularly the spatial arrangement of trees – in regulating inter-tree competition and growth in structurally diverse forests, and they provide insight into the causes and consequences of heterogeneity in this old-growth system.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Vegetation Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/jvs.12096","usgsCitation":"Fraver, S., D’Amato, A.W., Bradford, J.B., Jonsson, B.G., Jonsson, M., and Esseen, P., 2013, Tree growth and competition in an old-growth <i>Picea abies</i> forest of boreal Sweden: influence of tree spatial patterning: Journal of Vegetation Science, v. 25, no. 2, p. 374-385, https://doi.org/10.1111/jvs.12096.","productDescription":"12 p.","startPage":"374","endPage":"385","numberOfPages":"12","ipdsId":"IP-042516","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":281044,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277525,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/jvs.12096"}],"country":"Sweden","county":"V�sterbotten County","otherGeospatial":"Gardfj�llet Nature Reserve","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 14.26,63.41 ], [ 14.26,66.34 ], [ 21.62,66.34 ], [ 21.62,63.41 ], [ 14.26,63.41 ] ] ] } } ] }","volume":"25","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-06-21","publicationStatus":"PW","scienceBaseUri":"53cd7993e4b0b2908510cec6","contributors":{"authors":[{"text":"Fraver, Shawn","contributorId":91379,"corporation":false,"usgs":false,"family":"Fraver","given":"Shawn","email":"","affiliations":[{"id":7063,"text":"University of Maine","active":true,"usgs":false}],"preferred":false,"id":483874,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"D’Amato, Anthony W.","contributorId":28140,"corporation":false,"usgs":false,"family":"D’Amato","given":"Anthony","email":"","middleInitial":"W.","affiliations":[{"id":6735,"text":"University of Vermont, Rubenstein School of Environment and Natural Resources","active":true,"usgs":false},{"id":13478,"text":"Department of Forest Resources, University of Minnesota, St. Paul, Minnesota (Correspondence to: russellm@umn.edu)","active":true,"usgs":false}],"preferred":false,"id":483871,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bradford, John B. 0000-0001-9257-6303 jbradford@usgs.gov","orcid":"https://orcid.org/0000-0001-9257-6303","contributorId":611,"corporation":false,"usgs":true,"family":"Bradford","given":"John","email":"jbradford@usgs.gov","middleInitial":"B.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":483869,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jonsson, Bengt Gunnar","contributorId":27361,"corporation":false,"usgs":true,"family":"Jonsson","given":"Bengt","email":"","middleInitial":"Gunnar","affiliations":[],"preferred":false,"id":483870,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Jonsson, Mari","contributorId":65003,"corporation":false,"usgs":true,"family":"Jonsson","given":"Mari","email":"","affiliations":[],"preferred":false,"id":483873,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Esseen, Per-Anders","contributorId":54113,"corporation":false,"usgs":true,"family":"Esseen","given":"Per-Anders","email":"","affiliations":[],"preferred":false,"id":483872,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}
