Recent declines in deepwater sculpin abundance and changes in bathymetric distribution may be associated with changes in the deepwater food web of Lake Huron, particularly, decreased abundance of benthic invertebrates such as Diporeia. To assess how deepwater sculpins have responded to recent changes, we examined a fifteen-year time series of spatial and temporal patterns in abundance as well as the diets of fish collected in bottom trawls during fall of 2003, 2004, and 2005. During 1992-2007, deepwater sculpin abundance declined on a lake-wide scale but the decline in abundance at shallower depths and in the southern portion of Lake Huron was more pronounced. Of the 534 fish examined for diet analysis, 97% had food in the stomach. Mysis, Diporeia, and Chironomidae were consumed frequently, while sphaerid clams, ostracods, fish eggs, and small fish were found in only low numbers. We found an inverse relationship between prevalence of Mysis and Diporeia in diets that reflected geographic and temporal trends in abundance of these invertebrates in Lake Huron. Because deepwater sculpins are an important trophic link in offshore benthic food webs, declines in population abundance and changes in distribution may cascade throughout the food web and impede fish community restoration goals.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jglr.2009.05.006","issn":"03801330","usgsCitation":"O’Brien, T.P., Roseman, E., Kiley, C., and Schaeffer, J., 2009, Fall diet and bathymetric distribution of deepwater sculpin (Myoxocephalus thompsonii) in Lake Huron: Journal of Great Lakes Research, v. 35, no. 3, p. 464-472, https://doi.org/10.1016/j.jglr.2009.05.006.","startPage":"464","endPage":"472","numberOfPages":"9","costCenters":[],"links":[{"id":217679,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2009.05.006"},{"id":245639,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0ee5e4b0c8380cd5368d","contributors":{"authors":[{"text":"O’Brien, T.

Fish-eating birds (Forster's and Caspian terns) had the highest Hg concentrations in thier tissues, but concentrations in an invertebrate-foraging shorebird (black-necked stilt) were also elevated. Foraging habitat was important for Hg exposure as illustrated by within-guild differences, where species more associated with marshes and salt ponds had higher concentrations than those more associated with open-bay and tidal mudflats. Importantly, Hg concentrations increased with time spent in the estuary. Surf scoter concentrations tripled over six months, whereas Forster's terns showed an up to 5-fold increase between estuary arrival and breeding. Breeding waterbirds were at elevated risk of Hg-induced reproductive impairment, particularly Forster's terns, in which 48% of breeding birds were at high risk due to their Hg??levels.

We found significant effects that were most pronounced within 300 m of the shore, but extended 3 km inland via coyote scat deposition. The zone within 300 m of the sea had a higher density of vegetation with a distinctly different plant composition. The denser vegetation supported higher abundances of birds and reptiles. Coyotes exhibited spatial and temporal responses to marine subsidies of fish, while birds were likely subsidized by aquatic aerial insects. Top-down control, as well as dietary and habitat preferences, may have resulted in reduced number of ants, beetles, and small mammals near the sea. Species responses to the habitat edge appeared to be associated with life history, as the near shore habitat favored habitat generalists and shore specialists, while inland desert habitat favored many sand and open desert specialists. Ecosystem responses support current theories of allochthonous spatial subsidies and consumer-resource dynamics but were limited in scope, magnitude, and distance.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Arid Environments","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jaridenv.2009.03.002","issn":"01401963","usgsCitation":"Brehme, C., Boarman, W., Hathaway, S., Herring, A., Lyren, L., Mendelsohn, M., Pease, K., Rahn, M., Rochester, C., Stokes, D., Turschak, G., and Fisher, R., 2009, Spatial and temporal patterns across an ecological boundary: Allochthonous effects of a young saltwater lake on a desert ecosystem: Journal of Arid Environments, v. 73, no. 9, p. 811-820, https://doi.org/10.1016/j.jaridenv.2009.03.002.","startPage":"811","endPage":"820","numberOfPages":"10","costCenters":[],"links":[{"id":245671,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217710,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jaridenv.2009.03.002"}],"volume":"73","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b943ee4b08c986b31a967","contributors":{"authors":[{"text":"Brehme, C.S.","contributorId":101210,"corporation":false,"usgs":true,"family":"Brehme","given":"C.S.","affiliations":[],"preferred":false,"id":457617,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boarman, W.I.","contributorId":73523,"corporation":false,"usgs":true,"family":"Boarman","given":"W.I.","email":"","affiliations":[],"preferred":false,"id":457615,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hathaway, S.A.","contributorId":56990,"corporation":false,"usgs":true,"family":"Hathaway","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":457611,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Herring, A.","contributorId":64489,"corporation":false,"usgs":true,"family":"Herring","given":"A.","email":"","affiliations":[],"preferred":false,"id":457614,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lyren, L.","contributorId":59376,"corporation":false,"usgs":true,"family":"Lyren","given":"L.","email":"","affiliations":[],"preferred":false,"id":457613,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mendelsohn, M.","contributorId":59275,"corporation":false,"usgs":true,"family":"Mendelsohn","given":"M.","email":"","affiliations":[],"preferred":false,"id":457612,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Pease, K.","contributorId":30569,"corporation":false,"usgs":true,"family":"Pease","given":"K.","email":"","affiliations":[],"preferred":false,"id":457608,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Rahn, M.","contributorId":48798,"corporation":false,"usgs":true,"family":"Rahn","given":"M.","email":"","affiliations":[],"preferred":false,"id":457609,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Rochester, C.","contributorId":106826,"corporation":false,"usgs":true,"family":"Rochester","given":"C.","email":"","affiliations":[],"preferred":false,"id":457618,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Stokes, D.","contributorId":12402,"corporation":false,"usgs":true,"family":"Stokes","given":"D.","email":"","affiliations":[],"preferred":false,"id":457607,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Turschak, G.","contributorId":94140,"corporation":false,"usgs":true,"family":"Turschak","given":"G.","email":"","affiliations":[],"preferred":false,"id":457616,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Fisher, Robert N. 0000-0002-2956-3240","orcid":"https://orcid.org/0000-0002-2956-3240","contributorId":51675,"corporation":false,"usgs":true,"family":"Fisher","given":"Robert N.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":457610,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}} ,{"id":70036634,"text":"70036634 -

In 2001-2003 and 2002-2003 (Abernathy and Chinook, respectively), 300-500 coastal O. c. clarkii were captured in each tributary by electrofishing and implanted with 23 mm PIT tags. PIT arrays monitored movements from the initiation of tagging through the spring of 2005. Rotary screw traps were also operated on both tributaries. In Abernathy Creek, 28% of tagged individuals were observed through either active capture or passive interrogation. Of these, 32% were identified as migrants and 68% were identified as residents. In the Chinook River, 48% of tagged fish were observed subsequent to tagging; 92% of these fish were migrants and only 8% were resident. In both tributaries, a greater proportion of resident fish were in the upper reaches. The majority of migrants (78-93%) moved the spring following tagging. Migrants leaving at age 2+ years tended to grow faster than those that migrated at age 3+ years or residents.

The subsurface of this reach receives ground water discharge and surface water infiltration due to an altered hydraulic setting resulting from agricultural irrigation. Filtered ground water samples were collected from 30 drive point locations in March, June, and October 2004. Hydrologic processes, described previously, were verified by observations of bromine concentrations; manganese was used to indicate redox conditions. The separate responses of the minor solutes strontium, barium, uranium, and phosphorus to these influences were examined. Correlation and principal component analyses indicate that hydrologic processes dominate the distribution of trace elements in the ground water. Redox conditions appear to be independent of hydrologic processes and account for most of the remaining data variability. With some variability, major processes are consistent in two sampling transects separated by 100 m.

This paper investigates the size distribution of submarine landslides along the U.S. Atlantic continental slope and rise using the size of the landslide source regions (landslide failure scars). Landslide scars along the margin identified in a detailed bathymetric Digital Elevation Model (DEM) have areas that range between 0.89??km2 and 2410??km2 and volumes between 0.002??km3 and 179??km3. The area to volume relationship of these failure scars is almost linear (inverse power-law exponent close to 1), suggesting a fairly uniform failure thickness of a few 10s of meters in each event, with only rare, deep excavating landslides. The cumulative volume distribution of the failure scars is very well described by a log-normal distribution rather than by an inverse power-law, the most commonly used distribution for both subaerial and submarine landslides. A log-normal distribution centered on a volume of 0.86??km3 may indicate that landslides preferentially mobilize a moderate amount of material (on the order of 1??km3), rather than large landslides or very small ones. Alternatively, the log-normal distribution may reflect an inverse power law distribution modified by a size-dependent probability of observing landslide scars in the bathymetry data. If the latter is the case, an inverse power-law distribution with an exponent of 1.3 ?? 0.3, modified by a size-dependent conditional probability of identifying more failure scars with increasing landslide size, fits the observed size distribution. This exponent value is similar to the predicted exponent of 1.2 ?? 0.3 for subaerial landslides in unconsolidated material. Both the log-normal and modified inverse power-law distributions of the observed failure scar volumes suggest that large landslides, which have the greatest potential to generate damaging tsunamis, occur infrequently along the margin. ?? 2008 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.margeo.2008.08.007","issn":"00253227","usgsCitation":"Chaytor, J., ten Brink, U., Solow, A., and Andrews, B., 2009, Size distribution of submarine landslides along the U.S. Atlantic margin: Marine Geology, v. 264, no. 1-2, p. 16-27, https://doi.org/10.1016/j.margeo.2008.08.007.","startPage":"16","endPage":"27","numberOfPages":"12","costCenters":[],"links":[{"id":245424,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217474,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2008.08.007"}],"volume":"264","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b911ae4b08c986b319769","contributors":{"authors":[{"text":"Chaytor, J.D.","contributorId":80936,"corporation":false,"usgs":true,"family":"Chaytor","given":"J.D.","affiliations":[],"preferred":false,"id":457074,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"ten Brink, Uri S. 0000-0001-6858-3001 utenbrink@usgs.gov","orcid":"https://orcid.org/0000-0001-6858-3001","contributorId":127560,"corporation":false,"usgs":true,"family":"ten Brink","given":"Uri S.","email":"utenbrink@usgs.gov","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":false,"id":457075,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Solow, A.R.","contributorId":9404,"corporation":false,"usgs":true,"family":"Solow","given":"A.R.","email":"","affiliations":[],"preferred":false,"id":457073,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Andrews, B.D.","contributorId":87737,"corporation":false,"usgs":true,"family":"Andrews","given":"B.D.","email":"","affiliations":[],"preferred":false,"id":457076,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70036944,"text":"70036944 - 2009 - Do summer temperatures trigger spring maturation in pacific lamprey, Entosphenus tridentatus?","interactions":[],"lastModifiedDate":"2012-03-12T17:22:00","indexId":"70036944","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1471,"text":"Ecology of Freshwater Fish","active":true,"publicationSubtype":{"id":10}},"title":"Do summer temperatures trigger spring maturation in pacific lamprey, Entosphenus tridentatus?","docAbstract":"Pacific lamprey, Entosphenus tridentatus, return to streams and use somatic energy to fuel maturation.

Lamprey from the warm water group showed significantly greater proportional decreases in body weight following the summer temperature treatments than fish from the cool water group. A greater proportion of warm water fish sexually matured (100%) and died (97%) the following spring than cool water fish (53% sexually mature, 61% died).

Spatially, they occur most commonly in fjords, active river deltas, submarine canyon-fan systems, the open continental slope and on the flanks of oceanic volcanic islands. Temporally, they are influenced by the size, location, and sedimentology of migrating depocenters, changes in seafloor pressures and temperatures, variations in seismicity and volcanic activity, and changes in groundwater flow conditions. The dominant factor influencing the timing of submarine landslide occurrence is glaciation. A review of known ages of submarine landslides along the margins of the Atlantic Ocean, augmented by a few ages from other submarine locations shows a relatively even distribution of large landslides with time from the last glacial maximum until about five thousand years after the end of glaciation. During the past 5000??yr, the frequency of occurrence is less by a factor of 1.7 to 3.5 than during or shortly after the last glacial/deglaciation period. Such an association likely exists because of the formation of thick deposits of sediment on the upper continental slope during glacial periods and increased seismicity caused by isostatic readjustment during and following deglaciation. Hydrate dissociation may play a role, as suggested previously in the literature, but the connection is unclear.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.margeo.2008.09.009","issn":"00253227","usgsCitation":"Lee, H., 2009, Timing of occurrence of large submarine landslides on the Atlantic Ocean margin: Marine Geology, v. 264, no. 1-2, p. 53-64, https://doi.org/10.1016/j.margeo.2008.09.009.","startPage":"53","endPage":"64","numberOfPages":"12","costCenters":[],"links":[{"id":217637,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2008.09.009"},{"id":245594,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"264","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb3f2e4b08c986b3260ad","contributors":{"authors":[{"text":"Lee, H.J.","contributorId":96693,"corporation":false,"usgs":true,"family":"Lee","given":"H.J.","email":"","affiliations":[],"preferred":false,"id":458589,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70036631,"text":"70036631 - 2009 - Airborne gamma-ray and magnetic anomaly signatures of serpentinite in relation to soil geochemistry, northern California","interactions":[],"lastModifiedDate":"2012-03-12T17:22:08","indexId":"70036631","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":835,"text":"Applied Geochemistry","active":true,"publicationSubtype":{"id":10}},"title":"Airborne gamma-ray and magnetic anomaly signatures of serpentinite in relation to soil geochemistry, northern California","docAbstract":"Serpentinized ultramafic rocks and associated soils in northern California are characterized by high concentrations of Cr and Ni, low levels of radioelements (K, Th, and U) and high amounts of ferrimagnetic minerals (primarily magnetite). Geophysical attributes over ultramafic rocks, which include airborne gamma-ray and magnetic anomaly data, are quantified and provide indirect measurements on the relative abundance of radioelements and magnetic minerals, respectively. Attributes are defined through a statistical modeling approach and the results are portrayed as probabilities in chart and map form. Two predictive models are presented, including one derived from the aeromagnetic anomaly data and one from a combination of the airborne K, Th and U gamma-ray data. Both models distinguish preferential values within the aerogeophysical data that coincide with mapped and potentially unmapped ultramafic rocks. The magnetic predictive model shows positive probabilities associated with magnetic anomaly highs and, to a lesser degree, anomaly lows, which accurately locate many known ultramafic outcrops, but more interestingly, locate potentially unmapped ultramafic rocks, possible extensions of ultramafic bodies that dip into the shallow subsurface, as well as prospective buried ultramafic rocks. The airborne radiometric model shows positive probabilities in association with anomalously low gamma radiation measurements over ultramafic rock, which is similar to that produced by gabbro, metavolcanic rock, and water bodies. All of these features share the characteristic of being depleted in K, Th and U. Gabbro is the only rock type in the study area that shares similar magnetic properties with the ultramafic rock. The aerogeophysical model results are compared to the distribution of ultramafic outcrops and to Cr, Ni, K, Th and U concentrations and magnetic susceptibility measurements from soil samples. Analysis of the soil data indicates high positive correlation between magnetic susceptibilities and concentration of Cr and Ni. Although the study focused on characterizing the geophysical properties of ultramafic rocks and associated soils, it has also yielded information on other rock types in addition to ultramafic rocks, which can also locally host naturally-occurring asbestos; specifically, gabbro and metavolcanic rocks.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2009.04.007","issn":"08832927","usgsCitation":"McCafferty, A.E., and Van Gosen, B.S., 2009, Airborne gamma-ray and magnetic anomaly signatures of serpentinite in relation to soil geochemistry, northern California: Applied Geochemistry, v. 24, no. 8, p. 1524-1537, https://doi.org/10.1016/j.apgeochem.2009.04.007.","startPage":"1524","endPage":"1537","numberOfPages":"14","costCenters":[],"links":[{"id":245395,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217446,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2009.04.007"}],"volume":"24","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e920e4b0c8380cd480f6","contributors":{"authors":[{"text":"McCafferty, A.

Acid-neutralizing capacity (ANC) of 151 lakes sampled during synoptic surveys and basin-characteristic information derived from geographic information system (GIS) data sets were used to calibrate the statistical models. The explanatory basin variables that were considered included topographic parameters, bedrock type, and vegetation type. A logistic regression model was developed, and modeling results were cross-validated through lake sampling during fall 2004 at 58 lakes. The model was applied to lake basins greater than 1 ha in area in Glacier National Park (n = 244 lakes), Grand Teton National Park (n = 106 lakes), Great Sand Dunes National Park and Preserve (n = 11 lakes), Rocky Mountain National Park (n = 114 lakes), and Yellowstone National Park (n = 294 lakes). Lakes that had a high probability of having an ANC concentration <100 μeq/L, and therefore sensitive to acidic deposition, are located in basins with elevations >3000 m, with <30% of the catchment having northeast aspect and with >80% of the catchment bedrock having low buffering capacity. The modeling results indicate that the most sensitive lakes are located in Rocky Mountain National Park and Grand Teton National Park. This technique for evaluating the lake sensitivity to acidic deposition is useful for designing long-term monitoring plans and is potentially transferable to other remote mountain areas of the United States and the world.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/07-1091.1","issn":"10510761","usgsCitation":"Nanus, L., Williams, M., Campbell, K., Tonnessen, K., Blett, T., and Clow, D.W., 2009, Assessment of lake sensitivity to acidic deposition in national parks of the Rocky Mountains: Ecological Applications, v. 19, no. 4, p. 961-973, https://doi.org/10.1890/07-1091.1.","productDescription":"13 p.","startPage":"961","endPage":"973","costCenters":[{"id":639,"text":"Water Resources of the United States","active":false,"usgs":true}],"links":[{"id":476299,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1890/07-1091.1","text":"Publisher Index Page"},{"id":217845,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/07-1091.1"},{"id":245817,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado;Idaho;Montana;Wyoming","otherGeospatial":"Glacier National Park;Grand Teton National Park;Great Sand Dunes National Park And Preserve;Rocky Mountain National Park;Yellowstone National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.48,37.66 ], [ -114.48,49.0 ], [ -105.43,49.0 ], [ -105.43,37.66 ], [ -114.48,37.66 ] ] ] } } ] }","volume":"19","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ee3ce4b0c8380cd49c3f","contributors":{"authors":[{"text":"Nanus, L.","contributorId":83239,"corporation":false,"usgs":true,"family":"Nanus","given":"L.","affiliations":[],"preferred":false,"id":457068,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Williams, M.W.","contributorId":15565,"corporation":false,"usgs":true,"family":"Williams","given":"M.W.","email":"","affiliations":[],"preferred":false,"id":457063,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Campbell, K.","contributorId":63351,"corporation":false,"usgs":false,"family":"Campbell","given":"K.","affiliations":[{"id":47665,"text":"St. Anthony Falls Laboratory, University of Minnesota, Minneapolis, MN, USA","active":true,"usgs":false}],"preferred":false,"id":457066,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tonnessen, K.A.","contributorId":30196,"corporation":false,"usgs":true,"family":"Tonnessen","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":457065,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Blett, T.","contributorId":67828,"corporation":false,"usgs":true,"family":"Blett","given":"T.","email":"","affiliations":[],"preferred":false,"id":457067,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Clow, D.

Here we review evidence from different disciplines demonstrating that wildfire appeared concomitant with the origin of terrestrial plants and played an important role throughout the history of life. The importance of fire has waxed and waned in association with changes in climate and paleoatmospheric conditions. Well before the emergence of humans on Earth, fire played a key role in the origins of plant adaptations as well as in the distribution of ecosystems. Humans initiated a new stage in ecosystem fire, using it to make the Earth more suited to their lifestyle. However, as human populations have expanded their use of fire, their actions have come to dominate some ecosystems and change natural processes in ways that threaten the sustainability of some landscapes. ?? 2009 by American Institute of Biological Sciences.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"BioScience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1525/bio.2009.59.7.10","issn":"00063568","usgsCitation":"Pausas, J., and Keeley, J., 2009, A burning story: The role of fire in the history of life: BioScience, v. 59, no. 7, p. 593-601, https://doi.org/10.1525/bio.2009.59.7.10.","startPage":"593","endPage":"601","numberOfPages":"9","costCenters":[],"links":[{"id":476423,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/10261/57324","text":"External Repository"},{"id":217844,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1525/bio.2009.59.7.10"},{"id":245816,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"59","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e333e4b0c8380cd45e9b","contributors":{"authors":[{"text":"Pausas, J.G.","contributorId":33279,"corporation":false,"usgs":true,"family":"Pausas","given":"J.G.","affiliations":[],"preferred":false,"id":457061,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keeley, Jon E. 0000-0002-4564-6521","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":69082,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon E.","affiliations":[],"preferred":false,"id":457062,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70036749,"text":"70036749 - 2009 - Hydrolysis of polycarbonate in sub-critical water in fused silica capillary reactor with in situ Raman spectroscopy","interactions":[],"lastModifiedDate":"2017-11-29T11:36:41","indexId":"70036749","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1860,"text":"Green Chemistry","active":true,"publicationSubtype":{"id":10}},"title":"Hydrolysis of polycarbonate in sub-critical water in fused silica capillary reactor with in situ Raman spectroscopy","docAbstract":"The advantages of using fused silica capillary reactor (FSCR) instead of conventional autoclave for studying chemical reactions at elevated pressure and temperature conditions were demonstrated in this study, including the allowance for visual observation under a microscope and in situ Raman spectroscopic characterization of polycarbonate and coexisting phases during hydrolysis in subcritical water.

The use of isotopically enriched Hg species in environmental studies now allows experimentally applied new Hg to be distinguished from ambient Hg naturally present in the system. Four different enriched stable Hg(II) isotope “spikes” were applied sequentially over four years to the ground vegetation of a microcatchment at the Experimental Lakes Area (ELA) in the remote boreal forest of Canada to examine retention of Hg(II) following deposition. Areal masses of the spikes and ambient THg (all forms of Hg in a sample) were monitored for eight years, and the pattern of spike retention was used to estimate retention of newly deposited ambient Hg within the ground vegetation pool. Fifty to eighty percent of applied spike Hg was initially retained by ground vegetation. The areal mass of spike Hg declined exponentially over time and was best described by a first-order process with constants (k) ranging between 9.7 × 10−4 day−1 and 11.6 × 10−4day−1. Average half-life (t1/2) of spike Hg within the ground vegetation pool (±S.D.) was 704 ± 52 days. This retention of new atmospheric Hg(II) by vegetation delays movement of new Hg(II) into soil, runoff, and finally into adjacent lakes. Ground-applied Hg(II) spikes were not detected in tree foliage and litterfall, indicating that stomatal and/or root uptake of previously deposited Hg (i.e., “recycled” from ground vegetation or soil Hg pools) were likely not large sources of foliar Hg under these experimental conditions.

Fluvial sediment transport and deposition paradoxically represent ecological disturbance and restoration. A one-dimensional, movable boundary sediment-transport model was applied at a daily time step to simulate changes in river-bed elevations and particle-size distributions and concentrations of suspended sediment. The simulations included a three-year dam removal period and a four-year recovery period. Simulated concentrations of suspended sediment recover rapidly during the recovery period. Simulated bed elevation and particle-size distributions are stable for much of the river during the recovery period, but high flows periodically disturb the river bed, causing changes in river-bed elevation and particle-size distribution, especially during autumn, when summer/autumn chinook salmon are incubating in redds. Although the river bed will become increasingly stable after dam removal, episodic high flows will interrupt recovery trends. Productivity and diversity of the ecosystem may be lower because of excess sediment immediately after dam removal but should increase during recovery above current levels as the river. Monitoring of the recovery of the Elwha River ecosystem can target ecologically significant physical parameters indicating the transition from a sediment transport-limited state to a supply-limited state.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecoleng.2009.03.018","issn":"09258574","usgsCitation":"Konrad, C., 2009, Simulating the recovery of suspended sediment transport and river-bed stability in response to dam removal on the Elwha River, Washington: Ecological Engineering, v. 35, no. 7, p. 1104-1115, https://doi.org/10.1016/j.ecoleng.2009.03.018.","startPage":"1104","endPage":"1115","numberOfPages":"12","costCenters":[],"links":[{"id":217878,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecoleng.2009.03.018"},{"id":245851,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8fdce4b08c986b3191a9","contributors":{"authors":[{"text":"Konrad, C.P.","contributorId":39027,"corporation":false,"usgs":true,"family":"Konrad","given":"C.P.","email":"","affiliations":[],"preferred":false,"id":457394,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70194409,"text":"70194409 - 2009 - Ectoparasites of the occult bat, Myotis occultus (Chiroptera: Vespertilionidae)","interactions":[],"lastModifiedDate":"2017-11-27T16:54:24","indexId":"70194409","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3746,"text":"Western North American Naturalist","onlineIssn":"1944-8341","printIssn":"1527-0904","active":true,"publicationSubtype":{"id":10}},"displayTitle":"Ectoparasites of the occult bat, Myotis occultus (Chiroptera: Vespertilionidae)","title":"Ectoparasites of the occult bat, Myotis occultus (Chiroptera: Vespertilionidae)","docAbstract":"Only a single previous study has examined ectoparasites of the occult bat (Myotis occultus), from which only 2 species of fleas were identified. For our study, we examined 202 individuals, 52 fresh hosts and 150 museum specimens, from New Mexico and southern Colorado for ectoparasites. We recorded 2158 ectoparasites, 634 from fresh hosts and 1524 from museum specimens. Ectoparasites belonged to 10 families and 13 genera of insect or acari and represent new host and locality records. In general, ectoparasites collected from fresh hosts and museum specimens were represented by 4 major species of mite: Macronyssus crosbyi, Alabidocarpus calcaratus, Acanthophthirius lucifugus, and Alabidocarpus nr. eptesicus. From our study, we found fresh hosts to have significantly greater prevalence values for Myodopsylla gentilis (flea), Chiroptonyssus robustipes (mite), and Leptotrombidium myotis (chigger), whereas museum specimens had significantly greater prevalence values for A. calcaratus(mite) and A. nr. eptesicus (mite). There were no significant differences between prevalence values for 4 mites including M. crosbyi, A. lucifugus, Pteracarus nr. minutus, and Cryptonyssussp. Our study represents the only extensive study of ectoparasites on M. occultus and provides evidence for the importance of examining fresh hosts and museum specimens in future ectoparasite studies.

The scope of this article is limited to observations because there are significant differences in the analysis of finite and infinitesimal rotations, though such discussions should remain compatible with those presented here where possible.

MLEE and AFLP revealed considerable genetic variability among B. bassiana isolates. Several isolates from South and Southeast Brazil had high similarity coefficients, providing evidence of at least one population with clonal structure. There were clear genomic differences between most Brazilian and USA B. bassiana isolates. A Mantel test using data generated by AFLP provided evidence that greater geographical distances were associated with higher genetic distances. AFLP and rDNA sequencing demonstrated notable genotypic variation between B. bassiana and other Beauveria spp. Conclusion: Geographical distance between populations apparently is an important factor influencing genotypic variability among B. bassiana populations in Brazil. Significance and Impact of the Study: This study characterized many B. bassiana isolates. The results indicate that certain Brazilian isolates are considerably different from others and possibly should be regarded as separate species from B. bassiana sensu latu. The information on genetic variation among the Brazilian isolates, therefore, will be important to comprehending the population structure of B. bassiana in Brazil. ?? 2009 The Society for Applied Microbiology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Microbiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2672.2009.04258.x","issn":"13645072","usgsCitation":"Fernandes, E., Moraes, A., Pacheco, R., Rangel, D., Miller, M., Bittencourt, V., and Roberts, D., 2009, Genetic diversity among brazilian isolates of beauveria bassiana: comparisons with non-brazilian isolates and other beauveria species: Journal of Applied Microbiology, v. 107, no. 3, p. 760-774, https://doi.org/10.1111/j.1365-2672.2009.04258.x.","startPage":"760","endPage":"774","numberOfPages":"15","costCenters":[],"links":[{"id":476137,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://www.arca.fiocruz.br/handle/icict/28133","text":"Publisher Index Page"},{"id":217852,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2672.2009.04258.x"},{"id":245824,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"107","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1571e4b0c8380cd54dfa","contributors":{"authors":[{"text":"Fernandes, E.K.K.","contributorId":87384,"corporation":false,"usgs":true,"family":"Fernandes","given":"E.K.K.","email":"","affiliations":[],"preferred":false,"id":457672,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moraes, A.M.L.","contributorId":17077,"corporation":false,"usgs":true,"family":"Moraes","given":"A.M.L.","email":"","affiliations":[],"preferred":false,"id":457668,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pacheco, R.S.","contributorId":39221,"corporation":false,"usgs":true,"family":"Pacheco","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":457670,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rangel, D.E.N.","contributorId":32362,"corporation":false,"usgs":true,"family":"Rangel","given":"D.E.N.","email":"","affiliations":[],"preferred":false,"id":457669,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Miller, M.P.","contributorId":47142,"corporation":false,"usgs":true,"family":"Miller","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":457671,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bittencourt, V.R.E.P.","contributorId":91342,"corporation":false,"usgs":true,"family":"Bittencourt","given":"V.R.E.P.","email":"","affiliations":[],"preferred":false,"id":457673,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Roberts, D.W.","contributorId":11828,"corporation":false,"usgs":true,"family":"Roberts","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":457667,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ,{"id":70036692,"text":"70036692 - 2009 - Remote monitoring of tamarisk defoliation and evapotranspiration following saltcedar leaf beetle attack","interactions":[],"lastModifiedDate":"2012-03-12T17:22:01","indexId":"70036692","displayToPublicDate":"2009-01-01T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3254,"text":"Remote Sensing of Environment","printIssn":"0034-4257","active":true,"publicationSubtype":{"id":10}},"title":"Remote monitoring of tamarisk defoliation and evapotranspiration following saltcedar leaf beetle attack","docAbstract":"Tamarisk (Tamarix spp.) has invaded riparian ecosystems throughout the Western United States, including significant portions of riparian ecosystems within U.S. National Parks and Monuments. Recently, the saltcedar leaf beetle (Diorhabda elongata) was released as a tamarisk biocontrol agent. Although initial releases have been monitored, no comprehensive program is currently in place to monitor the rapid spread of Diorhabda that has resulted from numerous subsequent releases by county and state agencies. Long term monitoring of tamarisk defoliation and its impacts on habitat and water resources is needed. This study examines the potential for using higher spatial resolution Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data and lower spatial resolution Moderate Resolution Imaging Spectroradiometer (MODIS) data for monitoring defoliation caused by Diorhabda and subsequent changes in evapotranspiration (ET). Widespread tamarisk defoliation was observed in an eastern Utah study area during summer 2007. ASTER normalized difference vegetation index (NDVI) showed only minor changes between 2005 and 2006, but a significant drop in NDVI was found within riparian areas between 2006 and 2007. The decrease in NDVI caused by defoliation was apparent despite partial refoliation within the study area. MODIS time series data revealed that absolute decline in EVI varied by site, but that the timing of EVI decline during summer 2007 was early with respect to phenological patterns from 2001 through 2006. Defoliation caused decreases in ET values estimated from both ASTER and MODIS data. MODIS estimated ET declined earlier than in previous years, although annual ET was not significantly different than ET in previous years due to high year-to-year variability. Challenges to detection and monitoring of tamarisk defoliation include spectral mixing of tamarisk and other cover types at subpixel spatial resolution, spatial coregistration of time series images, the timing of image acquisition, and changes unrelated to defoliation in non-tamarisk land cover over time. Continued development of the techniques presented in this paper may allow monitoring the spread of Diorhabda and assessment of potential water salvage resulting from biocontrol of tamarisk. ?? 2009 Elsevier Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Remote Sensing of Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.rse.2008.05.022","issn":"00344257","usgsCitation":"Dennison, P., Nagler, P., Hultine, K.R., Glenn, E.P., and Ehleringer, J., 2009, Remote monitoring of tamarisk defoliation and evapotranspiration following saltcedar leaf beetle attack: Remote Sensing of Environment, v. 113, no. 7, p. 1462-1472, https://doi.org/10.1016/j.rse.2008.05.022.","startPage":"1462","endPage":"1472","numberOfPages":"11","costCenters":[],"links":[{"id":217877,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.rse.2008.05.022"},{"id":245850,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"113","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa6efe4b0c8380cd8511f","contributors":{"authors":[{"text":"Dennison, P.E.","contributorId":73430,"corporation":false,"usgs":true,"family":"Dennison","given":"P.E.","email":"","affiliations":[],"preferred":false,"id":457392,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nagler, P.L. 0000-0003-0674-103X","orcid":"https://orcid.org/0000-0003-0674-103X","contributorId":29937,"corporation":false,"usgs":true,"family":"Nagler","given":"P.L.","affiliations":[],"preferred":false,"id":457390,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hultine, K.
