Permafrost thaw affects soil carbon turnover through changes in soil hydrology, however, the biotic mechanisms regulating plant community response remain elusive. Here, we measured the response of fungal community composition and soil nutrient content in an intact permafrost plateau forest soil and an adjacent thermokarst bog using barcoded amplicon targeting ITS2 and 28S rRNA genes. Next, we used the soils from the permafrost plateau and the thermokarst bog as soil inoculum in a greenhouse experiment to measure whether shifts in fungal community and soil water level regulate plant productivity. Overall, we found that fungal community composition differed significantly between the thawed and intact permafrost sites, but soil nutrient content did not. Relative abundance of mycorrhizal fungal taxa decreased while relative abundance of putative fungal pathogens increased with permafrost thaw. In the greenhouse, we found that ecto- and arbuscular associated host plants had higher productivity in permafrost-intact soils relative to thawed soils. However, productivity of non-mycorrhizal tussock grass was more affected by soil water levels than soil communities. Our results suggest that fungal communities are crucial in mediating plant response to permafrost thaws inducing hydrology changes.","language":"English","publisher":"Wiley","doi":"10.1111/1365-2745.13139","usgsCitation":"Schütte, U., Henning, J.A., Ye, Y., Bowling, A., Ford, J.D., Genet, H., Waldrop, M., Turetsky, M.R., White, J.R., and Bever, J.D., 2019, Effect of permafrost thaw on plant and soil fungal community in the boreal forest: Does fungal community change mediate plant productivity response?: Journal of Ecology, v. 107, no. 4, p. 1737-1752, https://doi.org/10.1111/1365-2745.13139.","productDescription":"16 p.","startPage":"1737","endPage":"1752","ipdsId":"IP-103772","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":467984,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/1365-2745.13139","text":"Publisher Index Page"},{"id":365296,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"107","issue":"4","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2019-03-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Schütte, Ursel M.E","contributorId":216770,"corporation":false,"usgs":false,"family":"Schütte","given":"Ursel M.E","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":765468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Henning, Jeremiah A.","contributorId":216771,"corporation":false,"usgs":false,"family":"Henning","given":"Jeremiah","email":"","middleInitial":"A.","affiliations":[{"id":6626,"text":"University of Minnesota","active":true,"usgs":false}],"preferred":false,"id":765469,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ye, Yuzhen","contributorId":216772,"corporation":false,"usgs":false,"family":"Ye","given":"Yuzhen","email":"","affiliations":[{"id":39512,"text":"Indiana Univerisity","active":true,"usgs":false}],"preferred":false,"id":765470,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bowling, A.","contributorId":119396,"corporation":false,"usgs":true,"family":"Bowling","given":"A.","email":"","affiliations":[],"preferred":false,"id":765473,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ford, James D.","contributorId":200964,"corporation":false,"usgs":false,"family":"Ford","given":"James","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":765471,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Genet, Helene","contributorId":198686,"corporation":false,"usgs":false,"family":"Genet","given":"Helene","email":"","affiliations":[],"preferred":false,"id":765472,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Waldrop, Mark 0000-0003-1829-7140","orcid":"https://orcid.org/0000-0003-1829-7140","contributorId":216769,"corporation":false,"usgs":true,"family":"Waldrop","given":"Mark","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":765467,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Turetsky, Merritt R.","contributorId":169398,"corporation":false,"usgs":false,"family":"Turetsky","given":"Merritt","email":"","middleInitial":"R.","affiliations":[{"id":12660,"text":"University of Guelph","active":true,"usgs":false}],"preferred":false,"id":765474,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"White, Jeffrey R.","contributorId":169414,"corporation":false,"usgs":false,"family":"White","given":"Jeffrey","email":"","middleInitial":"R.","affiliations":[{"id":12645,"text":"Indiana University - Northwest","active":true,"usgs":false}],"preferred":false,"id":765475,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Bever, James D","contributorId":216774,"corporation":false,"usgs":false,"family":"Bever","given":"James","email":"","middleInitial":"D","affiliations":[{"id":39513,"text":"Kansas University","active":true,"usgs":false}],"preferred":false,"id":765476,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Fish mercury concentrations are variable within and among systems due to a suite of biotic and abiotic influences that vary among regions and are difficult to predict. Understanding factors associated with variability in fish mercury concentrations would help guide consumption advisories. Mercury concentrations in channel catfish (<i>Ictalurus punctatus</i>,<span>&nbsp;</span><i>n</i> = 205), flathead catfish (<i>Pylodictis olivaris</i>,<span>&nbsp;</span><i>n</i> = 123), northern pike (<i>Esox lucius</i>,<span>&nbsp;</span><i>n</i> = 60), smallmouth bass (<i>Micropterus dolomieu</i>,<span>&nbsp;</span><i>n</i> = 176), and walleye (<i>Sander vitreus</i>,<span>&nbsp;</span><i>n</i> = 176) were assessed in ten Iowa rivers and relationships with land use, water chemistry, and fish characteristics were explored. Mercury concentrations were generally low (mean among all species = 0.17 mg/kg,<span>&nbsp;</span><i>n</i> = 740) but higher in flathead catfish, northern pike, smallmouth bass, and walleye than channel catfish and were positively related to fish length, age, trophic position, and δ<sup>13</sup>C signatures. Phosphorus, sulfate, and percent open water and grassland were negatively related to fish mercury concentrations, whereas water hardness, nitrogen-ammonia, Human Threat Index, and percent wetland and forest were positively related to fish mercury concentrations. Fish collected from the Paleozoic Plateau ecoregion in northeast Iowa had higher mercury concentrations than other ecoregions in Iowa. Combined, these factors explained 70% of the variation in fish mercury concentrations. This study provides a comprehensive analysis of abiotic and biotic factors influencing fish mercury concentrations in lotic ecosystems at the individual and system scale that will help guide fish consumption advisories.</p></div></div>","language":"English","publisher":"Springer","doi":"10.1007/s10646-019-02017-1","usgsCitation":"Mills, N., Weber, M., Pierce, C., and Cashatt, D., 2019, Factors

SWOT discharge algorithms have been developed and benchmarked using synthetic data but remain untested on real‐world swath altimetry observations. We present the first discharge estimates from AirSWOT, a SWOT‐like airborne Ka‐band radar, using 6&nbsp;days of measurements over a 40‐km segment of the Willamette River in Oregon, USA. The three evaluated discharge algorithms estimated discharge with normalized root‐mean‐square errors of 10–31% when compared with in situ gage data but were sensitive to an initial estimate of mean annual discharge. Our results show that these discharge algorithms provide reliable discharge estimates on remotely sensed data at SWOT‐like spatial scales while highlighting the need for further algorithm sensitivity tests.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2018GL080771","usgsCitation":"Tuozzolo, S., Lind, G.D., Overstreet, B., Mangano, J.F., Fonstad, M.A.,

Prediction of these changes is challenged by incomplete knowledge of timing, flowpath depth, and amount of groundwater discharge to streams in response to thaw. One important phenomenon that may affect flow and transport through boreal hillslopes is development of lateral perennial thaw zones (PTZs), the existence of which is here supported by geophysical observations and cryohydrogeologic modeling. Model results link thaw to enhanced and seasonally-extended baseflow, which have implications for mobilization of soluble constituents. Results demonstrate the sensitivity of PTZ development to organic layer thickness and near-surface factors that mediate heat exchange at the atmosphere/ground-surface interface. Study findings suggest that PTZs serve as a detectable precursor to accelerated permafrost degradation. This study provides important contextual insight on a fundamental thermo-hydrologic process that can enhance terrestrial-to-aquatic transfer of permafrost carbon, nitrogen, and mercury previously sequestered in thawing watersheds.</span></p>","language":"English","publisher":"IOP Publishing","doi":"10.1088/1748-9326/aaf0cc","usgsCitation":"Walvoord, M.A., Voss, C., Ebel, B., and Minsley, B.J., 2019, Development of perennial thaw zones in boreal hillslopes enhances potential mobilization of permafrost carbon: Environmental Research Letters, v. 14, no. 1, p. 1-11, https://doi.org/10.1088/1748-9326/aaf0cc.","productDescription":"Article 015003; 11 p.","startPage":"1","endPage":"11","ipdsId":"IP-098066","costCenters":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"links":[{"id":467989,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1088/1748-9326/aaf0cc","text":"Publisher Index Page"},{"id":437601,"rank":0,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P9HWCOBP","text":"USGS data release","linkHelpText":"Model Archive for coupled energy and fluid flow simulations generalized to boreal hillslopes"},{"id":360760,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"14","issue":"1","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2019-01-17","publicationStatus":"PW","scienceBaseUri":"5c5022c3e4b0708288f7e800","contributors":{"authors":[{"text":"Walvoord, Michelle A. 0000-0003-4269-8366","orcid":"https://orcid.org/0000-0003-4269-8366","contributorId":211843,"corporation":false,"usgs":true,"family":"Walvoord","given":"Michelle","email":"","middleInitial":"A.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755031,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Voss, Clifford I. 0000-0001-5923-2752","orcid":"https://orcid.org/0000-0001-5923-2752","contributorId":211844,"corporation":false,"usgs":true,"family":"Voss","given":"Clifford I.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755032,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ebel, Brian A. 0000-0002-5413-3963","orcid":"https://orcid.org/0000-0002-5413-3963","contributorId":211845,"corporation":false,"usgs":true,"family":"Ebel","given":"Brian A.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":755033,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Minsley, Burke J. 0000-0003-1689-1306 bminsley@usgs.gov","orcid":"https://orcid.org/0000-0003-1689-1306","contributorId":697,"corporation":false,"usgs":true,"family":"Minsley","given":"Burke","email":"bminsley@usgs.gov","middleInitial":"J.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":755034,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

To investigate this knowledge gap, we used a six‐year data set of daily surface water nitrate concentration and discharge averaged from near‐continuous monitoring at U.S. Geological Survey gaging stations on the Connecticut, Potomac, and Mississippi Rivers, three large rivers that contribute substantial nutrient pollution to important estuaries. Interannually, a comparison of nitrate concentration‐discharge (c‐Q) relationships between a traditional discrete grab sample data set and the near‐continuous data set revealed differing c‐Q slopes, which suggests that sample frequency can impact how we ultimately characterize hydrologic systems. Intraannually, we conducted correlation analyses over 30‐day windows to isolate the strength and direction of monthly c‐Q relationships. Monthly c‐Q slopes in the Potomac were positive (enrichment/mobilization response) in summer and fall and negative (dilution response) and weakly chemostatic (nonsignificant near‐zero c‐Q slope) in winter and spring, respectively. The Connecticut displayed a dilution response year‐round, except summer when it was weakly chemostatic. Mississippi c‐Q slopes were weakly chemostatic in all seasons and showed inconsistent responses to discharge fluctuations. The c‐Q dynamics in the Potomac and Connecticut were correlated (</span><i>R</i><span>&nbsp;&gt;&nbsp;0.3) to river temperature, flow percentile, and calendar day. Minimal correlation in the Mississippi suggests that the large basin area coupled with spatiotemporally variable anthropogenic forcings from substantial land use development created stochastic short‐term c‐Q relationships.

Climate change models generally predict decreased streamflows and increased water temperatures that may further affect these species. Understanding the effects of flow and water temperature on their life histories should lead to better assessments of climate change impacts on extant populations and more informed management for species conservation. Basinwide larval fish sampling and hatch dates derived from otolith daily increment counts showed that water temperature was the dominant environmental factor cueing reproduction in the upper White River basin, Colorado. Reproduction for all three species began in spring, occurring first at warmer, lower-elevation, downstream locations and progressing upriver to higher elevations as water temperatures increased. Warmer water temperatures in tributaries initiated earlier reproductive activity compared to adjacent cooler main-stem habitat. Presence of larvae in samples and estimated hatch dates demonstrated a distinct, predictable upstream progression of reproduction associated with warming water and clear upstream limits to reproduction for all three species. Larval presence and hatching dates revealed earlier reproductive activity in 2012 than in 2013, driven by lower flow and earlier stream warming. A regression model predicted stream temperature during fish spawning seasons under different climate change scenarios and showed expanded upstream limits of thermally suitable reproductive habitat and earlier reproduction for our study species. The long-term implications of climate change are unknown, but managers should strive to perpetuate the valuable and relatively pristine native fish community in the upper White River drainage as a vestige of those that formerly existed throughout the Colorado River basin.</span></p>","language":"English","publisher":"American Fisheries Society","doi":"10.1002/tafs.10151","usgsCitation":"Fraser, G., Bestgen, K., Winkelman, D.L., and Thompson, K.G., 2019, Temperature–not flow–predicts native fish reproduction with Implications for climate change: Transactions of the American Fisheries Society, v. 148, no. 3, p. 509-527, https://doi.org/10.1002/tafs.10151.","productDescription":"19 p.","startPage":"509","endPage":"527","ipdsId":"IP-101495","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":467991,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/tafs.10151","text":"Publisher Index Page"},{"id":388233,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"White River headwaters","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -108.951416015625,\n              39.78532331459258\n            ],\n            [\n              -107.193603515625,\n              39.78532331459258\n            ],\n            [\n              -107.193603515625,\n              40.233411907115055\n            ],\n            [\n              -108.951416015625,\n              40.233411907115055\n            ],\n            [\n              -108.951416015625,\n              39.78532331459258\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"148","issue":"3","noUsgsAuthors":false,"publicationDate":"2019-03-22","publicationStatus":"PW","contributors":{"authors":[{"text":"Fraser, Gregory S.","contributorId":264508,"corporation":false,"usgs":false,"family":"Fraser","given":"Gregory S.","affiliations":[{"id":37461,"text":"fws","active":true,"usgs":false}],"preferred":false,"id":821623,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bestgen, Kevin R.","contributorId":264509,"corporation":false,"usgs":false,"family":"Bestgen","given":"Kevin R.","affiliations":[{"id":13606,"text":"CSU","active":true,"usgs":false}],"preferred":false,"id":821624,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Winkelman, Dana L. 0000-0002-5247-0114 danaw@usgs.gov","orcid":"https://orcid.org/0000-0002-5247-0114","contributorId":4141,"corporation":false,"usgs":true,"family":"Winkelman","given":"Dana","email":"danaw@usgs.gov","middleInitial":"L.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":821622,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Thompson, Kevin G.","contributorId":264512,"corporation":false,"usgs":false,"family":"Thompson","given":"Kevin","email":"","middleInitial":"G.","affiliations":[{"id":54484,"text":"co pw","active":true,"usgs":false}],"preferred":false,"id":821625,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Distinctive features include its geomorphically intact geyser vent mounds, the presence of growth-fault-stepped sinter terraces that developed westward along a NNW trending fault, and atypical Hg, Sb and As concentrations. High-temperature (&gt;75 °C), subaerial, proximal apron sinter occurs in two settings – (1) radiating botryoidal geyserite in vent mounds and (2) bedded geyserite (columnar, nodular, size-sorted geyser eggs) intercalated with mid- to low-temperature (&lt;60 °C), middle to distal apron terrace sinter. The active geyser vent mounds migrated from south to north across the apron terrace through time. A newly recognized, visually striking type of sinter – termed silica infiltrate herein – formed directly beneath the subaerial geyserite deposits. It is characterized by mainly parallel, thin, irregular beds of white silica with narrow borders of dark blue-gray silica, as well as swirly to globular white silica, all chaotically linked together by silica ‘necks’ and ‘bridges’. The silica infiltrate permeates the pre-existing sinter, and is interpreted to represent super-heated fluid injections into the immediately overlying geyser vent mounds and pools. The adjacent sinter sheets preserve fluid-flow directions of warm-water channels that traversed the discharge apron, including microbial streamer fabric and wavy laminated sinter with flattened bubbles. More distal sinter textures are recorded by rimmed terracettes with mammillated and palisade microbial fabrics and rare, warm pool-related stromatolites. However, plants are absent, probably due to the high metalloids, in particular As. Post-depositional events include an inferred hydrothermal eruption breccia and an interpreted drop in the water table accompanied by incursion of steam acid condensate, as evidenced by pervasive hydrothermal alteration of the Atastra Creek deposits. Hence, the well-exposed sedimentary facies distributions, well-preserved geomorphology, and stratigraphic and structural relationships together allow an unusually complete, paleoenvironmental reconstruction of the Atastra Creek paleohydrothermal deposit.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jvolgeores.2018.12.006","usgsCitation":"Campbell, K.A., Guido, D.M., John, D.A., Vikre, P., Rhys, D., and Hamilton, A., 2019, The Miocene Atastra Creek sinter (Bodie Hills volcanic field, California and Nevada): 4D evolution of a geomorphically intact siliceous hot spring deposit: Journal of Volcanology and Geothermal Research, v. 370, p. 65-81, https://doi.org/10.1016/j.jvolgeores.2018.12.006.","productDescription":"17 p.","startPage":"65","endPage":"81","ipdsId":"IP-102174","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":502590,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/11336/104267","text":"External Repository"},{"id":426119,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"370","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Campbell, Kathleen A. 0000-0002-4815-2519","orcid":"https://orcid.org/0000-0002-4815-2519","contributorId":334434,"corporation":false,"usgs":false,"family":"Campbell","given":"Kathleen","email":"","middleInitial":"A.","affiliations":[{"id":38833,"text":"University of Auckland","active":true,"usgs":false}],"preferred":false,"id":895630,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guido, Diego M. 0000-0003-4696-5644","orcid":"https://orcid.org/0000-0003-4696-5644","contributorId":334435,"corporation":false,"usgs":false,"family":"Guido","given":"Diego","email":"","middleInitial":"M.","affiliations":[{"id":80146,"text":"Universidad Nacional de La Plata, La Plata, Argentina","active":true,"usgs":false}],"preferred":false,"id":895631,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"John, David A. 0000-0001-7977-9106 djohn@usgs.gov","orcid":"https://orcid.org/0000-0001-7977-9106","contributorId":1748,"corporation":false,"usgs":true,"family":"John","given":"David","email":"djohn@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":895632,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vikre, Peter 0000-0001-7895-5972","orcid":"https://orcid.org/0000-0001-7895-5972","contributorId":203922,"corporation":false,"usgs":true,"family":"Vikre","given":"Peter","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":895633,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Rhys, David","contributorId":334437,"corporation":false,"usgs":false,"family":"Rhys","given":"David","email":"","affiliations":[{"id":12586,"text":"Consultant","active":true,"usgs":false}],"preferred":false,"id":895634,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hamilton, Ayrton","contributorId":334438,"corporation":false,"usgs":false,"family":"Hamilton","given":"Ayrton","email":"","affiliations":[{"id":38833,"text":"University of Auckland","active":true,"usgs":false}],"preferred":false,"id":895635,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

However, the assumption that Walleyes undertake diel vertical migrations and become available to the suspended gill nets at night has never been validated. To understand how vertical habitat use affects the availability of Walleyes to fishery‐independent surveys, we compared individual behaviors observed by means of acoustic depth telemetry tags (20 individuals; 2013–2016) with catches in paired suspended and bottom gill‐net sets (273 paired sets; 2013–2016) used by management agencies. In contrast to our expectations and observations in other lakes, the mean depths for Walleyes most often occurred in the lower one‐half to one‐third of the water column, and at lake depths <25 m the fish tended to be close to the bottom. The relationship between fish and lake depth was dependent on year and season. At lake depths >15 m, Walleyes were found at shallower depths during stratified periods (i.e., summer) than during unstratified periods (autumn). They were also found at shallower depths in 2015 and 2016 than in 2013 and 2014. In paired autumn gill‐net surveys, (1) the overall proportion of Walleye catch was nearly equal in suspended and bottom gill nets and (2) the proportion of the catch in suspended gill nets declined with fish length. The pattern of decline was dependent on how deep the suspended net was fished and the year in which the data were collected. These results provide evidence that the suspended gill‐net surveys currently being used to assess Walleye demographics in Lake Erie are biased toward the capture small Walleyes, while bottom nets are biased toward the capture of large ones. Future telemetry investigations will be needed to understand whether these biases reflect differences in the depth of habitat between small and large Walleyes.","language":"English","doi":"10.1002/tafs.10150","usgsCitation":"Ann Marie Gorman, Kraus, R.T., Gutowsky, L., Vandergoot, C., Yingming Zhao, Knight, C., Faust, M., Hayden, T., and Charles Krueger, 2019, Vertical habitat use of adult Walleye conflicts with expectations from fishery-independent surveys: Transactions of the American Fisheries Society, v. 148, no. 3, p. 592-604, https://doi.org/10.1002/tafs.10150.","productDescription":"13 p.","startPage":"592","endPage":"604","ipdsId":"IP-097146","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":467995,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/tafs.10150","text":"Publisher Index Page"},{"id":362144,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Lake Erie","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -84.19921875,\n              41.27780646738183\n            ],\n            [\n              -78.75,\n              41.27780646738183\n            ],\n            [\n              -78.75,\n              43.068887774169625\n            ],\n            [\n              -84.19921875,\n              43.068887774169625\n            ],\n            [\n              -84.19921875,\n              41.27780646738183\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"148","issue":"3","publishingServiceCenter":{"id":15,"text":"Madison PSC"},"noUsgsAuthors":false,"publicationDate":"2019-03-07","publicationStatus":"PW","contributors":{"authors":[{"text":"Ann Marie Gorman","contributorId":214228,"corporation":false,"usgs":false,"family":"Ann Marie Gorman","affiliations":[{"id":16232,"text":"Ohio Department of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":759401,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kraus, Richard T. 0000-0003-4494-1841 rkraus@usgs.gov","orcid":"https://orcid.org/0000-0003-4494-1841","contributorId":2609,"corporation":false,"usgs":true,"family":"Kraus","given":"Richard","email":"rkraus@usgs.gov","middleInitial":"T.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":759400,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gutowsky, Lee","contributorId":214229,"corporation":false,"usgs":false,"family":"Gutowsky","given":"Lee","email":"","affiliations":[{"id":16762,"text":"Ontario Ministry of Natural Resources and Forestry","active":true,"usgs":false}],"preferred":false,"id":759402,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vandergoot, Christopher 0000-0003-4128-3329 cvandergoot@usgs.gov","orcid":"https://orcid.org/0000-0003-4128-3329","contributorId":178356,"corporation":false,"usgs":true,"family":"Vandergoot","given":"Christopher","email":"cvandergoot@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":759403,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Yingming Zhao","contributorId":140825,"corporation":false,"usgs":false,"family":"Yingming Zhao","affiliations":[{"id":6780,"text":"Ontario Ministry of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":759404,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Knight, Carey","contributorId":214230,"corporation":false,"usgs":false,"family":"Knight","given":"Carey","affiliations":[{"id":16232,"text":"Ohio Department of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":759405,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Faust, Matt","contributorId":214231,"corporation":false,"usgs":false,"family":"Faust","given":"Matt","email":"","affiliations":[{"id":16232,"text":"Ohio Department of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":759406,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hayden, Todd","contributorId":214232,"corporation":false,"usgs":false,"family":"Hayden","given":"Todd","email":"","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":759407,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Charles Krueger","contributorId":203268,"corporation":false,"usgs":false,"family":"Charles Krueger","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":759408,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Tanzania experienced below average precipitation during 1999-2014 during two important seasons: December to February (DJF) in the south and during March to June (MAMJ) in the northeast.  We explore DJF and MAMJ precipitation in the areas with drying trends and examine their relationships with anomalous sea surface temperatures (SST) in the Indo-Pacific and corresponding circulation patterns. It is found that at seasonal time scales, precipitation in DJF and MAMJ trend areas appears inversely related to diabatic forcing in the equatorial Pacific. The dominant influence for droughts in DJF is from eastern Pacific SST while for droughts in MAMJ it is from West Pacific SST. A bivariate regression model with West Pacific and Niño3.4 region SST as predictors is found to recreate multidecadal DJF variability after the 1950s and the extreme drying in MAMJ during the 2000s. The regression model coefficients also indicate differential eastern vs. western Pacific forcing for DJF vs. MAMJ. Thus we suggest that recent La Niña-like conditions, characterized by an enhanced Pacific SST gradient due to cooling in the eastern Pacific and warming in the western Pacific, played a substantial role in Tanzania’s recent multi-season drying trends. SST change scenarios (difference between 2023-2037 and 2000-2014 means) based on CMIP5 projections and observed trends illustrate the uncertainty about future precipitation outcomes and also the potential implications of contrasting linkages to eastern vs. western Pacific SSTs. These scenarios are mainly optimistic for the DJF southern Tanzania trend area, because it appears dominated by Niño3.4 cooling at both seasonal and decadal time scales. Conversely, our scenarios are quite pessimistic for the MAMJ northeastern Tanzania trend area, because we find a dominant negative influence of warming West Pacific SST.","language":"English","publisher":"Wiley","doi":"10.1002/joc.6003","usgsCitation":"Harrison, L., Funk, C., McNally, A., Shukla, S., and Husak, G., 2019, Pacific sea surface temperature linkages with Tanzania’s multi-season drying trends: International Journal of Climate Change: Impacts and Responses, v. 39, no. 6, p. 3057-3075, https://doi.org/10.1002/joc.6003.","productDescription":"19 p.","startPage":"3057","endPage":"3075","ipdsId":"IP-101903","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":467996,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/joc.6003","text":"Publisher Index Page"},{"id":367045,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":367039,"type":{"id":15,"text":"Index Page"},"url":"https://doi.org/10.1002/joc.6003"}],"country":"Tanzania","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[33.90371,-0.95],[34.07262,-1.05982],[37.69869,-3.09699],[37.7669,-3.67712],[39.20222,-4.67677],[38.74054,-5.90895],[38.79977,-6.47566],[39.44,-6.84],[39.47,-7.1],[39.19469,-7.7039],[39.25203,-8.00781],[39.18652,-8.48551],[39.53574,-9.11237],[39.9496,-10.0984],[40.31659,-10.3171],[39.521,-10.89688],[38.42756,-11.2852],[37.82764,-11.26879],[37.47129,-11.56876],[36.77515,-11.59454],[36.51408,-11.72094],[35.3124,-11.43915],[34.55999,-11.52002],[34.28,-10.16],[33.94084,-9.69367],[33.73972,-9.41715],[32.75938,-9.2306],[32.19186,-8.93036],[31.55635,-8.76205],[31.15775,-8.59458],[30.74,-8.34],[30.2,-7.08],[29.62,-6.52],[29.41999,-5.94],[29.51999,-5.41998],[29.34,-4.49998],[29.75351,-4.45239],[30.11632,-4.09012],[30.50554,-3.56858],[30.75224,-3.35931],[30.74301,-3.03431],[30.52766,-2.80762],[30.46967,-2.41383],[30.75831,-2.28725],[30.81613,-1.69891],[30.4191,-1.13466],[30.76986,-1.01455],[31.86617,-1.02736],[33.90371,-0.95]]]},\"properties\":{\"name\":\"United Republic of Tanzania\"}}]}","volume":"39","issue":"6","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationDate":"2019-02-20","publicationStatus":"PW","contributors":{"authors":[{"text":"Harrison, Laura","contributorId":192382,"corporation":false,"usgs":false,"family":"Harrison","given":"Laura","email":"","affiliations":[],"preferred":false,"id":769796,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Funk, Chris 0000-0002-9254-6718 cfunk@usgs.gov","orcid":"https://orcid.org/0000-0002-9254-6718","contributorId":167070,"corporation":false,"usgs":true,"family":"Funk","given":"Chris","email":"cfunk@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":769795,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McNally, Amy","contributorId":145810,"corporation":false,"usgs":false,"family":"McNally","given":"Amy","email":"","affiliations":[{"id":16236,"text":"UCSB Climate Hazards Group","active":true,"usgs":false}],"preferred":false,"id":769797,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shukla, Shraddhanand","contributorId":145841,"corporation":false,"usgs":false,"family":"Shukla","given":"Shraddhanand","affiliations":[{"id":16255,"text":"Climate Hazards Group University of California Santa Barbara","active":true,"usgs":false}],"preferred":false,"id":769798,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Husak, Gregory","contributorId":145811,"corporation":false,"usgs":false,"family":"Husak","given":"Gregory","affiliations":[{"id":16236,"text":"UCSB Climate Hazards Group","active":true,"usgs":false}],"preferred":false,"id":769799,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The U.S. Geological Survey developed the Highway Runoff Database (HRDB) in cooperation with the FHWA to provide practice-ready information to meet these information needs on the local or national scale. This paper describes the datasets that are available in version 1.1 of the HRDB and demonstrates how data and statistics from the HRDB can be used with the Stochastic Empirical Loading and Dilution Model (SELDM) to simulate highway runoff. The HRDB includes 249 sites, 6,849 runoff events, and 106,869 event mean concentrations (EMCs) collected during the 1975–2017 period. It includes data from 16 States in the conterminous United States and from Hawaii. The EMCs in the HRDB include measurements for 415 different water-quality constituents. These water-quality measurements include 32,944 trace-metal; 27,496 organic; 15,684 nutrient; 13,016 physical property; 10,307 major inorganic; 6,773 sediment; and 649 other constituent values. There are large variations in the data. For example, EMCs for total suspended solids and total phosphorus range from 0.4 to 5,440 mg/L and 0.004 to 22 mg/L, respectively; geometric means range from 1.58 to 1,379 mg/L and 0.017 to 2.82 mg/L for these constituents, respectively. The example simulations indicate that risks for adverse effects of runoff can vary by orders of magnitude; the HRDB and SELDM facilitate selection of representative statistics from available datasets.</p></div></div>","language":"English","publisher":"SAGE","doi":"10.1177/0361198118822821","usgsCitation":"Granato, G., and Jones, S.C., 2019, Simulating runoff quality with the highway-runoff database and the Stochastic Empirical Loading and Dilution Model: Transportation Research Record, v. 2673, no. 1, p. 136-142, https://doi.org/10.1177/0361198118822821.","productDescription":"7 p.","startPage":"136","endPage":"142","ipdsId":"IP-101884","costCenters":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"links":[{"id":467997,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1177/0361198118822821","text":"Publisher Index Page"},{"id":437607,"rank":0,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P94VL32J","text":"USGS data release","linkHelpText":"Highway-Runoff Database (HRDB) Version 1.1"},{"id":364106,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"2673","issue":"1","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2019-01-13","publicationStatus":"PW","contributors":{"authors":[{"text":"Granato, Gregory E. 0000-0002-2561-9913","orcid":"https://orcid.org/0000-0002-2561-9913","contributorId":203250,"corporation":false,"usgs":true,"family":"Granato","given":"Gregory E.","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":763203,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, Susan C. 0000-0002-5891-5209","orcid":"https://orcid.org/0000-0002-5891-5209","contributorId":64716,"corporation":false,"usgs":false,"family":"Jones","given":"Susan","email":"","middleInitial":"C.","affiliations":[{"id":34302,"text":"Federal Highway Administration (United States)","active":true,"usgs":false}],"preferred":false,"id":763204,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

High‐head dams, such as those used for water storage or flood‐risk management, pose unique passage challenges requiring unique solutions. Systems to collect fish in dam forebays (“forebay collectors”) for transport to downstream release locations have been used at some high‐head dams in the western United States since the 1950s. Collection efficiency of these facilities has ranged from nearly 0% to 100%, suggesting the need for a better understanding of factors affecting performance in these complex environments if they are to be designed and deployed at new sites. We compiled information on environmental, structural, and performance characteristics of seven existing forebay collectors to quantify factors affecting their performance based on a meta‐analysis using a data set containing 52 separate collection estimates. Covariates included species type (steelhead Oncorhynchus mykiss, Chinook Salmon O. tshawytscha, Coho Salmon O. kisutch, and Sockeye Salmon O. nerka), collector inflow, collector entrance area, relative size of the dam forebay, and whether or not nets were used to enhance collection. We found that inflow, the use of lead nets, the size of the collector entrance area, the relative size of the dam forebay, and the interaction between collector entrance and forebay areas were significant predictors of collection performance. There was also evidence for differences between species. Chinook Salmon exhibited the lowest collection rates among the projects we examined, while steelhead collection rates were highest. These results provide guidance to design more efficient forebay collectors and improve the success of existing systems.","language":"English","publisher":"American Fisheries Society","doi":"10.1002/tafs.10146","usgsCitation":"Kock, T.J., Verretto, N.E., Ackerman, N.K., Perry, R.W., Beeman, J.W., Garello, M.C., and Fielding, S.D., 2019, Assessment of operational and structural factors influencing performance of fish collectors in forebays of high-head dams: Transactions of the American Fisheries Society, v. 148, no. 2, p. 464-479, https://doi.org/10.1002/tafs.10146.","productDescription":"16 p.","startPage":"464","endPage":"479","ipdsId":"IP-101404","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":362509,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon, Washington","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.01367187499999,\n              43.100982876188546\n            ],\n            [\n              -116.103515625,\n              43.100982876188546\n            ],\n            [\n              -116.103515625,\n              49.15296965617042\n            ],\n            [\n              -124.01367187499999,\n              49.15296965617042\n            ],\n            [\n              -124.01367187499999,\n              43.100982876188546\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"148","issue":"2","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2019-02-22","publicationStatus":"PW","contributors":{"authors":[{"text":"Kock, Tobias J. 0000-0001-8976-0230","orcid":"https://orcid.org/0000-0001-8976-0230","contributorId":214550,"corporation":false,"usgs":true,"family":"Kock","given":"Tobias","middleInitial":"J.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":760184,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Verretto, Nicholas E","contributorId":214551,"corporation":false,"usgs":false,"family":"Verretto","given":"Nicholas","email":"","middleInitial":"E","affiliations":[{"id":39067,"text":"Puget Sound Energy, Bellevue, WA","active":true,"usgs":false}],"preferred":false,"id":760185,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ackerman, Nicklaus K","contributorId":214552,"corporation":false,"usgs":false,"family":"Ackerman","given":"Nicklaus","email":"","middleInitial":"K","affiliations":[{"id":39068,"text":"Portland General Electric, Estacada, OR","active":true,"usgs":false}],"preferred":false,"id":760186,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Perry, Russell W. 0000-0003-4110-8619","orcid":"https://orcid.org/0000-0003-4110-8619","contributorId":214553,"corporation":false,"usgs":true,"family":"Perry","given":"Russell","middleInitial":"W.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":760187,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Beeman, John W","contributorId":214554,"corporation":false,"usgs":false,"family":"Beeman","given":"John","email":"","middleInitial":"W","affiliations":[{"id":39069,"text":"USGS, WFRC, CRRL, Cook, WA","active":true,"usgs":false}],"preferred":false,"id":760188,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Garello, Michael C","contributorId":214555,"corporation":false,"usgs":false,"family":"Garello","given":"Michael","email":"","middleInitial":"C","affiliations":[{"id":39070,"text":"HDR Inc., Gig Harbor, WA","active":true,"usgs":false}],"preferred":false,"id":760189,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Fielding, Scott D","contributorId":214556,"corporation":false,"usgs":false,"family":"Fielding","given":"Scott","email":"","middleInitial":"D","affiliations":[{"id":39071,"text":"U.S. Army Corps of Engineers, Portland, OR","active":true,"usgs":false}],"preferred":false,"id":760190,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

For valuing proposed public goods for which there is no current behavior, or valuing the existence or passive use values of public goods, economists can rely on stated preference methods. While there is skepticism among some economists for relying on what people say they will pay rather than what their actual behavior suggests they will pay, there is general acceptance of stated preference methods. These stated preference methods include the well-known contingent valuation method and choice experiments (sometimes called conjoint analysis). Lastly, in situations where there is neither time nor money to conduct an original revealed or stated preference study, economists can rely on benefit transfers from existing revealed preference and stated preference studies to provide rough estimates of the values of public goods such as water quality, air quality, wetlands, recreation, and endangered species.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Handbook of Regional Science","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Springer Link","doi":"10.1007/978-3-642-36203-3","isbn":"9783642362033","usgsCitation":"Loomis, J.B., Huber, C., and Richardson, L., 2019, Methods of environmental valuation, chap. <i>of</i> Handbook of Regional Science, 25 p., https://doi.org/10.1007/978-3-642-36203-3.","productDescription":"25 p.","onlineOnly":"Y","ipdsId":"IP-102704","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":365069,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Loomis, John B.","contributorId":197268,"corporation":false,"usgs":false,"family":"Loomis","given":"John","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":757238,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Huber, Christopher 0000-0001-8446-8134 chuber@usgs.gov","orcid":"https://orcid.org/0000-0001-8446-8134","contributorId":127600,"corporation":false,"usgs":true,"family":"Huber","given":"Christopher","email":"chuber@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":757236,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Richardson, Leslie","contributorId":197525,"corporation":false,"usgs":false,"family":"Richardson","given":"Leslie","affiliations":[],"preferred":false,"id":757237,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although the bulk of these have been in the literature of other disciplines, environmental toxicology and chemistry are not free from problems. While we believe that egregious misconduct such as fraud, fabrication of data, or plagiarism is rare, scientific integrity is much broader than the absence of misconduct. We are more concerned with more commonly encountered and nuanced issues such as poor reliability and bias. We review a range of topics including conflicts of interests, competing interests, some particularly challenging situations, reproducibility, bias, and other attributes of ecotoxicological studies that enhance or detract from scientific credibility. Our vision of scientific integrity encourages a self‐correcting culture that promotes scientific rigor, relevant reproducible research, transparency in competing interests, methods and results, and education.","language":"English","publisher":"Wiley","doi":"10.1002/ieam.4119","usgsCitation":"Mebane, C.A., Anne Fairbrother, Augspurger, T., Canfield, T.J., Goodfellow, W., Guiney, P., LeHuray, A.,

Northern latitudes are expected to get warmer and wetter, and while there is consensus that warming will increase thaw and methane emissions, effects of increased precipitation are uncertain. At a thawing wetland complex in Interior Alaska, we found that interactions between rain and deep soil temperatures controlled methane emissions. In rainy years, recharge from the watershed rapidly altered wetland soil temperatures, warming the top ~80 cm of soil in spring and summer and cooling it in autumn. When soils were warmed by spring rainfall, methane emissions increased by ~30%. The warm, deep soils early in the growing season likely supported both microbial and plant processes that enhanced emissions.

At Mount St. Helens (MSH), the most active volcano in the Cascades throughout the last 35&nbsp;ka, three different mafic endmembers erupted at the end of the Castle Creek period (1900–1700&nbsp;years B.P.): (1) high-field strength element (HFSE)-rich basalt enriched in K, Ti, P, and incompatible trace elements; (2) low-K olivine tholeiite (LKOT) with lower amounts of incompatible trace elements; and (3) calc-alkaline (arc-type) basaltic andesite with a typical subduction signature, i.e., enrichment in fluid-mobile large ion lithophile elements (LILE) relative to immobile high-field strength elements (HFSE). Each type has compositions projecting backwards to more primitive endmembers in the Cascades. Single units encompassing basaltic-to-basaltic andesitic compositions with intermediate trace-element abundances form two almost continuous trends towards basaltic andesite. These trends are interpreted to result from assimilation of pre-existing, more evolved, calc-alkaline material (and in one case mixing of different mafic magma types) during migration of the magmas through the crust. Most of the erupted basalts are porphyritic (10–30%) with an assemblage dominated by olivine and plagioclase and show disequilibrium textures preventing detailed reconstruction of mantle melting processes. Although typical hydrous arc basalt produced by flux melting in the mantle is absent in the eruptive products of MSH, arc-type basaltic andesite suggests its presence at depth. LKOT magmas are interpreted as decompression melts from the upper mantle, whereas HFSE-rich basalts are likely derived from the water-poor periphery of the main flux melting regime, potentially tapping a trace-element-enriched source. Primitive spinel compositions and whole-rock trace-element variations indicate at least two distinct, relatively fertile lherzolite sources for these two basalt types. Weak crustal zones associated with an old fracture system beneath MSH likely provide conduits for fast and isolated ascent of distinct batches of magma, bypassing the lower crustal mush zone. The eruption of the basalts through the upper crustal magma system and main edifice is consistent with an offset plumbing system suggested by geophysical data.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s00410-018-1544-4","usgsCitation":"Wanke, M., Bachmann, O., von Quadt Wykradt-Huchtenbruck, A., Vennemann, T.W., and Clynne, M.A., 2019, Geochemical and petrological diversity of mafic magmas from Mount St. Helens: Contributions to Mineralogy and Petrology, v. 174, 10, 25 p., https://doi.org/10.1007/s00410-018-1544-4.","productDescription":"10, 25 p.","ipdsId":"IP-088841","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":468006,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1007/s00410-018-1544-4","text":"External Repository"},{"id":462528,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","otherGeospatial":"Mount St. Helens","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.2986667033363,\n              46.29637187463061\n            ],\n            [\n              -122.2986667033363,\n              46.10268781168372\n            ],\n            [\n              -122.06937994134731,\n              46.10268781168372\n            ],\n            [\n              -122.06937994134731,\n              46.29637187463061\n            ],\n            [\n              -122.2986667033363,\n              46.29637187463061\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"174","noUsgsAuthors":false,"publicationDate":"2019-01-03","publicationStatus":"PW","contributors":{"authors":[{"text":"Wanke, Maren","contributorId":344827,"corporation":false,"usgs":false,"family":"Wanke","given":"Maren","email":"","affiliations":[{"id":27710,"text":"ETH Zurich, Switzerland","active":true,"usgs":false}],"preferred":false,"id":914828,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bachmann, Olivier","contributorId":213379,"corporation":false,"usgs":false,"family":"Bachmann","given":"Olivier","email":"","affiliations":[{"id":12483,"text":"ETH Zurich","active":true,"usgs":false}],"preferred":false,"id":914829,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"von Quadt Wykradt-Huchtenbruck, Albrecht","contributorId":344828,"corporation":false,"usgs":false,"family":"von Quadt Wykradt-Huchtenbruck","given":"Albrecht","email":"","affiliations":[{"id":27710,"text":"ETH Zurich, Switzerland","active":true,"usgs":false}],"preferred":false,"id":914831,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vennemann, Torsten W.","contributorId":190168,"corporation":false,"usgs":false,"family":"Vennemann","given":"Torsten","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":914832,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Clynne, Michael A. 0000-0002-4220-2968 mclynne@usgs.gov","orcid":"https://orcid.org/0000-0002-4220-2968","contributorId":2032,"corporation":false,"usgs":true,"family":"Clynne","given":"Michael","email":"mclynne@usgs.gov","middleInitial":"A.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":914830,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We compared small stream drainages in a semi-arid landscape with varying amounts of disturbance from oil and natural gas development to examine potential effects of this development on surface water quality. We used physical, chemical, and biological approaches to assess water quality and found several potential avenues of degradation. Surface disturbance likely contributed to elevated suspended sediment concentrations and spill history likely led to elevated stream polycyclic aromatic hydrocarbon concentrations. In combination, these environmental stressors could explain the loss of sensitive aquatic macroinvertebrate groups at sites highly affected by oil and natural gas development. Our results provide insight into advantages and disadvantages of approaches for assessing surface water quality in areas affected by oil and natural gas

Evidence suggests that introduced species with generalist diets have the potential for greatest impacts through competition and predation even though populations are often comprised of specialist individuals. The northern pike (Esox lucius), a predatory fish, has been widely introduced outside its native range for recreational fishing purposes, especially in western North America, and it has been implicated in declines and extirpations of native fishes. We synthesized over 2,900 individual northern pike diet records across 31 waterbodies from the native and introduced ranges in Alaska to quantify the extent of diet specialization and generalization relative to freshwater prey communities. To control for effects of ontogenetic diet shifts, we separately analyzed major size classes of northern pike and inferred and visualized trophic plasticity from Prey-Specific Abundance indices and ordination. Diet generalization was common in northern pike among waterbodies and usually consisted of individuals consuming macroinvertebrates. However, when available, individual northern pike diets showed specialization on fishes, amphibians, small mammals, and dragonflies. The reliance on macroinvertebrate prey by northern pike from small, isolated lakes in the native and invasive ranges suggests that dietary plasticity facilitates persistence of these predators in the absence of preferred fish prey. Broadly, this synthesis supports the hypothesis that trophic plasticity and diet generalization widely occur among invasive and native populations of northern pike which is likely to enhance the probability of introduction success, exacerbate their environmental impacts, and complicate management of this potentially invasive freshwater predator.","language":"English","publisher":"Springer","doi":"10.1007/s10530-018-1909-7","usgsCitation":"Cathcart, C.N., Dunker, K.J., Quinn, T.P., Sepulveda, A.J., von Hippel, F.A., Wizik, A., Young, D.B., and Westley, P.A., 2019, Trophic plasticity and the invasion of a renowned piscivore: A diet synthesis of northern pike (Esox lucius) from the native and introduced ranges in Alaska, U.S.A.: Biological Invasions, v. 21, no. 4, p. 1379-1392, https://doi.org/10.1007/s10530-018-1909-7.","productDescription":"14 p.","startPage":"1379","endPage":"1392","ipdsId":"IP-103289","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":361977,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -159.521484375,\n              57.961503094284794\n            ],\n            [\n              -146.0302734375,\n              57.961503094284794\n            ],\n            [\n              -146.0302734375,\n              62.36999628130772\n            ],\n            [\n              -159.521484375,\n              62.36999628130772\n            ],\n            [\n              -159.521484375,\n              57.961503094284794\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"21","issue":"4","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2019-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Cathcart, C.

Environments of the shelf are dominated by the southward-flowing Leeuwin Current, which impacts near-surface circulation and influences biogeographic ranges of Indo-Pacific warm-water foraminifera. Analyses of outer ramp to upper slope sediments (127–264 m water depth) at four different sites (some with replicates) revealed 185 benthic species. A shift from benthic to planktonic foraminifera was accompanied by the decrease of “larger” benthic foraminifera below the lowermost euphotic zone. Fisher α and proportions of buliminid and textularid taxa increased with water depth, as miliolids and rotalids decreased in proportion. Cluster analyses on the 125–250 μm and 250–850 μm size fractions revealed distinct assemblages, with the former distinguishing between deeper and shallower sites, and the latter distinguishing between the Carnarvon Ramp-site in the south and the three sites on the Northwestern Shelf (NWS). The assemblage shift with depth was likely caused by rapidly changing physical conditions in the upper thermocline. The assemblage differences between the NWS and the Carnarvon Ramp indicate limited horizontal transport and migration rates on the outer shelf below the influence of the Leeuwin Current. Similarity in bottom-water temperature at the studied sites indicates that water mass characteristics, biogeographic history or possibly diversity in benthic shelf habitats rather than temperature and depth are responsible for differences between the two regions.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Geologic problem solving with microfossils IV","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Society for Sedimentary Geology","doi":"10.2110/sepmsp.111.05","usgsCitation":"Christian Haller, Hallock, P., Albert C.

It is considered a fluvial specialist and as such, there are concerns that the increasing demands being placed upon the water resources of central Texas by growing human populations have the potential to negatively impact Guadalupe Bass populations. Therefore, this study assessed the relationship between Guadalupe Bass growth, feeding ecology, and streamflow. Sagittal otoliths were removed from Guadalupe Bass collected from throughout their range during 2015-2017 and used to estimate the age and back-calculate the growth trajectory of each individual. Additionally, young-of-year (YOY) Guadalupe Bass were collected every 10-14 days from two second-order streams, the North Llano River and South Llano River, in the Colorado Basin on the Edwards Plateau. Stomach contents of these individuals were identified and the effect of streamflow on the occurrence of the taxa comprising the stomach contents assessed.&nbsp;</span></p><p><span>Guadalupe Bass growth was greater in the Colorado and Guadalupe River basins, independent of stream order, and tended to increase with increasing stream order within a basin. Growth was higher in higher stream orders and during years with stable and lower spring and summer monthly median flows, lower minimum and maximum flows, slower rise and fall rates, and higher baseflows. Growth was not influenced by years with higher monthly median flows in winter. These results would seem to contradict previous research, but more likely represent a fuller picture of how Guadalupe Bass respond to flow conditions. The disagreement between the current study and past studies seem to be attributable, at least in part, to the fact that previous studies were conducted during a period of extensive drought, while the current study was conducted during relatively wet conditions. Taken together with previous studies, the current study suggests that Guadalupe Bass growth is sensitive to flow conditions and is lower in years with flow conditions that fall outside a basin- and stream order-specific optimal range for the species.</span></p><p><span>A total of 21 unique taxonomic groups were recovered from the stomachs of YOY Guadalupe Bass collected from the North Llano River and South Llano River. Aquatic insects, especially larval mayflies (Ephemeroptera), damselflies (Odanata: Zygoptera), and caddisflies (Trichoptera), were the most frequently encountered taxa. While there was no difference between the two rivers in stomach content composition, there was a strong longitudinal gradient in both systems with aquatic insects predominating at upstream sample sites and fishes being more common at downstream sites. Stream discharge during the 24 hours prior to collection did not have any influence on the probability of a taxa being found in Guadalupe Bass stomachs.&nbsp;</span><br><br><span>The results of this study support efforts to manage Guadalupe Bass populations at a sub-watershed scale and suggests that populations occupying the same stream order within a basin are likely to have similar responses to annual flow conditions. In addition, these results indicate that the lower Colorado River population may inhabit a unique set of conditions that has supported the development of a trophy Guadalupe Bass fishery. Further, this study highlights the need to incorporate a sufficient range of annual flow conditions to ensure that the influence of stream flow on fish growth is adequately assessed. While interannual variation in growth rates seem to be capable of serving as a proxy for recruitment and year-class strength, long-term monitoring of recruitment paired with assessment of growth is necessary to further clarify the relationship between population density, flow regime, recruitment and growth and allow the construction of predictive models.</span><br><br><br></p>","language":"English","publisher":"U.S. Fish & Wildlife Service","usgsCitation":"Grabowski, T.B., Williams, H.M., Verble, R., Pease, A., and Pease, J., 2019, Guadalupe Bass flow-ecology relationships; with emphasis on the impact of flow on recruitment: Cooperator Science Series 144-2019, 45 p.","productDescription":"45 p.","ipdsId":"IP-112364","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":426896,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":426893,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.fws.gov/media/guadalupe-bass-flow-ecology-relationships-emphasis-impact-flow-recruitment"}],"country":"United States","state":"Texas","otherGeospatial":"Edwards Plateau","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -101.5545656225707,\n              32.58046976338021\n            ],\n            [\n              -101.5545656225707,\n              28.46527294922906\n            ],\n            [\n              -95.89656252117818,\n              28.46527294922906\n            ],\n            [\n              -95.89656252117818,\n              32.58046976338021\n            ],\n            [\n              -101.5545656225707,\n              32.58046976338021\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Grabowski, Timothy B. 0000-0001-9763-8948 tgrabowski@usgs.gov","orcid":"https://orcid.org/0000-0001-9763-8948","contributorId":4178,"corporation":false,"usgs":true,"family":"Grabowski","given":"Timothy","email":"tgrabowski@usgs.gov","middleInitial":"B.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":831360,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Williams, Heather M.","contributorId":272025,"corporation":false,"usgs":false,"family":"Williams","given":"Heather","email":"","middleInitial":"M.","affiliations":[{"id":36331,"text":"Texas Tech University","active":true,"usgs":false}],"preferred":false,"id":831361,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Verble, Robin","contributorId":272026,"corporation":false,"usgs":false,"family":"Verble","given":"Robin","email":"","affiliations":[{"id":37501,"text":"Missouri University of Science and Technology","active":true,"usgs":false}],"preferred":false,"id":831362,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pease, Allison","contributorId":272027,"corporation":false,"usgs":false,"family":"Pease","given":"Allison","affiliations":[{"id":36331,"text":"Texas Tech University","active":true,"usgs":false}],"preferred":false,"id":831363,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pease, Jessica","contributorId":272028,"corporation":false,"usgs":false,"family":"Pease","given":"Jessica","affiliations":[{"id":56336,"text":"Oregon Cooperative Fish and Wildlife Research Unit, Oregon State University","active":true,"usgs":false}],"preferred":false,"id":831364,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

From 2000 to 2015, South Dakota Game, Fish and Parks spent &gt;$5.6 million to manage damages caused by Canada geese to agricultural crops (primarily soybeans) in South Dakota, USA. For the purpose of developing a repellent application strategy for nonlethal goose damage management, we comparatively evaluated the width of anthraquinone applications (i.e., 9.4 L Flight Control<sup>®<span>&nbsp;</span></sup>Plus goose repellent/ha [active ingredient: 50% 9,10-anthraquinone] at 0–36 m versus 0–73 m perpendicular to the edge of wetlands in 2014), the timing of the first repellent application (i.e., 9.4 L Flight Control Plus goose repellent/ha at 50% versus 75% seedling emergence in 2015), the yield of soybeans (<i>Glycine max</i>) within repellent-treated and untreated subplots, and anthraquinone chemical residues in Day County, South Dakota. Soybean yield was greater in subplots 73 m from the water’s edge than that in the 36-m subplots (<i>P</i><span>&nbsp;</span>&lt; 0.02). Among subplots first sprayed at 50% seedling emergence, soybean yield was greater at 73 m and 82 m than that at 36 m (<i>P</i><span>&nbsp;</span>&lt; 0.005). In contrast, we observed no difference in yield at 36 m, 73 m, or 82 m in the subplots first sprayed at 72% seedling emergence (<i>P</i><span>&nbsp;</span>&gt; 0.09). We therefore conclude that goose damages were effectively managed in subplots first sprayed at 72% seedling emergence. Anthraquinone residues averaged 674 and 629 ppm anthraquinone upon the first application of the repellent (June to July), 22 and 35 ppm anthraquinone in the mid-season hay (August to September), and 36 and 28 ppb anthraquinone in the harvested seed (October to November) in 2014 and 2015, respectively. Our results suggest that a 73-m bandwidth of anthraquinone-based repellents first applied at approximately 72% or 65–85% seedling emergence can protect soybeans from Canada goose depredation.</p></div><div id=\"recommended_citation\" class=\"element\"><br></div>","language":"English","publisher":"Jack H.
