In January 2015, 11.4&nbsp;M&nbsp;L (million liters) of wastewater (300&nbsp;g/L TDS) from oil production in the Williston Basin was reported to have leaked from a pipeline, spilling into Blacktail Creek, North Dakota. Geochemical and biological samples were collected in February and June 2015 to identify geochemical signatures of spilled wastewaters as well as biological responses along a 44-km river reach. February water samples had elevated chloride (1030&nbsp;mg/L) and bromide (7.8&nbsp;mg/L) downstream from the spill, compared to upstream levels (11&nbsp;mg/L and &lt;&nbsp;0.4&nbsp;mg/L, respectively). Lithium (0.25&nbsp;mg/L), boron (1.75&nbsp;mg/L) and strontium (7.1&nbsp;mg/L) were present downstream at 5–10 times upstream concentrations. Light hydrocarbon measurements indicated a persistent thermogenic source of methane in the stream. Semi-volatile hydrocarbons indicative of oil were not detected in filtered samples but low levels, including tetramethylbenzenes and di-methylnaphthalenes, were detected in unfiltered water samples downstream from the spill. Labile sediment-bound barium and strontium concentrations (June 2015) were higher downstream from the Spill Site. Radium activities in sediment downstream from the Spill Site were up to 15 times the upstream activities and, combined with Sr isotope ratios, suggest contributions from the pipeline fluid and support the conclusion that elevated concentrations in Blacktail Creek water are from the leaking pipeline. Results from June 2015 demonstrate the persistence of wastewater effects in Blacktail Creek several months after remediation efforts started. Aquatic health effects were observed in June 2015; fish bioassays showed only 2.5% survival at 7.1&nbsp;km downstream from the spill compared to 89% at the upstream reference site. Additional potential biological impacts were indicated by estrogenic inhibition in downstream waters. Our findings demonstrate that environmental signatures from wastewater spills are persistent and create the potential for long-term environmental health effects.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2016.11.157","usgsCitation":"Cozzarelli, I.M., Skalak, K., Kent, D., Engle, M.A., Benthem, A.J., Mumford, A.C., Haase, K.B., Farag, A.M., Harper, D., Nagel, S.C., Iwanowicz, L., Orem, W.H., Akob, D.M., Jaeschke, J.B., Galloway, J.M., Kohler, M., Stoliker, D., and Jolly, G., 2017, Environmental signatures and effects of an oil and gas wastewater spill in the Williston Basin, North Dakota: Science of the Total Environment, v. 579, p. 1781-1793, https://doi.org/10.1016/j.scitotenv.2016.11.157.","productDescription":"13 p.","startPage":"1781","endPage":"1793","ipdsId":"IP-080154","costCenters":[{"id":436,"text":"National Research Program -

Most existing host-parasite databases focus on particular host taxa, do not distinguish final from intermediate hosts, and lack parasite life-history information. We summarized the known life cycles of trophically transmitted parasitic acanthocephalans, cestodes, and nematodes. For 973 parasite species, we gathered information from the literature on the hosts infected at each stage of the parasite life cycle (8510 host-parasite species associations), what parasite stage is in each host, and whether parasites need to infect certain hosts to complete the life cycle. We also collected life-history data for these parasites at each life cycle stage, including 2313 development time measurements and 7660 body size measurements. The result is the most comprehensive data summary available for these parasite taxa. In addition to identifying gaps in our knowledge of parasite life cycles, these data can be used to test hypotheses about life cycle evolution, host specificity, parasite life-history strategies, and the roles of parasites in food webs.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1002/ecy.1680","usgsCitation":"Benesh, D.P., Lafferty, K.D., and Kuris, A., 2017, A life cycle database for parasitic acanthocephalans, cestodes, and nematodes: Ecology, v. 98, no. 3, p. 882-882, https://doi.org/10.1002/ecy.1680.","productDescription":"1 p.","startPage":"882","endPage":"882","ipdsId":"IP-080795","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":470058,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ecy.1680","text":"Publisher Index Page"},{"id":336114,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"98","issue":"3","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58b002c5e4b01ccd54fb27c1","contributors":{"authors":[{"text":"Benesh, Daniel P.","contributorId":181950,"corporation":false,"usgs":false,"family":"Benesh","given":"Daniel","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":670122,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lafferty, Kevin D. 0000-0001-7583-4593 klafferty@usgs.gov","orcid":"https://orcid.org/0000-0001-7583-4593","contributorId":1415,"corporation":false,"usgs":true,"family":"Lafferty","given":"Kevin","email":"klafferty@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":670121,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kuris, Armand","contributorId":181951,"corporation":false,"usgs":false,"family":"Kuris","given":"Armand","affiliations":[],"preferred":false,"id":670123,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These tests were performed by using the MatLAB implementation of PRISM, which is equivalent to its public release version in Java language. Systematic comparisons were made in time and frequency domains of records processed in PRISM and BAP, and in CSMIP, by using a set of representative input motions with varying resolutions, frequency content, and amplitudes. Although the details of strong-motion records vary among the processing procedures, there are only minor differences among the waveforms for each component and within the frequency passband common to these procedures. A comprehensive statistical evaluation considering more than 1,800 ground-motion components demonstrates that differences in peak amplitudes of acceleration, velocity, and displacement time series obtained from PRISM and CSMIP processing are equal to or less than 4 percent for 99 percent of the data, and equal to or less than 2 percent for 96 percent of the data.

The initial hydrogeologic and geochemical characterization of two arroyos located within the Pojoaque River Basin was performed in 2014 and 2015 in cooperation with the Bureau of Reclamation to evaluate the potential suitability of these two arroyos as sites for managed aquifer recharge through surface infiltration.</p><p>The selected reaches were high-gradient (average 3.0–3.5 percent) braided channels filled with unconsolidated sand and gravel-sized deposits that were generally 30–50 feet thick. Saturation was not observed in the unconsolidated channel sands in four subsurface borings but was found at 7–60 feet below the contact between the unconsolidated channel sands and the bedrock. The poorly to well-cemented alluvial deposits that make up the bedrock underlying the unconsolidated channel material is the Tesuque Formation. The individual beds of the Tesuque Formation are reported to be highly heterogeneous and anisotropic, and the bedrock at the site was observed to have variable moisture and large changes in lithology. Surface electrical-resistivity geophysical survey methods showed a sharp contrast between the electrically resistive unconsolidated channel sands and the highly conductive bedrock; however, because of the high conductivity, the resistivity methods were not able to image the water table or preferential flow paths (if they existed) in the bedrock.</p><p>Infiltration rates measured by double-ring and bulk infiltration tests on a variety of channel morphologies in the study reaches were extremely large (9.7–94.5 feet per day), indicating that the channels could potentially accommodate as much as 6.6 cubic feet per second of applied water without generating surface runoff out of the reach; however, the small volume available for storage in the unconsolidated channel sands (about 410 acre-feet in the east arroyo and about 190 acre-feet in the west arroyo) and the potential for the infiltrating water to preferentially flow over the bedrock contact and out of the reach present a challenge for storing water. Although a detailed assessment of the infiltration rate of the Tesuque Formation is beyond the scope of this investigation, one double-ring infiltrometer test was conducted on an outcrop, resulting in an estimated infiltration rate of about 4 feet per day.</p><p>The shallow groundwater observed in this investigation was determined to be recharged locally on the basis of groundwater elevations and geochemical and isotopic signatures. The channel sands and shallow bedrock were observed to be weathered, indicating contact with oxic groundwater following deposition. This observation was supported by whole-rock elemental analysis and mineralogy of several core samples. The downward groundwater gradient between the shallow wells and those wells screened at greater depths suggests that the shallow groundwater is recharged by local precipitation and has the potential to migrate to the deeper aquifer units. The two age-dating tracers measured in this investigation, however, demonstrate that the shallow groundwater flow paths are very slow and that the deeper flow paths are likely part of a larger regional system.</p><p>The composition of the shallow, native groundwater suggests that storing water diverted from the Rio Grande is not likely to leach constituents of concern that would cause the stored water to exceed health-based U.S. Environmental Protection Agency Maximum Contaminant Levels.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

Despite vacancies in our scientist ranks exceeding 20 percent, our research, training, and teaching portfolio was full and we graduated 93 students and published 398 manuscripts primarily focused on addressing the real conservation challenges of our cooperators. As I’ve stated before, our mission is our legacy: meeting the actionable science needs of our cooperators, providing them technical guidance and assistance in interpreting and applying new advances in science, and developing the future workforce through graduate education and mentoring. Our scientists and the manner in which they approach our mission continue to inspire me. The most rewarding part of my job is meeting and engaging with the students they recruit—the conservation professionals of the future. I cannot help but feel uplifted after discussions with and presentations by these young men and women. Personally, I owe my place in the profession today to the mentoring I received as a CRU student, and today’s CRU scientists have raised the bar. It gives me hope for the future of conservation, and added motivation to see our vacancies filled so that we can expand our portfolio.</p><p>The National Cooperators’ Coalition has been active and is strategically working to build support on our behalf. Sincere thanks to the American Fisheries Society, the Association of Fish and Wildlife Agencies, the Boone and Crockett Club, the National Association of University Fish and Wildlife Programs, the Wildlife Management Institute, and The Wildlife Society for their efforts and those of their affiliated members.</p><p>We co-sponsored a workshop at the 2016 North American Wildlife and Natural Resources Conference along with the American Fisheries Society, the Association of Fish and Wildlife Agencies, the Wildlife Management Institute, and The Wildlife Society, titled “Barriers and Bridges in Reconnecting Natural Resources Science and Management.” The workshop was well received and we have been asked to continue the dialogue with a second workshop in 2017. It was evident during the workshop that the CRU is viewed by our cooperators as an important and essential linkage between academia and practitioners. This is testament to the legacy of the CRU Program and the foundation it is built upon. In this Year in Review report, you will find details on staffing, vacancies, research funding, and other pertinent information. You will also see snapshots of CRU projects with information on how results have been or are being applied by cooperators. That is the essence of what we do: science that matters.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/cir1424","isbn":"978-1-4113-4106-7","usgsCitation":"Organ, J.F., Thompson, J.D., Dennerline, D.E., and Childs, D.E., 2017, Cooperative Fish and Wildlife Research Units Program—2016 year in review: U.S. Geological Survey Circular 1424, 44 p., https://doi.org/10.3133/cir1424.","productDescription":"Report: vi, 44 p.; Companion File","numberOfPages":"52","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-080577","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":340050,"rank":5,"type":{"id":22,"text":"Related Work"},"url":"https://pubs.usgs.gov/publication/fs20173022","text":"Fact Sheet 2017–3022","linkHelpText":"- Cooperative Fish and Wildlife Research Units—A Model Partnership Program"},{"id":340051,"rank":6,"type":{"id":22,"text":"Related Work"},"url":"https://pubs.usgs.gov/publication/cir1427","text":"Circular 1427","linkHelpText":"- U.S. Geological Survey Cooperative Fish and Wildlife Research Units Program—2016 Research Abstracts"},{"id":334820,"rank":3,"type":{"id":22,"text":"Related Work"},"url":"https://pubs.usgs.gov/publication/cir1420","text":"Circular 1420","linkHelpText":"Cooperative Fish and Wildlife Research Units Program—2015 Year in Review"},{"id":334818,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1424/coverthb.jpg"},{"id":334821,"rank":4,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/publication/gip170","text":"General Information Product  postcard - ","linkHelpText":"Cooperative Fish and Wildlife Research Units Program—2016 Year in Review"},{"id":334819,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1424/circ1424.pdf","text":"Report","size":"41.7 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Circ 1424"}],"contact":"<p>Cooperative Fish and Wildlife Research Units Program<br> U.S. Geological Survey <br> 12201 Sunrise Valley Drive <br> Reston, VA 20192 <br> <a href=\"http://www.coopunits.org/\" data-mce-href=\"http://www.coopunits.org/\">http://www.coopunits.org/</a></p>","tableOfContents":"<ul><li>Chief’s Message</li><li>Background</li><li>CRU Mission and Facts</li><li>Training the Conservation Workforce</li><li>Leveraging Resources</li><li>Outreach and Training</li><li>Budget and Staffing</li><li>Current (2017) Vacancies</li><li>Science Themes</li><li>Where Are They Now?</li><li>Accolades</li><li>Professional Services</li><li>Joe Margraf Retirement</li><li>North American Conference Science and Management Workshop</li><li>National Cooperators’ Coalition (NCC)</li><li>2016 CRU All-Hands Meeting in Santa Fe, New Mexico</li></ul>","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"publishedDate":"2017-02-22","noUsgsAuthors":false,"publicationDate":"2017-02-22","publicationStatus":"PW","scienceBaseUri":"58aeb137e4b01ccd54f9ee0a","contributors":{"authors":[{"text":"Organ, John F. 0000-0002-0959-0639 jorgan@usgs.gov","orcid":"https://orcid.org/0000-0002-0959-0639","contributorId":152568,"corporation":false,"usgs":true,"family":"Organ","given":"John","email":"jorgan@usgs.gov","middleInitial":"F.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":false,"id":655693,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thompson, John D. 0000-0003-4113-2440 jthompson@usgs.gov","orcid":"https://orcid.org/0000-0003-4113-2440","contributorId":177395,"corporation":false,"usgs":true,"family":"Thompson","given":"John","email":"jthompson@usgs.gov","middleInitial":"D.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":false,"id":655696,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dennerline, Donald E. 0000-0001-8345-315X don_dennerline@usgs.gov","orcid":"https://orcid.org/0000-0001-8345-315X","contributorId":177394,"corporation":false,"usgs":true,"family":"Dennerline","given":"Donald","email":"don_dennerline@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":false,"id":655694,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Childs, Dawn E. 0000-0001-8544-9517 dchilds@usgs.gov","orcid":"https://orcid.org/0000-0001-8544-9517","contributorId":177334,"corporation":false,"usgs":true,"family":"Childs","given":"Dawn","email":"dchilds@usgs.gov","middleInitial":"E.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":false,"id":655695,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

A 3 week field study was conducted in approximately 1.5 m water depth on the reef flat at Ningaloo Reef, Western Australia, to quantify the cross-reef hydrodynamics and suspended sediment dynamics over the large bottom roughness (∼20–40 cm) at the site. A logarithmic mean current profile consistently developed above the height of the roughness; however, the flow was substantially reduced below the height of the roughness (canopy region). Shear velocities inferred from the logarithmic profile and Reynolds stresses measured at the top of the roughness, which are traditionally used in predictive sediment transport formulations, were similar but much larger than that required to suspend the relatively coarse sediment present at the bed. Importantly, these stresses did not represent the stresses imparted on the sediment measured in suspension and are therefore not relevant to the description of suspended sediment transport in systems with large bottom roughness. Estimates of the bed shear stresses that accounted for the reduced near-bed flow in the presence of large roughness vastly improved the relationship between the predicted and observed grain sizes that were in suspension. Thus, the impact of roughness, not only on the overlying flow but also on bed stresses, must be accounted for to accurately estimate suspended sediment transport in regions with large bottom roughness, a common feature of many shallow coastal ecosystems.","language":"English","publisher":"AGU Publications","doi":"10.1002/2016JC011755","usgsCitation":"Pomeroy, A., Lowe, R.J., Ghisalberti, M., Storlazzi, C.D., Symonds, G., and Roelvink, D., 2017, Sediment transport in the presence of large reef bottom roughness: Journal of Geophysical Research C: Oceans, v. 122, no. 2, p. 1347-1368, https://doi.org/10.1002/2016JC011755.","productDescription":"22 p.","startPage":"1347","endPage":"1368","ipdsId":"IP-073705","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":470059,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2016jc011755","text":"Publisher Index Page"},{"id":335998,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"122","issue":"2","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2017-02-20","publicationStatus":"PW","scienceBaseUri":"58aeb138e4b01ccd54f9ee0e","contributors":{"authors":[{"text":"Pomeroy, Andrew","contributorId":182033,"corporation":false,"usgs":false,"family":"Pomeroy","given":"Andrew","affiliations":[],"preferred":false,"id":670337,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lowe, Ryan J.","contributorId":152265,"corporation":false,"usgs":false,"family":"Lowe","given":"Ryan","email":"","middleInitial":"J.","affiliations":[{"id":6986,"text":"Stanford University","active":true,"usgs":false}],"preferred":false,"id":670338,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ghisalberti, Marco","contributorId":182034,"corporation":false,"usgs":false,"family":"Ghisalberti","given":"Marco","email":"","affiliations":[],"preferred":false,"id":670339,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Storlazzi, Curt D. 0000-0001-8057-4490 cstorlazzi@usgs.gov","orcid":"https://orcid.org/0000-0001-8057-4490","contributorId":140584,"corporation":false,"usgs":true,"family":"Storlazzi","given":"Curt","email":"cstorlazzi@usgs.gov","middleInitial":"D.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":670336,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Symonds, Graham","contributorId":182035,"corporation":false,"usgs":false,"family":"Symonds","given":"Graham","email":"","affiliations":[],"preferred":false,"id":670340,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Roelvink, Dano","contributorId":139950,"corporation":false,"usgs":false,"family":"Roelvink","given":"Dano","email":"","affiliations":[{"id":13328,"text":"UNESCO-IHE","active":true,"usgs":false}],"preferred":false,"id":670341,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Less attention has been placed on distant tsunamis, where evacuations unfold over several hours, are often dominated by vehicle use and are managed by public safety officials. Traditional traffic simulation models focus on estimating clearance times but often overlook the influence of varying population demand, alternative modes, background traffic, shadow evacuation, and traffic management alternatives. These factors are especially important for island communities with limited egress options to safety. We use the coastal community of Balboa Island, California (USA), as a case study to explore the range of potential clearance times prior to wave arrival for a distant tsunami scenario. We use a first-in–first-out queuing simulation environment to estimate variations in clearance times, given varying assumptions of the evacuating population (demand) and the road network over which they evacuate (supply). Results suggest clearance times are less than wave arrival times for a distant tsunami, except when we assume maximum vehicle usage for residents, employees, and tourists for a weekend scenario. A two-lane bridge to the mainland was the primary traffic bottleneck, thereby minimizing the effect of departure times, shadow evacuations, background traffic, boat-based evacuations, and traffic light timing on overall community clearance time. Reducing vehicular demand generally reduced clearance time, whereas improvements to road capacity had mixed results. Finally, failure to recognize non-residential employee and tourist populations in the vehicle demand substantially underestimated clearance time.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s11069-016-2655-8","usgsCitation":"Henry, K., Wood, N.J., and Frazier, T.G., 2017, Influence of road network and population demand assumptions in evacuation modeling for distant tsunamis: Natural Hazards, v. 85, no. 3, p. 1665-1687, https://doi.org/10.1007/s11069-016-2655-8.","productDescription":"23 p.","startPage":"1665","endPage":"1687","ipdsId":"IP-075676","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":343280,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"Balboa Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.9019045829773,\n              33.603056937190075\n            ],\n            [\n              -117.88405179977417,\n              33.603056937190075\n            ],\n            [\n              -117.88405179977417,\n              33.609883739325674\n            ],\n            [\n              -117.9019045829773,\n              33.609883739325674\n            ],\n            [\n              -117.9019045829773,\n              33.603056937190075\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"85","issue":"3","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2016-11-11","publicationStatus":"PW","scienceBaseUri":"595ca914e4b0d1f9f054ca16","contributors":{"authors":[{"text":"Henry, Kevin 0000-0001-9314-2531 khenry@usgs.gov","orcid":"https://orcid.org/0000-0001-9314-2531","contributorId":176934,"corporation":false,"usgs":true,"family":"Henry","given":"Kevin","email":"khenry@usgs.gov","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":703287,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wood, Nathan J. 0000-0002-6060-9729 nwood@usgs.gov","orcid":"https://orcid.org/0000-0002-6060-9729","contributorId":3347,"corporation":false,"usgs":true,"family":"Wood","given":"Nathan","email":"nwood@usgs.gov","middleInitial":"J.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":703288,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Frazier, Tim G.","contributorId":64793,"corporation":false,"usgs":true,"family":"Frazier","given":"Tim","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":703289,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The U.S. Geological Survey (USGS) has operated a high-frequency (15-minute sampling interval) water-quality monitoring network in San Francisco Bay since the late 1980s (Buchanan and others, 2014). This network includes 19 stations at which sustained measurements have been made in the bay; currently, 8 stations are in operation (fig. 1). All eight stations are equipped with specific conductance (which can be related to salinity) and water-temperature sensors. Water quality in the bay constantly changes as ocean tides force seawater in and out of the bay, and river inflows—the most significant coming from the delta—vary on time scales ranging from those associated with storms to multiyear droughts. This monitoring network was designed to observe and characterize some of these changes in the bay across space and over time. The data demonstrate a high degree of variability in both specific conductance and temperature at time scales from tidal to annual and also reveal longer-term changes that are likely to influence overall environmental health in the bay.<br></p><p>In water year (WY) 2015 (October 1, 2014, through September 30, 2015), as in the preceding water year (Downing-Kunz and others, 2015), the high-frequency measurements revealed record-high values of specific conductance and water temperature at several stations during a period of reduced freshwater inflow from the delta and other tributaries because of persistent, severe drought conditions in California. This report briefly summarizes observations for WY 2015 and compares them to previous years that had different levels of freshwater inflow.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20171022","issn":"2331-1258 (online)","usgsCitation":"Work, P.A., Downing-Kunz, M.A., and Livsey, D., 2017, Record-high specific conductance and water temperature in San Francisco Bay during water year 2015: U.S. Geological Survey Open-File Report 2017–1022, 4 p., https://doi.org/10.3133/ofr20171022.","productDescription":"4 p.","numberOfPages":"4","onlineOnly":"Y","ipdsId":"IP-079162","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true}],"links":[{"id":335947,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2017/1022/coverthb.jpg"},{"id":335948,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2017/1022/ofr20171022.pdf","text":"Report","size":"1.1 MB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2017-1022"}],"country":"United States","state":"California","otherGeospatial":"Sacramento-San Joaquin River Delta, San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.9,\n              37.4\n            ],\n            [\n              -122.5,\n              37.4\n            ],\n            [\n              -122.5,\n              38.1\n            ],\n            [\n              -121.9,\n              38.1\n            ],\n            [\n              -121.9,\n              37.4\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"https://mail.google.com/mail/?view=cm&amp;fs=1&amp;tf=1&amp;to=dc_ca@usgs.gov\" data-mce-href=\"https://mail.google.com/mail/?view=cm&amp;fs=1&amp;tf=1&amp;to=dc_ca@usgs.gov\">Director</a>, California Water Science Center<br>U.S. Geological Survey<br>6000 J Street, Placer Hall<br>Sacramento, CA 95819</p><p><a href=\"http://ca.water.usgs.gov/\" data-mce-href=\"http://ca.water.usgs.gov\">http://ca.water.usgs.gov</a></p>","tableOfContents":"<ul><li>Abstract</li><li>Instrumentation and Data Collection<br></li><li>Water Year 2015 Records<br></li><li>Annual Mean Values and Relation to Freshwater Inflow</li><li>References Cited</li></ul>","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"publishedDate":"2017-02-22","noUsgsAuthors":false,"publicationDate":"2017-02-22","publicationStatus":"PW","scienceBaseUri":"58aeb139e4b01ccd54f9ee12","contributors":{"authors":[{"text":"Work, Paul A. 0000-0002-2815-8040 pwork@usgs.gov","orcid":"https://orcid.org/0000-0002-2815-8040","contributorId":168561,"corporation":false,"usgs":true,"family":"Work","given":"Paul","email":"pwork@usgs.gov","middleInitial":"A.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":669845,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Downing-Kunz, Maureen A. 0000-0002-4879-0318 mdowning-kunz@usgs.gov","orcid":"https://orcid.org/0000-0002-4879-0318","contributorId":3690,"corporation":false,"usgs":true,"family":"Downing-Kunz","given":"Maureen","email":"mdowning-kunz@usgs.gov","middleInitial":"A.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":669846,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Livsey, Daniel N. 0000-0002-2028-6128 dlivsey@usgs.gov","orcid":"https://orcid.org/0000-0002-2028-6128","contributorId":181870,"corporation":false,"usgs":true,"family":"Livsey","given":"Daniel","email":"dlivsey@usgs.gov","middleInitial":"N.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":669847,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Continuous streamflow records at four USGS streamflow-gaging stations were compared to quantify differences in streamflow magnitude between upstream and downstream reaches of the lower Trinity River. Water-quality conditions were characterized from discrete nutrient and sedi­ment samples collected over a range of hydrologic conditions at USGS streamflow-gaging station 08067252 Trinity River at Wallisville, Tex. (hereinafter referred to as the “Wallisville site”), approximately 4 river miles upstream from where the Trinity River enters Galveston Bay.</p><p>Based on streamflow records, annual mean outflow from Livingston Dam into the lower Trinity River was 2,240 cubic feet per second (ft<sup>3</sup>/s) in 2014 and 22,400 ft<sup>3</sup>/s in 2015, the second lowest and the highest, respectively, during the entire period of record (1966–2015). During this study, only about 54 percent of the total volume measured at upstream sites was accounted for at the Wallisville site as the Trinity River enters Galveston Bay. This difference in water volumes between upstream sites and the Wallisville site indicates that at high flows a large part of the volume released from Lake Livingston does not reach Galveston Bay through the main channel of the Trinity River. These findings indicate that water likely flows into wetlands and water bodies surrounding the main channel of the Trinity River before reaching the Wallisville site and is being stored or discharged through other channels that flow directly into Galveston Bay.</p><p>To characterize suspended-sediment concentrations and loads in Trinity River inflow to Galveston Bay, a regression model was developed to estimate suspended-sediment concentrations by using acoustic backscatter data as a surrogate. The model yielded an adjusted coefficient of determination value of 0.92 and a root mean square error of 1.65 milligrams per liter (mg/L). The mean absolute percentage error between measured and estimated suspended-sediment concentration was 35 percent. During this study, estimated suspended-sediment concentrations ranged from 2 to 701 mg/L, with a mean of 97 mg/L. Suspended-sediment concentrations varied in response to changes in discharge, with peak suspended-sediment concentrations occurring 1 to 2 days before the peak discharge for each event. The total suspended-sediment load at the Wallisville site during May 2014–December 2015 was approximately 2,200,000 tons, with a minimum monthly suspended-sediment load of 100 tons in October 2014 and a maximum monthly load of 441,000 tons in November 2015.</p><p>Results from nutrient samples collected at the Wallisville site indicate that total nitrogen and total phosphorus concen­trations fluctuated at a similar rate, with the highest nutrient concentrations occurring during periods of high flow corresponding to releases from Lake Livingston. The mean concen­trations of total nitrogen and total phosphorus were approxi­mately 75 percent higher during high flow releases than during periods of low flow, overshadowing variations in nutrient concentrations caused by seasonality at the Wallisville site.</p><p>Results from the study indicate nutrient delivery to Galveston Bay from the main channel of the Trinity River is likely controlled primarily by high-flow releases from Lake Livingston. For most samples collected at the Wallisville site, organic nitrogen was the predominant form of nitrogen; however, when discharge increased because of releases from Lake Livingston, the percentage of organic nitrogen typically decreased and the percentage of nitrate increased. The concentrations of total phosphorus also increased during high-flow events, likely as a result of suspended sediment within Lake Livingston releases and mobilization of sediment particles in the river channel and flood plain during these periods of high flow. The predominant source of phosphorous to Galveston Bay from the Trinity River is in particulate form closely tied to suspended-sediment concentrations. The changes in nutrient concentration and composition caused by releases from Lake Livingston during this study indicate the reservoir may play an important role in the delivery of nutrients into Galveston Bay. Further study is required to better understand the processes in Lake Livingston influencing the characteristics of nutrient and sediment inflow to Galveston Bay. With phosphorous concentrations correlated to suspended-sediment concentra­tions (coefficient of determination value of 0.75) and with the concentrations of nutrients changing as the discharge changes, the diversion of water and suspended sediment into surround­ing wetlands and channels outside of the main channel of the Trinity River may play a large role in regulating nutrient inputs into Galveston Bay.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20165177","isbn":"978-1-4113-4107-4","collaboration":"Prepared in cooperation with the Texas Water Development Board and the Galveston Bay Estuary Program ","usgsCitation":"Lucena, Zulimar, and Lee, M.T., 2017, Characterization of streamflow, suspended sediment, and nutrients  entering Galveston Bay from the Trinity River, Texas, May 2014–December 2015: U.S. Geological Survey Scientific Investigations Report 2016–5177, 38 p., https://doi.org/10.3133/sir20165177.\n","productDescription":"vii, 37 p.","numberOfPages":"49","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-077707","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":335588,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2016/5177/sir20165177.pdf","text":"Report","size":"11.8 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2016-5177"},{"id":335587,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/sir/2016/5177/coverthb.jpg"}],"country":"United States","state":"Texas","otherGeospatial":"Galveston Bay, Trinity River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.15533447265625,\n              29.7596087873038\n            ],\n            [\n              -94.58953857421875,\n              29.7596087873038\n            ],\n            [\n              -94.58953857421875,\n              30.982318643027536\n            ],\n            [\n              -95.15533447265625,\n              30.982318643027536\n            ],\n            [\n              -95.15533447265625,\n              29.7596087873038\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"mailto:dc_tx@usgs.gov\" data-mce-href=\"mailto:dc_tx@usgs.gov\">Director</a> Texas Water Science Center<br> U.S. Geological Survey<br> 1505 Ferguson Lane<br> Austin, X 78754<br> <a href=\"https://tx.usgs.gov/\" data-mce-href=\"https://tx.usgs.gov/\">https://tx.usgs.gov/</a></p>","tableOfContents":"<ul><li>Abstract&nbsp;</li><li>Introduction</li><li>Methods</li><li>Streamflow Characterization in the Lower Trinity River Watershed</li><li>Suspended-Sediment Concentrations and Loads&nbsp;</li><li>Characterization of Water-Quality Conditions</li><li>Summary&nbsp;</li><li>References Cited</li><li>Appendix 1.

The other rivers also had decreasing flow-normalized trends in nutrient concentrations and loads, except for the Pawtuxet River, which had an increasing trend in nitrite plus nitrate. Increasing trends in flow-normalized chloride concentrations and loads were observed during the study period at all of the rivers, with increases of more than 200 percent in the Blackstone River.</p><p>Small increasing trends in annual mean daily streamflow were observed in 3 of the 4 rivers, with increases of 1.2 to 11 percent; however, the trends were not significant.

To form expected responses to restoration actions, I estimated habitat relationships and trends (2002–2015) for four pond-breeding amphibians on a wildlife refuge (Montana, USA) where changes to restore historical hydrology to the system greatly expanded (≥8 times) the flooded area of the primary breeding site for western toads (</span><i class=\"EmphasisTypeItalic \">Anaxyrus boreas</i><span>).

Multi-season occupancy models based on data from 15 ponds sampled during 7&nbsp;years revealed that the number of breeding subpopulations increased modestly for Columbia spotted frogs (</span><i class=\"EmphasisTypeItalic \">Rana luteiventris</i><span>) and was stationary for long-toed salamanders (</span><i class=\"EmphasisTypeItalic \">Ambystoma macrodactylum</i><span>) and Pacific treefrogs (</span><i class=\"EmphasisTypeItalic \">Pseudacris regilla</i><span>). For these three species, pond depth was the characteristic that was associated most frequently with occupancy or changes in colonization and extinction. In contrast, a large decrease in colonization by western toads explained the decline from eight occupied ponds in 2002 to two ponds in 2015. This decline occurred despite an increase in wetland area and the colonization of a newly created pond. These changes highlight the challenges of managing for multiple species and how management responses can be unpredictable, possibly reducing the efficacy of targeted actions.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10750-016-2979-0","usgsCitation":"Hossack, B.R., 2017, Amphibian dynamics in constructed ponds on a wildlife refuge: developing expected responses to hydrological restoration: Hydrobiologia, v. 790, no. 1, p. 23-33, https://doi.org/10.1007/s10750-016-2979-0.","productDescription":"11 p.","startPage":"23","endPage":"33","ipdsId":"IP-070337","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":335893,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"790","issue":"1","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2016-09-09","publicationStatus":"PW","scienceBaseUri":"58ad5fc1e4b01ccd54f8b517","chorus":{"doi":"10.1007/s10750-016-2979-0","url":"http://dx.doi.org/10.1007/s10750-016-2979-0","publisher":"Springer Nature","authors":"Hossack Blake R.","journalName":"Hydrobiologia","publicationDate":"9/9/2016","auditedOn":"2/15/2017","publiclyAccessibleDate":"9/9/2016"},"contributors":{"authors":[{"text":"Hossack, Blake R. 0000-0001-7456-9564 blake_hossack@usgs.gov","orcid":"https://orcid.org/0000-0001-7456-9564","contributorId":1177,"corporation":false,"usgs":true,"family":"Hossack","given":"Blake","email":"blake_hossack@usgs.gov","middleInitial":"R.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":652472,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We documented a decline in one of the few remaining populations of Southwestern Willow Flycatcher (</span><i><i>Empidonax traillii</i> extimus</i><span>) in southern California, USA, which dropped from 40 to 5 adults between 2000 and 2015. Declines were unequal between sexes (94% for males, 82% for females). Adult sex ratios were female-biased in 10 of 16 yr. The proportion of paired males that were polygynous ranged from 0% to 100%, depending on the ratio of females to males in the adult population. Some males paired with up to 5 females simultaneously. We investigated the role of nestling sex ratio in the female-biased adult sex ratio by using genetic techniques to determine sex from blood samples collected from 162 nestlings in 72 nests from 2002 to 2009. Both population-level and within-brood nestling sex ratios were female-biased, and were not influenced by nest order (first or subsequent), parental mating type (monogamous or polygynous), or year. Disproportionately more females than males were recruited into the breeding population, mirroring nestling and fledgling sex ratios. It thus appears that a skewed nestling sex ratio has contributed to a female-biased adult population, which in turn has influenced mating behavior. We propose that the capacity for polygyny, which generally occurs at low levels in Southwestern Willow Flycatchers, has allowed this population to persist through a decline that might otherwise have resulted in extinction.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1650/CONDOR-16-119.1","usgsCitation":"Kus, B., Howell, S.L., and Wood, D.A., 2017, Female-biased sex ratio, polygyny, and persistence in the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus): The Condor, v. 119, no. 1, p. 17-25, https://doi.org/10.1650/CONDOR-16-119.1.","productDescription":"9 p.","startPage":"17","endPage":"25","ipdsId":"IP-080488","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":470060,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1650/condor-16-119.1","text":"Publisher Index Page"},{"id":335899,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"119","issue":"1","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58ad5fbfe4b01ccd54f8b50b","contributors":{"authors":[{"text":"Kus, Barbara E. 0000-0002-3679-3044 barbara_kus@usgs.gov","orcid":"https://orcid.org/0000-0002-3679-3044","contributorId":3026,"corporation":false,"usgs":true,"family":"Kus","given":"Barbara E.","email":"barbara_kus@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":670071,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Howell, Scarlett L. 0000-0001-7538-4860 showell@usgs.gov","orcid":"https://orcid.org/0000-0001-7538-4860","contributorId":140441,"corporation":false,"usgs":true,"family":"Howell","given":"Scarlett","email":"showell@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":670072,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wood, Dustin A. 0000-0002-7668-9911 dawood@usgs.gov","orcid":"https://orcid.org/0000-0002-7668-9911","contributorId":4179,"corporation":false,"usgs":true,"family":"Wood","given":"Dustin","email":"dawood@usgs.gov","middleInitial":"A.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":670073,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Laboratory experiments suggest that fire-resistant building construction and design could be important for reducing structure destruction, but these need to be evaluated under real wildfire conditions, especially relative to other factors. Using empirical data from destroyed and surviving structures from large wildfires in southern California, we evaluated the relative importance of building construction and structure age compared to other local and landscape-scale variables associated with structure survival. The local-scale analysis showed that window preparation was especially important but, in general, creating defensible space adjacent to the home was as important as building construction. At the landscape scale, structure density and structure age were the two most important factors affecting structure survival, but there was a significant interaction between them. That is, young structure age was most important in higher-density areas where structure survival overall was more likely. On the other hand, newer-construction structures were less likely to survive wildfires at lower density. Here, appropriate defensible space near the structure and accessibility to major roads were important factors. In conclusion, community safety is a multivariate problem that will require a comprehensive solution involving land use planning, fire-safe construction, and property maintenance.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.ijdrr.2016.11.011","usgsCitation":"Syphard, A.D., Brennan, T.J., and Keeley, J.E., 2017, The importance of building construction materials relative to other factors affecting structure survival during wildfire: International Journal of Disaster Risk Reduction, v. 21, p. 140-147, https://doi.org/10.1016/j.ijdrr.2016.11.011.","productDescription":"8 p.","startPage":"140","endPage":"147","ipdsId":"IP-075859","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":335862,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58ad5fc0e4b01ccd54f8b515","contributors":{"authors":[{"text":"Syphard, Alexandra D.","contributorId":8977,"corporation":false,"usgs":false,"family":"Syphard","given":"Alexandra","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":669965,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brennan, Teresa J. 0000-0002-0646-3298 tjbrennan@usgs.gov","orcid":"https://orcid.org/0000-0002-0646-3298","contributorId":4323,"corporation":false,"usgs":true,"family":"Brennan","given":"Teresa","email":"tjbrennan@usgs.gov","middleInitial":"J.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":669966,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Keeley, Jon E. 0000-0002-4564-6521 jon_keeley@usgs.gov","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":1268,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","email":"jon_keeley@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":669964,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Biologists and resource managers designing and conducting monitoring programs for fish in large river systems tend to focus on single river basins or segments of large rivers, missing opportunities to learn from those conducting fish monitoring in other rivers. We briefly examine five long-term fish monitoring programs in large rivers in the United States (Colorado, Columbia, Mississippi, Illinois, and Tallapoosa rivers) and identify opportunities for learning across programs by detailing best monitoring practices and why these practices were chosen. Although monitoring objectives, methods, and program maturity differ between each river system, examples from these five case studies illustrate the important role that long-term monitoring programs play in interpreting temporal and spatial shifts in fish populations for both established objectives and newly emerging questions. We suggest that deliberate efforts to develop a broader collaborative network through benchmarking will facilitate sharing of ideas and development of more effective monitoring

Here we describe structures interpreted to be pipes formed by vertical movement of fluidized sediment. Like many pipes on Earth, those in Gale crater are more resistant to erosion than the host rock; they form near other pipes, dikes, or deformed sediment; and some contain internal concentric or eccentric layering. These structures provide new evidence of the importance of subsurface aqueous processes in shaping the near-surface geology of Mars.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/G38339.1","usgsCitation":"Rubin, D.M., Fairen, A., Frydenvang, J., Gasnault, O., Gelfenbaum, G.R., Goetz, W., Grotzinger, J., Le Mouélic, S., Mangold, N., Newsom, H., Oehler, D.Z., Rapin, W., Schieber, J., and Wiens, R.C., 2017, Fluidized-sediment pipes in Gale crater, Mars, and possible Earth analogs: Geology, v. 45, no. 1, p. 7-10, https://doi.org/10.1130/G38339.1.","productDescription":"4 p.","startPage":"7","endPage":"10","ipdsId":"IP-071597","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":470061,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1130/g38339.1","text":"External Repository"},{"id":335900,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"1","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2017-01-01","publicationStatus":"PW","scienceBaseUri":"58ad5fc0e4b01ccd54f8b50d","contributors":{"authors":[{"text":"Rubin, David M. 0000-0003-1169-1452 drubin@usgs.gov","orcid":"https://orcid.org/0000-0003-1169-1452","contributorId":3159,"corporation":false,"usgs":true,"family":"Rubin","given":"David","email":"drubin@usgs.gov","middleInitial":"M.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":670053,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fairen, A.G.","contributorId":25335,"corporation":false,"usgs":true,"family":"Fairen","given":"A.G.","email":"","affiliations":[],"preferred":false,"id":670054,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Frydenvang, J.","contributorId":181927,"corporation":false,"usgs":false,"family":"Frydenvang","given":"J.","affiliations":[],"preferred":false,"id":670055,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gasnault, Olivier","contributorId":181928,"corporation":false,"usgs":false,"family":"Gasnault","given":"Olivier","affiliations":[],"preferred":false,"id":670056,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Gelfenbaum, Guy R. 0000-0003-1291-6107 ggelfenbaum@usgs.gov","orcid":"https://orcid.org/0000-0003-1291-6107","contributorId":742,"corporation":false,"usgs":true,"family":"Gelfenbaum","given":"Guy","email":"ggelfenbaum@usgs.gov","middleInitial":"R.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":670052,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Goetz, W.","contributorId":181929,"corporation":false,"usgs":false,"family":"Goetz","given":"W.","email":"","affiliations":[],"preferred":false,"id":670057,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Grotzinger, J.P.","contributorId":181930,"corporation":false,"usgs":false,"family":"Grotzinger","given":"J.P.","affiliations":[],"preferred":false,"id":670058,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Le Mouélic, S.","contributorId":77819,"corporation":false,"usgs":true,"family":"Le Mouélic","given":"S.","affiliations":[],"preferred":false,"id":670083,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Mangold, N.","contributorId":101164,"corporation":false,"usgs":true,"family":"Mangold","given":"N.","email":"","affiliations":[],"preferred":false,"id":670084,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Newsom, H.","contributorId":98934,"corporation":false,"usgs":true,"family":"Newsom","given":"H.","email":"","affiliations":[],"preferred":false,"id":670085,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Oehler, D.

However, our ability to do so is of utmost importance to predict the effects of climate change on species distributions. We examined how populations of three species of wetland-breeding amphibians, which varied in life history requirements, responded to a six-year period of extremely variable precipitation. This interval was punctuated by both extensive drought and heavy precipitation and flooding, providing a natural experiment to measure community responses to environmental perturbations. We estimated occurrence dynamics using a discrete hidden Markov modeling approach that incorporated information regarding habitat state and predator–prey interactions. This approach allowed us to measure how metapopulation dynamics of each amphibian species was affected by interactions among weather, wetland hydroperiod, and co-occurrence with fish predators. The pig frog, a generalist, proved most resistant to perturbations, with both colonization and persistence being unaffected by seasonal variation in precipitation or co-occurrence with fishes. The ornate chorus frog, an ephemeral wetland specialist, responded positively to periods of drought owing to increased persistence and colonization rates during periods of low-rainfall. Low probabilities of occurrence of the ornate chorus frog in long-duration wetlands were driven by interactions with predators due to low colonization rates when fishes were present. The mole salamander was most sensitive to shifts in water availability. In our study area, this species never occurred in short-duration wetlands and persistence probabilities decreased during periods of drought. At the same time, negative effects occurred with extreme precipitation because flooding facilitated colonization of fishes to isolated wetlands and mole salamanders did not colonize wetlands once fishes were present. We demonstrate that the effects of changes in water availability depend on interactions with predators and wetland type and are influenced by the life history of each of our species. The dynamic species occurrence modeling approach we used offers promise for other systems when the goal is to disentangle the complex interactions that determine species responses to environmental variability.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1002/eap.1442","usgsCitation":"Davis, C.L., Miller, D.A., Walls, S.C., Barichivich, W.J., Riley, J.W., and Brown, M.E., 2017, Species interactions and the effects of climate variability on a wetland amphibian metacommunity: Ecological Applications, v. 27, no. 1, p. 285-296, https://doi.org/10.1002/eap.1442.","productDescription":"12 p.","startPage":"285","endPage":"296","ipdsId":"IP-070788","costCenters":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"links":[{"id":335901,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"St. Marks National Wildlife Refuge","volume":"27","issue":"1","publishingServiceCenter":{"id":5,"text":"Lafayette PSC"},"noUsgsAuthors":false,"publicationDate":"2017-01-04","publicationStatus":"PW","scienceBaseUri":"58ad5fc0e4b01ccd54f8b50f","contributors":{"authors":[{"text":"Davis, Courtney L.","contributorId":181922,"corporation":false,"usgs":false,"family":"Davis","given":"Courtney","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":670047,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, David A.W. davidmiller@usgs.gov","contributorId":4043,"corporation":false,"usgs":true,"family":"Miller","given":"David","email":"davidmiller@usgs.gov","middleInitial":"A.W.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":7260,"text":"Pennsylvania State University","active":true,"usgs":false}],"preferred":false,"id":670048,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Walls, Susan C. 0000-0001-7391-9155 swalls@usgs.gov","orcid":"https://orcid.org/0000-0001-7391-9155","contributorId":2310,"corporation":false,"usgs":true,"family":"Walls","given":"Susan","email":"swalls@usgs.gov","middleInitial":"C.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":false,"id":670046,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Barichivich, William J. 0000-0003-1103-6861 wbarichivich@usgs.gov","orcid":"https://orcid.org/0000-0003-1103-6861","contributorId":3697,"corporation":false,"usgs":true,"family":"Barichivich","given":"William","email":"wbarichivich@usgs.gov","middleInitial":"J.","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":true,"id":670049,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Riley, Jeffrey W. 0000-0001-5525-3134 jriley@usgs.gov","orcid":"https://orcid.org/0000-0001-5525-3134","contributorId":3605,"corporation":false,"usgs":true,"family":"Riley","given":"Jeffrey","email":"jriley@usgs.gov","middleInitial":"W.","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true},{"id":316,"text":"Georgia Water Science Center","active":true,"usgs":true}],"preferred":true,"id":670050,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Brown, Mary E. 0000-0002-5580-137X","orcid":"https://orcid.org/0000-0002-5580-137X","contributorId":181924,"corporation":false,"usgs":true,"family":"Brown","given":"Mary","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":670051,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

However, characterizing landslide-wide kinematics is rare, especially at broadly ranging timescales. We used highly detailed kinematic data obtained using photogrammetry and field mapping during the 1980s and 1990s and our 4.3-day ground-based InSAR survey during 2010 to study kinematics of the large, persistently moving Slumgullion landslide. The landslide was segregated into 11 kinematic elements using the 1980s–1990s data and the InSAR survey revealed most of these elements within a few hours. Averages of InSAR-derived displacement point measures within each element agreed well with higher quality in situ observations; averaging was deemed necessary because adverse look angles for the radar coupled with tree cover on the landslide introduced error in the InSAR results. We found that the landslide moved during 2010 at about half its 1985–1990 speed, but slowing was most pronounced at the landslide head. Gradually decreased precipitation and increased temperature between the periods likely resulted in lower groundwater levels and consequent slowing of the landslide. We used GPS survey results and limit-equilibrium modeling to analyze changing stability of the landslide head from observed thinning and found that its stability increased between the two periods, which would result in its slowing, and the consequent slowing of the entire landslide. Additionally, InSAR results suggested movement of kinematic element boundaries in the head region and our field mapping verified that they moved and changed character, likely because of the long-term increasing head stability. On an hourly basis, InSAR results were near error bounds but suggested landslide acceleration in response to seemingly negligible rainfall. Pore-pressure diffusion modeling suggested that rainfall infiltration affected frictional strength only to shallow depths along the landslide's marginal faults, highlighting their importance in controlling landslide stability. Hourly results also suggested that motion propagated along the 3.9-km length of the active landslide, even following sub-millimeter displacements, while strengthening of landslide shear boundaries during faster movement was likely critical in regulating the landslide's motion. Hence, detailed kinematic characterizations obtained from traditional and emerging approaches helped to reveal that mechanisms controlling landslide movement and evolution over decades also are critical to sub-millimeter movement on a nearly continuous basis.</p>","language":"English","doi":"10.1016/j.geomorph.2017.02.011","usgsCitation":"Schulz, W.H., Coe, J.A., Ricci, P., Smoczyk, G.M., Shurtleff, B.L., and Panosky, J., 2017, Landslide kinematics and their potential controls from hourly to decadal timescales: Insights from integrating ground-based InSAR measurements with structural maps and long-term monitoring data: Geomorphology, v. 285, p. 121-136, https://doi.org/10.1016/j.geomorph.2017.02.011.","productDescription":"16 p.

The virus grew optimally in the CHSE-214 cell line at 15°C producing a diffuse cytopathic effect; however, juvenile rainbow trout exposed to cell culture-grown virus showed no mortality or gross pathology. Electron microscopy of preparations from infected cell cultures revealed the presence of typical orthomyxovirus particles. The complete genome of RbtOV is comprised of eight linear segments of single-stranded, negative-sense RNA having highly conserved 5′ and 3′-terminal nucleotide sequences. Another virus isolated in 2014 from steelhead trout (also </span><i>O. mykiss</i><span>) in Wisconsin, USA, and designated SttOV was found to have eight genome segments with high amino acid sequence identities (89–99%) to the corresponding genes of RbtOV, suggesting these new viruses are isolates of the same virus species and may be more widespread than currently realized. The new isolates had the same genome segment order and the closest pairwise amino acid sequence identities of 16–42% with </span><i>Infectious salmon anemia virus</i><span> (ISAV), the type species and currently only member of the genus </span><i>Isavirus</i><span> in the family </span><i>Orthomyxoviridae</i><span>. However, pairwise comparisons of the predicted amino acid sequences of the 10 RbtOV and SttOV proteins with orthologs from representatives of the established orthomyxoviral genera and a phylogenetic analysis using the PB1 protein showed that while RbtOV and SttOV clustered most closely with ISAV, they diverged sufficiently to merit consideration as representatives of a novel genus. A set of PCR primers was designed using conserved regions of the PB1 gene to produce amplicons that may be sequenced for identification of similar fish orthomyxoviruses in the future.</span></p>","language":"English","publisher":"Elsevier B.V.","doi":"10.1016/j.virusres.2017.01.005","usgsCitation":"Batts, W.N., LaPatra, S.E., Katona, R., Leis, E., Fei Fan Ng, T., Bruieuc, M.S., Breyta, R., Purcell, M.K., Waltzek, T., Delwart, E., and Winton, J., 2017, Molecular characterization of a novel orthomyxovirus from rainbow and steelhead trout (<i>Oncorhynchus mykiss</i>): Virus Research, v. 230, p. 38-49, https://doi.org/10.1016/j.virusres.2017.01.005.","productDescription":"11 p.","startPage":"38","endPage":"49","ipdsId":"IP-080255","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":470062,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1016/j.virusres.2017.01.005","text":"External Repository"},{"id":335168,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"230","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c4e8d0e4b0f37a93ee9c18","contributors":{"authors":[{"text":"Batts, William N. 0000-0002-6469-9004 bbatts@usgs.gov","orcid":"https://orcid.org/0000-0002-6469-9004","contributorId":3815,"corporation":false,"usgs":true,"family":"Batts","given":"William","email":"bbatts@usgs.gov","middleInitial":"N.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":663306,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"LaPatra, Scott E.","contributorId":179323,"corporation":false,"usgs":false,"family":"LaPatra","given":"Scott","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":663307,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Katona, Ryan","contributorId":179324,"corporation":false,"usgs":false,"family":"Katona","given":"Ryan","email":"","affiliations":[],"preferred":false,"id":663308,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Leis, Eric","contributorId":179325,"corporation":false,"usgs":false,"family":"Leis","given":"Eric","affiliations":[],"preferred":false,"id":663309,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fei Fan Ng, Terry","contributorId":179326,"corporation":false,"usgs":false,"family":"Fei Fan Ng","given":"Terry","email":"","affiliations":[],"preferred":false,"id":663310,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bruieuc, Marine S.O.","contributorId":179327,"corporation":false,"usgs":false,"family":"Bruieuc","given":"Marine","email":"","middleInitial":"S.O.","affiliations":[],"preferred":false,"id":663311,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Breyta, Rachel","contributorId":150355,"corporation":false,"usgs":false,"family":"Breyta","given":"Rachel","affiliations":[],"preferred":false,"id":663312,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Purcell, Maureen K. 0000-0003-0154-8433 mpurcell@usgs.gov","orcid":"https://orcid.org/0000-0003-0154-8433","contributorId":168475,"corporation":false,"usgs":true,"family":"Purcell","given":"Maureen","email":"mpurcell@usgs.gov","middleInitial":"K.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":663313,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Waltzek, Thomas B.","contributorId":9574,"corporation":false,"usgs":true,"family":"Waltzek","given":"Thomas B.","affiliations":[],"preferred":false,"id":663314,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Delwart, Eric","contributorId":179329,"corporation":false,"usgs":false,"family":"Delwart","given":"Eric","email":"","affiliations":[],"preferred":false,"id":663315,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Winton, James 0000-0002-3505-5509 jwinton@usgs.gov","orcid":"https://orcid.org/0000-0002-3505-5509","contributorId":179330,"corporation":false,"usgs":true,"family":"Winton","given":"James","email":"jwinton@usgs.gov","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":663316,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

The North American Great Plains exemplify such intraplate earthquake localization, with both natural and induced seismicity generally clustered in discrete zones. Here we use seismic velocity, gravity and topography to generate a 3D lithospheric density model of the region; subsequent finite-element modelling shows that seismicity focuses in regions of high-gravity-derived deviatoric stress. Furthermore, predicted principal stress directions generally align with those observed independently in earthquake moment tensors and borehole breakouts. Body forces therefore appear to control the state of stress and thus the location and style of intraplate earthquakes in the central United States with no influence from mantle convection or crustal weakness necessary. These results show that mapping where gravitational body forces encourage seismicity is crucial to understanding and appraising intraplate seismic hazard.</span></p>","language":"English","publisher":"Nature Publishing Group","doi":"10.1038/ncomms14314","usgsCitation":"Levandowski, W.B., Zellman, M., and Briggs, R.W., 2017, Gravitational body forces focus North American intraplate earthquakes: Nature Communications, v. 8, Article 14314: 9 p., https://doi.org/10.1038/ncomms14314.","productDescription":"Article 14314: 9 p.","ipdsId":"IP-073321","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":470063,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1038/ncomms14314","text":"Publisher Index Page"},{"id":342259,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.5,\n              45.5\n            ],\n            [\n              -94.5,\n              45.5\n            ],\n            [\n              -94.5,\n              36.5\n            ],\n            [\n              -105.5,\n              36.5\n            ],\n            [\n              -105.5,\n              45.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"8","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2017-02-17","publicationStatus":"PW","scienceBaseUri":"593910ace4b0764e6c5e8852","contributors":{"authors":[{"text":"Levandowski, William Brower 0000-0003-4903-5012 wlevandowski@usgs.gov","orcid":"https://orcid.org/0000-0003-4903-5012","contributorId":5729,"corporation":false,"usgs":true,"family":"Levandowski","given":"William","email":"wlevandowski@usgs.gov","middleInitial":"Brower","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":697456,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zellman, Mark","contributorId":167020,"corporation":false,"usgs":false,"family":"Zellman","given":"Mark","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":697457,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Briggs, Richard W. 0000-0001-8108-0046 rbriggs@usgs.gov","orcid":"https://orcid.org/0000-0001-8108-0046","contributorId":139002,"corporation":false,"usgs":true,"family":"Briggs","given":"Richard","email":"rbriggs@usgs.gov","middleInitial":"W.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":697458,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
