However, the effects of non-Fe-containing minerals on iron dissolution remain unknown. This work describes metal-metal synergistic and antagonistic effects on iron dissolution that go beyond aggregation and ionic strength effects in mineral dust mixtures. In this study, we investigated iron mobilization by proton-promoted dissolution in natural mineral dust samples from the Kalahari Desert (SZ1) and Australian Red Dawn event (RO), along with one iron oxide proxy, hematite. The total iron dissolution in natural dust samples highly corresponds with the respective amount of Ti, rather than their particle sizes or Fe contents. The dust sample with high Ti content, SZ1, also showed a higher fraction of dissolved Fe(II), under dark conditions. These observations are in good agreement with the dissolution data for hematite artificially mixed with metal oxides. Total iron dissolution in hematite, mixed with TiO<sub>2</sub>, is 1.5- and 2-fold higher compared to that of just hematite under dark and light conditions, respectively. However, dissolution of hematite is suppressed when mixed with Al<sub>2</sub>O<sub>3</sub> and CaO. Under dark conditions, furthermore, dissolved Fe(II) fraction is enhanced for hematite when mixed with TiO<sub>2</sub> compared to that of other mixtures or hematite alone. Yet, dissolved Fe(II) is lower in hematite mixed with TiO<sub>2</sub> under light conditions compared to that of hematite alone, suggesting photo-oxidation of Fe(II) by reactive oxygen species, such as OH radicals.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.atmosenv.2018.06.010","usgsCitation":"Hettiarachchi, E., Reynolds, R.L., Goldstein, H.L., Moskowitz, B.M., and Rubasinghege, G., 2018, Iron dissolution and speciation in atmospheric mineral dust: Metal-metal synergistic and antagonistic effects: Atmospheric Environment, v. 187, p. 417-423, https://doi.org/10.1016/j.atmosenv.2018.06.010.","productDescription":"7 p.","startPage":"417","endPage":"423","ipdsId":"IP-094579","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":468303,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.atmosenv.2018.06.010","text":"Publisher Index Page"},{"id":358586,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"187","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c10a91ae4b034bf6a7e4fba","contributors":{"authors":[{"text":"Hettiarachchi, Eshani","contributorId":209918,"corporation":false,"usgs":false,"family":"Hettiarachchi","given":"Eshani","email":"","affiliations":[{"id":34868,"text":"New Mexico Institute of Mining and Technology","active":true,"usgs":false}],"preferred":false,"id":749094,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":147880,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true},{"id":271,"text":"Federal Center","active":false,"usgs":true}],"preferred":true,"id":749096,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goldstein, Harland L. 0000-0002-6092-8818 hgoldstein@usgs.gov","orcid":"https://orcid.org/0000-0002-6092-8818","contributorId":147881,"corporation":false,"usgs":true,"family":"Goldstein","given":"Harland","email":"hgoldstein@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":false,"id":749093,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moskowitz, Bruce M.","contributorId":189164,"corporation":false,"usgs":false,"family":"Moskowitz","given":"Bruce","email":"","middleInitial":"M.","affiliations":[{"id":17684,"text":"University of Minnesota, Minneapolis, MN","active":true,"usgs":false}],"preferred":false,"id":749097,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Rubasinghege, Gayan","contributorId":209919,"corporation":false,"usgs":false,"family":"Rubasinghege","given":"Gayan","email":"","affiliations":[{"id":34868,"text":"New Mexico Institute of Mining and Technology","active":true,"usgs":false}],"preferred":false,"id":749095,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

One reason for this [among many (</span><i>3</i><span>)] is a shortfall in funding, raising a conundrum for agencies responsible for species recovery: Should resources be allocated toward species facing imminent extinction or species whose long-term survival can most benefit from investment? Some argue that the latter strategy is ethically unsound because it may abandon species with little hope of long-term recovery [for example, (</span><i>4</i><span>)], even when science suggests that the former strategy may miss opportunities to prevent species from ever experiencing the risk of imminent extinction (</span><i>2</i><span>).

Obvious examples include predator control and nest parasite reduction. Less obvious is the control of blood-feeding arthropods. We present a case study on the effect of blood-feeding black flies (Simulium spp.) on reintroduced Whooping Cranes (Grus americana). Our intent is to provide a transferrable, science-driven approach for determining the effects of blood-feeding arthropods on endangered vertebrates, and demonstrate an approach for guiding selection of management actions for managers faced with competing objectives. A multi-year experiment demonstrated that black flies reduce nest success in reintroduced cranes by driving the birds off their nests during incubation. Deciding how to respond, however, is complicated because the target black flies are native species that serve important ecological functions. We suggest that a decision-analytic approach can inspire the development of creative management alternatives and facilitate a transparent process that evaluates trade-offs among competing objectives. Recognizing that these decisions involve trade-offs, which must be weighed in the context of each case, is crucial to identifying alternatives that best balance multiple management objectives. Given the uncertainty about the population dynamics of blood-feeding arthropods, an adaptive management approach will offer substantial benefits. ","language":"English","publisher":"The Society for Conservation Biology","doi":"10.1111/cobi.13262","usgsCitation":"Adler, P.H., Barzen, J.A., Gray, E., Lacy, A.E., Urbanek, R.P., and Converse, S.J., 2018, The dilemma of pest suppression in the conservation of endangered species: Conservation Biology, v. 33, no. 4, p. 788-796, https://doi.org/10.1111/cobi.13262.","productDescription":"9 p.","startPage":"788","endPage":"796","ipdsId":"IP-101284","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":379519,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.47216796875,\n              43.13306116240612\n            ],\n            [\n              -88.96728515624999,\n              43.13306116240612\n            ],\n            [\n              -88.96728515624999,\n              44.213709909702054\n            ],\n            [\n              -91.47216796875,\n              44.213709909702054\n            ],\n            [\n              -91.47216796875,\n              43.13306116240612\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"33","issue":"4","noUsgsAuthors":false,"publicationDate":"2019-02-25","publicationStatus":"PW","contributors":{"editors":[{"text":"Urbanek, Richard P.","contributorId":243332,"corporation":false,"usgs":false,"family":"Urbanek","given":"Richard","email":"","middleInitial":"P.","affiliations":[{"id":37461,"text":"fws","active":true,"usgs":false}],"preferred":false,"id":802073,"contributorType":{"id":2,"text":"Editors"},"rank":5}],"authors":[{"text":"Adler, Peter H.","contributorId":243330,"corporation":false,"usgs":false,"family":"Adler","given":"Peter","email":"","middleInitial":"H.","affiliations":[{"id":48690,"text":"clemson","active":true,"usgs":false}],"preferred":false,"id":802068,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barzen, Jeb A.","contributorId":190797,"corporation":false,"usgs":false,"family":"Barzen","given":"Jeb","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":802069,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gray, Elmer","contributorId":243331,"corporation":false,"usgs":false,"family":"Gray","given":"Elmer","affiliations":[{"id":24699,"text":"UGA","active":true,"usgs":false}],"preferred":false,"id":802070,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lacy, Anne E","contributorId":174362,"corporation":false,"usgs":false,"family":"Lacy","given":"Anne","email":"","middleInitial":"E","affiliations":[{"id":16606,"text":"International Crane Foundation","active":true,"usgs":false}],"preferred":false,"id":802071,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Urbanek, Richard P.","contributorId":38400,"corporation":false,"usgs":true,"family":"Urbanek","given":"Richard","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":802200,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Converse, Sarah J. 0000-0002-3719-5441 sconverse@usgs.gov","orcid":"https://orcid.org/0000-0002-3719-5441","contributorId":173772,"corporation":false,"usgs":true,"family":"Converse","given":"Sarah","email":"sconverse@usgs.gov","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":802072,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

However, a major concern of mail surveys have long been relatively low response rates compared to telephone or face-to-face interviews. Survey research has largely focused on achieving high response rates; however, in some situations even well designed surveys can have low response rates. We present an example of a 3-page (25 questions) survey measuring opinions and attitudes about native fish management in the South Dakota Black Hills region that received a relatively low response rate (21%) using a mailing, postcard, and second mailing of the questionnaire. We compare response rate and data quality of a third mailing of the full questionnaire with a one-page (5 questions) questionnaire measuring key variables to evaluate possible nonresponse bias. Within the total survey error (TSE) paradigm we provide evidence that reliable and useful information was collected by this survey.","language":"English","publisher":"Taylor & Francis","doi":"10.1080/10871209.2018.1523508","usgsCitation":"Gigliotti, L.M., and Fompa, S., 2018, Low survey response!

Using a stratified random survey design, we allocated sample plots by elevation and land cover with a preference for wetland cover types used by shorebirds, a group of particular interest to land managers. We surveyed birds during 10-min counts at 792 points across 52, 5 km × 5 km sample plots distributed from south of the Naknek River (58.70°N,157.00°W) to north of Port Moller (56.00°N,160.52°W). We detected 95 bird species including 19 species of shorebirds and 34 species (36% of total) considered at the time to be of conservation concern for the land managers in the region. The most numerous shorebirds on point counts were dunlin&nbsp;</span><i>Calidris alpina,</i><span>&nbsp;short-billed dowitcher&nbsp;</span><i>Limnodromus griseus,</i><span>&nbsp;and Wilson's snipe&nbsp;</span><i>Gallinago delicata.</i><span>We found the breeding-season endemic marbled godwit&nbsp;</span><i>Limosa fedoa beringiae</i><span>&nbsp;at 20 plots within a 3,000-km</span><sup>2</sup><span>&nbsp;area from north of Ugashik Bay to just north of Port Heiden and east to the headwaters of the Dog Salmon and Ugashik rivers.

The Williston Basin is one of North America's largest&nbsp;oil production&nbsp;areas and overlaps the&nbsp;Prairie&nbsp;Pothole Region, an area densely populated with&nbsp;wetlands&nbsp;that provide important wildlife habitat. Although historical disposal practices that released chloride-rich waters (brines) produced during&nbsp;oil extraction&nbsp;into the environment are no longer used, brine spills still occur frequently. We sampled 33 wetlands for three amphibian species in Montana and North Dakota during 2015–2017, primarily on National Wildlife Refuges, and used N-mixture models to determine how abundance varied with evidence of brine contamination. To provide insight into effects of historical versus contemporary contamination, we also estimated the association of well density and age with water quality and amphibian abundance. Abundance of boreal chorus&nbsp;frog&nbsp;(</span><i>Pseudacris maculata</i><span>)&nbsp;larvae&nbsp;declined most rapidly in response to increased chloride (range: 0.04–17,500 mg/L), followed by the northern leopard frog (</span><span><i>Lithobates</i></span><span>&nbsp;[</span><i>Rana</i><span>]&nbsp;</span><i>pipiens</i><span>) and barred&nbsp;tiger salamander&nbsp;(</span><i>Ambystoma mavortium</i><span>). Water quality and population- and community-level abundance of amphibians were more strongly related to nearby wells (≤800 m) installed before 1982 than to wells installed since 1982. These results suggest historical brine management practices were the primary driver of contamination and reduced amphibian abundance in wetlands we sampled, reflecting multi-decadal ecological effects. These persistent effects also underscore the critical need for tools to restore landscapes affected by brine contamination.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2018.10.007","usgsCitation":"Hossack, B.R., Smalling, K., Anderson, C.W., Preston, T.M., Cozzarelli, I.M., and Honeycutt, R.K., 2018, Effects of persistent energy-related brine contamination on amphibian abundance in national wildlife refuge wetlands: Biological Conservation, v. 228, p. 36-43, https://doi.org/10.1016/j.biocon.2018.10.007.","productDescription":"8 p.","startPage":"36","endPage":"43","ipdsId":"IP-097267","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":468320,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.biocon.2018.10.007","text":"Publisher Index Page"},{"id":358389,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana, North Dakota, South Dakota","volume":"228","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c10a91ee4b034bf6a7e4ff3","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":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":748561,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smalling, Kelly L. 0000-0002-1214-4920","orcid":"https://orcid.org/0000-0002-1214-4920","contributorId":204696,"corporation":false,"usgs":true,"family":"Smalling","given":"Kelly L.","affiliations":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"preferred":true,"id":748562,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Anderson, Chauncey W. 0000-0002-1016-3781 chauncey@usgs.gov","orcid":"https://orcid.org/0000-0002-1016-3781","contributorId":140160,"corporation":false,"usgs":true,"family":"Anderson","given":"Chauncey","email":"chauncey@usgs.gov","middleInitial":"W.","affiliations":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":748563,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Preston, Todd M. 0000-0002-8812-9233","orcid":"https://orcid.org/0000-0002-8812-9233","contributorId":204676,"corporation":false,"usgs":true,"family":"Preston","given":"Todd","email":"","middleInitial":"M.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":748564,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cozzarelli, Isabelle M. 0000-0002-5123-1007 icozzare@usgs.gov","orcid":"https://orcid.org/0000-0002-5123-1007","contributorId":1693,"corporation":false,"usgs":true,"family":"Cozzarelli","given":"Isabelle","email":"icozzare@usgs.gov","middleInitial":"M.","affiliations":[{"id":49175,"text":"Geology, Energy & Minerals Science Center","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":748565,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Honeycutt, R.

Widespread but now discontinuous patches of a deeply weathered sand and gravel are found west of the Fall Line, capping the highest hilltops. Near the community of Midlothian, Virginia, the gravels are underlain by fine-grained marine silts that bear an informative assemblage of fossil dinoflagellate cysts (dinocysts). In situ dinocysts belong to middleMiocene zone DN7, which is calibrated to ~12-13 Ma. These deposits are assigned to the upper part of the Choptank Formation, which crops out ~ 25 km(15 mi) to the east at an elevation ~ 60m(200 ft) lower. The dinocyst assemblage suggests that the maximum extent of this Choptank transgression probably covered a significant expanse of the Virginia Piedmont. The Choptank marine silts constrain the age of the unconformably overlying Midlothian gravels to younger than the latter part of the middle Miocene. Previous work has indicated that these gravels also are older than the Pliocene Yorktown Formation. Rare, reworked dinocysts in these Choptank outcrops west of the Fall Line are sourced from older deposits of more than one age. The source could be older updip strata of the lower Eocene Nanjemoy Formation, now erosionally removed. Alternatively, the source could be material referable to the upper Eocene Exmore Formation that resulted from the Chesapeake Bay impact event.</span></p>","language":"English","publisher":"Micropaleontology Press","usgsCitation":"Edwards, L.E., Weems, R.E., Carter, M.W., Spears, D., and Powars, D.S., 2018, The significance of dinoflagellates in the Miocene Choptank Formation beneath the Midlothian gravels in the southeastern Virginia Piedmont: Stratigraphy, v. 15, no. 3, p. 179-195.","productDescription":"17 p.","startPage":"179","endPage":"195","ipdsId":"IP-094928","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":358206,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":381744,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.micropress.org/microaccess/stratigraphy/issue-342/article-2076"}],"country":"United States","otherGeospatial":"Miocene Choptank Formation","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -79,\n              36.5\n            ],\n            [\n              -75,\n              36.5\n            ],\n            [\n              -75,\n              39\n            ],\n            [\n              -79,\n              39\n            ],\n            [\n              -79,\n              36.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"15","issue":"3","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5bc02f76e4b0fc368eb53833","contributors":{"authors":[{"text":"Edwards, Lucy E. 0000-0003-4075-3317 leedward@usgs.gov","orcid":"https://orcid.org/0000-0003-4075-3317","contributorId":2647,"corporation":false,"usgs":true,"family":"Edwards","given":"Lucy","email":"leedward@usgs.gov","middleInitial":"E.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":747513,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weems, Robert E. 0000-0002-1907-7804 rweems@usgs.gov","orcid":"https://orcid.org/0000-0002-1907-7804","contributorId":2663,"corporation":false,"usgs":true,"family":"Weems","given":"Robert","email":"rweems@usgs.gov","middleInitial":"E.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":747514,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carter, Mark W. 0000-0003-0460-7638 mcarter@usgs.gov","orcid":"https://orcid.org/0000-0003-0460-7638","contributorId":4808,"corporation":false,"usgs":true,"family":"Carter","given":"Mark","email":"mcarter@usgs.gov","middleInitial":"W.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":747515,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Spears, David 0000-0001-8599-3125","orcid":"https://orcid.org/0000-0001-8599-3125","contributorId":139189,"corporation":false,"usgs":false,"family":"Spears","given":"David","email":"","affiliations":[{"id":12690,"text":"Virginia Department of Mines, Minerals, and Energy, Charlottesville, VA","active":true,"usgs":false}],"preferred":false,"id":747516,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Powars, David S. 0000-0002-6787-8964 dspowars@usgs.gov","orcid":"https://orcid.org/0000-0002-6787-8964","contributorId":1181,"corporation":false,"usgs":true,"family":"Powars","given":"David","email":"dspowars@usgs.gov","middleInitial":"S.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":747517,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The biological mechanisms leading to TDC emergence may vary among systems, but in fishes, one common outcome is high mortality among early life stages. Here, we review the causes and consequences of thiamine deficiency in fishes and identify potential solutions. First, we examine the biochemical and physiological roles of thiamine in vertebrates and find that thiamine deficiency consistently results in impaired neurological function across diverse taxa. Next, we review natural producers of thiamine, which include bacteria, fungi, and plants, and suggest that thiamine is not currently limiting for most animal species inhabiting natural aquatic environments. A survey of historic occurrences of thiamine deficiency identifies consumption of a thiamine-degrading enzyme, thiaminase, as the primary explanation for low levels of thiamine in individuals and subsequent onset of TDC. Lastly, we review conservation and management strategies for TDC mitigation ranging from evolutionary rescue to managing for a diverse forage base. As recent evidence suggests occurrences of thiamine deficiency may be increasing in frequency, increased awareness and a better mechanistic understanding of the underlying causes associated with thiamine deficiency may help prevent further population declines.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s11160-018-9538-x","usgsCitation":"Harder, A.M., Ardren, W.R., Evans, A.N., Futia, M.H., Kraft, C.E., Marsden, J., Richter, C.A., Rinchard, J., Tillitt, D.E., and Christie, M.R., 2018, Thiamine deficiency in fishes: Causes, consequences, and potential solutions: Reviews in Fish Biology and Fisheries, v. 28, no. 4, p. 865-886, https://doi.org/10.1007/s11160-018-9538-x.","productDescription":"12 p.","startPage":"865","endPage":"886","ipdsId":"IP-096509","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":358191,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"4","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationDate":"2018-10-04","publicationStatus":"PW","scienceBaseUri":"5bc02f78e4b0fc368eb53841","contributors":{"editors":[{"text":"Christie, Mark R.","contributorId":191035,"corporation":false,"usgs":false,"family":"Christie","given":"Mark","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":747459,"contributorType":{"id":2,"text":"Editors"},"rank":10}],"authors":[{"text":"Harder, Avril M.","contributorId":208496,"corporation":false,"usgs":false,"family":"Harder","given":"Avril","email":"","middleInitial":"M.","affiliations":[{"id":37808,"text":"Department of Biological Sciences, Purdue University, 915 W.

Examples include processing geospatial data, analyzing -omics data, and running large-scale simulations. Conventional desktop computing cannot handle these tasks when they are large, and high-performance computing is not always available nor the most appropriate solution for all computationally intense problems. High-throughput computing (HTC) is one method for handling computationally intense research. In contrast to high-performance computing, which uses a single \"supercomputer,\" HTC can distribute tasks over many computers (e.g., idle desktop computers, dedicated servers, or cloud-based resources). HTC facilities exist at many academic and government institutes and are relatively easy to create from commodity hardware. Additionally, consortia such as Open Science Grid facilitate HTC, and commercial entities sell cloud-based solutions for researchers who lack HTC at their institution. We provide an introduction to HTC for biologists and environmental scientists.

These events are the first earthquakes in the state exceeding M</span><sub>w</sub><span>5.0 since the 2011 M</span><sub>w</sub><span>5.7 Prague earthquake and likely result from wide-scale deep&nbsp;fluid-injection.

We also include newly reported, calibrated event locations for the Cushing earthquake. We find that the Pawnee earthquake ruptured within the crystalline basement with the shallowest slip occurring at depths of 3.1–4.3 km. We find a similar, though shallower, crystalline basement source for the Cushing earthquake with a minimum depth to slip of 1.6–2.3 km. Despite the smaller magnitude of the Cushing earthquake, it generated anomalously high&nbsp;ground motions&nbsp;and damage compared to the larger Pawnee and Fairview earthquakes. We postulate that the shallow source of the Cushing earthquakes provides one explanation for the higher than expected ground motions. The Fairview earthquake generated no detectable co-seismic displacements, which is consistent with a relatively deep earthquake source (~8.5 km). We do, however, identify a 16 km stretch of&nbsp;floodplain&nbsp;where widespread&nbsp;liquefaction&nbsp;occurred in response to the Fairview earthquake, and where 30&nbsp;gas production&nbsp;wells were exposed to surface displacements exceeding 5 cm. Consequently, the depth to crystalline basement, which limits the depth of injection-induced earthquakes in Oklahoma, and the potential for liquefaction are important factors in assessing shaking risk in the central United States.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.rse.2018.09.005","usgsCitation":"Barnhart, W., Yeck, W.L., and McNamara, D.E., 2018, Induced earthquake and liquefaction hazards in Oklahoma, USA: Constraints from InSAR: Remote Sensing of Environment, v. 218, p. 1-12, https://doi.org/10.1016/j.rse.2018.09.005.","productDescription":"12 p.","startPage":"1","endPage":"12","ipdsId":"IP-092651","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":468353,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.rse.2018.09.005","text":"Publisher Index Page"},{"id":357942,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oklahoma","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -100,\n              34\n            ],\n            [\n              -96,\n              34\n            ],\n            [\n              -96,\n              37\n            ],\n            [\n              -100,\n              37\n            ],\n            [\n              -100,\n              34\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"218","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5bc02f84e4b0fc368eb53873","contributors":{"authors":[{"text":"Barnhart, William D. 0000-0003-0498-1697","orcid":"https://orcid.org/0000-0003-0498-1697","contributorId":192730,"corporation":false,"usgs":false,"family":"Barnhart","given":"William D.","affiliations":[],"preferred":false,"id":746822,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yeck, William L. 0000-0002-2801-8873 wyeck@usgs.gov","orcid":"https://orcid.org/0000-0002-2801-8873","contributorId":147558,"corporation":false,"usgs":true,"family":"Yeck","given":"William","email":"wyeck@usgs.gov","middleInitial":"L.","affiliations":[{"id":309,"text":"Geology and Geophysics Science Center","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":746823,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McNamara, Daniel E. 0000-0001-6860-0350 mcnamara@usgs.gov","orcid":"https://orcid.org/0000-0001-6860-0350","contributorId":402,"corporation":false,"usgs":true,"family":"McNamara","given":"Daniel","email":"mcnamara@usgs.gov","middleInitial":"E.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":746824,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Issues with U.S. and global markets for helium include inelastic demand, economic availability of helium only as a byproduct, only 4–5 major producers, helium’s propensity to escape earth’s crust, an ongoing absence of storage facilities comparable to the FHR, and a lack of consequences for the venting of helium. The complex combination of these economic, physical, and regulatory issues is unique to helium, and determining helium’s practical availability goes far beyond estimating the technically accessible volume of underground resources. Although most of these issues have been analyzed since helium was recognized to be a valuable mineral commodity in the early 1900s, very few economic models have been developed that adequately consider the unique characteristics of helium and helium markets. In particular, there is a notable lack of recent empirical work to estimate the responsiveness of helium demand, supply, prices, and trade patterns to the ongoing drawdown and sale of helium reserves stored in the FHR. In general, existing models of helium either do not account for an oligopoly controlling supply, or they do not evaluate potential helium extraction and storage programs based on an intertemporal maximization of the value of the resource. Such models could be of very limited use to decision makers. This review found only one working paper with a helium market model that has incorporated both of these vital considerations. That and other economic studies along similar lines could be very useful in helping inform current helium policy discussions and decisions.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s11053-017-9359-y","usgsCitation":"Anderson, S.T., 2018, Economics, helium, and the U.S. Federal Helium Reserve: Summary and outlook: Natural Resources Research, v. 27, no. 4, p. 455-477, https://doi.org/10.1007/s11053-017-9359-y.","productDescription":"23 p.","startPage":"455","endPage":"477","ipdsId":"IP-080164","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":460835,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s11053-017-9359-y","text":"Publisher Index Page"},{"id":357940,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"4","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2017-12-05","publicationStatus":"PW","scienceBaseUri":"5bc02f84e4b0fc368eb53875","contributors":{"authors":[{"text":"Anderson, Steven T. 0000-0003-3481-3424 sanderson@usgs.gov","orcid":"https://orcid.org/0000-0003-3481-3424","contributorId":2532,"corporation":false,"usgs":true,"family":"Anderson","given":"Steven","email":"sanderson@usgs.gov","middleInitial":"T.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":746709,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

There is growing concern over what kinds and amounts of fire will achieve desirable outcomes and limit harmful effects on people and nature. Moreover, the increasing complexity surrounding cost and management of wildfires suggests that science should play a more prominent role in informing decisions about the need for fire in nature, and the need for society to adapt to the inevitable occurrence of different kinds and amounts of fire and smoke. </p><p>Scientists widely view the natural wildfire regime as essential to western US forest ecosystem functioning. However, debates continue over how much low-, moderate-, and high severity fire is “natural” or desirable in these forests. Ongoing disagreement centers on the characteristics and importance of historical proportions and patch size distributions of low-, moderate-, and high-severity fires of dry, moist, and cold forests, and on the ecological consequences of changing fire-patch patterns and relative abundances. Scientists also debate the relative importance of climate and extreme weather versus fuel as drivers of high-severity fire, as well as the effectiveness and value of fuel treatments for reducing risks of undesired fire effects.<br></p><p>Climate research shows that we should expect shifting future climates in all ecoregions. These expected changes make it difficult for scientists, land managers, and decision-makers to know the degree to which future forest management should be informed by historical conditions. There also is disagreement about how to make western forests more resilient to future disruptions in both climatic and fire regimes. To complicate matters, areas of scientific agreement -- the “common ground” shared by those in the research community -- are poorly articulated. Thus, the focus of the Fire Research Consensus (FRC) project has been to identify common ground among scientists, and provide a summary that can inform management. Land and fire managers are one audience for this report, as are stakeholders and the interested public.</p><p><br>Our analysis, which results from extensive scientific literature reviews and questionnaires sent to western fire scientists and land managers, is summarized in nine key<br>topics:<br>A. Fire history and fire ecology vary with geography.<br>B. Human impacts and management history vary with geography.<br>C. Fire is a keystone process, which occurs in almost all western US forest types.<br>D. Knowledge of historical range of variability (HRV) is useful but does not dictate land<br>management goals.<br>E. Forest structure, composition, and fuels have changed, affecting burn severity and<br>fire extent.<br>F. Climate and fuels both influence current fire sizes and their severities.<br>G. The role of changing climatic conditions is increasingly important.<br>H. Multiple fire ecology and fire history research approaches can be useful for<br>characterizing fire regimes.<br>I. Many existing fire management tools and strategies can be useful moving forward.</p><p>We found much common ground that will be useful to scientists, managers, citizens, and policy decision-makers. For example, there is wide agreement among scientists that fire is one of the most essential influences on western forests and that more fire is needed on most landscapes, but not all wildfire behavior or extent will do. Fires can produce more positive benefits and fewer negative impacts when they burn with an ecologically appropriate mix and pattern of low, moderate, and high severity. Managers will need assistance and funding to create landscape conditions that favor more desirable fire behavior at broad spatial scales. Note that much societal impact from western wildfires occurs in non-forested landscapes that are not covered in this report, where findings would differ from those reported here for forested landscapes. We summarize additional key points below. </p>","language":"English","publisher":"National Center for Ecological Analysis and Synthesis","usgsCitation":"Moritz, M.A., Topik, C., Allen, C.D., Hessburg, P.F., Morgan, P., Odion, D.C., Veblen, T.T., and McCullough, I.M., 2018, A statement of common ground regarding the role of wildfire in forested landscapes of the western United States: Final Report, 55 p.","productDescription":"55 p.","ipdsId":"IP-099757","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":382548,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":382533,"type":{"id":15,"text":"Index Page"},"url":"https://www.nceas.ucsb.edu/snapp/fire-research-consensus"}],"country":"United States","otherGeospatial":"Western United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.71679687499999,\n              31.952162238024975\n            ],\n            [\n              -103.095703125,\n              31.952162238024975\n            ],\n            [\n              -103.095703125,\n              48.69096039092549\n            ],\n            [\n              -124.71679687499999,\n              48.69096039092549\n            ],\n            [\n              -124.71679687499999,\n              31.952162238024975\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Moritz, Max A.","contributorId":182434,"corporation":false,"usgs":false,"family":"Moritz","given":"Max","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":808909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Topik, Chris","contributorId":248342,"corporation":false,"usgs":false,"family":"Topik","given":"Chris","email":"","affiliations":[{"id":49864,"text":"The Nature Conservancy, North America Forest Restoration Program","active":true,"usgs":false}],"preferred":false,"id":808910,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Allen, Craig D. 0000-0002-8777-5989 craig_allen@usgs.gov","orcid":"https://orcid.org/0000-0002-8777-5989","contributorId":2597,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"craig_allen@usgs.gov","middleInitial":"D.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":true,"id":808911,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hessburg, Paul F.","contributorId":46481,"corporation":false,"usgs":false,"family":"Hessburg","given":"Paul","email":"","middleInitial":"F.","affiliations":[{"id":12647,"text":"U.S. Forest Service, Pacific Northwest Research Station","active":true,"usgs":false}],"preferred":false,"id":808912,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Morgan, Penelope","contributorId":127585,"corporation":false,"usgs":false,"family":"Morgan","given":"Penelope","email":"","affiliations":[],"preferred":false,"id":808913,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Odion, Dennis C.","contributorId":248343,"corporation":false,"usgs":false,"family":"Odion","given":"Dennis","email":"","middleInitial":"C.","affiliations":[{"id":28103,"text":"University of California - Santa Barbara","active":true,"usgs":false}],"preferred":false,"id":808914,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Veblen, Thomas T.","contributorId":218196,"corporation":false,"usgs":false,"family":"Veblen","given":"Thomas","email":"","middleInitial":"T.","affiliations":[{"id":36627,"text":"University of Colorado, Boulder","active":true,"usgs":false}],"preferred":false,"id":808915,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"McCullough, Ian M.","contributorId":149952,"corporation":false,"usgs":false,"family":"McCullough","given":"Ian","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":808916,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

However, if marks affect the vital rates or behavior of marked individuals, any conclusions reached by a study might be biased relative to the general population. Leg bands have rarely been found to have negative effects on birds and are frequently used to mark individuals. Leg flags, which are larger, heavier, and might produce more drag than bands, are commonly used on shorebirds and can help improve resighting rates. However, no one to date has assessed the possible effects of leg flags on the demographic performance of shorebirds. At seven sites in Arctic Alaska and western Canada, we marked individuals and monitored nest survival of four species of Arctic‐breeding shorebirds, including Semipalmated Sandpipers (</span><i>Calidris pusilla</i><span>), Western Sandpipers (</span><i>C.&nbsp;mauri</i><span>), Red‐necked Phalaropes (</span><i>Phalaropus lobatus</i><span>), and Red Phalaropes (</span><i>P.&nbsp;fulicarius</i><span>). We used a daily nest survival model in a Bayesian framework to test for effects of leg flags, relative to birds with only bands, on daily survival rates of 1952 nests. We found no evidence of a difference in nest survival between birds with flags and those with only bands. Our results suggest, therefore, that leg flags have little effect on the nest success of Arctic‐breeding sandpipers and phalaropes. Additional studies are needed, however, to evaluate the possible effects of flags on shorebirds that use other habitats and on survival rates of adults and chicks.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/jofo.12264","usgsCitation":"Weiser, E.L., Lanctot, R., Brown, S.C., Gates, H.R., Bentzen, R.L., Boldenow, M.L., Cunningham, J.A., Doll, A.C., Donnelly, T., English, W.B., Franks, S.E., Grond, K., Herzog, P., Hill, B.L., Kendall, S.J., Kwon, E., Lank, D.B., Liebezeit, J.R., Rausch, J., Saalfeld, S.T., Taylor, A.R., Ward, D.H., Wood, P., and Sandercock, B.K., 2018, Effects of leg flags on nest survival of four species of Arctic‐breeding shorebirds: Journal of Field Ornithology, v. 89, no. 3, p. 287-297, https://doi.org/10.1111/jofo.12264.","productDescription":"11 p.","startPage":"287","endPage":"297","ipdsId":"IP-098142","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":468364,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1111/jofo.12264","text":"External Repository"},{"id":357846,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"89","issue":"3","publishingServiceCenter":{"id":15,"text":"Madison PSC"},"noUsgsAuthors":false,"publicationDate":"2018-09-23","publicationStatus":"PW","scienceBaseUri":"5bc02f88e4b0fc368eb53891","contributors":{"authors":[{"text":"Weiser, Emily L. 0000-0003-1598-659X","orcid":"https://orcid.org/0000-0003-1598-659X","contributorId":206605,"corporation":false,"usgs":true,"family":"Weiser","given":"Emily","email":"","middleInitial":"L.","affiliations":[{"id":65299,"text":"Alaska Science Center Ecosystems","active":true,"usgs":true}],"preferred":true,"id":746438,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lanctot, Richard B.","contributorId":77879,"corporation":false,"usgs":false,"family":"Lanctot","given":"Richard B.","affiliations":[{"id":6987,"text":"U.S. Fish and Wildlife Sevice","active":true,"usgs":false}],"preferred":false,"id":746439,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, Stephen C. 0000-0002-0421-1660","orcid":"https://orcid.org/0000-0002-0421-1660","contributorId":208214,"corporation":false,"usgs":false,"family":"Brown","given":"Stephen","email":"","middleInitial":"C.","affiliations":[{"id":37764,"text":"Shorebird Recovery Program","active":true,"usgs":false}],"preferred":false,"id":746440,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gates, H.

The extended marigram encompasses the time of the great 1945 Makran earthquake of early November 28, local time, and of the ensuing tsunami, which continued into November 29. The marigram was published previously as a 9-h excerpt that begins 1&nbsp;h after the earthquake. The full marigram presented here covers most of 17&nbsp;days from November 15 to December 1. Gaps include a tsunami-induced outage that may help explain why the highest water level gauged is 1&nbsp;m below the maximum water level reported nearby. The detiding method computes a reference tidal curve that disregards all observations from November 28 and 29.

This can result in underestimates of occupancy, where nondetection is conflated with absence. The site occupancy model (SOM) overcomes this failure by treating occupancy as a latent variable of the model and incorporates a detection submodel to account for variability in detection rates. These have rarely been applied in the context of marine fish and never for the multiseason dynamic occupancy model (DOM). In this study, a DOM is developed for a designated species of concern, cusk (</span><i>Brosme brosme</i><span>), over a four-season period. Making novel use of a high-resolution 3-dimensional hydrodynamic model, detectability of cusk is considered as a function of current speed and algae cover. Algal cover on the seabed is measured from video surveys to divide the study area into two distinct regions: those with canopy forming species of algae and those without (henceforth bottom types). Modeled estimates of the proportion of sites occupied in each season are 0.88, 0.45, 0.74, and 0.83. These are significantly greater than the proportion of occupied sites measured from underwater video observations which are 0.57, 0.28, 0.43, and 0.57. Individual fish are detected more frequently with increasing current speed in areas lacking canopy and less frequently with increasing current speed in areas with canopy. The results indicate that, where possible, SDM studies for all marine species should take account of detectability to avoid underestimating the proportion of sites occupied at a given study area. Sampling closed areas or areas of conservation often requires the use of nonphysical, low impact sampling methods like camera surveys. These methods inherently result in detection probabilities less than one, an issue compounded by time-varying features of the environment that are rarely accounted for marine studies. This work highlights the use of modeled hydrodynamics as a tool to correct some of this imbalance.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/ece3.4493","usgsCitation":"Calvert, J., McGonigle, C., Sethi, S., Harris, B., Quinn, R., and Grabowski, J., 2018, Dynamic occupancy modeling of temperate marine fish in area-based closures: Ecology and Evolution, v. 8, no. 20, p. 10192-10205, https://doi.org/10.1002/ece3.4493.","productDescription":"14 p.","startPage":"10192","endPage":"10205","ipdsId":"IP-127035","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":468378,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ece3.4493","text":"Publisher Index Page"},{"id":397252,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Gulf of Maine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -68.983333,\n              43\n            ],\n            [\n              -68.916667,\n              43\n            ],\n            [\n              -68.916667,\n              42.88\n            ],\n            [\n              -68.983333,\n              42.88\n            ],\n            [\n              -68.983333,\n              43\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"8","issue":"20","noUsgsAuthors":false,"publicationDate":"2018-09-21","publicationStatus":"PW","contributors":{"authors":[{"text":"Calvert, Jay","contributorId":288770,"corporation":false,"usgs":false,"family":"Calvert","given":"Jay","email":"","affiliations":[{"id":61838,"text":"University of Ulster","active":true,"usgs":false}],"preferred":false,"id":838269,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McGonigle, Chris","contributorId":288771,"corporation":false,"usgs":false,"family":"McGonigle","given":"Chris","email":"","affiliations":[{"id":61838,"text":"University of Ulster","active":true,"usgs":false}],"preferred":false,"id":838270,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sethi, Suresh 0000-0002-0053-1827 ssethi@usgs.gov","orcid":"https://orcid.org/0000-0002-0053-1827","contributorId":191424,"corporation":false,"usgs":true,"family":"Sethi","given":"Suresh","email":"ssethi@usgs.gov","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":838268,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Harris, Bradley","contributorId":288772,"corporation":false,"usgs":false,"family":"Harris","given":"Bradley","affiliations":[{"id":12915,"text":"Alaska Pacific University","active":true,"usgs":false}],"preferred":false,"id":838271,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Quinn, Rory","contributorId":288773,"corporation":false,"usgs":false,"family":"Quinn","given":"Rory","email":"","affiliations":[{"id":61838,"text":"University of Ulster","active":true,"usgs":false}],"preferred":false,"id":838272,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Grabowski, Jon","contributorId":288774,"corporation":false,"usgs":false,"family":"Grabowski","given":"Jon","email":"","affiliations":[{"id":61840,"text":"Northeaster University","active":true,"usgs":false}],"preferred":false,"id":838273,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Taken in context with other potential fault‐related lineaments along the Entiat fault, our interpretation of Holocene earthquakes in Swakane canyon could suggest reactivation of longer sections of the Entiat fault, as well as of other bedrock faults in the eastern Cascades. Although active erosion and slow strain rates lead to a subdued geomorphic expression of recent deformation, we conclude that the reactivated Entiat fault represents a seismogenic structure that should be considered in regional seismic hazard analyses. The difficulty of recognizing low‐slip‐rate structures in forested and mountainous terrain underscores the importance of additional lidar surveys and geological and geophysical studies for fully understanding seismic hazard in regions with infrequent but potentially large earthquakes.</span></p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120170228","usgsCitation":"Carlson, B.L., Schermer, E.R., Amos, C.B., Stephenson, W.J., Sherrod, B.L., and Mahan, S.A., 2018, Holocene fault reactivation in the eastern Cascades, Washington: Bulletin of the Seismological Society of America, v. 108, no. 5A, p. 2614-2633, https://doi.org/10.1785/0120170228.","productDescription":"20 p.","startPage":"2614","endPage":"2633","ipdsId":"IP-098702","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":357408,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -125.17822265625,\n              45.537136680398596\n            ],\n            [\n              -118,\n              45.537136680398596\n            ],\n            [\n              -118,\n              49.001843917978526\n            ],\n            [\n              -125.17822265625,\n              49.001843917978526\n            ],\n            [\n              -125.17822265625,\n              45.537136680398596\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"108","issue":"5A","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2018-08-21","publicationStatus":"PW","scienceBaseUri":"5bc02f9de4b0fc368eb538ff","contributors":{"authors":[{"text":"Carlson, Benjamin L.","contributorId":207530,"corporation":false,"usgs":false,"family":"Carlson","given":"Benjamin","email":"","middleInitial":"L.","affiliations":[{"id":37554,"text":"Xerces Society","active":true,"usgs":false}],"preferred":false,"id":745241,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schermer, Elizabeth R.","contributorId":184060,"corporation":false,"usgs":false,"family":"Schermer","given":"Elizabeth","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":745242,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Amos, Colin B.","contributorId":62127,"corporation":false,"usgs":true,"family":"Amos","given":"Colin","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":745243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stephenson, William J. 0000-0001-8699-0786 wstephens@usgs.gov","orcid":"https://orcid.org/0000-0001-8699-0786","contributorId":695,"corporation":false,"usgs":true,"family":"Stephenson","given":"William","email":"wstephens@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":745244,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sherrod, Brian L. 0000-0002-4492-8631 bsherrod@usgs.gov","orcid":"https://orcid.org/0000-0002-4492-8631","contributorId":2834,"corporation":false,"usgs":true,"family":"Sherrod","given":"Brian","email":"bsherrod@usgs.gov","middleInitial":"L.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":745245,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mahan, Shannon A. 0000-0001-5214-7774 smahan@usgs.gov","orcid":"https://orcid.org/0000-0001-5214-7774","contributorId":147159,"corporation":false,"usgs":true,"family":"Mahan","given":"Shannon","email":"smahan@usgs.gov","middleInitial":"A.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":745246,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Large‐scale restoration projects, such as the one evaluated here, are primarily designed to rehabilitate and enhance fish and wildlife habitat. We determined whether an individual restoration project, construction of an island complex, fulfilled a programmatic goal of re‐establishing diverse and abundant native aquatic vegetation. Eighteen years of aquatic vegetation monitoring data from impact and reference areas were compared to evaluate the anticipated direct effects (within 400&nbsp;m of the constructed islands) and indirect effects (&gt;400&nbsp;m downstream of constructed islands) of restoration. Impact areas were also compared with an unrestored negative reference area ~200&nbsp;km downstream of the project and with a positive reference area in adjacent, relatively natural backwaters. Only indirect effects of restoration were evident. Prevalence and species richness of aquatic vegetation in both of the impact areas and in the negative reference area increased prior to restoration, suggesting large‐scale improvement independent of the project examined here. Indirect effects were demonstrated as further increases in both prevalence and species richness coinciding with restoration in the area &gt;400&nbsp;m downstream of the restoration.

These rapid variations in marine radiocarbon age suggest that marine radiocarbon dates from environments with variable upwelling could be skewed by up to hundreds of years.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/15564894.2017.1338316","usgsCitation":"Jones, K.B., Hodgins, G.W., and Sandweiss, D.H., 2018, Radiocarbon chronometry of Site QJ-280, Quebrada Jaguay, a terminal Pleistocene to early Holocene fishing site in southern Peru: Journal of Island and Coastal Archaeology, v. 14, no. 1, p. 82-100, https://doi.org/10.1080/15564894.2017.1338316.","productDescription":"19 p.","startPage":"82","endPage":"100","ipdsId":"IP-083259","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":357292,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Peru","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-69.59042,-17.58001],[-69.85844,-18.09269],[-70.37257,-18.34798],[-71.37525,-17.7738],[-71.46204,-17.36349],[-73.44453,-16.35936],[-75.23788,-15.26568],[-76.00921,-14.64929],[-76.42347,-13.82319],[-76.25924,-13.53504],[-77.10619,-12.22272],[-78.09215,-10.37771],[-79.03695,-8.38657],[-79.44592,-7.93083],[-79.76058,-7.19434],[-80.53748,-6.54167],[-81.25,-6.13683],[-80.92635,-5.69056],[-81.41094,-4.73676],[-81.09967,-4.03639],[-80.30256,-3.40486],[-80.18401,-3.82116],[-80.46929,-4.05929],[-80.44224,-4.42572],[-80.02891,-4.34609],[-79.62498,-4.4542],[-79.20529,-4.95913],[-78.6399,-4.54778],[-78.45068,-3.8731],[-77.8379,-3.00302],[-76.63539,-2.60868],[-75.545,-1.56161],[-75.23372,-0.91142],[-75.37322,-0.15203],[-75.10662,-0.05721],[-74.4416,-0.53082],[-74.1224,-1.00283],[-73.6595,-1.26049],[-73.07039,-2.30895],[-72.32579,-2.43422],[-71.77476,-2.16979],[-71.41365,-2.3428],[-70.81348,-2.25686],[-70.04771,-2.72516],[-70.69268,-3.74287],[-70.39404,-3.76659],[-69.89364,-4.29819],[-70.79477,-4.25126],[-70.92884,-4.40159],[-71.74841,-4.59398],[-72.89193,-5.27456],[-72.96451,-5.74125],[-73.21971,-6.08919],[-73.12003,-6.62993],[-73.72449,-6.9186],[-73.7234,-7.341],[-73.98724,-7.52383],[-73.57106,-8.42445],[-73.01538,-9.03283],[-73.22671,-9.46221],[-72.56303,-9.52019],[-72.18489,-10.0536],[-71.30241,-10.07944],[-70.48189,-9.49012],[-70.54869,-11.00915],[-70.09375,-11.12397],[-69.52968,-10.95173],[-68.66508,-12.5613],[-68.88008,-12.89973],[-68.92922,-13.60268],[-68.94889,-14.45364],[-69.33953,-14.9532],[-69.16035,-15.32397],[-69.38976,-15.66013],[-68.95964,-16.5007],[-69.59042,-17.58001]]]},\"properties\":{\"name\":\"Peru\"}}]}","volume":"14","issue":"1","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2017-06-28","publicationStatus":"PW","scienceBaseUri":"5bc02fa0e4b0fc368eb53921","contributors":{"authors":[{"text":"Jones, Kevin B. 0000-0002-6386-2623 kevinjones@usgs.gov","orcid":"https://orcid.org/0000-0002-6386-2623","contributorId":565,"corporation":false,"usgs":true,"family":"Jones","given":"Kevin","email":"kevinjones@usgs.gov","middleInitial":"B.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":744894,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hodgins, Gregory W.

We used two heat-based indices of spring onset, the First Leaf Index (FLI) and the First Bloom Index (FBI), as proxies of habitat change for the period 1901 to 2012 at three spatial scales: the US National Wildlife Refuge System; the four major bird migratory flyways in North America; and the seasonal ranges (i.e., breeding and non-breeding grounds) of two migratory bird species, Blue-winged Warbler (</span><i>Vermivora cyanoptera</i><span>) and Whooping Crane (</span><i>Grus americana</i><span>). Our results show that relative to the historical range of variability, the onset of spring is now earlier in 76% of all wildlife refuges and extremely early (i.e., exceeding 95% of historical conditions) in 49% of refuges. In all flyways but the Pacific, the rate of spring advance is generally greater at higher latitudes than at lower latitudes. This differential rate of advance in spring onset is most pronounced in the Atlantic flyway, presumably because of a “warming hole” in the southeastern US. Both FLI and FBI have advanced markedly in the breeding ranges–but not the non-breeding ranges–of the two selected bird species, albeit with considerable intra-range variation. Differences among species in terms of migratory patterns and the location and extent of seasonal habitats, as well as shifts in habitat conditions over time, may complicate predictions of the vulnerability of migratory birds to climate change effects. This study provides insight into how differential shifts in the phenology of disparate but linked habitats could inform local- to landscape-scale management strategies for the conservation of migratory bird populations.</span></p>","language":"English","publisher":"PLOS","doi":"10.1371/journal.pone.0202495","usgsCitation":"Waller, E.K., Crimmins, T.M., Walker, J., Posthumus, E.E., and Weltzin, J., 2018, Differential changes in the onset of spring across US National Wildlife Refuges and North American migratory bird flyways: PLoS ONE, v. 13, no. 9, p. 1-24, https://doi.org/10.1371/journal.pone.0202495.","productDescription":"e0202495; 24 p.","startPage":"1","endPage":"24","ipdsId":"IP-094003","costCenters":[{"id":433,"text":"National Phenology Network","active":true,"usgs":true}],"links":[{"id":468408,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0202495","text":"Publisher Index Page"},{"id":357290,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"9","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2018-09-12","publicationStatus":"PW","scienceBaseUri":"5bc02fa1e4b0fc368eb53929","contributors":{"authors":[{"text":"Waller, Eric K. 0000-0002-9169-9210","orcid":"https://orcid.org/0000-0002-9169-9210","contributorId":203496,"corporation":false,"usgs":true,"family":"Waller","given":"Eric","email":"","middleInitial":"K.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true},{"id":433,"text":"National Phenology Network","active":true,"usgs":true}],"preferred":true,"id":744839,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crimmins, Theresa M.","contributorId":178236,"corporation":false,"usgs":false,"family":"Crimmins","given":"Theresa","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":744840,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Walker, Jessica J. 0000-0002-3225-0317","orcid":"https://orcid.org/0000-0002-3225-0317","contributorId":207373,"corporation":false,"usgs":true,"family":"Walker","given":"Jessica J.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":744841,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Posthumus, Erin E. 0000-0003-3855-2380","orcid":"https://orcid.org/0000-0003-3855-2380","contributorId":204418,"corporation":false,"usgs":false,"family":"Posthumus","given":"Erin","email":"","middleInitial":"E.","affiliations":[{"id":40537,"text":"USA National Phenology Network, National Coordinating Office; University of Arizona, School of Natural Resources and the Environment","active":true,"usgs":false}],"preferred":false,"id":744842,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Weltzin, Jake 0000-0001-8641-6645 jweltzin@usgs.gov","orcid":"https://orcid.org/0000-0001-8641-6645","contributorId":196323,"corporation":false,"usgs":true,"family":"Weltzin","given":"Jake","email":"jweltzin@usgs.gov","affiliations":[{"id":433,"text":"National Phenology Network","active":true,"usgs":true},{"id":506,"text":"Office of the AD Ecosystems","active":true,"usgs":true}],"preferred":true,"id":744843,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Thus, we sought to provide a numerical estimate of major water budget components on tribal lands within the conterminous US and on USGS hydrologic unit codes (HUC2) regions. Using existing national-scale data and models, we estimated mean annual precipitation, evapotranspiration, excess precipitation, streamflow, and water use for the period 1971–2000. Tribal lands represent about 3.4 percent of the total land area of the conterminous US and on average account for 1.9 percent of precipitation, 2.4 percent of actual evapotranspiration, 0.95 percent of excess precipitation, 1.6 percent of water use, and 0.43 percent of streamflow origination. Additionally, approximately 9.5 and 11.3 percent of US streamflow flows through or adjacent as boundaries to tribal lands, respectively. Streamflow through or adjacent to tribal lands accounts for 42 and 48 percent of streamflow in the Missouri region, respectively; and for 86 and 88 percent in the Lower Colorado region, respectively. On average, 5,600 million cubic meters of streamflow per year was produced on tribal lands in the Pacific Northwest region, nearly five times greater than tribal lands in any other region. Tribal lands in the Great Lakes, Missouri, Arkansas-White-Red, and California regions all produced between 1,000 and 1,400 million cubic meters per year.</span></p>","language":"English","publisher":"PLOS","doi":"10.1371/journal.pone.0203872","usgsCitation":"Blasch, K.W., Hundt, S., Wurster, P., Sando, R., and Berthelote, A., 2018, Streamflow contributions from tribal lands to major river basins of the United States: PLoS ONE, v. 13, no. 9, p. 1-16, https://doi.org/10.1371/journal.pone.0203872.","productDescription":"e0203872; 16 p.","startPage":"1","endPage":"16","ipdsId":"IP-089346","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":468411,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0203872","text":"Publisher Index Page"},{"id":357234,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"13","issue":"9","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2018-09-11","publicationStatus":"PW","scienceBaseUri":"5b98a25fe4b0702d0e842e3e","contributors":{"authors":[{"text":"Blasch, Kyle W. 0000-0002-0590-0724","orcid":"https://orcid.org/0000-0002-0590-0724","contributorId":203415,"corporation":false,"usgs":true,"family":"Blasch","given":"Kyle","email":"","middleInitial":"W.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":744764,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hundt, Stephen A. 0000-0002-6484-0637","orcid":"https://orcid.org/0000-0002-6484-0637","contributorId":204678,"corporation":false,"usgs":true,"family":"Hundt","given":"Stephen","middleInitial":"A.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":744765,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wurster, Patrick 0000-0003-2668-2014","orcid":"https://orcid.org/0000-0003-2668-2014","contributorId":207806,"corporation":false,"usgs":false,"family":"Wurster","given":"Patrick","email":"","affiliations":[{"id":685,"text":"Wyoming-Montana Water Science Center","active":false,"usgs":true}],"preferred":false,"id":744766,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sando, Roy 0000-0003-0704-6258","orcid":"https://orcid.org/0000-0003-0704-6258","contributorId":3874,"corporation":false,"usgs":true,"family":"Sando","given":"Roy","email":"","affiliations":[{"id":685,"text":"Wyoming-Montana Water Science Center","active":false,"usgs":true}],"preferred":true,"id":744767,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Berthelote, Antony","contributorId":207807,"corporation":false,"usgs":false,"family":"Berthelote","given":"Antony","email":"","affiliations":[{"id":37636,"text":"Salish Kootenai College","active":true,"usgs":false}],"preferred":false,"id":744768,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
