These challenges are illustrated in this assessment of tsunami hazard to the U.S. Atlantic margin. Seismic activity along the U.S. Atlantic margin in general is low, and confirmed paleo-tsunami deposits have not yet been found, suggesting a very low rate of hazard. However, the devastating 1929 Grand Banks tsunami along the Atlantic margin of Canada shows that these events continue to occur. Densely populated areas, extensive industrial and port facilities, and the presence of ten nuclear power plants along the coast, make this region highly vulnerable to flooding by tsunamis and therefore even low-probability events need to be evaluated.</p>\n<p>We can presently draw several tentative conclusions regarding tsunami hazard to the U.S. Atlantic coast. Landslide tsunamis likely constitute the biggest tsunami hazard to the coast. Only a small number of landslides have so far been dated and they are generally older than 10,000 years. The geographical distribution of landslides along the margin is expected to be uneven and to depend on the distribution of seismic activity along the margin and on the geographical distribution of Pleistocene sediment. We do not see evidence that gas hydrate dissociation contributes to the generation of landslides along the U.S. Atlantic margin. Analysis of landslide statistics along the fluvial and glacial portions of the margin indicate that most of the landslides are translational, were probably initiated by seismic acceleration, and failed as aggregate slope failures. How tsunamis are generated from aggregate landslides remains however, unclear. Estimates of the recurrence interval of earthquakes along the continental slope may provide maximum estimates for the recurrence interval of landslide along the margin.</p>\n<p>Tsunamis caused by atmospheric disturbances and by coastal earthquakes may be more frequent than those generated by landslides, but their amplitudes are probably smaller. Among the possible far-field earthquake sources, only earthquakes located within the Gulf of Cadiz or west of the Tore-Madeira Rise are likely to affect the U.S. coast. It is questionable whether earthquakes on the Puerto Rico Trench are capable of producing a large enough tsunami that will affect the U.S. Atlantic coast. More information is needed to evaluate the seismic potential of the northern Cuba fold-and-thrust belt. The hazard from a volcano flank collapse in the Canary Islands is likely smaller than originally stated, and there is not enough information to evaluate the magnitude and frequency of flank collapse from the Azores Islands. Both deterministic and probabilistic methods to evaluate the tsunami hazard from the margin are available for application to the Atlantic margin, but their implementation requires more information than is currently available.</p>","language":"English","publisher":"Elsevier Scientific Pub.

Ruapehu","docAbstract":"Between 27 and 11 cal. ka BP, a transition is observed in Plinian eruptions at Mt. Ruapehu, indicating evolution from non-collapsing (steady and oscillatory) eruption columns to partially collapsing columns (both wet and dry). To determine the causes of these variations over this eruptive interval, we examined lapilli fall deposits from four eruptions representing the climactic phases of each column type. All eruptions involve andesite to basaltic andesite magmas containing plagioclase, clinopyroxene, orthopyroxene and magnetite phenocrysts. Differences occur in the dominant pumice texture, the degree of bulk chemistry and textural variability, the average microcrystallinity and the composition of groundmass glass. In order to investigate the role of ascent and degassing processes on column stability, vesicle textures were quantified by gas volume pycnometry (porosity), X-ray synchrotron and computed microtomography (μ-CT) imagery from representative clasts from each eruption. These data were linked to groundmass crystallinity and glass geochemistry. Pumice textures were classified into six types (foamy, sheared, fibrous, microvesicular, microsheared and dense) according to the vesicle content, size and shape and microlite content. Bulk porosities vary from 19 to 95 % among all textural types. Melt-referenced vesicle number density ranges between 1.8 × 10<sup>2</sup> and 8.9 × 10<sup>2</sup> mm<sup>−3</sup>, except in fibrous textures, where it spans from 0.3 × 10<sup>2</sup> to 53 × 10<sup>2</sup> mm</sup>−3</sup>. Vesicle-free magnetite number density varies within an order of magnitude from 0.4 × 10<sup>2</sup> to 4.5 × 10<sup>2</sup> mm<sup>−3</sup> in samples with dacitic groundmass glass and between 0.0 and 2.3 × 10<sup>2</sup> mm<sup>−3</sup> in samples with rhyolitic groundmass. The data indicate that columns that collapsed to produce pyroclastic flows contained pumice with the greatest variation in bulk composition (which overlaps with but extends to slightly more silicic compositions than other eruptive products); textures indicating heterogeneous bubble nucleation, progressively more complex growth history and shear-localization; and the highest degrees of microlite crystallization, most evolved melt compositions and lowest relative temperatures. These findings suggest that collapsing columns in Ruapehu have been produced when strain localization is prominent, early bubble nucleation occurs and variation in decompression rate across the conduit is greatest. This study shows that examination of pumice from steady phases that precede column collapse may be used to predict subsequent column behaviour.","language":"English","publisher":"Springer","doi":"10.1007/s00445-014-0822-x","usgsCitation":"Pardo, N., Cronin, S.J., Wright, H.M., Schipper, C.I., Smith, I., and Stewart, B., 2014, Pyroclast textural variation as an indicator of eruption column steadiness in andesitic Plinian eruptions at Mt.

New U-Pb magmatic, detrital zircon, and <sup>40</sup>Ar/<sup>39</sup>Ar ages constrained by detailed field mapping, global nannoplankton zones, and magnetic polarities allow correlation of the volcanics with the 2012 geologic time scale. The data show that Siletzia was rapidly erupted 56–49 Ma, during the Chron 25–22 plate reorganization in the northeast Pacific basin. Accretion was completed between 51 and 49 Ma in Oregon, based on CP11 (CP—Coccolith Paleogene zone) coccoliths in strata overlying onlapping continental sediments. Magmatism continued in the northern Oregon Coast Range until ca. 46 Ma with the emplacement of a regional sill complex during or shortly after accretion. Isotopic signatures similar to early Columbia River basalts, the great crustal thickness of Siletzia in Oregon, rapid eruption, and timing of accretion are consistent with offshore formation as an oceanic plateau. Approximately 8 m.y. after accretion, margin parallel extension of the forearc, emplacement of regional dike swarms, and renewed magmatism of the Tillamook episode peaked at 41.6 Ma (CP zone 14a; Chron 19r). We examine the origin of Siletzia and consider the possible role of a long-lived Yellowstone hotspot using the reconstruction in GPlates, an open source plate model. In most hotspot reference frames, the Yellowstone hotspot (YHS) is on or near an inferred northeast-striking Kula-Farallon and/or Resurrection-Farallon ridge between 60 and 50 Ma. In this configuration, the YHS could have provided a 56–49 Ma source on the Farallon plate for Siletzia, which accreted to North America by 50 Ma. A sister plateau, the Eocene basalt basement of the Yakutat terrane, now in Alaska, formed contemporaneously on the adjacent Kula (or Resurrection) plate and accreted to coastal British Columbia at about the same time. Following accretion of Siletzia, the leading edge of North America overrode the YHS ca. 42 Ma. The voluminous high-Ti basaltic to alkalic magmatism of the 42–35 Ma Tillamook episode and extension in the forearc may be related to the encounter with an active YHS. Clockwise rotation of western Oregon about a pole in the backarc has since moved the Tillamook center and underlying Siletzia northward ∼250 km from the probable hotspot track on North America. In the reference frames we examined, the YHS arrives in the backarc ∼5 m.y. too early to match the 17 Ma magmatic flare-up commonly attributed to the YHS. We suggest that interaction with the subducting slab may have delayed arrival of the plume beneath the backarc.","language":"English","publisher":"Geological Society of America","doi":"10.1130/GES01018.1","usgsCitation":"Wells, R., Bukry, D., Friedman, R., Pyle, D., Duncan, R., Haeussler, P.J., and Wooden, J., 2014, Geologic history of Siletzia, a large igneous province in the Oregon and Washington Coast Range: Correlation to the geomagnetic polarity time scale and implications for a long-lived Yellowstone hotspot: Geosphere, v. 10, no. 4, p. 692-719, https://doi.org/10.1130/GES01018.1.","productDescription":"28 p.","startPage":"692","endPage":"719","numberOfPages":"28","ipdsId":"IP-052697","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":472904,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges01018.1","text":"Publisher Index Page"},{"id":291674,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Oregon, Vancouver, Washington","otherGeospatial":"Siletzia","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -158.0,40.0 ], [ -158.0,68.0 ], [ -114.0,68.0 ], [ -114.0,40.0 ], [ -158.0,40.0 ] ] ] } } ] }","volume":"10","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53e1efcbe4b0fe532be2de21","contributors":{"authors":[{"text":"Wells, Ray 0000-0002-7796-0160","orcid":"https://orcid.org/0000-0002-7796-0160","contributorId":71260,"corporation":false,"usgs":true,"family":"Wells","given":"Ray","affiliations":[],"preferred":false,"id":495998,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bukry, David 0000-0003-4540-890X","orcid":"https://orcid.org/0000-0003-4540-890X","contributorId":30980,"corporation":false,"usgs":true,"family":"Bukry","given":"David","affiliations":[],"preferred":false,"id":495995,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Friedman, Richard","contributorId":59363,"corporation":false,"usgs":true,"family":"Friedman","given":"Richard","affiliations":[],"preferred":false,"id":495997,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pyle, Douglas","contributorId":56985,"corporation":false,"usgs":true,"family":"Pyle","given":"Douglas","affiliations":[],"preferred":false,"id":495996,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Duncan, Robert","contributorId":74688,"corporation":false,"usgs":true,"family":"Duncan","given":"Robert","affiliations":[],"preferred":false,"id":495999,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Haeussler, Peter J. 0000-0002-1503-6247 pheuslr@usgs.gov","orcid":"https://orcid.org/0000-0002-1503-6247","contributorId":503,"corporation":false,"usgs":true,"family":"Haeussler","given":"Peter","email":"pheuslr@usgs.gov","middleInitial":"J.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":496000,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Wooden, Joe","contributorId":14313,"corporation":false,"usgs":true,"family":"Wooden","given":"Joe","affiliations":[],"preferred":false,"id":495994,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

However, much of historical big sagebrush vegetation has been removed or modified. Thus, regeneration is recognized as an important component for land management. Limited knowledge about key regeneration processes, however, represents an obstacle to identifying successful management practices and to gaining greater insight into the consequences of increasing disturbance frequency and global change. Therefore, our objective is to synthesize knowledge about natural big sagebrush regeneration. We identified and characterized the controls of big sagebrush seed production, germination, and establishment. The largest knowledge gaps and associated research needs include quiescence and dormancy of embryos and seedlings; variation in seed production and germination percentages; wet-thermal time model of germination; responses to frost events (including freezing/thawing of soils), CO<sub>2</sub> concentration, and nutrients in combination with water availability; suitability of microsite vs. site conditions; competitive ability as well as seedling growth responses; and differences among subspecies and ecoregions. Potential impacts of climate change on big sagebrush regeneration could include that temperature increases may not have a large direct influence on regeneration due to the broad temperature optimum for regeneration, whereas indirect effects could include selection for populations with less stringent seed dormancy. Drier conditions will have direct negative effects on germination and seedling survival and could also lead to lighter seeds, which lowers germination success further. The short seed dispersal distance of big sagebrush may limit its tracking of suitable climate; whereas, the low competitive ability of big sagebrush seedlings may limit successful competition with species that track climate. An improved understanding of the ecology of big sagebrush regeneration should benefit resource management activities and increase the ability of land managers to anticipate global change impacts.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Rangeland Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for Range Management","doi":"10.2111/REM-D-13-00079.1","usgsCitation":"Schlaepfer, D., Lauenroth, W.K., and Bradford, J.B., 2014, Natural regeneration processes in big sagebrush (<i>Artemisia tridentata</i>): Rangeland Ecology and Management, v. 67, no. 4, p. 344-357, https://doi.org/10.2111/REM-D-13-00079.1.","productDescription":"14 p.","startPage":"344","endPage":"357","numberOfPages":"14","ipdsId":"IP-042932","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":292279,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292243,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2111/REM-D-13-00079.1"}],"volume":"67","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53ef1ed5e4b0bfa1f993efd4","contributors":{"authors":[{"text":"Schlaepfer, Daniel R.","contributorId":105189,"corporation":false,"usgs":false,"family":"Schlaepfer","given":"Daniel R.","affiliations":[{"id":7098,"text":"University of Wyoming, Department of Botany, 1000 E.

We conducted a case study for Northern Pintails (hereafter pintail) in which we quantified regional and sub-regional economic values of subsistence harvest to indigenous communities in Arctic and sub-Arctic North America. As a first step, we used the replacement cost method to quantify the cost of replacing pintail subsistence harvest with the most similar commercially available protein (chicken). For an estimated annual subsistence harvest of ˜15,000 pintail, our mean estimate of the total replacement cost was ˜$63,000 yr<sup>−1</sup> ($2010 USD), with sub-regional values ranging from \\$263 yr<sup>−1</sup> to \\$21,930 yr<sup>−1</sup>.

The area mapped extends from northwestern Iran to southeastern Pakistan and includes volcanic and magmatic arcs that make up the Urumieh-Dokhtar volcanic belt (UDVB), the Chagai volcanic belt (CVB), and the central part of the Alborz magmatic belt (AMB). The volcanic belts span the Zagros-Makran transform zone and the present day Baluchistan (Makran) volcanic arc. ASTER visible near infrared (VNIR) data contain three bands between 0.52 and 0.86 micrometers (&mu;m) and the short-wave infrared (SWIR) data consist of six bands spanning 1.6 to 2.43 &mu;m with 15-meter (m), and 30-m resolution, respectively.</p>\n<p>&nbsp;</p>\n<p>During the 8-year project, three different calibration methods were used to correct ASTER SWIR anomalies and produce ASTER calibrated reflectance data, which were then used to map hydrothermally altered rocks. Logical operators, used to map hydrothermally altered rocks, perform multiple band ratios and thresholds that can be applied to multiple ASTER scenes using a single algorithm, thus eliminating separate production and application of vegetation and dark pixel masks. Argillic and phyllic band ratio logical operators use band ratios that define the 2.17- and 2.20-&mu;m absorption features to map kaolinite and alunite, typical in argillized rocks, and muscovite, which is a common mineral in phyllic alteration. Band thresholds for ratios in argillic and phyllic logical operator algorithms were determined by mapping known argillic and phyllic rocks at a calibration test site in Cuprite, Nevada, in the United States.</p>\n<p>&nbsp;</p>\n<p>The regional argillic and phyllic hydrothermal alteration map and geologic and deposit maps of the study area illustrate that distinct patterns of altered rocks are typically associated with certain types of mineral deposits. The central part of the UDVB contains numerous circular to elliptical patterns (1 to 5 kilometers in diameter) of mapped phyllic- and argillic-altered rocks associated with Eocene to Miocene intrusive igneous rocks, some of which host known porphyry copper deposits such as at Meiduk, Sar Cheshmeh, and Seridune in Iran. The Zagros-Makran transform zone and areas adjacent to the Saindak porphyry deposit and Taftan Volcano contain primarily phyllic-altered rocks that form linear patterns associated with extensive faulting and fractures indicative of epithermal and (or) polymetallic vein deposits.</p>\n<p>&nbsp;</p>\n<p>The ASTER alteration map and corresponding geologic maps were used to select circular to elliptical patterns of argillic- and phyllic-altered volcanic and intrusive rocks as potential porphyry copper sites. One hundred and seventy eight potential porphyry copper sites were mapped along the UDVB, and 23 sites were mapped along the CVB. The potential sites were selected to assist in further exploration and assessments of undiscovered porphyry copper deposits.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Global

S. Virgin Islands: an annotated checklist","docAbstract":"An historical account is given for the ichthyological research at St. Croix, U. S. Virgin Islands, followed by an annotated list of 544 species of mostly marine shore fishes known or reported from the island to depths of 200 m. Color photographs are included for 103 of these species. Collections made at Buck Island Reef National Monument with the ichthyocide rotenone in 2001 and 2005 increased the known ichthyofauna by about 80 species. The rational for inclusion of each species in the checklist is given, with remarks for those species for which additional documentation or voucher specimens are needed. Reports of species known or presumed to have been based on misidentifications are discussed. Of the total marine fish fauna of the island, 404 species (75%) are restricted to the western Atlantic Ocean, (223 of these species are essentially Caribbean endemics that do not occur south of the Amazon River outflow), and no St. Croix endemic species are known. An additional 17 species (3.2%) also occur at mid-Atlantic islands, 57 species (10.6 %) are limited to both sides of the Atlantic Ocean, and 40 species (7.4%) have circumtropical distributions. The four most species-rich families are the Gobiidae (47 species), Serranidae (groupers and sea basses, 41), Labridae (wrasses and parrotfishes, 31), and Labrisomidae (scaly blennies, 27). Literature reports of Mosquitofish, <i>Gambusia</i> sp., from St. Croix apparently were based on misidentifications of a different introduced poeciliid genus. Four species of the amphidromus goby genus <i>Sicydium</i> occur in St. Croix inland waters, together with three established introduced species (one cichlid and two poeciliids). Also included are one catfish (Ictaluridae) and three sunfishes (Centrarchidae) known only from ponds. The Lionfish, <i>Pterois volitans</i>, the only introduced marine species, was first reported from St. Croix in 2008 and is now common despite control efforts.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Zootaxa","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Magnolia Press","publisherLocation":"Auckland, New Zealand","doi":"10.11646/zootaxa.3803.1.1","usgsCitation":"Smith-Vaniz, W., and Jelks, H.L., 2014, Marine and inland fishes of St. Croix, U.

We used a sensitive high-resolution ion microprobe (SHRIMP) to date nine samples of Neoproterozoic rock and five samples of Devonian rock from the Brooks Range and Seward Peninsula of Alaska and from the Chukotka Peninsula of northeastern Russia. Felsic magmatism occurred at 968 Ma and 742 Ma in the Brooks Range and at 865 Ma and 670–666 Ma on Seward Peninsula. Felsic igneous rocks in Chukotka were dated at 656 Ma and 574 Ma. Devonian igneous rocks are found throughout the Arctic Alaska–Chukotka terrane, and we dated samples with ages of 391 Ma, 390 Ma, 385 Ma, 371 Ma, and 363 Ma. The felsic character of the Neoproterozoic rocks suggests formation at least in part through crustal melting. The age of the crustal source rocks that melted to form the Neoproterozoic rocks is inferred to be Mesoproterozoic based on Nd model ages ranging from 1.6 to 1.4 Ga. Rocks of this age range have been reported from the basement of Baltica but are rare in Laurentia. The 565 Ma orthogneisses on Seward Peninsula have ca. 1.1 Ga Nd model ages. Devonian igneous rocks have a wide range of model ages ranging from 1.6 to 0.8 Ga. The tectonic setting of the 968 Ma, 865 Ma, and 742 Ma rocks is unknown. The ca. 670 Ma magmatism on Seward Peninsula is interpreted to have occurred in an arc setting based on geochemistry and similarities in their ages to the Avalonian–Cadomian arc system peripheral to Gondwana. Latest Neoproterozoic magmatism is inferred to have occurred in a rift setting based on composition and the Paleozoic passive margin sequence that was deposited across the Arctic Alaska–Chukokta terrane. Devonian magmatism likely occurred in an arc and/or backarc rift setting. Significant uncertainties remain concerning the age of the Arctic Alaska–Chukotka terrane basement, particularly the age of the host rocks for Neoproterozoic intrusions.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Reconstruction of a Late Proterozoic to Devonian continental margin sequence, northern Alaska, its paleogeographic

However, methane-formation temperatures in nature are often poorly constrained. We measured formation temperatures of thermogenic and biogenic methane using a “clumped isotope” technique. Thermogenic gases yield formation temperatures between 157° and 221°C, within the nominal gas window, and biogenic gases yield formation temperatures consistent with their comparatively lower-temperature formational environments (<50°C). In systems where gases have migrated and other proxies for gas-generation temperature yield ambiguous results, methane clumped-isotope temperatures distinguish among and allow for independent tests of possible gas-formation models.","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.1254509","usgsCitation":"Stolper, D., Lawson, M., Davis, C., Ferreira, A., Santos Neto, E.V., Ellis, G., Lewan, M.D., Martini, A.M., Tang, Y., Schoell, M., Sessions, A., and Eiler, J., 2014, Formation temperatures of thermogenic and biogenic methane: Science, v. 344, no. 6191, p. 1500-1503, https://doi.org/10.1126/science.1254509.","productDescription":"4 p.","startPage":"1500","endPage":"1503","numberOfPages":"4","ipdsId":"IP-056199","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":472907,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20140604-103128643","text":"External Repository"},{"id":289298,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"344","issue":"6191","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b3ca53e4b07c5f79a7f313","contributors":{"authors":[{"text":"Stolper, D.A.","contributorId":12782,"corporation":false,"usgs":true,"family":"Stolper","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":495530,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lawson, M.","contributorId":15932,"corporation":false,"usgs":true,"family":"Lawson","given":"M.","email":"","affiliations":[],"preferred":false,"id":495531,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Davis, C.L.","contributorId":79024,"corporation":false,"usgs":true,"family":"Davis","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":495538,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ferreira, A.A.","contributorId":18273,"corporation":false,"usgs":true,"family":"Ferreira","given":"A.A.","email":"","affiliations":[],"preferred":false,"id":495532,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Santos Neto, E.

However, safely managing visitors during traffic jams that result from this activity often requires the use of limited park resources. Using unique visitor survey data, this study quantifies economic values associated with roadside bear viewing in Yellowstone National Park, monetary values that could be used to determine whether this continued use of park resources is warranted on economic grounds. Based on visitor expenditure data and results of a contingent visitation question, it is estimated that summer Park visitation would decrease if bears were no longer allowed to stay along roadside habitats, resulting in a loss of 155 jobs in the local economy. Results from a nonmarket valuation survey question indicate that on average, visitors to Yellowstone National Park are willing to pay around $41 more in Park entrance fees to ensure that bears are allowed to remain along roads within the Park. Generalizing this value to the relevant population of visitors indicates that the economic benefits of allowing this wildlife viewing opportunity to continue could outweigh the costs of using additional resources to effectively manage these traffic jams.</span></p>","language":"English","publisher":"Elsevier","publisherLocation":"Oxford,

Detrital zircon populations from metamorphosed rift-related mafic volcaniclastic rocks, a lithologic subunit of the Nome Complex, contain a dominant population of 740–550 Ma zircons. Samples from three other lithologic units yielded populations dominated by early Paleozoic zircons and characterized by a large population of 450–420 Ma zircons. A few samples, taken from two different lithologic units, yielded populations dominated by Mesoproterozoic zircons (most around 1.25–0.9 Ga) and lacked zircons younger than 900 Ma.

A second, highly divergent lentiviral clade, PLVA, infects mountain lions in southern California and Florida. Bobcats (<i>Lynx rufus</i>) in these two geographic regions are also infected with PLVA, and to date, this is the only strain of lentivirus identified in bobcats. We sequenced full-length PLV genomes in order to characterize the molecular evolution of PLV in bobcats and mountain lions. Low sequence homology (88% average pairwise identity) and frequent recombination (1 recombination breakpoint per 3 isolates analyzed) were observed in both clades. Viral proteins have markedly different patterns of evolution; sequence homology and negative selection were highest in Gag and Pol and lowest in Vif and Env. A total of 1.7% of sites across the PLV genome evolve under positive selection, indicating that host-imposed selection pressure is an important force shaping PLV evolution. PLVA strains are highly spatially structured, reflecting the population dynamics of their primary host, the bobcat. In contrast, the phylogeography of PLVB reflects the highly mobile mountain lion, with diverse PLVB isolates cocirculating in some areas and genetically related viruses being present in populations separated by thousands of kilometers. We conclude that PLVA and PLVB are two different viral species with distinct feline hosts and evolutionary histories.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Virology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Society for Microbiology","doi":"10.1128/JVI.00473-14","usgsCitation":"Lee, J., Bevins, S.N., Serieys, L., Vickers, W., Logan, K.A., Aldredge, M., Boydston, E.E., Lyren, L.M., McBride, R., Roelke-Parker, M., Pecon-Slattery, J., Troyer, J.L., Riley, S.P., Boyce, W.M., Crooks, K.R., and VandeWoude, S., 2014, Evolution of puma lentivirus in bobcats (<i>Lynx rufus</i>) and mountain lions (<i>Puma concolor</i>) in North America: Journal of Virology, v. 88, no. 14, p. 7727-7737, https://doi.org/10.1128/JVI.00473-14.","productDescription":"11 p.","startPage":"7727","endPage":"7737","numberOfPages":"11","ipdsId":"IP-053406","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":472908,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1128/jvi.00473-14","text":"Publisher Index Page"},{"id":289294,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":289272,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1128/JVI.00473-14"}],"country":"United States","otherGeospatial":"North America","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.8,24.5 ], [ -124.8,49.383333 ], [ -66.95,49.383333 ], [ -66.95,24.5 ], [ -124.8,24.5 ] ] ] } } ] }","volume":"88","issue":"14","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b3ca53e4b07c5f79a7f311","contributors":{"authors":[{"text":"Lee, Justin S.","contributorId":44014,"corporation":false,"usgs":true,"family":"Lee","given":"Justin S.","affiliations":[],"preferred":false,"id":495480,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bevins, Sarah N.","contributorId":105571,"corporation":false,"usgs":true,"family":"Bevins","given":"Sarah","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":495491,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Serieys, Laurel E.K.","contributorId":86695,"corporation":false,"usgs":false,"family":"Serieys","given":"Laurel E.K.","affiliations":[{"id":7081,"text":"University of California -

Advancements include solid-state excitation sources, integration of fiber optic technology, highly sensitive multichannel detectors, rapid-scan monochromators, sensitive spectral correction techniques, and improve data manipulation software (Christian et al., 1981, Lochmuller and Saavedra, 1986; Cabniss and Shuman, 1987; Lakowicz, 2006; Hudson et al., 2007). The cumulative effect of these improvements have pushed the limits and expanded the application of fluorescence techniques to numerous scientific research fields. One of the more powerful advancements is the ability to obtain in situ fluorescence measurements of natural waters (Moore, 1994).</p>\n<br>\n<p>The development of submersible fluorescence instruments has been made possible by component miniaturization and power reduction including advances in light sources technologies (light-emitting diodes, xenon lamps, ultraviolet [UV] lasers) and the compatible integration of new optical instruments with various sampling platforms (Twardowski et at., 2005 and references therein). The development of robust field sensors skirt the need for cumbersome and or time-consuming filtration techniques, the potential artifacts associated with sample storage, and coarse sampling designs by increasing spatiotemporal resolution (Chen, 1999; Robinson and Glenn, 1999). The ability to obtain rapid, high-quality, highly sensitive measurements over steep gradients has revolutionized investigations of dissolved organic matter (DOM) optical properties, thereby enabling researchers to address novel biogeochemical questions regarding colored or chromophoric DOM (CDOM).</p>\n<br>\n<p>This chapter is dedicated to the origin, design, calibration, and use of in situ field fluorometers. It will serve as a review of considerations to be accounted for during the operation of fluorescence field sensors and call attention to areas of concern when making this type of measurement. Attention is also given to ways in which in-water fluorescence measurements have revolutionized biogeochemical studies of CDOM and how those measurements can be used in conjunction with remotely sense satellite data to understand better the biogeochemistry of DOM in aquatic environments.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Aquatic organic matter fluorescence","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Cambridge University Press","publisherLocation":"New York, NY","isbn":"9780521764612","usgsCitation":"Conmy, R.N., Del Castillo, C.E., Downing, B.D., and Chen, R.F., 2014, Experimental design and quality assurance: in situ fluorescence instrumentation, chap. <i>of</i> Aquatic organic matter fluorescence, p. 190-233.","productDescription":"44 p.","startPage":"190","endPage":"233","numberOfPages":"44","ipdsId":"IP-029501","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":294765,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"542e6954e4b092f17df5a837","contributors":{"authors":[{"text":"Conmy, Robyn N.","contributorId":98657,"corporation":false,"usgs":true,"family":"Conmy","given":"Robyn","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":497150,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Del Castillo, Carlos E.","contributorId":76238,"corporation":false,"usgs":true,"family":"Del Castillo","given":"Carlos","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":497149,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Downing, Bryan D. 0000-0002-2007-5304 bdowning@usgs.gov","orcid":"https://orcid.org/0000-0002-2007-5304","contributorId":1449,"corporation":false,"usgs":true,"family":"Downing","given":"Bryan","email":"bdowning@usgs.gov","middleInitial":"D.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":497147,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Chen, Robert F.","contributorId":70707,"corporation":false,"usgs":true,"family":"Chen","given":"Robert","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":497148,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The original (1988) manual merged and expanded on ideas and recommendations related to Upper Mississippi River fish sampling presented in several early documents. The first revision to the manual was made in 1995 reflecting important protocol changes, such as the adoption of a stratified random sampling design. The 1995 procedures manual has been an important document through the years and has been cited in many reports and scientific manuscripts. The resulting data collected by the LTRMP fish component represent the largest dataset on fish within the Upper Mississippi River System (UMRS) with more than 44,000 collections of approximately 5.7 million fish.</p>\n<br>\n<p>The goal of this revision of the procedures manual is to document changes in LTRMP fish sampling procedures since 1995. Refinements to sampling methods become necessary as monitoring programs mature.

Nome Complex provides key information for understanding deposit genesis and crustal evolution. A total of 106 new analyses of galena (and other sulfi des) and metasedimentary rocks hosting the deposits shows that (1) Pb isotope signatures of the deposits are heterogeneous when considered as a group; (2) the stratabound Nelson deposit, and deformed veins at Quarry and Galena, are isotopically similar; (3) stratabound and locally stratiform lenses such as Wheeler North and Aurora Creek had different isotopic evolutions; and (4) the occurrence at Bluff and the postmetamorphic, undeformed Pb-Zn-Ag veins and replacements at Hannum, Independence, Foster, and Omilak show the highest values of<span>&nbsp;</span><sup>206</sup>Pb/<sup>204</sup>Pb in the region. Pb isotope data for the stratabound Zn-Pb deposits and occurrences do not lie along similar secondary or anomalous lead evolution lines, and there is no shared, two-stage lead line that would provide intersections with a primary or single-stage lead isotope growth curve.</p><p>Lead isotopic characteristics of the Nelson stratabound deposit and the deformed veins at Quarry and Galena indicate that they largely shared metal and fluid sources. Quarry and Galena also display sufficient Pb isotopic contrast compared to Aurora Creek and Wheeler North to eliminate such veins as subsurface “feeders” for these stratabound deposits, if the deformed veins and deposits formed as closed isotopic systems (without a contribution from externally derived lead). The Pb isotope composition of galena from Aurora Creek formed by a multistage process. It is thus possible that the Aurora Creek deposit originally contained Pb isotope compositions that resembled those from Quarry and Galena. That early-formed Pb was probably remobilized and mixed with radiogenic lead contributed by Mesozoic hydrothermal fluids similar to those associated with the gold-quartz veins in the region. Values of<span>&nbsp;</span><sup>207</sup>Pb/<sup>204</sup>Pb and<span>&nbsp;</span><sup>206</sup>Pb/<sup>204</sup>Pb from each of the deposits and occurrences plot within the Pb isotope fields of the host metasedimentary rocks and Mesoproterozoic basement rocks of Seward Peninsula; Pb isotope compositions in the deposits thus reflect a local source control.</p><p>The processes that generated the premetamorphic Zn-Pb(-Ag-Au-Ba-F) sulfide deposits in the Nome Complex differed from those that generated Zn-Pb-Ag deposits in the western Brooks Range, such as the giant Red Dog ore body. Taken as a group, the stratabound lenses and deformed veins in the Nome Complex did not form in a single, widespread, homogeneous hydrothermal system. The Brooks Range deposits, which consist of a range of host rock types and styles of mineralization distributed over a large area, have a high degree of regional Pb isotope homogeneity. The Wheeler North deposit is isotopically similar to Red Dog and related deposits and may have formed in a related hydrothermal system.</p><p>A preliminary comparison of the Pb isotope compositions of sedimentary-exhalative (SEDEX)–type deposits within the Arctic Alaska–Chukotka terrane and deposits in crustal blocks of Laurussia shows: (1) noteworthy Pb isotopic overlap exists between some of Zn-Pb-Ag deposits in Ireland and the deposits in Arctic Alaska ; but (2) no exact isotopic match exists between any of the deposits in Arctic Alaska and any deposit in crustal blocks involved in the Paleozoic evolution of Laurussia.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Reconstruction of a Late Proterozoic to Devonian continental margin sequence, northern Alaska, its paleogeographic significance, and contained base-metal sulfide deposits","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/2014.2506(07)","usgsCitation":"Ayuso, R.A., Till, A., Slack, J.F., and Forni, F., 2014, Pb isotope geochemistry of stratabound Zn-Pb(-Ag-Au-Ba-F) deposits and occurrences in the Nome Complex, Seward Peninsula, Alaska: Metal sources and regional comparisons, chap. <i>of</i> Reconstruction of a Late Proterozoic to Devonian continental margin sequence, northern Alaska, its paleogeographic significance, and contained base-metal sulfide deposits, v. 506, p. 213-234, https://doi.org/10.1130/2014.2506(07).","productDescription":"22 p.","startPage":"213","endPage":"234","ipdsId":"IP-054567","costCenters":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"links":[{"id":383162,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Seward Peninsula","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -168.255615234375,\n              64.09140752262307\n            ],\n            [\n              -160.916748046875,\n              64.09140752262307\n            ],\n            [\n              -160.916748046875,\n              66.83948674792073\n            ],\n            [\n              -168.255615234375,\n              66.83948674792073\n            ],\n            [\n              -168.255615234375,\n              64.09140752262307\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"506","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Ayuso, Robert A. 0000-0002-8496-9534 rayuso@usgs.gov","orcid":"https://orcid.org/0000-0002-8496-9534","contributorId":2654,"corporation":false,"usgs":true,"family":"Ayuso","given":"Robert","email":"rayuso@usgs.gov","middleInitial":"A.","affiliations":[{"id":387,"text":"Mineral Resources Program","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":808730,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Till, Alison 0000-0002-6640-6877","orcid":"https://orcid.org/0000-0002-6640-6877","contributorId":247882,"corporation":false,"usgs":false,"family":"Till","given":"Alison","affiliations":[{"id":12545,"text":"USGS retired","active":true,"usgs":false}],"preferred":false,"id":808731,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Slack, John F. 0000-0001-6600-3130 jfslack@usgs.gov","orcid":"https://orcid.org/0000-0001-6600-3130","contributorId":1032,"corporation":false,"usgs":true,"family":"Slack","given":"John","email":"jfslack@usgs.gov","middleInitial":"F.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":387,"text":"Mineral Resources Program","active":true,"usgs":true}],"preferred":true,"id":808732,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Forni, Francesca","contributorId":248277,"corporation":false,"usgs":false,"family":"Forni","given":"Francesca","affiliations":[],"preferred":false,"id":808733,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Of the 69 crane night roosts we identified, 35 were flooded cropland sites and 34 were wetland\nsites. We found that both larger individual roost sites and larger complexes of roost sites supported larger peak numbers of\ncranes. Water depth used by roosting cranes averaged 10 cm (range 3-21 cm, mode 7 cm) and was similar between subspecies.\nWe found that cranes avoided sites that were regularly hunted or had high densities of hunting blinds. We suggest that managers\ncould decide on the size of roost sites to provide for a given crane population objective using a ratio of 1.5 cranes/ha. The fact\nthat cranes readily use undisturbed flooded cropland sites makes this a viable option for creation of roost habitat. Because\nhunting disturbance can limit crane use of roost sites we suggest these 2 uses should not be considered readily compatible.\nHowever, if the management objective of an area includes waterfowl hunting, limiting hunting to low blind densities and\nrestricting hunting to early morning may be viable options for creating a crane-compatible waterfowl hunt program.</p>","largerWorkTitle":"Proceedings of the North American Crane Workshop","conferenceTitle":"13<sup>th</sup> North American Crane Workshop","conferenceDate":"2014-04-14T00:00:00","conferenceLocation":"Lafayette, LA","language":"English","publisher":"North American Crane Working Group","publisherLocation":"Grand Island, NE","usgsCitation":"Ivey, G.L., Dugger, B., Herziger, C.P., Casazza, M.L., and Fleskes, J.P., 2014, Characteristics of sandhill crane roosts in the Sacramento-San Joaquin delta of California, p. 12-19.","productDescription":"p. 12-19","numberOfPages":"8","ipdsId":"IP-053268","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":289361,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Sacramento-San Joaquin Delta","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.840793,38.014798 ], [ -121.840793,38.108875 ], [ -121.501076,38.108875 ], [ -121.501076,38.014798 ], [ -121.840793,38.014798 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b7b0cae4b0388651d91672","contributors":{"authors":[{"text":"Ivey, Gary L.","contributorId":79802,"corporation":false,"usgs":true,"family":"Ivey","given":"Gary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":492957,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dugger, Bruce D.","contributorId":81236,"corporation":false,"usgs":true,"family":"Dugger","given":"Bruce D.","affiliations":[],"preferred":false,"id":492958,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Herziger, Caroline P.","contributorId":23441,"corporation":false,"usgs":true,"family":"Herziger","given":"Caroline","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":492956,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Casazza, Michael L. 0000-0002-5636-735X mike_casazza@usgs.gov","orcid":"https://orcid.org/0000-0002-5636-735X","contributorId":2091,"corporation":false,"usgs":true,"family":"Casazza","given":"Michael","email":"mike_casazza@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":492955,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fleskes, Joseph P. 0000-0001-5388-6675 joe_fleskes@usgs.gov","orcid":"https://orcid.org/0000-0001-5388-6675","contributorId":1889,"corporation":false,"usgs":true,"family":"Fleskes","given":"Joseph","email":"joe_fleskes@usgs.gov","middleInitial":"P.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":492954,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Mississippian limestone units in the area (Tin Mountain, Stone Canyon, and Santa Rosa Hills Limestones) accumulated on the outer part of a broad carbonate platform that extended southwest across Nevada into east-central California. Carbonate sedimentation was interrupted by a major eustatic sea-level fall that has been interpreted to record the onset of late Paleozoic glaciation in southern Gondwana. Following a brief period of Late Mississippian clastic sedimentation (Indian Springs Formation), a rise in eustatic sea level led to establishment of a new carbonate platform that covered most of the area previously occupied by the Mississippian platform. The Pennsylvanian Bird Spring Formation at Marble Canyon makes up the outer platform component of ten third-order (1 to 5 m.y. duration) stratigraphic sequences recently defined for the regional platform succession.</p>\n<br/>\n<p>The regional paleogeography was fundamentally changed by major tectonic activity along the continental margin beginning in middle early Permian time. As a result, the Pennsylvanian carbonate shelf at Marble Canyon subsided and was disconformably overlain by lower Permian units (Osborne Canyon and Darwin Canyon Formations) representing part of a deep-water turbidite basin filled primarily by fine-grained siliciclastic sediment derived from cratonal sources to the east. Deformation and sedimentation along the western part of this basin continued into late Permian time.

We employed multivariate spatial regression techniques to estimate how difference factors affect median home values in 613 census block groups of the 2000 Census, accounting for spatial autocorrelation, spatial lags, and/or spatial heterogeneity in the data.  Diagnostic tests suggest that failure to account for the hedonic model can be classified as (1) physical features of the housing stock, (2) neighborhood characteristics, and (3) environmental attributes.  Census data was combined with GIS data for vegetation and land cover, land administration, measures of species richness and open space, and proximity to amenities and disamenities.  Census block groups close to the US-Mexico border of airports/air bases were negative.  Results suggest that policies to maintain biodiversity and open space provide economic benefits to homeowners, reflected in higher home values.  Future research will quantify the marginal effects of regression explanatory variables on home values to assess their economic and policy significant.  These marginal effects will be used as input indicators to discern potential economic impacts of various scenarios in the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM).  Future research will also expand this effort into the Mexican-portion of the watershed.</p>","largerWorkTitle":"Santa Cruz River Researchers� Day 2012","conferenceTitle":"Santa Cruz River Researchers' Day 2012 - <i>4th Annual</i>","conferenceDate":"2012-03-29T00:00:00","conferenceLocation":"Tucson, AZ","language":"English","publisher":"The Sonoran Institute","publisherLocation":"Tucson, AZ","usgsCitation":"Arora, G., Frisvold, G., and Norman, L., 2014, Effects of environmental amenities and locational disamenities on home values in the Santa Cruz watershed: a hedonic analysis using census data, 18 p.","productDescription":"18 p.","numberOfPages":"18","ipdsId":"IP-039103","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":289426,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","county":"Santa Cruz County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.36689,31.332177 ], [ -111.36689,31.731819 ], [ -110.45172,31.731819 ], [ -110.45172,31.332177 ], [ -111.36689,31.332177 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b67b6ee4b014fc094d5462","contributors":{"authors":[{"text":"Arora, Gaurav","contributorId":81020,"corporation":false,"usgs":true,"family":"Arora","given":"Gaurav","email":"","affiliations":[],"preferred":false,"id":492574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Frisvold, George","contributorId":9569,"corporation":false,"usgs":true,"family":"Frisvold","given":"George","email":"","affiliations":[],"preferred":false,"id":492573,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Norman, Laura","contributorId":90382,"corporation":false,"usgs":true,"family":"Norman","given":"Laura","affiliations":[],"preferred":false,"id":492575,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We examined how the conservation community has responded to these challenges and how the responses have changed over time, using twenty years of abstracts from the Hawaiʻi Conservation Conference, a yearly gathering of the majority of scientists, managers and the public in Hawaiʻi. Of the 2145 abstracts considered, 60% percent reported research results; 40.0% reported information on conservation and resource management programmes and institutions (i.e., non-research abstracts). Initially, applied research abstracts predominated, but in recent years the number of basic research abstracts has become similar. Across taxonomic groups, terrestrial plants, mammals and birds were the dominant research subjects, fish, algae and fungi were noticeably less studied relative to their diversity in Hawaiʻi. Bird and fish species studied were mostly native; research on most other taxa was evenly divided between native and non-native species. Topics have oscillated in frequency over the years, but there have been no dramatic trends, with the exception of climate change and Local Ecological Knowledge (LEK). Although there is an increasing trend in LEK and cross-disciplinary studies, the number of related abstracts have remained uncommon through the period, accounting for less than 5.0% of total research abstracts analyzed. Our results offer an oportunity for the conservation community to take a closer look at reported effort to better address key conservation questions for Hawaiʻi.</span></p>","language":"English","publisher":"CSIRO Publishing","doi":"10.1071/PC140392","usgsCitation":"Dutra Elliott, D., Fortini, L.B., and Duffy, D.C., 2014, Trends in conservation
