Many are large, deep slides in sedimentary rock and are dormant or active only during the rainy season. Morphology, observed movement rates, and total movement suggest that many are at least several hundreds of years old. The offshore Cascadia subduction zone produces great earthquakes every 300–500 years that generate tsunami that inundate the coast within minutes. Many slides and slide-prone areas underlie tsunami evacuation and emergency response routes. We evaluated the likelihood of existing and future large rockslides being triggered by pore-water pressure increase or earthquake-induced ground motion using field observations and modeling of three typical slides. Monitoring for 2–9 years indicated that the rockslides reactivate when pore pressures exceed readily identifiable levels. Measurements of total movement and observed movement rates suggest that two of the rockslides are 296–336 years old (the third could not be dated). The most recent great Cascadia earthquake was M 9.0 and occurred during January 1700, while regional climatological conditions have been stable for at least the past 600 years. Hence, the estimated ages of the slides support earthquake ground motion as their triggering mechanism. Limit-equilibrium slope-stability modeling suggests that increased pore-water pressures could not trigger formation of the observed slides, even when accompanied by progressive strength loss. Modeling suggests that ground accelerations comparable to those recorded at geologically similar sites during the M 9.0, 11 March 2011 Japan Trench subduction-zone earthquake would trigger formation of the rockslides. Displacement modeling following the Newmark approach suggests that the rockslides would move only centimeters upon coseismic formation; however, coseismic reactivation of existing rockslides would involve meters of displacement. Our findings provide better understanding of the dynamic coastal bluff environment and hazards from future subduction-zone earthquakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geomorphology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.geomorph.2011.12.026","issn":"0169555X","usgsCitation":"Schulz, W., Galloway, S., and Higgins, J., 2012, Evidence for earthquake triggering of large landslides in coastal Oregon, USA: Geomorphology, v. 141-142, p. 88-98, https://doi.org/10.1016/j.geomorph.2011.12.026.","productDescription":"11 p.","startPage":"88","endPage":"98","costCenters":[],"links":[{"id":213971,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2011.12.026"},{"id":241649,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.61,42.0 ], [ -124.61,46.29 ], [ -116.46,46.29 ], [ -116.46,42.0 ], [ -124.61,42.0 ] ] ] } } ] }","volume":"141-142","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d3de4b0c8380cd52ec6","contributors":{"authors":[{"text":"Schulz, W.H.","contributorId":61225,"corporation":false,"usgs":true,"family":"Schulz","given":"W.H.","email":"","affiliations":[],"preferred":false,"id":436472,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Galloway, S.L.","contributorId":107945,"corporation":false,"usgs":true,"family":"Galloway","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":436473,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Higgins, J.D.","contributorId":37154,"corporation":false,"usgs":true,"family":"Higgins","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":436471,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In the Ipswich River, Massachusetts, measuring habitat units and physical conditions at transects (width, depth, and velocity) provided an ecological basis for the interpretation of landscape patterns of fish distribution. Mapping habitat units allowed us to efficiently census habitat relevant to alewives for the entire 20.6 river kilometers of interest. Our transect data reinforced the results of the habitat unit survey and provided useful, high‐resolution ecological data for restoration efforts. Tagged alewives spent little time in riffle–run habitats and substantial time in pools, although the locations of pool occupancy varied.

However, salinization can also occur from the capillary rise of salts from the aquifer into the vadose zone. We investigated the roles of saltcedar and physical factors in salinizing the soil profile of a non-flooding terrace at sites on the Cibola National Wildlife Refuge on the Lower Colorado River, USA. We placed salt traps under and between saltcedar shrubs and estimated the annual deposition rate of salts from saltcedar. These were then compared to the quantities and distribution on of salts in the soil profile. Dense stands of saltcedar deposited 0.159&nbsp;kg&nbsp;m</span><sup>−2</sup><span>&nbsp;yr</span><sup>−1</sup><span>&nbsp;of salts to the soil surface.

Eliminating saltcedar would not necessarily reduce salts, because vegetation reduces the upward migration of salts in bulk flow from the aquifer.

LPAIv may persist for extended periods in cold environments, suggesting that waterfowl breeding areas in the northern hemisphere may be an important reservoir for AIv in contrast to the warmer southern wintering areas. We evaluated whether southern wetlands, with relatively small populations (thousands) of resident waterfowl, maintain AIv in the summer, prior to the arrival of millions of migratory birds. We collected water and fecal samples at ten wetlands in two regions (Yolo Bypass and Sacramento Valley) of the California Central Valley during three bi-weekly intervals beginning in late July, 2010. We detected AIv in 29/367 fecal samples (7.9%) and 12/597 water samples (2.0%) by matrix real time Reverse Transcription Polymerase Chain Reaction (rRT-PCR). We isolated two H3N8, two H2N3, and one H4N8 among rRT-PCR positive fecal samples but no live virus from water samples. Detection of AIv RNA in fecal samples was higher from wetlands in the Sacramento Valley (11.9%) than in the Yolo Bypass (0.0%), but no difference was found for water samples (2.7 vs. 1.7%, respectively). Our study showed that low densities of hosts and unfavorable environmental conditions did not prevent LPAIv circulation during summer in California wetlands. Our findings justify further investigations to understand AIv dynamics in resident waterfowl populations, compare AIv subtypes between migratory and resident waterfowl, and assess the importance of local AIv as a source of infection for migratory birds.</span></p>","language":"English","publisher":"PLOS","doi":"10.1371/journal.pone.0031471","usgsCitation":"Henaux, V., Samuel, M., Dusek, R.,

We studied the current state and potential causes of fragmentation in grizzly bears over approximately 1,000,000 km  2 of western Canada, the northern United States (US), and southeast Alaska. We compiled much of our data from projects undertaken with a variety of research objectives including population estimation and trend, landscape fragmentation, habitat selection, vital rates, and response to human development. Our primary analytical techniques stemmed from genetic analysis of 3,134 bears, supplemented with radiotelemetry data from 792 bears. We used 15 locus microsatellite data coupled withmeasures of genetic distance, isolation-by-distance (IBD) analysis, analysis of covariance (ANCOVA), linear multiple regression, multi-factorial correspondence analysis (to identify population divisions or fractures with no a priori assumption of group membership), and population-assignment methods to detect individual migrants between immediately adjacent areas. These data corroborated observations of inter-area movements from our telemetry database. In northern areas, we found a spatial genetic pattern of IBD, although there was evidence of natural fragmentation from the rugged heavily glaciated coast mountains of British Columbia (BC) and the Yukon. These results contrasted with the spatial pattern of fragmentation in more southern parts of their distribution. Near the Canada-US border area, we found extensive fragmentation that corresponded to settled mountain valleys andmajor highways. Genetic distances across developed valleys were elevated relative to those across undeveloped valleys in central and northern BC. In disturbed areas, most inter-area movements detected were made by male bears, with few female migrants identified. North-south movements within mountain ranges (Mts) and across BC Highway 3 were more common than east-west movements across settled mountain valleys separating Mts. Our results suggest that relatively distinct subpopulations exist in this region, including the Cabinet, Selkirk South, and the decadesisolated Yellowstone populations. Current movement rates do not appear sufficient to consider the subpopulations we identify along the Canada-US border as 1 inter-breeding unit. Although we detected enough male movement to mediate gene flow, the current low rate of female movement detected among areas is insufficient to provide a demographic rescue effect between areas in the immediate future (0-15 yr). In Alberta, we found fragmentation corresponded to major east-west highways (Highways 3, 11, 16, and 43) and most inter-area movements were made by males. Gene flow and movement rates between Alberta and BC were highest across the Continental Divide south of Highway 1 and north of Highway 16. In the central region between Highways 1 and 11, we found evidence of natural fragmentation associated with the extensive glaciers and icefields along the Continental Divide. The discontinuities that we identified would form appropriate boundaries formanagement units. We related sex-specific movement rates between adjacent areas to several metrics of human use (highway traffic, settlement, and humancaused mortality) to understand the causes of fragmentation. This analysis used data from 1,508 bears sampled over a 161,500-km  2 area in southeastern BC, western Alberta, northern Idaho, and northern Montana during 1979-2007. This area was bisected by numerous human transportation and settlement corridors of varying intensity and complexity. We used multiple linear regression and ANCOVA to document the responses of female and male bears to disturbance. Males and females both demonstrated reduced movement rates with increasing settlement and traffic. However, females reduced their movement rates dramatically when settlement increased to &gt;20% of the fracture zone.

In birds, although several species (including the black-legged kittiwake) exhibit non-random mating according to genetic traits, the cues used to assess genetic characteristics remain unknown. The importance of olfaction in birds' social behaviour is gaining attention among researchers, and it has been suggested that, as in other vertebrates, bird body scent may convey information about genetic traits. Here, we combined gas chromatography data and genetic analyses at microsatellite loci to test whether semiochemical messages in preen secretion of kittiwakes carried information about genetic heterozygosity and relatedness. Semiochemical profile was correlated with heterozygosity in males and females, while semiochemical distance was correlated with genetic distance only in male–male dyads. Our study is the first to demonstrate a link between odour and genetics in birds, which sets the stage for the existence of sophisticated odour-based mechanisms of mate choice also in birds.</span></p>","language":"English","publisher":"The Royal Society","doi":"10.1098/rspb.2011.1611","usgsCitation":"Leclaire, S., Merkling, T., Raynaud, C., Mulard, H., Bessiere, J., Lhuillier, E., Hatch, S.A., and Danchin, E., 2012, Semiochemical compounds of preen secretion reflect genetic make-up in a seabird species: Proceedings of the Royal Society B: Biological Sciences, v. 279, no. 1731, p. 1185-1193, https://doi.org/10.1098/rspb.2011.1611.","productDescription":"9 p.","startPage":"1185","endPage":"1193","numberOfPages":"9","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":474627,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/3267147","text":"External Repository"},{"id":241243,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"279","issue":"1731","noUsgsAuthors":false,"publicationDate":"2011-09-21","publicationStatus":"PW","scienceBaseUri":"505b8d12e4b08c986b318256","contributors":{"authors":[{"text":"Leclaire, S.","contributorId":39591,"corporation":false,"usgs":true,"family":"Leclaire","given":"S.","email":"","affiliations":[],"preferred":false,"id":436021,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Merkling, T.","contributorId":26522,"corporation":false,"usgs":true,"family":"Merkling","given":"T.","affiliations":[],"preferred":false,"id":436020,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Raynaud, C.","contributorId":46313,"corporation":false,"usgs":true,"family":"Raynaud","given":"C.","email":"","affiliations":[],"preferred":false,"id":436022,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mulard, Herve","contributorId":104602,"corporation":false,"usgs":false,"family":"Mulard","given":"Herve","email":"","affiliations":[],"preferred":false,"id":436026,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bessiere, J.-M.","contributorId":107107,"corporation":false,"usgs":true,"family":"Bessiere","given":"J.-M.","email":"","affiliations":[],"preferred":false,"id":436027,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lhuillier, E.M.","contributorId":103880,"corporation":false,"usgs":true,"family":"Lhuillier","given":"E.M.","affiliations":[],"preferred":false,"id":436025,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hatch, Scott A. 0000-0002-0064-8187 shatch@usgs.gov","orcid":"https://orcid.org/0000-0002-0064-8187","contributorId":2625,"corporation":false,"usgs":true,"family":"Hatch","given":"Scott","email":"shatch@usgs.gov","middleInitial":"A.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":436023,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Danchin, E.","contributorId":89635,"corporation":false,"usgs":true,"family":"Danchin","given":"E.","affiliations":[],"preferred":false,"id":436024,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Creel and Rotella (2010) recently predicted substantial population declines in Montana wolf populations due to harvest, in contrast to predictions made by Montana Fish, Wildlife and Parks (MFWP). We replicated their analyses considering only those years in which field monitoring was consistent, and we considered the effect of annual variation in recruitment on wolf population growth. Rather than assuming constant rates, we used model selection methods to evaluate and incorporate models of factors driving recruitment and human-caused mortality rates in wolf populations in the Northern Rocky Mountains. Using data from 27 area-years of intensive wolf monitoring, we show that variation in both recruitment and human-caused mortality affect annual wolf population growth rates and that human-caused mortality rates have increased with the sizes of wolf populations. We document that recruitment rates have decreased over time, and we speculate that rates have decreased with increasing population sizes and/or that the ability of current field resources to document recruitment rates has recently become less successful as the number of wolves in the region has increased. Estimates of positive wolf population growth in Montana from our top models are consistent with field observations and estimates previously made by MFWP for 2008–2010, whereas the predictions for declining wolf populations of Creel and Rotella (2010) are not. Familiarity with limitations of raw data, obtained first-hand or through consultation with scientists who collected the data, helps generate more reliable inferences and conclusions in analyses of publicly available datasets. Additionally, development of efficient monitoring methods for wolves is a pressing need, so that analyses such as ours will be possible in future years when fewer resources will be available for monitoring.</p>","language":"English","publisher":"The Wildlife Society","doi":"10.1002/jwmg.201","issn":"0022541X","usgsCitation":"Gude, J., Mitchell, M., Russell, R.E., Sime, C., Bangs, E., Mech, L., and Ream, R., 2012, Wolf population dynamics in the U.S. Northern Rocky Mountains are affected by recruitment and human-caused mortality: Journal of Wildlife Management, v. 76, no. 1, p. 108-118, https://doi.org/10.1002/jwmg.201.","productDescription":"11 p.","startPage":"108","endPage":"118","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true},{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":241289,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213642,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jwmg.201"}],"country":"United States","state":"Idaho, Montana, Wyoming","otherGeospatial":"The NWMT, CIEPA, and GYEPA federal wolf recovery area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -109.2041015625,\n              45.042478050891546\n            ],\n            [\n              -109.57763671875,\n              46.042735653846506\n            ],\n            [\n              -112.60986328125,\n              45.98169518512228\n            ],\n            [\n              -113.44482421875,\n              45.30580259943578\n            ],\n            [\n              -112.939453125,\n              44.11914151643737\n            ],\n            [\n              -110.98388671874999,\n              43.929549935614595\n            ],\n            [\n              -108.984375,\n              44.18220395771566\n            ],\n            [\n              -109.2041015625,\n              45.042478050891546\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"76","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-08-03","publicationStatus":"PW","scienceBaseUri":"505bd187e4b08c986b32f497","contributors":{"authors":[{"text":"Gude, J.A.","contributorId":101092,"corporation":false,"usgs":true,"family":"Gude","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":437242,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mitchell, M.S.","contributorId":26724,"corporation":false,"usgs":true,"family":"Mitchell","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":437236,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Russell, Robin E. 0000-0001-8726-7303 rerussell@usgs.gov","orcid":"https://orcid.org/0000-0001-8726-7303","contributorId":3998,"corporation":false,"usgs":true,"family":"Russell","given":"Robin","email":"rerussell@usgs.gov","middleInitial":"E.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":437237,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sime, C.A.","contributorId":54413,"corporation":false,"usgs":true,"family":"Sime","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":437239,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bangs, E.E.","contributorId":49614,"corporation":false,"usgs":true,"family":"Bangs","given":"E.E.","email":"","affiliations":[],"preferred":false,"id":437238,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mech, L.D. 0000-0003-3944-7769","orcid":"https://orcid.org/0000-0003-3944-7769","contributorId":75466,"corporation":false,"usgs":false,"family":"Mech","given":"L.D.","email":"","affiliations":[],"preferred":false,"id":437240,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Ream, R.R.","contributorId":93154,"corporation":false,"usgs":true,"family":"Ream","given":"R.R.","email":"","affiliations":[],"preferred":false,"id":437241,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

We examined the phytomass and diversity of vascular plants along altitudinal gradients on the dry alpine rangelands of Ladakh, western Himalaya. We used generalized linear and generalized additive models to assess the relationship between these vegetation parameters and altitude. We found a hump-shaped relationship between aboveground phytomass and altitude. We suspect that this is engendered by low rainfall and trampling/excessive grazing at lower slopes by domestic livestock, and low temperature and low nutrient levels at higher slopes. We also found a unimodal relationship between plant species-richness and altitude at a single mountain as well as at the scale of entire Ladakh. The species-richness at the single mountain peaked between 5,000 and 5,200&nbsp;m, while it peaked between 3,500 and 4,000&nbsp;m at entire Ladakh level. Perhaps biotic factors such as grazing and precipitation are, respectively, important in generating this pattern at the single mountain and entire Ladakh.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s10265-011-0430-1","issn":"09189440","usgsCitation":"Namgail, T., Rawat, G., Mishra, C., Wieren, V., and Prins, H., 2012, Biomass and diversity of dry alpine plant communities along altitudinal gradients in the Himalayas: Journal of Plant Research, v. 125, no. 1, p. 93-101, https://doi.org/10.1007/s10265-011-0430-1.","productDescription":"9 p.","startPage":"93","endPage":"101","costCenters":[],"links":[{"id":474648,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s10265-011-0430-1","text":"Publisher Index Page"},{"id":241373,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213718,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10265-011-0430-1"}],"country":"India","otherGeospatial":"Ladakh region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              75.34423828125,\n              34.52466147177172\n            ],\n            [\n              76.552734375,\n              33.247875947924385\n            ],\n            [\n              77.34374999999999,\n              32.7503226078097\n            ],\n            [\n              77.67333984375,\n              32.91648534731439\n            ],\n            [\n              78.046875,\n              32.509761735919426\n            ],\n            [\n              78.486328125,\n              32.54681317351514\n            ],\n            [\n              79.2333984375,\n              32.287132632616384\n            ],\n            [\n              79.6728515625,\n              32.676372772089834\n            ],\n            [\n              78.85986328125,\n              33.88865750124075\n            ],\n            [\n              79.0850830078125,\n              34.30714385628804\n            ],\n            [\n              78.46435546875,\n              34.66935854524543\n            ],\n            [\n              78.11279296875,\n              35.22767235493586\n            ],\n            [\n              78.1787109375,\n              35.55010533588552\n            ],\n            [\n              76.7724609375,\n              35.764343479667176\n            ],\n            [\n              76.88232421875,\n              35.08395557927643\n            ],\n            [\n              76.3330078125,\n              34.867904962568716\n            ],\n            [\n              75.43212890625,\n              34.687427949314845\n            ],\n            [\n              75.34423828125,\n              34.52466147177172\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"125","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-06-03","publicationStatus":"PW","scienceBaseUri":"5059f18be4b0c8380cd4acba","contributors":{"authors":[{"text":"Namgail, Tsewang","contributorId":150756,"corporation":false,"usgs":false,"family":"Namgail","given":"Tsewang","email":"","affiliations":[{"id":18092,"text":"formerly with U.S. Geological Survey, Western Ecological Research Center","active":true,"usgs":false}],"preferred":false,"id":436057,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rawat, G.S.","contributorId":65290,"corporation":false,"usgs":true,"family":"Rawat","given":"G.S.","email":"","affiliations":[],"preferred":false,"id":436056,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mishra, C.","contributorId":7092,"corporation":false,"usgs":true,"family":"Mishra","given":"C.","email":"","affiliations":[],"preferred":false,"id":436054,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wieren, van","contributorId":29653,"corporation":false,"usgs":true,"family":"Wieren","given":"van","email":"","affiliations":[],"preferred":false,"id":436055,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Prins, H.H.T.","contributorId":79697,"corporation":false,"usgs":true,"family":"Prins","given":"H.H.T.","email":"","affiliations":[],"preferred":false,"id":436058,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Recently, however, high throughput sequencing (with or without prior enrichment for specific SSR loci) has been utilized to identify SSR loci. The direct “Seq-to-SSR” approach has an advantage over enrichment-based strategies in that it does not require&nbsp;</span><i>a priori</i><span>&nbsp;selection of particular motifs, or prior knowledge of genomic SSR content. It has been more expensive per SSR locus recovered, however, particularly for genomes with few SSR loci, such as bird genomes. The longer but relatively more expensive 454 reads have been preferred over less expensive Illumina reads. Here, we use Illumina paired-end sequence data to identify potentially amplifiable SSR loci (PALs) from a snake (the Burmese python,&nbsp;</span><i>Python molurus bivittatus</i><span>), and directly compare these results to those from 454 data. We also compare the python results to results from Illumina sequencing of two bird genomes (Gunnison Sage-grouse,&nbsp;</span><i>Centrocercus minimus</i><span>, and Clark's Nutcracker,&nbsp;</span><i>Nucifraga columbiana</i><span>), which have considerably fewer SSRs than the python. We show that direct Illumina Seq-to-SSR can identify and characterize thousands of potentially amplifiable SSR loci for as little as $10 per sample – a fraction of the cost of 454 sequencing.

In northwest California, it comprises a stack of west vergent thrust sheets: westernmost Eastern Belt outliers; Central Belt m&eacute;lange; Coastal Belt Yager terrane; Coastal Belt Coastal terrane; Coastal Belt King Range/False Cape terranes. We collected samples and determined P-T conditions of recrystallization for 88 medium-fine-grained metasandstones to assess their subduction-exhumation histories and assembly of the host allochthons. Feebly recrystallized Yager, Coastal, and King Range strata retain clear detrital features. Scattered neoblastic prehnite occurs in several Coastal terrane metasandstones; traces of possible pumpellyite are present in three Yager metaclastic rocks. Pumpellyite &plusmn; lawsonite &plusmn; aragonite-bearing Central Belt metasandstones are moderately deformed and reconstituted. Intensely contorted, thoroughly recrystallized Eastern Belt affinity quartzose metagraywackes contain lawsonite + jadeitic pyroxene &plusmn; aragonite &plusmn; glaucophane. We microprobed neoblastic phases in 23 rocks, documenting mineral parageneses that constrain the tectonic accretion and metamorphic P-T evolution of these sheets. Quasi-stable mineral assemblages typify Eastern Belt metasandstones, but mm-sized domains in the Central and Coastal belt rocks failed to achieve chemical equilibrium. Eastern Belt slabs rose from subduction depths approaching 25&ndash;30&nbsp;km, whereas structurally lower Central Belt m&eacute;langes returned from &sim;15&ndash;18&nbsp;km. Coastal Belt assemblages suggest burial depths less than 5&ndash;8&nbsp;km. Eastern and Central belt allochthons sequentially decoupled from the downgoing oceanic lithosphere and ascended into the accretionary margin; K-feldspar-rich Coastal Belt rocks were stranded along the continental edge without undergoing appreciable subduction, probably during Paleogene unroofing of the older, deeply subducted units of the Franciscan Complex in east-vergent crustal wedges.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/2011TC002987","issn":"02787407","usgsCitation":"Ernst, W., and McLaughlin, R.J., 2012, Mineral parageneses, regional architecture, and tectonic evolution of Franciscan metagraywackes, Cape Mendocino-Garberville-Covelo 30' x 60' quadrangles, northwest California: Tectonics, v. 31, no. 1, Article TC1001, https://doi.org/10.1029/2011TC002987.","productDescription":"Article TC1001","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-033454","costCenters":[{"id":309,"text":"Geology and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":241657,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213979,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011TC002987"}],"country":"United States","state":"California","otherGeospatial":"Cape Mendocino-Garberville-Covelo","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.53002929687499,\n              39.2407625100131\n            ],\n            [\n              -124.53002929687499,\n              40.455307212131494\n            ],\n            [\n              -122.76123046875,\n              40.455307212131494\n            ],\n            [\n              -122.76123046875,\n              39.2407625100131\n            ],\n            [\n              -124.53002929687499,\n              39.2407625100131\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"31","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-01-12","publicationStatus":"PW","scienceBaseUri":"505a57a1e4b0c8380cd6ddd0","contributors":{"authors":[{"text":"Ernst, W.

Quantifying and understanding hydrological responses to elevated ambient CO<sub>2</sub> and climate change is, therefore, critical for formulating adaptive strategies for an appropriate management of water resources. In this study, the Soil and Water Assessment Tool (SWAT) model was applied to assess the effects of increased CO<sub>2</sub> concentration and climate change in the Upper Mississippi River Basin (UMRB). The standard SWAT model was modified to represent more mechanistic vegetation type specific responses of stomatal conductance reduction and leaf area increase to elevated CO<sub>2</sub> based on physiological studies. For estimating the historical impacts of increased CO<sub>2</sub> in the recent past decades, the incremental (i.e., dynamic) rises of CO<sub>2</sub> concentration at a monthly time-scale were also introduced into the model. Our study results indicated that about 1–4% of the streamflow in the UMRB during 1986 through 2008 could be attributed to the elevated CO<sub>2</sub> concentration. In addition to evaluating a range of future climate sensitivity scenarios, the climate projections by four General Circulation Models (GCMs) under different greenhouse gas emission scenarios were used to predict the hydrological effects in the late twenty-first century (2071–2100). Our simulations demonstrated that the water yield would increase in spring and substantially decrease in summer, while soil moisture would rise in spring and decline in summer. Such an uneven distribution of water with higher variability compared to the baseline level (1961–1990) may cause an increased risk of both flooding and drought events in the basin.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Climatic Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10584-011-0087-8","issn":"01650009","usgsCitation":"Wu, Y., Liu, S., and Abdul-Aziz, O., 2012, Hydrological effects of the increased CO<sub>2</sub> and climate change in the Upper Mississippi River Basin using a modified SWAT: Climatic Change, v. 110, no. 3-4, p. 977-1003, https://doi.org/10.1007/s10584-011-0087-8.","productDescription":"27 p.","startPage":"977","endPage":"1003","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":241687,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214003,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10584-011-0087-8"}],"country":"United States","otherGeospatial":"Mississippi River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -104.0577,28.9254 ], [ -104.0577,49.38 ], [ -80.5182,49.38 ], [ -80.5182,28.9254 ], [ -104.0577,28.9254 ] ] ] } } ] }","volume":"110","issue":"3-4","noUsgsAuthors":false,"publicationDate":"2011-05-10","publicationStatus":"PW","scienceBaseUri":"505a36ace4b0c8380cd608e2","contributors":{"authors":[{"text":"Wu, Y.","contributorId":79312,"corporation":false,"usgs":true,"family":"Wu","given":"Y.","email":"","affiliations":[],"preferred":false,"id":436861,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, S.","contributorId":93170,"corporation":false,"usgs":true,"family":"Liu","given":"S.","affiliations":[],"preferred":false,"id":436863,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Abdul-Aziz, O.

The biotic/abiotic (A/B) interface separates seasonally reversible nutrient gradients, reflecting biological cycling in the shallower soils, from downward chemical weathering gradients in the deeper soils. The A/B interface is pedologically defined by argillic clay horizons centered at soil depths of about one meter which intensify with soil age. Below these horizons, elevated solute Na/Ca, Mg/Ca and Sr/Ca ratios reflect plagioclase and smectite weathering along pore water flow paths. Above the A/B interface, lower cation ratios denote temporal variability due to seasonal plant nutrient uptake and litter leaching. Potassium and Ca exhibit no seasonal variability beneath the A/B interface, indicating closed nutrient cycling within the root zone, whereas Mg variability below the A/B interface denotes downward leakage resulting from higher inputs of marine aerosols and lower plant nutrient requirements.</p><p id=\"sp010\">The fraction of a mineral nutrient annually cycled through the plants, compared to that lost from pore water discharge, is defined their respective fluxes<span>&nbsp;</span><i>F</i><sub>j,plants</sub>&nbsp;=&nbsp;<i>q</i><sub>j,plants</sub>/(<i>q</i><sub>j,plants</sub>&nbsp;+&nbsp;<i>q</i><sub>j,discharge</sub>) with average values for K and Ca (<i>F</i><sub>K,plants</sub>&nbsp;=&nbsp;0.99;<span>&nbsp;</span><i>F</i><sub>Ca,plants</sub>&nbsp;=&nbsp;0.93) much higher than for Mg and Na (<i>F</i><sub>Mg,plants</sub><span>&nbsp;</span>0.64;<span>&nbsp;</span><i>F</i><sub>Na,plants</sub>&nbsp;=&nbsp;0.28).

Of particular concern was the possibility that, under the anticipated high shut-in pressures, oil could leak out of the well casing below the seafloor. Such a leak could lead to new geologic pathways for hydrocarbon release to the Gulf of Mexico. Evaluating this hazard required analyses of 2D and 3D seismic surveys, seafloor bathymetry, sediment properties, geophysical well logs, and drilling data to assess the geological, hydrological, and geomechanical conditions around the Macondo Well. After the well was successfully capped and shut in on July 15, 2010, a variety of monitoring activities were used to assess subsurface well integrity. These activities included acquisition of wellhead pressure data, marine multichannel seismic profiles, seafloor and water-column sonar surveys, and wellhead visual/acoustic monitoring. These data showed that the Macondo Well was not leaking after shut in, and therefore, it could remain safely shut until reservoir pressures were suppressed (killed) with heavy drilling mud and the well was sealed with cement.</p>","language":"English","publisher":"National Academy of Sciences","doi":"10.1073/pnas.1115847109","usgsCitation":"Hickman, S.H., Hsieh, P.A., Mooney, W.D., Enomoto, C.B., Nelson, P.H., Weber, T.S., Mayer, L., Moran, K., Flemings, P., and McNutt, M.K., 2012, Scientific basis for safely shutting in the Macondo Well after the April 20, 2010 Deepwater Horizon blowout : PNAS, v. 109, no. 50, p. 20268-20273, https://doi.org/10.1073/pnas.1115847109.","productDescription":"6 p.","startPage":"20268","endPage":"20273","ipdsId":"IP-036940","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":490048,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1073/pnas.1115847109","text":"Publisher Index Page"},{"id":347348,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Gulf of Mexico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -98.349609375,\n              22.350075806124867\n            ],\n            [\n              -81.5625,\n              22.350075806124867\n            ],\n            [\n              -81.5625,\n              31.353636941500987\n            ],\n            [\n              -98.349609375,\n              31.353636941500987\n            ],\n            [\n              -98.349609375,\n              22.350075806124867\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"109","issue":"50","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2012-12-03","publicationStatus":"PW","scienceBaseUri":"59f1a2aae4b0220bbd9d9fd4","contributors":{"editors":[{"text":"Rice, James R.","contributorId":62601,"corporation":false,"usgs":false,"family":"Rice","given":"James","email":"","middleInitial":"R.","affiliations":[{"id":16811,"text":"Harvard University","active":true,"usgs":false}],"preferred":false,"id":715630,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Hickman, Stephen H. 0000-0003-2075-9615 hickman@usgs.gov","orcid":"https://orcid.org/0000-0003-2075-9615","contributorId":2705,"corporation":false,"usgs":true,"family":"Hickman","given":"Stephen","email":"hickman@usgs.gov","middleInitial":"H.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":715357,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hsieh, Paul A. 0000-0003-4873-4874 pahsieh@usgs.gov","orcid":"https://orcid.org/0000-0003-4873-4874","contributorId":1634,"corporation":false,"usgs":true,"family":"Hsieh","given":"Paul","email":"pahsieh@usgs.gov","middleInitial":"A.","affiliations":[{"id":37277,"text":"WMA -

These results can then be related to a given earthquake based on its seismic moment and the maximum slip within its rupture zone, assuming that the rupture process entails the same physics as stick-slip friction. This analysis yields overshoots and ratios of apparent stress to static stress drop of about 0.25. The inferred earthquake source parameters static stress drop, apparent stress, slip rate, and radiated energy are robust inasmuch as they are largely independent of the experimental parameters used in their estimation. Instead, these earthquake parameters depend on C, the ratio of maximum slip to the cube root of the seismic moment. C is controlled by the normal stress applied to the rupture plane and the difference between the static and dynamic coefficients of friction. Estimating yield stress and seismic efficiency using the same procedure is only possible when the actual static and dynamic coefficients of friction are known within the earthquake rupture zone.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/2011GL050327","usgsCitation":"McGarr, A.F., 2012, Relating stick-slip friction experiments to earthquake source parameters: Geophysical Research Letters, v. 39, no. 5, L05303; 5 p., https://doi.org/10.1029/2011GL050327.","productDescription":"L05303; 5 p.","ipdsId":"IP-035938","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":474689,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2011gl050327","text":"Publisher Index Page"},{"id":347895,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"39","issue":"5","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2012-03-03","publicationStatus":"PW","scienceBaseUri":"59f98bc2e4b0531197afa076","contributors":{"authors":[{"text":"McGarr, Arthur F. 0000-0001-9769-4093 mcgarr@usgs.gov","orcid":"https://orcid.org/0000-0001-9769-4093","contributorId":3178,"corporation":false,"usgs":true,"family":"McGarr","given":"Arthur","email":"mcgarr@usgs.gov","middleInitial":"F.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":715976,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
