Using high-resolution data from the Mars Reconnaissance Orbiter, we examine Cross crater’s basin-filling sedimentary deposits. Visible/shortwave infrared (VSWIR) spectra from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) show absorptions diagnostic of alunite. Combining spectral data with high-resolution images, we map a large (10 km × 5 km) alunite-bearing deposit in southwest Cross crater, widespread kaolin-bearing sediments with variable amounts of alunite that are layered in &lt;10 m scale beds, and silica- and/or montmorillonite-bearing deposits that occupy topographically lower, heavily fractured units. The secondary minerals are found at elevations ranging from 700 to 1550 m, forming a discontinuous ring along the crater wall beneath darker capping materials. The mineralogy inside Cross crater is different from that of the surrounding terrains and other martian basins, where Fe/Mg-phyllosilicates and Ca/Mg-sulfates are commonly found. Alunite in Cross crater indicates acidic, sulfurous waters at the time of its formation. Waters in Cross crater were likely supplied by regionally upwelling groundwaters as well as through an inlet valley from a small adjacent depression to the east, perhaps occasionally forming a lake or series of shallow playa lakes in the closed basin. Like nearby Columbus crater, Cross crater exhibits evidence for acid sulfate alteration, but the alteration in Cross is more extensive/complete. The large but localized occurrence of alunite suggests a localized, high-volume source of acidic waters or vapors, possibly supplied by sulfurous (H</span><sub>2</sub><span>S- and/or SO</span><sub>2</sub><span>-bearing) waters in contact with a magmatic source, upwelling steam or fluids through fracture zones. The unique, highly aluminous nature of the Cross crater deposits relative to other martian acid sulfate deposits indicates acid waters, high water throughput during alteration, atypically glassy and/or felsic materials, or a combination of these conditions.</span></p>","language":"English","publisher":"Mineralogical Society of America","doi":"10.2138/am-2016-5574","usgsCitation":"Ehlmann,

We radio-marked 196 individual rails and examined the evidence from 152 recovered California Ridgway’s rail mortalities from our radio-marked sample and determined plausible cause of death from a wide array of evidence. We also included 10 additional California Ridgway’s rail mortalities (unmarked) that we encountered during our normal field operations. We assigned a likely cause of death to 130 of the recoveries, of which 127 were determined to be caused by predation. Of those, 103 could be divided into class of cause (avian or mammalian), and avian predators were responsible for 64% of those events. Primary predators identified include domestic or feral cats, red fox, owl, and northern harrier. We did find seasonal differences between avian and mammalian predation rates, with higher proportions of avian predation in the winter and early spring. Time of day and tide height\nwere correlated with predation events, with a greater proportion of known mortalities found during periods of high tides (over 60% marsh inundation) and during daylight hours. Predation is the primary source of mortality for California Ridgway’s rail. Management actions that try to reduce avian predation may be the most effective at improving rail survival rates, given the proportion of avian predation detected.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the 27th Vertebrate Pest Conference","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"27th Vertebrate Pest Conference","conferenceDate":"March 7-10, 2016","conferenceLocation":"Newport Beach, CA","language":"English","publisher":"University of California, Davis","usgsCitation":"Casazza, M.L., Overton, C.T., Bui, T.D., Takekawa, J.Y., Merritt, A.M., and Hull, J., 2016, Depredation of the California Ridgway’s rail: Causes and distribution, <i>in</i> Proceedings of the 27th Vertebrate Pest Conference, Newport Beach, CA, March 7-10, 2016, p. 226-235.","productDescription":"10 p.","startPage":"226","endPage":"235","ipdsId":"IP-079366","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":351556,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5afee9d1e4b0da30c1bfc58e","contributors":{"authors":[{"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":726500,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Overton, Cory T. 0000-0002-5060-7447 coverton@usgs.gov","orcid":"https://orcid.org/0000-0002-5060-7447","contributorId":3262,"corporation":false,"usgs":true,"family":"Overton","given":"Cory","email":"coverton@usgs.gov","middleInitial":"T.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":726501,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bui, Thuy-Vy D. 0000-0002-0914-5439 tbui@usgs.gov","orcid":"https://orcid.org/0000-0002-0914-5439","contributorId":4776,"corporation":false,"usgs":true,"family":"Bui","given":"Thuy-Vy","email":"tbui@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":726502,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":196611,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":726503,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Merritt, Angela M. 0000-0002-8512-2423 amerritt@usgs.gov","orcid":"https://orcid.org/0000-0002-8512-2423","contributorId":201578,"corporation":false,"usgs":true,"family":"Merritt","given":"Angela","email":"amerritt@usgs.gov","middleInitial":"M.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":726504,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hull, J.M.","contributorId":201579,"corporation":false,"usgs":false,"family":"Hull","given":"J.M.","email":"","affiliations":[{"id":36209,"text":"U.S. FWS","active":true,"usgs":false}],"preferred":false,"id":726505,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Many ecosystems have more than one ungulate species; however, few studies have specifically examined the combined effects of two or more species on plant communities. We examined the extent to which two ungulate browsers (moose [</span><i>Alces americanus</i><span>]) and white-tailed deer [</span><i>Odocoileus virginianus</i><span>]) have additive (compounding) or compensatory (opposing) effects on herbaceous layer composition and diversity, 5–6&nbsp;years after timber harvest in Massachusetts, USA. We established three combinations of ungulates using two types of fenced exclosures – none (full exclosure), deer (partial exclosure), and deer&nbsp;+&nbsp;moose (control) in six replicated blocks. Species composition diverged among browser treatments, and changes were generally additive. Plant assemblages characteristic of closed canopy forests were less abundant and assemblages characteristic of open/disturbed habitats were more abundant in deer&nbsp;+&nbsp;moose plots compared with ungulate excluded areas.

Browsing by deer&nbsp;+&nbsp;moose resulted in strong changes to the composition, structure, and diversity of forest herbaceous layers, relative to areas free of ungulates and areas browed by white-tailed deer alone. Our results provide evidence that moderate browsing in forest openings can promote both herbaceous and woody plant diversity.

Data were collected during this project from another eight quick plots to support new vegetation types not previously identified at the Parkway. Data from 120 verification sites were collected to test the field key to vegetation associations and the application of vegetation associations to a sample set of map polygons.

Features were interpreted from viewing 4-band digital aerial imagery by means of digital onscreen three-dimensional stereoscopic workflow systems in geographic information systems. (The aerial imagery was collected during mid-October 2011 for the northern reach of the Parkway and mid-November 2011 for the southern reach of the Parkway to capture peak leaf-phenology of trees.)

A numerical groundwater flow model of the Inland Bays Watershed, Delaware, USA, was developed to identify the primary hydrogeologic factors that affect groundwater discharge rates and transit times to streams and bays. The distribution of groundwater discharge between streams and bays is sensitive to the depth of the water table below land surface. Higher recharge and reduced hydraulic conductivity raised the water table and increased discharge to streams relative to bays compared to the Reference case (in which 66% of recharge is discharged to streams). Increases to either factor decreased transit times for discharge to both streams and bays compared to the Reference case (in which mean transit times are 56.5 and 94.3&nbsp;years, respectively), though sensitivity to recharge is greater. Groundwater-borne nitrogen loads were calculated from nitrogen concentrations measured in discharging fresh groundwater and modeled SGD rates. These loads combined with long SGD transit times suggest groundwater-borne nitrogen reductions and estuarine water quality improvements will lag decades behind implementation of efforts to manage nutrient sources. This work enhances understanding of the hydrogeologic controls on and uncertainties in absolute and relative rates and transit times of groundwater discharge to streams and bays in coastal watersheds.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jhydrol.2016.05.013","usgsCitation":"Russoniello, C.J., Konikow, L.F., Kroeger, K.D., Fernandez, C., Andres, A., and Michael, H.A., 2016, Hydrogeologic controls on groundwater discharge and nitrogen loads in a coastal watershed: Journal of Hydrology, v. 538, p. 783-793, https://doi.org/10.1016/j.jhydrol.2016.05.013.","productDescription":"11 p.","startPage":"783","endPage":"793","ipdsId":"IP-071064","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":470791,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/1912/8150","text":"External Repository"},{"id":338942,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"538","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58df6ac0e4b02ff32c6aea2f","contributors":{"authors":[{"text":"Russoniello, Chrtopher J.","contributorId":190221,"corporation":false,"usgs":false,"family":"Russoniello","given":"Chrtopher","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":687831,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Konikow, Leonard F. 0000-0002-0940-3856 lkonikow@usgs.gov","orcid":"https://orcid.org/0000-0002-0940-3856","contributorId":158,"corporation":false,"usgs":true,"family":"Konikow","given":"Leonard","email":"lkonikow@usgs.gov","middleInitial":"F.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":687830,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kroeger, Kevin D. 0000-0002-4272-2349 kkroeger@usgs.gov","orcid":"https://orcid.org/0000-0002-4272-2349","contributorId":1603,"corporation":false,"usgs":true,"family":"Kroeger","given":"Kevin","email":"kkroeger@usgs.gov","middleInitial":"D.","affiliations":[{"id":41100,"text":"Coastal and Marine Hazards and Resources Program","active":true,"usgs":true}],"preferred":true,"id":687832,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fernandez, Cristina","contributorId":190222,"corporation":false,"usgs":false,"family":"Fernandez","given":"Cristina","email":"","affiliations":[],"preferred":false,"id":687833,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Andres, A.

Passive thermal tracer methods used to quantify vertical upwelling rates rely on downward conduction of surface temperature signals. However, moderate to high groundwater flux rates (&gt;−1.5 m d</span><sup>−1</sup><span>) restrict downward propagation of diurnal temperature signals, and therefore the applicability of several passive thermal methods. Active streambed heating from within high-resolution fiber-optic temperature sensors (A-HRTS) has the potential to define multidimensional fluid-flux patterns below the extinction depth of surface thermal signals, allowing better quantification and separation of local and regional groundwater discharge. To demonstrate this concept, nine A-HRTS were emplaced vertically into the streambed in a grid with ∼0.40 m lateral spacing at a stream with strong upward vertical flux in Mashpee, Massachusetts, USA. Long-term (8–9 h) heating events were performed to confirm the dominance of vertical flow to the 0.6 m depth, well below the extinction of ambient diurnal signals. To quantify vertical flux, short-term heating events (28 min) were performed at each A-HRTS, and heat-pulse decay over vertical profiles was numerically modeled in radial two dimension (2-D) using SUTRA. Modeled flux values are similar to those obtained with seepage meters, Darcy methods, and analytical modeling of shallow diurnal signals. We also observed repeatable differential heating patterns along the length of vertically oriented sensors that may indicate sediment layering and hyporheic exchange superimposed on regional groundwater discharge.</span></p>","language":"English","publisher":"AGU Publications","doi":"10.1002/2015WR018219","usgsCitation":"Briggs, M.A., Buckley, S.F., Bagtzoglou, A.C., Werkema, D.D., and Lane, J.W., 2016, Actively heated high-resolution fiber-optic-distributed temperature sensing to quantify streambed flow dynamics in zones of strong groundwater upwelling: Water Resources Research, v. 52, no. 7, p. 5179-5194, https://doi.org/10.1002/2015WR018219.","productDescription":"16 p.","startPage":"5179","endPage":"5194","ipdsId":"IP-074563","costCenters":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":470792,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2015wr018219","text":"Publisher Index Page"},{"id":339121,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"7","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2016-07-02","publicationStatus":"PW","scienceBaseUri":"58e4b0b2e4b09da679997794","contributors":{"authors":[{"text":"Briggs, Martin A. 0000-0003-3206-4132 mbriggs@usgs.gov","orcid":"https://orcid.org/0000-0003-3206-4132","contributorId":4114,"corporation":false,"usgs":true,"family":"Briggs","given":"Martin","email":"mbriggs@usgs.gov","middleInitial":"A.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true},{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true},{"id":493,"text":"Office of Ground Water","active":true,"usgs":true}],"preferred":true,"id":688338,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Buckley, Sean F. sbuckley@usgs.gov","contributorId":3910,"corporation":false,"usgs":true,"family":"Buckley","given":"Sean","email":"sbuckley@usgs.gov","middleInitial":"F.","affiliations":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true}],"preferred":true,"id":688339,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bagtzoglou, Amvrossios C.","contributorId":190400,"corporation":false,"usgs":false,"family":"Bagtzoglou","given":"Amvrossios","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":688340,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Werkema, Dale D.","contributorId":190401,"corporation":false,"usgs":false,"family":"Werkema","given":"Dale","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":688341,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lane, John W.

Fleas can reduce the fitness of hosts by interfering with immune responses, disrupting adaptive behaviors, and transmitting pathogens. The negative effects of fleas on hosts are usually most pronounced when fleas attain high densities. In lab studies, fleas desiccate and die under dry conditions, suggesting that populations of fleas will tend to decline when precipitation is scarce under natural conditions. To test this hypothesis, we compared precipitation vs. parasitism of black-tailed prairie dogs (</span><i>Cynomys ludovicianus</i><span>) by fleas at a single colony during May and June of 13 consecutive years (1976–1988) at Wind Cave National Park, South Dakota, USA. The number of fleas on prairie dogs decreased with increasing precipitation during both the prior growing season (April through August of the prior year) and the just-completed winter–spring (January through April of current year). Due to the reduction in available moisture and palatable forage in dry years, herbivorous prairie dogs might have been food-limited, with weakened behavioral and immunological defenses against fleas. In support of this hypothesis, adult prairie dogs of low mass harbored more fleas than heavier adults. Our results have implications for the spread of plague, an introduced bacterial disease, transmitted by fleas, that devastates prairie dog colonies and, in doing so, can transform grassland ecosystems.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1002/ecs2.1372","usgsCitation":"Eads, D.A., and Hoogland, J., 2016, Factors that affect parasitism of black-tailed prairie dogs by fleas: Ecosphere, v. 7, no. 7, p. 1-12, https://doi.org/10.1002/ecs2.1372.","productDescription":"e01372; 12 p.","startPage":"1","endPage":"12","ipdsId":"IP-073156","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":470793,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ecs2.1372","text":"Publisher Index Page"},{"id":332182,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"7","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2016-07-15","publicationStatus":"PW","scienceBaseUri":"5853ba41e4b0e2663625f2bc","chorus":{"doi":"10.1002/ecs2.1372","url":"http://dx.doi.org/10.1002/ecs2.1372","publisher":"Wiley-Blackwell","authors":"Eads David A., Hoogland John L.","journalName":"Ecosphere","publicationDate":"7/2016","auditedOn":"11/10/2016"},"contributors":{"authors":[{"text":"Eads, David A. 0000-0002-4247-017X deads@usgs.gov","orcid":"https://orcid.org/0000-0002-4247-017X","contributorId":173639,"corporation":false,"usgs":true,"family":"Eads","given":"David","email":"deads@usgs.gov","middleInitial":"A.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":655966,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hoogland, John L.","contributorId":113228,"corporation":false,"usgs":true,"family":"Hoogland","given":"John L.","affiliations":[],"preferred":false,"id":655967,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We demonstrate the imperative of framing clearly-defined management objectives in finding optimal control actions for control of disease outbreaks. We illustrate an analysis that can be applied rapidly at the start of an outbreak when there are multiple stakeholders involved with potentially multiple objectives, and when there are also multiple disease models upon which to compare control actions. The output of our analysis frames subsequent discourse between policy-makers, modellers and other stakeholders, by highlighting areas of discord among different management objectives and also among different models used in the analysis. We illustrate this approach in the context of a hypothetical foot-and-mouth disease (FMD) outbreak in Cumbria, UK using outputs from five rigorously-studied simulation models of FMD spread. We present both relative rankings and relative performance of controls within each model and across a range of objectives. Results illustrate how control actions change across both the base metric used to measure management success and across the statistic used to rank control actions according to said metric. This work represents a first step towards reconciling the extensive modelling work on disease control problems with frameworks for structured decision making.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.epidem.2015.11.002","usgsCitation":"Probert, W., Shea, K., Fonnesbeck, C.J., Runge, M.C., Carpenter, T.E., Durr, S., Garner, M., Harvey, N., Stevenson, M.A., Webb, C.T., Werkman, M., Tildesley, M., and Ferrari, M., 2016, Decision-making for foot-and-mouth disease control: Objectives matter: Epidemics, v. 15, p. 10-19, https://doi.org/10.1016/j.epidem.2015.11.002.","productDescription":"10 p.","startPage":"10","endPage":"19","ipdsId":"IP-070103","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":470780,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.epidem.2015.11.002","text":"Publisher Index Page"},{"id":329545,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58009d54e4b0824b2d183b87","contributors":{"authors":[{"text":"Probert, William J.

Raw counts or “minimum counts” are still used as a basis for wildlife management decisions. Uncorrected raw counts are not only negatively biased due to failure to account for undetected animals, but also provide no estimate of precision on which to judge the utility of counts. We applied a hybrid population estimation technique that combined sightability modeling, radio collar-based mark-resight, and simultaneous double count (double-observer) modeling to estimate the population size of elk in a high elevation desert ecosystem. Combining several models maximizes the strengths of each individual model while minimizing their singular weaknesses. We collected data with aerial helicopter surveys of the elk population in the San Luis Valley and adjacent mountains in Colorado State, USA in 2005 and 2007. We present estimates from 7 alternative analyses: 3 based on different methods for obtaining a raw count and 4 based on different statistical models to correct for sighting probability bias. The most reliable of these approaches is a hybrid double-observer sightability model (model M</span><sub>H</sub><span>), which uses detection patterns of 2 independent observers in a helicopter plus telemetry-based detections of radio collared elk groups. Data were fit to customized mark-resight models with individual sighting covariates. Error estimates were obtained by a bootstrapping procedure. The hybrid method was an improvement over commonly used alternatives, with improved precision compared to sightability modeling and reduced bias compared to double-observer modeling. The resulting population estimate corrected for multiple sources of undercount bias that, if left uncorrected, would have underestimated the true population size by as much as 22.9%. Our comparison of these alternative methods demonstrates how various components of our method contribute to improving the final estimate and demonstrates why each is necessary.</span></p>","language":"English","publisher":"King Saud University","doi":"10.1016/j.jksus.2015.09.004","usgsCitation":"Schoenecker, K.A., and Lubow, B., 2016, Application of a hybrid model to reduce bias and improve precision in population estimates for elk (Cervus elaphus) inhabiting a cold desert ecosystem: Journal of King Saud University - Science, v. 28, no. 3, p. 205-215, https://doi.org/10.1016/j.jksus.2015.09.004.","productDescription":"11 p.","startPage":"205","endPage":"215","ipdsId":"IP-061911","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":470786,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.jksus.2015.09.004","text":"Publisher Index Page"},{"id":346881,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"San Luis Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -106.270751953125,\n              37.49011473195046\n            ],\n            [\n              -105.556640625,\n              37.49011473195046\n            ],\n            [\n              -105.556640625,\n              38.58896696823242\n            ],\n            [\n              -106.270751953125,\n              38.58896696823242\n            ],\n            [\n              -106.270751953125,\n              37.49011473195046\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"28","issue":"3","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"59e86839e4b05fe04cd4d21c","contributors":{"authors":[{"text":"Schoenecker, Kathryn A. 0000-0001-9906-911X schoeneckerk@usgs.gov","orcid":"https://orcid.org/0000-0001-9906-911X","contributorId":2001,"corporation":false,"usgs":true,"family":"Schoenecker","given":"Kathryn","email":"schoeneckerk@usgs.gov","middleInitial":"A.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":713376,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lubow, Bruce C.","contributorId":59520,"corporation":false,"usgs":true,"family":"Lubow","given":"Bruce C.","affiliations":[],"preferred":false,"id":713547,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Therefore, it is important to understand how genomic reassortment and genetic polymorphisms affect phenotypes of H9N2 viruses circulating in the wild bird reservoir. A comparative genetic analysis of North American H9N2 isolates of wild bird origin identified a naturally occurring reassortant virus containing gene segments derived from both North American and Eurasian lineage ancestors. The PB2 segment of this virus encodes 10 amino acid changes that distinguish it from other H9 strains circulating in North America. G590S, one of the 10 amino acid substitutions observed, was present in ~ 12% of H9 viruses worldwide. This mutation combined with R591 has been reported as a marker of pathogenicity for human pandemic 2009 H1N1 viruses. Screening by polymerase reporter assay of all the natural polymorphisms at these two positions identified G590/K591 and S590/K591 as the most active, with the highest polymerase activity recorded for the SK polymorphism. Rescued viruses containing these two polymorphic combinations replicated more efficiently in MDCK cells and they were the only ones tested that were capable of establishing productive infection in NHBE cells. A global analysis of all PB2 sequences identified the K591 signature in six viral HA/NA subtypes isolated from several hosts in seven geographic locations. Interestingly, introducing the K591 mutation into the PB2 of a human-adapted H3N2 virus did not affect its polymerase activity. Our findings demonstrate that a single point mutation in the PB2 of a low pathogenic H9N2 isolate could have a significant effect on viral phenotype and increase its propensity to infect mammals. However, this effect is not universal, warranting caution in interpreting point mutations without considering protein sequence context.","language":"English","publisher":"Elsevier ","doi":"10.1016/j.meegid.2016.04.011","usgsCitation":"Hussein, I.T., Ma, E.J., Meixell, B.W., Hill, N., Lindberg, M.S., Albrecht, R.A., Bahl, J., and Runstadler, J.A., 2016, A point mutation in the polymerase protein PB2 allows a reassortant H9N2 influenza isolate of wild-bird origin to replicate in human cells.: Infection, Genetics and Evolution, v. 41, p. 279-288, https://doi.org/10.1016/j.meegid.2016.04.011.","productDescription":"10 p.","startPage":"279","endPage":"288","ipdsId":"IP-071158","costCenters":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":470788,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/1721.1/133904","text":"External Repository"},{"id":332680,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"586781f8e4b0cd2dabe7c71b","contributors":{"authors":[{"text":"Hussein, Islam T.M.","contributorId":177787,"corporation":false,"usgs":false,"family":"Hussein","given":"Islam","email":"","middleInitial":"T.M.","affiliations":[],"preferred":false,"id":657049,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ma, Eric J.","contributorId":177788,"corporation":false,"usgs":false,"family":"Ma","given":"Eric","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":657050,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Meixell, Brandt W. 0000-0002-6738-0349 bmeixell@usgs.gov","orcid":"https://orcid.org/0000-0002-6738-0349","contributorId":138716,"corporation":false,"usgs":true,"family":"Meixell","given":"Brandt","email":"bmeixell@usgs.gov","middleInitial":"W.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":657020,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hill, Nichola J.","contributorId":30342,"corporation":false,"usgs":true,"family":"Hill","given":"Nichola J.","affiliations":[],"preferred":false,"id":657051,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lindberg, Mark S.","contributorId":63292,"corporation":false,"usgs":false,"family":"Lindberg","given":"Mark","email":"","middleInitial":"S.","affiliations":[{"id":7211,"text":"University of Alaska, Fairbanks","active":true,"usgs":false}],"preferred":false,"id":657052,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Albrecht, Randy A.","contributorId":177789,"corporation":false,"usgs":false,"family":"Albrecht","given":"Randy","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":657053,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Bahl, Justin","contributorId":171803,"corporation":false,"usgs":false,"family":"Bahl","given":"Justin","affiliations":[{"id":26950,"text":"University of Texas School of Public Health, 1200 Pressler Street, Houston, TX 77030, USA","active":true,"usgs":false}],"preferred":false,"id":657054,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Runstadler, Jonathan A.","contributorId":24706,"corporation":false,"usgs":false,"family":"Runstadler","given":"Jonathan","email":"","middleInitial":"A.","affiliations":[{"id":12444,"text":"Massachusetts Institute of Technology","active":true,"usgs":false}],"preferred":false,"id":657055,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

To assess the vulnerability of grassland birds to climate change, we consider various components of vulnerability, including sensitivity, exposure, and adaptive capacity (Glick et al. 2011). Sensitivity encompasses the innate characteristics of a species and, in this context, is related to a species’ tolerance to changes in weather patterns. Groundnesting birds, including prairie birds, are particularly responsive to heat waves combined with drought conditions, as revealed by abundance and distribution patterns (Albright et al. 2010). To further assess sensitivity, we estimated reproductive parameters of nearly 3000 breeding attempts of a suite of prairie birds relative to prevailing weather. Fluctuations in weather conditions in eastern Colorado, 1997-2014, influenced breeding performance of a suite of avian species endemic to the shortgrass prairie, many of which have experienced recent population declines. High summer temperatures and intense rain events corresponded with lower nest survival for most species. Although dry&nbsp;conditions favored nest survival of Burrowing Owls and Mountain Plovers (Conrey 2010, Dreitz et al. 2012), drought resulted in smaller clutch sizes and lower nest survival for passerines (Skagen and Yackel Adams 2012, Conrey et al. in review). Declining summer precipitation may reduce the likelihood that some passerine species can maintain stable breeding populations in this region of the shortgrass prairie.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"America's Grasslands Conference: Partnerships for Grassland Conservation","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"America's Grasslands Conference: Partnerships for Grassland Conservation","conferenceDate":"September 29- October 1, 2015","conferenceLocation":"Fort Collins, CO","language":"English","publisher":"National Wildlife Federation","usgsCitation":"Skagen, S., Dreitz, V., Conrey, R.Y., Yackel, A., and Panjabi, A.O., 2016, Vulnerability of shortgrass prairie bird assemblages to climate change, <i>in</i> America's Grasslands Conference: Partnerships for Grassland Conservation, Fort Collins, CO, September 29- October 1, 2015, p. 100-101.","productDescription":"2 p.","startPage":"100","endPage":"101","ipdsId":"IP-073718","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":328138,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":326283,"type":{"id":15,"text":"Index Page"},"url":"https://www.nwf.org/~/media/PDFs/Misc/2015-Americas-Grasslands-Conference_Proceedings-FINAL-070816.ashx"}],"publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57c7ffc0e4b0f2f0cebfc353","contributors":{"editors":[{"text":"Knuffman, Lekha","contributorId":174191,"corporation":false,"usgs":false,"family":"Knuffman","given":"Lekha","email":"","affiliations":[],"preferred":false,"id":647670,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Skagen, Susan K. 0000-0002-6744-1244 skagens@usgs.gov","orcid":"https://orcid.org/0000-0002-6744-1244","contributorId":167829,"corporation":false,"usgs":true,"family":"Skagen","given":"Susan K.","email":"skagens@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":645035,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dreitz, Victoria","contributorId":172457,"corporation":false,"usgs":false,"family":"Dreitz","given":"Victoria","affiliations":[{"id":5097,"text":"University of Montana, Division of Biological Sciences","active":true,"usgs":false}],"preferred":false,"id":645036,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Conrey, Reesa Y.","contributorId":169966,"corporation":false,"usgs":false,"family":"Conrey","given":"Reesa","email":"","middleInitial":"Y.","affiliations":[{"id":16861,"text":"Colorado Parks and Wildlife Service","active":true,"usgs":false}],"preferred":false,"id":645037,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Yackel, Amy 0000-0002-7044-8447 yackela@usgs.gov","orcid":"https://orcid.org/0000-0002-7044-8447","contributorId":152310,"corporation":false,"usgs":true,"family":"Yackel","given":"Amy","email":"yackela@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":645038,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Panjabi, Arvind O.","contributorId":169967,"corporation":false,"usgs":false,"family":"Panjabi","given":"Arvind","email":"","middleInitial":"O.","affiliations":[{"id":25644,"text":"Bird Conservancy of the Rockies","active":true,"usgs":false}],"preferred":false,"id":645039,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
