This study examines the sensitivity of vegetation model simulations to: (i) the selection of input climatologies representing different time periods and their associated atmospheric CO<sub>2</sub> concentrations, (ii) the choice of observed vegetation data for evaluating the model results, and (iii) the methods used to compare simulated and observed vegetation. We use vegetation simulated for Asia by the equilibrium vegetation model BIOME4 as a typical example of vegetation model output. BIOME4 was run using 19 different climatologies and their associated atmospheric CO<sub>2</sub> concentrations. The Kappa statistic, Fuzzy Kappa statistic and a newly developed map-comparison method, the Nomad index, were used to quantify the agreement between the biomes simulated under each scenario and the observed vegetation from three different global land- and tree-cover data sets: the global Potential Natural Vegetation data set (PNV), the Global Land Cover Characteristics data set (GLCC), and the Global Land Cover Facility data set (GLCF). The results indicate that the 30-year mean climatology (and its associated atmospheric CO<sub>2</sub> concentration) for the time period immediately preceding the collection date of the observed vegetation data produce the most accurate vegetation simulations when compared with all three observed vegetation data sets. The study also indicates that the BIOME4-simulated vegetation for Asia more closely matches the PNV data than the other two observed vegetation data sets. Given the same observed data, the accuracy assessments of the BIOME4 simulations made using the Kappa, Fuzzy Kappa and Nomad index map-comparison methods agree well when the compared vegetation types consist of a large number of spatially continuous grid cells. The results of this analysis can assist model users in designing experimental protocols for simulating vegetation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Modelling","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","usgsCitation":"Tang, G., Shafer, S., Barlein, P.J., and Holman, J.O., 2009, Effects of experimental protocol on global vegetation model accuracy: a comparison of simulated and observed vegetation patterns for Asia: Ecological Modelling, v. 220, no. 12, p. 1481-1491.","productDescription":"11 p.","startPage":"1481","endPage":"1491","costCenters":[{"id":308,"text":"Geology and Environmental Change Science Center","active":false,"usgs":true}],"links":[{"id":204002,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":91768,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://www.sciencedirect.com/science/article/pii/S0304380009001999","linkFileType":{"id":5,"text":"html"}}],"otherGeospatial":"Asia","volume":"220","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2fe4b07f02db615b08","contributors":{"authors":[{"text":"Tang, Guoping","contributorId":31891,"corporation":false,"usgs":true,"family":"Tang","given":"Guoping","email":"","affiliations":[],"preferred":false,"id":349151,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shafer, Sarah L.","contributorId":32623,"corporation":false,"usgs":true,"family":"Shafer","given":"Sarah L.","affiliations":[],"preferred":false,"id":349152,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Barlein, Patrick J.","contributorId":75262,"corporation":false,"usgs":true,"family":"Barlein","given":"Patrick","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":349154,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Holman, Justin O.","contributorId":58384,"corporation":false,"usgs":true,"family":"Holman","given":"Justin","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":349153,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Predicting ecological and biogeographic responses to these changes constitutes an immense challenge for ecologists. Perspectives from climatic and ecological history indicate that responses will be laden with contingencies, resulting from episodic climatic events interacting with demographic and colonization events. This effect is compounded by the dependency of environmental sensitivity upon life-stage for many species. Climate variables often used in empirical niche models may become decoupled from the proximal variables that directly influence individuals and populations. Greater predictive capacity, and more-fundamental ecological and biogeographic understanding, will come from integration of correlational niche modeling with mechanistic niche modeling, dynamic ecological modeling, targeted experiments, and systematic observations of past and present patterns and dynamics.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the National Academy of Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"National Academy of Sciences","publisherLocation":"Washington, D.C.","usgsCitation":"Jackson, S.T., Betancourt, J.L., Booth, R.K., and Gray, S., 2009, Ecology and the ratchet of events: climate variability, niche dimensions, and species distributions: Proceedings of the National Academy of Sciences, v. 106, no.

This paper describes a long-term monitoring effort (15 years) on a stream restoration project in Glen Creek in Denali National Park and Preserve in Alaska. The stream channel and floodplain of Glen Creek had been severely degraded over a period of 80 years by placer mining for gold, which left many reaches with unstable and incised streambeds without functioning vegetated floodplains. The objectives of the original project, initiated in 1991, were to develop and test methods for the hydraulic design of channel and floodplain morphology and for floodplain stabilization and riparian habitat recovery, and to conduct research and monitoring to provide information for future projects in similar degraded watersheds. Monitoring methods included surveyed stream cross-sections, vegetation plots, and aerial, ground, and satellite photos. In this paper we address the immediate and outlying effects of a 25-year flood on the stream and floodplain geometry and riparian vegetation. The long-term monitoring revealed that significant channel widening occurred following the flood, likely caused by excessive upstream sediment loading and the fairly slow development of floodplain vegetation in this climate. Our results illustrated design flaws, particularly in regard to identification and analysis of sediment sources and the dominant processes of channel adjustment.","language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1752-1688.2009.00373.x","usgsCitation":"Densmore, R.V., and Karle, K.F., 2009, Flood effects on an Alaskan stream restoration project: the value of long-term monitoring: Journal of the American Water Resources Association, v. 45, no. 6, p. 1424-1433, https://doi.org/10.1111/j.1752-1688.2009.00373.x.","productDescription":"10 p.","startPage":"1424","endPage":"1433","costCenters":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":203974,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Denali National Park and Preserve","volume":"45","issue":"6","noUsgsAuthors":false,"publicationDate":"2009-12-03","publicationStatus":"PW","scienceBaseUri":"4f4e4acde4b07f02db67f3c7","contributors":{"authors":[{"text":"Densmore, Roseann V.","contributorId":24022,"corporation":false,"usgs":true,"family":"Densmore","given":"Roseann","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":347495,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Karle, Kenneth F.","contributorId":37461,"corporation":false,"usgs":true,"family":"Karle","given":"Kenneth","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":347496,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In contrast, spectrophotometric characterization of dissolved organic matter (DOM) is rapid, noninvasive, relatively inexpensive, requires small sample volumes, and can even be measured in situ to capture fine-scale temporal and spatial detail of DOM cycling. Here we present a series of cross-validated Partial Least Squares models that use fluorescence properties of DOM to explain up to 91% of lignin compositional and concentration variability in samples collected seasonally over 2 years in the Sacramento River/San Joaquin River Delta in California, United States. These models were subsequently used to predict lignin composition and concentration from fluorescence measurements collected during a diurnal study in the San Joaquin River. While modeled lignin composition remained largely unchanged over the diurnal cycle, changes in modeled lignin concentrations were much greater than expected and indicate that the sensitivity of fluorescence-based proxies for lignin may prove invaluable as a tool for selecting the most informative samples for detailed lignin characterization. With adequate calibration, similar models could be used to significantly expand our ability to study sources and processing of DOM in complex surface water systems.","language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2009JG000938","usgsCitation":"Hernes, P.J., Bergamaschi, B., Eckard, R.S., and Spencer, R., 2009, Fluorescence-based proxies for lignin in freshwater dissolved organic matter: Journal of Geophysical Research G: Biogeosciences, v. 114, no.

We report the successes and failures associated with artificial incubation of these eggs. Moisture loss varied widely, not only for Orders of birds but for similar species within an Order. Overall hatching success and success through to 90% of incubation varied for different Orders and for similar species. Humidity and temperature are critical elements in the artificial incubation of wild bird eggs and must be closely monitored throughout incubation to ensure the best possible chance of hatching. Even when these elements are addressed, artificial incubation still can not duplicate the success of incubation by the parent.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Avian Biology Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Science Reviews 2000 Ltd.","publisherLocation":"London, U.K.","usgsCitation":"Klimstra, J.D., Stebbins, K.R., Heinz, G.H., Hoffman, D.J., and Kondrad, S.R., 2009, Factors related to the artificial incubation of wild bird eggs: Avian Biology Research, v. 2, no. 3, p. 121-131.","productDescription":"11 p.","startPage":"121","endPage":"131","numberOfPages":"11","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203946,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":24573,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://stl.publisher.ingentaconnect.com/content/stl/abr/2009/00000002/00000003/art00002","linkFileType":{"id":5,"text":"html"}}],"volume":"2","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49ffe4b07f02db5f7c46","contributors":{"authors":[{"text":"Klimstra, Jon D.","contributorId":6985,"corporation":false,"usgs":false,"family":"Klimstra","given":"Jon","email":"","middleInitial":"D.","affiliations":[{"id":6661,"text":"US Fish and Wildlife Service","active":true,"usgs":false}],"preferred":false,"id":347358,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stebbins, Katherine R.","contributorId":94012,"corporation":false,"usgs":true,"family":"Stebbins","given":"Katherine","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":347362,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Heinz, Gary H.","contributorId":85698,"corporation":false,"usgs":true,"family":"Heinz","given":"Gary","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":347360,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hoffman, David J.","contributorId":86075,"corporation":false,"usgs":true,"family":"Hoffman","given":"David","email":"","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":347361,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kondrad, Shannon R.","contributorId":65977,"corporation":false,"usgs":true,"family":"Kondrad","given":"Shannon","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":347359,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Five-meter spacing of seismic sources and geophones produced high-resolution images of the subsurface adjacent to the 1766-m-depth Eyreville core holes. Analysis of these lines, in the context of the core hole stratigraphy, shows that moderate-amplitude, discontinuous, dipping reflections below ~527 m correlate with a variety of Chesapeake Bay impact structure sediment and rock breccias recovered in the cores. High-amplitude, continuous, subhorizontal reflections above ~527 m depth correlate with the uppermost part of the Chesapeake Bay impact structure crater-fill sediments and postimpact Eocene to Pleistocene sediments. Reflections with ~20-30 m of relief in the uppermost part of the crater-fill and lowermost part of the postimpact section suggest differential compaction of the crater-fill materials during early postimpact time. The top of the crater-fill section also shows ~20 m of relief that appears to represent an original synimpact surface. Truncation surfaces, locally dipping reflections, and depth variations in reflection amplitudes generally correlate with the lithostrati-graphic and sequence-stratigraphic units and contacts in the core. Seismic images show apparent postimpact paleochannels that include the first possible Miocene paleochannels in the Mid-Atlantic Coastal Plain. Broad downwarping in the postim-pact section unrelated to structures in the crater fill indicates postimpact sediment compaction.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","publisherLocation":"Boulder, CO","usgsCitation":"Powars, D.S., Catchings, R.D., Goldman, M.R., Gohn, G., Horton, J., Edwards, L.E., Rymer, M.J., and Gandhok, G., 2009, High-resolution seismic-reflection images across the ICDP-USGS Eyreville deep drilling site, Chesapeake Bay impact structure: Special Paper of the Geological Society of America, v. 458, p. 209-233.","productDescription":"25 p.","startPage":"209","endPage":"233","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":204077,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":24515,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://specialpapers.gsapubs.org/content/458/209.abstract","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Virginia","otherGeospatial":"Chesapeake Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.58333333333333,36.75 ], [ -76.58333333333333,37.583333333333336 ], [ -75.66666666666667,37.583333333333336 ], [ -75.66666666666667,36.75 ], [ -76.58333333333333,36.75 ] ] ] } } ] }","volume":"458","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db6887ec","contributors":{"authors":[{"text":"Powars, David S. 0000-0002-6787-8964 dspowars@usgs.gov","orcid":"https://orcid.org/0000-0002-6787-8964","contributorId":1181,"corporation":false,"usgs":true,"family":"Powars","given":"David","email":"dspowars@usgs.gov","middleInitial":"S.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":347453,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Catchings, Rufus D. 0000-0002-5191-6102 catching@usgs.gov","orcid":"https://orcid.org/0000-0002-5191-6102","contributorId":1519,"corporation":false,"usgs":true,"family":"Catchings","given":"Rufus","email":"catching@usgs.gov","middleInitial":"D.","affiliations":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true},{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":347454,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goldman, Mark R. 0000-0002-0802-829X goldman@usgs.gov","orcid":"https://orcid.org/0000-0002-0802-829X","contributorId":1521,"corporation":false,"usgs":true,"family":"Goldman","given":"Mark","email":"goldman@usgs.gov","middleInitial":"R.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":347455,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gohn, Gregory S.","contributorId":50155,"corporation":false,"usgs":true,"family":"Gohn","given":"Gregory S.","affiliations":[],"preferred":false,"id":347459,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Horton, J.

This study presents the results of the sclerochronology of modern specimens of S. gigantea, collected monthly from Pender Island (British Columbia), and additional modern specimens from the Dundas Islands (BC) and Mink and Little Takli Islands (Alaska). The methods presented can be used as a template to interpret local environmental conditions and increase the precision of seasonality estimates in shellfish using sclerochronology and oxygen isotope analysis. This method can also identify, with a high degree of accuracy, the date of shell collection to the nearest fortnightly cycle, the time of day the shell was collected and the approximate tidal elevation (i.e., approx. water depth and distance from the shoreline) from which the shell was collected.\n\nLife-history traits of S. gigantea were analyzed to understand the timing of growth line formation, the duration of the growing season, the growth rate, and the reliability of annual increments. We also examine the influence of the tidal regime and freshwater mixing in estuarine locations and how these variables can affect both incremental structures and oxygen isotope values. The results of the sclerochronological analysis show that there is a latitudinal trend in shell growth that needs to be considered when using shells for seasonality studies.\n\nOxygen isotope analysis reveals clear annual cycles with the most positive values corresponding to the annual winter growth lines, and the most negative values corresponding to high temperatures during the summer. Intra-annual increment widths demonstrate clear seasonal oscillations with broadest increments in summer and very narrow increments or no growth during the winter months. This study provides new insights into the biology, geochemistry and seasonal growth of S. gigantea, which are crucial for paleoclimate reconstructions and interpreting seasonality patterns of past human collection.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Archaeological Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","usgsCitation":"Hallman, N., Burchell, M., Schone, B.R., Irvine, G.V., and Maxwell, D., 2009, High-resolution sclerochronological analysis of the bivalve mollusk Saxidomus gigantea from Alaska and British Columbia: techniques for revealing environmental archives and archaeological seasonality: Journal of Archaeological Science, v. 36, no. 10, p. 2353-2364.","productDescription":"12 p.","startPage":"2353","endPage":"2364","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":24513,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://www.sciencedirect.com/science/article/pii/S0305440309002192","linkFileType":{"id":5,"text":"html"}},{"id":204050,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States;Canada","state":"Alaska;British Columbia","volume":"36","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db68885a","contributors":{"authors":[{"text":"Hallman, Nadine","contributorId":32662,"corporation":false,"usgs":false,"family":"Hallman","given":"Nadine","email":"","affiliations":[],"preferred":false,"id":347615,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burchell, Meghan","contributorId":15331,"corporation":false,"usgs":true,"family":"Burchell","given":"Meghan","email":"","affiliations":[],"preferred":false,"id":347614,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schone, Bernd R.","contributorId":58010,"corporation":false,"usgs":true,"family":"Schone","given":"Bernd","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":347616,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Irvine, Gail V. girvine@usgs.gov","contributorId":2368,"corporation":false,"usgs":true,"family":"Irvine","given":"Gail","email":"girvine@usgs.gov","middleInitial":"V.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":347613,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Maxwell, David","contributorId":85711,"corporation":false,"usgs":true,"family":"Maxwell","given":"David","email":"","affiliations":[],"preferred":false,"id":347617,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These models have several characteristics (e.g., they account for detectability) that make them particularly well suited for addressing management and conservation problems. We applied multistate site occupancy models to evaluate hypotheses related to the conservation and management of Golden Eagles (Aquila chrysaetos) in Denali National Park, Alaska, and provided estimates of transition probabilities among three occupancy states for nesting areas (occupied with successful reproduction, occupied with unsuccessful reproduction, and unoccupied). Our estimation models included the effect of potential recreational activities (hikers) and environmental covariates such as a snowshoe hare (Lepus americanus) index on transition probabilities among the three occupancy states. Based on the most parsimonious model, support for the hypothesis of an effect of potential human disturbance on site occupancy dynamics was equivocal. There was some evidence that potential human disturbance negatively affected local colonization of territories, but there was no evidence of an effect on reproductive performance parameters. In addition, models that assume a positive relationship between the hare index and successful reproduction were well supported by the data. The statistical approach that we used is particularly useful to parameterize management models that can then be used to make optimal decisions related to the management of Golden Eagles in Denali. Although in our case we were particularly interested in managing recreational activities, we believe that such models should be useful to for a broad class of management and conservation problems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.biocon.2009.06.027","usgsCitation":"Martin, J., McIntyre, C.L., Hines, J., Nichols, J., Schmutz, J.A., and MacCluskie, M.C., 2009, Dynamic multistate site occupancy models to evaluate hypotheses relevant to conservation of Golden Eagles in Denali National Park, Alaska: Biological Conservation, v. 142, no. 11, p. 2726-2731, https://doi.org/10.1016/j.biocon.2009.06.027.","productDescription":"6 p.","startPage":"2726","endPage":"2731","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":204151,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":21710,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1016/j.biocon.2009.06.027","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"Denali National Park","volume":"142","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a5ee4b07f02db633be8","contributors":{"authors":[{"text":"Martin, Julien 0000-0002-7375-129X julienmartin@usgs.gov","orcid":"https://orcid.org/0000-0002-7375-129X","contributorId":5785,"corporation":false,"usgs":true,"family":"Martin","given":"Julien","email":"julienmartin@usgs.gov","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":347351,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McIntyre, Carol L.","contributorId":94642,"corporation":false,"usgs":true,"family":"McIntyre","given":"Carol","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":347353,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hines, James E. jhines@usgs.gov","contributorId":3506,"corporation":false,"usgs":true,"family":"Hines","given":"James E.","email":"jhines@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":347350,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nichols, James D. 0000-0002-7631-2890 jnichols@usgs.gov","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":405,"corporation":false,"usgs":true,"family":"Nichols","given":"James D.","email":"jnichols@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":347348,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schmutz, Joel A. 0000-0002-6516-0836 jschmutz@usgs.gov","orcid":"https://orcid.org/0000-0002-6516-0836","contributorId":1805,"corporation":false,"usgs":true,"family":"Schmutz","given":"Joel","email":"jschmutz@usgs.gov","middleInitial":"A.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":347349,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"MacCluskie, Margaret C.","contributorId":50643,"corporation":false,"usgs":false,"family":"MacCluskie","given":"Margaret","email":"","middleInitial":"C.","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":347352,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The Fringe Wetlands consist of two separate planting cells. Fringe A, located adjacent to Lower Kingman Island, on the west bank of the Anacostia River, occupies 1.6 ha; Fringe B, located on the east bank of the Anacostia River, occupies 4.4 ha. This project is the third in a series of freshwater tidal wetland reconstructions on the Anacostia River designed and implemented by the US Army Corps of Engineers (USACE) Baltimore District and District Department of the Environment (DDOE) on lands managed by the National Park Service (NPS). The first was Kenilworth Marsh, reconstructed in 1993 (Syphax and Hammerschlag 2005); the second was Kingman Marsh, reconstructed in 2000 (Hammerschlag et al. 2006). Kenilworth and Kingman were both constructed in low-energy backwaters of the Anacostia. However, the Fringe Wetlands, which were constructed on two pre-existing benches along the high-energy mainstem, required sheet piling to provide protection from erosive impacts of increased flow and volume of water associated with storm events during the establishment phase (Photograph 2). All three projects required the placement of dredged sediment materials to increase elevations enough to support emergent vegetation (Photograph 3). The purpose of all three wetland reconstruction projects was to restore pieces of the once extensive tidal freshwater marsh habitat that bordered the Anacostia River historically, prior to the dredge and fill operations and sea wall installation that took place there in the early to mid-1900's (Photograph 4).","language":"English","publisher":"District Department of the Environment","publisherLocation":"Washington, D.C.","usgsCitation":"Krafft, C., Hammerschlag, R.S., and Guntenspergen, G.R., 2009, Anacostia River fringe wetlands restoration project: final report for the five-year monitoring program (2003 through 2007), vii, 22 p.; Photographs; Tables; Figures; Appendix.","productDescription":"vii, 22 p.; Photographs; Tables; Figures; Appendix","numberOfPages":"76","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203896,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","city":"Washington;D.C.","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad1e4b07f02db680f82","contributors":{"authors":[{"text":"Krafft, Cairn C.","contributorId":60364,"corporation":false,"usgs":true,"family":"Krafft","given":"Cairn C.","affiliations":[],"preferred":false,"id":347410,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hammerschlag, Richard S.","contributorId":67206,"corporation":false,"usgs":true,"family":"Hammerschlag","given":"Richard","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":347411,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guntenspergen, Glenn R. 0000-0002-8593-0244 glenn_guntenspergen@usgs.gov","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":2885,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"Glenn","email":"glenn_guntenspergen@usgs.gov","middleInitial":"R.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":347409,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Thus, genomic analyses of LPAI viruses could serve as an approach to prioritize species and regions targeted by North American surveillance activities for foreign origin highly pathogenic avian influenza (HPAI). To assess the applicability of this approach, we conducted a phylogenetic and population genetic analysis of 68 viral genomes isolated from the northern pintail (Anas acuta) at opposite ends of the Pacific migratory flyway in North America. We found limited evidence for Asian LPAI lineages on wintering areas used by northern pintails in California in contrast to a higher frequency on breeding locales of Alaska. Our results indicate that the number of Asian LPAI lineages observed in Alaskan northern pintails, and the nucleotide composition of LPAI lineages, is not maintained through fall migration. Accordingly, our data indicate that surveillance of Pacific Flyway northern pintails to detect foreign avian influenza viruses would be most effective in Alaska. North American surveillance plans could be optimized through an analysis of LPAI genomics from species that demonstrate evolutionary linkages with European or Asian lineages and in regions that have overlapping migratory flyways with areas of HPAI outbreaks.</p>","language":"English","publisher":"Wiley","publisherLocation":"Hoboken,

True geese are highly philopatric and acquire lifetime mates during the winter, suggesting that the number of distinct sub-populations may be related to the number of distinct wintering areas. In the Bar-headed Goose Anser indicus, a species found exclusively in Central Asia, the connectivity between breeding and wintering areas is not well known. Their migration includes crossing a broad front of the Himalaya Cordillera, a significant barrier to migration for most birds. Many Bar-headed Geese fly to breeding areas on the Tibetan-Qinghai Plateau (TQP), the highest plateau in the world. From 2005-2008, 60 Bar-headed Geese were captured and marked with satellite transmitters in Nepal (n = 2), India (n = 6), China (n = 29), and Mongolia (n = 23) to examine their migration and distribution. Distinct differences were observed in their migration corridors and timing of movements, including an apparent leap-frog migration pattern for geese from Mongolia. Measurements of geese from Mongolia were larger than their counterparts from China, providing some evidence of morphological differences. Alteration of habitats in China, including the warming effects of climate change on glaciers increasing runoff to TQP wetlands, may be changing goose migration patterns and timing. With the exception of one individual, all geese from Qinghai Lake, China wintered in the southern TQP near Lhasa, and their increasing numbers in that region may be related to the effects of climate change and agricultural development. Thus, our findings document both morphological and geographical variation in sub-populations of Bar-headed Geese, but their resilience to environmental change may be lost if migratory short-stopping results in larger congregations restricted to a smaller number of wintering areas.","language":"English","publisher":"Wildfowl and Wetlands Trust","publisherLocation":"Slimbridge,

We examined parasite richness and prevalence in 2 shorecrab species with different invasion histories and residency times in an introduced region where their distributions overlap broadly. On the northeastern coast of the USA, the Asian shorecrab Hemigrapsus sanguineus was discovered 20 yr ago, while the European green crab Carcinus maenas has been established for over 200 yr. We used literature and field surveys to evaluate parasitism in both crabs in their native and introduced ranges. We found only 1 parasite species infecting H. sanguineus on the US East Coast compared to 6 species in its native range, while C. maenas was host to 3 parasite species on the East Coast compared to 10 in its native range. The prevalence of parasite infection was also lower for both crabs in the introduced range compared to their native ranges; however, the difference was almost twice as much for H. sanguineus as for C. maenas. There are several explanations that could contribute to C. maenas' greater parasite diversity than that of H. sanguineus on the US East Coast, including differences in susceptibility, time since introduction, manner of introduction (vector), distance from native range, taxonomic isolation, and the potential for parasite identification bias. Our study underscores not just that non-native species lose parasites upon introduction, but that they may do so differentially, with ramifications for their direct interactions and with potential community-level influences.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Ecology Progress Series","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Inter-Research","publisherLocation":"Oldendorf/Luhe, Germany","doi":"10.3354/meps08225","usgsCitation":"Blakeslee, A.M., Keogh, C.L., Byers, J.E., Kuris, A.M., Lafferty, K.D., and Torchin, M.E., 2009, Differential escape from parasites by two competing introduced crabs: Marine Ecology Progress Series, v. 393, p. 83-96, https://doi.org/10.3354/meps08225.","productDescription":"8 p.","startPage":"83","endPage":"96","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":476001,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps08225","text":"Publisher Index Page"},{"id":204101,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":265990,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3354/meps08225"}],"country":"United States","otherGeospatial":"Europe;Northeastern Coast Of United States","volume":"393","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d701","contributors":{"authors":[{"text":"Blakeslee, April M.","contributorId":70101,"corporation":false,"usgs":true,"family":"Blakeslee","given":"April","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":348347,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keogh, Carolyn L.","contributorId":51007,"corporation":false,"usgs":true,"family":"Keogh","given":"Carolyn","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":348345,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Byers, James E.","contributorId":31892,"corporation":false,"usgs":true,"family":"Byers","given":"James","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":348344,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kuris, Armand M.","contributorId":54332,"corporation":false,"usgs":true,"family":"Kuris","given":"Armand","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":348346,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lafferty, Kevin D. 0000-0001-7583-4593 klafferty@usgs.gov","orcid":"https://orcid.org/0000-0001-7583-4593","contributorId":1415,"corporation":false,"usgs":true,"family":"Lafferty","given":"Kevin","email":"klafferty@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":348342,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Torchin, Mark E.","contributorId":25685,"corporation":false,"usgs":true,"family":"Torchin","given":"Mark","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":348343,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

In April 2006, the United States and Russia conducted an aerial survey of Pacific walrus (Odobenus rosmarus divergens) using thermal infrared sensors to detect groups of animals resting on pack ice in the Bering Sea. The goal of this survey was to estimate the size of the Pacific walrus population. An initial analysis of the U.S. data using previously-established methods resulted in lower detectability of walrus groups in the imagery and higher variability in calibration models than was expected based on pilot studies. This paper describes an improved procedure for detection and enumeration of walrus groups in airborne thermal imagery.  Thermal images were first subdivided into smaller 200 x 200 pixel \"tiles.\" We calculated three statistics to represent characteristics of walrus signatures from the temperature histogram for each the. Tiles that exhibited one or more of these characteristics were examined further to determine if walrus signatures were present. We used cluster analysis on tiles that contained walrus signatures to determine which pixels belonged to each group. We then calculated a thermal index value for each walrus group in the imagery and used generalized linear models to estimate detection functions (the probability of a group having a positive index value) and calibration functions (the size of a group as a function of its index value) based on counts from matched digital aerial photographs. The new method described here improved our ability to detect walrus groups at both 2 m and 4 m spatial resolution. In addition, the resulting calibration models have lower variance than the original method. We anticipate that the use of this new procedure will greatly improve the quality of the population estimate derived from these data. This procedure may also have broader applicability to thermal infrared surveys of other wildlife species.

We describe the technique and present maps of the co-located data sets. A global map and regional maps of Xanadu and the northern hemisphere hydrocarbon lakes district are included in the results. A strength of the technique is that it provides topographic information co-located with SAR imagery. Having a topographic context vastly improves the interpretability of the SAR imagery and is essential for understanding Titan.  SARTopo is capable of estimating surface heights for most of the SAR-imaged surface of Titan. Currently nearly 30% of the surface is within 100 km of a SARTopo height profile. Other competing techniques provide orders of magnitude less coverage.  We validate the SARTopo technique through comparison with known geomorphological features such as mountain ranges and craters, and by comparison with co-located nadir altimetry, including a 3000 km strip that had been observed by SAR a month earlier. In this area, the SARTopo and nadir altimetry data sets are co-located tightly (within 5-10 km for one 500 km section), have similar resolution, and as expected agree closely in surface height. Furthermore the region contains prominent high spatial resolution topography, so it provides an excellent test of the resolution and precision of both techniques.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal

We sampled rice fields (</span><i>n</i><span>&nbsp; =  39 [winter 2000–2001],&nbsp;</span><i>n</i><span>&nbsp; =  69 [2001–2002]) to estimate seed mass when waterfowl arrived in late autumn and departed in late winter. We also placed exclosures in subsets of fields in autumn (</span><i>n</i><span>&nbsp; =  8 [2000–2001],&nbsp;</span><i>n</i><span>&nbsp; =  20 [2001–2002]) and compared seed mass inside and outside exclosures in late winter to estimate rice depletion attributable to waterfowl and other processes. Finally, we used an experiment to determine if the extent of rice depletion differed among fields of varying initial abundance and if the seed mass at which waterfowl ceased foraging or abandoned fields differed from a hypothesized giving-up value of 50 kg/ha. Mean seed mass was greater in late autumn 2000 than 2001 (127.0 vs. 83.9 kg/ha;&nbsp;</span><i>P</i><span>&nbsp; =  0.018) but decreased more during winter 2000–2001 than 2001–2002 (91.3 vs. 55.7 kg/ha) and did not differ at the end of winter (35.8 vs. 28.3 kg/ha;&nbsp;</span><i>P</i><span>&nbsp; =  0.651). Assuming equal loss to deterioration inside and outside exclosures, we estimated waterfowl consumed 61.3 kg/ha (48.3%) of rice present in late autumn 2000 and 21.1 kg/ha (25.1%) in 2001. When we manipulated late-autumn rice abundance, mean giving-up mass of rice seed was similar among treatments (48.7 kg/ha;&nbsp;</span><i>P</i><span>&nbsp; =  0.205) and did not differ from 50 kg/ha (</span><i>P</i><span>&nbsp; =  0.726). We integrated results by constructing scenarios in which waterfowl consumed rice at different times in winter, consumption and deterioration were competing risks, and consumption occurred only above 50 kg/ha. Results indicated waterfowl likely consumed available rice soon after fields were flooded and the amount consumed exceeded our empirical estimates but was ≤48% (winters pooled) of rice initially present. We suggest 1) using 50 kg/ha as a threshold below which profitability limits waterfowl feeding in MAV rice fields; 2) reducing the current estimate (130 kg/ha) of rice consumed in harvested fields to 47.2 kg/ha; and 3) increasing available rice by increasing total area of fields managed, altering management practices (e.g., staggered flooding), and exploring the potential for producing second or ratoon rice crops for waterfowl.</span></p>","language":"English","publisher":"The Wildlife Society","doi":"10.2193/2008-250","usgsCitation":"Greer, D.M., Dugger, B., Reinecke, K.J., and Petrie, M.J., 2009, Depletion of rice as food of waterfowl wintering in the Mississippi Alluvial Valley: Journal of Wildlife Management, v. 73, no. 7, p. 1125-1133, https://doi.org/10.2193/2008-250.","productDescription":"9 p.","startPage":"1125","endPage":"1133","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":384154,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arkansas;Illinois;Kentucky;Louisiana;Mississippi;Missouri;Tennessee","otherGeospatial":"Mississippi Alluvial Valley","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -93,29 ], [ -93,38 ], [ -87,38 ], [ -87,29 ], [ -93,29 ] ] ] } } ] }","volume":"73","issue":"7","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"4f4e4ab1e4b07f02db66ea87","contributors":{"authors":[{"text":"Greer, Danielle M.","contributorId":19689,"corporation":false,"usgs":true,"family":"Greer","given":"Danielle","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":347106,"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":347107,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reinecke, Kenneth J.","contributorId":87275,"corporation":false,"usgs":true,"family":"Reinecke","given":"Kenneth","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":347108,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Petrie, Mark J.","contributorId":89655,"corporation":false,"usgs":true,"family":"Petrie","given":"Mark","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":347109,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Yet, signs of outcomes are not absolute, but vary with the biotic and abiotic contexts of interactions. Here, we develop a general theory for transitions between outcomes based on consumer-resource (C-R) interactions in which one or both species exploit the other as a resource. Simple models of C-R interactions revealed multiple equilibria, including one for species coexistence and others for extinction of one or both species, indicating that species densities alone could determine the fate of interactions. All possible outcomes (+ +), (+ -), (- -), (+ 0), (- 0), (0 0) of species coexistence emerged merely through changes in parameter values of C-R interactions, indicating that variation in C-R interactions resulting from biotic and abiotic conditions could determine shifts in outcomes. These results suggest that C-R interactions can provide a broad mechanism for understanding context- and density-dependent transitions between interaction outcomes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","usgsCitation":"Holland, J.N., and DeAngelis, D., 2009, Consumer-resource theory predicts dynamic transitions between outcomes of interspecific interactions: Ecology Letters, v. 12, no. 12, p. 1357-1366.","productDescription":"10 p.","startPage":"1357","endPage":"1366","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":203870,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":21949,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://onlinelibrary.wiley.com/doi/10.1111/j.1461-0248.2009.01390.x/abstract","linkFileType":{"id":5,"text":"html"}}],"volume":"12","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b12e4b07f02db6a2dd7","contributors":{"authors":[{"text":"Holland, J.

Species richness is often used as a tool for prioritizing conservation action. One method for predicting richness and other summaries of community structure is to develop species-specific models of occurrence probability based on habitat or landscape characteristics. However, this approach can be challenging for rare or elusive species for which survey data are often sparse.\r\n\r\n  2. Recent developments have allowed for improved inference about community structure based on species-specific models of occurrence probability, integrated within a hierarchical modelling framework. This framework offers advantages to inference about species richness over typical approaches by accounting for both species-level effects and the aggregated effects of landscape composition on a community as a whole, thus leading to increased precision in estimates of species richness by improving occupancy estimates for all species, including those that were observed infrequently.\r\n\r\n  3. We developed a hierarchical model to assess the community response of breeding birds in the Hudson River Valley, New York, to habitat fragmentation and analysed the model using a Bayesian approach.\r\n\r\n  4. The model was designed to estimate species-specific occurrence and the effects of fragment area and edge (as measured through the perimeter and the perimeter/area ratio, P/A), while accounting for imperfect detection of species.\r\n\r\n  5. We used the fitted model to make predictions of species richness within forest fragments of variable morphology. The model revealed that species richness of the observed bird community was maximized in small forest fragments with a high P/A. However, the number of forest interior species, a subset of the community with high conservation value, was maximized in large fragments with low P/A.\r\n\r\n  6. Synthesis and applications. Our results demonstrate the importance of understanding the responses of both individual, and groups of species, to environmental heterogeneity while illustrating the utility of hierarchical models for inference about species richness for conservation. This framework can be used to investigate the impacts of land-use change and fragmentation on species or assemblage richness, and to further understand trade-offs in species-specific occupancy probabilities associated with landscape variability.","language":"English","publisher":"British Ecological Society","doi":"10.1111/j.1365-2664.2009.01664.x","usgsCitation":"Zipkin, E., DeWan, A., and Royle, J., 2009, Impacts of forest fragmentation on species richness: A hierarchical approach to community modelling: Journal of Applied Ecology, v. 46, no. 4, p. 815-822, https://doi.org/10.1111/j.1365-2664.2009.01664.x.","productDescription":"8 p.","startPage":"815","endPage":"822","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":476002,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2664.2009.01664.x","text":"Publisher Index Page"},{"id":383722,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New York","otherGeospatial":"Hudson River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -73.8720703125,\n              40.74725696280421\n            ],\n            [\n              -73.80615234375,\n              41.244772343082076\n            ],\n            [\n              -73.8720703125,\n              41.672911819602085\n            ],\n            [\n              -73.751220703125,\n              42.049292638686836\n            ],\n            [\n              -73.685302734375,\n              42.593532625649935\n            ],\n            [\n              -73.641357421875,\n              42.924251753870685\n            ],\n            [\n              -73.8720703125,\n              42.79540065303723\n            ],\n            [\n              -73.970947265625,\n              42.23665188032057\n            ],\n            [\n              -74.058837890625,\n              41.75492216766298\n            ],\n            [\n              -74.058837890625,\n              41.269549502842565\n            ],\n            [\n              -74.058837890625,\n              40.863679665481676\n            ],\n            [\n              -73.8720703125,\n              40.74725696280421\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"46","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db6833f9","contributors":{"authors":[{"text":"Zipkin, Elise F.","contributorId":70528,"corporation":false,"usgs":true,"family":"Zipkin","given":"Elise F.","affiliations":[],"preferred":false,"id":347256,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DeWan, Amielle","contributorId":87036,"corporation":false,"usgs":true,"family":"DeWan","given":"Amielle","affiliations":[],"preferred":false,"id":347258,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Royle, J.

To validate the new method we weighed freshly laid chicken (Gallus gallus) eggs and then incubated sets of fertile and dead eggs for either 12 or 19 d. We then injected water into the air cells of these eggs and verified that the weights after water injection were almost identical to the weights of the eggs when they were fresh.
