KAHO contains a variety of culturally and ecologically significant water resources and water-related habitat for species that have been declared as threatened or endangered by the U.S. Fish and Wildlife Service, or are candidate threatened or endangered species. These habitats are dependent on coastal unconfined groundwater in a freshwater-lens system. The coastal unconfined-groundwater system is recharged by local infiltration of rainfall but also may receive recharge from an inland groundwater system containing groundwater impounded to high altitudes. The area inland of and near KAHO is being rapidly urbanized and increased groundwater withdrawals from the inland impounded-groundwater system may affect habitat and water quality in KAHO, depending on the extent of connection between the coastal unconfined groundwater and inland impounded-groundwater. An investigation of the geochemistry of surface-water and groundwater samples in and near KAHO was performed to evaluate the presence or absence of a connection between the inland impounded- and coastal unconfined-groundwater systems in the area. Analyses of major ions, selected trace elements, rare-earth elements, and strontium-isotope ratio results from ocean, fishpond, anchialine pool, and groundwater samples were consistent with a linear mixing process between the inland impounded and coastal unconfined-groundwater systems. Stable isotopes of water in many samples from the coastal unconfined-groundwater system require an aggregate recharge altitude that is substantially higher than the boundary between the coastal unconfined and inland impounded systems, a further indication of a hydrologic connection between the two systems. The stable isotope composition of the freshwater component of water samples from KAHO indicates that about 25&ndash;70% of the freshwater is derived from the inland impounded system.</span></p>","language":"English","publisher":"Elseiver","doi":"10.1016/j.apgeochem.2014.10.003","usgsCitation":"Tillman, F., Oki, D.S., Johnson, A.G., Barber, L.B., and Beisner, K.R., 2014, Investigation of geochemical indicators to evaluate the connection between inland and coastal groundwater systems near Kaloko-Honokōhau National Historical Park, Hawai‘i: Applied Geochemistry, v. 51, p. 278-292, https://doi.org/10.1016/j.apgeochem.2014.10.003.","productDescription":"15 p.","startPage":"278","endPage":"292","numberOfPages":"15","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-057293","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"links":[{"id":472521,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.apgeochem.2014.10.003","text":"Publisher Index Page"},{"id":297086,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kaloko-Honokōhau National Historical Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.08001708984375,\n              19.42126831604998\n            ],\n            [\n              -156.08001708984375,\n              19.73697619787738\n            ],\n            [\n              -155.84999084472656,\n              19.73697619787738\n            ],\n            [\n              -155.84999084472656,\n              19.42126831604998\n            ],\n            [\n              -156.08001708984375,\n              19.42126831604998\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"51","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a8ce4b08de9379b30ea","contributors":{"authors":[{"text":"Tillman, Fred D. 0000-0002-2922-402X ftillman@usgs.gov","orcid":"https://orcid.org/0000-0002-2922-402X","contributorId":1629,"corporation":false,"usgs":true,"family":"Tillman","given":"Fred D.","email":"ftillman@usgs.gov","affiliations":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"preferred":false,"id":537802,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Oki, Delwyn S. 0000-0002-6913-8804 dsoki@usgs.gov","orcid":"https://orcid.org/0000-0002-6913-8804","contributorId":1901,"corporation":false,"usgs":true,"family":"Oki","given":"Delwyn","email":"dsoki@usgs.gov","middleInitial":"S.","affiliations":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"preferred":true,"id":537803,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Adam G. 0000-0003-2448-5746 ajohnson@usgs.gov","orcid":"https://orcid.org/0000-0003-2448-5746","contributorId":4752,"corporation":false,"usgs":true,"family":"Johnson","given":"Adam","email":"ajohnson@usgs.gov","middleInitial":"G.","affiliations":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"preferred":true,"id":537804,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Barber, Larry B. 0000-0002-0561-0831 lbbarber@usgs.gov","orcid":"https://orcid.org/0000-0002-0561-0831","contributorId":921,"corporation":false,"usgs":true,"family":"Barber","given":"Larry","email":"lbbarber@usgs.gov","middleInitial":"B.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":537805,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Beisner, Kimberly R. 0000-0002-2077-6899 kbeisner@usgs.gov","orcid":"https://orcid.org/0000-0002-2077-6899","contributorId":2733,"corporation":false,"usgs":true,"family":"Beisner","given":"Kimberly","email":"kbeisner@usgs.gov","middleInitial":"R.","affiliations":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true},{"id":472,"text":"New Mexico Water Science Center","active":true,"usgs":true}],"preferred":true,"id":537806,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

High dissolved-solids loading to the River and tributaries are derived primarily from geologic material deposited in inland seas in the mid-to-late Cretaceous Period, but this loading may be increased by human activities. High dissolved solids in the River causes substantial damages to users, primarily in reduced agricultural crop yields and corrosion. The Colorado River Basin Salinity Control Program was created to manage dissolved-solids loading to the River and has focused primarily on reducing irrigation-related loading from agricultural areas. This work presents a reconnaissance of existing data from sites in the Upper Colorado River Basin (UCRB) in order to highlight areas where suspended-sediment control measures may be useful in reducing dissolved-solids concentrations. Multiple linear regression was used on data from 164 sites in the UCRB to develop dissolved-solids models that include combinations of explanatory variables of suspended sediment, flow, and time. Results from the partial&nbsp;</span><i>t</i><span>-test, overall likelihood ratio, and partial likelihood ratio on the models were used to group the sites into categories of strong, moderate, weak, and no-evidence of a relation between suspended-sediment and dissolved-solids concentrations. Results show 68 sites have strong or moderate evidence of a relation, with drainage areas for many of these sites composed of a large percentage of clastic sedimentary rocks. These results could assist water managers in the region in directing field-scale evaluation of suspended-sediment control measures to reduce UCRB dissolved-solids loading.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jhydrol.2014.08.020","usgsCitation":"Tillman, F., and Anning, D.W., 2014, A data reconnaissance on the effect of suspended-sediment concentrations on dissolved-solids concentrations in rivers and tributaries in the Upper Colorado River Basin: Journal of Hydrology, v. 519, no.

This report provides a detailed digital map and summary of irrigated areas within Osceola County for the agricultural growing period October 2013&ndash;April 2014. The irrigated areas were first delineated using land-use data and satellite imagery and then field verified between February and April 2014. Selected attribute data were collected for the irrigated areas, including crop type, primary water source, and type of irrigation system. Results indicate that an estimated 27,450 acres were irrigated during the study period. This includes 4,370 acres of vegetables, 10,970 acres of orchard crops, 1,620 acres of field crops, and 10,490 acres of ornamentals and grasses. Specifically, irrigated acreage included citrus (10,860 acres), sod (5,640 acres), pasture (4,580 acres), and potatoes (3,320 acres). Overall, groundwater was used to irrigate 18,350 acres (67 percent of the total acreage), and surface water was used to irrigate the remaining 9,100 acres (33 percent). Microirrigation systems accounted for 45 percent of the total acreage irrigated, flood systems 30 percent, and sprinkler systems the remaining 25 percent. An accurate, detailed, spatially referenced, and field-verified inventory of irrigated crop acreage can be used to assist resource managers making current and future county-level water-use estimates in Osceola County.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20141257","collaboration":"Florida Department of Agriculture and Consumer Services","usgsCitation":"Marella, R.L., and Dixon, J.F., 2014, Agricultural irrigated land-use inventory for Osceola County, Florida, October 2013-April 2014: U.S. Geological Survey Open-File Report 2014-1257, Report: 8 p.; 1 Appendix, https://doi.org/10.3133/ofr20141257.","productDescription":"Report: 8 p.; 1 Appendix","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-057250","costCenters":[{"id":5051,"text":"FLWSC-Orlando","active":true,"usgs":true}],"links":[{"id":297029,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20141257.jpg"},{"id":297026,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2014/1257/"},{"id":297027,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2014/1257/pdf/ofr2014-1257.pdf"},{"id":297028,"rank":3,"type":{"id":3,"text":"Appendix"},"url":"https://pubs.usgs.gov/of/2014/1257/pdf/ofr2014-1257_appendix1.pdf"}],"country":"United States","state":"Florida","county":"Osceola County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.9854736328125,\n              27.72243591897343\n            ],\n            [\n              -81.9854736328125,\n              28.65203063036226\n            ],\n            [\n              -80.7000732421875,\n              28.65203063036226\n            ],\n            [\n              -80.7000732421875,\n              27.72243591897343\n            ],\n            [\n              -81.9854736328125,\n              27.72243591897343\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2a51e4b08de9379b2fdc","contributors":{"authors":[{"text":"Marella, Richard L. 0000-0003-4861-9841 rmarella@usgs.gov","orcid":"https://orcid.org/0000-0003-4861-9841","contributorId":2443,"corporation":false,"usgs":true,"family":"Marella","given":"Richard","email":"rmarella@usgs.gov","middleInitial":"L.","affiliations":[{"id":5051,"text":"FLWSC-Orlando","active":true,"usgs":true},{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"preferred":true,"id":537293,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dixon, Joann F. 0000-0001-9200-6407 jdixon@usgs.gov","orcid":"https://orcid.org/0000-0001-9200-6407","contributorId":1756,"corporation":false,"usgs":true,"family":"Dixon","given":"Joann","email":"jdixon@usgs.gov","middleInitial":"F.","affiliations":[{"id":5051,"text":"FLWSC-Orlando","active":true,"usgs":true},{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true},{"id":269,"text":"FLWSC-Ft.

Sectors of active extension occur from the Indian Ocean, west to Botswana and the Democratic Republic of the Congo (DRC). It is the only rift system in the world that is active on a continent-wide scale, providing geologists with a view of how continental rifts develop over time into oceanic spreading centers like the Mid-Atlantic Ridge.</p>\n<p>Rifting in East Africa is not all coeval; volcanism and faulting have been an ongoing phenomenon on the continent since the Eocene (~45 Ma). The rifting began in northern East Africa, and led to the separation of the Nubia (Africa) and Arabia plates in the Red Sea and Gulf of Aden, and in the Lake Turkana area at the Kenya-Ethiopia border. A Paleogene mantle superplume beneath East Africa caused extension within the Nubia plate, as well as a first order topographic high known as the African superswell which now includes most of the eastern and southern sectors of the Nubia plate. Widespread volcanism erupted onto much of the rising plateau in Ethiopia during the Eocene-Oligocene (45&ndash;29 Ma), with chains of volcanoes forming along the rift separating Africa and Arabia. Since the initiation of rifting in northeastern Africa, the system has propagated over 3,000 km to the south and southwest, and it experiences seismicity as a direct result of the extension and active magmatism.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20101083P","usgsCitation":"Hayes, G.P., Jones, E.S., Stadler, T.J., Barnhart, W.D., McNamara, D.E., Benz, H.M., Furlong, K.P., and Villaseñor, A., 2014, Seismicity of the Earth 1900-2013 East African Rift: U.S. Geological Survey Open-File Report 2010-1083, Map: 26.94 x 39.20 inches, https://doi.org/10.3133/ofr20101083P.","productDescription":"Map: 26.94 x 39.20 inches","onlineOnly":"N","additionalOnlineFiles":"N","temporalStart":"1900-01-01","temporalEnd":"2013-12-31","ipdsId":"IP-057891","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":296976,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20101083P.jpg"},{"id":296975,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2010/1083/p/pdf/ofr2010-1083p.pdf","text":"Map","size":"13.0 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Map"},{"id":296973,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2010/1083/p/"}],"scale":"8500000","projection":"World Geodetic System 1984 Projection","otherGeospatial":"East African Rift","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              19.072265625,\n              -25.085598897064763\n            ],\n            [\n              19.072265625,\n              20.550508894195637\n            ],\n            [\n              49.92187499999999,\n              20.550508894195637\n            ],\n            [\n              49.92187499999999,\n              -25.085598897064763\n            ],\n            [\n              19.072265625,\n              -25.085598897064763\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2ab1e4b08de9379b3180","contributors":{"compilers":[{"text":"Hayes, Gavin P. 0000-0003-3323-0112 ghayes@usgs.gov","orcid":"https://orcid.org/0000-0003-3323-0112","contributorId":842,"corporation":false,"usgs":true,"family":"Hayes","given":"Gavin","email":"ghayes@usgs.gov","middleInitial":"P.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":538031,"contributorType":{"id":3,"text":"Compilers"},"rank":1},{"text":"Jones, Eric S. 0000-0002-9200-8442 esjones@usgs.gov","orcid":"https://orcid.org/0000-0002-9200-8442","contributorId":4924,"corporation":false,"usgs":true,"family":"Jones","given":"Eric","email":"esjones@usgs.gov","middleInitial":"S.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":538032,"contributorType":{"id":3,"text":"Compilers"},"rank":2},{"text":"Stadler, Timothy J.","contributorId":131172,"corporation":false,"usgs":false,"family":"Stadler","given":"Timothy","email":"","middleInitial":"J.","affiliations":[{"id":6672,"text":"former: USGS Southwest Biological Science Center, Colorado Plateau Research Station, Flagstaff, AZ.

However, there is little doubt that modern trade and transportation in support of the humans has continued to introduce additional species, genotypes, and hybrids to every country on the globe. We assessed the utility of species distributions modeling of genotypes to assess the risk of current and future invaders. We evaluated 93 locations of the genus <i>Tamarix</i> for which genetic data were available. Maxent models of habitat suitability showed that the hybrid, <i>T. ramosissima</i> x <i>T. chinensis</i>, was slightly greater than the parent taxa (AUCs &gt; 0.83). General linear models of Africanized honey bees, a hybrid cross of Tanzanian <i>Apis mellifera scutellata</i> and a variety of European honey bee including <i>A. m. ligustica</i>, showed that the Africanized bees (AUC = 0.81) may be displacing European honey bees (AUC &gt; 0.76) over large areas of the southwestern U.S. More important, Maxent modeling of sub-populations (A1 and A26 mitotypes based on mDNA) could be accurately modeled (AUC &gt; 0.9), and they responded differently to environmental drivers. This suggests that rapid evolutionary change may be underway in the Africanized bees, allowing the bees to spread into new areas and extending their total range. Protecting native species and ecosystems may benefit from risk maps of harmful invasive species, hybrids, and genotypes.</p>","language":"English","publisher":"Horizon Research Publishing","publisherLocation":"Alhambra, CA","doi":"10.13189/eer.2014.020804","usgsCitation":"Stohlgren, T.J., Szalanski, A.L., Gaskin, J.F., Young, N.E., West, A., Jarnevich, C.S., and Tripodi, A., 2014, From hybrid swarms to swarms of hybrids: Environment and Ecology Research, v. 2, no. 8, p. 311-318, https://doi.org/10.13189/eer.2014.020804.","productDescription":"8 p.","startPage":"311","endPage":"318","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-055483","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":472523,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.13189/eer.2014.020804","text":"Publisher Index Page"},{"id":298653,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"2","issue":"8","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5509502fe4b02e76d757e61d","contributors":{"authors":[{"text":"Stohlgren, Thomas J. 0000-0001-9696-4450 stohlgrent@usgs.gov","orcid":"https://orcid.org/0000-0001-9696-4450","contributorId":2902,"corporation":false,"usgs":true,"family":"Stohlgren","given":"Thomas","email":"stohlgrent@usgs.gov","middleInitial":"J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":539898,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Szalanski, Allen L.","contributorId":139057,"corporation":false,"usgs":false,"family":"Szalanski","given":"Allen","email":"","middleInitial":"L.","affiliations":[{"id":6623,"text":"University of Arkansas","active":true,"usgs":false}],"preferred":false,"id":539899,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gaskin, John F.","contributorId":39307,"corporation":false,"usgs":true,"family":"Gaskin","given":"John","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":539900,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Young, Nicholas E.","contributorId":58572,"corporation":false,"usgs":true,"family":"Young","given":"Nicholas","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":539901,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"West, Amanda M.","contributorId":139058,"corporation":false,"usgs":false,"family":"West","given":"Amanda M.","affiliations":[{"id":6737,"text":"Colorado State University, Department of Ecosystem Science and Sustainability, and Natural Resource Ecology Laboratory","active":true,"usgs":false}],"preferred":false,"id":539902,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jarnevich, Catherine S. 0000-0002-9699-2336 jarnevichc@usgs.gov","orcid":"https://orcid.org/0000-0002-9699-2336","contributorId":3424,"corporation":false,"usgs":true,"family":"Jarnevich","given":"Catherine","email":"jarnevichc@usgs.gov","middleInitial":"S.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":539897,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Tripodi, Amber","contributorId":139059,"corporation":false,"usgs":false,"family":"Tripodi","given":"Amber","email":"","affiliations":[{"id":6623,"text":"University of Arkansas","active":true,"usgs":false}],"preferred":false,"id":539903,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Using Oklahoma as an example, where invasive bighead carp (Hypophthalmichthys nobilis) are established in certain reservoirs, but predicted to be widely distributed based on broad-scale niche models, we cast bighead carp reproductive ecology in a site-specific geospatial framework to determine their potential establishment in additional reservoirs. Because bighead carp require large, long free-flowing rivers with suitable hydrology for reproduction but can persist in reservoirs, we considered reservoir tributaries with mean annual daily discharge &ge;8.5 cubic meters per second (m3 /s) and quantified the length of their unimpeded portions. In contrast to published broad-scale niche models that identified nearly the entire state as susceptible to invasion, our site-specific models showed that few reservoirs in Oklahoma (N = 9) were suitable for bighead carp establishment. Moreover, this method was rapid and identified sites that could be prioritized for increased study or scrutiny. Our results highlight the importance of considering the environmental characteristics of individual sites, which is often the level at which management efforts are implemented when assessing susceptibility to invasion.</p>","language":"English","publisher":"Regional Euro-Asian Biological Invasions Centre","publisherLocation":"Helsinki","doi":"10.3391/mbi.2014.5.4.07","usgsCitation":"Long, J.M., Liang, Y., Shoup, D.E., Dzialowski, A.R., and Bidwell, J.R., 2014, GIS-based rapid-assessment of bighead carp Hypophthalmichthys nobilis (Richardson, 1845) suitability in reservoirs: Management of Biological Invasions, v. 5, no. 4, p. 363-370, https://doi.org/10.3391/mbi.2014.5.4.07.","productDescription":"8 p.","startPage":"363","endPage":"370","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-037998","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":472524,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3391/mbi.2014.5.4.07","text":"Publisher Index Page"},{"id":305763,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oklahoma","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -94.48791503906249,\n              33.61461929233378\n            ],\n            [\n              -95.2020263671875,\n              33.94335994657882\n            ],\n            [\n              -96.361083984375,\n              33.67406853374198\n            ],\n            [\n              -96.932373046875,\n              33.88865750124075\n            ],\n            [\n              -97.119140625,\n              33.701492795584365\n            ],\n            [\n              -97.9705810546875,\n              33.87953701355924\n            ],\n            [\n              -98.1683349609375,\n              34.098159345215535\n            ],\n            [\n              -98.8165283203125,\n              34.116352469972746\n            ],\n            [\n              -99.1900634765625,\n              34.1890858311724\n            ],\n            [\n              -99.33837890625,\n              34.420504880133834\n            ],\n            [\n              -99.68994140625,\n              34.35250666867596\n            ],\n            [\n              -100.0250244140625,\n              34.551811369170494\n            ],\n            [\n              -100.03051757812499,\n              36.48314061639213\n            ],\n            [\n              -103.062744140625,\n              36.47872381162464\n            ],\n            [\n              -103.0517578125,\n              38.51378825951165\n            ],\n            [\n              -94.6142578125,\n              38.556757147352215\n            ],\n            [\n              -94.6142578125,\n              36.474306755095206\n            ],\n            [\n              -94.41650390625,\n              35.348735749472546\n            ],\n            [\n              -94.48791503906249,\n              33.61461929233378\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"5","issue":"4","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55a78438e4b0183d66e45e8a","contributors":{"authors":[{"text":"Long, James M. 0000-0002-8658-9949 jmlong@usgs.gov","orcid":"https://orcid.org/0000-0002-8658-9949","contributorId":3453,"corporation":false,"usgs":true,"family":"Long","given":"James","email":"jmlong@usgs.gov","middleInitial":"M.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":564319,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liang, Yu","contributorId":145642,"corporation":false,"usgs":false,"family":"Liang","given":"Yu","affiliations":[],"preferred":false,"id":564868,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shoup, Daniel E.","contributorId":141325,"corporation":false,"usgs":false,"family":"Shoup","given":"Daniel","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":564869,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dzialowski, Andrew R.","contributorId":145641,"corporation":false,"usgs":false,"family":"Dzialowski","given":"Andrew","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":564870,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bidwell, Joseph R.","contributorId":105122,"corporation":false,"usgs":true,"family":"Bidwell","given":"Joseph","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":564871,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In order to understand why excess N occurs various hydrologic systems (environments), it is important to consider potential sources, the locations of these sources in the watershed, and the timing of the application of sources with respect to the movement of water. To learn how to manage N in a watershed, it is necessary to identify and quantify flow paths and biogeochemical conditions, which ultimately combine to determine transport and fate. If sources, transport mechanisms, and biogeochemical controls were uniformly distributed, it would be possible to manage N uniformly throughout a watershed. However, uniform conditions are rare to nonexistent in the natural world and in the landscape altered for agricultural production. In order to adjust management activities on the landscape to have the greatest effect, it is important to understand the fate and transport N within the intersection of hydrology and biogeochemistry, that is, to understand the extent and duration of the hydrologic and biogeochemical controls as N is routed through and among each hydrologic compartment.</p>","language":"English","publisher":"Soil and Water Conservation Society","publisherLocation":"Ankeny, IA","doi":"10.2489/jswc.69.1.11A","usgsCitation":"Barlow, J.R., and Kröger, R., 2014, Nitrogen transport within an agricultural landscape: insights on how hydrology, biogeochemistry, and the landscape intersect to control the fate and transport of nitrogen in the Mississippi Delta: Journal of Soil and Water Conservation, v. 69, no. 1, p. 11A-16A, https://doi.org/10.2489/jswc.69.1.11A.","productDescription":"6 p.","startPage":"11A","endPage":"16A","numberOfPages":"6","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-052573","costCenters":[{"id":394,"text":"Mississippi Water Science Center","active":true,"usgs":true}],"links":[{"id":306625,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Mississippi Delta","volume":"69","issue":"1","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2014-01-06","publicationStatus":"PW","scienceBaseUri":"55cdbfbae4b08400b1fe1423","contributors":{"authors":[{"text":"Barlow, Jeannie R.

The first toxic bloom of GA in the western hemisphere occurred in the Pecos River, one of the saltiest rivers in North America. Environmental factors (water quality) associated with GA occurrence in this basin, however, have not been examined. Water quality and GA presence and abundance were determined at eight sites in the Pecos River basin with or without prior history of toxic blooms. Sampling was conducted monthly from January 2012 to July 2013. Specific conductance (salinity) varied spatiotemporally between 4408 and 73,786 mS/cm. Results of graphical, principal component (PCA), and zero-inflated Poisson (ZIP) regression analyses indicated that the incidence and abundance of GA are reduced as salinity increases spatiotemporally. LOWESS regression and correlation analyses of archived data for specific conductance and GA abundance at one of the study sites retrospectively confirmed the negative association between these variables. Results of PCA also suggested that at &lt;15,000 mS/cm, GA was present at a relatively wide range of nutrient (nitrogen and phosphorus) concentrations whereas at higher salinity, GA was observed only at mid-to-high nutrient levels. Generally consistent with earlier studies, results of ZIP regression indicated that GA presence is positively associated with organic phosphorus and in samples where GA is present, GA abundance is positively associated with organic nitrogen and negatively associated with inorganic nitrogen. This is the first report of an inverse relation between salinity and GA presence and abundance in riverine waters and of interaction effects of salinity and nutrients in the field. These observations contribute to a more complete understanding of environmental conditions that influence GA distribution in inland waters.</p>","language":"English","publisher":"Elsevier Science BV","publisherLocation":"Amsterdam","doi":"10.1016/j.hal.2014.06.012","usgsCitation":"Israel, N., VanLandeghem, M., Denny, S., Ingle, J., and Patino, R., 2014, Golden alga presence and abundance are inversely related to salinity in a high-salinity river ecosystem, Pecos River, USA: Harmful Algae, v. 39, no. 2014, p. 81-91, https://doi.org/10.1016/j.hal.2014.06.012.","productDescription":"11 p.","startPage":"81","endPage":"91","numberOfPages":"11","onlineOnly":"N","additionalOnlineFiles":"N","temporalStart":"2012-01-01","temporalEnd":"2013-07-31","ipdsId":"IP-052901","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":305844,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New Mexico, Texas","otherGeospatial":"Pecos River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.66650390625,\n              29.305561325527698\n            ],\n            [\n              -105.66650390625,\n              36.31512514748051\n            ],\n            [\n              -100.8544921875,\n              36.31512514748051\n            ],\n            [\n              -100.8544921875,\n              29.305561325527698\n            ],\n            [\n              -105.66650390625,\n              29.305561325527698\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"39","issue":"2014","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55af6d2be4b09a3b01b51aa4","contributors":{"authors":[{"text":"Israel, Natascha","contributorId":145737,"corporation":false,"usgs":false,"family":"Israel","given":"Natascha","email":"","affiliations":[],"preferred":false,"id":565135,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"VanLandeghem, Matthew M.","contributorId":143728,"corporation":false,"usgs":false,"family":"VanLandeghem","given":"Matthew M.","affiliations":[],"preferred":false,"id":565136,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Denny, Shawn","contributorId":145738,"corporation":false,"usgs":false,"family":"Denny","given":"Shawn","email":"","affiliations":[],"preferred":false,"id":565137,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ingle, John","contributorId":145739,"corporation":false,"usgs":false,"family":"Ingle","given":"John","email":"","affiliations":[],"preferred":false,"id":565138,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Patino, Reynaldo 0000-0002-4831-8400 r.patino@usgs.gov","orcid":"https://orcid.org/0000-0002-4831-8400","contributorId":2311,"corporation":false,"usgs":true,"family":"Patino","given":"Reynaldo","email":"r.patino@usgs.gov","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":556898,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Plumage may reliably convey information about disparate qualities such as age, condition, and parental ability because discrete tracts of feathers may cause individuals to incur different intrinsic or extrinsic costs. Few studies have examined the information content of plumage in a species that inhabits forest canopies, a habitat with unique light environments and selective pressures. We investigated the information content of four plumage patches (blue-green crown and rump, tail white, and black breast band) in a canopy-dwelling species, the Cerulean Warbler (</span><i>Setophaga cerulea</i><span>), in relation to age, condition, provisioning, and reproduction. We found that older males displayed wider breast bands, greater tail white, and crown and rump feathers with greater blue-green (435&ndash;534 nm) chroma and hue than males in their first potential breeding season. In turn, older birds were in better condition (short and long term) and were reproductively superior to younger birds. We propose that these age-related plumage differences (i.e. delayed plumage maturation) were not a consequence of a life history strategy but instead resulted from constraints during early feather molts. Within age classes, we found evidence to support the multiple messages hypothesis. Birds with greater tail white molted tails in faster, those with more exaggerated rump plumage (lower hue, greater blue-green chroma) provisioned more, and those with lower rump blue-green chroma were in better condition. Despite evidence of reliable signaling in this species, we found no strong relationships between plumage and reproductive performance, potentially because factors other than individual differences more strongly influenced fecundity.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1642/AUK-13-191.1","usgsCitation":"Boves, T.J., Buehler, D.A., Wood, P.B., Rodewald, A.D., Larkin, J.L., Keyser, P.D., and Wigley, T., 2014, Multiple plumage traits convey information about age and within-age-class qualities of a canopy-dwelling songbird, the Cerulean Warbler: The Auk, v. 131, no. 1, p. 20-31, https://doi.org/10.1642/AUK-13-191.1.","productDescription":"12 p.","startPage":"20","endPage":"31","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-038900","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":472541,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/auk-13-191.1","text":"Publisher Index Page"},{"id":321957,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"131","issue":"1","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5750076be4b0ee97d51bb686","contributors":{"authors":[{"text":"Boves, Than J.","contributorId":169750,"corporation":false,"usgs":false,"family":"Boves","given":"Than","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":631171,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Buehler, David A.","contributorId":169746,"corporation":false,"usgs":false,"family":"Buehler","given":"David","email":"","middleInitial":"A.","affiliations":[{"id":12716,"text":"University of Tennessee","active":true,"usgs":false}],"preferred":false,"id":631172,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wood, Petra Bohall pbwood@usgs.gov","contributorId":1791,"corporation":false,"usgs":true,"family":"Wood","given":"Petra","email":"pbwood@usgs.gov","middleInitial":"Bohall","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":false,"id":631061,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rodewald, Amanda D.","contributorId":169748,"corporation":false,"usgs":false,"family":"Rodewald","given":"Amanda","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":631173,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Larkin, Jeffrey L.","contributorId":169747,"corporation":false,"usgs":false,"family":"Larkin","given":"Jeffrey","email":"","middleInitial":"L.","affiliations":[{"id":17929,"text":"American Bird Conservancy","active":true,"usgs":false},{"id":34542,"text":"Department of Biology.

As the Pacific Plate of the Earth&rsquo;s lithosphere moves slowly northwestward over the Hawaiian hot spot, volcanoes are successively born above it, evolve as they drift away from it, and eventually die and subside beneath the ocean surface.</p>\n<p>The massive outpouring of lava flows from Hawaiian volcanoes weighs upon the oceanic crust, depressing it by as much as 5 km along an axial Hawaiian Moat. The periphery of subsidence is marked by the surrounding Hawaiian Arch. Subsidence is ongoing throughout almost all of a volcano&rsquo;s life.</p>\n<p>During its active life, an idealized Hawaiian volcano passes through four eruptive stages: preshield, shield, postshield, and rejuvenated. Though imperfectly named, these stages match our understanding of the growth history and compositional variation of the Hawaiian volcanoes; the stages reflect variations in the amount and rate of heat supplied to the lithosphere as it overrides the hot spot. Principal growth occurs in the first 1&ndash;2 million years as each volcano rises from the sea floor or submarine flank of an adjacent volcano. Volcanic extinction ensues as a volcano moves away from the hot spot.</p>\n<p>Eruptive-stage boundaries are drawn somewhat arbitrarily because of their transitional nature. Preshield-stage lava is alkalic as a consequence of a nascent magma-transport system and less extensive melting at the periphery of the mantle plume fed by the hot spot. The shield stage is the most productive volcanically, and each Hawaiian volcano erupts an estimated 80&ndash;95 percent of its ultimate volume in tholeiitic lavas during this stage. Shield-stage volcanism marks the time when a volcano is near or above the hot spot and its magma supply system is robust. This most active stage may also be the peak time when giant landslides modify the flanks of the volcanoes, although such processes begin earlier and extend later in the life of the volcanoes.</p>\n<p>Late-shield strata extend the silica range as alkali basalt and even hawaiite lava flows are sparsely interlayered with tholeiite at some volcanoes. Rare are more highly fractionated shield-stage lava flows, which may reach 68 weight percent SiO<sub>2</sub>. Intervolcano compositional differences result mainly from variations in the part of the mantle plume sampled by magmatism and the distribution of magma sources within it.</p>\n<p>Volcanism wanes gradually as Hawaiian volcanoes move away from the hot spot, passing from the shield stage into the postshield stage. Shallow magma reservoirs (1&ndash;7-km depth) of the shield-stage volcanoes cannot be sustained as magma supply lessens, but smaller reservoirs at 20&ndash;30-km depth persist. The rate of extrusion diminishes by a factor of 10 late in the shield stage, and the composition of erupted lava becomes more alkalic&mdash;albeit erratically&mdash;as the degree of melting diminishes. The variation makes this transition, from late shield to postshield, difficult to define rigorously. Of the volcanoes old enough to have seen this transition, eight have postshield strata sufficiently distinct and widespread to map separately. Only two, Ko&lsquo;olau and Lāna&lsquo;i, lack rocks of postshield composition.</p>\n<p>Five Hawaiian volcanoes have seen rejuvenated-stage volcanism following quiescent periods that ranged from 2.0 to less than 0.5 million years. The rejuvenated stage can be brief&mdash;only one or two eruptive episodes&mdash;or notably durable. That on Ni&lsquo;ihau lasted from 2.2 to 0.4 million years ago; on Kaua&lsquo;i, the stage has been ongoing since 3.5 million years ago. As transitions go, the rejuvenated stage may be thought of as the long tail of alkalic volcanism that begins in late-shield time and persists through the postshield (+rejuvenated-stage) era.</p>\n<p>Because successive Hawaiian volcanoes erupt over long and overlapping spans of time, there is a wide range in the age of volcanism along the island chain, even though the age of Hawaiian shields is progressively younger to the southeast. For example, almost every island from Ni&lsquo;ihau to Hawai&lsquo;i had an eruption in the time between 0.3 and 0.4 million years ago, even though only the Island of Hawai&lsquo;i had active volcanoes in their shield stage during that time.</p>\n<p>Once they have formed, Hawaiian volcanoes become subject to a spectrum of processes of degradation. Primary among these are subaerial erosion, landslides, and subsidence. The islands, especially those that grow high above sea level, experience mean annual precipitation that locally exceeds 9 m, leading to rapid erosion that can carve deep canyons in<br />less than 1 million years.</p>\n<p>Hawaiian volcanoes have also been modified by giant landslides. Seventeen discrete slides that formed in the past 5 m.y. have been identified around the main Hawaiian Islands, and fully 70 are known along the Hawaiian Ridge between Midway Islands and the Island of Hawai&lsquo;i. These giant landslides displace large amounts of seawater to generate catastrophic giant waves (megatsunami). The geologic evidence for megatsunami in the Hawaiian Islands includes chaotic coral and lava-clast breccia preserved as high as 155 m above sea level on Lāna&lsquo;i and Moloka&lsquo;i.</p>\n<p>Large Hawaiian volcanoes can persist as islands through the rapid subsidence by building upward rapidly enough. But in the long run, subsidence, coupled with surface erosion, erases any volcanic remnant above sea level in about 15 m.y. One consequence of subsidence, in concert with eustatic changes in sea level, is the drowning of coral reefs that drape the submarine flanks of the actively subsiding volcanoes. At least six reefs northwest of the Island of Hawai&lsquo;i form a stairstep configuration, the oldest being deepest.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Characteristics of Hawaiian volcanoes","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/pp18013","usgsCitation":"Clague, D.A., and Sherrod, D.R., 2014, Growth and degradation of Hawaiian volcanoes: U.S. Geological Survey Professional Paper 1801, 50 p., https://doi.org/10.3133/pp18013.","productDescription":"50 p.","startPage":"97","endPage":"146","numberOfPages":"50","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-038093","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":299345,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/pp18013.PNG"},{"id":296669,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/pp/1801/"},{"id":299344,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1801/downloads/pp1801_Chap3_Clague.pdf","text":"Report","size":"6.1 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Hawaii","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -160.68603515625,\n              21.657428197370653\n            ],\n            [\n              -160.0927734375,\n              22.19757745335104\n            ],\n            [\n              -159.54345703125,\n              22.350075806124867\n            ],\n            [\n              -157.884521484375,\n              21.85130210558968\n            ],\n            [\n              -155.709228515625,\n              20.86907773201848\n            ],\n            [\n              -154.44580078125,\n              19.580493479202538\n            ],\n            [\n              -154.698486328125,\n              18.3858049312974\n            ],\n            [\n              -155.555419921875,\n              18.145851771694467\n            ],\n            [\n              -156.390380859375,\n              18.895892559415024\n            ],\n            [\n              -156.73095703125,\n              20.066251024326302\n            ],\n            [\n              -158.323974609375,\n              21.135745255030603\n            ],\n            [\n              -159.730224609375,\n              21.70847301324598\n            ],\n            [\n              -160.499267578125,\n              21.361013117950915\n            ],\n            [\n              -160.68603515625,\n              21.657428197370653\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"551fb9b8e4b027f0aee3bb0c","contributors":{"editors":[{"text":"Poland, Michael P. 0000-0001-5240-6123 mpoland@usgs.gov","orcid":"https://orcid.org/0000-0001-5240-6123","contributorId":635,"corporation":false,"usgs":true,"family":"Poland","given":"Michael P.","email":"mpoland@usgs.gov","affiliations":[{"id":336,"text":"Hawaiian Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":543954,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Takahashi, T.

A companion paper shows how the model&rsquo;s five governing equations describe simultaneous evolution of flow thickness, solid volume fraction, basal pore-fluid pressure, and two components of flow momentum. Each equation contains a source term that represents the influence of state-dependent granular dilatancy. Here we recapitulate the equations and analyze their eigenstructure to show that they form a hyperbolic system with desirable stability properties. To solve the equations we use a shock-capturing numerical scheme with adaptive mesh refinement, implemented in an open-source software package we call D-Claw. As tests of D-Claw, we compare model output with results from two sets of large-scale debris-flow experiments. One set focuses on flow initiation from landslides triggered by rising pore-water pressures, and the other focuses on downstream flow dynamics, runout, and deposition. D-Claw performs well in predicting evolution of flow speeds, thicknesses, and basal pore-fluid pressures measured in each type of experiment. Computational results illustrate the critical role of dilatancy in linking coevolution of the solid volume fraction and pore-fluid pressure, which mediates basal Coulomb friction and thereby regulates debris-flow dynamics.</p>","language":"English","publisher":"The Royal Society","publisherLocation":"London, England","doi":"10.1098/rspa.2013.0820","usgsCitation":"George, D.L., and Iverson, R.M., 2014, A depth-averaged debris-flow model that includes the effects of evolving dilatancy: II.

In most online mapping systems, Web Mercator has become the dominant projection. While the Mercator projection has a long history of discussion about its inappropriateness for general-purpose mapping, particularly at the global scale, and seems to have been virtually phased out for general-purpose global-scale print maps, it has seen a resurgence in popularity in Web Mercator form. This article theorizes on how Web Mercator came to be widely used for online maps and what this might mean in terms of data display, technical aspects of map generation and distribution, design, and cognition of spatial patterns. The authors emphasize details of where the projection excels and where it does not, as well as some of its advantages and disadvantages for cartographic communication, and conclude with some research directions that may help to develop better solutions to the problem of projections for general-purpose, multi-scale Web mapping.</span></p>","language":"English","publisher":"University of Toronto Press","doi":"10.3138/carto.49.2.2313","usgsCitation":"Battersby, S.E., Finn, M.P., Usery, E.L., and Yamamoto, K.H., 2014, Implications of Web Mercator and its Use in Online Mapping: Cartographica: The International Journal for Geographic Information and Geovisualization, v. 49, no. 2, p. 85-101, https://doi.org/10.3138/carto.49.2.2313.","productDescription":"17 p.","startPage":"85","endPage":"101","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-053234","costCenters":[{"id":5047,"text":"NGTOC Denver","active":true,"usgs":true}],"links":[{"id":311160,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"49","issue":"2","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5643234de4b0aafbcd018018","contributors":{"authors":[{"text":"Battersby, Sarah E.","contributorId":138943,"corporation":false,"usgs":false,"family":"Battersby","given":"Sarah","email":"","middleInitial":"E.","affiliations":[{"id":12589,"text":"University of South Carolina/ Department of Geography","active":true,"usgs":false}],"preferred":false,"id":579218,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Finn, Michael P. 0000-0003-0415-2194 mfinn@usgs.gov","orcid":"https://orcid.org/0000-0003-0415-2194","contributorId":2657,"corporation":false,"usgs":true,"family":"Finn","given":"Michael","email":"mfinn@usgs.gov","middleInitial":"P.","affiliations":[{"id":5047,"text":"NGTOC Denver","active":true,"usgs":true},{"id":5074,"text":"Center for Geospatial Information Science (CEGIS)","active":true,"usgs":true}],"preferred":true,"id":579217,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Usery, E.

Globally, some amphibian population declines occurred in the late 1950s and early 1960s, and declining trends continued in North America (<a href=\"http://www.nature.com/nature/journal/v404/n6779/abs/404752a0.html\" target=\"_blank\" data-mce-href=\"http://www.nature.com/nature/journal/v404/n6779/abs/404752a0.html\">Houlahan et al. 2000</a>). In the earlier years, population declines were attributed primarily to overharvest due to unregulated supply of species such as the northern leopard frog (<i>Lithobate</i><i>s pipiens</i>) for educational use (<a href=\"https://jhupbooks.press.jhu.edu/content/frogs-united-states-and-canada-2-vol-set\" target=\"_blank\" data-mce-href=\"https://jhupbooks.press.jhu.edu/content/frogs-united-states-and-canada-2-vol-set\">Dodd</a>&nbsp;<a href=\"https://jhupbooks.press.jhu.edu/content/frogs-united-states-and-canada-2-vol-set\" data-mce-href=\"https://jhupbooks.press.jhu.edu/content/frogs-united-states-and-canada-2-vol-set\">2013</a>). In later years, however, causes of declines were less evident. In 1989, herpetologists at the First World Congress of Herpetology traded alarming stories of losses across continents and in seemingly protected landscapes, making it clear that amphibian population declines were a “global phenomenon.” In response to these reports, in 1991, the International Union for Conservation of Nature (IUCN) established the Declining Amphibian Populations Task Force to better understand the scale and scope of global amphibian declines. Unfortunately, the absence of long-term monitoring data and targeted studies made it difficult for the task force to compile information.</p><p>Today, according to AmphibiaWeb.org, there are 7,342 amphibian species in the world — double the number since the first alerts of declines — making the situation appear deceptively less dire. In fact, our understanding of genetic diversity significantly raises the stakes, and we are at risk of losing far more species than we believed only a few years ago. According to the IUCN, amphibians now lead the list of vertebrate taxa affected by the larger “biodiversity crisis” and sixth major mass- extinction event on Earth (<a href=\"http://onlinelibrary.wiley.com/doi/10.1111/cobi.12234/abstract\" target=\"_blank\" data-mce-href=\"http://onlinelibrary.wiley.com/doi/10.1111/cobi.12234/abstract\">Keith et al. 2014</a>,<span>&nbsp;</span><a href=\"http://www.sciencedirect.com/science/article/pii/0169534790901292\" data-mce-href=\"http://www.sciencedirect.com/science/article/pii/0169534790901292\">Wake</a><a href=\"http://www.sciencedirect.com/science/article/pii/0169534790901292\" target=\"_blank\" data-mce-href=\"http://www.sciencedirect.com/science/article/pii/0169534790901292\"><span>&nbsp;</span>and Vredenburg 2008</a>).</p>","language":"English","publisher":"The Wildlife Society","usgsCitation":"Olson, D.H., and Chestnut, T.E., 2014, Trouble in the aquatic world: How wildlife professionals are battling amphibian declines: The Wildlife Professional, v. 8, no. 4, p. 28-31.","productDescription":"4 p.","startPage":"28","endPage":"31","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-060298","costCenters":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"links":[{"id":319205,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":319204,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://wildlife.org/trouble-in-the-aquatic-world/"}],"volume":"8","issue":"4","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56f3be56e4b0f59b85e02f59","contributors":{"authors":[{"text":"Olson, Deanna H.","contributorId":114032,"corporation":false,"usgs":true,"family":"Olson","given":"Deanna","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":623250,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chestnut, Tara E. chestnut@usgs.gov","contributorId":3921,"corporation":false,"usgs":true,"family":"Chestnut","given":"Tara","email":"chestnut@usgs.gov","middleInitial":"E.","affiliations":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":623249,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We radio-tracked 3 female and 2 male Carolina northern flying squirrels during late winter through spring 2012 in the Pisgah National Forest, North Carolina, USA. Tracked squirrels used 13 yellow birch&nbsp;</span><i>Betula alleghaniensis</i><span>&nbsp;and 9 red spruce&nbsp;</span><i>Picea rubens</i><span>&nbsp;as diurnal dens. Ten of the yellow birch dens were in cavities, whereas the remainders were dreys. Conversely, 8 of the red spruce dens were dreys and one was in a cavity. Mean (&plusmn;SE) female 95 and 50% adaptive kernel home ranges were 6.50 &plusmn; 2.19 and 0.93 &plusmn; 0.33 ha, respectively, whereas the corresponding values for males were 12.6 &plusmn; 0.9 and 1.45 &plusmn; 0.1 ha, respectively. Squirrels used red spruce stands with canopies &gt;20 m more than expected based on availability at the landscape and home range scales. Results should be interpreted cautiously because of small sample sizes and seasonal observations; however, they provide evidence that although northern hardwoods such as yellow birch are an important den habitat component, mature red spruce-dominated habitats with complex structure provide foraging habitats and are also den habitat. Our findings support efforts to improve the structural condition of extant red spruce forests and/or increase red spruce acreage to potentially benefit Carolina northern flying squirrels.</span></p>","language":"English","publisher":"Inter-Research","doi":"10.3354/esr00561","usgsCitation":"Ford, W.M., Kelly, C.A., Rodrigue, J.L., Odom, R.H., Newcomb, D., Gilley, L.M., and Diggins, C.A., 2014, Late winter and early spring home range and habitat use of the endangered Carolina northern flying squirrel in western North Carolina: Endangered Species Research, v. 23, no. 1, p. 73-82, https://doi.org/10.3354/esr00561.","productDescription":"10 p.","startPage":"73","endPage":"82","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-046139","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":472538,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/esr00561","text":"Publisher Index Page"},{"id":323397,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"North Carolina","otherGeospatial":"Middle Prong Wilderness, Pisgah National Forest","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -83.02436828613281,\n              35.25459097465022\n            ],\n            [\n              -83.02436828613281,\n              35.41311690821499\n            ],\n            [\n              -82.8533935546875,\n              35.41311690821499\n            ],\n            [\n              -82.8533935546875,\n              35.25459097465022\n            ],\n            [\n              -83.02436828613281,\n              35.25459097465022\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"23","issue":"1","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"575a9333e4b04f417c275164","contributors":{"authors":[{"text":"Ford, W.

Unfortunately, chronicling fault slip with techniques like thermochronology and geodetics can still leave sizable, yet potentially important gaps at Pliocene&ndash;Quaternary (&sim;105&ndash;106 yr) time scales. Here, we combine existing geochronology with new geomorphic observations and approaches to investigate the Miocene to Quaternary slip history of active normal faults that are exhuming three footwall ranges in northwestern Nevada: the Pine Forest Range, the Jackson Mountains, and the Santa Rosa Range. We use the National Elevation Dataset (10 m) digital elevation model (DEM) to measure bedrock river profiles and hillslope gradients from these ranges. We observe a prominent suite of channel convexities (knickpoints) that segment the channels into upper reaches with low steepness (mean k<sub>sn</sub> = &sim;182; &theta;<sub>ref</sub> = 0.51) and lower, fault-proximal reaches with high steepness (mean k<sub>sn</sub> = &sim;361), with a concomitant increase in hillslope angles of &sim;6&deg;&ndash;9&deg;. Geologic maps and field-based proxies for rock strength allow us to rule out static causes for the knickpoints and interpret them as transient features triggered by a drop in base level that created &sim;20% of the existing relief (&sim;220 m of &sim;1050 m total). We then constrain the timing of base-level change using paleochannel profile reconstructions, catchment-scale volumetric erosion fluxes, and a stream-power&ndash;based knickpoint celerity (migration) model. Low-temperature thermochronology data show that faulting began at ca. 11&ndash;12 Ma, yet our results estimate knickpoint initiation began in the last 5 Ma and possibly as recently as 0.1 Ma with reasonable migration rates of 0.5&ndash;2 mm/yr. We interpret the collective results to be evidence for enhanced Pliocene&ndash;Quaternary fault slip that may be related to tectonic reorganization in the American West, although we cannot rule out climate as a contributing mechanism. We propose that similar studies, which remain remarkably rare across the region, be used to further test how robust this Plio&ndash;Quaternary landscape signal may be throughout the Great Basin.</p>","language":"English","publisher":"Geological Society of America","publisherLocation":"Boulder, CO","doi":"10.1130/L401.1","usgsCitation":"Ellis, M.A., B, B.J., and Colgan, J.P., 2014, Geomorphic evidence for enhanced Pliocene-Quaternary faulting in the northwestern Basin and Range: Lithosphere, v. 7, no. 1, p. 59-72, https://doi.org/10.1130/L401.1.","productDescription":"14 p.","startPage":"59","endPage":"72","numberOfPages":"15","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-057543","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":472528,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/l401.1","text":"Publisher Index Page"},{"id":306647,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"U.S. Basin and Range Province","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.26953125,\n              42.68243539838623\n            ],\n            [\n              -119.88281249999999,\n              42.65012181368025\n            ],\n            [\n              -120.73974609374999,\n              39.18117526158749\n            ],\n            [\n              -117.57568359374999,\n              36.26199220445664\n            ],\n            [\n              -114.08203125,\n              36.63316209558658\n            ],\n            [\n              -111.11572265625,\n              40.27952566881291\n            ],\n            [\n              -111.26953125,\n              42.68243539838623\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"7","issue":"1","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55cdbfb3e4b08400b1fe1402","contributors":{"authors":[{"text":"Ellis, Magdalena A","contributorId":146227,"corporation":false,"usgs":false,"family":"Ellis","given":"Magdalena","email":"","middleInitial":"A","affiliations":[{"id":16637,"text":"University of North Carolina, Chapel Hill","active":true,"usgs":false}],"preferred":false,"id":566677,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"B, Barnes Jason","contributorId":146228,"corporation":false,"usgs":false,"family":"B","given":"Barnes","email":"","middleInitial":"Jason","affiliations":[{"id":16637,"text":"University of North Carolina, Chapel Hill","active":true,"usgs":false}],"preferred":false,"id":566678,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Colgan, Joseph P. 0000-0001-6671-1436 jcolgan@usgs.gov","orcid":"https://orcid.org/0000-0001-6671-1436","contributorId":1649,"corporation":false,"usgs":true,"family":"Colgan","given":"Joseph","email":"jcolgan@usgs.gov","middleInitial":"P.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":566676,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Migratory miller moths (Euxoa auxiliaris) were unusually abundant in Fort Collins in spring and autumn of 2002 and are known agricultural pests as larvae (army cutworms), suggesting that seasonal dietary flexibility in big brown bats has economic benefits.</p>","language":"English","publisher":"Southwestern Association of Naturalists","publisherLocation":"Washington, D.C.","doi":"10.1894/SGM-28.1","usgsCitation":"Valdez, E.W., and O’Shea, T.J., 2014, Seasonal shifts in the diet of the big brown bat (Eptesicus fuscus), Fort Collins, Colorado: Southwestern Naturalist, v. 59, no. 4, p. 511-516, https://doi.org/10.1894/SGM-28.1.","productDescription":"6 p.","startPage":"511","endPage":"516","numberOfPages":"7","onlineOnly":"N","additionalOnlineFiles":"N","temporalStart":"2002-05-01","temporalEnd":"2002-09-30","ipdsId":"IP-055474","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":306651,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","city":"Fort Collins","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.1666259765625,\n              40.46575594018434\n            ],\n            [\n              -105.1666259765625,\n              40.64730356252251\n            ],\n            [\n              -104.91668701171875,\n              40.64730356252251\n            ],\n            [\n              -104.91668701171875,\n              40.46575594018434\n            ],\n            [\n              -105.1666259765625,\n              40.46575594018434\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"59","issue":"4","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55cdbfbce4b08400b1fe1437","contributors":{"authors":[{"text":"Valdez, Ernest W. 0000-0002-7262-3069 ernie@usgs.gov","orcid":"https://orcid.org/0000-0002-7262-3069","contributorId":3600,"corporation":false,"usgs":true,"family":"Valdez","given":"Ernest","email":"ernie@usgs.gov","middleInitial":"W.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":565619,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Shea, Thomas J. osheat@usgs.gov","contributorId":2327,"corporation":false,"usgs":true,"family":"O’Shea","given":"Thomas","email":"osheat@usgs.gov","middleInitial":"J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":565620,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
