Granitic rocks are\ndelineated most clearly by potassium highs and less clearly by thorium highs. Nearly all the\nthorium highs other than those related to granites are associated with amphibolite-facies rocks of\nthe Raleigh and Triplet terranes. Contrasting thorium lows within these terranes help to distinguish\nthe individual rock units. In the Carolina and Roanoke Rapids terranes, high-gradient magnetic\npatterns delineate stratified metavolcanic and metasedimentary units that are not discernible from\nthe gamma-ray surveys. Circular magnetic highs coincide with gabbro plutons, and numerous\nmagnetic lineaments correspond to Jurassic diabase dikes. Magnetically uniform, low-gradient\nareas coincide with less mafic plutons. A magnetic lineament (high) coincides with the Nutbush\nCreek fault zone, and other faults are distinguished as boundaries between zones of contrasting\ngeophysical properties.

B.S.P.) growing at the extreme western range of the species are in danger of being lost, and information on the ecology of these populations is limited. Seeds and seedlings (\"wildlings\") were collected near Vancleave, MS. The wildlings were transplanted to bay-head sites on Bogue Chitto National Wildlife Refuge where canopy gaps had been created in early 1989. Seeds were germinated, grown in a greenhouse, and transplanted a year later to three locations within a slash pine plantation: a bedded and fertilized site, the margin of a cypress pond, and a wet gap, in St. Tammany Parish, Lousiana. These plantings were established to study survival and growth in different habitat types, to compare seedlings grown from seed versus transplanted wildlings, and to attempt to generate some interest in planting Atlantic white-cedar in the extreme western portion of its natural range.&nbsp;</div><div><br></div><div>Overall seedling survival averaged 94 percent after five growing seasons, although significant differences were detected among sites. Mean height per site in 1994 was significantly greater at the bedded and fertilized site (233 centimeters), and lowest at the slash pine site (91 centimeters). Growth at the cypress pond site was intermediate (158 centimeters). Wildlings at the bay-head sites had lower survival rates (75 and 64 percent), but average heights for the two sites were similar to those of the seedlings (265 and 165 centimeters). These results show that plantings involving either local seed or wildlings are viable choices for regenerating Atlantic white-cedar in southern Mississippi and eastern Louisiana.</div>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings Atlantic white-cedar: Ecology and management symposium ","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Atlantic white-cedar: Ecology and management symposium ","conferenceDate":"August 6-7, 1997","conferenceLocation":"Asheville, North Carolina","language":"English","publisher":"U.S. Department of Agriculture","usgsCitation":"McCoy, J.W., Keeland, B.D., and Allen, J., 1999, Atlantic white cedar plantings in St. Tammany Parish, Louisiana, and the Bogue Chitto National Wildlife Refuge, Mississippi, <i>in</i> Proceedings Atlantic white-cedar: Ecology and management symposium , Asheville, North Carolina, August 6-7, 1997, p. 36-41.","productDescription":"6 p.","startPage":"36","endPage":"41","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":360355,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":360354,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.fs.usda.gov/treesearch/pubs/897"}],"country":"United States","state":"Louisiana; Mississippi","otherGeospatial":"Bogue Chitto National Wildlife Refuge; St. Tammany Parish","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c18c426e4b006c4f856acee","contributors":{"authors":[{"text":"McCoy, John W. 0000-0003-3013-730X mccoyj@usgs.gov","orcid":"https://orcid.org/0000-0003-3013-730X","contributorId":3082,"corporation":false,"usgs":true,"family":"McCoy","given":"John","email":"mccoyj@usgs.gov","middleInitial":"W.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":754390,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keeland, Bobby D.","contributorId":103506,"corporation":false,"usgs":true,"family":"Keeland","given":"Bobby","email":"","middleInitial":"D.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":754391,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Allen, James A. 0000-0001-6459-5734","orcid":"https://orcid.org/0000-0001-6459-5734","contributorId":108095,"corporation":false,"usgs":true,"family":"Allen","given":"James A.","affiliations":[],"preferred":false,"id":754392,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although the onset, duration, and cessation of the bloom remain unpredictable, ground-water discharge has been shown to affect surface-water quality in the western part of the estuary. Results from a study on the North Fork of Long Island indicate that local hydrogeologic factors cause differences in ground-water age and characteristics of discharge to the estuary. The need for information on the local patterns and rates of ground-water discharge to the Peconic Estuary prompted analysis of ground-water flow paths and traveltime to three small embayments within the estuary. Meetinghouse Creek, near the west end of the North Fork; Sag Harbor Cove, in the central part of the South Fork; and West Neck Bay, on Shelter Island.</p><p>Ground-water-flow models were developed, and particle-tracking procedures were applied to the results of each model, to define the flow paths and traveltime of ground water to the three embayments. The steady-state flow models represent the two-dimensional ground-water-flow system along a vertical section through the uplands of each embayment and simulate long-term hydrologic conditions. The particle-tracking procedure used model-generated ground-water levels and flow rates to calculate the water-particle pathlines and times-of-travel through each flow system from the point of entry (recharge) to the point of exit at streams, the shore, or subsea-discharge areas.</p><p>Results for the Meetinghouse Creek study area indicate that about 50 percent of the total recharge that enters the system flows southward to Meetinghouse Creek; half of this amount discharges as base flow to the fresh-water reach of the creek, and half as shoreline underflow to the estuarine reach. About 85 percent of the total discharge to Meetinghouse Creek has flowed entirely within the upper glacial aquifer, and about 15 percent has flowed through the Magothy aquifer. The average age of all ground water discharged to Meetinghouse Creek is about 60 years; the average age of base flow to the freshwater reach of the creek is about 7 years, and the average age of shoreline underflow to the estuarine reach is about 120 years. The results for the Sag Harbor Cove study area indicate that about 30 percent of the total recharge that enters the system flows northward to Sag Harbor Cove; about half of this amount discharges as shoreline underflow, and half as subsea underflow. About 40 percent of the total discharge to Sag Harbor Cove has flowed entirely within the upper glacial aquifer, and about 60 percent has flowed through the Pleistocene marine clay unit, Pleistocene(?) sand unit, or Magothy aquifer. The average age of all ground water discharged to Sag Harbor Cove is about 110 years; the average age of shoreline underflow is about 25 years, and the average age of subsea underflow is about 190 years.</p><p>Results for the West Neck Bay study area indicate that about 65 percent of the total recharge that enters the system flows westward to West Neck Bay; virtually all of this amount discharges as shoreline underflow, but a negligible percentage discharges as subsea underflow. Virtually all discharge to West Neck Bay has flowed entirely within the upper glacial aquifer, although a minor amount has flowed through the Pleistocene marine clay unit. The average age of shoreline underflow to West Neck Bay is about 15 years, and the average age of subsea underflow is about 1,800 years.</p><p>Ground water that discharges to streams and the shores represented in the models is mostly relatively young water that has flowed entirely within the shallow zones of the flow systems, whereas ground water that discharges to the subsea-discharge areas is mostly old water that has flowed through the deep zones. Data obtained from these models allows evaluation of each embayment.s vulnerability to contaminants introduced at the water table and can guide the development of source-area-protection strategies for the corresponding watersheds.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri984181","collaboration":"Prepared in cooperation with the Peconic Estuary Program and Suffolk Department of Health Services","usgsCitation":"Schubert, C., 1999, Ground-water flow paths and traveltime to three small embayments within the Peconic Estuary, eastern Suffolk County, New York: U.S. Geological Survey Water-Resources Investigations Report 98-4181, vi, 41 p., https://doi.org/10.3133/wri984181.","productDescription":"vi, 41 p.","numberOfPages":"47","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":404557,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1998/4181/wri19984181.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":369347,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1998/4181/coverthb.jpg"}],"country":"United States","state":"New York","county":"Suffolk County","otherGeospatial":"Peconic Estuary","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -72.65739440917969,\n              40.91403147143872\n            ],\n            [\n              -72.60520935058594,\n              40.91403147143872\n            ],\n            [\n              -72.60520935058594,\n              40.93426521177941\n            ],\n            [\n              -72.65739440917969,\n              40.93426521177941\n            ],\n            [\n              -72.65739440917969,\n              40.91403147143872\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p>Director, New York Water Science Center<br> U.S. Geological Survey<br>425 Jordan Rd<br> Troy, NY 12180<br> (518) 285-5695 <br> <a href=\"http://ny.water.usgs.gov/\" data-mce-href=\"http://ny.water.usgs.gov/\">http://ny.water.usgs.gov/</a></p>","tableOfContents":"<ul><li>Abstract</li><li>Introduction</li><li>Hydrogeology</li><li>Ground-water flow paths and traveltime to three small embayments within the Peconic Estuary</li><li>Summary and conclusions</li><li>References cited</li></ul>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aabe4b07f02db669b92","contributors":{"authors":[{"text":"Schubert, Christopher 0000-0003-0705-3933 schubert@usgs.gov","orcid":"https://orcid.org/0000-0003-0705-3933","contributorId":1243,"corporation":false,"usgs":true,"family":"Schubert","given":"Christopher","email":"schubert@usgs.gov","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":false,"id":511069,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Analysis of this data can be helpful in displaying any patterns that may be present in introductions of aquatic nuisance species and developing a management plan to prevent spread. To produce maps and perform analysis, all data are referenced geographically at the finest scale possible (state, county, drainage, waterbody, point). Data reported in the literature range from state or regional lists of introduced species to exact time, date, and location of collections or releases. Often, vague locality reports make it difficult to obtain accurate answers in fine-scale analysis.</p>","language":"English","publisher":"National Aquatic Nuisance Species Clearinghouse","usgsCitation":"Fuller, P.L., 1999, USGS develops a drainage-based system to track ANS introductions: Aquatic Nuisance Species Digest, v. 3, no. 3, p. 32-35.","productDescription":"4 p.","startPage":"32","endPage":"35","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":314735,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":314736,"type":{"id":15,"text":"Index Page"},"url":"https://www.anstaskforce.gov/DigestVol3No3.PDF"}],"volume":"3","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56a7556fe4b0b28f1184d8a5","contributors":{"authors":[{"text":"Fuller, Pamela L. 0000-0002-9389-9144 pfuller@usgs.gov","orcid":"https://orcid.org/0000-0002-9389-9144","contributorId":3217,"corporation":false,"usgs":true,"family":"Fuller","given":"Pamela","email":"pfuller@usgs.gov","middleInitial":"L.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":false,"id":589536,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We found more than 51,000 fish of 28 species. Using a model that incorporates annual colony nest counts; fledgling production rates; adult, immature, and young-of-year residence times (seasonal); estimates of mean number of fish per pellet and mean fish size; and a fecal pathway correction factor (4.0 percent), we estimate total annual number of fish consumed by cormorants in the eastern basin of Lake Ontario to range from 37 million to 128 million fish for 1993&ndash;97. This fish loss equates to an estimated 0.93 million to 3.21 million kg (mean 2.07 million kg) of fish consumed per year, principally alewife (<i>Alosa pseudoharengus</i>, 42.3 percent) and yellow perch (<i>Perca flavescens</i>, 18.4 percent). Forage fish (alewife, cyprinids, trout-perch [<i>Percopsis omiscomaycus</i>], and other minor components) accounted for 65 percent of the diet, and panfish contributed 34 percent of the diet for the 5-year period. Game fish were minor components of the diet, in view of an average estimated annual consumption of 900,000 smallmouth bass (<i>Micropterus dolomieui</i>, 1.1 percent) and 168,000 salmonines (mostly lake trout, <i>Salvelinus namaycush</i>, 0.2 percent). Cormorant predation on lake trout fingerlings stocked in May 1993 and June 1994 was estimated through the use of coded wire tag recoveries from pellets collected on Little Galloo Island 1 and 4 days after stocking events. We estimated losses of 13.6 percent and 8.8 percent, respectively, of the fish stocked for the two events, an average of 11.2 percent. Such losses may be reduced through alteration of existing stocking practices.</p>","largerWorkTitle":"Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest","conferenceTitle":"Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest","conferenceDate":"December 9, 1997","conferenceLocation":"Milwaukee, WI","language":"English","publisher":"U.S. Department of Agriculture, Animal and Plant Health Inspection Service","publisherLocation":"Washington, D.C.","usgsCitation":"Ross, R.M., and Johnson, J.H., 1999, Fish losses to double-crested cormorant predation in Eastern Lake Ontario, 1992-97: USDA APHIS Technical Bulletin 1879, 10 p.","productDescription":"10 p.","startPage":"61","endPage":"70","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true},{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":198789,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288448,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.aphis.usda.gov/wildlife_damage/nwrc/symposia/cormorant_symposium/"}],"country":"United States","otherGeospatial":"Lake Ontario;Little Galloo Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.3988896,43.8827599 ], [ -76.3988896,43.8885207 ], [ -76.3923384,43.8885207 ], [ -76.3923384,43.8827599 ], [ -76.3988896,43.8827599 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f3e4b07f02db5efb0b","contributors":{"authors":[{"text":"Ross, Robert M.","contributorId":62562,"corporation":false,"usgs":true,"family":"Ross","given":"Robert","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":325879,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, James H. 0000-0002-5619-3871 jhjohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-5619-3871","contributorId":389,"corporation":false,"usgs":true,"family":"Johnson","given":"James","email":"jhjohnson@usgs.gov","middleInitial":"H.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":325878,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Our objectives for this study were to determine the diet of the cormorant in western Lake Erie and the diet overlap and competition for resources with piscivorous fish, such as walleye (<i>Stizostedion vitreum</i>). The stomach contents of 302 double-crested cormorants collected in western Lake Erie consisted primarily of young-of-the-year gizzard shad (<i>Dorosoma cepedianum</i>), emerald shiner (<i>Notropis atherinoides</i>), and freshwater drum (<i>Aplodinotus grunniens</i>). In the spring, freshwater drum were the most frequently occurring food in the stomachs and constituted the greatest portion of the diet by weight. Young gizzard shad became the most abundant prey and made up the largest percentage of the diet by weight in the stomachs from the end of July through October. Emerald shiners were abundant in the diet during June, September, and October. The fish species that cormorants ate resembled, by proportion, the species mix found in trawl catches. The diets of cormorants and walleyes were similar from July to October with significant overlap. Results from this study suggest impacts of cormorants at current population levels in Lake Erie are not detrimental to sport and commercial fishing. Therefore, control for the purpose of reducing competition for prey fish with walleye is not warranted at this time.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Symposium on double-crested cormorants: Population status and management issues in the Midwest","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Symposium on double-crested cormorants: Population status and management issues in the Midwest","conferenceDate":"December 9, 1997","conferenceLocation":"Milwaukee, WI","language":"English","publisher":"U.S. Department of Agriculture","usgsCitation":"Bur, M.T., Tinnirello, S.L., Lovell, C.D., and Tyson, J.T., 1999, Diet of the double-crested cormorant in western Lake Erie, <i>in</i> Symposium on double-crested cormorants: Population status and management issues in the Midwest, Milwaukee, WI, December 9, 1997, p. 73-85.","productDescription":"12 p.","startPage":"73","endPage":"85","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":198566,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":94613,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://www.aphis.usda.gov/wildlife_damage/nwrc/symposia/cormorant_symposium/pdfs/corsym8_nogfx.pdf"}],"country":"Canada, United States","state":"Ohio, Ontario","otherGeospatial":"Lake Erie, Middle Island, Sandusky Bay, West Sister Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -82.51281738281249,\n              41.918628865183045\n            ],\n            [\n              -82.6171875,\n              42.01665183556825\n            ],\n            [\n              -82.74627685546874,\n              42.01052981889534\n            ],\n            [\n              -82.9193115234375,\n              41.96357478222518\n            ],\n            [\n              -83.056640625,\n              42.01869237684385\n            ],\n            [\n              -83.14727783203125,\n              42.05541092308216\n            ],\n            [\n              -83.199462890625,\n              42.00032514831621\n            ],\n            [\n              -83.25714111328125,\n              41.928846628183166\n            ],\n            [\n              -83.4576416015625,\n              41.73852846935917\n            ],\n            [\n              -83.232421875,\n              41.6770148220322\n            ],\n            [\n              -83.20770263671875,\n              41.65239288426814\n            ],\n            [\n              -83.10333251953125,\n              41.599013054830216\n            ],\n            [\n              -82.99346923828125,\n              41.51886045990478\n            ],\n            [\n              -83.11431884765625,\n              41.45507852101139\n            ],\n            [\n              -83.023681640625,\n              41.393294288784865\n            ],\n            [\n              -82.7325439453125,\n              41.39741506646461\n            ],\n            [\n              -82.59246826171875,\n              41.39741506646461\n            ],\n            [\n              -82.51281738281249,\n              41.918628865183045\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d86e","contributors":{"compilers":[{"text":"Tobin, Mark E.","contributorId":266183,"corporation":false,"usgs":false,"family":"Tobin","given":"Mark","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":824531,"contributorType":{"id":3,"text":"Compilers"},"rank":1}],"authors":[{"text":"Bur, Michael T.","contributorId":102015,"corporation":false,"usgs":true,"family":"Bur","given":"Michael","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":325043,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tinnirello, Sandra L.","contributorId":21251,"corporation":false,"usgs":true,"family":"Tinnirello","given":"Sandra","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":325040,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lovell, Charles D.","contributorId":74481,"corporation":false,"usgs":true,"family":"Lovell","given":"Charles","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":325042,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tyson, Jeff T.","contributorId":68430,"corporation":false,"usgs":true,"family":"Tyson","given":"Jeff","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":325041,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Arc-parallel migration of relatively strong blocks of this terrane, known as Siletzia, focuses upper crustal deformation along block boundaries, which are potential sources of earthquakes. In a three-dimensional velocity model of coastal Washington, we have combined surface geology, well data, and travel times from earthquakes and controlled source seismic experiments to resolve the major boundaries of the Siletz terrane with the adjacent accreted sedimentary prism and volcanic arc. In southern Washington and northern Oregon the Siletz terrane appears to be a thick block (???20 km) that extends west of the coastline and makes a high-angle contact with the offshore accreted sedimentary prism. On its east flank the high-velocity Siletz terrane boundary coincides with an en echelon zone of seismicity in the arc. In northern Washington the western edge of Siletzia makes a lower-angled, fault-bound contact with the accretionary prism. In addition, alternating, east-west trending uplifts and downwarps of the Siletz terrane centered on the antiformal Olympic Mountains may reflect focusing of north-south compression in the northern part of the Siletz terrane. This compressional strain may result from northward transport and clockwise rotation of the Siletz terrane into the relatively fixed Canadian Coast Mountains restraining bend along the coast.","language":"English","publisher":"Wiley","doi":"10.1029/1999JB900106","issn":"01480227","usgsCitation":"Parsons, T., Wells, R., Fisher, M.A., Flueh, E., and ten Brink, U., 1999, Three-dimensional velocity structure of Siletzia and other accreted terranes in the Cascadia forearc of Washington: Journal of Geophysical Research B: Solid Earth, v. 104, no.

Although most families were seen more commonly in coral habitat, they were caught more often in gorgonian areas. Traps probably fished more effectively in gorgonian habitats, especially for migrating species, because traps provided shelter in the relatively topographically uniform environment of gorgonian dominated habitats. Recently, trap fishermen on St. John have been moving effort away from traditionally fished nearshore coral reefs and into a variety of more homogeneous habitats such as gorgonian habitat. Consequently, exploitation rates of the already over-harvested reef fish resources may be increasing.

A stratified, two-stage cluster sample was used to randomly select survey wetlands within strata defined by region, wetland density, and wetland surface area. We used 18-m (0.1 ha) fixed radius circular-plots to survey birds in 412 semipermanent wetlands during the summers of 1995 and 1996. Variation in habitat use by pied-billed grebes (Podilymbus podiceps) and yellow-headed blackbirds (Xanthocephalus xanthocephalus), two sedentary species that rarely exploit resources outside the vicinity of nest wetlands, was explained solely by within-patch variation. Yellow-headed blackbirds were a cosmopolitan species that commonly nested in small wetlands, whereas pied-billed grebes were an area-sensitive species that used larger wetlands regardless of landscape pattern. Area requirements for black terns (Chlidonias niger), a vagile species that typically forages up to 4 km away from the nest wetland, fluctuated in response to landscape structure. Black tern area requirements were small (6.5 ha) in heterogeneous landscapes compared to those in homogeneous landscapes (15.4-32.6 ha). Low wetland density landscapes composed of small wetlands, where few nesting wetlands occurred and potential food sources were spread over large distances, were not widely used by black terns. Landscape-level measurements related to black tern occurrence extended past relationships between wetlands into the surrounding matrix. Black terns were more likely to occur in landscapes where grasslands had not been tilled for agricultural production. Our findings represent empirical evidence that characteristics of entire landscapes, rather than individual patches, must be quantified to assess habitat suitability for wide-ranging species that use resources over large areas.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Landscape Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1008088429081","issn":"09212973","usgsCitation":"Naugle, D., Higgins, K., Nusser, S., and Johnson, W., 1999, Scale-dependent habitat use in three species of prairie wetland birds: Landscape Ecology, v. 14, no. 3, p. 267-276, https://doi.org/10.1023/A:1008088429081.","startPage":"267","endPage":"276","numberOfPages":"10","costCenters":[],"links":[{"id":206403,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1008088429081"},{"id":229638,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b870ee4b08c986b3162a4","contributors":{"authors":[{"text":"Naugle, D.E.","contributorId":85289,"corporation":false,"usgs":true,"family":"Naugle","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":391869,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Higgins, K.F.","contributorId":55767,"corporation":false,"usgs":true,"family":"Higgins","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":391867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nusser, S.M.","contributorId":49302,"corporation":false,"usgs":true,"family":"Nusser","given":"S.M.","email":"","affiliations":[],"preferred":false,"id":391866,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnson, W.C.","contributorId":68003,"corporation":false,"usgs":true,"family":"Johnson","given":"W.C.","email":"","affiliations":[],"preferred":false,"id":391868,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
