This very likely is not true for the 11 species and subspecies of geese that nest in Alaska. Large, widely dispersed populations of geese were observed near the turn of the century. Even in the early 1970s, it was estimated that Alaskan habitats were used by 915,000 nesting and 100,000 additional migrating geese each year (King and Lensink 1971). Since then the Alaskan populations of most of these species have declined, some to dramatically low levels (Raveling 1984), even though habitats within the state have remained largely unaltered by man.</p><p>The U.S. has treaties with Canada, Mexico, Japan and the Soviet Union to protect geese and other shared migratory birds, confirming international concern for the welfare of this resource. Cooperative research on Alaskan geese during the past several decades has given understanding of their migration corridors, staging and wintering habitats, and the principle places where they are hunted, thereby providing information needed to develop effective management plans. The only attempt to re-introduce geese in Alaska has been in the Aleutian Islands.

Three estuarine systems in the Gulf provide critical habitat for migratory shorebirds and waterfowl: 1) the Stikine River Delta, 2) Cook Inlet, and 3) the Copper River Delta. Over 20 million waterbirds are estimated to use the latter system during spring migration. Western sandpipers, dunlin, and northern pintails numerically dominate this migration. Breeding populations of shorebirds and waterfowl in the Gulf are small compared with those elsewhere in Alaska. Of those Gulf regions suitable for nesting waterfowl and shorebirds, the Copper River Delta is the most important. Species diversity and the number of shorebirds wintering in the Gulf are low; however, water- fowl wintering in the Gulf number at least in the low millions. These birds concentrated in sheltered, near-shore regions where their epibenthic and infaunal prey are accessible.</span></p><p>Over nine million seabirds (twenty-six species) nest in the Gulf of Alaska at more than 800 sites. Seabird productivity varies markedly. Food availability seems to have a large influence on reproductive success, especially for surface-feeding species such as the black-legged kittiwake. Seabird densities are highest over shelf and shelf-break habitats during spring migration and in summer. Sooty and short-tailed shearwaters dominate the pelagic avifauna both numerically and in terms of biomass. Seabird densities are generally lower in winter than in summer as a result of both a southward migration of some species and offshore dispersal of others. A variety of prey species are used by seabirds in the Gulf; of these, capelin, sand lance, and euphausiids are of greatest importance. Trophically, seabirds in the Gulf range from near primary con- sumers to third-order carnivores, ingesting an estimated 1,120,000 mt during the 120-day summer period.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"The Gulf of Alaska: Physical environment and biological resources","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"U.S. Department of Commerce","publisherLocation":"Washington, D.C.","usgsCitation":"DeGange, A.R., and Sanger, G.A., 1986, Marine birds, chap. 16 <i>of</i> The Gulf of Alaska: Physical environment and biological resources, p. 479-524.","productDescription":"46 p.","startPage":"479","endPage":"524","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":344036,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","publicComments":"Minerals Management Service publication number: OCS study, MMS 86-0095","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"59706fe0e4b0d1f9f065ab24","contributors":{"editors":[{"text":"Hood, Donald W.","contributorId":111881,"corporation":false,"usgs":false,"family":"Hood","given":"Donald","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":705552,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Zimmerman, Steven T.","contributorId":29325,"corporation":false,"usgs":false,"family":"Zimmerman","given":"Steven","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":705553,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"DeGange, Anthony R. tdegange@usgs.gov","contributorId":139765,"corporation":false,"usgs":true,"family":"DeGange","given":"Anthony","email":"tdegange@usgs.gov","middleInitial":"R.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":705554,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sanger, Gerald A.","contributorId":10660,"corporation":false,"usgs":true,"family":"Sanger","given":"Gerald","email":"","middleInitial":"A.","affiliations":[{"id":6654,"text":"USFWS","active":true,"usgs":false}],"preferred":false,"id":705555,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Characteristics of rocks from these three Klamath Mountains Alaskan-type intrusive suites are (1) Rh contents of near or less than 1 ppb, (2) Ir and Ru contents less than 100 and 20 ppb, (3) variable Pd contents between rock units within intrusive suites and among suites, and (4) relatively similar Pt contents within intrusive suites and among suites. Concentrations of Pd average 6.3 ppb at Lower Coon Mountain, 13.7 ppb at Chanchelulla Peak, and 36.4 ppb at Tincup Peak. Cohen-corrected abundance data for individual rock units within each intrusive suite yield a Pt/(Pt + Pd) ratio that is greater in olivine-rich rocks than in clinopy-roxenite than in gabbro suggesting chemical fractionation of Pd within intrusive suites.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.81.5.1252","issn":"03610128","usgsCitation":"Gray, F., Page, N., Carlson, C., Wilson, S., and Carlson, R.R., 1986, Platinum-group element geochemistry of zoned ultramafic intrusive suites, Klamath Mountains, California and Oregon: Economic Geology, v. 81, no. 5, p. 1252-1260, https://doi.org/10.2113/gsecongeo.81.5.1252.","productDescription":"9 p.","startPage":"1252","endPage":"1260","numberOfPages":"9","costCenters":[],"links":[{"id":225324,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"5","noUsgsAuthors":false,"publicationDate":"1986-08-01","publicationStatus":"PW","scienceBaseUri":"505a7c2ee4b0c8380cd79846","contributors":{"authors":[{"text":"Gray, F.","contributorId":87270,"corporation":false,"usgs":true,"family":"Gray","given":"F.","affiliations":[],"preferred":false,"id":368697,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Page, N.J.","contributorId":38125,"corporation":false,"usgs":true,"family":"Page","given":"N.J.","affiliations":[],"preferred":false,"id":368694,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carlson, C.A.","contributorId":85178,"corporation":false,"usgs":true,"family":"Carlson","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":368696,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wilson, S.

Portions of two Landsat Multispectral Scanner (MSS) scenes and digital terrain data were used to produce 1:250,000 scale land cover and terrain maps. Prints of summer and winter Landsat MSS scenes were used to manually interpret broad physiographic strata. These strata were transferred to U. S. Geological Survey 1:250,000-scale topographic maps and digitized. Seven major land cover classes and 23 subclasses were identified. The major land cover classes include: forest, scrub, dwarf scrub and related types, herbaceous, scarcely vegetated areas, water, and shadow.","largerWorkTitle":"Technical Papers of the American Society of Photogrammetry, Fall Technical Meeting","conferenceTitle":"1986 ASPRS-ACSM Fall Convention - ASPRS Technical Papers.","conferenceLocation":"Anchorage, AK, USA","language":"English","publisher":"American Soc for Photogrammetry & Remote Sensing","publisherLocation":"Falls Church, VA, USA","issn":"02714043","isbn":"0937294764","usgsCitation":"Markon, C.J., and Talbot, S., 1986, Development of labd cover and terrain databases for the Innoko National Wildlife Refuge, Alaska, using LANDSAT and digital terrain data, <i>in</i> Technical Papers of the American Society of Photogrammetry, Fall Technical Meeting, Anchorage, AK, USA, p. 367-368.","startPage":"367","endPage":"368","numberOfPages":"2","costCenters":[],"links":[{"id":224167,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fd44e4b0c8380cd4e721","contributors":{"authors":[{"text":"Markon, Carl J. markon@usgs.gov","contributorId":2499,"corporation":false,"usgs":true,"family":"Markon","given":"Carl","email":"markon@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":false,"id":371453,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Talbot, Stephen S.","contributorId":73266,"corporation":false,"usgs":true,"family":"Talbot","given":"Stephen S.","affiliations":[],"preferred":false,"id":371454,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In addition, this region is flanked by two important oil provinces—the Prudhoe Bay area to the west and the Mackenzie delta to the east. To begin to understand the petroleum resource potential of ANWR, we evaluated the source rock quality and thermal maturity of five rock units ranging in age from Triassic to early Tertiary: Shublik Formation, Kingak Shale, pebble shale unit, Hue Shale and Canning Shale. We also compared ANWR oils using stable carbon isotope ratios, tricyclic terpane ratios, and saturate/aromatic hydrocarbon ratios.</span></p><p><span>The organic carbon content of the five rock units range from an average of 1.6 to 4.0 wt%. Cretaceous rocks from the coastal plain are thermally immature (vitrinite reflectance &lt;0.5%) and in the southern mountains thermally mature to overmature (vitrinite reflectance 1.0–1.8%). In general, type III organic matter predominates in the Kingak Shale, pebble shale unit, and Canning Shale, and types II and III in the Hue Shale.</span></p><p><span>ANWR oils are divided into three groups: (1) Jago oil type, includes oils from Angun Point, Katakturuk River and Jago River; (2) Manning oil type, from Manning Point near the coast of the Beaufort Sea; and (3) Kavik oil type, from Kavik west of the Canning River. None of the three oil types of ANWR compares favorably with the economically important oils from Prudhoe Bay and the National Petroleum Reserve of Alaska (NPRA). The most promising source rock for the otherd ANWR oil types could not be type II units of the Hue Shale. Possible source rocks for the other ANWR oil types could not be established.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0146-6380(86)90040-9","usgsCitation":"Anders, D., and Magoon, L.B., 1986, Oil-source correlation study in northeastern Alaska: Organic Geochemistry, v. 10, no. 1-3, p. 407-415, https://doi.org/10.1016/0146-6380(86)90040-9.","productDescription":"9 p.","startPage":"407","endPage":"415","costCenters":[],"links":[{"id":225651,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"northeastern Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -152.4106716044714,\n              70.64154661082958\n            ],\n            [\n              -152.4106716044714,\n              69.12495942352916\n            ],\n            [\n              -141.0384473873988,\n              69.12495942352916\n            ],\n            [\n              -141.0384473873988,\n              70.64154661082958\n            ],\n            [\n              -152.4106716044714,\n              70.64154661082958\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"10","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6d1be4b0c8380cd74f79","contributors":{"authors":[{"text":"Anders, D.E.","contributorId":28960,"corporation":false,"usgs":true,"family":"Anders","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":368912,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Magoon, Leslie B. lmagoon@usgs.gov","contributorId":2383,"corporation":false,"usgs":true,"family":"Magoon","given":"Leslie","email":"lmagoon@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":368913,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Research was a joint U.S. Fish and Wildlife Service/Alaska Department of Fish and Game effort until passage of the Marine Mammal Protection Act in 1972, and has been largely a Federal effort since then. In 1985, Alaskan polar beer research continues to be carried out by the Research Division of the U.S. Fish and Wildlife Service (DOI).

However, because of problems associated with remoteness and poor weather, little detailed mineral exploration work has been carried on there. This study focuses on using Landsat multispectral scanner data for the Port Moller, Stepovak Bay, and Simeon of Island Quadrangles to detect surface alteration, probably limonitic (iron oxide staining) and(or) argillic (secondary clay minerals) in character, that could be indicative of mineral deposits. The techniques used here are useful for mapping deposits that have exposed surface alteration of at least an hectare, the approximate spatial resolution of the Landsat data. Virtually cloud-free Landsat coverage was used, but to be detected, the alteration area must also be unobscured by vegetation. Not all mineral deposits will be associated with surface alteration, and not all areas of surface alteration will have valuable mineral deposits. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The United States Geological Survey in Alaska: Accomplishments during 1983 (Circular 945)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Alexandria, VA","doi":"10.3133/70180229","usgsCitation":"York, J., Wilson, F.H., and Gamble, B.M., 1985, Digital image processing techniques for detecting surface alteration - An application on the Alaska Peninsula: A section in <i>The United States Geological Survey in Alaska: Accomplishments during 1983</i>: U.S. Geological Survey Circular 945, 3 p., https://doi.org/10.3133/70180229.","productDescription":"3 p.","startPage":"56","endPage":"58","numberOfPages":"3","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":334008,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":333994,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1985/0945/report.pdf#page=68","text":"Start page in larger work"}],"country":"United States","state":"Alaska","otherGeospatial":"Alaska Peninsula","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5889c7c7e4b0ba3b075e064c","contributors":{"authors":[{"text":"York, James","contributorId":69604,"corporation":false,"usgs":true,"family":"York","given":"James","email":"","affiliations":[],"preferred":false,"id":660825,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilson, Frederic H. 0000-0003-1761-6437 fwilson@usgs.gov","orcid":"https://orcid.org/0000-0003-1761-6437","contributorId":67174,"corporation":false,"usgs":true,"family":"Wilson","given":"Frederic","email":"fwilson@usgs.gov","middleInitial":"H.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":660826,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gamble, Bruce M. bgamble@usgs.gov","contributorId":560,"corporation":false,"usgs":true,"family":"Gamble","given":"Bruce","email":"bgamble@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":660827,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Our current data and tentative interpretations are described here, pending completion of additional field research, laboratory, and office studies. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The United States Geological Survey in Alaska: Accomplishments during 1983 (Circular 945)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Alexandria, VA","doi":"10.3133/70180233","usgsCitation":"Wilson, F.H., Case, J.E., and Detterman, R.L., 1985, Preliminary description of a Miocene zone of structural complexity, Port Moller and Stepovak Bay quadrangles, Alaska: A section in <i>The United States Geological Survey in Alaska: Accomplishments during 1983</i>: U.S. Geological Survey Circular 945, 2 p., https://doi.org/10.3133/70180233.","productDescription":"2 p.","startPage":"55","endPage":"56","numberOfPages":"2","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":334006,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1985/0945/report.pdf#page=67","text":"Start page in larger work"},{"id":334007,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Port Moller quadrangle, Stepovak Bay quadrangle","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5889c7bfe4b0ba3b075e063b","contributors":{"authors":[{"text":"Wilson, Frederic H. 0000-0003-1761-6437 fwilson@usgs.gov","orcid":"https://orcid.org/0000-0003-1761-6437","contributorId":67174,"corporation":false,"usgs":true,"family":"Wilson","given":"Frederic","email":"fwilson@usgs.gov","middleInitial":"H.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":660835,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Case, James E.","contributorId":68702,"corporation":false,"usgs":true,"family":"Case","given":"James","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":660836,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Detterman, Robert L.","contributorId":71526,"corporation":false,"usgs":true,"family":"Detterman","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":660837,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Results confirmed that an early run entered the river in May and June and spawned in tributaries, and a late run entered the river from late June through August and spawned in the main stem. Spawning peaked during August in tributaries influenced by lakes, but during July in other tributaries. Lakes may have increased fall and winter temperatures of downstream waters, enabling successful reproduction for later spawning fish within these tributaries. This hypothesis assumes that hatching and emergence can be completed in a shorter time in lake-influenced waters. The time of upstream migration and spawning (mid- to late August) of the late run is unique among chinook stocks in Cook Inlet. This behavior may have developed only because two large lakes (Kenai and Skilak) directly influence the main-stem Kenai River. If run timing is genetically controlled, and if the various components of the two runs are isolated stocks that have adapted to predictable stream temperatures, there are implications for stock transplantation programs and for any activities of man that alter stream temperatures.</span></p>","language":"English","publisher":"Canadian Science Publishing ","doi":"10.1139/f85-089","usgsCitation":"Burger, C.V., Wilmot, R., and Wangaard, D., 1985, Comparisons of spawning areas and times for two runs of chinook salmon (<i>Oncorhynchus tshawytscha</i>) in the Kenai River, Alaska: Canadian Journal of Fisheries and Aquatic Sciences, v. 42, no. 4, p. 693-700, https://doi.org/10.1139/f85-089.","productDescription":"8 p.","startPage":"693","endPage":"700","numberOfPages":"8","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":314320,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Kenai River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -152.38037109375,\n              59.789579955087405\n            ],\n            [\n              -152.38037109375,\n              60.930432202923335\n            ],\n            [\n              -148.02978515625,\n              60.930432202923335\n            ],\n            [\n              -148.02978515625,\n              59.789579955087405\n            ],\n            [\n              -152.38037109375,\n              59.789579955087405\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"42","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5698d4c3e4b0fbd3f7fa4c1e","contributors":{"authors":[{"text":"Burger, C.

The sharp-shinned hawks laid in late May and June. Juvenile females represented 4% of the northern goshawk breeding population; 22% of the Cooper's hawk breeding population (highest reported for the species) and 60% of the sharp-shinned hawk breeding population, northern goshawks and Cooper's hawks in juvenal plumage generally nested later in the season, but not sharp-shinned hawks. Females of each species began molting first. Primaries were molted from the innermost outward in all species, but rectrix molt sequence was variable. Usually R1 was molted first. Primary molt of the 2 wings was usually synchronous; however, the rectrix molt was not as orderly. Arrested molt was observed in some individuals of all species; it probably has an energy-saving function. Wing chords of adult northern goshawks from Oregon were not different from Wisconsin fall migrants or birds from Alaska; however, rectrices were significantly shorter in Oregon than Wisconsin. Cooper's hawks nesting in Oregon were much smaller than those trapped in Wisconsin. Wing chords and rectrices were significantly shorter for both sexes, and, although weights were not directly comparable, Oregon Cooper's hawks also weighed much less. The limited number of sharp-shinned hawks measured precluded statistical analyses.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Field Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Henny, C.J., Olson, R., and Fleming, T., 1985, Breeding chronology, molt, and measurements of accipiter hawks in northeastern Oregon: Journal of Field Ornithology, v. 56, no. 2, p. 97-112.","productDescription":"97-112","startPage":"97","endPage":"112","numberOfPages":"16","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":18559,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/JFO/v056n02/p0097-p0112.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":196428,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"56","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e499fe4b07f02db5bd32b","contributors":{"authors":[{"text":"Henny, Charles J.","contributorId":12578,"corporation":false,"usgs":true,"family":"Henny","given":"Charles","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":335296,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Olson, R.A.","contributorId":82417,"corporation":false,"usgs":true,"family":"Olson","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":335297,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fleming, T.L.","contributorId":107008,"corporation":false,"usgs":true,"family":"Fleming","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":335298,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Prior to this study we had obtained only addled eggs which were possibly not representative of the egg-laying population if addled eggs contained different levels of organochlorines than viable eggs that hatched. Ten eggs were collected from the American (anatum) population (8 upper Yukon River, 2 Tanana River) and 10 eggs from the Arctic (tundrius) popUlation were later collected in the study area. Productivity at specific eyries and eggshell thickness were evaluated in relation to residue burdens in sample eggs collected. Residue levels and residue profiles for the two subspecies were compared. The tentative 'critical' residue level in Peregrine eggs of 15-20 ppm DDE (wet weight) was compared to results obtained from this study. We also present some data on residue levels in prey species from the study area.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Raptor Research Foundation Symposium on the Management of Birds of Prey.
