Distributions of laying or hatching observed in 11 species during 1–7 years are presented; less detailed information is available on the breeding schedules of three species. The combined laying period of 14 species lasted 3 months from mid-April to mid-July; the first eggs of the earliest and latest species were laid about 9 weeks apart. Mean laying dates varied by 2–16 days in nine species observed in 2 or more years. Although the egg-laying sequence of species was largely preserved from year to year, we found little evidence of concordant annual variation in breeding seasons. Species that fed lower in the food chain tended to breed earlier than those that fed at higher trophic levels. Early laying was correlated with longer laying periods, both within and between species. With the exception of three puffin species, birds with similar food habits exhibited less overlap in hatching and fledging dates than laying dates. A test for nonrandom dispersion of breeding times failed to find evidence for competitive avoidance of breeding overlap in piscivores or planktivores. Species may not have timed their egg laying to provide for maximum food availability during chick rearing. Rather, the comparative analysis of breeding schedules suggests that breeding times were determined more by the food requirements of laying females. Young females laying relatively late probably account for the right-skewed distributions of egg laying observed in this and other studies of colonial seabirds.</span></p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/z90-247","usgsCitation":"Hatch, S.A., and Hatch, M.A., 1990, Breeding seasons of oceanic birds in a subarctic colony: Canadian Journal of Zoology, v. 68, no. 8, p. 1664-1679, https://doi.org/10.1139/z90-247.","productDescription":"16 p.","startPage":"1664","endPage":"1679","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":335371,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Gulf of Alaska, Semidi Islands","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -157.00836181640625,\n              55.91535151540654\n            ],\n            [\n              -156.4617919921875,\n              55.91535151540654\n            ],\n            [\n              -156.4617919921875,\n              56.315013425566924\n            ],\n            [\n              -157.00836181640625,\n              56.315013425566924\n            ],\n            [\n              -157.00836181640625,\n              55.91535151540654\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"68","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a4254ae4b0c825128ad4d5","contributors":{"authors":[{"text":"Hatch, Scott A. 0000-0002-0064-8187 shatch@usgs.gov","orcid":"https://orcid.org/0000-0002-0064-8187","contributorId":2625,"corporation":false,"usgs":true,"family":"Hatch","given":"Scott","email":"shatch@usgs.gov","middleInitial":"A.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":668698,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hatch, Martha A.","contributorId":181576,"corporation":false,"usgs":false,"family":"Hatch","given":"Martha","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":668699,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The annual rate of mortality of immatures during the first year was 77 per cent. Annual mortality rates of adults ranged from 35 to 50 per cent. Mortality rates of females were higher than those of males. Relatively larger numbers of immatures and adult females were shot early in the hunting season, and relatively larger numbers of males were shot late in the hunting season. Hunting was estimated to account each year for more than one-half the deaths of canvasbacks of flying age. Comparisons of band-recovery rates in years of different hunting regulations showed that both season length and daily bag limit affected the hunting kill.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Studies in Avian Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Burger, A., and Piatt, J.F., 1990, Flexible time budgets in breeding Common Murres: Buffers against variable prey availability: Studies in Avian Biology, v. 14, p. 71-83.","productDescription":"pp. 71-83","startPage":"71","endPage":"83","numberOfPages":"13","costCenters":[{"id":106,"text":"Alaska Biological Science Center","active":false,"usgs":true}],"links":[{"id":131669,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae69a","contributors":{"authors":[{"text":"Burger, A.E.","contributorId":56605,"corporation":false,"usgs":true,"family":"Burger","given":"A.E.","email":"","affiliations":[],"preferred":false,"id":318513,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Piatt, John F. 0000-0002-4417-5748 jpiatt@usgs.gov","orcid":"https://orcid.org/0000-0002-4417-5748","contributorId":3025,"corporation":false,"usgs":true,"family":"Piatt","given":"John","email":"jpiatt@usgs.gov","middleInitial":"F.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":318514,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The study area, which covered 10% (300 km</span><sup>2</sup><span>) of the delta's intertidal flats, regularly hosted 17 species of shorebirds between late April and mid-October. The greatest use was during the postbreeding period (late June-October), when Dunlins (<i>Calidris alpina</i>), Western Sandpipers (<i>C. mauri</i>), and Rock Sandpipers (<i>C. ptilocnemis</i>), each with large local nesting populations, accounted for 95% of the shorebirds recorded. Peak counts during autumn approached 300,000 birds. Considering the seasonal occurrence and turnover of populations, we estimate 1-2 million shorebirds use the central delta each year. The delta supports large fractions of the Pacific Rim or world populations of Bar-tailed Godwits (<i>Limosa lapponica</i>), Black Turnstones (<i>Arenaria</i> <i>melanocephala</i>), Red Knots (<i>C. canutus</i>), Western Sandpipers, Dunlins, and Rock Sandpipers.

Hazen Bay frequently hosted more than 1,200 shorebirds/km</span><sup>2</sup><span>. Postbreeding shorebirds used intertidal habitats in three distinct patterns according to age class. For most species (n = 7), there was a period when adults appeared first, followed by a brief interval when adults and juveniles mixed, then by a prolonged period when only juveniles remained. In the second pattern (n = 3 species), adults moved onto the intertidal flats first, were later joined by juveniles for a prolonged staging period, then migrated with them. In the third pattern (n = 3 species), only juveniles used the delta's intertidal habitat. Temporal segregation among species and age groups may minimize competition for food and thereby allow the delta to support high diversity and numbers of shorebirds.</span></p>","language":"English","publisher":"Cooper Ornithological Society","doi":"10.2307/1368690","usgsCitation":"Gill, R., and Handel, C.M., 1990, The importance of subarctic intertidal habitats to shorebirds: A study of the central Yukon-Kuskokwim Delta, Alaska: The Condor, v. 92, no. 3, p. 709-725, https://doi.org/10.2307/1368690.","productDescription":"17 p.","startPage":"709","endPage":"725","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":335810,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Yukon-Kuskokwim Delta","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -166.7669677734375,\n              60.764525674175374\n            ],\n            [\n              -164.410400390625,\n              60.764525674175374\n            ],\n            [\n              -164.410400390625,\n              61.825040379926115\n            ],\n            [\n              -166.7669677734375,\n              61.825040379926115\n            ],\n            [\n              -166.7669677734375,\n              60.764525674175374\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"92","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a819b9e4b025c46429afec","contributors":{"authors":[{"text":"Gill, Robert E.

Murres and puffins foraged offshore prior to the arrival inshore of spawning schools of capelin. Both species were abundant during peak periods of capelin abundance from late June to late July, but only puffins continued to forage inshore after capelin schools dispersed in August. On individual surveys, murre and puffin flocks were significantly correlated with capelin schools at fine and coarse spatial scales. Aggregation intensity and spatial correlations peaked at measurement intervals of 2-6 km. At that scale, murres and puffins exhibited sigmoidal (Type III) aggregative responses to capelin schools. Inflection points (thresholds) in sigmoidal aggregative response curves occurred at higher densities of capelin for murres than for puffins and foraging thresholds for both species varied daily with overall capelin abundance in Witless Bay. Murres probably foraged on denser schools of capelin than puffins because of their larger body size and associated higher food demands. The implications of differing foraging thresholds for population ecology of alcids are discussed.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Auks at sea: Proceedings of an International Symposium of the Pacific Seabird Group (Studies in Avian Biology no.14)","largerWorkSubtype":{"id":15,"text":"Monograph"},"conferenceTitle":"An International Symposium of the Pacific Seabird Group","conferenceDate":"December 17, 1987","conferenceLocation":"Pacific Grove, CA","language":"English","publisher":"Cooper Ornithological Society","isbn":"0935868496","usgsCitation":"Piatt, J.F., 1990, The aggregative response of common murres and Atlantic puffins to schools of capelin, chap. <i>of</i> Auks at sea: Proceedings of an International Symposium of the Pacific Seabird Group (Studies in Avian Biology no.14): Studies in Avian Biology, v. 14, p. 36-51.","productDescription":"16 p.","startPage":"36","endPage":"51","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337536,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337534,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.americanornithology.org/content/studies-avian-biology","text":"<i>Studies in Avian Biology</i> Homepage"}],"country":"Canada","state":"Newfoundland","otherGeospatial":"Witless Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -52.96783447265625,\n              47.0439255239614\n            ],\n            [\n              -52.625885009765625,\n              47.0439255239614\n            ],\n            [\n              -52.625885009765625,\n              47.338822694822\n            ],\n            [\n              -52.96783447265625,\n              47.338822694822\n            ],\n            [\n              -52.96783447265625,\n              47.0439255239614\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"14","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c90130e4b0849ce97abd63","contributors":{"editors":[{"text":"Sealy, Spencer G.","contributorId":111386,"corporation":false,"usgs":true,"family":"Sealy","given":"Spencer","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":684303,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Piatt, John F. 0000-0002-4417-5748 jpiatt@usgs.gov","orcid":"https://orcid.org/0000-0002-4417-5748","contributorId":3025,"corporation":false,"usgs":true,"family":"Piatt","given":"John","email":"jpiatt@usgs.gov","middleInitial":"F.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":684305,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The first technique regressed survival of nests or eggs during a time interval against interval length. Departure of the y-intercept from 1.0 estimated the short-term effect of the visit at the beginning of the interval. The y-intercepts (±95% CI) for whole nests and eggs during the egg laying period were 1.11 ± 0.31 and 1.06 ± 0.31, respectively. During incubation the same 2 parameters were 0.66 ± 0.31 and 0.66 ± 0.33. The regression method was, thus, imprecise and failed to discriminate among widely varying potential impacts of visitors. The second method involved visiting nests and then immediately revisiting them after pairs had returned to their territories. This method estimated loss of eggs as a result of displacement of territorial pairs during the first visit. Only 1 of 50 eggs was lost (n = 27 nests) as a result of visits during egg laying, whereas no eggs were lost (n = 225 eggs and 55 nests) owing to visits during the incubation period. I conclude that the regression approach is an imprecise tool for estimating visitor impact, but results from both methods indicate little effect of nest visitation under conditions existing on the colony I studied.</span></p>","language":"English","publisher":"Wiley","doi":"10.2307/3809655","usgsCitation":"Sedinger, J.S., 1990, Effects of visiting black brant nests on egg and nest survival: Journal of Wildlife Management, v. 54, no. 3, p. 437-443, https://doi.org/10.2307/3809655.","productDescription":"7 p.","startPage":"437","endPage":"443","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":336896,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Tutakoke River, Yukon-Kuskokwim Delta","volume":"54","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58be8341e4b014cc3a3a9a2d","contributors":{"authors":[{"text":"Sedinger, James S.","contributorId":84861,"corporation":false,"usgs":false,"family":"Sedinger","given":"James","email":"","middleInitial":"S.","affiliations":[{"id":12742,"text":"University of Nevada Reno","active":true,"usgs":false}],"preferred":false,"id":680845,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

I hypothesize that the lower population equilibrium is achieved largely or exclusively on an invertebrate diet consisting principally of herbivorous sea urchins. When unregulated by sea otter predation, the rocky benthos is deforested by sea urchin grazing. As growing otter populations compete increasingly for food, grazing intensity declines and the system shifts to one dominated by kelp beds, in turn leading to increased production, a shift in habitat structure, and population increases of kelp bed fishes. Apparently this new food resource elevates the sea otter population to a higher and more stable equilibrium.</span></p>","language":"English","publisher":"British Ecological Society","doi":"10.2307/4870","usgsCitation":"Estes, J.A., 1990, Growth and equilibrium in sea otter populations: Journal of Animal Ecology, v. 59, p. 385-400, https://doi.org/10.2307/4870.","productDescription":"16 p.","startPage":"385","endPage":"400","numberOfPages":"16","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":129970,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"59","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a8fe4b07f02db654b75","contributors":{"authors":[{"text":"Estes, J.

Because of their unique phenocryst content-biotite in rare amounts and a high proportion of amphibole to pyroxene-the deposits are readily identifiable at all but the most distant sites where they are very fine grained. Eighteen radiocarbon dates from eight upland sites limit the age of the tephra set to between about 3500 and 3800 yr. The set originated at Hayes volcano in the Tordrillo Mountains 150 km northwest of Anchorage; seven or possibly eight closely succeeding deposits, low-silica dacite in composition, compose two main lobes that extend northeast for 400 km and south for at least 250 km from the vent. We estimate the total tephra volume to be 10 km3; multiple layers imply four to six larger and two or three smaller eruptions. The deposits are a nearly isochronous marker horizon that should be useful in future archeologic, geologic, and palynologic studies in the region. ?? 1990.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(90)90056-Q","issn":"00335894","usgsCitation":"Riehle, J., Bowers, P., and Ager, T.A., 1990, The Hayes tephra deposits, and upper Holocene marker horizon in south-central Alaska: Quaternary Research, v. 33, no. 3, p. 276-290, https://doi.org/10.1016/0033-5894(90)90056-Q.","startPage":"276","endPage":"290","numberOfPages":"15","costCenters":[],"links":[{"id":222790,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266503,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(90)90056-Q"}],"volume":"33","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505ba770e4b08c986b321572","contributors":{"authors":[{"text":"Riehle, J.R.","contributorId":73573,"corporation":false,"usgs":true,"family":"Riehle","given":"J.R.","affiliations":[],"preferred":false,"id":372924,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bowers, P.M.","contributorId":60094,"corporation":false,"usgs":true,"family":"Bowers","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":372923,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ager, T.

The primary objective of this operation was to capture live, oiled sea otters for cleaning and rehabilitation. Between 30 March and 29 May 1989, 139 live sea otters were captured in the sound and transported to rehabilitation centers in Valdez, Alaska. Within the first 15 days of capture operations, 122 (88%) otters were captured. Most sea otters were captured near Knight, Green, and Evans islands in the western sound. The primary capture method consisted of dipnetting otters out of water and off beaches. While capture rates declined over time, survival of captured otters increased as the interval from spill date to capture date increased. The relative degree of oiling observed for each otter captured declined over time. Declining capture rates led to the use of tangle nets. The evidence suggests the greatest threat to sea otters in Prince William Sound occurred within the first 3 weeks after the spill. Thus, in the future, the authors believe rescue efforts should begin as soon as possible after an oil spill in sea otter habitat. Further, preemptive capture and relocation of sea otters in Prince William Sound may have increased the number of otters that could have survived this event.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Sea otter symposium: Proceedings of a symposium to evaluate the response effort on behalf of sea otters after the T/V <i>Exxon Valdez</i> oil spill into Prince William Sound (Biological Reports 90[12])","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"conferenceTitle":"Sea Otter Symposium: Symposium to evaluate the response effort on behalf of sea otters after the T/V <i>Exxon Valdez</i> oil spill into Prince William Sound","conferenceDate":"April 17-19, 1990","conferenceLocation":"Anchorage, AK","language":"English","publisher":"U.S. Fish and Wildlife Service","publisherLocation":"Anchorage, AK","doi":"10.5962/bhl.title.45854","issn":"0895-1926","usgsCitation":"Bodkin, J.L., and Weltz, F., 1990, Evaluation of sea otter capture after the Exxon Valdez oil spill, Prince William Sound, Alaska, <i>in</i> Sea otter symposium: Proceedings of a symposium to evaluate the response effort on behalf of sea otters after the T/V <i>Exxon Valdez</i> oil spill into Prince William Sound (Biological Reports 90[12]), Anchorage, AK, April 17-19, 1990, p. 61-69, https://doi.org/10.5962/bhl.title.45854.","productDescription":"9 p.","startPage":"61","endPage":"69","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":488641,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5962/bhl.title.45854","text":"Publisher Index Page"},{"id":343082,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Prince William Sound","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5965f9c5e4b0d1f9f05cae6c","contributors":{"editors":[{"text":"Bayha, Keith","contributorId":30270,"corporation":false,"usgs":false,"family":"Bayha","given":"Keith","email":"","affiliations":[{"id":6654,"text":"USFWS","active":true,"usgs":false}],"preferred":false,"id":702307,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Kormendy, Jennifer","contributorId":190781,"corporation":false,"usgs":false,"family":"Kormendy","given":"Jennifer","email":"","affiliations":[],"preferred":false,"id":702308,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Bodkin, James L. 0000-0003-1641-4438 jbodkin@usgs.gov","orcid":"https://orcid.org/0000-0003-1641-4438","contributorId":748,"corporation":false,"usgs":true,"family":"Bodkin","given":"James","email":"jbodkin@usgs.gov","middleInitial":"L.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":702305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weltz, F.","contributorId":100704,"corporation":false,"usgs":false,"family":"Weltz","given":"F.","email":"","affiliations":[],"preferred":false,"id":702306,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The igneous protolith of this gneiss was a suite of subduction-related platonic rocks. U-Pb data on zircons from trondhjemitic and granitic samples yield upper-intercept (igneous) ages of 2070 ±16 and 2040 ±74 Ma, respectively. Nd isotope data from these rocks suggest that a diorite-tonalite-trondhjemite suite (ε<sub>Nd</sub><span>&nbsp;</span>[T] = +2.1 to +2.7; T is time of crystallization) evolved from partial melts of depleted mantle with no discernible contamination by older crust, whereas a coeval granitic pluton (ε<sub>Nd</sub><span>&nbsp;</span>[T] = -5.7) contains a significant component derived from Archean crust. Orthogneisses with similar age and Nd isotope characteristics are found in the Idono complex 250 km to the north. Early Proterozoic rocks are unknown elsewhere in Alaska. However, Phanerozoic plutons cutting several \"continental\" terranes in Alaska (southern Brooks Range and Ruby, Seward, and Yukon-Tanana terranes) have Nd isotope compositions indicative of Early Proterozoic (or older) crustal components that could be correlative with rocks of the Kilbuck terrane. Rocks with similar igneous ages in cratonal North America are rare, and those few that are known have Nd isotope compositions distinct from those of the Kilbuck terrane. Conversely, provinces with Nd model ages off 2.0-2.1 Ga are characterized by extensive 1.8 Ga or younger plutonism, which is unknown in the Kilbuck terrane. At present the case for a North American parentage of the Kilbuck terrane is not compelling. The possibility that the Kilbuck terrane was displaced from provinces off similar age in other cratons (e.g., Australian, Baltic, Guiana, and west African shields), or from the poorly dated Siberian craton, cannot be excluded.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1990)018<1219:KTOKRI>2.3.CO;2","issn":"00917613","usgsCitation":"Box, S.E., Moll-Stalcup, E.J., Wooden, J.L., and Bradshaw, J., 1990, Kilbuck terrane: Oldest known rocks in Alaska: Geology, v. 18, no. 12, p. 1219-1222, https://doi.org/10.1130/0091-7613(1990)018<1219:KTOKRI>2.3.CO;2.","productDescription":"4 p.","startPage":"1219","endPage":"1222","numberOfPages":"4","costCenters":[],"links":[{"id":223236,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4092e4b0c8380cd64e7a","contributors":{"authors":[{"text":"Box, S.

This climatic change resulted from interaction of the Yakutat terrane with southern Alaska beginning in late Oligocene time. The ensuing extreme uplift of the coastal Chugach and St. Elias Mountains resulted in progressive regional cooling that culminated in coastal marine glaciation beginning in the early middle Miocene (15-16 Ma) and continuing to the present. The counterclockwise flow of surface water from the frigid northeastern Gulf of Alaska resulted in a cold-temperate shallow-marine environment in the western Gulf of Alaska, as it does today. Ironically, dating of Gulf of Alaska marine glaciation as early middle Miocene is strongly reinforced by the presence of a few tropical and subtropical mollusks in western Gulf of Alaska faunas.

Except for laying dates, there was little evidence that individual differences in these attributes contributed to variation in breeding success. A test of breeding experience as a contributing factor revealed an interaction between individual and annual components of variation. During years when the whole population did relatively poorly, pairs with no previous breeding experience were affected disproportionately.

Reliability of the entire system was generally high. Data were received from instrumented caribou (<i>Rangifer tarandus</i>) during 91% of 318 possible transmitter-months. Transmitters failed prematurely on 5 of 45 caribou, 2 of 6 muskoxen (<i>Ovibos moschatus</i>), and 1 of 2 gray wolves (<i>Canis lupus</i>). Failure rates were considerably higher for polar (<i>Ursus maritimus</i>) and brown (<i>U. arctos</i>) bears than for caribou (<i>Rangifer tarandus</i>). Efficiency of gathering both locational and sensor data was related to both latitude and topography.</p><p>Mean error of locations was estimated to be 954 m (median = 543 m) for transmitters on captive animals; 90% of locations were &lt;1,732 m from the true location. Argos's new location class zero processing provided many more locations than normal processing, but mean location error was much higher than locations estimated normally. Locations were biased when animals were at elevations other than those used in Argos's calculations.</p><p>Long-term and short-term indices of animal activity were developed and evaluated. For several species, the long-term index was correlated with movement patterns and the short-term index was calibrated to specific activity categories (e.g., lying, feeding, walking).</p><p>Data processing and sampling considerations were evaluated.
