Of the 120 lake trout used in the experiment, 40 were fed a low ration (0.25% of their body weight per day), 40 were fed a medium ration (0.5% of their body weight per day), and 40 were fed a high ration (ad libitum). We measured consumption and growth, and we compared observed consumption with that predicted by the Wisconsin bioenergetics model. For lake trout fed the medium ration, model predictions for monthly consumption were unbiased. Moreover, predicted cumulative consumption by medium-ration lake trout for the entire experiment (320 d for smaller lake trout and 407 d for larger lake trout) agreed quite well with observed cumulative consumption; predictions were as close as within 0.1 to 5.2% of observed cumulative consumption. Even so, the model consistently overestimated consumption by low-ration fish and underestimated consumption by high-ration fish. The bias was significant in both cases, but was more severe for the low-ration trout. Because the low-ration and high-ration regimes were probably unrealistic for lake trout residing in Lake Michigan and because the model fit our laboratory data rather well for medium-ration trout, we conclude that applying the Wisconsin bioenergetics model to the Lake Michigan lake trout population in order to estimate the amount of prey fish consumed by lake trout each year is appropriate.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1577/1548-8659(1999)128<0802:LEOALT>2.0.CO;2","usgsCitation":"Madenjian, C.P., and O’Connor, D.V., 1999, Laboratory evaluation of a lake trout bioenergetics model: Transactions of the American Fisheries Society, v. 128, no. 5, p. 802-814, https://doi.org/10.1577/1548-8659(1999)128<0802:LEOALT>2.0.CO;2.","productDescription":"13 p.","startPage":"802","endPage":"814","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":479613,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1577/1548-8659(1999)128<0802:leoalt>2.0.co;2","text":"Publisher Index Page"},{"id":133608,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"128","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db6998e8","contributors":{"authors":[{"text":"Madenjian, Charles P. 0000-0002-0326-164X cmadenjian@usgs.gov","orcid":"https://orcid.org/0000-0002-0326-164X","contributorId":2200,"corporation":false,"usgs":true,"family":"Madenjian","given":"Charles","email":"cmadenjian@usgs.gov","middleInitial":"P.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":310208,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Connor, Daniel V.","contributorId":73950,"corporation":false,"usgs":true,"family":"O’Connor","given":"Daniel","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":310209,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We measured sediment and water variables in 32 pairs of wetlands with and without a current outbreak of avian botulism. Wetlands with botulism outbreaks had greater percent organic matter (POM) in the sediment (P = 0.088) and lower redox potential in the water (P = 0.096) than paired control wetlands. We also found that pH, redox potential, temperature, and salinity measured just above the sediment-water interface were associated (P ≤ 0.05) with the risk of botulism outbreaks in wetlands, but relations were complex, involving nonlinear and multivariate associations. Regression models indicated that the risk of botulism outbreaks increased when water pH was between 7.5 and 9.0, redox potential was negative, and water temperature was >20°C. Risk declined when redox potential increased (>100), water temperature decreased (10-15°C), pH was <7.5 or >9.0, or salinity was low (<2.0 ppt). Our predictive models could allow managers to assess potential effects of wetland management practices on the risk of botulism outbreaks and to develop and evaluate alternative management strategies to reduce losses from avian botulism.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.2307/3802842","issn":"0022541X","usgsCitation":"Rocke, T.E., and Samuel, M.D., 1999, Water and sediment characteristics associated with avian botulism outbreaks in wetlands: Journal of Wildlife Management, v. 63, no. 4, p. 1249-1260, https://doi.org/10.2307/3802842.","productDescription":"12 p.","startPage":"1249","endPage":"1260","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":230101,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288514,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/3802842"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.98046874999999,\n              25.64152637306577\n            ],\n            [\n              -124.98046874999999,\n              49.32512199104001\n            ],\n            [\n              -86.748046875,\n              49.32512199104001\n            ],\n            [\n              -86.748046875,\n              25.64152637306577\n            ],\n            [\n              -124.98046874999999,\n              25.64152637306577\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"63","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc7a4e4b08c986b32c565","contributors":{"authors":[{"text":"Rocke, Tonie E. 0000-0003-3933-1563 trocke@usgs.gov","orcid":"https://orcid.org/0000-0003-3933-1563","contributorId":2665,"corporation":false,"usgs":true,"family":"Rocke","given":"Tonie","email":"trocke@usgs.gov","middleInitial":"E.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":389246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Samuel, Michael D. msamuel@usgs.gov","contributorId":1419,"corporation":false,"usgs":true,"family":"Samuel","given":"Michael","email":"msamuel@usgs.gov","middleInitial":"D.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":389245,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Textural evidence and radiometric dates imply ore formation during sedimentation of black shales that grade into readily combustible beds, termed stone coals, which contain 10 to 15 percent organic carbon. Studies of 427 fluid inclusions indicate extreme variation in hydrothermal brine salinities that were contained by Proterozoic dolostones underlying the ore zone in Hunan and Guizhou. Variations of fluid inclusion salinities, which range from 0.1 to 21.6 wt percent NaCl equiv, are attributed to differences in the compositions of brines in strata underlying the ore bed, complicated by the presence of sea-water and dilute fluids that represent condensates of vapors generated by boiling of mineralizing fluids or Cambrian meteoric water. The complex processes of ore deposition led to scattered homogenization temperatures ranging from 100 degrees to 187 degrees C within the Hunan ore zone and from 65 degrees to 183 degrees C within the Guizhou ore zone. While living organisms probably did not directly accumulate metals in situ in sufficient amounts to explain the unusually high grades of the deposits, sulfur isotope ratios indicate that bacteria, now preserved as abundant microfossils, provided sufficient sulfide for the ores by reduction of seawater sulfate. Such microbiota may have depended on vent fluids and transported organic matter for key nutrients and are consistent with a sedex origin for the ores. Vent fluids interacted with organic remains, including rounded fragments of microbial mats that were likely transported to the site of ore deposition by the action of waves and bottom currents prior to replacement by ore minerals.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.94.7.1051","issn":"03610128","usgsCitation":"Lott, D., Coveney, R., Murowchick, J., and Grauch, R., 1999, Sedimentary exhalative nickel-molybdenum ores in south China: Economic Geology, v. 94, no. 7, p. 1051-1066, https://doi.org/10.2113/gsecongeo.94.7.1051.","productDescription":"16 p.","startPage":"1051","endPage":"1066","numberOfPages":"16","costCenters":[],"links":[{"id":229816,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"7","noUsgsAuthors":false,"publicationDate":"1999-11-01","publicationStatus":"PW","scienceBaseUri":"505b8a1de4b08c986b317041","contributors":{"authors":[{"text":"Lott, D.A.","contributorId":70138,"corporation":false,"usgs":true,"family":"Lott","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":388861,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coveney, R.M.

In the subfamily Anserinae, however, reproduction normally does not commence until individuals reach two to four years of age (Rohwer 1992). Most published accounts indicate that Canada Geese (<i>Branta canadensis</i>) conform to the pattern typically found in other geese, deferring reproduction as yearlings and initiating breeding when birds are two years of age or older (Hanson 1962, Brakhage 1965, Bellrose 1980, Moser and Rusch 1989). The few documented exceptions (Brakhage 1965, Cooper 1978, MacInnes and Dunn 1988) suggest that the likelihood of a successful breeding attempt is higher for yearling males than females and that when early breeding occurs, one member of the pair is often at least two years old.

The same areas are utilized from year to year. Habitat factors important in spawning site determination include gravel/cobble substrate, the presence of eddy fields, a neutral to slightly alkaline pH, and an empirically observed range in calcium ion content (6-18 mg/L Ca++, corresponding to a conductivity range of 40-110??S). Eggs are deposited contagiously within a small area (< 10,000 m2) with very little scatter, suggesting little if any current drift. They are not found from samplers on immediately adjacent sand substrate. The broadcast spawner model does not seem to fit the Gulf sturgeon. Spawning begins 4-7 days after the March new moon, with water temperature above 17.0 oC, and extends for 9-23 days as discrete events involving individual females. Spawning may continue, if water temperature remains below 21-22oC. The total annual pool of spawning females in the Suwannee population is estimated at 80 individuals. Young of the year utilize open sand habitat away from shoreline and vegetated habitat. They disperse widely, and occur over freshwater reaches from rkm 10-237; no particular affinity with spring water habitat is evident. Larger Gulf sturgeon tend to congregate in deep holes serving as summer-fall holding areas. They fast and lose weight while remaining in freshwater, but more than compensate this loss during winter feeding in marine waters. The major downriver migration to the estuary takes place in October-November. After a period of river mouth staging, subadults and adults migrate into Gulf of Mexico nearshore mesohaline waters. They move further out and into deeper water (> 3 m) when water temperatures drop in mid-December, but final destinations in mid-winter remain unknown. Age-2 through 6 juveniles remain in the river mouth estuary over winter. In late January through early February YOY migrate downriver for the first time, joining larger juveniles to overwinter and feed. Tag and recapture data yield a Suwannee River population of Gulf sturgeon estimated at 7,650 individuals, with an annual turnover rate of 16%. Based on stability in cumulative recapture rates from 1991-1998, population size is stable with an effective balance between recruitment and mortality. However, population structure is dynamic, controlled by the juxtaposition, conjunction, and summation of successive strong and weak year classes. Length/age frequency distributions for 1995 and 1998 populations censuses are very different. The 1995 distribution is bimodal with a dominant mode of 9-14 year old subadults/adults, and a sub-dominant of mode of 2-4 year old juveniles. The 1998 distribution is trimodal, but overwhelmingly dominated by 6-9 year old subadults. Erosion by 1998 of the major subadult/adult mode from the 1995 census illustrates that large adults encounter the same high mortality as smaller fish. Ultimate adult size in the population has remained constant at 2.2 cm TL over 13 years, indicating a maximum life expectancy of 25 years for Suwannee River Gulf sturgeon.","largerWorkTitle":"Journal of Applied Ichthyology","language":"English","issn":"01758659","usgsCitation":"Sulak, K., and Clugston, J.P., 1999, Recent advances in life history of Gulf of Mexico sturgeon, Acipenser oxyrinchus desotoi, in the Suwannee River, Florida, USA: A synopsis, <i>in</i> Journal of Applied Ichthyology, v. 15, no. 4-5, p. 116-128.","startPage":"116","endPage":"128","numberOfPages":"13","costCenters":[],"links":[{"id":229864,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"4-5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a95dbe4b0c8380cd81c8d","contributors":{"authors":[{"text":"Sulak, K.

Body mass of captive chicks closely fit a Gompertz growth curve, revealing a growth coefficient (K) of 0.065 day-1 and point of inflection (T) of 17 days. When chicks fledged about 28 days after hatching, they weighed only 60% of adult body mass; at 42 d, birds still were only 75% of adult mass; culmen, tarsus, and wing chord at fledging also were less than adult size. This trend of continued growth to adult size after fledging is typical for most shorebirds. After hatching, captive chicks grew more rapidly than wild chicks, probably because of an unlimited food supply. We found no evidence for adverse effects of weather on the growth of wild chicks. As with other shorebirds, the tarsus started relatively long, with culmen and then wing chord growing more rapidly in later development. Tarsal and wing chord growth were sigmoidal, whereas culmen growth was linear. We describe plumage characteristics of weekly age classes of chicks to help researchers age birds in the wild.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00435643","usgsCitation":"Reed, J., Gray, E., Lewis, D., Oring, L., Coleman, R., Burr, T., and Luscomb, P., 1999, Growth patterns of Hawaiian Stilt chicks: The Wilson Bulletin, v. 111, no. 4, p. 478-487.","startPage":"478","endPage":"487","numberOfPages":"10","costCenters":[],"links":[{"id":229970,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"111","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2dfee4b0c8380cd5c1ef","contributors":{"authors":[{"text":"Reed, J.M.","contributorId":66441,"corporation":false,"usgs":true,"family":"Reed","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":388314,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gray, E.M.","contributorId":62781,"corporation":false,"usgs":true,"family":"Gray","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":388313,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lewis, D.","contributorId":7444,"corporation":false,"usgs":true,"family":"Lewis","given":"D.","affiliations":[],"preferred":false,"id":388310,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Oring, L.W.","contributorId":46451,"corporation":false,"usgs":true,"family":"Oring","given":"L.W.","affiliations":[],"preferred":false,"id":388311,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Coleman, R.","contributorId":47520,"corporation":false,"usgs":true,"family":"Coleman","given":"R.","affiliations":[],"preferred":false,"id":388312,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Burr, T.","contributorId":88062,"corporation":false,"usgs":true,"family":"Burr","given":"T.","email":"","affiliations":[],"preferred":false,"id":388315,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Luscomb, P.","contributorId":106278,"corporation":false,"usgs":true,"family":"Luscomb","given":"P.","affiliations":[],"preferred":false,"id":388316,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Traditional suture and epoxy attachment methods were used on Xantus' Murrelets in 1995 and 1996, while the modified attachment was used for Xantus' Murrelets in 1996 and 1997 and Marbled Murrelets in 1997. Modifications included use of an inhalant anesthetic, placing the anchor in a more cranial position on the back, application of marine epoxy, and place- ment of a single subcutaneous non-absorbable suture at the caudal end of the radio to hold the radio in place initially. We located 22 of 56 (39%) Xantus' Murrelets radio-marked using suture and epoxy during aerial surveys in 1995 and 1996. Of birds radio-marked using the subcutaneous anchor attachment, we located 92 of 113 (81%) Xantus' Murrelets marked in 1996 and 1997 and all 28 (100%) Marbled Murrelets marked in 1997 during aerial surveys. The maximum confirmed duration for the subcutaneous anchor transmitter attachment was 51 d for Xantus' Murrelets and 78 d for Marbled Murrelets versus 41 d for the suture and epoxy attachment used on Xantus' Murrelets. Recapture rates of radio-marked Xantus' Mur- relets were similar to recapture rates of unmarked Xantus' Murrelets. Our post-release ob- servations indicated negligible short-term physical effects from the attachment procedure, while telemetry data and examination of recaptured murrelets indicated no evidence of infection or other long-term physical effects. Breeding behavior of some murrelets was not disrupted; however, further evaluation of potential effects of this attachment technique on breeding and behavior is needed.</p>","language":"English","publisher":"Association of Field Ornithologists","usgsCitation":"Newman, S.H., Takekawa, J.Y., Whitworth, D.L., and Burkett, E.E., 1999, Subcutaneous anchor attachment increases retention of radio transmitters on Xantus' and marbled murrelets: Journal of Field Ornithology, v. 70, no. 4, p. 520-534.","productDescription":"15 p.","startPage":"520","endPage":"534","numberOfPages":"15","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":132428,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"70","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699c18","contributors":{"authors":[{"text":"Newman, Scott H.","contributorId":101372,"corporation":false,"usgs":true,"family":"Newman","given":"Scott","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":316874,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":316876,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Whitworth, Darrell L.","contributorId":87338,"corporation":false,"usgs":true,"family":"Whitworth","given":"Darrell","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":316873,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Burkett, Esther E.","contributorId":174939,"corporation":false,"usgs":false,"family":"Burkett","given":"Esther","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":316875,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Multivariate analyses of over 2770 data points revealed two principal components that accounted for 68% of the total variance in the data. These two components, the first highly loaded with Al, B, Cr, Fe, Ni and S, and the second loaded with Ca, Cd, Mg and Mn, were inversely related to each other over time and space. The first component was interpreted as consisting of an anthropogenic and a dust component, while the second, primarily a nutritional component. Cu, K, Na, P, Pb and Zn were not highly loaded on either component. Component 1 decreased significantly over the 11 years and from west to east, while component 2 increased. The corticolous species were more enriched in heavy metals than the terricolous species. All four elements in component 2 in&nbsp;</span><i>H. physodes</i><span>&nbsp;were above enrichment thresholds for this species. Species differences on the two components were greater than the effects of time and space, suggesting that biomonitoring with lichens is strongly species dependent.

Using historical presence-absence data and our own surveys, we estimated annual rates of extirpation and recolonization for several populations of the goby in southern California. As predicted, large wetlands had lower rates of extirpation than small wetlands. There was a negative but statistically nonsignificant correlation between recolonization rate and distance to the nearest northerly source population. Populations at small sites were sensitive to drought, presumably because droughts can eliminate suitable habitat at small wetlands. Populations in small wetlands have declined over time, even after accounting for variation in stream flow, supporting the species' endangered status. Our study emphasizes the need to understand metapopulation dynamics for conserving species where the unit of conservation is a local population. It is also emphasizes the importance of not treating metapopulations as identical units. Finally, our results provide a means for describing the decline of a species that is complex in time and space and provide insight into how to target protection measures among metapopulations.</span></p>","language":"English","publisher":"Wiley","doi":"10.1046/j.1523-1739.1999.98016.x","usgsCitation":"Lafferty, K.D., Swift, C.C., and Ambrose, R., 1999, Extirpation and recolonization in a metapopulation of an endangered fish, the tidewater goby: Conservation Biology, v. 13, no. 6, p. 1447-1453, https://doi.org/10.1046/j.1523-1739.1999.98016.x.","productDescription":"7 p.","startPage":"1447","endPage":"1453","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":133043,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.84007578952105,\n              32.57924476677657\n            ],\n            [\n              -116.96859290621114,\n              33.24075348004719\n            ],\n            [\n              -118.0297649285373,\n              34.11421833298377\n            ],\n            [\n              -119.05410356414626,\n              34.5338721202251\n            ],\n            [\n              -120.12101381986645,\n              34.76917764913648\n            ],\n            [\n              -120.20219438421546,\n              35.16659016418255\n            ],\n            [\n              -121.07599484497754,\n              36.02845303621187\n            ],\n            [\n              -121.6354341058834,\n              38.16422902780312\n            ],\n            [\n              -122.3981789694547,\n              38.434933644254215\n            ],\n            [\n              -123.36080658853393,\n              39.17619113934646\n            ],\n            [\n              -123.98139751267314,\n              40.37136935641254\n            ],\n            [\n              -123.8467885261226,\n              40.91508584238656\n            ],\n            [\n              -123.96761370207025,\n              41.95991868581393\n            ],\n            [\n              -124.47348385165589,\n              41.98724150893901\n            ],\n            [\n              -124.47216483234348,\n              41.70381314727467\n            ],\n            [\n              -124.21092423616233,\n              41.472849420179216\n            ],\n            [\n              -124.37505381529593,\n              41.06653501247189\n            ],\n            [\n              -124.29113245581368,\n              40.801972476798255\n            ],\n            [\n              -124.63565850688349,\n              40.42329582286797\n            ],\n            [\n              -124.41220721902226,\n              39.98823275527138\n            ],\n            [\n              -124.04726119915574,\n              39.81818992963812\n            ],\n            [\n              -123.85219440855528,\n              38.79382355220321\n            ],\n            [\n              -123.01339370442031,\n              38.15341002111387\n            ],\n            [\n              -122.78075902644554,\n              37.65332235589496\n            ],\n            [\n              -122.5793237268943,\n              37.04833412258513\n            ],\n            [\n              -122.1358022802284,\n              36.781868180427026\n            ],\n            [\n              -122.08660337061005,\n              36.17503883867465\n            ],\n            [\n              -121.7093039552148,\n              35.94813482346983\n            ],\n            [\n              -121.07276574634142,\n              35.260458363338856\n            ],\n            [\n              -120.77565795628794,\n              35.03006704802192\n            ],\n            [\n              -120.82794538929824,\n              34.39554374126949\n            ],\n            [\n              -120.42631931235516,\n              33.885994415581365\n            ],\n            [\n              -119.48793760208446,\n              33.0822245601931\n            ],\n            [\n              -118.40372845798737,\n              32.746383125290876\n            ],\n            [\n              -116.84007578952105,\n              32.57924476677657\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"13","issue":"6","noUsgsAuthors":false,"publicationDate":"2001-12-24","publicationStatus":"PW","scienceBaseUri":"4f4e4a06e4b07f02db5f8a3d","contributors":{"authors":[{"text":"Lafferty, K.

However, analysis of the California Statewide Fire History Database shows that, since 1910, fire frequency and area burned have not declined, and fire size has not increased. Fire rotation intervals have declined, and fire season has not changed, implying that fire intensity has not increased. Fire frequency and population density were correlated, and it is suggested that fire suppression plays a critical role in offsetting potential impacts of increased ignitions. Large fires were not dependent on old age classes of fuels, and it is thus unlikely that age class manipulation of fuels can prevent large fires.

Ma. The weighted mean of the U/Pb model ages is 1.18 ?? 0.03 Ma. The U-Pb ages coincide closely with 40Ar/39Ar age spectrum plateau and 'terminal' ages from coexisting K-feldspars and with the eruption ages of overlying volcanic rocks. The data indicate that the granite crystallized at 1.18 Ma and had cooled below 350??C by ~0.9-1.0 Ma. Interpretation of the feldspar 40Ar/39Ar age data using multi-diffusion domain theory indicates that post-emplacement rapid cooling was succeeded either by slower cooling from 350??to 300??C between 1.0 and 0.4 Ma or transitory reheating to 300-350??C at about 0.4-0.6 Ma. Subsequent rapid cooling to below 260??C between 0.4 and 0.2 Ma is in agreement with previous proposals that vapor-dominated conditions were initiated within the hydrothermal system at this time. Heat flow calculations constrained with K-feldspar thermal histories and the present elevated regional heat flow anomaly demonstrate that appreciable heat input from sources external to the known Geysers plutonic complex is required to maintain the geothermal system. This requirement is satisfied by either a large, underlying, convecting magma chamber (now solidified) emplaced at 1.2 Ma or episodic intrusion of smaller bodies from 1.2 to 0.6 Ma.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earth and Planetary Science Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0012-821X(99)00223-X","issn":"0012821X","usgsCitation":"Dalrymple, G.B., Grove, M., Lovera, O., Harrison, T., Hulen, J.B., and Lanphere, M.A., 1999, Age and thermal history of the Geysers plutonic complex (felsite unit), Geysers geothermal field, California: A 40Ar/39Ar and U-Pb study: Earth and Planetary Science Letters, v. 173, no. 3, p. 285-298, https://doi.org/10.1016/S0012-821X(99)00223-X.","startPage":"285","endPage":"298","numberOfPages":"14","costCenters":[],"links":[{"id":229704,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206423,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0012-821X(99)00223-X"}],"volume":"173","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e8e4e4b0c8380cd47f55","contributors":{"authors":[{"text":"Dalrymple, G.

The deposit, southernmost of four recently mined gold deposits in the Carolina slate belt, is located in the Lincolnton-McCormick district of Georgia and South Carolina, which includes several known gold-silver and base metal deposits in a Kuroko-type geological setting along with deposits of kyanite and manganese. Approximately 1,835,000 g of gold was produced mainly from oxidized ores in the Main and Rainsford pits from 1990 until their closing in 1994. Ore is hosted by sericitically altered felsic metavolcanic and metasedimentary rocks of the Late Proterozoic Persimmon Fork Formation. The deposit is stratigraphically below an overturned contact between upper and lower pyroclastic units, which overlie the Lincolnton metarhyolite, an intrusive unit. Gold-silver-rich zones in the Main pit are partly coincident with lenses of siliceous barite rock, but not confined to them, and occur more commonly in pyrite-quartz-altered fragmental rock. The Main pit ore is stratigraphically overlain by a zone of base metal and barite enrichment, which is, in turn, overlain by a talc-tremolite alteration zone locally. Siliceous barite zones are absent in the Rainsford pit, and gold-silver minerals are associated with silicified rocks and chert. The Barite Hill deposit is interpreted to be the result of Kuroko-type, volcanogenic, base metal sulfide mineralization, followed by gold-silver mineralization under epithermal conditions with the following stages of evolution: (1) massive sulfides, barite, and fine-grained siliceous exhalites were deposited during Late Proterozoic to Cambrian submarine volcanism, which was related to plate convergence and subduction in a microcontinental or island-arc setting distant from the North American continental plate; (2) Au-Ag-Te and base and precious metal Te-Se-Bi minerals were deposited either during waning stages of hydrothermal activity in a failed massive sulfide system or in a separate event; (3) sulfides and silica-barite rock recrystallized during regional deformation and greenschist facies metamorphism related to the Middle to Late Ordovician collision of the Carolina terrane with the North American continental plate; (4) quartz, barite, and gold were remobilized and formed veins that cut across cleavage; (5) orebodies were offset along high-angle faults; and (6) during weathering, base metal sulfides and barite dissolved and reprecipitated as supergene euhedral barite crystals that line ferric iron oxide-hydroxide gossans.","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.94.8.1329","issn":"03610128","usgsCitation":"Clark, S.H., Gray, K.J., and Back, J.M., 1999, Geology of the Barite Hill gold-silver deposit in the southern Carolina slate belt: Economic Geology, v. 94, no. 8, p. 1329-1346, https://doi.org/10.2113/gsecongeo.94.8.1329.","productDescription":"18 p.","startPage":"1329","endPage":"1346","numberOfPages":"18","costCenters":[],"links":[{"id":229928,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"8","noUsgsAuthors":false,"publicationDate":"1999-12-01","publicationStatus":"PW","scienceBaseUri":"505a2506e4b0c8380cd5859e","contributors":{"authors":[{"text":"Clark, Sandra H.

The hole was drilled about 100 m (meters) south of the southwest corner of a commercial burial site for low-level radioactive wastes in September 1993. UZB-2 is equipped with ten 2.5-cm (centimeters) diameter air ports permanently installed in the unsaturated zone between the depths of 5.5 and 108.8 m below land surface. Depth to ground water is about 110 m. Additional sampling ports were driven by hand to depths of 0.5, 1.0 and 1.5 m in May 1997. Initial samples of water vapor collected in April 1994 showed elevated tritium concentrations of more than 100 TU (tritium units) from all 10 air ports, with a maximum concentration of 762±10 TU from an air port at a depth of 24.1 m. Subsequent tritium concentrations increased in all air ports, although tritium concentrations at depths of less than 34.1 m have remained relatively constant since July 1995. The largest observed increase in tritium has been at a depth of 47.9 m. There, tritium concentration has increased from 198±5 TU in April 1994 to 2,570±30 TU in June 1998. Large increases also have been measured in samples collected from air ports at depths of 106.4 and 108.8 m, just above the water table.</p><p>During September and October 1998, carbon dioxide samples were collected from all ten air ports in UZB-2 and at a depth of 1.5 m, and analyzed for radioactive carbon-14 (<sup>14</sup>C).<span>&nbsp;</span><sup>14</sup>C concentrations are highest in air ports at depths less than 6 m where they exceed 2,000 pmc (percent modern carbon).

Yet, in the past century, many populations have been greatly diminished and some are now extinct-the result of a combination of factors, including habitat loss and degradation, overfishing, natural variability in salmon production, negative effects of artificial propagation, and weaknesses in institutional and regulatory structures. We argue that a major shift is required, from the egocentric environmental approach (wherein each part of the ecosystem is managed as a unit) to the ecocentric ecosystem approach (wherein all parts are integrated for management). A management framework is proposed that contains-for each management unit such as a watershed-four elements: management goals; management objectives, ecosystem indicators; and a coordinated action plan. We also describe the Sustainable Fisheries Strategy, a consultative process for developing an ecosystem-based approach toward achieving sustainable Pacific salmon and steelhead populations and fisheries. This book is one of three important underpinnings of the Strategy; the other two are the Strategy itself and a manual being developed to guide community-based programs embracing the principles of sustainable fisheries. This book contains important historical perspectives as well as numerous innovative ideas for moving toward ecosystem-oriented, sustainable management of Pacific salmon and steelhead.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Sustainable fisheries management: Pacific salmon","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"CRC Press","doi":"10.1201/9781439822678.sec1","isbn":"978-1-4398-2267-8","usgsCitation":"MacDonald, D.D., Steward, C.R., and Knudsen, E.E., 1999, Setting the stage for a sustainable Pacific salmon fisheries strategy, chap. 1 <i>of</i> Sustainable fisheries management: Pacific salmon, p. 3-13, https://doi.org/10.1201/9781439822678.sec1.","productDescription":"11 p","startPage":"3","endPage":"13","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":339196,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2009-12-16","publicationStatus":"PW","scienceBaseUri":"58e60276e4b09da6799ac69d","contributors":{"editors":[{"text":"Knudsen, E.

To determine wetland attributes associated with outbreaks of avian botulism in waterbirds at the Sacramento National Wildlife Refuge (SNWR), California, we compared environmental characteristics between wetlands where outbreaks occurred (outbreak wetlands) and did not occur (nonoutbreak wetlands). In June through October, 1987 89, we monitored the occurrence of avian botulism via observations for sick or dead sentinel mallards (Anas platyrhynchos) placed in 4 wetland enclosures. During this same time period, we collected environmental data from the water column and sediments of each wetland enclosure at 10 14-day sampling intervals. Multivariate analysis was used to reduce 22 environmental variables to 7 factors for inclusion in subsequent statistical analyses. We found that outbreak wetlands had significantly lower redox potential than nonoutbreak wetlands. The probability of botulism in sentinel mallards was associated with increasing temperature, increasing invertebrate abundance or biomass, and decreasing turbidity. However, because these factors were not consistently higher in outbreak wetlands compared to nonoutbreak wetlands, they may have a more proximate effect in initiating an outbreak.</p>","language":"English","publisher":"Wildlife Society","doi":"10.2307/3802520","usgsCitation":"Rocke, T.E., Euliss, N.H., and Samuel, M.D., 1999, Environmental characteristics associated with the occurrence of avian botulism in wetlands of a northern California refuge: Journal of Wildlife Management, v. 63, no. 1, p. 358-368, https://doi.org/10.2307/3802520.","productDescription":"11 p.","startPage":"358","endPage":"368","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true},{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":128541,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"Willows","otherGeospatial":"Sacremento National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.20333099365234,\n              39.35155583694644\n            ],\n            [\n              -122.20333099365234,\n              39.4637641090409\n            ],\n            [\n              -122.07767486572266,\n              39.4637641090409\n            ],\n            [\n              -122.07767486572266,\n              39.35155583694644\n            ],\n            [\n              -122.20333099365234,\n              39.35155583694644\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"63","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a14e4b07f02db6024c7","contributors":{"authors":[{"text":"Rocke, Tonie E. 0000-0003-3933-1563 trocke@usgs.gov","orcid":"https://orcid.org/0000-0003-3933-1563","contributorId":2665,"corporation":false,"usgs":true,"family":"Rocke","given":"Tonie","email":"trocke@usgs.gov","middleInitial":"E.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":312033,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Euliss, Ned H.

Profiles of oxygen-18 (<span size=\"-2\"><sup>18</sup></span>O), deuterium (D), and tritium (<sup><span size=\"-2\">3</span></sup>H) from a 110-meter deep unsaturated zone, together with data on the isotopic composition of ground water and modern-day precipitation, are interpreted in the context of water-content, water-potential, and pore-gas profiles. At depths greater than about three meters, water vapor and liquid water are in approximate equilibrium with respect to D and <span size=\"-2\"><sup>18</sup></span>O. The vapor-phase concentrations of D and <span size=\"-2\"><sup>18</sup></span>O have remained stable through repeated samplings. Vapor-phase <sup><span size=\"-2\">3</span></sup>H concentrations have generally increased with time, requiring synchronous sampling of liquid and vapor to assess equilibrium. Below 30 meters, concentrations of D and <span size=\"-2\"><sup>18</sup></span>O in pore water become approximately equal to the composition of ground water, which is isotopically lighter than modern precipitation and has a carbon-14 (<span size=\"-2\"><sup>14</sup></span>C) concentration of about 26 percent modern carbon. These data indicate that net gradients driving fluxes of water, gas, and heat are directed upwards for undisturbed conditions at the Amargosa Desert Research Site (ADRS).
