I report here a correlation of climatic change with fluctuations in the sizes of litters of grizzly bears born in Yellowstone National Park, Wyoming, during 1958&ndash;1976. The decrease in litter sizes observed since the closure of garbage dumps seems to be largely a consequence of unfavourable weather during the periods of the final fattening of the mother, winter sleep, birth, lactation and early spring foraging.

Runoff processes","docAbstract":"<p>Combined use of radioisotope tracer, flow rate, specific conductance and suspended-sediment measurements on a large field plot near Stanford, California, has provided more detailed information on surface and subsurface storm runoff processes than would be possible from any single approach used in isolation. Although the plot was surficially uniform, the runoff processes were shown to be grossly nonuniform, both spatially over the plot, and laterally and vertically within the soil. The three types of processes that have been suggested as sources of storm runoff (Horton-type surface runoff, saturated overland flow, and rapid subsurface throughflow) all occurred on the plot. The nonuniformity of the processes supports the partial- and variable-source area concepts. Subsurface storm runoff occurred in a saturated layer above the subsoil horizon, and short travel times resulted from flow through macropores rather than the soil matrix. Consideration of these observations would be necessary for physically realistic modeling of the storm runoff process.&nbsp;</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0022-1694(78)90077-X","issn":"00221694","usgsCitation":"Pilgrim, D., Huff, D., and Steele, T., 1978, A field evaluation of subsurface and surface runoff.

Field-collectible scats were distinguished from liquid, non-collectible stools. I n collectible scats, the remains of small prey occurred in greater proportion relative to the prey's weight, and in lesser proportion relative to the prey's numbers, than did the remains of larger prey.

This variable was found to be more sensitive to lead than previous tests that have been employed with waterfowl (Locke et al. 1966, 1967), and has proved to be completely reliable (Finley et al. 1976a,b). However, it is not yet known how long ALAD enzyme inhibition persists after a source of high head contamination is removed. The duration of inhibition is critical because too brief a response would result in underestimating the extent of lead contamination in a given year's survey. Moreover, the ALAD enzyme bioassay can be used to identify ducks that have ingested lead shot, as well as those that have ingested low levels of lead in their forage, and this information used to help remove the source of the environmental contamination.</p>","language":"English","doi":"10.2307/3800826","usgsCitation":"Dieter, M.P., and Finley, M.T., 1978, Erythrocyte δ-Aminolevulinic Acid

The lack of agreement between results of the floating dome method and the other methods was attributed to limitations in instrument accuracy amplified by physical relationships of the dome to the water column rather than conceptual errors in the dome method. In techniques where polarographic oxygen probes are used to monitor the oxygen content within the dome atmosphere, the ratio of volume of the dome to volume of the water column under the dome must be kept below 0.02 to minimize instrument error to less than 10 percent of the predicted oxygen transport. The combination of instrument limitations, coupled with environmental limitations caused by wind and the greenhouse effects, severely restrict application of the floating dome method.</p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Stephens, D.W., 1978, Preliminary evaluation of the floating dome method of measuring reaeration rates: Journal of Research of the U.S. Geological Survey, v. 6, no. 4, p. 547-552.","productDescription":"6 p.","startPage":"547","endPage":"552","costCenters":[],"links":[{"id":403175,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":403174,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1978/vol6issue4/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"6","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Stephens, Doyle W.","contributorId":40195,"corporation":false,"usgs":true,"family":"Stephens","given":"Doyle","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":846013,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

A model is proposed in which uranium mobility is controlled by two competing processes. Uranium is liberated from the volcanic rocks through dissolution of the glassy constituents and is carried in solution as a uranyl carbonate complex. Uranium is subsequently removed from solution by adsorption on secondary oxides of iron, titanium, and manganese, as observed in fission-track maps of aquifer rocks. The model explains the poor correlation of dissolved uranium with depth within tuffaceous sequences in which percolation of ground water is predominantly downward. Good positive correlation of dissolved uranium with dissolved Na, total dissolved solids, and total carbonate supports the glass dissolution model, while inverse correlation of dissolved uranium with U<sup>234</sup>/U<sup>238</sup> ratios of waters implies uranium is being absorbed by a relatively insoluble, surficial phase.

Reduced sandstone is characterized in many deposits by the presence of iron sulflde minerals (particularly marcasite and pyrite) that occur as replacements of and overgrowths on iron-titanium oxide minerals and plant debris and as cement of detrital grains. Oxidation of the sulfldes by oxygenated ground water forms yellow to red ferric oxide and ferric hydroxide phases (\"limonite\") that replace the FeS<sub>2</sub> minerals. Processes other than the oxidation of sulfldes, however, can cause reddening of clastic sediments without the creation of a redox boundary, and so color alone is not a sufficient condition by which to judge the potential for uranium ore in frontier areas. Ferric oxides that form by the oxidation of iron sulflde minerals can be distinguished from other forms of ferric oxide by reflection microscopic examination of polished grain mounts- and polished thin sections'. Diagnostic features of oxidized sulfldes are limonite pseudomorphs of sulfldes and limonite containing internal textures that mimic characteristic textures of previously sulfldized detrital phases. Recognition of oxidized sulfides by reflection microscopy, then, can distinguish oxidized sandstones, which might have a redox boundary downdip and which would therefore be favorable hosts for uranium concentration, from those without such potential. </p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Reynolds, R.L., and Goldhaber, M.B., 1978, Recognition of oxidized sulfide minerals as an exploration guide for uranium: Journal of Research of the U.S. Geological Survey, v. 6, no. 4, p. 483-488.","productDescription":"6 p.","startPage":"483","endPage":"488","costCenters":[],"links":[{"id":403152,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":403151,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1978/vol6issue4/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"6","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":139068,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":845998,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goldhaber, Martin B. 0000-0002-1785-4243 mgold@usgs.gov","orcid":"https://orcid.org/0000-0002-1785-4243","contributorId":1339,"corporation":false,"usgs":true,"family":"Goldhaber","given":"Martin","email":"mgold@usgs.gov","middleInitial":"B.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":845999,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This erionite is in a welded tuff interbedded with lacustrine rocks- of a closed Pliocene basin. The zeolites, chabazite, erionite, clinoptilolite, and other authigenic silicate minerals are confined to a 27-square-kilometer area of altered rocks enclosed in relatively freshwater lacustrine beds. About 135 meters of the lower part of the 350-m stratigraphic section at the southeastern part of the lake basin contain zeolitic tuff. The chabazite is an early product of the reaction between glass of rhyolitic or dacitic composition and alkaline (pH&gt;9) saline lake waters. Erionite, clinoptilolite, analcime, and potassium feldspar follow chabazite in the paragenetic sequence. At the erionite type locality, chabazite and clinoptilolite form megascopic crystal clusters within fractures and cavities in unaltered welded tuff. Elsewhere in the basin, most zeolite crystals in the altered airfall or reworked tuffs are less than 80 micrometers long. Chemical analyses, unit-cell determinations, and mean indices of refraction show that fine-grained chabazite varies in composition and physical parameters. </p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Gude, A.J., and Sheppard, R.A., 1978, Chabazite in siliceous tuffs of a Pliocene lacustrine deposit near Durkee, Baker County, Oregon: Journal of Research of the U.S. Geological Survey, v. 6, no. 4, p. 467-472.","productDescription":"6 p.","startPage":"467","endPage":"472","costCenters":[],"links":[{"id":403148,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":403147,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1978/vol6issue4/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Oregon","county":"Baker County","city":"Durkee","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.50461578369139,\n              44.54742015866826\n            ],\n            [\n              -117.4167251586914,\n              44.54742015866826\n            ],\n            [\n              -117.4167251586914,\n              44.61979915773973\n            ],\n            [\n              -117.50461578369139,\n              44.61979915773973\n            ],\n            [\n              -117.50461578369139,\n              44.54742015866826\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"6","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Gude, Arthur J. 3rd 3rd","contributorId":34932,"corporation":false,"usgs":true,"family":"Gude","given":"Arthur","suffix":"3rd","email":"","middleInitial":"J. 3rd","affiliations":[],"preferred":false,"id":845994,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sheppard, Richard A.","contributorId":41815,"corporation":false,"usgs":true,"family":"Sheppard","given":"Richard","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":845995,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The type locality originally designated for the Rosalie Granite was in a pluton (later called the Rosalie lobe) 10 kilometers southeast of Rosalie Peak on Deer and Elk Creeks. The name \"Rosalie Granite\" was abandoned by T. S. Levering in 1929 because the granite of the Rosalie lobe is actually the distinctly younger Pikes Peak Granite, only 1,030 m.y. (million years) old, whereas the \"Rosalie Granite\" between Mount Evans and Rosalie Peak is a felsic phase of the l,700-m.y.-old Mount Evans pluton. In addition, the Rosalie Granite has more MgO and Sr and less Na<sub>2</sub>O, F, and Rb than the Pikes Peak Granite, and the two granites differ petrographically. In order to avoid confusion in correlation, the name Rosalie should not be applied to rocks in this area.
