Eggs were deposited in the stream channel in June and hatched in November and December. Embryonic development occurred in 47-92% of eggs from unmated females. With rising water levels following snowmelt in March or April, nymphs moved from channel to floodplain, where most nymphal growth and development took place. Sex ratios of nymphs in the floodplain were female biased (1 M:1.4 F in 1991 and 1 M:2.1 F in 1992). Nymphs molted to the final instar earlier in 1991 than in 1992 and male nymphs molted to the final instar before female nymphs in 1991 but not 1992. Time in the final instar decreased as the season advanced. Seasonal emergence was protandrous and lasted 10-11 d during late May and early June; timing of seasonal emergence in 1991, 1992, and 1993 was related to maximum air temperatures and persistence of standing water in the floodplain during May. Emergence of subimagos was female biased in 1991, but male biased in 1992. Diel emergence was from 0700 to 1700 h (EST) and occurred only when water temperature was &gt;11°C.</p></div></div></div></div>","language":"English","publisher":"University of Chicago Press","doi":"10.2307/1467435","issn":"08873593","usgsCitation":"Gibbs, K., and Siebenmann, M., 1996, Life history attributes of the rare mayfly Siphlonisca aerodromia Needham (Ephemeroptera:Siphlonuridae): Journal of the North American Benthological Society, v. 15, no. 1, p. 95-105, https://doi.org/10.2307/1467435.","productDescription":"11 p.","startPage":"95","endPage":"105","numberOfPages":"11","costCenters":[],"links":[{"id":227338,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a475ce4b0c8380cd6783a","contributors":{"authors":[{"text":"Gibbs, K.E.","contributorId":96371,"corporation":false,"usgs":true,"family":"Gibbs","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":379547,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Siebenmann, M.","contributorId":37090,"corporation":false,"usgs":true,"family":"Siebenmann","given":"M.","email":"","affiliations":[],"preferred":false,"id":379546,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Its detailed osteological description presented here provides a number of interesting characters, some not previously reported for the genus. This specimen (BYU 9047) was earlier named Cathetosaurus lewisi, n. gen. et sp., based on seven characters cited by Jensen (1988). Of these characters, four appear to be age related (this skeleton represents a very old individual) and not of taxonomic significance. Nevertheless, they are useful in advancing our understanding of the ligamentation associated with the sacral and posterior dorsal regions, not only of Camarasaurus but of the sauropods in general. These characters also contribute to a greater knowledge of the ontogenetic development and fusion of the sacral elements. Camarasaurus lewisi (Jensen, 1988) is a valid species whose diagnostic characters include (1) a deep but narrow cleft in the neural spines of presacral vertebrae, which most significantly persists to the sacrum rather than ending in the mid-dorsal region, as in all other species of Camarasaurus; (2) a forward rotation of the ilium with respect to the long axis of the sacrum, a hitherto unreported major character of the genus Camarasaurus; and (3) a steep angle that the posterior chevron articulating facets make with the horizontal plane.","language":"English","publisher":"Brigham Young University","issn":"00681016","usgsCitation":"Mcintosh, J., Miller, W., Stadtman, K., and Gillette, D., 1996, The osteology of Camarasaurus lewisi (Jensen, 1988): Brigham Young University Geology Studies, v. 41, p. 73-95.","productDescription":"23 p.","startPage":"73","endPage":"95","numberOfPages":"23","costCenters":[],"links":[{"id":228528,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bae73e4b08c986b3240e7","contributors":{"authors":[{"text":"Mcintosh, J.S.","contributorId":51931,"corporation":false,"usgs":true,"family":"Mcintosh","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":377489,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, W.E.","contributorId":24118,"corporation":false,"usgs":true,"family":"Miller","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":377487,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stadtman, K.L.","contributorId":22516,"corporation":false,"usgs":true,"family":"Stadtman","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":377486,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gillette, D.D.","contributorId":34283,"corporation":false,"usgs":true,"family":"Gillette","given":"D.D.","email":"","affiliations":[],"preferred":false,"id":377488,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Intrastratal deformation is easily confused with buried slump or slide deposits formed initially at the sea floor.

Three new potassium-argon ages range from 23.9 ?? 1.0 Ma to 22.6 ?? 1.2 Ma. The rocks are similar in composition, stratigraphic character, and age to the Blawn Formation, which is found in ranges to the east and southeast in Utah, and, therefore, are herein established as a western extension of the Blawn Formation. Miocene volcanism in the northern Wilson Creek Range began with the eruption of two geochemically similar, weakly evolved ash-flow tuff cooling units. The lower unit consists of crystal-poor, loosely welded, lapilli ash-flow tuffs, herein called the tuff member of Atlanta Summit. The upper unit consists of homogeneous, crystal-rich, moderately to densely welded ash-flow tuffs, herein called the tuff member of Rosencrans Peak. This unit is as much as 300 m thick and has a minimum eruptive volume of 6.5 km3, which is unusually voluminous for tuffs in the Blawn Formation. Thick, conspicuously flow-layered rhyolite lava flows were erupted penecontemporaneously with the tuffs. The rhyolite lava flows have a range of incompatible trace element concentrations, and some of them show an unusual mixing of aphyric and porphyritic magma. Small volumes of alkaline, vesicular, mafic flows containing 50 weight percent SiO2 and 2.3 weight percent K2O were extruded near the end of the rhyolite volcanic activity. The Blawn Formation records a shift in eruptive style and magmatic composition in the northern Wilson Creek Range. The Blawn was preceded by voluminous Oligocene eruptions of dominantly calc-alkaline orogenic magmas. The Blawn and younger volcanic rocks in the area are low-volume, bimodal suites of high-silica rhyolite tuffs and lava flows and mafic lava flows.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Brigham Young University Geology Studies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00681016","usgsCitation":"Willis, J., and Willis, G., 1996, Early miocene bimodal volcanism, Northern Wilson Creek Range, Lincoln County, Nevada: Brigham Young University Geology Studies, v. 41, p. 155-167.","startPage":"155","endPage":"167","numberOfPages":"13","costCenters":[],"links":[{"id":228721,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a048de4b0c8380cd50a52","contributors":{"authors":[{"text":"Willis, J.B.","contributorId":21620,"corporation":false,"usgs":true,"family":"Willis","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":377384,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Willis, G.C.","contributorId":18923,"corporation":false,"usgs":true,"family":"Willis","given":"G.C.","email":"","affiliations":[],"preferred":false,"id":377383,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These four minerals were isolated by density separation and handpicking from bituminous coal samples collected in the Ruhr Basin, Germany and the Appalachian basin, U.S.A. Trace-element concentrations of relatively pure (??? 99+%) separates of major minerals from these coals were determined directly by using instrumental neutron activation analysis (INAA). As expected, quartz contributes little to the trace-element mass balance. Illite generally has higher trace-element concentrations than kaolinite, but, for the concentrates analyzed in this study, Hf, Ta, W, Th and U are in lower concentrations in illite than in kaolinite. Pyrite has higher concentrations of chalcophile elements (e.g., As and Se) and is considerably lower in lithophile elements as compared to kaolinite and illite. Our study provides a direct and sensitive method of determining trace-element relationships with minerals in coal. Mass-balance calculations suggest that the trace-element content of coal can be explained mainly by three major minerals: pyrite, kaolinite and illite. This conclusion indicates that the size and textural relationships of these major coal minerals may be a more important consideration as to whether coal cleaning can effectively remove the most environmentally sensitive trace elements in coal than what trace minerals are present.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal of Coal Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0166-5162(96)00035-3","issn":"01665162","usgsCitation":"Palmer, C., and Lyons, P., 1996, Selected elements in major minerals from bituminous coal as determined by INAA: Implications for removing environmentally sensitive elements from coal: International Journal of Coal Geology, v. 32, no. 1-4, p. 151-166, https://doi.org/10.1016/S0166-5162(96)00035-3.","startPage":"151","endPage":"166","numberOfPages":"16","costCenters":[],"links":[{"id":228579,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206128,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0166-5162(96)00035-3"}],"volume":"32","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8c20e4b08c986b317ce9","contributors":{"authors":[{"text":"Palmer, C.A.","contributorId":81894,"corporation":false,"usgs":true,"family":"Palmer","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":377500,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lyons, P.C.","contributorId":87285,"corporation":false,"usgs":true,"family":"Lyons","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":377501,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

During 1986-88, the U.S. Geological Survey studied the distribution of ground-water levels in the alluvial plain between Moose Creek Dam and the confluence of the Tanana and Chena Rivers. Moose Creek Dam is a flood-control structure on the Chena River that impounds water only during high flows in the Chena River or during tests of the dam's control gates. Ground-water-level information is needed to help design and place septic systems, buildings, and drainage structures. Using 38 existing wells and 83 wells drilled for this study during 1986 and 1987, ground-water levels were measured to determine the depth to the water table, its seasonal variation, and its relation to changes in river and reservoir stages. Water levels were continuously measured in 10 wells and periodically measured in 110 other wells until August 1988. During 1989, water levels were measured at least once in 59 wells. Three wells were equipped with water-level recorders through 1993. River stages were measured continuously at one gaging station on the Tanana River and at two stations on the Chena River. During summer months of 1986-88, stages and discharges in the Chena River were generally less than long-term mean monthly values, whereas mean monthly stages and discharges in the Tanana River fluctuated above and below long-term mean monthly values. Depths to water in monitoring wells ranged from slightly above land surface to about 21 feet below land surface. Depths to water in the alluvial plain were within 10 feet of land surface in most areas, but were within 5 feet of land surface in many low-lying areas. In general, the water table sloped to the northwest, from the Tanana River to the Chena River, at a gradient of about 4 feet per mile. Water levels in wells within about half a mile of either river responded rapidly to changes in river stage. During summer months of 1989-93, stages and discharges in the Chena River were generally higher than those during 1986-88, whereas stages and discharges in the Tanana River were similar to those during 1986-88. During 1989, peak water levels were higher in more than half the wells measured than during peak levels observed during 1986-88. Peak water levels were also 1.9 to 3.3 feet higher in 1991 or 1992 than peak values during 1986-88 in three wells equipped with water-level recorders. Water levels in wells near Moose Creek Dam responded rapidly to changes in water levels behind the dam. During one impoundment, water levels in a well 0.1 mile from the dam rose approximately 7 feet, to 4.8 feet below land surface.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964060","usgsCitation":"Glass, R.L., Lilly, M.R., and Meyer, D.F., 1996, Ground-water levels in an alluvial plain between the Tanana and Chena Rivers near Fairbanks, Alaska 1986-93: U.S. Geological Survey Water-Resources Investigations Report 96-4060, iv, 39 p., https://doi.org/10.3133/wri964060.","productDescription":"iv, 39 p.","costCenters":[],"links":[{"id":414718,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48425.htm","linkFileType":{"id":5,"text":"html"}},{"id":56193,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4060/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123585,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4060/report-thumb.jpg"}],"country":"United States","state":"Alaska","city":"Fairbanks","otherGeospatial":"Chena River, Tanana River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -147.9364,\n              64.8925\n            ],\n            [\n              -147.9364,\n              64.7042\n            ],\n            [\n              -147.1228,\n              64.7042\n            ],\n            [\n              -147.1228,\n              64.8925\n            ],\n            [\n              -147.9364,\n              64.8925\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa8e4b07f02db66760a","contributors":{"authors":[{"text":"Glass, R.

Measuring concentrations of organochlorine compounds in bed sediment and fish tissue at the same site offers a more complete picture of the persistence of organochlorine compounds in the environment and their relation to land-use settings.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/BF00211330","usgsCitation":"Tate, C.M., and Heiny, J., 1996, Organochlorine compounds in bed sediment and fish tissue in the South Platte River Basin, USA, 1992-1993: Archives of Environmental Contamination and Toxicology, v. 30, no. 1, p. 62-78, https://doi.org/10.1007/BF00211330.","productDescription":"17 p.","startPage":"62","endPage":"78","numberOfPages":"17","costCenters":[],"links":[{"id":228670,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado, Nebraska, wyoming","otherGeospatial":"South Platte River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -103.50791177160265,\n              40.102209983118655\n            ],\n            [\n              -102.11708544817974,\n              40.86729533297759\n            ],\n            [\n              -100.88371116137036,\n              41.058851564577196\n            ],\n            [\n              -100.94494250894249,\n              41.263003441354925\n            ],\n            [\n              -104.58383402179747,\n              41.59093975886128\n            ],\n            [\n              -105.34485219876477,\n              41.51893590252098\n            ],\n            [\n              -105.63351426589048,\n              40.9598401710856\n            ],\n            [\n              -105.75597696103473,\n              40.382643192447944\n            ],\n            [\n              -105.5985249244207,\n              39.988371211327376\n            ],\n            [\n              -105.8259556439743,\n              39.38929334371295\n            ],\n            [\n              -105.87843965617898,\n              39.240406161168266\n            ],\n            [\n              -105.15241082068148,\n              39.0844127970922\n            ],\n            [\n              -104.4526239912863,\n              39.4433555592789\n            ],\n            [\n              -103.50791177160265,\n              40.102209983118655\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"30","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a700ee4b0c8380cd75e02","contributors":{"authors":[{"text":"Tate, C.

Water samples collected from 146 household supply wells were analyzed for fecal-indicator organisms including total coliform, fecal coliform, <i>Escherichia coli</i> (<i>E. coli</i>), and fecal streptococcus concentrations. Supporting data used in the interpretations are selected water-quality constituents, well-construction information, and the environmental setting at the well site including land use, physiography, and bedrock type. Water from nearly 70 percent of the wells sampled had total coliform present and thus was not suitable for drinking without treatment. Fecal coliforms were found in water from approximately 25 percent of the sampled wells. <i>E. coli</i> testing was not conducted in 1993. Approximately 30 percent of the 88 sampled wells had waters with <i>E. coli</i>. Fecal streptococcus bacteria was present in water from about 65 percent of the wells sampled. Bacteriological contamination was more likely to occur in water from wells in agricultural areas than in water from wells in forested areas. Water from wells sampled in the Ridge and Valley Physiographic Province was more likely to have bacteria than water from wells in the Piedmont Physiographic Province. Differences in bacterial concentrations among bedrock types are only statistically significant for <i>E. coli</i>. Bacterial concentrations are weakly related to well-age but not to other well characteristics such as the total well depth or the casing length. Relations exist between bacterial concentrations and selected water-quality constituents. Most wells from which water was sampled did not have sanitary seals and very few were grouted. This may have contributed to the number of detections of bacteria. It is uncertain whether the bacteria detected are the result of widespread aquifer contamination or site-specific factors.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964212","usgsCitation":"Bickford, T.M., Lindsey, B., and Beaver, M., 1996, Bacteriological quality of ground water used for household supply, Lower Susquehanna River basin, Pennsylvania and Maryland: U.S. Geological Survey Water-Resources Investigations Report 96-4212, viii, 31 p., https://doi.org/10.3133/wri964212.","productDescription":"viii, 31 p.","onlineOnly":"Y","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":55002,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4212/wri19964212.pdf","text":"Report","linkFileType":{"id":1,"text":"pdf"},"description":"WRI 1996-4212"},{"id":125110,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4212/coverthb.jpg"},{"id":415384,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48546.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maryland, Pennsylvania","otherGeospatial":"Lower Susquehanna River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -75.85,\n              41\n            ],\n            [\n              -78.5,\n              41\n            ],\n            [\n              -78.5,\n              39.5\n            ],\n            [\n              -75.85,\n              39.5\n            ],\n            [\n              -75.85,\n              41\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","contact":"<p><a href=\"mailto:dc_pa@usgs.gov\" data-mce-href=\"mailto:dc_pa@usgs.gov\">Director</a>, <a href=\"https://pa.water.usgs.gov/\" data-mce-href=\"https://pa.water.usgs.gov/\">Pennsylvania Water Science Center</a><br> U.S. Geological Survey<br> 215 Limekiln Road<br> New Cumberland, PA 17070</p>","tableOfContents":"<ul><li>Abstract</li><li>Introduction</li><li>Methods of study</li><li>Bacteriological quality of ground water used for household supply</li><li>Summary</li><li>References cited</li></ul>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ad68","contributors":{"authors":[{"text":"Bickford, Tammy M.","contributorId":16048,"corporation":false,"usgs":true,"family":"Bickford","given":"Tammy","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":195982,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lindsey, Bruce D. 0000-0002-7180-4319 blindsey@usgs.gov","orcid":"https://orcid.org/0000-0002-7180-4319","contributorId":434,"corporation":false,"usgs":true,"family":"Lindsey","given":"Bruce D.","email":"blindsey@usgs.gov","affiliations":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"preferred":false,"id":195981,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Beaver, M.R.","contributorId":21998,"corporation":false,"usgs":true,"family":"Beaver","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":195983,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These efforts attempt to estimate the continuous growth of green biomass by using continuous additions of NDVI as a surrogate measure. To build upon this concept, this study proposes three refinements; 1) use an objective definition of the current growing season to adjust the time window during which the NDVI is accumulated, 2) accumulate only the NDVI values which are affected by green vegetation, and 3) base monitoring units upon land cover type. These refinements improve the sensitivity of detecting interannual vegetation variability, reduce the need for extensive and detailed knowledge of ground conditions and crop calendars, provide a framework in which several types of monitoring can take place over diverse land cover types, and provide an objective time frame during which monitoring takes place.","language":"English","publisher":"Taylor & Francis","doi":"10.1080/10106049609354544","issn":"10106049","usgsCitation":"Reed, B., Loveland, T., and Tieszen, L., 1996, An approach for using AVHRR data to monitor U.S. great plains grasslands: Geocarto International, v. 11, no. 3, p. 13-22, https://doi.org/10.1080/10106049609354544.","startPage":"13","endPage":"22","numberOfPages":"10","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":228630,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ea0be4b0c8380cd485d1","contributors":{"authors":[{"text":"Reed, B.

We report the results of our cloud detection and characterization study using Mars near IR images obtained during the 1990 and 1993 oppositions. We focused on specific wavelengths that have the potential, based on previous laboratory studies of H</span><sub>2</sub><span>O and CO</span><sub>2</sub><span>&nbsp;ices, of yielding the greatest degree of cloud detectability and compositional discriminability. We have detected and mapped absorption features at some of these wavelengths in both the northern and southern polar regions of Mars. Compositional information on the nature of these absorption features was derived from comparisons with laboratory ice spectra and with a simplified radiative transfer model of a CO</span><sub>2</sub><span>&nbsp;ice cloud overlying a bright surface. Our results indicate that both H</span><sub>2</sub><span>O and CO</span><sub>2</sub><span>&nbsp;ices can be detected and distinguished in the polar hood clouds.

The match is improved significantly when the processes of evapotranspiration and infiltration are considered. The best results are obtained when snowmelt is also included in the model. Potential evapotranspiration was estimated with Thornthwaite's formula, infiltration was calculated through a water-balance approach, and snowmelt was generated by a degree-day model. The results show that groundwater in the limestone aquifer is mainly recharged by snowmelt in early spring and by infiltration from rainfall in later spring and early summer. Simulated discharge was visually calibrated against measured discharge; the similarity between the two supports the validity of this approach.

For many species, total investment in a clutch is limited by the size of stored reserves (Ankney and MacInnes 1978, Esler and Grand 1994a). Egg size determines the unit by which these stored reserves are partitioned. Individual females in most species of waterfowl show a high repeatability for egg size, implying that individual either cannot, or do not, alter their egg size in response to varying environmental conditions (batt and Prince 1979, Duncan 1987, Laurila and Hario 1988, Lessells et al 1989, Flint and Sedinger 1992). Thus differences in egg size appear to represent different reproductive strategies among individuals.</p><p>Fitness can be measured by the number of offspring an individual contributes to a population. Egg size may be related to fitness in some species fo waterfowl as young from larger eggs are better able to survive extreme conditions (Ankney 1980, Thomas and Brown 1988). Birds laying larger clutches are almost always more fit as they fledge more young (Lessells 1986, Rockwell et al 1987, Flint 1993). These fitness patterns create the potential for a trade-off between clutch size and egg size where females laying large clutches of small eggs have the same fitness as females laying smaller clutches of large eggs. The fact that Northern Pintails (<i>Anas acuta</i>) utilize stored reserves (Mann and Sedinger 1993, esler and Grand 1994a) and have a high repeatability for egg size (i.e. egg size is fixed) (Duncan 1987), makes them candidates to engage in clutch size=egg size trade-offs (Rowher 1988, Rowher and Eisenhauer 1989). An inverse relationship between egg size and clutch size would be indicative of a phenotypic trade-off among these fitness components. Our goal in this study was to describe egg size variation in Northern Pintails (hereafter pintails) with regard to female age, body size, clutch size, year, initiation date, and nesting attempt. We compare our results to those from other populations of nesting pintails and discuss whether phenotypic clutch size-egg size tradeoffs exist for pintails.</p>","language":"English","publisher":"Cooper Ornithological Society","doi":"10.2307/1369519","usgsCitation":"Flint, P.L., and Grand, J.B., 1996, Variation in egg size of the northern pintail: The Condor, v. 98, no. 1, p. 162-165, https://doi.org/10.2307/1369519.","productDescription":"4 p.","startPage":"162","endPage":"165","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":479079,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2307/1369519","text":"Publisher Index Page"},{"id":335636,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Kashunuk River drainage, Yukon Delta National Wildlife Refuge","volume":"98","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a57707e4b057081a24ee8c","contributors":{"authors":[{"text":"Flint, Paul L. 0000-0002-8758-6993 pflint@usgs.gov","orcid":"https://orcid.org/0000-0002-8758-6993","contributorId":3284,"corporation":false,"usgs":true,"family":"Flint","given":"Paul","email":"pflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":669435,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grand, J.

Non-native species averaged 95 per park, or about 27% on average of the total number of taxa per park. The aggregated regional flora contained just over 2,900 taxa, 828 genera and 160 families. Eleven percent of the taxa were below the species level. Almost 17% of the taxa were non-native, a relatively large percentage, but not out of the range of percentages reported in the literature. The observed and estimated numbers of taxa for this region were in good agreement with other estimates for these latitudes and for a standard regional size. However, the parks do not represent their respective state floras very well when they are aggregated at that scale. Indiana was the best represented state with 65% of the state flora found in the parks, while only 25% of each state's flora were represented by parks in Iowa, Kansas, and Nebraska, and the average
