However, compositions and isotope abundances of noble gases and delta <sup>13</sup>C values of HCO<sub>3</sub> indicate a significant (up to 50%) mantle component for the volatiles.

In the Eagle collapse center, Pennsylvanian evaporite flowed to form anticlinal diapirs, dissolved, and disrupted a lower Miocene basaltic plateau originally at elevations as high as 3.35 km by tilting, faulting, and sagging to elevations as low as about 2.1 km. Also in the Eagle collapse center, the 30 x 10-km, homoclinal Hardscrabble Mountain sank into evaporite during Triassic and Permian collapse followed by Neogene(?) tilting and collapse, based on seismic reflection data. Along the southwestern flank of the White River uplift in the northwestern part of the Carbondale collapse center, parts of the Grand Hogback monocline have collapsed northeastward toward a series of strike-elongate extrusive diapirs. The volume of evaporite removed from the Eagle and Carbondale collapse centers during the Neogene (about 2,250 km<sup>3</sup> from an area of roughly 4,500 km<sup>2</sup>) was calculated by measuring the departure of collapsed basalts from an assumed original basalt plateau. Regional Neogene uplift and incision of the Rocky Mountains, which locally began about 8-10 Ma, probably triggered dissolution and collapse. Presently the Colorado River removes a dissolved-solids load of about 1.4 x 10<sup>9</sup> kg per year from the two collapse centers.</p>","largerWorkTitle":"Colorado and adjacent areas","language":"English","publisher":"Geological Society of America","publisherLocation":"Boulder, CO","doi":"10.1130/0-8137-0001-9.97","usgsCitation":"Scott, R.B., Lidke, D., Hudson, M., Perry, W.J., Bryant, B., Kunk, M.J., Budahn, J., and Byers, F., 1999, Active evaporite tectonics and collapse in the Eagle River valley and the southwestern flank of the White River uplift, Colorado: GSA Field Guides, v. 1, p. 97-114, https://doi.org/10.1130/0-8137-0001-9.97.","productDescription":"18 p.","startPage":"97","endPage":"114","numberOfPages":"18","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"links":[{"id":282936,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"Eagle River, White River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -108.65,38.41 ], [ -108.65,40.7 ], [ -105.12,40.7 ], [ -105.12,38.41 ], [ -108.65,38.41 ] ] ] } } ] }","volume":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4b15e4b0b290850f0247","contributors":{"authors":[{"text":"Scott, R.

Because heat transfer from thermal windows located in peripheral sites of these mammals depends on blood flow, such adjustments may limit their thermoregulatory capabilities during submergence. Here, we demonstrate how the thermoregulatory responses of bottlenose dolphins (</span><i>Tursiops truncatus</i><span>) are coordinated with the diving response. Heart rate, skin temperature and heat transfer from the dorsal fin and flank were measured while dolphins rested on the water surface, stationed 5–50 m under water and floated at the surface immediately following a dive. The results showed that heat flow ranged from 42.9±7.3 to 126.2±23.1 W m</span><sup>−2</sup><span>&nbsp;and varied with anatomical site and diving activity. Upon submergence, heat flow declined by 35 % from the dorsal fin and by 24 % from the flank. An immediate increase in heat flow to levels exceeding pre-dive values occurred at both sites upon resurfacing. Changes in heart rate during diving paralleled the thermoregulatory responses. Mean pre-dive heart rate (102.0±2.6 beats min</span><sup>−1</sup><span>,&nbsp;</span><i>N</i><span>=26) decreased by 63.4 % during dives to 50 m and immediately returned to near resting levels upon resurfacing. These studies indicate that heat dissipation by dolphins is attenuated during diving. Rather than challenge the diving response, heat transfer is delayed until post-dive periods when the need for oxygen conservation is reduced.</span></p>","language":"English","publisher":"Company of Biologists","doi":"10.1242/jeb.202.20.2763","usgsCitation":"Williams, T.M., Noren, D., Berry, P., Estes, J.A., Allison, C., and Kirtland, J., 1999, The diving physiology of bottlenose dolphins (Tursiops truncatus).

Acoustic facies integrated with geometry define six architectural elements, some with discrete subelements that are of a scale that can be recognized in outcrops of ancient turbidite systems. In the Santa Monica Basin, the relationship of these elements to fan morphology, stratigraphy and sediment source is precisely known. The width of upper Hueneme fan valley has been reduced from 5 km since the last glacial maximum to 1 km at present by construction of laterally confined sandy levees within the main valley. The middle fan comprises three main subelements: thick sand deposits at the termination of the fan valley, low-gradient sandy lobes typically 5 km long and < 10 m thick, and scoured lobes formed of alternating sand and mud beds with many erosional depressions. The site of thickest lobe sediment accumulation shifts through time, with each sand bed deposited in a previous bathymetric low (i.e. compensation cycles). The lower fan and basin plain consists of sheet-like alternations of sand and mud with shallow channels and lenses. Variations in the rate of late Quaternary sea level rise initiated changes in sediment facies distribution. At lowstand, and during the approximately 11 ka stillstand in sea level, the Hueneme Fan was fed largely by hyperpycnal flow from the Santa Clara River delta, depositing high sediment waves on the right hand levee and thick sandy lobes on the middle fan. At highstand of sea level, most turbidity currents were generated by failure of silty prodelta muds. In contrast, the smaller Dume Fan was apparently always fed from littoral drift of sand through a single-canyon point source.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Sedimentology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1046/j.1365-3091.1999.00203.x","issn":"00370746","usgsCitation":"Piper, D., Hiscott, R., and Normark, W.R., 1999, Outcrop-scale acoustic facies analysis and latest Quaternary development of Hueneme and Dume submarine fans, offshore California: Sedimentology, v. 46, no. 1, p. 47-78, https://doi.org/10.1046/j.1365-3091.1999.00203.x.","startPage":"47","endPage":"78","numberOfPages":"32","costCenters":[],"links":[{"id":206274,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1365-3091.1999.00203.x"},{"id":229274,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"1","noUsgsAuthors":false,"publicationDate":"2002-04-21","publicationStatus":"PW","scienceBaseUri":"505a71a9e4b0c8380cd766d0","contributors":{"authors":[{"text":"Piper, D.J.W.","contributorId":17351,"corporation":false,"usgs":false,"family":"Piper","given":"D.J.W.","email":"","affiliations":[{"id":7219,"text":"Natural Resources Canada","active":true,"usgs":false}],"preferred":false,"id":391613,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hiscott, R.N.","contributorId":96438,"corporation":false,"usgs":true,"family":"Hiscott","given":"R.N.","email":"","affiliations":[],"preferred":false,"id":391615,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Normark, W.

The ingesta had mean Al concentrations (2,384 μg/g, dry weight) and Al:P molar ratios (6.4:1) predicted to affect bone integrity but the bone concentrations of Al were near the normal range and the furcula stiffness did not change with Al concentration. The tan δ of the furculae changed with Al concentration but the relationship was weak. The chemical speciation of the ingested Al may have affected its physiologic role and the high mean levels of ingested calcium (71,283 μg/g, dry weight) very likely neutralized the activity of the Al. Controlled feeding studies have shown that F strengthens avian bones.

Evaluation of hematologic and biochemical responses of desert tortoises to physiologic and environmental factors can facilitate the assessment of stress and disease in tortoises and contribute to management decisions and population recovery. The goal of this study was to obtain and analyze clinical laboratory data from free-ranging desert tortoises at three sites in the Mojave Desert (California, USA) between October 1990 and October 1995, to establish reference intervals, and to develop guidelines for the interpretation of laboratory data under a variety of environmental and physiologic conditions. Body weight, carapace length, and venous blood samples for a complete blood count and clinical chemistry profile were obtained from 98 clinically healthy adult desert tortoises of both sexes at the Desert Tortoise Research Natural area (western Mojave), Goffs (eastern Mojave) and Ivanpah Valley (northeastern Mojave). Samples were obtained four times per year, in winter (February/March), spring (May/June), summer (July/August), and fall (October). Years of near-, above- and below-average rainfall were represented in the 5 yr period. Minimum, maximum and median values, and central 95 percentiles were used as reference intervals and measures of central tendency for tortoises at each site and/or season. Data were analyzed using repeated measures analysis of variance for significant (</span><i>P</i><span> &lt; 0.01) variation on the basis of sex, site, season, and interactions between these variables. Significant sex differences were observed for packed cell volume, hemoglobin concentration, aspartate transaminase activity, and cholesterol, triglyceride, calcium, and phosphorus concentrations. Marked seasonal variation was observed in most parameters in conjunction with reproductive cycle, hibernation, or seasonal rainfall. Year-to-year differences and long-term alterations primarily reflected winter rainfall amounts. Site differences were minimal, and largely reflected geographic differences in precipitation patterns, such that results from these studies can be applied to other tortoise populations in environments with known rainfall and forage availability patterns.</span></p>","language":"English","publisher":"Wildlife Disease Association","doi":"10.7589/0090-3558-35.2.212","usgsCitation":"Christopher, M.M., Berry, K.H., Wallis, I., Nagy, K., Henen, B., and Peterson, C., 1999, Reference intervals and physiologic alterations in hematologic and biochemical values of free-ranging desert tortoises in the Mojave Desert: Journal of Wildlife Diseases, v. 35, no. 2, p. 212-238, https://doi.org/10.7589/0090-3558-35.2.212.","productDescription":"27 p.","startPage":"212","endPage":"238","numberOfPages":"27","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":479615,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.7589/0090-3558-35.2.212","text":"Publisher Index Page"},{"id":133065,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db6351ff","contributors":{"authors":[{"text":"Christopher, Mary M.","contributorId":44473,"corporation":false,"usgs":true,"family":"Christopher","given":"Mary","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":316752,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berry, Kristin H. 0000-0003-1591-8394 kristin_berry@usgs.gov","orcid":"https://orcid.org/0000-0003-1591-8394","contributorId":437,"corporation":false,"usgs":true,"family":"Berry","given":"Kristin","email":"kristin_berry@usgs.gov","middleInitial":"H.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":316750,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wallis, I.R.","contributorId":80612,"corporation":false,"usgs":true,"family":"Wallis","given":"I.R.","email":"","affiliations":[],"preferred":false,"id":316755,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nagy, K.A.","contributorId":39727,"corporation":false,"usgs":true,"family":"Nagy","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":316753,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Henen, B.T.","contributorId":67457,"corporation":false,"usgs":true,"family":"Henen","given":"B.T.","affiliations":[],"preferred":false,"id":316754,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peterson, C.C.","contributorId":24725,"corporation":false,"usgs":true,"family":"Peterson","given":"C.C.","email":"","affiliations":[],"preferred":false,"id":316751,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Efforts to find a reasonable and practical definition of “natural” have helped drive scientists and land managers to use past grove conditions as reference conditions for restoration. Extensive research aimed at determining reference conditions has demonstrated that past fire regimes can be characterized with greater precision than past grove structures. Difficulty and imprecision in determining past grove structure has helped fuel a debate between “structural restorationists,” who believe that forest structure should be restored mechanically before fire is reintroduced, and “process restorationists,” who believe that simple reintroduction of fire is appropriate. I evaluate old and new studies from sequoia groves to show that some of the arguments of both groups have been flawed. Importantly, it appears that restoration of fire without a preceding mechanical restoration may restore the pre-Euro-American structure of sequoia groves, at least within the bounds of our imprecise knowledge of past grove structure.

This has led to the hypothesis that Everglades hammock trees are more reliant on soil moisture derived from local precipitation whereas pineland plants must depend more on groundwater linked to broader regional hydrologic patterns. Because soil moisture sources are likely to vary more than groundwater sources, we hypothesized that hammock plants would exhibit correspondingly higher levels of dry season water stress. This was examined by measuring predawn water potentials, and by analyzing water uptake in representative hammock and pineland woody species using stable isotopes of plant water and that of potential sources during wet and dry seasons. Two species typical of each of the two communities were selected; a fifth species which was found in both communities, Lysiloma latisiliqua Benth., was also analyzed. Water content of soils in both communities decreased from wet to dry season. Consistent with our hypothesis, the change in predawn water potentials between the wet and dry season was less in pineland species than that of hammock species. Water potential changes in L. latisiliqua in both communities resembled that of hammock species more than pineland plants. Isotopic data showed that pineland species rely proportionately more on groundwater than hammock species. Nevertheless, unlike hammock species in the Florida Keys, mainland hammock species utilized a substantial amount of groundwater during the dry season.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Forest Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0378-1127(98)00493-9","issn":"03781127","usgsCitation":"Ewe, S., da Silveira Lobo Sternberg, L., Sternberg, L., and Busch, D., 1999, Water-use patterns of woody species in pineland and hammock communities of South Florida: Forest Ecology and Management, v. 118, no. 1-3, p. 139-148, https://doi.org/10.1016/S0378-1127(98)00493-9.","startPage":"139","endPage":"148","numberOfPages":"10","costCenters":[],"links":[{"id":487289,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/s0378-1127(98)00493-9","text":"Publisher Index Page"},{"id":229203,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206244,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0378-1127(98)00493-9"}],"volume":"118","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bcf2fe4b08c986b32e789","contributors":{"authors":[{"text":"Ewe, S.M.L.","contributorId":78496,"corporation":false,"usgs":true,"family":"Ewe","given":"S.M.L.","email":"","affiliations":[],"preferred":false,"id":389965,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"da Silveira Lobo Sternberg, Leonel","contributorId":47932,"corporation":false,"usgs":true,"family":"da Silveira Lobo Sternberg","given":"Leonel","affiliations":[],"preferred":false,"id":389963,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sternberg, L.","contributorId":58984,"corporation":false,"usgs":true,"family":"Sternberg","given":"L.","email":"","affiliations":[],"preferred":false,"id":389964,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Busch, D.E.","contributorId":6213,"corporation":false,"usgs":true,"family":"Busch","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":389962,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The final extraction and cleanup methods chosen for use are suitable for the quantification of the listed pesticides using gas chromatography-ion trap mass spectrometry and the removal of interfering coextractable organic material found in suspended sediments. Methylene chloride extraction followed by Florisil cleanup proved most effective for separation of coextractives from the pesticide analytes. Removal of elemental sulfur was accomplished with tetrabutylammonium hydrogen sulfite. The suitability of the method for the analysis of a variety of pesticides was evaluated, and the method detection limits (MDLs) were determined (0.1-6.0 ng/g dry weight of sediment) for 21 compounds. Recovery of pesticides dried onto natural sediments averaged 63%. Analysis of duplicate San Joaquin River suspended-sediment samples demonstrated the utility of the method for environmental samples with variability between replicate analyses lower than between environmental samples. Eight of 21 pesticides measured were observed at concentrations ranging from the MDL to more than 80 ng/g dry weight of sediment and exhibited significant temporal variability. Sediment-associated pesticides, therefore, may contribute to the transport of pesticides through aquatic systems and should be studied separately from dissolved pesticides.</p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/02772249909358713","issn":"02772248","usgsCitation":"Bergamaschi, B., Baston, D., Crepeau, K., and Kuivila, K., 1999, Determination of pesticides associated with suspended sediments in the San Joaquin River, California, USA, using gas chromatography-ion trap mass spectrometry: Toxicological and Environmental Chemistry, v. 69, no. 3-4, p. 305-319, https://doi.org/10.1080/02772249909358713.","productDescription":"15 p.","startPage":"305","endPage":"319","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":229168,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ffbce4b0c8380cd4f37e","contributors":{"authors":[{"text":"Bergamaschi, B.A. 0000-0002-9610-5581","orcid":"https://orcid.org/0000-0002-9610-5581","contributorId":22401,"corporation":false,"usgs":true,"family":"Bergamaschi","given":"B.A.","affiliations":[],"preferred":false,"id":389956,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baston, D.S.","contributorId":49131,"corporation":false,"usgs":true,"family":"Baston","given":"D.S.","email":"","affiliations":[],"preferred":false,"id":389958,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Crepeau, K.L.","contributorId":9018,"corporation":false,"usgs":true,"family":"Crepeau","given":"K.L.","affiliations":[],"preferred":false,"id":389955,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kuivila, K.M.","contributorId":34529,"corporation":false,"usgs":true,"family":"Kuivila","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":389957,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Fish acclimated to brackish water (BW, 10&nbsp;ppt salinity) were injected with a single dose of hormone suspended in oil and transferred to seawater (SW, 35&nbsp;ppt salinity) 10 days post-injection. Fish were sampled 24&nbsp;h after transfer and plasma osmolality and gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity were examined. Transfer from BW to SW induced significantly increased plasma osmolality but not gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity. Cortisol (50&nbsp;μg&nbsp;g<sup>−1</sup>&nbsp;body weight) improved the ability to maintain plasma osmolality and to increase gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity. oGH (5&nbsp;μg&nbsp;g<sup>−1</sup>&nbsp;body weight) also increased hypoosmoregulatory ability and gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity. A cooperation between oGH and cortisol was observed in increasing hypoosmoregulatory ability but not in increasing gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity. rbIGF-I (0.5&nbsp;μg&nbsp;g<sup>−1</sup>&nbsp;body weight) alone was without effect in increasing salinity tolerance or gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity. rbIGF-I and oGH showed a positive interaction in increasing salinity tolerance, but not gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity. Treatment with T<sub>3</sub>&nbsp;(5&nbsp;μg&nbsp;g<sup>−1</sup>&nbsp;body weight) alone did not increase salinity tolerance or gill Na<sup>+</sup>, K<sup>+</sup>-ATPase activity, and there was no consistent significant interaction between cortisol and T<sub>3</sub>&nbsp;or between GH and T<sub>3</sub>. The results confirm the classical role of cortisol as a seawater-adapting hormone and indicate an interaction between cortisol and the GH/IGF-I axis during seawater acclimation of Fundulus heteroclitus.<br data-mce-bogus=\"1\"></p>","language":"English","publisher":"Springer Link","doi":"10.1023/A:1007737924339","usgsCitation":"Mancera, J.M., and McCormick, S., 1999, Influence of cortisol, growth hormone, insulin-like growth factor I and 3,3′,5-triiodo-l-thyronine on hypoosmoregulatory ability in the euryhaline teleost Fundulus heteroclitus: Fish Physiology and Biochemistry, v. 21, no. 1, p. 25-33, https://doi.org/10.1023/A:1007737924339.","productDescription":"9 p.","startPage":"25","endPage":"33","numberOfPages":"9","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":131406,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f1e4b07f02db5ee50b","contributors":{"authors":[{"text":"Mancera, J.
