Analysis of blood films from 350 turkeys revealed&nbsp;</span><i>Haemoproteus meleagridis</i><span>&nbsp;in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of&nbsp;</span><i>H. meleagridis</i><span>&nbsp;than birds from Chaparrosa. The&nbsp;</span><i>Plasmodium</i><span>&nbsp;sp. was infective for canaries (</span><i>Serinus canaria</i><span>), bobwhites (</span><i>Colinus virginianus</i><span>), and ring-necked pheasants (</span><i>Phasianus colchicus</i><span>), but would not produce infection in white leghorn chickens (</span><i>Gallus gallus</i><span>) or Coturnix quail (</span><i>Coturnix coturnix</i><span>). Attempts to infect&nbsp;</span><i>Culex tarsalis</i><span>&nbsp;and&nbsp;</span><i>C. pipiens pipiens</i><span>&nbsp;were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The&nbsp;</span><i>Plasmodium</i><span>&nbsp;sp. is most similar morphologically to three species in the subgenus&nbsp;</span><i>Novyella</i><span>,&nbsp;</span><i>P. hexamerium</i><span>,&nbsp;</span><i>P. vaughani</i><span>, and&nbsp;</span><i>P. kempi</i><span>. The most striking similarities are to&nbsp;</span><i>P. hexamerium</i><span>, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from&nbsp;</span><i>P. vaughani</i><span>&nbsp;in being able to infect turkeys and in type of parasitized erythrocytes. Differences to&nbsp;</span><i>P. kempi</i><span>&nbsp;include mean merozoite number, and ability to infect pheasants, and its inability to develop in</span><i>C. pipiens</i><span>&nbsp;and&nbsp;</span><i>C. tarsalis</i><span>.</span></p>","language":"English","publisher":"Wildlife Disease Association","doi":"10.7589/0090-3558-24.1.88","usgsCitation":"Castle, M.D., Christensen, B.A., and Rocke, T.E., 1988, Hematozoan parasites of Rio Grande wild turkeys from southern Texas (USA): Journal of Wildlife Diseases, v. 24, no. 1, p. 88-96, https://doi.org/10.7589/0090-3558-24.1.88.","productDescription":"9 p.","startPage":"88","endPage":"96","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":480025,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.7589/0090-3558-24.1.88","text":"Publisher Index Page"},{"id":134029,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Texas","county":"San Patricio County, Willacy County, Zavala County","otherGeospatial":"Campo Allegre Ranch, Chaparrosa Ranch, Welder Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -98.03375244140625,\n              26.30080200905286\n            ],\n            [\n              -97.49267578125,\n              26.30080200905286\n            ],\n            [\n              -97.49267578125,\n              26.61063004014913\n            ],\n            [\n              -98.03375244140625,\n              26.61063004014913\n            ],\n            [\n              -98.03375244140625,\n              26.30080200905286\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -100.1568603515625,\n              28.815799886487298\n            ],\n            [\n              -99.93438720703125,\n              28.815799886487298\n            ],\n            [\n              -99.93438720703125,\n              29.104176683949984\n            ],\n            [\n              -100.1568603515625,\n              29.104176683949984\n            ],\n            [\n              -100.1568603515625,\n              28.815799886487298\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"24","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db689908","contributors":{"authors":[{"text":"Castle, Marc D.","contributorId":96232,"corporation":false,"usgs":true,"family":"Castle","given":"Marc","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":314546,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Christensen, Beth A.","contributorId":36523,"corporation":false,"usgs":false,"family":"Christensen","given":"Beth","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":314544,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"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":314545,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Information from drill hole lithologies, surface geology, and structural geology interpretations constrain the model. Some important points revealed by the three-dimensional gravity modeling are that (1) the volume of ejected magma associated with the Bishop Tuff eruption is greater than previously thought, (2) the caldera structure is strongly influenced by precaldera topography and the extensions of major, active faults, (3) the main west ring fracture is coincident with the Inyo Domes-Mono Craters fracture system, (4) a relatively low-density region probably underlies the caldera, and (5) a silicic magma chamber may underlie Devils Postpile.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB093iB11p13237","issn":"01480227","usgsCitation":"Carle, S.F., 1988, Three-dimensional gravity modeling of the geologic structure of Long Valley caldera: Journal of Geophysical Research Solid Earth, v. 93, no.

Comparison of results with data from other studies in this area and from other areas, and with various water-quality standards or criteria, indicate that selenium probably is the principal contaminant of concern in the Salton Sea basin and that it probably is related to agricultural practices. Selenium is mobilized in the subsurface drainwater produced by agricultural irrigation and transported in ditches and rivers, some of which pass through or near the Salton Sea National Wildlife Refuge before entering the Salton Sea. Some selenium apparently is incorporated into the food chain. In response to the finding of elevated selenium residues in fish from the area by State agencies, the Imperial County Health Department has issued a health advisory restricting or prohibiting human consumption of fish from the Salton Sea and drains.","conferenceTitle":"Planning Now for Irrigation and Drainage in the 21st Century","conferenceDate":"18 July 1988 through 21 July 1988","conferenceLocation":"Lincoln, NE, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","isbn":"0872626660","usgsCitation":"Schroeder, R.A., Setmire, J.G., and Wolfe, J.C., 1988, Trace elements and pesticides in Salton Sea area, California, Planning Now for Irrigation and Drainage in the 21st Century, Lincoln, NE, USA, 18 July 1988 through 21 July 1988, p. 700-707.","startPage":"700","endPage":"707","numberOfPages":"8","costCenters":[],"links":[{"id":225439,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb646e4b08c986b326b84","contributors":{"authors":[{"text":"Schroeder, Roy A. raschroe@usgs.gov","contributorId":1523,"corporation":false,"usgs":true,"family":"Schroeder","given":"Roy","email":"raschroe@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":368113,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Setmire, James G.","contributorId":105284,"corporation":false,"usgs":true,"family":"Setmire","given":"James","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":368115,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wolfe, John C.","contributorId":96021,"corporation":false,"usgs":true,"family":"Wolfe","given":"John","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":368114,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Some of these lavas are spatially associated with thermal springs, and this association has prompted some workers to hypothesize that the hot water derives its thermal energy from the shallow, still hot intrusive roots of the volcanic rocks. However, all of the volcanic rocks appear to represent mantle-derived mafic magma that rose rather quickly to the Earth's surface, without filling crustal reservoirs within which differentiation would have produced evolved, derivative products. Moreover, the lavas are too old and of too small a volume to represent the surface expression of an active reservoir of magma within the crust. These interpretations of the volcanic geology are consistent with conclusions drawn from the chemistry of the thermal water; the water has equilibrated with host rocks at no more than 110°C, probably at depths of 2–3 km. Thus, thermal springs along the Jordan rift appear to reflect heating during circulation through a regional regime of average crustal heat flow (Galanis&nbsp;</span><i>et at.</i><span>, 1986).

Some investigators have interpreted these observations as evidence that seismic quiescence is a somewhat reliable precursor to moderate or large earthquakes. However, because failures of the pattern to predict earthquakes may not, in general, be reported, and because numerous earthquakes are not preceded by quiescence, the validity and reliability of the quiescence precursor have not been established. We have analyzed the seismicity rate prior to, and in the source region of, 37 shallow earthquakes (M 5.3-7.0) in central California and Japan for patterns of rate fluctuation, especially precursory quiescence. Nonuniformity in rate for these pre-mainshock sequences is relatively high, and numerous intervals with significant (p<0.10) extrema in rate are observed in some of the sequences. In other sequences, however, the rate remains within normal limits up to the time of the mainshock. Overall, in terms of an observational basis for intermediate-term earthquake prediction, no evidence is found in the cases studied for a systematic, widespread or reliable pattern of quiescence prior to the mainshocks. In earthquake sequences comprising full seismic cycles for 5 sets of (M 3.7-5.1) repeat earthquakes on the San Andreas fault near Bear Valley, California, the seismicity rates are found to be uniform. A composite of the estimated rate fluctuations for the sequences, normalized to the length of the seismic cycle, reveals a weak pattern of a low rate in the first third of the cycle, and a high rate in the last few months. While these observations are qualitative, they may represent weak expressions of physical processes occurring in the source region over the seismic cycle. Re-examination of seismicity rate fluctuations in volumes along the creeping section of the San Andreas fault specified by Wyss and Burford (1985) qualitatively confirms the existence of low-rate intervals in volumes 361, 386, 382, 372 and 401. However, only the quiescence in volume 386 is found by the present study to be statistically significant. ?? 1988 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00879004","issn":"00334553","usgsCitation":"Reasenberg, P., and Matthews, M., 1988, Precursory seismic quiescence: A preliminary assessment of the hypothesis: Pure and Applied Geophysics PAGEOPH, v. 126, no. 2-4, p. 373-406, https://doi.org/10.1007/BF00879004.","startPage":"373","endPage":"406","numberOfPages":"34","costCenters":[],"links":[{"id":205648,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00879004"},{"id":225699,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"126","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a814ce4b0c8380cd7b463","contributors":{"authors":[{"text":"Reasenberg, P.A.","contributorId":19959,"corporation":false,"usgs":true,"family":"Reasenberg","given":"P.A.","email":"","affiliations":[],"preferred":false,"id":368148,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Matthews, M.V.","contributorId":70920,"corporation":false,"usgs":true,"family":"Matthews","given":"M.V.","email":"","affiliations":[],"preferred":false,"id":368149,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Along strike-slip faults, the coseismic and interseismic deformation can be nearly equal in magnitude and opposite in sign, resulting in little permanent deformation except for the fault offset. For dip-slip faults, portions of the crust are lifted and dropped, and so buoyancy forces are exerted. The seismic and interseismic deformations do not balance, and structures grow and become subject to erosion and deposition. We consider three examples for which the structure and fault geometry are well known: the White Wolf reverse fault in California, site of the 1952 Kern County M=7.3 earthquake, the Lost River normal fault in Idaho, site of the 1983 Borah Peak M=7.0 earthquake, and the Cricket Mountain normal fault in Utah, site of Quaternary slip events. Basin stratigraphy and seismic reflection records are used to profile the structure, and coseismic deformation measured by leveling surveys is used to estimate the fault geometry. To reproduce these structures, we add the deformation associated with the earthquake cycle (the coseismic slip and postseismic relaxation) to the flexure caused by the observed sediment load, treating the crust as a thin elastic plate overlying a fluid substrate. The cumulative deformation is principally dependent on the elastic plate thickness, modestly sensitive to the sediment-substrate density difference, and insensitive to the fluid viscosity for the 4- to 8-Ma structures. We deduce a longterm flexural rigidity of 2–15 × 10</span><sup>19</sup><span>&nbsp;Nm; this is equivalent to an elastic plate thickness of 2–4 km for a Young's modulus of 2.5 × 10</span><sup>10</sup><span>&nbsp;Nm</span><sup>−2</sup><span>. This value is found where independent estimates of the elastic thickness from the coherence between surface topography and gravity yield values of about 4 km, but where coseismic fault slip extends to a depth of 10–15 km. Thus much of the seismogenic crust must weaken substantially during the life of active faults, causing the fault-bounded basins to narrow over time.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB093iB11p13319","issn":"01480227","usgsCitation":"Stein, R., King, G., and Rundle, J.B., 1988, The growth of geological structures by repeated earthquakes: 2, Field examples of continental dip-slip faults: Journal of Geophysical Research Solid Earth, v. 93, no.

Such systems can evolve within low-permeability barriers without changes in boundary conditions or rock properties, given an adequate supply of heat. Their scarcity in nature may be due to the need for a long-lived, potent heat source and for a low-permeability aureole that remains intact for significant lengths of time. Models II and III represent systems with significant liquid throughflow and include steam-heated discharge features at higher elevations and high-chloride springs at lower elevations, connected to and fed by a single circulation system at depth. In model II, as in model I, the vapor-dominated zone has a near-vaporstatic vertical pressure gradient and is generally underpressured with respect to local hydrostatic pressure. The vapor-dominated zone in model III is quite different, in that phase separation takes place at pressures close to local hydrostatic and the overall pressure gradient is near hydrostatic.

A storm in May 1986 caused a rapid increase in discharge that was accompanied by a decrease in streamwater temperature and a rise in the water table level adjacent to the stream. The higher water table provided the hydraulic gradient necessary to increase the discharge of colder groundwater to the stream. Storms that occurred under very dry antecedent conditions in July 1986 and June 1987 caused a rapid hydrologic response but no change in water table level, indicating the response was caused by channel interception of rainwater. This conclusion was supported by increases in streamwater temperature in the June storm and by chemical changes in the July storm. When rainfall is sufficient, flow in the ephemeral part of the stream in the catchment headwaters generates a second and larger discharge peak that reflects the chemistry and temperature of runoff from a 3-ha granite outcrop in the headwaters; sulfate concentration and temperature increase and alkalinity decreases relative to prestorm conditions. The initial response, however, results from channel interception and groundwater discharge. Rapid rises in the water table level during some storms suggest that macropore flow may play a major role in the hydrologic response of the watershed to rainstorms.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0169-7722(88)90040-X","issn":"01697722","usgsCitation":"Shanley, J.B., and Peters, N., 1988, Preliminary observations of streamflow generation during storms in a forested Piedmont watershed using temperature as a tracer: Journal of Contaminant Hydrology, v. 3, no. 2-4, p. 349-365, https://doi.org/10.1016/0169-7722(88)90040-X.","productDescription":"17 p.","startPage":"349","endPage":"365","numberOfPages":"17","costCenters":[],"links":[{"id":225708,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8936e4b0c8380cd7dd41","contributors":{"authors":[{"text":"Shanley, J.

Sixteen of the cores penetrated sediments as old as Eocene, and several sampled Cretaceous sediments, which allowed us to examine changes in the deuterium content of the oceans with time. Deuterium is shown to be a conservative constituent of the pore water. Its abundance in the pore fluids can be changed by diffusion, but the rate is slow, and corrections for this effect have been made. Changes in the abundance of deuterium can be related to changes in the amount of ice stored in continental glaciers, inasmuch as precipitation in the form of snow is highly depleted in deuterium compared with the oceans. Many of the cores show a change in isotopic composition of samples from early to late Miocene that can be ascribed to the buildup of the Antarctic ice sheets. After correcting for the role of diffusion in reducing the isotopic contrast between samples from a single core, we estimate an increase of 10 per mil (‰) δD (corresponding to a° δ</span><sup>18</sup><span>O change of about 1.2‰) between the early and late Miocene.

In both cases, the Calaveras fault is steep but has a noticeable dip to the northeast and the seismicity does not intersect the surface along the trace of the Calaveras fault in the southern half of the rupture zone. The greatest differences between the two sets of locations was that the locations using the three-dimensional velocity model were deeper, and fewer earthquakes were located within the low-velocity region.

This approach has been used to determine the gravitational stress state as well as the effects of processes such as erosion and temperature changes on the state of lithospheric stress. The major disadvantage of these analyses involves the assumption of lateral constraint which seems unrealistic in view of the observational fact that the crust can deform horizontally in response to applied loads. If the same problems are addressed by assuming that the remote stress state is constant, instead of the condition of zero horizontal deformation, then the resulting stress states are entirely different and in good accord with observations. In the absence of applied tectonic forces the only likely gravitational stress states are those for which all three principal stresses are nearly equal. To the contrary, the gravitational stress states developed on the basis of the lateral constraint assumption can be ruled out. The processes of erosion and sedimentation have slight tendencies to increase and decrease, respectively, the state of deviatoric stress. In particular, for initial stress states in the range of slightly extensional to compressional, erosion has the effect of enhancing the ratio of average horizontal to vertical stress, which may explain, at least in part, the common observation of high near-surface horizontal stresses. Temperature changes have only minor effects on the stress state, as averaged over the thickness of the lithosphere.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB093iB11p13609","issn":"01480227","usgsCitation":"McGarr, A., 1988, On the state of lithospheric stress in the absence of applied tectonic forces: Journal of Geophysical Research Solid Earth, v. 93, no.
