The Progress of Oriole Hybridization in Kansas

Abstract Specimens of Northern ("Baltimore" and "Bullock's") orioles collected at six sites in western Kansas in 1976 and 1978 are compared with specimens collected at the same sites in the mid-1960's. No changes in the location or size of the step-cline ("hybrid zone") between the two taxa are indicated by comparisons of the plumage features of the male specimens; the distribution of phenotypes of birds from sites where both Baltimore and Bullock's orioles occur is not bimodal, and, therefore, there is no indication of selection against intermediate birds. Female Bullock's-like orioles, however, are found farther east along the Cimarron River in southwestern Kansas than they were in the 1960's. The correlations between the amount of precipitation at a locality in western Kansas and the phenotype of oriole that occurs there are high (about 0.90). This suggests that precipitation per se is a factor that determines the distributional limits of these birds relative to each other. There are no recent changes, however, in the average climatic conditions in western Kansas. Perhaps the orioles present at a site in any given season are a reflection of the conditions there the previous season or two. The analyses of size variation among samples collected in the 1970's show an east-west cline that is more-or-less congruent with that found for plumage features; at any given site, the variability in size is positively correlated with the variability in plumage. Where a diversity of oriole phenotypes occurs, there is no tendency for females to associate with males of the "same type" (i.e. Bullock's with Bullock's or vice versa); this suggests that assortative mating does not occur.

Irrigated Cornfields as Habitat for Small Mammals in the Sandsage Prairie Region of Western Kansas

Use of irrigated cornfields by small mammals was investigated in the sandsage prairie region of southwestern Kansas. Nine species were caught in cornfields during one year of sampling. Onychomys leucogaster, Peromyscus maniculatus , and Mus musculus were abundant residents, Perognathus flavescens, P. hispidus , and Reithrodontomys megalotis were resident but less abundant, and Dipodomys ordii was resident only during part of the year. Spermophilus spilosoma and Sigmodon hispidus were transients, whereas Peromyscus leucopus and Reithrodontomys montanus were available but not trapped in cornfields. Richness, evenness, and diversity are given for three habitats sampled (corn, edge areas, and grazed sandsage prairie). Data on relative densities, recruitment, movement, and reproduction are given for the species trapped.

Late Kansan Faunas from Central Kansas

Fossil molluscs and mammals were studied from four late Kansan faunas (Cedar Bluff Canal, Holzinger, Tobin, Wilson Valley) recovered from alluvial fill deposits along the Saline and Smoky Hill river valleys in central Kansas, for which, primarily, only faunal lists had been published more than 25 years ago. A review of the original collections, plus subsequently collected materials, allows us to add 35 taxa to the faunas (9 to Cedar Bluff Canal, 11 to Holzinger, 6 to Tobin, 9 to Wilson Valley). Paleoclimatic inferences drawn from analysis of the faunas suggests that Kansas enjoyed its coolest climate during the time these faunas lived. In addition the central part of the state enjoyed more effective precipitation than at present. Data from the Trego County faunas, which are superposed, suggests a slight warming trend as Gastrocopta cristata and G. procera are present in the younger fauna (Holzinger), whereas Vertigo modesta is present in the older fauna (Cedar Bluff Canal). This relationship plus the presence of G. procera in the Wilson Valley local faunas and the unsubstantiated report of V. modesta in the Tobin local faunas suggests that although the faunas fall within the late Kansan stage they may differ in absolute age among themselves and from the Cudahy local faunas. In an attempt to extend the faunal sequence established by the late Claude W. Hibbard for southwestern Kansas, individuals and field parties from Fort Hays State University have been exploring the late Cenozoic deposits in central Kansas along and between the Smoky Hill and Saline river valleys. Fossils from this area had been collected by parties from the Kansas Geological Survey in the 1930's, but had been subjected to little detailed study. In the course of this work, additional vertebrate material has been obtained

Miscellaneous Summer Records of Birds from Southwestern Kansas

Two summers (1978 and 1979) of field research on nongame wildlife in southwestern Kansas have established several new records for both breeding and migratory species of birds. New breeding records were established for the ferruginous hawk (Buteo regalis), lesser prairie chicken (Tympanuchus pallidicinctus), great-tailed grackle (Quiscalus mexicanus), and the field sparrow (Spizella pusilla) from Morton County; the American avocet (Recurvirostra americana) from Seward and Kearny counties; and the Cassin's sparrow (Aimophila cassinii) from Meade County. Species showing increased summer movements and breeding activities include the curvebilled thrasher (Toxostoma curvirostre), great-tailed grackle, and the Brewers sparrow (Spizella breweri) from Morton County. Sightings of rare species include the ladder-backed woodpecker (Dendrocopos scalaris), northern parula warbler (Parula americana), Blackburnian warbler (Dendroica fusca), and the chestnut-sided warbler (Dendroica pensylvanica) from Morton County; and the rose-breasted grosbeak (Pheucticus ludovicianus) from Grant County. While some species show distributional increases (e.g. great-tailed grackle) others have shown a decline in this region (e.g. ladder-backed woodpecker). Still not enough is known about other species (e.g. rose-breasted grosbeak, field sparrow) to understand their distributional patterns in southwestern Kansas. Several studies describe the status and distribution of summer birds in southwestern Kansas (Rising, 1974; Ely and Thompson, 1971; Graber and Graber, 1951). Recent fieldwork in this region has nevertheless resulted in several new breeding and distributional records. During the summers of 1978 and 1979, while employed by the Kansas Fish and Game Commission, I conducted a nongame research project to 1 Present address: 2924 Lakeside Drive, Oklahoma City, Oklahoma 73120.

This resulted in new breeding records for the curve-billed thrasher, great-tailed grackle, Brewers sparrow, ferruginous hawk, lesser prairie chicken, and American avocet. Other records for species such as the rose-breasted grosbeak, Cassin's sparrow, and the field sparrow serve to help understand their distributions in this region. Included here are records for such species as the ladder-backed woodpecker, northern parula warbler, Blackburnian warbler, and chestnut-sided warbler which are considered rare in southwestern Kansas. The following species deserve close attention by field ornithologists in the future. Ferruginous Hawk. This hawk is an uncommon summer resident in western Kansas with most of the breeding records coming from counties north of the Arkansas River (Johnston, 1964). On 4 June 1979 a nest with two half grown nestlings was discovered in Morton County in far southwestern Kansas. The nest was 10 ft. up in a small stand of trees (Morus) surrounded by Sand sagebrush (Artemisia filifolia)-grasslands. This constitutes the first breeding record of this hawk for Morton County. Lesser Prairie Chicken. This species is reported to be fairly common in the southwestern counties of Morton, Meade, and Ford but actual breeding records from this region are few (Rising, 1974). Two nests of this species were found 2/2 mi. SE of Wilburton, Morton County, in an area of sandhills covered with sagebrush, forbs, and sparse grasses. One nest, discovered on 18 May 1979, was placed beneath a sagebrush on the ground concealed by tufts of new grass. It held 12 eggs. On 1 June 1979 this nest held 12 recently hatched nestlings no more than a few hours old. A nest discovered on 26 May 1979 contained 13 eggs and was placed only 200 yards from the first

Geologic and Economic Significance of the Upper Morrow Chert Conglomerate Reservoir of the Anadarko Basin

The Upper Morrow chert conglomerate is recognized and described for its geologic significance as a new stratigraphic unit and for its economic significance as a reservoir, which has prompted the current deep drilling activity in the Anadarko basin of Texas and Oklahoma. Introduction The Upper Morrow chert conglomerate is a previously unrecognized stratigraphic marker and is one of the most significant gas reservoirs in the western Anadarko basin. It continues to be the object of a widespread exploratory effort in Hemphill and Wheeler counties in Texas and in Roger Mills, Beckham, and Washita counties in Oklahoma. These counties sit astride the axis of the basin and are near the Amarillo-Wichita mountain front (Fig. 1). Drilling to depths greater than 16,000 ft (4900 m) sometimes is required to reach these elusive stratigraphic traps; therefore, knowledge of the depositional environment of these Lower Pennsylvanian Morrow chert conglomerates is necessary to reduce exploratory risk. These chert conglomerates seem to fit a fan delta model, with elongate distributary channels carrying coarse sediments into a shallow marine environment.The reservoir usually is overpressured in the deeper part of the basin and may have a reserve of 1 Bcf/ft (93 million m3/m) of effective porosity on the 640-acre (2.59-km2) drilling unit. Pay thickness may exceed 50 ft (15 m), and deliverabilities of 10 MMcf/D (283 000 m3/d) are not uncommon.Before the discovery of the Shreikey field in Roberts County, TX, in 1974, little was known about the Upper Morrow chert conglomerates except from cores on one or two wells in Hemphill and Roberts counties, TX. Since the Shreikey discovery, this zone has prompted much of the deep exploratory drilling in the basin, with successful efforts in fields such as Buffalo Wallow, Reydon, Cheyenne, Elk City, and in recent discoveries. Regional Setting The Anadarko basin covers an area of approximately 35,000 sq miles (90 000 km2) stretching across northwestern Oklahoma, the northeastern Texas Panhandle, southwestern Kansas, and southeastern Colorado. The Morrow chert conglomerates are confined to a relatively small area in the eastern Texas Panhandle and western Oklahoma (Fig. 2). The basin is asymmetrical with its short limb and axis adjacent and parallel to the northwest-southeast trending Amarillo-Wichita uplift. This leads to an easy subdivision into mountain front, basin axis, and shelf area.Major orogenic movements occurred in late Devonian, post-Mississippian/pre-Morrowan, and post-Morrowan/pre-Des Moinesnian time, with the latter episodes producing most of the tectonic features of the area, including uplift, folding, and erosion of the Amarillo-Wichita Mountains and frontal area. The axes of faulted anticlines trend subparallel to the major uplift. JPT P. 489＾

Late Prehistoric Settlement Patterns in Southwestern Kansas

During the summer of 1975, an intensive ar cheological site survey was carried out by the University of Kansas in the Cimarron National Grassland, southwestern Kansas, for the U.S. Forest Service. Work focused on the recovery of data to enable the determination of site functions in order to develop a predictive model of prehistoric site locations for the High Plains of western Kansas. Eight functional site types were derived from analysis of recovered stone tools and fauna remains. Analysis of site physiographic data with respect to site functions made it apparent that landform, the availability of water, and raw materials are resources which had a statistically significant effect on prehistoric site location strategy in southwestern Kansas. Moreover, for functional site types some physiographic variables are more important than others. It is suggested that the results of this study are applicable to other portions of the High Plains.

Application of Solar Energy to Producing Operations of Oil and Gas Fields

Using solar energy to generate limited electrical power for cathodic protection of well casing in the Hugoton and Panoma Council Grove fields protection of well casing in the Hugoton and Panoma Council Grove fields of southwestern Kansas has proved effective. The feasibility of a similar power source for supervisory control systems is being tested in Wattenberg power source for supervisory control systems is being tested in Wattenberg Field, CO. Introduction The basic problems wereto provide better cathodic protection for the casing of 516 old (drilled before 1948) protection for the casing of 516 old (drilled before 1948) Hugoton Field and 125 new Panoma Council Grove Field gas wells than was possible with magnesium anodes, andto provide die supervisory control system used for deliquefying the gas wells with limited electrical power. Cathodic Protection Cathodic protection is required in the Hugoton and Panoma Council Grove fields in Kansas to eliminate Panoma Council Grove fields in Kansas to eliminate corrosion of bare well casing exposed to the highly corrosive water of the Glorietta formation. The cathodic protection cur-rent provided by the magnesium anode protection cur-rent provided by the magnesium anode beds during the past 20 years was not completely adequate. The casing-leak history curve (Fig. 1) shows that casing-leak frequency was reduced by 1963 after magnesium anodes had been installed on 505 wells. However, even though the leak frequency was reduced (64 leaks were experienced instead of the 105 forecast), the 23 leaks experienced during 1963-76 indicated the magnesium anodes were inadequate. This was partially because anodes degrade with time to a zero output in about 10 years. Thus, the level of protective current ranges from an initial high of 1 down to 0 A, with a lifetime average of 0.35 to 0.5 A. Casing-potential profile surveys indicated that the wells actually required a minimum of 1.5 A of current for adequate cathodic protection and confirmed our conclusion drawn from the casing-leak history curve that the magnesium anode beds were inadequate. In 1974, a study was made to determine if an alternative source of direct current power was available, since a major portion of the original magnesium anode beds was expended. Most locations lacked electrical power; if power for a conventional rectifier-powered power; if power for a conventional rectifier-powered cathodic protection system could be brought in, the minimum monthly charge for 5 years would have been as much as $30 for less than $1 worth of power. Thus, an alternative was needed. Thermoelectric generators had been tried unsuccessfully; wind chargers would require excessive maintenance; and a successful turbo generator operated by low gas flow had not been developed. Thus, silicon-cell solar panels with lead-acid storage batteries appeared to be the logical solution, if economically feasible. Comparing solar costs with magnesium anode beds for a 30-year period (Table 1) indicated that solar power systems were economically feasible and could power systems were economically feasible and could provide adequate cathodic protection, thus eliminating provide adequate cathodic protection, thus eliminating casing leaks and the resulting costs to repair or replace the wells. Therefore, a 6-month test of 30 solar-powered cathodic protection systems began Oct. 1974. These installations performed flawlessly after initial problems were corrected. JPT P. 151

Bovine Virus Diarrhea (BVD) Vaccination

Bovine viral diarrhea (BVD) was first reported in 1946, or approximately 30 years ago, yet there is still confusion and lack of understanding of this disease. It is difficult to find general agreement on any part of this disease entity from vaccination to titer. Despite the confusion, most people have definite opinions about the disease, including the use of vaccine. The majority of feedlot cattle in southwestern Kansas receive an intramuscular inoculation of BVD vaccine when they enter feedlots . Recently, some oral BVD vaccine has been used. This trial was to compare oral and intramuscular BVD vaccine in stressed calves. Rate of gain, feed consumption, and feed efficiency were not influenced by BVD vaccine administration (Table 1). This was an anticipated response, as initial BVD titers indicated calves had not been previously exposed to BVD. BVD vaccine administered orally did not increase titers at 42 days after inoculation. But when it was administered intramuscularly, five steers had BVD titers exceeding 1 :4. Sickness was held to a minimum and no calves died.

On estimating the sensible heat flux over land

The sensible heat flux from a land surface can be estimated from the ground temperature, and the air speed and air temperature at a single height in the surface layer. To test this technique, a study was made over a newly-planted wheat field in southwestern Kansas. Hourly averages of the sensible heat flux were calculated for a two day period. The data consisted of infrared measurements of the ground temperature, and of wind speed and air temperature measurements made at 1.5 m. The results obtained were in close agreement with sensible heat flux calculations derived from profile measurements of wind speed and air temperature made concurrently at the same site.

Evaluating soil moisture and yield of winter wheat in the Great Plains using Landsat data

Locating areas where soil moisture is limiting to crop growth is important for estimating winter-wheat yields on a regional basis. In the 1975–76 growing season, we evaluated soil-moisture conditions and winter-wheat yields for a five-state region of the Great Plains using satellite (Landsat) estimates of leaf area index (LAI) and an evapotranspiration (ET) model described by Kanemasu et al. (1977). Because LAI was used as an input, the ET model responded to changes in crop growth. Estimated soil-water depletions were high for the Nebraska Panhandle, south-western Kansas, southeastern Colorado, and the Texas Panhandle. Estimated yields in five-state region ranged from 1.0 to 2.9 metric ton/ha.

Oil and Gas Developments in North Mid-Continent in 1974

Iowa drilling activity during 1974 consisted of 4 exploratory holes, all dry, and 220 holes drilled by gas-storage companies. Crude oil production in Kansas during 1974 (61,690,731 bbl) dropped 6.8% below the 1973 level. The state's refineries processed 133,632,586 bbl, which was more than twice its production. Natural gas production (894,307,867 Mcf) decreased 1%. Drilling increased 25% from the 1973 figure, with 2,825 holes reported; 51% of the holes drilled for oil or gas were successful. Panoma gas area, in southwestern Kansas, had 146 of the 389 gas-well completions. Nebraska, with 230 holes, had 30% more completions in 1974 than the year before. Drilling was primarily in the Denver basin and Chadron arch areas. Thirteen field discoveries, continued expansion of Bush Creek field, Hitchcock County, and a Dundy County discovery highlighted Nebraska drilling. Exploration by deep tests in the Forest City basin and by shallow holes in the southwestern part of the state were Missouri's main areas of interest in 1974. No tests were drilled for oil or gas in Minnesota and Wisconsin.

Controlling Greenbugs In Grain Sorghum with Foliar and Soil Insecticides

Various foliar and soil insecticides to control C-biotype Schizaphis graminum (Rondani) on grain sorghum were studied during 1972–73 in southwestern Kansas. Single applications of most foliar sprays effectively reduced greenbug populations in dryland sorghum, but residual activity varied. Lower rates of disulfoton, oxydemetonmethyl, dicrotophos, phosalone, Monitor® (O S-dimethyl phosphoramidothioate, BayHox 1901 (2-[(ethylthio)methyl]-phenyl methylcarbamate), and Dyfonate® (O-ethyl S-phenyl ethylphosphonodithioate) were as effective as higher rates with no significant differences between them. Foliar treatments significantly increased sorghum yields in 1973 by reducing greenbug numbers. Most applications of soil systemic insecticides significantly reduced greenbug populations over the check. Plots treated with disulfoton granules had the fewest greenbugs. All soil systemic insecticides increased grain yields in 1973 by lowering greenbug populations, but only disulfoton, Diamond Shamrock DS-15647 (3,3-dimethyl-1-(methylthio)-2-butanone-O-[(methylamino)carbonyl] oxime), and carbofuran increased yields significantly. No insecticide tested reduced plant stands.

Observations of the Naturalization of Pinus in Kansas

In a few rare cases reported here, several species of pines introduced into Kansas have produced viable seed and wild seedlings as they reach reproductive maturity. This report covers all known cases of reproduction of pines in Kansas over a 7 year period, and attempts to identify the factors leading to successful establishment. Trans. Kans. Acad. Sci., Vol. 77 (3), 1974. Botanists and taxonomists agree that within the limits of recorded history there are no representatives of the genus Pinus in Kansas. Historic taxonomic works of the State and the Great Plains region show that, of the order CONIFERALES subdivision Gymnospermae, the only species is eastern redcedar (Juniperus virginiana L. : Cuppressaceae). Mirov (2) has reported that leaves and cones of Pinus quenstedti Heer, a long extinct species of the Cretaceous period, were located in Southwestern Kansas by Lesquereux in 1883. I have found no other record of natural historic or prehistoric pines in Kansas. The report of this species may hold paleobotanical importance but is of no apparent significance in recent times. Whatever the reasons for the absence of pinus from the native flora of Kansas, the purpose here is to report the few known cases of volunteer reproduction of certain introduced pine species. Extensive travel throughout Kansas by field foresters during the past decade has provided the opportunity to investigate numerous pine plantations of reproductive age; but those listed in the table are the only known cases of volunteer reproduction. Pines have been planted in Kansas since the time of the earliest settlers. Though many of the early plantings were of only a few trees and many were probably unsuccessful, there are scattered remnants of some old plantings which originated nearly 120 years ago. Additionally, there are increasingly large numbers of pine plantings of younger ages still surviving. A list of the species of pines that have been observed to produce volunteer seedlings are shown in Table 1. In all cases, the trees were planted in groves or rows of six or more, probably from only one original source. The reproductive performance of some species is quite significant, notably the white, Austrian, Scots, and red pines. In the case of Ponderosa pine, it is remarkable that the only instance of reproduction was noted in an old provenance test plot on the grounds of the Forestry Building at Manhattan. The records of this planting have been lost, but it was planted in 1942 as a replicated test of performance of this species from over 30 geographic sources.

Oil and Gas Developments in North Mid-Continent in 1973

Crude-oil production in Kansas during 1973 (66,227,391 bbl) dropped 10.2% below the 1972 level. Double that amount (136,077,943 bbl) was refined in the state. Natural-gas production (902,189,763 Mcf) increased only 0.4%. Drilling decreased 14% from the 1972 figure, with 2,114 holes reported; 47.5% of the holes drilled for oil or gas were successful. Panoma Gas area, in southwestern Kansas, had 186 gas-well completions. A significant discovery was made in the Kansas part of the Salina basin. Nebraska, with 161 holes had 45% fewer well completions in 1973 than in 1972. Drilling was concentrated again in the Denver basin, and 42.6% of the development wells were successful. Six field discoveries and expansion of an old Hitchcock County field highlighted Nebraska drilling. Mis ouri's Forest City basin was the main exploration target in that state, but tests were dry. Iowa drilling activity was limited to 208 holes drilled by gas-storage companies. No tests were drilled for oil or gas in Minnesota and Wisconsin.

Stratigraphic Trap Accumulation in Southwestern Kansas and Northwestern Oklahoma

An oil- and gas-bearing inlier of Morrowan sandstones presents a paradoxical situation in that water, oil, and gas are present in an inverted structural relation, some of the gas being structurally lower than oil and water. A map of the pre-Pennsylvanian topography reveals that a modified trellis drainage system was developed on subaerially exposed Mississippian strata. Southwestward-tilted resistant limestones of the Chesterian Series stood out as subparallel cuestas; intervening erosional valleys developed on interbedded nonresistant shales. Morrowan strata were deposited under conditions of cyclic marine southwest-to-northeast transgression, which was interrupted by several minor regressions. Sands were deposited during the regressive phases, and shales during transgressive phases. Small-scale structural noses and closures on the Inola limestone are largely the result of differential compaction of shales deposited over buried pre-Pennsylvanian topography. Detailed mapping affords a logical explanation for each producing well and all but a few dry holes in the Second Morrow sand of the Harper Ranch field of Clark County, Kansas. The anomalous distribution of some gas accumulation is explained by Gussow's principle, modified to apply to a stratigraphic trap.

Historical Biogeography of the Gray Fox (Urocyon cinereoargenteus) in Kansas

Early published accounts of the gray fox documented its presence in at least the forested regions of easternmost Kansas at the time of settlement of the territory by European man. These accounts suggested that the species generally was rare in the state during the early decades of the 1900's, but that it was becoming more common by about mid-century. Westward dispersal of the species in Kansas apparently was restricted by the Flint Hills. Once that barrier was crossed, by means of riparian communities along the Kansas River, the gray fox began dispersing westward across the northern half of the state in the ribbons of forest that border the principal tributaries of the Kansas River. Movement of the species into south-central and southwestern Kansas apparently was from the south, by means of riparian communities along the Arkansas River and one of its tributaries, the Cimarron River. Trans. Kans. Acad. Sci., Vol. 77 (4), 1974. The gray fox (Urocyon cinereoargenteus) occurred in at least easternmost Kansas at the time of settlement of the region by European man (Knox, 1875:19). Black (1937:166) described the known distribution of the species in the state as east of the Flint Hills.... Other researchers (e.g., Lantz, 1905:177; Kellogg, 1915; Hibbard, 1933:236; Hibbard, 1944:70) of the first half of the twentieth century commented briefly on the scarcity of the gray fox in Kansas, but added little else to what already had been reported (see above). Cockrum (1952:236) reiterated that the species was nowhere common in the state . ., and pointed out that Only three records of the gray fox being taken in Kansas since 1900 are available, one specimen taken in. . . 1914, one in ... 1949, and

A Range Extension and Addition to the Herpetofauna of Kansas

The lined snake (Tropidoclonion liheatulm) is' represented in Kansas by two subspecies, T. 1. I;neatum from extreme northeast Kansas and T. 1. annectans to the south and west (Smith, 1956). The most western records for this species in Kansas are for two specimens' recorded by Legler (1960) from Barber County in south-central Kansas, and for one from Rooks County in the north-central part of the state (Smith, 1956). On the weekend of 2-3 September 1972, Richard Plumlee and Ronald Clendenin (both students at the University of Kansas) collected an adult male Tropidoclonion lineatunm ca. 7 mi N Ashland on Kansas Rt. 94 in Clark County, southwestern Kansas. Other reptiles found in association with this specimen at the Clark County locale were Diadophis punctatus aryi, Sonora e. episcopa, and Sceloporls undllatiis garmani. The specimen of T. lineatlum (Museum of Natural History at the University of Kansas-KU 148462) represents a range extension for the species of ca. 150 mi (airline) SSE of the Rooks County record, over 75 mi (airline) W of the Barber County locality, and ca. 125 mi (airline) NW of the nearest known record in Oklahoma (Webb, 1970). In addition, the Clark County locality is ca. 175 mi (airline) E of the nearest record for the disjunct populations of this species found in New Mexico, Colorado, and the extreme western Oklahoma panhandle.
