Morphological Variation In The Southeastern Pocket Gopher, Geomys Pinetis (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The nominal species of southeastern pocket gophers (Geomys pinetis, G. colonus, G. cumberlandius, and G. fontanelus), which collectively occupy a geographic range on the Atlantic and Gulf coastal plain of Alabama, Georgia, and Florida, were examined for morphological variation. Univariate and multivariate analyses were used to determine age, sexual, individual, and geographic variation in G. pinetis. Significant differences were found among different age classes and between sexes. Males displayed higher individual variation than females and external measurements were more variable than cranial measurements. Of the four named species in the pinetis-species group (colonus …

Karyology And Morphometrics Of Three Species Of Akodon (Mammalia: Muridae) From Northwestern Argentina, Rubén M. Barquez, Daniel F. Williams, Michael A. Mares, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Chromosomal and morphometric studies were conducted on a sample from an assemblage of Akodon spp. occurring in various patterns of sympatry from the provinces of Catamarca, Jujuy, Salta, and Tucumán, Argentina. Results showed three distinct morphometric groups based upon size. Size also varied with age, but there were no significant differences in measurements of males and females. The three morphometric groups have distinct karyotypes. Akodon caenosus Thomas is the smallest of the three, and has a karyotype of 2n = 34, FN = 40. A. boliviensis tucumanensis J. A. Allen is intermediate in size and has 2n = 40, FN …

Factors Affecting Insecticide-Induced Resurgence Of The Brown Planthopper, Nilaparvata Lugens On Rice, S. Chelliah, E. A. Heinrichs

Department of Entomology: Faculty Publications

Resurgence of the brown planthopper, Nilaparvata lugens (Stål) on rice was induced by applications of decamethrin, methyl parathion, and diazinon. Differential mortality of predators and hoppers did not appear to be the primary factor for resurgence. Hoppers appeared to be attracted to methyl parathion and decamethrin treated plants because of plant growth. Improved plant growth, however, did not compensate for the increased feeding of the insecticide-treated hopper population, and plants treated with resurgence-causing insecticides succumbed to feeding injury earlier than untreated plants. Population increases were due in part to stimulation of reproduction of the hopper, either by contact action of …

This manual contains detailed descriptions of biological, chemical and physical sampling and analytical procedures used at the Lake Mead Limnological Research Center. The manual was prepared in response to requests made by numerous individuals involved in the Las Vegas Valley Water Quality Program. This manual represents what we consider to be a reasonably complete compilation of methods useful in studying both general and specific limnological questions. While each section is sufficiently detailed to be of use to investigators with little experience in limnological methodology, the methods can be used on a wide variety of lakes and reservoirs, with relatively little …

A Technique For Physiologically Age-Grading Female Stable Flies, Stomoxys Calcitrans (L.), P. J. Scholl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A method of dissection followed by staining was initiated to allow physiological age- grading based on ovarian development in order to more completely describe the physiological development of adult female stable flies [Stomoxys calcitrans (L. )]. The gonotrophic developmental continuum from a non-differentiated cell in teneral females to mature eggs at the time of oviposition was first arbitrarily divided into six stages by using distinct landmarks within the developing oocyte . Then, nulliparous, uniparous, and biparous+ females were differentiated on the basis of the presence or absence of stained follicular relics in the ovariole sheaths. The combination of the …

Ratoon Stunting Disease Of Sugarcane: Isolation Of The Causal Bacterium, Michael J. Davis, A. Graves Gillaspie, Russell W. Harris, Roger H. Lawson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A small coryneform bacterium was consistently isolated from sugarcane with ratoon stunting disease and shown to be the causal agent. A similar bacterium was isolated from Bermuda grass. Both strains multiplied in sugarcane and Bermuda grass, but the Bermuda grass strain did not incite the symptoms of ratoon stunting disease in sugarcane. Shoot growth in Bermuda grass was retarded by both strains.

Seasonal Variations In Water Chemistry And Primary Productivity In Four Alkaline Lakes In The Sandhills Of Western Nebraska, John A. Schnagl

Open Access Master's Theses (through 2010)

Between the Platte and Niobrara Rivers in western and central Nebraska lie over 25,000 square kilometers of dune sand. The dunes have lost their sculptured shapes and windswept edges, being shrouded beneath a mantle of grass and fine loess soil. Only at the blowouts, where wind has cut away this mantle forming cavities in the sides of hills, is the sand exposed.

Dotting this rolling prairie grassland in the depressions between the dunes are small lakes. Over 2000 lakes of widely varied salinities and alkalinities accent the topography of the dunes.

Blue Lake, Roundup Lake, Goose Lake, and Bob’s Lake, …

Dryland Corn Development Under Various Tillage Systems, Wallace Wilhelm

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Corn (Zea mays L.) was grown under dryland conditions in eastern Nebraska to study the influence of tillage practice on plant development and leaf growth characteristics during 1977, 1978, and 1979. Tillage practices used in these experiments were plow, disk, chisel, and no-till. All tillage operations were applied during the spring of each cropping season. Green leaf area increased from emergence through tasseling and then decreased slowly until physiological maturity for all treatments. The maximum green leaf area indices (LAI) averaged 2.14, 2.56, and 1.89 for 1977, 1978, and 1979, respectively. There was no significant tillage treatment effect on …

Phytogeography Of South Padre Island, Texas, Robert I. Lonard, Frank W. Judd

Biology Faculty Publications and Presentations

The phytogeographic affinities of the native flora of South Padre Island, Texas, are analyzed and the probable dispersal agent(s) for each species identified. The native flora consists of 99 species and 44% of the species also occur on the adjacent Texas mainland; 28% of the native species have tropical affinities. Only three species have probably dispersed from the island to the mainland. Two species may be endemic to Padre Island and the Tamaulipan barrier islands. Most of the tropical species have reached the island by oceanic drift, but birds are the most important dispersal agent for the native species. Man …

Growth And Survival Of Nebraska Panhandle Wheat Farms Under Selected Financial Conditions, Larry J. Held, Glenn A. Helmers

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Simulation was used to analyze impact of land expansion alternatives, self-imposed borrowing limits, starting equity conditions, and land appreciation upon a firm concurrently seeking growth and survival over a projected 15-year period (1976-1990). An average-sized 960-acre (389 ha) Nebraska Panhandle wheat-fallow farm served as the representative firm. Standard production practices and technologies were used for computing costs. Machinery and operating costs were assumed to inflate five percent annually. Dryland wheat acreage was valued at $375 per acre ($926.63 per ha) in 1976 and was allowed to appreciate at an annual rate of four percent. A hypothetical series of three cyclical …
