Survivorship And Growth Of Sexually And Asexually Derived Larvae Of Alsophila Pometaria (Lepidoptera: Geometridae), Lawrence G. Harshman, Douglas J. Futuyma

School of Biological Sciences: Faculty Publications

A substantial body of theory is devoted to understanding the relative advantages of sexual and asexual reproduction. It is generally understood that asexual forms potentially have a higher rate of reproduction because they save the cost of producing males. The micro-evolutionary consequences of sexual and asexual reproduction are less clear. Sexual reproduction generates abundant genotypic diversity which may be adaptively advantageous (Williams 1975; Maynard Smith 1978). Asexual reproduction may perpetuate combinations of genes that are co-adapted (Templeton 1979), heterotic (Suomalainen et al. 1976; White 1979), or specialized (Vrijenhoek 1979, 1984). Thus, it is possible that the fitness of a sexual …

Helminth Parasites Of Thomomys Bulbivorus (Richardson) (Rodentia: Geomyidae), With The Description Of A New Species Of Hymenolepis (Cestoda), Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A cestode, Hymenolepis tualatinensis n. sp., is described from the pocket gopher, Thomomys bulbivorus (Richardson) (Rodentia: Geomyidae), from the Willamette Valley in Oregon. Helminths of four additional species were found. Trichuris fossor Hall, 1916, Ransomus rodentorum Hall, 1916, Heligmosomoides thomomyos Gardner and Jasmer, 1983, and Hymenolepis horrida (von Linstow, 1901), of which all but H. thomomyos represent new host records. A significant change in prevalence of the whipworm T. fossor in the population of T. bulbivorus from spring through summer was noted. Significant differences in prevalence of infection of helminths in pocket gophers collected from two different …

Male Effects On Fecundity In Drosophila Melanogaster, Ary A. Hoffman, Lawrence G. Harshman

Lawrence G. Harshman Publications

Effects of male Drosophila melanogaster on female fecundity and productivity were examined, considering both females held in containers with males and females exposed to male effects not involving contact. Females were more fecund when male effects were present, and the largest increase was recorded when vials were previously conditioned by males. This effect was probably due to the growth of transmitted microorganisms, which were observed on the laying surface, as further experiments with vials conditioned by virgin females showed a similar increase in fecundity. A male-specific effect was isolated by conditioning bottles containing only agar with males and virgin females. …

Review Of Prairie Wildflowers: An Illustrated Manual Of Species Suitable For Cultivation And Grassland Restoration By R. Currah, A. Smreciu, And M. Van Dyk, Paul Barnes

Great Plains Quarterly (through 2013)

In recent years, perhaps because of the dwindling virgin prairie in North America, there has been increased public interest in prairie restoration and the cultivation of native species. However, readily accessible information concerning the germination and propagation requirements of many prairie plants, especially the nongrass species or the so-called "wildflowers," has been limited. Prairie Wildflowers is a synthesis of three years of study on the horticultural suitability of more than 140 species of native forbs and shrubs by the University of Alberta Devonian Botanic Garden.

For each species examined, information is given on botanical characteristics (growth habit; flower, fruit, and …

Having A Purpose In Life Western Women Teachers In The Twentieth Century, Courtney Ann Vaughn-Roberson

Great Plains Quarterly (through 2013)

Beginning late in the eighteenth century, social theorists developed an ideology of domesticity, maintaining that women's proper role lay in the care of children, the nurture of the husband, the physical maintenance of the domicile, and the guardianship of both home and social morality.¹ Although this ideology helped to propel females into teaching, historians have not agreed on the impact of domestic ideology on women teachers and on the education profession itself. Some scholars conclude that women's easy access to teaching posts turned the classroom into a workshop for motherhood for the average female, perpetuating anti-intellectualism in education to …

Calmodulin Levels In The Yeast And Mycelial Phases Of Ceratocystis Ulmi, Ganapathy Muthukumar, Rajiv K. Kulkarni, Kenneth W. Nickerson

Papers in Microbiology

The calmodulin content of the yeast and mycelial phases of Ceratocystis ulmi was determined by radioimmunoassay. Calmodulin levels increased at the G1-S boundary of the cell cycle, coinciding with the first visible appearance of buds or germ tubes. However, in both phases the cellular calmodulin levels were equivalent. No differential synthesis was observed.

Eimeria From Bats Of The World: A New Species In Tomopeas Ravus From Peru, Donald W. Duszynski, Linda J. Barkley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two of 17 (12%) crevice bats, Tomopeas ravus (Chiroptera: Vespertilionidae), from Peru had coccidian oocysts in their feces when examined. Sporulated oocysts of Eimeria tomopea n. sp. are ellipsoid to subspheroid, 30.6 x 24.6 (26-34 x 20-28) μm with ovoid sporocysts 13.9 x 9.0 (12-15 x 8-10) μm. A micropyle and substieda body are absent, but polar bodies, oocyst and sporocyst residua, and small, indistinct Stieda bodies are present. The oocyst wall is thick, ≈1.5 μm and consists of 2 layers, the outermost being rough and mammillated. This is only the 13th eimerian to be described from bats worldwide. The …

Lung Cancer Incidence In A Chinese High Background Area — Epidemiological Results And Theoretical Interpretation, Werner Hofmann, Robert Katz, Chunxiang Zhang

Robert Katz Publications

A survey of inhabitant exposures arising from the inhalation of radon and thoron daughters, and lung cancer mortality has been carried out in two adjacent areas in Guangdong province, China, designated as the "high background" and the "control" area. Annual exposure rates are 0.38 WLM/yr in the high background, and 0.16 WLM/yr in the control area, while age-adjusted mortality rates are 2.7 per 105 living people of all ages in the high background, and 2.9 per 105 in the control area. From this data we conclude that we are unable to determine the excess lung cancer rate over normal fluctuations …

Classification, Paleoecology, And Biostratigraphy Of Crinoids From The Stull Shale (Late Pennsylvanian) Of Nebraska, Kansas, And Iowa, Roger K. Pabian, Harrell L. Strimple

Bulletin of the University of Nebraska State Museum (1924–2023)

Thirteen species of crinoids representing the families Diphuicrinidae, catacrinidae, Pirasocrinidae, Erisocrinidae, Cromyocrinidae, Cymbiocrinidae, Scytalocrinidae, and Ampelocrinidae have been collected from the Stull Shale Member of the Kanwaka Formation in the Shawnee Group of the Virgil Series (Upper Pennsylvanian) from near Weeping Water and Plattsmouth, Nebraska, and near Pacific Junction, Iowa. Exposures of the Stull Shale near Melvern, Kansas, have yielded 14 species of crinoids representing the families Diphuicrinidae, Catacrinidae, Pirasocrinidae, Lophocrinidae Allagecrinidae, Cymbiocrinidae, Erisocrinidae, Apographiocrinidae, and Stellarocrinidae. All but two of the species present in the Stull Shale have been previously reported from other stratigraphic horizons, including the Vinland Shale …

The Origin And Distribution Of Clonal Diversity In Alsophila Pometaria (Lepidoptera: Geometridae), Lawrence G. Harshman, Douglas J. Futuyma

Lawrence G. Harshman Publications

A survey of spatial and temporal variation in the frequency of electrophoretically defined genotypes in the geometrid moth Alsophila pometaria revealed a high diversity of uncommon or rare asexual genotypes and clinal distributions of two of the more common clones. There was substantial year-to-year variation in genotype frequencies in seven of eleven sites. Progeny tests have revealed that sexual reproduction is uncommon in two populations and that new asexual genotypes arise from the sexual population. The recurrent origin of asexual genotypes is likely to account for the high genetic and ecological diversity of the asexual contingent of this species’ populations, …

A New Subspecies Of Inca Clathrata (Olivier) From Trinidad, West Indies, And Range Extensions For Inca Clathrata Sommeri Westwood (Coleoptera: Scarabaeidae: Trichiinae), Julius Boos, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

Inca clathrata quesneli is described as a new subspecies from Trinidad, West Indies. New distribution records are given for Inca clathrata sommeri Westwood that extend its range northward in Mexico by approximately 200 km and southward into Colombia and Ecuador in South America west of the Andes. A brief analysis of the historical biogeography of Inca clathrata (Olivier) suggests vicariance (Andean uplift) to explain the separation of the clathrata/sommeri subspecies lineage, and dispersal to explain the separation and isolation of the quesneli lineage on Trinidad and occurrence of sommeri in Mesoamerica.

Tracking Mammals With Fluorescent Pigments: A New Technique, Cliff A. Lemen, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

We have developed a new technique for following the movement of small mammals at night. It entails the use of fluorescent pigments and ultraviolet light. This method allows one to gather extremely accurate information on the location of animals and to trace the movement of individuals for up to 900 m. For much of this distance a detailed record is left by the trail of pigment. It can then be determined which objects are manipulated, what plants are climbed, what burrows are entered and which items are eaten. The use of fluorescent pigments to track animals has two other major …

Feed Requirements For Maintenance And Lactation Of F1 Cows Representing Diverse Biological Types, Larry D. Cundiff, Calvin L. Ferrell, Thomas G. Jenkins

Roman L. Hruska U.S. Meat Animal Research Center: Reports

There are significant differences in weaning weight per cow exposed to breeding among F₁ cow breed groups. (See "Characterization of Breeds Representing Diverse Biological Types: Reproduction and Maternal Performance of F₁ Cows" elsewhere in this report.) These differences are associated with variation among breeds in reproduction, milk production, and growth rate of progeny. Also, there are significant differences among F₁ cows in mature weight. Heavier mature weight is associated with more rapid growth rate of progeny, and heavier weights increase output per cow from the production system when cows are sold. However, it also increases the nutrient …

Sequence Relationships Among Soil-Borne Wheat Mosaic Virus Rna Species And Terminal Structures Of Rna Ii, Y. H. Hsu, M. K. Brakke

Department of Plant Pathology: Faculty Publications

Gel-separated RNAs of the wild-type (WT), Lab 1 and Lab 2 isolates of soil-borne wheat mosaic virus (SBWMV) were transferred to nitrocellulose filters and hybridized with specific cDNA. RNA I, but not RNA II, from all three SBWMV isolates hybridized to cDNA copied from SBWMV WT RNA I. RNA II from all three SBWMV isolates hybridized to cDNA copied from SBWMV WT RNA II, confirming the hypothesis that the Lab 1 and Lab 2 isolates arose by deletion of part of RNA II of WT virions. RNA I1 from SBWMV WT (0∙5L RNA) or from SBWMV Lab 1 (0.35L RNA) …
