Oviposition Behavior Partitions Aquatic Landscapes Along Predation And Nutrient Gradients, C. A. Binckley, W. J. Resetarits Jr.

Biological Sciences Faculty Publications

That individuals attempt to minimize the ratio of mortality risk/growth rate (μ/g) when foraging within individual habitat patches is well established. Do species partition among spatially discrete communities embedded in complex landscapes in a similar manner? We investigated how 3 ovipositing species (2 Hyla treefrogs and a hydrophilid beetle, Tropisternus lateralis) responded to simultaneous gradients of nutrients and predation risk. Species partitioned our experimental metacommunity primarily by reducing oviposition with fish. Tropisternus positively responded to increased nutrients, but the effect decreased with increasing risk, as predicted by μ/g theory. Use of fish habitats by Tropisternus was unrelated to breeding …

Simpler Mode Of Inheritance Of Transcriptional Variation In Male Drosophila Melanogaster, Marta Wayne, Marina Telonis-Scott, Lisa Bono, Lawrence G. Harshman, Artyom Kopp, Sergey V. Nuzhdin, Lauren Mcintyre

Lawrence G. Harshman Publications

Sexual selection drives faster evolution in males. The X chromosome is potentially an important target for sexual selection, because hemizygosity in males permits accumulation of alleles, causing tradeoffs in fitness between sexes. Hemizygosity of the X could cause fundamentally different modes of inheritance between the sexes, with more additive variation in males and more nonadditive variation in females. Indeed, we find that genetic variation for the transcriptome is primarily additive in males but nonadditive in females. As expected, these differences are more pronounced on the X chromosome than the autosomes, but autosomal loci are also affected, possibly because of X-linked …

Yosemite Butterflies (Text), 2nd Edition, Kenneth E. Davenport

The Taxonomic Report of the International Lepidoptera Survey

The author, Kenneth E, Davenport, has collected or observed butterflies extensively in the Yosemite region (at least 90 collecting or observation days) since August 1963. Information for this study began with Davenport obtaining a copy of Garth and Tilden’s 1963 Yosemite Butterflies in 1970. The annual Season Summaries for California published in the News of the Lepidopterists’ Society between 1975 and 2006 have been checked for records. The common English and scientific names used in this publication mostly follow the names used by the International Lepidoptera Survey (TILS) except in a few cases.

The Long Term Effect Of Time-Memory On Forager Honey Bee (Apis Mellifera) Recruitment., Matthew Walter Otto

Electronic Theses and Dissertations

Experiments were performed to determine the influence of the honey bee time-memory on a forager bee's sensitivity to recruitment. Two groups of foragers from one colony were trained to separate food stations at the same restricted time of day for several consecutive days. Feeding then was canceled at one station but continued for four more days at the other. Bees with more days of training at a non-productive source were significantly less likely than foragers with less training to be recruited to an alternative food source presented at the same time of day. Furthermore, the ability of a forager to …

Modeling Of Culicidae Population Capacity Using Remote Sensing, Gis, And Fractal Geometry, Daniel Patrick Johnson

All-Inclusive List of Electronic Theses and Dissertations

A remote sensing and fractal geometric approach is proposed for the surveillance of mosquito population. The spread of vector-borne pathogens is becoming increasingly important with recent discussions of extensive human urbanization and global climate change. To date most studies dealing with mosquito transmitted disease surveyed by remote sensing and Geographic Information Systems have been conducted in tropical homogenous locales. This study approached the issue in a rapidly suburbanizing county in the Midwestern portion of the United States. Adult mosquitoes were trapped over a several year period and the landscape of the surrounding patches analyzed via remote sensing, fractal geometry, and …

A Description Of A New Subspecies Of Lycaena Phlaeas (Lycaenidae: Lycaeninae) From Montana, United States, With A Comparative Study Of Old And New World Populations, Steve Kohler

The Taxonomic Report of the International Lepidoptera Survey

The Palaearctic, Oriental, and Ethiopian Region subspecies of Lycaena phlaeas are briefly discussed. A more detailed account of the North American subspecies is presented, and a new subspecies, L. p. weberi, from the Sweet Grass Hills, Montana is described. The possibility that the eastern United States subspecies hypophlaeas was introduced from the Old World is discussed; however no conclusion can be reached with certainty. The relationship between Old World and New World subspecies of L. phlaeas is discussed. Evidence presented supports the treatment of New World populations as subspecies of L. phlaeas.

Preliminary Notes On Tachinidae Reared From Lepidoptera In The Ecuadorian Andes, John O. Stireman Iii

Biological Sciences Faculty Publications

Current estimates of the species richness of Tachinidae among geographical provinces suggest that the Neotropical Region harbors the largest number of species and represents a geographic epicenter of tachinid diversification (O’Hara 2006). The Neotropics boasts an impressive fauna consisting of 2864 described species belonging to 822 genera at the time of the Neotropical catalog (Guimarães 1971), making it almost twice as species rich as any other geographic realm (O’Hara 2006; Stireman et al. 2006). This diversity is most apparent at middle elevations (1000– 2000m) along the mountain chains of tropical Central and South America, where tachinids are an abundant and …

Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar

School of Natural Resources: Faculty Publications

Predicting the spatial foci of zoonotic diseases is a major challenge for epidemiologists and disease ecologists. Migratory birds are often thought to be responsible for introducing some aviozoonotic pathogens such as West Nile and avian influenza viruses to a local area, but most information on how bird movement correlates with virus prevalence is anecdotal or indirect. We report that the prevalence of Buggy Creek virus (BCRV) infection in cimicid swallow bugs (Oeciacus vicarius), the principal invertebrate vector for this virus, was directly associated with the likelihood of movement by cliff swallows (Petrochelidon pyrrhonota), an amplifying host …

Ecological Correlates Of Buggy Creek Virus Infection In Oeciacus Vicarius, Southwestern Nebraska, 2004, Amy T. Moore, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown

School of Natural Resources: Faculty Publications

Buggy Creek virus (family Togaviridae, genus Alphavirus, BCRV) is an alphavirus within the western equine encephalitis virus complex whose primary vector is the swallow bug, Oeciacus vicarius Horvath (Hemiptera: Cimicidae), an ectoparasite of the colonially nesting cliff swallow, Petrochelidon pyrrhonota, that is also a frequent host for the virus.We investigated ecological correlates of BCRV infection in 100-bug pools at 14 different swallow colony sites in southwestern Nebraska from summer 2004, by using plaque assay on Vero cells to identify cytopathic virus and reverse transcription-polymerase chain reaction to identify noncytopathic viral RNA. We found 26.7% of swallow bug pools …

The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander

Faculty Research & Creative Activity

The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …

Termite Resource Partitioning Related To Log Diameter, Deborah A. Waller

Biological Sciences Faculty Publications

The termites Reticuliterines virginicus and R. flavipes are sympatric in forests along the eastern United States from Florida to Maryland. These congeners construct subterranean nests, forage on surface and buried wood, and appear to have very similar ecological requirements. In the present study, I examined host-wood selection by these species in a coastal forest over two years. Logs inhabited by R. virginicus had significantly greater diameters than those used by R. flavipes. It is not known whether this pattern resulted from species-specific differences in preference for host size or competition for preferred logs. Host-wood temperature did not differ for …

Odonates At The Clark County Wetlands Nature Preserve: A Look At Habitat And Relative Abundance, Erin Jolley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study is to identify the various species, relative abundance and habitat of dragonfly and damselfly larvae at the Clark County Wetlands Park Nature Preserve (WPNP). An accurate assessment of these insects can be useful in interpreting potential indications of environmental problems at the Wetlands. From this data, necessary improvements can be made to the dragonfly habitat as well as the habitat of other surrounding organisms. Habitat identification is considered especially important because it is "structured by instream and surrounding topographical features, and is a major determinant of aquatic community potential" (Southwood, 1977). For purposes of this …

Comparative Pollen Foraging Of Africanized And European Honeybees In A Non-Agricultural Environment, Ruben Ruiz

Theses and Dissertations - UTB/UTPA

With the advent of the Africanized honeybee, ways to differentiate it from the European honeybee have been greatly sought in attempts to better understand the role of Africanized bees in pollination. Pollen collecting strategies for both honeybee subspecies have been explored in attempts to exploit their pollinating capabilities. This project examined pollen collected by honeybees from feral and managed European and Africanized colonies in a relatively isolated site. Paired European and Africanized honeybee colonies were used to obtain pollen foragers. Through acetolysis (series acidified Acetic Anhydride washings); the collected pollen from the individual foragers was treated and observed with light …

Tapeworms Of Elasmobranchs (Part Ii) A Monograph On The Diphyllidea (Platyhelminthes, Cestoda), Gaines Albert Tyler Ii

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

The main objective of this monograph was a synthesis of the available knowledge on the diversity, systematics, host associations, and biogeography of the Diphyllidea. A thorough review of the literature resulted in the transfer of Diagonobothrium into Diphyllidea as a genus inquirendum. The genus Yogeshwaria was also transferred to Diphyllidea as a synonym of Echinobothrium. Its only species, E. nagabhushani n. comb., is considered to be a species inquirenda. New collections resulted in the description of a new species of Echinobothrium. Type and/or voucher specimens for 32 of 36 valid diphyllidean species (including the new species) …

Hyla Squirella (Squirrel Treefrog): Refugia., Louis A. Somma, David Serrano

Papers in Herpetology

HYLA SQUiREUA (Squirrel Treefrog). REFUGIA. Entomologists commonly use trap-nests to monitor cavity-nesting Hymenoptera. These trap-nests consist of 5 x 10 cm pine timber cut into 12-cm lengths. Five lengths are then stacked and strapped together. Each pIece of timber is predrilled in each side to have either a 3.2, 4.8, 6.4, 7.9, or 12.7 Iiundiameterhole, 8 cmindepth. Thus, each trap-nest consisted of five pieces of wood containing 2 holes of each diameter. They are suspended with wire from tree trunks and branches. We set these wooden traps (N = 10) at Devil's Millhopper Geological State Park, Gainesville, Alachua Co., Florida, …

Celastrina Serotina (Lycaenidae: Polyommatinae): A New Butterfly Species From The Northeastern United States And Eastern Canada, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

A new light-venter Azure species, Celastrina serotina, is described from the northeastern United States and eastern Canada. The flight period of this univoltine spring species is interpolated (allochrony) between its sympatric congeners, C. lucia Auctorum (not Kirby) and C. neglecta (Edwards). In this regard it is similar to C. neglectamajor Opler & Krizek in the southern Appalachians and C. idella Wright & Pavulaan on the New Jersey coastal plain. In a significant portion of its range, C. serotina larvae feed on eriophyid mite-formed galls on the upper surface of Black Cherry Prunus serotina Ehrh. …

Biodemography Of A Long-Lived Tephritid: Reproduction And Longevity In A Large Cohort Of Female Mexican Fruit Flies, Anastrepha Ludens, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Damla Senturke, Lawrence G. Harshman

Lawrence G. Harshman Publications

Age of sexual maturity, daily and lifetime reproductive rates, and life span were recorded in a laboratory cohort of Mexican fruit flies consisting of over 1100 females maintained individually. The results revealed that, relative to the medfly, the Mexfly is slower maturing (14 vs 17 days), more fecund (1400 vs 650–1100 eggs/female), and longer lived (50 vs 35 days). The results reinforced the generality of several earlier findings on the medfly including the deceleration of mortality at older ages and the weakness of the correlation between the rate of egg laying at early ages and both subsequent reproduction and remaining …

The Symmetry Of Longevity, Lawrence G. Harshman, Hans-Georg Müller, Xueli Liu, Yue Wang, James R. Carey

Lawrence G. Harshman Publications

We tested the hypothesis that relatively symmetrical flies live longer. Vein measurements on the left and right wings from the same individual were used to characterize bilateral symmetry in relationship to age-specific survival in defined cohorts. A longitudinal cohort study supported the hypothesis of a correlation between bilateral symmetry and longevity. For another type of experiment, wings were removed from females and males at approximately the beginning of adult life. Thus, there would be no effect of wings per se on adult survival. These wings were measured to characterize bilateral asymmetry, and the day of death of each dewinged individual …

Taxonomic Analysis Of The Genus Megisto (Satyridae) In The Eastern United States, Part I: Types, Type Localities, And Taxonomic Relationships Of The Available Names, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The genus Megisto Hübner, 1819 in the eastern United States and southeastern Canada is currently comprised of the original epithets Papilio eurytus Fabricius, 1775, Papilio cymela Cramer, 1777, Papilio eurytris, Fabricius, 1793, and Neonympha eurytris viola Maynard, 1891. Because the eastern Megisto is considered by some, including the present author, to contain two or more sibling species, the types and type localities of each of these names were studied. Where no type was found and no type locality fixed, typification was established by lectotypification or neotypification and a type locality was fixed. The taxonomic relationship of these taxa were …
