Dissertations And Theses Sponsored By The Department Of Sociology In The University Of Nebraska-Lincoln 1905-1999: Alphabetical And Chronological Lists, Michael R. Hill

Department of Sociology: Faculty Publications

The year 2000 marks the centennial of the formal departmental organization of sociology at the University of Nebraska. The compilations presented here recognize and celebrate the achievements of hundreds of graduate students, my fellow alumni, who have completed masters theses and doctoral dissertations under the auspices of the Department of Sociology. These student works are constructive, often innovative additions to the advancement of knowledge, and several have been abridged in journal articles or published as books (cf., Hill 1988b). The doctoral dissertation, in particular, is a major rite de passage in the transition from student to intellectual (Deegan and Hill …

Molecular Systematics Of The Green Algal Order Trentepohliales (Chlorophyta)., Juan Manuel Lopez-Bautista

LSU Historical Dissertations and Theses

Molecular, karyological, and nuclear genome quantification data from representatives of the order Trentepohliales (Chlorophyta) were used to infer evolutionary relationships with other green algal classes and orders. Phylogenetic analyses of the nuclear-encoded small subunit ribosomal DNA (18S rDNA) sequences from taxa representing all of the major lineages of green algae consistently indicated that the subaerial Trentepohliales are closely related to Ulvophycean marine green algae, particularly to the siphonous and hemisiphonous orders. The phylogenetic distribution of continuous and discontinuous types of mitochondrial large subunit ribosomal RNAs (mtLSU rRNA) in green algae has been shown to be consistent with phylogenetic relationships previously …

A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana., Esra Ozdenerol

LSU Historical Dissertations and Theses

Infant low birthweight rate in East Baton Rouge Parish is higher compared to the nation. Cancer is one of the most serious health problems in Louisiana. A few studies have indicated a relationship between the two health outcomes and their environment, but conclusions from these studies have not always been consistent. The spatial and temporal scales of the data and the methods used in these studies contribute to the inconsistent and uncertain results. The spatial patterns of infant low birthweight and cancer mortality in East Baton Rouge Parish from 1993 to 1996 and their relationships with environmental factors at three …

Ecology Of Seagrass Fishes And Macroinvertebrates On Guatemala's Atlantic Coast., Alejandro Arrivillaga

LSU Historical Dissertations and Theses

The ecology of fishes and macroinvertebrates inhabiting shallow seagrass beds was studied at Bahia La Graciosa, located in Amatique Bay in the Caribbean coast of Guatemala. The study area included extensive turtle grass, Thalassia testudinum, meadows over muddy substrate, whereas a more exposed shoreline also supported turtle grass meadows over sandy substrates outside the bay. A total of 166 samples were collected across two seasons and habitat types in three sampling trips to the area with a cylindrical drop sampler. Diversity and abundance of fishes and macroinvertebrates inhabiting seagrass and adjacent bare-sand sites were described to assess the relative importance …

Spatio-Temporal Distribution Of Larval Gobiosoma Bosc In Waters Adjacent To Natural And Altered Marsh-Edge Habitats Of Mississippi Coastal Waters, J. Read Hendon, Mark S. Peterson, Bruce H. Comyns

Faculty Publications

Larval naked gobies, Gobiosoma bose, were collected monthly from October 1995 to September 1997 by beam plankton trawl from waters adjacent to natural Juncus/Spartina marsh-edge, natural sandy beach and altered Juncus/Spartina marsh-edge habitats in Mississippi coastal waters. Altered marsh habitats consisted of two bulkheaded stations and one stretch of riprap. Abundances were significantly higher in waters adjacent to natural marsh-edge habitats than in those adjacent to altered habitats in year one (P = 0.011), suggesting that the physical nature of alteration may have caused reduced habitat suitability. Abundances also varied seasonally, with summer conditions of high water temperature, increasing tide …

Studying The Expression Of A Novel Microsatellite Mrna In Chironomous Riparius, Mina Ranzurmal

Seton Hall University Dissertations and Theses (ETDs)

The expression of a unique mRNA containing a microsatellite sequence was studied in C. riparius using differential display. First, the rnicrosatellite fragment was sequenced using Sanger's Sequencing method. The microsatellite cDNA contained 11 "ACA" repeats, 12 "AC" repeats, and 5 "CTC" repeats. Second, the affects of cadmium and heat shock on rnicrosatellite mRNA expression were studied. In cadmium experiments, larvae were exposed to low cadmium concentrations (0, 0.04, 0.4, and 4.0 mM) for 24 and 48 h and high cadmium concentrations (0, 1.0, 2.0, 4.0, 8.0, and 16.0 mM) for 48 h. The effects of cadmium on fed larvae at …

The Abundance And Distribution Of Arthropods From Sandstone Outcrops In Coffee County, Georgia, F. Michael Mcaloon

College of Graduate Studies: Theses & Dissertations (1964–2006)

Broxton Rocks Nature Preserve, a 1,233-hectare preserve containing late Pleistocene sandstone (Altamaha grit) outcrops of various sizes and topographies in a conifer-dominated loblolly pine - hardwood forest, represents a unique habitat to the coastal plain of Georgia. Using modified pitfall traps, I sampled arthropods in four subhabitats (bare rock, lichens, ecotone, wiregrass) at Broxton Rocks between January and November 1999. A total of 312,006 arthropods belonging to four classes (Arachnida, Diplopoda, Chilopoda, Insecta) represented by 24 orders was trapped. The numbers of arthropods varied among habitat types, and over the collection dates (P

Assessing The Classification Accuracy Of Digitized National Aerial Photography Program Imagery: Comparison With Botanical Data, Mark Arthur Alexander

Dissertations and Theses @ UNI

The ability to acquire and use remotely sensed data has revolutionized large-scale ecological studies by reducing dependence on difficult and expensive field survey techniques for acquisition of land use and land cover data. Multispectral satellite imagery, typically from the Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and the SPOT High Resolution Visible (HRV) instruments, has proven particularly valuable in surveying and classifying vegetation cover (Frank & Thorn, 1985). Further studies have concluded that alpine vegetation communities and habitats can be mapped successfully by including the geomorphic parameters of elevation, slope, and incidence when classifying remotely sensed data.

This research analyzes …

Factors Affecting The Recruitment Of Riparian Vegetation On The Ord And Blackwood Rivers In Western Australia, Neil Pettit

Theses: Doctorates and Masters

This thesis provides baseline information on the ecological processes involved in the recruitment and regeneration of riparian vegetation. As there has been a paucity of basic ecological studies on riparian vegetation in Australia, the project is broad in scope, and gives a general picture of the factors influencing, the regeneration of riparian vegetation and provides a starting point for more detailed work. The project focuses on factors determining recruitment events and the life history traits of particular species in a river in the cool temperate zone of south western Australia (Blackwood River) and on a river in the dry tropics …

Variability In Winter Mass Balance Of Northern Hemisphere Glaciers And Relations With Atmospheric Circulation, Gregory J. Mccabe, Andrew G. Fountain, Mark Dyurgerov

Geography Faculty Publications and Presentations

An analysis of variability in the winter mass balance (WMB) of 22 glaciers in the Northern Hemisphere indicates two primary modes of variability that explain 46% of the variability among all glaciers. The first mode of variability characterizes WMB variability in Northern and Central Europe and the second mode primarily represents WMB variability in northwestern North America, but also is related to variability in WMB of one glacier in Europe and one in Central Asia. These two modes of WMB variability are explained by variations in mesoscale atmospheric circulation which are driving forces of variations in surface temperature and precipitation. …
