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 …

The Impacts Of The Introduced European Green Crab, Carcinus Maenas, On Selected Bivalves And Meiofaunal Communities, Zasha A. Bassett

Dissertations and Theses

This thesis examines the potential impact of the invasive green crab, Carcinus maenas, in Yaquina Bay, Oregon. I sampled the current extent of crab colonization in the intertidal zone of Yaquina Bay using a standardized trapping regimen in selected intertidal sites in August and September 1999. I also evaluated the potential impacts of C. maenas on the commercially important bivalve, Crassotrea gigas. Carcinus' preferred size ranges of C. gigas and other species were experimentally determined. Additionally, Carcinus species preference for C. gigas was examined in relation to two common bivalves, Mytilus trossolus and Macoma nasuta. Experiments were also conducted to …

The Effect Of Leaf Movement On Algal Epiphytes In Seagrass Meadows, T. R. Reid

Theses : Honours

Artificial seagrass units were used to determine whether seagrass leaf movement influences the biomass, species richness and composition of epiphytic macroalgae on the leaves of seagrasses, and whether the influence of leaf movement is altered by the degree of exposure to water movement and to depth. The influence of leaf movement on epiphytic biomass is important from an environmental management perspective, as there is the potential for epiphytic productivity to be underestimated if leaf movement is reducing the standing crop of epiphytes on seagrass leaves. Two forms of artificial seagrass units were used in three experiments to achieve these objectives; …

Biogeography Of A Changing Landscape: Pipidinny Swamp, Yanchep National Park Western Australia, Bradley W. Boucher

Theses : Honours

The resources of Pipidinny Swamp were utilised by the Nyoongar Aboriginal people for possibly 40,000 years. Since the late 1800s, the resources of Pipidinny Swamp were used by non-Indigenous settlers. More recently, the wetland was incorporated in the Yanchep National Park in 1991.This study sought to reconstruct the changes to the natural and cultural environments within the wetland to provide background knowledge for the management board of the Park. Field investigations abo demonstrated the dynamic state of the wetland over a six-month period between low water (Feb-Apr) and high water (Aug-Oct) by monitoring the groundwater system, the vegetation system, and …

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. …

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 …

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 …

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.

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 …
