Determinants Of Variation In The Response Of The Aphid Parasitoid Aphidius Ervi To Aphid Sex Pheromones, Nisreen Kutiech

School of Biological and Marine Sciences Theses

Variation in parasitoid responses to semiochemicals may be influenced by genetics, phenotypic plasticity and the individual's physiological state. Previous experimental work has indicated a high degree of variability among parasitoid individuals in their response to aphid sex pheromones but no work has been done to investigate the factors behind such variation. Some aspects of this variation were investigated in the aphid parasitoid Aphidius ervi (Haliday) (Hymenoptera: Braconidae) in the laboratory. Conducting behavioural experiments, the searching behaviour of females was investigated in the presence and the absence of the aphid sex pheromone (4GS,7S,7a/?)-nepetalactone, observing the same individual female parasitoids during two …

Software Curating : The Politics Of Curating In/As (An) Open System(S), Joasia Krysa

School of Biological and Marine Sciences Theses

The thesis examines how Information technologies have changed the practice of curating. It proposes an Interdisciplinary approach that directly links curating (often understood as an activity of artistic programming), computing (the activity of computer programming) and a relatively recent Interest In software art (in which programming Is understood as artistic practice). Although there Is much contemporary critical work and practice that Is described as art-oriented programming or software art, the thesis aims to explore a perceived gap In discussions around software curating. Curators working with online technologies are presented with the challenge of how to respond to new artistic forms …

Factors Affecting The Production Of Fermented Moist Feed For Chickens And Effects On The Gastrointestinal Environment, Aziwo Tatanja Niba

School of Biological and Marine Sciences Theses

Fermented feed technology is a biosafe method of feed preparation and fermentation improves feed quality. Factors affecting lactic acid production in fen-nented moist feed for chickens and the influence of fermented feed on the gastrointestinal environment of chickens were investigated. Water quality was observed to affect lactic acid production in fermentation of cereals (maize, sorghum, wheat and barley). The presence of calcium carbonate in the fermentation mixture significantly (P<0.01) reduced lactic acid production from maize, sorghum and wheat. Grain particle size did not significantly affect feed fermentation as biosafe concentrations of lactic acid (>150mmol/L) were obtained from fermentation of coarse grain particle sizes. Differences in polyphenols content of red and white sorghum varieties did not have a significant effect on 24-hour lactic acid production …

Gomphonema Parvulum (Kutzing) Kutzing: Ecophysiological, Morphometric And Observational Studies Of A Species Complex, Dawn Titiannia Rose

School of Biological and Marine Sciences Theses

Perturbations to environmental conditions experienced by any one species, can invoke a physiological and/or behavioural response that may be expressed morphologically and ecologically. This has important implications for diatom taxonomy and the use of diatoms as environmental indicators. The reliable recognition of a taxon with a particular life history, morphology, ecology and physiology may necessitate the adoption of narrower species concepts than those in current floras. This would have the advantage of clarifying the ecological ranges of taxa used in biological monitoring programmes. Gomphonema parvulum has long been a taxonomic problem. The species exhibit considerable is found over a wide …

Biodiversity And Ecosystem Functioning: Experimental Tests Using Rockpools As A Model System, John N Griffin

School of Biological and Marine Sciences Theses

How anthropogenic changes to species composition and diversity are likely to affect the properties of the ecosystems of which they are an integral part, and by extension the goods and services humans derive from them, is a key question in ecology. Despite over a decade of vigorous empirical research and theoretical developments, there remain many unknowns. Using intertidal rockpools and laboratory marine mesocosrns, I used a variety of approaches to address several of these relatively poorly studied issues. In particular, the work presented here focused on the relative roles of species composition and richness, as well as the extent to …

Phenotypic Plasticity In Marine Intertidal Gastropods, Ahmed Mohammed Al-Mazrouai

School of Biological and Marine Sciences Theses

Phenotypic plasticity, the differential phenotypic expression of the same genotype in response to different environmental conditions, is a paradigm central of the study of evolution and ecology and is at the core of the "nature versus nurture" debate. Here, the marine gastropod Littorina littorea was used as a model to further our understanding of the potential role of phenotypic plasticity in intertidal systems. In the first study L. littorea was included in an investigation of induced defences across six species of intertidal marine gastropods in the families Littorinidae and Trochidae. Species differed in the magnitude and type of plastic response, …

Proteomics And Ecotoxicoldgy:.Marine Invertebrates And Endocrine Disrupting Chemicals, Anne Bjornstad

School of Biological and Marine Sciences Theses

The key problem faced by environmental scientists is to predictand recognize the damaging effects of chemical pollutants on natural biota. The aim of this thesis was to evaluate the potential for proteomics in ecotoxicology and environmental risk assessment (ERA), with the hypothesis that proteomic technologies (i.e. ProteinChip technology in combination with SELDI TOF MS) could be a useftil supplement to existing methods of environmental assessment, by providing a sensitive, non-invasive, rapid multi-endpoint assessment of effects of anthropogenic chemicals on organism in vivo. Three invertebrate species, Mytilus edulis, Hyas araneus and Strongylocentrotus droebachiensis was exposed to natural and anthropogenic chemicals in …

International Standards For Detaining Terrorism Suspects: Moving Beyond The Armed Conflict-Criminal Divide, Monica Hakimi

Articles

Although sometimes described as war, the fight against transnational jihadi groups (referred to for shorthand as the "fight against terrorism") largely takes place away from any recognizable battlefield. Terrorism suspects are captured in houses, on street comers, and at border crossings around the globe. Khalid Shaikh Mohammed, the high-level Qaeda operative who planned the September 11 attacks, was captured by the Pakistani government in a residence in Pakistan. Abu Omar, a radical Muslim imam, was apparently abducted by U.S. and Italian agents off the streets of Milan. And Abu Baker Bashir, the spiritual leader of the Qaeda-affiliated group responsible for …

Low Power Energy Harvesting And Storage Techniques From Ambient Human Powered Energy Sources, Faruk Yildiz

Dissertations and Theses @ UNI

Conventional electrochemical batteries power most of the portable and wireless electronic devices that are operated by electric power. In the past few years, electrochemical batteries and energy storage devices have improved significantly. However, this progress has not been able to keep up with the development of microprocessors, memory storage, and sensors of electronic applications. Battery weight, lifespan and reliability often limit the abilities and the range of such applications of battery powered devices. These conventional devices were designed to be powered with batteries as required, but did not allow scavenging of ambient energy as a power source. In contrast, development …

Give ‘Em Hill: The Fighter Persona In Hillary Clinton’S 2008 Presidential Campaign, Rebecca Diane Buel

Dissertations and Theses @ UNI

Hillary Clinton announced her intentions to form a presidential exploratory committee on January 20, 2007. The campaign that followed this announcement was complicated by the many existing images created by Hillary Clinton's many years in the public eye. Throughout these many years, Hillary Clinton struggled to establish voter identification, and was frequently the subject of public criticism, rendering many existing images negative. Furthermore, she served in a variety of roles: governor's wife, first lady, senator, and most recently presidential candidate. Because of the conflicting data resulting from Hillary Clinton's negative publicity and her many roles, her presidential campaign faced a …

Insects Inhabiting The Burrows Of The Ozark Pocket Gopher In Arkansas, Peter W. Kovarik, Stephen W. Chordas Iii, H. Robison, P. Skelley, M. Connior, J. Fiene, G. Heidt

Journal of the Arkansas Academy of Science

Pocket gopher burrows provide a stable environment for a variety of inquilines; hence this mammal is regarded as a keystone species. Most of the arthropods inhabiting pocket gopher burrows are restricted to this microhabitat. As part of a planned state-wide biotic survey of insects inhabiting this unusual microhabitat, we have focused our initial sampling efforts on the Ozark pocket gopher (Geomys bursarius ozarkensis; Geomyidae). In 2004 and 2005, pitfall traps were established in pocket gopher burrows and in 2007 and 2008, nests and associated chambers were excavated. Retrieved samples contained scarab, histerid, and rove beetles, cave crickets and anthomyiid flies. …

A System For Automatically Annotating Traditional Irish Music Field Recordings, Bryan Duggan, Brendan O'Shea, Padraig Cunningham

Conference papers

This paper presents MATT2 (Machine Annotation of Traditional Tunes). MATT2 is a novel system which can automatically annotate field recordings of traditional Irish music with useful metadata such as tune name, key signature, time signature, composer and discography. MATT2 works by using a number of algorithms to automatically transcribe digital audio to be annotated to the ABC music notation language. It then compares these transcriptions against a corpus of 860 human made transcriptions in ABC using a variation of the edit distance algorithm. Results using MATT2 to annotate fifty recordings of flute and fiddle tunes demonstrate a high success rate …
