Field enhancement of the parasitoid bracon hylobii (Hymenoptera: Braconidae) to control hylobius abietis (Coleoptera: Curculionidae); the large pine weevil
(Galway-Mayo Institute of Technology, 2012)Hylobius abietis (Coleoptera: Curculionidae), the large pine weevil is the most damaging pest of reforestation sites in Ireland. This study examined the possibility of manipulating populations of a species specific parasitoid, ... -
A framework for high availability and optimum system performance in an Application Service Provider (ASP) environment
(Galway-Mayo Institute of Technology, 2006-06)The Application Service Provision (ASP) model offers access to centrally managed and hosted applications, via the Internet, on a subscription / rental basis. From its inception in the late 1990s, many have heralded the ASP ... -
Genetic variability and phylogeography of the invasive zebra mussel, dreissena polymorpha (PALLAS)
(Galway-Mayo Institute of Technology, 2005)The zebra mussel, Dreissena polymorpha (Pallas), a bivalve species originally native to the Black and Caspian seas, has invaded Ireland in the last decade. Five microsatellite loci were used to investigate genetic diversity ... -
A holistic stock analysis of Albacore tuna (Thunnus alalunga) from the North Atlantic Ocean and Mediterranean Sea
(Galway-Mayo Institute of Technology, 2009)Albacore tuna (Thunnus alalunga, Bonnaterre, 1788) is a highly migratory scombrid with a cosmopolitan distribution inhabiting all the worlds’ ocean, in both tropical and temperate regions. Albacore juveniles and adults are ... -
Impacts of the parasitic dinoflagellate Hematodinium sp. on Irish crustacean fisheries
(Galway-Mayo Institute of Technology, 2010)Infection of Cancer pagurus by a parasitic dinoflagellate of the genus Hematodinium is described for the first time in Ireland. An industry-based monitoring programme was established to determine seasonality of infection ... -
The inshore distribution and abundance of small cetaceans on the West Coast of Ireland: site assessment for SAC designation and an evaluation of monitoring techniques
(Galway-Mayo Institute of Technology, 2009)To date, 24 cetacean species have been recorded in Irish waters. These are protected by a range of legislation, including the Whale Fisheries Act, the Wildlife Acts and the EU Habitats Directive, which oblige Ireland to ... -
Instrumentation and software for the VERITAS Project and the detection of TeV Gamma-Ray Emission from the BL Lacertae Object 1ES1959+650
(Galway-Mayo Institute of Technology, 2003)Transmission of Cherenkov light through the atmosphere is strongly influenced by the optical clarity of the atmosphere and the prevailing weather conditions. The performance of telescopes measuring this light is therefore ... -
An investigation into system security requirements and implementation in an Application Service Provider (ASP) environment
(Galway-Mayo Institute of Technology, 2006)Although the ASP model has been around for over a decade, it has not achieved the expected high level of market uptake. This research project examines the past and present state of ASP adoption and identifies security as ... -
An investigation into the detection and identification of OsHV-1 μvar virus and associated risk factors causing mortalities in Crassostrea gigas in Ireland.
(Galway-Mayo Institute of Technology, 2014)Part two of this study investigated the detection of OsHV-1 μvar and associated risk factors during mortality outbreaks. An epidemiological study was conducted during 2011. 17 bays from around the Irish Coast were selected, ... -
Investigation into the early life history of the European flounder (Platichthys flesus L.) with special emphasis in Galway Bay, Irish West Coast
(Galway-Mayo Institute of Technology, 2012)European flounder (Platichthys flesus L.) economic value is estimated to be worth over 68 million to the Irish economy (mainly from recreational angling activities). Despite such large species value, there is a considerable ... -
Investigation of multiwavelength correlations for the VHE gamma-ray blazar markarian 421 from 1995 to 2009
(Galway-Mayo Institute of Technology, 2011)The blazar Markarian 421 is an excellent laboratory for studying the physical processes within the jets of active galactic nuclei. In this thesis, a multiwavelength database has been compiled using data from the Whipple ... -
Investigation of the substrate specificity of glutamyl endopeptidase using casein substrates
(Galway-Mayo Institute of Technology, 2011)Electrophoretically and chromatographically pure P-casein was prepared from acid caseinate exploiting the differential solubility of different caseins in the presence of Ca2+ at 4°C and 30°C. The yield of P-casein was ... -
Ireland’s understudied flatfish: reproduction, age and growth of the dab Limanda limanda (L.) in Irish coastal waters
(Galway-Mayo Institute of Technology, 2012)In Ireland, although flatfish form a valuable fishery, little is known about the smallest, the dab Limanda limanda. In this study, a variety of parameters of reproductive development, including ovarian phase description, ... -

A molecular approach to the study of a mussel hybrid zone on the west coast of Ireland
(Galway-Mayo Institute of Technology, 2005)The shores of the northwestern Atlantic have two indigenous mussel species, the Blue mussel, Mytilus edulis and the Mediterranean mussel, Mytilus galloprovincialis. These two species once isolated by the last ice age, are ... -
Monitoring intertidal community change in a warming world
(Galway-Mayo Institute of Technology, 2004)If the earth’s climate is warming as predicted, the effects of this environmental change may begin to appear along a range of biological scales, including ecosystems, communities, populations and individual species. The ... -
Nutritional composition, quality and spoilage capacity of orange roughy (Hoplostethus atlanticus) from the North East Atlantic
(Galway-Mayo Institute of Technology, 2008)The nutritional composition o f orange roughy (collected from the Northeast Atlantic near the Rockall Trough) was studied on a seasonal basis. In addition samples were aged and stability assessed. Protein levels (16.68-16.21% ... -
On the ecology of rorqual whales (Balaenopteridae) in Irish waters using intrinsic markers
