Crustaceans and biodiversity crisis
(1998)Talitrid amphipod crustaceans were recorded at about 240 sites around ireland using both published records and recent seashore surveys. Five species were present, the beachfleas Orchestia gammarellus and O. mediterranea, ... -
A phytochemical study of ilex and betula species
(Galway-Mayo Institute of Technology, 1999)A phytochemical study of the outer bark of native common holly (Ilex aquifolium), led to the isolation and identification of nine novel fatty acid esters of the pentacyclic triterpene a-amyrin. These compounds were the ... -
Determination of selenium in selenium enriched yeast.
(Galway-Mayo Institute of Technology, 1999)Selenium, although a rare mineral, is widely distributed in minute amounts in virtually all materials of the earth’s crust, its average abundance is approximately ~0.09ppm. Selenium is rarely found in its native state i.e. ... -
Speciation of chromium in a chromium enriched yeast.
(Galway-Mayo Institute of Technology, 2000)The sample under investigation in this project is an experimental chromium enriched yeast used as a possible additive in animal foodstuff, which was produced by growing yeast in the presence of chromium (III) chloride. ... -
Age, growth and population dynamics of lemon sole Microstomus kitt (Walbaum 1792) sampled off the West Coast of Ireland
(Galway-Mayo Institute of Technology, 2002)The age, growth, maturity and population dynamics of lemon sole (Microstomus kitt), captured off the west coast of Ireland (ICES division Vllb), were determined for the period November 2000 to February 2002. The maximum ... -
Age, growth and reproductive biology of whiting Merlangius merlangus (Linnaeus 1758) in the Celtic Sea
(Galway-Mayo Institute of Technology, 2003)Age, growth and reproductive biology were investigated for whiting (Merlangius merlangus) captured from the Celtic Sea (ICES division Vllg), for the period January 2001 to January 2002. Females dominated the sex ratio of ... -
Effect of Freeze-chill Technology and Modified Packaging on the Quality of Whiting (Merlangius merlcmgus), Mackerel (Scomber scombrus) and Salmon (Salmo salar) Portions
(Galway-Mayo Institute of Technology, 2003)Freeze-chilling involves freezing and frozen storage followed by thawing and chilled storage. It offers logistic benefits for fish packers as it enables packaged fillets to be held frozen and then released into the chill ... -
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 ... -
Diverse populations of T cells with NK cell receptors accumulate in the human intestine in health and in colorectal cancer
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2004)T cells expressing NK cell receptors (NKR) display rapid MHC-unrestricted cytotoxicity and potent cytokine secretion and are thought to play roles in immunity against tumors. We have quantified and characterized NKR+ T ... -
Distribution, seasonal occurrence, recruitment and growth of juvenile commercial flatfish species on the west coast of Ireland
(Galway-Mayo Institute of Technology, 2004)The population dynamics of juvenile flatfish were investigated on the west coast of Ireland. Firstly, beach seining was carried out to assess spatial and temporal variations in flatfish assemblages, on sandy beach nursery ... -
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 ... -
Age, growth, reproductive biology and population dynamics of the common megrim Lepidorhombus whiffiagottis (Walbaum, 1792) from off the west coast of Ireland
(Galway-Mayo Institute of Technology, 2004)A total of 4,964 common megrim Lepidorhombus whiffiagonis, were examined from commercial catches in Divisions VII b^, off the west coast of Ireland, between April 1997 and February 2001. A sex ratio of 31.8:1 females to ... -
Population Differentiation in Blue Whiting (Micromesistius poutassou) in the North East Atlantic Ocean
(Galway-Mayo Institute of Technology, 2005)Blue whiting is a commercially important gadoid fish found throughout the Atlantic Ocean and the Mediterranean. It is a pelagic, migratory species with feeding grounds in the Norwegian Sea and in the Bay of Biscay. The ... -
Extreme galaxies: TeV gamma-ray emission from the Blazar 1ES 2344+514
(Galway-Mayo Institute of Technology, 2005)This thesis describes an investigation of Very High Energy (VHE) gamma-ray emission from the blazar galaxy 1ES 2344+514, based on data from five observational seasons (1999-2004) using the Whipple 10-metre telescope in ... -
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 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 ... -
