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
(Galway-Mayo Institute of Technology, 2012)Despite repeated calls for an ecosystem-based approach to the management of marine resources, little information exists on the ecosystem role and requirements of top predators such as baleen whales in Irish waters. Considering ... -
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 ... -
Phytoplankton precision trials in the enumeration and identification of marine microalgae through the scheme “Biological Effects Quality Assurance in Monitoring Programmes (BEQUALM)”.
(Galway-Mayo Institute of Technology, 2010)Scientists are coming under increased pressure in recent years to show that results they obtain arising from their scientific work are quality assured and stand up to scrutiny by independent expert auditors. This has meant ... -
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 ... -
Population dynamics of 0-group flounder (Platichthys flesus L.) in Galway Bay, West of Ireland and the value of flounder from shore angling tourism in Ireland
(Galway-Mayo Institute of Technology, 2007)The economic value of flounder from shore angling around Ireland was assessed. Flounder catches from shore angling tournaments around Ireland were related to domestic and overseas shore angling expenditure in order to ... -
Population dynamics of O-group plaice, Pleuronectes platessa L., on sandy beach nursery grounds in Galway Bay, the West Coast of Ireland, 2002 to 2006.
(Galway-Mayo Institute of Technology, 2006)The recruitment of 0-group plaice to sandy beach nursery grounds in Galway Bay was examined, using a Riley push-net, from February to June in 2005 and 2006. Sampling was carried out every two weeks on spring tides. Three ... -
Population genetic structure of brown crab (Cancer pagurus) in Irish waters
(Galway-Mayo Institute of Technology, 2009)The brown crab (Cancer pagurus) fishery in Ireland is one of the most important financially and socio-economically, with the species worth approximately €15m per year in the first half of the decade. Only mackerel (Scomber ... -
Population structure and management of Albacore tuna (Thunnus alalunga) in the North Atlantic Ocean) in the North Atlantic Ocean
(Galway-Mayo Institute of Technology, 2017-12)Albacore tuna (Thunnus alalunga) is a globally important species found in the tropical and temperate zones of every ocean including the Mediterranean Sea. The aim of this research is to advance the current knowledge ... -
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. ... -
Synchronous reproduction may facilitate introgression in a hybrid mussel (Mytilus) population
(Galway-Mayo Institute of Technology, 2009)Mussel populations on the Irish Atlantic coast comprise an interbreeding mixture of the blue mussel, Mytilus edulis (L.) and the Mediterranean mussel, Mytilus galloprovincialis (Lmk.). The occurrence of hybrid genotypes ... -
