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. ... -
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 ... -
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 ... -
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 ... -
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 ... -
Taxonomy of the Lysianassoidea of the Northeast Atlantic and Mediterranean : an interactive identification key and studies on problematic groups
(Galway-Mayo Institute of Technology, 2006)A DELTA (DEscriptive Language for TAxonomy) database was constructed for 135 species of lysianassoid amphipods of the Northeast Atlantic and Mediterranean Sea, representing almost 20% of the total estimated number of ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Using archived otoliths to determine stock structure and early life history of plaice (Pleuronectes platessa L.)
(Galway-Mayo Institute of Technology, 2010)Plaice (Pleuronectes platessa) are an economically important flatfish in European waters. However, there remains much to be learned about the life history of this fish especially for the earliest stages. This chapter ... -
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, ... -
