Investigation into the early life history of the European flounder (Platichthys flesus L.) with special emphasis in Galway Bay, Irish West Coast
(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 ...
An investigation into the effects of environmental variables on the early life history stages of fish, with special emphasis on the flatfish of the west of Ireland
(2012-10)
The temperate waters of the North-east Atlantic host a diverse marine ecosystem, and within that ecosystem fish are a valuable resource both in terms of ecosystem functioning and commercial exploitation. The West Coast of ...
Genetic variability and phylogeography of the invasive zebra mussel, dreissena polymorpha (PALLAS)
(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 ...
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 ...
Prey preferences of sympatric fin (Balaenoptera physalus) and humpback (Megaptera novaeangliae) whales revealed by stable isotope mixing models
(2013)
Over-exploitation of top predators and fish stocks has altered ecosystems towards less productive systems with fewer trophic levels. In the Celtic Sea (CS), discards and bycatch levels have prompted concern about some ...
Age, growth and reproductive biology of whiting Merlangius merlangus (Linnaeus 1758) in the Celtic Sea
(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 ...
Population dynamics, age, growth and maturity of lemon sole Microstomus kitt (Walbaum 1792) sampled between 2000-2002 off the west coast of Ireland
(Marine Institute, 2006)
The age, growth, maturity and population dynamics of lemon sale (Microstomus kin), from commercial catches off the west coast of Ireland (ICES division Vllb), was determined for the period November 2000 to February 2002. ...
Estimating fish stock population parameters from bottom trawl surveys: sources and magnitude of uncertainty
(2006)
Fisheries surveys are widely used in the stock assessment process by providing time series of relative abundance and recruitment strength. Surveys also provide biological data that have the potential to improve stock ...
Synchronous reproduction may facilitate introgression in a hybrid mussel (Mytilus) population
(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 ...
Distribution, seasonal occurrence, recruitment and growth of juvenile commercial flatfish species on the west coast of Ireland
(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 ...
