Investigation of multiwavelength correlations for the VHE gamma-ray blazar markarian 421 from 1995 to 2009
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 ...
The drivers and dynamics of fisher behaviour In Irish fisheries
It is widely acknowledged within the scientific community that a single species approach to European mixed fisheries can result in species-specific advice inconsistent with multi-species management objectives. Within the ...
Population Differentiation in Blue Whiting (Micromesistius poutassou) in the North East Atlantic Ocean
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 ...
Levels of persistent organic pollutants in eastern north Atlantic humpback whales
Blubber lipid concentrations of 14 organochlorine compounds and 10 polychlorinated biphenyls (PCB) were measured by gas chromatography with electron-capture detection in eastern North Atlantic humpback whales Megaptera ...
Management and evaluation of a range of forest species for use as cut foliage
This project explored the possibility of harvesting marketable foliage stems in addition to producing timber from plantations of Larix leptolepis, Cupressus macrocarpa ‘Goldcrest’ and Tsuga heterophylla. Data recorded ...
Marine fauna of county Wexford, Ireland: the fauna of rocky shores and sandy beaches
(The Marine Institute, 1998)
Information accumulated during 20 years of investigations on the coast of County Wexford is summarised. Topics include shore descriptions, faunal records, transectal surveys on rocky shores and sandy beaches, cryptofaunal ...
Defining habitat characteristics influencing the distribution, density and growth of Plaice (Pleuronectes Platessa) and Dab (Limanda Limanda) on west of Ireland nursery grounds
Plaice (Pleuronectes platessa, L.) and dab (Limanda limanda, L.) are among the most abundant flatfishes in the north-eastern Atlantic region and the dominant species in shallow coastal nursery grounds. With increasing ...
Evaluation of fish pots as a feasible fishing method in Irish waters, with specific reference to the physiological effects of common and alternate pots on the lesser spotted dogfish (Scyliorhinus canicula).
Finfish pots have emerged as a “responsible” gear, when used in combination with conservational and technical measures to sustain fisheries. Previous trials in Irish waters have offered no published reported data and so ...
Effects of selected post harvest processes on brown crab (Cancerpagurus L.) and European lobster (Homarus gammarus L.) from Irish Crustacean Fisheries
The crustacean fishery is important to the socio economics of rural and island communities around Ireland; with brown crab (Cancer pagurus) and European lobster (.Homarus gammarus) being the most valuable shellfish species. ...
Colonisation of artificially cleared Laminaria digitata (Huds.) Lamour. by the blue-rayed limpet Helcion pellucidum (L.) (Mollusca, Gastropoda)
The blue-rayed Helcion pellucidum is a herbivorous mollusc found on intertidal and sublittoral laminarian algae.
