Accounting for the effects of lipids in stable isotope (δ13C and δ15N values) analysis of skin and blubber of balaenopterid whales.
(John Wiley & Sons, 2012)
RATIONALE: Stable isotope values (d13C and d15N) of darted skin and blubber biopsies can shed light on habitat use and diet of cetaceans, which are otherwise difficult to study. Non-dietary factors affect isotopic variability, ...
Breeding habitat of poorly studied humpback whales (Megaptera novaeangliae) in Boa Vista, Cape Verde
(2013)
The waters surrounding Cape Verde comprise one of two known breeding grounds for humpback whales in the North Atlantic. The population remains very small and has apparently failed to recover since the cessation of whaling ...
Bivalve ligament - a new source of DNA for historical studies
(Aquatic Biology, 2007-12)
Bivalves are aquatic animals enclosed in 2 rigid shells that are held together by a hinge ligament. Features of the shell valves are important in taxonomy, and museums hold global collections of catalogued fossil, historical ...
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, ...
Impacts of the parasitic dinoflagellate Hematodinium sp. on Irish crustacean fisheries
(2010)
Infection of Cancer pagurus by a parasitic dinoflagellate of the genus Hematodinium is described for the first time in Ireland. An industry-based monitoring programme was established to determine seasonality of infection ...
Monitoring intertidal community change in a warming world
(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 ...
An investigation into the detection and identification of OsHV-1 μvar virus and associated risk factors causing mortalities in Crassostrea gigas in Ireland.
(2014)
Part two of this study investigated the detection of OsHV-1 μvar and associated risk factors during mortality outbreaks. An epidemiological study was conducted during 2011. 17 bays from around the Irish Coast were selected, ...
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
(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 ...
A longitudinal study of humpback whales in Irish waters
(Marine Biological Association of the United Kingdom, 2014)
Knowledge on the ecology of humpback whales in the eastern North Atlantic is lacking by comparison with most other ocean basins. Humpback whales were historically over-exploited in the region and are still found in low ...
