Density estimates of harbour porpoises phocoena phocoena at eight coastal sites in Ireland
(2014)
Single platform line-transect surveys with distance sampling were carried out at eight sites between July and September 2008 to derive density and abundance estimates of harbour porpoises. Over 37 days at sea, a total of ...
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 ...
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 ...
Discrete or not so discrete: Long distance movements by coastal bottlenose dolphins in UK and Irish waters
(2012)
The potential for long distance movements in common bottlenose dolphins (Tursiops truncatus) from six UK and Irish study sites was examined using photographs of natural markings. Here we provide the first evidence for ...
High concentrations of persistent organic pollutants in adult killer whales (Orcinus orca) and a foetus stranded in Ireland
(Elsevier Ltd., 2019-10-29)
Bio-accumulation of persistent organic pollutants including polychlorinatedbiphenyls (PCBs), brominated flame retardants and organochlorine pesticides continue to be of major concern for marine apex predators such as killer ...
The use of deep water berths and the effect of noise on bottlenose dolphins in the Shannon Estuary cSAC
(2016)
The Shannon Estuary on the west coast of Ireland is one of Europe’s premier deepwater berths catering for ships up to 200,000 deadweight tonnage. It is also Ireland’s only designated candidate special area of conservation ...
Assessment and monitoring of ocean noise in Irish waters
(Environmental Protection Agency, 2013)
This desk study was aimed to help Ireland meet the requirements of the Marine Strategy Framework Directive (MSFD) (2008/56/EC) under Descriptor 11: The introduction of energy, including underwater noise, is at levels that ...
Potential pathways, trophic transfer and bioindicators of microplastics in freshwater systems
(2018-03)
Microplastic (MP) polymers, 0.1 µm - 5 mm in size, are ubiquitous within aquatic environments. Due to their small size there is a risk that they may infiltrate and transfer within aquatic food webs. Though a limited number ...
