Legacy and emerging contaminants in common guillemot Uria aalge eggs in Ireland and Wales
(Elsevier Ltd, 2021-06-12)
Guillemot eggs from multiple Irish colonies and one Welsh colony were analysed for legacy pollutants such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and other organochlorine compounds (OCs), ...
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 ...
Persistent pollutants in fresh and abandoned eggs of Common Tern (Sterna hirundo) and Arctic Tern (Sterna paradisaea) in Ireland
(Elsevier Ltd, 2-05-03)
Higher levels of persistent pollutants (Σ16PCB, Σ6PBDE, ΣHCH, ΣDDT, ΣCHL) were detected in fresh eggs of Common Terns Sterna hirundo from Rockabill Island near Dublin (Ireland's industrialised capital city) compared to ...
Modelling the transfer and accumulation of microplastics in a riverine freshwater food web
(Elsevier Ltd, 2022-02-26)
Microplastics are a pervasive pollutant of aquatic ecosystems and are reported to interact with a wide range of aquatic biota. The complexities of natural food webs means that the transfer and accumulation of microplastics ...
Assessing the Potential of Drones to Take Water Samples and Physicochemical Data from Open Lakes
(Environmental Protection Agency, 2020-09)
Water sampling remains a pivotal method for monitoring and understanding the condition of aquatic environments properly and effectively. Large-scale ecological water sampling and monitoring programmes require considerable ...
Investigation into the potential use of dietary supplementation to reduce the impact of Amoebic Gill Disease
(Elsevier Ltd, 2022-02-03)
Amoebic Gill Disease (AGD) is a disease affecting cultured Atlantic salmon (Salmo salar) which is caused by Paramoeba perurans. The immunomodulatory impact of functional foods has previously been demonstrated in salmon. ...
Microplastics in brown trout (Salmo trutta Linnaeus, 1758) from an Irish riverine system
(Elsevier B.V., 2020-09-01)
Rivers play an important role in the overall transport of microplastic pollution (1 μm to 5 mm), with fluvial dynamics expected to influence biotic interactions, particularly for fish. So far, there have been few assessments ...
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 ...
Investigation of the Initial Host Response of Naïve Atlantic Salmon (Salmo salar) Inoculated with Paramoeba perurans
(MDPI, 2021-04-02)
Amoebic Gill Disease (AGD), caused by the ectoparasite Paramoeba perurans is characterised by hyperplasia of the gill epithelium and lamellar fusion. In this study, the initial host response of naïve Atlantic salmon (Salmo ...
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, ...
