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 ... -
Highly resolved spatiotemporal simulations for exploring mixed fishery dynamics
(Elsevier, 2020)To understand how data resolution impacts inference on mixed fisheries interactions we developed a highly resolved spatiotemporal discrete-event simulation model MixFishSim incorporating: i) delay-difference population ... -
Humpback Whales (Megaptera novaeangliae) in the Cape Verde Islands: Migratory Patterns, Resightings, and Abundance
(2020-01)Effective conservation of the endangered North Atlantic humpback whale (Megaptera novaeangliae) which breeds in the eastern North Atlantic around the Cape Verde Islands off West Africa requires information about their ... -
Impacts of large and small barriers on fish assemblage composition assessed using environmental DNA metabarcoding
(Elsevier B.V., 2021-05-24)River fragmentation caused by instream barriers is a leading cause of biodiversity loss, particularly for freshwater migratory fish, the vertebrate group that has suffered the steepest decline. However, most studies have ... -
Including unsexed individuals in sex-specific growth models
(Canadian Journal of Fisheries and Aquatic Sciences, 2017-04-19)Sexually dimorphic growth models are typically estimated by fitting growth curves to individuals of known sex. Yet, macrospically ascribing sex can be difficult, particularly for immature animals. As a result, sex-specific ... -
Insights into the trophic ecology of bottlenose dolphins (Tursiops truncatus) in Irish waters
(2015)The stomach contents of 12 bottlenose dolphins were examined. Ten of the 11 samples originated from dolphins that stranded on the west coast of Ireland between 1999 and 2011, while the remaining dolphin was bycaught. Ten ... -
An investigation into the effects of climate change on baleen whale distribution in the British Isles
(Elsevier B.V., 30-12-20)Climate change is predicted to impact the distribution of many marine species. In the North-East Atlantic and elsewhere in the world, studies indicate that climate change is leading to poleward shifts in cetacean distribution. ... -
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. ... -
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 ... -
Investigation of the transcriptomic response in Atlantic salmon (Salmo salar) gill exposed to Paramoeba perurans during early onset of disease
(Springer Nature, 2021-10-19)Amoebic Gill Disease (AGD), caused by the protozoan extracellular parasite Paramoeba perurans (P. perurans) is a disease affecting Atlantic salmon (Salmo salar). This study investigated the gill transcriptomic profile of ... -
Investigation of the first recent crayfish plague outbreak in Ireland and its subsequent spread in the Bruskey River and surrounding areas
(EDP Sciences, 2022-06-02)White-clawed crayfish (Austropotamobius pallipes) is a keystone species found in western European freshwater bodies, where it has suffered drastic declines due to pathogens, competition with nonindigenous crayfish species ... -
A landscape classification map of Ireland and its potential use in national land use monitoring
(Elsevier B.V., 2021-04-17)This study presents a novel landscape classification map of the Republic of Ireland and is the first to identify broad landscape classes by incorporating physiographic and land cover data. The landscape classification ... -
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), ... -
Levels of persistent organic pollutants in eastern north Atlantic humpback whales
(2013)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 ... -
Long-term trends in herring growth primarily linked to temperature by gradient boosting regression trees
(Elsevier B.V., 2020-09-01)Environmental change and fishing activity can produce directional trends in exploited fish populations with consequences for stock productivity. For herring in the Celtic Sea, size at age has been in steady decline since ... -
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 ... -
Low levels of microplastics recorded from the common periwinkle, Littorina littorea on the west coast of Ireland
(2019-12)Microplastics (MPs) are an environmental pollutant of increasing concern. However, little research has assessed MP levels in intertidal gastropods. The authors explored MP abundance in the gastropod Littorina littorea from ... -
Managing a Dynamic North Sea in the light of its ecological dynamics: Increasing occurrence of large baleen whales in the southern North Sea
(Elsevier Ltd, 2022-03-01)A recent increase in sightings and strandings of humpback and to a lesser extent, fin whales in the southern North Sea has been well documented. This positive trend in the marine mammal community is to be welcome. A similar ... -
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 ... -
Modelling abundance hotspots for data-poor Irish sea rays
(Elsevier, 2015)Skates and rays represent one of the most vulnerable components of fish communities in temperate demersal fisheries such as the Irish Sea. They also tend to be data poor in comparison to commercially exploited teleost fish. ...
