Female reproductive parameters and population demographics of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(Springer Nature, 2017-11-20)This study investigates the female reproductive parameters and population demographics of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland, using long-term relational sightings and photographic ... -
Female reproductive parameters and population demographics of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(Springer, 2018-09)Abstract This study investigates the female reproductive parameters and population demographics of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland, using long-term relational sightings and ... -
Fine-scale sociality reveals female–male affiliations and absence of male alliances in bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(Society for Marine Mammalogy, 2019-04-29)Knowledge of social behavior at an individual level is central to our understanding of complex mammalian societies. In this study, we analyzed the fine-scale sociality of wild bottlenose dolphins in the Shannon Estuary, ... -
Fine-scale spatial association between baleen whales and forage fish in the Celtic Sea
(2015-09)Baleen whales can be regularly observed in the Celtic Sea; however, little is known about their local foraging behaviour. This study's objective was to determine whether or not baleen whales selectively prey upon particular ... -
A first acoustic density estimate for sperm whales in Irish offshore waters
(International Whaling Commission, 2020)Previous studies off western Ireland have suggested that substantial numbers of, mainly male, sperm whales may be found in these habitats. Whaling vessels operating from shore stations in Ireland in the early 20th century ... -
A flexible decision support tool for MSY-based MPA design
(2016)ICES WGEF recommends that demersal elasmobranchs be managed using spatial proxies 11 for Maximum Sustainable Yield. Here we combine escapement biomass – the percentage of the stock which must be retained each year to ... -
Global status of groundfish stocks
(John Wiley & Sons, Inc, 2021-05-04)We review the status of groundfish stocks using published scientific assessments for 349 individual stocks constituting 90% of global groundfish catch. Overall, average stock abundance is increasing and is currently above ... -
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 ... -
