An abundance estimate for humpback whales Megaptera novaeangliae breeding around Boa Vista, Cape Verde Islands
(2014)The abundance of humpback whales occurring around Boa Vista, Cape Verde Islands, was estimated by mark-recapture modelling. Photographs of markings on tail flukes of individual whales were collected during the breeding ... -
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, ... -
Acoustic Monitoring of a Bottlenose Dolphin (Tursiops truncatus) Population: Trends in Presence and Foraging beyond the Limits of the Lower River Shannon SAC
(MDPI Journals, 2021-06-12)The Shannon dolphins are a population of bottlenose dolphins resident year round within the Lower River Shannon SAC, Ireland, which has been designated to protect this relatively small, genetically discrete population. ... -
Addressing cohort uncertainty through advanced length frequency and stage-based assessment models with application to anglerfish
(Atlantic Technological University, 2022-02)Fisheries stock assessments are important tools for successful management of fisheries. Reliability of a stock assessment model is often determined by the data available and accounting for key uncertainties in the data is ... -
Age, growth, and sexual dimorphism of the Southern Hemisphere long-finned pilot whale (Globicephala melas edwardii)
(Oxford University Press, 2022-02-03)Knowledge of population biological parameters can contribute to assessing the resilience of a population in the face of increasing anthropogenic pressures. Southern Hemisphere long-finned pilot whales (Globicephala melas ... -
Antimicrobial peptide gene expression in Atlantic salmon (Salmo salar) seven days post-challenge with Neoparamoeba perurans
(Elsevier Ltd, 2021-10-04)Amoebic gill disease in teleost fish is caused by the marine parasite Neoparamoeba perurans. To date, the role of antimicrobial peptides β-defensins and cathelicidins in this infection have not been explored. Using a ... -
Assessing stone walls habitat quality – Which factors affect bryophytes and macrolichens on farmland stone walls in Ireland?
(Elsevier B.V., 2022-05-11)Stone walls are ubiquitous field boundaries used to restrict livestock movement or to separate property. Bryophytes and lichens are often the dominant vegetation in dry stone walls and are strongly affected by local ... -
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 ... -
Assessment and monitoring of ocean noise in Irish waters
(Environmental Protection Agency, 2012)Anthropogenic noise is now recognised as a significant pollutant in the marine environment and there is a growing interest from the scientific community, policy makers and the general public in the effects of anthropogenic ... -
Assessment of impulsive and continuous low- frequency noise in Irish waters
(Springer-Verlag, 2016)As part of the European Union Marine Strategy Framework Directive (MSFD), member states are required to address noise pollution in the marine environment under Descriptor 11. This study aimed to provide a practical desk-based ... -
Biogeography in the deep: Hierarchical population genomic structure of two beaked whale species
(Elsevier B.V., 2022-10-14)The deep sea is the largest ecosystem on Earth, yet little is known about the processes driving patterns of genetic diversity in its inhabitants. Here, we investigated the macro- and microevolutionary processes shaping ... -
Biology and ecology of flatfish species on west of Ireland nursery grounds
(Galway-Mayo Institute of Technology, 2011)Commercial flatfish captured in demersal fisheries along the west coast of Ireland include quota species such as plaice (Pleuronectes platessa L), in addition to high value non-quota species, turbot (Psetta maxima L.) and ... -
Bottlenose dolphin (Tursiops truncatus) social structure in the Shannon Estuary, Ireland, is distinguished by age- and area-related associations
(Society for Marine Mammalogy, 2018-04)Social and network analyses that incorporate information on individuals within a population enhance our knowledge of complex species. In this study, the social structure of wild bottlenose dolphins in the Shannon Estuary, ... -

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 ... -
Cetaceans in Irish waters: a review of recent research
(2009)To date, 24 cetacean species have been recorded in Irish waters. These are protected by a range of legislation, including the Whale Fisheries Act, the Wildlife Act and the EU Habitats Directive, which oblige Ireland to ... -
Circles in the sea: annual courtship “torus” behaviour of basking sharks Cetorhinus maximus identified in the eastern North Atlantic Ocean
(John Wiley & Sons, Inc., 2022-08-05)Groups of basking sharks engaged in circling behaviour are rarely observed, and their function remains enigmatic in the absence of detailed observations. Here, underwater and aerial video recordings of multiple circling ... -
Combining genetic markers with stable isotopes in otoliths reveals complexity in the stock structure of Atlantic bluefin tuna (Thunnus thynnus)
(Springer Nature, 2020-09-07)Atlantic bluefin tuna (Thunnus thynnus) from the two main spawning populations in the Mediterranean and Gulf of Mexico occur together in the western, central and eastern Atlantic. Stock composition of catches from mixing ... -
Conservation management of common dolphins: Lessons learned from the North‐East Atlantic
(Wiley, 2019-11-19)(1) The short-beaked common dolphin is one of the most numerous cetacean species in the North-East Atlantic and plays a key functional role within the ecosystem as a top predator. However, in 2013, its conservation status ... -
The conservation of the endangered Mediterranean common dolphin (Delphinus delphis): Current knowledge and research priorities
