Strong and lasting impacts of past global warming on baleen whales and their prey
(Wiley, 2022-02-02)Global warming is affecting the population dynamics and trophic interactions across a wide range of ecosystems and habitats. Translating these real-time effects into their long-term consequences remains a challenge. The ... -
Evidence of a range expansion in sunfish from 47 years of coastal sightings
(Springer Nature, 2022-01-13)Almost nothing is known about the historical abundance of the ocean sunfish. Yet as an ecologically and functionally important taxa, understanding changes in abundance may be a useful indicator of how our seas are responding ... -
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 ... -
Selecting appropriate plant indicator species for Result-Based Agri-Environment Payments schemes
(Elsevier Ltd, 2021-04-19)Agri-Environment Schemes (AES) have long been implemented across Europe to incentivise farmers to alter their management practices to improve biodiversity and water, air and soil quality. However, the cost-effectiveness ... -
Elemental composition of illicia and otoliths and their potential application to age validation in white anglerfish (Lophius piscatorius linnaeus, 1758)
(Elsevier Ltd, 2021-08-20)The incorporation of trace elements into the calcified structures of fish can vary seasonally. Interpretation of these seasonal signals can provide information about fish age. This approach offers great promise for objectively ... -
Selection on ancestral genetic variation fuels repeated ecotype formation in bottlenose dolphins
(American Association for the Advancement of Science, 2021-10-27)Studying repeated adaptation can provide insights into the mechanisms allowing species to adapt to novel environments. Here, we investigate repeated evolution driven by habitat specialization in the common bottlenose ... -
Speciation in the deep: genomics and morphology reveal a new species of beaked whale Mesoplodon eueu
(The Royal Society, 2021-10-27)The deep sea has been described as the last major ecological frontier, as much of its biodiversity is yet to be discovered and described. Beaked whales (ziphiids) are among the most visible inhabitants of the deep sea, ... -
Oceanographic Drivers of Cuvier's (Ziphius cavirostris) and Sowerby's (Mesoplodon bidens) Beaked Whales Acoustic Occurrence along the Irish Shelf Edge
(MDPI Journals, 2021-10-02)Cuvier’s and Sowerby’s beaked whales occur year-round in western Irish waters, yet remain some of the most poorly understood cetaceans in the area. Considering the importance of the area for anthropogenic activities and ... -
The conservation of the endangered Mediterranean common dolphin (Delphinus delphis): Current knowledge and research priorities
(Wiley, 2021-03-01)(1) Preservation of endangered species is now recognized as a relevant component of regional and global conservation actions achieved through the maintenance of the remaining populations in a favourable conservation status. ... -
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 ... -
Polluted porpoises: Generational transfer of organic contaminants in harbour porpoises from the southern North Sea
(Elsevier Ltd, 2021-07-09)Persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs), polybrominated diphenylethers (PBDEs) and hexachlorobenzene (HCB), bioaccumulate in marine ecosystems. Top predators contain high levels of ... -
Survival Rates and Capture Heterogeneity of Bottlenose Dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(Frontiers Media S.A., 2021-03-30)Adult survival is arguably the most important demographic parameter for long-lived species as it has a large impact on population growth, and it can be estimated for cetacean populations using natural markings and ... -
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. ... -
Polycyclic aromatic hydrocarbons (PAHs) in seabird eggs in Ireland
(Elsevier Ltd, 2021-06-19)Seabird eggs are considered a favourable matrix for monitoring marine pollutants and are widely used as higher trophic level indicators. Concentrations of Polycyclic aromatic hydrocarbons (Σ15PAH) were determined in the ... -
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), ... -
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 ... -
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 ... -
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 ... -
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 ... -
A first acoustic density estimate for sperm whales in Irish offshore waters
