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 ...
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 ...
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 ...
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 ...
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 ...
An open-source database model and collections management system for fish scale and otolith archives
(Elsevier B.V., 2020)
Scales and otoliths (ear stones) from fish are routinely sampled for age estimation and fisheries management purposes. Growth records from scales and otoliths can be used to generate long-term time series data, and in ...
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 ...
Does Landscape Structure Affect the Presence of Woodland Specialist Pollinators in Farmland? Implications for Agri-Environment Scheme Design
(Royal Irish Academy, 2022-03-16)
Some pollinator species found in agricultural areas are strongly dependent on surrounding areas of natural or semi-natural habitats to nest and/or forage. Landscape structure has been shown to influence pollinator communities ...
Potential pathways, trophic transfer and bioindicators of microplastics in freshwater systems
(2018-03)
Microplastic (MP) polymers, 0.1 µm - 5 mm in size, are ubiquitous within aquatic environments. Due to their small size there is a risk that they may infiltrate and transfer within aquatic food webs. Though a limited number ...
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 ...
