Discrete or not so discrete: Long distance movements by coastal bottlenose dolphins in UK and Irish waters
(2012)The potential for long distance movements in common bottlenose dolphins (Tursiops truncatus) from six UK and Irish study sites was examined using photographs of natural markings. Here we provide the first evidence for ... -
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 ... -
Drones can reliably, accurately and with high levels of precision, collect large volume water samples and physio-chemical data from lakes
(Elsevier B.V., 2022-02-15)The rapid development and application of drone technology has included water sampling and collection of physiochemical data from lakes. Previous research has demonstrated the significant potential of drones to play a future ... -
Dynamic gill and mucus microbiomes during a gill disease episode in farmed Atlantic salmon
(2022-10-06)Amoebic gill disease (AGD) and complex gill disease (CGD) are recurrent gill disorders in Atlantic salmon, resulting in significant aquaculture losses. The role of gill microbiomes in gill disease development is unclear. ... -
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 ... -
An Ethogram for Bottlenose Dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(Minuteman Press, 2017)Ethograms, or categorized lists of behavioral descriptors, are fundamental research tools in the study of animal behavior and are essential to the overall understanding of the behavioral ecology of a species. With specific ... -
An Ethogram for Bottlenose Dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(2017)Ethograms, or categorized lists of behavioral descriptors, are fundamental research tools in the study of animal behavior and are essential to the overall understanding of the behavioral ecology of a species. With specific ... -
Evaluation of the skill of length-based indicators to identify stock status and trends
(Oxford University Press, 2022-03-26)In data-poor situations, length-based indicators (LBIs) and reference points based on life history parameters have been proposed to classify stocks according to conservation status and yield optimization. Given the variety ... -
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 ... -
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
