Spatial separation of catches in highly mixed fisheries
(Springer Nature, 2018-09)
Mixed fisheries are the dominant type of fishery worldwide. Overexploitation in mixed fisheries occurs when catches continue for available quota species while low quota species are discarded. As EU fisheries management ...
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, ...
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, ...
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 ...
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 ...
Managing a Dynamic North Sea in the light of its ecological dynamics: Increasing occurrence of large baleen whales in the southern North Sea
(Elsevier Ltd, 2022-03-01)
A recent increase in sightings and strandings of humpback and to a lesser extent, fin whales in the southern North Sea has been well documented. This positive trend in the marine mammal community is to be welcome. A similar ...
Quantification of microplastic ingestion by the decapod crustacean Nephrops norvegicus from Irish waters
(Elsevier B.V., 2020-01-15)
Microplastics are widespread pollutants in the marine environment, yet few studies have assessed the abundance and characteristics of microplastics in commercial species. This study evaluates the presence of ingested ...
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 ...
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 ...
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 ...
