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 ...
Bottlenose dolphin (Tursiops truncatus) social structure in the Shannon Estuary, Ireland, is distinguished by age- and area-related associations
(Society for Marine Mammalogy, 2018)
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, ...
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 ...
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, ...
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 ...
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 ...
