Levels of persistent organic pollutants in eastern north Atlantic humpback whales
(2013)
Blubber lipid concentrations of 14 organochlorine compounds and 10 polychlorinated biphenyls (PCB) were measured by gas chromatography with electron-capture detection in eastern North Atlantic humpback whales Megaptera ...
Density estimates of harbour porpoises phocoena phocoena at eight coastal sites in Ireland
(2014)
Single platform line-transect surveys with distance sampling were carried out at eight sites between July and September 2008 to derive density and abundance estimates of harbour porpoises. Over 37 days at sea, a total of ...
Insights into the trophic ecology of bottlenose dolphins (Tursiops truncatus) in Irish waters
(2015)
The stomach contents of 12 bottlenose dolphins were examined. Ten of the 11 samples originated from dolphins that stranded on the west coast of Ireland between 1999 and 2011, while the remaining dolphin was bycaught. Ten ...
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 ...
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 ...
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 ...
Prey preferences of sympatric fin (Balaenoptera physalus) and humpback (Megaptera novaeangliae) whales revealed by stable isotope mixing models
(2013)
Over-exploitation of top predators and fish stocks has altered ecosystems towards less productive systems with fewer trophic levels. In the Celtic Sea (CS), discards and bycatch levels have prompted concern about some ...
Short note: the first confirmed successful refloat of a stranded bottlenose dolphin (Tursiops truncatus) in Ireland and subsequent resighting with a neonate
(2014-05)
The article presents a study which discusses the refloating of bottlenose dolphins (Tursiops truncatus) and the subsequent resighting with a neonate in Ireland. Topics include the live-stranding events of a bottlenose ...
Accounting for the effects of lipids in stable isotope (δ13C and δ15N values) analysis of skin and blubber of balaenopterid whales.
(John Wiley & Sons, 2012)
RATIONALE: Stable isotope values (d13C and d15N) of darted skin and blubber biopsies can shed light on habitat use and diet of cetaceans, which are otherwise difficult to study. Non-dietary factors affect isotopic variability, ...
Breeding habitat of poorly studied humpback whales (Megaptera novaeangliae) in Boa Vista, Cape Verde
(2013)
The waters surrounding Cape Verde comprise one of two known breeding grounds for humpback whales in the North Atlantic. The population remains very small and has apparently failed to recover since the cessation of whaling ...
