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 ...
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 ...
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 ...
A note on long-distance matches of bottlenose dolphins (tursiops truncatus) around the Irish coast using photo-identification
(International Whaling Commission, 2009-01)
Images of 120 individual bottlenose dolphins from around the Irish coast were obtained from three photo-identification catalogues. Twenty three individuals were subsequently re-sighted, which is a re-sighting rate of 19%. ...
