Cetaceans in Irish waters: a review of recent research
(2009)To date, 24 cetacean species have been recorded in Irish waters. These are protected by a range of legislation, including the Whale Fisheries Act, the Wildlife Act and the EU Habitats Directive, which oblige Ireland to ... -
Mucus: aiding elasmobranch conservation through non-invasive genetic sampling
(Endangered Species Research, 2013-09)Large-scale genetic sampling by non-invasive methods is of vital importance for the conservation of vulnerable or elusive species. In the marine environment, non-invasive genetic sampling can provide a powerful alternative ... -
Modelling abundance hotspots for data-poor Irish sea rays
(Elsevier, 2015)Skates and rays represent one of the most vulnerable components of fish communities in temperate demersal fisheries such as the Irish Sea. They also tend to be data poor in comparison to commercially exploited teleost fish. ... -
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 ... -
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 ... -
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 ... -
An abundance estimate for humpback whales Megaptera novaeangliae breeding around Boa Vista, Cape Verde Islands
(2014)The abundance of humpback whales occurring around Boa Vista, Cape Verde Islands, was estimated by mark-recapture modelling. Photographs of markings on tail flukes of individual whales were collected during the breeding ... -
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 ... -
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 ... -
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%. ... -
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 ... -
Social structure within the bottlenose dolphin (Tursiops truncatus) population in the Shannon Estuary, Ireland
(2010)The Shannon Estuary is home to Ireland’s only known resident population of bottlenose dolphins (Tursiops truncatus) and is designated as a candidate Special Area of Conservation (cSAC) for this species. Proper conservation ... -
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 ... -
Temporal and spatial trends in stranding records of cetaceans on the Irish coast, 2002–2014
(Marine Biological Association of the United Kingdom, 2016)Using Irish strandings data collected between 2002 and 2014, seasonal and annual trends in the number of strandings for all strandings identified to species level (N ¼ 1480), and for the five most frequently reported ... -
PESI - a taxonomic backbone for Europe
(2015-09)Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations,however, presents a serious challenge for ... -
A longitudinal study of humpback whales in Irish waters
(Marine Biological Association of the United Kingdom, 2014)Knowledge on the ecology of humpback whales in the eastern North Atlantic is lacking by comparison with most other ocean basins. Humpback whales were historically over-exploited in the region and are still found in low ... -
PCB pollution continues to impact populations of orcas and other dolphins in European waters
(Macmillan Publishers, 2016-01)Organochlorine (OC) pesticides and the more persistent polychlorinated biphenyls (PCBs) have well-established dose-dependent toxicities to birds, fish and mammals in experimental studies, but the actual impact of OC ... -
An experimental evaluation of the device/arterial wall compliance mismatch for four stent-graft devices and a Multi-layer Flow Modulator (MFM) device for the treatment of abdominal aortic aneurysms
(Elsevier Ltd., 2015)Purpose: To experimentally investigate the arterial wall/device compliance mismatch of four stent-graft devices and a multi-layer flow modulator within the supra- and infra-renal locations for the treatment of Abdominal ...
