Persistent pollutants in fresh and abandoned eggs of Common Tern (Sterna hirundo) and Arctic Tern (Sterna paradisaea) in Ireland
(Elsevier Ltd, 2-05-03)Higher levels of persistent pollutants (Σ16PCB, Σ6PBDE, ΣHCH, ΣDDT, ΣCHL) were detected in fresh eggs of Common Terns Sterna hirundo from Rockabill Island near Dublin (Ireland's industrialised capital city) compared to ... -
An investigation into the effects of climate change on baleen whale distribution in the British Isles
(Elsevier B.V., 30-12-20)Climate change is predicted to impact the distribution of many marine species. In the North-East Atlantic and elsewhere in the world, studies indicate that climate change is leading to poleward shifts in cetacean distribution. ... -
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%. ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
PHOTO-IDENTIFICATION OF BOTTLENOSE DOLPHINS (TURSIOPS TRUNCATUS) IN TRALEE BAY AND BRANDON BAY, CO. KERRY: A CASE FOR SAC BOUNDARY EXTENSION
(ROYAL IRISH ACADEMY, 2016)The Lower River Shannon is a Special Area of Conservation (SAC) with bottlenose dolphins (Tursiops truncatus) as a qualifying interest, and is one of only two SACs for this species in Ireland. Bottlenose dolphins in the ... -
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 ...
