Production and isolation of azaspiracid-1 and -2 from azadinium spinosum culture in pilot scale photobioreactors
(MDPI AG, 2012-06-13)Azaspiracid (AZA) poisoning has been reported following consumption of contaminated shellfish, and is of human health concern. Hence, it is important to have sustainable amounts of the causative toxins available for ... -
Quantitative analysis of azaspiracids in azadinium spinosum cultures
(Springer Nature, 2012-02-26)Azaspiracids (AZAs) are secondary metabolites of Azadinium spinosum that can accumulate in shellfish and cause food poisoning when consumed. We describe here an analytical procedure for the determination of AZAs in cultures ... -

Scavenging on trawled seabeds can modify trophic size structure of bottom-dwelling fish
(Oxford University Press (OUP), 2013-09-04)Disturbance by towed bottom-fishing gears often kills larger sensitive benthos, leading to changes in the abundance, size, and species composition of benthic communities. Short-term availability of trawl-damaged prey, and ... -
Self-starting cumulative sum harvest control rule (ss-cusum-hcr) for status-quo management of data-limited fisheries
(Canadian Science Publishing, 2016-03-01)We demonstrate a harvest control rule based on the self-starting cumulative sum (SS-CUSUM) control chart that can maintain a fish stock at its starting (status-quo) level. The SS-CUSUM is an indicator monitoring tool ... -
Size-selective fishing drives species composition in the celtic sea
(Oxford University Press (OUP), 2012-01-19)yFishing alters community size structure by selectively removing larger individual fish and by changing the relative abundance of different-sized species. To assess the relative importance of individual-and species-level ... -
Small-scale variation of ammonia oxidisers within intertidal sediments dominated by ammonia-oxidising bacteria nitrosomonas sp. amoa genes and transcripts
(Springer Nature, 2017-10-16)While numerous studies have investigated the abundance of ammonia oxidising bacteria and archaea (AOB/AOA) via the ammonia monooxygenase gene amoA, less is known about their small-scale variation and if amoA gene abundance ... -
Spatial heterogeneity in fishing creates de facto refugia for endangered celtic sea elasmobranchs
(Public Library of Science (PLoS), 2012-11-14)The life history characteristics of some elasmobranchs make them particularly vulnerable to fishing mortality; about a third of all species are listed by the IUCN as Threatened or Near Threatened. Marine Protected Areas ... -
Temporal trends in stock origin and abundance of juvenile herring (clupea harengus) in the irish sea
(Oxford University Press (OUP), 2009-05-22)Celtic Sea herring (Clupea harengus) larvae partly disperse into the Irish Sea, where they mix with the resident stock during their first year of life. This affects the reliability of the use of acoustic estimates of ... -

The role of sustained observations in tracking impacts of environmental change on marine biodiversity and ecosystems
(The Royal Society, 2014-08-25)Marine biodiversity currently faces unprecedented threats from multiple pressures arising from human activities. Global drivers such as climate change and ocean acidification interact with regional eutro-phication, ... -
Turning off the drip (‘data-rich, information-poor’) – rationalising monitoring with a focus on marine renewable energy developments and the benthos
(Elsevier BV, 2017-07-01)Marine renewable energy developments (MREDs) are rapidly expanding in size and number as society strives to maintain electricity generation whilst simultaneously reducing climate-change linked CO2 emissions. MREDs are part ...
