| comparing an estimate of seabirds at risk to a mortality estimate from the november 2004 terra nova fpso oil spill. | on 21 november 2004, about 1000 barrels of crude oil were accidentally released from the terra nova fpso (floating production, storage and offloading) onto the grand banks, approximately 340 km east-southeast of st. john's, newfoundland. we estimated the number of vulnerable seabirds (murres (uria spp.) and dovekies (alle alle)) at risk from this incident by multiplying observed densities of seabirds with the total area covered by the slick, estimated at 793 km(2). a mean density of 3.46 murres/ ... | 2007 | 17328926 |
| biologging, remotely-sensed oceanography and the continuous plankton recorder reveal the environmental determinants of a seabird wintering hotspot. | marine environments are greatly affected by climate change, and understanding how this perturbation affects marine vertebrates is a major issue. in this context, it is essential to identify the environmental drivers of animal distribution. here, we focused on the little auk (alle alle), one of the world's most numerous seabirds and a major component in arctic food webs. using a multidisciplinary approach, we show how little auks adopt specific migratory strategies and balance environmental const ... | 2012 | 22815967 |
| a study of wrecked dovekies (alle alle) in the western north atlantic highlights the importance of using standardized methods to quantify plastic ingestion. | quantification of plastic ingestion across a range of seabirds is required to assess the prevalence of plastics in marine food webs. we quantified plastic ingestion in beached dovekies (alle alle), following a wreck in newfoundland, canada. of 171 birds, 30.4% had ingested plastic (mean 0.81±0.30 se pieces per bird, mass 0.005±0.002 se g per bird). most plastics were fragments of polyethylene and polypropylene. surprisingly, 37% were burned or melted, indicating a previously unreported source of ... | 2016 | 27609235 |
