| organochlorines in greenland glaucous gulls (larus hyperboreus) and icelandic gulls (larus glaucoides). | glaucous gulls (larus hyperboreus) and icelandic gulls (larus glaucoides) were sampled in 1994 from four different areas in greenland, three on the west coast and one on the east coast. livers of 93 glaucous gulls and seven icelandic gulls were analysed for polychlorinated biphenyls (pcbs, iupac nos. 28, 31, 52, 101, 105, 118, 138, 153, 156 and 180), ddts (p,p'-dde, p,p'-ddd, p,p'-ddt), hexachlorocyclohexanes (alpha-, beta- and gamma-hch), hexachlorobenzene (hcb) and trans-nonachlor (tnc). the o ... | 2000 | 10682360 |
| lead, cadmium, mercury and selenium in greenland marine biota and sediments during amap phase 1. | lead, cadmium, mercury and selenium levels in the greenland marine environment from the first phase of the amap are presented. samples were collected in 1994-1995 covering four widely separated regions in greenland. samples included sediments, soft tissue of blue mussel; and liver of polar cod, shorthorn sculpin, glaucous gull, iceland gull and ringed seal. concentrations of lead were found to increase with the size of blue mussel, but not with the age of gulls or ringed seal. both cadmium and m ... | 2000 | 10682352 |
| plastic and non-plastic debris ingestion in three gull species feeding in an urban landfill environment. | plastic debris is recognized as a widespread, common and problematic environmental pollutant. an important consequence of this pollution is the ingestion of plastic debris by wildlife. assessing the degree to which different species ingest plastics, and the potential effects of these plastics on their health are important research needs for understanding the impacts of plastic pollution. we examined debris (plastic and other types) ingestion in three sympatric overwintering gull species (herring ... | 2018 | 29282493 |
| seabird species vary in behavioural response to drone census. | unmanned aerial vehicles (uavs) provide an opportunity to rapidly census wildlife in remote areas while removing some of the hazards. however, wildlife may respond negatively to the uavs, thereby skewing counts. we surveyed four species of arctic cliff-nesting seabirds (glaucous gull larus hyperboreus, iceland gull larus glaucoides, common murre uria aalge and thick-billed murre uria lomvia) using a uav and compared censusing techniques to ground photography. an average of 8.5% of murres flew of ... | 2017 | 29263372 |
