| sources of organochlorine contaminants and mercury in seabirds from the aleutian archipelago of alaska: inferences from spatial and trophic variation. | persistent organochlorine compounds and mercury (hg) have been detected in numerous coastal organisms of the aleutian archipelago of alaska, yet sources of these contaminants are unclear. we collected glaucous-winged gulls, northern fulmars, and tufted puffins along a natural longitudinal gradient across the western and central aleutian islands (buldir, kiska, amchitka, adak), and an additional 8 seabird species representing different foraging and migratory guilds from buldir island to evaluate: ... | 2008 | 18692865 |
| fatty acid signatures of stomach oil and adipose tissue of northern fulmars (fulmarus glacialis) in alaska: implications for diet analysis of procellariiform birds. | procellariiforms are unique among seabirds in storing dietary lipids in both adipose tissue and stomach oil. thus, both lipid sources are potentially useful for trophic studies using fatty acid (fa) signatures. however, little is known about the relationship between fa signatures in stomach oil and adipose tissue of individuals or whether these signatures provide similar information about diet and physiology. we compared the fa composition of stomach oil and adipose tissue biopsies of individual ... | 2007 | 17712565 |
| preliminary assessment of avian stomach oils: a vector of contaminants to chicks and potential for diet analysis and biomonitoring. | bird species from the order procellariiformes or petrels, including the northern fulmar (fulmarus glacialis), produce high lipid and high energy content stomach oils from the prey they consume, which enables them to exploit distant marine food sources. stomach oils are also used as a food source for chicks and for defensive purposes. samples of stomach oils from two arctic colonies, st. george island alaska, usa and cape vera, devon island nunavut, canada, were collected and analyzed for organoc ... | 2010 | 20707316 |
| avian cholera causes marine bird mortality in the bering sea of alaska. | the first known avian cholera outbreak among wild birds in alaska occurred during november 2013. liver, intestinal, and splenic necrosis consistent with avian cholera was noted, and pasteurella multocida serotype 1 was isolated from liver and lung or spleen in crested auklets (aethia cristatella), thick-billed murres (uria lomvia), common eider (somateria mollissima), northern fulmars (fulmarus glacialis), and gulls (larus spp.). | 2015 | 26251989 |
