| trace metals, stable isotope ratios, and trophic relations in seabirds from the north pacific ocean. | trace elements including mercury, cadmium, selenium, and stable nitrogen isotope ratios (sigma15n) were measured in tissues of pacific seabirds. two species of albatross (diomedea immutabilis, diomedea nigripes), four species of shearwaters (puffinus bulleri, puffinus carneipes, puffinus griseus, puffinus tenuirostris), northern fulmar (fulmarus glacialis), and horned puffin (fratercula corniculata) were collected opportunistically by an experimental fishery in the north pacific ocean. two speci ... | 2005 | 16445091 |
| unexpected hydrogen isotope variation in oceanic pelagic seabirds. | hydrogen isotopes have significantly enhanced our understanding of the biogeography of migratory animals. the basis for this methodology lies in predictable, continental patterns of precipitation δd values that are often reflected in an organism's tissues. δd variation is not expected for oceanic pelagic organisms whose dietary hydrogen (water and organic hydrogen in prey) is transferred up the food web from an isotopically homogeneous water source. we report a 142‰ range in the δd values of fli ... | 2014 | 24989118 |
| chlorinated hydrocarbon contaminants and stable isotope ratios in pelagic seabirds from the north pacific ocean. | organochlorine pesticides, polychlorinated biphenyls (pcbs), and stable isotopes of nitrogen (delta15n) and carbon (delta13c) were determined in livers of eight seabird species (diomedea immutabilis, d. nigripes, fulmarus glacialis, puffinus bulleri, p. carneipes, p. griseus, p. tenuirostris, and fratercula corniculata) collected opportunistically from an experimental fishery in the north pacific ocean. concentrations of p, p'-dde were found in all samples but were highly variable among species, ... | 2005 | 15959703 |
