| the biogeochemical implications of massive gull flocks at landfills. | gulls have long been observed concentrating in flocks of tens to hundreds of thousands at the anthropogenic food sources provided by landfills. yet, the biogeochemical implications of the landfill gull phenomenon have been largely ignored. this study has two goals: 1) to understand the magnitude and geographic extent of landfill gulls in north america, and 2) to quantify the amount of carbon (c), nitrogen (n), and phosphorus (p) transported from landfills to gull roosting sites in order to under ... | 2017 | 28624727 |
| nitrite poisoning in herring gulls (larus argentatus) and ring-billed gulls (larus delawarensis). | landfill disposal of a fertilizer manufacturing waste product was associated with a die-off of gulls in new hanover county, north carolina. an estimated 250 herring and ring-billed gulls were found dead at the site following the initial disposal of this material. chemical analyses revealed that the fertilizer waste contained predominately calcium (12.0 to 22.2%) and nitrite (3.0 to 15.2%). contents of the proventriculi and gizzards of dead gulls also contained calcium (3.0 to 10.9%) and nitrite ... | 1986 | 3016349 |
