| avian bornaviruses in north american gulls. | avian bornaviruses, recently described members of the family bornaviridae, have been isolated from captive parrots and passerines as well as wild waterfowl in which they may cause lethal neurologic disease. we report detection of avian bornavirus rna in the brains of apparently healthy gulls. we tested 439 gull brain samples from 18 states, primarily in the northeastern us, using a reverse-transcriptase pcr assay with primers designed to detect a conserved region of the bornavirus m gene. nine b ... | 2015 | 25973630 |
| immunological and reproductive health assessment in herring gulls and black-crowned night herons in the hudson-raritan estuary. | previous studies have shown inexplicable declines in breeding waterbirds within western new york/new jersey harbor between 1996 and 2002 and elevated polychlorinated dibenzo-p-dioxins and polychlorinated biphenyls (pcbs) in double-crested cormorant (phalacrocorax auritus) eggs. the present study assessed associations between immune function, prefledgling survival, and selected organochlorine compounds and metals in herring gulls (larus argentatus) and black-crowned night herons (nycticorax nycti ... | 2013 | 23212976 |
| contaminant levels in herring (larus argentatus) and great black-backed gull (larus marinus) eggs from colonies in the new york harbor complex between 2012 and 2013. | birds living in coastal areas are exposed to severe storms and tidal flooding during the nesting season, but also to contaminants that move up the food chain from the water column and sediment to their prey items. we examine metals in herring gull (larus argentatus) and great black-backed gull (larus marinus) eggs collected from the new york/new jersey harbor estuary in 2012 and in 2013 to determine if there were significant yearly differences in metal levels. we test the null hypothesis that th ... | 2015 | 25471353 |
