Toxaphene and other persistent organochlorine (OC) pesticides (chlordane-related compounds [sigmaCHL], DDT-related compounds [sigmaDDT], hexachlorocyclohexanes [sigmaHCH], tris(p-chloro-phenyl)methane, hexachlorobenzene, octachlorostyrene, dieldrin) were determined in fat of Laysan albatross (Diomedea immutabilis) and in fat and eggs of blackfooted albatross (Diomedea nigripes) from the central...

The keratin intermediate filament network is abundant in epithelial cells, but its function in the establishment and maintenance of cell polarity is unclear. Here, we show that Albatross complexes with Par3 to regulate formation of the apical junctional complex (AJC) and maintain lateral membrane identity. In nonpolarized epithelial cells, Albatross localizes with keratin filaments, whereas in ...

Prevalence of lead exposure and elevated tissue lead was determined in Laysan albatross (Diomedea immutabilis) in Hawaii. The relationship between lead exposure and proximity to buildings, between elevated blood lead and droopwing status, and elevated liver lead and presence of lead-containing paint chips in the proventriculus in albatross chicks was also examined. Finally, the effects of lead ...

Fisheries bycatch mortality poses a primary threat to the majority of world’s 22 albatross species, 15 which are at risk extinction. Although quantitative estimates often unavailable due relative or total absence monitoring, spatial overlap between fisheries and albatrosses is used estimate extent interaction, proxy for exposure bycatch, inform avoidance mitigation actions. Using comprehensive ...

Laysan albatross (Phoebastria immutabilis) ingest plastic marine debris of a wide range of shape, sizes and sources. To better characterize this plastic and provide insights regarding its provenance and persistence in the environment, we developed a simple method to classify plastic fragments of unknown origin according to the resin codes used by the Society of Plastics Industry. Known plastics...

Effective factors of tori-poles in reducing incidental catch of albatross were examined with the data from Japanese observer program in southern bluefin tuna fishery. A total of 727 observations were used in the analysis. The data in night settings were not used because observed numbers of albatross and other seabirds were not recorded correctly during night-setting. The tori-pole specification...

1. Albatross eggs and embryos were collected in field seasons from 1996 to 1998 by Department of Conservation field staff. Species collected were the Northern Royal albatross (Diomedea sanfordi), Northern Buller's mollymawk (Thalassarche (platei) (nova sp.)) and Chatham Islands mollymawk (Thalassarche eremita). 2. Tissues were submitted to ESR for chemical analysis. Chemicals of particular inte...

1. Industrial longline fishing has been suspected to impact upon black-footed albatross populations Phoebastria nigripes by increasing mortality, but no precise estimates of bycatch mortality are available to ascertain this statement. We present a general framework for quantifying the relationship between albatross population and longline fishing in absence of reliable estimates of bycatch rate...
