Probable extirpation of a breeding colony of Short-tailed Albatross (Phoebastria albatrus) on Bermuda by Pleistocene sea-level rise.
Albatrosses (Diomedeidae) do not occur in the North Atlantic Ocean today except as vagrants, although five species were present in the early Pliocene. No fossil breeding sites of albatrosses were known previously. The timing of extinction of albatrosses in the North Atlantic was likewise unknown. Deposits that formed near present-day sea level along the southeastern shore of Bermuda contain rem...
متن کاملNutritional Autopsy of a Short-tailed Albatross (Diomedea albatrus) Weakened by Fishhook, Washed Ashore in Central Honshu, Japan
mouth of Fuji River, Shizuoka Prefecture, central Honshu and was brought to the nearby Shizuoka Municipal Nihondaira Zoo the same day. The bird died on 30 March, after being kept for 12 days at the Zoo. The bird was fed an average daily amount 622g of fish: mainly horse mackerel (Trachurus japonicus), some squid (Todarodes pacificus) and krill (Euphausia superba), but most of the food was regur...
متن کاملGastrointestinal Parasites in the Waved Albatross (Phoebastria irrorata) of Galápagos.
Using a fecal flotation technique, we detected three genera of endoparasites in the critically endangered Waved Albatross (Phoebastria irrorata) of Galápagos. These genera were Contracaecum, Tetrabothrius, and Cardiocephaloides. Juvenile albatrosses were more likely to be infected than adults, but we found no effect of sex or mass on infection probability.
متن کاملWind, Waves, and Wing Loading: Morphological Specialization May Limit Range Expansion of Endangered Albatrosses
Among the varied adaptations for avian flight, the morphological traits allowing large-bodied albatrosses to capitalize on wind and wave energy for efficient long-distance flight are unparalleled. Consequently, the biogeographic distribution of most albatrosses is limited to the windiest oceanic regions on earth; however, exceptions exist. Species breeding in the North and Central Pacific Ocean...
متن کاملContaminant-associated alteration of immune function in black-footed albatross (Phoebastria nigripes), a North Pacific predator.
Environmental pollution is ubiquitous and can pose a significant threat to wild populations through declines in fitness and population numbers. To elucidate the impact of marine pollution on a pelagic species, we assessed whether toxic contaminants accumulated in black-footed albatross (Phoebastria nigripes), a wide-ranging North Pacific predator, are correlated with altered physiological funct...
