Antarctic Birds

Gastrointestinal microflora of antarctic birds.

Most of the information on the gastrointestinal microflora of antarctic birds was obtained during the great decade of South-Polar exploration following the turn of the century. The report of Levin (1899) that bacteria could not be found in the intestines of arctic birds at Spitzbergen prompted similar studies by the naturalists and ship's physicians on the Antarctic expeditions. Ekel6f (1908) o...

Gastrointestinal bacteria of certain Antarctic birds and mammals.

An investigation was carried out of the aerobic gram-negative intestinal flora of 158 penguins, 30 skuas, and 66 seals from the Antarctic and sub-Antarctic zones and Phillip Island. Among penguins and seals, 17% and 11%, respectively, were devoid of aerobic enteric organisms, but microscopic examination showed the presence of other bacteria. The coliforms outnumbered the paracolons and nonlacto...

Antarctic birds breed later in response to climate change.

In the northern hemisphere, there is compelling evidence for climate-related advances of spring events, but no such long-term biological time series exist for the southern hemisphere. We have studied a unique data set of dates of first arrival and laying of first eggs over a 55-year period for the entire community of Antarctic seabirds in East Antarctica. The records over this long period show ...
