Population changes of Adelie and emperor penguins along the Prince Olav Coast and on the Riiser-Larsen Peninsula
Kato A, K Watanabe, Y Naito. 2004
The trends of penguin populations are thought to be reliable indicators of
ecosystem changes in the Southern Ocean. There are seven Ade Llie penguin colonies and
one emperor penguin colonyalong the Prince Olav Coast and one emperor penguin
colonyon the Riiser-Larsen Peninsula. We compiled and analyzed the available data
collected byairborne and ground census between 1971 and 2000 in order to determine
the breeding status of penguins in this area. Ade Llie penguin populations increased at
two colonies; no apparent trends were observed at other colonies. Emperor penguin
populations were high in the mid-1990s and suddenlydecreased in 2000. Populations
need to be carefullymonitored in the coming years.
