 note = {P(論文), The population number of the Adelie penguin in the rookeries of the Syowa Station area, East Antarctica was counted as part of the biological monitoring program of JARE-24. The maximum number at each rookery in the 1983-84 breeding season was in the range of the assumed population size, but the number of penguins increasing for two years since 1981 began to decline steeply in the 1983-84 season. The annual fluctuation of penguin numbers in the Syowa Station area was discussed in relation to climatic and sea ice condition and possible human disturbances.},
