On the Fresh-Water Microfauna of the Antarctic Region. II. Stabilityof Faunistic Composition of Antarctic Microorganisms
P(論文) The colonization of Antarctica by microorganisms has been analyzed during 1963-1966 by four ways of approach-faunological, sociological, biogeographical, and experimental-using material mainly from Langhovde, Syowa Station, McMurdo Sound, and the Ongul Islands. The first three of these overlap...

P(論文) The colonization of Antarctica by microorganisms has been analyzed during 1963-1966 by four ways of approach-faunological, sociological, biogeographical, and experimental-using material mainly from Langhovde, Syowa Station, McMurdo Sound, and the Ongul Islands. The first three of these overlap to some extent, and the experimental approach may also provide some clues to this problem.
