Studies on the Ecological Geography of Subalpine Conifers : Distribution pattern of Abies mariesii in relation to the effect of climate in the postglacial warm period

Distribution pattern of subalpine conifers particularly of Abies mariesii and the effect of change of postglacial climate on it were studied, in order to interpret a well-known phenomenon, that the subalpine altitudes of mountains are entirely lacking coniferous forests in the regions of heavy snowfall on the Sea of Japan side of the central and northern Honshu, from the historical angle
