| Outline of Final Research Achievements |
To elucidate effects of global warming on tree communities in snowy mountains of northern Japan, effects snowmelt timing and spring frost on phenology and survival of Fagus crenata and Quercus crispla were investigated in Hakkoda mountains, Aomori prefecture. We found that the effective accumulative temperature for leaf expansion of Fagus crenata tends to increases as the frequency of spring frost increase and that timing of formation of vessels of Quercus crispla is delayed by low temperature due to snowpack in the late spring. Moreover, results of the investigation indicate that survival rate decreases as snowmelt delays for Fagus crenata seedlings and vise versa for Quercus crispla saplings.
