Résumé : |
Seasonal patterns of seedling emergence and seed dispersal as well as their spatial patterns were measured for several dozen component species of a species-rich moist tall grassland community in warm temperate Japan. Although extremely high spatial heterogeneity of seedling emergence was observed for most of the species, which would have resulted from both the spatial heterogeneities of seed rain and "safe-site" distribution, the seasonal pattern of seedling emergence was less varied within a species over space and between years. Yearly seedling emergence in the community started when the accumulated daily air temperature (on a base temperature of 5 degree C) reached around 30 degree days (Kd) and the spring flush of emergence began when daily mean temperatures of warmer days rose abo[...] Seasonal patterns of seedling emergence and seed dispersal as well as their spatial patterns were measured for several dozen component species of a species-rich moist tall grassland community in warm temperate Japan.
