Flowering phenology of alpine plant communities along a gradient of snowmelt timing
Flowering phenology of alpine plant communities was observed at seven sites (two fellfields, two alpine meadows, and three snowbeds) in 1996 and 1997 in the Taisetsu Mts., northern Japan. These sites were selected along a gradient of snowmelt time. In total, flowering phenologies of 39 species were...

Flowering phenology of alpine plant communities was observed at seven sites (two fellfields, two alpine meadows, and three snowbeds) in 1996 and 1997 in the Taisetsu Mts., northern Japan.

The length of flowering season within communities decreased with lateness of snowmelt from 88 days at the fellfield site to 32 days at the snowbed site. The onset of flowering varied among species at the early snowmelt sites, and it became concentrated within narrow periods among species at the later snowmelt sites. Interspecific overlap of anthesis was large in the late flowering season at the earliest snowmelt site, whereas it was large in the early flowering season at the snowbed sites.
