The life history of Ranunculus glacialis, an arctic‐alpine perennial herb, in Finnish Lapland
Dynamics and performance of established individuals of Ranunculus glacialis at the time of peak flowering were monitored in a mountain area in Finnish Lapland for five years (1982–1986). The plants reproduced only sexually, and their spatial distribution in 40 1‐m 2 quadrats was clumped. During the...

Dynamics and performance of established individuals of Ranunculus glacialis at the time of peak flowering were monitored in a mountain area in Finnish Lapland for five years (1982–1986).
