Seed production of a masting dwarf shrub, Vaccinium myrtillus , in relation to previous reproduction and weather
In an analysis of a 50-year time series of seed production in bilberry (Vaccinium myrtillus L.) from Aust-Agder, southern Norway, both previous reproduction and weather contributed to explain annual berry production. There was a relatively regular fluctuation in bilberry production, with intervals b...
