Phenology and resource allocation in a high arctic evergreen dwarf shrub, Cassiope tetragona
During the growing season of 1981, we studied phenological patterns of development of vegetative shoots and sexual organs, partitioning of biomass and productivity, and partitioning and concentrations of N, P, K, Ca, and Mg for the evergreen dwarf shrub Cassiope tetragona (Ericaceae) at a high arcti...
