Resource allocation in high-arctic vascular plants of differing growth form
Resource allocation strategies are described for a range of vascular plant species of a high-arctic lowland oasis, located adjacent to Alexandra Fjord, Ellesmere Island, N.W.T. The patterns of allocation of biomass and major nutrients (N, P, K, Ca, and Mg) differed greatly among the 16 species, whic...
