| 英文摘要 | Background and aimsThe differences in multi-elemental concentrations among plant species provide insightful information for understanding species coexistence in forest ecosystems, known as the biogeochemical niche separation. As most of the studies focused on leaf elemental concentrations, it is unclear whether belowground fine roots exhibit biogeochemical niche separation and whether there are close linkages of elemental concentrations among leaves, fine roots and rhizosphere soils.MethodsNine element (N, P, K, Ca, Mg, Mn, Zn, Cu, and Fe) concentrations in leaves, fine roots and rhizosphere soils were measured for three tree species, three woody shrub species, and three herbaceous species in three subtropical plantations.ResultsElemental concentrations in leaves and fine roots were significantly different between woody and herbaceous species. Notably, the elemental concentrations differed more significantly for leaves than for fine roots, which indicated that leaves, as the most metabolically active tissues, tended to maintain their unique elemental concentrations within a particular functional type. Despite the different elemental needs between leaves and fine roots, most elemental concentrations of leaves were closely associated with those of the fine roots, highlighting the relationship between leaf and root ecological processes. Elemental concentrations in leaves or fine roots were not significantly correlated with those of the rhizospheres.ConclusionsThere is evidence for biogeochemical niche separation between coexisting woody and herbaceous species to avoid competition. Our results generalized the biogeochemical niche hypothesis to belowground tissues, which offered new insights into a better understanding of species evolution and coexistence in ecosystems. |
