Spatial genetic structure and clonal diversity in an alpine population of Salix herbacea (Salicaceae).

abstract：BACKGROUND AND AIMS:The co-occurring of evergreen and deciduous angiosperm trees in Asian tropical dry forests on karst substrates suggests the existence of different water-use strategies among species. In this study it is hypothesized that the co-occurring evergreen and deciduous trees differ in stem hydraulic traits ...
