An AFLP analysis of genetic diversity within and between the ecotypes of the alpine sedge Carex curvula s.l.

Abstract

The alpine sedge Carex curvula is the dominant species of most European alpine tundra. II exhibits a calcifuge ecotype (C. curvula ssp. curvula)n d a calcicole ecotype (C. curvula ssp . rosae). Extensive data set on the geographical distribution , morpho-anatomy and ecology of these two ecotypes provides a unique framework for assessing the genetical basis of this ecotypic differentiation.
