Samenvatting
(1) Life-history variation among four ecologically contrasting populations of Agrostis stolonifera was examined using a reciprocal-transplant technique in natural habitats.
(2) Survival, growth and flowering were mainly determined environmentally across transplant sites, although population effects in growth and flowering were present. Significant population-transplant-site interactions were also detected. Survival tended to be lower in summer than in winter, and alien populations tended to be more negatively influenced by the change of seasons than home populations.
(3) Phenotypic correlations between life-history determinants (survival, growth and flowering) tended to be positive, mainly due to their common environmental component.
(4) It is argued that the analyses of life histories, in particular for clonal organisms, should focus on the dynamics of separate ramets of known genotype.
