Abstract

Local ecotypes were generally favoured in comparisons of survival, growth, and seed production. Path-coefficient analysis was used to estimate coefficients of a model of causal relations among fitness components (age-specific sizes and seed production) and to examine how differences in growth between ecotypes over a succession of phases lead to selection against introduced ecotypes at the level of seed production. Analysis revealed large differences between ecotypes in performance over many intervals and in many relations between fitness components, but differences did not occur at all growth stages, and introduced ecotypes were superior in several comparisons. -from Author
