ABSTRACT
Plant reproductive ecology is largely concerned with the adaptive significance of the variation in traits associated with pollination, seed dispersal, and seedling establishment. Reproductive success in many flowering plants depends on ecological interactions with animal pollinators and seed dispersal agents. Plants exhibit diverse reproductive strategies involving a variety of different sexual systems as well as asexual reproduction. Traditional explanations for this diversity have focussed on the benefits of genetic variability and the harmful effects of inbreeding. Recent interest in ecological aspects of reproduction has led to a diversification of approaches, with models of sexual selection and optimal resource allocation currently receiving considerable attention.
