摘要：

The reproductive mode and population structure of Tetraphis pellucida vary with shoot density. Low-density colonies reproduce asexually by gemmae and have a female-biased sex ratio. Increased density is correlated with increased sexual reproduction (sporophyte production). High levels of sporophyte production are accompanied by an increase in the proportion of males and by the onset of senescene. Plasticity of reproductive allocation can increase the fitness of T. pellucida in an unstable environment.
