Abstract
Charnov and Schaffer''s (1973) model for annual vs. perrennial reproduction in plants is extended to incude both density dependence and environmental variability. Two models of density dependence were investigated; the method of invasibility analysis (Turelli 1978) was used to study their behavior. The results are interpreted in terms of bet-hedging theory; the criticisms of this interpretation by Hastings and Caswell (1979) are unfounded.
