ResumoNumerous organisms inhabiting variable environments exhibit temporally dynamic reproductive strategies. Populations of such organisms demonstrate considerable variation in reproductive effort associated with environmental changes and thus shift between relative r- and K-positions on the r-K continuum. Failure to consider such dynamic strategies can result in misleading comparisons of populations and in incorrect interpretations of life-history strategies and corresponding selective pressures.
