Variation in plant demographic trajectories: problems and opportunities

  1. 1. Variation in plant demographic trajectories:problems and opportunities Owen R. Jones & Roberto Salguero-Gómez jones@demogr.mpg.de salguero@demogr.mpg.deLaboratory for Evolutionary Demography,Max Planck Institute for Demographic Research,Rostock, Germany
  2. 2. Evolution is a demographic process “Evolution is driven by the propagation of genes, traits and individuals with and between populations. This propagation depends on the survival, fertility and dispersal at each age or stage during their life history.” Metcalf & Pavard (2007) TREE
  3. 3. Mortality/fertility rate Survivorship (lx)
  4. 4. Classical theories of the evolution of senescence Medawar (1952) Williams (1957) Hamilton (1966) Kirkwood (1977)Older ages are less important to evolutionthan younger ages:- force of selection declines with age.
  5. 5. Classical theories of the evolution of senescence ReproductionMortality Age Age “No life schedule ... could escape my spectrum of forces of senescence … in the farthest reaches of almost any bizarre universe” (Hamilton, 1966)
