Biotic potential

  1. 1. Biotic potential is the maximum reproductive capacity of a population under optimum environmental conditions. Full expression of the biotic potential of an organism is restricted by environmental resistance, any condition that inhibits the increase in number of the population. It is generally only reached when environmental conditions are very favorable. A species reaching its biotic potential would exhibit exponential population growth and be said to have a high fertility, that is, how many offspring are produced per mother. Chapman relates to a "vital index": Vital Index = (number of births/number of deaths)*100 Biotic potential is the highest possible vital index of a species; therefore, when the species has its highest birthrate and lowest mortality rate. Components Components of biotic potential include reproductive potential/potential natality (the upper limit to biotic potential in the absence of mortality) and survival potential (Because reproductive potential does not account for the number of gametes surviving, survival potential is a necessary component of biotic potential; it is the reciprocal of mortality) (in the absence of mortality, biotic potential = reproductive potential). Chapman also identified two components: nutritive potential (the ability to acquire and use food for growth and energy) and protective potential (potential ability of the organism to protect itself against the dynamic forces of the environment to assure successful fertilization (mating) and permit care of young).
