Implication

Randomly varying environments influence population growth, suggesting possible extinction despite expected increase.

Key Points

  • This research aims to analyze the impacts of environmental variability on population growth rates and extinction risks.
  • Analyzed population growth in context of random environmental fluctuations.
  • Examined statistical properties of logarithm of population size over time.
  • Identified correlation between growth rates and extinction probability.
  • Population size's logarithm follows a normal distribution over time.
  • Expected size may grow infinitely, but extinction risk can increase significantly.
  • Difference between geometric and arithmetic mean growth rates affects extinction likelihood.
