Allogenic succession

In ecology, allogenic succession is succession driven by the abiotic components of an ecosystem.[1] In contrast, autogenic succession is driven by the biotic components of the ecosystem.[1] An allogenic succession can be brought about in a number of ways which can include:

  • Volcanic eruptions
  • Meteor or comet strike
  • Flooding
  • Drought
  • Earthquakes
  • Non-anthropogenic climate change[2]
Not to be confused with Allotransplantation.

Allogenic succession can happen on a time scale that is proportionate with the disturbance. For example, allogenic succession that is the result of non-anthropogenic climate change can happen over thousands of years. [3]
