Allogenic succession
In ecology, allogenic succession is succession driven by the abiotic components of an ecosystem. In contrast, autogenic succession is driven by the biotic components of the ecosystem. An allogenic succession can be initiated in a number of ways which can include:
- Volcanic eruptions
- Meteor or comet strike
- Flooding
- Drought
- Earthquakes
- Non-anthropogenic climate change
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.
