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 initiated in a number of ways which can include:

Volcanic eruptions
Meteor or comet strike
Flooding
Drought
Earthquakes
Non-anthropogenic climate change^[2]

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]
