Gause competitive exclusion principle & Resource Partitioning
- Gause ‘s competitive exclusion principle states that the two closely related species competing for the same resources cannot coexist indefinitely and the competitively inferior one will be eliminated eventually.
- However, species facing competition might evolve mechanisms that promote coexistence rather than exclusion.
- One such mechanism is ‘resource partitioning’.
- In resource partitioning, if two species compete for the same resource, they could avoid competition by choosing, for instance, different times for feeding or different foraging patterns.
- MacArthur showed that five closely related species of warblers living on the same tree were able to avoid competition and co-exist due to behavioural differences in their foraging activities.
