Summary
Coexisting species divide resources by space, time or diet to reduce competition.
In depth
MacArthur's warblers fed in different parts of spruce trees. Anolis lizards divide perch height and diameter. Temporal partitioning includes day and night activity.
This explains the coexistence of similar species.
Partitioning can be along resource, space and time axes. It reduces competition and promotes coexistence, increasing diversity.
Example: five warbler species feed in different tree zones.
