Resource partitioning
A subdivision of resources (such as space, food, nesting sites, etc.) that minimizes competition between similar species. Species with similar resource needs can evolve and change their behaviour to use a seperate set of resources. For example, seven Anolis lizards in tropical rainforest share common food needs - mainly insects. They avoid competition by occupying different sections of the rainforest. Some live on the leaf litter floor, others on shady branches, and thereby avoid competing over food in those sections of the forest. Similar to niche partitioning.
