Resource Partitioning a subdivision of resources and was developed to explain the evolution of animal species into a particular niche within an ecosystem. Today the term can be used to explain the behaviour of animals as well as their evolutionary development.

[edit] Resource partitioning in a ecosystem

Species with similar resource needs can evolve and change their behaviour to use a separate 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 while others live on shady branches, thereby avoiding competition over food in those sections of the forest. Similar to niche partitioning.

All resources are subject to partitioning, for example; space, food, nesting sites, that minimizes competition between similar species.
