Document Summary
Competition: use or defense of a limiting resource by one individual that reduced the availability of that resource to other individuals. Intraspeci c - between members of same species. Interspeci c - between members of different species. Modifying logistic equation to incorporate interspeci c competition. Competitive exclusion principle: two species that use a limiting resource in the same way cannot coexist inde nitely. Population must be more intense than interspeci c competition. Inter and intro petition can be determined from competition coef cients. Coexistence of species 1 and 2 is possible when: k1
