Definition
|
|
Term
| They are populations of a roughly constant size whose members have low reproductive rates. The offspring produced require extensive postnatal care until they have sufficiently matured. They are very limited in resourses therefore they are a very competitive species. Humans are examples of a k-selected species. |
|
Definition
|
|
Term
| They are populations that experience rapid growth of the J-curve variety. The offspring produced are numerous, mature quite rapidly, and require very little postnatal care. Consequently, this population grows fast, reproduces quickly, and dies quickly. Bacteria are examples of r- selected species. |
