Document Summary
Contrasting life histories: r-selective strategies reproductive vs, k: occurs at karrying capacity less on reproduction, and more on out competing rival, r-k continuum, tendencies of r species" life histories, 1. Early maturation after birth and reproduce very early in their lives: 2. Don"t tend to live very long, type iii survivor curves produce many offspring early in life, but few survive reproduction: 3. High number of offspring per attempt: 5. If they do make it to reproductive age, the individuals that reproduce only do so once in lifetime: 6. Have no parental care hate their offspring: 7. The offspring are very small, with so many don"t have nutrients to sustain themselves, hence high mortality: 8. Non-competitive due to lack of resources/nutrients: 9. Few nutrients, lots of offspring means they will have small body size compared to more k-selected species: 10. R-selected strategy tend to occupy in unpredictable environments: 11.
