Document Summary
Try to relate them to fitness, know at least 4. Fitness: the genetic contribution by and individual"s descendants to future generations. Optimization approach: most often used, assume that observed combinations of life history traits are having as most as possible and dealing with it); conservative, diversified, adaptive coin flipping fitness is reproductive value. Natural selection favours those individuals that make the greatest proportionate contribution to the future of the population to which they belong. All life history component will affect this contribution, through their effect on fecundity and survival. Slow to fast continuum: life history traits often vary consistently with life form, habitat or environment conditions. Variation in one life history trait is often correlalted with variation o=in other life history traits. Asexual: formation of a new individual without fertilization. Slow life history: long time to sexual maturity, long life spans, low numbers of offspring, high parental investment. Fast life history: short time to sexual maturity .
