R-selected species reach sexual maturity early in life. They generally have a short life expectancy. Their population is not regulated by density. 2017-11-06 · These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care. R-selected species can include mosquitos, mice, and bacteria. In terms of the American bison as a k-selected species, the gestation period for bison is 9.5 months or roughly 285 days---only five days longer than the gestation period for humans.

2021-04-24 · Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O. Wilson; K-selected species—that is, species whose population sizes fluctuate at or near their carrying capacity (K)—make up the second strategy.

Whales, giraffes and elephants are examples of K-selected species. In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus on either an increased quantity of offspring at the expense of individual parental investment of r-strategists, or on a reduced quantity of offspring with a corresponding increased parental investment of K-strategists, varies widely, seemingly to promote success in particular environments. The concepts of quantity or quality offspr R-selected species live in variable, unstable habitats (environments with non-predictable conditions). R-selected species tend to be small in size and therefore requires a small habitat to live in. R-selected species reach sexual maturity early in life. They generally have a short life expectancy.
