Document Summary
Does not identify the factors responsible for slowing growth. Logistic population growth has given rise to the concept of r-selected species: r-selected species: Small, low reproductive investment per offspring, highly fecund, early maturity, short-lived, type iii survivorship. Poor competitors, often dominant during early succession, pioneer species, well adapted to unstable environments. In a similar manner, logistic population growth also suggests the presence of k-selected species: k-selected species. Large, high reproductive investment per offspring, low fecundity, late maturity, long lived, type i survivorship. Superior competitors, often dominant during late succession, well adapted to stable environments. Intraspecific cooperation- as population grow, fitness increases because of increases in mates, feeding success, and defense. Intraspecific competition- as populations continue to grow, fitness declines because of decreasing per capita resources. Simultaneous demand for resources in limited supply: as populations continue to grow, interactions with other species also increase.
