K selected species. Life Histories of K-selected and r-selected Species While reproductive strategies play a key role in life histories, they do not account for important factors like limited resources and competition. The regulation of population growth by these factors can be used to introduce a classical concept in population biology, that of K -selected versus r -selected species. The terms "r-selected" and "K-selected" come from a description of the population growth regimes of the two types of organisms.
