What is r-selected species and K-selected species?

Webb5 sep. 2024 · K-selected species are characterized by long gestation periods lasting several months, slow maturation (and thus extended parental care), and long life spans. In addition, they tend to inhabit relatively stable biological communities, such as late-successional or climax forests (see ecological succession). WebbThe concepts of r and K selection and b and d selection are discussed and compared. The former pair of concepts will play a central role in the development of new theories … WebbThe theory of r- and K-selection was one of the first predictive models for life-history evolution. It helped to galvanize the empirical field of comparative life-history and dominated thinking on the subject from the late 1960s through the 1970s. Large quan- tities of field data were collected that claimed to test predictions of the theory. inclusive health clinic west end
