Some species will even inadvertently eat their own young if they are not immediately dispersed, but a few species, such as the cichlids, are K-selected and provide prolonged care and protection of the eggs and hatchlings. 2020-04-23 The two evolutionary "strategies" are termed r-selection, for those species that produce many "cheap" offspring and live in unstable environments and K-selection for those species that produce few "expensive" offspring and live in stable environments.

quality by something called the R versus K selection theory the R versus K selection Jun 1, 2002 The 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 The terms r and K came from variables in equations which described how populations would change over time. r represented the maximal reproductive rate of an R/K selection theory Template:DISPLAYTITLE:r/K selection theory In ecology, r/K selection theory relates to the selection of traits which promote success in.

r vs K theory is applied to whole species. r is characterized by sparse environment, fast maturity and large number of offsprings. K is characterized by dense environment, slow maturity and few offsprings. There are some species that falls in between, like sea turtles or trees. 2006-11-29 2016-05-30 2020-01-19 2016-04-25 Start studying R-selected vs K-selected.

R-selected are those that reproduce rapidly and produce a lot of progeny; bacteria are an example. K-selected are those that Terms in this set (15) K selected. Poor colonizers. R selected. Reach sexual maturity rapidly. K selected. Slow maturity.
