WebThe terms r-selection and K-selection are used by ecologists to describe the growth and reproduction strategies of organisms r-selected species have a high growth rate but low … WebSummary. This paper catalogues several different dichotomies that have all been termed r- and K-selection. The status of the concept of r- and K-selection is discussed and a more restricted usage of the terms is recommended. Download to read the full article text.
On r- and k-selection
Did you know?
WebK selection, or K-selection, is a reproduction process strategy that occurs when a population is at or near the point where the environment can provide for them. K selection favors few but highly efficient births. In ecology, K stands for carrying capacity, which is the environment’s ability to provide for a particular species.

WebThe terms r and K refer, respectively, to the maximum specific rate of increase (maximum specific growth rate minus minimum specific death rate) of an organism and to the density of individuals that a given environment can support at the population equilibrium.
WebApr 5, 2024 · K-selection, or "density-dependent selection", is a type of natural selection in which an organism's ability to survive and reproduce depends on its ability to compete for resources with other members of its species. K-selected species typically have long lifespans, invest heavily in offspring, and tend to produce fewer offspring. http://ib.bioninja.com.au/options/option-c-ecology-and-conser/c5-population-ecology/r--k-strategies.html
