WebIt is argued that rand K-selection may have important ramifications for the understanding of life history evolution, but for the model to be useful, it must be interpreted strictly as it was originally formulated: as a model of density-dependent natural selection. Dawkins (36, p. 293) observes that "ecologists enjoy a curious love/hate relationship with the r/K … WebIn ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus on either an …
