In r/K selection theory, selective pressures are hypothesised to drive evolution in one of two generalized directions: r- or K-selection. These terms, r and K, are drawn from standard ecological algebra as illustrated in the simplified Verhulst model of population dynamics: where N is the population, r is the maximum growth rate, K is the carrying capacity of the local environment, and dN/dt, the derivative of N with respect to time t, is the rate of change in populati… WebThe theory is based on the idea that different species have different abilities to survive and reproduce in a given environment. K-selected species are those that have a high ability to survive and reproduce in a stable environment. They are typically large, slow-growing, and long-lived. r-selected species are those that have a low ability to ...
