This means that r strategists are self-sufficient and their behavior rarely goes wrong. r Strategists: K Strategists: Climate: Variable or unpredictable: Relatively constant and predictable: Population size: Variable over time with wide fluctuations, usually below carrying capacity of environment: Relatively constant over time and often near carrying capacity of environment: Intraspecific and interspecific competition: Variable Here we provide evidence for r- and K-selection by comparing different species, as well as different genotypes within a species (all of the same basic life form). The concepts of r- and K-selection are not absolute, but are meaningful only by comparison. A given organism is more or less of an r-strategist only in comparison with another organism.

r & K strategies are the two evolutionary strategies under which many organisms & species are categorized. There is remarkable difference The r and K classification was originally proposed by the biologists Robert McArthur and E. O. Wilson (1967). The r selected species live in populations that are highly variable. The fittest individuals in these environments have many offspring and reproduce early. Examples: Oysters, Insects- … R and k strategies 1. Topic 2: Ecosystems 2.6 Changes 2.6.3 - 2.63: r and K strategiesTwo general types of life strategies can be identiﬁed for most organisms • r = growth rateEquilibrium or K strategy species (a species -not the individual - is at carrying capacity K)Opportunist or r strategy species (a species exists in the exponential phase of ofpopulation growth r) Thus the population of a K-strategist is near the carrying capacity K. Surviorship curves give us additional insight into r and K-selected strategies.

Species - Species - Speciation: Subspecies are groups at the first stage of speciation; individuals of different subspecies sometimes interbreed, but they produce many sterile male offspring. At the second stage are incipient species, or semispecies; individuals of these groups rarely interbreed, and all their male offspring are sterile. Examples of r-selected species include bacteria, insects, and fish. K strategists are very different in that they attempt to ensure the survival of their offspring by investing time in them, instead of investing in lots of them. It is a reproductive strategy that focuses on quality over quantity. K strategist …
