The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require 2015-08-04 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.

K-selected species have a population that is limited by carrying capacity (K), density dependent, and relatively stable. The organisms in their population are larger and longer lived, have a relatively later reproductive age, produce fewer offspring, and provide greater care for their offspring. The human species is K-strategist; that is, each mating pair has a small number of offspring, of which the majority will survive to adulthood and reach reproductive age. r-strategist species, such as some insects and most plants, have very large numbers of offspring, the majority of which will die before reaching physical maturity. Organisms whose life history is subject to r-selection are often referred to as r-strategists or r-selected. Organisms that exhibit r-selected traits can range from bacteria and diatoms, to insects and grasses, to various semelparous cephalopods and small mammals, particularly rodents. As with K-selection, below, the r/K paradigm (Differential K theory) has controversially been associated with human behavior and separately evolved populations.

r And K Reproductive Strategies r and K reproductive strategies define an animal as having either a tendency to produce large amounts of offspring which have limited parental care and less chance of survival (r strategy) or few offspring, which the parents invest considerable time and energy into (K Examples of r strategist species keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website 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. Notice that the vertical axis of the survivorship plots is on a log scale and that horizontal axis is scaled to the maximum lifetime for each species. r-strategists are species that can grow and reproduce fast to increase their population. k-strategists are species that grow and reproduce more slower than the r-strategists do.
