What are r selected species?
Then, what are examples of R selected species?
Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy.
Additionally, what is a K selected species? K-selected species, also called K-strategist, species whose populations fluctuate at or near the carrying capacity (K) of the environment in which they reside.
Keeping this in consideration, what is r selected and K selected species?
The two evolutionary "strategies" are termed r-selection, for those species that produce many "cheap" offspring and live in unstable environments and K-selection for those species that produce few "expensive" offspring and live in stable environments.
What does R Selected mean?
r selection selection occurring when a population is far below the carrying capacity of an unstable environment: tends to favor individuals that reproduce early, quickly, and in large numbers so as to make use of ephemeral resources and ensure that at least some offspring survive.
