r & K strategies are the two evolutionary strategies under which many organisms & species are categorized. There is remarkable difference Examples of r-selected species are many weeds such a dandelions, insects such as house flies and cockroaches, mice, passenger pigeons, and most bacteria. r-selected species tend to be small in size, have large broods with high fatalities , and live in unpredictable environments where the probability of long term survival is minimal. An r-strategist is an organism which falls under the type III survivorship style. (Just as a note: R-strategists, in theory, are supposed to be the opposite of k-strategists.

What does r-strategists or K-strategists mean ? for example, but are better adapted in terms of competition with other species in the conditions they may switch to K-strategist.
The lowercase r is used to represent growth rate in ecological equations, and so is also used to represent species with a high reproductive rate. These species try to fill all available niches in an environment. Examples of r-selected species are many weeds such a dandelions, insects such as house flies and cockroaches, mice, passenger In 1987, 18 black-footed ferrets, the last known individuals of this species, were captured and brought into a captive breeding program in Wyoming.

Plants such as dandelions are another good example of an r-selected species. You can see r- and K-selected strategies clearly by looking at different organisms within a phylogenetic group, such as the mammals. For example, elephants are highly K-selected, whereas mice are much more r-selected. Among the fishes, most, like the salmon, are r-selected.

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.
