What Are R-selected Species? R-selected species also referred to as r-strategists are species whose populations are governed by their biotic potential (maximum reproductive capacity, r). 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 little or no parental care), and possess short life spans. Unlike K-selected species, … Read more
