What are opportunistic or r-selected species?

Answer 1

R-selected or opportunistic species are species that have high growth rates, produce many offspring, and have low survival odds for those many offspring.

R-selected or opportunistic species are species that have high growth rates, produce many offspring, and have low survival odds for those many offspring. These species typically have little parental care and reproduce often.

Examples include bacteria, many plants, and most insects.

R-selected species can be contrasted with k-selected species which have slower growth rates, produce few offspring with increased parental care and higher survival odds, and that reproduce at longer intervals.

Examples of k-selected species include mammals such as humans, dolphins, and rhinos.

Opportunistic or r-selected species are organisms that reproduce rapidly when environmental conditions are favorable. They typically produce large numbers of offspring, but invest relatively little in each offspring's survival. These species are often adapted to unstable or unpredictable environments.
