Populations

A specialist species with a narrow ecological niche.

A K-selected species with high parental investment.

A generalist species with a broad ecological niche.

An r-selected species with a low reproductive rate.

Early maturity

High reproductive rate

Low parental care

Long lifespan

Long lifespan

High parental care

Many offspring

Slow maturation

K-selected species thrive in unstable environments due to their high reproductive rates.

r-selected species are better suited to stable environments because of their long lifespans.

K-selected species are better suited to stable environments due to their competitive ability and longer lifespans.

r-selected species thrive in stable environments due to their ability to invest heavily in parental care.

K-selected species would likely recover more quickly due to their high reproductive rates.

r-selected species would likely be more vulnerable due to their specialized diets.

K-selected species would likely be more resilient due to their longer lifespans and greater ability to withstand environmental changes.

r-selected species would likely recover more quickly due to their ability to reproduce rapidly and colonize disturbed areas.
