Key Concepts

r-Selection Strategy

This strategy is characterized by high reproductive rates, producing many offspring with minimal parental care. It is favored in unpredictable or unstable environments where rapid population increases can take advantage of sudden resource availability, but individual survival is low due to environmental uncertainties.

K-Selection Strategy

This strategy involves producing fewer offspring with significant parental care and investment. It is favored in stable, predictable environments where competition for resources is intense, and traits that enhance survival and competitive ability when the population is near the environment's carrying capacity are advantageous.

Environmental Predictability

Environmental predictability relates to how stable or fluctuating an ecosystem is. Organisms in unpredictable environments tend to adopt an r-selection strategy, maximizing reproduction to ensure that some offspring survive. In contrast, in predictable, competitive environments, a K-selection strategy is more adaptive, emphasizing quality over quantity in offspring production.
