r/K Selection Theory

The r/K selection theory, a concept in ecology, delineates contrasting reproductive strategies adopted by organisms to thrive in varying environmental conditions. It posits two distinct approaches: r-strategists, prioritizing high reproductive rates in unstable habitats, and K-strategists, favoring fewer offspring with enhanced parental care in stable environments. This theory, initially proposed by Robert MacArthur and E. O. Wilson, has since spurred extensive research across disciplines, from evolutionary biology to economics. In this introductory exploration, we delve into the core tenets of r/K selection theory, elucidating its implications for species dynamics, population ecology, and evolutionary adaptation.
