Abstract

This commentary complements Ellis et al.’s two-tiered framework by using panel data and emphasizing the role of population density in decelerating life history (LH) strategy. We show that mortality cues and energetic constraints do not operate in isolation, demonstrating how density-dependent competition shapes LH strategies over time and underscoring the need for a dynamic, multifaceted approach to LH development.
