Definition

Environmental harshness: externally caused levels of morbidity and mortality in a population.

Introduction

Environmental harshness is one of the major components of an ecology implicated in guiding an organism’s life history decisions. As such, an organism’s experience with cues of harshness in an environment during critical periods of ontogeny is capable of modifying developmental trajectories and energy budget tradeoffs (Ellis et al. 2009). In humans, encountering harshness and unpredictability has also been revealed to predispose an individual to a suite of psychological tendencies: impulsivity, risk-taking, and the propensity to discount delayed rewards (Griskevicius et al. 2011b, 2013). Harshness emerges as a principal characteristic of an ecology’s profile that predicts both between-species and within-species variation in life history strategies (Ellis et al. 2009).
