The eco-evolutionary dynamics of stoichiometric homeostasis

Andrés López-Sepulcre et al. Trends Ecol Evol. 2024 Dec.

Abstract

Stoichiometric homeostasis is the ability of life to maintain inner chemical constancy despite changes in the environment and resources. Organisms can be stoichiometrically homeostatic to different degrees. This variation can be substantial even within species, but is ignored in most studies of ecological stoichiometry. Recent studies suggest that resource limitations are an important selective pressure behind homeostasis, but are contradictory in direction, likely owing to differences in nutrient storage strategies. Understanding the selective pressures underlying stoichiometric homeostasis, and its potential for rapid evolution, are key to predicting eco-evolutionary dynamics. This calls for the development of an evolutionary theory of stoichiometric homeostasis that incorporates rapid evolution, as well as for empirical studies to test the underlying mechanisms.

Keywords: G×E interaction; consumer-driven nutrient recycling; eco-evolutionary dynamics; elemental homeostasis; nutrient limitation; rapid evolution.
