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.
期刊介绍：
Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
