Abstract The concept of regulation is used in biology to explain properties such as stability, robustness, and long-term persistence of biological systems. Regulation claims often focus, however, on the capabilities of these systems, rather than the mechanisms underlying them. In an attempt to produce a full-fledged theoretical account of regulation, a stricter concept has been proposed by Bich and colleagues based on the theory of biological autonomy. According to these authors, regulation is exerted by specialized subsystems that can change the constitutive regime of a system (enabling it to deal with a wider range of perturbations) but whose dynamics are not specified by the latter. In this paper, we present a brief survey on how regulation has been treated in biology and, more specifically, in ecology. We show how the ecological literature attributes regulatory powers either to organismic phenomena or to the propagation of perturbations through the network of relations in ecological systems. We were not able to find any study proposing a specialized subsystem dedicated to regulation in an ecological system. This raises doubts about the feasibility of a regulatory subsystem such as conceived by Bich and colleagues. Nonetheless, we argue that ecological systems may encompass more than just dynamic stability and feedback mechanisms, such that it can be worthy applying their concept to investigate regulation in these systems.
