Faut-il postuler un ordre écologique pour expliquer la persistance des écosystèmes ?

Abstract : The idea of a natural order which is not tantamount to the physical order often sounds suspicious. However, I argue that a kind of ecological organicism is necessary if we want to explain the persistence of ecosystems. This persistence of ecosystems is puzzling when it comes to thermodynamics and population dynamics. Characterizing the ecological order as the spontaneous order of dissipative systems cannot provide the appropriate explanation. This is why I suggest an alternative characterization: ecosystems are organized beings. This idea takes the form of the hypothesis that ecosystems are self-constrained systems: they produce a part of the constraints which channel the thermodynamic flows that go through them. This self-constraint enables the ecosystems to persist in spite of population fluctuations and thermodynamic non-equilibrium.
