Abstract: In this work we consider ecological Allee-like dynamics under perturbations with random and nonrandom temporal arrangements but the same autocorrelation pattern. We show that populations are more vulnerable to extinction under perturbations with higher complexity. Accordingly, this result provides an insight toward the disentangling the distinction between correlation and complexity in extinction dynamics which, in turn, allows comprehending how randomness jeopardizes the long-run proliferation of organisms.
