| The concept of resilience continues to crescendo since the 1990s, touching on multiple fields with multiple interpretations and uses. Here, we start from its origins in systems ecology, framing the resilience concept explicitly in the adaptive cycle with the observation that resilient systems are ones that successfully navigate all stages of growth, development, collapse, and reorientation of this cycle. The model is explored in terms of the traps and pathologies that hinder this successful navigation, particularly when applied to socioeconomic organizations and decision-management situations. For example, for continuous function over the adaptive life cycle, a system needs activation energy or resources to grow, followed by adequate structure and... |

| Experience has established that the recovery of many collapsed stocks takes much longer than predicted by traditional fishery population models. We put forward the hypothesis that stock collapse is associated with disruption of the biological mechanisms that sustain life-cycle closure of intrapopulation contingents. Based on a review of case studies of nine marine fish stocks, we argue that stock collapses not only involve biomass loss, but also the loss of structural elements related to life-cycle diversity (contingents), as well as the breakdown of socially transmitted traditions (through a curtailed age range). Behavioural mechanisms associated with these structural elements could facilitate recovery of depleted populations. Migratory behaviour is... |
