We use age-structured population models to understand how fished populations respond to environmental variability. In general, fished populations exhibit greater variability than unfished populations, for two reasons: a) they are less dampened by density-dependent processes, and b) reproduction is concentrated into fewer ages, making it more likely that random events will ‘echo’ across generations. In this poster we share some preliminary analyses examining how no-take marine protected areas (MPAs) could reduce that variability by protecting part of the population from harvest. This is a potential example of how MPAs could provide resilience to environmental variability and climate change.
