Which effect diminishes effectiveness if marine protected areas are declared within strong oceanic gyres?

💡 Explanation

When marine protected areas are within strong gyres, the strong circular currents cause increased mixing and reduced larval retention because the larval dispersal is far greater than contained within the protected zone. Therefore the larval dispersal distances increase beyond MPA boundaries, rather than increased upwelling, decreased temperature change, or increase predator introduction due to transport patterns involved in gyre dynamics.
