摘要: No-take marine reserves in Moreton Bay were established to conserve and restore the structure function of ecosystems ensure sustainable social-ecological systems (Ross et al. 2019, this volume). Here, we review published literature determine our current understanding how no-take (i.e. green zones) benefit fish, shape ecological functions numerous within Marine Park. Over past decade, 16 peer-reviewed studies have examined ‘reserve effects’ for fish associated processes Bay; work was mostly conducted central part coral reefs seagrass meadows. Most showed enhanced abundance, diversity, or both, inside increases levels performed by (e.g. greater grazing rates). The degree which enhance abundance their contingent on two key conditions. Reserves that better connected those proximity complementary habitat types situated a more complex seascape) located clearer water typically perform may also be resilient. Therefore, these factors must strongly considered during future deliberations about expanding modifying Bay. We identify number information gaps are likely impede improvement network reserves, namely, research sandy muddy bottoms, ocean beaches, fishing outside pivotal other than herbivory. Reserve design rezoning can take advantage considerable body evidence gathered governing reserve performance fishes, but effects need habitats been overlooked. How broader range functions, productivity, resilience needs investigated.
