Climate Change, Coral Loss, and the Curious Case of the Parrotfish Paradigm: Why Don't Marine Protected Areas Improve Reef Resilience?

Annual Review of Marine Science, Journal Year: 2019, Volume and Issue: 11(1), P. 307 - 334

Published: Jan. 3, 2019

Scientists have advocated for local interventions, such as creating marine protected areas and implementing fishery restrictions, ways to mitigate stressors limit the effects of climate change on reef-building corals. However, in a literature review, we find little empirical support notion managed resilience. We outline some reasons why protection herbivorous fish (especially parrotfish) had effect coral One key explanation is that impacts (e.g., pollution fishing) are often swamped by much greater ocean warming Another sheer complexity (including numerous context dependencies) five cascading links assumed managed-resilience hypothesis. If reefs cannot be saved actions alone, then it time face reef degradation head-on, directly addressing anthropogenic change—the root cause global decline.

Consumer diversity interacts with prey defenses to drive ecosystem function

Ecology, Journal Year: 2013, Volume and Issue: 94(6), P. 1347 - 1358

Published: Jan. 17, 2013

Prey traits linking consumer diversity to ecosystem function remain poorly understood. On tropical coral reefs, herbivores promote dominance by suppressing competing macroalgae, but the roles of herbivore identity and diversity, macroalgal defenses, their interactions in affecting reef resilience are unclear. We studied adjacent pairs no-take marine reserves fished areas on reefs Fiji found that protected supported 7-17x greater biomass, 2-3x higher species richness herbivorous fishes, 3-11x more live cover than did reefs. In contrast, macroalgae were 27-61x abundant 3-4x species-rich When we transplanted seven common from into they rapidly consumed, suggesting rates herbivory (ecosystem functioning) differed inside vs. outside reserves. then video-recorded feeding activity same when reserves, assessed functional redundancy complementarity fishes consuming these macroalgae. Of 29 larger only four accounted for 97% consumption. Two unicornfish consumed a range brown parrotfish multiple red algae, rabbitfish green alga, with almost no diet overlap among groups. The two most chemically rich, allelopathic algae each single, different, fish species. This striking resulted differing tolerances chemical structural defenses.

Synergistic effects of reserves and connectivity on ecological resilience

Summary In light of the global extent and cascading effect our impact on environment, we design manage reserves to restore biodiversity functioning ecosystems. Mobile organisms link important processes across ecosystems, however, their roles in providing these services are often overlooked need know how they influence ecosystem functions reserves. Herbivorous fish play a key role coral reef seascapes. By removing algae, promote growth recruitment, help increase resilience. We examined connectivity with mangroves affected herbivore populations benthic succession reefs eastern Australia. surveyed assemblages, composition characterised recruitment at multiple levels mangroves, no‐take reserve areas open fishing. Our results show that enhanced biomass richness reserves, effects interacted herbivory protected near mangroves. Connectivity protection combined double roving herbivorous The grazing intensity drove trophic cascade reduced algal cover Synthesis applications . findings demonstrate resilience can be improved by managing both adjacent habitats together as functional seascape units. understanding landscapes resilience, explicitly incorporating into conservation decision‐making, may have greater success environmental restoration preservation actions.

The evolution of fishes and corals on reefs: form, function and interdependence

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2016, Volume and Issue: 92(2), P. 878 - 901

Published: March 11, 2016

Coral reefs are renowned for their spectacular biodiversity and the close links between fishes corals. Despite extensive fossil records common biogeographic histories, evolution of these two key groups has rarely been considered together. We therefore examine recent advances in molecular phylogenetics palaeoecology, place corals a functional context. In critically reviewing available phylogenetic evidence, we reveal marked congruence groups. one group consisting swimming vertebrates other colonial symbiotic invertebrates, have remarkably similar evolutionary histories. Paleocene Eocene [66-34 million years ago (Ma)] most modern fish coral families were present, both represented by wide range morphotypes. However, there is little evidence diversification at this time. By contrast, Oligocene Miocene (34-5.3 Ma), exhibited rapid lineage diversification. There also increasing reef area, occupation new habitats, cover, potentially, abundance. Functionally, Oligocene-Miocene appearance taxa associated with high-turnover fast-growth ecosystems colonization flats. It period that characteristics established. Most species, however, only arose last 5.3 (Myr; Plio-Pleistocene), average age species being Myr, just 1.9 Myr. While genetically distinct, phenotypic differences often limited to variation colour or minor morphological features. This suggests increase during Myr was not matched changes ecosystem function. For fishes, appears be central presence pigment patterns may driven Furthermore, lack over 5 raises questions role importance shaping future reefs.
