Analysis of 15,066 reef surveys during 2014-2017 revealed that 80% of surveyed reefs experienced significant coral bleaching and 35% experienced significant coral mortality.

This study investigates, for the first time, the photobiology of symbiotic zoanthids inhabiting different tidal environments: subtidal, intertidal pools and intertidal areas exposed to air during low tide. More specifically, we assessed the photochemical efficiency, Symbiodinium density and photosynthetic pigments profile of Zoanthus sociatus during low tide. Photochemical efficiency was lower and cell density higher in air exposed zoanthids. The profile of photosynthetic pigments also varied significantly among tidal habitats, particularly photoprotective pigments such as dinoxanthin and diadinoxanthin.

The CPI differentiates between sites on the basis of strength or weakness of surrogates for desirable attributes such as benthic biodiversity, reef-building capacity and hard-coral resilience. 3. Biodiversity and reef-building attributes (more is better) were assigned progressive weightings (high abundance, high score), whereas neutral or detrimental attributes (less is better) were assigned regressive weightings (high abundance, low score). 4. Abundance of small corals (new recruits and remnants) was included as an indicator of a site's potential for recovery following disturbance. 5. The CPI rankings were used in conjunction with multidimensional scaling to prioritize candidate sites for a proposed reserve network near Salvador, Brazil. The information is complementary to considerations of existing uses and socioeconomic considerations, in the prioritization of reefs for protection. 6. The approach ensured that ecological inputs to the broader marine spatial planning process embraced both representativeness of biodiversity per se and the investigator's evaluation of key qualitative site attributes (amount, size, and resilience indicators for the critical architectural components hard coral and encrusting coralline algae).","impression_tracking_id":null,"owner":{"id":4258674,"first_name":"ruy","middle_initials":null,"last_name":"kikuchi","page_name":"ruykikuchi","domain_name":"ufba","created_at":"2013-05-20T21:25:21.789-07:00","display_name":"ruy kikuchi","url":"https://ufba.academia.edu/ruykikuchi"},"attachments":[{"id":87653114,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/87653114/thumbnails/1.jpg","file_name":"aqc.241720220617-1-b29yjv.pdf","download_url":"https://www.academia.edu/attachments/87653114/download_file","bulk_download_file_name":"Reef_quality_criteria_for_marine_reserve.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/87653114/aqc.241720220617-1-b29yjv-libre.pdf?1655475803=\u0026response-content-disposition=attachment%3B+filename%3DReef_quality_criteria_for_marine_reserve.pdf\u0026Expires=1744369227\u0026Signature=QTtjHRgHosctlrV2M54Ea4Bbar3yCRWSLy0WoGn5UNJx854DmGOHHuDcfVbdKDF-yebMf3X62b8tGlbL8GQ96cXSQDJ2Ka-N2D23Afz14LPZdW2FLYngnjZqzGOVzFocC01awOABQ~kjkuHRFwc8B2hOQIpwy8GyhgJNcJKDZ~oGFa0eFciSyeWaHSizjdnkmP7yHooYSDPEWGD0vl4U~vSt8gOUBJ9XaxZt9IU05zQ80-jCtR5Z5~YHiUbT~36ofAj3mEDqnql23DoBPzjWEiRmPm4Y~CSxTmLpyMvJf5C9psHtSdMWRnEcnbs~ZVuwMmbsWhSfQGxjlXswc9bgVA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":261,"name":"Geography","url":"https://www.academia.edu/Documents/in/Geography"},{"id":2467,"name":"Conservation Biology","url":"https://www.academia.edu/Documents/in/Conservation_Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"},{"id":22305,"name":"Marine Reserves","url":"https://www.academia.edu/Documents/in/Marine_Reserves"},{"id":47884,"name":"Biological Sciences","url":"https://www.academia.edu/Documents/in/Biological_Sciences"},{"id":58054,"name":"Environmental Sciences","url":"https://www.academia.edu/Documents/in/Environmental_Sciences"},{"id":180145,"name":"Ecological Integrity","url":"https://www.academia.edu/Documents/in/Ecological_Integrity"},{"id":214444,"name":"Conservation of Aquatic Resources","url":"https://www.academia.edu/Documents/in/Conservation_of_Aquatic_Resources"},{"id":418764,"name":"Marine spatial planning","url":"https://www.academia.edu/Documents/in/Marine_spatial_planning"},{"id":831525,"name":"Conservation Targets","url":"https://www.academia.edu/Documents/in/Conservation_Targets"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-81698778-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="81698777"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/81698777/Effect_of_phase_shift_from_corals_to_zoantharia_on_reef_fish_assemblages"><img alt="Research paper thumbnail of Effect of phase shift from corals to zoantharia on reef fish assemblages" class="work-thumbnail" src="https://attachments.academia-assets.com/87653210/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/81698777/Effect_of_phase_shift_from_corals_to_zoantharia_on_reef_fish_assemblages">Effect of phase shift from corals to zoantharia on reef fish assemblages</a></div><div class="wp-workCard_item"><span>PloS one</span><span>, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Consequences of reef phase shifts on fish communities remain poorly understood.

PAM flourometry in situ was used to examine the photobiology of the most dominant coral species throughout the platform surfaces and bases of Abrolhos' characteristic 'chapeirões' reef framework; however, none of the species consistently adhered to the 'clear water paradigm'. PAM measurements further demonstrated that species conformed to two different strategies of non-photochemical energy dissipation: transient but relatively rapid for the two closely related endemic species (Mussismilia braziliensis and Mussismilia harttii) as opposed to more persistent for Montastrea cavernosa, Porites astreoides and Siderastrea stellata.

Each reef was considered a sample unit and species densities per 100 m² was used for calculating true diversity measures.

However, they are also opportunities to better understand how communities are structured. In Southwest Atlantic coral reefs, a shift to the zoanthid Palythoa cf. variabilis dominance has been described. To test if competition drove this process, we carried out a manipulative experiment with three coral species. To estimate the natural frequency of encounters we assess the relationship between the proportion of encounters and this zoanthids coverage. The contact causes necrosis in 78% of coral colonies (6.47 ±SD 7.92 cm²) in 118 days. We found a logarithmic relationship between the proportion of these encounters and the cover of P. cf. variabilis, where 5.5% coverage of this zoanthid is enough to put 50% of coral colonies in contact, increasing their partial mortality.

The group concluded that identifying and evaluating the regional effects of OA is impossible without understanding the natural variability of seawater carbonate systems in marine ecosystems through a series of long-term observations.

Studies on the causes, effects and consequences of phase shifts on reef fish communities have only been considered for coral-to-macroalgae shifts. Therefore, there is a large information gap regarding the consequences of novel phase shifts and how these kinds of phase shifts impact on fish assemblages. This study aimed to compare the fish assemblages on reefs under normal conditions (relatively high cover of corals) to those which have shifted to a dominance of the zoantharian Palythoa cf. variabilis on coral reefs in Todos os Santos Bay (TSB), Brazilian eastern coast.

PAM flourometry in situ was used to examine the photobiology of the most dominant coral species throughout the platform surfaces and bases of Abrolhos' characteristic 'chapeirões' reef framework; however, none of the species consistently adhered to the 'clear water paradigm'. PAM measurements further demonstrated that species conformed to two different strategies of non-photochemical energy dissipation: transient but relatively rapid for the two closely related endemic species (Mussismilia braziliensis and Mussismilia harttii) as opposed to more persistent for Montastrea cavernosa, Porites astreoides and Siderastrea stellata. Further experiments demonstrated that tolerance to anomalous stress amongst species did not correspond with the non-photochemical energy dissipation strategy present but was consistent with the relative dominance of species within the chapeirões coral communities.

Indicators of reef vitality reveal that reefs located less than 5 km from the coastline, the inshore reefs, are in poorer conditions than those located more than 5 km off the coast, the offshore reefs. The inshore reefs are the most impacted by the effects of eutrophic waters associated with sewage pollution, high sedimentation rates and water turbidity, and the most exposed to the effects of bleaching and infectious diseases.
