We found that during this bleaching event, rates of NEP and NEC across replicate transects remained positive and did not change in response to bleaching. Repeated benthic surveys over a period of 20d indicated an increase in the percent area of bleached coral tissue, corroborated by relatively low Symbiodiniaceae densities (1/40.6×106cm-2) and dark-adapted photosynthetic yields in photosystem II of corals (1/40.5) sampled along each transect over this period. Given that a clear decline in coral health was not reflected in the overall NEC estimates, it is possible that elevated temperatures in the water column that compromise coral health enhanced the thermodynamic favorability for calcification in other ahermatypic benthic calcifiers. These data suggest that positive NEC on degraded reefs may not equate to the net positive accretion of a complex, three-dimensional reef structure in a future, warmer ocean. Critically, our study highlights that if coral cover continues to decline as predicted, NEC may no longer be an appropriate proxy for reef growth as the proportion of the NEC signal owed to ahermatypic calcification increases and coral dominance on the reef decreases.]]> Wed 30 Aug 2023 15:01:01 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45128 Wed 26 Oct 2022 16:24:39 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41216 Wed 07 Feb 2024 16:19:50 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38161 Wed 04 Aug 2021 18:44:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51270 Wed 01 May 2024 15:33:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36576 Tue 09 Jun 2020 11:40:47 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37216 Tue 01 Sep 2020 14:51:26 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41833 Thu 18 Aug 2022 10:04:59 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44049 Thu 16 May 2024 10:49:13 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46512 Thu 16 May 2024 10:32:29 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54032 Mon 29 Jan 2024 13:32:39 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46613 Cladocopium sp. (syn. clade C3) within the host coral Acropora aspera during exposure to thermal stress. Exposure to temperatures between 2 and 3°C below the bleaching threshold, equating to 2-degree heating weeks (DHWs), results in changes to the symbiont cell morphology and cell division rates. Once corals were exposed to 4 DHWs, over 90% of the symbiont cells showed signs of degradation. Although sub-bleaching thermal stress is not sufficient to trigger bleaching alerts at an ecological scale, this stressor substantially affects the coral symbiosis. It is therefore vital that we begin to quantify how sub-bleaching thermal stress affects the fitness of Symbiodiniacea populations, their coral hosts and subsequently reefs worldwide.]]> Mon 28 Nov 2022 10:36:55 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50226 Mon 10 Jul 2023 11:13:00 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50224 Mon 10 Jul 2023 10:59:29 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52297 Mon 09 Oct 2023 10:11:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42819 Mon 05 Sep 2022 11:21:26 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37588 Mon 03 Apr 2023 13:16:07 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41291 96%) (environmentally responsive community) of the species-specific microbiome were in fact not found in association with the majority of individuals of the species. Only 0.1% (~21 phylotypes) of the species-specific microbiome of each species was shared among all individuals of the species (core microbiome), equating to ~3.4% of the resident microbiome. We found taxonomic redundancy and consistent patterns of composition, structure, and taxonomic breadth across individual microbiomes from the three coral species. Our results demonstrate that the coral microbiome is structured at the individual level. Importance: We propose that the coral holobiont should be conceptualized as a diverse transient microbial community that is responsive to the surrounding environment and encompasses a simple, redundant, resident microbiome and a small conserved core microbiome. Most importantly, we show that the coral microbiome is comparable to the microbiomes of other organisms studied thus far. Accurately characterizing the coral-microbe interactions provides an important baseline from which the functional roles and the functional niches within which microbes reside can be deciphered.]]> Mon 01 Aug 2022 12:02:22 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45456 Fri 28 Oct 2022 14:23:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52658 Fri 20 Oct 2023 09:09:29 AEDT ]]>
