Coral reefs provide ecosystem benefits to millions of people but are threatened by rapid environmental change and ever-increasing human pressures. Restoration is becoming a priority strategy for coral reef conservation, yet implementation remains challenging it increasingly apparent that indirect conservation restoration approaches will not ensure the long-term sustainability reefs. The important role conditions in practice currently undervalued, carrying substantial implications success. Giving paramount importance conditions, particularly during pre-restoration planning phase, has potential bring about considerable improvements innovation. This Essay argues risk may be reduced adopting an environmentally aware perspective gives historical, contemporary, future context decisions. Such approach open up new opportunities with improved have capacity dynamically respond trajectories.

A phenomic modeling approach for using chlorophyll-a fluorescence-based measurements on coral photosymbionts

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: March 2, 2023

We test a newly developed instrument prototype which utilizes time-resolved chlorophyll- fluorescence techniques and fluctuating light to characterize Symbiodiniaceae functional traits across seven different coral species under cultivation as part of ongoing restoration efforts in the Florida Keys. While traditional only provide handful algal biometrics, system protocol we have generates > 1000 dynamic measurements short (~11 min) time frame. Resulting ‘high-content’ biometric data revealed distinct phenotypes, broadly corresponded genus-level designations determined using quantitative PCR. Next, from Acropora cervicornis (10 genotypes) A. palmata (5 fragments was correlated with bleaching response metrics collected after two month-long exposure high temperature. A network analysis identified 1973 correlations (Spearman R 0.5) between biometrics various metrics. These biomarkers thermal stress were then utilized train predictive model, when tested against same fragments, yielded correlation (R = 0.92) measured (reductions absorbance by chlorophyll-a). When applied all species, model ranked dominated Cladocopium or Breviolum symbionts more susceptible than corals harboring thermally tolerant ( Durusdinium ). direct testing predictions on novel genotypes is still needed, our device modeling pipeline may help broaden scalability existing approaches for determining tolerance reef corals. Our analytical aligns recent assessments that call development tools improving programs.

Trade-offs in a reef-building coral after six years of thermal acclimation

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 949, P. 174589 - 174589

Published: July 7, 2024

There is growing evidence that reef-building corals can acclimate to novel and challenging thermal conditions. However, potential trade-offs accompany acclimation remain largely unexplored. We investigated physiological in colonies of a globally abundant coral species (Pocillopora acuta) were acclimated ex situ an elevated temperature 31 °C (i.e., 1 above their bleaching threshold) for six years. By comparing them conspecifics maintained at cooler temperature, we found the energy storage was prioritized over skeletal growth temperature. This associated with formation higher density skeletons, lower calcification rates consequently extension rates, which entails ramifications future processes, structural complexity reef community composition. Furthermore, symbionts physiologically compromised had overall reserves, likely due increased exploitation by host, resulting stress resilience holobiont. Our study shows how biological unfold, helping refine our picture trajectories. Importantly, observations this six-year do not align short-term studies, where temperatures often depletion highlighting importance studying organisms relevant scales.

Corals that survive repeated thermal stress show signs of selection and acclimatization

PLoS ONE, Journal Year: 2024, Volume and Issue: 19(7), P. e0303779 - e0303779

Published: July 31, 2024

Climate change is transforming coral reefs by increasing the frequency and intensity of marine heatwaves, often leading to bleaching mortality. Coral communities have demonstrated modest increases in thermal tolerance following repeated exposure moderate heat stress, but it unclear whether these shifts represent acclimatization individual colonies or mortality thermally susceptible individuals. For corals that survive events, important understand how past responses impact future growth potential. Here, we track 1,832 leeward Maui through multiple heatwaves document patterns survivorship over a seven-year period. While find limited evidence at population scales, reduced time specific individuals indicative acclimatization, primarily stress-tolerant taxa Porites lobata . survived both no relationship between response three four studied.

Coral micro-fragmentation assays for optimizing active reef restoration efforts

PeerJ, Journal Year: 2022, Volume and Issue: 10, P. e13653 - e13653

Published: July 18, 2022

The global decline of coral reefs has driven considerable interest in active restoration. Despite their importance and dominance on mature reefs, relatively few restoration projects use slower growth forms like massive encrusting species. Micro-fragmentation can increase cover by orders magnitude faster than natural growth, which now allows cultivation slow growing shows promise flexibility for reef However, the major causes variation survival outplanted colonies remain poorly understood. Here, we report simple outplanting assays to aid species likelihood success. We used two different micro-fragmentation assays.

Contingency planning for coral reefs in the Anthropocene; The potential of reef safe havens

Emerging Topics in Life Sciences, Journal Year: 2022, Volume and Issue: 6(1), P. 107 - 124

Published: Feb. 28, 2022

Reducing the global reliance on fossil fuels is essential to ensure long-term survival of coral reefs, but until this happens, alternative tools are required safeguard their future. One emerging tool locate areas where corals surviving well despite changing climate. Such locations include refuges, refugia, hotspots resilience, bright spots, contemporary near-pristine and hope spots that collectively named reef ‘safe havens' in mini-review. Safe havens have intrinsic value for reefs through services such as environmental buffering, maintaining conditions, or housing naturally adapted future conditions. Spatial temporal variance physicochemical conditions exposure stress however preclude certainty over ubiquitous capacity safe maintain protective service provision. To effectively integrate into proactive management contingency planning climate change scenarios, thus requires an understanding differences, potential values, predispositions stress. purpose, I provide a high-level review defining characteristics different havens, how they being utilised what risk susceptibilities inherently have. The mini-review concludes with outline haven habitats support under uncertain from intensifying change.
