There is a growing need for improved techniques to monitor coral reef restoration as these ecosystems and the goods services they provide continue decline under threats of anthropogenic activity climate change. Given difficulty fine-scale requirements survival spread outplanted branching fragments, Unoccupied Aerial Systems (UASs) an ideal platform spatially document quantitatively track growth patterns on shallow systems. We present findings from monitoring combining UAS data with object-oriented segmentation open-source GIS analysis quantify areal extent species-specific coverage across ~one hectare fringing over one-year period (2019–2020) in Laughing Bird Caye National Park, southern Belize. The results demonstrate detection cover changes three species (Acropora cervicornis, Acropora palmata, prolifera) around caye since 2006, overall target changing 2142.58 2400.64 square meters 2019 2020.

Advancing the coral propagation toolkit via hypersalinity induced coral micropropagates

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

In the face of escalating threats posed by human-induced climate change, urgent attention to coral reef restoration is imperative due ongoing degradation. Here, we explored potential generating micropropagates as a tool rapidly generate tissue for and engineering. We developed hypersalinity-induced polyp bailout protocol simple attachment device support growth on commonly used substrates. found that hypersalinity induction, at rate < 1 ppt hr -1 , produced healthy Stylophora pistillata . The highest success (~74%) was achieved in CaCO 3 substrate devices, which outperformed PVC (~48%) Portland cement (~5%). Settled displayed rapid rates both (0.037 mm²/day ± 0.002 SE) (0.057 0.008 substrates, while induced Our study provides detailed methodology reliably generating, attaching, growing underscores viable technique supporting propagation efforts.

Genet identity and season drive gene expression in outplanted Acropora palmata at different reef sites.

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: May 13, 2024

Coral reefs are experiencing decreases in coral cover due to anthropogenic influences. restoration is addressing this decline by outplanting large volumes of corals onto reef systems. Understanding how outplanted react at a transcriptomic level different outplant locations over time important, as it will highlight habitat affects the host and influences physiological measures. In study, dynamics four genets Acropora palmatawere assessed year three sites Florida Keys. Genet identity was more important than sampling or site, with differing levels baseline immune protein production key drivers. Once accounting for genet, enriched growth processes were identified winter, increased survival expression found summer. The effect site small, hypothesized differences autotrophic versus heterotrophic dependent on depth. We hypothesize that genotype an consideration restoration, gene could play role survivorship growth. Additionally, during cooler winter months may be beneficial higher processes, allowing establishment outplants system.

Tank fouling community enhances coral microfragment growth

PeerJ, Journal Year: 2023, Volume and Issue: 11, P. e15723 - e15723

Published: Aug. 7, 2023

Anthropogenic stressors threaten reefs worldwide and natural in situ coral reproduction may be inadequate to meet this challenge. Land-based culture can provide increased growth, especially with microfragments. We tested whether methods using different algal fouling communities could improve the growth health metrics of microfragments Hawaiian coral, Porites compressa. Culture method were: (1) similar a reef environment (Mini Reef); (2) clean tanks managed promote crustose coralline algae (Clean Start); (3) curated beforehand poorly-competing (Green Film) assessed winter summer months. The Green Film during produced fastest microfragment mean at 28 days until first row new polyps developed, also highest tank plate metric scores. Time efficient, standardized for land-based designed maximize production fragments will contribute considerably success large-scale restoration efforts.

Effectiveness of different nursery designs for the restoration of the threatened coral Acropora cervicornis in Culebra, Puerto Rico

Conservation Evidence Journal, Journal Year: 2023, Volume and Issue: 20, P. 30 - 39

Published: Jan. 1, 2023

The threatened staghorn coral Acropora cervicornis is an important reef-builder species in the Caribbean. Its ecological importance and critical status have prompted efforts to restore degraded populations. In this respect, nursery-based programmes effectively propagated A. helped increase population sizes. Despite many advances low-cost nursery designs, there still a need productivity while reducing costs. This study evaluates demographic performance two propagation structures: floating trees (FT) horizontal frames (HF). Two equal-sized fragments were collected from 50 healthy colonies. Each fragment was placed into FT or HF design. Survival, growth, branching, recorded for seven months. To address cost-effectiveness of techniques, we compared total cost producing corals between designs. Survival similar, with 91% 92% surviving HF, respectively. Although colonies nurseries grew faster produced more branches than those nurseries, these differences not statistically significant. Likewise, did differ designs despite being 1.5 times productive nurseries. Because similarity performance, selection could be based solely on their cost-effectiveness. analysis shows that using costs about 70% less FT. Thus, conclude frame (HF) are better propagating accelerating restoration activities.
