Coral Conservation: Global evidence for the effects of actions provides an essential resource anyone dedicated to conserving or restoring corals. This comprehensive synthesis global scientific examines effectiveness conservation and restoration targeting stony, soft cold-water coral species inhabiting a diverse range marine habitats in tropical, temperate arctic waters from shallow coasts deep sea. Addressing urgent threats posed by climate change, invasive species, overfishing, habitat destruction, this work summarizes three core themes: protecting healthy reefs, mitigating human impacts, undertaking active restoration. From establishing Marine Protected Areas innovative techniques like gardening, synopsis practical offers insights into their outcomes applicability. Designed guide decision-makers—resource managers, conservationists, policymakers, local advocates—as well as those curious learn about that could help corals, accessible succinct information support evidence-based conservation.

Coral predation and implications for restoration of Kenyan reefs: The effects of site selection, coral species and fisheries management

Journal of Experimental Marine Biology and Ecology, Journal Year: 2023, Volume and Issue: 566, P. 151924 - 151924

Published: July 6, 2023

Active coral reef restoration is increasingly applied for local management, but remains hampered by biological interactions such as predation (corallivory). To determine factors that drive corallivory and develop more ecology-based approaches, corallivore communities were characterized fish bite mark densities quantified on natural colonies fragments outplanted small artificial structures. Six study sites distributed equally among three levels of fisheries management at southern Kenyan reefs (fished < reserve no-take). Obligate corallivorous strongly correlated with cover regardless level, whereas facultative (mainly parrotfish) most abundant in no-take zones. High snail associated low diversity sea stars scarce. Bite clearly higher branching corals, did not correlate to cover, or densities. Compared colonies, pressure was up 24-fold greater especially fierce inside This high live tissue fragments. These results demonstrate often targeted restoration, do necessarily experience improved outplanting methods species considerations are needed address The interplay between warrants further scrutiny: while obligate unlikely detrimental recovery, could hamper efforts.

The blue economy is built on the principle that socio-economic progress can occur in tandem with environmental protection and sustainable resource extraction. Nations coastal ocean-based economies have struggled to realize promise of without taking conciliatory measures. Island nations are especially affected due their overwhelming reliance marine tourism related activities disproportionate susceptibility climate change fluctuating touristic demands. Not all island same national ocean be vastly different, dictated by complex geopolitics, cultural models, social value systems. We explore these facets further through two contrasting case studies from remarkably different corners world—the Mauritius western Indian Ocean Pacific Countries Territories. recommend tourism, largest component Islands' economy, must handled as an anthropogenic stressor subject assessments, regulatory enforcement, adaptive mitigation Further, fees levied should proportionally allocate funds towards periodic monitoring restoration evaluation studies.

Effects of territorial damselfish on corallivorous fish assemblage composition and coral predation in the Mauritian lagoon

Journal of Experimental Marine Biology and Ecology, Journal Year: 2023, Volume and Issue: 569, P. 151960 - 151960

Published: Oct. 26, 2023

Predation is a significant stressor for many coral species. Understanding how predation interacts with factors such as climate change key to conservation. Territorial damselfish of the genus Stegastes form territories on branching corals (genus Acropora) which they cultivate algae, and while defending these territories, provide indirect protection from predation. However, it not known afforded by spp. varies corallivorous fish assemblage composition, nor whether corallivore assemblages themselves may be affected presence their associated Acropora habitats. This study examined relationships among spp., cover, number species richness present within given area, namely Mauritian lagoon in western Indian Ocean. bleaching-resilient massive Porites lutea outside was surveyed at sites around Mauritius island. Corallivorous assemblages, density were also each site visit. Results show that high correlated numbers corallivores, but lower irrespective all observed densities. Greater increasing obligate corallivores. Non-Acroporid cover positively negatively overall density. shows first time regardless corallivores present, adding growing body knowledge complex between environment. The findings indicate possible effects habitats areas low diversity, warrant further study.
