An abundant mutualist can protect corals from multiple stressors

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2040)

Mutualisms can increase the ability of foundation species to resist individual stressors, but it remains unclear whether mutualisms also ameliorate co-occurring stressors for habitat-forming species. To examine a suspected mutualist could improve species’ resistance multiple we tested how common coral-dwelling crab affected corals exposed macroalgal contact and physical wounding during widespread heat stress event using flow-through tanks supplied with seawater from nearby reef flat. High temperatures on flat, which raised temperature in our tanks, appeared trigger rapid tissue loss experimental corals, amount lost by was strongly determined treatment. Macroalgal increased, while presence decreased, lost. Although effect not strong isolation, when occurred crab, coral unexpectedly decreased below that all other treatments. We propose increased attracting crabs—a result supported field experiment. These results highlight interact unexpected ways, buffering effects both local global

Employing invertebrates to restore herbivory on Caribbean coral reefs: recent developments and remaining barriers

Restoration Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: April 2, 2025

With coral reefs in global decline and further threatened by growing anthropogenic impacts, effective strategies for restoring these critical ecosystems are increasingly sought after. In Caribbean reefs, where disease outbreaks fishing pressure have reduced herbivore abundances facilitated widespread phase shifts from to algal dominance, herbivorous invertebrates gained recent attention as a promising restoration tool. However, many practitioners face challenges evaluating the feasibility anticipated outcomes of integrating invertebrate herbivores into their programs. Here we review developments regarding species techniques identify remaining barriers that require research before enhancement can be considered scalable strategy reefs. Bottlenecks mariculture processes remain larval juvenile rearing stages impede scalability production, with significant outstanding across all terms stocking effectiveness monitoring feasibility. Integrating alternative ameliorate some bottlenecks, investigating culture grazing additional holds notable opportunities. Across initiatives, ecological objectives viable measuring against needed. These findings establish priorities husbandry communities alike provide guidance rapidly evolving field restoration.

Runaway Climate Across the Wider Caribbean and Eastern Tropical Pacific in the Anthropocene: Threats to Coral Reef Conservation, Restoration, and Social–Ecological Resilience

Atmosphere, Journal Year: 2025, Volume and Issue: 16(5), P. 575 - 575

Published: May 11, 2025

Marine heatwaves (MHWs) are increasingly affecting tropical seas, causing mass coral bleaching and mortality in the wider Caribbean (WC) eastern Pacific (ETP). This leads to significant loss, reduced biodiversity, impaired ecological functions. Climate models forecast a troubling future for Latin American reefs, but downscaled projections WC ETP remain limited. Understanding regional temperature thresholds that threaten reef futures restoration efforts is critical. Our goals included analyzing historical trends July–August–September–October (JASO) anomalies exploring at subregional country levels. From 1940 2023, JASO air ocean showed increases. Projections indicate even under optimistic scenario 4.5, temperatures may exceed +1.5 °C threshold beyond pre-industrial levels by 2040s +1.0 annual maximums 2030s, resulting severe mortality. Business-as-usual 8.5 suggests conditions will become intolerable conservation with decadal warming largely surpassing rates, unbearable corals.

Exploring the potential of native sea urchins as ex situ coral propagation allies

Caribbean coral reefs face unprecedented decline due to anthropogenic and environmental stressors, necessitating active restoration efforts. Among the strategies conserve restore reef ecosystems, land‐based sexual propagation of corals is crucial for preserving genetic diversity population resilience. This study explores efficacy utilizing native sea urchin herbivory control benthic macroalgal proliferation enhance growth in systems. Three captive‐reared species— Lytechinus variegatus , Tripneustes ventricosus Diadema antillarum —were evaluated their influence on algal cover sexually propagated brain Pseudodiploria strigosa . Juveniles each species were co‐cultured with 6‐month‐old colonies over a 105‐day experiment. Results indicated that all treatments effectively reduced compared controls; however, only T. significantly increased rate, while other did not have notable effect. Despite differences growth, survival was consistently high across treatments. Benthic community analysis revealed shifts composition, D. grazing associated crustose coralline algae. However, overgrazing by may resulted mild peripheral tissue damage some corals. Urchin remained high, suggesting potential downstream utilization (e.g. enhancement). highlights urchins as biocontrol agents propagation, emphasizing importance species‐specific interactions shaping communities promoting
