• Cumulative thermal stress predicts functional change in coral reef fish communities

  Marine heatwaves shift coral reef fish communities toward herbivores at the expense of corallivores, altering functional composition that reef resilience depends on. A Bayesian model across multiple species and locations provides predictive insight into how thermal stress reorganizes fish communities.

• Marine heat waves in vulnerable coral reef regions are skillfully predictable on multi-year timescales

  Marine heatwave frequency and intensity in coral reef regions are predictable on multi-year timescales using Earth system models, with skill varying by region. Extended forecasting could enable proactive reef management and conservation planning.

• Density patterns and age structure of the queen conch ( Aliger gigas ) in a coral reef lagoon in the Mexican Caribbean

  Queen conch populations in a Mexican Caribbean lagoon show recovery during and after a 5-year fishing closure, with density and age structure tracked across reefs. Population response to protection measures informs management of this overexploited Caribbean resource.

• “Our findings show why fisheries managers need to consider more than temperature alone,” William Cheung…

  UBC researcher William Cheung finds fisheries must consider multiple environmental extremes beyond temperature alone. Knowledge of how environmental stressors interact helps predict reef-ecosystem responses and fisheries impacts on reef communities.

• Contribución de la ictiofauna arrecifal a los servicios ecosistémicos del Sistema Arrecifal Mesoamericano

  A study quantifies how reef fish species in the Mesoamerican Reef contribute to ecosystem services including fisheries, coastal protection, and nutrient cycling. Assigning ecological value species-by-species helps prioritize conservation in a degraded reef system.

• The #Arctic workshop at #PICES2026 was today

  A PICES workshop examined Arctic climate impacts including sea ice loss and ocean acidification affecting fisheries and Indigenous communities. Ocean acidification is reef-relevant, though the Arctic context is distant from tropical reefs.

• An innovative approach to tackling the marine conservation problem of "ghost gear" is gaining acceptance in…

  Canada develops new permitting pathways for ghost-gear removal as marine-habitat offset. Ghost fishing impacts reef ecosystems; understanding removal as conservation credit advances reef restoration frameworks.

• Subsidies that fuel overfishing and damage coral reefs and mangroves are costing governments and societies…

  Fishing subsidies cost governments far more in environmental damage than they spend, harming coral reefs and mangroves. The economics are dense, but the scale of subsidy-driven reef destruction is worth tracking.
