Compound Hypoxia With Heat or Acidification Stress Induces Synergistic and Additive Effects on Coral Physiology

Multi-stressor experiments on three coral species demonstrate hypoxia produces mostly additive effects with acidification but synergistically amplifies physiological stress under elevated temperature...

Leveraging thermal regimes and connectivity networks to promote evolutionary adaptation across coral reef seascapes

As marine heat waves intensify, coral reef adaptation may struggle to keep pace. This perspective presents an operational framework that integrates heat-wave exposure and larval dispersal patterns to identify reef functional roles and management needs, helping guide evolution-informed interventions that support coral reef persistence under climate change.

Norfolk Island's unique corals under triple threat from disease, El Niño and now government-approved dredging

Scientists fear unique corals that fringe Australia’s remote Norfolk Island could disappear because of a triple threat of disease, El Niño and a federal government plan to dredge a neighbouring shipping channel. A failure to manage sediment and pollution washing into bays from cattle farming, cleared land along with wastewater has been blamed for widespread disease and outbreaks of algae over the corals. One expert said most of the island’s corals were likely to be species that have not been formally described by science, and would be unlikely to recover if lost. “We could rapidly lose the coral reefs and we won’t get them back,” said Prof Bill Leggat, a coral expert at the University of Newcastle who has been monitoring the island’s corals and the disease outbreak for five years. Speaking from the island 1,600km north-east of Sydney, Leggat said since March there had been a three-fold increase in diseased corals during of one of the longest-running coral disease events recorded on Australian reefs. Water quality was a key problem, he said, where pollution and sediment would wash into the coral lagoons during heavy rain, promoting disease and algae. “The main issue is the nutrients that increase coral disease...

Co-option of lysosomal machinery shapes the evolution of the intracellular photosymbiosis supporting coral reefs

Corals harbor intracellular algal symbionts in specialized organelles that enable them to build diverse reef ecosystems. Corals and other cnidarians have repeatedly evolved this symbiosis through the ...

Sponges use photosynthesis, boosting productivity of tropical coral reefs

In marine environments, sponges tend to eat other organisms to get their nutrients. But a new study, published by the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics (IBED) researchers in Functional Ecology, demonstrates how sponges may also use photosynthesis, just like plants. This phenomenon can help with the productivity – or amount of energy and food produced – in tropical coral reefs, and perhaps in other ecosystems where sponges are common too.

PhD Fellowship in PFAS Ecotoxicology of Coral Reef Fish in Okinawa, Japan

A fully funded PhD opportunity is available in ecotoxicology to investigate the effects of PFAS pollution on coral reef fish in Okinawa, Japan. The project combines transcriptomics, field ecology, molecular biology, bioinformatics, and environmental risk assessment through collaboration between CNRS, LIEC, and OIST.
