James Cook University researchers found that nearly 40% of 155 anglers never fished illegally in a simulated Great Barrier Reef zone, despite cash rewards. The authors say managers can publicize that share to build a compliance norm, citing tipping-point work from other experiments.

Researchers from Exeter, ETH Zurich and James Cook University estimate that fire-driven ozone cuts Amazon carbon uptake by about 24% of the fires' emissions. They warn the strong El Niño now forming could push that hidden loss up again.

James Cook University found Cairns' Trinity Inlet seagrass regrew to its pre-flood area after a 98% loss, with a different mix of fish species. A recovery measured in hectares alone would overstate how far the meadow's ecosystem has come back.

Researchers writing in Nature Human Behaviour estimate a median pre-colonial Indigenous population of 2.22 million and 2.06 million excess deaths by 1861, built from genetics and environmental modelling instead of colonial head counts.

A Charles Darwin University risk assessment built with eight First Nations ranger groups located illegal fishing in waters that vessel tracking data cannot see, which is exactly where non-compliance would hide.

A 78-day playback experiment on Great Barrier Reef spiny chromis separates the window that stunted growth from the one that broke escape responses, which is what makes vessel traffic a lever managers can pull.
