Fish Diet Heats Up Marine Biodiversity Hotspot

Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change.

Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change.

A new study shows plankton-eating coral reef fishes (planktivores) are far more diverse than others in the Indo-Australian Archipelago, a global marine biodiversity hotspot.

The findings highlight, for the first time, a unique link between the diet and distribution of species across the marine realm.

“The archipelago is one of the most complex and dynamic geological regions in the tropics,” said lead author Dr Ale Siqueira from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU). “And its fishes underpin its status as a biodiversity hotspot.”
