Extinctions linked to new assemblages of species — ScienceDaily

Scientists have found that as the world undergoes profound environmental change, identifying and protecting ‘novel’ communities of species can help prevent extinctions within vulnerable ecosystems.

Professor John Pandolfi and Dr Timothy Staples from the ARC Centre of Excellence for Coral Reef Studies at The University of Queensland (CoralCoE at UQ) are the lead authors of a new study in Science that looked at how combinations of plankton species changed across the world’s marine ecosystems in the past 66 million years. From this, their team developed a world first method to detect ‘novel’ communities of species across all ecosystems.

“A novel ecological community is one with combinations of species that are different to any past observations from that site,” Prof Pandolfi said. “These different species combinations can be due to new species arriving in the community, existing species leaving, or species becoming rarer or more common.”

“We found that when novel
