Due to temperature change, oceans are heating up and corals are continuing to bleach which is causing Australia’s Great Barrier Reef’s fish communities to fade and lose their colour, in step with a replacement study.
This study has been published in Global Change Biology. Dr Hemingson at Captain Cook University, Queensland, Australia led this newly published study.
This recently published study has monitored the changes seen within the fish communities’ colouration further as their living environment.
According to researchers, the fish communities’ colour diversity is linked to the local environment’s composition.
The study also revealed that areas that had a better concentration of structurally complex corals housed species of fish with more bright and diverse colourations.
Due to global environmental change, the connection between the colouration of the Nice Barrier Reef’s fish communities and therefore the environment is being impacted. Links are found by researchers between fish and corals that are constantly losing their natural colour.
The green and yellow fish population has dropped at a gentle pace by around three quarters over the past 27 years. After the 1998 global coral bleaching event, fish communities’ colouration fell significantly.
According to recent reports, bleaching has again occurred within the Great coral reef with higher-than-average ocean temperatures is being a relentless threat to them. Surveillance flights have revealed that minor to severe bleaching has occurred thanks to the heat.
