Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a University of Otago study showing they are still harmful to fish.

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean.

As climate change warms the planet and droughts are anticipated to become more frequent and extreme, a new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers - creating major challenges for aquatic life, ecosystems, and society.

For several months in 2023, global sea surface temperatures reached record-high levels, fueled by decades of human-caused climate warming and a recent boost from the natural climate phenomenon El Niño. 

Published in Science Advances, the study explores the intricate interplay between climate change, land use change, and their impact on pollinator biodiversity, ultimately revealing significant implications for global crop pollination.

Dynamic and changing Arctic Ocean conditions likely caused three major mortality events in the eastern North Pacific gray whale population since the 1980s, a new study has found.

Lack of rainfall is not the only measure of drought. 

Researchers have analyzed samples collected from the sea surface of the Catalan coast and the Guadalquivir River. 

In identifying and dating coral remains in drill cores taken from Belize reefs, a team of experts from Goethe University Frankfurt and partners from Germany, the USA and Canada has shown the importance of specific types of coral for reef-building during the current Holocene geological epoch, dating back some 12,000 years.

Insect populations are widely influenced by weather anomalies, with decreasing numbers observed during unfavorable conditions and a spike in normal periods, according to a new study.
