Canadian ecologists have discovered that antidepressants and opioids accumulate in the tissues of small river fish living downstream from wastewater treatment plants. The study revealed gender differences in toxin accumulation and proposed a new analytical method to assess the impact of pharmaceutical pollution on aquatic ecosystems.
A study has shown that beaver dams enable bodies of water to store nearly 200 times more carbon than ordinary streams, thereby reducing carbon emissions into the atmosphere and oceans. Beavers alter the biogeochemistry of rivers, transforming them into highly effective carbon reservoirs.
A new study has found that heat waves in U.S. rivers are intensifying four times faster than in the atmosphere and last nearly twice as long, posing a serious threat to aquatic ecosystems and water quality.
