New Zealand’s economically driven approach to ecological decline risks entrenching environmental problems rather than solving them.
Almost 100 years ago, the foundations to preserve the Boundary Waters in Minnesota for recreation were put in place. Now residents are debating whether to allow a mine in its headwaters.
Freshwater is one of the most threatened resources on Earth. Dragonflies can tell us what we need to know about the state of this precious resource.
Buried beneath kilometres-thick slabs of ice are rivers and huge lakes - some of which are teeming with microbes that thrive in a world without light or oxygen.
Conservation methods for gravel-bed rivers – which are ecological hotspots in the western U.S. – need to improve in order to deal with the effects of climate change.
Freshwater fish are declining everywhere, in part thanks to dam-building. But we can have both.
Toxic algal blooms were unheard of in Australia’s major waterways before 1991. Now the Murray River has been struck by four major events in less than a decade, with more likely in the future.
Many pet fish end up in ponds, fountains and waterways. But before ditching your goldfish in the park, stop and think about the viruses you could also be releasing.

Rising carbon dioxide levels are making plants grow faster, sucking up more water and reducing river flows in many agriculturally important areas of Australia, according to new research.
Around the world, waterbugs are the most widely-used indicator of environmental health and pollution of rivers, lakes and wetlands.
Unless something is done to curb erosion, Ghana’s coast could soon whither away.
Successive plans to curb the sediments, nutrients and pesticides flowing into the waters around the Great Barrier Reef have fallen short, leaving the corals that call the reef home highly vulnerable.
Freshwater ecosystems such as rivers, lakes and wetlands are precious. They contain several-times more vertebrate species per unit area than land and ocean environments, and they are more degraded. Protected…
A new river flow forecast model should improve the accuracy and reliability of forecasting extreme weather. The model, developed…
Rivers and streams release carbon dioxide at a rate five times greater than the world’s lakes and reservoirs combined. The…
