Freshwater fish are suffering as drought becomes more common and severe. Whether they survive will depend on how governments manage rivers and lakes, and on taking action against climate change.
It's cheaper to prevent biological invasions than to react after they happen. But it's hard to detect invaders while there are still just a few of them. Knowing when and where to look can help.
Populations of freshwater species are in a state of deep decline. But we know why and we can reverse the trend.
Roughly 10,000 tons of plastic enter the Great Lakes every year, and scientists want to know where it ends up. There are some parallels to ocean plastics, but also important differences.
A recent study shows plankton that have adapted to road salt have disrupted circadian rhythms. This finding suggests that environmental pollutants could also affect human circadian clocks.
With frigid temperatures and snow in the forecast, slippery roads can't be far behind. Salt keeps roads safe, but it's harmful to aquatic environments.
Canadians love to paddle on them and camp beside them, but our boreal lakes offer more than just peace and beauty. They could provide clues to how life on Earth began.
What do you do with a giant pit mine once it closes? One option for the Hazelwood mine is creating a recreational lake – but there are economic and environmental issues to consider.
Floods are often seen as a force of destruction. But as river ecologists, we find it hard not to rejoice at the flooding.
Scientists are pioneering a new way of monitoring water species, using techniques more familiar to fans of crime scene TV shows.
Lakes contain most of the fresh water on Earth's surface. Recent research at Lake Tahoe in the Sierra Nevada mountains shows that climate change could alter lake chemistry, threatening these sources.
Freshwater covers only 0.5% of the Earth's surface but is home to 10% of the world's lifeforms.
Invasive species cause some $120 billion in damages across North America yearly -- and that's just direct costs. A study of one species in one Wisconsin lake indicates the real toll is much higher.
A score of new fish species discovered recently in northern Australia remind us how little we know about our country.
Plans to dam Lake Baikal's most important tributary could kick off an international dispute.
Potentially dangerous plastics and microplastic particles are contaminating subalpine lakes at a rate similar to levels found…
Blue Lake, one of the largest lakes on North Stradbroke Island, southeast of Brisbane has been relatively unaffected by the…
Blue Lake on North Stradbroke Island in Queensland has remained relatively untouched by climate change, a study has found…
