Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
The lives of one in ten of Earth’s species are connected to lakes and their tributaries.
For temperature-sensitive animals, the dense, leafy canopy of willow trees may make them the lesser of two evils in a warming climate.
Earth's floating solar power capacity has grown one-hundredfold in the last five years.
We found that signal crayfish traps tend to catch larger males, letting the bulk of the population go free.
Microplastics could pose a threat to the sustenance of aquatic biodiversity when ingested by animals.
The ghosts of our industrial and agricultural past continue to haunt freshwater ecosystems today.
Twenty of these freshwater fish species have a 50% or greater probability of extinction within the next 20 years.
Fish need to cross roads too. But the tunnels built to channel rivers under roads and railways can block their migrations.
The discovery that such a common animal can rapidly produce vast numbers of nanoplastics is particularly worrying.
The review examined hundreds of studies and concluded the lower Murray should remain a freshwater ecosystem, or severe environmental and economic damage will result.
The largest study of insect declines to date gives us the best indication of how species all over the world are faring.
A new report on New Zealand’s lakes and rivers confirms that many freshwater ecosystems are in decline and warns that climate change will exacerbate existing threats.
Coming to a river catchment near you: a rodent crack team ready to reduce flooding and boost biodiversity.
Hundreds of thousands of lakes, rivers and streams in the Arctic exist only because of the permafrost that lies beneath them. The warming Arctic threatens to change that.
Lakes are the final resting place for many of the Earth’s plants – and these organic graveyards are about to get a whole lot busier.
Scientists are left with two conclusions. Either Nessie is an eel, or she never existed at all.
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.
Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
The introduction and spread of invasive freshwater crayfish into Africa threatens the continent’s freshwater biodiversity.
