Zebra and quagga mussels entered the Great Lakes in large ships’ ballast water. Now, local boaters and anglers are spreading them into the southern and western US.
Thanks to their high concentrations of phytoplankton, African lakes emit less CO2 than their boreal counterparts, with important consequences for climate modelling.
Layered ice sheets can be vulnerable to fracturing.

Some lakes in the DRC should be thought of as rebellious landscapes having their own social, political and cultural dynamics.
The decreasing ice cover in northern lakes will severely impact the lake ecology as well as winter recreation activities in the northern region.

Lakes in the northern hemisphere are rapidly losing their ice cover due to rising greenhouse gas emissions. The only way to preserve lake ice is to limit GHG emissions and slow down climate change.
Northern map turtles are only one of the freshwater turtle species threatened by human activity.

Increased motorboat activity has resulted in an alarming increase in turtle injuries. Northern map turtles are an at-risk species, and boat collisions threaten their survival.
These insects are basically little machines that convert carbon-rich leaves into nitrogen-rich poo.

As environmental engineers, invasive caterpillars can have remarkable effects on water quality and soil conditions. But from a climate perspective they’re pretty much a nuisance.
Lake Windermere, in England’s Lake District, experiences different mixing processes in its water column.

The growing frequency of climate extremes affected human health and caused wide-scale damages to the ecosystems that people depend upon, including agriculture, fisheries and freshwater.
The Supreme Court recently dealt defeat to Florida in its 20-year legal battle with Georgia over river water. Other interstate water contests loom, but there are no sure winners in these lawsuits.
