Freshwater fish suffer from low levels of oxygen in the country’s rivers, while bats are unable to survive the extreme air temperatures.

The shotgun approach, typically thought to be the superior method, may substantially underestimate diversity in environments that have not already been classified, researchers find.

When road deicing salt enters freshwater ecosystems, prey species such as Daphnia pulex can rapidly evolve tolerance to the contaminant, buffering their local food webs from the impacts of salination.

The increasing global demand for potable water needs immediate attention—from researchers and policy makers alike.

A new report estimates that human activities as well as other factors are threatening 20 percent of all invertebrate species, including corals and freshwater snails.

A unique resource for studying environmental impacts on freshwater systems is threatened by federal funding cuts.
