Salinated water in abandoned mine pit lake favors invasive species dominance.
The scientists studied a lake in Poland that used to be a sulphur mine. They wanted to see how the environment affected the bugs living there. They found that the salty water made it hard for native bugs to survive, so non-native mussels took over. Bugs like mayflies and damselflies were rare, but chironomids and zebra mussels were common. The salty water changed the bug population in the lake.
