Man-made reservoirs are contributing to the spread of non-native species in Wisconsin lakes, a study has found.
In a comparison of natural lakes and reservoirs created by damming rivers, the reservoirs were up to 300 times more likely than lakes to harbor invasive aquatic species, according to the study published in September in the journal Frontiers in Ecology and the Environment.
