MAISRC researchers Przemek Bajer, Justine Koch, and Peter Sorensen recently published a new paper, Biological invasion by a benthivorous fish reduced the cover and species richness of aquatic plants in most lakes of a large North American ecoregion. The paper discusses new reserach that is showing that invasive common carp are more damaging to biodiversity than human development. They found that when common carp were prolific, plant cover was reduced to less than 10% and species biodiversity was halved. By teasing out the impacts of other human-caused stressors, this research also revealed that carp had a greater impact on aquatic plant biodiversity than human watershed development did.
