Spawning Sea Lampreys Amplify Streambed Diversity, Say UMaine Scientists
Sea lampreys impact rivers for months, perhaps years, due to their disturbance of streambeds when they spawn, say University of Maine researchers. Robert Hogg, a master’s graduate who participated in the study, writes in a journal article that sea lampreys (Petromyzon marinus) are ecosystem engineers. The physical disturbance caused by their “nest-building activity was significant […]
