![]() When a lake is in the latter state, algae use up all the nutrients in the water and block sunlight, preventing the growth of aquatic vegetation that would aid ecosystem recovery. They are either healthy – with clear water with an abundance of vegetation, or degraded – with cloudy water dominated by algae. Shallow lakes naturally exist in one of two alternative stable states. The paper also provides guidance on how to manage bodies of water. UK public's knowledge of nature's planet-saving power proves cloudy, according to new research.The study found that invasive fish such as Asian silver carp, Hypophthalmichthys molitrix, and crustaceans such as American signal crayfish, Pacifastacus leniusculus, significantly reduced the abundance of other important organisms in lakes and degrade water quality. Scientists say certain invasive, non-native species can rapidly disrupt the environment of lakes – contaminating water for drinking, aquaculture and recreation.Ĭlimate change and human activity are causing these animals to spread rapidly across the world and researchers suggest that certain invasive species can push lake ecosystems beyond a critical tipping point, causing a sudden shift from healthy to degraded conditions that is difficult to reverse. Crayfish and carp are among the invasive species pushing lakes towards ecosystem collapse, researchers have found. ![]()
