      夜間“光污染”可能導致植物減產

      時間 2018-01-10     

      ????瑞士伯爾尼大學生態學家埃瓦·克諾普表示,目前夜間人造光源以年均6%的速度在增長,這顯然已經對動植物產生了一定的影響。

      ????花朵長成果實的過程中,最重要的因素就是昆蟲授粉。克諾普團隊找了14處不同的草地,其中在7處此前從未布置過人工光源的草地上,設置了一種在歐洲很常見、黃昏時可以自動亮起的LED路燈;作為參照的還有另外七塊沒有布置人工光源的草地。研究人員發現,在有燈光的草地,夜間傳粉者造訪的次數銳減了62%,后果就是,植物結果數量也相應下降。

      ????此外,研究人員還對卷心菜進行了監測,發現在明亮草地上的植物減產了 13%。克諾普表示,盡管這些植物在白天也有很多傳粉者造訪,但仍無法彌補缺少夜間授粉所造成的產量損失。
