根据本周《通讯-生物学》发表的一篇论文Artificial light during the polar night disrupts Arctic fish and zooplankton behaviour down to 200 m depth,北极海底200米处的海洋生物会受到船只上人造光的干扰。这项发现意味着在极夜期间,人造光会影响种群调查,进而对可持续管理工作产生影响。
摘要:For organisms that remain active in one of the last undisturbed and pristine dark environments on the planet—the Arctic Polar Night—the moon, stars and aurora borealis may provide important cues to guide distribution and behaviours, including predator-prey interactions. With a changing climate and increased human activities in the Arctic, such natural light sources will in many places be masked by the much stronger illumination from artificial light. Here we show that normal working-light from a ship may disrupt fish and zooplankton behaviour down to at least 200 m depth across an area of >0.125 km2 around the ship. Both the quantitative and qualitative nature of the disturbance differed between the examined regions. We conclude that biological surveys in the dark from illuminated ships may introduce biases on biological sampling, bioacoustic surveys, and possibly stock assessments of commercial and non-commercial species.
