研究表明:“灰熊不吃鲑鱼改吃接骨木果的行为不仅破坏了滋养陆地生态系统的生态链,还促成了鲑鱼的高死亡率。”
On average, red elderberries are said to be ripening two and a half days earlier every decade.
据称,平均每十年,红接骨木果成熟的时间会提前两天半。
If the pattern continues, they will regularly overlap with the salmon by 2070.
如果再这样下去,到2070年,鲑鱼和接骨木果的成熟期将会定期重合。
The study was published in the Proceedings of the National Academy of Sciences.
这项研究成果已在《美国科学院学报》上发表。
