- 野生动物毒理学
- 环境科学环境科学
背景情况:
- 摄入塑料对野生动物构成风险,但对生理影响的了解很少.
- 当前的研究往往依赖于有限的机会性采样.
- 由于它们的食习惯,海鸟很容易受到塑料污染的影响.
研究的目的:

7.9K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
