概括

圣劳伦斯河中的鱼海摄入了大量的塑料污染,随着小的化,碎片减少. 这突显了人类废物对野生动物的风险.

科学领域:

环境科学环境科学
生态生态学生态生态学
野生动物生物学野生动物生物学

背景情况:

人为垃圾,特别是塑料,是全球日益严重的环境问题.
圣劳伦斯河生态系统具有生物多样性,但面临着多种环境压力因素.
野生动物暴露于人为废物,特别是塑料污染,尚不清楚.

研究的目的:

为了评估成年美国鱼海 (Larus smithsonianus) 在繁殖季节的塑料碎片摄入和饮食.
为了研究海在繁殖周期期间食习惯和碎片暴露的变化.
了解人为资源对海饮食和碎片暴露的影响.

主要方法:

在从北克贝尔查斯岛收集的海颗粒中分析碎片含量 (发生,数量,质量).
在整个繁殖季节对成年美国鱼海的饮食分析.
化期和养期之间的杂物摄入和饮食多样性的比较.

主要成果:

大约50%的分析的海颗粒含有碎片,其中80%的碎片是塑料.
碎片的发生,数量和颗粒中的质量从化到早期的养显著下降.
在早期的养过程中,的饮食是最不多样化的,依赖于陆地和可能的人为食物来源.

结论:

城市化繁殖的鱼海表现出大量的塑料摄入,对成年鸟类和它们的小鸟构成风险.
在养期间,食行为的变化可能会影响碎片暴露水平.
调查结果强调需要加强废物管理策略,以减轻塑料污染对圣劳伦斯河野生动物的影响.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Levels of Organization

Levels of Organization

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:
The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules...
