海洋污染影响了像风暴这样的迁徙海鸟,它们从饮食中积累. 这项研究揭示了含量因物种,地点和猎物而异,突出了风暴作为海洋污染的生物指标.
科学领域:
- 海洋生物学 海洋生物学
- 环境毒理学环境毒理学
- 鸟类生态学 鸟类生态学
背景情况:
- 海洋因工业生产和消费者行为而受到越来越多的污染,影响全球野生动物.
- 迁徙的海鸟,如风暴,在不同地区食,可能从不同地区积累.
- 了解海鸟中的污染物负载对于评估海洋污染影响至关重要.
研究的目的:
- 为了比较各种繁殖和非繁殖地点的七种风暴的含量.
- 调查污染如何与物种分布,迁徙模式和热量位置有关.

24.5K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:27The Periodic Table and Organismal Elements
17.4K
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.
