概括
稀土元素 (REEs) 是全球野生动物中发现的新兴污染物. 本次审查强调了知识缺口,特别是在陆地生态系统,并呼吁对环境中的REEs进行标准化监测.
科学领域:
- 环境科学 环境科学
- 生态毒理学 生态毒理学
- 野生动物生物学 野生动物生物学
背景情况:
- 稀土元素 (REEs) 在技术和工业中越来越多地使用,导致它们作为环境污染物的出现.
- 它们不断扩大的存在需要了解它们对各种生态系统中自由活动的野生动物的影响.
研究的目的:
- 系统地审查和综合有关野生动物中REE度的当前知识.
- 确定REE生态毒理学中的地理,分类学和方法学研究差距.
主要方法:
- 从Scopus和Web of Science中选择的1976年至2025年间发表的95项同行评审研究的系统综述.
- 基于PRISMA 2020指导方针的研究分析,涵盖地理分布,分类覆盖范围,营养水平,组织类型和分析方法.
- 评估数据报告和方法一致性,以评估跨研究可比性.
主要成果:
- 大多数研究都集中在欧洲的水生生物上,在REE储量丰富的国家中,REE储量不足.
- 在较低的热带水位和盆地物种中观察到较高的REE度,支持热带稀释.
- 肝脏,脏和甲在脊椎动物中显示出最高的REE度;像羽毛和便这样的非侵入性样本显示出生物监测潜力.
- 方法上的不一致性阻碍了可比性,对于陆地生态系统和暴露于肥料的农业地区存在重大知识差距.
结论:
- 目前对野生动物的REEs的研究在地理和分类学上存在偏见,方法上的不一致性限制了全面的理解.
- 需要更广泛的分类学和地理覆盖,标准化的方法和将REE纳入长期环境监测计划.
- 了解REEs的生态和毒理影响至关重要,因为它们的持久性和作为标记物和污染物的双重作用.

02:31Habitat Fragmentation
20.9K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

01:27The Periodic Table and Organismal Elements
22.1K
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.
