背景情况:
- 塑料污染,特别是微塑料 (MP) 和纳米塑料 (NP),对海洋生态系统构成越来越大的威胁.
- 低度MP和NP对珊瑚的生理影响尚不清楚.
- 珊瑚礁面临着气候变化和污染带来的越来越大的压力.
研究的目的:
- 研究MP和NP对两种珊瑚物种生理学的慢性影响.
- 评估对共生体健康,光合作用,呼吸和能量储备的影响.
- 为了确定特定物种对塑料暴露的反应.
主要方法:

- 评估共生体生理学和光合作用性能.
- 测量呼吸和能量储备含量 (脂质,蛋白质,碳水化合物).
主要成果:
- 杆虫 (Stylophora pistillata) 显示出对MPs的高度敏感性,经历了白化,光合作用减少和能量储备耗尽.

Bioremediation
22.6K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Diversity of Protists III
1.3K
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Green Algae
954
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
