概括

夜间的人工光 (ALAN) 重塑了沿海遗传学. 亚兰和航运对东京湾同类动物的物种分布和特征产生影响.

科学领域:

海洋生物学海洋生物学
生态生态学生态生态学
遗传学是一个遗传学.

背景情况:

夜间人工照明 (ALAN) 正在对沿海生态系统产生越来越大的城市影响.
它对遗传结构和物种相互作用的影响尚不清楚.

研究的目的:

研究ALAN对两个密切相关的同类动物物种的遗传结构和息地分离的影响.
识别预测物种发生的环境因素,包括ALAN.

主要方法:

在东京湾的ALAN梯度上对同类动物的基因组和线粒体DNA分析.
贝叶斯对28年环境数据 (光强度,盐度,植被) 的建模.
实验室测试以评估慢性ALAN暴露对同类动物生长和活动的影响.

主要成果:

在内湾 (L. laticarpa) 和外湾 (L. furcata) 种群之间观察到明显的遗传分离.
夜间光线强度,盐度和植被覆盖是物种分布的关键预测因素.
暴露于ALAN会降低L.furcata的生长和活动,但不会降低L.laticarpa的生长和活动.

结论:

阿兰和海上活动共同影响沿海同类动物的遗传连接和息地分离.
像ALAN这样的人类干扰可以在密切相关的物种之间推动生态分歧.
研究结果提供了关于城市化如何影响海洋生物多样性和适应性的见解.

Diversity of Protists III

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,...

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.
