概括

紫外线B (UVB) 辐射会对水生无脊椎动物造成伤害,如. 早期的紫外线暴露可能会造成持久的损害,影响发展,行为和生存,影响水生生态系统.

科学领域:

环境科学环境科学
海洋生物学海洋生物学
生态毒理学生态毒理学

背景情况:

紫外线B (UVB) 辐射的增加对水生生物构成威胁.
胚胎和幼虫往往缺乏针对UVB的发达的保护机制.
麦克罗布拉基奥尔弗西 (Macrobrachium olfersii) 是一种重要的十足动物,生活在易受UVB辐射的浅水中.

研究的目的:

为了研究UVB辐射对Macrobrachium olfersii幼虫的影响.
为了比较幼虫对胚胎和化后阶段UVB的反应.
为了确定紫外线引起的胚胎损伤是否持续到幼虫发育.

主要方法:

将M. olfersii的胚胎和幼虫暴露在UVB辐射中.
评估幼虫的身体长度,眼睛指数和与线粒相关的蛋白质.
量化DNA损伤,细胞增殖,细胞亡和行为变化 (迁移,透明度).

主要成果:

紫外线暴露影响了幼虫的体长,眼睛指数和胚胎和幼虫阶段的线粒细胞蛋白.
后期暴露导致更严重的DNA损伤,改变细胞增殖和亡.
两种暴露阶段都减少了幼虫迁移;细胞透明度只有在较晚的暴露时才降低.

结论:

紫外线 (UVB) 辐射对M. olfersii的发育有延续效应.
早期的紫外线暴露可能会诱导适应,而晚期的暴露会导致生理障碍.
这些损害可以减少捕食者逃避,生存和繁殖的成功,影响水生食物网.

Mutations

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
