概括
来自中国的三种新物种Isodon (Lamiaceae) 使用形态学和遗传学数据被确定. 这些发现扩大了中国已知的伊索登属的多样性.
科学领域:
- 植物学 植物学
- 植物分类学 植物分类学
- 人类遗传学 是一个学科.
背景情况:
- 兰花科家族,特别是伊索登属,在中国是多样化的.
- 以前的分类学处理可能不能完全反映Isodon内部的进化关系.
研究的目的:
- 描述和说明来自中国的三种新物种.
- 用形态和分子数据澄清这些新物种的遗传位置和特异性.
主要方法:
- 植物标本的形态检查.
- 遗传学分析用于重建进化关系.
- 诊断形态特征的比较分析.
主要成果:
- 描述了三种新物种:Isodon attenuatus,Isodon gongshanensis和Isodon sukungii. 这三种新物种分别是:
- 伊索登弱虫在遗传学上与I. villosus相近,但在形态上是不同的.
- 伊索登·贡山尼斯 (Isodon gongshanensis) 代表了一个独特的血统,而伊索登·苏尼 (Isodon sukungii) 基于多个特征而与I. tenuifolius区分开来.

Testing a Claim about Mean: Unknown Population SD
3.4K
A complete procedure of testing a hypothesis about a population mean when the population standard deviation is unknown is explained here.
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
