概括
温度显著影响小棕色植物 (Laodelphax striatellus) 的发育和翅膀变形,最佳发育发生在18-28°C之间. 高温和短日可以延迟发育并改变翅膀形态比例,这是气候变化影响分析的关键数据.
科学领域:
- 生态生态学 生态生态学
- 昆虫学 昆虫学是一门学科.
- 气候变化生物学 气候变化生物学
背景情况:
- 温度是一个关键的环境因素,影响ectotherm生命史的特征.
- 小棕色 (Laodelphax striatellus) 是一个重要的农业害虫,其种群动态对环境条件敏感.
研究的目的:
- 调查恒定和变化的温度以及光周期对的发育时间,性别比和Laodelphax striatellus的翅膀变形的影响.
- 为了解气候变化对植物繁殖的影响提供数据.
主要方法:
- 在受控恒温 (18-32°C) 和变化温度下评估了的发育时间,性别比和翅膀变形.
- 实验还结合了不同的光周期 (12-16小时),并考虑了不同的世代.
- 使用统计分析来确定温度,光周期及其对测量特征的相互作用的重要性.
主要成果:
- 的发育时间随着温度从18-28°C升高而缩短,但在更高的温度 (30-32°C) 延迟,增加死亡率.
- 雌性比雄性有更长的发育时间,更短的日长 (12小时) 显著增加了发育时间.
- 翅膀模态受光周期和温度的影响;长的日长有利于长翅形态,而短的日长和低温有利于短翅形态.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

6.6K
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...

3.5K
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;...
