- 环境毒理学环境毒理学
- 水生生态学 水生生态学
背景情况:
- 人为噪音是一种普遍存在的全球污染物.
- 噪音对鱼类早期生命阶段的影响仍然不太清楚.
- 常见的 (Pomatoschistus microps) 展现出独特的父亲关怀,使其成为一个合适的模型.
研究的目的:
- 调查连续和间歇的低频宽带噪声对普通的早期生命阶段的影响.
- 评估噪音对子类食人,幼大小和后代发育的影响.
- 为了确定暴露于噪音是否会影响鱼幼虫发育中的与健康相关的特征.
主要方法:
- 控制的实验室实验使普通鸟子暴露在连续或间歇的噪音中.
- 监测父亲男性的子女食人率.
- 量化繁殖群的大小 (蛋数) 和繁殖群所覆盖的面积.
- 测量幼虫发育速度,身体长度和化时的黄囊大小.
主要成果:
- 噪音暴露没有影响子女食人行为,这表明父亲继续照顾孩子.
- 与对照组相比,持续的噪音暴露导致了较小的繁殖区和较少的卵数.

00:55Parental Care
11.7K
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

01:11Testing a Claim about Mean: Known Population SD
2.7K
A complete procedure of testing the hypothesis about a population mean is explained here.
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...

01:06Fixed Action Patterns
16.0K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
