概括

夜间人工照明 (ALAN) 破坏了岩石鱼的行为,损害了它们寻找黑暗,安全环境的能力. 接触ALAN会使鱼类失去定位,使他们不太可能选择喜欢的黑暗区域.

科学领域:

海洋生物学海洋生物学
行为生态学行为生态学
环境科学环境科学

背景情况:

人工夜间照明 (ALAN) 破坏了自然的日光周期.
改变的光周期会影响野生动物的行为和决策.
潮间物种在人类照明的环境中面临着独特的挑战.

研究的目的:

为了研究ALAN对潮间岩石鱼 (Girella laevisifrons) 的决策过程的影响.
为了确定先前接触ALAN是否会影响Y迷宫实验中的定向游泳行为.
评估ALAN对岩石鱼偏好黑暗与照明环境的影响.

主要方法:

使用Y迷宫装置测试岩石鱼的行为.
鱼类暴露在自然昼夜周期或ALAN条件下一周.
量化了参观和在迷宫的黑暗,明亮和非决策区域度过的时间.

主要成果:

在自然光线条件下,岩鱼更喜欢黑色的手臂.
暴露于ALAN的鱼在非决策区域花费了更多时间.
艾伦暴露影响了岩石鱼的行为以大小依赖的方式,降低了它们选择黑暗区域的能力.

结论:

之前在夜间接触人工光线可能会使岩石鱼失去方向.
艾伦暴露似乎减少了岩石鱼选择黑暗,可能更安全的条件的能力.
这些发现突出了因光污染导致的潮间物种潜在的行为障碍.

Testing a Claim about Mean: Known Population SD

Testing a Claim about Mean: Known Population SD

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...
