生殖生物学生殖生物学
野生动物保护野生动物保护
动物行为动物行为

背景情况:

临灭绝的马来亚塔皮尔的现场繁殖对于人口恢复至关重要.
关于生殖生理学的有限研究阻碍了该物种的保护工作.
了解雌性表达是成功养繁殖的关键.

研究的目的:

通过行为观察和 vulva 评分来调查被囚禁的马来亚白的性欲征兆.
识别关键的期行为及其与生理变化的相关性.
提供支持马来亚塔皮尔繁殖计划发展的数据.

主要方法:

通过CCTV录像观测气行为 (发声,flehmen反应,尿液喷,排泄物嗅觉).
根据尺寸和排泄,评估阴道得分 (0-4) .
配对和单独安置的雌性之间的行为比较.
对期周期长度的分析和行为和得分的统计相关性.

主要成果:

发声是最常见的性欲行为 (81%),其次是flehmen响应 (10%).
配对的雌性比不配对的雌性表现出明显更多的发声和尿液喷.
雌激素周期的平均长度为31天,阴道得分和flehmen响应/分泌物嗅觉之间存在正相关性.

结论:

行为和视觉线索可以表明被俘的马来亚白的雌激发.
社会住房 (与雄性配对) 可能会增强雌性行为表达.
这些发现为制定有效的马来亚白养殖和保护策略提供了关键的见解.

Testing a Claim about Mean: Unknown Population SD

Testing a Claim about Mean: Unknown Population SD

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;...
