- 野生动物管理 野生动物管理
背景情况:
- 非洲热带地区面临生态系统变化和生物多样性丧失,需要有效的监测工具.
- 大猿是有魅力的巨型动物,面临着保护挑战.
- 了解共同发生的模式可以揭示生态系统健康指标.
研究的目的:
- 评估大猿的丰富性是否可以作为哺乳动物多样性和社区指标的代理.
- 评估子检测率与其他中大型哺乳动物群体之间的关系.
- 通过确定可靠的指标物种,为保护战略提供信息.
主要方法:
- 利用了来自12个撒哈拉以南非洲国家的22个研究站点的摄像头陷数据 (2010-2016).
- 分析了约35万张摄像机陷视频,以估计哺乳动物社区指标 (物种丰富,多样性,平均质量).
- 采用贝叶斯回归模型,将猿类检测率 (作为丰度代理) 与哺乳动物社区指标联系起来,控制保护状态和人类足迹.
主要成果:

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

3.9K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

01:20Evolutionary Psychology
214
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...
