概括
在类动物中,单向的顺从呼叫具有双重功能,类似于. 然而,服从并没有稳定群体动态,它的频率与相比,与主导风格相反.
科学领域:
- 灵长类动物的沟通方式
- 动物行为 动物行为
- 社会动态 社会动态
背景情况:
- 正式化的信号对于动物主导关系至关重要.
- 在像这样的灵长类动物中,服从信号具有双重功能 (冲突撤回,和平服从),随着统治风格的变化而变化.
- 的统治风格和屈服信号之间的关系仍然未被探索.
研究的目的:
- 为了研究两种毛动物中主导风格和单向提交信号的使用之间的关系.
- 为了确定信号服从是否稳定了在群体层面的社会关系.
- 为了比较的信号模式与的信号模式.
主要方法:
- 在环尾 (Lemur catta) 和Verreaux's sifakas (Propithecus verreauxi) 的二中观察社会相互作用.
- 分析了75个Verreaux的Sifakas双和118个环尾双.
- 两种不同主导风格的物种之间的呼叫使用和社会关系稳定性的比较.
主要成果:
- 两种鼠种都使用双重功能的单向顺从呼叫,这表明灵长类动物声学交流中的融合进化.
- 在任何一种物种中,信号服从都不能明显地稳定群体层面的社会关系.
- 专制的环尾比Verreaux的sifaka更频繁地发生了服从,与的模式形成鲜明对比.
结论:
- 虫表现出在顺从呼叫的双重功能中的融合进化,独立于.
- 在这些类动物中,信号服从似乎不是稳定群体社会关系的机制.
- 的社会特征和统治风格的共同进化与相比,显示出相反的模式.

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
