概括

探索速度较慢的红结在群体中更快地找到食物,从社会线索中受益. 快速的探险者更快地独自一人,表现出个性影响社会食成功.

科学领域:

行为生态学行为生态学
动物行为动物行为

背景情况:

集体食带来竞争,但也提供了生存的社会信息效益.
个性特征会影响个人的食策略,比如害羞的鸟在食.
在社会背景下,人格和食策略之间的相互作用是不充分研究的.

研究的目的:

为了研究探索性个性,群体规模和在红结中寻找食物的成功之间的关系.
了解不同的人格类型如何在不同的群体组成中适应它们的食策略.

主要方法:

实验是在受控群体大小 (1-4只鸟) 中对野生捕获的红结进行的.
获取食物的成功是通过个体找到食物斑块的速度来衡量的.
探索性个性被评估,以将鸟类归类为更快或更慢的探索者.

主要成果:

单独来说,更快的探险者比较慢的探险者更快地发现了食物斑块.
在群体中,较慢探索的鸟类与较快探索的鸟类相比,其食速度增加.
较慢的探险者似乎更容易对社会线索做出反应,提高了他们在群体中寻找食物的效率.

结论:

探索速度较慢的个体从社会食中获得了显著的好处,改善了他们的食物发现率.
人格特质对寻找食物的策略和在社会动态中取得成功具有重要影响.
不同的人格和食策略可以在社会群体内共存,每一个都有独特的成本和收益.

Fixed Action Patterns

Fixed Action Patterns

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.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
