概括
熊蜂在像飞行这样的防御行为中表现出习惯和不习惯. 这表明它们的防御策略具有响应特定的可塑性,适应不断变化的刺激.
科学领域:
- 动物行为 动物行为
- 神经伦理学 神经伦理学
- 昆虫的认知能力
背景情况:
- 习惯和脱习是影响动物对刺激反应的关键适应过程.
- 这些过程包括对重复的,无关紧要的刺激的反应减少 (习惯) 和对新兴刺激的反应的更新 (不习惯).
研究的目的:
- 研究大黄蜂 (Bombus terrestris) 防御反应的习惯和脱习.
- 为了确定这些适应过程是否在自然环境中是响应特异性的.
主要方法:
- 自由地寻找食物的熊蜂被暴露在重复的头顶迫在眉的刺激中.
- 引入了独特的振动来测试失习.
- 监测了三种防御反应:飞行,干扰,抬腿反应和惊.
主要成果:
- 飞行概率表现出强大的习惯和脱习.
- 在整个实验中,干扰腿提升反应始终保持一致的频率.
- 启动响应最初增加,然后下降,随着飞行恢复.
结论:
- 熊蜂在自由飞行的范式中表现出明显的防御性飞行反应的习惯和失习.
- 研究结果支持动物防御机制中存在响应特异性的可塑性.
- 区分多种防御反应是了解习惯/失习机制和精心调整的防御策略的关键.

01:06Fixed 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.
02:39Predator-Prey Interactions
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.Although predation is commonly associated with carnivory, for...
