概括
过冬的纸 (Polistes dominula) 通过聚合不会节省能源. 与预期相反,聚合物显示出更高的活动,这表明其他因素推动了这种过冬行为.
科学领域:
- 生态生态学 生态生态学
- 动物行为 动物行为
- 生理学 生理学 生理学
背景情况:
- 温带地区的昆虫,如纸 (Polistes dominula),在受保护的地方过冬.
- 过冬需要大量的能量储备,昆虫聚集被认为可以降低能源成本和干燥压力.
- 在单独的昆虫和集体中的昆虫之间,新陈代谢速率可能会有所不同.
研究的目的:
- 为了研究过冬的纸黄蜂基因 (雌性) 的新陈代谢率.
- 为了确定聚合是否会在过冬期间降低能源消耗.
- 探索纸黄蜂的新陈代谢,活动和聚合之间的关系.
主要方法:
- 在三种不同的温度 (4,8,12°C) 下,单独和集体研究了纸黄蜂的基因.
- 碳二氧化物 (CO2) 产量,即代谢率的指标,在单个黄蜂和群体中进行了测量.
- 观察和记录了与代谢测量同时进行的运动运动活动.
主要成果:
- 代谢率随着环境温度的指数增长,单身黄蜂和聚类黄蜂的代谢率呈指数增长.
- 在单个纸黄蜂和聚合物中的纸黄蜂之间没有发现代谢率的显著差异.
- 与单独个体相比,聚合体表现出更高的活动水平.
结论:
- 节能似乎不是过冬纸黄蜂遗传中的聚合行为的主要驱动因素.
- 聚合物中的较高活动水平表明,除了节能之外的其他因素也会影响这种行为.
- 需要进一步的研究,以了解纸黄蜂过冬聚合物的充分适应意义.

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

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.

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
