概括
随着COVID-19的流行,储存行为发生了变化,但生殖欲望并没有发生变化,与生命史理论预测一致,用于在不确定的环境中快速策略.
科学领域:
- 进化心理学 进化心理学
- 行为生态学 行为生态学
- 人类的决策能力.
背景情况:
- 生命史理论 (LHT) 认为,生物根据环境条件平衡繁殖和自我维持.
- 危险或不可靠的环境有利于"快速"的生命史策略,优先考虑短期收益.
- COVID-19大流行造成了前所未有的全球生存威胁增加,提供了一个独特的背景来研究与LHT相关的决策.
研究的目的:
- 调查有关COVID-19流行病的担忧是否影响了与繁殖和资源储存相关的决策.
- 检查COVID-19担忧在生命史策略与这些决定之间的关系中的调解作用.
主要方法:
- 一项在线心理测量研究与274名参与者进行.
- 收集的数据包括生活史策略的措施,COVID-19的担忧,对孩子的渴望和储存行为.
- 进行了统计调解分析,以测试研究假设.
主要成果:
- 由于COVID-19的担忧,生命史策略与储存食品和家庭杂货之间的联系显著受到影响.
- 然而,COVID-19的担忧并没有调解生命史策略与生孩子或生更多孩子的愿望之间的关系.
- 这些对比的发现表明,人们对所感知的环境威胁的反应不同.
结论:
- 这项研究表明,高存在威胁 (COVID-19) 可以显著影响与快速生命史策略一致的资源获取行为 (库存).
- 缺乏对生殖决策的调解表明,这些决策可能对即时的环境变化不那么敏感,或需要不同的触发因素.
- 这些发现突出了环境不确定性对人类决策的影响在不同生命历史领域的微妙方式.

00:51Energy Budgets
9.7K
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...

01:24Metabolic States of the Body: Fasting and Starvation
1.8K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

02:39Predator-Prey Interactions
19.2K
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.

01:21Causality in Epidemiology
872
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
