概括

父母通过吃生病的来防止疾病传播来实践子女食人主义. 这种行为还允许它们重新利用能量生产更多的蛋,使殖民地受益.

科学领域:

进化生物学进化生物学
动物行为动物行为
生态生态学生态生态学

背景情况:

亲属食人主义,父母食用他们的后代,在物种中很常见.
病原体在子女食人主义中的作用尚不清楚.
现有的理论表明食人主义可能是适应资源再投资的.

研究的目的:

为了研究病原体对子食人行为的影响.
探索食用感染后代的适应性益处.

主要方法:

单独发现女王的观察.
分析幼虫的健康状况和巢内的疾病传播.
评估女王的存活率和随后的卵产量.

主要成果:

在它们传播感染之前,女王会选择性地吞食生病的幼虫.
这种行为有效地阻止了巢中致命的感染.
患病幼虫的食人行为并没有对女王的生存产生负面影响,而且增加了卵子的产量.

结论:

附属食人主义可以作为殖民地疾病控制机制.
消费感染后代通过预防流行病和增强生殖提供了适应优势.
这项研究突出了一个关于子女食人主义演变的新解释.

Bacterial Signaling

Bacterial Signaling

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
