阿尔卑斯山和比利牛斯山下的盆地是洪泛区，某些时季地面会连续几天淹没在水下。对当地的蚂蚁来说，整个群体将不得不从巢穴中撤离，为了拯救蚁后和幼蚁，蚂蚁用身体造筏。研究人员收集蚂蚁在实验室中进行观察，他们发现年轻的蚂蚁处于筏的底部，这个位置看起来危险但实际上有利于生存。测试显示，年轻蚂蚁比成年蚂蚁的浮力更好，这让它们能像船上浮筒一样支撑整个筏。报告发表在PLOS ONE上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
