许多人曾以为，蘑菇繁殖是通过被动的丢下孢子，依靠周围的阵风传播到四面八方。但最新研究发现，蘑菇在传播自己的种子上面要积极主动的多：它们自己"制造风"去传播孢子。蘑菇通过让水分蒸发去创造空气流动，它基本上不去努力防止蒸发水。液态水蒸发需要吸收热量，因此会导致周围空气温度下降，而冷空气密度要高于热空气，因而能形成空气流动。研究发现，这股升力可以让孢子水平垂直移动10厘米。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.
