2026biology talkshow:燃燒的驪歌-鳳凰木的物候學
from 雷比特生物空中講 · host 雷比特老師
深入探討鳳凰木的物候學特徵與演化背景，解釋其花期之所以與台灣畢業季重疊，是源於原生地馬達加斯加乾濕季循環的氣候巧合。詳細解析葉片透過離子幫浦控制膨壓以產生睡眠運動的生理機制，並指出二回羽狀複葉具備高效光合作用與抗風功能。進一步揭示花瓣上的旗瓣如何導引昆蟲授粉，以及其巨大莢果原本依賴已滅絕的大型動物傳播種子的演化遺憾。儘管鳳凰木在世界各地作為行道樹廣泛分布，但在家鄉卻面臨瀕危困境，呈現出強烈的生態反差。 聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://gemini.google.com/share/a050fc5123cc Powered by Firstory Hosting
