跟著城市嚮導「老臺北胃」，用味道認識臺北

很多朋友來臺北，
都會問我同一個問題：
「臺北小吃那麼多，到底該從哪裡開始吃？」
夜市裡攤位一字排開、老店藏在巷弄轉角，
看起來都很有名，卻又怕吃錯、踩雷，
結果行程走完，反而沒真正記住臺北的味道。
我常被朋友笑說是「老臺北胃」。
不是因為特別會吃，而是因為在這座城市待久了，
知道哪些味道是陪著臺北人成長的日常。
這篇文章，就是我整理的一份清單。
如果你第一次來臺北，
我會帶你從這 10 樣最具代表性的臺北小吃開始，
不追一時爆紅、不走浮誇路線，
而是讓你吃完後能真正理解
原來，這就是臺灣的小吃文化。
跟著老臺北胃走，
用最簡單的方式，
把臺北的味道，一樣一樣記在心裡。

我怎麼選出這 10 大臺北小吃？

在臺北，
你隨便走進一條夜市或老街，
都可以輕易列出 30 種以上的小吃。
所以這份清單，
不是「臺北最好吃」的排名，
 而是我站在「第一次來臺北的旅客」角度，
做的推薦。
身為一個被朋友稱作「老臺北胃」的人，
我選這 10 樣小吃時，心裡一直放著幾個原則。

一吃就知道：這就是臺灣味

燒烤、火鍋很好吃，
但換個城市、換個國家，也吃得到。
我挑的，是那種
只要一入口，就會讓人聯想到的臺灣味。
 不需要解釋太多，舌頭就能懂。

不只是好吃，而是有「臺北日常感」

臺北的小吃迷人，
不只在味道，
而在它融入生活的方式。
我在意的是：

1. 會不會出現在早餐、宵夜、下班後
2. 有沒有陪伴這座城市很久的記憶

吃完之後，你會記得臺北

最後一個標準很簡單。
如果你回到家，
還會突然想起某個味道、某碗熱湯、某個攤位的香氣
那它就值得被放進這份清單裡。

接下來的 10 樣臺北小吃，
就是我會親自帶朋友去吃的在地美食。
不趕行程、不拚數量，
而是一口一口，
慢慢認識臺北。

第 1 家：饌堂－黑金滷肉飯（雙連店）｜一碗就懂臺灣人的日常

如果只能用一道料理，
 來解釋臺灣人的日常飲食，
 那我一定會先帶你吃滷肉飯。
在臺北，滷肉飯不是什麼特別的節慶料理，
 而是從早餐、午餐到宵夜，
 默默陪著很多人長大的味道。
而在眾多滷肉飯之中，
饌堂－黑金滷肉飯（雙連店），
 我很常帶第一次來臺北的朋友造訪的一家。

為什麼第一站，我會選饌堂？
饌堂的滷肉飯，走的是**「黑金系」路線**。
滷汁顏色深、香氣厚，
卻不死鹹、不油膩。
滷肉切得細緻，
肥肉入口即化，搭配熱騰騰的白飯，
每一口都是很完整、很臺灣的味道。
對第一次吃滷肉飯的旅客來說，
這種風味夠經典、也夠穩定，
不需要太多心理準備，就能理解為什麼臺灣人這麼愛它。

不只是好吃，而是「現在的臺北感」
饌堂並不是那種躲在深巷裡的老攤，
空間乾淨、節奏俐落，
卻沒有失去滷肉飯該有的靈魂。
這也是我會推薦給旅客的原因之一：
它保留了臺灣小吃的核心味道，
同時也讓第一次來臺北的人，
吃得安心、坐得舒服。

老臺北胃的帶路小提醒
如果是第一次來：

1. 一定要點招牌黑金滷肉飯
   
2. 可以加一顆滷蛋，風味會更完整
3. 搭配簡單的小菜，就很有臺灣家常感

這不是那種吃完會驚呼「哇！」的料理，
而是會讓你在幾口之後，
慢慢理解
原來，臺灣人的日常，就是這樣被一碗飯照顧著。

第 2 家：富宏牛肉麵｜臺北深夜也醒著的一碗熱湯

如果說滷肉飯代表的是臺灣人的日常，
 那牛肉麵，
 就是很多臺北人心中最有份量的一餐。
而在臺北提到牛肉麵，
 富宏牛肉麵，
 幾乎是夜貓族、加班族、外地旅客一定會被帶去的一站。

為什麼老臺北胃會帶你來吃富宏？
富宏最讓人印象深刻的，
不是華麗裝潢，
而是那鍋永遠冒著熱氣的紅燒湯頭。
湯色濃而不混，
帶著牛骨與醬香慢慢熬出的厚度，
喝起來溫潤、不刺激，
卻會在嘴裡留下很深的記憶點。
牛肉給得大方，
燉到軟嫩卻不鬆散，
搭配彈性十足的麵條，
每一口都很直接、很臺北。

不分時間，任何時候都適合的一碗麵
富宏牛肉麵最迷人的地方，
在於它陪伴了無數個臺北的夜晚。
不管是深夜下班、看完演唱會、
或是剛抵達臺北、還沒適應時差，
這裡總有一碗熱湯在等你。
對旅客來說，
這種不用算時間、不用擔心打烊的安心感，
本身就是一種臺北特色。

老臺北胃的帶路小提醒
第一次來富宏，我會這樣點：

1. 紅燒牛肉麵是首選
   
2. 如果想吃得更過癮，可以加點牛筋或牛肚
3. 湯先喝一口原味，再視情況調整辣度

這不是精緻料理，
卻是一碗能在任何時刻撐住你的牛肉麵。
在臺北，
很多夜晚，
就是靠這樣一碗熱湯走過來的。

第 3 家：士林夜市・吉彖皮蛋涼麵｜臺北夏天最有記憶點的一口清爽

如果你在夏天來到臺北，
 一定會很快發現一件事
 這座城市，真的很熱。
也正因為這樣，
 臺北的小吃世界裡，
 才會出現像「涼麵」這樣的存在。
而在士林夜市，
 吉彖皮蛋涼麵，
 就是我很常帶旅客來吃的一家。

為什麼在夜市，我會帶你吃涼麵？
很多人對夜市的印象，
都是炸物、熱湯、重口味。
但真正的臺北夜市，
其實也很懂得照顧人的胃。
吉彖的涼麵，
冰涼的麵條拌上濃郁芝麻醬，
再加上切得細緻的皮蛋，
入口的第一瞬間，
就是一種「被降溫」的感覺。
那種清爽，
不是沒味道，
而是在濃香與清涼之間取得剛剛好的平衡。

皮蛋，是靈魂，也是臺灣味的關鍵
對很多外國旅客來說，
皮蛋是既好奇、又有點猶豫的存在。
但我常說，
如果要嘗試皮蛋，
涼麵是一個非常溫柔的起點。
芝麻醬的香氣會先接住味蕾，
皮蛋的風味則在後段慢慢出現，
不衝、不嗆，
反而多了一層深度。
很多人吃完後，
都會露出那種「原來是這樣啊」的表情。

老臺北胃的帶路小提醒
第一次點吉彖皮蛋涼麵，我會建議：

1. 一定要選皮蛋款，才吃得到特色
2. 醬料先拌勻，再吃，風味會更完整
3. 如果天氣真的很熱，這一碗會救你一整晚

這不是華麗的小吃，
卻非常臺北。
在悶熱的夜晚，
站在夜市人潮裡，
吃著一碗涼麵，
你會突然明白——

原來臺北的小吃，連氣候都一起考慮進去了。

第 4 家：胖老闆誠意肉粥｜臺北人深夜最踏實的一碗粥

如果你問我，
 臺北人在深夜、下班後，
 最容易感到被安慰的食物是什麼——
 我會毫不猶豫地說：肉粥。
而提到肉粥，
 胖老闆誠意肉粥，
 就是很多老臺北人口中的那一味。

為什麼這一碗粥，會被叫做「誠意」？
胖老闆的肉粥，看起來很簡單。
白粥、肉燥、配菜，
沒有華麗擺盤，也沒有複雜作法。
但真正坐下來吃，你會發現：
這碗粥，不敷衍任何一個細節。
粥體滑順、不稀薄，
肉燥香而不膩，
搭配各式家常小菜，
一口一口吃下去，
很自然就會放慢速度。
這種味道，
不是要你驚艷，
而是要你安心。

這不是觀光小吃，而是臺北人的生活片段
胖老闆誠意肉粥，
最迷人的地方，
就是它的客人。
你會看到：

1. 剛下班的上班族
2. 熬夜後來吃一碗熱粥的人
3. 熟門熟路、點菜不用看菜單的老客人

這些畫面，
比任何裝潢都更能說明這家店在臺北的位置。
對旅客來說，
這是一個走進臺北人日常的入口。

老臺北胃的帶路小提醒
第一次來吃，我會這樣建議：

1. 肉粥一定要點，這是主角
2. 配幾樣小菜一起吃，才有完整體驗
3. 不用急，慢慢吃，這碗粥就是要你放鬆

這不是為了拍照而存在的小吃，
而是那種
**會讓人記得「那天晚上，我在臺北吃了一碗很溫暖的粥」**的味道。

第 5 家：圓環邊蚵仔煎｜夜市裡最不能缺席的臺灣經典

如果要選一道
 最常出現在旅客記憶裡的臺灣小吃，
 蚵仔煎一定排得上前幾名。
而在臺北，
 圓環邊蚵仔煎，
 就是那種很多臺北人從小吃到大的存在。

為什麼蚵仔煎，這麼能代表臺灣？
蚵仔煎的魅力，
不在於精緻，
而在於它把幾種看似簡單的食材，
煎成了一種獨特的口感。
新鮮蚵仔的海味、
雞蛋的香氣、
地瓜粉形成的滑嫩外皮，
最後再淋上甜中帶鹹的醬汁，
一口下去，
就是夜市的完整畫面。
這種味道，
很難在其他國家找到替代品。

圓環邊，吃的是記憶感
圓環邊蚵仔煎，
沒有多餘的包裝，
也不刻意迎合潮流。
它留下來的原因很簡單
味道夠穩、節奏夠快、
讓人一吃就知道「對，就是這個」。
對旅客來說，
這是一家
不需要研究、不需要比較，就能安心點蚵仔煎的地方。

老臺北胃的帶路小提醒
第一次吃蚵仔煎，我會這樣建議：

1. 趁熱吃，口感最好
   
2. 不用急著加辣，先吃原味
3. 醬汁是靈魂，別急著把它拌掉

蚵仔煎不是細嚼慢嚥的料理，
它屬於人聲鼎沸、鍋鏟作響的夜市時刻。
站在人群裡，
吃著一盤熱騰騰的蚵仔煎，
你會很清楚地感受到
這，就是臺北的夜晚。

第 6 家：阿淑清蒸肉圓｜第一次吃肉圓，就該從這裡開始

說到臺灣小吃，
 很多人腦中一定會出現「肉圓」兩個字。
但真正吃過之後才會發現，
 肉圓，從來不只有一種樣子。
在臺北，
 阿淑清蒸肉圓，
 就是我很常拿來介紹「清蒸派肉圓」的一家。

清蒸肉圓，和你想像的不一樣
不少旅客對肉圓的第一印象，
來自油炸版本，
外皮厚、口感重。
而阿淑的清蒸肉圓，
完全是另一個方向。
外皮晶瑩、滑嫩，
帶著自然的彈性，
不油、不膩，
一入口反而顯得清爽。
內餡扎實，
豬肉香氣清楚，
搭配特製醬汁，
味道層次簡單卻很乾淨。

為什麼我會推薦給第一次來臺北的旅客？
因為這顆肉圓，
不需要適應期。
它不刺激、不厚重，
即使是第一次嘗試臺灣小吃的人，
也能輕鬆接受。
對旅客來說，
這是一顆
「吃得懂、也記得住」的肉圓。

老臺北胃的帶路小提醒
第一次來阿淑，我會這樣吃：

1. 直接點一顆清蒸肉圓，吃原味
2. 醬汁先別全部拌開，邊吃邊調整
3. 放慢速度，感受外皮的口感變化

這不是夜市裡熱鬧喧囂的料理，
而是那種
安靜地展現臺灣小吃功夫的味道。
當你吃完這顆肉圓，
會更明白一件事
臺灣小吃的魅力，
往往藏在這些細節裡。

第 7 家：胡記米粉湯｜一碗最貼近臺北早晨的味道

如果說前面幾樣小吃，
 是臺北的熱鬧與記憶，
 那麼米粉湯，
 就是這座城市最真實的日常。
而在臺北，
 胡記米粉湯，
 是很多人從小吃到大的存在。

為什麼米粉湯，這麼「臺北」？
米粉湯不是重口味料理，
它靠的不是刺激，
而是一碗清澈卻有深度的湯。
胡記的湯頭，
用豬骨慢慢熬出香氣，
喝起來清爽、不油，
卻能在喉嚨留下溫度。
米粉細軟，
吸附湯汁後入口順滑，
簡單到不能再簡單，
卻正是臺北人習以為常的早晨風景。

配菜，才是這一碗的靈魂延伸
在胡記吃米粉湯，
主角雖然是湯，
但真正讓人滿足的，
往往是那些小菜。
紅燒肉、豬內臟、燙青菜，
隨意點上幾樣，
湯一口、菜一口，
就是很多臺北人記憶中的早餐組合。
對旅客來說，
這是一種
不需要解釋，就能融入的臺北生活感。

老臺北胃的帶路小提醒
第一次來胡記，我會這樣建議：

1. 一定要點米粉湯，湯先喝
2. 再配 1～2 樣小菜，體驗會完整很多
3. 這一餐適合慢慢吃，不用趕

這不是為了觀光而存在的小吃，
而是一碗
每天準時出現在臺北人生活裡的湯。
當你坐在店裡，
聽著湯勺碰撞的聲音，
你會突然感覺到——
原來，臺北的早晨，
就是從這樣一碗米粉湯開始的。

第 8 家：藍家割包｜一口咬下的臺灣街頭記憶

如果要選一道
 外國旅客一看到就會好奇、吃完又會記住的小吃，
 割包，一定在名單裡。
而在臺北，
 藍家割包，
 就是我很放心帶旅客來認識這道經典的一站。

割包，為什麼被叫做「臺灣漢堡」？
割包的結構其實很簡單：
鬆軟的白饅頭、
燉得入味的滷五花肉、
酸菜、花生粉、香菜。
但真正迷人的，
是這些元素組合在一起時，
形成的層次感。
肉香、甜味、鹹味、清爽度，
在一口之間同時出現，
沒有誰搶戲，
卻彼此剛好。
這種平衡感，
正是臺灣小吃很迷人的地方。

藍家割包不是走浮誇路線，
它給人的感覺很直接
就是你期待中的割包樣子。
饅頭柔軟不乾，
五花肉肥瘦比例恰到好處，
入口即化卻不膩口，
花生粉的甜香收尾，
讓整體味道非常完整。
對第一次吃割包的旅客來說，
這是一個
不會出錯、也很容易愛上的版本。

老臺北胃的帶路小提醒
第一次吃藍家割包，我會這樣建議：

1. 直接點招牌割包，不要改配料
2. 如果有香菜，建議保留，味道會更完整
3. 趁熱吃，饅頭口感最好

割包不是精緻料理，
卻非常有記憶點。
站在街頭，
拿著一顆熱騰騰的割包，
邊走邊吃，
你會很清楚地感受到
這一口，就是臺灣的街頭生活。

第 9 家：御品元冰火湯圓｜臺北夜晚最溫柔的一碗甜

吃了一整天的臺北小吃，
 到了這個時候，
 胃其實已經差不多滿了。
但只要天氣一涼，
 或夜色慢慢降下來，
 你還是會想找一碗——
 不是為了吃飽，而是為了舒服的甜點。
這時候，我通常會帶你來 御品元冰火湯圓。

為什麼叫「冰火」？這碗湯圓的關鍵就在這裡
御品元最有特色的地方，
就在於它的「冰火交錯」。
熱騰騰的湯圓，
外皮軟糯、內餡濃香，
搭配冰涼清甜的桂花蜜湯，
一口下去，
溫度在嘴裡交替出現。
不是衝突，
而是一種很細膩的平衡。
這樣的吃法，
也正是臺灣甜點很擅長的地方——
不張揚，但很有記憶點。

這是一碗，會讓人慢下來的甜點
和夜市裡熱鬧的甜品不同，
御品元的冰火湯圓，
更像是一個讓人停下腳步的存在。
你會發現，
坐在這裡吃湯圓的人，
說話聲都會不自覺地變小。
對旅客來說，
這不只是吃甜點，
而是一個
把白天的熱鬧慢慢收進回憶裡的時刻。

老臺北胃的帶路小提醒
第一次吃御品元，我會這樣建議：

1. 點招牌冰火湯圓，體驗完整特色
2. 先單吃湯圓，再搭配湯一起吃
3. 放慢速度，這一碗不適合趕時間

這不是為了拍照而存在的甜點，
而是一碗
會讓你記得「那天晚上在臺北，很舒服」的湯圓。

第 10 家：頃刻間綠豆沙牛奶專賣店｜把臺北的味道，留在最後一口清甜

走到這一站，
 其實已經不需要再吃什麼大份量的東西了。
這時候，
 最適合的，
 是一杯不吵鬧、不張揚，
 卻會默默留在記憶裡的飲品。
頃刻間綠豆沙牛奶，
 就是我很常用來替一天畫下句點的選擇。

綠豆沙牛奶，為什麼這麼「臺灣」？
在臺灣，
飲料不只是解渴，
而是一種生活節奏。
綠豆沙牛奶看起來簡單，
但真正好喝的版本，
靠的是火候、比例，
還有耐心。
頃刻間的綠豆沙，
口感細緻、不粗顆，
甜度自然、不膩口，
牛奶的加入，
讓整杯變得柔順而溫和。
這不是衝擊味蕾的飲料，
而是一種
喝完之後，會覺得剛剛那一刻很舒服的甜。

為什麼我會用它當作最後一站？
因為它很臺北。
你可以外帶，
邊走邊喝；
也可以站在店門口，
慢慢把杯子喝空。
沒有儀式感，
卻很真實。
對旅客來說，
這杯綠豆沙牛奶，
就像是把今天吃過的所有味道，
溫柔地整理好，
帶走。

老臺北胃的帶路小提醒
第一次喝頃刻間，我會這樣建議：

1. 直接點招牌綠豆沙牛奶
   
2. 正常甜就很剛好，不用特別調整
3. 找個角落慢慢喝，別急著趕路

這一杯，
不會讓你驚呼，
卻會在回程的路上，
突然想起來。
原來，臺北的味道，是這樣結束一天的。

老臺北胃帶路｜這 10 口，就是我心中的臺北

寫到這裡，
 其實已經不是在推薦哪一家小吃了。
而是在回頭看，
 這座城市，是怎麼用食物陪著人生活的。
滷肉飯、牛肉麵、肉粥、米粉湯，
 不是為了成為觀光名單而存在，
 而是每天默默出現在臺北人的日子裡。
夜市裡的蚵仔煎、涼麵、割包，
 熱鬧、吵雜、節奏很快，
 卻也正是臺北最真實的樣子。
而最後那碗湯圓、那杯綠豆沙牛奶，
 則是在一天結束時，
 替味蕾留下一個溫柔的句點。

如果你問我，
「這 10 家是不是臺北最好吃的小吃？」
我會說，
它們不一定是排行榜第一名，
卻是我真的會帶朋友去吃的版本。

看到冒著熱氣的小攤，
你也會開始懂得，
為什麼老臺北胃，
總是記得這些看似平凡的滋味。
因為，真正留在心裡的，
從來不是吃過多少，
而是哪一口，讓你想起臺北。

胡記米粉湯價格合理嗎？

走完這 10 家，

A new study has revealed that the evolution of suberin lamellae in seed plants played a crucial role in their dominance over ferns in Earth’s changing climate. This discovery offers new insights into plant evolution and has significant implications for enhancing drought resistance in crops. A recent study published in Nature Plants by Chao Daiyin’s team at the Center for Excellence in Molecular Plant Sciences of the Chinese Academy of Sciences, along with Lyu Shiyou’s team at Hubei University, has revealed, for the first time, the mystery behind the rise of seed plants from the perspective of specialized cell wall evolution. Seed plants are the most advanced plant group in the world, accounting for two-thirds of all plant species and shaping the predominant flora of our world. However, the Earth was very different over 300 million years ago during the Carboniferous period, when ferns were the dominant flora, with towering tree ferns dominating the ecological landscape. Most of the coal resources on Earth today came from fern plants of that period, hence the name “Carboniferous.” However, paleontological research reveals a turning point at the end of the Carboniferous period, with Earth’s climate suddenly becoming cold and arid. As a result, ferns began to decline, paving the way for the rise of seed plants. Nevertheless, this significant evolutionary event is marked by many unsolved mysteries, with one of the most important mysteries being: What specific advantages did seed plants evolve that allowed them to transition from a weaker position to a thriving one by the end of the Carboniferous period? Key Findings on Plant Root Structures Roots are essential organs for absorbing and transporting water and mineral nutrients in plants, and the endodermis is the core of the root, controlling water and mineral transport. The endodermis cell wall features a hydrophobic, lignin-based Casparian strip tightly anchored to the endodermal cell membrane, thus forming a barrier to prevent the free diffusion of substances. Additionally, the suberin lamellae are specialized cell wall structures that envelop the entire surface of endodermal cells. Research indicates that both the Casparian strip and suberin lamellae play essential roles in plant nutrient balance and water transport, but their functions are significantly different. Chao’s group had previously made breakthroughs in understanding the formation and anchoring of the Casparian strip. However, the evolutionary basis of suberin lamellae and their role in plant evolution had not yet been resolved. Evolutionary Insights into the Casparian Strip and Suberin Lamellae This study used a series of advanced cell biology and analytical chemistry techniques to conduct in-depth research on representative plant species from 18 different evolutionary nodes with the aim of unveiling the secrets of the origin of the Casparian strip and suberin lamellae. Surprisingly, the researchers found that the Casparian strip exists in all vascular plants, including ferns, lycophytes, gymnosperms, and angiosperms, while suberin lamellae are only present in gymnosperms and angiosperms (both collectively referred to as seed plants). This evidence suggests that the Casparian strip and suberin lamellae did not originate simultaneously; the former emerged from the common ancestor of all vascular plants, while the latter evolved in the common ancestor of seed plants. This finding challenges the longstanding assumption regarding suberin lamellae and offers new perspectives for studying the evolution of these structures. Gene Expansion and Suberin Lamellae in Seed Plants To investigate how suberin lamellae evolved in the common ancestor of seed plants, the researchers conducted molecular evolutionary analyses of the genes involved in suberin lamellae formation and their homologs, with these results: Although most of these genes had evolved before the appearance of vascular plants, significant expansion occurred in the common ancestor of seed plants. This expansion suggested that gene duplication likely led to functional innovations, thus enabling the genes responsible for synthesizing suberin lamellae to emerge in the common ancestor of seed plants. To confirm this hypothesis, the researchers investigated homologous genes of the core MYB transcription factors involved in suberin formation in fern plants, lycophytes, gymnosperms, and angiosperms. These genes were found to be widespread in all these plant groups. However, a significant expansion of homologous genes occurred in the common ancestor of gymnosperms and angiosperms. The researchers revealed that the expanded homologous genes in gymnosperms and angiosperms could initiate suberin lamellae formation, while the homologous genes in fern plants and lycophyte plants had no such function. This finding confirmed that the function of MYB transcription factors initiating suberin synthesis was acquired in seed plants through gene expansion. The Role of Suberin Lamellae in Plant Adaptation As Earth’s climate became dry in the late Carboniferous period, ferns began to decline and seed plants increased. Since suberin has waterproof properties, the researchers hypothesized that the emergence of suberin lamellae might have contributed to the drought adaptability of seed plants, thus promoting their rise after the onset of arid conditions. They later confirmed this hypothesis by using two Arabidopsis genetic materials with suberin defects, thereby demonstrating that suberin-deficient Arabidopsis was more sensitive to drought. Furthermore, Raman spectroscopy and nuclear magnetic resonance revealed the crucial significance of suberin lamellae in enhancing the efficiency of vascular water transport. Specifically, since water molecules are capable of free diffusion across cell membranes in the absence of suberin lamellae, plants without suberin lamellae, such as ferns and horsetails, experience significant water leakage from endodermal cell membranes when subjected to osmotic stress, resulting in low transport efficiency. Seed plants, with suberin lamellae fully enveloping their endodermal cells, almost completely block the free diffusion of water molecules. Thus, their water leakage rate under osmotic stress is only 1%–2% compared to fern plants and lycophyte plants. This waterproofing effect greatly enhances the efficiency of water transport in the vascular tissues of seed plants under drought conditions, thereby increasing their drought resistance. Based on this, the researchers proposed a model for the rise of seed plants: In the moist climate of the Carboniferous period, fern plants with no suberin lamellae had higher water and nutrient absorption efficiency and were better adapted to the environment, thus causing them to thrive. However, during the late Carboniferous period, the onset of a dry climate provided an advantage for seed plants that had evolved suberin lamellae. They possessed a more efficient water transport system and stronger drought tolerance, allowing them to gradually replace ferns and become the dominant life forms on Earth’s surface. This study not only unveils the mystery of the origin of the Casparian strip and suberin lamellae but also provides evidence, for the first time, that the emergence of suberin lamellae drove the rise of seed plants, based on a new perspective. Furthermore, it identifies the important role of suberin lamellae in plant adaptation to adverse conditions such as drought. As a result, this study has significant implications for enhancing plant drought resistance, elucidating plant salt and drought tolerance mechanisms, and developing drought-resistant crop varieties.

Leshyk/Natural History Museum of Los Angeles County Scientists have discovered that terrestrial ecosystems are more prone to collapse from significant animal life loss than marine ecosystems, with the impacts lasting longer on land. A new study published in Proceedings of the Royal Society B reveals that terrestrial ecosystems were more severely affected by the end-Triassic extinction than marine ecosystems. Furthermore, the recovery period for these terrestrial environments was longer compared to their marine counterparts, a finding that was unexpected. This discovery holds significant implications for the ongoing global extinction event, which is largely driven by human-induced climate change. “If you remove a significant component of critters from terrestrial ecosystems on land, those ecosystems fall apart and collapse much more easily than what happens in the oceans,” said Dr. Hank Woolley, co-author and NSF Postdoctoral Research Fellow at the Dinosaur Institute. “And secondly, it takes longer for terrestrial ecosystems to recover from a mass extinction event than marine ecosystems.” Collaborative Research Efforts and Methodology This project — which was undertaken by Woolley and many other paleoecologists and geologists from NHM and beyond — is the first documented scientific study taking an in-depth look at the end-Triassic extinction event’s effects on both terrestrial and marine ecosystems. In addition to Woolley, NHM Dinosaur Institute PhD students Paul Byrne and Kiersten Formoso (the latter now a newly-minted Presidential Postdoctoral Fellow at Rutgers University), and Postdoc Dr. Becky Wu, co-authored the study with their USC colleagues. “This research endeavor also combined the expertise of a diverse array of paleobiology, paleoecology, and geobiology researchers at the University of Southern California and the Natural History Museum,” said Dr. Kiersten Formoso. “It’s exciting to get such an assemblage of authors across disciplines to join together to tackle interesting questions about the past and natural world.” Skeleton of the early dinosaur Coelophysis bauri from the Late Triassic.

So while there are a lot of reconstructions of marine ecosystem change across mass extinctions, we have never been able to study terrestrial ecosystem change in the same way. We hope that this new terrestrial ecospace framework will open the door for future studies comparing how marine and terrestrial communities respond similarly or differently to rapid climate change events,” said co-author Dr. Alison Cribb, now 1851 Research Fellow at the University of Southampton. “As a research group that studies the paleobiology of life in the oceans and on land, with study systems ranging from billion-year-old stromatolites to dinosaurs, we thought that this would be a unique opportunity to bring our breadth of expertise together to tackle a fascinating and pressing topic—mass extinctions—in a new way,” said Woolley. While the earliest dinosaurs first appeared and spread more than 230 million years ago during the Triassic period, a catastrophic bout of CO2-fueled global warming led to the end-Triassic extinction event 201.5 million years ago, wiping out around 76% of all marine and terrestrial life. The effects of mass extinction events on marine environments have been well studied by creating ecospaces—3D representations that classify animals by how they feed and move and where they live—but the technique was never applied to terrestrial ecosystems. Until now, that is. Findings and Implications The new team of scientists compiled more than a thousand records from the Paleobiology Database to build the first terrestrial ecospace across the end-Triassic mass extinction. Next, they sorted each occurrence across the three axes to understand how well-represented different groups of animals were in terms of how they survived — eating insects while living mostly in the trees or scavenging for larger animals on the ground, for example. The researchers then took this new framework and compared it to a marine ecospace of the end-Triassic extinction. Graphic representation of the study concept and findings. Credit: C. Henrik Woolley/Natural History Museum of Los Angeles County “Our findings reveal that in the wake of the end-Triassic mass extinction, land and sea recovered differently, with land ecosystems experiencing higher extinction severity and taking more time than the oceans to recover groups that filled certain ecological roles. This was because land ecosystems had fewer groups occupying these roles, in contrast with that of the oceans where many taxonomic groups may be doing the same or similar things,” said Formoso. Their findings could have a stark warning for our modern terrestrial ecosystems as we struggle with growing extinctions in the wake of human-caused climate change. For one thing, the end-Triassic extinction event involved volcanoes spewing out CO2. One of the other takeaways from the results is that no mass extinction event will have the same effects across different ecosystems. Life on land is markedly different—flowering plants are just one group that didn’t exist during the Triassic—but knowing those ecosystems might be even more vulnerable than previously thought should raise alarm bells. Broader Impacts and Future Directions “Understanding how life responded to climate change in the past is a major aim of paleontology and one that provides us insight and tools for addressing our modern biodiversity crisis. However, this requires detailed knowledge across a diverse set of organisms, ecosystems, and environments. One of the unique aspects of our collaborative paleontology program at NHM and USC is that it combines an un-motley crew of paleontologists with expertise spanning species, systems, and time – all of which make big-picture studies like this paper possible. As a result, our paleontological impact is greater than the sum of its paleontologists!” says Dr. Nathan Smith, Curator of the Dinosaur Institute at NHM, and Woolley’s PhD and Postdoc supervisor. The new framework developed for the study could also help scientists better understand mass extinctions across history. That could include our ongoing crisis and possibly inform more effective mitigation and conservation efforts. The collaborative project also demonstrates the value fossils and the fossil record can have when it comes to understanding not just the world of the dinosaurs, but our own rapidly changing climate. “The Natural History Museums of Los Angeles County house millions of fossils spanning the entire history of life,” said Dr. Luis Chiappe, Senior Vice President of Research & Collections, and Gretchen Augustyn Director of the Dinosaur Institute. “Our collections are well-suited to address a wealth of questions related to past and present extinctions.” Reference: “Contrasting terrestrial and marine ecospace dynamics after the end-Triassic mass extinction event” by Alison T.

Another new wasp species, Chrysonotomyia susbelli, was discovered by Rice researchers. Credit: Rice University The wasp’s color is “almost identical” to the official colors of the residential college. A new wasp species, Chrysonotomyia susbelli, has been discovered in Houston, Texas, becoming the 18th species identified by Rice University’s Scott Egan and his research team since 2014. This marks the fourth wasp species found on the university campus in the past seven years, shedding light on the hidden world of parasitoid wasps and the complex ecosystems that flourish in our immediate surroundings. The Chrysonotomyia susbelli is a parasitoid wasp, about 1 millimeter long, that emerges from galls, or tumorlike growths created by the gall wasp Neuroterus bussae found on southern live oak leaves. The galls serve as microhabitats within which larvae feed, develop and pupate. The research team’s study was published in the journal ZooKeys. Significance of the New Species “Chrysonotomyia susbelli represents the sixth species of its genus described from North America and the first globally known to parasitize cynipid gall wasps,” said Egan, an associate professor of ecology and evolutionary biology. The wasp was discovered and named by Brendan O’Loughlin, a Rice senior and the study’s first author. “The wasp’s goldenrod color is almost identical to the official colors of Wiess College, my residential college,” O’Loughlin said. The Chrysonotomyia susbelli is a parasitoid wasp, about 1 millimeter long. Credit: Rice University To confirm the uniqueness of the species, the research team conducted a genetic analysis and a detailed study of the wasp’s physical features under a microscope. Its investigation also included a review of the historical literature to ensure that the species had not been previously described. This research was complemented by DNA barcode data and observations of the wasp’s natural history, including host associations and a unique leaf-scanning behavior exhibited by female wasps. The researchers also modified the identification key of New World members, groups of species found exclusively in the Americas, to incorporate this new species. Importance of Local Biodiversity Egan emphasized the importance of studying local biodiversity. “You don’t have to travel to a distant rainforest to find new and beautiful things — you just have to step outside and look,” he said. The discovery hints at a previously unexplored ecological niche involving Chrysonotomyia parasitoids, cynipid gall wasps, and oaks, suggesting that there may be many more undiscovered species within this system. “Generations of Chrysonotomyia susbelli have likely lived unnoticed on the oaks of Rice University since its founding,” Egan said.
