That suggests that the trees were deciduous, meaning that they shed their leaves at the same time.
這說明樹木會在每年的相同時間內落葉。
But fossilized wood from the region tells a different story.
但是該地區的木化石卻又說明了另一種情況。
How so?
原因是？
Cells in the tree rings show a pattern of growth that's consistent with evergreen trees, meaning trees that don't shed their leaves.
年輪的細胞體現出樹木的生長方式與常青樹相同。也就是說它們不會落葉。
So the ancient Antarctic forests were probably a mix of evergreen and deciduous trees.
因此，古代的南極森林可能是一片常青樹和落葉樹的雜交林。
Right. Analysis of carbon molecules in the fossil woods shows something similar.
對木化石中碳分子的分析結果也顯示有所相似之處。
And it also suggests that the forests have some similarities to tropical forests today.
真奇怪，同時，分析結果還表明了南極森林和今天的熱帶雨林也存在一定的相似。
Weird1 Another question is how Antarctic forests dealt with constant daylight half the year and near total darkness the other half.
另一個問題就是南極森林是如何適應極晝和極夜現象的。
Wouldn't that mess with their ability to photosynthesize?
這難道不會擾亂它們光合作用的能力嗎?
Good question! More research might reveal the answer.
問得好！想要找出答案可能還需要進行更多的研究。
