"the researchers documented several nests and eggs not previously described by science, particularly from species inhabiting remote regions of the Amazon and the Andes. By examining egg physiology along elevational gradients, they found that high-elevation species lose water at slower rates than lowland species, likely as an adaptation to reduce the risk of desiccation. These findings support the idea that egg physiology may constrain species distributions."

And the award for "best arachnology paper title of the year (so far)" goes to...

(Part of their aim is to "assess the impact of cave-related phenotypic traits (eye reduction, leg elongation, and pigmentation loss) on species distributional range".)

有點意外美洲檫樹是印地安文化的一種藥用植物，部分原因可能是他有肉桂味（畢竟都是樟科。而地理大發現的其中一個目的就是突破中東對香料貿易的壟斷。
不過他的草藥功能（尤其是性病，卻更受重視。足見即使人類的航海技術已經能跨洋旅行，卻對傳染病沒有太多辦法。至少在合成化學以前，人類只能有限的識別疾病，透過試誤進行介入。而至今對檫樹化學分析，其有效成分可能有致癌性，不過仍在研究初期，日後可能會視為重要的監管藥物。
在東亞對待檫樹，除了會是高海拔干擾地的先驅物種，以及寬尾鳳蝶屬的寄主植物之外好像沒有太多重視（畢竟太稀少不足以藥用。一直以來台灣看待檫樹就是一種稀有樟科，所以有人提到檫樹的利用，算是有點新的知識。
根據中國科學院和史密森尼博物館的研究主張Sassafras的多樣性高峰在44mya的北方大陸，亞洲和美洲的現生物種約在15mya分化。所以可能是始新世至中新世都是北方廣布，後來未知原因大範圍滅絕呈現東亞北美間斷分佈。

Les #jardins privés, des refuges précieux pour la biodiversité : « Nous avons des orvets, des lézards et pas mal de papillons »
Représentant une large part des territoires urbanisés, ces espaces privés sont souvent considérés comme des parcelles artificialisées alors qu’ils peuvent héberger une certaine #biodiversité. Villes et scientifiques tentent de mieux évaluer celle-ci pour la favoriser.
