koala

澳大利亚东部和东南部的标志性有袋类动物，体重最大可达15千克，为了节省低热量桉树叶食物所提供的能量，每天最多睡眠22小时。高度特化，能够处理会致大多数其他哺乳动物死亡的有毒桉树成分，拥有专门适应解毒功能的肠道微生物群。因衣原体病、栖息地开发和气候变化导致种群锐减，2022年被列为濒危物种。

Peronospora ranunculi 是 Peronosporaceae 科的卵菌霜霉病病原体，是毛茛属（Ranunculus）植物的专性活体营养寄生物。感染叶片和茎，在上表面引起褪绿病斑，下表面出现典型的灰色孢子形成。与其他 Peronospora 种一样，通过气流散布的孢子囊传播，需要活的寄主组织才能完成生活史。
