研究人员利用公开的生物多样性数据集，对来自35个现有类群的70814种动物的数据进行了研究。他们按照国际自然保护联盟的评估标准，根 据类群和气候变化风险对这些物种进行了分类。 一项新研究表明，超过3500种动物物种正受到气候变化的威胁。该研究于20日发表在《生物科学》期刊上。 领导此项研究的俄勒冈州立大学生态学教授威廉·里普尔预计，气候变化不断加剧将成为威胁地球动物的第三大主要因素。地球野生动物正面 临生存危机，而人类现在正处于这场危机中。 研究发现，在六个不同的纲中，至少有四分之一的物种受到气候变化的威胁。这些纲包括蛛形纲动物和唇足纲动物（如蜈蚣），以及珊瑚虫 纲动物和水螅纲动物（与水母和珊瑚相关的海洋无脊椎动物）。其他纲中也有较小比例的物种正直接面临气候变化带来的风险。研究人员尤其关 注海洋中的无脊椎动物，因为它们迁移能力有限，无法迅速避开恶劣环境。 由于水温不断升高，以色列海岸线附近的软体动物数量减少了90%，这表明无脊椎动物非常脆弱。其他例子还包括，2021年太平洋西北部热 穹顶事件期间，数十亿潮间带无脊椎动物死亡；2016年，一场严重的海洋热浪来袭，大堡礁29%的珊瑚遭遇灾难性死亡。 里普尔指出，大 ...

3.2亿年前，当脊椎动物离开水域来到陆地生活时，它们面对的是全新的挑战：如何适应陆地环 境，如何在陆地上找到食物、躲避危险、寻找伴侣。此后进一步演化出的鸟类更是需要适应长时间飞行 迁徙的特殊生活方式。 原标题：新研究揭秘3.2亿年动物大脑进化路径 当人们提到高智商动物时，通常会想到猴子、猩猩等灵长类，或宠物狗、海豚。但鸽子或麻雀等鸟 类，其实也展现出了媲美灵长类的工具使用和社会认知能力。 这听起来或许有点不可思议，但最新科学研究显示，鸟类、哺乳类甚至龟类的大脑在过去3.2亿年 里，经历了一场精彩的演化历程，走出了截然不同但又殊途同归的智慧发展之路。 5月13日，华大生命科学研究院联合中国科学院深圳先进技术研究院、郑州大学生命科学学院、中 国科学院脑科学与智能技术卓越创新中心等机构，共同揭开了跨越3.2亿年的大脑神经元演化之谜。相 关研究论文发表于国际期刊《发育细胞》。 构建跨物种单细胞图谱 形成基因双轨演化机制 鸟类的小脑占全脑的比例较高，细胞类型的复杂程度也相对较高，此前有推测认为这可能与它们适 应飞行等因素相关。 该研究首次在鸟类小脑中鉴定出SVIL+浦肯野细胞亚型，其基因表达谱显著区别于哺乳类的 ALD ...
