从颈椎骨折、生命垂危到第一次爬出巢箱、自主站立、行走扑跳、淘气"炫饭"……两个月来，在西 宁野生动物园社交平台官方账号中，众多网友持续"追更"雪豹"凌小蛰"的康复日志，密切关注其体况改 善。 3月5日，6月龄重伤雪豹幼崽在三江源腹地、青海省玉树藏族自治州治多县野外被巡护员发现，及 时送往青海野生动物救护繁育中心治疗。目前，这只名为"凌小蛰"的雪豹身体渐渐好转，它将何去何 从、能否放归等话题持续引发讨论。 齐新章说："一只雪豹的生存活动需要相当规模的食草动物、草场支撑，它的种群健康于整体高山 生态系统而言具有典型指示意义。" 3月15日，救助人员为雪豹"凌小蛰"治疗。 (西宁野生动物园供图) 在连新明看来，雪豹作为三江源生物链顶端掠食者，具备科学研究、自然教育、文化传播等多元价 值。 "以几年前救助的雪豹'凌蛰'为例，它放归时佩戴的卫星追踪项圈，可用于观测记录迁徙路线。"连 新明称，"我们看到，它的活动范围很大，涉及多地超1057公里，这可能就是未来雪豹避开人类干扰的 栖息廊道。收集这些信息作为打造廊道的基础，从而保证雪豹栖息地完整性，让破碎片区的种群得以联 结、交流。" "应该说，救助和保护行动其实都是以人类 ...

20世纪70年代，受以《寂静的春天》为代表的环境保护思潮的影响，与生物多样性抵消（Biodiversity Offset）相关的理念开始出现在美国的政策和法规中。1992年《生物多样性公约》签署后，欧盟成员国 对生物多样性保护的关注度显著提升，近20年的时间里，生物多样性抵消机制在欧盟政策框架下得到系 统化的发展。与此同时，澳大利亚、新西兰、南非、英国等国基于自身情况开发出生物多样性抵消机 制。 生物多样性抵消是指为了缓解开发活动对生物多样性造成的负面影响而采取的行动。生物多样性抵消通 常被认为是减缓层级（避免、最小化、恢复、抵消）的最后一步，即在开展抵消前，开发商应确保已经 采取了避免影响、最小化影响、恢复生物多样性等三类措施。生物多样性抵消的目标一般分为生物多样 性无净损失（No Net Loss）和净增益（Net Gain）。无净损失指通过采取补偿措施，使项目造成的生物 多样性损失在量和质上得以平衡，整体不减少；而净增益则是在实现无净损失的基础上进一步提升生态 系统状况，实现生物多样性的总体改善。 多数国家的生物多样性抵消计划都以无净损失为目标，而英国2021年在《环境法案》中强制要求英格兰 地区的相关 ...

南古所团队打造的三叶虫体型数据库显示：最长70厘米，最小仅1毫米 海水氧含量，决定三叶虫是否"大高个" 南报网讯（记者 张安琪）在我们的印象中，远古动物都是"大高个"。科学家们一直致力于探寻生物体 型演化背后的奥秘，这不仅关乎生命演化，更能为理解当下生物与环境的关系提供重要线索。 日前，记者从中国科学院南京地质古生物研究所获悉，其"地球—生命系统早期演化"团队与美国科研人 员合作，建立了迄今数据最全的寒武纪和奥陶纪三叶虫体型数据库，对三叶虫的体型演化开展综合研 究，最新成果于北京时间5月3日2时在线发表于《科学进展》（Science Advances）上。 三叶虫是生活在海洋里的节肢动物，存在了约2.7亿年。它演化速度快、物种多样性高，且体型差异很 大，最小的仅1—2毫米，较大个体长度可达70厘米，是开展无脊椎动物化石体型演化研究的绝佳素材。 科研人员测量了1091个三叶虫属的4732个成年背壳的体型值，创建了目前数据最全、时间分辨率最高的 全球寒武纪和奥陶纪三叶虫的体型数据库。 "我们发现，全球尺度上寒武纪和奥陶纪三叶虫体型演化呈现阶段性，即体型在某些事件中发生快速变 化，之后长期停滞，直到下一次变化事件。 ...
