研究结果显示，到本世纪末，预计将有近8000种物种面临不适宜的生存条件，包括气候变化导致的极端 高温以及人类活动导致的栖息地丧失。 以色列内盖夫本-古里安大学、英国牛津大学等机构的研究人员在学术期刊《全球变化生物学》上报告 说，城市化、农业扩张等土地利用方式变化以及其他人类活动，正在破坏动物的自然栖息地，并可能引 发大规模物种灭绝。 研究人员对近3万种哺乳动物、鸟类、爬行动物和两栖动物的生存状况进行了分析，研究了它们偏好的 栖息地环境、可承受的温度范围，以及21世纪气候变化和土地利用变化的预测情况。 新华社耶路撒冷12月18日电（记者王卓伦 冯国芮）一个国际团队日前发布的研究显示，由于气候变化 引发极端高温、人类活动挤压栖息地，到本世纪末，近8000种哺乳动物、鸟类、爬行动物和两栖动物可 能面临灭绝风险。 研究指出，非洲萨赫勒地区、巴西大片区域以及中东部分地区受影响尤为严重。地球未来可能面临物种 多样性大幅下降、生态系统遭受破坏的局面，这将对人类生存环境造成严重影响。研究人员希望采取全 球行动加强环境和自然保护，以维护生物多样性。（完） ...

研究显示，中非国家由于湿润森林的持续存在，仍保持着较高的生物多样性完整度，而西非地区由 于森林和稀树草原严重退化，生物多样性完整度较低。此外，超过80%的现存野生动植物种群生活 在"生产性土地"，即人类与自然共存的森林和牧场，而非保护区内。 研究通讯作者、斯泰伦博斯大学可持续转型中心高级研究员海莉·克莱门茨说，对于非洲大型哺乳 动物来说，保护区仍然至关重要，但仅靠保护区不足以遏制生物多样性减少，对"生产性土地"进行可持 续管理是维护生物多样性和保障生计的关键。 克莱门茨表示，许多全球生物多样性评估无法反映非洲的现实情况。通过直接与研究和管理非洲生 态系统的人士合作，研究人员得以掌握更真实的情况。研究报告3日发表在英国《自然》杂志上。 南非斯泰伦博斯大学3日发表的一份声明说，一项由非洲研究人员主导的最新研究显示，撒哈拉以 南非洲的生物多样性较工业革命前已减少近四分之一。 声明说，这项研究耗时超5年，汇集了在该地区工作的研究人员、野外生态学家、护林员、导游和 博物馆馆长等200名专业人士，绘制了非洲生物多样性完整度指数地图。 研究显示，撒哈拉以南非洲的生物多样性较工业革命前减少了24%，意味着该地区的植物和动物平 ...
