熊蜂饿了也“催单”——啃咬叶片使植物提前开花（图）
熊蜂 啃咬叶片 植物 提前开花
2020/6/11
熊蜂是群机智的家伙：当蜂巢附近的植物还没有开花、花粉稀少时，工蜂会想办法迫使它们开花。近日，发表在《科学》杂志上的一项研究显示，这些昆虫会刺穿植物的叶子，导致植物的开花时间比正常情况下平均提前30天。熊蜂催花技术的演化过程，以及这些植物通过开花来响应熊蜂叮咬的原因目前仍不清楚。但研究人员表示，在如此为人熟知的生物身上发现一种新行为是非常了不起的。

海平面上升 红树林
2020/6/8
近日，一项新研究分析了全新世冰川消退对红树林生长的影响，让人们得以一窥生态系统将如何应对未来迅速上升的海平面。澳大利亚麦考瑞大学、美国罗格斯大学等机构研究人员在《科学》杂志上发表论文称，如果温室气体排放不减少，到2050年，红树林将无法承受海平面上升之重。红树林主要分布在温暖气候地区，是宝贵的沿海生态系统。红树林储存了大量的碳，有助于保护海岸线，为鱼类和其他物种提供栖息地。研究人员利用过去1万年的...

澳大利亚 林火 生物多样性 巨大影响
2020/1/21
2019年7月以来，高温天气和干旱导致澳大利亚多地林火肆虐。截至目前，林火灾害已致28人死亡，2600多栋民居被毁，过火面积超过1000万公顷。持续数月的森林大火对当地生态系统和野生动物更是造成了巨大影响。被列入世界遗产名录的悉尼蓝山地区，占地103万公顷，这里有包括“活化石”植物瓦勒迈松在内的大量珍稀濒危物种。悉尼大学环境科学讲师阿伦·格林维尔日前表示，蓝山八成区域已经被林火烧毁。
