Cold spots hotspots key rapid biodiversification
2020/12/18
The Amazon rainforest may be a hotspot for animal and plant diversity, but Louisiana State University scientists report that new species form there less often than previously thought. Places such as d...
Imagine a tropical forest, and you might conjure up tall trees hung with vines, brightly colored birds, howling monkeys and ... rain. Indeed, precipitation patterns, along with temperature, dictate wh...

Plucky, beautiful, and declining in numbers at about 2% annually, rufous hummingbirds make their long annual migrations in different timing and route patterns based on age and sex, new U.S. Natio...
近年来，南非生物入侵问题日趋严重。入侵物种每年给南非带来的经济损失高达65亿兰特（约27.5亿人民币），南非政府每年在控制入侵物种上的支出为15亿兰特（约6.3亿人民币）。除经济损失外，入侵物种还在不断威胁着南非生物多样性及生态系统服务，可能带来不可估量的生态损失。近日，金山大学研究人员在《Ecosystem Services》杂志发表最新研究成果。该研究使用大数据，将2011年南非国家人口普查中...
When it comes to climate, plants and animals aren't so different（图）

Despite fundamental differences in their biology, plants and animals are surprisingly similar in how they have evolved in response to climate, according to a new National Science Foundation-funde...
Diversity plays a key role in maintaining the stability of plant and animal life. But it's difficult to scale up smaller experiments to understand how changes will impact larger ecosystems.A new study...

澳大利亚林火对生物多样性造成巨大影响
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。

一种科学上认为已消失的物种被重新发现
蹄类动物 生态学研究 栖息地
2022/3/7
根据英国《自然 · 生态与演化》杂志 11 日发表的一项生态学研究，一种在科学上被认为已消失的鹿类有蹄类动物，在越南野外被重新发现。此前，最后一次关于这种银背鼷鹿的记录是 1990 年被猎杀的一个标本，现在是研究人员在 30 年里首次拍到了活的银背鼷鹿。
