最新研究：人类活动影响动物迁移增加灭绝威胁
人类活动 动物迁移 灭绝威胁
2021/2/3
施普林格·自然旗下专业学术期刊《自然-生态与演化》最新发表一篇动物行为研究论文称，人类活动会影响动物在它们环境中的迁移方式，这会对动物的生命构成潜在风险，增加全球动物受到的灭绝威胁。该论文介绍，大部分人类活动会影响动物的迁移，无论是狩猎、旅游还是娱乐都会让动物避开特定区域。间接影响包括公路和城市、伐木和农业，这也会对栖息地造成干扰，迫使动物迁移到更远或更不适合它们的地方去寻找食物、栖息地或配偶。例...
澳大利亚巨型动物灭绝或由气候变化所致
澳大利亚 巨型动物 灭绝 气候变化
2020/5/22
澳大利亚多种巨型动物为何在4万年前灭绝一直是个未解之谜。日前，澳研究人员在英国《自然·通讯》杂志网站上发表论文称，最有可能导致澳大利亚巨型动物灭绝的原因是气候变化，而非人类活动。此前有观点认为巨型动物灭绝是人类过度狩猎造成的，且发生在人类抵达澳大利亚大陆后不久。但这项由澳大利亚昆士兰博物馆领导的研究结果显示，水资源减少、干旱加剧、火灾增加以及植被变化等最终导致袋狮、巨型史前袋鼠等至少13种远古巨兽...
