Global patterns of mammalian biodiversity loss over the last 50,000 years

近几个世纪来，野生哺乳动物经历了重大的人口损失和灭绝，但它们的社区在更新世已经遭受了广泛的损失。现有的文献集中在记录个别的预防或大陆规模的模式。该项目旨在展示生物多样性的丧失在世界各地的地方规模上是如何发生的。它将使用古生物学和动物考古学数据来显示损失如何在空间上变化，种群规模如何变化，以及物种属性（如稀有性和体型）如何与损失相关。随着生物多样性的下降，哺乳动物的世界变得更加同质化。挑战在于展示这是如何在时空中发生的。

Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeological data to show how losses varied in space, how population sizes changed, and how species attributes such as rarity and body size related to loss. The world of mammals has become more homogeneous as biodiversity has declined. The challenge is to show how that happened across space and time.
