过去5万年哺乳动物生物多样性丧失的全球模式。近几个世纪以来，野生哺乳动物经历了大量的数量减少和灭绝，但它们的群落在更新世期间已经遭受了广泛的损失。现有的文献集中于记录个体灭绝或大陆尺度的模式。这个项目旨在展示生物多样性的丧失是如何在世界各地的地方范围内发生的。它将使用古生物学和动物考古学的数据来显示损失在空间上是如何变化的，种群规模是如何变化的，以及物种属性如稀缺性和体型是如何与损失相关的。随着生物多样性的下降，哺乳动物的世界变得更加同质化。我们面临的挑战是要证明这是如何跨越时空发生的

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