Researchers have found that small mammal communities today are fundamentally different from even a few centuries ago, during North America's pre-colonial past. They identified small mammal remains from the Anthropocene and archaeological Holocene along a geographical area with varying degrees of human impact and examined diversity across these sites and time periods. Optimistically, the researchers also found that even small, protected spaces can conserve native small mammal communities, highlighting their important role in urban conservation projects.
