After the mammoths: The ecological legacy of late Pleistocene megafauna extinctions.
Camb Prism Extinct
February 2023
The significant extinctions in Earth history have largely been unpredictable in terms of what species perish and what traits make species susceptible. The extinctions occurring during the late Pleistocene are unusual in this regard, because they were strongly size-selective and targeted exclusively large-bodied animals (i.e.

The conservation status of large-bodied mammals is dire. Their decline has serious consequences because they have unique ecological roles not replicated by smaller-bodied animals. Here, we use the fossil record of the megafauna extinction at the terminal Pleistocene to explore the consequences of past biodiversity loss.

Article Synopsis
- Large wild mammals, called "megamammals," are in danger and their decline is a big concern for nature and the environment.
- These megamammals play an important role in keeping ecosystems healthy by affecting plants and other animals.
- When these large animals disappear, it can increase methane emissions, which are gases that contribute to climate change, more than we thought before.
