The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...
