The ghosts of forests past and future: deforestation and botanical sampling in the Brazilian Amazon

Ecography, Volume 43, Issue 7, Page 979-989, July 2020., 2020
The remarkable biodiversity of the Brazilian Amazon is poorly documented and threatened by deforestation. When undocumented areas become deforested, in addition to losing the fauna and flora, we lose the opportunity to know which unique species had occupied a habitat.
