Extinction risks of Amazonian plant species [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
Estimates of the number, and preferably the identity, of species that will be threatened by land-use change and habitat loss are an invaluable tool for setting conservation priorities. Here, we use collections data and ecoregion maps to generate spatially explicit distributions for more than 40,000 vascular plant species from the Amazon basin ...

Domestication of the Amazonian fruit tree cupuaçu may have stretched over the past 8000 years

open access: yesCommunications Earth & Environment, 2023
Amazonia, one of the largest and most biodiverse ecosystems on Earth, is a significant yet less-known arena for ancient plant domestication. Here, we traced the origins of cupuaçu (Theobroma grandiflorum), an Amazonian tree crop closely related to cacao (
