What to know about Genetic analysis reveals new species of endangered baobab tree in Madagascar

Researchers from UW-Madison and other institutions have identified a new species of endangered baobab tree in Madagascar, Adansonia bozy, using genetic analysis. The study, published in the journal Taxon, suggests that this reclassification may impact conservation funding and the status of other baobab species on the island.
