In vitro callus initiation of a ‘threatened’ Nigerian leafy vegetable, Gnetum africanum (WILW)
Gnetum africanum is a green leafy vegetable found in Nigeria, where it is a highly valued food source. Stocks of this plant in the wild are increasingly threatened by land transformation and harvesting methods are unsustainable. In vitro callus initiation of G. africanum has been developed.

Local extinctions of white-lipped peccary, due to habitat fragmentation and hunting, have been reported throughout its vast geographical range. Recent studies have shown that their role as fruit predators and dispersers affects the biodiversity of certain forest habitats. Fruits may be reduced in deforested habitats, so documenting fruit availability and use is critical to peccary conservation efforts...
