Ethnobotany in Angola: The contribution of late 19th century christian missionaries to the knowledge of medicinal wild plants.

Ethnopharmacological Relevance: Angola has an extraordinary plant diversity and a great ethnobotanical potential. However, there is a general lack of information about the first botanical explorations in the country and their contribution to the knowledge of the medicinal flora.

Aim Of The Study: The main aim of this study was to unveil the ethnobotanical legacy of José Maria Antunes and Eugène Dekindt, priests of the first Catholic mission in Huíla (Angola) and shed light on their contribution to the knowledge of medicinal wild plants of the country, including information on the uses, plant parts used, and preparation methods documented in the late 19th century.

Structural diversity and tree density drives variation in the biodiversity-ecosystem function relationship of woodlands and savannas.

Positive biodiversity-ecosystem function relationships (BEFRs) have been widely documented, but it is unclear if BEFRs should be expected in disturbance-driven systems. Disturbance may limit competition and niche differentiation, which are frequently posited to underlie BEFRs. We provide the first exploration of the relationship between tree species diversity and biomass, one measure of ecosystem function, across southern African woodlands and savannas, an ecological system rife with disturbance from fire, herbivores and humans.
