The bii4africa dataset of faunal and floral population intactness estimates across Africa’s major land uses.
Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species’ population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate ‘intactness scores’: the remaining proportion of an ‘intact’ reference population... -

New combinations in and typification of tropical African species of Urochloa (incl. Brachiaria) (Poaceae).
Detailed morphological and molecular research has led to the conclusion that the majority of the species of the genus have to move to the much smaller genus . Although many of the necessary new combinations were made, in Africa a fair number of accepted species still do not yet have...Oulo, M. ; van der Zon, A.P.M. ; Sosef, M. S. M.

Phylogenomic inference of the African tribe Monodoreae (Annonaceae) and taxonomic revision of Dennettia, Uvariodendron and Uvariopsis.
Monodoreae (Annonaceae) is a tribe composed of 11 genera and 90 species restricted to the tropical African rain forests. All the genera are taxonomically well circumscribed except the species rich genera and which lack a recent taxonomic revision. Here, we used a robust phylogenomic approach, including all the 90 currently... -

Phylogeny and infrageneric classification of Clerodendrum (Lamiaceae).
The infrageneric classification of the genus Clerodendrum (Lamiaceae) has been highly problematic due to different concepts and subdivisions being applied to the treatment of Asian, Australian, and African species. Earlier molecular phylogenetic studies based on Sanger sequencing and limited sampling have indicated that previous morphology-based infrageneric classifications are not congruent... -

Cattle tick control in Africa: potential of ethnoveterinary plants.

Seasonal dynamics of Anopheles stephensi and its implications for mosquito detection and emergent malaria control in the Horn of Africa.
Invasion of the malaria vector across the Horn of Africa threatens control efforts across the continent, particularly in urban settings where the vector is able to proliferate. Malaria transmission is primarily determined by the abundance of dominant vectors, which often varies seasonally with rainfall. However, it remains unclear how abundance... -

The inclusion by Robinson (1999) of the earlier validly published Crystallopollen Steetz ([in Peters] 1864) as a synonym however, rendered Polydora Fenzl ex H.Rob.

Southern Africa as a ‘cradle of incense’ in wider African aromatherapy.
The modern paradigm of aromatherapy is based on in vitro assays of pure volatile organic compounds (as an essential oil), with activity at non-clinically significant concentrations. Yet traditional use of aromatic species did not involve pure essential oils because hydrodistillation was only invented in relatively recent times (estimated 1200 AD).... -
