Cankers leading to branch, stem and plant death were observed on the South African endemic Rafnia
amplexicaulis (Fabaceae) in the Cederberg Wilderness Area, South Africa, during September 2021. Conidiomatal
pycnidia were ...
Knoxdaviesia and Sporothrix species occupy the flower heads of some Protea plants in southern Africa. Knoxdaviesia
species display exceptional genetic diversity within the Core Cape Subregion (CCR) and are readily
dispersed ...
A unique microbiome occurs within the flower heads of various Protea species endemic to
Africa. These include two lineages of ophiostomatoid fungi, Knoxdaviesia (Microascales) and
Sporothrix (Ophiostomatales), that have ...
The widely adopted use of metabarcoding techniques and the ability to sequence microbial
communities directly from environmental samples have advanced the field of fungal ecology.
The growth of publicly available big ...

The Namib Desert of south-western Africa is one of the oldest deserts in the world and possesses unique
geographical, biological and climatic features. While research through the last decade has generated a
comprehensive ...
Patterns and drivers of succession provide insight into the mechanisms that govern community assembly, but
remain poorly understood for microbial communities. We assess whether successional trends of trees are
mirrored ...
Dietary quality has significant implications for health, nutrition and life quality. Yet,
most people in developing countries, such as Malawi, consume inadequate diets
due to the high cost of healthy and nutritious food. ...
BACKGROUND : Multidrug-resistant extended-spectrum b-lactamase (ESBL)- producing Enterobacterales is regarded as a critical health issue, yet, surveillance in the water-plant-food interface remains low, especially in Africa. ...
An African Vice-Chancellors’ Regional Food Systems Dialogue was hosted with the aim to provide a multi-stakeholder platform for stakeholders to explore various existing and emerging approaches that have the potential to ...
Precise water management is imperative for sustainable crop production under
