ABSTRACT Baobabs are of conservation concern in protected areas in southern Africa because rates of elephant‐induced mortality, coupled with severe drought periods, may threaten to lead to local extirpation. Alternatively, baobabs may persist because of spatial refuges provided by distance from permanent water or rugged topography.

Manganese oxide (MnO NPs), synthesis of Moringa oleifera leaf extract nanoparticles, are spherical and crystalline with a size of 8.3 nm. They exhibit strong antioxidant activity in DPPH and ABTS assays, with IC50 values of 9.08 and 6.62 µg/mL, respectively, and demonstrate low toxicity to kidney and liver cells.

Africa's plant diversity remains under‐documented due to limited sampling, expertise and resources, with type specimens offering a historical baseline to evaluate taxonomic effort and biodiversity knowledge. Using generalised linear modelling, we show that collection patterns in Mozambique were shaped by elevation, slope, land cover and accessibility ...

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere
Abstract Most published global and regional shear‐wave (VS ${V}_{\mathrm{S}}$) velocity models of cratons include a VS ${V}_{\mathrm{S}}$ increase with depth below the Moho, with a maximum at 100–150 km depth. This feature has long been debated, as it appears to require either (implausible) temperature decreases with depth, or substantial, layered ...

Identifying effective approaches to measuring habitat requirements for elusive and difficult‐to‐study species is an important component of ecological research, particularly for species of conservation concern. The continued decline of critically endangered White‐backed vultures (WbVs) Gyps africanus calls for urgent intervention and an increased ...

Exploring the complexities of cooperative breeding: insights from African wild dog packs
Across 14 years of monitoring African wild dog packs in Savé Valley Conservancy, Zimbabwe, we found that younger and larger packs were significantly more likely to produce multiple litters, with second‐born pups showing higher survival. Pup survival also increased with pack size, rainfall, and alpha female age, highlighting the adaptive benefits of ...

Summary Myrothamnus flabellifolia is a dioecious resurrection plant endemic to southern Africa that has become an important model for understanding desiccation tolerance. Despite its ecological and medicinal significance, genomic and transcriptomic resources for the species are limited.
