The relative importance of natural and human-induced environmental conditions for species richness distribution patterns in South Africa
… species richness patterns in South Africa at the quarter-degree square (QDS) resolution, which is a phenomenon that has been either overlooked, or not completely clarified, in many previous studies of the same region and data at the same resolution. In particular, I investigated hypotheses that …

The importance of hydrologic refugia for the diversity of the Cape Flora
… correlates of these distributions. I make use of Quarter degree square grid cells as a measuring unit, which are larger (~20 km across), than the scale at which microrefugia typically occur, however, the broad environmental heterogeneity within these units provides a meaningful basis for …

Identification, mapping and ranking of important plant areas in Oshana, Oshikoto, Omusati and Ohangwena regions in Namibia
The identification of IPAs (Important Plant Areas) has been at the forefront of conservation research in recent years however, there is no recent information on the IPAs in Namibia. Thus, the aim of this study was to identify, map, and rank the IPAs in the study regions using the IPA criteria …

Endemism and richness in the Cape floristic region: phytogeographic patterns and environmental correlates in a global biodiversity hotspot
… elements. In the Combined Dataset, nearly all Quarter Degree Square (QDS) cells were assigned to PCs in the core CFR, indicating endemism is common throughout the CFR. However, endemic taxa were concentrated in the high winter rainfall west, and southwest areas. The large size of the dataset, …
