• Broad- and fine-scale vegetation patterns in the Waterberg, South Africa 

  Venter, Tamryn S. (University of Pretoria, 2022)

  Natural areas are under threat due to land transformation, placing additional pressure on existing protected areas and emphasizing the need for more conserved areas. However, effective conservation planning requires ...
• The role of dispersal mechanisms in range shifts of plant species across sub-Antarctic Marion Island 

  Mazibuko, Nompilo (University of Pretoria, 2022-09)
