  • Anthropogenic disturbances and the dmergence of native diseases : a threat to forest health 
    Burgess, Treena, I.; Oliva, Jonas; Sapsford, Sarah J.; Sakalidis, Monique L.; Balocchi, Felipe; Paap, Trudy (Springer, 2022-06)
    PURPOSE OF REVIEW : Human-caused global change is fundamentally altering natural forest ecosystems. More trees are exhibiting a wide range of symptoms indicative of poor vigour, particularly stressed species at the edge ...
  • Botanical gardens provide valuable baseline Phytophthora diversity data 
    Hulbert, J.M. (Joey); Paap, Trudy; Burgess, Treena I.; Roets, Francois; Wingfield, Michael J. (Elsevier, 2019-12)
    Phytophthora species are important plant pathogens especially due to their ability to invade and change ecosystems. However, information regarding their diversity and distribution is not available in many parts of the ...
  • Cypress canker : an important disease discovered for the first time on a native South African tree 
    Wingfield, Michael J.; Marincowitz, Seonju; Pham, Nam Q.; Roets, Francois; Paap, Trudy; Wingfield, Brenda D.; Aylward, Janneke (Wiley, 2022-10)
    Cypress canker is a branch and stem canker disease of Cupressaceae trees, particularly those in the genera Cupressus and Hesperocyparis. These trees have been planted in many parts of the world as ornamentals and the ...
  • Harmonising the fields of invasion science and forest pathology 
    Paap, Trudy; Wingfield, Michael J.; Burgess, Treena I.; Hulbert, J.M. (Joey); Santini, Alberto (Pensoft Publishers, 2020-10-15)
    Invasive alien species are widely recognised as significant drivers of global environmental change, with far reaching ecological and socio-economic impacts. The trend of continuous increases in first records, with no ...

    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 ...
  • Two novel Phytophthora species from the southern tip of Africa 
    Bose, Tanay; Hulbert, J.M. (Joey); Burgess, Treena I.; Paap, Trudy; Roets, Francois; Wingfield, Michael J. (Springer, 2021-06)
