  • Biogeographical survey of soil microbiomes across sub-Saharan Africa : structure, drivers, and predicted climate-driven changes 
    Cowan, Don A.; Lebre, Pedro H.; Amon, C.E.R.; Becker, R.W.; Boga, H.I.; Boulange, A.; Chiyaka, T.L.; Coetzee, T.; De Jager, Pieter Christiaan; Dikinya, O.; Eckardt, F.; Greve, Michelle; Harris, Mathew Andrew; Hopkins, D.W.; Houngnandan, H.B.; Houngnandan, P.; Jordaan, K.; Kaimoyo, E.; Kambura, A.K.; Kamgan Nkuekam, Gilbert; Makhalanyane, Thulani P.; Maggs‑Kolling, G.; Marais, E.; Mondlane, H.; Nghalipo, E.; Olivier, Bernard Wilhelm; Ortiz, M.; Pertierra, Luis R.; Ramond, Jean-Baptiste; Seely, M.; Sithole‑Niang, I.; Valverde, Angel; Varliero, Gilda; Vikram, Surendra; Wall, D.H.; Zeze, A. (BMC, 2022-08-23)
    BACKGROUND : Top-soil microbiomes make a vital contribution to the Earth’s ecology and harbor an extraordinarily high biodiversity. They are also key players in many ecosystem services, particularly in arid regions of the ...
  • Differences in bacterial diversity, composition and function due to long-term agriculture in soils in the Eastern Free State of South Africa 
    Dube, Joel Prince; Valverde, Angel; Steyn, J.M. (Joachim Marthinus), 1963-; Cowan, Don A. (MDPI, 2019-04-17)
    Land-use change from natural to managed agricultural ecosystems significantly impacts soil bacterial diversity and function. The Eastern Free State (EFS) is one of the most productive agricultural regions in South Africa. ...
  • Diversity and seasonality of fungal communities in soil from the Succulent Karoo biodiversity hotspot, South Africa 
    Pieterse, Zelda; Aveling, T.A.S. (Terry); Jacobs, Adriana; Cowan, Don A. (Elsevier, 2020-01)
    The fungal rhizosphere communities associated with soil surrounding Aizoaceae plants in the Namaqua National Park in the Succulent Karoo biodiversity hotspot, South Africa, were analysed by culture-dependent and ...
  • The functional potential of the rhizospheric microbiome of an invasive tree species, Acacia dealbata 
    Kamutando, Casper N.; Vikram, Surendra; Makhalanyane, Thulani P.; Greve, Michelle; Le Roux, Johannes J.; Richardson, David M.; Cowan, Don A.; Valverde, Angel (Springer, 2019-01)
    Plant-microbe interactions mediate both the invasiveness of introduced plant species and the impacts that they have in invaded ecosystems. Although the phylogenetic composition of the rhizospheric microbiome of Acacia ...
  • New and interesting fungi. 4 
    Crous, Pedro W.; Hernandez-Restrepo, H.; Schumacher, R.K.; Cowan, Don A.; Maggs-Kolling, G.; Marais, E.; Wingfield, Michael J.; Yilmaz, Neriman; Adan, O.C.G.; Akulov, A.; Alvarez Duarte, E.; Berraf-Tebbal, A.; Bulgakov, T.S.; Carnegie, A.J.; De Beer, Z. Wilhelm; Decock, C.; Dijksterhuis, J.; Duong, Tuan A.; Eichmeier, A.; Hien, L.T.; Houbraken, J.A.M.P.; Khanh, T.N.; Liem, N.V.; Lombard, L.; Lutzoni, F.M.; Miadlikowska, J.M.; Nel, Wilma Janine; Pascoe, I.G.; Roets, F.; Roux, Jolanda; Samson, R.A.; Shen, M.; Spetik, M.; Thangavel, R.; Thanh, H.M.; Thao, L.D.; Van Nieuwenhuijzen, E.J.; Zhang, J.Q.; Zhang, Y.; Zhao, L.L.; Groenewald, Johannes Zacharias (Westerdijk Fungal Biodiversity Institute, 2021-04-28)
    An order, family and genus are validated, seven new genera, 35 new species, two new combinations, two epitypes, two lectotypes, and 17 interesting new host and / or geographical records are introduced in this study. Validated ...
  • Seasonal variability in fungal endophytes from Aizoaceae plants in the Succulent Karoo biodiversity hotspot, South Africa 
    Pieterse, Zelda; Aveling, T.A.S. (Terry); Jacobs, Adriaana; Cowan, Don A. (Elsevier, 2018-05)
    All ten species of Aizoaceae screened in this study were populated with endophytes. Fifty nine fungal species from 25 genera, including fourteen rare species, were identified. Seasonal specificity was observed; with 32 and ...
  • Soil nutritional status and biogeography influence rhizosphere microbial communities associated with the invasive tree Acacia dealbata 
    Kamutando, Casper N.; Vikram, Surendra; Kamgan-Nkuekam, Gilbert; Makhalanyane, Thulani P.; Greve, Michelle; Le Roux, Johannes J.; Richardson, David M.; Cowan, Don A.; Valverde, Angel (Nature Publishing Group, 2017-07-26)
    Invasiveness and the impacts of introduced plants are known to be mediated by plant-microbe interactions. Yet, the microbial communities associated with invasive plants are generally poorly understood. Here we report on ...
  • Temporal shifts of fungal communities in the rhizosphere and on tubers in potato fields 
    Zimudzi, Josephine; Van der Waals, Jacqueline Elise; Coutinho, Teresa A.; Cowan, Don A.; Valverde, Angel (Elsevier, 2018-06)
    Soil fungal communities perform important ecological roles determining, at least in part, agricultural productivity. This study aimed at examining the fungal community dynamics in the potato rhizosphere across different ...
