Fifth Webinar: 26 May 2021
Prof. Şerban Procheş: Global plant geography: Diversity patterns, kingdoms and biomes
(Talk starts at 4:50)
About the Speaker: Prof. Şerban Procheş
Şerban Procheş is Professor of Biogeography at the University of KwaZulu-Natal, Westville Campus. He hails from Bucharest, Romania, where he did his undergraduate and Masters studies, following on with a PhD at UKZN. Prof Procheş is particularly interested in ecological and evolutionary drivers of biogeography. He has explored such patterns across different taxa for South Africa with a special interest in the Cape Flora, but has also included other regions, both locally and globally. He has also published conceptual and applied research dealing with alien invasive plants.

Third Webinar 17 February
SAAB Best Young Scientist Awardee 2020: Zaynab Shaik
About the speaker: Zaynab Shaik
Zaynab Shaik won the ‘Best Young Botanist’ award at the 46th Annual SAAB conference at University of the Free State, QwaQwa Campus in January 2020 for her presentation about adding molecular data to the problem of species delimitation in plants. This follows on from her award for the Best MSc oral presentation (in systematics) at the 45th Annual SAAB, AMA and SASSB Joint congress in 2019. Her MSc was on ‘Species delimitation and speciation process in the slangbos, the Seriphium plumosum L. complex (Gnaphalieae, Asteraceae) in South Africa’, wherein she explored the hypothesis that this widespread, variable species houses multiple independent lineages. She applied an integrative taxonomic approach, combining evidence from next-gen sequencing, morphology, ecology and geographic distribution. Zaynab’s main interests are in plant molecular phylogenetics and systematics. She studied at UCT to Masters level, followed by an internship at SANBI Kirstenbosch. Zaynab is currently a junior lecturer in plant genomics at the University of Stellenbosch, and her PhD is based at Gothenburg University, Sweden, under the supervision of Prof. Bengt Oxelman (GU), Prof Tony Verboom (UCT) and Dr. Nicola Bergh (SANBI).

SAAB Silver medalist webinar: Prof Timm Hoffman
About the Speaker: Prof. Timm Hoffman- SAAB Silver medalist 2020
Timm Hoffman holds the Leslie Hill Chair in Plant Conservation in the Department of Biological Sciences at the University of Cape Town. After completing his PhD at UCT in 1989 he spent a post-doc at the Jornada Long Term Ecological Research program in New Mexico, USA before joining the South African National Biodiversity Institute in 1991. He led a national review of land degradation in South Africa which was published as a co-authored book in 2000. He has been at UCT since 2001 where he is the Director of the Plant Conservation Unit. Timm is interested in how southern African environments have changed over time primarily in response to land use and climate. He has a special interest in the arid parts of southern Africa and uses repeat photography to understand the nature, extent and rate of long-term vegetation change in the region. He takes an interdisciplinary approach to the study of environmental change and includes elements from the historical, anthropological and social sciences in his research. In recognition of the interdisciplinary nature of his contributions, especially in the communal areas of Namaqualand, Timm was the recipient of the WWF Living Planet Award in 2020. He also received the SAAB 2021 Silver Medal Award for his research and other contributions to the advancement of botany in South Africa.

First Webinar 20 January 2021:
SAAB Bronze medalist webinar: Dr Blair Cowie
About the speaker: Dr. Blair Cowie – SAAB Bronze Medalist 2020
Dr. Blair Cowie, our SAAB Bronze Medal winner for 2021, undertook his PhD studies at the University of the Witwatersrand from 2017 to 2020 under the supervision of Professors Ed Witkowski and Marcus Byrne. The focus of his study was the noxious “famine weed” Parthenium hysterophorus,one of South Africa’s most damaging invasive weeds, which threatens food security, our native biodiversity and hence human livelihoods and well-being. All of Blair’s undergraduate and postgraduate years were spent at Wits, where he developed a reputation for being an outstanding student. During his postgraduate years of study, Blair worked on a range of invasive alien plants in South Africa (Eichhornia crassipes, Lantana camara, Opuntia spp., Solanum mauritianum) – contributing to an understanding of their invasive ecology and assessing control programmes for them. Blair has also contributed to policy developing an integrated management strategy for the control of Solanum mauritianum (bugweed) in South Africa, and already published 12 articles in international journals and presented his work at many conferences, both local and international. Blair has also co-supervised two Honours students and helped numerous others during his time at Wits. He is currently a Post-Doctoral Researcher at the Centre for Biological Control in the Department of Zoology and Entomology at Rhodes University, Grahamstown, where he is continuing his work on invasive alien plants, namely the biological control of Mesquite (Prosopis spp.).
