WomenofKovsies Dr Lize Joubert on flowers and their favourite insects
Pollination is important to maintain diversity in our natural ecosystem and maintain ecosystem health

“Pollination is important to maintain diversity in our natural ecosystem and maintain ecosystem health.” So says Dr Lize Joubert, lecturer in the Department of Plant Sciences at the University of the Free State. “Research helps to understand the interaction between insects and flowers and their many implications on real-world problems.”

Plant systematics and pollination biology, Dr Joubert’s research field, looks at how plants diversify, adapt to environmental changes and how their flowers evolve to keep attracting insects to pollinate them for reproduction. 

Dependency on pollination

Crop production is, in many cases, dependent on pollination. About 75% of the world’s crops are to some extent dependant on pollination. “Pollination is really important for us as human beings, but it is also important to maintain diversity in our natural ecosystem and maintain ecosystem health.”

Dr Joubert obtained her PhD in plant systematics in 2013 and was subsequently awarded the EM van Zinderen-Bakker Prize for an outstanding PhD dissertation in Botany.

She is also the curator of the Geo Potts Herbarium in Bloemfontein, the internationally accredited herbarium housing over 30 000 plant specimens, mainly representing the flora of central South Africa and several special collections from Marion Island, the Okavango Delta, and KwaZulu-Natal. 

Learning from the experts

As a young researcher Dr Joubert became part of the Prestige Scholars Programme (PSP) at the UFS which led her to Cambridge University where she became part of a research group for nearly two years under an expert in her field, Prof Beverley Glover. The PSP at UFS identifies and promotes promising young academics at the university to become full professors with excellent research accomplishments. 

Dr Joubert views the PSP Programme to a large extent as her academic home. She is proud to be part of the programme that has brought her closer to other experts in her field and resulted in collaborations in which she is involved in cutting-edge research.

New yeast named after Bloemfontein

A second living organism was named after Bloemfontein, adding to the fact that the University of the Free State (UFS) has the largest yeast collection in the Southern Hemisphere.

In an article in the highly acclaimed scientific journal, International Journal of Systematic and Evolutionary Microbiology, three lecturers from the Department of Microbial, Biochemical and Food Biotechnology, at the UFS, Dr Carlien Pohl, Prof. Martie Smit and Prof. Jacobus Albertyn, describe four new yeast species.
 
One of these species, isolated from pine needles from Bloemfontein, has been named after this city and will be known as Rhodotorula bloemfonteinensis. ‘Rhodo’ refers to the redness of these types of yeast. This makes this yeast only the second living organism to be named after Bloemfontein. The other is a mite (Pilogalumna bloemfonteinensis), which was described in 1972.
 
In short, yeast is a micro-organism that is part of the fungi family. Prof. Albertyn, “The most common of these are the bakers’ yeast, of which the bloemfonteinensis forms part.”
 
Among these four species they discovered, the Rhodotorula pini was also discovered on the Bloemfontein Campus of the UFS during December 1995.
 
“The UFS now has the largest yeast collection in the Southern Hemisphere. All over the world, science is busy researching the field of bio-diversity. This promotes the bio-diversity at the UFS,” Prof. Albertyn says.
