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.

UFS team helps a pupil to hear again
2014-01-24

 

“I was scared at first. I could not remember the sound of my own voice. Being Deaf -it was like living on another planet.”

These are the words of the 18-year-old Andile (Godfrey) Jantjies after he heard sounds and words for the first time in almost 12 months.

Andile, a former pupil at the Albert Moroka School in Thaba Nchu, was the recipient of a cochlear implantation under the Bloemfontein Cochlear Implant Programme (BCIP) run by the Department of Otorhinolaryngology at the University of the Free State.

Andile lost his hearing after contracting bacterial meningitis in June 2013. This resulted in bilateral profound deafness and despite his good academic record, his school refused to have him enrolled for 2014.

The cochlear implant was inserted in October 2013 and was switched on for the first time on Thursday 23 January 2014.

“I want to go back immediately,” Andile said excitedly after gradually becoming comfortable with hearing his own and other voices.

Dr Iain Butler from the Department of Otorhinolaryngology says cases like Andile’s are a medical emergencies due to the fact that meningitis causes the inner ear to become replaced by bone.

“This can occur after as little as four months after the infection and means that the insertion of a cochlear implant becomes impossible.

A cochlear implant system costs approximately R220 000.

It converts sounds/speech into electrical signals that directly stimulate the auditory nerve, bypassing the damaged inner ear. It is indicated for babies with congenital hearing loss, as well as acquired hearing loss in children or adults. It requires intensive rehabilitation in order to learn to hear again, and most recipients develop very good hearing. Andile now has the opportunity to hear again, continue his schooling and become an economically independent member of society, rather than being dependent on others.
