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 Doctors make History in South Africa
2011-07-14

 

New aortic valve

Three members of our Faculty of Health Sciences made history by being the first to implant a special new aortic valve in South Africa. 
 
In a combined effort, the Departments of Cardiology, Pediatric Cardiology and Cardiothoracic Surgery did the first Medtronic CoreValve implant in South Africa on a patient in Universitas Academic Hospital. 
 
With the support of hospital management and the Medtronic company, Prof. Hennie Theron, Prof. Stephen Brown and Dr JP Theron of the Faculty of Health Sciences, with the assistance of Dr Jean-Claude Laborde, performed the operation early on Wednesday morning, 06 July 2011.
 
The advantage of this new valve is that it can be implanted percutaneously through a catheter from the groin. This eliminates the need for invasive surgery.
 
The valve is made from porcine pericardium (tissue derived from pigs) and is mounted on an expandable stent, which is threaded along an artery, until it reaches its desired position. Prof. Theron says the valve is especially useful in older patients who suffer from aortic valve disease and pose a high surgical risk. Furthermore, the use of this valve greatly reduces hospitalisation time, in comparison to traditional surgery.
 
“One patient already received an implant this morning and we hope to finish 2 more today,” Prof. Brown said, emphasizing the swiftness and efficiency of the new valve implanting process.
 
“It is a complex procedure, but this service can in future be offered to all patients in the public and private sectors of the Free State. It is heartwarming that the academic complex can take the lead in this modern, high-tech therapy.”
 
For more information on the procedure, please contact Prof. Theron at 051 4053428.
