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.

Study on school violence shows the secondary school environment compels learners to be armed
2015-01-26

The secondary school environment apparently compels learners to come to school armed. This is according to a study done by Dr Lynette Jacobs, a lecturer at the School of Education Studies at the University of the Free State.

In her study, Dr Jacobs found that learners from more affluent schools carry noticeably more weapons than learners in less affluent schools. Learners in the lower grades of secondary schools also use and carry more weapons than learners in the higher grades.

Dr Jacobs says while many reasons for school violence can be noted, such as to forcibly take the victims money and food, racial differences, religious differences, as well as the immigrant status of one of the parties involved, these were reasons indicated by less than 10% of the participants in the study.

“There is no single explanation for the threat of violence at schools and most acts of school violence appear to happen randomly, often out of instant retaliation.”

For the study, Dr Jacobs did surveys at schools across three provinces in South Africa.

“Although it varies in levels of seriousness, incidences of physical violence and verbal cruelty consistently occur at South Africans schools. I found that learners are furthermore regularly mocked, insulted, cursed and humiliated by peers.”
