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.

How are children taught about sexuality?
2014-01-05

 

Prof Dennis Francis
How is sexuality taught at schools? More importantly, why is heteronormativity taught at schools?

These are the questions that drive Prof Dennis Francis, Dean of the Faculty of Eduation, in his research on sexuality education.

His extensive research papers point out how schools promote compulsory heterosexuality and that homosexuality is something to be hidden and kept separate from teaching, learning and daily school life.

Prof Francis’ research dates back to the early 2000s, when he became concerned about the high HIV prevalence and other sexually transmitted diseases among 15-25-year-olds and the dropping age of sexual debut, as well as the increase of sexually active teenagers that are not adequately protecting themselves against undesired pregnancies and disease.

It was in the light of this that he started looking at how messages of sex and sexuality were conveyed to adolescents before becoming sexually active.

From 2006 to 2008, he was awarded a Medical Research Council Grant under the MRC research priority area of HIV/Aids.

In the past three years, he has collaborated with Dr Renee de Palma, a leading international European scholar who has published widely on sexuality education, gender and heteronormativity.

Using a National Research Foundation (NRF) grant, they collected data from 25 sexuality educators across the Free State on the teaching of sexuality education. They have published three articles in peer-reviewed journals, one is in press, one book chapter was published and two are currently under review.

Prof Francis says he is also pursuing a research project in the teaching of lesbian, gay, bisexual and transgender education in the sexuality education curriculum.
