Her love of numbers and analysing data – to such an extent that she, just for the fun of it, did university Mathematics in her spare time in Grade 10. This not only resulted in an A for Maths in matric, but also contributed to Walena Anesu Marambakuyana’s success during her postgraduate studies, as she was announced the best honours student in her year group in the Faculty of Natural and Agricultural Sciences. 

Solutions to Africa’s challenges

For this prestigious achievement, she was presented the Dean’s Medal, which she collected during the faculty’s graduation ceremony on 21 April 2022. “I can't begin to say how much this means to me. I think of the struggles that I've faced, and it just proves to me that anything is possible if you set your mind to it,” says Walena, who believes this achievement will also motivate her little sisters to aim higher in life. 

Walena, who completed her undergraduate studies in Actuarial and Financial Mathematics at the University of Pretoria, continued with her honour’s degree in Risk Analysis at the UFS.

“Thinking back, it was always clear that I would take this route. Throughout primary school and high school, the Math teachers particularly liked me. I think it was because they saw that I really enjoyed Mathematics. I also remember that at the tender age of seven, my dad's colleagues would call me a mathematician,” recounts Walena.

She, like her aunt and role model, Dr C Gandidzanwa, is working towards obtaining a PhD. Currently, Walena is enrolled for the master’s degree in Risk Analysis at the UFS. “In my view, a PhD would enable me to contribute to innovative ideas that will provide solutions to the various challenges we are facing in Africa and the world at large. I specifically would like to inspire younger generations coming after us to safeguard against risks by anticipating, assessing, and taking the necessary steps to mitigate against risks,” she says.

“I believe risk assessment and mitigation not only contribute to my day-to-day activities; it also affects bigger global challenges such as climate change. Through my studies, I have a clear picture of what can be done to mitigate these risks. However, the challenge is always to ensure that this filters to practical action,” says Walena.

This is where I belong

Receiving the Dean’s Medal for the best marks in the group of master’s students in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS), was another mathematician, Elize Swartz. “Receiving the Dean's Medal is a great honour for me. It reminds me that hard work pays off and it encourages me to continue with my studies.”

She completed her honours degree, majoring in Mathematics and Applied Mathematics, in 2019 and her master’s degree in Mathematics in 2021. For both, her mini thesis was in the field of graph theory.

Currently a lecturer in the UFS Department of Mathematics and Applied Mathematics, she is looking forward to starting with her PhD later this year. Elize, who already knew in primary school that she wanted to be a teacher, is hoping to one day be a full-time lecturer at the UFS. “My passion is to work with young people. I hope to make a difference in their lives by teaching, sharing my knowledge, and helping them in such a way that they experience the love of Jesus Christ,” she says. 

She continues: “I cherish the instances when my lecturers gave me advice, encouraged me, and recognised my hard work. I want to share and continue that positive experience with other people and students by teaching them to work hard and be responsible, while treating them with kindness, patience, and love.”

Her favourite part of studying was the moment when she did homework and assignment problems and everything just started to fall into place. “For me, Maths problems are almost like a little game or puzzle. I also enjoyed receiving my marks after each assignment, test, or exam, knowing that this was the result of all my hard work,” says Elize, who also enjoys campus life, especially after the lockdown, “walking on campus – feeling safe, at home, and the sense of knowing this is where I belong”.

Stress and fear on wild animals examined

Have you ever wondered how our wild cousins deal with stress? Dr Kate Nowak, visiting postdoctoral researcher at the Zoology and Entomology Department at the UFS Qwaqwa Campus, has been assigned the task to find out. She is currently conducting research on the effects that stress and fear has on primate cognition.

The Primate and Predator project has been established over the last two years, following Dr Aliza le Roux’s (also at the Zoology and Entomology Department at Qwaqwa) interest in the effects of fear on primate cognition. Dr le Roux collaborates with Dr Russel Hill of Durham University (UK) at the Lajuma Research Centre in Limpopo and Dr Nowak has subsequently been brought in to conduct the study.

Research on humans and captive animals has indicated that stress can powerfully decrease individuals’ cognitive performance. Very little is known about the influence of stress and fear on the cognition of wild animals, though. Dr Nowak will examine the cognition of wild primates during actual risk posed by predators. This is known as the “landscape of fear” in her research.

“I feel very privileged to be living at Lajuma and on top of a mountain in the Soutpansberg Mountain Range. We are surrounded by nature – many different kinds of habitats including a tall mist-belt forest and a variety of wildlife which we see regularly, including samangos, chacma baboons and vervet monkeys, red duiker, rock hyrax, banded mongooses, crowned eagles, crested guinea fowl and cape batis. And of course those we don't see but find signs of, such as leopard, genet, civet and porcupine. Studying the behaviour of wild animals is a very special, and very humbling, experience, reminding us of the diversity of life of which humans are only a very small part,” said Dr Nowak.

At present, the research team is running Giving up Densities (GUD) experiments. This represents the process during which an animal forsakes a patch dense with food to forage at a different spot. The animal faces a trade-off between meeting energy demands and safety – making itself vulnerable to predators such as leopards and eagles. Dr le Roux said that, “researchers from the US and Europe are embracing cognitive ecology, revealing absolutely stunning facts about what animals can and can’t do. Hence, I don’t see why South Africans cannot do the same.”

Dr Nowak received the Claude Leon Fellowship for her project. Her research as a trustee of the foundation will increase the volume and quality of research output at the UFS and enhance the overall culture of research. Her analysis on the effect that stress and fear have on wild primates’ cognition will considerably inform the emerging field of cognitive ecology.

The field of cognitive ecology is relatively new. The term was coined in the 1990s by Les Real to bring together the fields of cognitive science and behavioural ecology.
