Bold and fearless - Prof Aliza le Roux.

Prof Aliza le Roux is Associate Professor in Zoology and Entomology, and Assistant Dean in the Faculty of Natural and Agricultural Sciences on the UFS Qwaqwa Campus. 

A researcher at heart, and with a passion for researching wild mammals, small carnivores, and primates, Prof Le Roux says she is extremely curious and loves to know about a lot of different things.

I decided that I wanted to do something with wildlife, so I completed a BSc degree at Stellenbosch University. One day a professor said: “I just got back from doing research – we were catching lizards along the Orange River” – and I remember thinking, ‘yes, I can see that as my life’. Research is a fantastic career for anyone with curiosity and perseverance. You must have a good dose of bull-headed persistence. We all have the baseline intelligence, but anyone who has studied up to PhD will tell you that it is the persistence that carries you through.

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

What drew me into a career in research was Dian Fossey, an American researcher who was known for undertaking an extensive study of mountain gorilla groups. She had the guts to go out there and be there in the wilderness as the only woman there, doing stuff under extremely difficult conditions. 

Recently, it will be Simone Biles – she does the most mind-blowing stuff with gymnastics – who said she could not go forward with competing in the Olympics because of health reasons. I cannot imagine what guts it takes to say no at such a high-profile sporting event. The ability to say no is something that few of us possess, so right now she is a person I would love to celebrate. I am inspired by women who have the guts and the fact that you believe enough in yourself to do something, despite what others might have to say about it. 

What is your response to current challenges faced by women and available platforms for women development?
There is never enough support or platforms available for the development of women while you have domestic violence and GBV at such insane rates in this country. It’s still a women’s problem, whereas its men perpetrating this and women implicitly supporting it in the way we raise young men and respond to things such as rape accusations. 

It’s a societal problem, and I personally will not be happy until I see this changing in the country. You can look at the massive inequalities and gender biases and the things that are stacked against women, and then feel overwhelmed and step back and say this is too big a problem, I can’t do anything about it. You might not be able to tackle the big problem, but you can chip away at it. Everybody must contribute in a small way. 

What advice would you give to the 15-year-old you?

Be bold. Be fearless. I slowly started becoming like that at that age, but I could have started earlier. I should have told her I was gay; that would have helped. 

What would you say makes you a woman of quality, impact, and care?

There’s a healthy dose of guts and believing in yourself – that is the only way to make an impact. You cannot make an impact if you are doubting your own value, and this is difficult, because we are raised in many instances to be meek, raised to not be leaders but followers, and it’s difficult to overcome that and realise that you are bringing something unique to this world. 

The university is taking some very good steps with the mentorship programmes that it supports. But I would love to see more mentorship for students. Young men and young women in our care being inspired to talk and rethink how they treat women and what equality really means. We need to create more reflective people.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
