Dr Katlego Mashiane
Striving to make a difference in the field of biodiversity conservation, Dr Katlego Mashiane decided to pursue a PhD in Geography, focusing on the spatial modelling of grassland diversity and nutrients in subalpine environments. He received his PhD during the recent April graduation ceremonies on the Qwaqwa Campus.

In the small village of Ga-Mabotia about 25 km outside of Polokwane, Dr Katlego Mashiane grew up, surrounded by rocky mountains characterised by boulder outcrops, where he interacted with nature from an early age. 

He recently obtained his PhD, majoring in Geography, from the University of the Free State (UFS), which was conferred on him during the April graduation ceremonies that took place on the UFS Qwaqwa Campus. The title of his dissertation is Grass nutrients estimation as an Indicator of rangeland quality using satellite remote.

Predicting the presence of biodiversity and nutrients in an area

Based on the principle that diverse grasslands tend to perform better, environmental changes threaten the resilience and services these grassland ecosystems provide. The study examined how many different types of plants and animals can be found at a particular place to enhance our understanding of the ecosystem’s value to humans, and that biodiversity loss will reduce these ecosystem services. Focusing on spatial modelling of grassland diversity, Dr Mashiane specifically investigated the influence of topography and remotely sensed satellite data on species richness and diversity in subalpine environments, and how they are affected by the availability of grass species. To determine this, he used a random forest machine-learning algorithm to find the best information in the data that could be used to estimate the levels of species richness, diversity, and nitrogen in a protected national conservation park. 

His study discovered that some data types – such as the near-infrared variable and certain vegetation data (EVI and SAVI) – were especially useful for determining the number and variety of species in a certain area. With this information, scientists can create models that predict the presence of different types of biodiversity and nutrients in an area.

Playing a key role in protecting our natural assets

Equipped with this knowledge, one will be able to understand how to protect and preserve different types of biodiversity and promote the nutritional value of both plants and animals in the environment. “Land managers could use this information for conservation strategies,” states Dr Mashiane, who decided to pursue this study because he was curious about how environmental changes will affect species.

“Grasslands provide important ecosystem services underpinning human well-being, and therefore warrant our protection; I would like to play a role in protecting our natural assets and contribute to understanding our biomes, especially in the context of global change,” he says.

In the next five years, Dr Mashiane plans to pursue further research and mentor other students in his field of study.

Soetdoring/Kagiso pair-up wins 2015 Stagedoor
2015-03-03

With a new format and residences mixing it up, the 2015 Stagedoor proved to be a success yet again, leaving Soetdoring and Kagiso with the spoils of victory.

Stagedoor (the annual first-year residence stage and serenade competition) saw a change of format this year where residences were combined to perform in a few number of outdoor venues for rotations.

Prior to this, Residence CoRC Cultures expressed much concern regarding the co-operation that might (or might not) be achieved with working with other residences. These were all early stage fears. However, as their preparations progressed there seemed to be a glint of light at the end of many groups’ tunnels.

Seven diverse and combined groups made it through to final, namely;

• Vishuis and Tswelopele,
• Karee and Armentum,
• Sonnedou and NJ van der Merwe,
• Soetdoring and Kagiso,
• Roosmaryn and Vergeert-My-Nie,
• Villa Bravado and Madelief, and
• and Veritas and Marjolein.

The finals proved that the efforts and sleepless nights of RC Cultures, first-years, composers, and other behind-the-scenes contributors can really make any situation work.

As always, the crowd was blown away by the musical and vocal talent of first-years, as some compositions gave the audience goose bumps, leaving them asking for more. All in all, the evening created a frenzy, causing residences to interact whereas they would have never done so before.

According to the Student Affairs’ Arts and Culture office, the aim behind the new format was to break the barriers between residences. Arts and Culture were also pleased as to with how the RCs worked around accommodating their partners and ensuring maximum co-operation, despite some challenges.

As the night neared its closeclosing, residences were chanting their names and showing their pride in their first years’ performances.

2015 Stagedoor final results:

1. Soetdoring and Kagiso
2. Roosmaryn and Vergeet-My-Nie
3. Vishuis and Tswelopele
