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.

Wag-’n-Bietjie, Vishuis and Sonnedou the winners at athletics

Six out of six.

This is the proud record Wag-’n-Bietjie can boast of after the residence walked away with the women's athletics trophy for the sixth year in a row during the University of the Free State's first-year athletics meeting.

This year's men's winner, Vishuis, attained a hat trick on 20 January 2016 at Pellies Park on the Bloemfontein Campus when the residence was once again named as the athletics champion. Vishuis also won in 2014 and 2015.

What makes Wag-’n-Bietjie's triumph even more remarkable is the fact that the residence ran the fastest, jumped and threw the farthest in eight out of the past nine years. Marjolein won in 2010.

Sonnedou was second, with Roosmaryn and Soetdoring collectively the third women's residences. In the men's division, Legatum and Armentum were second and third respectively.

Sonnedou has the best spirit

The event, a celebration of colour and fun, was characterised by groups of singing first-years yelling their lungs out. The UFS Student Representative Council judges the winners of the different Spirit trophies.

Sonnedou was the overall winner of the Spirit trophy – something even more important than the action on and around the track for some residences.

Sonnedou was named the winner in the division for women's residences, after which the residence was also crowned as overall winner. Welwitschia and Vergeet-My-Nie were second and third respectively in the women's division.

In the men's division, Armentum, who continued singing even when it was raining later in the evening, was the well-deserved winner of the Spirit trophy. Villa Bravado was second with Tswelopele third.

Conlaurês won the Spirit trophy for Co-ed residences, with Imperium and Kagiso second and third respectively.

Wayde a special guest

The Kovsie athlete, Wayde van Niekerk, who also participated in the first-year athletics meeting in his day, was a special guest.

The 400 m athlete, who will represent South Africa at the 2016 Olympics in Rio de Janeiro, was presented to the first-years during the official welcoming ceremony.

Van Niekerk is still the Kovsie record holder in some events, including the 200 m and the 400 m, as well as the 4 x 100 m team relay event.

Team and individual results for the event.
