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.

Scaena Theatre: Steel Magnolias
2007-08-22

Steel Magnolias

By: Robert Harling
Director: Elizna Pieters

With: Eileen van der Merwe, Nicole Smit, Nastacia de Klerk, Jenette Vivier, Isabel Mostert, Ilse Hancke

Steel Magnolias is a must-see production soon to be performed by drama students in their second year at the University of the Free State. It is directed by Elizna Pieters, currently doing her B.A. Drama and Theatre Arts (Hons) in directing.

The action is set in Truvy's beauty salon in Chinquapin, Louisiana, where all the ladies who are "anybody" come to have their hair done. Helped by her eager new assistant, Annelle (who is not sure whether or not she is still married), the outspoken, wise-cracking Truvy dispenses shampoos and free advice to the town's rich curmudgeon: Ouiser ("I'm not crazy, I've just been in a bad mood for forty years"), an eccentric millionaire; Miss Clairee, who has a raging sweet tooth; and the local social leader, M'Lynn, whose daughter, Shelby (the prettiest girl in town), is about to marry a "good ole boy”.

Although filled with hilarious repartee and verbal collisions, the play moves toward tragedy when the spunky Shelby, a diabetic, risks pregnancy. Soon the women realize that they share everything, from the shampoo and gossip right down to love, loss and an underlying strength. This gives the play and its characters, the special quality to make them truly touching, funny and marvelously amiable company in good times and bad.

Steel Magnolias can be seen at the Scaena Theatre on the UFS campus, on 11 and 13 September 2007 (English Production).

Ysterasters is te sien in die Sceana Teater (UV-kampus) op 12 en 14 September.  (Afrikaanse Produksie)
