Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

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.

Interpreting implemented at UFS residences

2007-10-12

The University of the Free State (UFS) has begun to implement interpreting services at student residence meetings on the Main Campus in Bloemfontein, as part of the management of diversity and the racial integration of its residences.

As a pilot project, the interpreting services are being offered since the third term at Emily Hobhouse and Roosmaryn ladies residences, where a significant racial diversity already is present. From next year this service will be extended to all the student residences on the Main Campus.

The interpreting project is being managed by the Department of Afro-asiatic Studies, Sign Language and Language Practice at the UFS.

“Students in training at the Department of Afro-asiatic Studies, Sign Language and Language Practice and senior interpreters from the UFS are currently interpreting during residence meetings,” said Prof. Jackie Naudé, Departmental Chairperson of the UFS’s Department of Afro-asiatic Studies, Sign Language and Language Practice.

“Students in these residences are given the opportunity to be trained to interpret during their residence meetings. Four students from each hostel are being trained as interpreters,” said Prof. Naudé.

According to Prof. Naudé both residences have meetings that take place on a Monday evening at 22:00. Interpreting is also provided at the first-year students’ meetings at Emily Hobhouse on Tuesday evenings.

The interpreters experience the interpreting at the residences as positively and they experience that students often do utilise this service. At Roosmaryn 16-18 students are utilising the interpreting service, while at Emily Hobhouse approximately 18 students are utilising the service.

“The interpreting service definitely contributes to the enhancement of communication during residence meetings. Students can exactly follow what is happening during the meetings. In the past a residences like Emily Hobhouse tried to repeat everything in English, which extended the meetings,” Prof. Naudé said.

With the envisaged extension of interpreting services in hostel meetings to all the hostels on the Main Campus in Bloemfontein, there is a need for interpreters as these meetings will take place simultaneously. Through this initiative, exiting new opportunities are created for aspiring interpreters. The training takes place under leadership of Prof. Annelie Lotriet who holds the ATKV Chair in Interpreting in the department.

Aspiring candidates can contact Mr Cobus Snyman, Manager of the UFS’s interpreting projects at 051 401 9005 in connection with the selection criteria for interpreters.
