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.

SRC and student parliament elections declared free and fair

2004-08-17

The Electoral Institute of Southern Africa (EISA) has certified the University of the Free State ’s (UFS) election process today ( Friday 13 August 2004 ) and declared it free and fair.

The process to elect a Student Representative Council (SRC) and Student Parliament started on 2 August 2004 and ended today with the announcement of the results.

“No objections regarding the voting process were received and the preliminary results were announced last night. A total of 2192 votes were cast, while 416 votes were spoilt,” said Mr Seth Phamuli, Chief Electoral Officer (CEO) of EISA.

Mr Alfred Geldenhuys, third year student in B Com Human Resource Management, was declared the SRC President for 2004/2005. Mr Geldenhuys was SRC representative for Campus Matters in 2003/2004.

The other members of the SRC are:

Vice-President: Annelise de Kock (fourth year student in B Sc Dietetics)

Secretary: Michelle du Plessis (third year student in B Sc)

Treasurer: Dida Coetzer (third year student in B Rek)

Academics: Cherese Laubscher (third year student in MB Ch B)

Ladies Internal Liaison: Tanya de Jager (third year student in B Ed Intermediary Phase)

Men’s Internal Liaison: Stef Conradie (third year student in BA Human Movement Science)

Transformation: Clayton van der Ross (second year student in B Com Human Resources Management)

Arts and Culture: AC Geldenhuys (second year student in B Acc)

Recreation and Internal

Affairs: Khotso Motloung (third year student in B Com Accounting)

Campus Services: Sylvanus Watson (fourth year student in B Sc Agric)

Constitutional and

Legal Affairs: Lerato Mofoti (fourth year student in LLB)

Dialogue and

Associations: Owen Kumalo (third year student in B Com Sport Management)

Kovscom: Estel Scheepers (third year student in BA Integrated Marketing)

Sport: Graeme Bradley (second year student in B Com Human Resources Management)

Student Development: Werner du Preez (third year student in B Com Economics)

Irawa: Jeanri-Tine van Zyl (second year student in BA Media Studies)

In the Student Parliament the African Christian Democratic Party (ACDP) and the Kovsie Alliance were each granted seven seats, whilst the Here XVII was granted 11 seats.
