Five of the multidisciplinary team of researchers and some postgraduate students are determining the depth of soil on the underlying rock layer of the sodic site in the Kruger National Park.

When the Vice-Rector: Research, Prof Corli Witthuhn, invited researchers to apply for funding towards multidisciplinary and interdepartmental projects in 2015, Prof Piet le Roux from the Institute for Groundwater Studies, and the late Dr Fred Kruger from the Centre for Environmental Management took the opportunity and proposed a project to study a catenal ecosystem in the Kruger National Park

According to Dr Beanélri Janecke from the Department of Animal, Wildlife and Grassland Sciences, who led the research team on this project, the team of researchers worked for four years, finding links between the catenal ecosystem (which can be described as a hillslope with different zones forming an environmental gradient from crest to foothill) and processes behind some of its abiotic (non-living) and biotic (living) components. 

Large-scale multidisciplinary research project

All their research on this multidisciplinary project was published in one Special Issue of the Koedoe journal at the end of October 2020. Dr Janecke and Prof Johan van Tol from the Department of Soil, Crop and Climate Sciences were guest editors of this special issue. Dr Llewellyn Foxcroft from SANParks is the Editor-in-Chief of the journal. Other UFS departments involved in this project include the Departments of Genetics; Microbial, Biochemical and Food Biotechnology; Plant Sciences; and Zoology and Entomology.

Dr Janecke says there are 12 articles in this issue and, together with the principal researchers (but excluding postgraduate students), there were 12 authors from the UFS (eight departments and divisions in the Faculty of Natural and Agricultural Sciences) and two from SANParks in associated research collaboration with authors from 14 other institutions. 

This special issue of the Koedoe journal covered research on hydrology, flowpaths, and ground water, including the soil types and properties of different zones on the catena. As stated by Dr Janecke, there are also articles on micro-organisms, fungi, and Fusarium in the soil of the root zone of plants (rhizobiome). 

The environment is degrading fast due to human activities, and there is a dire need for research to look at the bigger picture to find solutions on how to conserve ecosystems and not only smaller parts thereof. – Dr Beanélri Janecke

The journal also comprised articles on the vegetation communities and vegetation structure in the different zones. “Research on how the vegetation recovered post-drought of 2016-2017 and on large and small mammals present on the catena and at the closest waterholes was also published. All of these topics were linked in a discussion article on the catenal ecosystem,” says Dr Janecke.

Multidisciplinary research is not conducted very often on this scale. Many researchers will rather focus on one or a few specific aspects of the ecosystem in a specialist research field. 

SANParks introduced supersite concept

Dr Janecke says scientists from SANParks initiated this supersite concept, where research can be focused on specific areas with similar geology and landscapes in the Kruger National Park to generate multidisciplinary data from separate specialist research fields. 

“Our project went one step further and combined different research fields into one project done on a supersite over the same period. This multidisciplinary project created the opportunity for specialist research fields to be published separately in one special issue, but also to combine the expertise in one project that was summarised in a discussion article.”

She believes that the environment is degrading fast due to human activities, and that there is a dire need for research to look at the bigger picture to find solutions on how to conserve ecosystems and not only smaller parts thereof. “There is a need for a more holistic approach to research, and this special issue provides a framework and basis for similar multidisciplinary studies in future,” states Dr Janecke.

This issue is currently widely marketed on all social platforms of the Koedoe journal and AOSIS Publishers, while a podcast interview is also available at:  https://soundcloud.com/aosis-za/koedoe-interview-podcast-2020 (with permission from Louw Lombaard from AOSIS).

During 2011: Prestige Scholars Programme (PSP)
2011-12-01

The University has designed the Vice-Chancellor’s Prestige Scholars Programme (PSP) to promote and support the intellectual breadth and depth required of young scholars to pose questions and generate knowledge in their disciplines and hence to occupy the vanguards of contemporary intellectual enquiry. The programme specifically targets members of the academic staff who are near completion, or have newly completed, their doctoral studies.

The goal is to select no more than 100 of the most promising young scholars and to make substantial investments in their development towards becoming full professors. A tailored, intensive programme of support is designated that combines international placement working alongside leading scholars in the discipline of the prestige scholar, with intensive mentorship and support from within the university.

Elite young scholars on the Vice-Chancellor’s Prestige Scholars Programme generated R1,2 million in National Research Foundation Thuthuka and Blue Skies funding in 2011 alone. Dr Katinka de Wet in the Department of Sociology was awarded Blue Skies funding for her work on the Hybrid Identity of the HIV/Aids patient. Thuthuka Grant holders Drs Cilliers van den Berg, Olihile Sebolai, Dirk Opperman and Diaan van der Westhuizen work in the fields of German and Afrikaans trauma literature, microbiology, structural and evolutionary biology, and architecture, respectively. This broad disciplinary range typifies the depth and extraordinary range of scholarship present among junior academics at the UFS.

Dr Liza Coetsee, a Y2-rated physicist, is the first of the Vice-Chancellor’s elite cohort of Prestige Scholars to submit for National Research Foundation rating. Dr Coetsee works on the latest of the Nanotechnology Surface Science systems housed in our Department of Physics. As Prestige Scholar, Dr Coetsee conducts research on phosphor solar cells. Her aim is to establish a new Phosphor Solar Cell field at the University of the Free State with Proff. Hendrik Swart and Koos Terblans. As a member of the Prestige Scholar Programme, Dr Coetsee will work in collaboration both with colleagues from the Nelson Mandela Metropolitan University and Prof. Eray Aydil from the University of Minnesota and Editor-in-Chief of the Journal of Vacuum Science & Technology.

Dr Olihile Sebolai is one of the 2 Vice-Chancellor’s elite Prestige Scholars and a microbiologist. In 2011, Dr Sebolai was awarded a Thuthuka Grant for his research on the yeast pathogen Cryptococcus neoformans, the cause of life-threatening Aids-defining illnesses such as meningitis. Dr Sebolai considers how cryptococcal lipids mediate infectious processes leading to illness. An understanding of these cellular processes will offer hope for future drug development to combat the scourge of cryptococcal meningitis, annually causing the death of over half a million people in Sub-Saharan Africa. Dr Sebolai is also interested in mapping the prevalence and distribution pattern of cryptococcal meningitis in the Free State. This, in turn, will assist health authorities to manage current infections and plan appropriately for potential outbreaks. The Prestige Scholars Programme, with the assistance of the National Research Foundation, will afford Dr Sebolai the opportunity to pursue his research in laboratories in the United States and India in 2012 and 2013.

Dr Louis Holtzhausen, member of the Vice-Chancellor’s Prestige Scholars Programme, has been named by the South African Sports Confederation and Olympic Committee (SASCOC) as team doctor for Team South Africa during the All Africa Games, the largest sports event in Africa. National teams from African countries participated in 23 sports events. As an esteemed South African academic in sports medicine Dr Holtzhausens’ participation was an extension of the work already being done under his supervision at the UFS’s Sports Performance Unit. Many of the athletes who prepared at the Unit were also part of the team. Elite athletes’ illness and injury profiles are one of Dr Holtzhausens’ research focus areas. The exposure to this group in competition was of great value in the identification and development of research niche areas.

Dr Lizette Erasmus, scientific chemist and one of the Vice-Chancellor’s Prestige Scholars, has just returned from a three-month-long research visit to Prof. Hans Niemantsverdriet at the Technical University of Eindhoven in The Netherlands and the University of California, Davis. Dr Erasmus specialises in heterogeneous catalysis. Her visit to Prof. Niemantsverdriet, one of the global experts in the field of surface science, served to round of existing research. In California, Dr Erasmus visited her mentor, Prof. Bruce C. Gates, as part of the objectives of the Rector’s programme for the internationalisation of young researchers. Prof. Gates, an expert in catalysis, could contribute to Dr Erasmus’ research on the characterisation of heterogeneous catalysis and catalytic reactions. In exchange, her expertise in organometallic synthesis added value to Prof. Gates’ existing research. Their continued collaboration gave availed them of the opportunity for interdisciplinary interaction between engineering (Prof. Gates’ speciality) and chemistry, and promises to contribute to increased collaboration between the two universities in future.
