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).

Twee broers lewer intreerede
2004-06-10

‘n Unieke geleentheid sal homself môre, 9 Junie 2004, voordoen wanneer twee broers - proff Francois en Janse Tolmie - tydens dieselfde geleentheid hul intreeredes aan die Universiteit van die Vrystaat (UV) sal lewer.

Prof Francois Tolmie is verbonde aan die UV se Departement Nuwe Testament en die onderwerp van sy lesing is Die impak van die metodologie op die verstaan van die Nuwe Testament. Prof Janse Tolmie, sy jonger broer, is verbonde aan die UV se Departement Rekenaarwetenskap en Informatika en die onderwerp van sy lesing is Die rol van inligtingstegnologie in kennisbestuur.

Hoewel die studievelde vér verwyderd staan, klop die twee broers se missies wat betref die terugploeg van die verworwe vakkennis ten bate van die gemeenskap. Prof Francois Tolmie is nóú betrokke by dowes en Prof Janse Tolmie tap weer kunsmatige intelligensie ten bate van die mediese wetenskap en geestesgesondheid.

Prof Francois Tolmie verwerf die grade BA, BA Honneurs (Grieks), MA (Grieks), B Th en M Th almal cum laude aan die UV. In 1992 verwerf hy 'n D Th (Nuwe Testament) en in 2004 'n Ph D (Grieks) aan dieselfde universiteit. Na sy militêre diens as kapelaan in Walvisbaai aanvaar hy 'n beroep na die NG-gemeente Walvisbaai. Hy begin sy akademiese loopbaan op 1 April 1990 as senior lektor in die Departement Nuwe Testament en word in 1999 tot medeprofessor en in 2003 tot professor bevorder.

Sy navorsingspesialiteit is die Johannesevangelie en die Brief aan die Galasiërs. Hy is tesourier van die Nuwe Testamentiese Werksgemeenskap van Suid-Afrika, lid van die Society of Biblical Literature en die Studiorum Novi Testamenti Societas, redakteur van Acta Theologica en assistent-redakteur van Neotestamentica. Hy het reeds 34 artikels in geakkrediteerde tydskrifte gepubliseer, asook drie populêr-wetenskaplike boeke en talle bydraes in populêr-wetenskaplike boeke. Hy het twee akademiese boeke in die buiteland gepubliseer - onderskeidelik in Nederland en in die VSA. Later vanjaar verskyn 'n derde akademiese boek in Duitsland. Hy is ook een van die vertalers van die Afrikaanse Bybel vir Dowes.

Prof Janse Tolmie verwerf die grade B Sc, B Sc (Hons) en M Sc (Cum Laude) in Rekenaarwetenskap aan die UV.

Hy is vanaf 1989 betrokke by die UV en was ook ’n dosent aan die Militêre Akademie in Saldanhabaai in 1990/91 en het klas gegee by DePaul Universiteit in Chicago in 2002.

In 1992 is hy vir ses maande gesekondeer na ’n patologiese firma, Van Drimmelen en Vennote, in Johannesburg vir die ontwikkeling van kennisgebaseerde sagteware. Met hierdie projek word hy een van slegs ’n handjievol navorsers in die wêreld wat daarin kon slaag om ’n mediese kundigheidstelsel te ontwikkel wat werklik gebruik word.

Hy verwerf sy Ph D in 1994 en in 1994/95 doen hy navorsing aan die Besigheidskool van Carleton Universiteit in Ottawa, Kanada. Hy word in 1997 bevorder tot mede-professor en in 2003 tot volprofessor. Vanaf 2003 tree hy op as departementele voorsitter van die UV se Departement Rekenaarwetenskap en Informatika.

Hy het meer as 30 publikasies al die lig laat sien, insluitend verskeie internasionale kongresbydraes en artikels in geakkrediteerde joernale. Hy was ook vir 2 siklusse geëvalueer by die NRF. Sy portfolio sluit in die ontwikkeling van sagteware of prototipes vir groot maatskappye soos Van Drimmelen en Vennote en Bayer Diagnostics (VSA). Sy privaatbesigheid fokus op die ontwikkeling van nismarksagteware vir tersiêre instellings. Die sagteware word tans gebruik deur afdelings aan verskeie universiteite in Suid-Afrika.

Die geleentheid vind om 19:00 in die CR Swart-ouditorium op die kampus plaas.
