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).

Researchers reach out across continents in giraffe research
2015-09-18

Dr Francois Deacon and Prof Fred Bercovitch
busy with field work.

Researcher Dr Francois Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State is conducting research with renowned wildlife scientist, Prof Fred Bercovitch, from the Center for International Collaboration and Advanced Studies in Primatology, Kyoto University Primate Research Institute in Japan.

Dr Deacon’s ground-breaking research has attracted international media attention. Together with Prof Nico Smit, he equipped giraffes with GPS collars, and conducted research based on this initiative. “Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.”

Prof Bercovitch was involved with GPS tracking from elephants to koala bears.

Some of the highlights of the joint research on giraffes by Dr Deacon and Prof Bercovitch focus on:
 
• How much time do certain giraffes spend with, and away from, one another
• How do the home ranges of herds and individual giraffe overlap
• Do genetically-related animals spend more time together than non-genetically-related animals
• How much time do the young bulls, adult bulls, and dominant bulls spend with cow herds
• Herd interactions and social behaviours of giraffe
• The role of the veld and diet on animal behaviour and distribution

 

Their research article, “Gazing at a giraffe gyroscope: Where are we going?”, which was published in the African Journal of Ecology, assesses recent research by exploring five primary questions:

- How many (sub) species of giraffe exist?
- What are the dynamics of giraffe herds?
- How do giraffe communicate?
- What is the role of sexual selection in giraffe reproduction?
- How many giraffe reside in Africa?

They conclude this article by emphasising that the most essential issue is to develop conservation management plans that will save a wonderful species from extinction, and which will also enable scientists to conduct additional research aimed at answering their five questions.

In addition, they are working together on a grand proposal to get National Geographic to cover their work.
