Inaugural lecture focuses on aspects of soil classification
Prof Cornie Van Huyssteen delivered his inaugural lecture on the topic: ‘The world in a grain of sand’, at the ninth inaugural lecture at the UFS this year.
Humans classify their environment to create order, make it more understandable, aid recollection and to communicate. As important it is for humans to classify their environments, so it is to classify soil, said Prof Cornie van Huyssteen.

Prof Van Huyssteen has studied and recorded data on soil worldwide to find the most appropriate use of land, in among others, the agriculture and mining sector and for urban development. 

It is all about soil

He was vice-chair of the International Union of Soil Sciences working group for the World Reference Base, and president of the Soil Science Society of South Africa. From 1991 to 1999 he worked at the Institute for Soil, Climate and Water of the Agricultural Research Council, where he aided in the land type survey and spatial analysis of soil data.

At his recent inauguration to full professor Prof Van Huyssteen delivered the ninth inaugural lecture at the University of the Free State’s Bloemfontein Campus for 2018, talking about a matter close to his heart, soil. He titled the lecture: ‘The world in a grain of sand’. 

Relevant to irrigation scheduling

A professor in the UFS Department of Soil, Crop and Climate Sciences, Prof Van Huyssteen’s research focuses on the relationship between soil morphology and soil hydrology. It can mostly be applied to hydropedology, wetland delineation, urban development, mining EIAs, irrigation scheduling and soil classification.

Prof Van Huyssteen joined the UFS in 2000, and in 2004, he completed his PhD in Soil Science. He is also author or co-author of 25 reviewed papers.

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.
