A group of three students from the University of the Free State – Shaun Redgard (Department of Chemistry, Edward Lee (Department of Physics), and Chantelle Booysen (the Human Molecular Biology Unit, Department of Haematology and Cell Biology) – emerged as winners ofthe 2019 International Natural Sciences Tournament (INST).

– emerged as winners of the 2019 International Natural Sciences Tournament (INST).

The final stage was held at the Tallinn University of Technology (TalTech) in Tallinn, Estonia, from 1 to 5 February 2019.This was the 9th annual presentation of the tournament that was originally launched in Russia.

According to the organisers, the principal goal of the tournament is to teach young engineers and scientists to use their knowledge to solve real-world problems.

There were six participating teams in the final part of the tournament. Participants from South Africa and Russia had to solve a dozen difficult problems in the spheres of medicine, biology, physics, and chemistry.

This year, the organisers decided to add some tasks with a straightforward connection to daily human life.

Redgard, who was the captain of the team, along with Lee, Booysen, and their coach, Dr Hendrik van Heerden (from the UFS Department of Physics), attended the tournament for the very first time, but they showed a high-level game.  

The final debate was held between the students from South Africa and Russia. The team from South Africa was persistent, confident, and structured. According to the judges, the finalists solved all the problems in accordance with the tournament rules. “The students were creative and original in solving all of the tasks, and this led them to victory,” they said.

The panel of judges was composed of a mix of bright specialists from universities as well as industrial and consulting companies operating in Estonia, the United States, the Netherlands, Portugal, Latvia, and Russia.

The founder of the tournament, Dr Sergey Safonov from Russia, says about the competition: “Our mission is to bring real-world problem-solving skills to bright scientists around the globe. We believe that science is not just an interesting subject of study, but a real instrument of changing the surrounding world, creating new products, and solving environmental problems. We believe that there are a lot of talented students around the world who seek to find their place in science and industry”.

Breeding of unique game requires a balance between conservation and sustainable use
2014-05-20

 

Game bred for qualities such as unconventional hair colour or horn quality, may on the long term have unexpected consequences for biodiversity and game farming.

This is according to the inaugural lecture of Prof Paul Grobler from the Department of Genetics at the University of the Free State (UFS).

Prof Grobler feels that the consequences of selective breeding should be examined carefully, as there is currently much speculation on the subject without sound scientific information to back it.

“At the moment, colour variation invokes much interest among game farmers and breeders. Unusual colour variants are already available in different game species. These unusual animals usually fetch much higher prices at auctions compared to prices for the ‘normal’ individuals of the species.”

Examples of these unusual variants are springbuck being bred in white, black or copper colours, the black-backed or ‘saddleback’ impala, and the gold-coloured and royal wildebeest.

A black-backed impala was recently sold for R5,7 million.

“Based on genetic theory, good reason exists why these practices need to be monitored, but one should also take care not to make the assumption that selective breeding will inevitably lead to problems,” warns Prof Grobler.

Grobler says that negative characteristics in a species can sometimes unwittingly be expressed during the selection process for a unique colour. “It is seen, for example, in purebred dogs where the breeding of a new race sometimes brings underlying genetic deviations in the species to the front.” He also believes that some of these animals may not be able to adapt to changing environmental conditions.

“However, one should also look at the positive side: because of the good demand for game, including unusual variants, there is much more game in South Africa today than in many decades. Balance should be found between the aims of conservation and the sustainable utilisation of game.”

Research at the UFS’s Department of Genetics is now trying to establish the genetic effects of intensive game breeding and predict the impact on biodiversity.
