Rhino Conservation
Should the ban on trade in rhino horn be lifted and South Africa could generate financial incentives, a large percentage of the funds should be allocated towards the conservation of the Java, Sumatra and Indian rhino.

Water, cold, thirst, volcanoes …. and poaching, are causing the death of rhinos across the globe. 

Recently, a group of scientists and rhino activists met at the University of the Free State (UFS) to discuss the plight of rhinos in South Africa. Bringing an international perspective to the colloquium on global rhino conservation, were three delegates from Indonesia who are working with the most endangered rhinos on earth – the Javan and Sumatra rhinos. 

Dr Rudi Putra, a biologist, received a Goldman Environmental Prize in 2014 for his efforts to save the Sumatra rhinos – of which an estimated 65 individuals are left in the Gunung Leuser National Park. Muhamnad Syamsudin is responsible for a 30-person rhino protection unit, which has not lost one rhino to poaching in Ujung Kulon National Park in 19 years. The third person from the Indonesian delegation was Dr Firmanto Noviar Suwanda, a lead scientist in rhino observation data, with a 30-person rhino monitoring unit, also in Ujung Kulon National Park.

Also presenting at the colloquium, were researchers from an inter-disciplinary team at the UFS, who are working together to establish a rhino conservation model through research and teaching.

The colloquium was convened by the UFS.

Rhino revolution 

According to Dr Willem Daffue, a veterinarian from Kroonstad, the world needs a rhino revolution. “What we have been doing, is not working,” he said.

South African rhino farmers own almost half of the rhino population in the country. Dr Daffue shared facts on rhinos introduced to private captivity. “In the beginning, the animals died of thirst (the white rhino cannot lift its head to drink from a water trough), cold, and killing each other. And then poachers killed them …”

In 2009, South Africa saw an unprecedented spike in horn poaching, resulting in CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) implementing a ban on the sale of rhino horn within South Africa. The international sale of rhino horn – in an attempt to halt the unrelenting slaughter of rhinos in Africa and Asia – was already banned by CITES in 1977.

Role players agree that banning the trade in rhino horn is not the answer. The status quo is not working. 

For two weeks after the colloquium, Dr Deacon, Dr Daffue, and the Indonesians met with several role players in the rhino industry, including Dr Jana Pretorius (Rhino Pride Foundation), who established immediate, practical preventative measures to protect rhinos from poachers. Other people who were visited, were Dr Johan Marais (Saving the Survivors) who is tending injured endangered wildlife that have fallen victim to poaching, as well as Dr Danie Pienaar and Dr Markus Meyer (SANParks scientific services in the Kruger National Park’s Skukuza headquarters). They also knocked on the doors of Anton and Clive Walker (authors of Rhino Revolution) as well as Petronel Nieuwoudt (Care for Wild Rhino Sanctuary NPC), who is one of the few people worldwide who specialise in the care of orphaned rhinos.

“All role players feel that if they could sell the horns, they could easily afford to keep the animals secure.  And the horns are harvestable. We just trim them – as with sheep's wool. They grow back at up to 10 cm (4 inches) a year,” explained Dr Deacon. 

“Decision making, specifically about legalising the trade in rhino horn, needs to change. Involved parties feel that countries must decide, or more specifically, the role players in the industry – people with a responsibility towards the animals. It must not be up to CITES,” he said.

Safety for all rhinos


CITES met at the same time that the UFS team hosted the Indonesian party. “The timing of the trip was perfect, because CITES and the ban was being discussed. The status quo remains, however, as the ban on rhino-horn trade was not lifted,” said Dr Deacon.”

“It became apparent – we simply will not allow trade of South African rhino horn if we cannot secure the wellbeing and a safe haven for the Java, Sumatra, and the Indian rhino. We strongly discourage any sort of trade if one species is favoured while the others are facing a dark future,” stated Dr Deacon.

They proposed to different stakeholders that, should the ban on trade in rhino horn be lifted and South Africa could generate financial incentives, a large percentage of the funds should be allocated towards the conservation of the three Asian rhinos.

More research

At the UFS, the interdisciplinary team is continuing to work on research to breed a hardened animal through the project ‘Ecological and biological factors regulating rhino in captive environments.’ They are in the process of collecting data from 750 rhinos across South Africa. Several members of the team presented at the colloquium. 

Prof Paul Grobler from the Department of Genetics informed attendees on the role of genetics in rhino protection, focusing on touch DNA. He said it only takes seven to eight cells to amplify touch DNA that could link a perpetrator to a crime scene. With rhino poaching, touch DNA can be applied on the skin of the animal by collecting skin cells with tape lifting or swabs. 

Rolene Grobler, also from the UFS Department of Animal, Wildlife and Grassland Sciences, talked about how research on IVF, surrogacy, and cryopreservation of semen and embryos could be considered to save the rhino. 

Dr Hennie Butler from the UFS Department of Zoology and Entomology specifically focused on the behaviour of rhinos after dehorning or trimming of the horns. “Losing their horns will have an effect. Research has shown that the animals are more stressed, affecting birth rates, a change in habitat, and their social behaviour within bigger groups.” 

Also talking at the colloquium, were Dr Frans O'Neill, who focused on the cholesterol of the animals, and Dr Gary Osthoff, who looked at the milk production of the animals.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
