The acclaimed scientific journal, Nature, recently published an article about a trace fossil in approximately 543-million-year-old rocks, which elucidates the evolution of the first animals that appeared on Earth and lived in the sea.  

Affiliated Professor in the Department of Geology at the University of the Free State (UFS) Prof Gerard Germs formed part of a team that conducted research with the aim of understanding how the evolution of the first multicellular animals came about and how the Cambrian explosion took place. Prof Germs is of great value to the team for his extended field geological knowledge.

An article which he co-authored was published in the Nature Scientific Reports. The title of the article is: “Sediment disturbance by Ediacaran bulldozers and the roots of the Cambrian explosion”. The international group of writers included authors from Canada, Spain and South Africa. 

Occurrence of the Cambrian explosion
Prof Germs explains the Cambrian explosion: “During the long (4.5-billion-year) history of the Earth, the first life originated and subsequently evolution of plants and animals took place from one-cellular organisms to multicellular vertebrate animals and seed plants. Approximately 573 million years ago the first multicellular animals appeared on the scene. Sometime afterwards, approximately 540 million years ago, a kind of explosion in the origin of many new animal species occurred. This explosion is known as the Cambrian explosion.”

The team studied Earth sediments which are somewhat older than the Cambrian explosion. Such sediments are approximately 573 to 541 million years old and form part of the Ediacaran (late Neoproterozoic) period.

“My discoveries of the past, of among others, the oldest animal with a carbonate skeleton (Cloudina) and of complex horizontal Cambrian-type “worm” tracks (treptichnids) in Ediacaran sediments of Namibia have demonstrated that the Cambrian explosion occurred more gradually than previously thought. This has recently been confirmed in the article that was published in the Nature Scientific Reports.”

Pretzeliformis bulldoze to search for food
According to the article there is evidence that   during the Ediacaran period   worm-like animals such as the Parasammichnites pretzeliformis were already so far developed that they, due to coelom development and size increase, for the first time in the history of the Earth, were able to disturb and bulldoze sediments.  In this way they were able to find a new food source in sea sediments. Bulldozing animals were previously thought to have originated only during and after the Cambrian explosion and not during the older Ediacaran.

“Another major aim of my cooperative research is to improve our knowledge of the geology of the Ediacaran to early Cambrian of South Africa and Namibia. We also intend to establish how the assembly of the supercontinent Gondwana took place. This improved knowledge can be of great future economic interest since large oil, gas and limestone sources occur in Ediacaran-age sediments outside South Africa”.

UFS Communication and Brand Management receives two prestigious international awards
2015-07-07

The Department of Communication and Brand Management at the University of the Free State (UFS) received two of the six Gold Quill Awards – that were awarded to South African companies and institutions - at the International Association of Business Communicator’s (IABC) Excellence Gala ceremony in San Francisco, US on 15 June 2015.

The awards ceremony formed part of the 2015 IABC World Conference, which took place from 14-17 June 2015. The department received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook and a Gold Quill Merit Award for the B Safe Take Action campaign.

From the 15 countries that entered, a total of 120 Gold Quill Excellence awards and 189 Gold Quill Merit awards were awarded. Other South African award winners included Barclays Africa Group Limited, Mediclinic and the Cape Peninsula University of Technology (CPUT).

This is the second year in a row that the UFS has been recognised by the IABC for its communication projects. In 2014, the department was awarded the Jake Wittmer Research Award for a Stakeholder Perception Audit conducted in February 2014. The audit was considered – by the IABC - as one of the best breakthrough strategies used by a university to measure the perceptions of its stakeholders.This made the UFS the first tertiary institution in Africa to receive the research award. The stakeholder perception audit also received an Africa Gold Quill in 2014.

"Being recognised by a global association such as the IABC for the second time, is a great honour and I am very proud of what my colleagues have achieved by entering the two campaigns. Winning the awards is a true indication of what can be done when a team of expert communicators is committed towards engaging their target audiences with campaigns that speak of quality and innovation. The fact that the UFS is one of only two tertiary education institutions in the country to receive these prestigious awards, makes it even more special," said Lacea Loader, Director: Communication and Brand Management at the UFS.

IABC World and Africa conferences 2015 

The IABC is a global membership association with a network of 12 000 members in more than 80 countries, representing many of the Global Fortune 500 companies. It serves professionals in the field of business communication, bringing together the profession’s collective disciplines.

With the theme: Changing landscape: Informing the future, the 2015 world conference was attended by over 1 200 delegates from across the world. Delegates were offered an opportunity for learning, discovering, and connecting. Loader also made a presentation entitled ‘Award-winning measurement endorses sound reputation management strategy’ at the world conference.

The department will also be receiving two Africa Gold Quill Awards from the Africa chapter of the IABC for the same campaigns on 30 July 2015 in Johannesburg.

UFS #FaceOfFacebook Campaign

The university received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook. This initiative originated in the university’s commitment to its Human Project, which sets the standard for good behaviour and care.

Lelanie de Wet, Manager: Social Media and Website Content and project leader of UFS #FaceOfFacebook, said the project was born from the need to communicate with students. Thus a virtual friend, #FaceOfFacebook, was created. “Yearly auditions are being held to choose the new face representing the UFS on Facebook. Short video clips of the #FaceOfFacebook – whether it is attending events or communicating important messages - are posted on the UFS Facebook page. The successful candidate holds the title #FaceOfFacebook for 12 months.

“When I look at a campaign such as #FaceOfFacebook, from the time it took its first tentative steps in 2013, and see how it inspired staff and students alike, my heart swells with pride. Often you can see the impact you have made only in retrospect. The ripples you send into the world will inevitably create waves,” she said.

B Safe Take Action Campaign

The B Safe Take Action campaign of the university received a Gold Quill Merit award from the IABC.

The campaign was activated in September 2013. “It targeted on- and off-campus students and staff, aiming to create social ownership of personal safety, and to raise awareness of the safety measures put in place by the university,” said Leonie Bolleurs, Manager: Internal Communication and project manager of the campaign.

The campaign looked at a number of safety aspects, focusing not only on crime but also on being safe from road accidents and stress/burnout.

It is the second time this year that the BSafe campaign has been recognised for its innovative strategy. Earlier this year it received a PRISM Award (Gold) from the Public Relations Institute of Southern Africa (PRISA). The annual PRISM Awards are about recognising and celebrating great public relations campaigns.
