The contents of a special issue of Quaternary International (QI), consisting of 13 articles and contributions by 45 authors (25 from abroad), was recently presented to Dr James Simpson Brink. The papers represent the broad range of topics covered by Dr Brink’s research interests.  

The special issue of QI was initiated to coincide with James Simpson Brink’s 60th birthday after he recently celebrated 35 years of ground-breaking research at the National Museum of Bloemfontein.

Dr Brink is affiliated to the Centre for Environmental Management at the University of the Free State (UFS).

Prof Louis Scott, researcher in the Department of Plant Sciences at the UFS, was the executive guest editor, and was part of a team of three guest editors (Dr Liora Horwitz from the Hebrew University in Jerusalem, and Dr Daryl Codron from the National Museum in Bloemfontein) who worked on this special issue of the journal, QI. 

In honour of a friend and colleague
“Dr Brink made contributions to osteology, Quaternary palaeontology, and archaeozoology, by investigating the environments and mechanisms that drove the evolution of mammal communities of southern Africa,” said the guest editors. 

“By studying the morphology of the endemic black wildebeest he demonstrated how the species evolved in the central interior of South Africa. He pioneered descriptions and dating of faunal assemblages that make up the so-called ‘Cornelian’ and ‘Florisian’ Land Mammal Ages. In this way he reconstructed the long history of environments in which Stone Age occupants survived in the region. The work included the age determination of the cranium with facial bones of an individual who lived at Floribad around 250 000 years ago.

Work enabled more important studies
“Dr Brink contributed more than purely academic insights in that he built and curated the modern mammal and fossil faunal collections of the Florisbad Quaternary Research Station. These collections made it possible for researchers, who came from all over the world, to visit the Free State and focus on spatial and temporal palaeoenvironmental trends. Apart from contributing to the functional diversity of mammalian species, this enabled the investigation of morphological and behavioural variations across populations and communities,” said the editors.

The topics of the papers in this special issue of QI are interdisciplinary and include different methods in archaeology, vertebrate palaeontology and past (or palaeo-) environmental reconstruction. The ages dealt with range from the relatively recent Iron Age to the Oldowan period, which is over a million years old.

According to Prof Scott, with a degree of overlap in the interdisciplinary fields studied, the papers can be arranged into 1) taphonomy and archaeozoology, relating to the processes resulting in the formation and preservation of fossil material in archaeological sites, 2) Stone Age archaeology, dealing with artefacts, stratigraphy and palaeoanthropology, and 3) palaeoecology, that includes palaeontology, isotope studies and palaeoenvironmental reconstructions.

The journal, published by Elsevier, will be distributed worldwide.

A great honour was bestowed on a researcher at the University of the Free State (UFS) when he was invited to the preview of the documentary film, Last of the Longnecks. Dr Francois Deacon, lecturer and researcher in the Department of Animal, Wildlife and Grassland Sciences at the UFS, who also has a role in the film, attended the preview at the Carnegie Institution for Science’s Smithsonian National Museum in Washington DC, in the US, in March this year. The preview formed part of the DC Environmental Film Festival.

The Environmental Film Festival in the US capital is the world’s leading showcase of films with an environmental theme and which aims to improve the public’s understanding of the environment through the power of film. During the festival, the largest such festival in the US, more than 150 films were shown to an audience of 30 000 plus. 

Dr Deacon was invited by the producer of Last of the Longnecks to be part of a panel handling a question-and-answer-session about the film directly after the show. He described it as the greatest moment of his life. 

Role in the film Last of the Longnecks

“My role in the film was as the researcher studying giraffes in their natural habitat in order to understand them better, so that we may better protect them, and be able to provide better education on the problem in Africa,” says Dr Deacon. 

“Together with Prof Nico Smit, also from the UFS Department of Animal, Wildlife and Grassland Sciences, Hennie Butler from the Department of Zoology, and Martin Haupt from Africa Wildlife Tracking, we were the first researchers in the world to equip giraffes with GPS collars and to conduct research on this initiative,” he says. This ground-breaking research has attracted international media attention to Dr Deacon and Prof Smit. 

“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.

“It allows us to track animals day and night, while we monitor their movements remotely from a computer over a period of a few years. These systems make the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time possible. We can even communicate with the animals, calling up their positions or changing the tracking schedules,” says Dr Deacon.

The collars, which have been designed to follow giraffes, enable researchers to obtain and apply highly accurate data in order to conduct research. Data can be analysed to determine territory, distribution or habitat preference for any particular species.

Over a period of three years (2014-2016), the Last of the Longnecks team from Iniosante LLC captured on film how Dr Deacon and his team used the GPS collars in Africa to collect data and conduct research on the animals.

“With our research, which aims to understand why giraffes are becoming extinct in Africa, we are looking at the animal in its habitat but not only the animal on its own. If the habitat of these animals is lost, they will be lost as well. Therefore, our focus is on conservation and better understanding the habitat. The giraffe is only a tool to better understand the habitat problem,” says Dr Deacon. 

Since the beginning of his research Dr Deacon and his team have had six new collar designs, with animals in four different reserves being equipped with the collars. The collars use the best technology available in the world and make it possible to determine how giraffes communicate over long distances, and how their sleep patterns function. Physiological and biological focus is placed on the giraffe’s stress levels, natural hormone cycles, and milk quality in cows.

Experience at the film festival

“Absolutely amazing. Totally beyond our frame of reference as South Africans.” This is how Dr Deacon describes his experience of the three days in Washington DC during the film festival.

“It was an absolute honour to be part of the global preview of the film and to be able to work with Ashley Davison, the director of the film, and his team. I am just a rural farm boy who dreams big, and now this dream is known worldwide!” he says. 

The film, which will be launched in April, will be screened in South Africa on the National Geographic channel in May 2017. Meanwhile, the film will also be shown at eight other film festivals in the US. 

Work will start on a follow-up documentary in October and Dr Deacon is excited about the prospect. A mobile X-ray machine will be available from October. Internal sonars could also be performed on each of the animals. Researchers from around the world will form part of the team which will be led and co-ordinated by Dr Deacon and his co-workers at the UFS.
