Biological expeditions to the unexplored central highlands of Angola between 2016 and 2019 led to the discovery of a new tiny, white-thumbed bat species from Eswatini by Prof Peter John Taylor from the UFS Department of Zoology and Entomology and the Afromontane Research Unit (ARU), together with colleagues from the University of Eswatini (UNESWA) and other collaborators.

The bat species, named Neoromicia hlandzeni or the Lowveld serotine bat – after the Lowveld of Eswatini (eHlandzeni) – is the first new animal species to be discovered in Eswatini and given a siSwati name. The Lowveld serotine bat is tiny at four grams, has a distinctive white thumb pad, and occurs in Eswatini, South Africa, Zimbabwe, and Mozambique.

Bats make up a quarter of all mammalian biodiversity. With modern technology and the exploration of previously inaccessible regions of Africa, the rate of discovery of both animal and plant species is accelerating.

According to Prof Taylor, the Lowveld serotine bat is a new species to science. The specimen from which the species was named was collected in the lowlands of Eswatini in 2005. “Later collections of bats from the highlands of Angola, undertaken by myself and students, revealed the fact that the highland and lowland forms were actually different species. Since there was already a name for the highland bat, we needed to find a new name for the lowland bat from Eswatini and South Africa, hence it is called the Lowveld serotine bat,” he said.

The importance of integrative taxonomy, local collaboration, and biodiversity surveys

Prof Taylor is a research fellow of the National Geographic Okavango Wilderness Project, and the bat discovery took place during expeditions under the patronage of the Angolan government, the Wild Bird Trust, and the National Geographic Okavango Wilderness Project. He said the aim of the expedition was to explore the plants and animals of a wilderness area (the source of the Okavango) that had not been explored before.

The discovery also led to their paper being published in the scientific journal, the Zoological Journal of the Linnean Society, this month.

The publication, titled Integrative taxonomic analysis of new collections from the central Angolan highlands resolves the taxonomy of African pipistrelloid bats on a continental scale, showcases the importance of integrative taxonomy, local collaboration, and biodiversity surveys, as the description of this exciting new species would not have been possible without comparative genetic and morphological material from new collections in the poorly sampled central highlands of Angola.

Afromontane regions as hotspots of bat speciation, diversity, and micro-endemism

Although Prof Taylor is the first author to describe this new species, the work was done with a multidisciplinary team of colleagues, students, and collaborators from the UFS, UNESWA, the University of Pretoria, the University of Venda, and Stellenbosch University, as well as the Durban Natural Science Museum and the Ditsong National Museum of Natural History, with support from the Angolan government, the Wild Bird Trust, and the National Geographic Okavango Wilderness Project.

“Describing a new species is an arduous task that can take years from discovery to publication. All the enormous collective efforts have shown the importance of collaborative biodiversity exploration using old and modern technologies, as well as the African ownership of this discovery,” Prof Taylor said.

Three of Prof Taylor's previous and current PhD students – all of them South African women – were part of this discovery process and are co-authors of the paper. All 14 co-authors in the team are African. Prof Taylor said the discovery adds a new species to the total bat list of 125 species for Southern Africa – at number 126.

UFS involved in project to light up the townships

2006-06-06

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
