Researchers have documented the longest-known terrestrial migration of wildlife in Africa – up to several thousand zebra covering a distance of 500km (more than 300 miles) – according to World Wildlife Fund (WWF).
Using GPS collars on eight adult Plains zebra (Equus quagga), WWF and Namibia’s Ministry of Environment and Tourism (MET), in collaboration with Elephants Without Borders (EWB) and Botswana’s Department of Wildlife and National Parks, tracked two consecutive years of movement back and forth between the Chobe River in Namibia and Botswana’s Nxai Pan National Park, a straight-line distance of 250km (500km round-trip). The findings are detailed in the study, A newly discovered wildlife migration in Namibia and Botswana is the longest in Africa, published today in the journal, Oryx.
The discovery comes at a time when migrations of a diverse range of species around the world are increasingly imperiled, and zebra migrations in other parts of Africa have been disrupted by physical barriers such as fences.
“This unexpected discovery of endurance in an age dominated by humans, where we think we know most everything about the natural world, underscores the importance of continued science and research for conservation” said Dr. Robin Naidoo, senior conservation scientist at WWF.
The potential conservation implications of the study are considerable. The observed migration takes place entirely within the Kavango Zambezi Transfrontier Conservation Area (KAZA) – the world’s largest multi-country conservation area. Spanning 109 million acres across Namibia, Botswana, Zimbabwe, Zambia and Angola, KAZA exemplifies the kind of large landscape conservation approach that will be necessary to preserve the world’s remaining great terrestrial migrations.
“The findings of this study emphasize the importance of trans-frontier conservation areas in conservation of the greater landscape” said Pierre Du Preez, Chief Conservation Scientist at MET in Namibia. “This study has played a crucial role in helping determine a key wildlife corridor in KAZA.”
“At a time when conservation news is inherently rather negative, the discovery of this unknown natural phenomenon should resonate with people around the world. The government’s commitment to secure key migratory corridors serves to underpin the growing wildlife tourism industry. We plan to continue monitoring the migration to try and conserve such increasingly rare natural events” said Dr. Mike Chase, EWB’s founder.
Continued long-term research will be needed to confirm that this is an annual and fixed migration, and whether this is genetically coded or passed behaviorally from mothers to offspring.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
