A unique global study has found that wealthier neighbourhoods in cities have more biodiversity in comparison to poorer ones – a pattern that scientists have called the ‘luxury effect’. However, this study found that this effect is far greater in the more arid regions of the world. Associate Professor Arjun Amar, from the Department of Biological Sciences, is co-author of the paper published this week in the international journal Global Ecology & Biogeography.
On 30 July 2020, the National Science and Technology Forum (NSTF) will host its 22nd annual awards event in partnership with South32. This year, six researchers from the University of Cape Town (UCT) are among the finalists. Emeritus Professor William Bond, from the Department of Biological Sciences is one of them.
The vast array of species that inhabit the oceans has already proven to be an important source of innovative resources, including enzymes for COVID-19 testing and a protein valuable in the fight against the Middle East Respiratory Syndrome. As World Oceans Day approaches on 8 June, Professor Rachel Wynberg, a member of the High Level Panel for a Sustainable Ocean Economy, explains how we can better protect and share the benefits from this biodiversity to ensure it continues to be a resource for future generations.
Microfibres are fine strands of thread used to make clothing, carpeting and household items like mops. They are found in the air we breathe, the water we drink, and throughout the world’s oceans. Natural, rather than synthetic, microfibres, though, make up the majority of those found in the ocean’s surface waters – despite the fact that currently two-thirds of all human-produced fibres are synthetic. Over the course of two years and five expeditions, University of Cape Town’s (UCT) Professor Peter Ryan and his team gathered 916 seawater samples from oceans around the world.
Ice shelves, massive floating bodies of ice, are well-known for their buffering effect on land-based ice sheets as they slow their flow towards the sea. This buffering effect plays an important role in moderating global sea level rise.
When Dr Colleen O’Ryan, from the Department of Molecular & Cell Biology at UCT, embarked on an ambitious project to research the genes associated with autism spectrum disorder (ASD) in a cohort of South African children, she hardly expected the study to lead her right back to the University of Cape Town’s (UCT) Chemical Pathology laboratory where her academic career started thirty years ago.
The Bearded Vulture is one of the most threatened vultures in Southern Africa, with only around 100 breeding pairs left in the wild. In the past, the species was once far more widespread, occurring in both the Eastern and Western Cape, all the way down to Cape Town. However, the species range is now restricted to the Maloti-Drakensberg Mountains of Lesotho and South Africa. The new study, led by scientists at the University of Cape Town and published in the journal Ostrich explores where best to establish this new population
Recent discoveries by scientists at the University of Cape Town (UCT) and Iziko Museums of South Africa show how a wolf-sized otter (Sivaonyx hendeyi) and leopard-sized wolverine (Plesiogulo aff. monspesulanus) lived along South Africa’s West Coast 5 million years ago.
Here’s a different reason for tobacco to be in the news. Cape Bio Pharms, a biotech company with its origins in the Biopharming Research Unit (BRU) at the University of Cape Town (UCT), has joined the global effort to create a fast and affordable antibody test for COVID-19, using a relative of the tobacco plant.
Every year, the World Economic Forum (WEF) selects an elite group of researchers under the age of 40 to participate in their Young Scientists programme. This year, the University of Cape Town (UCT) is represented by two brilliant women scientists. Dr Sarah Fawcett, from the Department of Oceanography is one of them...
A team of international researchers has assessed the population history of prehistoric humans that lived in the region around Lake Baikal, Russia, and found the deepest connection to date between the peoples of Siberia and the Americas. The research – which combines the fields of human population genetics, the study of ancient pathogen’s genomes and isotope analysis – also demonstrates human mobility, and hence connectivity, across Eurasia during the Early Bronze Age (around 3000 to 2100 BC). Dr Petrus Le Roux, a chief research officer in the Department of Geological Sciences at the University of Cape Town (UCT), who is a co-author on the paper.
Scientists have discovered a bed of rhodoliths – free-living, coral-like structures that offer food, shelter and nursery space for marine animals – in the newly proclaimed Amathole Offshore Marine Protected Area off South Africa’s east coast. This underwater environment is the first of its kind found in South Africa’s ocean.
