Lucien De Coninck award for Sandrine Godefroid


On Sunday, 30th March, at 10:30 am, the Lucien De Coninck award will be presented for the 11th time in the Rector Vermeylen hall of the Pand. The purpose of this award, with a value of 2,000 Euro, is to honour distinguished scientific work in a spirit of liberal humanism and interdisciplinary cooperation.
Following the advice of a specialised jury, the Fund Manager, Lucien De Coninck, decided to grant the award to Dr. Sandrine Godefroid, researcher at the Vrije Universiteit Brussel. Sandrine Godefroid is a doctor of Botany and a dedicated researcher in the field of phytosociology, mainly in the Brussels Capital Region. She has a very impressive scientific CV, but also spends a lot of time in the popularisation of scientific research.

Amphibians challenge traditional plate tectonic models

One of the most important and far-ranging geological theories of all time is that of plate tectonics, the notion that many continents and islands (South America, Africa, India, Madagascar, Antarctica,…) once formed a single ‘supercontinent’ called Gondwana, and steadily moved away from each other to give rise to the modern oceans. Ever since Alfred Wegener proposed this theory in 1915, biologists have used it to explain the distribution of many plants and animals across the world.

With improving precision, geologists have shown that Gondwana’s major landmasses started separating in the Early Cretaceous period (approximately 145-100 million years ago). This information provides an estimate for the time at which plants and animal species on disconnected continents diverged from each other.

However, in a recent paper in the journal PloS One by Van Bocxlaer et al., a team of Belgian and Indian scientists led by Franky Bossuyt (Vrije Universiteit Brussel) found a different pattern.

Based on DNA sequences, they discovered that two large frog families simultaneously spread across most of Gondwana’s continents in the Late Cretaceous (100-65 million years ago), long after these landmasses started moving apart.

Because amphibians cannot survive in salty environments for a long time, it is unlikely that these frogs acquired their widespread distribution by swimming or rafting across the rapidly widening oceans between the continents. Instead, the scientists suggest that intervening, presently submerged landbridges may have connected the separating continents and allowed faunal interchange for a prolonged period. Palaeontologists had already noticed that mammalian, dinosaur, and crocodilian taxa attained widespread distributions only by the Late Cretaceous, i.e., after the geological break-up events.
The study also shows that landmasses that are now unviable for most species, such as Antarctica, must have played a central role in the Late Cretaceous range extensions of animals.

Both pictures display a treefrog from India.
The closest relatives of this family of Asian treefrogs is a group of frogs that lives in Madagascar. Both families probably diverged after the traditionally depicted geological break-up of India and Madagascar at 88 million years ago, which indicates that a terrestrial landbridge (in this case the Seychelles plateau) may have connected these landmasses for a prolonged time.
