Islands and island environments faced with global changes

Openness to the outside world, incorporation within the global economy but also the growth in natural risks and rising sea levels.... With their unique characteristics, often under threat, island environments and communities are today faced with unprecedented destabilising factors.
In the ocean, near a sandy bottom, a good-sized coelacanth faces a diver.

The new coelacanth has arrived?

Indonesian and French scientists have identified what they believe to be a new species of coelacanth, shedding light on the biogeographical mechanisms at the origin of the divergence between the populations known to date. The history of the evolution of this group of fish, little changed in...

Mercury levels in tuna: Verifying the size, species, and origin!

Tuna is a widely-loved food around the world, but it can harbour a toxin: methylmercury. According to a recent study, the levels of this toxin in Central and Southwest Pacific tuna depends not only on the size and species of the fish, but also their geographic origin. These results are crucial for...

Genetic diversity in millet: a past and future adaptive advantage

Having sequenced the millet genome, an international consortium involving French researchers from IRD, Indian, Chinese researchers and numerous laboratories from the North and South, studied different wild and cultivated varieties. This allowed them to trace the history of cultivated millet and...

New hydroclimatic conditions in the Sahel

The latest figures on soil and climate help explain the enigmatic ups and downs observed in Sahelian hydrology for decades. Knowledge of the mechanisms involved paves the way for practical solutions to adapt agriculture to new environmental conditions.

El Niño and weather hazards

The El Niño events of 2015 and 2016, heralded by similar early signs, had very divergent amplitudes. Their modelling highlights the importance of unpredictable high-frequency winds. The ability to predict the phenomenon is therefore severely limited.
