Insects are the best example of biodiversity.
They represent the third of the living species and scientists discover new specie every day.
One group in particular has survived through many geological events : the insects.
While climate was changing regularly, they were able to adjust and develop.
Today, it is the human’s impact that is presenting a threat to insects.
With Philippe Le Gall, entomologist from IRD, we try to understand how, in this area of Cameroun mountains, the living is always in motion...
The coleoptera group accounts for about 350,000 species which is about a fourth of the total known species of one million.
Using the insects and their major biodiversity, availability and size, scientists have now a fundamental model that they can use for their research.
Visiting this exhibition, you can venture deep into the heart of the tropical rainforests -of Latin America, Africa or Asia- and discover how far they are essential for the future of our Earth!
Cereals are one of the main staples of humans in sub-Saharan Africa. This is particularly true in Kenya where maize occupies the first place.
It is consumed in different ways : grilled, boiled as porridge, and ugali, which is favored national dish.
In Kenya, maize is mainly grown by small-scale peasant farmers.
Unfortunately, like other cultivated crops, maize is attacked by a plethora of diseases and insect pests, among the cereal stemborers.
The Saharan cousin of Mediterranean olive trees remains largely unknown. However, this subspecies (called the Laperinne's olive tree) is of great interest for several reasons. IRD researchers and their partners showed that its longevity is ensured by its original vegetative reproduction. Extremely drought-resistant, this "relict" tree could act as a genetic resource to improve its domestic counterparts, provided conservation actions are implemented to prevent its disappearance.
