Biodiversité

Des protocoles de suivi scientifique simples et ludiques permettent aux participants de découvrir la faune visible de leur sol : fourmis, cloportes, mille-pattes ou encore araignées. Les objectifs du programme sont à la fois de renseigner une base de données de suivi de la qualité biologique de ces sols à l’échelle nationale et de permettre aux citoyennes et citoyens d’en apprendre davantage sur les enjeux liés à la préservation de ce compartiment de la biodiversité dont les rôles sont trop souvent insoupçonnés.

Maps of the human footprint allow ecologists to identify the wildest lands on the planet, track their decline, and prioritize wildland conservation efforts. Other research efforts have mapped biological intactness and identified conservation priorities to protect biodiversity. However, little research has involved the use of historical references to evaluate intactness of species composition globally. We used a dataset estimating historical and current distributions of mammals to address whether the wildest places on Earth support the most intact mammal communities. Contrary to our expectations, we found that the global human footprint was not strongly correlated with mammal community intactness and uncovered surprising situations where both the human footprint and mammal species intactness were high, and other examples where both were low.

In the French West Indies, more than 20 species of cetaceans have been observed over the last decades. The recognition of this hot spot of biodiversity of marine mammals observed in the French Exclusive Economic Zone of the West Indies motivated the French government to create in 2010 a marine protected area (MPA) dedicated to the conservation of marine mammals: the Agoa sanctuary. Threats that cetacean populations face are multiple but well-documented. Cetacean conservation can only be achieved if relevant and reliable data are available, starting by occurrence data.
