Un bec à bec noué (Rhyticeros cassidix) vole après avoir quitté un sommet d'arbre dans une zone de forêt tropicale près du mont Tangkoko et Duasudara (Dua Saudara) à Bitung, Sulawesi du Nord, en Indonésie. Si vous voulez participer à la réduction des impacts du changement climatique, ne tuez pas les animaux sauvages à gros corps qui mangent des fruits et dispersent de grosses graines, disent les scientifiques. Un nouvel article de la Wildlife conservation Society (WCS), publié pour la première fois sur PLOS Biology, a révélé que la chasse excessive de ces espèces rend les forêts moins capables de stocker ou de séquestrer le carbone. les grands frugivores tels que les primates, les cornes, et d'autres sont...

A knobbed hornbill (Rhyticeros cassidix) flies after leaving a tree-top in a rainforest area near Mount Tangkoko and Duasudara (Dua Saudara) in Bitung, North Sulawesi, Indonesia. If you want to participate in reducing climate change impacts, do not kill large-bodied wildlife that eat fruit and disperse large seeds, scientists say. A new paper by the Wildlife Conservation Society (WCS), which is first published on PLOS Biology, revealed that overhunting of these species makes forests less able to store or sequester carbon._Large frugivores such as primates, hornbills, and others are fruit eaters that disperse large seeds from tree species with high carbon stock capacity, according to the scientists. In other words, losing these species will change the composition of forests: wind-dispersed or small-seeded tree species with lower wood density, and therefore lower amounts of carbon, become more prevalent._"Many tropical forests have been described as 'empty' owing to loss of animals, often as a result of unsustainable subsistence or market hunting. Such hunting is known to have detrimental effects on target species, broader biodiversity, and the livelihoods and well-being of local communities. Less appreciated is the adverse impact of defaunation on the capacity of tropical forests to sequester and store carbon, which has implications for climate change, " said the lead author, Dr. Elizabeth Bennett, as quoted by ScienceDaily._High-integrity tropical forests are estimated to remove and store around 3.6 billion tons of CO2 per year (net) from the atmosphere, according to the report.
