The ramifications of human activity on Madagascar will affect the country far longer than previously realized, scientists say. It could take millions of years for the biodiversity on the island to recover.
It could take millions of years for the biodiversity on the island to recover from extinctions spurred by human activity, according to a study published Tuesday inLowland Streaked Tenrec . A species of tenrec, a diverse and unique group of mammals found only on Madagascar.
Madagascar Sucker-footed Bat . The Madagascar Sucker-footed Bat belongs to an ancient family of bats that is found only on Madagascar.The impacts were much greater than scientists expected, Luis Valente, author and researcher at the Naturalis Biodiversity Center and the University of Groningen in the Netherlands, told ABC News.
Even bat species, which can colonize islands more easily than non-flying mammals, may need about 3 million years to recover, according to the paper. The number of Madagascar's mammal species threatened with extinction has increased dramatically in the past decade, from 56 in 2010 to 128 in 2021.

It would take 23 million years for evolution to replace Madagascar's endangered mammalsIn many ways, Madagascar is a biologist's dream, a real-life experiment in how isolation on an island can spark evolution. About 90% of the plants and animals there are found nowhere else on Earth. But these plants and animals are in major trouble, thanks to habitat loss, over-hunting, and climate change. Of the 219 known mammal species on the island, including 109 species of lemurs, more than 120 are endangered. A new study in Nature Communications examined how long it took Madagascar's unique modern mammal species to emerge and estimated how long it would take for a similarly complex set of new mammal species to evolve in their place if the endangered ones went extinct: 23 million years, far longer than scientists have found for any other island.
