Habitat fragmentation increases genetic distance between fruit bat subpopulations

“…Unlike Mohéli's forests, which have a lower rate of disturbance (the island benefits from conservation measures in place since the creation of a protected area in 1990), native forests on Anjouan are strongly affected by a high level of harvesting that causes habitat fragmentation (Ibouroi, Cheha, Astruc, et al., 2018). More than 85% of the native forest surface area was harvested from 1972 to 1987 in Anjouan (compared to 53% on Mohéli for the same period: Weightman, 1987), a rate of habitat degradation that continues to increase (Amelaid et al., 2020). The currently high level of fragmentation on this island increases the species' vulnerability to extinction (Ibouroi, Cheha, Arnal, et al., 2018).…”
