Habitat Fragmentation and Genetic Connectivity in Arboreal Mammals
Quick fact
For arboreal mammals like the southern muriqui and some possums, a gap in the canopy as narrow as a few meters can be an insurmountable barrier, dramatically reducing gene flow between forest patches.
Why this is interesting
Imagine a forest chopped into tiny islands—how do tree-dwelling animals that never touch the ground find each other to mate?
