Nowadays, more than half of the world's population lives in cities and this number is expected to reach 72% by 2050.

On the other hand, some species adapt to the anthropogenic environments because they obtain advantages of the urban matrix, using shelter or food available. Bats have ecological plasticity that allows them to settle in forest remnants in the cities or directly in the built environment. In this essay, we defend the importance of medium-sized cities as spaces for the conservation of biodiversity.
