ABSTRACT Thermal stability of bat roosts in tropical urban structures remains understudied despite its conservation relevance. We monitored two Colombian Caribbean fortresses, finding chambers with reproductive mormoopid colonies were 5°C–9°C warmer than unoccupied, peaking at 39°C. This first documented tropical urban ‘hot roost’ is critical for conserving cave‐specialist bats in cities.
Otálora‐Ardila et al. (Tue,) studied this question.
