Alopecia in Bats from Tropical Urban Islands

This study investigated alopecia in bats from Batam City, capturing 417 bats across seven species, with an overall alopecia prevalence of 10.79%. The highest prevalence was observed in Pipistrellus tenuis (100%), Kerivoula pellucida (50%), and Macroglossus minimus (20%), attributed to small sample sizes. Larger sample sizes showed lower prevalence rates. Alopecia was more prevalent in fragmented forests in urban and periurban areas, linked to anthropogenic pressures. The study highlights the impact of habitat conditions on bat health in fragmented environments.
