In the Northern tropics, hurricanes can have detrimental effects on bat communities causing direct mortality and injury, and by altering the landscape and disrupting resource availability (i.e., food and roost sites). Islands are particularly vulnerable because they are isolated, closed systems. Therefore, with the predicted increase in frequency of major storms, understanding the response by bats in insular communities is vital. I examined the effects of Hurricane Maria on the bat community in Dominica. Maria was a category 5 storm that struck on 18 September 2017 causing substantial damage across the island. I measured changes in diversity and abundance for the entire bat community, and further examined effects on abundance, body condition and reproductive rate for the four most common species in three foraging guilds – Artibeus jamaicensis (frugivore), Monophyllus plethodon (nectarivore), Molossus molossus and Myotis dominicensis (insectivores). In general, Hurricane Maria had negative effects on the bat community. All guilds were negatively impacted but not all species, and frugivores showed the strongest negative responses. Maria negatively affected all the common species except M. molossus. Reduced abundance for common species, particularly frugivores (e.g., A. jamaicensis) resulted in a more even distribution and greater diversity post-Maria. The largest declines in abundance occurred in the frugivores, which I suggest was primarily due to loss of food and roosts. There was no change in body condition for any guild indicating that individuals that survived were able to obtain enough food. However, there was a significant decline in female reproductive rate for frugivores suggesting a trade-off between energy for survival and reproduction. A comprehensive understanding will require longer-term monitoring post-hurricane.
