Bats and Mayan temples: Bat diversity and the potential for conservation of archeological zones in Yucatan, Mexico

Abstract The role of archeological zones in biological conservation has been highlighted because of their restrictions over land‐use change, size, and maintenance of upstanding vegetation. The Yucatan Peninsula in Mexico has over 2000 archeological zones amidst biological, ecological, and culturally diverse landscapes. However, due to population centers and tourism growth, the peninsula is experiencing high deforestation and habitat fragmentation rates. To explore the role of archeological zones in biological conservation, we focused on bat species because of their high mobility, use of human structures as refugia, and the ecosystem services they provide. Using mist nets and roost surveys, we compared the bat diversity in four highly visited archeological zones during the dry and wet seasons. In a total effort of 34,560 m 2 mist net hours, we found 23 species from six families and seven guilds, representing 53% of all bat species known from the Yucatan state, including two endangered species for Mexico: Mimon cozumelae and Micronycteris schmidtorum . We found between 12 and 19 species in each archeological zone, and the communities were similar between the four sites and between seasons. The Phyllostomidae family was dominant across all sites, accounting for 92% of all the captures. We also recorded 12 species across 52 diurnal and nocturnal roosts, suggesting that Mayan archeological structures could offer several advantages to bats despite the high visitation of tourists. Our results emphasize the need to conduct research beyond natural protected areas to complement conservation policies and incentivize the inclusion of archeological zones in Yucatan's bat conservation plans.
