    Abstract:
    PREMISE: The interaction between ecological and evolutionary processes has been recognized as an important factor shaping the evolutionary history of species. Some authors have proposed different ecological and evolutionary hypotheses concerning the relationships between plants and their pollinators; a special case is the interaction and suspected coevolution among Agave spp. and their main pollinators, the Leptonycteris bats. Agave spp. have, in general, a pollination syndrome compatible with chiropterophily including floral shape and size, nocturnal nectar production, and nectar quality and sugar concentration. Our goal was to analyze the interaction Agave-Leptonycteris and its dynamics during three different climate scenarios. METHODS: We modeled the Agave-Leptonycteris interaction in its spatial and temporal components during the Pleistocene using Ecological Niche Models (ENMs) and three climate scenarios: Current, Last Glacial Maximum (LGM), and Last InterGlacial (LIG). Furthermore, we analyzed the geographic correlation between 96 Agave spp. and two of the Mexican Tequila bats, genus Leptonycteris. RESULTS: We found that Leptonycteris spp. interact with different Agave spp. over their migratory routes. We propose an interaction refuge in Metztitlán and Tehuacán-Cuicatlán areas, where Agave- Leptonycteris interaction has probably remained active. During the nonmigratory season, both bat species consume nectar of almost the same Agave spp., suggesting the possibility of a diffuse coevolution among Agave and Leptonycteris bats. CONCLUSIONS: We propose that in the areas related to migratory bat movements, each bat species interacts with different Agave spp., whereas in the areas occupied by nonmigrant individuals, both bat species consume nectar of almost the same Agave taxa.
