LOPEZ, Benjamín; NARANJO-GARCIA, Edna  and  MEJIA, Omar. Diversity patterns of Mexican land and freshwater snails: a spatiotemporal approach. Rev. Mex. Biodiv. [online]. 2022, vol.93, e933966.  Epub July 31, 2023. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2022.93.3966.

This study used a biogeographic approach to identify panbiogeographic nodes and evaluate the spatial diversity patterns of the Mexican continental gastropods. A total of 86 individual nodes and one generalized node were identified for the continental gastropods. Most grid cells showed low diversity values, except for 3 cells with diversity values greater than 10%, which can be considered hotspots. On the other hand, despite the different environments, land and freshwater snails showed similar historical and spatial distribution patterns.
