Resumen:

Three families, five genera, and six species of hydrophytes represent the floristic richness of Lake Alchichica. Five species are subaquatic (emerging rooted), while one is strictly aquatic (submerged rooted). Also, four species are halophile. This study?s collections increased the floristic inventory, adding four species to the previous reports, including one new record for Puebla state. The hydrophytes? presence and distribution are determined by environmental (altitude, climate, winds, and sediments), physicochemical (salinity, alkalinity, ion composition of water) factors, and the morphology of the lake. There are two types of plant communities: subaquatic vegetation comprised of emerging rooted: A. nevadensis, C. laevigatus, E. dombeyana, J. articus, and Juncus sp., predominant in shallow waters, and submerged vegetation, represented by submerged rooted R. maritima, towards deeper areas. Subaquatic and submerged vegetation predominates towards the NE of the lake due to a broader littoral zone, which allows its most significant presence. More than half of the species recorded (A. nevadensis, E. dombeyana, Juncus sp. and R. maritima) could disappear rapidly due to its scarcity and habitat loss caused by processes of natural and human desiccation. The information herein provided serves as the basis for future research to continue with the floristic inventory and constitutes a useful tool for decision-makers with conservation purposes of Lake Alchichica and its biota. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
