Resumen:

Bacterioplankton is an often-underestimated component in aquatic environments, which has major implications for ecosystem functioning. Recent studies highlight its activity and diversity in lake systems. Lake Alchichica is no exception in this matter, and although most microbial surveys have addressed the activity and abundance of phytoplankton, the latest surveys in this maar lake have shed light on its taxonomically and metabolic complex composition. These microbial communities include heterotrophic picoplankton (microorganisms of <2 µm size) with high bacterial and archaeal diversity. The main approaches used to survey the water column of Lake Alchichica include epifluorescence methods, such as fluorescence in situ hybridization (FISH) and microscopic techniques, together with next-generation sequencing (NGS) methods using the 16S rRNA gene marker, and functional gene quantifications. Overall, these studies show how the hydrodynamics, depth, and physicochemical characteristics of the lake relate to the bacterioplankton taxonomic and functional diversity displaying spatial and temporal variations. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
