description [EN] We analysed summer assemblages and the metacommunity structure of benthic microalgae and Cyanobacteria (BMC) living in pristine ecosystems in the Serranía de Cuenca (Central Spain), whose flora is not well-known. Our analyses were focused on both overall samples and some site subgroups (two large catchments, lotic vs lentic environments, plant vs mineral substrates). 379 taxa were recorded, with Diatoms, Chlorophytes and Cyanobacteria being the richest groups. The flora composition depended on conductivity and the percentage of forests in each sub-basin; even so, the composition was spatially homogeneous, reflecting the relatively low variability of the landscape. Taxonomic richness did not differ between inventory subgroups, but it was vulnerable to the somewhat higher values of low concentrations of nitrogen and phosphorus compounds. Two groups of BMC assemblages emerged in the territory: one of cosmopolitan Diatoms and Cyanobacteria, and another of Cyanobacteria, Diatoms and Chlorophytes associated with travertine. The structure of the metacommunity was governed by the contributions of space, catchment features and the local environment (chemical and biological); the relevance of biological factors, which are not usually analysed, was highlighted. Finally, we suggest the joint study of local ecology and metacommunity that is feasible with the many occurrence databases of many benthic organisms. Soon artificial intelligence and new taxonomic tools will allow faster and more comprehensive processing of the huge number of freshwater datasets already in existence, which will be a huge leap in ecological knowledge of benthic assemblages in the coming years.

El análisis se centró en el total de las muestras y en subgrupos de ellas (cuencas del Júcar o del Tajo, ambiente lótico o léntico, sustrato mineral o vegetal). Se inventariaron 379 taxones, siendo Diatomeas, Clorofitas y Cianobacterias los grupos más relevantes. La composición de la flora dependió de la conductividad y del porcentaje de bosques en cada subcuenca; aun así, la composición fue homogénea espacialmente, reflejo de la relativamente escasa variabilidad del paisaje. La riqueza taxonómica no difirió entre los subgrupos de muestras, pero resultó vulnerable al incremento de las bajas concentraciones de compuestos de nitrógeno y fósforo. Hubo dos grupos de comunidades de MCB: uno de Diatomeas y Cianobacterias cosmopolitas, y otro de Cianobacterias, Diatomeas y Clorofitas asociadas al travertino. La metacomunidad la estructuraron el espacio, las características de la cuenca hidrográfica y el ambiente local (tanto químico como biológico); el factor biológico, que habitualmente no se emplea en esos análisis, destacó también. Como conclusión, sugerimos el estudio conjunto de la ecología local y la metacomunidad bentónica, factible con las numerosas bases de datos de presencia-ausencia para muchos grupos de organismos. Pronto la inteligencia artificial y las nuevas herramientas taxonómicas permitirán un procesamiento más rápido y completo del enorme número de datos de agua dulce ya existentes, lo cual supondrá un gran salto en el conocimiento ecológico de las comunidades bentónicas en los próximos años.Peer reviewedAsociación Ibérica de LimnologíaConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202320232023info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/304296reponame:DIGITAL.CSIC.
