Resumen
[ES] Los ecosistemas acuáticos están siendo fuertemente amenazados por las alteraciones derivadas de la crisis ambiental planetaria que tiene su principal motor en el cambio climático. Una de sus consecuencias más relevantes es la implicación que tiene sobre las comunidades microbianas, y en particular sobe los organismos autotróficos, de importante papel ecológico ya que son los productores primarios y por lo tanto la base de la red trófica de los sistemas acuáticos. Este estudio está orientado al análisis de la eclosión de la comunidad microbiana en los sedimentos presentes en la laguna del Hituelo, una laguna temporal ubicada en el municipio de Martos, en la provincia de Jaén, bajo diferentes condiciones de temperatura. Utilizamos para ello como herramienta la citometría de flujo debido a su idoneidad para el estudio de la comunidad autotrófica, su dinámica de eclosión y las diferentes poblaciones existentes en aguas continentales.
[EN] Aquatic ecosystems are being strongly threatened by alterations derived from the planetary environmental crisis that has its main engine in the climate change. One of its most important consequences is the involvement it has on microbial communities, and particularly on the autotrophic organisms, of an important ecological role, since they are primary producers and therefore the basis of the trophic network of aquatic systems. This study is oriented to the analysis of the hatching of the microbial community in sediments present in the wetland lake of Hituelo, a temporary pond located in the municipality of Martos, in the province of Jaen, under different temperature conditions. We used flow cytometry as a tool dueto its suitability for studying the autotrophic community, its hatching dynamics and the different populations existing in inland waters.
