Resumen

In recent years, research on ocean acidification in CO2 vents has increased, but very few have considered the meiofaunal communities living in sandy substrates, despite their importance as bioindicators. Therefore, the aim of this work is to carry out a preliminary study of the meiofauna associated with sandy substrates in the acidified system of La Palma, Canary Islands, which includes coastal lagoons with very extreme environments. The results ob- tained based on abundance confirm a significant change in the meiofaunal communities in these coastal lagoons. We found an increase in bioindicator taxa of altered environments: oligochaetes, nematodes, copepods and, to a lesser extent, ostracods and acarids. While xenacelomorphs are the most affected by acidification as they are the only group with a decrease in abundance. All this indicates an alteration in the composition of the meiofaunal communities due to the extreme acidification in the coastal environment of La Palma
