Pontellid copepods, Labidocera spp., affected by ocean acidification: A field study at natural CO2 seeps
CO2 seeps in coral reefs were used as natural laboratories to study the impacts of ocean acidification on the pontellid copepod, Labidocera spp. Pontellid abundances were reduced by ∼70% under high-CO2 conditions. Biological parameters and substratum preferences of the copepods were explored to dete...
