Brain transcriptome of gobies inhabiting natural CO(2) seeps reveal acclimation strategies to long‐term acidification
Ocean acidification (OA) is known to affect the physiology, survival, behaviour and fitness of various fish species with repercussions at the population, community and ecosystem levels. Some fish species, however, seem to acclimate rapidly to OA conditions and even thrive in acidified environments....

Ocean acidification (OA) is known to affect the physiology, survival, behaviour and fitness of various fish species with repercussions at the population, community and ecosystem levels. Some fish species, however, seem to acclimate rapidly to OA conditions and even thrive in acidified environments.

Here, we used the natural CO(2) seep in Vulcano Island, Italy to study the effects of elevated CO(2) exposure on the brain transcriptome of the anemone goby, a species with high population density in the CO(2) seep and investigate their potential for acclimation.
