Abstract

The effects of ocean warming and acidification on Eastern Mediterranean coastal benthic communities were studied in a long-term research using benthic mesocosms ('benthocosms'). Temperature and pH treatments complied with the near-past, present and predicted-future levels. While biodiversity indices did not change significantly with warming (+3 ºC) and acidification (-0.5 pH units), community composition shifted from native to non-indigenous species dominance, and the abundance of calcifying species increased. In the summer, community functions presented a shift from autotrophic to heterotrophic system.
